Mo. Code Regs. tit. 10 § 10-6.376

Current through Register Vol. 49, No. 20, October 15, 2024

Section 10 CSR 10-6.376 - Cross-State Air Pollution Rule Annual SO[2] Group 1 Trading Program

PURPOSE: The purpose of this rule is to have Missouri responsible for the Cross-State Air Pollution Rule (CSAPR) Sulfur Dioxide (SO₂) Group 1 Trading Program rather than the U.S. Environmental Protection Agency. This rule also provides the process to allocate allowances to affected units in Missouri for compliance with the CSAPR SO₂ Group 1 Trading Program. The purpose of this amendment is to adjust emission allowances pursuant to the CSAPR Sulfur Dioxide SO₂ Group 1 Trading Program. This amendment will return one thousand three hundred (1,300) allowances (tons) SO₂ emission allowances to Iatan Unit 1 from the Asbury Power Plant. The 2015 amendment to this rule reallocated these one thousand three hundred (1,300) allowances (tons) SO₂ emission allowances from Iatan Unit 1 to Asbury based on ownership share per a request from industry. Asbury is retired as of March 2020, and Liberty Utilities and Evergy have requested to transfer the one thousand three hundred (1,300) credits back to Iatan Unit 1 before they are forfeited to the new unit set-aside and redistributed to other emission units. This rulemaking reverses the 2015 reallocation of one thousand three hundred (1,300) allowances (tons) SO₂ emission allowances. Asbury's remaining three thousand one hundred eighty (3,180) allowances (tons) allowances will be transferred to the new unit set-aside and redistributed, as is the case for any unit that retires under the program. In addition, there is a minor administrative change clarifying the list of exceptions to this rule. Pursuant to section 536.016, RSMo, the evidence supporting the need for this proposed amendment is that 40 CFR 52.39(f)(6) requires the Department of Natural Resources to submit a SIP revision to EPA by December 1 of the year before the year in which the department sends the allowance allocations to EPA. Since Asbury did not operate in 2020, the allowance allocation submission set to be made in June 2022 will be the first submission where the one thousand three hundred (1,300) allowances (tons) emission allowances would be forfeited if not reallocated. Therefore, it is necessary to submit this amendment (SIP revision) to EPA by December 1, 2021.

Note: Being included or excluded on the list of sources in Table I does not constitute a determination that such source is or is not a CSAPR SO₂ Group 1 unit. The determination of applicability for CSAPR SO₂ Group 1 units is in 40 CFR 97.604 as incorporated by reference in subsection (1)(A) of this rule.

(B) New Units.

1. Annual Submittal. For the CSAPR SO₂ Group 1 control period in 2017 and each control period thereafter, the director must submit to EPA, in a format prescribed by the administrator, the CSAPR SO₂ Group 1 allowances as determined under this subsection by July 1 of the applicable control period.

2. New unit set-asides.

A. Allowance Calculation. Every year, the director will calculate the CSAPR SO₂ Group 1 allowance allocation to each CSAPR SO₂ Group 1 unit in a state, in accordance with subparagraphs (3)(B)3.B. through (3)(B)3.G. and (3)(B)3.L. of this rule, for the control period in the year of the applicable submittal deadline under paragraph (3)(B)1. of this rule. Once the calculations are complete, the director will contact all facilities that will receive allocations under subparagraphs (3)(B)3.B. through (3)(B)3.G. and (3)(B)3.L. of this rule for the control period in the year of the applicable submittal deadline under paragraph (3)(B)1. of this rule to confirm that the calculations were performed in accordance with this rule, and make adjustments to the calculations if necessary.

B. Excess Allowances. If the new unit set-aside for the control period has any CSAPR SO₂ Group 1 allowances remaining after the calculations performed under sub-paragraphs (3)(B)3.B. through (3)(B)3.G. and (3)(B)3.L. of this rule have been completed, then allowances will be calculated in accordance with subparagraph (3)(B)3.I. of this rule.

C. Industry Requests for Excess Allowances. If a facility owner, operator, or designated representative wishes to receive allowances in accordance with subparagraph (3)(B)3.I. of this rule, for any control period, then by April 5 of the applicable control period, the facility owner, operator, or designated representative must submit information to the director confirming that a CSAPR SO₂ Group 1 unit commenced commercial operation during the period starting January 1 of the year before the year of such control period and ending March 31 of the year of such control period. The submittal must also include the calculation of eligible allowances for use in subparagraph (3)(B)3.I. of this rule, for each CSAPR SO₂ Group 1 unit that commenced commercial operation during the period starting January 1 of the year before the year of such control period and ending March 31 of the year of such control period.

