Cleanup ProgramJune 2014

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

• 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.
