Good Samaritan Remediation of Abandoned Hardrock Mines Act of 2023

This bill promotes the remediation of abandoned hardrock mine sites by Good Samaritans. A Good Samaritan means a person that is (1) not a past or current owner or operator of the abandoned site; (2) had no role in the creation of the historic mine residue; and (3) is not potentially liable under any law for the remediation, treatment, or control of the historic mine residue.

The bill requires the Environmental Protection Agency (EPA) to establish a Good Samaritan pilot program. Under the program, the EPA may issue permits to allow Good Samaritans to remediate historic mine residue at abandoned hardrock mine sites without being subject to enforcement or liability under specified environmental laws for past, present, or future releases, threats of releases, or discharges of hazardous substances or other contaminants at or from the abandoned mine site.

In addition, the bill establishes a Good Samaritan Mine Remediation Fund for land management agencies that authorize Good Samaritans to conduct remediation projects on federal land.
