Attachment 1
Environmental Information for Petition for Change Involving Transfer City of Sacramento – Permit 11359
Description of Proposed Changes
Petitioner City of Sacramento (“Sacramento”) proposes to transfer by groundwater substitution (“Transfer”) up to 10,366 acre-feet (“AF”) of surface water normally diverted by Sacramento under Permit 11359 and 11360 at its diversion facilities and delivered to its wholesale and retail customers. The groundwater pumped to support this transfer will be pumped by Sacramento, Sacramento Suburban Water District (“SSWD”), and Sacramento County Water Agency (“SCWA”). SSWD will forego receiving up to 3,214 AF of its contractual surface water supplies, SCWA will forego receiving 2,800 AF of its contractual surface water supplies, and Sacramento will forego 3,990 AF of its surface water supplies for the Transfer. Sacramento will leave that foregone surface water supply in the Lower American River for transfer to the following entities: Metropolitan Water District of Southern California, Kern County Water Agency, Alameda County Water District, Napa County Flood Control & Water Conservation District, Kings County Water District, Palmdale Water District, Dudley Ridge Water District, Zone 7 Water Agency, Central Coast Water Authority, and Antelope Valley-East Kern Water Agency. Collectively, SCVWD and SWCs are the “Buyers”.
Sacramento, SSWD and SCWA are part of group of Sellers that use surface supplies from the American River and groundwater from the North American Groundwater Subbasin and South American Groundwater Subbasin to meet their demands. The Sellers are collectively seeking to temporarily add points of diversion, a point of rediversion, places of use, and purposes of use to their water rights to enable transfer of approximately 16,101 acre-feet of surface water to the Buyers through groundwater substitution. The estimated availability of transferrable surface water will equal an amount negotiated between the California Department of Water Resources and the Sellers but will not exceed 16,101 acre-feet. The groundwater pumpers will extract up to 16,101 acre-feet of groundwater in the region to meet local demands otherwise served by the transferred surface supplies. This extraction is in accordance with the Groundwater Sustainability Plans (GSP) of both Sacramento Groundwater Authority and Sacramento Central Groundwater Authority. A consistency determination with both SGA’s GSP and SCGA’s GSAp has been provided as required by the Water Transfer Whitepaper.
The water supplies that Sacramento proposes to transfer to the Buyers will be within the portion of the SWP service area that comprises the Buyers’ individual service areas. To make the “Transfer Water” available to the Buyers, SSWD, SCWA, and Sacramento will pump groundwater to serve their customers’ demands that otherwise would have been served with surface water diverted and treated by Sacramento for delivery to serve those demands. In addition, SSWD and SCWA will pump groundwater to serve a portion of Sacramento’s customers’ demands that otherwise would have been met with treated surface water diverted by Sacramento. The portion of groundwater supplied by SSWD to Sacramento will be delivered through the Enterprise intertie into the jointly owned Howe Avenue Transmission Main. The portion of groundwater supplied by SCWA to Sacramento will be delivered through the Franklin Intertie at 5119 Lake Pleasant Drive in Sacramento, California.
To accomplish this groundwater substitution transfer, Sacramento is requesting that the State Water Resources Control Board (“SWRCB”) approve the following temporary changes to the City’s Water Right Permit Nos. 11359 and 11360:
1. Authorize additional points of diversion for the Transfer Water at the SWP’s Harvey O. Banks Pumping Plant via Clifton Court Forebay and the Barker Slough Pumping Plant Intake, and a point of rediversion at San Luis Reservoir;
2. Authorize an additional place of use for the Transfer Water within the service areas of the Buyers, which are all contained within the existing authorized SWP service area; and
3. Authorize additional purposes of use for irrigation, municipal and industrial, and domestic where those purposes are not specified in the existing water rights.
The existing points of diversion and rediversion, place of use and purpose of use in the City’s Permits would continue to be valid and utilized.
Sacramento will forego diversion of the Transfer Water in the Lower American River and Sacramento River and allow each Buyer (as stipulated in a separate Conveyance Agreement between the Buyers, each Seller and DWR) to take control of the Transfer Water at Sacramento’s point of diversion furthest downstream on the American River. The Transfer Water will then flow down the Sacramento River and across the Delta to the proposed additional temporary points of diversion. DWR then will divert the Transfer Water at the Banks Pumping Plant and Barker Slough Pumping Plant Intake. After diversion, the Transfer Water will either be conveyed for use in the Buyers’ service areas or potentially rediverted and stored in San Luis Reservoir or other facilities for later use by the Buyers. Conveyance of the Transfer Water will be scheduled in cooperation with DWR such that it will use available surplus release, pumping and transmission capacity and will not disrupt normal SWP operations. The proposed Transfer would be carried out in compliance with all existing laws and regulatory constraints on diversions from the Delta.
Only existing facilities will be utilized to accomplish the Transfer. The Transfer does not involve construction or modification of any facilities. Because the proposed Transfer would be conducted to replace existing water demands that otherwise would be unsatisfied in 2022 because of cutbacks in the Buyers’ SWP contractual entitlements, land uses within Sacramento’s service area and affected portions of the SWP service areas will not change as a result of this Transfer. This Transfer is needed to provide supplemental water supplies to the Buyers, which have been affected by reduced 2022 water supply allocations due to the dry hydrology. Because its purpose is to make up for unavailable water supplies normally used by the Buyers, the proposed Transfer will not result in any land use changes.
CEQA is not required for this proposed transfer because temporary water transfers (one year or less) under Water Code sections 1725 through 1732 are statutorily exempt from CEQA. (Water Code, § 1729; CEQA Guidelines, § 15282(u).) Sacramento will file a notice of exemption for this transfer upon the SWRCB’s approval of the Petition.
The proposed transfer will be conducted in compliance with the guidelines issued in the Draft Technical Information for Preparing Water Transfer Proposals as published by the California Department of Water Resources (“DWR”) and the U.S. Bureau of Reclamation. Sacramento and the other American River sellers will enter into a conveyance agreement with DWR that will stipulate specific and applicable implementation measures for the transfer to assure the transfer complies with subdivision (d) of Water Code section 1810.
The amount of potential changes in streamflow, water quality, timing of diversion or use, return flows, and effects on legal users of water will be insignificant or non-existent and therefore will not cause adverse economic, physical, or environmental effects. The transfer of up to 16,101 AF from the lower American River is a small increment of the water that will be bypassed from direct diversion along the American River during the transfer period of July 1 through November
30. Cumulatively, the bypass of direct diversion of the water rights held by the City of Sacramento, CWD, and San Juan Water District would equate to no more than approximately 70 cfs daily of additional flow in the lower American River between July 1 and September 30 and no more than approximately 40 cfs in October and November. The Transfer water will be released over several months on the same pattern it would have been diverted and used by the Sellers. The Transfer water left in the Lower American River will comprise an increasingly small increment of water as it flows downstream when compared to the flows in the lower American River, Sacramento River and the Delta.
As explained below, the Transfer involves a small quantity of water compared to the volumes of water moving through these river systems. Table 1 presents the average daily Delta outflow, river flows, and SWP and CVP pumping rates as average flow rates during the period July through November, which includes the proposed transfer period. The data presented in Table 1 averages flows from 2015 through 2021. This information provides context for the approximate average flow of 70 cfs in July through September from the transfer and 40 cfs for October through November for SWRCB consideration as required by Water Code §1727(b)(1).
Table 1 – Representative Average Monthly Flow Conditions for Various Locations along the Proposed Transfer Pathway (all values in cfs) 1
Because of the minimal changes to existing conditions, the environment will not be adversely affected by the proposed Transfer. The only effects of the Transfer on the environment will be a very slight increase in river flows from the current points of diversion along the Lower American River to the proposed points of diversion and rediversion at the SWP Facilities. It should be noted that any increases in flows resulting from the Transfer will be well within historical average flows in the affected streams.
When the Transfer water is diverted by the SWP Facilities, DWR will divert all water in compliance with all existing state and federal regulations, including the salmon and smelt biological opinions, Decision 1641, and existing regulatory requirements. Given the negligible flow rate compared to existing and historic operations, the Transfer will not unreasonably affect fish, wildlife or other instream beneficial uses.
(For additional details, please see accompanying Petition) Coordination with Regional Water Quality Control Board
This Transfer will not require any construction and its operation will not generate waste or wastewater containing sewage or chemicals of any kind. As explained in Attachment No.1 to the

Petition, the amount of water that Sacramento proposes to transfer will only slightly increase anticipated 2022 baseline water flows in the Lower American and Sacramento Rivers and in the Delta and will be within the range of historical flows. This negligible increase in estimated 2022 flows resulting from the proposed transfer is not expected to cause erosion, turbidity, or sedimentation.

