Electronic Reporting for Water Quality Permits

For several years, National Pollutant Discharge Elimination System, or NPDES, individual permit holders have been submitting discharge monitor report data electronically through the U.S. Environmental Protection Agency's NetDMR program, while NPDES general permit registrants, WPCF individual permit holders, and WPCF general permit registrants submit their DMRs on paper to the Oregon Department of Environmental Quality.

EPA's Electronic Reporting Rule modernizes reporting for municipalities, industries and other facilities that hold NPDES permits. The rule requires NPDES permit holders to report information electronically instead of filing written paper reports. The rule does not change what information is required, it only changes the method by which information is provided. 

DEQ may grant a waiver that allows a permitted facility to submit physical reports to meet requirements of its NPDES permit.
