Highlights of ASTM Changes – ASTM E 1527-13

On November 6, 2013 the American Society for Testing and Materials (ASTM) issued its updated standard practice for conducting Phase I Environmental Site Assessments – ASTM E1527-13. The USEPA is expected to accept the new ASTM standard as compliant with the “All Appropriate Inquiry” (AAI) rule (40 CFR Part 312) in early 2014.

In our on-going effort to keep our clients up to date on the ever changing regulations and standards related to environmental assessments, below is a brief summary of the major changes associated with the new standard. If you have any questions or would like more information, please contact IES and we would be happy to assist you.

 

Revision and addition of definitions:

  • Definition of Recognized Environmental Condition (REC) has been improved/clarified
  • Definition of Historical Recognized Environmental Condition has been revised.
  • Controlled Recognized Environmental Condition (CREC) added.

 

Vapor Migration Screening:

  • Requires vapor migration in the Phase I to be taken into consideration.
  • Vapor migration is different from vapor intrusion, which outside the scope of an E1527-13 Phase I Assessment.
  • Alternative for conducting vapor migration assessment include Tier 1 E2600-10 or company’s own methodology.

 

Regulatory File Reviews:

  • Former standard (E1527-05) did not have a section on regulatory agency file reviews.
  • E 1527-13 requires review of regulatory files on Target Property and adjoining properties unless Environmental Professional deems it unnecessary and provides rationale for their decision (i.e. not available for a reasonable cost or within a reasonable time frame).

 

IES is pleased to inform our clients that the new standard will NOT result in an increase in the cost or turnaround time of our Phase I Environmental Site Assessments.
