From CARB to Dairy Plus: The Environmental Issues Shaping Your Operation

Amanda sits down with Paul Sousa, WUD's Director of Environmental Services and Regulatory Affairs, to review the environmental presentation delivered at the recent Board of Directors meeting.

California Air Resources Board (CARB) & Dairy MethaneCARB is now actively developing dairy-specific methane regulations. Rule development begins in 2025, with regulations coming to the board by 2028 and implementation targeted around 2030. CARB is currently seeking stakeholder input on emissions measurement, mitigation strategies, and regulatory structure. The comment deadline has been extended to May 29th. WUD is preparing comments and encourages member input.

• SB 1383: Passed in 2016, SB 1383 requires dairies to reduce manure methane emissions 40% from a 2013 baseline by 2030. According to Paul, California dairies have already met that target.

• External Pressure: A recent Stanford Law School paper critiqued water quality regulation implementation for dairies statewide. Paul's take: largely recycled findings, low media traction. The message for producers isn't panic. It's making sure your operation stays in compliance.

Water Quality UpdatesNorth Coast: WUD submitted a draft groundwater work plan in September and is awaiting feedback from the regional board. A formal extension request is being filed. Central Valley: The CV Salts program is moving forward in the Modesto Groundwater Sub-basin, offering a 35-year extension on nitrate limits. A board vote is expected in June. State Water Board Remand Order: Still no update. Use this time to get your dairy in order, especially around whole-farm nitrogen balance.

Research Funding: Funds remaining from the former state pooling and marketing branches may be directed to the California Dairy Research Foundation via a grant process. An industry panel may be created to guide project selection. Priority areas include water quality, greenhouse gas emissions, and technologies that address both.

AB 411: Carcass Composting: CDPHE is developing BMPs required before dairies can begin on-farm carcass composting. Their initial framing raised concerns; WUD has pushed back and is making progress toward ensuring the BMPs reflect the law's actual intent.

Tricolored Blackbird Funding: It's nesting season. If Tricolored Blackbirds are nesting in your silage fields, you may need to delay harvest. NRCS is offering $945 per acre in compensation this year. Paul is doing outreach directly to affected producers.

Dairy Plus Program: Final RoundDairy Plus is expected to open in June with a 90-day application window, funding weeping walls, vermin filtration, and advanced manure separation technologies. This is the last round. Start now: identify your challenge, research the right technology, and talk to vendors before the window opens.
