Except as provided in section 20-21, within 1,000 feet of any occupied structure a maximum of two 500-barrel tanks for crude oil storage may be constructed in connection with any one producing well within the city limits. There shall be no limitation on the size or number of storage tanks that may be constructed in the area more than 1,000 feet from any occupied structure. Each tank shall be equipped with flame arresters and shall be so constructed and maintained as to be vaportight. Each tank or tank battery shall also be surrounded with an earthen fire wall which shall at all times be free of vegetation and which will be at such distance from the tank as will under any circumstances hold and retain at least 1½ times the maximum capacity of such tank. The area outside each tank but contained within the earthen fire wall shall be properly drained at all times. A permittee may use, construct, and operate a steel conventional separator, and such other steel tanks and appurtenances as are necessary for treating oil, with each of such facilities to be so constructed and maintained as to be vaportight. Each oil gas separator shall be equipped with both a regulation pressure relief safety valve and a bursting head.
