Phase I/II

In 2005, U.S. EPA established formal requirements for All Appropriate Inquiry (AAI), a process used in establishing the innocent landowner defense under Superfund. These requirements, which are reflected in the revised ASTM E1527-13 standard of practice, place greater emphasis on the qualifications of environmental professionals who perform Phase I ESAs. The 2013 revisions to the ASTM standard include updated definitions of recognized environmental conditions, clarifications of user responsibilities and file review requirements, and inclusion of vapor migration as a contaminant pathway. We at TriAD are pleased that the industry standards of practice formally recognize the vital importance of experience and qualifications in performing this type of work.

If recognized environmental conditions are identified, TriAD’s professionals can target suspect areas for additional investigation, including sampling of worst-case areas to determine whether contamination exists at concentrations of concern. With the data from the Phase II investigation in hand, we can assist as needed in negotiating a brownfields agreement with the existing owner and state regulators to ensure that the purchaser obtains needed liability protection from future investigation and remedial action.

TriAD has provided many clients with high-quality due diligence that is the keystone to the innocent landowner defense. From small, urban lots to large industrial complexes, we work hard to provide the data needed to make informed decisions about property acquisitions. TriAD professionals have performed Phase I investigations in over 20 states for clientele ranging from individuals to multi-national corporations.
