Sec. 420.15  Pretreatment standards for existing sources (PSES).

    Except as provided in 40 CFR 403.7 and 403.13, any existing 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 existing sources (PSES):
    (a) By-product cokemaking.

\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)).

    (1) Increased loadings, not to exceed 13.3 per cent of the above 
limitations, shall be provided for process wastewaters from wet coke 
oven gas desulfurization systems, but only to the extent such systems 
generate process wastewaters.
    (2) 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.
    (3) 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 POTWs.
