        <RULE_TITLE>Prevention of Air Pollution Emergency Episodes</RULE_TITLE>
        <ABSTRACT><![CDATA[EPA proposes to revise subpart H of 40 CFR part 51, which establishes the significant harm levels (SHL) for sulfur dioxide (SO2), particulate matter (PM), carbon monoxide (CO), nitrogen oxide (NO2), and ozone (O3), as well as the requirements for that portion of State implementation plan requirements to address air pollution emergency episodes. The proposal includes the following: (1) a new significant harm level for fine particulate matter (PM2.5), consistent with the July 18, 1997 revision of the addition of national ambient air quality standards (NAAQS) for particulate matter PM2.5; (2) revisions to the emergency episode requirements to simplify the emergency episode classification system for air quality control regions; (3) distinction between the classic type of mounting emergency episodes (which are occurring less and less due to the improvement of air quality nationwide over the last 30 years), and the catastrophic emergency episode caused by a process or pollution control equipment malfunction at a single air pollution source; (4) revisions to address pollutant transport; and (5) removal of Appendix L (an example State emergency episode regulation) from the Code of Federal Regulations in lieu of a more comprehensive guidance document. Since many areas today that are subject to the current emergency episode requirements are very unlikely to experience these types of episodes, EPA believes it is appropriate to update the emergency episode requirements to address current realities.]]></ABSTRACT>
