NR 409.065(6)(e)1.1. Identification of the unit.

NR 409.065(6)(e)2.2. Certification that the owner or owners or operator operated the affected unit and the NOx emission control system during the demonstration period in accordance with all of the following:

NR 409.065(6)(e)2.a.a. Specifications and procedures designed to achieve the maximum NOx reduction possible with the installed NOx emission control system or the applicable emissions limitation in sub. (2), (3) or (4).

NR 409.065(6)(e)3.3. Certification that the owner or owners or operator have installed in the affected unit all NOx emission control systems, made any operational modifications, and completed any planned upgrades and maintenance to equipment specified in the approved demonstration period plan for optimizing NOx emission reduction performance, consistent with the demonstration period plan and the proper operation of the installed NOx emission control system. The certification shall explain any differences between the installed NOx emission control system and the equipment configuration described in the approved demonstration period plan.

NR 409.065(6)(e)4.4. A clear description of each step or modification taken during the demonstration period to improve or optimize the performance of the installed NOx emission control system.

NR 409.065(6)(e)5.5. Engineering design calculations and drawings that show the technical specifications for installation of any additional operational or emission control modifications installed during the demonstration period.

NR 409.065(6)(e)6.6. Unit operating and quality-assured continuous emission monitoring data, including the specific data listed in sub. (9) (e), collected in accordance with 40 CFR part 75 during the demonstration period and demonstrating the inability of the specific unit to meet the applicable emission limitation in sub. (2), (3) or (4) on an annual average basis while operating in accordance with the certification under subd. 2.

NR 409.065(6)(e)7.7. A report, based on the parametric test requirements in the approved demonstration period plan as identified in par. (d) 13., that demonstrates the unit was operated in accordance with the operating conditions upon which the design of the NOx emission control system was based and describes the reason or reasons for the failure of the installed NOx emission control system to meet the applicable emission limitation in sub. (2), (3) or (4) on an annual-average basis.

NR 409.065(6)(e)8.8. The minimum NOx emission rate, in pounds per million Btu, that the affected unit can achieve on an annual average basis with the installed NOx emission control system. This value, which shall be the requested alternative emission limitation, shall be derived from the data specified in this section using methods and procedures satisfactory to U.S. EPA and shall be the lowest annual emission rate the unit can achieve with the installed NOx emission control system.

NR 409.065(6)(e)9.9. All supporting data and calculations documenting the determination of the requested alternative emission limitation and its conformance with the methods and procedures satisfactory to U.S. EPA.

NR 409.065(6)(e)10.10. The special provisions in par. (g) 2.

NR 409.065(6)(e)11.11. In addition to the other requirements of this section, the owner or operator of an affected unit with a Group 1 boiler that has installed an alternative technology, in addition to or in lieu of low NOx burner technology, and cannot meet the applicable emission limitation in sub. (2) shall demonstrate, to the satisfaction of U.S. EPA, that the actual percentage reduction in NOx emissions (pounds per million Btu), on an annual average basis is greater than 65% of the average annual NOx emissions prior to the installation of the NOx emission control system. The percentage reduction in NOx emissions shall be determined using continuous emissions monitoring data for NOx taken during the time period, under par. (d) 3., prior to the installation of the NOx emission control system and during long-term load dispatch operation of the specific boiler.
