Wastewater Permits Program

​MDE’s Wastewater Pollution Prevention and Reclamation Program (WWPPRP), within the Water Management Administration, issues permits to protect Maryland’s water resources by controlling industrial and municipal wastewater discharges. Surface water discharges are regulated through combined State and federal permits under the National Pollutant Discharge Elimination System (NPDES). Groundwater discharges are regulated through State issued groundwater discharge permits. Also related to the protection of groundwater is the WWPPR​P coordination with all local health departments for the regulation of individual wells and septic systems.

Important Announcement - Electronic Reporting Rule 

On December 21, 2015, the U.S. Environmental Protection Agency promulgated a final rule to modernize Clean Water Act reporting for municipalities, industries, and other facilities by converting to an electronic data reporting system (40 CFR 127.16). The final rule requires all National Pollution Discharge Elimination System (NPDES) regulated entities to electronically submit Discharge Monitoring Reports (DMRs) starting on December 21, 2016. Before you can submit official DMRs online using NetDMR, you must attend a training webinar, successfully complete account set-up, and submit example monitoring results electronically.

The NetDMR website is located at https://netdmr.epa.gov and technical support is available at https://netdmr.zendesk.com/home. An application form for a waiver from electronic reporting requirements can be found here. Applications for a waiver from electronic reporting requirements must be submitted to the Department for written approval by August 23, 2016 (120 days in advance of the December 21, 2016 deadline). A brochure with additional information, including contacts, can be found here​.