(I) The calculation of eligible allowances must be in accordance with part (3)(B)3.I.(III) of this rule in order for such units to be eligible to receive any allowances in accordance with subparagraph (3)(B)3.I. of this rule.

(II) Each year, the director will review any submissions made in accordance with this paragraph to confirm that units identified in the submissions are CSAPR SO₂ Group 1 units that commenced commercial operation during the period starting January 1 of the year before the year of such control period and ending March 31 of the year of such control period. The director will also confirm that the submission includes the correct calculations for eligible allowances in accordance with part (3)(B)3.I.(III) of this rule. If, during the review, the director identifies any discrepancies with the identified units or the calculations in a submission made in accordance with this paragraph, the director may request additional information from the facility owner, operator, or designated representative that made the submission. If additional information is requested, the facility owner, operator, or designated representative must provide the requested information by the deadline specified in the information request; otherwise, units identified in such submission will not be eligible for allowances in accordance with subparagraph (3)(B)3.I. of this rule for the applicable control period.

D. Public Notification. The director will determine the CSAPR SO₂ Group 1 allowance allocation to each CSAPR SO₂ Group 1 unit in accordance with subparagraphs (3)(B)3.I., (3)(B)3.J., and (3)(B)3.L. of this rule and 40 CFR 97.606(b)(2) and 40 CFR 97.630 through 40 CFR 97.635 as incorporated by reference in subsection (1)(A) of this rule. By June 1 of each year, the director will issue a notification making available the results of all allowance determinations from the new unit set-aside for the control period in which the notification is made.

(I) For each notification in subparagraph (3)(B)2.D. of this rule, the director will provide an opportunity for submission of objections to the calculations referenced in such notice.

(II) If there are objections, the director will review them and provide notification stating the outcome.

E. Allowance Changes. If any CSAPR SO₂ Group 1 allowances are added to the new unit set-aside after submittals per subparagraph (3)(B)2.C. of this rule, the director will issue additional notifications, as deemed appropriate, of the allocation of such CSAPR SO₂ Group 1 allowances in accordance with subparagraph (3)(B)3.J. of this rule.

3. New Unit Annual Allowance Allocation Methodology. For each control period in 2017 and thereafter and for the CSAPR SO₂ Group 1 units in Missouri, the director will allocate CSAPR SO₂ Group 1 allowances to the CSAPR SO₂ Group 1 units as follows:

A. Units Eligible to Receive Allowances. The CSAPR SO₂ Group 1 allowances will be allocated to the following CSAPR SO₂ Group 1 units, except as provided in subparagraph (3)(B)3.J. of this rule:

(I) CSAPR SO₂ Group 1 units that are not listed in Table I in paragraph (3)(A)2. of this rule;

(II) CSAPR SO₂ Group 1 units whose allocation of an amount of CSAPR SO₂ Group 1 allowances for such control period listed in Table I in paragraph (3)(A)2. of this rule is covered by 40 CFR 97.611(c)(2) or (3) as incorporated by reference in subsection (1)(A) of this rule;

(III) CSAPR SO₂ Group 1 units that are listed in Table I in paragraph (3)(A)2. of this rule and the allocation to such unit(s) is terminated for the applicable control period pursuant to paragraph (3)(A)2. of this rule, and that operate during the control period immediately preceding such control period; or

(IV) For purposes of subparagraph (3)(B)3.I. of this rule, CSAPR SO₂ Group 1 units under 40 CFR 97.611(c)(1)(ii) whose allocation of an amount of CSAPR SO₂ Group 1 allowances for such control period under paragraph (3)(B)2. of this rule is covered by 40 CFR 97.611(c)(2) or (3) as incorporated by reference in subsection (1)(A) of this rule;

B. Total Allowances Available. The director will establish a separate new unit set-aside for the state for each such control period. Each such new unit set-aside will be allocated CSAPR SO₂ Group 1 allowances in an amount equal to the difference between the Missouri CSAPR SO₂ Group 1 trading budget for 2017 and thereafter, as set forth in 40 CFR 97.610(a) as incorporated by reference in subsection (1)(A) of this rule, and the total number of allowances allocated in accordance with paragraph (3)(A)1. of this rule for such control period. The new unit set-aside will be allocated additional CSAPR SO₂ Group 1 allowances (if any) in accordance with paragraph (3)(A)2. of this rule and 40 CFR 97.611(c)(5) as incorporated by reference in subsection (1)(A) of this rule;

