Please review the current effective Flood Insurance Rate Maps(FIRMS)for the County of Orange(Community Number 060212),Maps revised March 21,2019 and Cities of Costa Mesa, Fountain Valley,Huntington Beach,Newport Beach,Santa Ana,and Westminster(Various community and map revision dates). Please note that the Cities of Costa Mesa,Fountain Valley, Huntington Beach,Newport Beach,Santa Ana,and Westminster,Orange County,California are participants in the National Flood Insurance Program(NFIP). The minimum,basic NFIP 2-A floodplain management building requirements are described in Vol.44 Code of Federal Regulations(44 CFR),Sections 59 through 65. A summary of these NFIP floodplain management building requirements are as follows: • All buildings constructed within a riverine floodplain,(i.e.,Flood Zones A,AO,AH,AE, and Al through A30 as delineated on the FIRM),must be elevated so that the lowest floor is at or above the Base Flood Elevation level in accordance with the effective Flood Insurance Rate Map. www.remegw Comment Letter 2 Kevin Hadden,Orange County Sanitation District Page 2 May 1,2019 • If the area of construction is located within a Regulatory Floodway as delineated on the FIRM,any development must not increase base flood elevation levels. The term development means any man-made change to improved or unimproved real estate, including but not limited to buildings,other structures,mining,dredging,filling, grading,paving,excavation or drilling operations,and storage of equipment or materials. A hydrologic and hydraulic analysis must be performed prior to the start of development,and must demonstrate that the development would not cause any rise in base flood levels. No rise is permitted within regulatory floodways. • All buildings constructed within a coastal high hazard area,(any of the"ll"Flood Zones as delineated on the FIRM),must be elevated on pilings and columns,so that the lowest horizontal structural member,(excluding the pilings and columns),is elevated to or above the base flood elevation level. In addition,the posts and pilings foundation and the structure attached thereto,is anchored to resist flotation,collapse and lateral movement due to the effects of wind and water loads acting simultaneously on all building components. • Upon completion of any development that changes existing Special Flood Hazard Areas, 2 A the NFIP directs all participating communities to submit the appropriate hydrologic and hydraulic data to FEMA for a FIRM revision. In accordance with 44 CFR,Section 65.3, as soon as practicable,but not later than six months after such data becomes available,a community shall notify FEMA of the changes by submitting technical data for a flood map revision. To obtain copies of FEMA's Flood Map Revision Application Packages, please refer to the FEMA website at htto://www.fem&gov/business/nfiv/foms.shtm. Please Note: Many NFIP participating communities have adopted floodplain management building requirements which are more restrictive than the minimum federal standards described in 44 CFR. Please contact the local community's floodplain manager for more information on local floodplain management building requirements. The Orange County floodplain manager can be reached by calling Penny Lew,Floodplain Manager,at(714)647-3990.

The following comments are meant as guidance for the Lead Agency and should be incorporated into the Final MND. South Coast AOMD Staffs Summary of Pmiect Descrintion 4 A The Lead Agency proposes to demolish 39,047 square feet of structures, construct 10 facilities totaling 43,500 square feet,and rehabilitate 11 structures on seven acres(Proposed Project).The Proposed Project is located at I0844 Ellis Avenue within the 112-acre wastewater treatment Plant No. 1. Construction of the Proposed Project is expected to last approximately eight years[. Responsible Agency, South Coast AOMD Permits.and Rules Operation of portable engines and portable equipment units of 50 horsepower or greater that emit particulate matter require a permit from South Coast AQMD or registration with the Portable Equipment Registration Program (PERP) through the California Air Resources Board (CARB)'. It is recommended that the Lead Agency consult with South Coast AQMD's Engineering and Permitting staff to determine if any equipment during construction and/or operation will require a South Coast AQMD permit or need to be registered under the PERP through CARBs,and if the Proposed Project would be subject to any South Coast AQMD rules in addition to South Coast AQMD Rule 201 —Permit to Construct and Rule 203 — Permit to Operate. If a permit from South Coast AQMD is required, South Coast AQMD should be identified as a Responsible Agency for the Proposed Project in the Final MND. The assumptions in the air 4-B quality analysis in the Final MNO will be used as the basis for permit conditions and limits.If there is any information in the permitting process suggesting that the Proposed Project would result in significant adverse air quality impacts not analyzed in the Final MND or substantially more severe air quality impacts than those analyzed in the Final MND, the Lead Agency should commit to re-evaluating the Proposed Project's air quality impacts through a CEQA process (CEQA Guidelines Section 15162). For more information on permits, please visit South Coast AQMD's webpage at: http://www.agmd.goy/home/permits. Questions on permits can be directed to South Coast AQMD's Engineering and Permitting staff at(909)396-3385.

