Because of the connectivity of the projects, environmental clearance has been sought in a combined document project called the "Recycled Water Reservoirs R-41, R-42, and R-43" Project. The project consists of the construction of two - 2.0 million gallon (MG) steel recycled water storage reservoirs, R-42 and R-43, and one 0.5 MG steel recycled water storage reservoir, R-41. M/ AGENDA DATE: December 9, 2008 Page 2 SUBJECT: ENVIRONMENTAL ASSESSMENT/INITIAL STUDY AND ADOPTION OF A MITIGATED NEGATIVE DECLARATION FOR RECYCLED WATER RESERVOIRS R-41, R-42, AND R-43 PROJECT R-41 will be located on a site south of Sleepy Oak Road, west of Oak Canyon Drive, and southeast of State Route (SR) 142. R-42 will be located on a site south of High Vista Lane, northwest of Vellano Club Drive, and west of SR 142. R-43 will be located on a site south of Soquel Canyon Parkway and west of Pipeline Avenue. An EXIS and Mitigated Negative Declaration was prepared in compliance with the California Environmental Quality Act (CEQA) and the City's Guidelines for Implementing CEQA. The document was circulated for public comment from October 20 to November 21, 2008. Comments received were minor in nature and did not challenge the validity of the study or its findings. The City received one letter from the Soboba Band of Luiseno Indians indicating that the project falls within the bounds of its Tribal Traditional Use Areas. As such, the Soboba Band requests the presence of a Native American Monitor during archeological survey and/or at such time as any ground disturbance should occur. 2. The Inland Empire Utilities Agency submitted a letter in support of the project. 3. A letter was received from the State Clearinghouse with the Governor's Office of Planning and Research, which indicates that the document was circulated to various state agencies as required by CEQA. Only the State Water Resources Control Board provided a written response. A compilation of comment letters and corresponding responses is attached. The comments received were minor in nature and do not challenge the validity of the Initial Study and its findings. Staff recommends that the City Council approve the Environmental Assessment/Initial Study (EA/iS) and Mitigated Negative Declaration for the Recycled Water Reservoirs R- 41, R-42, and R-43 project. Staff further recommends that the City Council adopt the corresponding resolution associated with this EA/IS and MND.

R-43 will be located on a site south of Soquel Canyon Parkway and west of Pipeline Avenue. B. An Environmental Assessment (EA)/Initial Study (IS) for the proposed project was conducted on behalf of the City, was independently reviewed and analyzed by the City and, based upon the Environmental Assessment/initial Study in accordance with the State of California Environmental Quality Act, a California Public Resources Code Sections 21000, et seq., Guidelines, and Mitigation Monitoring Report have been prepared for the subject project. C. The City provided ample opportunities for the residents and other public agencies and organizations in the review and comment process by providing the required review time for the environmental documentation (Environmental Assessment/initial Study) from October 20, 2008 through November 21, 2008. D. The City Council held a duly agendized regular City Council meeting on December 9, 2008, at which time the City Council reviewed the environmental documentation (the Mitigated Negative Declaration and Initial Study), together with the written public comments received and the testimony thereon. SECTION 2. On the basis of its review and consideration of the environmental documentation and the project itself, and after due consideration of the oral and written testimony and other evidence received, the City Council hereby finds as follows: 1 of 3 A. The Environmental Assessmentlinitial Study (EA/IS) that was prepared for the project identified to include specific technical studies for Air Quality, Biological Resources, a Cultural Report, and a Paleontological Report. B.