Subject: City of Sacramento Petition for Change Involving Water Transfer Under Permits 11359, and 11360.
Dear Mr. Ekdahl:
On behalf of the City of Sacramento (City), enclosed are the following documents supporting a request by the City for a Petition for Change Involving Water Transfer (Petition) under the City’s Permits 11359 and 11360 (Permits).
1. Petition for Change Involving Water Transfers Form for each of the two Permits with Attachment. (one original and one copy).
2. Environmental Information Form with Attachment for each Permit describing how the permits will work together for the cumulative transfer (one original and one copy).
3. Two checks for a combined amount of $9,173 based on a total quantity proposed to be made available for transfer, up to 10,366 acre feet.
a. $4,586.50 to support a proposed transfer of 5,183 acre-feet under permit 11359 b. $4,586.50 to support a proposed transfer of 5,183 acre-feet under permit 11360
4. Two checks in the amount of $850/each to cover the fee for the Department of Fish and Wildlife.
The City is petitioning to temporarily add a point of diversion, point of rediversion, place of use, and purposes of use to its Permits 11359 and 11360 as part of a multi-agency groundwater substitution transfer from the American River region. The City is one of three sellers that rely on the American River for their surface water supplies and seek to transfer up to 16,101 acre-feet of water to participating State Water Contractor (SWC) Agencies through groundwater substitution. Two of the three sellers are petitioning the State Water Board to temporarily add points of diversion, points of rediversion, places of use and purposes of use to their water rights to enable the temporary transfer.
This petition is largely similar to the approved groundwater substitution transfer under permit 11360 in 2020. The addition of Permit 11359 is to better align with annual diversion reports to SWRCB and to better align with the City’s anticipated plan to rely upon rediversion of previously stored water in the summer and fall of 2022 as expressly provided for under those permits. While the City normally diverts water under the four permits through a single coordinated operating agreement with USBR, we recognize review of a proposed groundwater substitution transfer this year may be best facilitated by focusing on only two of the four permits that have rights dedicated to the City of
Sacramento by SWRCB from the Upper American River Project (UARP) storage facilities operated by Sacramento Municipal Utilities District (SMUD) and upstream of Folsom Reservoir. The interactions of agreements between SMUD, United States Bureau of Reclamation (USBR) and the City, are described under SWRCB Decision 893 to provide the City reliable access to previously stored water.
The City acknowledges that further storage under these permits was curtailed in short periods 2021, however access to diversion of the previously stored water was expressly provided by SWRCB rulemaking in 2021 given the prior storage actions. The City has identified that adequate storage in the UARP already exists to support the City’s necessary diversions for this year. The use groundwater in lieu of surface water as proposed within this Petition will allow this released flow to continue downstream to other beneficial uses rather than being diverted through the City’s points of diversion.
We recognize the urgent nature of transfers – involving agreements with buyers, petitions, review and approvals processes, and ultimately delivery to the buyers. We appreciate your attention to these petitions and ask that you contact us immediately if you have questions or require additional information.
Sincerely,
Brett Ewart

Petition for Change Involving Transfer
2022 American River Region
Temporary Groundwater Substitution Transfer Program
City of Sacramento – Permit 11360
Introduction
Several American River water purveyors (“Sellers”) have joined together to transfer up to 16,101 acre-feet of surface water during July, August, September, October, and November 2022 to Santa Clara Valley Water District (“SCVWD”) and a consortium of State Water Contractors (“SWC”) through the Dry Year Transfer Program. The SWC’s participants include: Metropolitan Water District of Southern California, Kern County Water Agency, Alameda County Water District, Napa County Flood Control & Water Conservation District, Kings County Water District, Palmdale Water District, Dudley Ridge Water District, Zone 7 Water Agency, Central Coast Water Authority, and Antelope Valley-East Kern Water Agency. Collectively, SCVWD and SWCs are the “Buyers”.
Sellers will forego using the surface supplies that they would otherwise divert from the American River in 2022 to serve their water demands and instead pump groundwater to serve their demands. The surface water supplies that will be transferred by Sellers are diverted under three post-1914 appropriative rights – License 1387 and Permits 11359 and 11360 – and one pre-1914 appropriative water right Statement of Diversion and Use (“SODU”) S000656. Each post-1914 appropriative water right requires the filing of a separate Petition for Change Involving Water Transfers (“Petition”) under Water Code sections 1725 through 1732 in order to request a temporary change to the point of diversion and rediversion, place of use, and purpose of use from the State Water Resources Control Board (“State Water Board”). And the transfer under S000656 requires United States Bureau of Reclamation concurrence and an analysis under the California Environmental Quality Act.
The City of Sacramento (“Sacramento”), one of the Sellers, is seeking to transfer up to 10,366 acre-feet under its two water right permits – Permit 11359 and 11360. Under this Petition for Change Involving Transfer (“Petition”) Sacramento seeks to transfer up to 5,183 acre-feet under Permit 11360. The total transfer under this Petition would contribute to the American River Region’s total transfer volume of up to 16,101 acre- feet. This document describes the proposed temporary regional American River groundwater substitution transfer (“Transfer”), the agencies participating in the Transfer, and the subcomponents that are specific to Sacramento’s Transfer under this Petition.
Temporary Groundwater Substitution Transfer
While this petition is focused exclusively on the City of Sacramento and its partnerships with Sacramento Suburban Water District and Sacramento County Water Agency to make City surface water available, the overall 2022 American River Region Temporary
2 Groundwater Substitution Transfer Program will include seven agencies that use surface water diverted from the American River watershed and groundwater pumped from two groundwater subbasins on the north and south sides of the American River: the North American Groundwater Subbasin (Basin I.D. 5-021.64)1 and the South American Groundwater Subbasin (5-021.65)2 (see Appendix A for Basin Descriptions). This Transfer reflects the regional cooperation among the participating public agencies to conjunctively manage their water supplies and integrate system operations.
The following water purveyors are participating in this regional Transfer either by providing surface water for delivery to the Buyers and pumping groundwater in lieu of surface water use in their own service areas or pumping and delivering groundwater to Sellers to satisfy area demands in lieu of the transferred surface water:
• City of Sacramento – Seller and groundwater pumper
• Carmichael Water District – Seller and groundwater pumper • Sacramento Suburban Water District – groundwater pumper • Sacramento County Water Agency – groundwater pumper
• San Juan Water District – Seller
• Citrus Heights Water District – groundwater pumper
• Fair Oaks Water District – groundwater pumper
Collectively, the participants will provide up to 16,101 acre-feet of surface water to Buyers and meet local demands with pumped groundwater that otherwise would have been served with the transferred surface water. The amount of surface water received by the Buyers at the point of delivery on the American River is subject to the ongoing discussions with the California Department of Water Resources related to streamflow depletion calculations.
The American River water purveyors have a comprehensive conjunctive management approach that accurately accounts for all extraction and recharge in the groundwater basins.
This program is described in more detail later in this Petition.
The Sellers are entering into two separate agreements with the Buyers that set forth the terms for the temporary groundwater substitution transfer. The Agreement with SCVWD is titled “Water Transfer Agreement Between Carmichael Water District, San Juan Water District, City of Sacramento, and Santa Clara Valley Water District” and the Agreement with DWR DYTP is titled the “Purchase Agreement for Water Transfer Between Buyer and Seller.” The groundwater pumpers will provide the groundwater that will be used in lieu of the transferred surface water supplies through existing regional management activities.
The Buyers will take delivery of the Sellers’ surface water and the California Department of Water Resources (“DWR”) will convey each Seller’s surface water supply pursuant to a separate “Conveyance Agreement.” The Conveyance Agreement will also allow DWR
1 California Department of Water Resources, Bulletin 118, https://water.ca.gov/Programs/Groundwater- Management/Bulletin-118.
2 California Department of Water Resources, Bulletin 118, https://water.ca.gov/Programs/Groundwater- Management/Bulletin-118.
3 to deliver the separate SCVWD surface water supply to the South Bay Aqueduct for eventual delivery to SCVWD’s service area as well as deliver water to the SWC participants. The requested temporary changes to Permit 11360 include the following:
1. Proposed New Users: Santa Clara Valley Water District, Metropolitan Water District of Southern California, Kern County Water Agency, Alameda County Water District, Napa County Flood Control & Water Conservation District, Kings County Water District, Palmdale Water District, Dudley Ridge Water District, Zone 7 Water Agency, Central Coast Water Authority, and Antelope Valley-East Kern Water Agency..
2. Proposed Additional Points of Diversion/Rediversion: No change in the City’s present points of diversion and rediversion are proposed. There are two additional points of diversion/rediversion to add: (i) The SWP’s Harvey O. Banks Pumping Plant (“Banks”) will be added as a point of rediversion and (ii) the Barker Slough Pumping Plant Intake (“North Bay Intake”) to allow the Department of Water Resources (“DWR”) to wheel the water to Buyers’ service areas. Both of these proposed additional points of rediversion are described in more detail below. The proposed additional points of rediversion is identified on maps filed with the Division of Water Rights under Application 5630 (SWP).
a. The first point of diversion is described as: Banks Pumping Plant via Clifton Court Forebay: N 2,126,440 ft., E 6,256,425 ft., California Coordinate System Zone 3, NAD 83, being within the NW 1/4 of SE 1/4 of Projected Section 20, T1S, R4E, MDB&M. This point of diversion is identified on the maps noted above.
b. The second point of diversion is described as: North Bay Aqueduct Intake via Barker Slough: North 216,350 fee and East 2,064,750 feet, California Coordinate System Zone 2, NW1/4 of SE ¼ of Projected Section 20 T5N, R2E, MDB&M. This point of diversion is identified on the maps noted above.
3. Proposed Point of Rediversion: The San Luis Reservoir (“SLR”) will be added as a point of rediversion from water diverted at Banks to allow DWR to wheel and remanage delivery of some of the Transfer water to the Buyers. SLR is identified on maps filed with the Division of Water Rights under Application 5630 (SWP).
Specifically, the point of rediversion for San Luis Reservoir is described as: N 1,845,103 ft., E 6,393,569 ft., California Coordinate System Zone 3, NAD 83, being within the NW 1/4 of SE 1/4 of Projected Section 20, T1S, R4E, MDB&M.
This point of rediversion is identified on maps filed with the Division of Water Rights under Application 5630 (SWP).
4. Proposed Additional Places of Use: The transferred water will be used within the Buyers’ specific service areas contained within the State Water Project’s (“SWP”) service area. The service areas are shown on the SWP service area map, Map
4 1878-1, 2, and 3 on file with the Division of Water Rights under Application 5630.
5. Proposed Additional Purposes of Use: Domestic, Municipal and Industrial, and Irrigation (for any such purposes not included as a purpose of use on each unique petitioner’s water rights).
The proposed Transfer involves surface water rights and groundwater production with established beneficial use histories and system interties that allow regional groundwater deliveries where necessary to facilitate the regional transfer approach. Table 1 summarizes the total transferable surface water supplies for each surface water right that results from the sustainable production well information for the participating groundwater pumpers. Sacramento will transfer surface water and Sacramento, Sacramento Suburban Water District (“SSWD”), and Sacramento County Water Agency (“SCWA”) will pump groundwater in lieu of using Sacramento surface water supplies. Carmichael Water District (“CWD”) will deliver surface water supplies and use CWD groundwater in lieu of the surface water supplies. San Juan Water District (“SJWD”) will transfer surface water supplies and Citrus Heights Water District (“CHWD”) and Fair Oaks Water District (“FOWD”) will use groundwater in lieu of the transferred surface water supplies.
Table 1 – Seller Groundwater Substitution and Surface Water Transfer Quantities
The Transfer Water depicted in Table 1 shows the maximum amount of transferrable surface water that the Sellers may transfer with sustainable groundwater pumping from its existing conjunctive use management actions. Sacramento will transfer 10,366 acre- feet of surface water and Sacramento, SSWD, and SCWA will pump 10,366 of groundwater (the sum of 3,214 AF, 2,800 AF, and 3990 AF) to serve their customers that would otherwise have received Sacramento’s surface water. Half of the proposed 10,366 transfer by the City of Sacramento is included within this specific petition. The remaining half is included in a companion petition.

