Upon completion and passing of your grade A exam, DMACC will send the DNR your score. Send the DNR your DNR Grade A Operator Application. The DNR will process your score and mail each passing applicant a “PASS letter.” Please allow 48 to 72 business hours to process. Mail the “Pass Letter” along with the application fee to the DNR. The fee can also be paid online on the Operator Certification Database Website found in the Apply/Register area. Once your fee is received your Grade A Water Operator Certification will come in the mail. If you have any questions, contact Laurie Sharp, IDNR at 515-725-0284.
