\1\ Pounds per thousand pound of product.
\2\ The pretreatment standards for these parameters apply only when sintering wastewater is co-treated with
  ironmaking wastewater.
\3\The pretreatment standards for ammonia are not applicable to sources that discharge to a POTW with
  nitrification capability (defined at Sec. 420.02(s)).

    (b) Sintering operations with dry air pollution control system. 
There shall be no discharge of process wastewater pollutants to POTWs.
