Turlock Subbasin Groundwater Sustainability Plan (GSP) Program Environmental Impact Report (PEIR)The East Turlock Subbasin Groundwater Sustainability Agency is implementing a series of projects across Merced and Stanislaus counties, California, to reduce groundwater demand and enhance recharge systems. These efforts include the Santa Fe Ranch Floodwater Capture and Recharge Basin Project, the Sperry Farms Land Fallowing and Orchard Swale Rewilding Project, and the Braden Farms Orchard Swale Rewilding and Stormwater Retention Project. The scope of work involves both structural projects, such as the construction of berms and water retention basins, and management actions like land fallowing and the removal of almond orchards to incentivize conservation. Key activities include equipment mobilization, excavation, drainage modification, and the rewilding of orchard swales with native vegetation to improve aquatic habitats. All projects are governed by the Turlock Subbasin Groundwater Sustainability Plan and comply with the California Environmental Quality Act under Guidelines Section 15168, as they fall within the scope of the Program Environmental Impact Report. Implementation is generally scheduled to begin in the fall of 2025, with specific construction windows required after September 15 and before February 1 to avoid nesting bird seasons. Specialized requirements include the use of a qualified archaeologist for cultural resource protection and adherence to the NPDES Construction General Permit through a Stormwater Pollution Prevention Plan. Performance is measured by the successful reduction of groundwater demand and the recovery of groundwater levels through strategic land repurposing.

Proposed Amended Rule 461 Gasoline Storage and DispensingProposed Amended Rule 461, issued by the South Coast Air Quality Management District in California, aims to control volatile organic compound and toxic air contaminant emissions from gasoline dispensing facilities. The rule provides an alternative compliance path for non-retail operators to dispense fuel into vehicles equipped with Onboard Refueling Vapor Recovery systems without needing Phase II Enhanced Vapor Recovery systems, provided the vehicles are owned or controlled by the operator. The primary objective of the amendment is to streamline recordkeeping for operators with exclusively ORVR-equipped fleets by allowing the documentation of total daily fuel dispensing quantities in aggregate rather than on a per-vehicle basis. While the changes are not expected to result in further emission reductions, they are designed to reduce administrative burdens and provide greater flexibility and clarity for stakeholders. The update also includes editorial corrections and the removal of outdated provisions superseded by state reporting requirements.

Proposed Amended Rule 1157 PM10 Emission Reductions from Aggregate and Related OperationsProposed Amended Rule 1157, issued by the South Coast Air Quality Management District in California, aims to reduce PM10 emissions from aggregate and related operations. The rule expands its scope to include construction and demolition debris transfer stations and introduces stricter requirements for the frequency of dust suppressant applications and chemical stabilizers. It also establishes a new compliance pathway for periodic inspections of open storage piles, enhances recordkeeping mandates, standardizes facility signage, and increases penalties for recurring violations while removing obsolete regulations. To comply with these updates, applicable facilities may need to install new signage, rumble grates, and gravel pads. These measures are designed to address community concerns and improve overall air quality and public health. The forecast for this initiative was posted on September 4, 2026, with Farzaneh Khalaj and Ashley Dang serving as the primary points of contact.