5 Sacramento Transfer Proposal Under Permit 11360
This Petition is unique to the City of Sacramento’s Permit 11360. The information presented below follows the transfer rules under California Water Code sections 1725 through 1732 and California Code of Regulations section 794 et seq.
City of Sacramento
Sacramento seeks State Water Board approval for the Transfer under its post-1914 appropriative water right Permit 11360:
1. Current Points of Diversion and Rediversion: Sacramento’s points of diversion and rediversion under Permit 11360 include all of the following (precise details of the points of diversion and rediversion are provided in Permit 11360 documents and Decision 893): As noted in the City’s Application 012321 for P11360, up to 314,000 acre-feet per year is permitted for storage and eventual rediversion each year.3 This UARP water is stored and released under control and management of SMUD in the UARP for their own purposes and then dedicated to the City for consumptive use downstream.4 The water eventually makes its way downstream to be reimpounded and released from Folsom and Lake Natoma as operated by USBR for the City of Sacramento.5

2. Current Place of Use: City of Sacramento and vicinity, including additional portions of Sacramento County, as described in Permit 11360 and shown on maps applicable to Permit 11360.
3. Current Purpose of Use: Municipal, Domestic, Industrial and Recreational beneficial uses
Sacramento will forgo diverting 5,183 acre-feet of previously stored surface water under Permit 11360 and make that water available to Buyers. This water, less any component of the supply that is subject to recharge requirements imposed by the California Department of Water Resources in the Conveyance Agreement, would be delivered to Buyers for rediversion at Banks and the North Bay Intake for use in Buyer’s service areas. Upon State Water Board approval of the petition, the transfer will be exempt from CEQA review under Water Code section 1729. The remaining half of the overall proposed transfer (another 5,183 acre-feet) by the City will be under a companion petition for transfer for Permit 11359.
Sacramento has notified the United States Bureau of Reclamation (“Reclamation”) of its intent to transfer Sacramento’s water supply in accordance with the 1957 water rights operating agreement between the parties that was adopted by the State Water Board as part of Decision 893, with that agreement contractually obligating Reclamation to operate its American River storage facilities so as to make available in the American River sufficient water that originated from the various tributaries and points of storage in the Upper American River Project (UARP) for Sacramento’s diversions up to the amounts specified in the operating agreement. Because Permit 11360 and other agreements as recognized by SWRCB under D893 authorizes the City to divert water previously stored in Folsom Reservoir and various upstream reservoirs in SMUD’s UARP, the City’s ability to divert the previously stored water is excluded from curtailment under the State Water Board’s current curtailment methodology.
Streamflow Depletion Factor
The Sellers acknowledge that prior groundwater substitutions transfers have required a one-time streamflow depletion factor (SDF) between 8% and 13% to mitigate for losses of surface water over extended periods due to the Transfer. The Sellers also acknowledge the SWRCB’s concern that the 13% statewide SDF may not be adequately protective due to successive dry years barring a program to actively accelerate recharge. However, the Sellers have participated in an actively managed regional conjunctive use program for the past two decades. The results of this program can be seen in a statistical analysis of groundwater level trends6 completed by the California Department of Water Resources (DWR). The area of increasing groundwater levels (green) in Figure 1 below coincides with the service area of this Transfer. The DWR analysis was based on an annual
6 https://storymaps.arcgis.com/stories/b3886b33b49c4fa8adf2ae8bdd8f16c3
7 measured increments. As such, some areas of the basin have recovered by about 20 feet during the 20 year period. Note that nearly no other area in the state can demonstrate this trend over this period. Because groundwater levels have been increasing over this period, depletions from the lower American River have also declined. This further supports continuing use of the 13% SDF for this Transfer.
Figure 1. DWR Long-Term Groundwater Level Trend Analysis
A more recent example of prior conjunctive use activities can be seen following a Transfer completed in 2018, which saw an increase in groundwater pumping. When wet conditions emerged in 2019, the City of Sacramento returned surface water to its Transfer partners that pumped groundwater in 2018, resulting in substantial in-lieu recharge. This in turn resulted in spring 2020 groundwater elevations being higher than spring 2018 groundwater elevations, despite 2020 being a dry year. This mitigated the stream depletions associated with the 2018 Transfer. The City made this commitment to return the water under contract agreements. Figure 2 shows these increased groundwater elevations in two of the Transfer monitoring wells. As a reminder, the collective groundwater levels illustrated below are all improved from the period of record dating back to 1998 depicted in the DWR analysis shown above.
8 Figure 2. Groundwater Elevations in Two Transfer Monitoring Wells
Prior to this proposed 2022 Transfer, the City will again execute recharge agreements with partner agencies for return of the Transfer water during wet conditions when surface water is abundant. As an additional benefit, the City will enhance the return water by increasing amounts, up to an additional 25% of the Transfer volume depending on SWRCB evaluation of this petition. These agreements are designed to mitigate for SDF losses and ensure long-term groundwater sustainability; however, the City proposes to maintain a 13% SDF for the 2022 Transfer out of an abundance of caution in addition to the recharge agreements. The City will supply fully executed agreements to SWRCB upon approval by respective Boards or Councils.
9 Groundwater Pumper Information
The Transfer will include groundwater pumping by six participating public agencies that conjunctively use groundwater supplies pumped from the portion of the North American Groundwater Subbasin and South American Groundwater Subbasin within Sacramento County on both sides of the American River. The groundwater pumping will total up to 16,101 acre-feet of water in the months of July, August, September, October, and November as presented in Table 2. This groundwater substitution amount equals the surface water supplies proposed in the Transfer.

The groundwater pumping and use details of all groundwater pumpers related to this Transfer are described below. Only wells which have been approved by DWR and Reclamation will be used for the proposed Transfer, following the guidelines issued in the Draft Technical Information for Preparing Water Transfer Proposals, dated December 2019 (“White Paper”).7
In accordance with Water Code Section 1745.10, the groundwater pumping necessary to facilitate the Transfer is within historical pumping baselines for each participating agency and within the safe yield as determined by the Sacramento Groundwater Authority (“SGA”) and Sacramento Central Groundwater Authority (“SCGA”) under their respective Groundwater Sustainability Plans (“GSPs”). Moreover, the Transfer has obtained consistency determinations from both Groundwater Sustainability Agencies
7 California Department of Water Resources and United States Bureau of Reclamation, Draft Technical Information for Preparing Water Transfer Proposals, Information for Parties Preparing Proposals for Water Transfers Requiring Department of Water Resources or Bureau of Reclamation Approval, December 2019 (White Paper).
11 denoting that the Transfer comports with both GSPs as required by the White Paper.8 In addition, the agencies participating in the Transfer are actively participating in conjunctive use efforts in the region. Letters indicating consistency with the GSPs are attached as Appendix B to this Petition attachment. As a result, the pumping required for the Transfer will not result in undesireable affects to either the North American Subbasin or South American Subbasin.
Groundwater Pumpers Related to Permits 11359 and 11360
Only three of the groundwater pumpers participating in the Transfer will be using groundwater in lieu of surface water supplies that would have been provided to them under Permit 11359 and Permit 11360. The three groundwater pumpers are the City of Sacramento, Sacramento Suburban Water District, and Sacramento County Water Agency. The details of their groundwater pumping activities are described below.
City of Sacramento
Sacramento will pump a maximum of 3,990 acre-feet of groundwater in lieu of using surface water under Sacramento’s surface water supply Permits 11359 and 11360 that would otherwise have been used to meet customer demands in 2022. Sacramento will use the wells Sacramento identified in Table 3 below to pump the substitution water.
Sacramento’s proposed groundwater pumping is within its historical groundwater pumping and use, and the wells it will pump from to facilitate the Transfer have passed all certification requirements.
Sacramento Suburban Water District
SSWD will pump a maximum of 3,214 acre-feet of groundwater to replace surface water that would have otherwise been used under Sacramento’s Permits 11359 and 11360 to meet customer demands in 2022. Depending on internal demands, either all of this additional groundwater pumping will be used within SSWD’s service area in lieu of the Permit supply water historically used in SSWD under the 2004 Wholesale Agreement between the City and SSWD or, if remainder is available after satisfying SSWD internal demands, it will be delivered by SSWD to Sacramento through a metered intertie located on Enterprise Road and operated as part of SSWD’s Enterprise Pumping Plant and Storage Reservoir (“the Enterprise Intertie”). This substitution groundwater will be used in lieu of the City’s Permit surface water supplies that are normally used in the water rights place of use. SSWD will use the wells SSWD identified in Table 3 to pump the substitution water. The Enterprise Intertie allows Sacramento and SSWD to share water resources. Use of the facility during previous groundwater substitution transfers demonstrated that SSWD can deliver over 30 cubic feet per second (“cfs”) from SSWD operated groundwater wells to Sacramento while still meeting SSWD’s own customer needs. SSWD’s proposed groundwater pumping is within its historical groundwater pumping and use, and the wells it will pump from to facilitate the Transfer have passed all certification requirements. SSWD has been actively operating an in-lieu groundwater banking system since 1998, which has helped to recover groundwater levels in the North American Groundwater Subbasin in the area of Sacramento County north of the

