The “Three-Acre General Permit”

In addition to adopting a new rule, the DEC was required to adopt a general permit for stormwater from so-called “three-acre sites” -existing sites with three or more acres of impervious surface that lack a stormwater permit based on the 2002 Stormwater Management Manual. Once the Ch. 22 Stormwater Permitting Rule was finalized, the DEC adopted General Permit 3-9050, which went into effect on December 1, 2020. The Ch. 22 Stormwater Permitting Rule includes standards applicable to this general permit, as well as all stormwater permitting.

DEC’s Stormwater Program welcomes your input on the Ch. 22 Stormwater Permitting Rule and General Permit 3-9050. Questions or comments should be directed to Kevin Burke, Stormwater Program Manager, at kevin.burke@vermont.gov or (802) 261-7903.
