# §310.16. What kind of cost documentation is necessary?


Cost documentation must be adequate for an audit. At a minimum, you must:

- (a) Include a description of the temporary emergency measures for which you request reimbursement;
- (b) Specify the local agency that incurred the cost, (such as, the Town Fire Department, the County Health Department, or the City Department of Public Works);
- (c) Include invoices, sales receipts, rental or leasing agreements, or other proof of costs you incurred; and
- (d) Certify that all costs are accurate and that you incurred them specifically for the response for which you are requesting reimbursement.
