The District 6 Project will replace and rehabilitate the sewer pipeline that extends from Pomona Avenue in the City of Costa Mesa and along Newport Blvd. to Pacific Coast Highway (PCH) in the City of Newport Beach. The work on the sewer pipeline will be completed using a variety of methods including pipe bursting, open-cut pipe replacement/realignment, and cured-in-place relining. Several maintenance access points will also be reconstructed or relocated. Access improvements involving surface modifications will be completed to improve safety and reduce risk when accessing the pipe for maintenance. 1.2 Purpose and Need for Project 1.2.1 Addendum Overview The California Environmental Quality Act (CEQA) requires public agencies to analyze and consider the environmental consequences of their decisions to approve development projects over which they exercise discretion.As lead agency,OCSD prepared a Program Environmental Impact Report(PEIR)for the OCSD Collection System Improvement Plan in compliance with CEQA(SCH#2006101018).In accordance with the State CEQA Guidelines,the Draft PEIR was prepared and distributed to public agencies and the general public by the OCSD on March 15, 2007, for a 45-day public review period. A Notice of Availability for public review was posted at the Orange County Clerk's Office,a public notice was published in the Orange County Register on Much 16,2007,and a Notice of Completion was filed with the State Clearinghouse of the Governor's Office of Planning and Research. The notices included a list of locations where the document was available for public review. Public comments on the Draft PEIR were also solicited at a public hearing that was held on April 3, 2007. No substantive comments on content of the Draft PEIR or significant environmental issues related to the proposed Plan were raised at the public hearing. On August 22, 2007, the County Board of Supervisors certified the PEIR, made findings, adopted a Statement of Overriding Considerations, adopted a Mitigation Monitoring and Reporting Program (MMRP), and approved the Collection System Improvement Plan,Job No.7-6 1.OCSD filed the Notice of Determination on August 23,2007. The District 6 Project was one of 19 collection system improvement projects analyzed in the PEIR. The Project is therefore a subsequent activity within the scope of the PEIR (CEQA Guidelines §15168). Subsequent activities in a PEIR must be examined in light of the PEIR to determine whether an additional environmental document must be prepared(CEQA Guidelines§15168(c)). During the design phase of the District 6 Project,minor changes to the project description were identified. An Addendum to a previously certified EIR is appropriate if some changes,additions,or clarifications are necessary,but no substantial new information or substantial changes to the project or circumstances would require major revisions to the previous EIR(CEQA Guidelines §§ 15168(c)(1), (c)(2); 15162; 15164). OCSD staff reviewed the PEIR and its MMRP, along with the District 6 Project details, to 1)determine whether any of the criteria requiring farther environmental review have been met,2)identify which mitigation measures in the PEIR and MMRP were applicable to the District 6 Project,and 3)consider if any topics required additional consideration. The results of this assessment are presented in Table 2-1 below. August 2016 1-1 1136054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL For each CEQA resource topic, the proposed project was evaluated to assess its potential to change the degree of impact described in the PEIR.Based on this analysis,OCSD staff identified eight topics that merit additional documentation due to the time that has passed since PEIR certification: (I) agriculture and forestry; (2) air quality; (3) biological resources; (4) cultural resources; (5) geology and soils; (6) greenhouse gas emissions; (7) hazardous materials; and (8) traffic and transportation. OCSD staff has determined that the District 6 Project is within the scope of the PEIR and that none of the criteria requiring further environmental review have been met(CEQA Guidelines §15168(c); 15162). Staff has prepared this Addendum to the Collection System Improvement Plan PEIR,including Chapter 2, Environmental Checklist,to document that no further environmental review is required. Asset forth below, pursuant to CEQA Guidelines §15168(c)(3),OCSD has incorporated the feasible mitigation measures from the 2007 PEIR into the District 6 Project. 1.2.2 Background/Need for Project The 2007 PEIR assessed the potential environmental impacts of 19 proposed collection system improvement projects that together comprised the Collection System Improvement Plan. These projects were proposed to address projected system deficiencies, as the systems aged or demands on the systems changed. The objectives of the projects included: • Upgrading the systems to serve the sanitation needs of OCSD's service area through 2030, • Ensuring compliance with State General Waste Discharge Requirements (GWDR) by providing capacity adequate to prevent sewer overflows,and • Implementing projects identified in the Capital Improvement Plan to ensure system maintenance and upgrades are scheduled and completed in a timely manner. The projects in the 2007 PEIR were identified through a capacity analysis of OCSD's trunk sewer system that was undertaken as part of its 2006 Strategic Plan Update. This analysis used growth projections and flow simulations for wet and dry weather to identify areas of potential capacity deficiencies by 2030. The projects included in the 2007 PEIR are designed to address these potential capacity problems(OCSD 2007). The District 6 Project was one of the 19 proposed projects in the 2007 PEIR. As described in the 2007 PEIR, the proposed District 6 Project would address potential capacity deficiencies in the sewer trunk running from Pomona Avenue in Costa Mesa and along Newport Blvd. to PCH in Newport Beach. The District 6 Project calls for upsizing approximately 1,000 LF of pipeline from 12-inch through 16-inch to 15-inch through 22-inch pipeline using the pipe bursting method, CIPP re-lining of approximately 1,000 LF of existing 12-inch and 15-inch pipeline, constructing approximately 678 LF of 18-inch diameter pipeline to relocate/upsiu an existing 15-inch diameter pipeline that will be abandoned in place,and other improvements in the City of Newport Beach(OCSD 2007).The portion of the District 6 Project in the City of Costa Mesa would require only minor upgrades to manholes,and would not require work on the pipeline itself. August 2016 1-2 113054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL 1.2.3 Purpose of Project The purpose of the District 6 Project is to replace and rehabilitate the sewer trunk line in the identified area through upsizing,pipe replacement, and pipe cleaning and repair. It will also improve access to the sewer trunk through upgrades and relocation of manholes to enable OCSD to continue pipe and system maintenance,thereby ensuring continued use of pipeline and protection of human and environmental health and safety through the prevention of system failures. 1.3 Proposed Project 1.3.1 Construction Methods Pipe Bursting Pipe bursting is the replacement of an existing pipe with a new pipe that is installed through"bursting"the existing pipe. To prepare for pipe bursting,the existing pipe will be cleaned to accommodate the bursting head,but does not need to be cleaned extensively. The new, larger pipe is pulled through the existing pipe by a bursting head, which breaks apart the old pipe and pushes it into the surrounding fill while simultaneously pulling the new pipe into place.Pipe bursting requires excavation of a bursting pit on either end of the pipeline segment,approximately 8 feet x 50 feet each.Bypass pumping will be required for the normal wastewater flows during the pipe bursting process. Open Cut Open cut construction will be used for installation of the new pipeline alignment from Manhole("MH")- 155 to MH-A. Open cut requires excavating a trench along the new alignment, dewatering(discharged to OCSD sewer system),and installing the new pipe.The trench required for open cut would be approximately 4-5 feet wide,with an average required work space of 25 feet x 200 feet.Open cut installation can occur at a rate of approximately 50 feet per day. Cured-In-Place Pipe Lining CIPP lining requires a resin-impregnated liner to be pulled or inverted through the segment of the pipe to be lined. The resin is then cured over 24 hours using hot water, steam, or high-intensity UV light. CIPP lining requires bypass pumping of existing wastewater flows during installation,and extensive cleaning is necessary prior to installation. However, no trenching or other excavation should be required for CIPP lining,as it can be installed through existing manholes. Manhole Access Manhole access will be improved by adding concrete collars around existing manholes and adding maintenance vehicle pullouts in vegetated areas adjacent to manholes. Bypass Pumpina Bypass pumping is required to divert sewage flow during construction on existing sewers,including during pipe bursting and CIPP. Bypass pump stations will be located near MH-135,MH-140,MH-165(new MH- A), and two near MH-170. Bypass lines will be located on the ground surface and in shallow trenches at road crossings.Bypass pumps are typically trailer-mounted suction-lift diesel-driven pumps.Bypass Pump Station lA(near MH-165)would be the primary pumping station,while Bypass Pump Stations 113 and 1 C would redirect flows entering the system at MH-140 and MH-135. A shallow pipe trench would be constructed for discharge piping for pipe bursting activities,while bypass discharge will be routed through an existing storm drain system from MH-170 to cross under Newport Blvd.,and then pumped back into the sewer system. August 2016 1-3 113054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL Bypass pumping generally requires redundant pumps, full-time operation of pumps and appurtenant equipment,monitoring and maintaining water surface to avoid upstream operational problems,and various outage plans,equipment testing, and permits. As noted in OCSD contract specifications, bypass pumping should not occur during rainy months(December-March). Abandon in Place Abandon in place consists of filling the pipeline with a cementitious grout, so that it is no longer used for conveying wastewater. Wastewater flows will be routed around abandoned pipeline through newly constructed segment. 1.3.2 Equipment/Staging Equipment required for the proposed District 6 Project may include,but is not limited to:trucks,excavators, backhoes,front-end loaders,dump trucks,diesel generators,water trucks,compactors,concrete trucks,pipe bursting head, truck-mounted suction-lift diesel pumps. Staging areas would require storage of pipes, equipment,and other materials. 1.3.3 Project Description The proposed project as described here is a refined version of the District 6 Project included in the 2007 PEIR. The project description below designates which sections of the pipeline will require which construction method previously identified in the 2007 PEIR, includes a small realignment of the pipeline to provide improved pipeline access with less potential environmental impact, and provides specifics of manhole improvements.The majority of the project,including its primary construction activities,will occur in three phases as described below. Figure 1-1 shows the proposed District 6 alignment. Phase 1: MH-020 to MH-155 Phase 1 will include the section of the District 6 sewer trunk from MH-020 to MH-155. This corresponds to the southern end of the project at Newport Blvd. near Catalina Drive (MH-020) to approximately 850 feet north of the intersection of Newport Blvd. and Hospital Road (MH-155). Pipeline improvements include pipe bursting along 892 LF and 744 LF of cured-in-place-pipe lining.Manhole improvements will replace MH-025, MH-135, and MH-140 with 60-inch manholes (existing manholes are 48-inches), and modification of MH-145 and MH-155 to bring their rims flush with grade and to replace their existing frames and covers.Manhole improvements will also include replacing sidewalks and installing maintenance vehicle pullouts. Table 1-1 shows the pipeline and manhole improvements to be made in Phase 1. Three bursting pits will be excavated for pipe bursting activities—one near MH-025, one between MH-135 and MH-I40, and one near MH-145. Additionally, a coupling access pit will be excavated between MH-140 and MH-145 new the southwest comer of the intersection of Newport Blvd.and Hospital Road.

August 2016 1-6 1136054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL Phase 2: MHA 55 to MH-A Phase 2 of the District 6 Project includes the start of the pipeline realignment that ultimately keeps the pipeline along the eastern shoulder of Newport Blvd. until it crosses to the western side of Newport Blvd. This new alignment begins at MH-155, which will be improved as described in Phase 1, and follows the roadway to the new MH-A. Construction of the Phase 2 portion of the new alignment will require 688 LF of open cut. This new segment of pipeline will run between the existing guardrail and the existing drainage swale within the southeastern edge of this portion of Newport Boulevard. The existing pipeline will be abandoned in place,as will the two manholes along the old alignment(MH-160 and MH-165).Abandon in place consists of filling the pipeline with a cementitious grout. Table 1-2 provides a summary of the Phase 2 pipeline and manhole improvements.Manhole improvements include constructing rolled curbs,installing maintenance vehicle pullouts,and relocating road signs.

MH-155 activities included in both Phase I and Phase 2 tables. b. MH-A activities included in both Phase 2 and Phase 3 tables. Phase 3: MH-A to MH-210 Phase 3 of the District 6 Project covers the pipeline improvements between the new MH-A to MH-185.At MH-A the new pipeline alignment rejoins the existing pipeline. The pipeline crosses Newport Blvd. from MH-A to approximately the previously abandoned MH-170,which will be removed and 20 LF of 15-inch VCP pipeline installed to connect the existing pipeline to the existing MH-170.From MH-A to the existing MH-170, the pipeline will be cleaned and lined using CIPP lining. The pipeline leaves the Caltrans right- of-way after MH-170, and runs approximately north and northwest to MH-180 new the intersection of Superior Avenue new Industrial Way and approximately west-northwest to MH-185 at 16th Street. The sections of pipeline run under parking lots, buildings, and alleys,making major construction challenging. However, analysis shows that only minor repairs are necessary in these sections of Phase 3. Spot repairs will occur as needed from MH-170 to MH-180 to address pipe issues such as cracks and laterals. August 2016 1-7 1136054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL There are no pipeline improvements required between MH-180 and MH-210. This section of the pipeline runs from MH-185 at l6th Street north to Ohms Way at MH-190,along Ohms Way to Farad Street at MH- 195, and to a parking lot approximately halfway between Farad Street and West 17th Street, at MH-200. The pipeline turns east to Pomona Avenue, where both MH-205 and MH-210 are located. The District 6 sewer[rank project terminates at MH-210 on the eastern side of Pomona Avenue. Phase 3 manhole improvements include removal of the abandoned MH-170 and lining through the manhole to provide continuous pipe from MH-165 to MH-170,as well as replacement of the existing 24-inch frames and covers on MH-I80 though MH-200 and replacement of the existing 36-inch frames and covers on MH- 205 and MH-210 with locking, composite frames and covers.

August 2016 1-8 113054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL 1.4 Environmental Commitments and Mitigation Measures 1.4.1 Environmental Commitments from 2007 PER The 2007 PEIR contains environmental commitments within the impact analysis that will be adhered to as part of project implementation. These commitments are based on compliance with local ordinances or standards to which construction projects are expected to adhere. Noise Section 3.9.2 of the 2007 PEIR describes the local ordinances that restrict the time that construction activities can occur.The project falls within the City of Newport Beach and the City of Costa Mesa.Because primary construction activities will occur within the City of Newport Beach, which contains more conservative construction hours than the City of Costa Mesa, construction activities will be limited to between the hours of 7:00 am and 6:30 pm on weekdays and 7:00 am and 6:00 pm on Saturdays,with no construction activities occurring on Sundays or federal holidays.This is in compliance with City of Newport Beach Municipal Code Ordinance No. 2001-4, Chapter 10.28, Section 10.28.040-Construction Activity Noise Regulations. Night work may be required by the City of Newport Beach in order to reduce the length of the construction schedule.If the request for night work is made,the City will make the request in writing noting the cbange from their City Ordinance. 1.4.2 Mitigation Measures from 2007 PER Applicable to Proposed Project The 2007 PEIR assessed potential impacts to 17 resource areas, the results of which are summarized in Table 2-1 below. Pursuant to CEQA Guidelines §15168(c)(3), OCSD has incorporated the feasible mitigation measures verbatim from the 2007 PEIR into the District 6 Project as follows: Table 1-4: 2007 PEIR Mitigation Measures Applicable to the District 6 Project' 2007 PEIR Mitigation Measures Applicable to the District 6 Project Air Quality Mitigation Measure 3.2.1a: Contractors will maintain equipment engines in proper tune and operate construction equipment so as to minimize exhaust emissions. Mitigation Measure 3.2.1b: During construction,trucks and vehicles in loading or unloading queues will keep engines off,when not in use,to reduce vehicle emissions. Mitigation Measure 3.2-2: Contractors will reduce fugitive dust emissions through implementation of the following dust control measures: • Cover all trucks hauling soil,sand, or other loose materials • Apply water as necessary on all unpaved access roads, parking areas,and staging areas at construction sites • Sweep all paved access roads, parking areas,and staging areas at construction sites with sweepers • Water or apply nontoxic soil stabilizers to exposed soil stockpiles or areas disturbed by construction activities which produce dust Limit traffic speeds on unpaved roads to 15 mph This table includes mitigation measures verbatim from the PEIR. August 2016 1-9 113W54.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL Bioloeical Resources Mitigation Measure 3.3-1: Evaluation of impacts to special-status plants,birds,mammals,and amphibians and reptiles will occur at the project level.Specifically,all areas of natural habitat within the footprint of proposed construction activities with potential to support special-status biological resources will be surveyed according to standard protocol. Where special-status biological resources are identified within the project footprint, appropriate avoidance, minimization, and mitigation measures will be implemented. Depending on the special-status biological resources present, measures could include the following: Where rare plants are identified within the project footprint, the following avoidance, minimization, and mitigation measures will be implemented: • Project design will be evaluated to determine if an exclusionary zone can be established around rare plant populations; where feasible, this will be implemented, and construction activities will be relocated or modified to avoid impact. • If rare plant populations cannot be avoided, appropriate salvage of plant propagules will be implemented, and suitable habitats for transplanting or re-establishing population will be identified and implemented. • Mitigation will include an analysis of suitability of alternative locations and identification of suitable propagation techniques. • Procurement of conservation easements will be implemented for alternative suitable habitats if the habitats are not already secured with conservation status. Where special-status nesting birds are identified within the project footprint, the following avoidance, minimization, and mitigation measures will be implemented: • Project design will be evaluated to determine if a 500-foot minimum exclusionary zone can be established around active bird nests; where feasible, this will be implemented, and construction activities will be relocated or modified to avoid impact. • If nesting birds or active nest sites cannot be avoided,construction will be timed to avoid the active nesting season (February to August), and construction activities will not commence in the vicinity of nests until young have Fledged. Where special-status mammals or bat roosts are identified within the project footprint, the following avoidance, minimization,and mitigation measures will be implemented: • Project design will be evaluated to determine if a 500-foot minimum exclusionary zone can be established around active bat roosts; where feasible, this will be implemented, and construction activities will be relocated or modified to avoid impact. • Project design will be evaluated to determine if direct impacts to habitats supporting small mammals can be avoided with an exclusionary zone;where feasible,this will be implemented,and construction activities will be relocated or modified to avoid impact. • Where avoidance is not feasible,trapping or hazing of special-status mammals to remove them from the project site will be implemented, and individuals will be relocated to suitable habitat nearby; temporary fencing will be installed to prohibit species from returning to the construction zone. • If construction adjacent to bat roosts cannot be avoided,construction will be timed to avoid the parturition period(February to August),and construction activities will not commence in the vicinity of maternity roosts until young are weaned. • If construction must occur during the parturition period,then active bat roosts will be excluded prior to onset of breeding. Where special-status amphibians and reptiles are identified within the project footprint, the following avoidance, minimization,and mitigation measures will be implemented: • Project design will be evaluated to determine 0 direct impacts to habitats supporting amphibians or reptiles can be avoided with an exclusionary zone; where feasible, this will be implemented, and construction activities will be relocated or modified to avoid impact. • Where avoidance is not feasible, trapping or hazing of special-status amphibians or reptiles to remove them from the project site will be implemented,and individuals will be relocated to suitable habitat nearby; temporary fencing will be installed to prohibit species from returning to the construction zone. August 2016 1-10 113,5054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL Mitigation Measure 3.3-2: To avoid impacts to aquatic fisheries,best management practices will be implemented to avoid contaminant runoff from construction practices.This will include the following: • Equipment will not be operated in areas of ponded or lowing water.Stationary equipment such as motors, pumps, generators, and welders will be located a minimum of 200 feet outside aquatic and wetland habitats;construction staging areas,stockpiling,and equipment storage will be located a minimum of 200 feet outside aquatic and wetland habitats. • Construction vehicles and equipment will be checked periodically to ensure that proper working conditions with no potential for fugitive emissions of oil and other hazardous products exists. Refueling or lubrication of vehicles and cleaning of equipment, or other activities that involve open use of fuels, lubricants, or solvents,will occur in upland locations at least 200 feet away from aquatic or wetland habitats. • Temporary sediment-retention structures, hay bales, or silt fencing will be placed downstream of construction areas; sediment-retention devices will prevent sediment-laden water from draining offsite; sediment-retention devices structures will be maintained and repaired after flood events. Mitigation Measure 3.3J: Direct impacts to jurisdictional areas including wetlands generally will be avoided by identifying these communities at the project analysis level and designing project components to avoid these areas. However, if impacts to jurisdictional wetlands cannot be avoided,then the following mitigation will be implemented: • Delineation of affected jurisdictional sites will be implemented and impacts analyzed;this information will support permit applications to the U.S.Army Corps of Engineers(USAGE)under Section 404 of the Clean Water Act. • A proposed mitigation plan to compensate for impacts to jurisdictional areas will be developed and approved by the USACE;it will be implemented to compensate for impacts. • To avoid indirect impacts to jurisdictional areas from contaminant runoff, Mitigation Measure 3.3-2 will be implemented. Cultural Resources Mitigation Measure 3.4.1: During preliminary design,a Registered Professional Archaeologist(RPA)will complete a literature review using the archives of the South Central Coastal Information Center of the California Historical Resources Information System (CHRIS), located at California State University Fullerton,and other sources as needed to identify previous cultural resoumes studies and previously recorded archaeological sites within close proximity to the project alignment.The literature search will also include a search of the Sacred Lands Database maintained by the California Native American Heritage Commission (NAHC). Using the results of the literature review in part, the archaeologist will develop a cultural resources sensitivity map for the project alignment,followed by a determination of specific areas of the project that may require preconstruction survey, subsurface testing, or construction monitoring. Cultuml resources identified as a result of the literature review, field survey, testing, or construction monitoring will be evaluated by a Registered Professional Archaeologist to determine whether they meet the criteria for designation as a historical resource(14 CCR§4850,PRC§21084.1.14 CCR§15064.5(3))ore"unique archeological resource" as defined in PRC§21083.2. If resources are present on state lands, Office of Historic Preservation(OHP)will be consulted (PRC § 21083.2). For sites within project alignment where human remains have been previously documented,the Sanitation District would enter into a written agreement between an archaeological consultant,to be retained by the Sanitation District, and a Native American representative prior to construction in the vicinity of these sites.This agreement would specify terms as to the treatment and disposition of the human remains,and will define "associated burial goods"with reference to PRC § 5097.94, 5097.98, and 5097.99 and Health and Safety Code§7050.5. Mitigation Measure 3.4-2a: Subsurface construction has the potential for exposing significant subsurface cultural resources.Due to the likelihood of encountering cultural resources,the Sanitation District will implement the following prior to commencement of construction activities: • Prior to construction,contractors,and Sanitation District staff will receive an archaeological orientation from a professional archaeologist regarding the types of resources that could be uncovered during construction activities and the identification of these resources.The orientation also will cover procedures to follow in the case of any archaeological discovery. August 2016 1.11 1136054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 1 Project Description FINAL Mitigation Measure 3.4-2b: If cultural resources are encountered at any time during project excavation,construction personnel will avoid altering these materials and their context until a qualified archaeologist has evaluated the situation. Project personnel will not collect or retain cultural resources. Prehistoric resources include,but are not limited to,chart or obsidian flakes, projectile points,mortars and pestles,dark friable soil containing shell and bone,dietary debris, heat-affected rock, or human burials.Historic resources include stone or adobe foundations orwalls;structures and remains with square nails,and refuse deposits(glass,metal,wood,ceramics)often found in old wells and privies. Mitigation Measure 3.4-2c: In the event of accidental discovery or recognition of any human remains, the county coroner will be notified immediately, and construction activities will be halted.

Lane closures will be minimized during peak traffic hours. Mitigation Measure 3.12.2f: Where road closures are necessary for construction of sewer improvement projects,signage will be posted informing motorists of road closures and delineating suitable detours, both prior to and during the duration of construction activities. Prior to initiating a road closure,coordination with local jurisdictions,including Caltrans,will occur. 1.5 Permits/Approvals Required Encroachment permits will be required from Caltrans and the City of Newport Beach, while a flood encroachment permit will be required from the Orange County Department of Public Works Flood Control District. Permits will require traffic control plans in addition to the permit applications and materials. Permits generally take between 2 and 8 weeks for local agency review and 2 to 3 months for Caltrans review,but may take longer depending on the size of the project. 1.6 CEQA Process/Addendum Requirements The cnviromnental checklist below was prepared to evaluate the potential effects of the revised District 6 Project pursuant to CEQA Guidelines §15168(c)and 15162. Pursuant to CEQA Guidelines §15168(c): "Subsequent activities in the program must be examined in the light of the program EIR to determine whether an additional environmental document must be prepared. (1) If a later activity would have effects that were not examined in She program EIR, a new Initial Study would need to be prepared leading to either an EIR or a Negative Declaration. (2) If the agency finds that pursuant to Section 15162, no new effects could occur or no new mitigation measures would be required, the agency can approve the activity as being within the scope of the project covered by the program EIR, and no new environmental document would be required. The conditions in CEQA Guidelines §15162 include the following: (1) Substantial changes are proposed in the project which will require major revisions of the previous EIR or negative declaration due to the involvement of new significant environmental effects or a substantial increase in the severity of previously identified significant effects; (2) Substantial changes occur with respect to the circumstances under which the project is undertaken which will require major revisions of the previous EIR or Negative Declaration due to the involvement of new significant environmental effects or a substantial increase in the severity ofpreviously identfed significant effects; or (3) New information ofsubstantial importance, which was not known and could not have been known with the exercise of reasonable diligence at the time the previous EIR was certified as complete or the Negative Declaration was adopted,shows any of the following: Note:Mitigation Measure 3.12-lk not applicable because District 6 Project activities will not occur within a railroad right of way. August 2016 1-16 113W54.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL (A) The project will have one or more significant effects not discussed in the previous EIR or negative declaration; (B) Signifcant effects previously examined will be substantially more severe than shown in the previous EIR; (C) Mitigation measures or alternatives previously found not to be feasible would in fact be feasible, and would substantially reduce one or more significant effects of the project, but the project proponents decline to adopt the mitigation measure or akernative;or (D)Mitigation measures or alternatives which are considerably different from those analyzed in the previous EIR would substantially reduce one or more significant effects on the environment, but the project proponents decline to adopt the mitigation measure or alternative. Pursuant to CEQA Guidelines §15164(a): "A lead agency or responsible agency shall prepare an addendum to a previously certified EIR if some changes or additions are necessary but none of the conditions described in Section 15162 calling for preparation of a subsequent EIR have occurred." Based on the analysis in the environmental checklist,OCSD determined that none of the criteria requiring farther environmental review were met,and that an Addendum to the 2007 PEIR was appropriate pursuant to CEQA Guidelines§I5164.Specifically,OCSD determined that(1)the revised District 6 Project does not propose substantial changes to the project as described in the 2007 PEIR, (2) the District 6 Project would not create any new significant environmental impacts or a substantial increase in the severity of significant effects identified in the 2007 PEIR, and(3)the mitigation measures in the 2007 PEIR would be sufficient to address any potential environmental impacts of the District 6 Project. Since adoption of the 2007 PEER,the CEQA Guidelines have added a requirement to analyze greenhouse gas(GHG)impacts,which has been completed for the District 6 Project.These changes have been included in this Addendum. Chapter 2 Environmental Checklist 2.1 Environmental Analysis for District 6 Sewer Trunk Relief This chapter acts as the Environmental Checklist for the revised District 6 Project. Table 2-1 indicates,by resource area, the original findings of the 2007 PEIR and the findings for the revised District 6 Project. Applicable mitigation measures from the 2007 PEER are listed,with descriptions of each mitigation measure found in Section 1.4.1, above. A discussion describing the justification for each finding is also provided following the table. For those resources areas where additional information or analysis was completed for this Addendum, additional discussion is included in the justification discussion. For those thresholds that were identified as less-than-significant or no impact in the Initial Study (Appendix B of the PEIR), no additional analysis was completed in the PEIR. The PEIR Impact Statement column says"N/A"for these thresholds.

