    (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.
