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 their existing open space trust funds for repairing collapsed mine shafts and sinkholes on land they own. Currently, these funds can only be used for open space, recreation, floodplain protection, farmland, and historic preservation projects. The bill requires counties and municipalities to hold public hearings and provide notice before using funds for this purpose, with a $100,000 spending limit per project. It expands the authorized uses of these trust funds without requiring new voter approval, but mandates additional transparency through public notice and hearings. This change directly affects local governments with mine-related hazards on their property, providing a new funding mechanism for addressing these safety concerns.
