EPA Delays Valley PM2.5 Deadline to 2030
Published Date: 6/11/2026
Proposed Rule
Summary
The EPA is proposing to give the San Joaquin Valley in California an extra five years—until the end of 2030—to meet air quality standards for tiny pollution particles called PM2.5. This extension helps the area keep working on cleaning the air without rushing, affecting local residents and businesses. You can share your thoughts on this plan until July 13, 2026, and no new costs are expected right now.
Analyzed Economic Effects
2 provisions identified: 0 benefits, 0 costs, 2 mixed.
Five-year attainment date extension
The EPA is proposing to extend the Serious area attainment date for the San Joaquin Valley for the 2012 annual PM2.5 standard from December 31, 2025 to December 31, 2030. The proposal says the area’s 2024 plan projects narrow attainment by 2030 and that measures implemented between the end of 2025 and 2030 would cut over 4.3 tons per day of NOX and 0.2 tons per day of direct PM2.5; the EPA will accept public comments on the proposal through July 13, 2026. The summary of the proposed rule also states that no new costs are expected right now from this action.
Most Stringent Measures due by 2030
Under the Clean Air Act rules cited in the proposal, the State must demonstrate and implement the plan’s "most stringent measures" (MSM) and must implement MSM as expeditiously as practicable and no later than January 1, 2030 (the beginning of the year containing the requested December 31, 2030 attainment date). MSM are defined in the rulemaking as permanent, enforceable control measures that achieve the most stringent emissions reductions and must be shown to be technologically and economically feasible.
