7. Alternative evaluation approaches

There are many different approaches that may be utilized for the evaluation of the potential risks associated with petroleum and the VIAP than what is described in this document. An alternate approach that may be more cost efficient or save time could be considered, especially if the site doesn’t screen out using the steps outlined in Sections 3 through 6. Many of the approaches that can be applied are site-specific which is why they are not described in detail in this document. The obligation to identify an alternative approach and provide justification on why the approach meets the obligations of Part 201 is required of the person proposing the response activity.

Example site conditions that may be encountered and alternative or site-specific evaluation approaches are provided and discussed in Attachment E.4.
