The Environmental Protection Agency (EPA) has finalized a revision to Maricopa County's portion of Arizona's State Implementation Plan (SIP) under the Clean Air Act. This revision includes specific permit conditions for emissions offsets from replacing diesel-fueled waste trucks with cleaner vehicles, ensuring these reductions are federally enforceable. The EPA received no public comments on the proposal and has incorporated the permit conditions into the SIP, effective January 15, 2025. This action does not impose additional requirements beyond state law and does not require consideration of environmental justice impacts.
Simple Explanation
The EPA has made a new rule for Maricopa County in Arizona that says when old diesel garbage trucks are replaced with cleaner ones, the air quality improvements need to be officially recognized so they count. This rule starts on January 15, 2025, and doesn't change any other local laws.