12 American River. SSWD files reports on its conjunctive use activities with the State Water Board and SGA
Sacramento County Water Agency
SCWA will pump and deliver a maximum of 2,800 acre-feet of groundwater to replace surface water used under Sacramento’s Permits 11359 and 11360 that would have otherwise been used by the City in 2022 to serve its customers. SCWA will use the wells SCWA identified in Table 3 to pump the substitution groundwater at approximately 500 acre-feet per month from July through September and 650 acre-feet per month in October and November. SCWA’s proposed groundwater pumping is within its historical groundwater pumping and use, and the wells it will pump from to facilitate the Transfer have passed all certification requirements. SCWA will deliver the pumped groundwater through the metered Franklin Intertie located at 5119 Lake Pleasant Drive in Sacramento.
SCWA has been actively operating an in-lieu groundwater banking system since the mid 2000’s which has helped to increase groundwater levels in the South American Groundwater Subbasin in the area of Sacramento County south of the American River.
SCWA files reports on its conjunctive use activities with the Sacramento Central Groundwater Authority.

14 Groundwater Monitoring, Reporting, and Mitigation Plan As a condition of participation in the proposed temporary transfer, the Sellers have developed a Groundwater Monitoring, Reporting, and Mitigation Plan (“Plan”) to ensure the proposed transfer does not result in any unreasonable and adverse impacts to the groundwater basin or third parties. This Plan allows the Regional Water Authority (“RWA”) to coordinate monitoring and mitigation between Sacramento Groundwater Authority (“SGA”) and Sacramento Central Groundwater Authority (“SCGA”). The Plan accesses an expansive groundwater monitoring well network in order to conduct groundwater pumping measurements, monitor groundwater levels, evaluate groundwater quality, assess land subsidence, and prepare appropriate documentation describing the data gathered. The Plan is attached to this Petition as Appendix C.
The key characteristics of the Plan are outlined below for ease of review. The Transfer proponets will:
• Monitor in real time, through active SCADA systems, instantaneous water level measurements to show groundwater levels on a weekly timestep. These monitoring actions are ongoing functions in the GSPs and will be calibrated against threshold water level elevations.
• Monitor groundwater pumping with calibrated instantaneous flow meters to show groundwater pumping on a weekly timestep.
• Continue to monitor water quality derived from each drinking water well that meets all Tittle 22 water quality requirements administered by the State Board’s Division of Drinking Water.
• Report groundwater measurement results to the California Department of Water Resources on a monthly basis as well as prepare a final report on the Transfer evaluating impacts, if any, resulting from the Transfer.
• Coordinate among designated points of contact for monitoring and reporting of Transfer-related data.
• Reduce future groundwater extractions, if necessary, to ensure full recharge of an impacts resulting from the Transfer. These actions will be addressed in the the final Transfer report.
15 Other Transfer Information
The following information describes the entire Transfer proposal between the Sellers and the Buyers, and is inclusive of Sacramento’s contribution of surface water to the Transfer water quantity. All of the information provided below applies similarly to each Change Petition considered as part of the 2022 American River Temporary Groundwater Substitution Transfer Program considered by the SWRCB.
The surface water that will be delivered under the Transfer would have been consumptively used but for the Transfer as required under the White Paper guidelines.
Specifically, each Seller has historically used its surface water supply to meet consumptive uses within the water asset place of use. In this instance, the Sellers will forego using the surface water and use groundwater in lieu of the surface water transferred. Thus, the only water transferred will be water that otherwise would have been consumptively used.
In addition, absent the Transfer, neither the Sellers nor groundwater pumpers would use the groundwater that will be pumped as part of this transaction as part of the participating agencies’ on-going conjunctive use efforts consistent with SGA’s and SCGA’s Groundwater Sustainability Plans. But for the Transfer, the Sellers and groundwater pumpers would have used the surface water supplies described in this document to meet their customers’ demands. As such, the groundwater that will be used in lieu of the transferred surface water will only be pumped because of the Transfer.
Analysis of Streamflow, Water Quality and Other Affects The amount of potential changes in streamflow, water quality, timing of diversion or use, return flows, and effects on legal users of water will be insignificant or non-existent and therefore will not cause adverse economic, physical, or environmental effects. The transfer of up to 16,101 AF from the lower American River is a small increment of the water that will be bypassed from direct diversion along the American River during the transfer period of July 1 through November 30. Cumulatively, the bypass of direct diversion or rediversion of the water rights held by the City of Sacramento, CWD and San Juan Water District would equate to no more than approximately 70 cfs daily of additional flow in the lower American River between July 1 and September 30 and no more than approximately 40 cfs in October and November.
Downstream of City of Sacramento’s Fairbairn Water Treatment Plant the Transfer will increase the flow in the lower reach of the lower American River and in the Sacramento River by up to 70 cfs. The Transfer water will be released over several months on the same pattern it would have been diverted and used by the Sellers. The Transfer water left in the Lower American River will comprise an increasingly small increment of water as it flows downstream when compared to the flows in the lower American River, Sacramento River and the Delta.
As explained below, the Transfer involves a small quantity of water compared to the volumes of water moving through these river systems. Table 4 presents the average daily Delta outflow, river flows, and SWP and CVP pumping rates as average flow rates during the period July through November, which includes the proposed transfer period.
16 The data presented in Table 4 averages flows from 2015 through 2021. This information provides context for the approximate average flow of 70 cfs in July through September from the transfer and 40 cfs for October through November for SWRCB consideration as required by Water Code §1727(b)(1).
Table 4 – Representative Average Monthly Flow Conditions for Various Locations along the Proposed Transfer Pathway (all values in cfs) 9
The 16,101 AF of water will not be transferred all at once, but will be left in the lower American River and conveyed across the Delta to Banks and the North Bay Intake at the rate of approximately 70 cfs (approx.140 acre-feet per day) over the three-month July through September 2021 period and approximately 40 cfs (80 acre-feet per day) in the October and November 2021 period. The transfer of up to an additional 16,101 AF during this period would increase flow volumes and flow rates by only a very small amount compared to the total in any of the water bodies listed. Thus, while the exact operations required to implement the proposed Transfer cannot be stated with precision at this time, the Transfer will not affect streamflow or water quality. And, given that the Transfer is consistent with the historic and documented diversion rates of the Sellers, the Transfer will not affect the timing of diversion or use. The use of groundwater in-lieu of the surface diversions will not change the patterns and use of water by Sellers’ customers.
Thus, to the extent they exist, any return flows to the American River would remain unchanged. This action is unrelated to any changed release or operating decisions made

17 by USBR. This Transfer is in no way being proposed as a form of reservoir reoperation of federal facilities.
Because of the minimal changes to existing conditions, other legal users of water will not be adversely affected by the proposed Transfer. The only effects of the Transfer on other legal users of water will be a slight increase in river flows from the current points of diversion along the Lower American River to the proposed points of diversion and rediversion at the SWP Facilities. It should be noted that any increases in flows resulting from the Transfer will be well within historical average flows in the affected streams.
When the Transfer water is diverted by the SWP Facilities, DWR will divert all water in compliance with all existing state and federal regulations, including the salmon and smelt biological opinions, Decision 1641, and existing regulatory requirements. Given the negligible flow rate compared to existing and historic operations, the Transfer will not unreasonably affect fish, wildlife or other instream beneficial uses. A compliation of the downstream diversions between the existing points of diversion and the proposed points of diversion may be found on DWR’s eWRIMS database at the following link:

AMERICAN
Basin Boundaries
Summary
The South American Subbasin is a portion of the Sacramento Valley Groundwater Basin located in the Northern Region of California. The northern boundary is the American River, beginning at its confluence with the Sacramento River, and extending northeasterly, upstream to the City of Folsom where the boundary becomes the geologic contact between sediments and fractured bedrock for a short distance further northeast.
The eastern boundary is the geologic contact between sedimentary rock and fractured bedrock. The southern boundary extends southwesterly along the Cosumnes River to the confluence with the Mokelumne River and continues southwesterly to Dead Horse Cut (canal). The western boundary includes a short segment for Dead Horse Cut, Snodgrass Slough, and the Delta Cross Channel and then follows the Sacramento River to its confluence with the American River. The basin boundary is made up of seven (7) segments which are detailed in the descriptions below.

