Unless expressly authorized to do so by an applicable pretreatment standard or requirement and subject to the prior approval of the POTW Manager, no user shall ever increase the use of process water, mix separate wastestreams, or in any other way attempt to dilute a discharge as a partial or complete substitute for adequate treatment to achieve compliance with a federal, state or local standard, requirement or limitation. The POTW may impose mass limitations on nondomestic users that are using dilution to meet applicable pretreatment standards or requirements and in other cases where the imposition of mass limitations is appropriate. Combining a user’s wastestream or modulating the release of pollutants upstream of the sampling point prior to the point of discharge into the public sewer shall not be construed as dilution, except as otherwise restricted by National Categorical Pretreatment Standards or requirements. No user intending to use dilution as a substitute for treatment shall do so without the prior approval of the POTW Manager consistent with the requirements of this section.
