East Turlock Subbasin Groundwater Sustainability Agency Credit Split Policy

The East Turlock Subbasin Groundwater Sustainability Agency (ETSGSA) has adopted the Credit Split Policy to implement key components of the Sustainable Groundwater Management Act (SGMA) within its jurisdiction, targeting Projects 12 through 18 aimed at reducing groundwater extraction and enhancing aquifer recharge. This policy establishes a structured framework for allocating Consumed Surface Water Credits and Recharge Credits to Water Account Holders who use surface water for irrigation instead of groundwater or who operate facilities that directly recharge the aquifer. The amount of credit awarded is determined by the apportionment of project costs and benefits between ETSGSA and the Water Account Holder, reflecting the relative investment each party made in the surface water supply or recharge infrastructure. A recovery period is defined during which ETSGSA recoups its investment through reduced credit allocations, after which credit shares shift in favor of the Water Account Holder. Eligibility is contingent upon compliance with ETSGSA’s Rules and Regulations, including the submission of verified documentation such as meter data calibrated to AWWA standards, State Water Resources Control Board diversion reports, pump performance tests, electrical consumption records, and approved water balance calculations. Implementation of the policy occurs across the East Turlock Subbasin in Merced and Stanislaus Counties, California, with all credited activities required to take place within ETSGSA’s designated boundaries. Account holders must maintain a Water Account in good standing, pay all applicable fees, and formally agree to terms if using ETSGSA-funded infrastructure. While the policy does not constitute a procurement contract and lacks traditional federal acquisition elements such as FAR clauses, pricing, delivery schedules, or invoicing systems, it mandates rigorous reporting and verification procedures to ensure accurate credit allocation. Acceptance of credit claims is administratively handled by ETSGSA upon review of submitted documentation, with final approval resting solely with the agency. The policy is effective as of January 22, 2026, and all obligations are tied to ongoing compliance with state and local water laws. Primary coordination and contact for the program are managed by Mike Tietze, the Agency’s General Manager and Board Secretary, who serves as the main point of contact for compliance inquiries and reporting.