Does the project Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL 2.1.1 Aesthetics There are no scenic vistas or state scenic highways in the project area. Construction activities will be temporary and will take place in developed areas. These activities will not negatively affect the existing visual character or quality of the site or its surroundings permanently. The District 6 project will also not create any new permanent source of light or glaze because the finished project will be primarily underground, and does not include lighting or strongly reflective surfaces. Some existing lighting may be relocated to accommodate the project, but will be moved new its current location; therefore such action will not result in a new source of light. Temporary construction lighting may be necessary,but any such lighting will be directed away from residences in compliance with the applicable municipal codes. Therefore,the level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.2 Agriculture and Forestry There is no existing farmland or forests/timberland in the project area,therefore the District 6 project will not affect farmland or forestry resources. Due to changes to the CEQA Guidelines since adoption of the 2007 PEIR, additional discussion is included here. Additional Aarlculture and Forestry Analysis Since the adoption of the 2007 PEIR, the CEQA Guidelines have been updated to include the following question related to potential impacts to agriculture and forestry resources: Would the Project conflict with existing zoning for,or cause rezoning of,forest land,timberland,or timberland-zoned Timberland Production? The District 6 Project is not located within an area zoned for forest or timberland(City of Newport Beach, 2015;Costa Mesa, 2015).As such, it would not conflict with existing zoning,nor would it cause rezoning of, forest or timberland. Therefore, there would be no impact from the District 6 Project on forests or timberland. 2.1.3 Air Quality The construction activities included in the revised District 6 Project me typical construction activities that were described in the 2007 PEIR. Potential air quality impacts we a result of these construction activities, rather than a long-term impacts from operation of the rehabilitated sewer trunk line. The 2007 PEIR evaluated all projects in a shorter timeframe than the projects are actually being implemented.For example, the District 6 project was initially scheduled to be implemented between 2008 and 2010. The District 6 project is now scheduled to be implemented in 2016 and 2017. The extended timeline for the projects included in the 2007 PEIR have likely reduced the cumulative air quality impacts because fewer project components would be under construction at the same time,reducing the sources of construction emissions at a given time. Project-level analysis was conducted for the District 6 Project for air quality and greenhouse gases(GHGs), and included as Appendix B. Results from the air quality portion of this analysis are summarized immediately following this table,while the results from the GHG analysis have been summarized following Table 2-4. Additional Air Quality Analysis An air quality analysis was completed for this Addendum to consider changes to the air basin,and updated project information including refined construction methodology and final repair and rehabilitation designs. This new Air Quality analysis has been included as Appendix B and is summarized here.As described in the OCSD Collection System Improvement Plan PEIR,the project is located in the South Coast Air Basin, which is in attainment for SO2, N2O, PMIQ, and lead, in non-attainment for 03 and PM2.5, and in August 2016 2-24 1136054.1 Addendum to the Collection System Improvement Plan PER District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL maintenance for CO. Emissions associated with the District 6 project were modeled using California Emission Estimator Model (CalEEMod) Version 2013.2.2 to determine the daily maximum and annual average for criteria pollutant emissions and total annual GHG emissions. Modeling results were then compared to applicable South Coast Air Quality Management District(SCAQMD)standards to determine the potential for significant air quality impacts. As shown in Table 2-2, there were no exceedances for criteria pollutants anticipated during construction of the District 6 project.No long-term operational impacts are anticipated for this project because once construction is complete, maintenance of the sewer pipeline will be consistent with current maintenance of the existing pipeline.No additional emissions are anticipated above current conditions as related to operation and maintenance.

No No No No No No Each of the CEQA Guidelines for Air Quality were reevaluated following modeling of the District 6 project, and results compared to the findings presented in the PEIR.A summary of this analysis is presented here: Would the project conflict with or obstruct implementation of the applicable air quality plan? SCAQMD's Air Quality Management Plan(AQMP)is the applicable air quality plan within the Study Area for the District 6 Project.The bulk of the emissions associated with the District 6 Project would result from construction activities,and as shown in Table 2-2,above,construction emissions from the District 6 Project would not exceed applicable air quality thresholds. The Region currently exceeds air quality standards for ozone(03)and PM2.5,both of whose primary sources are vehicle and other mobile emissions. Operation of the District 6 Project would not result in a substantial increase in vehicle or mobile emissions from existing conditions, because the operation and maintenance of the District 6 Project would be similar in nature, extent, and frequency as the current operation and maintenance of the existing alignment. The District 6 Project would not conflict with or obstruct implementation of the applicable air quality plan. Potential air quality impacts are less severe than those in the 2007 PEIR. Would the project violate any air quality standard or contribute substantially to an existing or projected air quality violation? As shown in Table 2-2,above,construction of the District 6 Project is not anticipated to result in emissions exceeding applicable air quality standards. The Region is in non-attainment for ozone and PM2.5, which are primarily a result of vehicle and mobile sources.Operation of the District 6 Project would not result in a substantial increase in vehicle or mobile emissions from existing conditions,because the operation and maintenance of the District 6 Project would be similar in nature, extent, and frequency as the current operation and maintenance of the existing alignment. The Project, therefore, would not significantly August 2016 2-25 1136054.1 Addendum to the Collection System Improvement Plan PER District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL contribute to overall ozone and PM2.5 emissions. No new impacts associated with the violation of air quality standards would occur. Due to the Region's non-attainment for ozone and PM2.5, applicable air quality mitigation measures included in the PEIR shall be employed to minimize particulate emissions during the District 6 Project(refer to Section 1.4.2 of this Addendum).These include Mitigation Measures 3.2-la, 3.2-lb, and 3.2-2. The level of impact would not increase from those levels identified in the 2007 PEIR. Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-attainment under an applicable federal or state ambient air quality standard(including releasing emissions,which exceed quantitative thresholds for ozone precursors)? The South Coast region is in non-attainment for ozone and PM2.5. Based on the air quality analysis in Appendix B, potential emissions from truck traffic associated with construction of this project would represent insignificant sources of pollutants contributing to the overall PM2.5 emissions. The District 6 Project would not generate a cumulatively considerable net increase of ozone or PM2.5, the two criteria pollutants for which the region is in non-attainment. Therefore, the District 6 Project would not have significant cumulative air quality impacts for criteria pollutants for which the region is in non-attainment. The level of impact would not increase from those levels identified in the 2007 PEIR. Would the project expose sensitive receptors to substantial pollutant concentrations? Sensitive receptors in the Study Area include a library, a park,three places of worship, a hospital, senior living community, and a school. As shown in Table 2-2, the temporary increase in criteria air pollutant emissions during construction would not exceed SCAQMD's applicable air quality standards. The construction period will last approximately eight months, after which construction-related emissions will cease. Operation of the District 6 Project would result in minimal emissions consistent with the existing operation of the line, and are not anticipated to result in long-teen operational impacts that conflict with SCAQMD air quality standards. Therefore, the District 6 Project would not have a significant impact to sensitive receptors during construction or operation. The level of impact would not increase from those levels identified in the 2007 PEIR. Would the project create objectionable odors affecting a substantial number of people? The District 6 Project would be expected to create some objectionable odors as a result of modification of the existing sewer lines. Currently,OCSD investigates and trucks all odor complaints,performing cleaning and/or repairs as appropriate, and would continue this practice. As part of its operational activity, OCSD injects sodium hydroxide, hydrogen peroxide, ferrous chloride, and magnesium hydroxide at various locations in the collection system to control odor. Construction contractors are required to follow a site- specific odor control plan to minimize odors during rehabilitation activities.As explained in the 2007 PER odor control could include monitoring, ventilating, chemical application, material containment limiting atmospheric exposure, and activity staging to minimize odor impacts. Therefore, impacts associated with the creation of objectionable odors affecting a substantial number of people would be considered less than significant. The level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.4 Biological Resources The District 6 project is unlikely to cause any impacts to biological resources because of its location in a developed area, placement within the roadway right-of-way, and the nature of the project. Existing vegetation along the roadway and at manholes where new excavation,pavers, and vehicle pullouts would be constructed is primarily non-native ice plant. Activities in these areas will therefore not impact species movement or nursery sites, which are unlikely to be dependent on this non-native monocultare species because it provides minimal habitat benefits.As described below,a site visit was conducted to confirm the August2016 2-26 113054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL location of project activities and verify that dominant vegetation was non-native iceplant in areas where vegetation would be disturbed. While it is unlikely that special status biological resources are found in the project area due to location and lack of significant amounts of open space, the most recent observation and survey of the site found one species of interest: Aphanisma blitoides. However, this sighting was from 1934. In compliance with Mitigation Measure 3.3-1, a site visit was conducted to survey natural habitat within the footprint of proposed project activities. As described below, the only natural habitat near the alignment is a drainage Swale adjacent to Newport Blvd.between MH-155 and MH-165.This Swale would not be impacted by the District 6 Project because the pipeline rehabilitation and upgrades are designed specifically to avoid impacts to this swale.No other portions of Mitigation Measure 3.3-1 were triggered. The District 6 Project is not located new aquatic fisheries,but may result in some runoff entering the storm drain during construction,which may enter a fishery through the storm system. Mitigation Measure 3.3-2 will implement best management practices to avoid contaminant runoff from construction practices.There are no jurisdictional areas in the project area. Nonetheless,Mitigation Measure 3.3-2 will be implemented to avoid indirect impacts to jurisdictional areas from contaminant runoff. Realignment of the pipeline through MH-155 to MH-A will move the pipeline to the area between the existing guardrail along Newport Boulevard and the slope of the swale,with the old alignment abandoned in place.Abandoning the pipeline in place will avoid impacts to wetland or riparian habitat along the swale.The project will not conflict with local policies or ordinances, and is located outside the bounds of the Orange Coastal/Central Natural Community Conservation Plan, thereby avoiding any impacts to these policies and plans. Therefore, the level of impact would not increase from those levels identified in the 2007 PEIR. Additional Bioloplcal Resources Analysis As required under Mitigation Measure 3.3-1, a site walk was conducted on May 1, 2015 along the final pipeline alignment to evaluate natural habitat within the footprint of the proposed construction activities. Limited vegetation was identified within the construction footprint of the new alignment. As shown in the photos in Appendix C (Figures 1-17), vegetation along the alignment is primarily non-native iceplant (carpobrotus edulis). The site visit confirmed that staging areas,pipeline trenches,and pits would also be located in non-native iceplant-dominated areas. For the District 6 Project, the only native habitat area is located along the swale between MH-155 and MH-165 (see Appendix C, Figures 9-10). Construction of the new alignment would occur between the existing guardrail(which would be removed and replaced)and the slope of the swale itself. As shown in the photos in Appendix C, this area contains limited native grasses. During construction, protective measures would be implemented for embankment protection, limiting construction impacts on the Swale.The area would be restored upon completion of construction. To simplify maintenance activities, the Project was designed to abandon MH-160 in place. Abandoning MH-I60 also avoids impacts to the natural habitat around the swale. As shown in Appendix C(Figure 8), the access point from Old Newport Boulevard is primarily non-native vegetation. The site visit confirmed that there are existing trails from Old Newport Boulevard to MH-160,which could be used by construction crews during abandonment of MH-160,and therefore no substantial disturbance to vegetation would occur during abandonment of this manhole. Proposed construction and maintenance activities would not contribute to substantial increases in ambient noise due to existing noise from Newport Boulevard and surrounding developed areas.The area surrounding MH-170 and ABAN-MH,which is not located within landscape or roadway ROWS, would be disturbed by the District 6 Project(see Appendix C, Figure 11). While this area is not as dominated by iceplant as the eastern side of Newport Boulevard, it is primarily non-native habitat,comprising iceplant,low-lying shrubs,and palm trees. However,no native or sensitive vegetation would be impacted by construction activities at MH-170 and ABAN-MH. Therefore, the level of impact would not increase from those levels identified in the 2007 PEIR. August 2016 2-27 113W54.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL All areas disturbed by the District 6 Project would be revegetated in accordance with the Landscape Plan, also provided in Appendix C. 2.1.5 Cultural Resources It is unlikely that there are any cultural resources within the project area that will be encountered or impacted by the project because project activities consist of cleaning or replacing existing pipelines,and construction of new pipelines will occur within existing roadways or in previously disturbed areas.However,the project lies within archaeologically and historically significant areas, so there is a possibility that there could be impacts to cultural resources. Because of the higher chance of encountering cultural resources through excavation associated with the project,Mitigation Measures 3.4-1 through 3.4-2c will be implemented. To comply with Mitigation Measure 3.4-1, a project-level Cultural Resources Assessment(see Appendix D) was conducted in September 2014,the results of which are discussed below. The project is located within a developed area, and will be constructed within and immediately adjacent to the roadway and existing pipelines,so there we no historical resources to encounter.Therefore,the level of impact would not increase from those levels identified in the 2007 PEIR. Additional Cultural Resources Analysis To implement Mitigation Measure 3.4-1, a Cultural Resources Assessment was developed for the District 6 Project,and is summarized here.The complete report has been included as Appendix D.The Study Area is located in an area that has been occupied by humans for thousands of years. At the time the Spanish settled in the Study Area,it was occupied by the Gabrielino people,with a neighboring group,the Juaneiio, in central Orange County. A cultural resources records search and literature review at the South Central Coastal Information Center(SCCIC)was conducted to determine if the Study Area has been subject to a cultural resources survey and if any cultural resources had been recorded within a one-mile radius of the project. In addition, the Native American Heritage Commission (NAHC) was notified about the project, and a Sacred Lands Inventory was conducted to determine if any cultural resources were located within the Study Area. Nine tribes were identified as affiliated with the area, and were contacted for additional information on the history and prehistory of the area. Finally,a vehicular survey was conducted along the pipeline alignment. Records indicated the presence of seven cultural resources on or within one-half mile of the project alignment, none of which were within the Area of Potential Effects (APE). Four of these sites were shell middens,one was a church,one an office building,and one was a yacht.These resources are listed in Table 2-3.Native American contacts indicated that there was potential for cultural resources because the project was located"in and around a sensitive area where traditional territories of the Gabrieleno still exist'.While the site visit indicated that there were no historical resources that would be impacted by the District 6 Project,the presence of recorded prehistoric archaeological sites near the alignment suggests the potential for other,unrecorded,prehistoric resources within the pipeline alignment.Overall,the alignment was found to be moderately to highly sensitive for cultural resources(see Figure 2-1).

Proposed MM-1 (see page 10 of Cultural Resources Assessment in Appendix D) generally reinforces the actions required under (and me not considerably different from) the PEER Mitigation Measures; additional text has been added to Mitigation Measure 3.4- 2a to clarify archeological and Native American monitoring during construction. Subsequent evaluation found that the existing District 6 Trunk sewer pipeline was determined not to meet the criteria necessary to be identified as a historical resources as defined by 14 CCR §4850, PRC §21084.1, 14 CCR §15064.5(3) of CEQA(see page 8 of July 11, 2015 letter in Appendix D); therefore, proposed MM-2 (see page 11 of Cultural Resources Assessment in Appendix D) was determined to be not applicable to the Proposed Project.Revised Mitigation Measure 3.4-2a is provided below,with additions shown in underline. Revised Cultural Resources Mitigation Measure Mitigation Measure 3.4-2a: Subsurface construction has the potential for exposing significant subsurface cultural resources. Due to the likelihood of encountering cultural resources, the Sanitation District will implement the following prior to commencement of construction activities: • Prior to the issuance of the first aradina permit and/or action that would permit Project site disturbance.the Contractor shall provide written evidence to the Sanitation District that the Contractor has retained a aualified Archaeologist to observe creche activities and to salvage and catalogue archaeological resources,as necessary.The Archaeologist shall be present at the ore-arede conference:shall establish Procedures for archaeological resource surveillance: and shall establish, in cooperation with the Contractor,procedures for temporarily halting or redirecting work to permit the sampling,identification,and evaluation of the artifacts, as appropriate. If the archaeological resources are found to be significant(as determined by the Arohaeolonist). the Archaeologist shall determine appropriate actions, in cooperation with the applicable City and Contractor, for exploration and/or salvage. These actions, as well as final mitigation and disposition of the resources, shall be subject to the approval of the applicable Plannina Director.Based on their interest and concern about the discovery of cultural resources and human remains during Project aradina. a Native American Monitor shall be retained to observe some or all aradina activities.Nothing in this mitigation measure precludes the retention of a sinale cross-trained observer who is qualified to monitor for both archaeological and paleontological resources. • Prior to construction,contractors,and Sanitation District staff will receive an archaeological orientation from a professional archaeologist regarding the types of resources that could be uncovered during construction activities and the identification of these resources. The orientation also will cover procedures to follow in the case of any archaeological discovery.