OC Local Enforcement Avg" T 1. The IS/M9D stated that a hazardous material survey(HMS)was completed but the HMS lllll 6_B wasn't included in the document so it's not clew how the project plans to segregate,store and dispose of hazardous and non-hazardous waste. 2. The IS/MND mentions Rainbow Disposal as the hauler of residential and commercial waste of Fountain Valley and that it has a material recovery facility(MRF)but it's not clew if Orange County Sanitation District(OCSD)plans to send all waste to Rainbow and then to Frank R. Bowerman(FRB).Alec,[hero is no mention of recycling of material. If 6-C the waste is transported to Rainbow Disposal, some of the material could be recycled, giving the city recycling credits which construct,and demolition projects usually need to show compliance with recycling goals of the state. 3. The hazardous material survey was included in the IS/M ND. It's unclear what type of sampling will be occurring to ensure that hazardous waste m soil is not going to Rainbow 6-D or FRB landfill.Concrete has beta known to have asbestos and should be tested prior to disposal or recycling. Soil could be contaminated with various chemicals and metals. 300 N.Pbaar again.Stares Are,CA azrm w .oWublmoAs.w P.C.Sox 404a.Santa Ana.CA 1127M4016 714667.8800 1In1o�nCPJJ.oc9ov.mn Comment Letter 6 OC HCA/Environmental Health Please see Ore following changes in red to the respective sections. 1. 4.19 Utilities and Service Systems Solid Waste Management Company/Republic Services operates a MRF located at 17121 Nichols Street with a design capacity of approximately, 2-,NG 4 000 tons per day (tpd). Non-raryclable materials and solid waste are then transported to the appropriate landfill. 2. Orange Counn, Waste and Recycling(OCWR)owns and operates rhrce active landfills serving the Orange County region.These include the Frank R.Bowerman Landfill(11002 Bee Canyon Access Road,Wine); Olinda Alpha Landfill(1942 N.Valencia Avenue,Brea),and the Prima Deshecha Landfill(32250 La Pate Avenue, San Juan Capistrano). The Olinda Alpha Landfill and the Prima Deshecha Landfill are open to the public while the Frank Bowerman Landfill is for commemiel use only. All three landfills arc permitted as Class HI landfills.Class Ill landfills accept only non-bamindous municipal solid waste for disposal; no hazardous or liquid waste can be accepted. Table 17 6-E describes the maximum permitted capacity of the serving landfills. 3. The landfill closest to the project coca is the Frank R.Bowerman Landfill,a 725-acre,non- hazardous,municipal solid waste landfill located approximately 13 miles northeast of the project area. The Frank R. Bowerman Landfill is permitted to receive 11,500 tpd, receives a daily average of approximately 6,800 tpd(Orange County Waste&Recycling 2017;City of Fountain Valley 2017b), and is scheduled to close in the year 2053(Orange County Waste&Recycling 2017).The landfill is subject to regular inspection by state and local regulatory agencies such as the California Department of Resource Recycling and Recovery(CalRecycle), the California Regional Water Quality Control Board(RWQCB),and the South Coast Air Quality Management District(SCAQMD). Please note that the Local Enforcement Agency(LEA) inspects the landfills monthly and the Stare inspects them every 18 months. 4.

