Demonstrating that the recent announcement of new stormwater controls for the Charles River in Massachusetts were not an aberration, EPA, joining with the Maine DEP, announced last Friday that it will be imposing new stormwater regulations for discharges into Long Creek, which ultimately flows into Casco Bay.
Responding to petitions from the Conservation Law Foundation, EPA has exercised its Residual Designation Authority under its NPDES permitting regulations.
The new designation can be found on EPA’s website. Notably, the new program will apply to impervious surfaces larger than one acre. This is a smaller area than is currently proposed for the Charles River. EPA estimates that regulating impervious surfaces one acre and up will place 90% of all impervious area in the Long Creek watershed under NPDES jurisdiction.
Owners of properties in other degraded watersheds, you may be next on the list.
