NR 440.205(5)(f)(f) Any owner or operator of an affected facility that combusts byproduct/waste with either natural gas or oil may petition the administrator within 180 days of the initial startup of the affected facility to establish a nitrogen oxide emission limit which shall apply specifically to that affected facility when the byproduct/waste is combusted. The petition shall include sufficient and appropriate data, as determined by the administrator, such as nitrogen oxides emissions from the affected facility, waste composition (including nitrogen content), and combustion conditions to allow the administrator to confirm that the affected facility is unable to comply with the emission limits in par.

Any owner or operator of an affected facility petitioning for a facility-specific nitrogen oxides emission limit under this subsection shall: NR 440.205(5)(f)1.a.a. Demonstrate compliance with the emission limits in the par. (a) table for natural gas and distillate oil or for residual oil as appropriate, by conducting a 30-day performance test as provided in sub. (7) (e). During the performance test only natural gas, distillate oil, or residual oil shall be combusted in the affected facility; and NR 440.205(5)(f)1.b.b. Demonstrate that the affected facility is unable to comply with the emission limits in the par.

(a) table for natural gas or distillate oil or for residual oil, as appropriate, shall be applicable to the affected facility until and unless the petition is approved by the administrator. If the petition is approved by the administrator, a facility-specific nitrogen oxides emission limit will be established at the nitrogen oxides emission level achievable when the affected facility is combusting oil or natural gas and byproduct/waste in a manner which the administrator determines to be consistent with minimizing nitrogen oxides emissions.

The petition shall include sufficient and appropriate data, as determined by the administrator, on nitrogen oxides emissions from the affected facility, waste destruction efficiencies, waste composition (including nitrogen content), the quantity of specific wastes to be combusted and combustion conditions, to allow the administrator to determine if the affected facility is able to comply with the nitrogen oxides emission limits required by this subsection. The owner or operator of the affected facility shall demonstrate that when hazardous waste is combusted in the affected facility, thermal destruction efficiency requirements for hazardous waste specified in an applicable federally enforceable requirement preclude compliance with the nitrogen oxides emission limits of this subsection. The nitrogen oxides emission limits in the par. (a) table for natural gas or distillate oil or for residual oil, as appropriate, are applicable to the affected facility until and unless the petition is approved by the administrator.

NR 440.08, whichever date comes first, no owner or operator of an affected facility which commenced construction, modification or reconstruction after July 9, 1997 may cause to be discharged into the atmosphere from that affected facility any gases that contain nitrogen oxides (expressed as NO2) in excess of one of the following limits: NR 440.205(5)(L)1.1. If the affected facility combusts coal, oil or natural gas, or a mixture of these fuels, or with any other fuels: a limit of 86 ng/J (0.20 lb/million Btu) heat input unless the affected facility has an annual capacity factor for coal, oil and natural gas of 10% (0.10) or less and is subject to a federally enforceable requirement that limits operation of the facility to an annual capacity factor of 10% (0.10) or less for coal, oil and natural gas. NR 440.205(5)(L)2.2. If the affected facility has a low heat release rate and combusts natural gas or distillate oil in excess of 30% of the heat input from the combustion of all fuels, a limit determined by use of the following formula: En = [(0.10 * Hgo) + (0.20 * Hr)]/(Hgo + Hr)
