Standard Practice for Assessment of Vapor Intrusion into Structures on Property Involved in Real Estate Transactions
SIGNIFICANCE AND USE
Uses—This practice is intended for use on a voluntary basis by parties who wish to conduct a VIA on a parcel of real estate, or more specifically conduct a screening evaluation to determine whether or not there is potential for a VIC, and if so, identify alternatives for further investigation. To determine whether the vapor intrusion exposure pathway is complete and, if so, whether it poses or may pose an unacceptable risk to human health (that is, whether a VIC exists), this practice directs the user and environmental professional to existing federal or state vapor intrusion policy, regulation and guidance (refer to Appendix X5 and Appendix X9). The process defined in this practice begins with a reasonably conservative screening process that requires information generally collected as part of a Practice E 1527 Phase I ESA. If a pVIC is identified in this initial screening, the process gradually progresses toward a more complex assessment involving increasingly greater use of site-specific data. For those sites unable to be screened out, the process provides alternative methods to determine whether a VIC exists. If a VIC is found to exist, the process describes general mitigation alternatives. This practice is intended primarily as an approach to conducting an inquiry designed to identify pVICs or VICs in connection with a property involved in a real estate transaction. This practice is intended to reflect a commercially practical and reasonable inquiry (see 1.2). The practice can be applied to property with existing structures, property with structures that will be substantially rehabilitated, property without existing structures but having planned structures (for example, property in development), or property without existing structures and with no planned structures (for example, undeveloped property with no planned development).

SCOPE
1.1 Purpose—The purpose of this practice is to define good commercial and customary practice in the United States of America for conducting a vapor intrusion assessment (VIA) on a property parcel involved in a real estate transaction with respect to chemicals of concern (COC) that may migrate as vapors into existing or planned structures on a property due to contaminated soil and groundwater on the property or within close proximity to the property. This practice may be used as a voluntary supplement to Practice E 1527 and does not alter or in any way define the scope of that practice. In addition, performance of this standard is not a requirement of and does not constitute, expand, or in any way define “all appropriate inquiry” as defined or approved by U.S. EPA under CERCLA and the regulations thereunder, including 40 CFR Sec. 312.11.
1.1.1 Vapor Intrusion Condition (VIC)—In defining a standard of good commercial and customary practice for conducting a VIA on a parcel of property, the goal of the process established by this practice is to identify whether or not a vapor intrusion condition (VIC) exists or is likely to exist on the property. The term VIC means the presence or likely presence of any COC in the indoor air environment of existing or planned structures on a property caused by the release of vapor from contaminated soil or groundwater either on the property or within close proximity to the property, at a concentration that presents or may present an unacceptable health risk to occupants. The term is not intended to include de minimis conditions that do not normally represent an unacceptable health risk to occupants and that generally would not be the subject of an enforcement action if brought to the attention of appropriate governmental agencies. A condition determined to be de minimis does not represent a VIC.
