Okla. Admin. Code § 310:410-3-42
A vendor may voluntarily withdraw from participation in the WIC retail vendor program with approval of the department. A request for such withdrawal shall be made in writing by the vendor and sent to the department at least fifteen (15) calendar days in advance of the desired date of withdrawal. If at the time of the requested withdrawal, the vendor owes a fine assessment or any other monies resulting from a violation of this part, such penalty and other monies due shall be paid in full prior to withdrawal from the WIC retail vendor program. The State agency shall not accept voluntary withdrawal of the vendor from the Program as an alternative to disqualification for the violations listed in 7 CFR §246.12(k) (1) (i) through (k) (1) (iv), but shall enter the disqualification on the record.
