Waste constituents and characteristics shall be measured by Standard Methods unless a mutually agreed upon acceptable alternative method is adopted between the concerned parties, or as established by state or federal regulatory agencies. Monitoring shall be carried out by customarily accepted methods. 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 (PL92-500) as amended by the Clean Water Act (PL 95-217) of 1977.

APPROVED AUTHORITY. The Director in an NPDES state with an approved state pretreatment program or the Administrator of the EPA in a non-NPDES state or an NPDES state without an approved state pretreatment program.
AUTHORIZED REPRESENTATIVE OF INDUSTRIAL USER. An authorized representative of an industrial user may be:
(1) A principal executive officer of at least the level of vice-president, if the industrial user is a corporation;
(2) A general partner or proprietor if the industrial user is a partnership or proprietorship, respectively; or
(3) A duly authorized representative of the individual designated above if such representative is responsible for the overall operation of the facilities from which the indirect discharge originates.
AVERAGE MONTHLY DISCHARGE LIMITATION. The highest allowable average of “daily discharges” over a calendar month calculated as the sum of all daily discharges measured during a calendar month divided by the number of daily discharges measured during that month.
AVERAGE WEEKLY DISCHARGE LIMITATION. The highest allowable average of “daily discharges” over a calendar week, calculated as the sum of all daily discharges measured during a calendar week divided by the number of daily discharges measured during the week.
COMPOSITE SAMPLES. A composite sample should contain a minimum of eight discrete samples taken at equal time intervals over the compositing period or proportional to the flow rate over the compositing period. More than the minimum number of discrete samples will be required where the wastewater loading is highly variable.
DAILY DISCHARGE. Discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling.
EASEMENT. An acquired legal right, for the specific use of land owned by others.
EPA. The United States Environmental Protection Agency, or where appropriate, the term may also be used as a designation for the administrator or other duly authorized official of the agency.
FEDERAL ACT. Same as ACT.
GRAB SAMPLE. A sample which is taken from a wastestream on a one-time basis with no regard to the flow in the wastestream and without consideration of time.
HOLDING TANK WASTE. Any waste from holding tanks, such as chemical toilets, campers, trailers, septic tanks, vacuum pump trucks and the like
INDUSTRIAL USER. Any industrial or commercial establishment that discharges industrial (process) wastewater to a publicly-owned treatment works.
INDUSTRIAL WASTE PERMIT. A permit to deposit or discharge industrial waste into any sanitary sewer as issued by the POTW.
INFLUENT. The water together with any wastes that may be present flowing into a drain, sewer, receptacle or outlet.
INTERFERENCE. The inhibition or disruption of the POTW treatment processes or operations which contribute to a violation of any requirement of the city’s NPDES permit. The term includes prevention of sewage sludge use or disposal by the POTW in accordance with 405 of the Act (33 W.S.C. 1345) or any criteria, guidelines or regulations developed pursuant to the Solid Waste Disposal Act or regulations (SWDA), the Clean Air Act, the Toxic Substance Control Act, 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.
(3) A duly authorized representative of the individual designated above if such representative is responsible for the overall operation of the facilities from which the indirect discharge originates.
AVERAGE MONTHLY DISCHARGE LIMITATION. The highest allowable average of “daily discharges” over a calendar month calculated as the sum of all daily discharges measured during a calendar month divided by the number of daily discharges measured during that month.
AVERAGE WEEKLY DISCHARGE LIMITATION. The highest allowable average of “daily discharges” over a calendar week, calculated as the sum of all daily discharges measured during a calendar week divided by the number of daily discharges measured during the week.
COMPOSITE SAMPLES. A composite sample should contain a minimum of eight discrete samples taken at equal time intervals over the compositing period or proportional to the flow rate over the compositing period. More than the minimum number of discrete samples will be required where the wastewater loading is highly variable.
DAILY DISCHARGE. Discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling.
INDUSTRIAL WASTE. Trade or process waste emanating from industrial discharge.
MAXIMUM DAILY DISCHARGE LIMITATION. Highest allowable “daily discharge.”
MAY. Indicates a discretionary condition.
NATIONAL CATEGORICAL PRETREATMENT STANDARD or PRETREATMENT STANDARD. Any regulation containing pollutant discharge limits promulgated by the EPA in accordance with Section 307(b) and (c) of the Act which applies to a specific category of industrial users.
NEW SOURCE. Any source the construction of which is started after the publication of proposed regulations stating a categorical pretreatment standard will be applicable to such source, provided the standard is promulgated within 120 days of its proposal in the Federal Register. Where the standard is promulgated later than 120 days after its proposal, a new source means any source in which construction is started after the date of promulgation of the standard.
PERSON. Any and all persons, including any individual, firm, company, municipal or private corporation, partnership, co-partnership, joint stock company, trust, estate, association, society, institution, enterprise, governmental agency, the State of Indiana, the United States of America, or other legal entity, or their legal representatives, agents or assigns.

SLUDGE. Any solid, semi-solid or liquid waste generated from a municipal, commercial or industrial wastewater treatment plant, water supply treatment plant, or air pollution control facility, or any other wastes having similar characteristics and effects as defined in standards issued under Section 402 and 405 of the Federal Act and in the applicable requirements under Sections 3001, 3004 and 4004 of the Solid Waste Disposal Act PL 94-580.
