Published Date: 6/11/2026
Proposed Rule
Summary
The EPA is proposing to give the South Coast area in California more time—until the end of 2030—to meet air quality standards for tiny pollution particles called PM2.5. This extension affects residents and businesses in Los Angeles and nearby areas, allowing extra years to clean the air without penalties. The EPA is asking for public comments by July 13, 2026, before making the final decision.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
South Coast PM2.5 Attainment Extended to 2030
The EPA is proposing to extend the South Coast (Los Angeles‑South Coast Air Basin) Serious area attainment date for the 2012 annual PM2.5 standard from December 31, 2025 to December 31, 2030. This change affects residents and businesses in Los Angeles and nearby areas (the South Coast area, home to about 17 million people) by giving five extra years to meet the PM2.5 standard and allowing extra time to clean the air without penalties.
Sanctions Clocks Terminated After Completeness Findings
The EPA issued completeness findings for elements of the 2024 South Coast PM2.5 Plan on December 17, 2024 and June 9, 2025, which the EPA says corrected prior submission deficiencies and terminated the sanctions clocks that had been started by EPA findings on May 26, 2023 and January 30, 2024. The earlier findings had started schedules for emissions offset sanctions (to apply 18 months after the findings) and highway funding sanctions (to apply 6 months after that), but those sanction clocks were terminated after the completeness determinations.
