Availability of Data on Allocations of Cross-State Air Pollution Rule Allowances to Existing Electricity Generating Units

Through this notice of data availability (NODA), the EPA is providing notice of allocations of emission allowances to certain units for compliance with the Cross-State Air Pollution Rule (CSAPR). Since its original promulgation, CSAPR has been amended in several subsequent rulemakings and its compliance deadlines have been tolled by three years pursuant to an order of the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit or Court). These allowance allocations, which supersede the allocations announced in a 2011 NODA, reflect the changes to CSAPR made in those subsequent rulemakings as well as "re- vintaging" of previously recorded allowances so as to account for the impact of tolling of the rule's deadlines. The allocations apply only to units that commenced commercial operation before 2010 and only to the extent that states do not provide alternative allowance allocations following procedures set out in the rule. A spreadsheet containing both the allowance allocations and the data upon which the allocations are based has been posted on the EPA's Web site.
