MAXIMUM ALLOWABLE INDUSTRIAL LOADING (MAIL): The estimated maximum loading of a pollutant that can be received at the POTW headworks from all permitted industrial users and other controlled sources without causing pass-through or interference.
MINOR INDUSTRIAL USER (MIU): A nonresidential user with an indirect discharge to the POTW that does not meet the criteria as a significant industrial user or a significant connecting user, but whose operation and discharge may warrant inspection to ensure compliance with discharge prohibitions, pretreatment facility operation, spill prevention measures and pollution prevention assistance.
NPDES: National pollutant discharge elimination system permit program as administered by the USA EPA or state.
NEW SOURCE:
   A.   Any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under section 307(c) of the act, which will be applicable to such source if such standards are thereafter promulgated in accordance with that section, and such building, structure, facility or installation:
      1.   Is constructed at a site at which no other source is located; or
      2.   Totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
      3.   Is constructed for production or wastewater generating processes that are substantially independent of an existing source at the same site, substantial independence being determined by factors such as: a) the extent to which the new facility is integrated with the existing plant; and b) the extent to which the new facility is engaged in the same general type of activity as the existing source.
   B.   Construction on a site at which an existing source is located results in a modification rather than a new source if the construction does not create a new building, structure, facility or installation meeting the criteria of subsection A2 or A3 of this definition, but otherwise alters, replaces or adds to existing process of production equipment.
   C.   For purposes of this definition, construction is deemed to commence when:
      1.   The owner or operator of the facility has entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering and design studies do not constitute a contractual obligation herein; or
      2.   When the following are begun as part of a continuous on-site construction:
         a.   Any placement, assembly or installation of facilities or equipment; or
         b.   Significant site preparation work, including clearing, excavation or removal of existing buildings, structures or facilities, which is necessary for the placement, assembly or installation of new source facilities or equipment.
NEW USER (NEW DISCHARGER): A new user is not a new source and is defined as a user that applies to the city for a new building permit or any person or business that occupies an existing building and plans to discharge wastewater to the city's collection system after the effective date hereof.
OTHER WASTES: Decayed wood, sawdust, shavings, bark, lime, refuse, ashes, garbage, offal, oil, tar, chemicals and all other substances except sewage and industrial wastes.
POTW: Any sewage treatment works owned and operated by the city and the sewers and conveyance appurtenances discharging thereto, whether or not owned by the city. The term also means the city since the U.S. environmental protection agency issues the NPDES permits to the city.
PASS-THROUGH: The occurrence of an indirect discharge that exits the POTW into waters of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the POTW’s NPDES permit (including an increase in the magnitude or duration of a violation).
pH: A measure of the acidity or alkalinity of a substance, expressed in standard units.
POLLUTANT: Any substance discharged into a POTW or its collection system which is prohibited or limited by any section of this chapter. This term includes dredged spoil, solid waste, incinerator residue, sewage, garbage, sewage sludge, munitions, chemical wastes, biological materials, radioactive materials, heat, wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal and agricultural wastes.
PRETREATMENT: The reduction of the amounts 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 a POTW.
PRETREATMENT REQUIREMENT: Any substantive or procedural requirement related to pretreatment, other than a national pretreatment standard, imposed on an industrial user.
PRETREATMENT STANDARDS OR STANDARDS: Prohibited discharge standards, categorical pretreatment standards, local limits and/or BMPs established by the city.

SEPTIC TANK WASTE (SEPTAGE): Any sewage from holding tanks such as vessels, chemical toilets, campers, trailers, and septic tanks.
SEVERE PROPERTY DAMAGE: Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production.
SEWAGE: Water-carried human wastes or a combination of water-carried wastes from residences, business buildings, institutions and industrial establishments.
SEWER: Any pipe, conduit, ditch or other device used to collect and transport sewage from the generating source.
SHALL: "Shall" is mandatory.
