Schedules of activities, prohibitions of practices, maintenances procedures, and other management practices to implement the prohibitions listed in §§ 52.42 and 52.44. BMPs include treatment requirements, operating procedures, and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from raw materials storage. BMPs also include alternative means (i.e., management plans) of complying with, or in place of certain established categorical pretreatment standards and effluent limits.

COMPATIBLE POLLUTANT. BOD, suspended solids, pH and fecal coliform bacteria, plus additional pollutants identified in the NPDES permit, if the publicly owned treatment works was designed to treat such pollutants, and in fact does remove such pollutants to a substantial degree. Examples of such
additional pollutants may include: (1) COD; (2) total organic carbon; (3) phosphorus and phosphorus compounds; (4) nitrogen and nitrogen compounds; (5) fats, oils and greases of animal or vegetable origin, except as prohibited under § 52.63.

INDUSTRIAL USER. Any user who discharges “industrial wastes” as defined in this section.
INDUSTRIAL WASTES. The wastewater from industrial processes, trade or business, as distinct from sanitary sewage.
INTERFERENCE. An industrial discharge which, alone or in conjunction with discharges by other sources, both (a) inhibits or disrupts the publicly owned treatment works, its treatment processes operations, or it sludge processes, use or disposal; and (b) therefore is a cause of a violation of any requirement of the POTW’s National Pollutant Discharge Elimination System permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge disposal by the POTW in accordance with Section 405 of the Act (33 U.S.C. § 1345) or any criteria, guidelines or regulations developed pursuant to the Solid Waste Disposal Act (SWDA), the Clean Air Act, the Toxic Substances Control Act, Resource Conservation and Recovery Act (RCRA) or more stringent state criteria (including those contained in any state sludge management plan prepared pursuant to Title IV of SWDA) applicable to the method of disposal or use employed by the POTW.
MAY is permissive; SHALL is mandatory.
NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake or other body of surface water or groundwater.
NPDES PERMIT. The National Pollutant Discharge Elimination System permit.
OWNER or PERSON. Any individual, firm, company, association, society, corporation or group.
PASS-THROUGH. A discharge that exits the POTW into waters of the state 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. The reciprocal of the logarithm of the hydrogen ion concentration. The concentration is the weight of hydrogen ions, in grams, per liter of solution. Neutral water, for example, has a pH value of 7 and a hydrogen ion concentration of 10-7.
POLLUTANT. Dredged spoil, solid waste, incinerator residue, wastewater, garbage, wastewater sludge, munitions, wrecked or discarded equipment, rock, sand, cellar dirt and industrial, municipal and agricultural waste discharged into water.
PRETREATMENT. The treatment of wastewaters from sources before introduction into the POTW.
PROPERLY SHREDDED GARBAGE. The wastes from preparation, cooking and dispensing of food that have been shredded to such a degree that all particles will be carried freely under the flow conditions normally prevailing in public sewers, with no particle greater than 0.5 inch in any dimension.
PUBLIC SEWER. A common sewer controlled by a governmental agency or public utility.
PUBLICLY OWNED TREATMENT WORKS (POTW). Any devices or systems used in the collection, storage, treatment, recycling, and reclamation of sewage or industrial wastes of a liquid nature and any conveyances which convey wastewater to a treatment plant.
SANITARY SEWAGE. Wastewater contributed by reason of human occupancy.
SANITARY SEWER. A sewer that carries liquid and water-carried wastes from residences, commercial buildings, industrial plants and institutions and to which ground, storm and surface waters are not admitted intentionally.
SEWER. A pipe or conduit for carrying wastewater or storm water.
SEWER CONTRACTOR. The agent of the owner responsible for the construction of the building sewer.
SIGNIFICANT INDUSTRIAL USER (SIU).
(1) All Industrial Users subject to Categorical Pretreatment Standards under 40 C.F.R. § 403.6 and 40 C.F.R. Chapter I, Subchapter N; discharging to the POTW; or
(2) Any other industrial users that: discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary, non-contact cooling and boiler blowdown wastewater); contributes a process waste stream which makes up 5% or more of the average dry weather hydraulic or organic capacity of the wastewater treatment plant; or
(3) Is designated as such by the POTW 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 C.F.R. § 403.8(f)(6)).
SIGNIFICANT NONCOMPLIANCE.
(1) Chronic violations of wastewater discharge limits, defined here as those in which 66% or more of all of the measurements taken during a six-month period exceed (by any magnitude) the daily maximum limit or the average limit for the same pollutant parameter;
(2) Technical review criteria (TRC) violations, defined here as those in which 33% or more of all of the measurements for each pollutant parameter taken during a six-month period equal or exceed the product of the daily maximum limit or the average limit multiplied by the applicable TRC (TRC=1.4 for BOD, TSS, fats, oil, and grease, and 1.2 for all other parameters except pH);
(3) Any other violation of a pretreatment effluent limit (daily maximum or long-term average) that the Village Administrator determined has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of POTW personnel or the general public);
