(a) Applicability. - (i) Section 3 of this Chapter applies to all stationary sources with actual emissions of 100 tons per year or more of sulfur dioxide in calendar year 2000 or any subsequent year.
- (ii) Except as provided in (iii) and (iv), any source that meets the criteria of (i) that emits less than 100 tons per year in any subsequent year shall remain subject to the requirements of Section 3 of this Chapter until 2018 or until the first control period under the Western Backstop Sulfur Dioxide Trading Program as established in Section 2 of this Chapter, whichever is earlier.
- (iii) A stationary source that meets the requirements of (i) that has permanently ceased operation is exempt from the requirements of Chapter 14.
(b) Annual Sulfur Dioxide Emission Report. - (i) Except as provided in (ii), each source subject to Chapter 14 shall report sulfur dioxide emissions by April 15th of each calendar year, in accordance with the schedule cited in Section 3(b)(iii), below.
- (ii) Each source subject to Chapter 14 that is also subject to 40 CFR part 75 reporting requirements, shall submit a summary report of annual sulfur dioxide emissions that were reported to the Environmental Protection Agency under 40 CFR part 75.
- (iii) Each source subject to Chapter 14 shall report emissions for the year 2003 by April 15, 2004, and annually thereafter. The inventory shall be submitted in the format specified by the Division of Air Quality.
- (iv) For the reports cited in (i) and (ii) of this section, each source subject to Chapter 14 shall document the emissions monitoring/estimation methodology used to calculate their sulfur dioxide emissions, and demonstrate that the selected methodology is acceptable under the inventory program.
- (v) For the reports cited in (i) and (ii) of this section, each source subject to Chapter 14 shall include emissions from startup, shut down, and upset conditions in the annual total inventory.
- (vi) For the reports cited in (i) and (ii) of this section, each source subject to Chapter 14 shall use 40 CFR part 75 methodology for reporting emissions for all sources subject to the federal acid rain program.
- (vii) For the reports cited in (i) and (ii) of this section, each source subject to Chapter 14 shall maintain all records used in the calculation of the emissions, including but not limited to the following:
- (A) amount of fuel consumed;
- (B) percent sulfur content of fuel and how the content was determined;
- (C) quantity of product produced;
- (D) emissions monitoring data;
- (F) how the emissions are calculated
- (viii) For the reports cited in (i) and (ii) of this section, each source subject to Chapter 14 shall maintain records of any physical changes to facility operations or equipment, or any other changes (e.g., raw material or feed) that may affect the emissions projections.
- (ix) For the reports cited in (i) and (ii) of this section, each source subject to Chapter 14 shall retain records for a minimum of ten years from the date of establishment, or if the record was the basis for an adjustment to the milestone, 5 years after the date of an implementation plan revision, whichever is longer.
(c) Changes in Emission Measurement Techniques. - (i) Each source subject to this Rule that uses a different emission monitoring or calculation method than was used to report their sulfur dioxide emissions in 2006 under Chapter 14, Section 3 shall adjust their reported emissions to be comparable to the emission monitoring or calculation method that was used in 2006. The calculations that are used to make this adjustment shall be included with the annual emission report under Section 3(b) of this Chapter.
(d) Notwithstanding any other provision of Chapter 14, Basin Electric Power Cooperative's Laramie River Station shall report its annual sulfur dioxide emissions as follows: for Laramie River Station Unit 1, Basin Electric Power Cooperative shall report its sulfur dioxide emissions based on an annual average emission rate of 0.159 lb/MMBtu multiplied by the actual annual heat input; for Laramie River Station Unit 2, Basin Electric Power Cooperative shall report its annual sulfur dioxide emissions based on an annual emission rate 0.162 lb/MMBtu multiplied by the actual annual heat input. Heat rate shall be calculated as required in Chapter 14 and 40 CFR Part 75. Annual sulfur dioxide emissions for Laramie River Station Unit 3 shall be reported as otherwise provided in Chapter 14, Section 3(b). - (i) Basin Electric Power Cooperative shall report sulfur dioxide emissions as calculated per Section 3(d) as of the year that Basin Electric Power Cooperative commences operation of Selective Catalytic Reduction at Laramie River Station Unit 1 consistent with the notification provision found at WAQSR Chapter 6 Section 2(i)(ii).
(e) The Division of Air Quality shall use the annual sulfur dioxide emissions reported by Basin Electric Power Cooperative in Section 3(d) for all purposes under this Chapter.
