Phase I Environmental Site Assessment

 

Phase I Environmental Site Assessment is a generally accepted report for evaluating the environmental liability associated with a property, and is frequently required by lenders.

An environmental consultant conducting a Phase I ESA gathers information regarding a property to evaluate whether past or present activities may have caused contamination of the soil or groundwater.  If the Phase I ESA uncovers a recognized environmental condition (REC), the environmental consultant will usually recommend a Phase II ESA, which involves invasive soil or groundwater testing. Their information sources when conducting a Phase I ESA may include the following:

 

Site Visit

-Inspection of site and observation of surrounding properties

-Note presence of hazardous materials and potential sources of contamination

-Look for evidence of past uses of the property

 

Historical Research

-Aerial photos

-City directories

-Building permits

-Topographical maps

-Oil & gas maps

-Title information

 

Geology & Hydrogeology

-Soil type

-Ground water flow

 

Regulatory Research

-Fire department and other local agencies

-State & federal environmental agencies

 

Interviews & Document Review

-Tenants, owners and property managers

-State & local regulators

-Review provided reports

 

The widely accepted standard for conducting a Phase I ESA is the American Society of Testing Materials (ASTM) 1527-2005 Standard, although specific clients and agencies may have additional requirements and standards. The ASTM E1527-05 Standard for Phase I Environmental Site Assessments has been accepted by the EPA as meeting the requirements of All Appropriate Inquiry. The EPA’s All Appropriate Inquiries Rule governing the scope of Phase I Environmental Site Assessments went into effect on November 1, 2006 and provided specific scope requirements for a Phase I ESA to meet the requirements of CERCLA’s (Comprehensive Environmental Response, Compensation and Liability Act, commonly known as the Superfund law) innocent land owner defense.
