Phase I Environmental Site Assessments (ESA)
• Defined as a report prepared for a real estate holding that identifies potential or existing environmental contamination liabilities.
• It is generally considered the first step in the process of environmental due diligence.
Not Suggested
• Comprehensive Environmental Response,Compensation and Liability Act (CERCLA, also
referred to as Superfund)
Why Do You Want a Phase I ESA?
• All Appropriate Inquiry vs. “But I got a good
deal.”
The Standard and the Phase I ESA
• American Society for Testing and Materials International (ASTM) 1527-13
• AKA Phase I Site Assessment6 Records Review
6 Site Reconnaissance
6 Interviews
6 Report
• Goal: Identify Recognized Environmental Conditions (RECs)
• Conducted by an Environmental Professional
The Phase I ESA Report• Narrative: Site description, records review,
site reconnaissance, interviews, findings & conclusions, deviations, signature and qualifications of Environmental Professional.
• Appendices: Site map, photos, historic photos/maps, topographical maps, regulatory records documentation, interview documentation.
What is a Recognized Environmental Condition (REC)
Basically, the presence or likely presence of any hazardous
substances or petroleum products on a property where there is a
significant potential that a hazardous substance has been released into the environment.
This is a Wreck…….not a R.E.C.
What is Considered a REC?
Dry Cleaning Solvents
Petroleum Products
Pesticides
What is Considered a REC?
Polycyclic aromatic hydrocarbons (PAHs)
Polychlorinated biphenyls (PCBs)
Heavy Metals: e.g. Mercury
What Things Aren’t Looked For?
Mold
Septic Tanks
Bird Drippings
Likely Places for
RECs
Example: The Former
Folgers Coffee Company
(UST) Underground Storage Tank
RECs identified by the Phase I
ESA
My RECs have been identified
Phase II ESA• ASTM E 1903-11
• Developed from the RECs identified in the Phase I ESA
• Invasive Investigation, though not Exhaustive
Phase II ESA Sampling• Surficial Soil Samples
• Subsurface Soil Samples
• Surface Water Samples
• Groundwater Samples
• Asbestos-Containing Material (ACM)
• Lead-Based Paint (LBP)
The Phase II ESA Report• Narrative
Background Info Work Performed Results of Investigation Interpretations/Conclusions
• Tables• Figures• Appendices
Site Photos Boring Logs/Monitoring Well Construction Lab Data with Quality Control Information

• Following a Phase II
• More Detail
• Investigating a Particular Area from a Phase II or Expanding Investigation of Original Area
Phase II ESA Addendum
Phase I and Phase II Environmental Site Assessment (ESA) Process. Are there any Recognized Environmental Conditions (RECs)?
Yes
Phase II ESA needed
Contamination
Above Lowest Cleanup Levels
Phase II ESA Addendum is needed or enrollment in
the BVCP is recommended
Below Lowest Cleanup Levels
No further investigation is needed.
No
Phase II ESA is not needed
Quick Overview of Area Wide Brownfield Inventory
• You get a list of properties that are likely Brownfields in a community.
• Each property has a score (0-7) based on the likelihood of hazardous waste contamination.
• This tool will help communities prioritize sites for redevelopment.
• More from Christine O’Keefe tomorrow afternoon.
