Placer County Air Rules Get EPA's Proposed Overhaul Nod

Published Date: 4/2/2025

Proposed Rule

Summary

The EPA wants to approve updated air pollution rules for Placer County, California, making it easier to control big pollution sources. This change fixes past problems and helps keep the air cleaner without penalties for now. Local businesses and builders should watch for final decisions soon, but no new fees or delays are expected yet.

EPA Proposes Approval of Local NSR Rule

The EPA is proposing to approve a revision to the Placer County (California) portion of the State Implementation Plan that updates the Clean Air Act nonattainment new source review (NSR) permitting program. The revision concerns how construction and modifications of major stationary sources of air pollution in nonattainment areas are regulated and is intended to address deficiencies previously identified by the EPA.

Deferral of CAA Sanctions for Placer County

The EPA is making an interim final determination elsewhere in the Federal Register that will defer the imposition of Clean Air Act (CAA) sanctions tied to the Agency's prior limited disapproval of the District rule. That deferral pauses the sanctions linked to the earlier limited disapproval while the Agency processes this proposed approval.
