House Bill 1827 amends Tennessee Code Annotated to require local government approval for the establishment of quarries and digital asset mining facilities. Specifically, it mandates that the appropriate local legislative body must hold a public meeting to approve the location of such facilities before they can be constructed. The bill stipulates that at least twenty-one days' notice must be provided for the meeting, which includes publication in a local newspaper, posting on the local legislative body's website, and notifications to residents within 500 yards of the proposed site.

The bill defines a "digital asset mining facility" as a site with computers consuming over one megawatt of energy for blockchain protocol security, and a "quarry" as the extraction and processing of various minerals, excluding coal and deep metal mining. This legislation is set to take effect on July 1, 2026, and will apply to any proposed facilities constructed on or after that date.
