This bill appropriates $6,229,375 from the historic preservation grant program account to the Department of Commerce for various historic preservation projects during the biennium starting July 1, 2025. It outlines a list of authorized projects and their respective grant amounts, with specific conditions for grant disbursement. Notably, the bill amends Section 4(1) of Chapter 710, Laws of 2023, to update the appropriations for certain projects, including the replacement of the original Montana Club Cooperative Association with Rathskeller, LLC, and the removal of the Rocky Mountain Building project.

Additionally, the bill establishes conditions that grant recipients must meet to receive funding, such as documenting matching funds, having an approved project management plan, and complying with auditing requirements. It also specifies that if project costs exceed the grant amount, the recipient is responsible for the overage, and no supplemental appropriations will be granted. The bill is set to take effect on July 1, 2025, and includes provisions for notifying tribal governments about the appropriations.