Despite the project's location in an earthquake-prone area, only a portion of the project lies within a liquefaction area(City of Newport Beach, 2006). Mitigation Measure 3.5-2 will ensure that any potential impacts related to liquefaction will be mitigated to less than significant. A geotechnical study was completed for the District 6 Project, and included as Appendix E to this Addendum. A brief summary of the study's findings are provided below. The 2007 PEIR found that geological impacts would be less than significant due to design standards and engineering and construction practices. However, it found that pipelines located in peat bogs could be damaged from collapse of peat mat or fires (refer to page 3-42 of the PEIR). No part of the District 6 Project lies over peat(CGS, 2010; California Division of Mines and Geology, 1976), so there is no impact of the District 6 project on facilities placed in soils susceptible to settlement. The level of impact would not increase from those levels identified in the 2007 PEIR. New infrastructure would be constructed in an area that has a potential landslide risk as part of the District 6 Project; however this would not be a new exposure to landslides because it is in an area that has been previously developed. All design work will be in compliance with laws,regulations, and building codes, while standard construction practices will control soil erosion and loss of topsoil.The level of impact would not increase from those levels identified in the 2007 PEIR. As this is a sewer trunk rehabilitation project,there are no septic tanks or alternative wastewater disposal systems that are part of the District 6 project,therefore there will be no impacts related to soils supporting the use of such systems. Additional Geology and Soils Analysis As required under Mitigation Measure 3.5-2, applicable to the District 6 Project(see Section 1.4.2), soil surveys were completed during project design to determine the liquefaction potential along the pipeline alignment.A gemechnical report completed for the District 6 Project has been included as Appendix E to this Addendum. The report made the following findings: • Fault Ruptures: The Study Area is within a seismically active area,but does not cross known active or potentially active faults.The potential for fault-related ground rupture to impact the Project Area is low to very-low,although there is potential for ground shaking to occur as a result of local or regional fault-based earthquakes.Fault rupture impacts associated with the District 6 Project would be less than significant with implementation of Mitigation Measure 3.5-1,which requires compliance with building codes. • Strong Groundshaking: Peak ground acceleration(PGA)for an event with a 10 percent probability of exceedance in a 50-year exposure period is 0,35g.The mean moment magnitude is 6.64 at a distance of 18.1 km from the Study Area,and the shear wave velocity of the alluvium was assumed to be 270 meters per second.Groundshaking impacts associated with the District 6 Project would be less than significant with implementation of Mitigation Measure 3.5-1,which requires compliance with building codes. • Liquefaction:Potential was found for liquefaction within the southern portion of the Project Area, and potential for liquefaction may exist at depth greater than the soil tests conducted for the report.Liquefaction impacts associated with the District 6 Project would be less than significant with implementation of Mitigation Measure 3.5-2,which requires use of consolidated,engineered backfill in pipeline construction. August 2016 2-31 113054.1 Addendum to the Collection System Improvement Plan PER District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL • Soil Instability-Settlement: Seismic settlement within the Project Area would likely be a result of liquefaction-related settlement and densifrcation of dry cohesionless soils from earthquake shaking.Any potential settlement is estimated to be less than one inch. Settlement impacts associated with the District 6 Project would be less than significant. • Soil Instability—Lateral Spreading:At current groundwater levels,the risk of lateral spreading is low. This risk increases if groundwater levels rise in the future to within about 10 feet of the ground surface.Lateral spreading impacts associated with the District 6 Project would be less than significant • Flooding and Tsunami:Flooding potential for the Project Area is low,and it lies outside the mapped tsunami inundation area. Therefore potential flooding and tsunami hazards can be considered less than significant. Design of the District 6 Project accounted for these findings,and appropriate design choices were made to minimize the geologic and soil hazards for the District 6 Project. Therefore,the level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.7 Greenhouse Gas Emissions The requirement to analyze greenhouse gas(GHG)emissions was added to CEQA after the completion of the 2007 PEIR.A GHG analysis is not required for the project(Concerned Dublin Citizens v. City of Dublin (2013) 214 CalApp.4'" 1301, 1320). Nonetheless, a project-level air quality analysis was completed for the District 6 Project,which included a GHG analysis.The results of this analysis are automatized below, and the complete air quality analysis included as Appendix B of this Addendum. Additional Greenhouse Gas Analysis In 2010(after the completion of the 2007 PEIR),the requirement to analyze greenhouse gas(GHG)impacts was added to the CEQA Guidelines. GHGs cause global climate change through their ability to effectively tap heat within the Earth's atmosphere. GHGs include carbon dioxide(CO2),methane(CH4)and nitrous oxide (N2O). CO2 is the most common GHG, and GHG emissions are generally reported in CO2- equivalents(CO2e).Emissions of GHGs can occur naturally(e.g.,forest fires,decomposition)or as a result of human activities(e.g.,consumption of fossil fuels for energy generation and transportation,heating,and cooking). A comprehensive,project-level analysis of potential GHG emissions and impacts resulting from the District 6 Project was included in the Air Quality and Climate Change Technical Memorandum, included as Appendix B to this Addendum,and results have been summarized here. There are federal, State, and regional/local GHG-related regulations applicable to the District 6 Project. These regulations include the Federal Clean Air Act (CAA) under the U.S. EPA; Assembly Bill 1493, Executive Order 5-3-05,Assembly Bill 32,Executive Order 5-1-07 and Senate Bill 97 under the California Air Resources Board(CARB);and relevant regulations of the South Coast Air Quality Management District (SCAQMD).A summary of the relevant portions of these regulations is provided in Air Quality and Climate Change Technical Memorandum(Appendix B). GHG emissions from the District 6 Project are anticipated to be a result of the operation of construction equipment and on-and off-road vehicle trips. Construction equipment emissions were calculated using horsepower-based composite emissions factors with built-in load factors obtained from the SCAQMD. These emissions factors represent fleet-wide average emission factors within the South Coast Air Basin in 2014.On-road vehicle trip emissions were calculated using CARB's On-Road EMFAC2011 mobile source emissions factors,obtained from the EMFAC2011 model. Results from the modeling and quantification of GHG emissions anticipated from the District 6 Project were compared against interim significance thresholds established by SCAQMD and CARB. The interim August 2016 2-32 1136054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL SCAQMD threshold is 10,000 metric tons of CO2e per year (MTCO2e/yr) for industrial projects (construction impacts amortized over a 30-year period, plus operational impacts). CARB's proposed interim threshold, which has not yet been adopted, is 7,000 MTCO2e/yr for non-transportation GHG emissions.Because the District 6 Project's GHG emissions will almost entirely result from transportation, the SCAQMD thresholds were used to determine the significance of potential GHG impacts from the District 6 Project.As shown in Table 2-4,construction of the District 6 Project is anticipated to create 4.58 MTCO2e/year,well below the SCAQMD interim threshold.These results were used to determine that there would be no GHG impacts from the District 6 Project, as described below. As stated in the air quality discussion above,operation and maintenance activities for this project are anticipated to be consistent with current operation and maintenance of the existing sewer pipeline. Therefore, long-term GHG emissions associated with operation and maintenance activities are not anticipated to increase over current conditions. Table 2.4: Project GHG Emissions and SCAQMD Threshold Source • - Total Project CO2e Emissions During Construction (MTCO2e/Project) 137.27 Emissions Construction GHG Emissions,Amortized over 30 years(MTCO2e/year) 4.58 SCAQMD Interim GHG Threshold for Industrial Projects(MTCO2e/yr) 10,000 Exceed the Threshold (Yes/No)? NO Would the project generate GHG emissions,either directly or indirectly,that may have a significant impact on the environment? Implementation of the Project would generate greenhouse gases through the construction and routine maintenance of the Project. GHG emissions from the Project would specifically arise from the temporary direct sources, such as motor vehicles and construction related diesel equipment Emissions from these sources were estimated using the CaIEEMod model based on default emission factors and land use consumption and generation rates. As shown in Table 24, construction of the District 6 Project would generate 137.27 MTCO2e over the project life,with amortized construction emissions of 4.58 MTCO2e/yr. Operation and maintenance of the District 6 Project is not anticipated to produce substantial GHG emissions beyond the current emissions associated with operation and maintenance of the pipeline, as the project would be operated and maintained in a manner similar to current conditions. The air quality mitigation measures in the 2007 PEIR are designed to reduce fugitive dust pollutants, and would not reduce GHG emissions. As such, the GHG emissions included in Table 2-4 are the anticipated GHG emissions of the District 6 Project with no mitigation measures incorporated. Construction and operation emissions would be below the SCAQMD thresholds of 10,000 MTCO2e, and GHG emissions impacts would be less than significant.No mitigation is required. Would the project conflict with any applicable plan,policy,or regulation adopted for the purpose of reducing the emissions of GHGs? At the state level,AB 32 established the goal of reducing GHG emissions in California to 1990 levels by 2020.The interim SCAQMD screening-level thresholds are designed such that a 90 percent capture rate is achieved, meaning that 90 percent of all development projects would need to incorporate some form of emission reductions in order to achieve the threshold. These rates were established by SCAQMD to be compliant with the AB 32 threshold of reducing GHG emissions to 1990 levels by 2020. The Project's GHG emissions would be below the SCAQMD's screening-level thresholds, and would therefore not conflict with AB 32. Because the Project is compliant with the SCAQMD threshold, and would comply with all regulatory requirements related to GHG emissions, the Project would not conflict August 2016 2-33 113054.1 Addendum to the Collection System Improvement Plan PER District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL with plans, policies or regulations adopted to reduce emissions of greenhouse gases. The impact of the Project would be less than significant and no mitigation is required. 2.1.8 Hazards and Hazardous Materials Hazardous materials are used for corrosion and odor control. The 2007 PEIR identified four hazardous materials that would be used during project construction (refer to page 3-45 of the PEIR): hydrogen peroxide,magnesium hydroxide,ferrous chloride,and sodium hydroxide.For the District 6 project,OCSD intends to use magnesium hydroxide or ferrous chloride to perform odor control by dosing the trunk sewer prior to construction. In the event that an air scrubber is used instead of dosing for odor control,hydrogen peroxide or sodium hydroxide may be used. The pipeline analysis conducted as part of the design for the District 6 project identified cracks,corrosion,and encrustation at joints in the pipeline,indicating a risk of leaks and therefore soil contamination in the project area. Mitigation Measure 3.6-6 will be implemented to provide for safe handling of potentially contaminated soils. Although road closures are not anticipated as part of the District 6 project, construction will occur along a major artery(Newport Blvd.), and near a hospital, increasing the potential to impair implementation of an emergency response or evacuation plan. Mitigation Measures 3.11-1 and 3.11-2, discussed under Traffic will address potential impacts to implementation of emergency response or evacuation plans. Therefore, the level of impact would not increase from those levels identified in the 2007 PEIR. The 2007 PEIR identified Impact 3.6-5 as less-than-significant with mitigation. The District 6 project is located within the Newport Blvd.right-of-way,which has been previously excavated for prior installation of pipelines and other utilities. Therefore, it is not expected that oil wells will be encountered during the District 6 project,and Impact 3.6-5 is not applicable. Although the project is not located within a quarter-mile of an existing or proposed school, and therefore will have no impact related to emitting hazardous emissions or handling hazardous materials substances of waste within a quarter-mile of a school,hazardous emissions and handling of hazardous materials or waste will be addressed through Mitigation Measures 3.6-1 through 3.6-6. The project is also not within a hazardous materials site, per the California Department of Toxic Substances Control's EnviroStar Hazardous Waste and Substances Site List and the Cortese List. The Upper Reach of the project is outside of the John Wayne Airport planning area(Orange County Airport Land Use Commission, 2008). There are no other airstrips within the vicinity of the project.Additionally, the project is not near wildlands.Impacts to these areas are therefore not applicable to the District 6 Project. Additional Hazardous Materials Analysis In compliance with Mitigation Measure 3.6-6, a limited regulatory agency search was performed for the Study Area.The records search included the SWRCB GeoTmcker database and the California Department of Toxic Substances Control(DTSC)EnviroStor database.These lists are a compilation of information on potential and confirmed hazardous wastes and substances sites in California. Results from the records search are provided in Appendix F to this Addendum. Within the project area and immediately adjacent to the District 6 Sewer Trunk were four closed sites: Hughes Aircraft Co.—Solid Prod,Newport Autoworks,City of Newport Beach Corporate Yard,and Ford's Automotive. Each of these sites were leaking underground storage tanks,but cleanup has been completed. Sites of potential concern near, but not within or immediately adjacent to the pipeline include: Newport Health Care Facility(Active—remediation)on Dana Rd.,Raytheon Micro Electronics(Closed)on Superior Ave.,Ralph Irwin Site(Closed)on Old Newport Blvd., Smith and Sons(Closed)and Hartman Enterprises (Inactive—needs evaluation)on Ohms Way,Jim Lee Plumbing(Closed)on Industrial Way,Hoag Memorial Hospital(Inactive—needs evaluation)on Newport Blvd. August2016 2-34 113W54.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL All leaking underground storage tanks within or near the project have been closed, indicating cleanup has been completed.All Sites reported near the project are listed in Appendix A,along with maps showing sites and the approximate location of the District 6 Sewer Trunk.No active sites of concern are anticipated to be encountered during project construction.Therefore,the level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.9 Hydrology and Water Quality Construction activities inherently include risk of stormwater contamination due to erosion/sedimentation during grading and excavation. In accordance with Mitigation Measure 3.7-1 of the PEIR, projects with surface disturbances of 1 acre or more require a NPDES General Permit for Discharges of Stone Water Associated with Construction Activities and a Storm Water Pollution Prevention Plan(SWPPP).The total disturbed area of the District 6 project would exceed 1 acre in size; a SWPPP will be developed and implemented, and all required permits acquired. The SWPPP would include erosion and sedimentation control best management practices (BMPs), along with BMPs to prevent or minimize pollution from the construction site into surface waters. Therefore, the level of impact would not increase from those levels identified in the 2007 PEIR. The 2007 PEIR found potential impacts to biological resources for project activities within jurisdictional areas.These impacts would require Mitigation Measure 3.7-2.However,the District 6 project is not within waters of the U.S.,nor within jurisdictional areas,therefore this potential impact and its mitigation measure is not applicable to the project. Any excavation activities may encounter groundwater, thereby requiring dewatering, and subsequently leading to potential impacts to surface water quality.Although dewatering will be discharged to the sanitary sewer system under this project, to be conservative, and for consistency with the 2007 PEIR, Mitigation Measure 3.7-3 will be implemented to reduce impacts to less-than-significant.This measure is included as a contingency in the unanticipated event that dewatered flows cannot be discharged to the sewer. Though the project may encounter groundwater during excavation activities, it will not deplete groundwater resources,and impacts to groundwater supply volumes or the aquifer volume are not applicable. Impacts to drainage patterns that would result in erosion, siltation, or flooding are also not applicable because the project will not alter the overall drainage patterns of the area,and all roadway drainages within Newport Blvd.will be restored to pre-construction conditions following installation of the pipeline.Further, the project will not create or contribute to runoff water that exceeds the capacity of the drainage system because project facilities would primarily exist underground within current impervious areas when completed. The project will not create additional impervious surfaces from current conditions that would lead to additional runoff. Nor will it contribute a substantial additional source of polluted runoff because project activities will not contribute to runoff water,and dewatering will be discharged to the sanitary sewer for treatment. The level of impact would not increase from those levels identified in the 2007 PEIR. The project is not within the 100-year flood hazard area (City of Newport Beach, 2008), therefore no structures or housing will be placed within the flood hazard zone.Further,the project will not redirect flows within the I00-year flood zone,No dams or levees will be impacted by the project,therefore there will be no dam or levee failure impacts. Finally, the 2007 PEIR found that the project will not have any impacts related to seiche,tsunami,or mudflow,and no changes made to the project since development of the 2007 PEIR would lead to increased potential for impacts related to seiche,tsunami,or mudflow. 2.1.10 Land Use and Planning The 2007 PEIR has identified sensitive receptors near the project area, including a hospital. Mitigation Measures 3.8-1 through 3.8-3 are required to address the needs of these receptors during temporary impacts of construction. Although few businesses will be affected by the District 6 project because of its location August 2016 2-35 113054.1 Addendum to the Collection System Improvement Plan PER District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL along Newport Blvd.,Mitigation Measure 3.84 is required to ensure that there will be no disruptions from construction activities. The level of impact would not increase from those levels identified in the 2007 PEER. The project is outside the bounds of Orange Coastal/Central Natural Community Conservation Plan and will not conflict with an existing habitat conservation plan or natural community conservation plan. The District 6 project rehabilitates an existing sewer trunk,which is primarily underground,therefore the project will not physically divide an established community. The level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.11 Mineral Resources The District 6 project will occur entirely on previously developed land and therefore would have no impact on mineral resources.The level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.12 Noise The 2007 PEIR indicates that as long as construction occurs only during the time limits set by the City of Newport Beach(7:00 am— 6:30 pm) and the City of Costa Mesa (7:00 am— 11:00 pm) during the week, the project will be in compliance with noise standards. Section 1.4.1 lists this requirement as an environmental commitment from the 2007 PEIR that applies to the District 6 project.Construction activities for the District 6 Project have not changed such that substantial increases in potential noise levels from those evaluated for the 2007 PEIR would occur. In addition,Mitigation Measure 3.9-1 will ensure that all noise impacts are reduced to less than significant, including impacts to ambient noise levels, and noise levels affecting people residing or working in project areas that we also within an airport planning area(in this case the John Wayne Airport). Implementation of this mitigation measure could include temporary noise reduction measures(e.g.,sound blankets or sound walls),placement of stationary equipment in areas where noise would naturally be buffered (e.g., inside jacking pits), limiting times of day of use of particularly disturbing activities(e.g.,pile driving), and noise monitoring at the closest sensitive receptors. There me no noise impacts to people residing or working in the project area that is within the vicinity of a private airstrip because there is no private airstrip new the project area; therefore this impact is not applicable to the District 6 project. There may be some areas where construction activities are within the 25-feet vibration area for structures, though only lower vibration equipment will be used for this project. Any potential impacts from vibration will be mitigated by Mitigation Measure 3.9-2. Figure 2-2 shows the 25-foot notification buffer where structures will be notified. Figures 2-3 through 2-5 provide additional detail in segments of the District 6 Project where structures lie within the notification area. Therefore,the level of impact would not increase from those levels identified in the 2007 PEIR. The Upper Reach of the project is outside of the John Wayne Airport planning area(Orange County Airport Land Use Commission,2008).There are no other airstrips within the vicinity of the project.Therefore,the District 6 Project would result in no noise impacts related to a public use airport or private airstrip. August 2016 2-36 1136054.1 L A Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL Figure 2.3: Vibration Notification Area for MH130-MH140 f Tr t .. i August 2016 2.38 1136054.1 :t a 1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL Figure 2.5: Vibration Notification Area for MH190-MH210 Ct�t h' v .i 2.1.13 Population and Housing There would be no significant impacts to population or housing from the District 6 project because the project will allow the area to accommodate planned growth that would occur with or without the District 6 Project.Further,the District 6 project will not displace housing or people because it accommodates planned growth patterns and does not affect existing housing and involves and underground sewer line. Therefore, the level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.14 Public Services The Project calls for the rehabilitation or replacement of an existing,underground trunk sewer line. The Project will not require the provision of new or physically altered governmental facilities which, in and of themselves, could cause significant environmental impacts. All of the identified traffic impacts from the 2007 PEIR would also be incurred by the District 6 project, and require mitigation.Mitigation Measure 3.11-1 will be implemented to reduce the traffic impacts from temporary construction activities that could affect emergency responders, local service providers, and August 2016 240 113W54.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL schools. Provision of the project's Traffic Control Plan, required by Mitigation Measure 3.12-1, to emergency services departments prior to construction will allow first responders to be aware of and plan around the potential traffic impacts,while 72-hour notice of construction to local service providers at each pipeline segment will similarly allow them to plan around the traffic impacts. The level of impact would not increase from those levels identified in the 2007 PEIR. Given the close proximity of a hospital to the construction area, there could be an impact on access to emergency medical facilities. Mitigation Measure 3.11-2 will allow for at least one access road to the hospital at all times, and will be particularly important during pipeline realignment, which will require trenching in the shoulder of a major artery(Newport Blvd.). Trenches me an integral part of the District 6 project, both for the new pipeline alignment and for the pipe bursting activities, so there is potential for safety impacts from trenches,which will require Mitigation Measures 3.11-3a through 3.11-3c to reduce to less than significant.These mitigation measures will ensure safe closing of trenches,secured open trenches to avoid accidents, covering of trenches as appropriate, establishment of other safety measures, and restoration of disturbed areas following completion of construction.The level of impact would not increase from those levels identified in the 2007 PEIR. Security will be important to protect equipment during storage and site staging from vandalism, which could occur to unsecured equipment that must remain at or near the project site because construction will take multiple days to complete. Mitigation Measure 3.11-4 will secure equipment and storage areas to protect from potential vandalism.The level of impact would not increase from those levels identified in the 2007 PEIR. Waste will be produced by the construction activities associated with the District 6 project,which requires proper disposal. Mitigation Measures 3.11-5a and 3.11-5b will ensure proper disposal and mitigate the impacts to public services from improper disposal of waste. The level of impact would not increase from those levels identified in the 2007 PEIR. Preliminary design plans indicate nearby existing utilities along the pipeline route within the existing right- of-way in which the pipeline will be constructed.Utilities along the pipeline route should be identified and Mitigation Measures 3.11-6a through 3.11-6c implemented to reduce impacts associated with disruptions to existing utilities.The level of impact would not increase from those levels identified in the 2007 PEIR. It is unlikely that the District 6 project will affect the compatibility of existing and future projects because it is designed to address planned needs,but to ensure that it will not,OCSD will coordinate with the Orange County Resources and Development Management Department and otherjurisdictions as required through Mitigation Measure 3.11-7. The level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.15 Recreation The District 6 project is not located near recreation facilities, and as a sewer trunk relief project, does not include recreation facilities.Therefore,it will not have an impact on the recreational environment or impact the environment through recreational facilities. The level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.16 Transportation and Traffic As identified in the Program EIR, the project will have traffic impacts because construction will occur within the roadway and the paved shoulder. Although the District 6 project will have transportation and traffic impacts, these impacts will be to a lesser degree than those of the project in the PEIR because less replacement activities are required than the project evaluated in the PEER.While many of these impacts can and will be mitigated to less-than-significant,lane closures(Impact 3.12-2)are significant and unavoidable August 2016 241 1136054.1 Addendum to the Collection System Improvement Plan PER District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL as identified in the 2007 PEIR, as they are a necessary temporary, construction-related impact. Traffic impacts and road closures were considered when selecting the District 6 Project, which avoids open trenching for the Newport Blvd. crossing. Despite the unavoidable nature of the lane closures,Mitigation Measures 3.12-2a through 3.12-2f will be implemented to reduce impacts from lane closures. These mitigation measures include staging equipment within closed lanes or outside of the roadway, providing signage informing the public of the project prior to commencement of construction,the use of traffic cones and/or guards, consideration of traffic impacts in project selection, minimizing lane closures during peak traffic hours,delineating suitable detours,and coordinating with local jurisdictions and Caltrans.Therefore, the level of impact would not increase from those levels identified in the 2007 PEIR. Traffic impacts that can be mitigated to less-than-significant include construction activities occurring within city streets (Impact 3.12-I) and impacts to emergency access. Impact 13.2-1 will be mitigated to less than significance because most construction activities will occur in the public right-of-way, will involve lane closures and related traffic impacts,and all phases will involve some degree of excavation.Mitigation can be achieved with traffic controls(from the Traffic Control Plan);restoration of roads following completion of project; coordination with Caltrans and other agencies with jurisdiction over roadway rights-of-way as appropriate; consultation with emergency service providers regarding access; consultation with Orange County Transportation Authority regarding impacts to bus route and station accessibility; rerouting of construction traffic(mainly trucks)to avoid sensitive receptors including a nearby hospital, school,places of worship, and post office; and public input during planning phase. Mitigation Measure 3.12-lk is not applicable to the District 6 project because no construction will occur in the railway right-of-way. Emergency access concerns will be mitigated as described here and under Public Services through Mitigation Measures 3.12-1 g, 3.11-1,and 3.11-2. The level of impact would not increase from those levels identified in the 2007 PEIR. A less-than-significant impact will occur on parking capacity because curbside parking may be limited during construction,however,this is a non-significant amount of curbside parking,and will only be short- term. There will be no long-term impacts on parking from the District 6 project, which will not affect parking facilities or change land use such that parking impacts occur.There will be no impacts on air traffic patterns from the District 6 project because it does not affect nearby airports or air traffic. The project will also not include any hazardous design features as part of its compliance with local ordinances and construction standards. Finally, the project will not impact or conflict with adopted plans, policies or programs supporting alternative transportation because the project will not affect transportation beyond short-term lane closures. The level of impact would not increase from those levels identified in the 2007 PEIR. Additional Transportation and Traffic Analysis In accordance with the findings of the Environmental Analysis for transportation and traffic(Table 2-19), above, Table 3-8 of the 2007 PEIR should be revised to accurately reflect the transit routes, cross streets, and references for the District 6 project. Appendix G includes the original Table 3-8 as presented in the 2007 PEIR,edited only to reflect changes related to the District 6 project,with additions in underline, and deletions in stnkat4augh.A summary of these changes is presented here: • The End Date for the District 6 Project has been changed from 2010 to 2017 • Newport Beach Blvd.was changed from two lanes to six and updated to Transit Route 71 • Two additional streets were added under the City of Newport Beach for the District 6 Project: o Newport Beach Blvd.at Hospital Rd.was added.At this cross street Newport Beach Blvd. is 6 lanes,classified as arterial,and uses signals for traffic control August 2016 242 113054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL o Superior Ave. at 16't Street was added. This is a four lane road with signals for traffic control. • The URL for the OCTA bus route was updated to fix a broken link. 2.1.17 Utilities and Service Systems The District 6 project will address previously identified present and future needs and will therefore not exceed any unanticipated wastewater treatment requirements. It is also part of the Sanitation District Strategic Plan, and will therefore not result in construction or expansion of water or wastewater treatment facilities above what is included in the Strategic Plan. Inclusion of the project in the Strategic Plan also means that there will not be an impact related to wastewater treatment capacity because the capacity expansion resulting from this project is designed to address previously identified and planned for needs. The level of impact would not increase from those levels identified in the 2007 PEIR. The District 6 project will not construct storm drains,nor will it create new runoff or redirect flow to storm drains,therefore there will be no expansion of the storm drain system related to the project. The level of impact would not increase from those levels identified in the 2007 PEIR. The project will not require the provision of new water supplies—existing supplies me sufficient to meet the project needs (construction-related water use) and will not result in impacts to water entitlements or resources.All solid waste will be disposed of in accordance with applicable federal,state,and local statutes and regulations, as part of normal project activities, therefore no impacts are associated with compliance with federal, state, and local statues related to solid waste. The level of impact would not increase from those levels identified in the 2007 PEIR. For these reasons,there are no impacts associated with the Utilities and Service Systems,with the exception of sufficient permitted capacity at the landfill to accommodate the project's solid waste disposal needs.The impacts to landfill capacity are less-than-significant because of the small size of the project and the anticipated amount of solid waste to be produced.The level of impact would not increase from those levels identified in the 2007 PEIR. 2.1.18 Mandatory Findings of Significance There are short-term construction related impacts associated with air quality,noise,and transportation that have been found to be significant and unavoidable in the 2007 PEIR.Mitigation measures applicable to the District 6 Project(refer to Section 1.4.2 of this Addendum)will reduce the cumulative impacts for all other resource areas to less-than-significant. The level of impact would not increase from those levels identified in the 2007 PEIR. August 2016 243 1136054.1 Addendum to the Collection System Improvement Plan PEIR District 6 Sewer Trunk Relief Chapter 2 Environmental Checklist FINAL 2.2 Environmental Determination CEQA Guidelines §15164 dictates that an addendum to an EIR shall be prepared if some changes or additions are necessary but none of the conditions described in §15162 calling for preparation of a subsequent EIR have occurred. An addendum need not be circulated for public review, but the decision- making body shall consider the addendum with the final EIR(including an explanation of the decision not to prepare a subsequent EIR)prior to making a decision on the project(CEQA Guidelines §15164). Based upon the evidence in light of the whole record documented in the Chapter 2,Environmental Checklist analysis, cited incorporations, and attachments,I find that the Project: ❑ Has NOT been previously analyzed as part of an earlier CEQA document(which either mitigated the project or adopted impacts pursuant to findings)adopted/certified pursuant to CEQA Guidelines. Preparation of adequate CEQA environmental documentation is required. ❑ Has previously been analyzed as part of an earlier CEQA document(which either mitigated the project or adopted impacts pursuant to findings)adopted/certified pursuant to CEQA Guidelines. The proposed project is a component of the whole action analyzed in the previously adopted/certified CEQA document. No additional CEQA documentation is required. ® Has previously been analyzed as part of an earlier CEQA document(which either mitigated the project or adopted impacts pursuant to findings)adopted/certified pursuant to CEQA Guidelines. Minor additions and/or clarifications are needed to make the previous documentation adequate to cover the project which are documented in this addendum to the earlier CEQA document (CEQA §15164).No additional CEQA documentation is required. ❑ Has previously been analyzed as part of an earlier CEQA document(which either mitigated the project or adopted impacts pursuant to findings)adopted/certified pursuant to State and County CEQA Guidelines.

Less Than Significant With Mitigation. Mitigation Measure 3.3.1: Evaluation of impacts to special-status plants, birds, mammals,and amphibians and reptiles will occur at the project level. Specifically,all areas of natural habitat within the footprint of proposed construction activities with potential to support special-status biological resources will be surveyed according to standard protocol.Where special-status biological resources are identified within the project footprint,appropriate avoidance, minimization,and mitigation measures will be implements.Depending on the special-status biological resources present,measures could include the following: Where rare plants are identified within the project footprint,the following avoidance,minimization,and mitigation measures will be implemented: • Project design will be evaluated to determine if an exclusionary zone can be established around rare plant populations;where feasible,this will be implemented,and construction activities will be relocated or modified to avoid impact. • If rare plant populations cannot be avoided,appropriate salvage of plant propagules will be implemented,and suitable habitats for transplanting or re- establishing population will be identified and implemented. • Mitigation will include an analysis of suitability of alternative locations and identification of suitable propagation techniques. • Procurement of conservation easements will be implemented for alternative suitable habitats if the habitats are not already secured with conservation status. Where special-status nesting birds are identified within the project footprint,the following avoidance,minimization,and mitigation measures will be implemented: • Project design will be evaluated to determine if a 500-foot minimum exclusionary zone can be established around active bird nests;where feasible,this will be implemented,and construction activities will be relocated or modified to avoid impact. • If nesting birds or active nest sites cannot be avoided,construction will be timed to avoid the active nesting season(February to August), and construction activities will not commence in the vicinity of nests until young have Fledged. Where special-status mammals or bat roosts are identified within the project footprint,the following avoidance, minimization,and mitigation measures will be implemented: • Project design will be evaluated to determine if a 500-foot minimum exclusionary zone can be established around active bat roosts;where feasible,this will be implemented,and construction activities will be relocated or modified to avoid impact. • Project design will be evaluated to determined direct impacts to habitats supporting small mammals can be avoided with an exclusionary zone;where feasible,this will be implemented,and construction activities will be relocated or modified to avoid impact. • Where avoidance is not feasible,trapping or hazing of special-status mammals to remove them from the project site will be implemented,and individuals will be relocated to suitable habitat nearby;temporary fencing will be installed to prohibit species from returning to the construction zone. • If construction adjacent to bat roosts cannot be avoided,construction will be timed to avoid the parturition period(February to August),and construction activities will not commence in the vicinity of maternity roosts until young are weaned.

Less Than Significant With Mitigation. Mitigation Measure 3.3-2: To avoid impacts to aquatic fisheries, best management practices will be implemented to avoid contaminant runoff from construction practices.This will include the following: • Equipment will not be operated in areas of ponded or flowing water. Stationary equipment such as motors, pumps,generators,and welders will be located a minimum of 200 feet outside aquatic and wetland habitats;construction staging areas,stockpiling,and equipment storage will be located a minimum of 200 feet outside aquatic and wetland habitats. • Construction vehicles and equipment will be checked periodically to ensure that proper working conditions with no potential for fugitive emissions of oil and other hazardous products exists.Refueling or lubrication of vehicles and cleaning of equipment,or other activities that involve open use of fuels,lubricants, or solvents,will occur in upland locations at least 200 feet away from aquatic or wetland habitats. • Temporary sediment-retention structures, hay bales,or silt fencing will be placed downstream of construction areas; sediment-retention devices will prevent sediment-laden water from draining offsite;sediment-retention devices structures will be maintained and repaired after flood events.