CA 92 708-4 73 6 '(714)593-4425.FAX:(914)593-4525 May 23,2019 Kevin Hadden Orange County Sanitation District, Engineering/Planning 10844 Ellis Avenue Fountain Valley,CA 92708 SUBJECT: Headworks Rehabilitation at Plant No. I(Project No.P1-105) Dear Mr. Hadden, Thank you for the opportunity to comment on the Initial Study/Mitigated Negative Declaration (IS/MND)for the Headworks Rehabilitation at Plant No. 1 (Project No. P1-305). Our understanding is that the proposed project would consist of a combination of construction activities that include the rehabilitation of existing facilities, construction of new facilities,and demolition of existing facilities,as well as operating and maintaining facilities once construction and rehabilitation is complete. Rehabilitation activities would be mechanical and/or electrical 8-A in nature.All new above-grade structures would range between 18 and 39 feet in height. Demolition of existing facilities would generally include removal of concrete, steel, mechanical equipment, piping, electrical wiring, raceways and ductbanks,as well other utilities which may be present. Following our review of the IS/MND for the Headworks Rehabilitation at Plant No. 1 project, we have the following comment/concern: 1. Section 4.1.d Aesthetics (Page 22) — With construction hours staring at 7:00 am Monday through Friday, often delivery trucks arrive earlier than 7:00 am at a construction site and are left idling. Per Fountain Valley Municipal Code 6.28.147 (Idling Motor Vehicles), "No person shall leave standing any motor vehicle, including refrigeration trailers, with engine idling or auxiliary motor running for in excess of ten minutes between the hours of ten p.m. and seven a.m. if the engine or motor noise disturbs the peace or quiet of any residential neighborhood or causes discomfort or annoyance to any reasonable person of normal 8 B sensitivity residing in the area.The driver,owner, registered owner and legal owner of the motor vehicle or refrigeration trailer shall each be guilty of the offense described herein." Therefore, staff requests that staging of all delivery trucks, or any other type of motor vehicle associated with this project, occur on site within the OCSD property. Once again,thank you for the opportunity to review the IS/MND for the Headworks Rehabilitation at Plant No. 1 project. Should you have any questions about our comments, please contact me at(714) 593-4431 or email at steven.aversCdfountainvallev.ore.

The revisions do not significantly alter the conclusions in the IS/MND. Letter 1 : State Clearinghouse, Office of Planning and Research Comment 1-A The comment acknowledges the State Clearinghouse distributed the IS/MND as required under CEQA to pertinent agencies. Response 1-A The comment is noted and saved in the project record.No response is required because there are no specific comments on the contents in the Draft IS/MND. Letter 2: Federal Emergency Management Agency (FEMA) Comment 2-A The comment requests that the current Flood Insurance Rate Maps(FIRMS)for the County of Orange are reviewed as they were revised in March of 2019. The comment then states which cities are participants of the National Flood Insurance Program(NFIP).The comment provides the source for where NFIP building requirements are located,and summarizes primary NFIP floodplain management building requirements.The comment states that various participating communities have adopted more restrictive building requirements and provided a local contact to reach out to if there are any questions.

This area is protected from the one-percent-annual-chance flood by levee,dike, or other structures subject to possible failure or overtopping during larger floods(FEMA 2017a;FEMA 2017b). The FEMA Flood Map Service Center online database was accessed June 2019 to ensure that appropriate changes of flood classification were made to the Draft IS/MND after the March 2019 revision date. The project area is still classified as Zone X according to the FEMA database.No changes to the Draft IS/MND are required.The comment is noted and saved in the project record. No further response is required because there are no specific comments on the contents in the Draft IS/MND. Letter 3: California Department of Transportation (CALTRANS) Comment 3-A The comment acknowledges that CALTRANS has received and reviewed the Draft IS/MND and summarizes the project description.Additionally,the comment states that CALTRANS is a responsibly agency on this project. Response 3-A The comment is noted.No response is required because there are no specific comments on the contents in the Draft IS/MND. Comment 3-13 The comment states that access to Plant No. 1 is primarily through the I-405 and that the document should include a discussion of potential impacts of the project on 1 405 ramps and mainline. Further,the comment states that a discussion on the potential need for a Traffic Management Plan is required. Response 3-13 The Draft IS/MND evaluates the proposed project's impacts to traffic on page 106.The analysis notes that no detours, lane closures or road closures would be necessary. Although construction worker commutes would utilize I-405,the Draft IS/MND concludes that the additional 41 peak hour trips would not significantly impact the freeway on or off ramps. A traffic control plan is only required where a project would compromise lanes of traffic. Since no lanes of traffic would be compromised during construction,a traffic control plan is not necessary.

