Federal and State Regulations require that the City maintain an industrial pretreatment program that is designed to work with industrial and commercial customers who meet certain criteria.
The intent of the pretreatment program is to protect the sewer system and wastewater treatment plant from pollutants that may be discharged into the sewer system by local industries. These pollutants may have the potential to upset the wastewater treatment plant and cause pollutants to pass through the plant untreated, or partially treated, and then be discharged to the Penobscot River. This program is also designed to protect sewer systems and plant personnel by controlling and, in some cases, prohibiting the discharge of dangerous wastewater into the sewer system. The United States Environmental Protection Agency recognized the City's Industrial Pretreatment Program as one of the best in the country in 2002.
Please remember that compliance with all Federal, State, and Local regulations is the responsibility of the user and that proper notification and permits must be secured prior to start-up!
