Okla. Stat. tit. 59, § 396.30
No person shall dispose of the body of any deceased person by cremation, dehydration, combustion, or other similar means, within the State of Oklahoma, without first having obtained from the State Commissioner of Health an annual license to operate a crematory. Application for such annual license shall be made to the Commissioner upon forms prescribed and furnished by him, shall give the location of the crematory, and such other information as the Commissioner shall require, and shall be accompanied by the license fee not to exceed Twenty-Five Dollars ($25.00), to be determined by the State Board of Health. Annual licenses shall expire on the 31st day of December each year, shall specify the name or names of the owners of the crematory and the location thereof, and shall not be transferable either as to the ownership of the crematory or as to the location thereof. The first annual license issued for any crematory at any location shall not be issued by the Commissioner until he has been satisfied that the crematory is, or will be, so constructed as to be capable of reducing the body of a deceased person to a residue which shall not weigh more than five percent (5%) of the weight of the body immediately after death. Such a showing may, but need not, be required by the Commissioner for any subsequent annual license issued for the same crematory. All crematories shall be subject to inspection, at all reasonable times, by the Commissioner or his duly authorized agents or employees.
