Pretreatment

The pretreatment program is designed to keep the waste from commercial entities under control with regards to fats, oils and grease that flows down the drains.

The City of Port Arthur Wastewater Pretreatment Program ensures that local, state and federal regulations are met regarding the quality of wastewater discharged into the City’s wastewater system. Our main job is to protect the Publicly Owned Treatment Works (POTW), also known as the wastewater treatment plant that controls discharge from commercial and industrial users (IU). Port Arthur area businesses are required to install, operate and adequately maintain pretreatment devices and/or systems to remove pollutants that could otherwise damage or obstruct the wastewater collection system or interfere with the wastewater treatment process.

Some major elements of the City's Pretreatment Program include reviewing pretreatment designs, issuing permits, performing inspections, collecting samples, reviewing self-monitoring reports, and enforcing regulations. We are also dedicated to reaching beyond the traditional “command and control strategy” by working with our local community to share our expertise and facilitate pollution prevention.

Pretreatment is the term used to describe what industries may have to do to their waste stream prior to discharge to the City’s collection system and POTW. It is often easier to treat a waste at its source than it is after it has traveled down the line or entered the wastewater plant. Pretreatment requirements also help to insure that industrial users pay a fair portion of the costs for their particular contribution to the overall waste stream.

The following criteria will cause an IU to be included in a local Program:
• An industry categorized as a Significant Industrial User (SIU) or a Categorical Industrial Users (CIU), as specified in 40 CFR (Code of Federal Regulations) 403.6 and Parts 405-471.
• An IU discharging 25,000 gallons per day or more of process wastewater, noncontact cooling water, or boiler blowdown.
• An IU which contributes 5% or more of the dry-weather hydraulic loading or capacity of POTW.
• Any IU having reasonable potential to adversely affect the POTW, or who violates any standard or requirement.

The main function of the Pretreatment Program is to protect the POTW by consistently tracking the output of wastewater from Industrial Users. There are two regulations that govern pretreatment programs: 40 CFR, Parts 122 and 403.
