Phase I Environmental Site Assessment (ESA)

for Midland, TX; Odessa, TX; Abilene, TX; San Angelo, TX; Lubbock, TX; Houston, TX; Dallas, TX; Fort Worth, TX; Hobbs, NM; Carlsbad, NM; Lafayette, LA & the Surrounding Areas

A Phase I Environmental Site Assessment (ESA) is a report that reviews a property's history to identify potential environmental contamination risks, such as past use of underground storage tanks or dry-cleaning chemicals. This is a non-intrusive process that includes a historical records review, a site visit, and interviews, but it does not involve any physical sampling or testing. It is commonly required by lenders and is a crucial part of due diligence for commercial real estate transactions to mitigate potential legal and financial liabilities. At eTech Environmental & Safety Solutions, Inc, we help buyers, lenders, developers, brokers, and property owners navigate the environmental due diligence process with confidence. Our experienced environmental professionals provide thorough, ASTM-compliant Phase I environmental site assessments for clients in Odessa, Midland, Dallas, Fort Worth, Houston, Lubbock, Abilene, San Angelo, TX; Denver, CO; Oklahoma City, Tulsa, OK; Hobbs, NM; and the surrounding areas.

Key Components of a Phase I ESA

  • Historical Research: Reviewing historical records like aerial photos, city directories, and fire insurance maps to understand the property's past uses
  • Site Reconnaissance: A physical inspection of the property to look for signs of contamination, such as chemical storage or evidence of leaks
  • Regulatory File Review: Checking local, state, and federal databases for records related to environmental permits, violations, or cleanups at the property and surrounding areas
  • Interviews: Speaking with current and past owners, tenants, or government officials who may have knowledge of the property's environmental history

What a Phase I ESA Does Not Include

  • Physical Sampling: The assessment does not involve collecting or analyzing soil, groundwater, or building materials.
  • Specific Environmental Issues: It is not designed to identify issues like asbestos, mold, lead-based paint, or wetlands.

Purpose and Outcomes

  • Identifies Recognized Environmental Conditions (RECs): The primary goal is to identify any RECs, which are the presence or likely presence of hazardous substances or petroleum products due to a release to the environment.
  • Mitigates Liability: It helps buyers and lenders protect themselves from potential future liability for contamination through legal defenses such as the innocent landowner defense.
  • Informed Decisions: The report provides information to help potential buyers make informed decisions and to negotiate terms of a sale.
  • Determines Next Steps: If the Phase I ESA finds potential issues, it will recommend further investigation, such as a Phase II ESA, which includes intrusive sampling and analysis.
