Environmental Lien

Understanding Environmental Lien

Environmental liens arise from federal and state environmental laws, most notably CERCLA (the Superfund law), which allows the government to clean up contaminated properties and recover costs from current and former owners. These liens secure the government's right to repayment of cleanup costs and provide notice to future purchasers of environmental issues.

Environmental contamination can come from many sources: former gas stations, dry cleaners, industrial operations, underground storage tanks, illegal dumping, agricultural chemicals, and lead paint. The costs of remediation can range from tens of thousands to millions of dollars, often exceeding the property's value.

For tax delinquent property investors, environmental liens represent one of the most dangerous hidden risks. A property may be tax delinquent precisely because the owner learned of contamination and abandoned it rather than face cleanup costs. Environmental liability can follow the property to new owners—including tax sale purchasers.

Due diligence for environmental issues goes beyond checking for recorded liens. Investors should research the property's historical use through Sanborn fire insurance maps, historical aerial photographs, and EPA databases. A Phase I Environmental Site Assessment (ESA) identifies potential contamination risks, while a Phase II ESA involves actual testing of soil and groundwater.

Some states offer protections for innocent purchasers who acquire contaminated property without knowledge of the contamination, but these protections require conducting appropriate due diligence before purchase. Skipping environmental due diligence can expose investors to unlimited liability.
