Stormwater Updates: Expanding Regulation to Half Acre, Redrafting Stormwater Management Manual

As you might be aware, the Department of Environmental Conservation is proposing to lower the threshold for requiring a stormwater permit from one acre to half an acre in the following cases: (1) construction or redevelopment of impervious surface of one half acre or more and (2) expanding an existing impervious surface by more than 5,000 square feet if the total resulting area is greater than one half acre.

The House Fish, Wildlife, and Water Resources this week will consider draft language to make these statutory changes, as well as to automatically change existing rules for one acre or more now apply to one half acre or more. However, as drafted the changes would not come into effect until “the effective date of the next amendments to the Stormwater Management Manual” (see below). The language might be attached to a different bill already in Committee.

Additional information and analysis will be provided in upcoming posts. In the meantime, members are encouraged to contact us with any questions or recommendations, and to let us know if you are interested in engaging on this proposal should it move forward.
