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.
Regulate the disposal of industrial wastewater into the sanitary wastewater collection system.
Protect the physical structures and the safety of operation; maintenance personnel of the sanitary wastewater collection system and the SGRWRF.
Protect the health and safety of the public and the environment.
Comply with Pretreatment Regulations as required under the Federal General Pretreatment Regulations and Categorical Standards and the St. George City Pretreatment Ordinance Title 8 Chapter 4: Pretreatment Ordinance.
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:
All users subject to Federal categorical pretreatment standards under Title 40 of the Code of Federal Regulations
Any user that discharges an average of 25,000 gallons or more a day of process wastewater in the City sewer system.
Any user that contributes a process wastestream which comprises 5% or more of the treatment plant flow.
Any user of the sanitary wastewater collection system can be designated a SIU on the basis that it has reasonable potential to adversely affect the treatment plant operations or violating any pretreatment standard or requirement.
