You asked if state law compels a town or a known property owner to address a local blight on, or potential contamination of, the property.

STATE LAW AND BLIGHT

State law does not appear to require a town or known property owner to address blight issues or potential contamination on a property. By law, towns can adopt and enforce anti-blight ordinances and fine owners for violating them (CGS § 7-148 (c) (7) (H)). But the town would have to enforce such ordinances. Alternatively, either the town or its residents could write to the Department of Environmental (DEP) commissioner to report suspected contamination or specific knowledge of a spill that would have required the responsible party to notify the state, according to Tom Tyler, DEP Legislative Liaison. The DEP would consider the report and could inspect the property, which could lead to remediation of the property, if it were found to be contaminated.
