Site Assessments – Phase 1 Overview
Our staff has completed Phase 1 ESAs in Virginia, North Carolina, Connecticut, Maryland, Pennsylvania, New Jersey, New York, Kentucky, and Texas.
The diversity of our private sector clients and complexity of the subsurface conditions encountered at each site, has increased our knowledge of the technical, financial, and legal aspects to be considered for each new project in order to protect the best interests of our client.
The completion of an environmental assessment prior to the purchase of property is precipitated by the Superfund Amendments and Reauthorization Act (SARA) of 1986. Under the 2002 Small Business Liability and Brownfields Revitalization Act, Congress ordered the U.S. EPA to codify the first federal environmental site assessment rule in history to address each of ten steps that must be satisfied prior to a property purchase to qualify a landowner for liability protection under CERCLA.
Effective November 1, 2006, a property purchaser must comply with either the federal rule entitled “Standards and Practices for All Appropriate Inquiries” (40 CFR Part 312) or ASTM’s revised Phase I environmental site assessment standard (ASTM E 1527-21) to qualify as an innocent landowner, contiguous property owner or bona fide prospective purchaser under CERCLA. In 2008, American Society for Testing and Materials (ASTM) also published guidance on vapor intrusion issues impacting site assessments.
Our staff periodically reviews guidelines published by various national professional associations for the most current definitions of ‘all appropriate inquiry’ and incorporates that information into subsequent site assessments. Currently we rely on ASTM E 1527-21 standard to perform Phase 1 due diligence studies.
Site Assessments – Phase 2 Overview
CCRG has completed numerous and varied Phase 2 ESAs to evaluate all phases of surface and subsurface spills and leaks of contaminants.
Our work has included:
- planning and managing field explorations;
- collecting field information;
- analyzing field, chemical and hydrogeologic data;
- assessing the horizontal and vertical extent of contamination;
- evaluating remedial alternatives; and
- providing technical support for meetings, negotiations and litigation
Our staff’s extensive experience, together with our awareness of the changing regulatory climate, allows us to provide high quality services in this area of specialization. Emphasis is placed on our experience with the evaluation of vapor, dissolved and liquid phase contamination, residual soil contamination, ground water monitoring treatment design and implementation, and three-dimensional ground water flow and transport modeling.
