Chapter NR 433

NR 433.05(1) (1) Preliminary determination.

NR 433.05(1)(a) (a) The department shall make a preliminary determination of the BART requirements for each emissions unit which comprises the sources subject to BART based on the information in the BART analysis required under s. NR 433.04 and other available information. The preliminary BART determination for each facility shall include all of the following elements:

NR 433.05(1)(a)1. 1. A list of all emissions units which comprise the source subject to BART.

NR 433.05(1)(a)2. 2. A determination of the BART requirements for each emissions unit.

NR 433.05(1)(a)3. 3. Requirements for initial performance tests and for demonstrating compliance with the emission limits representing BART on a continuous basis, including emission monitoring, recordkeeping and reporting.

NR 433.05(1)(a)4. 4. The requirement that the owner or operator of each source subject to BART shall install and operate BART as expeditiously as practicable, but in no event later than December 31, 2015.

NR 433.05(1)(a)5. 5. The requirement that the owner or operator of each source subject to BART shall maintain the control equipment required by the BART determination and establish procedures to ensure the equipment is properly operated and maintained.

NR 433.05(1)(b) (b) The determination of BART shall be based on the department’s review of the analysis of the best system of continuous emission control technology available and associated emission reductions achievable for each unit subject to BART at the facility. The department shall take into consideration the technology available, the costs of compliance, the energy and non-air quality environmental impacts of compliance, any pollution control equipment in use at the source, the remaining useful life of the source, and the degree of improvement in visibility which may reasonably be anticipated to result from use of the technology.

NR 433.05(1)(c) (c) The determination of BART for all emissions units which comprise the source subject to BART shall be made pursuant to the applicable guidelines in 40 CFR part 51, Appendix Y, incorporated by reference in s. NR 484.04 (11m).

NR 433.05(1)(d) (d) If the department determines that it is technologically or economically infeasible for a source to install and operate the available control technologies, it may instead prescribe a design, equipment, work practice, or other operational standard, or combination thereof to meet the BART requirements. The department shall estimate the emission reduction to be achieved by implementation of the design, equipment, work practice or operation, and shall prescribe the method for demonstrating compliance.

NR 433.05(1)(e) (e) If a fossil-fuel fired steam electric plant is subject to the clean air interstate rule trading programs under 40 CFR part 97 the determination of BART shall be made for particulate matter emissions only.

NR 433.05(1)(f) (f) The department shall incorporate the results of its preliminary BART determination in a draft revision to the source’s air quality permit.

NR 433.05(2) (2) Exception. The department may not make a determination of BART for SO2 or for NOX if the potential to emit of a BART-eligible source is less than 40 tons per year of the respective pollutant; or for particulate matter, if the potential to emit PM10 of a BART-eligible source is less than 15 tons per year.

NR 433.05(3) (3) Public notice and comment. The department shall notify the owner or operator of the source subject to BART and the EPA of its preliminary BART determination and shall publish a notice of its preliminary BART determination and the draft permit conditions for public comment. The department shall provide at least 30 days for submittal of written comments.

NR 433.05(4) (4) Final determination. Following the close of the public comment period and after consideration of all public comments, the department shall make a final BART determination and issue a revision to the facility’s air quality permit which includes the BART requirements.

NR 433.05(5) (5) Revision. The department may revise the BART requirements in the air quality permit, if the EPA requires a revision of the BART requirements or the department determines that the revision of the existing BART requirements is justified based on safety, health, environmental or excessive cost impacts which the original BART analysis and BART determination failed to take into account. The department shall provide notice and offer an opportunity for public comment on any proposed revision under this section.

NR 433.06 NR 433.06 Emissions trading program for boilers.

NR 433.06(1) (1) The owner or operator of a facility, having at least one boiler subject to BART, may propose an emissions trading program if the program achieves an improvement in visibility in the mandatory class I federal areas greater than would be achieved through the installation and operation of BART on each boiler subject to BART. The owner or operator of a boiler subject to BART who is proposing to use an emissions trading program shall submit an emissions trading plan to the department. The plan shall be subject to department approval and meet the following criteria:

NR 433.06(1)(a) (a) The plan shall contain the proposed control strategy and the method of demonstrating compliance.

NR 433.06(1)(b) (b) The plan shall achieve either of the following:

NR 433.06(1)(b)1. 1. For each visibility impairing pollutant for which compliance is demonstrated through use of a trading plan, an emission reduction of that pollutant at least 10% greater than would be achieved through the installation and operation of BART on each boiler subject to BART.

NR 433.06(1)(b)2. 2. An improvement in visibility in the mandatory class I federal areas greater than or equal to the visibility improvement achieved under subd. 1. The improvement in visibility shall be demonstrated by comparing the 20% best days of visibility and the 20% worst days of visibility in at least the 4 mandatory class I federal areas nearest to the source and for each calendar year 2002, 2003 and 2004. The daily visibility shall be determined using an air quality model approved by the EPA for predicting visibility impacts from single emission sources and conducting the air quality modeling analyses according to the guidelines in 40 CFR part 51, Appendix Y, incorporated by reference in s. NR 484.04 (11m).

NR 433.06(1)(c) (c) Trading shall be between all boilers serving a similar function and located on the same property.

NR 433.06(1)(d) (d) Boilers participating in the trading shall achieve the required emission reductions on a continuous basis and shall be subject to continuous emission monitoring, which meets the applicable requirements under ch. NR 439 or 440.

NR 433.06(1)(e) (e) The plan shall specify the monitoring devices and procedures which will be used to provide information sufficient to assess the performance of the proposed emission control measures and to quantify on an hourly average basis the mass flow of each pollutant in pounds per hour and the emission rate of each pollutant in pounds per mmBtu heat input for each boiler participating in the trading. The procedures and methods required for compliance demonstration and for performance testing shall be according to the applicable requirements of ch. NR 439 or 440.

NR 433.06(1)(f) (f) Excess emission reductions, for the purposes of meeting the BART requirements, shall be emission reductions beyond those required to meet all state and federal requirements and may not include emission reductions used in any other banking or trading program.

NR 433.06(2) (2) If the department approves the emissions trading plan, the department shall propose to revise the source’s air quality permit to include the requirements of the emissions trading plan in lieu of the BART requirements for the boilers identified in the emissions trading plan.

NR 433.06(3) (3) After the department incorporates the emissions trading plan in the revised air operation permit, the owner or operator of the BART-eligible source shall comply with the requirements of the emissions trading plan for the boilers identified in the plan.
