          - [FRL-10020-15-OAR]

# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Notice of data availability.

# SUMMARY:

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 second round of allocations of allowances from the CSAPR new unit set-asides (NUSAs) for the 2020 control periods and has posted spreadsheets containing the calculations on EPA's website. EPA has also completed calculations for allocations of the remaining 2020 NUSA allowances to existing units and has posted spreadsheets containing those calculations on EPA's website as well.

# DATES:

February 11, 2021.

# FOR FURTHER INFORMATION CONTACT:

                        Questions concerning this action should be addressed to Jason Kuhns at (202) 564-3236 or                         *kuhns.jason@epa.gov*                         or Andrew Reighart at (202) 564-0418 or                         *reighart.andrew@epa.gov.*

# SUPPLEMENTARY INFORMATION:

                    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 December 21, 2020 (85 FR 83078), EPA provided notice of the preliminary identification of units eligible to receive second-round NUSA allocations for the 2020 control periods and described the process for submitting any objections. EPA received no objections in response to the December 21, 2020 NODA. This NODA provides notice of EPA's calculations of the amounts of the second-round 2020 NUSA allocations to the previously identified eligible new units and the allocations of the remaining allowances to existing units.                

                    The detailed unit-by-unit data and final allowance allocation calculations are set forth in Excel spreadsheets titled “CSAPR_NUSA_2020_NOX                    _Annual_2nd_Round_Final_Data_New_Units,” “CSAPR_NUSA_2020_NOx                    _OS_2nd_Round_Final_Data_New_Units,” “CSAPR_NUSA_2020_SO2                    _2nd_Round_Final_Data_New_Units,” “CSAPR_NUSA_2020_NOX                    _Annual_2nd_Round_Final_Data_Existing_Units,” “CSAPR_NUSA_2020_NOX                    _OS_2nd_Round_Final_Data_Existing_Units,” and “CSAPR_NUSA_2020_SO2                    _2nd_Round_Final_Data_Existing_Units”, available on EPA's website at                     *https://www.epa.gov/​csapr/​csapr-compliance-year-2020-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.

Authority: 40 CFR 97.411(b), 97.511(b), 97.611(b), 97.711(b), and 97.811(b).
