§ 53.002  DEFINITIONS.
   For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
   ACT. The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 U.S.C. §§ 1251 et seq.
   AUTHORIZED REPRESENTATIVE. When used in reference to a non-domestic user, AUTHORIZED REPRESENTATIVE means as follows:
      (1)   If the user is a corporation, a RESPONSIBLE CORPORATE OFFICER means: a president, secretary, treasurer, or vice-president of the corporation in charge of a principal business function, or any other person who performs similar policy- or decision-making functions for the corporation; or the manager of one or more manufacturing, production, or operating facilities, provided, the manager is authorized to make management decisions which govern the operation of the regulated facility including having the explicit or implicit duty of making major capital investment recommendations, and initiate and direct other comprehensive measures to assure long-term environmental compliance with environmental laws and regulations; can ensure that the necessary systems are established or actions taken to gather complete and accurate information for control mechanism requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures;
      (2)   If the user is a partnership or proprietorship, a general partner or proprietor, respectively;
      (3)   If the user is a federal, state, or local governmental entity, the principal executive officer, ranking elected official, or director having responsibility for the overall operation of the discharging facility; and
      (4)   A duly authorized representative of an individual designated in divisions (1), (2), or (3) above, if the representative is responsible for the overall operation of the facilities from which the discharge to the POTW originates.
         (a)   To be considered duly authorized, the authorization must be made in writing by an individual designated in divisions (1), (2), or (3) above. The authorization must specify either an individual or a position having responsibility for the overall operation of the facility (such as the position of plant manager, operator of a well or well field, or a position of equivalent responsibility, or having overall responsibility for the environmental matters for the company or entity). The written authorization must be submitted to the POTW Manager prior to or together with any reports to be signed by the AUTHORIZED REPRESENTATIVE.
         (b)   If an authorization under division (4)(a) above 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 or entity, a new written authorization must be submitted to the POTW Manager prior to or together with any reports to be signed by the newly AUTHORIZED REPRESENTATIVE.
   BEST MANAGEMENT PRACTICE or BMP. Any practice, program, procedure, control, technique, or measure (used singularly or in combination) that a user is required to adopt or implement to control, contain, treat, prevent, or reduce the discharge of wastewater, pollutants, or other substances to the POTW, as determined necessary by the POTW Manager. BMPs include, but are not limited to: schedules of activities; pollution treatment practices or devices; prohibitions of practices; good housekeeping practices; pollution prevention, minimization, and reduction measures; educational practices and programs; maintenance procedures; other management programs, practices, or devices; treatment requirements; notice, reporting, and record-keeping requirements; and operating procedures and practices to control or contain site runoff, spillage or leaks, batch discharges, sludge or water disposal, or drainage from product and raw materials storage. BMPs may be structural, nonstructural, or both. In determining what BMPs will be required of a user in a particular case, the POTW Manager may consider all relevant technological, economic, practical, and institutional considerations as determined relevant and appropriate by the Manager, consistent with achieving and maintaining compliance with the requirements of this chapter and other applicable laws and regulations.
   BOD (denoting BIOCHEMICAL OXYGEN DEMAND). The quantity of dissolved oxygen used in the biochemical oxidation of organic matter under standard laboratory procedure in five days at 20°C, expressed in milligrams per liter.
   BUILDING DRAIN. The part of the lowest horizontal piping of a drainage system that receives the discharge from soil, waste, and other drainage pipes inside the walls of a building and conveys it to a building sewer. The BUILDING DRAIN shall be deemed to begin five feet outside the inner face of the building wall.
   BUILDING SEWER. The extension from the building drain to the public sewer or other place of disposal (such as a grinder pump). The BUILDING SEWER shall be deemed to begin five feet outside the inner face of the building wall.
   CATEGORICAL PRETREATMENT STANDARD or CATEGORICAL STANDARD. Any regulation containing pollutant discharge limits promulgated by the EPA in accordance with § 307(b) and (c) of the Clean Water Act, 33 U.S.C. § 1317, which apply to a specific category of users and which appear in 40 C.F.R. chapter I, subchapter N, parts 405 through 471.
   CATEGORICAL USER. A user subject to a categorical pretreatment standard.
   CESSPOOL. An underground pit into which domestic waste is discharged and from which the liquid seeps into the surrounding soil or is otherwise removed.
   C.F.R. Code of Federal Regulations.
   CHLORINE DEMAND. The difference between the amount of chlorine used or present at the beginning of the disinfection process and that available at the end of the contact time, expressed in mg/l.
   COD. A measure of 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 OXYGEN CONSUMED (OCR) and DICHROMATE OXYGEN CONSUMED (DCO), respectively.
