Sec.  420.16  Pretreatment standards for new sources (PSNS).



    Except as provided in 40 CFR 403.7, any new source subject to this 

subpart that introduces pollutants into a publicly owned treatment works 

must comply with 40 CFR part 403 and must achieve the following 

pretreatment standards for new sources (PSNS), 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.  420.16 of title 40 of the Code of Federal 

Regulations, revised as of July 1, 2001, (except for the standards for

facility, whichever comes first, after which the source must achieve the 

standards specified in Sec.  420.15(a).

    (A) Increased loadings, not to exceed 13.3 percent 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. Except as provided in 40 CFR 403.7,
