Generally revise Montana environmental policy act

HB 285 revises the Montana Environmental Policy Act (MEPA), clarifying its purpose and impact on state agency actions and permitting decisions. The bill specifies that MEPA is a procedural law designed to provide information to the public and decision-makers, not to grant additional regulatory authority to state agencies. It also shifts the burden of proof for those challenging licensing or permitting decisions, requiring them to establish the unconstitutionality of the underlying statute. Furthermore, legal challenges must now be filed in the county where the proposed activity is located.
