Sec.  420.14  New source performance standards (NSPS).



    New sources subject to this subpart must achieve the following new 

source performance standards (NSPS), as applicable.

    (a) By-product cokemaking. (1) Any new source subject to the 

provisions of this section that commenced discharging after November 18, 

1992, and before November 18, 2002, must continue to achieve the 

standards specified in Sec.  420.14 of title 40 of the Code of Federal 

Regulations, revised as of July 1, 2001, except as provided below. For 

toxic and nonconventional pollutants, those standards shall apply until 

the expiration of the applicable time period specified in 40 CFR 

122.29(d)(1); thereafter, the source must achieve the effluent 

limitations specified in Sec.  420.13(a).

    (2) The following standards apply with respect to each new source 

that commences construction after November 18, 2002:

    (A) Increased loadings, not to exceed 13.3 per cent of the above 

limitations, shall be provided for process wastewaters from coke oven 

gas wet desulfurization systems, but only to the extent such systems 

generate process wastewaters.

    (B) Increased loadings shall be provided for process wastewaters 

from other wet air pollution control systems (except those from coal 

charging and coke pushing emission controls), coal tar processing 

operations and coke plant groundwater remediation systems, but only to 

the extent such systems generate process wastewaters and those 

wastewaters are co-treated with process wastewaters from by-product 

cokemaking wastewaters.

    (C) Increased loadings, not to exceed 44.2 percent of the above 

limitations, shall be provided for water used for the optimization of 

coke plant biological treatment systems.

    (b) Cokemaking--non-recovery. There shall be no discharge of process 

wastewater pollutants to waters of the U.S.