RE: 2022 Water Transfer Notification
Dear Mr. Peifer,
The City of Sacramento (COS), Sacramento Suburban Water District (SSWD), Carmichael Water District (CWD), Citrus Heights Water District (CHWD), Fair Oaks Water District (FOWD) and San Juan Water District (SJWD) have identified an opportunity to participate in a regional groundwater substitution transfer (Transfer) over the period of July 1st, 2022 to November 30th, 2022. In preparing the transfer document, the regional partners are following the Department of Water Resources (DWR) draft 2019 guidebook. See link below:
https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/State-Water- Project/Management/Water-
Transfers/Files/Draft_WTWhitePaper_20191203.pdf?la=en&hash=F0ACE02168387A77EDDDB844545E7 F7A4642A05F
We draw your attention to page 30, which identifies a required consultation with the appropriate GSA.
Excerpt below:
Pursuant to DWR’s latest draft guidebook for preparing water transfer proposals, this letter is intended to serve as a request for concurrence that the proposed transfer is consistent with the recently adopted Groundwater Sustainability Plan (GSP) for the North American Subbasin (NASb).
Participation will be achieved in the following fashion:
1) COS will preferentially utilize up to 3,400 acre-feet (ACFT) of additional groundwater over recent wet/non-transfer year extractions in the Transfer window, and 2) SSWD will preferentially utilize (or deliver to COS) up to an additional 3,200 ACFT rather than receive surface water from COS, and
3) CWD will reduce surface water diversions and rely instead on its own groundwater resources by an estimated additional 1,200 ACFT and relying on the equivalent groundwater supply from its own sources, and
4) SJWD will forgo up to 4,302 ACFT of surface water diversions, which will be replaced by combined groundwater extractions by CHWD and FOWD.
The additional dry year extractions from the collective agencies will be approximately 12,000 ACFT over recent wet/non-transfer year baseline conditions as defined by DWR in the 2019 White Paper.
The proposed extractions from the collective agencies are within historic extractions that have been reduced in recent years by a combination of reduced customer demand and/or reliance on surface water. They, and the proposed transfer volumes, are also understood to be consistent with the Sacramento Groundwater Authority (SGA) Water Accounting Framework (WAF).
COS, CWD, and SJWD will return to normal surface water diversions when hydrologic conditions are appropriate to maintain a positive balance in the WAF.
The collective agencies also understand the recently submitted GSP contemplates the increased reliance on groundwater during drier hydrologic conditions as proposed herein and thus understand the proposed Transfer to be consistent with the GSP.
We also believe this program is consistent with the commitments under the Water Forum to shift toward groundwater reliance during drier conditions and then rely more on surface water when hydrologic conditions are more favorable (I.e., practice conjunctive use). On April 11, 2022, the Water Forum issued its monthly runoff report. The Lower American River projected March through November runoff of currently 729 TAF, which is a “Wedge Year” as defined by the Water Forum.
Please note that other parties in the South American Subbasin, including COS and Sacramento County Water Agency are both considering participation in the Transfer. The Transfer volumes included in this notification letter, unless otherwise noted, would occur exclusively in the North American Subbasin In closing, COS, SSWD, CWD, CHWD, FOWD, and SJWD wish to highlight a key component of the planned Transfer, all additional groundwater extracted as part of the 2022 Water Transfer, will be returned in the form of in-lieu recharge through greater reliance on surface water during appropriate hydrologic conditions.
Please do not hesitate to contact us if you have any questions.

Dear Ms. Lee, Mr. Ewart, Mr. Gray, Mr. Helliker, Mr. Straus and Mr. York,
This is in response to your 2022 Water Transfer Notification dated April 21, 2022. Your letter indicates that your agencies intend to extract up to an additional 12,000 acre-feet of groundwater from the North American Subbasin between July 1, 2022 and November 30, 2022 to participate in a proposed groundwater substitution transfer.
The California Department of Water Resources 2019 Water Transfer White Paper (draft) requires consultation with the appropriate Groundwater Sustainability Agency (GSA) to determine consistency with the applicable Groundwater Sustainability Plan (GSP). The Sacramento Groundwater Authority (SGA) serves as the GSA for all of the area from which the pumping will occur, as well as serving as the administering agency for the North American Subbasin GSP.
After review of the proposed groundwater extractions, SGA finds that the actions are consistent with the GSP. The volumes of groundwater extraction and the potential for transfers as a part of a conjunctive use program for the subbasin were fully considered in GSP development and found to be consistent with the long-term sustainability of the groundwater resource. We also find that the proposed operations are consistent with the SGA Water Accounting Framework adopted by SGA in 2010.
Please feel free to contact Rob Swartz of my staff at [email protected] or 916-607- 9208, if you need any additional information.
Sincerely
James Peifer

RE: 2022 Water Transfer Notification
Dear Mr. Woodling,
The City of Sacramento (COS), and the Sacramento County Water Agency (SCWA) have identified an opportunity to participate in a regional groundwater substitution transfer over the period of July 1st, 2022 to November 30th, 2022 subject to approval by the COS Council and SCWA Board of Directors. In preparing the transfer document, the regional partners are following DWR’s draft 2019 Water Transfer White Paper. See the link below:
https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/State-Water- Project/Management/Water-
Transfers/Files/Draft_WTWhitePaper_20191203.pdf?la=en&hash=F0ACE02168387A77EDDDB844545E7 F7A4642A05F
We draw your attention to page 30, which identifies a required consultation with the appropriate GSA.
Excerpt below:
Pursuant to DWR’s latest draft guidelines for preparing water transfer proposals, this letter is designed to serve as a request for consultation that the proposed transfer is consistent with the recently submitted Groundwater Sustainability Plan (GSP) for the South American Subbasin (SASb). Participation in the Transfer will be achieved in the following fashion:
Sacramento County Water Agency will deliver approximately 2800 acre-feet of groundwater to the City of Sacramento through the Franklin Intertie, thereby allowing the City to reduce surface water diversions from the Lower American River.
The City will preferentially increase municipal pumping by up to 1700 acre-feet, further reducing surface water diversion.
Consistency with GSP
In evaluating the increased groundwater pumping against the SASb GSP, SCWA and COS provide SCGA with the total planned extractions for the SASb:
Total municipal extractions for the SCWA are planned to be less than 27TAF, which includes the 2800AF to COS (Exhibit 1). SCWA also encourages the reviewer to consider significant investments in the surface water diversion, treatment and delivery infrastructure that has resulted in increased volumes of surface water imported into the basin in-lieu of groundwater since 2012. This overall planned extraction for 2022 is lower than projected dry year extractions in the SCWA 2020 Urban Water Management Plan Multi-year drought forecasts (Exhibit 2) and is also lower than projected dry year extractions in the GSP (Exhibits 3 &4).
City municipal groundwater extractions in the SASb has typically ranged from 1000-2500 acre-feet in any given year. This year the maximum extraction for municipal needs is expected to not exceed 3000 acre-feet, which includes the proposed Transfer volume of up to 1700 AFY. The GSP exhibit for COS (Exhibit 5) is inclusive of north and south projections but is provided here for consistency.
Exhibit 6 is an excerpt from the water demand and supply tables for each entity in the SASb area that were used to support the modeling analysis in the GSP. This table provides detailed assumptions for the COS water use for the SASb area. Exhibit 7 is an excerpt from the recently completed Groundwater Master Plan for COS. Please note that page 4-6 in the GSP indicated the incorporation of the Groundwater Master Plan into the modeling which supported the GSP. In all cases, the planned extractions for the City’s proposed Transfer are lower than anticipated within the GSP. This is inclusive of non-potable irrigation pumping dispersed throughout COS (north and south of the American River) for parks and schools which are disconnected from the COS municipal system.
In summary, the planned extractions by the SCWA and COS are within the range of pumping volumes considered in the SASb GSP for each entity for both the Current and Projected conditions, which is indicative of no impacts on the SASb groundwater sustainability conditions based on the GSP.
We also believe this program is consistent with the commitments under the Water Forum to shift toward groundwater reliance during drier conditions i.e. “Conjunctive Use” and then rely more on surface water when hydrologic conditions are more favorable. On April 11, 2022, the Water Forum issued its monthly runoff report. The Lower American River projected March through November runoff of currently 729 TAF, which is a “Wedge Year” as defined by the Water Forum.
Return of Water
In 2020 SCWA and the City partnered on a similar transfer when SCWA sent the City 1,741AF of groundwater. During that Transfer, the COS committed to returning the water to the Basin. Exhibit 1 illustrates that COS completed that return within a year.
COS is committing to a similar return of water this year to allow recharge to occur. If deemed necessary by the Water Board to mitigate streamflow depletion concerns SCWA and COS are open to returning an increased percentage of the water proposed to be sent to COS.
Please note that other parties in the North American Subbasin, including COS, Sacramento Suburban Water District, Citrus Heights Water District, Fair Oaks Water District, San Juan Water District, and Carmichael Water District are all considering participation in the Regional Transfer. The transfer volumes included in this notification letter would occur exclusively in the South American Subbasin.
In closing, we wish to highlight a key component of the planned water transfer; All additional groundwater extracted as part of the 2022 Water Transfer is within past operational regimes and/or included within the SASb GSP. Through conjunctive use operations during appropriate hydrologic conditions recharge will be prioritized.
Please do not hesitate to contact us if questions arise.

