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.


Industrial User, (IU) Significant Industrial User, (SIU) and Categorical Industrial User (CIU) Permitting:

Wastewater Discharge Permits:
Wastewater Discharge Permits are issued to Industrial Users, (IUs) Significant Industrial Users, (SIUs) and Categorical Industrial Users (CIUs).  These Wastewater Discharge Permits are valid for two (2) years and list certain requirements and conditions that must (required) be met in order to continue to discharge "Non-Domestic Wastewater", "Wastewater" and "Indirect Discharges or Discharge" (herein referred to as"Regulated Process Wastewater" from Commercial - Industrial facility into the City Sewer Collection System and Cedar City Regional Wastewater Treatment Facility (CCRWTF).  These requirements include yet, are not limited to controlling the quality and characteristic of their Regulated Process Wastewater discharge by installing Best Available Treatment Technology (BATT) and/or additional regulatory oversight; to treat any volume, concentration/mass of Regulated Process Wastewater (and applicable Conventional/Priority and Local Limitation Pollutants) effluent prior to discharge into the City Sewer Collection System and CCRWTF.  Wastewater Discharge Permits require the Permitted Commercial - Industrial User to measure, sample and report to the CCRWTF Pretreatment Program  parameter Flow and additional Pollutants, (Conventional/Priority and Local Limitations) at a date/time and frequency/method.  Issuance of Wastewater Discharge Permits enables the requirement for subject Commercial - Industrial Users to enable additional Regulatory documents not limited to Spill and Slug Control Plans, (SSCPs) and Total Toxic Organic Management Plans, (TOMPs).


Zero-Discharge Permits:
Zero-Discharge Permits are issued to Industrial Users, (IUs) Significant Industrial Users, (SIUs) and Categorical Industrial Users (CIUs).  These Zero-Discharge Permits are valid for two (2) years and list certain requirements and conditions that prohibit the Permitted Commercial - Industrial User from discharging "Non-Domestic Wastewater", "Wastewater" and "Indirect Discharges or Discharge" (herein referred to as"Regulated Process Wastewater" from any connection within the Commercial - Industrial facility into the City Sewer Collection System and Cedar City Regional Wastewater Treatment Facility (CCRWTF).  Zero-Discharge Permits require the Permitted Commercial - Industrial User to report to the CCRWTF Pretreatment Program  parameter Flow and certify that any Evaporative System and/or Treatment Technology - Systems are operational and that no volume of Regulated Process Wastewater has discharged from subject Commercial - Industrial User facility and entered the City Sewer Collection System and CCRWTF.  Issuance of Zero-Discharge Permits enables the requirement for subject Commercial - Industrial Users to enable additional Regulatory documents not limited to Spill and Slug Control Plans, (SSCPs) and Total Toxic Organic Management Plans, (TOMPs).


Significant Industrial Users (SIUs) and Categorical Industrial Users (CIUs) Shall be Defined by the Following Criteria:

  • All Commercial - Industrial Users subject to Federal Categorical Pretreatment Standards under 40 CFR 403.6 and 40 CFR Chapter I, Subchapter N; and
  • Any Commercial - Industrial User that discharges an average of 25,000 gallons or more a day of Regulated Process Wastewater into the City Sewer Collection System and CCRWTF, (excluding Sanitary, Non-Contact Cooling and Boiler Blowdown Wastewater),
  • Any Commercial - Industrial User that contributes a Regulated Process Wastewater waste-stream which comprises 5 percent or more of the average dry weather hydraulic or organic capacity of the CCRWTF, 
  • Any Commercial - Industrial User designated as such by the CCRWTF Pretreatment Program on the basis that the Commercial - Industrial User has a reasonable potential for adversely affecting the CCRWTF operation(s) or for violating any Pretreatment Standard or Requirement (reference 40 CFR 403.8 (f)(6)).
  • The CCRWTF PRetreatment Program may determine that an Commercial - Industrial User subject to Categorical Pretreatment Standards under 40 CFR 403.6 and 40 CFR chapter I, Subchapter N; is a Non-Significant Categorical Industrial User (NSCIU) rather than a Significant Industrial User (SIU) on a finding that the Commercial - Industrial User never discharges more than 100 gallons per day (GPD) of total Categorical -Regulated Process Wastewater (excluding Sanitary, Non-Contact Cooling and Boiler Blowdown wastewater, unless specifically included in the Pretreatment Standard) and the following conditions are met:

  • (i) The Commercial - Industrial User, prior to the CCRWTF Pretreatment Program's finding, has consistently complied with all applicable Categorical Pretreatment Standards and Requirements;
  • (ii) The Commercial - Industrial User annually submits the certification statement required in 40 CFR 403.12(q) together with any additional information necessary to support the certification statement; and
    (iii) The Commercial - Industrial User never discharges any untreated concentrated wastewater.

  • (3) Upon the CCRWTF PRetreatment Program finding that a Commercial - Industrial User meets the criteria in paragraph (v)(1)(ii) of this 40 CFR section, (and a determination has been made that subject Comemrcial - Industrial User has no reasonable potential for adversely affecting the CCRWTF operation or for violating any Pretreatment Standards or Requirement, the CCRWTF PRetreatment Program may at any time, on its own initiative or in response to a petition received from a Commercial - Industrial User or Publicly Owned Treatment Works (POTW), and in accordance with 40 CFR 403.8(f)(6), determine that such Commercial - Industrial User is not a Significant Industrial User (SIU).
