Phase I ESA Services in Portland
Proudly Providing Phase I Assessments Across
the Portland Metro Area and Beyond
Phase I ESAs help property owners, buyers, and banks reduce the risks of dealing with hazardous materials or potential environmental liabilities on a subject property. Recognized Environmental Conditions (RECs) are defined as “the presence or likely presence of any hazardous substances or petroleum products in, on or at a property due to release to the environment; under conditions indicative of a release to the environment or under conditions that pose a material threat of future release. De minimis conditions are not recognized environmental conditions.”
Phase I ESAs may satisfy a requirement to qualify for the innocent landowner, contiguous property owner or bona fide prospective purchaser limitations on the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) liability, also known as the landowner liability protections (LLPs).
Our Phase I ESAs are conducted in conformance with American Society for Testing and Materials (ASTM) Standard Practices for Environmental Site Assessments: Phase I Environmental Site Assessment Process, E1527-21, and the standard of “all appropriate inquiry” under the ORS § 465.255 (6), and 40 CFR Part 312 Standard Practices for All Appropriate Inquires.