RE: 2022 Groundwater Substitution Water Transfer
Dear Mr. Ewart and Mr. Hutcheson:
On April 19, 2022, the Sacramento Central Groundwater Authority (SCGA) received a notification that the City of Sacramento and Sacramento County Water Agency were considering undertaking a groundwater substitution water transfer over the period July 1, 2022 to November 20, 2022. The transfer would include the pumping of 4500 acre-feet of additional groundwater from the South American Subbasin and the forbearance of a like amount of surface water that would be transferred to parties outside the subbasin.
The California Department of Water Resources 2019 Water Transfer White Paper (draft) requires consultation with the appropriate Groundwater Sustainability Agency (GSA) to determine consistency with the applicable Groundwater Sustainability Plan (GSP). The SCGA serves as the GSA for all of the area from which the pumping will occur, as well as serving as the administering agency for the South American Subbasin GSP.
After review of the proposed groundwater extractions, SCGA finds that the actions are consistent with the GSP. The volumes of groundwater extraction and the potential for transfers as a part of a conjunctive use program for the subbasin were fully considered in GSP development and found to be consistent with the long-term sustainability of the groundwater resource.
Please contact me at (916) 812-9118 or [email protected] if you have any questions regarding this finding of consistency.
Sincerely,
John Woodling
GSP Manager, South American Subbasin
DRAFT – SUBJECT TO ADDITIONAL REVIEW AND COMMENT BY DEPARTMENT OF WATER RESOURCES Monitoring and Mitigation Program
This is a regionally-coordinated groundwater substitution transfer from areas north and south of the American River in Sacramento County. The following entities are participating in the proposed transfer either by providing surface water for delivery to the Buyers and/or pumping and delivering groundwater in lieu of the foregone surface water to meet local demands that otherwise would have been served with the transferred surface water:
• Carmichael Water District (CWD) Seller and groundwater pumper • City of Sacramento (COS) Seller and groundwater pumper • Sacramento County Water Agency (SCWA) groundwater pumper • Sacramento Suburban Water District (SSWD) groundwater pumper • San Juan Water District (SJWD) Seller
• Citrus Heights Water District (CHWD) groundwater pumper • Fair Oaks Water District (FOWD) groundwater pumper
The proposed transfer is being coordinated by the Regional Water Authority (RWA), which is the designated Regional Water Management Group by the Department of Water Resources (DWR) under the Integrated Regional Water Management (IRWM) Program. RWA is coordinating this transfer because of its potential to incentivize expanded conjunctive use operations within its IRWM planning area as a means of ensuring future water resources sustainability. RWA is coordinating with the Sacramento Groundwater Authority (SGA) and Sacramento Groundwater Authority (SCGA), which act as the respective Groundwater Sustainability Agencies (GSAs) over the transfer area in the North American and South American subbasins. This coordination will ensure that the monitoring plan objectives for the transfer proposal and the groundwater sustainability objectives of the GSAs are met.
Monitoring Well Network
The locations of the transfer and monitoring wells for the participating agencies are shown in Figure 1. There are 68 transfer wells and 24 monitoring wells that will each be monitored for the transfer. Location and construction information for each well will be uploaded to the WTIMS system.
Groundwater Pumping Measurements
Each of the transfer wells in the transfer is equipped with a calibrated instantaneous and totalizing flow meter. Each respective seller will be responsible for taking flow meter readings prior to initiation of pumping and at least monthly and as close to the end of the month as practical for the duration of the transfer period.
DRAFT – SUBJECT TO ADDITIONAL REVIEW AND COMMENT BY DEPARTMENT OF WATER RESOURCES Groundwater Levels
Water levels at monitoring wells will be collected in compliance with the December 2019 Water Transfer White Paper (White Paper). Each well has a trigger elevation and an associated well within 2 miles that will be monitored for the transfer. If monitoring of groundwater levels indicates that triggers established in the Monitoring Plan for transfer or associated wells have been exceeded, Seller will reduce or suspend pumping until the levels recover to above triggers associated with a specific pumping well and associated monitoring well.
SSWD has identified one transfer well (Well 65) that cannot be accessed for water elevations during the transfer. Well 65 has Well 33A that will be monitored and is less than 0.5 miles away; the well has similar construction. If the associated well encounters a trigger level, pumping at Well 65 will be reduced or cease pumping until such time as the associated well is in compliance. Attachment 1 to this Monitoring Program document is a table of all pumping and monitoring wells, their coordinates, top and bottom screen depths, trigger depths to water, and associated monitoring wells.
Shallow Groundwater Levels
There are no concerns with deep rooted vegetation associated with potential groundwater- dependent ecosystems (GDEs) in the transfer area. To assess this, the DWR-provided coverage of Natural Communities Commonly Associated with Groundwater (NCCAG) dataset was evaluated. Each well was then assigned a 0.5-mile buffer to assess for nearby potential GDEs.
None of the wells evaluated fell within the criteria of supporting deep-rooted vegetation and having groundwater levels between 10 to 25 below ground surface.
Groundwater Quality
Each of the transfer wells is a municipal supply well that meets Title 22 water quality requirements as administered by the State Water Resources Control Board Division of Drinking Water. Each participating agency is prepared to submit a three-year summary of specific conductance and total dissolved solids upon request by DWR. Known contaminant plumes are shown in Figure 2. These are not anticipated to be affected by transfer pumping for the following reasons: 1) the proposed pumping is well within the bounds of past pumping practices by the participating agencies; and 2) detailed, site-specific contaminant capture modeling has been conducted at the Aerojet and McClellan contaminant plumes by the respective responsible parties – results indicate effective capture with planned municipal groundwater use.
DRAFT – SUBJECT TO ADDITIONAL REVIEW AND COMMENT BY DEPARTMENT OF WATER RESOURCES Land Subsidence
Land subsidence is not a concern in the groundwater substitution area. Agencies in the region participated with DWR in its 2017 GPS Survey of the Sacramento Valley Subsidence Network.
The report compared the elevations of the valley-wide network in 2017 to the benchmark elevations established in 2008. The results of the survey clearly demonstrate that subsidence is not an issue on the eastern side of the valley, particularly in the Sacramento municipal area.
Locations of the benchmarks and the elevation difference from 2008 to 2017 are shown in Figure 3.
In addition to the recent DWR work, SGA extensively analyzed available information with respect to subsidence during development of its 2014 Groundwater Management Plan (GMP) in the transfer area north of the American River. Subsidence is not considered a concern in the SGA area as only slightly more than 2.2 feet of total subsidence was estimated between 1947 and 1991 based on USGS measurements associated with about 90 feet of groundwater level decline (rate of 0.02 feet subsidence per foot of drawdown). There was no documented damage associated with this estimated subsidence. Additionally, the 1990s represented the lowest point of groundwater elevations in the area. Since that time, local agencies have committed to a conjunctive program through the historic Water Forum Agreement of 2000.
Over the past 20 years, water levels have increased in the basin relative to their historic lows.
RWA will collect water level measurements from the participating agencies and compare them to the trigger values at these wells. RWA will report these results to DWR on a regular basis. If monitoring of groundwater levels indicates that triggers established in the Monitoring Plan for transfer or associated wells have been exceeded, Seller will reduce or suspend pumping until the levels recover to above triggers associated with a specific pumping well and associated monitoring well. If any groundwater elevations exceed these thresholds, additional monitoring and mitigation measures will occur. For monitoring, nearby wells will be checked to see if there is a regional extent to the drawdown or if it is very localized to the well. If the drawdown is regionally extensive, additional monitoring will occur. DWR’s Sacramento-valley wide land subsidence monitoring network for potential land surface elevation monitoring (see Figure 3) is available. A measurement by a licensed land surveyor will be collected at the soonest practical time following identification of an exceedance in a threshold groundwater elevation at the benchmark nearest the monitoring well with the exceedance. An additional measurement will be taken one month later. Based on those results, RWA will consult with DWR on additional potential subsidence monitoring or mitigation measures, including possible reduction or cessation of pumping.
Coordination Plan
Each of the seller agencies has designated a point of contact (POC) that has been identified in their respective transfer proposals submitted through WTIMS. The POC will be responsible for DRAFT – SUBJECT TO ADDITIONAL REVIEW AND COMMENT BY DEPARTMENT OF WATER RESOURCES communication with the well operators and other decision makers, and for the monitoring and reporting of transfer-related data. The POCs are:

Evaluation and Reporting
Each of the participating agencies will collect data, evaluate the data, and provide summary tables of data to the Project Agencies through the WTIMS site during and after the transfer.
Additionally, the data will be provided to RWA for evaluation of potential impacts at the regional level. Water level data will be provided to RWA for the purposes of developing contour maps of pre-transfer, end of transfer, and recovered groundwater elevations in March following the transfer. Each of the participating agencies will coordinate with RWA in the preparation of a final report to identify any potential transfer related impacts.
Mitigation Process
If monitoring of groundwater levels indicates that triggers established in the Monitoring Program for the transfer or associated monitoring wells have been exceeded, the applicable Seller will reduce or suspend pumping until the levels recover to above triggers associated with a specific pumping well and associated monitoring well.
DRAFT – SUBJECT TO ADDITIONAL REVIEW AND COMMENT BY DEPARTMENT OF WATER RESOURCES Seller shall be the contact for third-parties claiming impacts to their groundwater pumping operations purportedly caused by Seller’s groundwater pumping pursuant to this Agreement.
Seller shall forward any third-party impact report and Seller’s proposed response to DWR within ten business days of Seller’s receipt of the report. This reporting will trigger the following actions:
1. Seller will meet, within two business days or as soon thereafter as the claimant is available, with the claimant to develop a full understanding of the basis for the reported impact.
2. Seller will contact DWR to report the claimed impact and the basis for the claim, within 5 business days.
3. Seller, the claimant, and, if necessary, a representative of DWR, will investigate the reported impact to determine the extent of the impact and the linkage between the operation of the wells participating in the transfer and the impact. This investigation will include analysis of groundwater level, groundwater quality, and groundwater production data and any other relevant information.
4. Based on the results of the investigation, Seller will determine whether mitigation measures are necessary. The mitigation measures may include cessation of pumping, reduction in hours of pumping, lowering pump bowls of affected well(s), providing a temporary alternative water supply, or other measures determined to be appropriate during the course of discussion and investigation. Seller shall develop the mitigation measures through consultation with the claimant. Seller shall provide a copy of the mitigation measures to DWR. Seller will strive to develop the agreed upon mitigation measures within 10 business days of meeting with claimant.
5. Seller shall implement the agreed upon mitigation measures and monitor the results of its implementation to confirm that its mitigation efforts have succeeded in substantially reducing or eliminating third-party impacts. Seller maintains adequate financial resources to cover impact assessment studies and other reasonably anticipated mitigation needs.
Because mitigation measures center on reduction or cessation of pumping, the financial requirements for implementing these measures is nominal.
If, after investigation, Seller agrees that an adverse impact occurred during its water transfer, Seller shall take measures to avoid the same impact during Seller’s future water transfers. Note that the same wells participated in the 2018 and 2020 transfers, with no documented impacts from transfer pumping.