CDFG Cultural Resources Impact 3.4-1: Project activities could affect known,significant archaeological, paleontological,and historical resources. Less Than Significant With Mitigation. Mitigation Measure 3.4.1: During preliminary design a Registered Professional Archaeologist(RPA)will complete a literature review using the archives of the South Central Coastal Information Center of the California Historical Resources Information System(CHRIS),located at California State University Fullerton,and other sources as needed to identify previous cultural resources studies and previously recorded archaeological sites within close proximity to the project alignment.The literature search will also include a search of the Sacred Lands Database maintained by the California Native American Heritage Commission (NAHC). Using the results of the literature review in part,the archaeologist will develop a cultural resources sensitivity map for the project alignment,followed by a determination of specific areas of the project that may require preconstmction survey,subsurface testing,or construction monitoring. Cultural resources identified as a result of the literature review,field survey,testing,or construction monitoring will be evaluated by a Registered Professional Archaeologist to determine whether they meet the criteria for designation as a historical resource(14 CCR§4850, PRC§21084.1, 14 CCR§15064.5(3))or a"unique archeological resource"as defined in PRC§21083.2.

Mitigation Measure 3.12-2e: Public streets generally will be kept operational during construction,particularly in the morning and evening peak hours of traffic. Lane closures will be minimized during peak traffic hours. Mitigation Measure 3.12-2f: Where mad closures are necessary for construction of sewer improvement projects,signage will be posted informing motorists of road closures and delineating suitable detours, both prior to and during the duration of construction activities. Prior to initiating a road closure,coordination with local jurisdictions, including Caltrans,will occur.

The sewer ultimately discharges into sewer along Pacific Coast Highway,where the flow is eventually conveyed to the Bitter Point Pump Station. The District 6 Trunk Sewer Relief Proj ect was identified in the 2006 Strategic Plan Update as requiring updates.Based on current flow projections and hydraulic modeling,this project is needed to reduce the potential for surcharging and sewer spills due to projected increase in flow from planned developments and growth. Investigations also revealed that segments initially identified as not being up-sized,require rehabilitation and maintenance access improvements as well.Approximately two-thirds of a mile will be improved as part of this project. The sewer will be rehabilitated using a variety of methods including pipe bursting, open-cut pipe replacement/realignment,and cured-in-place relining.Several maintenance access points will also be reconstructed or relocated.Access improvements involving surface modifications will be done to improve safety and reduce risk when accessing the pipe for maintenance. 1.2 Purpose and Scope The California Environmental Quality Act (CEQA) requires public agencies to analyze and consider the environmental consequences of their decisions to approve development projects over which they exercise discretion. As lead agency, the Orange County Sanitation District (OCSD) prepared a Program Environmental Impact Report (PEIR)for the OCSD Collection System Improvement Plan in compliance with the California Environmental Quality Act (CEQA) (Public Resources Code, section 21000 et seq.) and the State CEQA Guidelines (California Code of Regulations,Section 15000 et seq.,as amended).The District 6 Project was one of 19 collection system improvement projects analyzed in the PEIR. The Project is therefore a subsequent activity within the scope of the PEIR(CEQA Guidelines§15168). Subsequent activities in a PEIR must be examined in light of the PEIR to determine whether an additional environmental document must be prepared(CEQA Guidelines§15168(c)). During the design phase of the District 6 Project, minor changes to the project description were identified. An Addendum to a previously certified EIR is appropriate if some changes,additions,or clarifications are necessary,but no substantial new information or substantial changes to the project or circumstances would require major revisions to the previous EIR(CEQA Guidelines§15162). In reviewing the Project details,OCSD staff identified two topics that merit further evaluation:(1)short-term,project- specific air quality impacts;and(2)greenhouse gas(GHG)emissions impacts.After reviewing the facts and analyzing l March 2015 the circumstances,OCSD staff has determined that none of the circumstances described in CEQA Guidelines§15162 have occurred as related to air quality and GHGs. 2.0 AIR QUALITY The OCSD Collection System Improvement Plan PEIR described the existing air quality regarding the following regulated pollutants:ozone(03),carbon monoxide(CO),suspended particulate matter(PMlo),nitrogen oxides(NOx), sulfur dioxide(SO2),lead,and reactive organic gases(ROG).The project site is located in the Orange County portion of the South Coast Air Basin (SCAB). Table 2-1 shows the pollutants and associated attainment status for SCAB. Orange County is designated as a federal and state non-attainment area for 03,and PM2.5,maintenance for CO,and an attainment area for SOt,NOt,PMho and lead. 2.1 Regulatory Setting The South Coast Air Quality Management District(SCAQMD)is the regional agency responsible for the regulation and enforcement of Federal, State, and local air pollution control regulations in the SCAB. The SCAQMD has the responsibility of ensuring that Federal and State ambient air quality standards are achieved,maintained,and enforced in the SCAB. SCAQMD rules and regulations require that any equipment that emits or controls air contaminants be permitted prior to construction,installation,or operation(Permit to Construct or Permit to Operate).The SCAQMD also has visible emissions, nuisance, and fugitive dust regulations which are applicable to the Project during construction activities. These specific regulations include SCAQMD Rule 401 (Visible Emissions);SCAQMD Rule 402 (Nuisance); and SCAQMD Rule 403 (Fugitive Dust).The intent of these rules is to limit the amount of visible emissions and fugitive dust generated from emission sources and to ensure emitted pollutants do not cause a public nuisance. SCAQMD Rule 403 provides control measures to reduce overall fugitive dust emissions from construction activities. Based on the description of the construction activities for the Project, the amount of soil to be excavated, and the acreage of the disturbed areas,the Project does not classify as a`large operation."However,to minimize fugitive dust emissions,feasible fugitive dust control measures as stated in the applicable rules would be implemented as Applicant Proposed Measures (APMs) to reduce potential impacts to off-site receptors (SCAQMD, 2009a). In addition, Mitigation Measure 3.2-2 in the PEIR also addresses fugitive dust emissions. 2.2 Methodology Criteria pollutants and GHG emissions associated with the short term operation of off-road construction equipment, on-road mobile equipment,and fugitive dust dispersion,were quantified using the latest California Emission Estimator Model (CalEEMod)Version 2013.2.2. CaIEEMod applies the latest approved emission factors,methodologies, and latest survey data when tabulating results. The model inputs were tailored to reflect Project/site specific data for a more accurate analysis.The model was run to produce both the daily max and annual average for criteria pollutants, as well as total annual GHG emissions. 2.3 Significance of Impacts Air quality impacts during construction of the Project are presented in Table 2-1 below. Peak daily construction emissions are summarized and are also compared to the established SCAQMD regional mass daily emission thresholds and localized significance thresholds(LSTs)for construction. 2 March 2015 DailyTable 2-1: Peak Criteria Pollutants, lb/day ROG CO NOX SOX PM10 PM2.5 Regional Impact Evaluation Total Daily Emissions 6.53 41.28 58.29 0.06 15.28 9.45 Regional Thresholds 75 550 100 150 150 55 Exceed Regional Thresholds(Yes/No)? No No No No No No Localized Impact Evaluation Total Daily Offsite Emission 0 0 0 0 0.9 0.047 Localized Significance Thresholds - 647 92 - 4 3 Exceed LST(Yes/No)? No No No No No No 2.4 Application of CEQA Thresholds Would the project conflict with or obstruct implementation ofthe applicable air quality plan? An emissions in the SCAB are regulated by the SCAQMD. Pursuant to the federal Clean Air Act (CAA), the SCAQMD is required to reduce emissions of criteria pollutants for which the SCAB is in non-attainment. Strategies to achieve these emission reductions are developed in SCAQMD's Air Quality Management Plan(AQMP) for the region. Chapter 3 of the AQMP states,"future emissions forecasts are based on demographic and economic growth projections provided by the Southern California Association of Governments(SCAG)." The Project will not conflict with or obstruct implementation of any applicable air quality plans or regulations. The regions currently exceeds standards for ozone and PM2.5,the most significant sources of these pollutants are vehicle and other mobile source emissions.No new impacts associated with the implementation of an air quality plan would occur. Would the project violate any air quality standard or contribute.substantially to an existing or projected air quality violation? The South Coast region is currently in non-attainment with air quality standards for ozone and PM2.5.The Project is not expected to result in significantly increased air emissions.Based on this air quality analysis,potential emissions from truck traffic associated with this project would represent insignificant sources of pollutants contributing to the overall PM,,emissions.Nonetheless,because the South Coast Air Basin is a nonattainment area for ozone and PM2s, applicable air quality mitigation measures included in the PEIR should be employed to minimize particulate emissions during rehabilitation operations.No new impacts associated with the violation of air quality standards would occur. Would the project result in a cumulatively considerable net increase of any criteria pollutant for which the project region is non-affainment under an applicable federal or state ambient air quality standard(including releasing emissions,which exceed quantitative thresholds for ozone precursors)? In evaluating the activities described in the certified PEIR,OCSD had concluded that short-term cumulative impacts related 0 air quality would remain significant after mitigation. When combined with construction of the reasonably foreseeable future projects,construction emissions are anticipated to exceed significance thresholds for NO,.Because air emissions typically are considered on a regional basis,any project being constructed in the general vicinity of the proposed collection system improvement projects during the same construction timeframc likely would contribute to potentially significant cumulative air quality impacts.However,Mitigation Measures from the PEIR applicable to air quality will be incorporated into the Project. No new impacts associated with a cumulative net increase of criteria pollutants would occur. 3 March 2015 Would the project expose sensitive receptors to substantial pollutant concentrations? Sensitive receptors in the Project area include a library, park three places of worship, a hospital, senior living community, and a school.As stated in the PEIR,the temporary increase in emissions of criteria air pollutants during construction would not be expected to exceed SCAQMD-established air quality thresholds for the Project.Emissions associated with operational activities would be minimal and are not anticipated to result in long-term operational impacts that conflict with SCAQMD-established air quality standards. Therefore, the Project would not have a significant impact to sensitive receptors during construction or operation. Would the project create objectionable odors affecting a substantial number ofpeople? The Project would be expected to create some objectionable odors as a result of modification of the existing sewer lines.Currently,OCSD investigates and tracks all odor complaints,performing cleaning and/or repairs as appropriate, and would continue this practice. As part of its operational activity, OCSD injects sodium hydroxide, hydrogen peroxide, ferrous chloride, and magnesium hydroxide at various locations in the collection system to control odor. Construction contractors are required to follow a site-specific odor control plan to minimize odors during rehabilitation activities. Odor control could include monitoring, ventilating, chemical application, material containment limiting atmospheric exposure,and activity staging to minimize odor impacts. Therefore,impacts associated with the creation of objectionable odors affecting a substantial number of people would be considered less than significant. 3.0 GREENHOUSE GAS EMISSIONS The certified PEIR did not contain a greenhouse gas(GHG)emissions analysis,as it was not industry practice in 2007 to routinely perform such an analysis.Since that time,however,analysis of GHG's is now required and new checklist questions were approved for inclusion in the CEQA Guidelines as of March 18,2010.Therefore,GHG emissions are now considered in the environmental analysis for the Project.This analysis is undertaken to determine if the Project would result in adverse impacts in relation to GHG emissions. Global climate change refers to changes in average climatic conditions on Earth as a whole, including temperature, wind patterns,precipitation and storms.Global temperatures are moderated by naturally occurring atmospheric gases, including water vapor, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N20). These gases allow solar radiation(sunlight)into the Earth's atmosphere,but prevent radiative heat from escaping,thus warming the Earth's atmosphere. Global climate change attributable to the emission of GHGs(mainly CO2,CH4 and N20)generated by human activity is currently one of the most important and widely debated scientific,economic and political issues in the United States. Historical records indicate that global climate changes have occurred in the past due to natural phenomena(such as during previous ice ages). Some data indicate that the current global conditions differ from past climate changes in rate and magnitude.These data have led political leaders to take actions designed to reduce GHG emissions generated by human activity. Carbon dioxide is the most abundant GHG. GHGs are the result of both natural and human activity. Forest fires, decomposition, industrial processes, landfills, and consumption of fossil fuels for power generation, transportation, heating, and cooking are the primary sources of GHG emissions. According to the California Energy Commission (CEC), emissions from fossil fuel consumption represent approximately 81 percent of GHG emissions and transportation creates 41 percent of GHG emissions in California. The scientific understanding of the fundamental processes responsible for global climate change has improved over the past decade, and predictive capabilities are advancing. However, there remain significant uncertainties, for example,in predictions of local effects of climate change,occurrence of extreme weather events,effects of aerosols, changes in clouds,shifts in the intensity and distribution of precipitation,and changes in oceanic circulation. Due to the complexity of the Earth's climate system,the uncertainty surrounding climate change may never be completely eliminated. Because of these uncertainties, there continues to be significant debate with respect to the appropriate actions to limit and/or respond to climate change. In addition, it is impossible to link a single development project with future specific climate change impacts. 4 March 2015 3.1 Regulatory Setting 3.1.1 FEDERAL.PLANS,POLICIES,REGULATIONS,AND LAWS The U.S. Environmental Protection Agency(EPA) is the Federal agency responsible for implementing the Federal Clean Air Act(CAA).The Supreme Court of the United States ruled on April 2,2007 that CO2 is an air pollutant as defined under the CAA,and that EPA has the authority to regulate emissions of GHGs.However,there are no Federal regulations or policies regarding GHG emissions that are directly applicable to the Project or that require additional analysis for compliance with the regulations listed below. 3.1.2 STATE PLANS,POLICIES,REGULATIONS,AND LAWS The California Air Resources Board (CARB) is the agency responsible for coordination and oversight of state and local air pollution control programs.Various statewide and local initiatives to reduce the state's contribution to GHG emissions have raised awareness that, even though the various contributors to, and consequences of, global climate change are not yet fully understood,global climate change is under way,and there is a real potential for severe,adverse environmental,social,and economic effects in the long term. Assembly Bill 1493 In 2002,then-Governor Gray Davis signed AB 1493,which required that ARB develop and adopt,by January 1,2005, regulations that achieve `the maximum feasible reduction of GHGs emitted by passenger vehicles and light-duty trucks and other vehicles determined by ARB to be vehicles whose primary use is noncommercial personal transportation in the state." To meet the requirements of AB 1493, in 2004 ARB approved amendments to the California Code of Regulations(CCR)adding GHG emissions standards to California's existing standards for motor vehicle emissions.These amendments require automobile manufacturers to meet fleet-average GHG emissions limits for all passenger cars, light-duty trucks within various weight criteria, and medium-duty passenger vehicle weight classes (i.e., any medium-duty vehicle with a gross vehicle weight (GV W) rating less than 10,000 pounds that is designed primarily for the transportation of persons), begaining with the 2009 model year. For passenger cars and light-duty trucks with a loaded vehicle weight(LV W)of 3,750 pounds or less,the GHG emission limits for the 2016 model year are approximately 37 percent lower than the limits for the first year of the regulations, the 2009 model year. For light-duty trucks with LV W of 3,751 pounds to GV W of 8,500 pounds, as well as medium-duty passenger vehicles, GHG emissions will be reduced approximately 24 percent between 2009 and 2016. On January 24, 2011, the U.S.Department of Transportation(DOT),the EPA and the state of California announced a single fimeframe for proposing fuel economy and greenhouse gas standards for model year 2017-2025 cars and light-duty trucks. The standards require these vehicles to meet an estimated combined average emissions level of 250 grams of carbon dioxide per mile in model year 2016,which is equivalent to 35.5 miles per gallon. Executive Order 5-3-05 In 2005, in recognition of California's vulnerability to the effects of climate change, Governor Schwarzenegger established Executive Order 5-3-05,which sets forth a series of target dates by which statewide emission of GHGs would be progressively reduced,as follows:by 2010,reduce GHG emissions to 2000 levels;by 2020,reduce GHG emissions to 1990 levels;and by 2050,reduce GHG emissions to 80 percent below 1990 levels. Assembly Bill 32 In September 2006,Governor Arnold Schwarzenegger signed AB 32,the California Global Warming Solutions Act of 2006.AB 32 establishes regulatory,reporting,and market mechanisms to achieve quantifiable reductions in GHG emissions and a cap on statewide GHG emissions.AB 32 requires that statewide GHG emissions be reduced to 1990 levels by 2020. In December 2007,ARB approved the 2020 emission limit(1990 level) of 427 million metric tons (MMT) COse. The goal requires that California reduce CO2e emissions by 169 million metric tons (MMT), or approximately 30%,from the state's projected 2020 emissions level of 596 MMT of CO2e under a business-as-usual scenario. 5 March 2015 Executive Order S-1-07 Executive Order S-1-07,which was signed by Governor Schwarzenegger in 2007,proclaims that the transportation sector is the main source of GHG emissions in California,at over 40 percent of statewide emissions. It establishes a goal that the carbon intensity of transportation fuels sold in California should be reduced by a minimum of 10 percent by 2020.This order also directed ARB to determine if this Low Carbon Fuel Standard could be adopted as a discrete, early-action measure after meeting the mandates in AB 32.ARB adopted the Low Carbon Fuel Standard on April 23, 2009. Senate Bill 97 SB 97, signed August 2007, acknowledges that climate change is a prominent environmental issue that requires analysis under CEQA.This bill directs the California Office of Planning and Research(OPR)to prepare,develop,and transmit to the Resources Agency guidelines for the feasible mitigation of GHG emissions or the effects of GHG emissions,as required by CEQA by July 1,2009.The California Natural Resources Agency is required to certify or adopt those guidelines by January 1, 2010. On April 13, 2009, the California Office of Planning and Research submitted to the Secretary for Natural Resources its proposed amendments to the state CEQA Guidelines for GHG emissions,as required by SB 97.On December 30,2009,the Natural Resources Agency adopted the proposed CEQA Guidelines amendments,as required by SB 97.The amendments became effective March 18,2010. 3.L3 REGIONAL AND LOCAL PLANS,POLICIES,REGULATIONS,AND LAWS The SCAQMD monitors an quality within the project area and SCAB,which includes Orange County and portions of Los Angeles,Riverside,and San Bernardino counties. SCAB is bounded by the Pacific Ocean to the west;the San Gabriel,San Bernardino and San Jacinto Mountains to the north and east;and the San Diego County line to the south. The SCAQMD also has jurisdiction over the Salton Sea Air Basin and a portion of the Mojave Desert in Riverside County. SCAQMD has not adopted any rules or regulations specific to global climate change or GHG emissions that are applicable to the Project. 3.2 Methodology GHG emissions generated by the Project would predominantly be in the form of carbon dioxide (CO2) and would occur primarily due to combustion sources including construction equipment and on-and off-road vehicle hips. GHG emissions from construction equipment were quantified using spreadsheets populated with horsepower-based composite emission factors, with built-in load factors. The emission factors were obtained from the SCAQMD's website(SCAQMD 2011)and represent the fleet-wide average emission factors during 2014 within the SCAB. GHG emissions from on-road motor vehicles were estimated using CARB's On-Road EMFAC201 I mobile source emission factors,obtained from the EMFAC2011 model output. 3.3 Significance of Impacts The previously certified PEIR did not contain an analysis of global climate change and GHG emissions.As mentioned earlier, amendments to the State CEQA Guidelines for climate change analyses became effective in March 2010. Therefore, climate change analyses were not necessarily required or included in environmental documents prior to this time. Nonetheless, in order to fully analyze and disclose the Project's potential environmental consequences, OCSD has analyzed the Project's potential GHG emission impacts using State approved models. There are currently two interim significance thresholds for GHG emissions, established by SCAQMD and CARB. The SCAQMD adopted an interim threshold of 10,000 metric tons of carbon dioxide equivalent per year(MTCOse/yr) for industrial projects, including both stationary and mobile source-related emissions (with construction impacts amortized over a 30-year period,plus operational impacts). The CARB interim threshold,which has been proposed but not yet been adopted, is 7,000 MTCOze/yr for non-transportation GHG emission sources, and includes interim performance standard requirements for construction equipment(which have yet to be defined). The SCAQMD interim threshold for industrial projects has been used for this analysis because it applies to mobile source emissions,which is the emission source for the Project construction activities. The analysis quantifies the annual GHG emissions that will result from project-related mobile sources during construction,and compares them to SCAQMD's Interim CEQA GHG Significance Threshold for Stationary Sources (SCAQMD 2008).As presented in Table 3-1,GHG emissions generated during construction would increase as a result 6 March 2015 of the proposed activities described above. However,the incremental increase would be less than 4.58 metric tons of carbon dioxide equivalents per year(MTCO2e/yr)and therefore would be less than significant. SCAQMDTable 3-1: Project GHG Emissions and CO2e Emissions Total Project CO2.Emissions During Construction, MTCO2e/Project 137.27 Amortized Construction GHG(over a 30-year period), MTCO2e130-yr 4.58 SCAQMD Interim GHG Threshold for Industrial Projects 10,000 Would the project exceed the SCAQMD interim threshold?(Yes/No) No Notes: 1. Detailed emission calculations are presented in Attachment 1. Source: Modeled by Rands AbuShaban, 2015 3.4 Application of CEQA Guidelines Would the project generate greenhouse gas emissions, either directly or indirectly, that may have a significant impact on the environment? Implementation ofthe Project would generate GHGs through the construction and routine maintenance ofthe Project. GHG emissions from the Project would specifically arise from the temporary direct sources, such as motor vehicles and construction related diesel equipment.Emissions from these sources were estimated using the Ca1EEMOd model based on default emission factors and land use consumption and generation rates. Emissions of greenhouse gases are presented in terms of metric tons of CO2 equivalents (MTCO2e). CO2e is the combination of all greenhouse gas impacts when normalized by comparing the effects of the impacts of each individual gas to that of a reference gas (CO2).This metric allows for the representation of greenhouse gas impacts as a single number. Table 3-1 shows the estimated GHG emissions with respect to the Project.It should be noted that the mitigation measures identified in the certified Air Quality section of the PEIR serve to reduce fugitive dust pollutants and would not reduce GHG emissions. As such, the GHG emissions identified in Table 3-1 reflect the estimated emissions without the incorporation of mitigation identified in the certified PEIR. Based on these calculations, construction of the Project would result in emissions of 137.27 MT CO2e/year and, therefore, would be below the SCAQMD's screening-level threshold. The impact of the Project would be less than significant and no mitigation is required. Would the project conflict with any applicable plan,policy,or regulation adopted for the purpose of reducing the emissions ofgmenhouse gases? The County Board of Supervisors adopted a countywide energy and environmental policy (Policy No. 3.045) to provide guidelines for development, implementation, and enhancement of energy conservation and environmental programs within the County.AB 32 established the goal of reducing GHG emissions in California to 1990 levels by 2020.The proposed SCAQMD screening-level thresholds are designed such that a 90 percent capture rate is achieved. This 90 percent capture rate means that 90 percent of all development projects would need to incorporate some form of emission reductions in order to reduce emissions. These rates are established to be compliant with the AB 32 threshold of reducing GHG emissions to 1990 levels by 2020. The Project's GHG emissions would be below the SCAQMD's screening-level threshold,and thus would not conflict with AB 32 and Policy No.3.045.Because the Project is compliant with the SCAQMD screening threshold and would comply with all regulatory requirements related to GHG emissions,the Project would not conflict with plans,policies, or regulations adopted to reduce GHG emissions. The impact of the Project would be less than significant and no mitigation is required. 7 March 2015 4.0 REFERENCES Orange County Sanitation District,March,2007.

(Exhibits 1 and 2) Mitigation Measure Impact 3.4-1 requires the evaluation of resources of sufficient age discovered within the Project APE that will be impacted by Project Activities. OCSD has found that the sewer trunk line located within the APE was constructed in the 1950s and under Section 15064.5 of the California Environmental Quality Act (CEQA)the built- environment resource appears to have reached sufficient age to be evaluated for significance as a potential historical resource. Daly&Associates performed a study to identify any potential historical resources that may be impacted by implementation of the proposed project, and to facilitate initial environmental compliance of the project under the provisions of CEQA. The investigation consisted of a windshield survey of the project area, research into the historic development of the area, and a review of individual property information available from OCSD. The purpose of this study is to ascertain if there are any built-environment resources in the APE that may be associated with the lives of persons important in our past;that were associated with any important patterns or events in local,state or national history; or that were constructed or designed by important individuals, and that would suffer a substantial adverse change as a result of the proposed project.

