On June 6 th 1991, the United States Environmental Protection Agency (EPA) through the State of Utah Division of Water Quality approved the St. George City Pretreatment Program.
The St. George City Pretreatment Program has been delegated primary responsibility for enforcing against discharges prohibited by 40 CFR 403.5 and applying and enforcing any national Pretreatment Standards established by the United States EPA in accordance with Section 307(b) and (c) of the Clean Water Act (CWA), as amended by the Water Quality Act (WQA), of 1987.
The General Pretreatment Regulations set responsibilities for federal, state, local government, industry, and the public to achieve the National Pretreatment Program Objectives.
Publicly Owned Treatment Works, (POTW) collect wastewater from homes, commercial buildings, and industrial/ commercial facilities and/or locations. This wastewater leaves these locations through a complex series of underground sewer lines called the sanitary wastewater collection system. The collection system transports wastewater to the POTW in Bloomington called the St. George Regional Water Reclamation Facility, (SGRWRF). Once the wastewater enters the SGRWRF, it is directed through a series of treatment technologies effectively removing harmful organisms and other contaminants.
Generally, POTW’s are designed to treat domestic sewage only. The SGRWRF is no exception to this point. However, as with other cities, the SGRWRF also receives wastewater from industrial and commercial sources, (non-domestic).
The General Pretreatment Standards and Regulations establish legal responsibilities of Federal, State, Local government, industry and the public to implement applicable Pretreatment Standards. The Pretreatment Standards protect the SGRWRF from pollutants which may pass through or interfere with the SGRWRF treatment processes or which may contaminate the beneficial use of the SGRWRF sewage sludge, (i.e. Biosolids).
“Pretreatment” is also defined in Title 40 Code of Federal Regulations (40 CFR) Subsection 403.

Categorical Pretreatment Standards limit the pollutant discharges to POTWs from specific process wastewaters of particular industrial categories. These national technology-based standards apply regardless of whether or not the POTW has an approved pretreatment program or the Industrial User (IU) has been issued a control mechanism or permit. Such industries are called Categorical Industrial Users. The standards are promulgated by EPA in accordance with Section 307 of the Clean Water Act and are designated in the Effluent Guidelines & Limitations [ Parts 405-4071] by the terms “Pretreatment Standards for Existing Sources (PSES)” and “ Pretreatment Standards for New Sources (PSNS)”.
Local Limits reflect the specific needs and capabilities at individual POTWs and are designed to protect the POTW, its receiving waters, and its sludge disposal practices. Regulations at 40 CFR 403.8(f) (4) state that the POTW Pretreatment Program must develop Local Limits or demonstrate that they are unnecessary; 40 CFR 403.5(c) states that Local Limits are needed when pollutants are received that could result in pass through or interference at the POTW. Essentially, Local Limits translate the General Prohibited Discharge Standards of 40 CFR 403.5 to site-specific needs.
Prohibited Discharge Standards forbid the discharge of any pollutant(s) to a POTW that causes pass through or interference. These national standards apply to all industrial and commercial users that
discharge to a POTW, regardless of whether or not the POTW has an approved pretreatment program or whether the industrial user has been issued a control mechanism or permit. These standards are
intended to provide general protection for POTW’s, despite their lack of specific pollutant limitations. Thus, the needs for additional controls are incorporated, namely Categorical Pretreatment Standards
and Local Limits. The Prohibited Discharge Standards are listed in Title (8) Chapter (4) of the St. George City Ordinance.
Discharge permits are issued to significant/categorical industrial users. Certain conditions must be met in order to continue to discharge wastewater into the City sewer system. These requirements include yet are not limited to controlling the quality of their discharge by installing appropriate treatment systems that will “pretreat” their effluent prior to discharge to the sewer system.
Significant Industrial Users (SIU) and Categorical Industrial Users (CIU) include:
SGRWRF created a "Special Discharge" permit program specifically for these types of discharges. Call (435) 627-4266 for permit program information and a permit application.
Please call the St. George Regional Water Reclamation Facility (SGRWRF) at (435) 627-4266. It would be helpful to tell us the discharge or spill location, color, approximate volume and if the discharge is ongoing. An SGRWRF representative will investigate the occurrence or refer you to the proper agency.
In addition to SGRWRF wastewater discharge limits, some facilities may be subject to federal regulations. The federal regulations can be viewed on the U.S. EPA website by typing “Subchapter N - Effluent Guidelines and Standards” in the Search Box and selecting “Parts 400 – 424” or “Parts 425 – 471”.
Pollution prevention is the reduction and control of pollutants before discharge to the sanitary sewer. SGRWRF developed a Pollution Prevention Program, which focuses on waste reduction and elimination through permit requirements to select commercial businesses, and education and public outreach to all customers.
Pollution prevention can eliminate or reduce many costs for commercial and industrial users by avoiding permit fees, chemical costs, and disposal charges while helping SGRWRF to reduce the discharge of pollutants to the wastewater treatment plant and the Virgin River.
The U.S. EPA requires SGRWRF to control discharges to the sanitary sewer. This control is necessary to protect personnel working in the collection and treatment system, to protect the collection system and treatment plant itself from discharges that can interfere with its normal operations, and to prevent pollutants from passing through the treatment plant into the Virgin River.
SGRWRF began a Pretreatment Program to meet these requirements in 1991. A Pretreatment Program was developed including issuance of industrial permits to help businesses meet regulations for discharges to the sanitary sewer. The Pollution Prevention Program focuses on waste reduction, control and elimination through permits to selected commercial businesses, and education and public outreach to all customers.
Several different permit types regulate industrial wastewater discharges to the sanitary sewer as well as trucked wastes accepted at the SGRWRF wastewater treatment plant in Bloomington. Get more information about SGRWRF's Permit Program by calling (435) 627-4266.
Wastes currently accepted are: Portable toilet; septic tank waste; carpet cleaning wastewater; and treated food truck wastewater.
Permit applications for SGRWRF’s wastewater permit programs can be obtained by calling (435) 627-4266.
A Wastewater Discharge Application can be obtained by contacting the City Business License Department, calling (435) 627-4266, or clicking the link- Wastewater Discharge Application (FSE).
The following public entities own and/or operate wastewater collection systems within SGRWRF's wastewater service area.
Select commercial businesses are permitted in SGRWRF’s Pollution Prevention Program. Business types are chosen based on the pollutants that the businesses generate and SGRWRF’s need to reduce and control the pollutants discharged to the sanitary sewer. The place to get started is to complete an Industrial Waste Survey.
Permits are required for many reasons, depending on type of business, the volume and characteristics of wastewater discharged and the potential risk or impact to the collection system and wastewater treatment plant, SGRWRF personnel, or the Virgin River. Get information on permit requirements by calling (435) 627-4266.
