ARPA Grant Management Guide: Audits


If your municipality receives more than $750,000 in federal funds from ALL sources, not just ARPA and not just at the library, then an audit of your grant funds that meets the requirements of the Single Audit (previously known as the OMB Circular A-133) is required. 

According to the SINGLE AUDIT ACT AMENDMENTS of 1996 (P.L. 104-156), external or internal audits must be made in accordance with generally accepted government auditing standards (GAGA) issued by the Comptroller General of the United States, which are applicable to federal audits.

How do I meet the requirement?

Your municipality's regular annual or bi‑annual audit should meet the requirements. Talk with your municipal treasurer to be sure. Audits of non‑profit organizations must also be in compliance with 2 CFR 200.

What to send the MBLC

In order to comply with the audit requirement, you may choose one of the following options:

  1. Send one copy of the entire audit report
  2. Send one copy of the audit cover letter, the entire audit findings, and the section of the audit pertaining to your ARPA grant (i.e. the Federal Financial Assistance portions).

If you select option #1 above, be sure that it is the entire report. Often the Federal Financial Assistance portion of the audit is bound separately, but it is essential we receive that part.


  • The  CFDA (Catalog of Federal Domestic Assistance) number for ARPA is 45.310
  • The audit is due to the MBLC thirty days after it is completed by your municipality.
  • It is necessary to have audits done for the entire period of disbursements and expenditures. With fiscal year spending, this may result in more than one audit. All relevant audits should be sent.


This website, and other programs of the MBLC, is funded in part with funds from the Institute of Museum and Library Services, a federal agency that fosters innovation, leadership, and a lifetime of learning.
