Allows counties and municipalities to use open space trust funds for remediation of collapsed mine shafts and sinkholes on property owned by county or municipality.

This bill would allow New Jersey counties and municipalities to use funds from their existing open space trust funds to remediate collapsed mine shafts and sinkholes on public property. Currently, these funds are used for open space, recreation, floodplain protection, farmland, and historic preservation purposes. The bill expands the authorized uses to include mine shaft and sinkhole remediation, requiring local governments to adopt an ordinance and hold a public hearing before using funds for this purpose. There's a $100,000 limit per project, and funds would be moved to a new "Mine Remediation Trust Fund" for this specific purpose.
