[FRL-8956-03-OAR]

Administration of Cross-State Air Pollution Rule Trading Program 
Assurance Provisions for 2021 Control Periods

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 the administration of the assurance 
provisions of the Cross-State Air Pollution Rule (CSAPR) trading 
programs for the control periods in 2021. Total emissions of nitrogen 
oxides (NOX) reported by Missouri units participating in the 
CSAPR NOX Ozone Season Group 2 Trading Program during the 
2021 control period exceeded the state's assurance level under the 
program. Data demonstrating the exceedance and EPA's final calculations 
of the amounts of additional allowances that the owners and operators 
of certain Missouri units must surrender have been posted in a 
spreadsheet on EPA's website.

DATES: September 21, 2022.

should be addressed to Garrett Powers at (202) 564-2300 or 
[email protected].

SUPPLEMENTARY INFORMATION: The regulations for each CSAPR trading 
program contain ``assurance provisions'' designed to ensure that the 
emissions reductions required from each state covered by the program 
occur within the state. If the total emissions from a given state's 
affected units exceed the state's assurance level under the program, 
then two allowances must be surrendered for each ton of emissions 
exceeding the assurance level (in addition to the ordinary obligation 
to surrender one allowance for each ton of emissions). In the quarterly 
emissions reports covering the 2021 control period, Missouri units 
participating in the CSAPR NOX Ozone Season Group 2 Trading 
Program reported emissions that exceed the state's assurance level 
under the program by 1,295 tons, resulting in a requirement for the 
surrender of 2,590 additional allowances.
    When a state's assurance level is exceeded, responsibility for 
surrendering the required additional allowances is apportioned among 
groups of units in the state represented by ``common designated 
representatives'' based on the extent to which each such group's 
emissions exceeded the group's share of the state's assurance level. 
For the CSAPR NOX Ozone Season Group 2 Trading Program, the 
procedures are set forth at 40 CFR 97.802 (definitions of ``common 
designated representative,'' ``common designated representative's 
assurance level,'' and ``common designated representative's share''), 
97.806(c)(2), and 97.825.
    On July 15, 2022, EPA published a document in the Federal Register 
providing notice of the data relied on to determine the amount of the 
exceedance of the Missouri assurance level and the preliminary 
calculations of the amounts of additional allowances that the owners 
and operators of certain Missouri units must surrender as a result of 
the exceedance and describing the process for submitting any objections 
(87 FR 42459). EPA received no written submissions objecting to the 
data and preliminary calculations.
    In this document, EPA is providing notice of the final calculations 
of the amounts of additional allowances that must be surrendered. 
Responsibility for surrendering 2,590 additional allowances for the 
Missouri exceedance has been apportioned almost entirely to the group 
of units operated by Associated Electric Cooperative, Inc. (2,570 
allowances), with much smaller shares apportioned to the groups of 
units operated by the municipal utilities of Chillicothe and 
Higginsville (4 and 16 allowances, respectively). Each set of owners 
and operators identified pursuant to this notice of the final 
calculations must hold the required additional allowances in an 
assurance account by November 1, 2022.
    The data and final calculations are set forth in an Excel 
spreadsheet entitled 
``2021_CSAPR_assurance_provision_calculations_final.xlsx'' available at 
http://www.epa.gov/csapr/csapr-assurance-provision-nodas. The 
spreadsheet contains data for the 2021 control period showing, for each 
Missouri unit identified as affected under the CSAPR NOX 
Ozone Season Group 2 Trading Program, the amount of NOX 
emissions reported by the unit and the amount of CSAPR NOX 
Ozone Season Group 2 allowances allocated to the unit, including any 
allowances allocated from a new unit set-aside. The spreadsheet also 
contains calculations for the 2021 control period showing the total 
NOX emissions reported by all such units in the state and 
the amount by which the total reported NOX emissions 
exceeded the state's assurance level under the program. Finally, the 
spreadsheet also includes calculations for the 2021 control period 
showing, for each common designated representative for a group of such 
units in the state, the common designated representative's share of the 
total reported NOX emissions, the common designated 
representative's share of the state's assurance level, and the amount 
of additional CSAPR NOX Ozone Season Group 2 allowances that 
the owners and operators of the units in the group must surrender.
