Phase I ESA

Phase I Environmental Site Assessment: Connecticut & New York


There are numerous risks involved with purchasing a commercial, industrial or agricultural property.  One that can be costly is dealing with hazardous waste contamination discovered on property you have recently acquired. Performing an environmental site assessment prior to acquiring a property can minimize that risk.


A Phase I ESA involves a review of state and local records, a site inspection, and interviews with owners,occupants, neighbors and local government agencies. Sub-surface sampling and laboratory analysis are typically not included in this phase.


Contamination can result from activities that took place on the site. Contamination could also come from activities at a nearby property. The records and interviews will be the best sources to provide this information. Public records are available regarding the locations of properties that have been classified as contaminated by federal or state regulations. Depending on their proximity to your site, contamination could have made its way to your site.


Standards for the Phase I and Phase II ESAs have been established by the American Society for Testing and Materials (ASTM) to address the “All‐Appropriate‐Inquiry” (AAI) aspect to the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). CERCLA contains national policy and procedures for containing or removing hazardous substances that have been released, and also provides funding and guidance for cleaning up some abandoned and contaminated hazardous waste sites. Be aware of state, local, or federal regulations outside of CERCLA that have other site assessment requirements and liability protections.
