We've been asked to perform a Phase I ESA in support of NEPA review and preparation of a HUD Environmental Review Rercord. I'm not very familiar with HUD requirements for a Phase I, but it looks like ASTM E1527-05 is sufficient. I see that HUD's MAP guidance also requires the Vapor Encroachment Screen from ASTM E2600-10. This isn't a MAP project, but we'll probably include the screen anyway.
Are there any other HUD requirements that go beyond ASTM E1527-05 and ASTM E2600-10 that we should consider?