The removal and replacement of the existing District 6 Trunk Sewer pipelines would require a trench 4 feet wide and 14 feet deep. Trenches would be braced using a trench box or speed shoring. The active work are along the open trench would extend about 5 to 10 feet to one side of the trench and 20 to 30 feet to the other side, allowing for access by trucks and loaders. The minimum construction right-of-way would be 25 feet;the maximum construction easement would be 50 feet wide. On narrower residential streets, road closures and parking restrictions might be imposed during construction periods to facilitate traffic flow around construction areas. Construction work in intersections might necessitate closures when the construction precludes safe traffic or work conditions. Major sewer connections could require several days of uninterruptible round-the-clock activity. Staging areas would be necessary along the construction routes. Construction equipment and materials would be held in parking lots, vacant lots, or segments of street lanes that are temporarily closed. Staging areas would be selected to minimize hauling distances and long-term disruption. Removed pavement and excavated soil and pipes would be hauled offsite and would be disposed in accordance with applicable state and local regulations. Imported backfill would be delivered to stockpiles near the open trench. Once the new pipeline is in place, backfill would be placed in the trench, and the streets would be compacted and paved in accordance with state and local building codes. Description of the built-environment resource In the early history of Orange County, cities and towns located near large bodies of water or strong rivers were still discharging their mostly untreated sewer waste directly into the natural resources. This was a large cause of water pollution and created "dead" waterways. The practice of dumping sewage was not only harmful to the environment, but was a wasteful use of water. Leonard Metcalf and Harrison P. Eddy wrote the seminal textbooks on the "modern" treatment of sewage in 1914 with their three volume discourse American Sewerage Practice. Those books were followed by Sewerage and Sewage Disposal in 1922. Metcalf and Eddy included in their teachings the possibilities of the reuse of waste water, and presented the techniques for the "cleaning" of waste water for reuse. The water that was final product of the techniques developed in the 1920s was primarily left to drain naturally back to surrounding waterways or as groundwater. By the 1930s engineering systems were developed to drive the water, under pressure, directly back into the local water OCSD Project No.6-17 BonTerra Psomas Page 5 of 8 table thereby "recharging" a communities own water resource. Once treated, the water appears to have been injected back into the water table under pressure, and also by natural filtration in the treatment lagoons. According to the history of the OCSD, District 6 was formally organized under the County Sanitary District Act of 1923 in 1947. (orange County Sanitation District: History. http://Www.ocsd.COM/about-ocsd/general-information/history) Per sheets 4 and 5 of the engineering drawings of Sanitary Trunk Sewers OCSD District No. 6, dated 1952,the pipeline and manholes were constructed of pre-cast concrete units with cast iron manhole covers. While the manhole covers with the OCSD Sewer would have been cast using a custom mold,the iron covers and the concrete pipes were common components of a 1950s sewer line. (http://www.sewerhistory.org/grfx.htm) (Exhibits 3 and 4) a Exhibit 3: Manhole cover from District 6 Trunk Sewer line, Ohms Way,Costa Mesa.

The Directory of Historic Property Data for Orange County maintained by the California Office of Historic Preservation (OHP) was reviewed to ascertain if the District 6 Trunk Sewer pipeline in the APE had been previously evaluated. The sewer line located in the APE has not been evaluated for listing in the National Register of Historic Places,the California Register of Historical Resources, or as a historic resource in the City of Costa Mesa or Newport Beach. Assessment of Project Impacts CEOA defines a substantial adverse change as physical demolition, destruction, relocation, or alteration of the resource or its immediate surroundings such that the significance of a historical resource would be materially impaired.The significance of a historic resource is materially impaired when a project: Demolishes or materially alters in an adverse manner those physical characteristics of a historical resource that convey its historical significance and that justify its inclusion in, or eligibility for, inclusion in the California Register of Historical Resources. The treatment of sewage treatment and construction of water reclamation systems is associated with community planning and development issues that came to the forefront in the early twentieth century when the results of uncontrolled dumping of waste products in rivers and oceans began to negatively impact the human settlements located in close proximity to bodies of water. It was becoming apparent that the dumping of waste was not only offensive in sight and smell, but that the untreated waste was literally killing the biosystems that were dependent on fresh water and salt water environments. Engineers specializing in water resources and sewage began to publish instructional handbooks and technical texts to assist communities on how to construct a system that would breakdown waste products that could be reused as fertilizer, and not foul the local water systems. Not too many years later, it became apparent, especially in the southwestern states,that all water should be considered a valuable resource and reused in the local community. Before water was injected back into the underground water table, "cleaned" water was sent back to open waterways, or left to evaporate. The pipelines of the District 6 Trunk Sewer are constructed of precast concrete and metal components commonly found in almost every city in the United States. They are considered ordinary and ubiquitous built-environment resources that are subject to routine maintenance, OCSD Project No.6-17 BonTerra Psomas Page 8 of 8 repairs, and improvements. The District 6 Trunk Sewer pipelines have not been found to be associated with any important event or person in Orange County or California. The District 6 Trunk Sewer pipelines are merely one of many conduits in the ODSD system whose sole purpose is to carry waste material, and the specific segment within the APE does not appear to present any innovative waste management engineering techniques. Conclusion Based upon the windshield survey of the built-environment resources in the project area, and a review of the engineering drawings of the components of the District 6 Trunk Sewer pipelines, it does not appear that the proposed project would result in a significant adverse impact to any identified or eligible historic resources. In accordance with Mitigation Measure 3.4-1 of the Final Program Environmental Impact Report of the Collection System Improvement Plan for OCSD,the District 6 Trunk Sewer pipeline has been determined not to meet the criteria necessary to be identified as a historical resource as defined by 14 CCR§4850, PRC§ 21084.1, 14 CCR § 15064.5(3) of the California Environmental Quality Act.

This will be performed by providing a recommended up-sized design for the Lower Portion of this sewer. The Mid and Upper Portions do not require an increase in hydraulic capacity, the Mid Portion does have structural and corrosion issues that are affecting the hydraulic capacity. These portions will require rehabilitation or replacement. A cost-effective solution must be determined so the service life of the 6-17 sewer may be extended by 30 years. An engineered access solution shall also be provided for existing manhole number BPT0165-0000. Significant items include drawings, specifications, schedules, cost estimates, completed permitting, public outreach, traffic control, sewage bypassing, and temporary odor-control system design for use during construction. BonTerra Psomas was contracted to conduct a cultural resources investigation for the sewer alignment to determine if any existing cultural resources might be impacted during future modifications to the pipeline. This report documents the results of that study and includes a sensitivity map depicting the relative sensitivity of the pipeline alignment for potential impacts to recorded or unknown cultural resources. DATES OF INVESTIGATION BonTerra Psomas initiated the project on August 4, 2014, by conducting the records search at the South Central Coastal Information Center (SCCIC) at California State University, Fullerton (Attachment A). The Native American Heritage Commission was notified of the project on August 22, 2015. Notification letters were mailed to nine tribes on August 25, 2014 and the project area underwent a vehicular windshield survey on August 21, 2014. This draft report was submitted to the Orange County Sanitation District (OCSD) on September 10, 2014. INVESTIGATION CONSTRAINTS The entire route of the trunk sewer is obscured by modern elements of the built environment, consisting primarily of asphalt paving and concrete driveways and slabs. The sewer is at least 60 years old and should be considered historically sensitive. MITIGATION MM 1: Cultural Resources Monitorina Section 21083.2(i) of the CEQA Statutes and Section 15064.5(f) of the State CEQA Guidelines provide for the accidental discovery of historical resources during construction. Based on the fact that prehistoric, historic, and modern peoples made use of the project alignment and surrounding areas, it is not unlikely that previously undetected cultural material and unknown archaeological sites could exist beneath pavement and other modern structures. Therefore, it is recommended that a qualified Archaeologist who meets the Secretary of the Interior's Standards for Archaeologists (NIPS 1983) and Native American Tribal Monitor(s) of the local Juanefio and/or Gabrielino tribal groups (identified by the Native American Heritage Commission [NAHC]), who have historical ties to the general area monitor excavations in sensitive sediments associated with the project. R:mrgaoia=D(=)A. oscuwmMa aec R e91214.d= S-2 NADa Information Sheef OCSD Dlattict 6 Trunk Sewer Relief Pmjecl(No.6-17) In the event that cultural resources are exposed during construction, the archaeological monitor shall have the authority to temporarily halt construction in the immediate vicinity of the discovery while it is evaluated for significance; if this occurs, construction activities could continue in other areas. If the discovery is determined to be significant, additional work (such as data recovery excavation) may be warranted. A Registered Professional Archaeologist should, at minimum, supervise any monitoring activities. Prior to the issuance of the first grading permit and/or action that would permit project site disturbance, the Contractor shall provide written evidence to the OCSD that the Contractor has retained a qualified Archaeologist to observe grading/site disturbance activities and to salvage and catalogue archaeological resources, as necessary. The Archaeologist shall be present at the pre-grade conference; shall establish procedures for archaeological resource surveillance; and shall establish, in cooperation with the Contractor, procedures for temporarily halting or redirecting work to allow the sampling, identification, and evaluation of the artifacts, as appropriate. If the archaeological resources are found to be significant, the Archaeologist shall determine appropriate actions in cooperation with the City and Contractor for exploration and/or salvage. These actions, as well as final mitigation and disposition of the resources, shall be subject to the approval of the Planning Director. Based on their interest and concern about the discovery of cultural resources and human remains during project grading, a Native American Monitor shall be retained to observe some or all grading activities. MM 2: Site Recordina The sewer is estimated to be 60 years old; minimally, it should be recorded on a standard Department of Parks and Recreation (DPR) 523 primary record form. Prior to any construction activities that could impact the sewer, an evaluation pursuant to Section 15064.5 of the State CEQA Guidelines should be accomplished to determine if it is eligible for listing in the California Register of Historical Resources. REGULATORY REQUIREMENTS RR 1: Human Remains In accordance with Section 7050.5 of the California Health and Safety Code, if human remains are found, the County Coroner shall be notified within 24 hours of the discovery. No further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains shall occur until the County Coroner has determined, within two working days of notification of the discovery, the appropriate treatment and disposition of the human remains. If the County Coroner determines that the remains are or believed to be Native American, s/he shall notify the Native American Heritage Commission (NAHC) in Sacramento within 24 hours. In accordance with Section 5097.98 of the California Public Resources Code, the NAHC must immediately notify those persons it believes to be the most likely descended (MILD) from the deceased Native American. The MILD(s) shall complete their inspection within 48 hours of being granted access to the site. The MILD would then determine, in consultation with the property owner, the disposition of the human remains. With implementation of the mitigation program summarized above, potential impacts to archaeological resources would be reduced to a level considered less than significant. DISPOSITION OF DATA This report will be filed with the Orange County Sanitation District, the Project Applicant, BonTerra Psomas, and at the SCCIC at California State University, Fullerton.

Federal and State regulations are included, as it is possible that both California Environmental Quality Act (CEQA) and National Historic Preservation Act (NHPA) regulations would apply. The report is intended to satisfy the requirements of (1) the CEQA statutes (California Public Resources Code §21083.2) and the State CEQA Guidelines (14 California Code of Regulations [CCR] §15064.5); (2) Section 106 of the NHPA (36 Code of Federal Regulations [CFR] 800, Protection of Historic Properties); and (3) a review by the U.S. Army Corps of Engineers (USACE) and State Historic Preservation Officer (SHPO) relative to a possible Clean Water Act (CWA)404 Permit for the proposed project. Federal Cultural resources are considered during federal undertakings chiefly under Section 106 of the NHPA of 1966 (as amended) through one of its implementing regulations (36 CFR 800) and under the National Environmental Policy Act (NEPA). Properties of traditional religious and cultural importance to Native Americans are considered under Section 101(d)(6)(A) of the NHPA. Other federal laws include the Archaeological Data Preservation Act of 1974, the American Indian Religious Freedom Act (AIRFA) of 1978, the Archaeological Resources Protection Act of 1979, and the Native American Graves Protection and Repatriation Act of 1989, among others. Section 106 of the NHPA (16 United States Code [USC] 470f) requires federal agencies to (1)take into account the effects of their undertakings on any district, site, building, structure, or object that is included in or eligible for inclusion in the NRHP and (2) afford the Advisory Council on Historic Preservation (ACHP) a reasonable opportunity to comment on such undertakings (36 CFR 800.1). Under Section 106 of the NHPA, the significance of any adverse effect on a cultural resource is assessed and mitigation measures are proposed to reduce the impacts to an acceptable level. Significant cultural resources are those resources that are listed in or are eligible for listing in the NRHP per the criteria listed at 36 CFR 60.4 below. The quality of significance in American history, architecture, archaeology, engineering, and culture is present in districts, sites, buildings, structures, and objects that possess integrity of location, design, setting, materials, workmanship, feeling, and association and that: (a) Are associated with events that have made a significant contribution to the broad patterns of our history; or (b) Are associated with the lives of persons significant in our past; or (c) Embody the distinctive characteristics of a type, period, or method of installation, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or (d) Have yielded, or may be likely to yield, information important in prehistory or history. R:w,gecis=D(=]A. oscuwmMa eeca ee1214.d= 1 Guttural Resources Assessment OCSD Dlsltict 6 Trunk Sewer Relief Projecl(No.6-17) State CEQA requires a lead agency to determine whether a project may have a significant effect on one or more historical resources. A "historical resource" is defined as a resource listed in, or determined to be eligible for listing in, the California Register of Historic Resources (CRHR) (California Public Resources Code§21084.1); a resource included in a local register of historical resources (14 CCR §15064.5[a][21); or any object, building, structure, site, area, place, record, or manuscript which a lead agency determines to be historically significant (14 CCR §15064.5[a][3]). Section 5024.1 of the California Public Resources Code, Section 15064.5 of the State CEQA Guidelines, and Sections 21083.2 and 21084.1 of the CEQA Statutes were used as the basic guidelines for the cultural resources study. Section 5024.1 of the California Public Resources Code requires evaluation of historical resources to determine their eligibility for listing in the CRHR. The purposes of the CRHR are to maintain listings of the State's historical resources and to indicate which properties are to be protected from substantial adverse change. The criteria for listing resources in the CRHR were expressly developed to be in accordance with previously established criteria developed for listing on the NRHP. Section 15064.5(a)(3) of the CEQA Guidelines states that "[g]enerally, a resource shall be considered by the Lead Agency to be 'historically significant' if the resource meets the criteria for listing on the California Register of Historical Resources" (California Public Resources Code §5024.1), including if the resource: A. Is associated with events that have made a significant contribution to the broad patterns of California's history and cultural heritage; B. Is associated with lives of persons important in our past; C. Embodies the distinctive characteristics of a type, period, region, or method of construction, or represents the work of an important creative individual, or possesses high artistic values; or D. Has yielded, or may be likely to yield, information important in prehistory or history. The lead agency shall concurrently determine whether a project will cause damage to a unique archaeological resource (as defined in California Public Resources Code §21083.2[b]) and, if so, must make reasonable efforts to permit the resources to be preserved in place or left undisturbed. Section 21083.2(g) of the California Public Resources Code defines a unique archaeological resource as an archaeological artifact, object, or site about which it can be demonstrated that without merely adding to the existing body of archaeological knowledge, there is a high probability that it meets any of the following criteria: 1. It contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information. 2. It has a special and particular quality such as being the oldest of its type or the best available example of its type. 3. It is directly associated with a scientifically recognized important prehistoric or historic event or person. To the extent that unique archaeological resources are not preserved in place, mitigation measures shall be required (California Public Resources Code §21083.2[c]). R:�ocso(=)A. oscuwmMa aecR e91214.d= 2 Guttural Resources Assessment OCSD Dlsfticl6 Trunk Sewer Relief Pmjecl(No. 6-17) Using the information outlined above, the first level of evaluation is to determine whether a resource on a site is a historical resource and/or a unique archaeological resource that would be considered eligible for the CRHR and, therefore, significant. Impacts to significant cultural resources that affect those characteristics of the resource, that qualify it for the CRHR, or that adversely alter the significance of a resource listed in or eligible for listing in the CRHR are considered a significant effect on the environment. Impacts to cultural resources are considered significant if a project (1) physically destroys or damages all or part of a resource; (2) changes the character of the use of the resource or physical feature within the setting of the resource that contributes to its significance; and/or (3) introduces visual, atmospheric, or audible elements that diminish the integrity of significant features of the resource. The purpose of the current study is to evaluate the eligibility of 11 sites on the project for listing on the CRHR and the NRHP. City of Newport Beach The City of Newport Beach has adopted archaeological guidelines that govern the identification and evaluation of cultural resources and are used to guide the development or redevelopment of lands in the City. The discussion below is adapted from the City Council Policy Manual Guidelines. The archaeological guidelines, Policy K-5, adopted on January 13, 1975, amended on January 24, 1994, and corrected on March 22, 1999, and amended on September 27, 2011 are summarized below: A. The City shall, through its planning policies and permit conditions, insure the preservation of significant archaeological resources and require that the impact caused by any development be mitigated in accordance with the California Environmental Quality Act. B. The City shall prepare and maintain sources of information regarding archaeological sites and the names and addresses of responsible organizations and qualified individuals who can analyze, classify, record, and preserve archaeological findings. C. If determined to be necessary by the Planning Director, it shall be the responsibility of a landowner or developer prior to the commencement of land development to cause the proposed site to be examined to determine the existence and extent of archaeological resources. The examination shall be by qualified observers, approved by the City. The observers shall prepare and submit to the City a written report describing findings and making recommendations for further action. The report shall discuss both positive and negative aspects of the effects of the proposed development on archaeological resources. The report shall be considered as part of the CEQA review process and, if appropriate, the recommendations shall be included as mitigation measures and conditions of approval for the project. D. Based on the report and recommendations of the observers, the City shall take such steps as are necessary to assure that any findings or sites are recorded, preserved and protected. These steps may include requiring the landowner or developers to incur reasonable expenditures of time or money, encouraging the involvement of appropriate volunteer or non-profit organizations or acquisition of R:mrgeomocso(=)A. oscuwmMa aecR e91214.d= 3 Guttural Resources Assessment OCSD Dlstnd 6 Trunk Sewer Relief Project(No.6-17) the sites by public or private agencies. Provision shall be made for the deposit of scientifically valuable archaeological materials which are removed from the site with responsible public or private institutions. In all cases, the City shall seek responsible scientific advice and make the necessary decisions consistent with the public interest. 2.0 PROJECT SITE Exhibit 1 shows a portion of the U.S. Geological Survey (USGS)7.5-minute Newport Beach, CA quadrangle, which depicts the specific location of the project alignment. Generally, the sewer follows Newport Boulevard northward from the Pacific Coast Highway turning slightly northwest at Orange Avenue until it crosses Superior Avenue then turns north at 16'^ Street. From there is follows an alley, then Ohms Way. It enters an industrial complex via a driveway and exits midway turning right and ending at Pomona Avenue. 3.0 CULTURAL SETTING 3.1.1 Prehistory Archaeologists and ethnologists have long pondered over the cultural sequences that occurred before Spanish contact. The two most currently accepted schemes are those proposed by Wallace (1955), who interpreted the prehistory of coastal Southern California through temporal horizons, and Warren (1968), who viewed cultural differences not as temporal distinctions, but as local traditions. Wallace (1955) saw four temporal horizons along the Southern California coast: Early Man, Milling Stone, Intermediate, and Late Prehistoric. Early Man Horizon Spanning the period from the end of the Pleistocene to approximately 8,000 years before present (YBP),' archaeological assemblages attributed to this horizon are characterized by large projectile points and scrapers. The limited data available suggests that prehistoric populations focused on hunting and gathering and moved about the region in small nomadic groups. Milling Stone Horizon Characterized by the appearance of handstones and millingstones, this horizon tentatively dates to between 8,000 YBP and 3,000 YBP. Assemblages in the early Milling Stone Horizon reflect an emphasis on plant foods and foraging subsistence systems. For inland locales, it has been assumed that grass seed exploitation formed a primary subsistence activity. Artifact assemblages include choppers and scraper planes, but generally lack projectile points. The appearance of large projectile points in the latter portion of the Milling Stone Horizon suggests a more diverse economy. The distribution of Milling Stone sites reflects the theory that aboriginal groups may have followed a modified, centrally based wandering settlement pattern. In this semi-sedentary pattern, a base camp would have been occupied for a portion of the year, but a small population group seasonally occupied subsidiary camps in order to exploit resources not generally available near the base camp. Sedentism apparently increased in areas possessing an abundance of resources available for longer periods of time. More and inland regions would have provided a seasonally dispersed resource base, restricting sedentary occupation. ' "Years Before Present"assumes that 1950 is"present,"so in this case 8,000 YBP would be 6,050 BCE.

OCSD Dlsftict 6 Trunk Sewer Relief Pmjecl(No.6-17) Intermediate Horizon Dated to between 3,000 YBP and 1,350 YBP, the Intermediate Horizon represents a transitional period. Little is known about the people of this period, especially those of inland Southern California. Site assemblages retain many attributes of the Milling Stone Horizon. Additionally, Intermediate Horizon sites contain large stemmed or notched projectile points and portable mortars and pestles. The mortars and pestles suggest that the aboriginal populations may have harvested, processed, and consumed acorns. Neither the settlement-subsistence system nor the cultural evolution of this period has been well understood due to a general lack of data. It has been proposed that sedentism increased with the exploitation of storable food resources (acorns); the duration and intensity of base camp occupation increased, especially toward the latter part of this horizon. Late Prehistoric Horizon Extending from the year 750 to Spanish contact in 1763, the Late Prehistoric Horizon reflects an increased sophistication and diversity in technology. This is characterized by the presence of small projectile points that simplified the use of the bow and arrow. In addition, assemblages include steatite bowls, asphaltum, grave goods, and elaborate shell ornaments. Use of bedrock milling stations was widespread during this horizon. Increased hunting efficiency and widespread exploitation on acorns provided reliable and storable food resources. These innovations apparently promoted greater sedentism. By contrast, Warren's (1968) cultural traditions were more restricted spatially. Warren's scheme accounted for the cultural variability particularly evident within Wallace's late Prehistoric Horizon. Warren's traditions include the San Dieguito, Encinitas, Campbell, Chumash, Shoshonean, and Yuman. The San Dieguito tradition occurs within Wallace's Early Man Horizon, but is restricted to San Diego County. The Encinitas equated to Wallace's Milling Stone, but was longer in time, encompassing Wallace's Intermediate Horizon. Warren saw no new tradition developing in northern San Diego and Orange Counties during this time period. The Campbell and Chumash traditions are farther north in Santa Barbara and Ventura Counties. In Los Angeles, Orange, and North San Diego Counties, the Shoshonean Tradition began about 1300 YBP and represents the intrusion of Shoshonean speakers from the interior (Warren 1968). In contrast, the Yuman Tradition in southern San Diego County, just as the Chumash Tradition to the north, is thought to have developed from previous local traditions, whereas the Shoshonean Tradition is the result of intrusion into a previous tradition (Mason 1991:95). Koerper (1981) and Koerper and Drover (1983) have taken the horizon system proposed by Wallace and have applied it more specifically to the prehistory of Orange County. Koerper (1981) and Koerper and Drover (1983) adapted Wallace's four horizons using artifacts and associated radiocarbon dates from two Orange County sites: CA-ORA-64 and CA-ORA- 119-A. The authors argued that the transition between the Milling Stone and Intermediate Horizons was marked by the appearance of the mortar and pestle. The primary projectile point type changed from the Milling Stone "Pinto Basin"to the stemmed and side-notched forms. The beginning of the Late Prehistoric Period occurred roughly with the appearance of the smaller "Cottonwood" points, suggesting the introduction of the bow and arrow, and also with the abundance of shell beads and ornaments; the use of steatite for pipes, bowls, and ornaments; and the emergence of arrow shaft straighteners. Pottery may or may not appear at the end of the late Prehistoric Period or the Historic Period (Koerper and Drover 1983). R:mrgama=D(=]A. oscuwmMa aecR e91214.d= 5 Guttural Resources Assessment OCSD Disffid 6 Trunk Sewer Refie/Project(No.6-17) Mason and Peterson (1994) have proposed subdividing Wallace's Milling Stone Horizon into three subdivisions; the Intermediate into two subdivisions; and the late Prehistoric into two subdivisions. These temporal subdivisions are based entirely on radiocarbon age determinations that correspond to some degree with changes in settlement (Mason and Peterson 1994:58). In contrast, they note that temporal subdivisions traditionally have been defined on supposed differences in cultural content or traits as presented by Willey and Phillips (1958:22). As shown in Table 1, Mason and Peterson found little difference in the cultural content of their three Milling Stone subdivisions. TABLE 1 CULTURAL SEQUENCE FOR ORANGE COUNTY Cultural Period Radiocarbon Dates Paleo-Coastal Period PC Prior to 8000 YBP Milling Stone Period MS1 8000 to 5800 YBP MS2 5800 to 4650 YBP MS3 4650 to 3000 YBP Intermediate Period INTt 3000 to 2300 YBP INT2 2300 to 1350 YBP Late Prehistoric Period LP1 1350 to 650 YBP LP2 650 to 200 YBP Source:Mason and Peterson 1994 During the Newport Coast Archaeological Project, the Intermediate Horizon was not subdivided because only ten radiocarbon dates were available. Mason and Peterson were confident that the Intermediate Horizon could also be subdivided once calibrated dates were available from a wider region of the Newport Coast (Mason and Peterson 1994:58), and for that matter, all of Orange County or Southern California. The authors argue that, although their temporary subdivisions do not correspond with changes in stylistically defined artifact types, they may correspond with changes in settlement systems (Mason and Peterson 1994:58). The Intermediate Horizon was subdivided in Roger Mason's report on CA-ORA-225 (Mason at al. 1997b). Mason defined 3 periods based on 18 radiocarbon dates. These three divisions are Late Intermediate (1700-1350 YBP), Middle Intermediate (2300-1700 YBP) and Early Intermediate (3100-2300 YBP). Due to the small sample of radiocarbon dates, Mason at al notes that the Intermediate subdivisions could only be applied to CA-ORA-225 and not regionally. As a result of the Bonita Mesa Archaeological Project (document in progress), the Intermediate Period was redefined. A total of 72 radiocarbon dates from 6 sites were used to redefine the Intermediate. The Intermediate was divided into two periods: the late part of the Intermediate or INT2 (1350-2300 YBP) and the early part of the Intermediate or INT1 (2300- 3000 YBP). 3.1.2 Ethnohistory At the time of European contact in 1769, the Santa Ana plain was occupied by the Gabrielino Native Americans, so called by the Spanish after the nearby Mission San Gabriel Archangel. According to Bean and Smith (1978:538), the Gabrielino are, in many ways, one of the least known groups of California native inhabitants. In addition to much of the Los Angeles Basin, a:wgeo =D(acspwooscuwmMneed ae 91214.d= 6 Guttural Resources Assessment OCSD D1sltict 6 Trunk Sewer Relief Pmjecl(No.6-17) they occupied the offshore islands of Santa Catalina, San Nicolas, and San Clemente. Gabrielino populations are difficult to reconstruct; however, at any one time, as many as 50 to 100 villages were simultaneously occupied. Like the prehistoric culture before them, the Gabrielino were a hunter/gatherer group who lived in small sedentary or semi-sedentary groups, termed Rancherias, of 50 to 100 persons. These Rancherias were occupied by at least some people all of the time. Location of the encampment was determined by water availability. Within each village, houses were circular in form and constructed of sticks covered with thatch or mats. Each village had a sweat lodge and a sacred enclosure (Bean and Smith 1978). Their subsistence relied heavily on plant foods, but was supplemented with a variety of meat, especially from marine resources. Food procurement consisted of hunting and fishing carried out by men, and gathering of plant foods and shellfish by women. Hunting technology included bow and arrow use for deer and smaller game, in addition to stick-throwing, snares, traps, and slings. Fishing was conducted with the use of shell fishhooks, bone harpoons, and nets. Seeds were gathered with beaters and baskets. Food was stored in baskets. It was prepared with manos and metates, and mortars and pestles. Food was cooked in baskets coated with asphaltum, in stone pots, on steatite frying pans, and by roasting in earthen ovens (Bean and Smith 1978). Although the earliest description of the Gabrielino dates back to the Cabrillo expedition of 1542, the most important and extensive accounts were those written by Father Geronimo Boscana circa 1822 and Hugo Reid in 1852. Major Gabrielino villages south of the City of Long Beach apparently included Lukpa and Kengaa, also known as Gengara. Moyoonga is another place name cited by Kroeber (1907), but it is unclear if this was a community or a geographical designation (McCawley 1996:72). According to mission records, Kengaa may have been occupied as late as 1828 or 1829 (Merriam 1968). The place name was still used as late as 1853 identifying Newport Bay as "bolsa de gengara". Archaeological evidence suggests that CA-ORA-119A or CA-ORA-111 may be the remains of this important village. The other village, Lukpa, was, according to one of Kroeber's Native American informants, located in the City of Huntington Beach. One possibility is the Newland Site excavated by Winterboume in the 1930S and more recently by other investigators. During the early 1900s, important ethnographic studies were conducted by several researchers including Alfred L. Kroeber, John P Harrington, C. Hart Merriam, W.D. Strong, and J.W. Hudson. Each of these men was able to interview members of the Gabrielino who had living experience with the Mission period when the group was in transition. Central Orange County was shared by both the Juaneno (another Native American tribal group so named because of its association with Mission San Juan Capistrano) and Gabrielino. The three place names associated with central Orange County are Gangs, Pasbengna, and Hutuknga. Genga was located at CA-ORA-58 in what today is Fairview Park in the City of Costa Mesa. Pasbengna was located along the Santa Ana River approximately where the City of Santa Ana is today, and appears on the 1846 map drafted by Alexander Taylor. The third site, Hutuknga, is located where the City of Yorba Linda exists today (Earle and O'Neil 1994). The Gabrielino are frequently thought to have been the dominant ethnohistoric group in Orange County (e.g., Kroeber 1925). Earle and O'Neil have determined that sites along the Santa Ana River afforded pivotal political exchange and social interaction between the Gabrielino and Juaneno (1994). Based on Mission marriage records, the villages along the Santa Ana River apparently consisted of multi-ethnic populations (Earle and O'Neil 1994). Among the more significant sites along the northern coast of Orange County was the complex of sites surrounding Boise Chica, including CA-ORA-83, known as the "Cog Stone" site or the "Griset Site". As with Boise Chica, Newport Bay is surrounded by a number of prehistoric sites. The sites along the southern Orange County coast in the San Joaquin Hills include the multi-component complexes at Bonita Mesa, Pelican Hill, and Shady Canyon.

