Section 1302-122-F-122.66 - Permits for boilers and industrial furnaces burning hazardous waste

When an owner or operator of a cement or lightweight aggregate kiln demonstrates compliance with the air emission standards and limitations in 40 CFR Part 63, Subpart EEE (i.e., by conducting a comprehensive performance test and submitting a Notification of Compliance), the requirements of this section do not apply.

Nevertheless, the Director may apply the provisions of this section, on a case-by-case basis, for purposes of information collection in accordance with Sections 122.10(k) and 122.32(b)(2).

(a) General. Owners and operators of new boilers and industrial furnaces (those not operating under the interim status standards of Section 266.103 of these regulations) are subject to paragraphs (b) through (f) of this section. Boilers and industrial furnaces operating under the interim status standards of Section 266.103 of these regulations are subject to paragraph (g) of this section.

(b) Permit operating periods for new boilers and industrial furnaces. A permit for a new boiler or industrial furnace shall specify appropriate conditions for the following operating periods:

(1) Pretrial burn period. For the period beginning with initial introduction of hazardous waste and ending with initiation of the trial burn, and only for the minimum time required to bring the boiler or industrial furnace to a point of operational readiness to conduct a trial burn, not to exceed 720 hours operating time when burning hazardous waste, the Secretary must establish in the Pretrial Burn Period of the permit conditions, including but not limited to, allowable hazardous waste feed rates and operating conditions. The Secretary may extend the duration of this operational period once, for up to 720 additional hours, at the request of the applicant when good cause is shown. The permit may be modified to reflect the extension according to Section 122.42.

(i) Applicants must submit a statement, with Part B of the permit application, that suggests the conditions necessary to operate in compliance with the standards of Sections 266.104 through 266.107 of these regulations during this period. This statement should include, at a minimum, restrictions on the applicable operating requirements identified in Section 266.102(e) of these regulations.

(ii) The Secretary will review this statement and any other relevant information submitted with Part B of the permit application and specify requirements for this period sufficient to meet the performance standards of Sections 266.104 through 266.107 of these regulations based on his/her engineering judgment.

(2) Trial burn period. For the duration of the trial burn, the Secretary must establish conditions in the permit for the purposes of determining feasibility of compliance with the performance standards of Sections 266.104 through 266.107 of these regulations and determining adequate operating conditions under Section 266.102(e) of these regulations. Applicants must propose a trial burn plan, prepared under paragraph (c) of this section, to be submitted with Part B of the permit application.

(3) Post-trial burn period.

(i) 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 permit by the Secretary to reflect the trial burn results, the Secretary will establish the operating requirements most likely to ensure compliance with the performance standards of Sections 266.104 through 266.107 of these regulations based on his engineering judgment.

(ii) Applicants must submit a statement, with Part B of the application, that identifies the conditions necessary to operate during this period in compliance with the performance standards of Sections 266.104 through 266.107 of these regulations. This statement should include, at a minimum, restrictions on the operating requirements provided by Section 266.102(e) of these regulations.

(iii) The Secretary will review this statement and any other relevant information submitted with Part B of the permit application and specify requirements for this period sufficient to meet the performance standards of Sections 266.104 through 266.107 of these regulations based on his/her engineering judgment.

(4) Final permit period. For the final period of operation, the Secretary will develop operating requirements in conformance with Section 266.102(e) of these regulations that reflect conditions in the trial burn plan and are likely to ensure compliance with the performance standards of Sections 266.104 through 266.107 of these regulations. Based on the trial burn results, the Secretary shall make any necessary modifications to the operating requirements to ensure compliance with the performance standards. The permit modification shall proceed according to Section 122.42.

(c) Requirements for trial burn plans. The trial burn plan must include the following information. The Secretary, in reviewing the trial burn plan, shall evaluate the sufficiency of the information provided and may require the applicant to supplement this information, if necessary, to achieve the purposes of this paragraph:

(1) An analysis of each feed stream, including hazardous waste, other fuels, and industrial furnace feed stocks, as fired, that includes:

(i) Heating value, levels of antimony, arsenic, barium, beryllium, cadmium, chromium, lead, mercury, silver, thallium, total chlorine/chloride, and ash;
