ENVIRONMENTAL PROTECTION AGENCY

[FRL-10009-58-OAR]


Administration of Cross-State Air Pollution Rule Trading Program 
Assurance Provisions for 2019 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 2019. Total emissions of nitrogen 
oxides (NOX) reported by Mississippi units participating in 
the CSAPR NOX Ozone Season Group 2 Trading Program during 
the 2019 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 Mississippi 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 July 1, 2020.

ADDRESSES: Submit your objections via email to CSAPR@epa.gov. Include 
``2019 CSAPR Assurance Provisions'' in the email subject line and 
include your name, title, affiliation, address, phone number, and email 
address in the body of the email.

FOR FURTHER INFORMATION CONTACT: Questions concerning this notice 
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 2019 control period, Mississippi units 
participating in the CSAPR NOX Ozone Season Group 2 Trading 
Program collectively reported emissions that exceed the state's 
assurance level under the program by 473 tons, resulting in a 
requirement for the surrender of 946 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 2019 control period for Mississippi, EPA has completed 
preliminary calculations indicating that responsibility for 
surrendering 946 additional allowances should be apportioned entirely 
to the group of units operated by Mississippi Power Company, all of 
which are represented by one common designated representative.
    In this document, EPA is providing notice of the data relied on to 
determine the amount of the exceedance of the Mississippi assurance 
level discussed above, as required under 40 CFR 97.825(b)(1)(ii), and 
notice of the preliminary calculations of the amounts of additional 
allowances that the owners and operators of certain Mississippi units 
must surrender as a result of the exceedance, as required under 40 CFR 
97.825(b)(2)(ii).\1\ By October 1, 2020,

[[Page 29446]]

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)(iii)(B). 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 
2, 2020.
---------------------------------------------------------------------------

    \1\ The regulations allow the notice of data availability 
required under 40 CFR 97.825(b)(2)(ii) to be published approximately 
two months after the notice of data availability required under 40 
CFR 97.825(b)(1)(ii), but in this instance EPA already has all the 
information needed to prepare both of the required notices and is 
therefore combining the two required notices into this single 
document.
---------------------------------------------------------------------------

    The data and preliminary calculations are set forth in an Excel 
spreadsheet entitled 
``2019_CSAPR_assurance_provision_calculations_prelim.xlsx'' available 
at http://www.epa.gov/csapr/csapr-assurance-provision-nodas. The 
spreadsheet contains data for the 2019 control period showing, for each 
Mississippi 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 2019 control period showing the total 
NOX emissions reported by all such units 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 2019 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.
    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.

    Authority: 40 CFR 97.825(b).
