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 19, 
2012 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 
phenols 4AAP) for ten years beginning on the date the source commenced 
discharge or during the period of depreciation or amortization of the 
facility, whichever comes first, after which the source must achieve the 
standards specified in Sec. 420.15(a).
    (2) Except as provided in 40 CFR 403.7, the following standards 
apply with respect to each new source that commences construction after 
November 18, 2002:

\1\ Pounds per thousand lb of product.
\2\ The pretreatment standards for ammonia are not applicable to sources
  that discharge to a POTW with nitrification capability (defined at
  Sec. 420.02(s)).

    (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, the following standards apply with respect to each new source 
that commences construction after November 18, 2002: There shall be no 
discharge of process wastewater pollutants to POTWs.
