Environmental Protection Agency November 19, 2020 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving the State Implementation Plan (SIP) revisions submitted by Idaho on June 5, 2019 and May 27, 2020. The submitted revisions update the incorporation by reference of specific Federal requirements and clarify source permitting requirements. The EPA finds that the changes are consistent with Clean Air Act requirements.

The Environmental Protection Agency (EPA) is finalizing revisions to the Calaveras County Air Pollution Control District (CCAPCD) and the Mariposa County Air Pollution Control District (MCAPCD) portions of the California State Implementation Plan (SIP). In this action, we are approving two rules, one submitted by the CCAPCD and the other by the MCAPCD, governing the issuance of permits for stationary sources, focusing on the preconstruction review and permitting of major sources and major modifications under part D of title I of the Clean Air Act (CAA or ``the Act'').

This rule finalizes amendments to the General Provisions that apply to National Emission Standards for Hazardous Air Pollutants (NESHAP). These amendments implement the plain language reading of the ``major source'' and ``area source'' definitions of section 112 of the Clean Air Act (CAA) and provide that a major source can be reclassified to area source status at any time upon reducing its potential to emit (PTE) hazardous air pollutants (HAP) to below the major source thresholds (MST) of 10 tons per year (tpy) of any single HAP and 25 tpy of any combination of HAP. This rule also finalizes amendments to clarify the compliance dates, notification, and recordkeeping requirements that apply to sources choosing to reclassify to area source status and to sources that revert back to major source status, including a requirement for electronic notification.
