Using Site Pollution Liability Insurance to Close Real Estate Deals

Today’s site pollution liability insurance is a useful tool that both buyers and sellers can use to help efficiently close real estate transactions involving environmental risk.

For example, a property buyer may more easily secure a loan by naming their lender as additional insured on a policy through a “mortgagee insured endorsement,” reducing the lender’s risk and hesitation. Owners of commercial real estate can purchase the insurance to remove a potential environmental liability from its balance sheet, satisfying shareholders’ and directors’ requirements. A property seller can buy a site pollution liability insurance policy and name the buyer as an insured, preserving the sales price during negotiations.Learn more. Hylant. Environmental Risk.

In the past, few carriers offered site pollution liability insurance. Today, there is abundant market competition and capacity with at least 20 programs competing in site pollution for portfolios and transactions, including 10 receptive to sites with a history of pre-existing conditions. Policies generally address cleanup (remediation) and claims for bodily injury and property damage, including legal defense costs. Coverage is a combination of first-party protection (e.g., money to clean up contamination on your site) and third-party remedy (e.g., a spill on your site has migrated to your neighbor’s property).

Environmental Due Diligence Considerations

As insurance carriers review sites and consider policy language, site investigations and other due diligence reports play an important role. A well-delineated site will likely gain coverage considerations that an unexplored location will not.
Carriers consider coverage for existing conditions, which are pollution releases occurring before the policy inception date, and new conditions, for pollution releases occurring after the policy inception date. When considering existing issues, they focus on how they might address known conditions (identified as part of due diligence) and unknown conditions (something missed during site investigations). Policies are bound for up to a 10-year duration, adding reassurance to backstop the deal.

Most large claims for cleanup coverage have been the result of unknown pollution discovery. Another type of unknown condition is “emerging contaminants.” These aren’t conditions missed during site investigations; rather, they are conditions that had not yet been identified as concerns when the site due diligence took place.

The Challenge of Emerging Contaminants

Perfluoroalkyl and polyfluoroalkyl substances, commonly called “PFAS” in the news, are prime examples of emerging contaminants. These chemicals, omnipresent in manufacturing from the 1940s until they were phased out in the early 2000s, were frequently discharged into public waterways and have contaminated large regions of groundwater. It is only because of our increased ability to detect, measure, test and analyze compounds in the environment more precisely and in smaller concentrations that we now know that some of these chemicals bioaccumulate, posing human health risks.

In 2016, the U.S. Environmental Protection Agency (EPA) issued PFAS-related drinking water health advisories, setting the safe allowable chemical limit at 70 parts per trillion. There is growing pressure to further regulate PFAS under the Safe Drinking Water Act. Many states are currently evaluating and setting even lower limits, with some legislators proposing limits as low as five parts per trillion. The U.S. House of Representatives recently introduced bipartisan legislation to classify PFAS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (i.e., CERCLA or Superfund). The PFAS Action Act of 2019 would require the EPA within one year to designate all PFAS compounds as hazardous substances under the Superfund law, paving the way for the U.S. government to sue PRPs to recover cleanup costs. Current remedial technologies are costly, and alternative remedies for site contamination have not yet been extensively studied. Regardless, PFAS contamination is expected to remain difficult and expensive to remediate.

As science progresses, we will detect and see other commonly used chemicals correlate with human health problems and the degradation of natural resources, making them subject to future regulation and likely leading to exposure for claims related to remediation, bodily injury and property damage. Nanomaterials and nutrient pollution (in the form of algal blooms) are just two examples of substances under increasing scrutiny and emerging concern. Owners, operators and buyers of real estate should be aware that advances in analytical technology and in substance and disease correlation could subject them to future liability.

Site pollution liability insurance can help both property buyers and sellers manage their risks when transacting deals. This coverage is complex and subject to appetite change as new pollutants emerge and regulations are revisited. Those involved in these transactions should work closely with an insurance brokerage offering a dedicated environmental practice and deep experience with negotiating coverage for these types of exposures.
