Remediation Projects Funded by the Abandoned Mine Lands Unit

The Abandoned Mine Lands Unit (AMLU) began funding abandoned mine remediation projects on California’s public lands in 2002 and has now remediated more than 600 hazardous mine features.  Methods used include: bat-compatible gates, cupolas, and culverts; polyurethane foam (PUF); backfills; wire fences; capping; and removal of hazardous debris. 

Since January 2006, the AMLU’s primary funding to remediate physical hazards at abandoned mine sites has come from a fee collected on gold and silver mined in California ($5 per ounce of gold and 10¢ per ounce of silver; see Public Resources Code § 2207(d)(4)(B)).  By working with land-owning agencies that contribute funds or in-kind services and other partners, the AMLU has leveraged State dollars by nearly 100%, remediating more hazards than it could with its own resources only.
