Environmental Services provides technical support to the utility, ensuring compliance with all regulatory mandates and permits. This includes the operation of the wastewater laboratory, management of the industrial pretreatment program, and implementation of the Fats, Oils and Grease (FOG) program.
The wastewater laboratory continuously monitors the treatment process and helps to optimize the operation of the plants. The Pretreatment program is responsible for maintaining close scrutiny of major industrial customers to ensure that their discharge is within permitted limits. The FOG program works closely with all food service establishments to minimize the amount of fats, oils, and grease that enter into the wastewater collection system, which can result in blocked sewer lines and sewer spills.
SRU Industrial Pretreatment Program
The City’s Pretreatment Program is a State and EPA mandated program. The Pretreatment Program is designed to protect the sewer
collection system, wastewater treatment plants and their receiving streams, as well as SRU employees. The Program’s authority and all pretreatment requirements can be found in the City of Salisbury’s Sewer Use Ordinance (SUO).
Industries that are connected to the sanitary sewer and discharge process wastewater may be required to have an industrial discharge permit based on the criteria for Significant Industrial Users as outlined in Chapter 25-1 of the Code of the City of Salisbury, their SIC code, federal categorical standards, as well as the volume and/or concentration of wastewater discharged to the sanitary sewer.
Industries that are permitted are given permit limits based on state, federal, and local limits found in the SUO as well as allocation tables prepared for each wastewater treatment plant. The Pretreatment Program currently has eight (8) Significant Industrial Users permitted and two (2) local industries permitted. All requirements of the City’s Pretreatment Program are implemented by the Pretreatment Program Coordinator and Regulatory Compliance Technician.