Smith conducted a cultural resources records search and literature review at the South Central Coastal Information Center (SCCIC) at California State University, Fullerton on August 4, 2014, to determine if the property had been subject to a cultural resources survey and if any cultural resources had been recorded on or within a one-mile radius. The SCCIC is the designated branch of the California Historical Resources Information System (CHRIS) for the project area and houses records concerning archaeological and historic resources in Los Angeles, Ventura, and Orange Counties. Data sources reviewed include archaeological records, Archaeological Determinations of Eligibility, historic maps, and the Historic Property Data File (HPDF) maintained by the California Office of Historic Preservation. The HPDF contains listings for the CRHR and/or NRHP, California Historical Landmarks, and California Points of Historical Interest. 4.2 NATIVE AMERICAN HERITAGE COMMISSION (NAHC) SACRED LANDS FILE REVIEW On August 22, 2014, BonTerra Psomas notified the Native American Heritage Commission (NAHC) of the proposed project. The NAHC conducted a search of their Sacred Lands Inventory to determine if any cultural resources were located within the project area. The NAHC provided BonTerra Psomas a list of nine tribes affiliated with the project area and recommended they be contacted regarding any information or comments they may have pertaining to the project. On August 25, 2014, the following people were notified in writing of the proposed undertaking and were requested to provide any information they may have regarding the history or prehistory of the project area. • Sandonne Goade, Chairperson, Gabrielino/Tongva Nation; • John Tommy Rosas, Tribal Administrator, Tongva Ancestral Territorial Tribal Nation; • Anthony Morales, Chairperson, Gabrielino/Tongva San Gabriel Band of Mission Indians; • Sam Dunlap, Cultural Resources Director, Gabrielino Tongva Nation; • Robert Dorame, Tribal Chair/Cultural Resources, Gabrielino Tongva Indians of California Tribal Council; • Bennie Acuna, Chairperson, Gabrielino-Tongva Tribe; • Linda Candelaria, Chairwoman, Gabrielino-Tongva Tribe; • Andrew Sales, Chairperson, Gabrieleno Band of Mission Indians; and • Conrad Acuna, Gabrielino-Tongva Tribe. Each of these Native American groups and individuals were notified by mail of the proposed project on August 25, 2014 (Attachment B). The notifications included an invitation to provide comments or information regarding historic or prehistoric activities on or near the project alignment. 4.3 SITE VISIT On August 21, 2014, David M. Smith, a BonTerra Psomas Senior Archaeologist, conducted a vehicular survey of the project alignment. Any areas that were not accessible by vehicle were inspected via Google Earth. n:wgama=D(=]A. oscuwmMa aec ea e91214.d= 8 Guttural Resources Assessment OCSD Distnct 6 Trunk Sewer Relief Project(No.6-17) 5.0 RESULTS 5.1 RECORDS SEARCH The results of the records search indicate that at least 20 archaeological studies have been conducted within a '/:mile radius of the project area. Two of those studies included a portion of the project area (Table 2). John Romani provided an Archaeological Survey Report for the CA-ORA-55 Corridor in 1982. That study included the approximate southern 2/3 of the alignment, from Pacific Coast Highway north along Newport Boulevard until the alignment curves to the west near Orange Avenue (Table 2). That project resulted in updating CA-ORA-59 and CA-ORA-60, two shell middens initially recorded by Nelson in 1912 (Table 3). No new archaeological sites were discovered during that study. Also in 1982, Steele updated another shell midden site, CA-ORA-297,for a Historic Property Survey Report conducted along the same section of CA-ORA-55 (Table 2). The site was initially recorded by M. Ahlering in 1971 (Table 3). Another shell midden, CA-ORA-357, was recorded in by T. Elliott in 1973 during an unidentified project(Table 3). BonTerra Psomas also reviewed the Office of Historic Preservation's Historic Resources Inventory for Newport Beach to determine if any historic structures or objects had been recorded within a %2- mile radius of the project alignment. That review identified Our Lady Mount Carmel, a catholic church, located at 1441 Balboa Boulevard (Table 3). The building is not within the project alignment. Another structure, a modern office building, is also recorded within a %:mile radius of, but not within,the project alignment(Table 3).

Mr. Salas indicated that the "project is located in and around a sensitive area where traditional territories of the Gabrieleno still exist". Mr. Sales further expressed an interest in providing Native American monitors during any and all ground- disturbing activities that occur as part of the sewer project. 5.3 SITE VISIT The site visit was conducted to determine if activities associated with the Trunk Sewer Relief Project could impact significant cultural resources. A survey of the built environment indicates that the alignment does not impact significant historical resources. The Trunk Sewer is thought to be 60 years old. However, the existence of several recorded prehistoric archaeological sites near the alignment suggest that other, unrecorded, prehistoric resources could exist in a subsurface context within the project alignment. 5.3.1 Sensitivity Map The OCSD requested that BonTerra Psomas generate a sensitivity map depicting the relative sensitivity of the either the pipeline as a whole or various segments (Exhibit 2). In light of the records search, the alignment should be considered moderately to highly sensitive for buried historic and/or prehistoric resources. Certain areas are more sensitive than others, and these are depicted on Exhibit 2. 6.0 MITIGATION 6.1 MITIGATION The following recommended mitigation measures should be completed for this project. 6.1.1 MM 1: Cultural Resources Monitoring Prior to the issuance of the first grading permit and/or action that would permit Project site disturbance, the Contractor shall provide written evidence to the Orange County Sanitation District that the Contractor has retained a qualified Archaeologist to observe grading activities and to salvage and catalogue archaeological resources, as necessary. The Archaeologist shall be present at the pre-grade conference; shall establish procedures for archaeological resource surveillance; and shall establish, in cooperation with the Contractor, procedures for temporarily halting or redirecting work to permit the sampling, identification, and evaluation of the artifacts, as appropriate. If archaeological resources are found to be significant, the Archaeologist shall determine appropriate actions, in cooperation with the City and Contractor, for exploration and/or salvage. These actions, as well as final mitigation and disposition of the resources, shall be subject to the approval of the Planning Director. Based on their interest and concern about the discovery of cultural resources and human remains during Project grading, a Native American Monitor shall be retained to observe some or all grading activities. Nothing in this mitigation measure precludes the retention of a single cross-trained observer who is qualified to monitor for both archaeological and paleontological resources. n:wgeo =D(=)A. oscuwmMa eec Ee e91214.d= 10 Cultural Resources Assessment — Moderate agot,— High AN .wn a [�si w�'; �'*-•r ♦.\ V � -yam( T - s> L . r r OCSD Dlsftict 6 Trunk Sewer Relief Pmjecl(No.6-17) 6.1.2 MM 2: Site Recordina The sewer is estimated to be 60 years old; minimally, it should be recorded on a standard Office of Historic Preservation Department of Parks and Recreation (DPR) 523 primary record form. Prior to any construction activities that could impact the sewer, an evaluation pursuant to Section 15064.5 of the State CEQA Guidelines should be accomplished to determine if it is eligible for listing in the California Register of Historical Resources. 6.2 REGULATORY REQUIREMENTS 6.2.1 RR 3: Human Remains In accordance with Section 7050.5 of the California Health and Safety Code, if human remains are found, the County Coroner shall be notified within 24 hours of the discovery. No further excavation or disturbance of the site or any nearby area reasonably suspected to overlie adjacent remains shall occur until the County Coroner has determined, within two working days of notification of the discovery, the appropriate treatment and disposition of the human remains. If the County Coroner determines that the remains are or believes them to be Native American, s/he shall notify the Native American Heritage Commission (NAHC) in Sacramento within 48 hours. In accordance with Section 5097.98 of the California Public Resources Code, the NAHC must immediately notify those persons it believes to be the most likely descended (MLD) from the deceased Native American. The MLD(s) shall complete their inspection within 48 hours of being granted access to the site. The MILD would then determine, in consultation with the property owner, the disposition of the human remains. With implementation of the mitigation program listed above, potential impacts to archaeological resources would be reduced to a level considered less than significant. 7.0 CERTIFICATION I hereby certify that the statements furnished above and in the attached exhibits present the data and information required for this cultural resources report, and that the facts, statements, and information presented are true and correct to the best of my knowledge and belief. �DATE: September 2014 SIGNED: 44 "-74� David M.

This project does not require a General or Specific Plan amendment or adoption; therefore, the project is not subject to the statutory requirements of Senate Bill. At your earliest convenience, please conduct a search of the Sacred Lands File for the proposed project, located within Sections 21 and 28 (Township 6 South; Range 10 West) of the USGS Newport Beach, CA 7.5 Minute Quadrangle. Refer to attached exhibit. The primary goal of this project is to provide an engineered solution to the wet weather capacity issues that currently exist with a reasonable level of confidence that a sewage spill will not occur on the 6-17 sewer during a 10-year return interval storm event. This will be performed by providing a recommended up-sized design for the Lower Portion of this sewer. The Mid and Upper portions do not require an increase in hydraulic capacity. However, the Mid Portion does include structural and corrosion issues that are affecting the hydraulic capacity. These portions will require rehabilitation or replacement. A cost effective solution must be determined so the service life of the 6-17 sewer may be extended by 30 years. An engineered access solution will also be provided for existing manhole number BPT0165-0000. Please fax the results to me at (714) 444-9599, or e-mail to david.smith@psomas.com, referencing your letter to the "OCSD Project No. 6.17, District 6 Trunk Sewer Relief Project".

Dear Mr. Smith, A record search of the sacred land file has failed to indicate the presence of Native American cultural resources in the immediate project area. The absence of specific site information in the sacred lands file does not indicate the absence of cultural resources in any project area. Other sources of cultural resources should also be contacted for information regarding known and recorded sites. Enclosed is a list of Native Americans individuals/organizations who may have knowledge of cultural resources in the project area. The Commission makes no recommendation or preference of a single individual, or group over another. This list should provide a starting place in locating areas of potential adverse impact within the proposed project area. I suggest you contact all of those indicated, if they cannot supply information, they might recommend others with specific knowledge. By contacting all those listed, your organization will be better able to respond to claims of failure to consult with the appropriate tribe or group. If a response has not been received within two weeks of notification,the Commission requests that you follow-up with a telephone call to ensure that the project information has been received. lt you receive notification of change of addresses and phone numbers from any of these individuals or groups, please notify me. With your assistance we are able to assure that our lists contain current information. If you have any questions or need additional information, please contact me at(916) 373-3712.

In regards to the project here is some history near and around the project location. "The project locale lies in and around a sensitive area and where traditional territories of the Kizh(Kitc) Gabrieleno still exist , and which villages adjoined and overlapped with each other, at least during the Late Prehistoric and Protohistoric Periods. This village was known "Kengaa". The homeland of the Kizh(Kitc)Gabrieleno, probably the most influential Native American group in aboriginal southern California(Bean and Smith 1978a:538), was centered in the Los Angeles Basin, and reached as far east as the San Bernardino-Riverside area. The homeland of the Serranos was primarily the San Bernardino Mountains, including the slopes and lowlands on the north and south flanks.Whatever the linguistic affiliation, Native Americans in and around the project area echibited similar orgainization and resource procurement strategies. Villages were based on clan or lineage groups. Their home/base sites are marked by midden deposits, often with bedrock mortars. During their seasonal rounds to exploit plant resources, small groups would migrate within their traditional territory in search of specific plants and animals. Their gathering strategies often left behind signs of special use sites, usually grinding slicks on bedrock boulders, at the locations of the resources. Therefore our tribe would like to work respectfully together with your project and Archeologist to protect any and all of our cultural resources . We would like to request our services as Certifed Native American Monitors and to be present during any and all ground disturbances.

The project alignment is located within the City of Newport Beach, California. The approximate location of the project is shown on Figure 1 -Vicinity Map. 1.2 PROJECT AND SITE DESCRIPTION We understand the proposed project consists of reconstructing or rehabilitating an approximately 2,800-foot-long section of trunk sewer pipeline primarily located along the east side of Newport Boulevard and north of Pacific Coast Highway in the City of Newport Beach, California. The northern portion of the alignment will cross Newport Boulevard where it will tie into the existing sewer. The existing pipeline crosses Newport Boulevard to the south of Industrial Way and the proposed pipeline improvements will be located on the east side of Newport Boulevard. The trunk sewer pipeline project Will extend from manhole MH-170 (Station 20+48.04) on the north to manhole MH-25 (Station 48+14.35) on the south. The generalized project location is shown on Figure 2 - Subsurface Exploration Map. On the basis of conceptual information provided to us by RMC Water and Environment (RMC), we understand that a few different pipeline construction methodologies are being considered consisting of standard cut-and-cover construction and pipe bursting. The approximate limits where the various construction methodologies are proposed are presented on Chart 1 - Site Exploration Plan And Profile and Chart 1. We understand the re-constructed and rehabilitated pipeline will be approximately 12 to 18 inches in diameter and have an invert depth ranging between about 8 and 25 feet below the existing ground surface. New pipeline materials are expected to consist of VCP in the cut and cover sections and HDPE in the pipe-burst section. We understand the proposed trunk sewer pipeline improvements will consist of: • Cleaning and lining a 259-foot-long section of the existing sewer pipe between MH- 170 and MH-165; • Excavate and remove abandoned manhole (at Station 21+12.02) approximately 69 feet downstream of MH-170; • Relocate manhole MH-165 to the east shoulder of Newport Boulevard; • Realign the sewer pipeline and install new pipe between the relocated manhole MH-165 and manhole MH-145 using open cut construction, construct a new manhole in this realigned section between the relocated MH-165 and the existing MH-155; and • Install new pipeline between MH-145 and MH-025 using pipe bursting techniques. 4 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) In addition, the project will include improvements to various existing manholes and access facilities for maintenance purposes. The District 6 Trunk Sewer Relief Project area is located on the south-sloping portion of the Newport Mesa in the City of Newport Beach. The proposed project site slopes gently to the Pacific Ocean with ground surface elevations ranging from about El. +85 in the north to about +35 feet in the south. Existing topography along the pipeline alignment is shown on Chart 1 and Chart 1. The northern portion of the proposed pipeline alignment between about MH-165 (approx. Station 23+00) and MH-145 (Station 37+68.13) is located in landscaped shoulder areas of Newport Boulevard. Landscaping in the project area consists primarily of low-growth vegetation. The southern portion of the alignment consists of paved roadway and sidewalks between MH-145 (Station 37+68.13) and MH-020 (Station 48+14.35). 1.3 PURPOSE The purpose of this geotechnical study is to evaluate the geotechnical conditions in the vicinity of the proposed pipeline alignment by advancing site-specific soil borings and performing laboratory testing, and to provide opinions and geotechnical recommendations for design and construction of the proposed trunk sewer pipeline and related improvements. The project-specific subsurface exploration program consisted of advancing eight soil borings in the project area to depths of about 16.5 and 31.5 feet below the existing ground surface (bgs). The approximate locations of the soil borings are shown on Figure 2 - Subsurface Exploration Map. Locations explored for the project were selected by the project team. 1.4 PREVIOUS WORK Fugro provided a preliminary geotechnical report in 2013 (Fugro, 2013) to provide initial geotechnical engineering information to the project team and to assist in developing a preferred pipeline replacement technique. Principal tasks associated with our preliminary geotechnical study consisted of: • Reviewing of existing published geologic data and existing geotechnical data acquired by Caltrans and Law/Crandall in the vicinity of the proposed alignments; Meetings with staff from RMC's Irvine office to discuss the project elements and the conceptual pipeline alignments; and performing a site reconnaissance to observe the existing conditions along the proposed pipeline alignment; and • Preparing our preliminary geotechnical report for use in preliminary design of the project. 5 6R0 RMC Water and Environment M February 18,2013(Project No.04.61130008) 02 Geologic and geotechnical information from the data review and field reconnaissance were evaluated to characterize the potential subsurface conditions that may exist along the proposed pipeline alignment. Our work also included a preliminary discussion of potential geohazards that could affect the project during its design life. Subsurface exploration was not included in our scope of work for the preliminary geotechnical study. 1.5 WORK PERFORMED The scope of services performed for this study consisted of conducting a project-specific field exploration and laboratory-testing program, geotechnical engineering evaluation, and preparation of this report. The field exploration program was performed in general accordance with Task 2 of our proposal dated November 2, 2012. Our services were authorized by our agreement with RMC dated February 20, 2013. Work tasks performed for the project consisted of the following: 1.5.1 Permitting and Site Clearance Fugro reviewed the project plans and performed a site reconnaissance to locate the soil borings for site access, utility clearance, and permitting. Field exploration in the right-of-way of Newport Boulevard required encroachment permits from both the City of Newport Beach and the California Department of Transportation (Caltrans). Permitting and site clearance tasks consisted of: • Completed the Caltrans standard encroachment permit application and provided a work plan including traffic control plans for the proposed subsurface exploration. • Completed the City of Newport Beach encroachment permit application and obtained a permit from City of Newport Beach for temporary streettsidewalk closure. • Visited the site with a Caltrans permit inspector to observe the proposed boring locations for the presence of overhead and underground utilities and to determine drill rig accessibility prior to the start of the field exploration program. Fugro invited staff from RMC and OCSD to this field meeting. • Marked each boring location with white paint and contacted Underground Service Alert (USA) and verified that all agencies listed on the USA ticket had responded to ensure no conflicting underground utilities were marked or noted in the field at the boring locations. • Sent a work completion notice to Caltrans following the field exploration. 6 6R0 RMC Water and Environment IN February 18,2013(Project No.04.61130008) 1.5.2 Field Exploration The field exploration program consisted of excavating eight soil borings on October W and 15r", 2013. The soil borings were advanced along the proposed alignment to depths ranging between about 16.5 and 31.5 feet below ground surface. Drilling and sampling was performed by Martini Drilling, under subcontract to Fugro, using a CME 75 truck-mounted drill rig equipped with hollow-stem augers. The locations of the eight soil borings are presented on Figure 2 and Chart 1. Logs of borings are presented in Appendix A- Field Exploration. Table 1 below presents a summary of the borings, including completion depth and depth to groundwater, if encountered. Table 1.

