Phase I Environmental Site Assessment

Ark routinely performs inexpensive Phase I Environmental Site Assessments (ESAs) also known as "Environmental Report" for many banks, real estate agents, and corporate clients. Based in Indianapolis, Indiana, Ark is well positioned to serve a diverse, nationwide client base.

Phase I Environmental Site Assessment (Phase One)

A Phase I Environmental Report is generally considered the first step in the process of environmental Due Diligence. Standards for performing a Phase I Site Assessment have been promulgated by the US EPA and are based in part on ASTM in Standard E1527-13. The Phase I site inspection includes examination of potential adverse environmental impact including, but not limited to, soil contamination and ground water and surface water quality through a site inspection and review of the property's history.

Phase I ESAs are performed for buyers, sellers, brokers, and lenders who are involved in the sale, purchase or lease of industrial, commercial, and real estate properties and are typically required by lenders in order to assure that properties do not exhibit environmental conditions that could diminish the value of the property, the ability of the borrower to repay, or to establish baselines to allocate responsibility for clean-up costs.

Qualification to perform Phase I ESA

40 CFR Part 312.10 defines an Environmental Professional as someone with:

  • A current Professional Engineer’s or Professional Geologist’s license, or registration from a state or U.S. territory with 3 years equivalent full-time experience.
  • A Baccalaureate or higher degree from an accredited institution of higher education in a discipline of engineering or science and 5 years equivalent full-time experience.