C. Eligible Control Periods. The director will determine, for each CSAPR SO₂ Group 1 unit described in sub-paragraph (3)(B)3.A. of this rule, an allocation of CSAPR SO₂ Group 1 allowances for the later of the following control periods and for each subsequent control period:

(I) The control period in 2017;

(II) The first control period after the control period in which the CSAPR SO₂ Group 1 unit commences commercial operation;

(III) For a unit described in part (3)(B)3.A.(II) of this rule, the first control period in which the CSAPR SO₂ Group 1 unit operates in the state after operating in another jurisdiction and for which the unit is not already allocated one (1) or more CSAPR SO₂ Group 1 allowances; and

(IV) For a unit described in part (3)(B)3.A.(III) of this rule, the first control period after the control period in which the unit resumes operation, or the first control period in which the allocation for such unit listed in Table I in paragraph (3)(A)2. of this rule is terminated pursuant to paragraph (3)(A)2. of this rule, whichever is later;

D. Allocations. The allocation to each CSAPR SO₂ Group 1 unit described in parts (3)(B)3.A.(I) through (3)(B)3.A.(III) of this rule and for each control period described in subparagraph (3)(B)3.C. of this rule will be an amount equal to the unit's total tons of SO₂ emissions during the immediately preceding control period. The director will adjust the allocation amount in this subparagraph in accordance with subparagraphs (3)(B)3.E. through (3)(B)3.G. and (3)(B)3.L. of this rule;

E. Sum of Allowances. The director will calculate the sum of the CSAPR SO₂ Group 1 allowances determined for all such CSAPR SO₂ Group 1 units under subparagraph (3)(B)3.D. of this rule in the state for such control period;

F. Extra Allowance Allocation. If the amount of CSAPR SO₂ Group 1 allowances in the new unit set-aside for the state for such control period is greater than or equal to the sum under subparagraph (3)(B)3.E. of this rule, then the director will allocate the amount of CSAPR SO₂ Group 1 allowances determined for each such CSAPR SO₂ Group 1 unit under subparagraph (3)(B)3.D. of this rule;

G. Insufficient Allowance Allocation. If the amount of CSAPR SO₂ Group 1 allowances in the new unit set-aside for the state for such control period is less than the sum under sub-paragraph (3)(B)3.E. of this rule, then the director will allocate to each such CSAPR SO₂ Group 1 unit the amount of the CSAPR SO₂ Group 1 allowances determined under subparagraph (3)(B)3.D. of this rule for the unit, multiplied by the amount of CSAPR SO₂ Group 1 allowances in the new unit set-aside for such control period, divided by the sum under subparagraph (3)(B)3.E. of this rule, and rounded to the nearest allowance;

H. Confirmation of Allowances. The director will contact facilities as described in subparagraph (3)(B)2.A. of this rule to confirm the amount of CSAPR SO₂ Group 1 allowances allocated under subparagraphs (3)(B)3.B. through (3)(B)3.G. and (3)(B)3.L. of this rule for such control period to each CSAPR SO₂ Group 1 unit eligible for such allocation;

I. Allowance Calculation for Units That Recently Began Operation. If, after completion of the procedures under subparagraphs (3)(B)3.E. through (3)(B)3.H. of this rule for such control period, any unallocated CSAPR SO₂ Group 1 allowances remain in the new unit set-aside for the state for such control period, the director will allocate such CSAPR SO₂ Group 1 allowances as follows:

(I) For any submission made in accordance with subparagraph (3)(B)2.C. of this rule, the submitting facility owner, operator, or designated representative may include the calculation of eligible allowances for such control period as specified in part (3)(B)3.I.(III) of this rule. If such submission is not made or fails to include the calculation of eligible allowances under this part by the April 5 deadline, or if the facility owner, operator, or designated representative fails to provide additional information requested in accordance with part (3)(B)2.C.(II) of this rule by the applicable deadline; then no allowances will be awarded to such unit in accordance with this sub-paragraph for such control period;

(II) The director will review submissions made in accordance with subparagraph (3)(B)2.C. of this rule, as specified in part (3)(B)2.C.(II) of this rule and may adjust the units identified in such submission if they are not eligible for allowances under this subparagraph, and the director may also adjust the calculation of eligible allowances included in such submission to ensure they are in accordance with part (3)(B)3.I.(III) of this rule;

