44 CFR 206
Subpart H: Public Assistance Eligibility
Subpart H provides the "Four Pillars of Eligibility": Eligible Applicant, Facility, Work, and Cost. It distinguishes between Emergency Work (Categories A-B) and Permanent Work (Categories C-G). For Grant Managers, this section is the primary defense against auditors claiming that a facility was not in active use or the work was "pre-existing maintenance."
