§63.300. Applicability. — Inbound Citations

(1) Approval of alternatives to the requirements in §§ 63.300 and 63.302 through 63.308 (except the authorities in 63.306(a)(2) and (d)).

(b) The enforcement agency shall commence daily performance tests on the applicable date specified in § 63.300 (a) or (c).

(k) The owner or operator of a new nonrecovery coke oven battery shall conduct a performance test to demonstrate initial compliance with the emission limitations for a charging emissions control device in § 63.303(d)(2) within 180 days of the compliance date that is specified for the affected source in § 63.300(a)(4) and report the results in the notification of compliance status. The owner or operator shall prepare a site-specific test plan according to the requirements in § 63.7(c) and shall conduct each performance test according to the requirements in paragraphs (a) and (k)(1) through (4) of this section.

(1) Determine the concentration of PM according to the following test methods in appendices A-1 through A-3 to 40 CFR part 60

(i) Sampling sites must be located at the outlet of the control device and prior to any releases to the atmosphere.

(iii) You may also use as an alternative to Method 3B, the manual method (but not instrumental procedures) for measuring the oxygen, carbon dioxide, and carbon monoxide content of exhaust gas, ANSI/ASME PTC 19.10-1981 (incorporated by reference, see § 63.14).

(2) During each PM test run, sample only during periods of actual charging when the capture system fan and control device are engaged. Collect a minimum sample volume of 30 dry standard cubic feet (dscf) during each test run. Three valid test runs are needed to comprise a performance test. Each run must start at the beginning of a charge and finish at the end of a charge (i.e., sample for an integral number of charges).

(3) Determine and record the total combined weight of tons of dry coal charged during the duration of each test run.

(4) Compute the process-weighted mass emissions (Ep) for each test run using Equation 1 of this section as follows:

(b) Except as provided in paragraph (c) of this section, no owner or operator shall cause to be discharged or allow to be discharged to the atmosphere, coke oven emissions from a by-product coke oven battery subject to the applicability requirements in § 63.300(b) that exceed any of the following emission limitations:

(1) 0.0 percent leaking coke oven doors, as determined by the procedures in § 63.309(d)(1);

(2) 0.0 percent leaking topside port lids, as determined by the procedures in § 63.309(d)(1);

(3) 0.0 percent leaking offtake system(s), as determined by the procedures in § 63.309(d)(1); and

(4) 34 seconds of visible emissions per charge, as determined by the procedures in § 63.309(d)(2).

(b) No owner or operator shall cause to be discharged or allow to be discharged to the atmosphere coke oven emissions from each affected new nonrecovery coke oven battery subject to the applicability requirements in § 63.300(b) that exceed any of the following emission limitations or requirements:

(1) For coke oven doors and common tunnels;

(i) 0.0 percent leaking coke oven doors, as determined by the procedures in § 63.309(d)(1); and

(ii) The owner or operator shall monitor and record, once per day for each day of operation, the pressure in each oven or in each common battery tunnel during pushing, charging, and coking to ensure that the ovens are operated under a negative pressure.

(iii) The date for compliance with paragraphs (b)(1)(i) and (ii) of this section is on and after July 7, 2025, or upon initial startup, whichever is later.

(2) For charging operations, the owner or operator shall install, operate, and maintain an emission control system for the capture and collection of emissions in a manner consistent with good air pollution control practices for minimizing emissions from the charging operation;

(3) For charging operations, the owner or operator shall implement, for each day of operation, the work practices specified in § 63.306(b)(6) and record the performance of the work practices as required in § 63.306(b)(7).

(4) 0.0 percent leaking topside port lids, as determined by the procedures in § 63.309(d)(1) (if applicable to the new nonrecovery coke oven battery); and

(5) 0.0 percent leaking offtake system(s), as determined by the procedures in § 63.309(d)(1) (if applicable to the new nonrecovery coke oven battery).

(b) The enforcement agency shall commence daily performance tests on the applicable date specified in § 63.300 (a) or (c).

Terms used in this subpart are defined in the Act or in this section as follows:

(i) The owner or operator shall install, operate, and maintain a continuous opacity monitor, and record the output of the system, for the measurement of the opacity of emissions discharged from the emission control system per §§ 63.300(e) and 63.8(d)(1) and (2).

(A) Each continuous opacity monitoring system shall meet the requirements of Performance Specification 1 in appendix B to 40 CFR part 60; and

(B) Each continuous opacity monitoring system shall be operated, calibrated, and maintained according to the procedures and requirements specified in 40 CFR part 52; and

(C) The owner or operator shall keep the written procedures required by § 63.8(d)(1) and (2) on record for the life of the affected source or until the affected source is no longer subject to the provisions of this part, to be made available for inspection, upon request, by the Administrator. If the performance evaluation plan is revised, the owner or operator shall keep previous (i.e., superseded) versions of the performance evaluation plan on record to be made available for inspection, upon request, by the Administrator, for a period of 5 years after each revision to the plan. The program of corrective action should be included in the plan required under § 63.8(d)(2); or

(iii) The cause of the leak (including unknown cause, if applicable), any actions taken to minimize emissions in accordance with and § 63.300(e), the corrective action taken to stop the leak.
