Direct Final Rule

Revisions to Federal Implementation Plans to Reduce Interstate Transport of
Fine Particulate Matter and Ozone - Part II

ACTION

EPA is taking direct final action on several additional revisions to the final Cross-State Air
Pollution Rule (CSAPR). In a separate but related action today, the Agency also finalized
technical revisions to the CSAPR that were proposed on October 6, 2011. In that proposal, EPA
requested additional comment regarding state budgets and today's direct final rule addresses
comments received during that public comment process.

Like the revisions rule also finalized today, this direct final rule will provide important and
consistent technical adjustments to the CSAPR programs in certain states. No changes will be
made to the core elements of the program through this action.

CSAPR is a sound, achievable, market-based program that will deliver strong public health
protections. The revisions in this direct final rule will not affect the major air quality
improvements slated to occur under CSAPR. While individual state adjustments vary, overall,
the total budget increase from both rules remain small—around two percent—when compared
to the millions of tons of pollution reductions secured by CSAPR. CSAPR will significantly reduce
the interstate transport of pollution and help downwind states in their efforts to attain and
maintain the National Ambient Air Quality Standards (NAAQS).

Although the U.S. District Court of Appeals stayed the CSAPR pending judicial review, the
Agency believes that it is prudent to move forward with finalizing these corrections so EPA can
be prepared to implement the CSAPR if the stay is lifted. While this action revises the CSAPR, it
is consistent with, and is unaffected by, the Court's Order staying the underlying final CSAPR.
Finalizing this action in and of itself does not impose any requirements on regulated units or
states.

The direct final rule revises state budgets for Arkansas, Georgia, Indiana, Kansas, Louisiana,
Mississippi, Missouri, Nebraska, New York, Ohio, Oklahoma, South Carolina, and Texas. This rule
also revises new unit set-asides for Arkansas, Louisiana, and Missouri.

STATE BUDGETS AND NEW UNIT SET-ASIDES

Like the technical adjustments finalized in the related revisions rule, the adjustments outlined
in this direct final rule reflect updated information on pollution controls and operational
requirements at specific units subject to the CSAPR.

The revisions included in the direct final rule cover changes in the following areas:

BACKGROUND

EPA issued CAIR on May 12, 2005 and the CAIR federal implementation plans (FIPs) on April 26,
2006. In 2008, the U.S. Court of Appeals for the D.C. Circuit remanded CAIR to the Agency,
leaving existing CAIR programs in place while directing EPA to replace them as rapidly as
possible with a new rule consistent with the Clean Air Act.

The CSAPR was proposed July 6, 2010. EPA held three public hearings on the proposed rule
during the 60-day comment period. EPA also issued three notices of data availability (NODAs)
to provide additional opportunities for public comment on data, modeling, and other key
aspects of the rule. The Agency received hundreds of detailed comments from states,
environmental and public health groups, industry, and other stakeholders during the comment
periods for the proposed rule and NODAs. The final CSAPR was finalized on July 6, 2011.

In a separate but related regulatory action, EPA also issued a supplemental notice of proposed
rulemaking on July 6, 2011. The supplemental proposal was open for public review and
comment until August 22, 2011. No public hearing was requested. EPA finalized the
supplemental rule on December 15, 2011 to include five additional states - Iowa, Michigan,
Missouri, Oklahoma, and Wisconsin - in the CSAPR ozone season NOx program. EPA concluded
that these five states plus Kansas significantly contribute to nonattainment and/or interference
with maintenance of the 1997 ozone NAAQS in other states.

In order to make technical adjustments to the CSAPR based on new information, EPA proposed
a revisions rule on October 6, 2011. The public comment period ended on November 28, 2011
and a public hearing was held in Washington, DC on October 28, 2011. EPA is finalizing the
revisions rule today in a separate but related regulatory action.

The CSAPR was scheduled to replace CAIR starting January 1, 2012. However, on December 30,
2011, the U.S. Court of Appeals for the D.C. Circuit issued a ruling to stay the CSAPR pending
judicial review. While this decision delays implementation of the CSAPR and the significant
public health benefits associated with the rule, it also leaves CAIR in place while the court
considers the merits of the challenges to the CSAPR.

HOW TO COMMENT

EPA will accept comment on the parallel proposal that is being published concurrently with the
direct final rule. EPA will accept comment for 30 days after publication in the Federal Register.
If the Agency receives no significant adverse comment, the direct final will become effective 90
days after publication in the Federal Register. If EPA receives adverse comment, the Agency will
publish a timely withdrawal in the Federal Register. EPA would then review relevant comments
received on the parallel proposal before issuing a final rule.
