If the United States Department of Agriculture’s Food and Nutrition Service creates and makes available to the states a waiver permitting recipients of benefits provided under the Supplemental Nutrition Assistance Program or the Special Supplemental Nutrition Program for Women, Infants, and Children to use their benefits to purchase diapers or menstrual hygiene products such as tampons, sanitary napkins, and feminine wipes, then the Department of Human Services shall apply for the waiver. If the United States Department of Agriculture approves the Department of Human Services’ waiver application, then the Department of Human Services shall adopt rules and make other changes as necessary to implement the approved waiver.
