Abstract:
On July 16, 1997, the President issued a memorandum to EPA on the
implementation of the revised air quality standards for ozone and
PM. The purpose of the attached document is to provide guidance on
implementing the revised ozone and PM NAAQS and the regional haze
program consistent with the Clean Air Act and the President's memorandum.
This draft replaces the draft of August 14, 1998. It includes guidance
to replace the "placeholders" of the August draft. As a result of
providing guidance for the placeholder sections, it also includes
a number of changes to certain other parts of the draft guidance.
For the revised ozone NAAQS, the guidance covers a classification
scheme, including relevant action dates for the planning process;
a policy clarifying the requirement that States adopt reasonably available
control requirements and reasonably available control technology (RACM/RACT)
into ozone nonattainment area SIPs for the ozone standard; and
details on the SIP requirements for ozone nonattainment areas (transitional,
traditional and international transport).
For the revised PM10 NAAQS, the guidance covers a classification scheme
for the revised PM10 NAAQS including relevant dates for the planning
process; SIP requirements for serious and moderate areas under the
revised PM10 NAAQS; and a clarification of the requirement that States
adopt RACM/RACT into PM nonattainment area SIPs.
For the PM2.5 NAAQS, because of the longer timeframe for collecting
monitoring data, designating nonattainment areas and developing SIPs,
the guidance notes where technical and other guidance is still under
development. In certain cases, however, principles relating to implementing
the PM2.5 NAAQS are provided.
For the PM2.5 NAAQS and the regional haze program, the guidance provides
placeholders for the additional guidance that EPA plans to issue after
final rulemaking on the regional haze rule; that guidance will address
inter-program coordination and an update on regional modeling.