As a state agency with jurisdiction by law to preserve, enhance, and restore the quality of California's water resources, the State Water Resources Control Board (State Water Board) is providing the following comments on the environmental document prepared for the Project. The Project would construct three recycled water reservoirs and minor connector pipeline segments in order to expand the use of recycled water in the Chino Hills area in San Bernardino County. The Project would expand the recycled water storage capacity by 2.5 million gallons, and reduce southern California's dependence on imported water from the Colorado River and the California Bay -Delta, The City is currently pursuing a water recycling grant (WR No. 3825-0a0) from the State Water Board. Please provide us with the following documents applicable to the proposed Project: . (1) Two copies of the draft and final IS/MND, (2) the resolution adopting the MND and making California Environmental Quality Act (CEQA) findings, (3) all comments received during the review period and the City's response to those comments, (4) the adopted Mitigation Monitoring and Reporting Program, and (5) the Notice of Determination filed with the Governor's Office of'. Planning and Research State Clearinghouse. Irraddition, we would appreciate notice of any hearings or meetings held regarding environmental review of any projects to be funded by the . State Water Board. We understand that the City is not pursuing funds from the Clean Water State Revolving Fund (CWSRF) Program for this Project. The City, may want to consider the CWSRF Program to provide funding for future construction. The State Water Board, Division of Financial Assistance, is currently responsible for administering CWSRF funds. The primary purpose for the CWSRF Program Is to implement the Clean Water Act and various state laws by providing financial assistance for wastewater treatment facilities necessary to prevent water pollution, recycle water, correct nonpoint source and storm drainage pollution problems, and provide for estuary enhancement, and thereby protect and promote health, safety and welfare of the inhabitants of the state. The CWSRF Program provides low -interest funding equal to one-half the most recent State General Obligation Bond Rates with a 20-year term. Applications are accepted and processed continuously. Please refer to the State Water Board's CWSRF website at www.waterboards.ca.aovlwater issues/oroorams/arants loans/srfrindex.shtml. California invfronrnentalProtectionAgency "led Paper Ms. Annie R. Dutrey . -2 - The CWSRF Program Is partially funded by the U.S. Environmental Protection Agency and requires additional "CEQA-Pius" environmental documentation and review. Three.enclosures are included that.further ekplain the environmehtal review process;and additional federal; requirements In the CWSRF Program. The-Stafe Wafer Board'ls regdired to'consult directly with agencies responsible for implementing federal environmental laws and regulations. Any environmental Issues'raised by federal agencies or their representatives will need to be resolved prior to State Water Board approval of a CWSRF funding commitment for the proposed Project: For further information on the CWSRF Program, please contact' Ms. Michelle L. Jones at (916) 341-6983. It is important to note that prior to a CWSRF funding commitment, projects are subject to provisions of the Federal Endangered Species Act, and must obtain Section 7 clearance from the.U.S. Fish and Wildlife. Service (USFWS), and/or National Marine Fisheries Service (NMFS) for any potential effects to special status species. Please be advised that the State Water Board will consult with USFWS, and/or NMFS regarding all federal special status species the Project has the potential to.impact if the Project is to be funded under the CWSRF Program. The City will need to identify whether the Project will involve any direct effects from construction activities or indirect effects, such as growth inducement, that may affect federally listed threatened, endangered, or candidate species that are known, or have a potential to occur on - site, in the surrounding areas, or in the service. area,.and to identify applicable. conservation measures to reduce. such effects.::.., In addition, CWSRF projects must comply with federal laws pertaining to cultural resources, specifically Section 106 of the National. Historic Preservation Act. The State. Wafer Board has' responsibility for ensuring compliance with Section 106 and the State Water Board's Cultural Resources Officer (CRO) must consult directly with the California State Historic Preservation Officer (SHPO). SHPO consultation is initiated when sufficient information is provided by the CWSRF applicant. Please contact the CRO, Ms.: Cookie Him, at (916) 341-6690, to find out more about the requirements, and to initiate the Section 106 process if the City decides to pursue CWSRr financing. Note that the City will need to identify the Area of Potential Effects (APE), including construction and staging areas and the depth of any excavation. The APE is three-dimensional and includes all areas that may be affected by. the Project. The APE includes the surface area and extends below ground to the depth of any project excavations. The records search request should be made for an area larger than the APE. The appropriate area varies for different projects but should be drawn large enough to provide information on what types of sites may exist in the vicinity. Other federal requirements pertinent to the Project under the CWSRF Program include the following: A. Compliance with the federal Clean Air Act: (a) Provide air quality studies that may have been done for the Project; and (b) If the Project is In a nonattainment area or attainment area subject to a maintenance plan; (I) provide a summary of the estimated emissions (In tons per year).that are. expected, from both the construction and operation of the Project for each federal criteria pollutant, in a nonattainment or maintenance area, and iridioate'if the nonattainment designation is moderate, serious, or severe (if applicable); California Environmental Protection Agency Co Recycled Payer Ms. Anne R.

