Water Quality - Permits

Welcome to the Permits Section

We issue legally binding permits for the discharge of pollutants to state waters, including surface waters and some groundwater.

Our job is to ensure that the discharge permits we issue protect the beneficial uses of those waters (domestic water supply, aquatic life, agriculture, recreation, and wetlands.)

Clean water permitting sectors (permits by category)

Our clean water permit sectors page provides information about commerce and industry, construction, municipal separate storm sewer systems (MS4), domestic sewage systems, biosolids, pesticides, reclaimed water, pretreatment, and contacts.

Basin schedule for individual permits

Individual process water permits to surface water are renewed under a basin schedule. Each year, the Water Quality Control Commission holds a basin hearing in June, which becomes effective in December. The Permits Section starts renewing permits in the basin the year after the Commission hearing.

The division does not currently have the resources to renew all permits every time it works in a basin. The division uses this criteria to prioritize individual permit renewals. When the division is working in a basin, it regularly shares its progress during the quarterly Clean Water webinars.
