DEQ Seeks Public Comment on Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activity
HELENA—The Department of Environmental Quality is proposing to renew the Montana Pollutant Discharge Elimination System Multi-Sector General Permit (MSGP) for stormwater discharges associated with industrial activity such as mining. The renewal of the multi-sector general permit will continue to provide statewide general permit coverage for owner and operators of industrial activities that discharge stormwater to state surface waters.
The general permit requires permittees to develop, implement, and maintain a Stormwater Pollution Prevention Plan that includes best management practices designed to manage and treat stormwater. The permit is renewed every five years. In this renewal, DEQ has proposed new requirements for permittees to post a public sign near the facility entrance, and for any industrial subsector with no existing monitoring requirements to conduct monitoring and report the results to DEQ.
The current multi-sector general permit expires Jan. 31, 2023 and the renewed general permit will be issued by July of 2023 and effective Feb. 1, 2023.
A public hearing will be held to provide a brief presentation on the new requirements and accept comment on the general permit and associated environmental assessment.
What: A public hearing on the multi-sector general permit for stormwater discharges.
When: Feb. 24, 2022 at 10 a.m.
Where: The meeting will be held at DEQ Headquarters in Room 111 (1520 E. 6th Avenue in Helena, Montana) and online or by telephone. For more information visit: https://deq.mt.gov/News/publiccomment-folder/news-article53
