   AUTHORIZED REPRESENTATIVE OF USER. An authorized representative of a user is:
      (1)   A responsible corporate officer, if the user is a corporation. 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 principal manager of one or more manufacturing, production, or operation facilities employing more than 250 persons or having gross annual sales or expenditures of more than $25,000,000 in second quarter 1980 dollars, if authority to sign documents has been assigned or delegated to the manager in accordance with corporate procedures.
      (2)   A general partner or proprietor, if the user is a partnership or proprietorship, respectively.
      (3)   The principal executive officer, ranking elected official, or director having responsibility for the overall operation of the discharging facility, if the user is a federal, state or local governmental entity.
      (4)   If none of the categories listed in divisions (1), (2) or (3), above, are applicable to the user, then a representative of the industrial user as approved by the WWTP Superintendent.
      (5)   A duly authorized representative of an individual designated in divisions (1), (2), (3) or (4) 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), (3) or (4) 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 WWTP Superintendent prior to or together with any reports to be signed by the authorized representative.
         b.   If an authorization under division (5)(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 WWTP Superintendent prior to or together with any reports to be signed by the newly authorized representative.
   BOD or BIOCHEMICAL OXYGEN DEMAND. The quantity of oxygen used in the biochemical oxidation of organic matter under standard laboratory procedures for five days at 20 degrees Centigrade, expressed in milligrams per liter (mg/l).
   BUILDING LEAD. The portion of building sewer from the soil pipe to the sewer stub.
   BUILDING SEWER. The portion of a sewer from the soil pipe to the wye branch of the sewer main.
   BYPASS. The intentional diversion of waste streams from any portion of an industrial user's treatment facility.
   CATEGORICAL PRETREATMENT STANDARD. A national pretreatment standard promulgated by the U.S. EPA in accordance with §§ 307(b) and (c) of the Act that specifies quantities or concentrations of pollutants or pollutant properties that may be discharged to a POTW by users in specific industrial subcategories.
   CATEGORICAL USER. Any nondomestic user subject to a categorical pretreatment standard.
   COD or CHEMICAL OXYGEN DEMAND. The quantity of oxygen consumed from a chemical oxidant in a specific test, expressed in milligrams per liter (mg/l).
   CHLORINE DEMAND. The difference between the amount of chlorine applied and the amount of free chlorine available at the end of the contact time, expressed in milligrams per liter (mg/l).
   COMPATIBLE POLLUTANT. A pollutant which, as determined by the WWTP Superintendent, 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 Superintendent may consider, among other factors determined relevant by the Superintendent, 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, phosphorus, 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 POLLUTANTS are “heavy” metals, PCBs, and any other pollutants that will likely contribute or cause operational or sludge disposal problems or unacceptable discharges to the receiving waters, as determined by the WWTP Superintendent.
   COMPOSITE SAMPLE. A series of individual samples 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 sampling, a composite sample shall consist of at least four individual samples taken within a 24-hour period.
   CONTROL AUTHORITY. The Department of Water and Sewer of the Bay County Board of County Road Commissioners acting in its capacity to administer and implement this chapter and the approved industrial pretreatment program.
   CONTROL AUTHORITY ENFORCEMENT RESPONSE PLAN (CAER PLAN). The plan prepared by the POTW as required by 40 C.F.R. § 403.8(f)(5) that describes how the POTW will investigate and respond to instances of non-compliance and the types of escalated enforcement actions the POTW will take in response to violations of applicable standards and requirements.
   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 (NON-CONTACT). Water used for cooling purposes only that has no direct contact with any raw material, intermediate, or final product and that does not contain a detectable level of contaminants higher than that of the intake water or exceed local limits.
   COUNTY. The County of Bay, Michigan.
   DAILY MAXIMUM.  The concentration (or mass loading, expressed in terms of pounds per day) 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. Where daily maximum limitations are expressed in units of mass, the daily discharge is the total mass discharged during the day. Sampling for daily maximum shall be a 24-hour flow proportioned composite sample, except that a minimum of four grab samples shall be taken in lieu of a 24-hour flow proportioned composite sample for pH, cyanide, phenol (T), residual chlorine, oil and grease, sulfides, volatile organic compounds (and any other parameters specified by the WWTP Superintendent). If it is not feasible to obtain a flow proportioned composite sample, a time proportioned composite sample or a minimum of four grab samples may be used in lieu of the flow proportioned composite sample if the user demonstrates to the WWTP Superintendent that a representative sample will be obtained. 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 (except as otherwise provided in a permit, order or agreement issued under this chapter). 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.
   DEPARTMENT. The Department of Water and Sewer of the Bay County Board of County Road Commissioners, or the Department's authorized agents, deputies, or representatives; also referred to as the control authority or the POTW as appropriate to the context herein.

   MONTHLY AVERAGE. The concentration (or mass loading, expressed in terms of pounds per day) that shall not be exceeded for any single calendar month. Where expressed in terms of a concentration, the monthly average limit means the sum of the concentrations of a pollutant obtained through sample analysis during a calendar month divided by the number of samples taken during that calendar month. Where expressed in terms of a mass loading, the monthly average limit means the sum of the daily mass loadings of a pollutant obtained through sample analysis during a calendar month divided by the number of days that mass loading samples were taken during that calendar month. The concentrations (or loadings) that are added are single numbers for single calendar days for all days during the calendar month for which analyses are obtained (whether by the user or the POTW), but the concentrations (or loadings) may be based upon a sample or samples taken over either all or part of that day and upon single or multiple analyses for that day, as determined by the WWTP Superintendent. Sampling for monthly average shall be by composite samples, except that a minimum of four grab samples shall be taken in lieu of a 24-hour flow proportioned composite sample for a single day for pH, cyanide, phenol (T), residual chlorine, oil and grease, sulfide, and volatile organic compounds (and any other parameters specified by the WWTP Superintendent). If it is not feasible to obtain a flow proportioned composite sample, a time proportioned composite sample or a minimum of four grab samples may be used in lieu of the flow proportioned composite sample if the user demonstrates to the WWTP Superintendent that representative samples will be obtained. If the pollutant concentration in any sample is less than the applicable detection limit, that value shall be regarded as zero when calculating the monthly average concentration (except as otherwise provided in a permit, order or agreement issued under this chapter). If no samples are taken during particular months because less than monthly sampling is required for a pollutant parameter (e.g., a specified quarterly monitoring period), the monthly average for each month within the specified monitoring period shall be deemed to be the sum of concentrations (or loadings) for the monitoring period divided by number of samples taken during the monitoring period.
   NATURAL OUTLET. Any outlet into a watercourse, pond, ditch, lake or other body of surface or ground water.
   NEW SOURCE.
      (1)   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 § 307(c) of the Act that will be applicable to the source, if pretreatment standards are thereafter promulgated in accordance with that section, provided that:
         (a)   The building, structure, facility or installation is constructed at a site at which no other source is located; or
         (b)   The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
         (c)   The production or wastewater generating processes of the building, structure, facility or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source should be considered.
      (2)   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 division (b) or (c) of, above, but otherwise alters, replaces, or adds to existing process or production equipment. Commencement of construction of a new source shall be determined in a manner consistent with 40 C.F.R. § 403.3(k)(3).
