Where a treated regulated process wastestream is combined prior to treatment with wastewaters other than those generated by the regulated process, the industrial user may monitor either the segregated process wastestream or the combined wastestreams for the purpose of determining compliance with applicable pretreatment standards. If the industrial user chooses to monitor the segregated process wastestream, it shall apply the applicable categorical pretreatment standard. If the user chooses to monitor the combined wastestream, it shall apply an alternative discharge limit calculated using the combined wastestream formula as provided by federal regulations. The industrial user may change monitoring points only after receiving approval from the Authority. The Authority shall ensure that any change in an industrial user’s monitoring point(s) will not allow the user to substitute dilution for adequate treatment to achieve compliance with applicable standards.
