    Title:
    Proper language to incorporte VI screen into Phase I proposal!
    Content:

    Hello Commonground,


    I have a client who is looking to incorporate VI into their proposals for Phase Is, but are concerned as to the most appropriate way to do this.


    The E-2600 guidelines for VI note 4 tiers in the methodology, however not all 4 tiers may be warranted for a given project. My client is concerned as to how to avoid any ambiguity on how much of the 4 VI tiers they will be responsible for if incorporating into the Phase I.

    Does anyone have any thoughts or examples of language used for including VI as a potential scope in their proposal?� As well, any other thoughts and advice would be appreciated.

    Thank you

    Jim Pepe

      In my view, what might or might not be included in the vapor intrusion scope of work added to the Phase I should reflect the client's risk tolerance. For example, clients with a very low risk tolerance (such as many of the box stores) might include both Tier 1 and Tier 2 screening in the VI scope of work.

      If a pVIC is identified after VI screening, the client (working with the EP) will need to make a decision about whether to proceed to Tier 3 (VIC confirmation), or proceed to Tier 4 (pre-emptive mitigation), or choose some other alternative. For this reason, in my view, clients interested in adding vapor intrusion to their Phase I scope of work should develop a pVIC strategy BEFORE the Phase I is conducted. The strategy should focus on what would be done if a pVIC is identified in the screening.
