(1) An industrial user subject to categorical pretreatment standards;
(2) An industrial user that:
A. Discharges an average of 25,000 gpd or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blow down wastewater);
B. Contributes a process waste stream which makes up five percent or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or
C. Is designated as such by the City on the basis that it has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement.
(3) The City may determine that an industrial user subject to categorical pretreatment standards is a non-significant categorical industrial user rather than a significant industrial user on a finding that the industrial user never discharges more than 100 gallons per day (gpd) of total categorical wastewater (excluding sanitary, non-contact cooling and boiler blow down wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:
A. The industrial user, prior to City's finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
B. The industrial user annually submits the certification statement required in Section 1043.0697(b) [see 40 CR 403.12(q)], together with any additional information necessary to support the certification statement; and
C. The industrial user never discharges any untreated concentrated wastewater.
D. If the POTW has determined that an IU meets the criteria for non-significant categorical industrial user and is classified as such, the POTW must evaluate and document, at least once per year, whether the industrial user continues to meet the requirements for the classification.
(4) Upon a finding that a user meeting the criteria in paragraph (2) of this definition has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the City may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with procedures in 40 CFR 403.8(f)(6), determine that such user should not be considered a significant industrial user.
(tt) "Slug load or slug discharge." Any discharge at a flow rate or concentration, which could cause a violation of the prohibited discharge standards in Section 1043.021. A slug discharge is any discharge of a non-routine, episodic nature, including but not limited to an accidental spill or a non-customary batch discharge, which has a reasonable potential to cause interference or pass through, or in any other way violate the POTW's regulations, local limits or permit conditions.
