What is a Phase I Environmental Site Assessment (ESA)?

A Phase I Environmental Site Assessment (ESA) is the first step in ensuring the property you’re buying is safe, has no hidden risks, and is compliant with regulations. Under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), property owners can be held liable for the cost of pollution cleanup if the property is not properly assessed before purchase. Most lenders will require a Phase I ESA before loan approval.

While not every Phase I ESA is the same and is tailored to the client’s needs, the basic steps are as follows:

  • Pre-Assessment Preparation - collecting all the necessary information on the property including its history, regulations, and ordinances

  • Site Inspection - surveying the site in person to visually inspect for any signs of potential contamination

  • Interviews and Documentation - interviewing property owners, neighbors, and local officials along with anyone else who may have interacted with the property

  • Data Compilation and Analysis - the ERG environmental specialist will compile all their findings and put them together for the client so it’s easy to read and understand

  • Reporting and Recommendations - the final report is prepared and the ERG team will offer expert advice to help with any environmental issues

The Phase I ESA is compiled per the American Society for Testing and Materials (ASTM) standards and most reports are broken into the following components.

  • Executive Summary

  • Findings

  • Recommendations

If, after inspection, no environmental hazards have been found, the report can be sent to your lender, and you will have peace of mind that the property you’re buying is safe, compliant, and of appropriate valuation.

However, if the property has identified environmental risks, our ERG professional will share tips on handling and mitigating those risks in a timely and cost-efficient manner. Some possible next steps would be:

  • Disposing of built-up waste

  • Excavating and removing contaminated soils

  • Treating contaminated soils or groundwater

  • Building barriers to prevent the spread of contamination

Whether you’re buying, selling, or refinancing a property, a Phase I ESA is an essential first step. Contact ERG today and an environmental specialist will get back with you to start the journey to peace of mind.
