If completion of this process conflicts with the date set for submission of the feasibility and plan of operation report, the applicant shall contact the department to establish a later date for submission of the feasibility and plan of operation report or the trial burn results. Trial burn results shall be submitted prior to issuance of the license. When the applicant submits a trial burn plan with the feasibility and plan of operation report, the department will specify a time period prior to license issuance in which the trial burn shall be conducted and the results submitted.