Attachment 1
Environmental Information for Petition for Change Involving Transfer City of Sacramento – Permit 11360
Description of Proposed Changes
Petitioner City of Sacramento (“Sacramento”) proposes to transfer by groundwater substitution (“Transfer”) up to 10,366 acre-feet (“AF”) of surface water normally diverted by Sacramento under Permit 11359 and 11360 at its diversion facilities and delivered to its wholesale and retail customers. The groundwater pumped to support this transfer will be pumped by Sacramento, Sacramento Suburban Water District (“SSWD”), and Sacramento County Water Agency (“SCWA”). SSWD will forego receiving up to 3,214 AF of its contractual surface water supplies, SCWA will forego receiving 2,800 AF of its contractual surface water supplies, and Sacramento will forego 3,990 AF of its surface water supplies for the Transfer. Sacramento will leave that foregone surface water supply in the Lower American River for transfer to the following entities: Metropolitan Water District of Southern California, Kern County Water Agency, Alameda County Water District, Napa County Flood Control & Water Conservation District, Kings County Water District, Palmdale Water District, Dudley Ridge Water District, Zone 7 Water Agency, Central Coast Water Authority, and Antelope Valley-East Kern Water Agency. Collectively, SCVWD and SWCs are the “Buyers”.
Sacramento, SSWD and SCWA are part of group of Sellers that use surface supplies from the American River and groundwater from the North American Groundwater Subbasin and South American Groundwater Subbasin to meet their demands. The Sellers are collectively seeking to temporarily add points of diversion, a point of rediversion, places of use, and purposes of use to their water rights to enable transfer of approximately 16,101 acre-feet of surface water to the Buyers through groundwater substitution. The estimated availability of transferrable surface water will equal an amount negotiated between the California Department of Water Resources and the Sellers but will not exceed 16,101 acre-feet. The groundwater pumpers will extract up to 16,101 acre-feet of groundwater in the region to meet local demands otherwise served by the transferred surface supplies. This extraction is in accordance with the Groundwater Sustainability Plans (GSP) of both Sacramento Groundwater Authority and Sacramento Central Groundwater Authority. A consistency determination with both SGA’s GSP and SCGA’s GSP has been provided as required by the Water Transfer Whitepaper.
The water supplies that Sacramento proposes to transfer to the Buyers will be within the portion of the SWP service area that comprises the Buyers’ individual service areas. To make the “Transfer Water” available to the Buyers, SSWD, SCWA, and Sacramento will pump groundwater to serve their customers’ demands that otherwise would have been served with surface water diverted and treated by Sacramento for delivery to serve those demands. In addition, SSWD and SCWA will pump groundwater to serve a portion of Sacramento’s customers’ demands that otherwise would have been met with treated surface water diverted by Sacramento. The portion of groundwater supplied by SSWD to Sacramento will be delivered through the Enterprise intertie into the jointly owned Howe Avenue Transmission Main. The portion of groundwater supplied by SCWA to Sacramento will be delivered through the Franklin Intertie at 5119 Lake Pleasant Drive in Sacramento, California.
To accomplish this groundwater substitution transfer, Sacramento is requesting that the State Water Resources Control Board (“SWRCB”) approve the following temporary changes to the City’s Water Right Permit Nos. 11359 and 11360:
1. Authorize additional points of diversion for the Transfer Water at the SWP’s Harvey O. Banks Pumping Plant via Clifton Court Forebay and the Barker Slough Pumping Plant Intake, and a point of rediversion at San Luis Reservoir;
2. Authorize an additional place of use for the Transfer Water within the service areas of the Buyers, which are all contained within the existing authorized SWP service area; and
3. Authorize additional purposes of use for irrigation, municipal and industrial, and domestic where those purposes are not specified in the existing water rights.
The existing points of diversion and rediversion, place of use and purpose of use in the City’s Permits would continue to be valid and utilized.
Sacramento will forego diversion of the Transfer Water in the Lower American River and Sacramento River and allow each Buyer (as stipulated in a separate Conveyance Agreement between the Buyers, each Seller and DWR) to take control of the Transfer Water at Sacramento’s point of diversion furthest downstream on the American River. The Transfer Water will then flow down the Sacramento River and across the Delta to the proposed additional temporary points of diversion. DWR then will divert the Transfer Water at the Banks Pumping Plant and Barker Slough Pumping Plant Intake. After diversion, the Transfer Water will either be conveyed for use in the Buyers’ service areas or potentially rediverted and stored in San Luis Reservoir or other facilities for later use by the Buyers. Conveyance of the Transfer Water will be scheduled in cooperation with DWR such that it will use available surplus release, pumping and transmission capacity and will not disrupt normal SWP operations. The proposed Transfer would be carried out in compliance with all existing laws and regulatory constraints on diversions from the Delta.
Only existing facilities will be utilized to accomplish the Transfer. The Transfer does not involve construction or modification of any facilities. Because the proposed Transfer would be conducted to replace existing water demands that otherwise would be unsatisfied in 2022 because of cutbacks in the Buyers’ SWP contractual entitlements, land uses within Sacramento’s service area and affected portions of the SWP service areas will not change as a result of this Transfer. This Transfer is needed to provide supplemental water supplies to the Buyers, which have been affected by reduced 2022 water supply allocations due to the dry hydrology. Because its purpose is to make up for unavailable water supplies normally used by the Buyers, the proposed Transfer will not result in any land use changes.
CEQA is not required for this proposed transfer because temporary water transfers (one year or less) under Water Code sections 1725 through 1732 are statutorily exempt from CEQA. (Water Code, § 1729; CEQA Guidelines, § 15282(u).) Sacramento will file a notice of exemption for this transfer upon the SWRCB’s approval of the Petition.
The proposed transfer will be conducted in compliance with the guidelines issued in the Draft Technical Information for Preparing Water Transfer Proposals as published by the California Department of Water Resources (“DWR”) and the U.S. Bureau of Reclamation. Sacramento and the other American River sellers will enter into a conveyance agreement with DWR that will stipulate specific and applicable implementation measures for the transfer to assure the transfer complies with subdivision (d) of Water Code section 1810.
The amount of potential changes in streamflow, water quality, timing of diversion or use, return flows, and effects on legal users of water will be insignificant or non-existent and therefore will not cause adverse economic, physical, or environmental effects. The transfer of up to 16,101 AF from the lower American River is a small increment of the water that will be bypassed from direct diversion along the American River during the transfer period of July 1 through November
30. Cumulatively, the bypass of direct diversion of the water rights held by the City of Sacramento, CWD, and San Juan Water District would equate to no more than approximately 70 cfs daily of additional flow in the lower American River between July 1 and September 30 and no more than approximately 40 cfs in October and November. The Transfer water will be released over several months on the same pattern it would have been diverted and used by the Sellers. The Transfer water left in the Lower American River will comprise an increasingly small increment of water as it flows downstream when compared to the flows in the lower American River, Sacramento River and the Delta.
As explained below, the Transfer involves a small quantity of water compared to the volumes of water moving through these river systems. Table 1 presents the average daily Delta outflow, river flows, and SWP and CVP pumping rates as average flow rates during the period July through November, which includes the proposed transfer period. The data presented in Table 1 averages flows from 2015 through 2021. This information provides context for the approximate average flow of 70 cfs in July through September from the transfer and 40 cfs for October through November for SWRCB consideration as required by Water Code §1727(b)(1).
Table 1 – Representative Average Monthly Flow Conditions for Various Locations along the Proposed Transfer Pathway (all values in cfs) 1
Because of the minimal changes to existing conditions, the environment will not be adversely affected by the proposed Transfer. The only effects of the Transfer on the environment will be a very slight increase in river flows from the current points of diversion along the Lower American River to the proposed points of diversion and rediversion at the SWP Facilities. It should be noted that any increases in flows resulting from the Transfer will be well within historical average flows in the affected streams.
When the Transfer water is diverted by the SWP Facilities, DWR will divert all water in compliance with all existing state and federal regulations, including the salmon and smelt biological opinions, Decision 1641, and existing regulatory requirements. Given the negligible flow rate compared to existing and historic operations, the Transfer will not unreasonably affect fish, wildlife or other instream beneficial uses.
(For additional details, please see accompanying Petition) Coordination with Regional Water Quality Control Board
This Transfer will not require any construction and its operation will not generate waste or wastewater containing sewage or chemicals of any kind. As explained in Attachment No.1 to the

