Start Preamble


Environmental Protection Agency (EPA).


Notice of data availability.


The Environmental Protection Agency (EPA) is providing notice of the availability of data on emission allowance allocations to certain units under the Cross-State Air Pollution Rule (CSAPR) trading programs. EPA has completed final calculations for the first round of allocations of allowances from the CSAPR new unit set-asides (NUSAs) for the 2019 control periods and has posted spreadsheets containing the calculations on EPA's website.

Under each CSAPR trading program where EPA is responsible for determining emission allowance allocations, a portion of each state's emissions budget for the program for each control period is reserved in a NUSA (and in an additional Indian country NUSA in the case of states with Indian country within their borders) for allocation to certain units that would not otherwise receive allowance allocations. The procedures for identifying the eligible units for each control period and for allocating allowances from the NUSAs and Indian country NUSAs to these units are set forth in the CSAPR trading program regulations at 40 CFR 97.411(b) and 97.412 (NOX Annual), 97.511(b) and 97.512 (NOX Ozone Season Group 1), 97.611(b) and 97.612 (SO2 Group 1), 97.711(b) and 97.712 (SO2 Group 2), and 97.811(b) and 97.812 (NOX Ozone Season Group 2). Each NUSA allowance allocation process involves up to two rounds of allocations to eligible units, termed “new” units, followed by the allocation to “existing” units of any allowances not allocated to new units.

In a notice of data availability (NODA) published in the Federal Register on May 28, 2019 (84 FR 24506), EPA provided notice of preliminary calculations for the first-round 2019 NUSA allowance allocations and described the process for submitting any objections. The only objection EPA received in response to the May 28, 2019 NODA was subsequently withdrawn. This NODA concerns the final calculations for the first round of 2019 NUSA allocations, which are unchanged from the preliminary calculations.

The detailed unit-by-unit data and final allowance allocation calculations are set forth in Excel spreadsheets titled “CSAPR_NUSA_2019_NOx_Annual_1st_Round_Final_Data”, “CSAPR_NUSA_2019_NOx_OS_1st_Round_Final_Data”, and “CSAPR_NUSA_2019_SO2_1st_Round_Final_Data”, available on EPA's website at​csapr/​csapr-compliance-year-2019-nusa-nodas.

EPA notes that an allocation or lack of allocation of allowances to a given unit does not constitute a determination that CSAPR does or does not apply to the unit. EPA also notes that, under 40 CFR 97.411(c), 97.511(c), 97.611(c), 97.711(c), and 97.811(c), allocations are subject to potential correction if a unit to which allowances have been allocated for a given control period is not actually an affected unit as of the start of that control period.
