A holder of a DEQ recognition may apply to convert the recognition to a DEQ-issued permit, license or certification at any time. On request, DEQ shall apply the fee paid by the applicant for the recognition to the fee due on the application for conversion and cause the effective date of the DEQ permit or license to be the date the application for reciprocity recognition was received by DEQ.
