HB 923
Montana law revised to expand categorical exclusions from water quality nondegradation requirements, reducing regulatory review for certain development activities.
HB 923 modifies Montana's water quality nondegradation standards by revising which categories of activities are exempt from requiring nondegradation authorization. The bill adjusts the categorical exclusions that allow certain projects to proceed without demonstrating they won't degrade water quality beyond existing standards.
Nondegradation standards protect existing water quality by requiring developers and industries to prove their projects won't harm it. Changes to categorical exclusions directly affect which projects face regulatory scrutiny, potentially accelerating some development while altering environmental oversight in Montana's water resources.
