4.1?UsesThis guide is intended for use on a voluntary basis by parties who wish to conduct a VES on a parcel of real estate to determine if a 4.2?Clarifications on Use:? 4.2.1?Use in Conjunction with E1527 Phase I ESAThis practice, when used in conjunction with E1527 Phase I ESA, may assist the user and environmental professional in developing information about VECs associated with a TP. This guide has utility for a wide range of persons, including those who may not be involved in a 4.2.2?Independent UseThis guide may be used independent of an E1527 4.2.3?Site-SpecificThis guide is property specific in that it relates to screening of VECs associated with a specific parcel of 4.3?Who May ConductA 4.4?Additional Services Contracted ForAdditional services may be contracted for between the 4.5?PrinciplesThe following principles are an integral part of this guide and are intended to be referred to in resolving any ambiguity or exercising such discretion as is accorded the 4.5.1?Uncertainty Not Eliminated in ScreeningNo vapor encroachment screen, such as included in Sections 8 and 9 of this guide, can wholly eliminate uncertainty regarding the identification of VECs in connection with a TP. Screening is intended to reduce, but not eliminate, uncertainty regarding whether or not a VEC exists in connection with a property. 4.5.2?Not ExhaustiveThe guide is not meant to be an exhaustive screening. There is a point at which the cost of information obtained or the time required to gather it outweighs the usefulness of the information and, in fact, may be a material detriment to the orderly completion of real estate transactions. One of the purposes of this guide is to identify a balance between the competing goals of limiting the costs and time demands inherent in performing a 4.5.3?Level of Investigation is VariableNot every property will warrant the same level of screening. The appropriate level of screening should be guided by the nature of the property subject to screening and the information already available or developed during the course of the investigation. 4.5.4?Comparison with Subsequent InvestigationIt should not be concluded or assumed that an investigation was not adequate because the investigation did not identify 4.6?Continued Viability of VESSubject to subsection 4.7, a VES conducted according to the procedures presented in this guide and completed less than 180 days before the date of acquisition of the property or, for transactions not involving an acquisition, the date of the intended use of the 4.6.1?Reviews of federal, tribal, state, and local government records; 4.6.2?Update on the operations existing at the 4.6.3?Evaluation of any new potential preferential pathways for vapor migration; 4.6.4?Screening of any new contaminated plume migration that might cause a 4.6.5?Screening of any new contaminant releases in the 4.7?Use of a Prior VES ScreenThis guide recognizes that VESs performed in accordance with this guide will include information that subsequent users may want to use to avoid undertaking duplicative screening procedures. Therefore, this guide describes procedures to be followed to assist users in determining the appropriateness of using information in VESs performed more than one year prior to the date of acquisition of the property or, for transactions not involving an acquisition, the date of the intended use of the 4.7.1?Use of Prior InformationSubject to the criteria set forth in subsection 4.6, users and environmental professionals may use information in a prior VES provided such information was generated as a result of procedures that are consistent with the procedures presented in this guide. However, such information should not be used without current investigation of conditions likely to affect VECs in connection with the TP. Additional investigation may be necessary to document conditions that may have changed materially since the prior 4.7.2?Contractual Issues Regarding Use of a Prior VESThe contractual and legal obligations between prior and subsequent 4.8?Actual Knowledge ExceptionIf the user or environmental professional conducting a 4.9?Rules of EngagementThe contractual and legal obligations between an 1.1?PurposeThe purpose of this guide is to provide practical guidance and a useful process for conducting a 1.1.1?Vapor Encroachment Condition (VEC)The goal of conducting a 1.1.2?Federal, State, and Local Environmental LawsThis guide does not address requirements of any federal, state, or local laws with respect to vapor intrusion. Users are cautioned that federal, state, and local laws, regulations, or policy may impose vapor encroachment screening or vapor intrusion assessment obligations that are beyond the scope of this guide (information is provided in Appendix X5 and Appendix X9). Users should also be aware that there may be other legal obligations, for example, disclosure, with regard to 1.1.3?DocumentationThe scope of this guide includes investigation and reporting actions. Sufficient documentation of all sources, records, and resources used in the investigation procedures that are set out in this guide should be provided in the 1.2?ObjectivesObjectives guiding the development of this guide are: (1) to synthesize and put into writing a practical guide for conducting a VES on a property involved in a 1.3?Considerations Outside the ScopeThe use of this guide is strictly limited to the scope set forth in this section. Section 11 of this guide identifies, for informational purposes, certain tasks (not an all-inclusive list) that may be conducted on a property that are beyond the scope of this guide but that may warrant consideration by parties to a 1.4?UnitsThe values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5?Organization of this GuideThis guide has eleven sections and nine appendices. The appendices are included for informational purposes and are not part of the procedures prescribed in this guide.