Petition, the amount of water that Sacramento proposes to transfer will only slightly increase anticipated 2022 baseline water flows in the Lower American and Sacramento Rivers and in the Delta and will be within the range of historical flows. This negligible increase in estimated 2022 flows resulting from the proposed transfer is not expected to cause erosion, turbidity, or sedimentation.
Photographs
The present and proposed points of diversion include existing facilities that are well known to and documented with the SWRCB’s Division of Water Rights (“Division”). In addition, the present and proposed places of use also are well known to and documented with the Division.
Providing photographs of the present and proposed points of diversion and places of use would be redundant and, therefore, none are included with this Environmental Information form.
Maps
Sacramento’s existing point of diversion on the American River at the Fairbairn Water Treatment Plant, and existing place of use are shown on the map filed with the Division for Permit 11359 and 11360. Sacramento’s existing place of use encompasses its retail service area, which is where the surface water proposed to be transferred would otherwise be used. The proposed temporary points of diversion for the SWP Banks Pumping Plant and Barker Slough Pumping Plant Intake, and the temporary point of rediversion at San Luis Reservoir are shown on maps filed with the Division for DWR’s Application 5630. The proposed additional place of use is a portion of the SWP service area, as shown on Map 1878 – 2 and – 3 on file with the Division under Application 5630.
Monitoring Program
This is a regionally-coordinated groundwater substitution transfer from areas north and south of the American River in Sacramento County. The following entities are participating in the proposed transfer either by providing surface water for delivery to the Buyers and/or pumping and delivering groundwater in lieu of the foregone surface water to meet local demands that otherwise would have been served with the transferred surface water:
• City of Sacramento (COS) Seller and groundwater pumper • Carmichael Water District (CWD) Seller and groundwater pumper • Fair Oaks Water District (FOWD) groundwater pumper
• Golden State Water Company (GSWC) Seller and groundwater pumper • Sacramento County Water Agency (SCWA) groundwater pumper • Sacramento Suburban Water District (SSWD) groundwater pumper
The proposed transfer is being coordinated by the Regional Water Authority (RWA), which is the designated Regional Water Management Group by the Department of Water Resources (DWR) under the Integrated Regional Water Management (IRWM) Program. RWA is coordinating this transfer as a pilot, because of its potential to incentivize expanded conjunctive use operations within its IRWM planning area as a means of ensuring future water resources sustainability. RWA is coordinating with the Sacramento Groundwater Authority (SGA) and the Sacramento Central Groundwater Authority (SCGA), which act as both the Groundwater Sustainability Agencies (GSAs) over the transfer area and the designated CASGEM monitoring entities. This coordination will ensure that the monitoring plan objectives for the transfer proposal and the groundwater management objectives of the GSAs are met.
Monitoring Well Network
The locations of the transfer and monitoring wells for the participating agencies are shown in Figure 1. There are 68 transfer wells and 25 monitoring wells that will each be monitored for the transfer. Location and construction information for each well has been uploaded to the WTIMS system.
Groundwater Pumping Measurements
Each of the transfer wells in the transfer is equipped with a calibrated instantaneous and totalizing flow meter. Each respective seller will be responsible for taking flow meter readings prior to initiation of pumping and at least monthly and as close to the end of the month as practical for the duration of the transfer period. Additionally, intertie meter readings between CWD and FOWD, COS and SSWD, and COS and SCWA will be taken on the same frequency.
Intertie locations are shown in Figure 1.
Groundwater Levels
Water levels at monitoring wells will be collected in full compliance with the December 2019 Water Transfer White Paper (White Paper). Each well has a trigger elevation and an associated well within 2 miles that will be monitored for the transfer. If monitoring of groundwater levels indicates that triggers established in the Monitoring Plan for transfer or associated wells have been exceeded, Seller will reduce or suspend pumping until the levels recover to above triggers associated with a specific pumping well and associated monitoring well.
SSWD has identified three transfer wells (13, 41, and 65) that cannot be accessed for water elevations during the transfer. Well 13 is in the middle of the SSWD wellfield, and it has five wells (MW-5, MW-10, 2A, 4B, and 40A) within one mile. Additionally, Well 41 has Well 28 and Well 65 has Well 33A that will each be monitored and are less than 0.5 miles away; each well has similar construction. If any of these associated wells encounters a trigger level, pumping at wells 13, 41, and 65 will be reduced or cease pumping until such time as all the associated wells are in compliance. Attachment 1 to this Monitoring Program document is a table of all pumping and monitoring wells, their coordinates, and top and bottom screen depths, trigger depths to water, and associated monitoring wells.
There are no concerns with deep rooted vegetation associated with potential groundwater- dependent ecosystems (GDEs) in the transfer area. To assess this, a map was created using the DWR-provided coverage of Natural Communities Commonly Associated with Groundwater (NCCAG) dataset. The map also includes the Spring 2019 depth to water contour map. Each well was then assigned a 0.5-mile buffer to assess for nearby potential GDEs. The maps are shown in shown in Figure 2 and Figure 3. Each of the 34 wells that intersected an NCCAG polygon is shown in the table below. Based on review of the Spring 2019, all but 7 of the wells had depths to water of greater than 40 feet. For the remaining 7 wells, recent depth to water readings from the wells were reviewed. These actual depths are shown in Table 1, with all wells except City of Sacramento Well 139 confirmed as greater than 40 feet.

Based on the relatively shallow depth to water at Well 139, additional depth to water data from Well 139 that was collected as part of the 2018 groundwater substitution transfer was reviewed. Table 2 below shows that prior to commencement of the transfer the depth to water was 33 feet. During the entire transfer period, the depth to water in the well was 30 feet or greater. Therefore, the groundwater table associated with the area around the well does not support a GDE.

Groundwater Quality
Each of the transfer wells is a municipal supply well that meets Title 22 water quality requirements as administered by the State Water Resources Control Board Division of Drinking Water. Each participating agency is prepared to submit a three-year summary of specific conductance and total dissolved solids upon request by DWR. Known contaminant plumes are shown in Figure 4. These are not anticipated to be affected by transfer pumping for the following reasons: 1) the proposed pumping is well within the bounds of past pumping practices by the participating agencies; and 2) detailed, site-specific contaminant capture modeling has been conducted at the Aerojet and McClellan contaminant plumes by the respective responsible parties – results indicate effective capture with planned municipal groundwater use.
Land Subsidence
Land subsidence is not a concern in the groundwater substitution area. Agencies in the region participated with DWR in its 2017 GPS Survey of the Sacramento Valley Subsidence Network.
The report compared the elevations of the valley-wide network in 2017 to the benchmark elevations established in 2008. The results of the survey clearly demonstrate that subsidence is not an issue on the eastern side of the valley, particularly in the Sacramento municipal area.
Locations of the benchmarks and the elevation difference from 2008 to 2017 are shown in Figure 5.
In addition to the recent DWR work, SGA extensively analyzed available information with respect to subsidence during development of its 2014 Groundwater Management Plan (GMP) in the transfer area north of the American River. Subsidence is not considered a concern in the SGA area as only slightly more than 2.2 feet of total subsidence was estimated between 1947 and 1991 based on USGS measurements associated with about 90 feet of groundwater level decline (rate of 0.02 feet subsidence per foot of drawdown). There was no documented damage associated with this estimated subsidence. Additionally, the 1990s represented the lowest point of groundwater elevations in the SGA area. Since that time, local agencies have committed to a conjunctive program through the historic Water Forum Agreement of 2000.
Over the past 20 years, water levels have increased in the basin relative to their historic lows.
Figure 6 shows a groundwater elevation contour map from Spring 1997 and Figure 7 shows a contour map for 2019. Note that groundwater elevations at the center of the cones of depression north and south of the American River have come up in excess of 20 feet.
In the transfer area south of the American River, subsidence is even lower than in the north area. SCGA described subsidence in its 2006 GMP as having a maximum rate of 0.007 feet subsidence per foot of drawdown. As in the north area, historic low groundwater levels in the south area were experienced in the early 1990s.
RWA will collect water level measurements from the participating agencies and compare them to the trigger values at these wells. RWA will report these results to DWR on a regular basis. If monitoring of groundwater levels indicates that triggers established in the Monitoring Plan for transfer or associated wells have been exceeded, Seller will reduce or suspend pumping until the levels recover to above triggers associated with a specific pumping well and associated monitoring well. If any groundwater elevations exceed these thresholds, additional monitoring and mitigation measures will occur. For monitoring, nearby wells will be checked to see if there is a regional extent to the drawdown or if it is very localized to the well. If the drawdown is regionally extensive, additional monitoring will occur. DWR’s Sacramento-valley wide land subsidence monitoring network for potential land surface elevation monitoring (see Figure 5) is available. A measurement by a licensed land surveyor will be collected at the soonest practical time following identification of an exceedance in a threshold groundwater elevation at the benchmark nearest the monitoring well with the exceedance. An additional measurement will be taken one month later. Based on those results, RWA will consult with DWR on additional potential subsidence monitoring or mitigation measures, including possible reduction or cessation of pumping.
Coordination Plan
Each of the seller agencies has designated a point of contact (POC) that has been identified in their respective transfer proposals submitted through WTIMS. The POC will be responsible for communication with the well operators and other decision makers, and for the monitoring and reporting of transfer-related data. The POCs are:

Evaluation and Reporting
Each of the participating agencies will collect data, evaluate the data, and provide summary tables of data to the Project Agencies through the WTIMS site during and after the transfer.
Additionally, the data will be provided to RWA for evaluation of potential impacts at the regional level. Water level data will be provided to RWA for the purposes of developing contour maps of pre-transfer, end of transfer, and recovered groundwater elevations in March following the transfer. Each of the participating agencies will coordinate with RWA in the preparation of a final report to identify any potential transfer related impacts.
