An industrial user shall promptly notify the WWTP Superintendent in advance of any substantial change in the volume or character of pollutants in its discharge, or of any facility expansion, production increase, or process modifications that could result in a substantial change in the volume or character of pollutants in its discharge. For purposes of this section,
SUBSTANTIAL CHANGE includes, without limitation, the following: (1) the discharge of any amount of a pollutant not identified in the user's permit application or in the permit issued; (2) an increase in concentration (or degree) of any pollutant that exceeds 15% of the concentration (or degree) for the pollutant as indicated in any report required under §§ 53.091 or 53.092; (3) an increase in discharge volume that exceeds 15% of the volume as indicated in any report required under §§ 53.091 or 53.092; (4) any increase in the amount of any hazardous wastes discharged, including, without limitation, the hazardous wastes for which the industrial user has submitted initial notification under § 53.096 of this chapter; (5) the discharge of any ground waters purged for a removal or remedial action; (6) the discharge of any pollutants that are present in the discharge due to infiltration; or (7) a change in discharge that may convert an industrial user into a significant industrial user. This section shall not be construed to authorize a discharge that exceeds a discharge prohibition or limitation provided by this chapter or a permit. In determining whether to accept any changed discharge, or, if so, under what conditions, the WWTP Superintendent shall evaluate the changed discharge pursuant to the general and specific discharge prohibitions of § 53.050 and other applicable provisions of this chapter.