Each boring location was sampled at approximately 2.5-foot to 5-foot intervals using 2- inch outside-diameter (OD) standard penetration test split spoon samplers and 3-inch OD modified California split-spoon samplers. The modified California sampler was used with 1-inch high brass ring liners. The samplers were driven into the materials at the bottom of the borehole using a 140-pound CME automatic-trip hammer. The blow count (N-value)was recorded, which is the number of blows from the hammer that were needed to drive the sampler 1 foot, after an 7 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) initial 6 inch seating interval. Bulk samples of material to a depth of up to about 5 feet of the ground surface were collected at each boring location. Organic Vapor Meter (OVM) readings were conducted on each sample from the soil borings in accordance with Orange County Environmental Health Department requirements. An engineer from Fugro logged the subsurface soil conditions in general accordance with ASTM D2488 and packaged the samples for transport to the laboratory for subsequent testing. Locations of each exploration were recorded using a hand-held GPS device. The sample intervals, recorded N-values, a description of the subsurface conditions encountered, pocket penetrometer readings, OVM readings (in parts per million), and other field and laboratory data are presented on the boring logs in Appendix A. Following logging and sampling at each location, all soil borings were backfilled to near the ground surface with cuttings and the asphalt pavement was patched with quick-set-cement that was dyed black. Any remaining cuttings were spread onsite. 1.5.3 Geotechnical Laboratory Testing Geotechnical laboratory testing was performed on selected earth materials sampled in the soil borings to characterize the materials and to aid in estimating relevant engineering design parameters. The testing program consisted of measurement of moisture/density, compaction, grain-size, plasticity, sand equivalent, R-value, shear strength, as well as limited chemical testing (pH, resistivity, sulfates, and chlorides). The laboratory test results are presented in Appendix B - Laboratory Testing. 1.5.4 Geotechnical Evaluation/Reporting We evaluated and analyzed the field and laboratory geotechnical data, developed opinions and geotechnical engineering recommendations to aid in the design and construction of the project, and prepared this report to summarize our findings, opinions and recommendations. Our report includes the following: • Descriptions of the regional geologic setting and site-specific soil and groundwater conditions encountered in explorations advanced at the site; • Discussion of seismic setting and potential geohazards; • Summary of existing pavement sections at the drill-hole locations; • A cross section depicting the interpreted subsurface site conditions along the proposed alignment based on preliminary profiles provided by RMC; • Geotechnical design parameters for trenchless construction and pipeline design; 8 6RO RMC Water and Environment M February 18,2013(Project No.04.61130008) • Foundation design parameters for project structural elements such as vaults or manholes; • Construction considerations; • Excavation and trenching conditions of soil units; • Evaluation of corrosion potential for buried ferrous metal and concrete; and • Suitability of excavated material for use as pipe zone backfill, trench backfill, and structure backfill material; 2.0 FINDINGS 2.1 GEOLOGIC SETTING 2.1.1 Regional Geology The project is located in the City of Newport Beach, California. The study area includes the broad southern margin of the Los Angeles Basin, which culminates abruptly with the Newport-Inglewood Uplift. This uplift is characterized by broadly warped coastal mesas of late Miocene to early Pleistocene marine sediments and late Pleistocene marine terrace deposits. The coastal mesas are deeply incised by the antecedent ancestral Santa Ana River system of late Pleistocene to early Holocene age. 2.1.2 Local Geology The project site is situated on a broad upland known as Newport Mesa that contains the central and northwestern portions of the City of Newport Beach. Newport Mesa extends southeast where it is divided from the San Joaquin Hills by stream and other erosional influences of the Newport Bay estuary system. The project site is about a mile north of the Pacific Ocean and two miles from the Santa Ana River. The site is underlain by Quaternary marine terrace deposits and alluvium. The project area is developed and the alluvial materials likely are overlain by artificial fill materials associated with roadway and other construction activities. The Newport-Inglewood fault zone is the closest such feature to the site and is located approximately 0.5 miles west/southwest of the project site. 2.2 SUBSURFACE CONDITIONS AND ENGINEERING PROPERTIES Subsurface materials encountered by the explorations generally consist of artificial fill materials and alluvial sediments to the depths explored (about 16.5 to 31.5 feet bgs). However, the two locations performed at the south end of the project area (B-7 and B-8) may have encountered Pleistocene San Pedro Formation marine deposits near the bottom of the boring. The findings from this study are generally consistent with those described in reports prepared by previous investigators that we reviewed for our preliminary geotechnical study(Fugro, 2013). 9 6R0 RMC Water and Environment M February 18,2013(Project No.04.61130008) 2.2.1 Artificial Fill (at) The soil borings for this project were advanced in paved roadway or shoulder areas. The pavement section generally consisted of asphalt concrete over granular base materials. In many cases the artificial fill materials existing beneath the pavement structural section were not readily distinguishable from the underlying alluvial sediments based on visual observations. However, there is a potential that the upper few feet of soil material beneath the pavement sections have been reworked and graded during road construction. With the exception of aggregate base, soils used as fill were likely derived from the underlying alluvial materials. Because it was difficult to differentiate the fill from the underlying alluvium in the project area, notations of and contacts between fill or alluvial soils shown on the logs of borings may vary from actual conditions encountered during construction. 2.2.2 Alluvium (Qal) Alluvial materials sampled in the soil borings consisted of layered coarse and fine- grained deposits. The coarse-grained, or granular, deposits generally consisted of medium dense to dense silty sand and clayey sand. Locally very loose to loose and dense silty sand and clayey sand with trace amounts of shell fragments, gravel ranging to about 2 to 3 inches in diameter, and organics (such as tree roots) were encountered. Fine-grained soils were encountered in drill holes B-4 and B-5 below a depth of about 5 feet, in B-1 between 15 and 20 feet, and in B-7 and B-8 at depths of about 30 feet (we note the fine-grained soils in B-7 and B-8 could be San Pedro Formation). The fine-grained soils generally consisted of medium stiff to very stiff fat clay, fat clay with sand, elastic silt with sand, and sandy lean clay. 2.2.3 Engineering Properties A summary of the general engineering parameters for the tested materials is provided below. • SPT N-values within the granular soils generally ranged from about 2 to greater than 50 blows per foot. Based on the field SPT N-value data, in our opinion, the consistency of the granular alluvium is variable and is generally: o Medium dense to dense within the portion of the alignment where open cut construction is planned, o Loose to dense within the portion of the alignment where pipe bursting is planned, • SPT N-values within the fine-grained soils generally ranged from about 4 to 10 blows per foot. Based on the field pocket penetrometer and SPT N-value data, in our opinion, the consistency of the fine-grained alluvium is variable and is generally medium stiff to stiff. 10 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) 02 • Moisture-density test results indicate dry unit weights ranging from 68 to 92 pounds per cubic foot (pct) on fine-grained samples, and 98 pcf to 127 pct on coarse- grained samples; with moisture contents ranging from about 27 to 74 on fine- grained samples, and 8 to 29 percent for tested coarse-grained samples. • One direct shear test was performed on selected sample of granular alluvium and resulted in a measured a peak friction angle of 39 degrees and peak cohesion of 300 pounds per square foot (psf). • Two compaction tests (ASTM D1557) were performed on selected samples to assess their compaction characteristics. The tests results indicate maximum dry densities of 111 to 131 pct and optimum moisture contents of 8.2 to 16.1 percent. • The results of the percent passing the No. 200 sieve range from about 61 to 96 percent on fine-grained samples, and from about 7 to about 49 percent on coarse- grained samples. 2.3 GROUNDWATER Review of the California Geologic Survey (CGS) Seismic Hazard Zone Report for the project area (formerly CDMG, 1997), indicates that the historic high groundwater level in the vicinity of the alignment is about 10 feet bgs. Groundwater was encountered during field exploration in six of eight soil borings at depths ranging from 12 to 25 feet bgs along the project alignment. We note that the groundwater depths indicated on our boring logs as well as those in data presented in our preliminary geotechnical report (Fugro, 2013) may not reflect seasonal, perched, or static groundwater conditions and that the actual groundwater level encountered during construction could be higher or lower than those noted herein. The invert depth of the pipeline is anticipated to range from about 8 to 25 feet below the existing ground. Considering the proposed invert depths and the groundwater conditions encountered in our borings, in our opinion, groundwater will likely be encountered in excavations required to install the proposed pipeline and construct the associated improvements. 2.4 EXISTING PAVEMENT STRUCTURAL SECTION Existing asphaltic concrete pavement thicknesses measured during this study ranged from 6.5 to 10 inches and the underlying base materials ranged from 6 to 24 inches at the locations explored. The thicknesses of the pavements and base measured at each of the soil boring location are presented in Table 2 below and on the logs of borings in Appendix A. 11 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) Table 2.

Our opinions regarding potential geologic hazards are based on the data obtained from this study, limited existing geotechnical data, and published data provided in CGS (1997, 2009), and the City of Newport Beach (2007). 2.5.1 Faults and Ground Rupture Potential The project site is located within a seismically active area and the potential exists for strong ground motion to affect the project during the design lifetime. In general, the primary effects will be those phenomena associated with shaking and/or ground acceleration. Those effects can likely be mitigated through appropriate design and construction procedures. The proposed pipeline alignment is not located within or cross an Alquist-Priolo fault rupture hazard zone, and no known active or potentially active faults cross the project alignment. The closest active fault is the Newport-Inglewood Fault Zone and that fault is located about Yz-mile southwest of the project site. Therefore, in our opinion, the potential for fault- related ground rupture to impact the proposed pipeline is considered to be low to very low. However, there is a potential for strong ground shaking to occur at the project site as a result of earthquakes occurring on local or regional faults. 2.5.2 Strong Ground Shaking The 2008 USGS Interactive Deaggregation web site (USGS, 2008a) was used to probabilistically estimate the potential for strong ground motion at the site. Latitude N33.6256° 12 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) and longitude W117.92760 was used as the input location for estimating the peak ground acceleration (PGA) and alluvial site conditions were assumed. Based on our evaluations, we estimate that a PGA for an event with a 10-percent probability of exceedance in a 50-year exposure period (i.e., a return period of about 475 years) is about 0.35g. Also, according to USGS (2008b), the mean moment magnitude is 6.64 at a distance of 18.1 km from the site. The shear wave velocity of the alluvium was assumed to be 270 meters per second consistent with the range of shear velocity provided in the 2010 California Building Code for Site Class D soils. 2.5.3 Liquefaction Potential Liquefaction is generally described as the sudden loss of soil strength because of a rapid increase in soil pore water pressures due to cyclic loading during a seismic event. In order for liquefaction to occur, three general geotechnical characteristics must be present: 1) groundwater must be present within the potentially liquefiable zone; 2) the potentially liquefiable soil must be granular and the grain size distribution should fall within a relatively specific range; and 3) the potentially liquefiable soil must be of low to moderate relative density. If those criteria are met and strong ground motion occurs, then those soils may liquefy, depending upon the intensity and cyclic nature of the strong ground motion. Liquefaction that produces surface effects generally occurs in the upper 40 to 50 feet of the soil column, although the phenomenon can occur deeper than 100 feet. The CGS (1997) indicates that the majority of the project area is classified as being outside the area which is susceptible to liquefaction. However, groundwater and soil materials considered susceptible to liquefaction were encountered in our explorations. Soil borings B-6, B-7, and B-8 in the southern end of the project area encountered loose to medium dense granular soil below the groundwater level. We note that blowcount measurements obtained below the groundwater level using hollow-stem auger drilling methods can be affected or impacted by flowing sand conditions. However, our findings were consistent with those reported in Law/Crandall (1997) as discussed in our preliminary geotechnical report (Fugro, 2013). Therefore, in our opinion, there is a potential for liquefaction to occur in the southern portion of the alignment. In addition, there is a potential for liquefaction to occur in other portions of the alignment below the depths explored for this study. 2.5.4 Seismic Settlement Seismic settlement can occur in dry cohesionless soils as a result of the rearrangement of soil particles and densification caused by the shaking. Settlement can also occur as a result of liquefaction occurring below the groundwater level. We anticipate that seismic settlement at the site would likely result from a combination of liquefaction-related settlement and densification of dry cohesionless soils (sand, silty sand, etc.) from earthquake shaking. Based on the sampler blow count data from our soil borings, we estimate that seismic settlements in the project area from a design-level earthquake (475-year return period) would likely be less than about an inch. 13 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) 2.5.5 Lateral Spreading Considering the absence of free faces near the proposed pipeline, the current soil and groundwater conditions and the estimated liquefaction hazard, in our opinion, the potential for lateral spreading appears to be low. However, the risk of lateral spreading would be greater if the groundwater level was to rise in the future to within about 10 feet of the ground surface. Therefore, the risk of lateral spreading should not be considered nonexistent. 2.5.6 Tsunami /Flooding The project site lies adjacent to Newport Bay at an elevation of between about +35 feet to +85 and the potential for flooding to impact the project area is small. If considered a potential hazard, flooding should be evaluated by the project's civil engineer. The project area is in close proximity to the ocean however, the mapped tsunami inundation area (CGS, 2009) does not extend into the project area indicating that the potential tsunami hazard can be considered low. 3.0 RECOMMENDATIONS 3.1 GENERAL The geotechnical conditions in the project area were evaluated from the soil borings excavated for this study and from our review of existing geotechnical data as referenced herein. Geotechnical engineering recommendations for the project generally address the open cut portions of the pipeline and the trenchless or pipe bursting construction. Geotechnical conditions within the alignment primarily consist of interlayered medium dense to dense coarse- and medium stiff to stiff fine-grained alluvial or marine terrace materials as sampled in the soil borings. Groundwater was encountered at depths ranging between 12 and 25 feet (bgs) in six of the eight borings advanced for this study. Data reported in CGS (1997) is generally consistent with data from our study and suggests that historic high groundwater may be within about 10 feet of the ground surface. 3.2 EXCAVATIONS 3.2.1 Excavation Conditions The earth materials encountered in the soil borings excavated for this study consist primarily of interlayered silty sand and clayey sand. Fat clay soils were encountered in borings B-4 and B-5 and to a lesser extend in borings B-1, B-7, and B-8. In our opinion the granular soils are susceptible to caving. Therefore, appropriate shoring or laying back of trench walls should be utilized to reduce the potential for caving of trench excavations, access pits, and manhole excavations. 14 6R0 RMC Water and Environment M February 18,2013(Project No.04.61130008) 02 Based on our observations during drilling, we anticipate that conventional heavy grading equipment in good working order should be capable of excavating the earth materials encountered along the alignment. However, smaller equipment may be necessary where working space is limited. 3.2.2 Trench Subgrade and Stabilization Depending on the subgrade moisture conditions, groundwater levels at the time of construction, and construction activities near the bottom of the excavation, localized unstable or pumping subgrade conditions could be encountered. If pumping subgrade conditions are encountered, measures should be taken to stabilize the trench subgrade prior to placing pipe bedding or fill material. In addition, the excavations should be protected against rainwater and surface water runoff, and efforts should be made to maintain a dry, workable trench subgrade. In addition to overexcavation for pumping/unstable subgrade, additional overexcavation may be required below the proposed trench bottom to remove loose, soft, or unsuitable materials. The contractor, after considering input from the design engineer, geotechnical engineer, and owner, should be responsible for design and implementation of trench subgrade stabilization techniques. Some methods that have been used successfully to stabilize trench subgrade consist of: • Rock stabilization. The exposed unstable subgrade can be excavated and a geotextile fabric or biaxial geogrid can be placed along the excavation bottom and covered with at least 1 foot thick of compacted processed miscellaneous base (PMB) conforming to the requirements of Section 200-2.5 of the Standard Specifications for Public Works Construction (i.e. Greenbook 2003 edition). One- inch crushed gravel can be used in lieu of PMB; however, a layer of non-woven filter fabric (such as Mirafi 180N) should be placed over the gravel to separate the gravel from the overlying fill. Trench plugs should be provided to prevent lateral migration of water through the gravel stabilization layer. • Controlled Lean Slurry Mix. The exposed unstable subgrade can be overexcavated and replaced with controlled lean slurry mix (or 2-sack sand-cement slurry). On the basis of our past experience with unstable trench subgrade conditions, the placement of about 1 foot of gravel may be required to provide subgrade conditions that are suitable for the placement of pipe bedding and pipe zone backfill material. PMB materials used for stabilization should be compacted to a minimum of 90 percent relative compaction as determined by American Society for Testing and Materials (ASTM) D1557. Gravel used for stabilization should be wheel-rolled or vibrated in place until no reduction in volume is observed. Filter fabric materials should encapsulate the gravel stabilization layer. 15 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) 3.2.3 Dewatering Groundwater was encountered at 12 to 25 feet during drilling at the exploration advanced for this study and we understand that the historic high groundwater is about 10 feet bgs. We recommend that provisions for dewatering be incorporated into the project documents. The dewatering system used for the project should be designed, installed and maintained by an experienced company specializing in groundwater dewatering systems and the system be capable of lowering the groundwater surface to a depth of at least 3-feet below the required depth of excavation. Groundwater levels should be maintained below any point on the excavated surface (defined by the elevation of any overexcavated surface) and should provide excavation sidewalls free of groundwater seepage. Excavations for the project should not be made until it can be confirmed or demonstrated that the groundwater level has been lowered as required. Dewatering operations will require permitting in accordance with National Pollutant Discharge Elimination System (NPDES) regulations and possibly other local permits. 3.3 OPEN CUT CONSTRUCTION AND EXCAVATIONS 3.3.1 Trenching and Temporary Excavations Excavations more than 4 feet deep should be sloped, shored, or shielded in accordance with federal and state standards, project specifications, and safe construction practices. The contractor is responsible for providing and maintaining safe excavations, according to Occupational Safety and Health Administration (OSHA) regulations. In areas where the right-of-way is of sufficient width, temporary excavations could potentially be laid back. Fat clay and sand with varying amounts of silt, clay and gravel (OSHA Type C soils) were encountered in the soil borings. Therefore per OSHA's 29 CFR Part 1926, unsupported excavations in these soils that are free from groundwater seepage should be sloped no steeper than 1.5(h):1(v). In addition, flatter slopes may be warranted depending on exposed soil conditions. Temporary excavations should be monitored for stability during construction and be modified, if necessary. Excavations lacking adequate sidewall support could move or become unstable and result in damage to existing improvements and utilities adjacent to the pipeline trench or excavations. The use of unshored excavations will limit traffic access near the top of temporary slopes. Where there is insufficient width or where other factors would prohibit the use of temporary construction slopes, an excavation shoring system will likely be required. Based on our discussion with the project team, we understand limited space will be available for construction on this project and vertical trenches will be required. The selection, design, and installation of any shoring system needed for the project should be made by the contractor, in accordance with OSHA regulations and good construction practice and pipe manufacturer's recommendations. 16 6R0 RMC Water and Environment 1111�� February 18,2013(Project No.04.61130008) Trench box-type shoring systems can be used to provide for the safety of personnel working in the relatively shallow excavations (generally less than about 20 feet). However, because a space between the excavation side wall and the trench box is required for installation, trench boxes are usually not placed in contact with the soil and do not provide for stability of the side walls. This allows the side walls to deform, slump, ravel or erode to fill the initial space between the trench box and the recently excavated side walls. Movement, slumping, or erosion of the soil from the side wall can potentially result in distress to pavements, adjacent structures, or adjacent utilities and could make subsequent removal of the trench box difficult. Because of these issues, in our opinion, care should be taken when using trench box- type shoring systems especially in areas where utilities or critical surface improvements exist proximal the excavation. Where trench boxes are used, the contractor should take measures to fill the initial space between the side wall and the box and use caution when removing the box. Backfill should be placed in stages as the boxes are removed from the excavation. Trench box must be kept above the pipe zone or the pipe zone slurried as the shields are raised. In areas where ground movements from excavations need to be small or cannot be tolerated, more robust shoring systems will be required. Those systems could potentially consist of typical cantilevered and braced sheet piling (push in type), cantilevered soldier beam and lagging/plate systems. Other systems can be used such as cantilevered or braided auger cast or jet grouted secant pile walls, slurry diaphragm walls, or cement deep soil-mixed walls. However, those systems typically remain in-place following construction. Lateral pressures applicable for the design will depend on the type of shoring system selected by the contractor, surcharge loads due to construction equipment and traffic, and any dewatering methods that are used. The following geotechnical engineering parameters are provided for consideration in the design of temporary shoring and access pits. Fugro can provide additional guidance for the design of temporary shoring after the contractor has selected the type of shoring to be used for the project. The contractor should review those parameters during design and construction to evaluate whether the parameters are appropriate for the design and provide additional testing, exploration, and or evaluation, as needed. Table 3.

If this setback is not available, then surcharge loading on the shoring will need to be included. This is a general guideline and may need to be modified in the field for specific geotechnical conditions. However, if local soil conditions create a sidewall-stability hazard, the contractor should consult with a geotechnical engineer to evaluate alternative minimum distances needed between the edge of the excavation and construction equipment, vehicle traffic, and stockpiled materials, so that the potential for sidewall instabilities can be minimized. In areas adjacent to shored excavations, surcharge loading from equipment and materials should be considered in the design of the temporary shoring. 3.4 TRENCHLESS CONSTRUCTION 3.4.1 Pipe Bursting We understand that trenchless construction methods may be used for pipeline upsizing near the bottom of the system (MH-145 to MH-025). Recommendations for temporary excavation provided above are applicable to access pit excavations. Pipe bursting has effects on the surrounding environments, including potential ground displacement especially in areas with inadequate or minimal soil cover. The potential for ground displacement depends primarily on: degree of upsizing, type and compaction level of the existing soil around the pipe, and depth of bursting (USACE, 2001). In the area where pipe bursting is proposed, the soils are coarse- grained or granular deposits generally consisting of loose to dense silty and clayey sand. These conditions were discussed with pipe bursting contractor IPR-West/Repipe (Personal Communication, January 17, 2014). IPR-West/Repipe indicated that pneumatic methods are problematic in sandy soils because the hammer action can cause settlement around the pipezone. Static bursting methods they stated, although slower and less productive, are often better suited for sandy soils; and pipe bursting is generally good for clayey soils, not ideal for sandy soils, and bad for rock. Review of the subsurface exploration data in the southern end of the proposed project area indicate silty and clayey sand with varying amounts of gravel to depths of about 31.5 feet. Historical explorations presented in our preliminary report (Fugro, 2013) also make note of a small amount of gravel (10%) and few cobbles to 6 inches in diameter. Groundwater was encountered during our recent field exploration at elevations above or near the pipeline invert. 3.4.2 Monitoring of Trenchless Construction Ground settlement or heaving could occur from excavations and pipe bursting operations. The proposed equipment, procedures, and the contractor's quality control procedures should be selected and the work performed in a manner that does not adversely 18 6R0 RMC Water and Environment M February 18,2013(Project No.04.61130008) impact the existing road surface or other infrastructure. As such, care should be taken to determine required ground deformation tolerances and develop procedures for construction operations for the various types of infrastructure above or adjacent to the work. The owners of the existing infrastructure may have construction constraints and/or requirements for the type of work proposed, and special provisions pertaining to construction methods and monitoring should be anticipated. The project specifications should require the contractor to submit a detailed plan of the monitoring program and pipe bursting procedures. Although unlikely considering the depth of cover above the pipe, if deformations from pipe bursting are detected, modifications to the work may be required to prevent excessive settlement or heave. If the heave or settlement exceeds acceptable levels, then mitigation and repair to the roadway, sidewalks or other improvements, may be required. 3.5 FILL MATERIALS 3.5.1 General Fill Fill, backfill, and embankment materials shall be suitable selected or processed clean, fine earth, rock, or sand, and free from grass, roots, brush, or other vegetation; contamination; or deleterious material. On the basis of the data from our explorations and review of previous soil borings, we estimate that a large percentage of the on-site soils in the upper reaches of the proposed project area where open-cut construction techniques are planned should meet the above criteria for general fill. 3.5.2 Imported Fill Imported fill materials may be used for general fill or select fill (bedding, pipe zone, trench backfill), provided that the imported fill satisfies the requirements for its intended use. Imported fill material should be evaluated by the geotechnical engineer to verify suitability for its intended use. 3.5.3 Bedding and Pipe Zone Materials Bedding and pipe zone backfill consist of material placed beneath and around the pipe. Unless OCSD or other agencies have more stringent requirements, soil materials used for pipe bedding should consist of imported granular soils with a sand equivalent of at least 30 and should meet the Greenbook requirements for pipe bedding and pipe zone backfill. Backfill should be placed in loose lift thicknesses no greater than 8 inches and mechanically compacted. Bedding and pipe zone backfill should be compacted to at least 90 percent relative compaction as determined from ASTM D1557. Bedding should extend at least 12 inches below the pipe and extend at least 12 inches above the pipe. 19 6R0 RMC Water and Environment M February 18,2013(Project No.04.61130008) 02 The trench width should be sufficient to allow compaction equipment to operate between the pipe springline and trench wall. We recommend that jetting or flooding of pipe zone materials not be allowed. 3.5.4 Trench Backfill Material Trench backfill consists of material placed above the pipe zone backfill and, in paved areas, extends to the base of the pavement structural section. Unless OCSD or other agencies have more stringent requirements, soil materials used for pipe trench backfill should consist of granular soils with a sand equivalent of at least 20 and should meet the Greenbook requirements for trench backfill. Alternatively, 2-sack sand cement slurry can be used for trench backfill, if approved by RMC and the OCSD. The upper 12 inches of trench backfill placed below the asphalt concrete pavement should consist of asphalt base course (ABC) followed by 2.5 feet compacted sub base material compacted to 95 percent relative compaction.. Placement of this material should be in accordance with Standards of Orange County Sanitation District (Standard Drawing S-010) as appropriate, and Greenbook specifications. In general, backfill should be moisture conditioned to within 2 percent of optimum, placed in loose lift thicknesses no greater than 8 inches, and mechanically compacted. Trench backfill should be compacted to at least 90 percent relative compaction, as determined from ASTM D1557. We recommend that jetting or flooding of pipe trench backfill materials not be allowed. We anticipate that some of the onsite granular soils within the open-cut portion of the project will meet the minimum sand equivalent requirements for trench backfill. However, some selective screening and processing of the soils may be required. 3.5.5 Backfill and Other Loads on Pipes Backfill loads on the pipes will depend on the pipe type (i.e., rigid or flexible), geometrical conditions (embankment or trench configuration), depth of backfill, and on the characteristics of the backfill and in situ soils. For design purposes, we recommend that a total unit weight of 125 pcf be used to estimate backfill loads. Appropriate pipe design references should be consulted to determine other pipe design parameters. Other external loads on the pipes come from construction activities, loads related to traffic, or other post-construction land uses. The pipes should be designed to resist the imposed loads with an added factor of safety and for an appropriate limiting deflection. The pipe may be subjected to surcharge pressure line loads and point loads due to construction activities and traffic, and those loading conditions should also be considered in the design of the pipe. 20 6R0 RMC Water and Environment Is February 18,2013(Project No.04.61130008) 02 3.5.6 Pipeline Uplift Considerations Portions of the proposed pipelines may be subjected to hydrostatic uplift pressure from groundwater when the pipelines are empty. We recommend that the potential for uplift of the pipelines be considered. Because shallow groundwater conditions have been reported in the past, we recommend that the depth to groundwater be assumed at a depth of about 10 feet bgs when evaluating pipeline uplift. Uplift resistance can be provided by the weight of soil above the pipe and the soil frictional resistance. The weight of soil above the pipeline should be assumed to be 125 pcf for soil above the water level and 60 pcf (buoyant weight) for soils below the ground water level. The ultimate frictional resistance of a rectangular soil prism (soil-soil interface) for saturated (undrained) conditions can be assumed to be 15 pounds psf per foot of depth. 3.5.6 Modulus of Soil Reaction Flexible and semi-rigid pipes are typically designed to withstand a certain amount of deflection from the applied earth loads. Those deflections can be estimated with the aid of equations developed by Howard (1995). We suggest an E'-value of 2,500 pounds per square inch for project design. The E'-value is for a combined trench/pipeline system that includes a minimum of 24 inches of compacted pipe-zone material around the pipeline and is applicable for use with the Reclamation equation (Howard, 2006). 3.6 VAULTS AND MANHOLES 3.6.1 Allowable Bearing Capacity and Static Settlement We anticipate proposed vaults and manholes will consist of below-grade structures with concrete walls and concrete foundations. The foundation level for the structures is anticipated to be about 10 to 25 feet below the existing ground surface. On the basis of our experience with similar structures, in our opinion, the proposed vaults can be supported on concrete mats founded on the undisturbed native alluvium, or to at least 90 percent relative compaction, as determined from ASTM D1557, if disturbed. We recommend a maximum allowable (net) bearing pressure of 2,000 psf be used for the design of the proposed foundations. The maximum allowable bearing pressure is considered applicable to a mat-type foundation slab and can be increased by one-third when considering short-term wind or seismic loads. We estimate that total static settlements of the proposed manholes and vault structures will be less than 1 inch. 3.6.2 Uplift Resistance Vaults and manholes could be subject to uplift forces given the groundwater conditions observed along the alignment. The magnitude of the uplift pressure acting on the vault Will depend on the groundwater level at the structure location. Based on the explorations conducted for the project and on historic data, groundwater levels of 10 feet bgs should be considered. 21 6R0 RMC Water and Environment ON February 18,2013(Project No.04.61130008) Although unlikely, we cannot rule out the possibility of groundwater conditions changing over time due to land use changes, groundwater pumping, or seasonal conditions. In our opinion, vaults, manholes, and piping should be checked for uplift assuming that groundwater is present at a depth of about 10 feet bgs. For this scenario, we recommend a minimum factor of safety of at least 1.25 be used. The uplift forces may be resisted by: 1) the gross weight of the structure; 2) friction between soil interfaces for structures with footing extensions; and 3) the weight of soil located above footing extensions beyond the outside walls of the structures. The frictional resistance can be estimated to increase linearly with depth. We recommend an ultimate frictional resistance of 35 psf per foot of depth be used for soil interfaces above the groundwater level. For soil below the groundwater level, the rate of increase in the frictional resistance should be assumed at 15 psf per foot of depth. If footing extensions are used, the potential wedge of soil providing resistance to uplift should be considered to be bounded by the outside walls of the structure and a vertical plane extending up from the edge of the footing extension. A unit weight of 125 pcf should be used to estimate the weight of unsaturated soil above the footing extensions. For soils below the groundwater level, a unit weight of 60 pcf should be used. 3.6.3 Lateral Earth Pressures Static Earth Pressures. Retaining structures that are unable to rotate or deflect laterally (e.g., restrained below-grade or basement walls) are referred to as restrained or rigid walls. We have assumed that the below grade walls for vaults and manholes Will be rigid and should be designed for at-rest conditions. Lateral earth pressures (equivalent fluid weights) for design of the proposed vault and miscellaneous walls are provided in Table 4 - Equivalent Fluid Weights for Developing Lateral Earth Pressures. Table 4. Equivalent Fluid Weights for Estimating Lateral Earth Pressures Equivalent Fluid Weights(pounds,pcf) Backfill Slope At-Rest Conditions Inclination Behind Wall Drained Undrained Level Granular Backfill 60 95 The equivalent fluid weight for undrained conditions accounts for the buoyant unit weight of soil and includes the unit weight of water. In general, we recommend that undrained conditions be assumed below a depth of 10 feet unless perimeter subsurface drainage devices are provided. If the drainage devices are constructed, drained conditions can be assumed above the drainage devices and undrained conditions should be used below that level. 22 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) 02 The estimated equivalent fluid pressures should be applied to a vertical plane passing through the backmost extension of the wall. The height of the vertical plane should extend from the point where the vertical plane intersects the ground surface down to the elevation of the lowest retaining wall foundation. We recommend materials placed as backfill adjacent to the manholes or vaults consist of onsite or imported granular soil with less than 30 percent passing the No. 200 sieve and have a sand equivalent of at least 20. Where manholes are backfilled with slurry, the slurry should be placed in stages to avoid creating uplift for the manhole. The manhole should be designed for the equivalent fluid weight of slurry, approximately 130 pcf. 3.6.4 Sliding and Passive Resistance Sliding resistance generated through a concrete-on-soil interface may be computed by multiplying the total dead weight structural loads by the coefficient 0.35. Passive resistance developed from lateral bearing of shallow foundation elements bearing against level compacted fills or undisturbed native soils can be determined using an equivalent fluid weight of 350 pcf for drained conditions and 150 pcf for undrained conditions (i.e. below the groundwater level). Frictional resistance and passive pressure may be used together without reduction in evaluating foundation sliding. A minimum factor of safety of 1.5 is recommended for foundation overturning and sliding. 3.7 SOIL CHEMISTRY AND CORROSION 3.7.1 Test Results One soil sample obtained from B-3 was provided to Cooper Testing Laboratories for resistivity, pH, chloride, and sulfate testing. Test results are presented below in Table 5. The laboratory test report is included in Appendix B. Table 5. Summary of Chemical Test Results Drill USCS Classification Depth Sulfate Chloride Resistivity pH Hole (feet) (percent) (ppm) (ohm-cm) B-3 SC 10 0.0067 484 789 7.9 3.7.2 Corrosion and Cement Considerations The resistivity values suggest that existing onsite sandy soil materials are corrosive to underground steel. If applicable, the test results should be evaluated by a corrosion engineer to determine how underground utilities should be protected from corrosion. 23 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) The cement type should be selected with consideration of the sulfate content of the tested soils. Available sulfate content data suggest that, per Table 4-3-1 of ACI 318 (2005), Type II cement can be used for concrete that will be in contact with onsite soils. 4.0 LIMITATIONS 4.1 REPORT USE This letter report has been prepared for the exclusive use of RMC Water and Environment and the Orange County Sanitation District for the design and construction of the proposed District 6 Trunk Sewer Relief Project in Newport Beach, California. The findings, conclusions, and recommendations presented herein were prepared in accordance with generally accepted geotechnical engineering practices of the project region. No other warranty, express or implied, is made. Although information contained in this report may be of some use for other purposes, it may not contain sufficient information for other parties or uses. If any changes are made to the project as described in this report, the conclusions and recommendations in this report shall not be considered valid unless the changes are reviewed and the conclusions and recommendations of this report are modified or validated in writing by Fugro. 4.2 POTENTIAL VARIATION IN SUBSURFACE CONDITIONS Earth materials can vary in type, strength, and other geotechnical properties between points of observations and exploration. The soil borings performed for this study were spaced along the proposed pipeline alignment, as shown on Figure 2 and Chart 1. Therefore, there is a potential for variation in the consistency, density, and strength/hardness of the materials. There is also potential for oversized materials (greater than 8 inches in diameter), perched water, zones of poorly consolidated soils to be present, or other conditions not indicated in the logs of borings. Additionally, groundwater and soil moisture conditions also can vary seasonally or for other reasons. Moreover, we do not and cannot have a complete knowledge of the subsurface conditions underlying the site. If significant variation in the geologic conditions is observed during grading, we recommend that the geotechnical engineer, in conjunction with the project designer, evaluate the impact of those variations on the project design. The conclusions and recommendations presented in this report are based on the findings at the points of exploration, interpolation, and extrapolation of information between and beyond the points of observation, and are subject to confirmation (to the extent possible) based on the conditions revealed during construction. 4.3 HAZARDOUS MATERIALS We performed Organic Vapor Meter (OVM) readings during the collection of soil samples, however, this report does not provide information regarding the presence of hazardous/toxic materials in the soil, surface water, groundwater, or atmosphere. 24 6R0 RMC Water and Environment February 18,2013(Project No.04.61130008) 4.4 LOCAL PRACTICE In performing our professional services, we have used generally accepted geologic and geotechnical engineering principles and have applied the degree of care and skill ordinarily exercised under similar circumstances by reputable geotechnical engineers currently practicing in this or similar localities. No other warranty, express or implied, is made as to the professional advice included in this report. 4.5 PLAN REVIEW We recommend that Fugro be provided the opportunity to review and comment on the geotechnical aspects of any project plans and specifications prepared for the project before they are finalized. The purpose of that review will be to evaluate if the recommendations in this report have been properly interpreted and implemented in the design and specifications. 4.6 CONSTRUCTION MONITORING Users of this report should recognize that the construction process is an integral design component with respect to the geotechnical aspects of a project, and that geotechnical engineering is inexact due to the variability of natural and man-induced processes, which can produce unanticipated or changed conditions. Proper geotechnical observation and testing during construction is imperative in allowing the geotechnical engineer the opportunity to verify assumptions made during the design process. Therefore, we recommend that Fugro be retained during pipeline construction to observe compliance With project plans and specifications and to recommend design changes, if needed, in the event that subsurface conditions differ from those anticipated. 25 6R0 RMC Water and Environment M February 18,2013(Project No.04.61130008) 5.0 REFERENCES American Concrete Institute (2005), Building Code Requirements for Structural Concrete and Commentary 318-05.

