Cedar City Pretreatment Program

About the Pretreatment Program
On April 1st 1996, the United States Environmental Protection Agency (EPA) through the State of Utah Division of Water Quality approved the Cedar City Pretreatment Program.

The Cedar 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 under-ground sewer lines called the sanitary wastewater collection system. The collection system transports wastewater to the POTW here called the Cedar City Regional Wastewater Treatment Facility, (CCRWTF). Once the wastewater enters the CCRWTF, it is directed through a series of treatment technologies effectively removing harmful organisms and other contaminants.

Generally, POTWs are designed to treat domestic sewage only. The CCRWTF is no exception to this point. However, as with other cities, the CCRWTF 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 CCRWTF from pollutants which may pass through or interfere with the CCRWTF treatment processes or which may contaminate the beneficial use of the CCRWTF sewage sludge, (i.e. Biosolids).

"Pretreatment" is also defined in the Title 40 Code of Federal Regulations (40 CFR) Subsection 403.

Objectives of Pretreatment Program


  • 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 CCRWTF.
  • 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 Cedar City Pretreatment Ordinance 30a.

Prohibited Discharge Standards:



Prohibited Discharge Standards forbid the discharge of any pollutant(s) to a POTW that cause 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 POTWs.  However, their lack of specific pollutant limitations.  Thus, the need for additional controls are incorporated, namely Categorical Pretreatment Standards and Local Limits. The Prohibited Discharge Standards are listed in 40 CFR 403.5 

Categorical Pretreatment Standards:



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 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 405-471] by the terms "Pretreatment Standards for Existing Sources (PSES)" and "Pretreatment Standards for New Sources (PSNS)".

Local Limits:


 
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 POTW Pretreatment Programs 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.


Significant Industrial Users and Categorical Industrial User Permitting:

Discharge permits are issued to significant/categorical industrial users. The permits are valid for two years and list certain requirements and conditions that 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. Please refer to

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 into the City sewer system.
  • Any user that contributes a process waste stream 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 a reasonable potential to adversely affect the treatment plant operation or violating any pretreatment standard or requirement.
