It is expected that the State of Maine multi-sector general stormwater permit for industrial facilities will be signed by Commissioner Mercer shortly. The new 5-year permit requires that facilities subject to the permit, file a notice of intent to be covered within 60 days. The notice of intent requires that the permittee have and implement a stormwater pollution prevention plan that meets permit requirements.

The permit appears to be substantially similar to the prior multi-sector general permit issued in 2011, although minor changes have been made to various sectors. As a result, you should carefully review the new permit to make sure that either a general provision or your sector-specific requirements have not changed.
