The agency shall make a determination of the eligibility for the National Register for each site identified within the undertaking's area of potential effects.

If the SHPO does not reply within the time specified in Subsection 9-8-404(3)(a) or within the time period agreed to by the parties, then the agency may presume that the SHPO concurs with the agency.3.
