A general partner or proprietor if the industrial user is a partnership or proprietorship, respectively.

BEST MANAGEMENT PRACTICES (BMPs)

A duly authorized representative of the individual designated above and if all of the following apply:

(a)

The authorization is made in writing by the individual described in Subsections (1) or (2) of this definition;

(b)

This authorization specifies either an individual or a position having responsibility for the overall operation of the facility from which the industrial discharge originates, such as the position of plant manager, operator of a well, or well field superintendent, or a position of equivalent responsibility, or having overall responsibility for environmental matters for the company; and

(c)

The written authorization is submitted to the Director. If an authorization is no longer accurate because a different individual or position has responsibility for the overall operation of the facility, or overall responsibility for environmental matters for the company, a new authorization satisfying the requirements of this definition shall be submitted to the Director prior to or together with any reports to be signed by an authorized representative.

AVAILABLE CYANIDE

The quantity of cyanide that consists of cyanide ion (CN), hydrogen cyanide in water (HCNaq), and the cyano-complexes of zinc, copper, cadmium, mercury nickel and silver, determined by EPA method OIA-1677, or other method designated as a standard method or approved under 40 CFR 136.

Programs, practices, procedures or other directed efforts, initiated and implemented by the user, which can or do lead to the reduction, conservation or minimization of pollutants being introduced into the ecosystem, including but are not limited to the Ypsilanti Community Utilities Authority (YCUA) or City of Detroit publicly owned treatment systems. BMPs include, but are not limited to, equipment or technology modifications, process or procedure modifications, reformulation or design of products, substitution of raw materials, and improvements in housekeeping, maintenance, training, or inventory control and may include technical and economic considerations. BMPs may be structural or nonstructural or both. In determining what BMPs will be required of a user in a particular case, the Director may consider all relevant technological, economical, practical, and institutional considerations as determined relevant and appropriate by the Director, consistent with achieving and maintaining compliance with the requirements of this chapter and other applicable laws and regulations.

BEST MANAGEMENT PRACTICES PLAN (BMPP)

A written document that describes how the BMPs will be accomplished.

BIOCHEMICAL OXYGEN DEMAND (BOD)

The quantity of oxygen utilized in the biochemical oxidation of organic matter under standard laboratory procedure, five days at 20° C. expressed in terms of weight and concentration (milligrams per liter).

BOARD

The Board of Trustees of Northville Charter Township.

BUILDING DRAIN

That part of the lowest horizontal piping of a drainage system which receives the drainage from soil, waste and other drainage pipes inside the walls of the building and conveys it to the building sewer, beginning five feet outside the inner face of the building wall.

BUILDING SEWER

That extension from the building drain to the public sewer or other places of disposal.

BYPASS

Intentional diversion of waste streams from any portion of an industrial user's treatment facility.

CHEMICAL OXYGEN DEMAND (COD)

A measure of the oxygen-consuming capacity of inorganic and organic matter present in water or wastewater. It is expressed as the amount of oxygen consumed from a chemical oxidant in a specified test. It does not differentiate between stable and unstable organic matter and thus does not necessarily correlate with biochemical oxygen demand. Also known as "OC" and "DOC," oxygen consumed and dichromate oxygen consumed, respectively.

CHLORINE DEMAND

The difference between the amount of chlorine added to water or wastewater and the amount of residual chlorine remaining at the end of a specified contact period. The demand for any given water varies with the amount of chlorine applied, time of contact and temperature.

COMBINED SEWER

A sewer receiving both surface runoff and sewage.

COMBINED WASTE STREAM

The waste stream at industrial facilities where regulated process effluent is mixed with other wastewaters (either regulated or unregulated) prior to treatment.

COMPATIBLE POLLUTANT

A substance amenable to treatment in the wastewater treatment plant such as biochemical oxygen demand, suspended solids, pH and fecal coli form bacteria, plus additional pollutants identified in the National Pollution Discharge Elimination System (NPDES) permit if the publicly owned treatment works was designed to treat such pollutants, and in fact does remove such pollutant to a substantial degree. Examples of such additional pollutants may include chemical oxygen demand (COD), total organic carbon, and phosphorus and phosphorus compounds, nitrogen compounds, fats, oils and greases of animal or vegetable origin.

COMPOSITE SAMPLE

A sample formed either by continuous sampling or by mixing discrete samples obtained at intervals over a period of time. The individual samples shall be obtained through flow-proportional composite sampling techniques, unless time-proportional composite sampling or grab sampling is authorized by DWSD or YCUA. Where time-proportional composite sampling or grab sampling is authorized by DWSD or YCUA, the samples must be representative of the discharge. Manual generation of a composite sample through the collection and combining of grab samples may be approved if the user demonstrates to the satisfaction of the Director that this will provide a representative sample of the effluent being discharged.

DEPARTMENT OF NATURAL RESOURCES AND ENVIRONMENT or DNRE

The decision to allow the alternative sampling must be documented in the industrial user's file for that facility or facilities. Composite sampling protocols delineated in the user's permit take precedence.

COOLING WATER

The water discharged from any use such as air conditioning, cooling or refrigeration, or to which the only pollutant added is heat.

DAILY MAXIMUM

The concentration or mass loading that shall not be exceeded on any single calendar day. Where daily maximum limitations are expressed in terms of concentration, the daily discharge is the arithmetical average measurement of the pollutant concentration derived from all measurements taken that day. Where daily maximum limitations are expressed in units of mass, the daily discharge is the total mass discharged during the day. If a composite sample is required for a parameter, the determination whether the daily maximum limitation for that parameter has been exceeded on a single calendar day shall be based on the composite sample collected for that parameter on that calendar day. If grab samples are required for a parameter, the determination whether the daily maximum limitation for that parameter has been exceeded on a calendar day shall be based on the average of all grab samples collected for that parameter on that calendar day. If only one grab sample is collected for a parameter on a given day, the determination whether the daily maximum limitation for that parameter has been exceeded for the day shall be based on the results of that single grab sample. If the pollutant concentration in any sample is less than the applicable detection limit, that value shall be regarded as zero when calculating the daily maximum concentration.

INSTANTANEOUS MAXIMUM CONCENTRATION

The maximum concentration of a pollutant allowed to be discharged at any instant in time (independent of the flow rate or duration of the sampling event). If the concentration determined by analysis of any grab sample, composite sample, or discrete portion of any composite sample exceeds the instantaneous maximum concentration, the instantaneous maximum concentration shall be deemed to have been exceeded.
