Proposed rule.
Summary
The Environmental Protection Agency (EPA) is proposing to approve California’s plan for the Coachella Valley, an area that has not met the federal ozone health standard. The plan shows how the region will make “reasonable further progress” toward cleaner air by documenting current emissions, setting future limits for pollutants from sources such as factories and vehicles, and allocating “motor‑vehicle emissions budgets” that local planners must stay within. The goal is to bring ozone levels down to the standards set in 2008 for an eight‑hour average, protecting public health and the environment. The rule is issued by the EPA and applies to the Riverside County portion of the Coachella Valley, affecting state and local air‑quality agencies, businesses that emit ozone precursors, and the general public who live or work there. By accepting California’s state‑implementation plan (SIP) revision, the EPA would formally recognize the state’s strategy as meeting the Clean Air Act’s “extreme” non‑attainment requirements for that area. The proposal was published on October 29, 2026, and comments must be submitted by November 30, 2026. After the comment period closes, the EPA will review the feedback, make any necessary adjustments, and then issue a final rule. If finalized, the approved plan and its emissions budgets become enforceable, guiding future permitting and planning decisions in the Coachella Valley.