Sincerely Lowell M. Jarvis Environmental Scientist California Enuirozznzental Protection Agency ed RegdedPaper Response to Comments Received Response to letter from the Soboba Band of Luisefio Indians The comment regarding the project area falling within the bounds of the Soboba "Tribal Traditional Use Areas" is noted and will be presented to the City Council prior to a final decision to proceed with the proposed project. The comment regarding a need for a Native American Monitor is noted. Please refer to the discussion under Section 5 of the Initial Study, Attachment 4 - Cultural Resources. The survey over all of the project area did not find any surface cultural resources within any of the project area of potential effect (APE). Over most of the reservoir acid pipeline sites, the cultural resources evaluation determined little or no potential for subsurface cultural resources. 2. Over a limited portion of the project APE, the cultural resources evaluation determined that a potential exists for subsurface resources to occur. For construction activities in these areas, mitigation measure V-2 requires monitoring by a qualified professional archaeologist. The City will afford the Soboba Tribe an opportunity to supply Native American monitors within these identified sensitive areas, and when construction is being planned for the identified sensitive areas, the Soboba Tribe will be notified and given an opportunity to participate in any consultation regarding the monitoring effort. Responses to the Letter from the State Water Resources Control Board, Division of Financial Assistance 1. The SWRCB understand(s) that the City is not pursuing funds from the Clean Water State Revolving Fund Program for this project. The City is not pursing funds from the CWSRF program at this time, but may avail itself of the opportunity at a future date. 2. If the City does pursue Proposition 84 funding for the project, then compliance with the Public Resources Code (PRC) §75102 is required ... the lead agency shall send the Project description and the Project site map to the California Native American tribes, which are on the contact list maintained by the Native American Heritage Commission (NAHC). The City, through its consultant, contacted the Native American heritage Commission via a facsimile letter dated February 11, 2008. The NAHC provided a list of Native American contacts via return facsimile on February 13, 2008. Please refer to Attachment 4 — Cultural Report of the Initial Study document for further details. The NAHC was included as a reviewing agency during the 30-day review period associated with State Clearing House comment period. Please refer to "Document Details Report, State Clearing House Date Base" for SCH No. 2008-101094. Define the length of pipeline that would be constructed to connect Reservoir R-43 to the recycled water system. Identify whether the pipeline would cross any ephemeral waterways. The City would need to construct approximately 1,361 linear ft (I-F) of 16-inch recycled water pipeline to connect R-43 to the recycled water system. The proposed routing of the pipeline would not cross any ephemeral waterways. 4. The substantiation is not explicit about whether or not connector pipelines would be constructed within existing access roads. All connector pipelines will be constructed within existing access roads. 5. Identify the current groundwater elevations at each reservoir construction site. The estimated groundwater table is at least 50-ft below ground level at the ridgeline sites for R-41 and R-42. The estimated groundwater table is at least 40-ft below ground level at the graded pad site R-43. 6. Quantify the maximum amount of precipitation that could be expected to occur, for example, in a 1 in 10 year rain event in the general area. An expected 1-hour point rainfall for a 10 year storm event is 0.93 inches. (Source: San Bernardino County Flood Control District Hydrology Manual.) 7, Describe the watershed impacts caused by changing the place of use of the reclaimed water. In a letter dated August 29, 2008, the State Water Resources Control Board, Division of Water Rights expressed concern to the City of Chino Hills that future growth in recycled water usage in the Santa Ana Watershed might the amount of water being discharged into the Santa Ana River. In an October 22, 2008 response to that letter, the Inland Empire Utilities Agency, who is the recycled water purveyor for this area, restated its ability to serve recycled water to the City and other member agencies without decreasing wastewater flow to the Santa Ana River in conformance with the 1969 Orange County Judgment. In an e-mailed response from the Division of Water Rights to the IEUA, the DWR indicated that the City's project meets the criteria with the proviso that the projected increase in wastewater is generated. (Please refer to attached documentation of the aforementioned correspondence.) 8. Once the project is constructed and placed into operation, the reclaimed water from this Project should not be allowed to flow into any of the drainage or creeks within the service area. The City of Chino Hills has both a Municipal Ordinance (Ord. 101) and administrative guidelines that govern the use of recycled water within its jurisdiction. In accordance with the City of Chino Hills' Municipal Code, § 13.32, the City will issue a permit for recycled water service which shall be a binding agreement between the City and the user. Such permit will be issued only after review of by the City, and approval by both the Santa Ana Regional Water Quality Control Board (SARWQCB) and the designated representative of the California Department of Health and Safety (DOHS). The permit will identify permitted/approved uses, estimated annual usage, maximum gallons per minute needed at point of connection, etc. 9. The City should consider measures that would reduce storm water and urban run off, such as Low Impact Development (LID). The Initial Study identifies mitigation item no. VIII-3 to contain post - construction runoff. In addition, the City will review and incorporate suggested LID practices where practicable. For example, the City could use open grade asphaltic concrete to pave the reservoir access road and still allow percolation of precipitation. Steve Nix m: Kathy Mrowka [KMROWKA@waterboards.ca.gov] nt: Thursday, October 23, 2008 7.44 AM ,o: Tom Love Cc: Steve Nix; Jason Gu Subject: Re: Chino Hills recycled water project - water rights response Thank you for the additional information regarding the Chino Hills Recycled Water Project. Based on the information, it appears that the recycled water project will rely upon increased treated wastewater associated with regional growth as its source of supply. The existing discharge from the wastewater treatment facility into the Santa Ana River will remain unchanged or will increase. A wastewater change petition is not required where there will be no decrease in instream flows. This project meets that criteria, provided that the recycled water facility comes on-line after the increased wastewater above current baseline is generated.

