Environmental Protection Agency May 19, 2009 – Federal Register Recent Federal Regulation Documents

The Environmental Protection Agency published in the Federal Register of April 29, 2009 (74 FR 19480), a document concerning Pennsylvania's Final Authorization of State Hazardous Waste Management Program Revisions. This document corrects the Docket Number.

EPA is finalizing amendments to the Exceptional Events Rule to provide a revised exceptional event data flagging and documentation schedule for ozone data that may be used for designations under the 2008 ozone National Ambient Air Quality Standards (NAAQS). The Exceptional Events Rule states that when EPA sets a NAAQS for a new pollutant or revises the NAAQS for an existing pollutant, EPA may revise or set a new schedule for flagging data for those NAAQS. EPA recently revised the primary and secondary ozone NAAQS to protect public health and welfare; the revised standards became effective May 27, 2008. Consistent with the process envisioned in the Exceptional Events Rule, this final rule revises the dates for flagging data and submitting documentation regarding exceptional events under the revised ozone NAAQS. This revised schedule allows EPA to fully consider State requests for exceptional event concurrence prior to EPA making final designations.

EPA is finalizing updates to the Code of Federal Regulations (CFR) delegation tables to reflect the current delegation status of New Source Performance Standards (NSPS) and National Emission Standards for Hazardous Air Pollutants (NESHAP) in Arizona, California, Hawaii, and Nevada.
