Preliminary Environmental Assessment

To protect human health and the environment, the Department coordinates with its bureaus and offices to minimize exposure to liabilities and potential remediation costs by avoiding the acquisition of contaminated real property, unless specifically directed by Congress, required by court mandate, or authorized by the Secretary or the Secretary’s designated representative.

When a bureau or office plans to acquire contaminated property—except under limited circumstances—it is the Department’s policy to preserve potential defenses to CERCLA and/or OPA liability, when prudent and practicable, by conducting a Preliminary Assessment–Environmental Site Assessment (PA ESA). The PA ESA is one of the steps required to meet the All-Appropriate Inquiry (AAI) standard.

The Office of Environmental Policy and Compliance (OEPC) may assist bureaus and offices in interpreting and implementing these requirements. OEPC may also issue or update additional guidance on land acquisition and is responsible for informing bureaus and offices of relevant ASTM standard updates in accordance with EPA and U.S. Coast Guard AAI regulations.
