NEW and RENEWAL Applicants

USDOT RIN approvals are granted for a 5-year period and a renewal application must be made to the USDOT approvals office 60 days prior to expiration.

A RIN holder must arrange for an independent inspection agency, approved by the USDOT, to perform an on-site review of its inspection or requalification operation. The company seeking approval must bear the cost of the inspection.

Applications must be made in accordance with 49 CFR sections 107.805 and 107.705

If the inspection performed by an independent inspection agency is completed with satisfactory results, the applicant must submit a letter of recommendation from the independent inspection agency, an inspection report, and an application containing the information prescribed in the above referenced sections.

FOR a RENEWAL ONLY {excerpt from 49 CFR 107.705} For an approval with an expiration date, each application for renewal or modification must be filed in the same manner as an original application. If, at least 60 days before an existing approval expires the holder files an application for renewal that is complete and conforms to the requirements of this section, the approval will not expire until final administrative action on the application for renewal has been taken. Operation under an expired approval not filed within 60 days of the expiration date is prohibited.

Please schedule your renewal inspection at least 90 to 180 days prior to the approval expiration date.
