SB 221 Montana Senate · 2025 Regular Session

Generally revise the Montana environmental policy act

SB 221 revises the Montana Environmental Policy Act (MEPA) by establishing new requirements for greenhouse gas (GHG) assessments during state agency environmental reviews. Under this bill, state agencies are mandated to conduct GHG assessments for proposed actions classified as "fossil fuel activities." For other proposed actions, agencies may conduct a GHG assessment if deemed necessary for MEPA compliance. The bill clarifies that these assessments are for informational purposes, and state agencies cannot regulate greenhouse gas emissions or deny permits based solely on these GHG assessments under MEPA. This affects Montana state agencies conducting environmental reviews and entities proposing fossil fuel-related projects.

MODERATE
This bill clarifies how Montana's environmental review process handles greenhouse gas emissions following court rulings that limited the Department of Environmental Quality's authority to regulate them. The legislation establishes a requirement for agencies to conduct greenhouse gas assessments for fossil fuel projects while explicitly stating that greenhouse gases will not be regulated through permits.
Scope change
The bill expands the scope of environmental reviews to specifically require greenhouse gas assessments for fossil fuel activities, while simultaneously removing the authority to deny permits based on greenhouse gas emissions.
REQUIREMENT

Requires state agencies to conduct greenhouse gas assessments for proposed actions defined as fossil fuel activities under existing law.

DEFINITION

Clarifies that greenhouse gas assessments are intended to satisfy informational requirements under the Environmental Policy Act without creating regulatory authority over emissions.

ENFORCEMENT

Removes the ability of agencies to withhold, deny, or impose conditions on permits based solely on greenhouse gas emissions analysis.

SCOPE

Adds explicit legislative intent that greenhouse gas analysis should be conducted for fossil fuel projects to ensure public information about impacts.
