This chapter sets forth uniform requirements for users of the publicly owned treatment works for the St. George regional water reclamation facility and enables the city of St. George to comply with all applicable state and federal laws, including the Clean Water Act (33 USC section 1251 et seq.), the General Pretreatment Regulations (title 40 of CFR part 403), and the UAC R317-8-8. This chapter shall apply to all users of the publicly owned treatment works. This chapter authorizes the issuance of individual wastewater discharge permits; authorizes monitoring, compliance, and enforcement activities; establishes administrative review procedures; requires user reporting; and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein. The objectives of this chapter are:

A. To prevent the introduction of pollutants into the publicly owned treatment works that will interfere with its operation or contaminate the resulting sludge;

B. To prevent the introduction of pollutants into the publicly owned treatment works that will pass through the publicly owned treatment works, inadequately treated, into receiving waters, the atmosphere, or otherwise be incompatible with the publicly owned treatment works;

C. To ensure that the quality of the wastewater treatment plant sludge is maintained at a level which allows its use and disposal in compliance with applicable statutes and regulations found in 40 CFR part 503;

D. To protect both publicly owned treatment works personnel who may be affected by wastewater and sludge in the course of their employment, and the general public;

E. To promote reuse and recycling of wastewater and sludge from the publicly owned treatment works;

F. To provide for fees for the equitable distribution of the cost of operation, maintenance, and improvement of the publicly owned treatment works; and

G. To enable SGRWRF to comply with its Utah pollutant discharge elimination system permit conditions, sludge use and disposal requirements, and any other federal or state laws to which the publicly owned treatment works is subject. (Ord. 2016-11-005, 11-10-2016)

A. 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 section 307(c) of the Act that 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, should be considered.

B. 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 subsection A2 or A3 of this definition but otherwise alters, replaces, or adds to existing process or production equipment.

C. Construction of a new source as defined herein has commenced if the owner or operator has:

1. Begun, or caused to begin, as part of a continuous on-site construction program:

2. Entered into a binding contractual obligation for the purchase of facilities or equipment which are intended to be used in its operation within a reasonable time. Options to purchase or contracts which can be terminated or modified without substantial loss, and contracts for feasibility, engineering, and design studies do not constitute a contractual obligation under this definition.

NONCONTACT COOLING WATER: Water used for cooling that does not come into direct contact with any raw material, intermediate product, waste product, or finished product.

PASS-THROUGH: A discharge which exits the POTW into waters of the state in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of SGRWRF’s UPDES permit, including an increase in the magnitude or duration of a violation.

PERSON: Any individual, partnership, copartnership, firm, company, corporation, limited liability company, association, joint stock company, trust, estate, governmental entity, or any other legal entity, or their legal representatives, agents, or assigns.

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 a) physical, chemical, or biological processes; b) process changes; or c) other means. Pretreatment cannot be obtained by diluting the concentration of the pollutants, unless allowed by an applicable pretreatment standard.

PRETREATMENT COORDINATOR: The person designated by SGRWRF to coordinate the SGRWRF pretreatment program, charged with certain duties and responsibilities under this chapter as directed and delegated by the manager. A technically skilled position, the pretreatment coordinator, or his or her designee, performs surveillance, administrative duties, and related work in monitoring compliance, and is a liaison with IUs of the SGRWRF.

PRETREATMENT STANDARDS OR STANDARDS: Pretreatment standards shall mean any regulation containing pollutant discharge limits promulgated by the EPA in accordance with section 307(b) and (c) of the act, which applies to IUs, which includes, but is not limited to, prohibited discharge standards, categorical pretreatment standards, and local limits.

PUBLICLY OWNED TREATMENT WORKS OR POTW: A treatment works, as defined by section 212 of the Act (33 USC section 1292), which is owned by the SGRWRF. This definition includes any devices or systems used in the collection, storage, treatment, recycling, and reclamation of sewage or industrial wastes of a liquid nature, and any conveyances, which convey wastewater to a treatment plant. It also includes sewers, pipes and other conveyances if they convey wastewater to a POTW.

A. An industrial user subject to categorical pretreatment standards; or

B. An industrial user that:

1. Discharges an average of twenty five thousand (25,000) gpd or more of process wastewater to the POTW (excluding sanitary, noncontact cooling, and boiler blowdown wastewater);

2. Contributes a process waste stream which makes up five percent (5%) or more of the average dry weather hydraulic or organic capacity of the POTW treatment plant; or

3. Is designated as such by SGRWRF on the basis that it has a reasonable potential for adversely affecting the POTW’s operation, or for violating any pretreatment standard or requirement.

C. Upon a finding that a user meeting the criteria in subsection B of this definition has no reasonable potential for adversely affecting the POTW’s operation, or for violating any pretreatment standard or requirement, SGRWRF may at any time, on its own initiative, or in response to a petition received from an industrial user, and in accordance with procedures in 40 CFR section 403.8(f)(6), determine that such user should not be considered a significant industrial user.
