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 to Missouri. 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 evidence supporting the need for this rule, per section 536.016, RSMo, is a November 7, 2011 email between Empire District Electric Co. (Empire) and Kansas City Power and Light (KCP&L) and the November 26, 2014, March 24, 2015, and February 8, 2018 affected industry meeting summaries.

control period has any CSAPR SO2 Group 1 allowances remaining after the calculations performed under subparagraphs (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.

1. 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.

1. (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.

1. (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.

1. 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.
