APPLICABLE PRETREATMENT STANDARDS: For any specified pollutant, the "applicable pretreatment standards" shall include the following:
A. General discharge prohibitions;
B. The city's specific limitations on discharge as set forth in this chapter, the NPDES permit or other local ordinance;
C. State standards;
D. Categorical pretreatment standards promulgated by the EPA, or other applicable federal standards or regulations, when effective. Where several standards apply, the most stringent standard shall govern.
AUTHORIZED REPRESENTATIVE OF THE USER: A. If the user is a corporation: the president, secretary, treasurer, vice president or board of directors 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 individuals described in subsections A through C of this definition may designate another authorized representative, if the authorization is in writing and is submitted to the city, and if the authorization specifies the individual or position responsible for the overall operation of the facility from which the discharge originates, or having overall responsibility for environmental matters for the company, organization and/or agency.
BEST MANAGEMENT PRACTICES OR BMPs: Schedules of activities, prohibitions of practices, maintenance procedures and other management practices to implement the prohibitions listed in section 403.5(a)(1) and (b) of the act. BMPs also 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.

A domestic user shall exclude users with nontypical discharges and/or spill potential to the Hailey POTW. Such nontypical users shall be treated as "user" for the purposes of this chapter.
ENVIRONMENTAL PROTECTION AGENCY (EPA): The environmental protection agency or, where appropriate, the regional water management division director, or other duly authorized official of said agency.

EXISTING USER: For noncategorical users, any user which is discharging wastewater prior to the effective date of the ordinance codified herein.
GRAB SAMPLE: A sample which is taken from a waste stream which is representative of a specific time and place without regard to flow.
INDIRECT DISCHARGE OR DISCHARGE: The introduction of pollutants into the POTW from an nondomestic source regulated under section 307(b), (c) or (d) of the act. This discharge into the POTW is normally by means of pipes, conduits, pumping stations, force mains, constructed drainage ditches, surface water intercepting ditches and all constructed devices and appliances appurtenant thereto.
INDUSTRIAL WASTE: Solid, liquid or gaseous waste resulting from any industrial, manufacturing, trade or business process or from the development, recovery or processing of natural resources.

B. Inhibits or disrupts the POTW's sludge processes, use or disposal; or
C. Is a cause of a violation of any requirement of the city's NPDES permit, or to the prevention of sewage sludge use or disposal in compliance with the following statutory provisions and regulations, permits issued thereunder, or more stringent state or location regulations: section 405 of the clean water act; the federal solid waste disposal act (SWDA) (including title II, more commonly referred to as the resource conservation and recovery act (RCRA)); the federal clean air act; the federal toxic substances control act; and state regulations contained in any state sludge management plan prepared pursuant to subtitle D of the SWDA, or in compliance with any other applicable federal legislation.
MAXIMUM ALLOWABLE DISCHARGE LIMIT: The maximum concentration (or loading) of a pollutant allowed to be discharged at any time, determined from the analysis of any discrete or composite sample collected, independent of the industrial flow rate and the duration of the sampling event.

NEW SOURCE:
A. Any building, structure, facility or installation from which there is, or may be, a discharge of pollutants, the construction of which commenced after publication of proposed categorical pretreatment standards under section 307(c) of the clean water act which standards will be applicable to such source if such standards are thereafter promulgated in accordance with that section; provided, that:
1. The building, structure, facility or installation is constructed at a site at which no other source is located; or
2. The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
3. 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, shall be considered.
B. Construction on a site at which an existing source is located and results in a modification of an existing source if the construction does not create a new building, structure, facility or installation meeting the criteria of subsection A of this definition, but otherwise alters, replaces or adds to our existing process or production equipment.
C. Construction of a new source as defined under this definition has commenced if the owner or operator has begun, or caused to begin, as part of a continuous on site construction program:
1. Any placement, assembly or installation of facilities or equipment; or
2. Significant site preparation work, including clearing, excavation or removal of existing buildings, structures or facilities which is necessary for the placement, assembly or installation of new source facilities or equipment.
NEW USER: Is not a "new source" and is defined as a user that applies to the city for a new building permit, or any person who occupies an existing building and plans to discharge wastewater to the city collection system after the effective date hereof.

PRETREATMENT: The reduction of the amount of pollutants, the elimination of pollutants, or the alteration of the nature of pollutant properties in wastewater prior to, or in lieu of, introducing such pollutants into the POTW. This reduction or alteration can be obtained by physical, chemical or biological processes, by process changes, or by other means, but not by diluting the concentration of the pollutants, unless such dilution is allowed by an applicable pretreatment standard.
