SB 391 Montana Senate · 2025 Regular Session

Revise opencut notification laws

SB 391 would revise Montana's rules for public notice and participation in open-pit mining permit applications. It requires the Department of Environmental Quality to formally respond to public comments on permit applications and updates definitions related to mining operations. This directly affects mining operators seeking permits, nearby residents (especially those within ½ mile of proposed sites), and landowners whose property may be impacted. The bill aims to strengthen public engagement by ensuring written responses to community concerns before permits are issued.
