Environmental Due Diligence

Environmental Due Diligence

It’s critical to understand all potential environmental concerns with a property before making a financial investment.

Our environmental consulting services provide the due diligence clients need to identify and reduce environmental risk. 

SBA Records Search with Risk Assessments (RSRAs)
The U.S. Small Business Administration (SBA) utilizes RSRAs for property uses that do not match one of the NAICS codes of environmentally sensitive industries. The RSRA report is a limited assessment that evaluates the likelihood of contamination labeling the property “high risk” or “low risk.”

Environmental Transaction Screens
Environmental Transaction Screens are utilized when a determination is made that a full Phase I Environmental Site Assessment is not warranted. Environmental Transaction Screens are limited in scope and are used to identify potential environmental concerns associated with a property. Environmental Transaction Screens are conducted in accordance with industry standards established by the American Society of Testing and Materials (ASTM) in E1528.

Phase I Environmental Site Assessments (ESAs)
ESAs are essential for any commercial real estate transaction. They establish the foundation for qualifying for landowner liability protection under CERCLA and many state environmental regulations. The goal of a Phase I Environmental Site Assessment (ESA) is to help our clients better understand a property’s environmental risks in a clear, unambiguous manner. All BBG ESAs are conducted in accordance with industry standards established by ASTM, Housing and Urban Development (HUD), Freddie Mac, and Fannie Mae, as well as client specific scopes of work. Phase I ESAs often include ASTM non-scope considerations such as asbestos-containing materials, lead-based paint, radon, lead in drinking water, and microbial growth. BBG’s Phase I ESA reports meet the most current ASTM E1527 Standard and the USEPA All Appropriate Inquiry requirements.

Phase II Assessment and Remediation
The purpose of a Phase II Subsurface Investigation is to confirm or refute the existence of contamination at a property and to quantify the extent of the contamination. The scope of work for the investigation varies based on the nature of the concern and the needs of the client. Subsurface Investigation Reports include a discussion of the findings of investigation, conclusions, recommendations and, as necessary, remediation cost estimates. Based on Phase II results, BBG can design an appropriate and effective remediation scope of work to meet client specific goals, as well as regulatory requirements, and provide field series and/or project oversight through successful project completion. Detailed reporting of remediation procedures, sampling and analysis results, conclusions and recommendations are provided in order to meet client needs and regulatory standards.

Third-Party Desktop Reviews
When required, the BBG Assessment team reviews reports prepared by others for scope of compliance, quality of reporting and presentation of findings, and for all appropriate conclusions and recommendations. BBG conducts Desktop Reviews of Phase I and Phase II Environmental Assessments to provide the client with confirmation that the scope of work has been performed, the report is complete, and the conclusions and recommendations are appropriate and in compliance with industry standards and client protocol. Third-Party Desktop Reviews are typically presented in a brief summary letter format.
