Environmental Protection Agency July 24, 2018 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Northern Sonoma County Air Pollution Control District (NSCAPCD or District) portion of the California State Implementation Plan (SIP). These revisions concern the District's prevention of significant deterioration (PSD) permitting program for new and modified sources of air pollution. We are approving local rules under the Clean Air Act (CAA or the Act).

EPA is providing notice that it is supplementing the record for the proposed Risk Management Program (RMP) Reconsideration rule published on May 30, 2018. We have placed into the rulemaking docket the November 2017 version of the RMP database containing risk management plans submitted to EPA. EPA used this version to support analysis of changes in the RMP reporting facility universe discussed in the Regulatory Impact Analysis of the proposed Reconsideration rule. To afford the public an opportunity to comment on the updated RMP database and its impacts on the proposed Reconsideration rule, EPA is extending the comment period for the proposed rule.
