Cross-State Air Pollution Rule (CSAPR)
Bulletins
May 11, 2012 - On May 10, 2012, EPA withdrew the Direct Final Revisions Rule (77 FR 10342, February 21, 2012). The Agency issued a parallel proposal (77 FR 10350, February 21, 2012) along with the direct final rule proposing the same revisions and will take final action on the proposed revisions rule expeditiously. The withdrawal does not affect the Final CSAPR Revisions Rule (77 FR 10324, February 21, 2012). 
April 20, 2012 - EPA has reviewed the comments submitted in response to the Direct Final Revisions Rule. EPA intends to withdraw the Direct Final Revisions Rule prior to its effective date and take final action on the proposed revisions rule expeditiously.
March 1, 2012 - EPA filed its brief on the merits of the legal challenges to the CSAPR. EPA's brief defends the rule and sets forth the reasons why the rule should be upheld by the court.
February 7, 2012 - EPA issued two sets of minor adjustments to the Cross-State Air Pollution Rule (CSAPR). These final rules maintain the significant health benefits of CSAPR, while making minor technical adjustments based on the latest and best data to ensure a smooth transition for utilities. The adjustments provide flexibility to states by increasing budgets in seventeen states and easing limits on market-based compliance options.
January 26, 2012 - EPA signed a notice, which will be published in the Federal Register, indicating that the Agency will not require compliance with the CSAPR
supplemental rule while the stay is in effect. EPA finalized the supplemental rule on December 15, 2011 to include five additional states - Iowa, Michigan, Missouri, Oklahoma, and Wisconsin - in the ozone season NOX program in the CSAPR.
January 10, 2012 - EPA has returned the vintage 2012 CAIR allowances to allowance accounts. Additional allocations of 2012 allowances will be done as soon as the allocation files are submitted to EPA by the states. States who have not yet submitted 2012 CAIR allocation files should send them to Paula Branch (branch.paula@epa.gov). If market participants wish to use the CAMD Business System to record transfers of the CSAPR allowances or to record other CSAPR related information, they may do so although they are not required to at this time.
December 30, 2011 - The United States Court of Appeals for the D.C. Circuit issued its ruling to stay the CSAPR pending judicial review. The court's decision is not a decision on the merits of the rule. EPA is ensuring the transition back to the Clean Air Interstate Rule (CAIR) occurs as seamlessly as possible.
