Significant Industrial Users are required by the Code of Federal Regulations (40CFR Part 403) to have a wastewater discharge permit for their process effluent. Colorado Springs Utilities is the local control authority that issues wastewater discharge permits. Specific manufacturing, production and fabrication processes are regulated and will be permitted, inspected and monitored. New businesses to the Colorado Springs area with certain process activities must complete a questionnaire to help us determine the appropriate regulated category. The applicable federal category (see below) includes the maximum allowable discharge limits for the process wastewater discharge. Local limits also apply to the process effluent, contact the Industrial Pretreatment Section for a copy of the Wastewater Treatment Code. An updated permit application must be completed annually by each permitted industry to assure that all changes and additions to the regulated processes are reported. Permitted industries must perform sampling and analysis of the process effluent. Chemical analyses must be performed by EPA approved methods and the monitoring results will be sent to the Industrial Pretreatment Section. Parameters to be analyzed are outlined in the wastewater discharge permit. For a copy of a self-monitoring report based on gallons per day of process wastewater effluent, please choose from the following: 0-10,000 gpd
10,001-50,000 gpd
>50,000 gpd
