Goals of the Pretreatment Program

  • Prevent the introduction of pollutants into the wastewater treatment plant that will interfere with treatment operations
  • Prevent the introduction of pollutants into those plants that will pass through the treatment process and be incompatible with the environment
  • Improve the feasibility of reclaiming the municipal and industrial wastewater, and biosolids (sludge) for land application
  • Provide for the fair and reasonably equitable distribution of all costs associated with operation of wastewater collection and treatment systems

Frederick County Business Sewer Users

New, relocating or expanding businesses which are connected or planning to connect to the Frederick County sewer system are required under the Frederick County’s Industrial Wastewater Pretreatment Ordinance to provide specific information by completing an Industrial Waste Survey.

Commercial Sewer Users

Commercial sewer users with only hand washing and toilet facilities need to complete Section I and II of the Industrial Waste Survey and sign the Certification Statement. Sections II through VII may not apply to all applicants and should be completed only if so directed.

Any commercial sewer user discharging wastewater other than hand washing and toilet flushing may need to submit the following documents in addition to the Industrial Waste Survey:

Additional information concerning the Industrial Pretreatment Program can be found in the Pretreatment FAQ. 

Dental Amalgam

Amalgam contains mercury.  Mercury is a potent neurotoxin that bioaccumulates in fish and shellfish and ultimately affects human health and the environment.

Federal Rule

The United States Environmental Protection Agency (USEPA) has set a national               standard that will reduce the discharge of mercury containing dental amalgam from                 dental practices to sewer plants.  The standard includes mandatory use of amalgam             separators or similar devices, and Best Management Practices (BMP's) endorsed by the       American Dental Association (ADA). 

Dental Practice Responsibilities

 Depending on your specific practice, different requirements and deadlines must be   achieved.

Pretreatment Program

The Pretreatment Program provides for the regulation of wastewater discharges into the sanitary sewer system. The department administers the program in accordance with the Frederick County Industrial Waste Ordinance 12-33-628.
