Pretreatment Program

Program Ordinance

The City of Frederick’s Department of Public Works implemented an Industrial Pretreatment Program in 1986, which was approved by the Maryland Department of the Environment and the U.S. Environmental Protection Agency. The city’s Industrial Pretreatment Program regulates non-residential users of the city’s Publicly Owned Treatment Works (POTW) by administering and enforcing the city’s Industrial Pretreatment Ordinance.

The primary objectives of the Ordinance are:

  • To ensure the health, safety, and welfare of the public and the environment
  • To protect the life, health, and safety of city operating and maintenance personnel
  • To protect the POTW from the introduction of pollutants that might interfere with its operation or pass-through the city’s wastewater treatment plant untreated causing harm to the Monocacy River
  • To provide the opportunity for beneficial reuse of biosoilds


To ensure non-residential users are in compliance with federal, state, and local discharge requirements, the city’s Pretreatment Program issues wastewater discharge permits, conducts sampling, and monitoring of industrial user’s wastewater discharge and performs inspections of industrial users’ facilities.
