Phase I ESA in Buffalo, NY
For Buffalo commercial-RE buyers, lenders and attorneys requiring AAI-compliant Phase I ESAs under CERCLA.
Specific to Buffalo
Phase I Environmental Site Assessments (ESA) for Buffalo, NY commercial real estate transactions follow the ASTM E1527-21 standard, which satisfies EPA's All Appropriate Inquiries (AAI) rule under CERCLA. The Phase I is the foundational due-diligence document for commercial buyers, commercial lenders, and SBA loans on real estate. Buffalo's industrial history makes Phase I work particularly important here. Former gas stations, dry cleaners, manufacturing facilities, machine shops, and underground storage tank locations are common Recognized Environmental Conditions (RECs) on Buffalo commercial parcels. We pull historical aerial photographs (1938, 1958, 1978, 1995 standard date set), Sanborn fire insurance maps, city directory listings, NY DEC Spills Incident Database, EDR-style regulatory database screens, and federal/state environmental databases (CERCLIS, RCRA, LUST, UST, HSWA). Site reconnaissance includes physical inspection, adjoining property review (industry-standard 1 mile for federal databases, 1/8 to 1/2 mile for state databases per ASTM E1527-21 distance criteria), and structured stakeholder interviews. The deliverable is a written report meeting AAI standard, executed by Mason Bridges as the Environmental Professional, with the appropriate professional qualification documentation appended.