In response to your August 29, 2008, letter to the City of Chino Hills regarding the subject project and the wastewater flows. The recycled water supply for the Chino Hills project will be provided from two facilities, Regional Water Recycling Plant 5 (RP-5) and the Carbon Canyon Water Recycling Facility (CCWRF). These two facilities currently supply recycled flows to over 200 sites serving irrigation and industrial customers in the Cities of Chino and Chino Hills. The capacity of RP-5 has recently been re -rated by the Santa Ana Regional Water Quality Control Board increasing the permitted capacity from 15 mgd to 17.3 mgd. In addition, the CCWRF capacity is under evaluation for a permitted capacity increase from 10.4 mgd to 13 mgd. Since 2003, wastewater flows to these two facilities has increased from 17 mgd to 22 mgd (FY 2008) duo to growth in the service area. Although growth has slowed (3,800 units connected to the wastewater system in FY 2008 down from over 7,000 units in FY 2006) forecast growth, provided by the Cities, shows anticipated connections of approximately 4,000 units annually for the next 5 years with an increase in wastewater flows of over 5 mgd during that period. The City of Chino Hills proposed recycled water project will increase recycled water deliveries by 2,850 acre feet (2.5 mgd) over the next five years. Therefore, the proposed project will not result in any decrease of wastewater flow to the Santa Ana River from these supply facilities. I would appreciate your concurrence that the proposed project does comply with Water Code Section 1210 and Section 1211 since no reduction of wastewater flows will result from implementation of the project and I request a letter of determination that this will not require a petition for flung a wastewater change petition. If you have any questions or would like to discuss, please do not hesitate to call. Sincerely, ='INLAND EMPIRE pUT�� AGENCY i Thomas A.

The IEUA owns and operates five wastewater treatment plants throughout its service area. As reported In the IEUA•2000 Urban Water Management Plan, IEUA produces about 67,000 acre-feet (do of recycled water annually. In 20b0, recycled water use totaled 6,800 afa. The remaining supply of treated water, ever 60,000 at, was discharged to the Santa Ana River. ! Looking forward, the IEUA projects that available racycted•water supplies will exceed 100,000 afa.by 2020. In conformance with the 1969 Orange Bounty Judgment,17.000 afa of water will be discharged to the Santa Ana River. The July 28 submittal stated that more than, 75,000 of of water will be available for benefidlai.use within the IEUA service area in twenty years. Within the first five years of operating the three new.City recycled water.reservoirs, the total annual deliveries, at year five, is estimated at 2,850 afa. Thus, the'Cily asserts that the annual . acre-foot demand for recycled water within the City as a result of constructing the three resycied water'reservoirs will not impabt, decrease, or Impede the amount of water being discharged to the Santa Ana River. Only the owner of a wastewater facility can file a Wastewater Change Petition. (Wat. Code § 1211(a).) Consequently, IEUA would be the appropriate party to file any required petition. The Division of Water Rights (Division) is unable to accept a petition filed by the City.. The data that the City provided is for the year 2000. Therefore, Division staff cannot determine whether there has been any change in discharge to the river. Assuming.that the year 2000 : data Is still reflective of current discharges, iRU•A would not be required to file a petition as long as the existing 60,000 of discharge to the Santa. Ana River Is not reduced. if, however, there will be a reduction in discharge, a petition is required and must be approved prior to initlating• the change.
