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 allows New Jersey counties and municipalities to use open space trust funds to repair collapsed mine shafts and sinkholes on land they own. It amends existing state law to expand the purposes for which these funds can be spent, specifically adding mine remediation to the list of authorized uses. The legislation applies to local governments that have already approved trust funds through voter initiatives for open space, recreation, and related conservation purposes. By making this change, the bill provides local governments with a legal mechanism to address environmental hazards caused by abandoned mines using existing public funds.
