NR 664.0343(4)(4) For purposes of license enforcement, compliance with the operating requirements specified in the license (under s. NR 664.0345) is compliance with this section. However, evidence that compliance with those license conditions is insufficient to ensure compliance with the performance requirements of this section may be “information” justifying modification, revocation or reissuance of a license under s. NR 670.041.

NR 664.0343 HistoryHistory: CR 05-032: cr. Register July 2006 No. 607, eff. 8-1-06; CR 16-007: am. (1) (b) Register July 2017 No. 739, eff. 8-1-17.

NR 664.0344(1)(1) The owner or operator of a hazardous waste incinerator may burn only wastes specified in the owner or operator’s license and only under operating conditions specified for those wastes under s. NR 664.0345, except in any of the following circumstances:

NR 664.0344(1)(a)(a) In approved trial burns under s. NR 670.062.

NR 664.0344(1)(b)(b) Under exemptions created by s. NR 664.0340.

NR 664.0344(2)(2) Other hazardous wastes may be burned only after the department has specified operating conditions in a new license or a license modification as applicable. The department may base operating requirements for new wastes on either trial burn results or alternative data included with the feasibility and plan of operation report under s. NR 670.019.

NR 664.0344(3)(3) The license for a new hazardous waste incinerator shall establish appropriate conditions for each of the applicable requirements of this subchapter, including but not limited to allowable waste feeds and operating conditions necessary to meet s. NR 664.0345, sufficient to comply with all of the following standards:

NR 664.0344(3)(a)(a) For the period beginning with initial introduction of hazardous waste to the incinerator and ending with initiation of the trial burn, and only for the minimum time required to establish operating conditions required in par. (b), not to exceed a duration of 720 hours operating time for treatment of hazardous waste, the operating requirements shall be those most likely to ensure compliance with the performance standards of s. NR 664.0343, based on the department’s engineering judgment. The department may extend the duration of this period once for up to 720 additional hours when the applicant demonstrates good cause for the extension.

NR 664.0344(3)(b)(b) For the duration of the trial burn, the operating requirements shall be sufficient to demonstrate compliance with the performance standards of s. NR 664.0343 and shall be according to the approved trial burn plan.

NR 664.0344(3)(c)(c) For the period immediately following completion of the trial burn, and only for the minimum period sufficient to allow sample analysis, data computation and submission of the trial burn results by the applicant, and review of the trial burn results and modification of the facility license by the department, the operating requirements shall be those most likely to ensure compliance with the performance standards of s. NR 664.0343, based on the department’s engineering judgment.

NR 664.0344(3)(d)(d) For the remaining duration of the license, the operating requirements shall be those demonstrated, in a trial burn or by alternative data specified in s. NR 670.019 (3), as sufficient to ensure compliance with the performance standards of s. NR 664.0343.

NR 664.0345(1)(1) The owner or operator shall operate an incinerator according to the operating requirements in the license. The department will specify these on a case-by-case basis as those demonstrated (in a trial burn or in alternative data as specified in s. NR 664.0344 (2) and included with the feasibility and plan of operation report) to be sufficient to comply with the performance standards of s. NR 664.0343.

NR 664.0345(2)(2) Each set of operating requirements will specify the composition of the waste feed (including acceptable variations in the physical or chemical properties of the waste feed which will not affect compliance with the performance requirement of s. NR 664.0343) to which the operating requirements apply. For each waste feed to which the operating requirements apply, the license will specify acceptable operating limits including all of the following conditions:

NR 664.0345(2)(a)(a) Carbon monoxide (CO) level in the stack exhaust gas.

NR 664.0345(2)(b)(b) Waste feed rate.

NR 664.0345(2)(c)(c) Combustion temperature.

NR 664.0345(2)(d)(d) An appropriate indicator of combustion gas velocity.

NR 664.0345(2)(e)(e) Allowable variations in incinerator system design or operating procedures.

NR 664.0345(2)(f)(f) Other operating requirements as are necessary to ensure that the performance standards of s. NR 664.0343 are met.

NR 664.0345(3)(3) During start-up and shut-down of an incinerator, the owner or operator shall not feed hazardous waste (except wastes exempted according to s. NR 664.0340) into the incinerator unless the incinerator is operating within the conditions of operation (temperature, air feed rate, etc.) specified in the license.

NR 664.0345(4)(a)(a) Keeping the combustion zone totally sealed against fugitive emissions.

NR 664.0345(4)(b)(b) Maintaining a combustion zone pressure lower than atmospheric pressure.

NR 664.0345(4)(c)(c) An alternate means of control demonstrated (with the feasibility and plan of operation report) to provide fugitive emissions control equivalent to maintenance of combustion zone pressure lower than atmospheric pressure.

NR 664.0345(5)(5) The owner or operator shall operate an incinerator with a functioning system to automatically cut off waste feed to the incinerator when operating conditions deviate from limits established under sub. (1).

NR 664.0345(6)(6) The owner or operator shall cease operation of an incinerator when changes in waste feed, incinerator design or operating conditions exceed limits designated in its license.
