What is 310?
Montana’s Natural Streambed and Land Preservation Act of 1975, commonly referred to as the 310 Law, requires that any person or entity proposing to work in or near a perennially-flowing stream on public on private land must first obtain a 310 permit from the local Conservation District. The purpose of the law is to minimize soil erosion and sedimentation, and to protect and preserve streams in their natural or existing state.
Visit Montana’s 310 permit process for more detailed information. Not sure what type of permit you need? Start with MT DNRC website. There is no charge for a 310 permit.