Response 3-C Although 1-405 is located within 0.15 miles of the construction area,the project would not impede traffic or contribute substantial numbers of traffic during peak hours. As a result,the Draft IS/MND concludes on page 106 that impacts to I-405 would be less than significant.No encroachment permit or additional consultation with Caltrans is necessary. Comment 3-D The comment states that coordination with the Project Management unit is required and provides the local contact information. Response 3-D Although 1-405 is located within 0.15 miles of the construction area,the project would not impede traffic or contribute substantial numbers of traffic during peak hours. As a result,the Draft IS/M ND concludes on page 106 that impacts to I-405 would be leas than significant.No encroachment permit or additional consultation with Caltrans is necessary. Comment 3-E The comment states that in the event of any activity in a CALTRANS right of way,an encroachment permit will be required.The comment then provides a source that refers to the Encroachment Permits Manual and then an additional contact for potential questions regarding the comment letter. Response 3-E The comment is noted and saved in the project record. The project would be implemented within the Plant No. 1 boundaries;therefore,no Encroachment Permit will be required.

The comment recommends that the Lead Agency consult with SCAQMD's Engineering and Permitting staff to determine if any equipment during construction and/or operation will require a South Coast AQMD permit or need to be registered under the PERP and if the project would be subject to any rules in addition to Rule 201 and Rule 203. The comment then states that if a permit from SCAQMD is required,the SCAQMD should be identified as a Responsible Agency for the project in the Final MND.The comment then states that assumptions in the air quality analysis in the Final MND will be used as the basis for permit conditions and limits and provides the Engineering and Permitting staff contact number. Response 4-13 OCSD will ensure that any equipment used during construction and operation of the proposed facility comply with all applicable permitting and regulatory requirements. Comment 4-C The comment then requests that OCSD provide SCAQMD with written responses to all comments on the Final IS/MND before project certification. The comment provides a staff contact number for questions or concerns. Response 4-C The comment is noted and saved in the project record.No response is required because there are no specific comments on the contents in the Draft IS/MND. Letter 5: Gabrieleno Band of Mission Indians — Kizh Nation Comment 5-A The comment acknowledges that the Tribal Government has received the Draft IS/MND and requests to be consulted if ground disturbance would occur with the project. Response 5-A Section 4.18,Tribal Cultural Resources of the Draft IS/MND describes the AB 52 Consultation Process that occurred for the project. OCSD has and will continue to coordinate closely with Native American Tribes within the project area,if requested. In September of 2017,OCSD consulted with Mr.Andrew Sales of the Gabrielefio Band of Mission Indians—Kizh Nation to understand tribal sensitivity of Plant No. 1.

The comment then provides a contact for the OC CUPA Program Manager. Response 6-A The comment is noted and saved in the project record.OCSD will continue to update/revise project facilities on the CERS,if required.No further response is required because there are no specific comments on the contents in the Draft IS/MND. Comment 6-13 The comment notes that a hazardous material survey(HMS)was completed but was not included in the document so it is not clear how the project plans to segregate,store and disposed of hazardous and non-hazardous waste. Response 6-13 The Draft IS/MND describes the hazardous materials management activities at Plant No. 1 beginning on page 72.The OCSD Plant No. 1 facility is an existing wastewater treatment plant with well-established hazardous materials handling procedures.The Draft IS/MND notes that the proposed upgrades would not change the existing operational requirements including preparation of hazardous materials Business Plans and compliance with other hazardous materials regulations. Comment 6-C The comment states that it is not clear if OCSD plans to send all waste to Rainbow Disposal and then to Frank R.Bowerman landfill. Further,the comment states that there is no mention of recycling material and explains that if the waste is transported to Rainbow Disposal,some of the material could be recycled.Last,the comment states that recycling would provide the city recycling credits,and demolition projects usually need to show compliance with recycling goals of the state. Response 6-C The Draft IS/MND states on page 117 that construction waste would be disposed of at the Bowerman landfill. Recycling waste would be the responsibility of the contractor.
