9.4.11.1 — HUD Multifamily Accelerated Processing (MAP)

A. The first step is to determine the extent to which EPA has completed a site characterization at the NPL site.[36]

In some cases EPA has conducted a remedial investigation or other characterization work that allows for an assessment of the area that includes the property of HUD interest, and EPA’s site characterization work may be so detailed and thorough that it can substitute for MAP requirements regarding an ASTM Phase II and/or a site characterization report. HUD would make the determination on the adequacy of available information to substitute for MAP requirements in conjunction with EPA and relevant state regulatory agencies.
In other cases EPA has conducted a remedial investigation or other characterization work at the site that shows the NPL site related contamination does not extend to the property that HUD may want to support. Examples include ground water at depth with no potential for vapor intrusion at levels of concern, or a very large site with uncontaminated areas within the boundary of the overall site.
Sometimes EPA has not yet completed a remedial investigation or other site characterization work for the area that includes the property of HUD interest. Generally, this will include sites that are newly listed to the NPL or very large sites. These sites generally undergo at least some characterization to ensure that there are no unacceptable risks that require immediate action.

B. Projects on existing or proposed NPL sites need written documentation from EPA (and sometimes also from the relevant LSTF authority) that the project is suitable for residential use. This written documentation can take four forms:

Where EPA has deleted the site from the NPL and published a deletion notice in the Federal Register. Because a site could be deleted from the NPL for a planned nonresidential use, HUD must confirm that the site is suitable for residential use.
Where EPA has issued a Site Wide Ready for Anticipated Use (SWRAU) status for the site. This indicates that the entire site is safe for the intended use and institutional and engineering controls are

in place.[37] Because a site could achieve SWRAU status for a planned nonresidential use, HUD must confirm that the SWRAU is for residential use.

Where EPA has issued a Ready for Reuse (RfR) Determination for the site. The RfR determination can apply to all of the site or to a part of the site where clean up or EC/IC has been implemented. HUD must consult with EPA to determine if the RfR determination applies to the proposed project site and that cleanup is to residential standards.
Where a site has not yet reached SWRAU or RfR status. In this case, HUD will need written documentation from EPA that an NPL site is suitable for residential use.