   COMBINED SEWER. A sewer intended to receive both wastewater and stormwater.
   COMPATIBLE POLLUTANT. A pollutant that, as determined by the POTW Manager, is susceptible to effective treatment by the POTW, as designed, and which will not interfere with, or pass-through, the POTW, and which is otherwise not incompatible with the treatment processes or in excess of the capacity at the POTW. The term COMPATIBLE is a relative concept that must be determined on a case-by-case basis. In determining whether or not a pollutant is compatible with the POTW, the Manager may consider, without limitation, the nature and qualities of the pollutant, and the concentration, mass, and flow rate at which the pollutant is (or is proposed to be) discharged. Thus, for example, even pollutants such as BOD, fats, oils or grease, phosphorous, suspended solids, and fecal coliform bacteria, which are typically considered COMPATIBLE may be determined incompatible, if discharged in concentrations or flows that would cause interference or pass-through or exceed the POTW’s capacity. Specifically excluded from the definition of COMPATIBLE POLLUTANT are heavy metals, PCBs, and any pollutants that will likely contribute or cause operational or sludge disposal problems or unacceptable discharges to the receiving waters.
   COMPOSITE SAMPLE. A series of individual samples, collected on a flow or time proportional basis, taken at regular intervals over a specific time period and combined into a single sample (formed either by continuous sampling or by mixing discrete samples) representative of the average stream during the sampling period. For categorical, a COMPOSITE SAMPLE shall consist of at least a minimum of one individual aliquot or grab taken every two hours during the discharge period, with a minimum of four individual samples taken during discharge periods of eight hours or less within a 24-hour period.
   COOLING WATER. Water used for cooling purposes only, including both contact and noncontact COOLING WATER.
   COOLING WATER (CONTACT). Water used for cooling purposes only that may become contaminated or polluted either through the use of water treatment chemicals (such as corrosion inhibitors or biocides) or by direct contact with process materials and/or wastewater.
   COOLING WATER (NONCONTACT). Water used for cooling purposes only that has no direct contact with any raw material, intermediate product, final product, or waste, and that does not contain a detectable level of contaminants higher than that of the intake water (for example, the water discharged from uses such as air conditioning, cooling, or refrigeration, or to which the only pollutant added is heat).
   DAILY MAXIMUM. The maximum discharge of pollutants or flow (expressed in terms of concentration, mass loading, pounds, gallons, or other unit of measurement) that shall not be exceeded on any single calendar day. Where DAILY MAXIMUM limitations are expressed in terms of a concentration, the daily discharge is the arithmetic average measurement of the pollutant concentration derived from all measurements taken that day, except pH and dissolved oxygen. 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.
   DAYS. For purposes of computing a period of time prescribed or allowed by this chapter, consecutive calendar DAYS.
   DILUTE. To weaken, thin down, or reduce the concentration of pollutants in wastewater.
   DISCHARGE. The introduction of waste, wastewater, effluent, or pollutants into the POTW, whether intentional or unintentional, and whether directly (such as through an approved sewer connection or other approved DISCHARGE point as authorized by this chapter) or indirectly (including, but not limited to, sources such as inflow and infiltration).
   DOMESTIC USER. A user that discharges only segregated normal strength domestic waste into the POTW.
   DOMESTIC WASTE. Wastewater (or water-carried waste) of human origin generated by personal activities from toilet, kitchen, laundry, or bathing facilities, or by other similar facilities used for household or residential dwelling purposes (“sanitary sewage”). DOMESTIC WASTE shall not include any waste resulting from industrial or commercial processes including, without limitation, any hazardous or toxic pollutants. Wastes that emanate from sources other than residential dwelling units may be considered DOMESTIC WASTES only if they are of the same nature and strength and have the same flow rate characteristics as wastes that emanate from residential dwelling units.
   EFFLUENT. Wastewater or other liquid, partially or completely treated, flowing from a reservoir, basin, treatment process, or treatment plant.
   EPA. The United States Environmental Protection Agency.
   EXCESSIVE. At such a flow, rate, magnitude, or amount that, in the judgment of the POTW Manager, it may: cause damage to any facility or the POTW; be harmful to the wastewater treatment processes; adversely affect the management or operation of the POTW or POTW sludge management or disposal; cause pass-through or interference; violate any pretreatment standard or requirement; adversely affect the quality of the receiving waters or the ambient air quality; endanger worker health and safety; constitute a public nuisance; may be inconsistent with the requirements, purposes, or objectives of this chapter; or otherwise adversely impact the public health, safety, or welfare or the environment.