SIGNIFICANT CONNECTING USER (SCU): Any private, public or quasi-public reservation, compound, district, government installation, industrial, commercial or domestic complex which indirectly discharges to the POTW at single or multiple connection points to the city’s sewer collection system wastewater mixed with nondomestic wastewater. Upon determination by the wastewater treatment plant superintendent, city clerk or designee that an SCU, as a result of the discharge of toxic pollutants or high strength sewage as measured by BOD and TSS, causes or has the potential to cause interference with the operation and maintenance of the POTW, including its wastewater collection system, causes or has the potential to cause pass-through of pollutants to the receiving waters, or causes or has the potential to cause interference with the treatment, disposal or beneficial reuse of the POTW’s sludge, or that contributes greater than five percent (5%) of the total flow entering the POTW, the city may issue an indirect discharge permit to the SCU. Issuance of an indirect discharge permit may not be necessary if the SCU is regulated by an EPA-approved pretreatment program.
SIGNIFICANT INDUSTRIAL USER (SIU):
   A.   All industrial users of the POTW subject to categorical pretreatment standards under 40 CFR 403.6 and 40 CFR chapter 1, subchapter N.
   B.   Any other industrial user that discharges an average of twenty-five thousand (25,000) gpd (gallons per day) or more of process wastewater to the POTW, excluding sanitary, noncontact cooling and boiler blowdown wastewater; contributes a process waste stream that makes up five percent (5%) or more of the average dry weather hydraulic or organic capacity to the treatment facility receiving the waste; or is designated as such by the city as defined in 40 CFR 403.12(a) on the basis that the industrial user has a reasonable potential, either singly or in combination with other contributing industries, for adversely affecting the POTW’s wastewater collection and treatment system, the quality of sludge, the system’s effluent quality or air emissions generated by the system or for violating any pretreatment standard or requirement.
SIGNIFICANT NONCOMPLIANCE: A. "Chronic violations of wastewater discharge limits", defined herein as those in which sixty six percent (66%) or more of all of the measurements taken for the same pollutant parameter during a six (6) month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined or described in this chapter;
   B.   "Technical review criteria (TRC) violations", defined herein as those in which thirty three percent (33%) or more of wastewater measurements taken for the same pollutant parameter during a six (6) month period equals or exceeds the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined or described in this chapter multiplied by the applicable factor (1.4 for BOD, TSS, fats, oil and grease, and 1.2 for all other pollutants except pH);
   C.   Any other violation of a pretreatment standard or requirement, including instantaneous limits or narrative standard, that the city believes has caused, alone or in combination with other discharges, interference, pass-through, or endangered the health and safety of city personnel or the general public;
   D.   Any discharge of pollutants that has caused imminent endangerment to the public or to the environment, or has resulted in the city's exercise of its emergency authority to halt or prevent such a discharge;
   E.   Failure to meet, within ninety (90) days of the scheduled date, a compliance schedule milestone contained in an indirect discharge permit or enforcement order for starting construction, completing construction, or attaining final compliance;
   F.   Failure to provide within forty-five (45) days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, periodic self-monitoring reports, and reports on compliance with compliance schedules;
   G.   Failure to accurately report noncompliance; or
   H.   Any other violation(s), including a violation of BMPs, which the city determines will adversely affect the operation or implementation of the city's pretreatment program.
SLUG LOAD: Any discharge at a flow rate or concentration which could cause a violation of the discharge standards in any section of this chapter or any discharge of a nonroutine, episodic nature, including, but not limited to, an accidental spill or a non-customary batch discharge.
TOXIC POLLUTANTS: Pollutants or combination of pollutants listed as toxic in regulations promulgated by the administrator of the environmental protection agency under section 307 (33 USC 1317) of the act.
UPSET: An exceptional incident in which a user unintentionally and temporarily is in a state of noncompliance with the standards as set forth in subsections 13.10.040A, B, and sections 13.10.050, 13.10.060, 13.10.070 and 13.10.080 of this chapter due to factors beyond the reasonable control of the user, and excluding noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance or careless or improper operation thereof.
USER: See the definition of Industrial User Or User.
WASTEWATER: Industrial waste, sewage or any other waste, including that which may be combined with any groundwater, surface water or stormwater, that may be discharged to the POTW.
Whenever a reference is made to a rule, regulation, statute, code section, treatise, book, publication, manual, standard, CFR, ordinance or any other regulatory requirement, that reference shall be to the most updated or most recently amended version thereof. (Ord. 1526 § 4, 2023: Ord. 1399, 2015)
