# 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 preliminary 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. EPA will consider timely objections to the data and calculations before making final determinations of the amounts of additional allowances that must be surrendered.                    

# DATES:

Objections to the information referenced in this notice must be received on or before August 15, 2022.

# ADDRESSES:

                        Submit your objections via email to                         *CSAPR@epa.gov.*                         Include “2021 CSAPR Assurance Provisions” in the email subject line and include your name, title, affiliation, address, phone                               ( print page 42460)                            number, and email address in the body of the email.

                        Questions concerning this action should be addressed to Garrett Powers at (202) 564-2300 or                         *powers.jamesg@epa.gov.*

# 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. Applying the procedures in the regulations for the 2021 control period, EPA has completed preliminary calculations indicating that responsibility for surrendering 1,295 additional allowances in Missouri should be apportioned almost entirely to the group of units operated by Associated Electric Cooperative, Inc., with much smaller shares apportioned to the groups of units operated by the municipal utilities of Chillicothe and Higginsville.                

In this document, EPA is providing notice of the data relied on to determine the amounts of the exceedance of the Missouri assurance level discussed above and notice of 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, as required under 40 CFR 97.825(b)(1)(ii). By October 1, 2022, EPA will provide notice of the final calculations of the amounts of additional allowances that must be surrendered, incorporating any adjustments made in response to objections received, as required under 40 CFR 97.825(b)(2)(ii). Each set of owners and operators identified pursuant to the notice of the final calculations must hold the required additional allowances in an assurance account by November 1, 2022.

                    The data and preliminary calculations are set forth in an Excel spreadsheet entitled “2021_CSAPR_assurance_provision_calculations_prelim.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 each state and the amounts by which the total reported NOX                     emissions exceeded the respective states' assurance levels 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 each 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.                

Any objections should be strictly limited to whether EPA has identified the data and performed the calculations in the spreadsheet correctly in accordance with the regulations. Objections must include (1) precise identification of the specific data or calculations the commenter believes are inaccurate, (2) new proposed data or calculations upon which the commenter believes EPA should rely instead, and (3) the reasons why EPA should rely on the commenter's proposed data or calculations and not the data and calculations referenced in this notice.
