General Permit 3-9050 is a permit for stormwater runoff from impervious surfaces. It is an important component of the Vermont Clean Water Act of 2015 (Act 64) and is designed to assist in the implementation of clean-up efforts in Lake Champlain, Lake Memphremagog, and stormwater-impaired waters, while also protecting high quality surface waters statewide. The permit was issued on September 1, 2020, and goes into effect on December 1, 2020.

Therefore, the last day to apply under General Permit 3-9010 or General Permit 3-9015 is Monday, November 30, 2020.

The Department of Environmental Conservation must receive applications for coverage under these general permits by then in order to be valid. Any valid (unexpired) authorizations previously issued under these general permits remain in full force and effect until the expiration of the authorization. 

All applications for an operational stormwater permit for new development, redevelopment, permit renewal, or for “three-acre sites” received on or after December 1 must be under General Permit 3-9050. DEC is in the process of updating its website and application forms. Although they hope to have the 3-9050 Notice of Intent forms available by December 1, there may be some delays.

If you have any questions concerning General Permit 3-9050 and its applicability to any of your projects please contact the Stormwater Program staff for the region in which your project is located.
