SUPPLEMENTARY INFORMATION:

I. Data for Which Notice Is Being Provided

Through this NODA, the EPA is providing notice of the availability of unit-specific default allocations of CSAPR allowances for electricity generating units (EGUs) that commenced commercial operation before 2010. The data are contained in an Excel spreadsheet titled “Unit Level Allocations Under the CSAPR FIPs After Tolling” that has been posted on the EPA's Web site at http://www.epa.gov/​crossstaterule/​actions.html. The spreadsheet contains default allocations of allowances under each of the four CSAPR trading programs for individual EGUs for each compliance year from 2015 through 2020. The spreadsheet also contains the data used to compute the allocations and describes how the computations are performed. The EPA is not requesting comment on the allocations, underlying data, or computation methodology.

The EPA notes that an allocation or lack of allocation of emission allowances to a given EGU does not constitute a determination that CSAPR does or does not apply to the EGU.^[1] The EPA also notes that allocations are subject to potential correction under the rule.^[2]

II. Description of the Allocations

CSAPR includes several emissions trading programs that require affected EGUs to hold emission allowances sufficient to cover their emissions of nitrogen oxides (NO_X) and/or sulfur dioxide (SO₂ ) in each compliance period. For each trading program and compliance period, the rule establishes overall state “budgets” representing the maximum number of emission allowances that may be allocated to the group of affected EGUs in each covered state. Beginning with CSAPR's second compliance year, each covered state generally has the option to determine how the allowances in its state budget for each program should be allocated among the state's EGUs.^[3] However, for CSAPR's first compliance year, and by default for subsequent compliance years in situations where a state has not provided the EPA with the state's own allocations pursuant to an approved SIP revision, the allocations are made by the EPA.

In the case of units commencing commercial operation on or after January 1, 2010, termed “new” units, the EPA's default allocations for each compliance year are annually determined during the compliance year based on current and prior year emission data, using a methodology set out in the regulatory text.^[4] In the case of units that commenced commercial operations before January 1, 2010, termed “existing” units, the EPA determined default allocations for all compliance years during the initial rulemaking based on 2006-2010 heat input data and 2003-2010 emissions data, according to a methodology finalized in the rulemaking but not included in the regulatory text.^[5] The regulatory text calls for default allocations to the existing units to be provided in a NODA.^[6] In July 2011, the EPA issued a NODA reflecting the default allocations for existing units as determined in the original CSAPR rulemaking.^[7]

In three rulemakings finalized after the original CSAPR rulemaking, the EPA created budgets for several states added to the rule's ozone-season NO_X trading program, increased some previously established state budgets, and changed the shares of some state budgets set aside for new units.^[8] In one of those rulemakings, the EPA also revised unit-specific allowance allocations in some states in order to account for emissions tonnage limitations established under certain consent decrees.^[9]

As originally promulgated, compliance with CSAPR's trading programs was scheduled to begin on January 1, 2012. However, on December 30, 2011, the D.C. Circuit stayed the rule. On October 23, 2014, the Court granted the EPA's motion to lift the stay and toll the rule's compliance deadlines by three years, allowing the first compliance period to begin on January 1, 2015.^[10]

The allowance allocations described in this NODA reflect all the budget, set-aside, and unit-specific allocation changes finalized in the rulemakings conducted after the original CSAPR rulemaking. The allocations also account for the impact of the tolling of the rule's compliance deadlines by re-vintaging previously recorded 2012 and 2013 allowances as 2015 and 2016 allowances, respectively.

III. Recordation of the Allocations

CSAPR specifies deadlines for the EPA to record allowance allocations for each compliance year.^[11] In cases where those deadlines, as tolled by the Court's order, have not yet passed, and where states have not submitted alternative allowance allocations pursuant to approved SIP revisions, the EPA will record the allocations described in this NODA by the applicable recordation deadlines.

To meet recordation deadlines that occurred before CSAPR was stayed, the EPA has already recorded most allowances allocated for CSAPR's first compliance year (originally 2012 and now 2015), and some allowances allocated for CSAPR's second ( printed page 71676) compliance year (originally 2013 and now 2016). In these cases, the EPA will re-vintage the previously recorded 2012 and 2013 allowances into 2015 and 2016 allowances, respectively, consistent with the Court's order tolling CSAPR's compliance deadlines. The EPA will then record adjustments as needed to bring the re-vintaged, previously recorded allocations up to the 2015 and 2016 allocations described in this NODA. Allowance tracking system accounts will be briefly frozen while the re-vintaging and adjustments are carried out.
