The Pennsylvania Code website reflects the Pennsylvania Code changes effective through 54 Pa.B. 488 (January 27, 2024).

25 Pa. Code § 123.23. Byproduct coke oven gas.

§ 123.23. Byproduct coke oven gas.

 (a)  No person may permit the emission of byproduct coke oven gas into the outdoor atmosphere unless the gas is first burned.

 (b)  No person may permit the flaring or combustion of a coke oven byproduct gas which contains sulfur compounds, expressed as equivalent hydrogen sulfide, in concentrations greater than 50 grains per 100 dry standard cubic feet. The sulfur compounds, expressed as equivalent hydrogen sulfide, emitted into the outdoor atmosphere from any tail gas sulfur recovery equipment utilized in a coke oven gas desulfurization system approved by the Department shall be included in the determination of these concentrations.

 (c)  Subsections (a) and (b) do not apply to emissions of coke oven gas from:

   (1)  An oven which is dampered off:

     (i)   Prior to and during the pushing operation of the oven.

     (ii)   Because of some malfunction associated with the oven.

   (2)  Unavoidable oven leakage occurring during the coking cycle.

 (d)  Sections 129.12 and 129.13 (relating to sulfuric acid plants; and sulfur recovery plants) may not be applicable to processes operated in conjunction with the desulfurization of byproduct coke oven gas, provided that the standards in this section have been complied with.


   The provisions of this §  123.23 adopted September 10, 1971, effective September 11, 1971, 1 Pa.B. 1804; amended March 3, 1972, effective March 20, 1972, 2 Pa.B. 383; amended October 25, 1974, effective November 11, 1974, 4 Pa.B. 2283; amended April 27, 1979, effective August 1, 1979, 9 Pa.B. 1534.

Notes of Decisions

   There is no violation of procedural due process where an order to make certain changes in coke oven operations does not place new or increased legal duties on the operator but only redefines and mitigates what had been an immediate, current legal duty under the regulations and a compliance schedule is specified and no variance request is made.
