Updated items from ASTM Standard E-1527-13:

As of December 31, 2013, EPA finalized a rule that the ASTM Standard E-1527-13 is a standard by which parties may comply with the "All Appropriate Inquiries" Rule, 40 CFR Part 312. EPA indicated that it does intend to propose an amendment to 40 CFR Part 312 removing reference to the E1527-05 standard. EPA does recommend that the new standard be used.

The standard does not have any substantial changes to the previous standard. Items such as vapor intrusion and regulatory file reviews are something that our company has conducted previously as part of a “common sense” approach to identifying potential significant environmental liabilities based on proper scientific analysis of available information that helps determine the potential for releases into the soil and/or groundwater at a property. The standard includes the following clarifications and revisions.

Innocent Landowner's Defense

Entities that acquire property and had no knowledge of the contamination at the time of purchase may be eligible for the "innocent landowner" (ILO) defense to Superfund/CERCLA liability. For a more detailed discussion of this type of defense, we recommend reading the United States Environmental Protection Agency (USEPA) discussion here:

Innocent Landowners.

Phase I Environmental Site Assessment Advice

The ESA report is a specific study for the presence or potential presence of hazardous substance or petroleum product releases into the soil and/or groundwater, as well as, into structures, which can migrate through the floor to the subsurface. The Phase 1 ESA report does not include the study of building materials or building systems. To obtain a proper report, you should hire a geologist, engineer or scientist with knowledge of soil science, groundwater hydrology and regulatory conditions. The most common types of environmental liabilities that are found during real estate transactions are things like: leaking underground storage tanks, leaking hazard waste containers, spills and other subsurface contamination. These are the issues that need to be addressed in a more immediate manner, in order to occupy the property, redevelop or to get a loan or to buy/sell the property.
