This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature. It also includes lift stations, sewers, pipes and other conveyances only if they convey wastewater to a POTW treatment plant.
means a weight to weight ratio; the parts per million value multiplied by the factor 8.345 shall be equivalent to pounds per million gallons of water.
means the reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater to a less harmful state prior to or in lieu of discharging or otherwise introducing such pollutants into the POTW.

Upon finding that an industrial user meeting the criteria in subsection (1)b. has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirements, the environmental officer may at any time, on his own initiative or in response to a petition received from an industrial user, and in accordance with 40 CFR 403.8(f)(6), determine that such industrial user is not a significant industrial user.
means any discharge of a nonroutine, episodic nature, including but not limited to an accidental spill or a noncustomary batch discharge, and/or a discharge which violates any prohibited discharge standard in section 94-20, and/or could significantly disrupt the POTW and/or threaten human health and safety, and/or could potentially result in violations of the POTW's NPDES permit or sludge requirements.