(III) The calculation of eligible CSAPR SO₂ Group 1 allowances for a specific control period for CSAPR SO₂ Group 1 units that commenced commercial operation during the period starting January 1 of the year before the year of such control period and ending March 31 of the year of such control period must be as follows;

(IV) The director will determine, for each unit described in subparagraph (3)(B)3.A. of this rule that commenced commercial operation during the period starting January 1 of the year before the year of such control period and ending March 31 of the year of such control period, the positive difference (if any) between the unit's emissions during the previous control period and the amount of eligible CSAPR SO₂ Group 1 allowances as calculated under part (3)(B)3.I.(III) of this rule;

(V) The director will determine the sum of the positive differences determined under part (3)(B)3.I.(IV) of this rule;

(VI) If the amount of unallocated CSAPR SO₂ Group 1 allowances remaining in the new unit set-aside for the state for such control period is greater than or equal to the sum determined under part (3)(B)3.I.(V) of this rule, then the director will allocate the amount of CSAPR SO₂ Group 1 allowances determined for each such CSAPR SO₂ Group 1 unit under part (3)(B)3.I.(IV) of this rule; and

(VII) If the amount of unallocated CSAPR SO₂ Group 1 allowances remaining in the new unit set-aside for the state for such control period is less than the sum under part (3)(B)3.I.(V) of this rule, then the director will allocate to each such CSAPR SO₂ Group 1 unit the amount of the CSAPR SO₂ Group 1 allowances determined under part (3)(B)3.I.(IV) of this rule for the unit, multiplied by the amount of unallocated CSAPR SO₂ Group 1 allowances remaining in the new unit set-aside for such control period, divided by the sum under part (3)(B)3.I.(V) of this rule, and rounded to the nearest allowance;

J. Distribution of Remaining Allocations. If, after completion of the procedures under subparagraphs (3)(B)3.I. and (3)(B)3.L. of this rule for such control period, any unallocated CSAPR SO₂ Group 1 allowances remain in the new unit set-aside for the state for such control period, the director will allocate to each CSAPR SO₂ Group 1 unit that is in the state, is allocated an amount of CSAPR SO₂ Group 1 allowances listed in Table I in paragraph (3)(A)2. of this rule, and continues to be allocated CSAPR SO₂ Group 1 allowances for such control period in accordance with paragraph (3)(A)2. of this rule, an amount of CSAPR SO₂ Group 1 allowances equal to the following: the total amount of such remaining unallocated CSAPR SO₂ Group 1 allowances in such new unit set-aside, multiplied by the unit's allocation listed in Table I in paragraph (3)(A)2. of this rule for such control period, divided by the remainder of the amount of tons in the applicable state SO₂ Annual trading budget minus the amount of tons in such new unit set-aside for the state for such control period, and rounded to the nearest allowance;

The director will list the CSAPR SO₂ Group 1 units in descending order based on the amount of such units' allocations under subparagraph (3)(B)3.G., part (3)(B)3.I.(VII), or subparagraph (3)(B)3.J. of this rule, as applicable, and, in cases of equal allocation amounts, in alphabetical order of the relevant source's name and numerical order of the relevant unit's identification number, and will reduce each unit's allocation under subparagraph (3)(B)3.G., part (3)(B)3.I.(VII), or subpara-graph (3)(B)3.J. of this rule, as applicable, by one (1) CSAPR SO₂ Group 1 allowance (but not below zero (0)) in the order in which the units are listed and will repeat this reduction process as necessary, until the total allocations of such new unit set-aside equal the total amount of such new unit set-aside.

(II) Notwithstanding the requirements of subparagraphs (3)(B)3.J. and (3)(B)3.K. of this rule, if the calculations of allocations of a new unit set-aside for a control period in a given year under subparagraph (3)(B)3.F., part (3)(B)3.I.(VI), and subparagraph (3)(B)3.J. of this rule would otherwise result in a total allocations of such new unit set-aside less than the total amount of such new unit set-aside, then the director will adjust the results of the calculations under subparagraph (3)(B)3.J. of this rule, as follows. The director will list the CSAPR SO₂ Group 1 units in descending order based on the amount of such units' allocations under sub-paragraph (3)(B)3.J. of this rule and, in cases of equal allocation amounts, in alphabetical order of the relevant source's name and numerical order of the relevant unit's identification number, and will increase each unit's allocation under subparagraph (3)(B)3.J. of this rule by one (1) CSAPR SO₂ Group 1 allowance in the order in which the units are listed and will repeat this increase process as necessary, until the total allocations of such new unit set-aside equal the total amount of such new unit set-aside.
