A Level I environmental assessment report generally follows the guidelines of the_____________________.

• A. Environmental Protection Agency
• B. American National Standards Institute
• C. International Organization for Standardization
• D. American Society for Testing and Materials

Answer: (D)

A Level I environmental assessment report is guided by a standard set of procedures published by ASTM International, specifically ASTM E1527 for Phase I ESAs. This standard defines the entire process—records review, site reconnaissance, interviews, and documentation—so that findings are consistent, defensible, and widely accepted in real estate transactions and lending. The emphasis is on identifying recognized environmental conditions and outlining steps taken to assess potential risks in a systematic way. EPA guidance exists for related inquiries and regulatory expectations, but the formal, widely used framework for conducting Level I ESAs in the U.S. is ASTM. ANSI deals with accreditation and standards administration, not the practice itself for ESAs, and ISO provides international standards that are not the prevailing baseline for U.S. Phase I assessments.
