After completion of such project, the municipality may use the property for public purposes or may dispose of it. If the municipality shall dispose of such property by sale to a responsible party, such party shall pay to such municipality, in addition to such other consideration, an amount of money constituting the amount of state assistance provided under this title plus accrued interest and transaction costs and the municipality shall deposit that money into the environmental restoration project account of the hazardous waste remedial fund established under section ninety-seven-b of the state finance law. 5. In the event that an environmental restoration project's remediation objective shall not have been attained to the department's satisfaction at the time of the municipality's disposition of such property, such municipality shall be liable to ensure that such objective is attained within the time called for in the state assistance contract.