Prater Orange County Sanitation District 10844 Ellis Ave. f Fountain Valley,CA 2708 Re: Award Protest Statement of W.A.Rasic Construction Company, Inc.; Project No. 6-17,District 6 Trunk Sewer Relief M Dear Mr. Prater: Please consider this to be the Award Protest Statement of W.A. Rasic Construction Company,Inc. ("Rasic") in compliance with the instruction to bidders on the above project. Rasic was the second lowest bidder. Rasic protests the award of the project to Charles King Company,Inc. ("King") for the reasons outlined below. First,Addendum No. 3 in Section BF-4 PERFORMANCE HISTORY AND FINANCIAL RESOURCES (attached for reference)required bidders to demonstrate experience with pipe bursting installation. In this regard,the addendum provided: "The Bidder shall list at least one(1)pipeline project with a public owner completed within the last eight(8)years involving installation of minimum 12-inch diameter pipe via pipe bursting for a length of 1,000 feet or more. Bidder's listed projects shall be similar in nature, scope, complexity and cost to this Project.For each listed project, Bidder shall include the project name and location, Bidder's role, description of work, length, diameter and material of qualifying pipe, final contract value, contract completion date,contact name(s) and phone number(s). The Bidder must submit this information with its Bid."(BF-4 A.3.) In an attempt to satisfy this minimum experience requirement, King identified the Bristol Street Sewer Replacement Phase H project owned by the Costa Mesa Sanitary District. Rasic was a bidder on the Bristol Street Project. Despite King's misrepresentation that the length was longer, 4150 Long Beach Boulevard, Long Beach, CA 90807 - 562-928-6111 - fax: 562-928-7339 - www.warasic.com state contractor's license#A368761 the Bristol Street Project was for the construction of only 703LF of pipe. Attached here is a copy of the Bristol Street specification and schedule of work items. Bid item g is the relevant item. Moreover,Addendum No. 3 required the bidders to identify whether or not they self- performed the work"or directly supervised a Subcontractor(s)"who performed the work. King indicated that it directly supervised the work on the Bristol Street Project, suggesting that it was the prime contractor. Attached hereto is a copy of the prime contract on the Bristol Street project which indicates that the prime contractor was Repipe California,Inc.,not King. Whatever role King may have had on the Bristol Street project,it is clear that King does not meet the required experience for pipe bursting. Addendum 3 provides that if a bidder cannot demonstrate the required experience,"its Bid shall be deemed nonresponsive." There is a strong public policy interest in assuring that the Sanitation District does not run afoul of the competitive bidding requirements.' "The provisions of statutes, charters and ordinances requiring competitive bidding in the letting of municipal contracts are for the purpose of inviting competition, to guard against favoritism, improvidence, extravagance, fraud and corruption, and to secure the best work or supplies at the lowest price practicable...:. Kaiima/Rav Wilson v. Los Angeles County Metropolitan Transportation Authority (2000) 23 Cal.4° 305, 314. Here, the Sanitation District, in requiring each bidder to meet certain experience qualifications, acted to shrink the pool of potential bidders. No doubt other potential bidders who, like King, did not have the required experience rightly decided against submitting a bid for the project. It would run afoul of the competitive bidding requirements to on the one hand shrink the pool of potential bidders and then on the other hand award the contract to a contractor not meeting the minimum requirements set forth in the instructions to bidders. The specification here clearly requires the disqualification of a contractor not meeting the experience qualification. Demand is made that the project be awarded to Rasic, the lowest responsive and responsible bidder. I declare under penalty of perjury under the laws of the state of California that I am informed and believe that the foregoing is true and correct. Sincerely, WATER 1-1 C 'California law requires public construction projects to be awarded to the lowest responsible bidder.

Rasic Construction Company, Inc. ("Rasic"), concerning the award of the referenced project to Charles King Company("CKC"). Apparently disappointed that its bid came in higher than CKC's, and for its own benefit rather than the public's, Rasic seizes on an immaterial bid deviation in an attempt to take the project for itself at an increased cost to taxpayers. The number of lineal feet in pipe bursting experience was irrelevant to the determination of the low bidder and did not give CKC a competitive advantage. As set forth in detail below, CKC is the lowest responsive, responsible bidder for the project and the Orange County Sanitation District ("District")should proceed with its planned award of a contract to CKC. 1. Background On July 26, 2016, the District received bids for the project. CKC submitted a bid to construct the project for$3,699,301.00. Included in CKC's bid is$138,000.00 for a subcontractor, Mocon Corp. ("Mocon"), to perform the pipe-bursting work. Mocon is one of the preeminent pipe- bursting subcontractors in Southern California and has performed thousands of feet of pipe bursting operations on publicly owned projects. As detailed on the enclosed reference, Mocon has performed pipe bursting work in excess of 1,000 feet on at least seven publicly owned projects. (Tab 1.) In addition, CKC, as subcontractor to RePipe, participated in all pipe bursting activities related to the the installation of more than 700 feet of 12" pipe on the Bristol Street Sewer Replacement Phase II project("Bristol Project")and successfully completed pipe bursting operations on other publicly owned projects throughout California. CKC is fully trained in the proper methods and procedures to perform the requisite pipe bursting operations on this project. (Tab 2.) With its total bid of$3,699,301.00, CKC submitted the lowest bid for the project. Rasic was the second lowest bidder, with a bid price of$5,664,100.00, which is $1,964,799.00 higher than CKC's bid. 1 2. Competitive Bidding Laws Are For The Benefit Of The Public Not Private Interests Courts have consistently found that California's public bidding statutes are intended to benefit the taxpaying public, not private bidders. The principle was stated succinctly in Eel River Disposal and Resource Recovery, Inc. v. Humboldt(2013)221 Cal.AppAth 209, 232: "[s]tatutes and ordinances that authorize or require competitive bidding in the letting of public contracts ordinarily serve the purpose 'of inviting competition, to guard against favoritism, improvidence, extravagance, fraud and corruption, and to secure the best work or supplies at the lowest price practicable."' (Domer Electric, Inc. v. City of Los Angeles(1994) 9 Cal.4th 161, 173.) Such measures "'are enacted for the benefit of property holders and taxpayers, and not for the benefit or enrichment of bidders, and should be so construed and administered as to accomplish such purpose fairly and reasonably with sole reference to the public interest. These provisions are strictly construed by the courts, and will not be extended beyond their reasonable purpose. Competitive bidding provisions must be read in the light of the reason for their enactment, or they will be applied where they were not intended to operate and thus deny municipalities authority to deal with problems in a sensible, practical way.' [Citation.] [Laws] requiring competitive bidding are not to be given such a construction as to defeat the object of insuring economy and excluding favoritism and corruption. [Citations.]" (ibid.) Rasic wants to turn this principle on its head. Without establishing any possibility of"favoritism, improvidence, extravagance, fraud [or] corruption," Rasic simply seeks to exploit CKC's immaterial deviation in qualifications for an extremely small portion of the work on the project, solely for Rasic's own benefit. Rasic does not even attempt to make an argument of how the public would benefit from an award to Rasic, nor could it. "It certainly would amount to a disservice to the public if a losing bidder were to be permitted to comb through the bid proposal or license application of the low bidder after the fact, [and] cancel the low bid on minor technicalities, with the hope of securing acceptance of his, a higher bid. Such construction would be adverse to the best interests of the public and contrary to public policy.' [Citation.]" (Ghilotti Construction Co. v. City of Richmond, (1996)45 Cal.App.4th 897, 908 -909.) With a bid price nearly$2,000,000.00 higher than CKC, the only party to benefit from a rejection of CKC's bid is Rasic. 3. The District May Waive Minor Bid Irregularities "A basic rule of competitive bidding is that bids must conform to specifications, and that if a bid does not so conform, it may not be accepted. [Citations.] However, it is further well established that a bid which substantially conforms to a call for bids may, though it is not strictly responsive, be accepted if the variance cannot have affected the amount of the bid or given a bidder an advantage or benefit not allowed other bidders or, in other words, if the variance is inconsequential. [Citation.]" (Ghilotti, supra, 45 Cal.App.4th at p. 904 [citations omitted].) As a matter of law, the District has the right to reject bids or to waive immaterial or inconsequential errors. "An agency has discretion to waive immaterial deviations from bid specifications and may accept the bid under certain conditions. The point of discretion is that the agency may properly act in either direction. It may waive or refuse to waive such deviations." (MCM Const. Inc. v. City and County of San Francisco(1998)66 Cal.App.4th 359, 374.) Here, the District expressly reserved to itself this right. Specifically, section IB-18(8)of the IFB states: OCSD may "waive any errors or informalities in any Bid...." "The question '"[w]hether in any given case a bid varies substantially or only inconsequentially from the call for bids is a question of fact. ' [Citation.]" (Ghilotti, supra, 45 Cal.AppAth at p. 906, 53 Cal.Rptr.2d 389.) As reflected in the authority summarized above, "[t]o be considered inconsequential, a deviation must neither give the bidder an unfair competitive advantage nor otherwise defeat the goals of insuring economy and preventing corruption in the public contracting process."' (Id. at p. 900, 53 Cal.Rptr.2d 389.) "These considerations must be evaluated from a practical rather than a hypothetical standpoint, with reference to the factual circumstances of the case. They must also be viewed in light of the public interest, rather than 2 the private interest of a disappointed bidder." (Bay Cities Paving & Grading, Inc. v. City of San Leandro(2014)223 Cal.App.4th 1181, 1189.) With the principles enunciated above in mind, it is obvious that the District has the right, and the factual foundation, to conclude that the 300-foot discrepancy in experience related to pipe bursting operations is inconsequential. The discrepancy did not give CKC a competitive advantage or"otherwise defeat the goals of insuring economy and preventing corruption in the public contracting process." 4. CKC's Bid Deviation Is Immaterial And Did Not Give CKC A Competitive Advantage CKC's bid is responsive on all counts. The District's factual inquiry regarding pipe bursting experience relates to contractor experience and ability to perform the project. Contractor experience is irrelevant to whether the bid itself meets the technical requirements of the IFB. Here, the deviation of CKC's identified work experience for pipe bursting operations is immaterial. First, the pipe bursting scope of work constitutes 3.7 percent of CKC's total bid, and is not a significant portion of the work on the project. Second, there is a small difference between 700 and 1,000 feet; both amounts demonstrate significant experience in performing pipe bursting operations on publicly funded projects. Finally, both CKC and its subcontractor, MOCON, have experience sufficient to demonstrate they are capable of performing the work in a satisfactory manner. Summarily, whether the project cited by CKC for work experience was a project of 700 or 1,000 feet, is immaterial to the responsiveness of the bid. Further, CKC's minor deviation in pipe bursting experience did not give it a competitive advantage over the other bidders on the project because it did not affect CKC's price. Rasic attempts to frame the deviation as giving CKC an advantage over some unspecified group of parties who may have wanted to bid the project but didn't. This position is unfounded. The bottom line is CKC's price was not affected by its citation of the Bristol Project as an exemplar of its pipe bursting experience and did not give CKC an advantage over Rasic or any other contractor that actually turned in a bid. Accordingly, the District should waive the immaterial deviation and affirm its award of the project to CKC as the lowest responsive and responsible bidder. 5. Conclusion Rasic's bid protest attempts to challenge the responsiveness of CKC's bid, but actually focuses on whether CKC is a responsible bidder, which it is. However, to the extent the District finds there is any merit to Rasic's responsibility challenge, the District is required to hold a hearing at which CKC can present evidence providing beyond a shadow of a doubt that it is responsible and qualified. There is no basis for Rasic's assertion CKC is not responsible. CKC is eminently qualified and, in the interest of the taxpayers, the District can and should waive wave the immaterial deviation and award the project to CKC.

Rasic Construction Garden Grove 4150 Long Beach Blvd. Huntington Beach Long Beach, CA 90807 Irvine SUBJECT: OCSD Response to W.A. Rasic Construction Award Protest Re: Project No. 8-17, District 6 Trunk Sewer Relief La Habra La Palma Los Alamitos This letter responds to the Award Protest filed by W.A. Rasic Construction (Rasic) dated August 23, 2016, protesting the Orange County Sanitation Newport Beach District's (OCSD) solicitation and bid evaluation process and recommendation for award of the above referenced project to Charles King Company, Inc. Orange (CKC). Placentia In summary, Rasic contests: 1.) CKC's demonstrated experience with the pipe Santa Ana bursting method of pipe installation; 2.) CKC's role on one of their listed projects demonstrating such experience; and, 3.)that OCSD, in requiring each bidder to Seal Beach meet certain minimum experience requirements as identified in the Invitation For Stant Bids (IFB), acted to"shrink"the pool of potential bidders. Tustin The Bid Forms, BF-4 PERFORMANCE HISTORY AND FINANCIAL RESOURCES, A. LIST OF CURRENT AND COMPLETED PROJECTS AND Villa Park EXPERIENCE REQUIREMENTS, was modified twice. The first modification County of orange was in Addendum No. 1 to replace the first paragraph in its entirety, and add the words "Bidder's role" in the third sentence of sub items A.1., A.2., and A.3. Costa Mesa Addendum No. 3 modified sub item A.3. by reducing the minimum diameter Sanitary District pipe from 15"to 12" as follows: Midway City "The Bidder shall list at least one (1) pipeline project with a public owner Sanitary District completed within the last eight (8) years involving installation of Irvine Ranch minimum 12-inch diameter pipe via pipe bursting for a length of 1,000 Water District feet or more. Bidder's listed projects shall be similar in nature, scope, Yorba Linda complexity and cost to this Project. For each listed project, Bidder shall Water District include the project name and location, Bidder's role, description of work, length, diameter and material of qualifying pipe, final contract value, contract completion date, contact name(s) and phone number(s). The Bidder must submit this Information with Its Bid." Our Mission: 7o protect public health and the environment by providing effective wastewater collection, treatment, and recycling. O,H\N SPNliq ii •9 2 f, Z iNF E Y\ Walter Rasic Page 2 of 3 Rasic alleges that CKC did not meet the minimum experience requirements for this item under two scenarios: 1.) CKC listed Bristol Street Sewer Replacement Phase II (Bristol) project for the construction of only 703LF of pipe via the pipe bursting method instead of 1,000LF as indicated on their Bid Form, and 2.)that CKC listed that it directly supervised the work, therefore suggesting it was the prime contractor when actually, the prime contractor was Repipe California, Inc. During the evaluation of bids, OCSD independently established that the Bristol project consisted of approximately 700LF of pipe bursting. OCSD also verified that CKC's other listed project, Various Locations Citywide Sewer Main Rehab, City of Camarillo, included approximately 400LF of pipe bursting. The requirement as stated above is for the Bidder to list"at least one (1) pipeline project...for a length of 1,000 feet or more." This item does not require each project to be 1,000 feet or more. This is distinctly different than item A. 2., which requires "...at least two (2) pipeline projects...for a length of 2,000 feet or more for each proiect." Added together, the total length is approximately 1,100 feet as verified by OCSD. Therefore, OCSD determined that the minimum length of 1,000 feet was met by CKC. Next, Rasic alleges that CKC "...indicated that it directly supervised the work on the Bristol Street Project, suggesting that it was the prime contractor'. OCSD will not engage in speculation whether or not this is true, and considers this irrelevant to making a determination of whether or not CKC met this requirement. However, OCSD did ensure that CKC met the standards required. The requirement states in the first paragraph of BF-4 A., "...Using the table below, the Bidder shall provide its list of projects to demonstrate that it has either self-performed or directly supervised a Subcontractor(s) on the following three (3) criteria below..." OCSD verified that that CKC did perform as a Subcontractor under Repipe on the Bristol project and self-performed the pipe bursting work, and verified that CKC self-performed the work on the listed City of Camarillo project. Therefore, OCSD determined that CKC met the bid requirement to either self-perform or directly supervise the pipe bursting work. Finally, Rasic alleges that OCSD limited the pool of potential bidders by requiring them to meet certain experience requirements as stated in the IFB. N � PH,igii •9 A J fCt�� iME J Walter Rasic Page 3 of 3 Pursuant to the Instructions to Bidders IB-29, a Solicitation Phase protest may be filed by any Bidder or Prospective Bidder (on solicitation, Interested Party) .who has reason to believe that a free and open competition has not taken place or that a particular specification or requirement is impractical, unduly restrictive, or ambiguous...by submitting a detailed Solicitation Protest Statement in accordance with the requirements ..." set forth in Section A of the Instructions. If Rasic believed that the experience requirements were impractical or unduly restrictive, it could have submitted such a protest statement; however, no Solicitation Protest Statement was submitted by Rasic or any other prospective bidder. Therefore, it is too late to challenge the bid requirements. OCSD takes seriously the need to follow all statutes, codes and ordinances in the solicitation of its contracts and to promote open, fair competition. In fact, to allow more potential bidders to meet the Bid requirements, in Addendum No. 3 OCSD reduced the minimum diameter size for the pipe bursting experience requirement from 15" in diameter to 12" in diameter. OCSD has carefully reviewed the bid submitted by Charles King Company, Inc. In accordance with statutory requirements and OCSD's procedures, and has determined that the bid submitted by Charles King Company, Inc. is responsive and responsible. OCSD reviewed the Rasic Award Protest and arguments raised therein protesting the award of Project No. 6-17 to Charles King Company, Inc. OCSD finds that the Award Protest Statement is without merit on both allegations of (1) not meeting the pipe bursting minimum length requirement and (2) Charles King Company, Inc.'s role on the Bristol project. Regarding the third allegation, OCSD finds that it does not comply with the requirements set forth in IB-29 for the submission of a Solicitation Phase Protest. OCSD will proceed to recommend award of the Project No. 6-17 to the lowest responsive and responsible Bidder, Charles King Company, Inc., at the Board of Directors meeting on September 28, 2016.
