Okla. Admin. Code § 310:410-3-13
Foods which qualify for delivery to WIC participants shall be determined by the department and placed upon a list which shall be made public. Changes made to the WIC food list by the department, including addition and deletion of eligible foods, shall be distributed to all local agencies, eligible participants and WIC vendors prior to implementation. If a vendor intends to utilize a WIC food list which differs in form from the WIC food list distributed by the department, such use shall require prior approval of the department. To obtain such approval, the vendor shall submit a request for such use in writing to the department and shall include a copy of the food list it intends to use. The department shall review the food list submitted and inform the vendor whether it shall approve or disapprove of the use of such list based upon the current department list. Disapproval of such a request shall not give rise to any right of administrative appeal.
