Industrial Pretreatment Program
The primary focus of the City of Boulder's Industrial Pretreatment Program is to reduce the amount of toxic and hazardous waste that enters Boulder's wastewater utility.
By pre-treating their waste, Boulder industries can help reduce the amount of pollutants that are discharged to the city's wastewater utility.
The goals of the Industrial Pretreatment Program are to:
- promote the general health, safety and welfare of all who use Boulder's wastewater system;
- protect city personnel who work with wastewater and biosolids;
- prevent pollutants from entering the wastewater treatment system;
- minimize pollutants that may interfere with the operation of the wastewater treatment system;
- maximize opportunities to recycle and reclaim wastewaters and biosolids from the system;
- distribute costs for the wastewater utility equally among Boulder customers; and
- prevent the introduction of wastes that may adversely affect the environment or cause a violation of the city's National Pollution Discharge Elimination System (NPDES) permit, which is issued by the Colorado Department of Public Health and Environment.
The Industrial Pretreatment Program is located at the city's wastewater treatment facility.
Certain types of industrial and commercial industries with the potential to discharge pollutants are regulated through an industrial discharge permit system. A discharge permit is required for significant industrial users. Businesses are considered as significant industrial users if they:
- Discharge an average of 25,000 gallons or more of processed wastewater per day;
- Have the potential to adversely affect the city's wastewater utility; or
- Are categorical users subject to the Environmental Protection Agency's Categorical Pretreatment Standards (categorical users, such as metal finishers and pharmaceutical manufacturers, receive increased scrutiny due to their potential to pollute).
Permitted industries must pay an annual permit fee, monitor their wastewater discharges on a routine basis, submit to city monitoring and inspections, and develop a spill control plan for their facility.
