INTERFERENCE.
An inhibition or disruption of the sewage treatment plant, its treatment processes or operations, or its sludge processes, use or disposal which is a cause of or significantly contributes to either a violation of any requirement of the sewage treatment plant's NPDES permit (including an increase in the magnitude or duration of a violation) or to the prevention of sewage sludge use or disposal by the treatment plant in accordance with the following statutory provisions and regulations or permits issued thereunder (or more stringent state or local regulations): Section 405 of the Clean Water Act, the Solid Waste Disposal Act (SWDA) (including Title II more commonly referred to as the Resource Conservation and Recovery Act (RCRA) and including state regulations contained in any state sludge management plan prepared pursuant to Subtitle D of the SWDA), the Clean Air Act, and the Toxic Substances Control Act. A user significantly contributes to such a violation or prevention of sludge use or disposal in accordance with above-cited authorities whenever such user:
(A) Discharges a daily pollutant loading in excess of that allowed by federal, state, or local law;
(B) Discharges wastewater which substantially differs in nature or constituents from the user's average discharge;
(C) Knows or has reason to know that its discharge, alone or in conjunction with discharges from other sources, would result in a sewage treatment plant permit violation or prevent sewage sludge use or disposal in accordance with the above-cited authorities as they apply to the village's selected method of sludge management.
MAJOR CONTRIBUTING INDUSTRY.
An industrial user that has a flow of 50,000 gallons or more per average work day, or has a flow greater than 10% of the flow carried by the sewerage works receiving the waste, or has in its waste a toxic pollutant in toxic amounts and defined in standards issued under § 307(a) of the Federal Act, or is found by the permit issuance authority, in connection with the issuance of the NPDES permit to the publicly owned treatment works receiving the waste, to have significant impact, either singly or in combination with other contributing industries, on that treatment works or upon the quality of effluent from that treatment works.
mg/l.
Milligrams per liter.
MULTIPLE USER.
Any additional number of residential, commercial, or industrial units located on the same premises, or being served through a single water meter such as apartment buildings, more than one commercial or industrial unit in the same building, or residential and commercial units located in the same building.
NATIONAL CATEGORICAL PRETREATMENT STANDARD.
Any pretreatment standard specifying quantities or concentration of pollutants which may be discharged to a POTW by industrial users in specific industrial subcategories as established in regulations promulgated from time to time by the USEPA in 40 CFR Chapter I, Subchapter N.

NPDES PERMIT.
Any permit or equivalent document to regulate the discharge of pollutants pursuant to § 402 of the Federal Act.
PASS THROUGH.
The discharge of pollutants through the sewage treatment plant into navigable waters in quantities or concentrations which are a cause of or significantly contribute to a violation of any requirement of the treatment plant's NPDES permit (including an increase in the magnitude or duration of a violation). A user significantly contributes to such permit violation whenever such user:
(A) Discharges a daily pollutant loading in excess of that allowed by federal, state, or local law;
(B) Discharges wastewater which substantially differs in nature and constituents from the user's average discharge;
(C) Knows or has reason to know that its discharge, along or in conjunction with discharges from other sources, would result in a permit violation;
(D) Knows or has reason to know that the sewage treatment plant is, for any reason, violating its final effluent limitations in its permit and that such user's discharge either alone or in conjunction with discharges from other sources, increases the magnitude or duration of the sewage treatment plant's violations.
pH.
The logarithm (base 10) of the reciprocal of the hydrogen-ion concentration expressed in gram molecular weight (moles) per liter.
