Environmental Protection Agency April 30, 2024 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is approving State Implementation Plan (SIP) revisions submitted by the State of New Hampshire. The revisions establish NOX reasonably available control technology (RACT) requirements for coal-fired cyclone boilers located in the state, portions of New Hampshire's NOX RACT certifications for the 2008 and 2015 ozone standards that pertain to requirements for coal-fired cyclone boilers, and withdrawal from the SIP of two previously issued RACT orders. This action is being taken in accordance with the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is proposing to approve a permitting rule which provides specific permit exemptions for sources otherwise requiring a permit, submitted as a revision to the San Diego County Air Pollution Control (APCD or "District") portion of the California State Implementation Plan (SIP). The proposed revisions would expand an existing provision that exempts tub grinders and trommel screens that process green material from permit requirements to include horizontal grinders and the processing of mixtures of green material and food material. The revisions also add a definition for "food material." This action is being taken pursuant to the Clean Air Act (CAA or "Act") and its implementing regulations. We are taking comments on this proposal and plan to follow with a final action.
