Dear Mr. Hadden:
This is in response to your request for comments regarding the Notice of Intent Public Notice—
Orange County Sanitation District Public Notice,(NOI to Adopt Initial Study/Mitigated
Negative Declaration—Project Title: Headworks Rehabilitation at Plant No. 1 (Project No I-
105).
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.

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.
If you have any questions or concems,please do not hesitate to call Mark Delorey of the
Mitigation staff at(510)627-7015.

Mitigated Negative Declaration(MND)for the Proposed
Headworks Rehabilitation at Plant No. 1 (Project No.P1-105)
South Coast Air Quality Management District (South Coast AQMD) staff appreciates the opportunity to
comment on the above-mentioned document. 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.
Conclusion
Pursuant to CEQA Guidelines Section 15074,prior to approving the Proposed Project, the Lead Agency
shall consider the MND for adoption together with any comments received during the public review 4-C
process. Please provide South Coast AQMD with written responses to all comments contained herein

prior to the adoption of the Final MND. When responding to issues raised in the comments, response
should provide sufficient details giving reasons why specific comments and suggestions are not accepted.
There should be good faith, reasoned analysis in response. Conclusory statements unsupported by factual
information do not facilitate the purpose and goal of CEQA on public disclosure and are not meaningful,
informative, or useful to decision makers and the public who are interested in the Proposed Project. 4-C
South Coast AQMD staff is available to work with the Lead Agency to address any air quality questions
that may arise from this comment letter. Please contact me at Istmauaamd.eov should you have any
questions.

Dear W.Kevin Hadden:
Thank you for the opportunity to comment on the Initial Study and Mitigated Negative Declaration for the
Headwmks Rehabilitation at Plant No. 1 Project.The County of Orange offers the following comments
for your consideration.
OC Certified Dallied Program Agency MC CUPA)
1. The applicant ensures that new chemical storage tanks/chemicals ova 55 gallons are 6 A
updated/disclosed via California Environmental Reporting System(CERS)on their sites
CERS H)s.For assistance,please contact the OC CUPA Program Manager at 714-433-
6010 or the Fountain Valley Fire Department.
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.

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. The ISIMND should address the recycling component of solid waste disposal.Construction debris
such ea concrete can be recycled/crushed for reuse instead of being landfilled.In addition,most
construction projects are under mandatory recycling goals.Plan include a discussion specific to
recycling in Section 4.19 Utilities and Service Systems,I)Be served by a landfill with sufficient
permitted capacity to accommodate the pmjccVs solid waste disposal needs.

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

Response 2-A
Page 78 of the Draft IS/MND states the following:
The Federal Emergency Management Agency(FEMA)flood insurance maps show that
Plant No. 1 is located in an area designated as Zone X,Area with Reduced Risk Due to
Levee. 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.

Comment 4-B
The comment states that operation of portable engines/equipment units of 50 horsepower or
greater that emit particulate matter require a permit from SCAQMD or registration with the
Portable Equipment Registration Program(PERP)through the California Air Resources Board
(CARS). 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

Mitigation Monitoring and Reporting Program
CEQA Requirements
CEQA Guidelines Section 15097 requires a public agency to adopt a program for monitoring or
reporting on the changes it has required in the project or conditions of approval to substantially
lessen significant environmental effects.This Mitigation,Monitoring and Reporting Program
(MMRP)summarizes the mitigation commitments identified in the OCSD Headworks
Rehabilitation at Plant No. 1 (Project No.P1-105)(State Clearinghouse No.2019049152).
Mitigation measures are presented in the same order as they occur in the Public Review Draft
IS/MND.
The columns in the MMRP table provide the following information:
• Mitigation Measure(s): The actions)that will be taken to reduce the impact to a less-than-
significant level.
• Implementation,Monitoring,and Reporting Action: The appropriate steps to implement
and document compliance with the mitigation measures.
• Responsibility: The agency or private entity responsible for ensuring implementation of the
mitigation measure. However,until the mitigation measures are completed,OCSD,as the
CEQA Lead Agency,remains responsible for ensuring that implementation of the mitigation
measures occur in accordance with the MMRP(CEQA Guidelines, Section 15097(a)).
• Monitoring Schedule: The general schedule for conducting each task,either prior to
construction,during construction and/or after construction.
