If an eligible entity wishes to seek PA funding, it must first submit a Request for Public Assistance (RPAs) to FEMA through the Recipient (VEM). FEMA accepts RPAs through PA Grants Portal. Prior to submitting RPAs to FEMA, the Recipient (VEM) must review and approve each RPA and provide its assessment of the Applicant’s risk of noncompliance as required by 2 C.F.R. § 200.331(b).
