“Significant industrial user” (or SIU), as defined and set forth in 40 CFR 403.3(v), except as provided in subsections (3) and (4) of this definition, means:
1. All industrial users subject to categorical pretreatment standards under 40 CFR 403.6 and 40 CFR Chapter I, Subchapter N; and
2. Any other industrial user that:
a. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown 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 control authority on the basis that the industrial user has a reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standard or requirement (in accordance with 40 CFR 403.8(f)(6)).
3. The control authority may determine that an industrial user subject to categorical pretreatment standards under 40 CFR 403.6 and 40 CFR Chapter I, Subchapter N is a nonsignificant 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, noncontact cooling and boiler blowdown wastewater, unless specifically included in the pretreatment standard) and the following conditions are met:
a. The industrial user, prior to the control authority’s finding, has consistently complied with all applicable categorical pretreatment standards and requirements;
b. The industrial user annually submits the certification statement required in 40 CFR 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.
4. Upon a finding that an industrial user meeting the criteria in subsection (2)(b) of this definition has no reasonable potential for adversely affecting the POTW’s operation or for violating any pretreatment standards or requirement, the control authority may at any time, on its own initiative or in response to a petition received from an industrial user or POTW, and in accordance with 40 CFR 403.8(f)(6), determine that such industrial user is not a significant industrial user.
“Significant noncompliance,” as defined and set forth in 40 CFR 403.8(f)(2)(viii), means a significant industrial user (or any industrial user which violates subsection (3), (4) or (8) of this definition) is in significant noncompliance if its violation meets one or more of the following criteria:
1. Chronic violations of wastewater discharge limits, defined here as those in which 66 percent or more of all of the measurements taken for the same pollutant parameter during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(l);
2. Technical review criteria (TRC) violations, defined here as those in which 33 percent or more of all of the measurements taken for the same pollutant parameter during a six-month period equal or exceed the product of the numeric pretreatment standard or requirement including instantaneous limits, as defined by 40 CFR 403.3(l) multiplied by the applicable TRC (TRC=1.4 for BOD, TSS, fats, oil, and grease, and 1.2 for all other pollutants except pH);
3. Any other violation of a pretreatment standard or requirement as defined by 40 CFR 403.3(l) (daily maximum, long-term average, instantaneous limit, or narrative standard) that the POTW determines has caused, alone or in combination with other discharges, interference or pass-through (including endangering the health of POTW personnel or the general public);
4. Any discharge of a pollutant that has caused imminent endangerment to human health, welfare or to the environment or has resulted in the POTW’s exercise of its emergency authority under 40 CFR 403.8(f)(1)(vi)(B) to halt or prevent such a discharge;
5. Failure to meet, within 90 days after the schedule date, a compliance schedule milestone contained in a local control mechanism or enforcement order for starting construction, completing construction, or attaining final compliance;
6. Failure to provide, within 30 days after the due date, required reports such as baseline monitoring reports, 90-day compliance reports, periodic self-monitoring reports, and reports on compliance with compliance schedules;
7. Failure to accurately report noncompliance;
8. Any other violation or group of violations, which may include a violation of best management practices, which the POTW determines will adversely affect the operation or implementation of the local pretreatment program.
“Single-family user” means all users living in a dwelling unit that is occupied by one family or by not more than five unrelated persons. It includes detached single-family residences, and zero-lot-line buildings wherein the building is on a separate fee simple lot and used for residential purposes.
“Slug discharge” means any discharge of a nonroutine, episodic nature, including but not limited to an accidental spill or a noncustomary batch discharge, which has a reasonable potential to cause interference or pass-through, or in any other way violate the POTW’s ordinances, local laws or permit conditions. POTWs are required to ensure that industrial users have policies and procedures in place to prevent or mitigate the effects of slug discharges.
“Slug discharge control plan” as defined and set forth in 40 CFR 403.8(f)(2)(vi), means a plan by which significant industrial users control slug discharges.
“Spill” means any nonintentional discharge which enters the POTW.
“Standard industrial classification” (or “SIC”) means a classification pursuant to the most recent edition of the “Standard Industrial Classification Manual,” issued by the Executive Office of the President, Office of Management and Budget.
“State” means the state of Washington.
“Storm sewer” means a pipe system or conduit which carries storm and surface waters and drainage, but excludes sewage and industrial wastes, other than unpolluted cooling water. (Ord. 3220 § 1, 2016; Ord. 3025 § 2, 2013; Ord. 2742 § 1, 2008; Ord. 2070 § 3, 1996; Ord. 1831 §§ 3, 4 & 5, 1991; Ord. 1706, 1989)
