    (1) 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.
    (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 waters of the U.S.
