(a) All equipment and materials used in the drilling of a well for the discovery of oil, gas, petroleum and hydrocarbons shall be modern and shall be kept in good working condition at all times. All drilling rigs shall be of the rotary type only to the production state of the well; and thereafter cable-tool equipment may be used for swabbing, cleaning and completion of the well. All drilling rigs shall be anchored or secured in accordance with good drilling practices.
(b) All drilling rigs or derricks shall be constructed with platform and superstructure of sufficient height to accommodate a double ram automatic blowout preventor or space-saver of "Shaffer" or "Cameron" type or the equivalent, with hydraulic blowout preventor, "Hydril" or "Reagen" above, such blowout preventors to be installed above the ground level, together with blow-line of proper size and working pressure, and with choke-manifold installed on each preventor. The blowout preventor shall be pressure tested prior to drilling operations under surface pipe, and shall be closed periodically every eight hours thereafter.
(c) When cable-tool equipment shall be used for completion of the well, they shall be equipped with master-gate, and the rig shall be equipped with lubricators while the well is being tested, swabbed or bailed. Such master-gate shall have a remote control located at least 20 feet from the well bore.
(d) Every producer or operator who shall drill a well shall, as a minimum requirement, set 500 feet of conductor pipe and cement it to the surface; then, not less than 1,000 feet of intermediate casing and cemented with cement circulated to the surface; then, a production string shall be set into or through the producing formation and shall be cemented with sufficient cement to fill up at least 300 feet above the producing formation, plus 20 percent excess cement. Each string of casing within any well shall have the fittings securely anchored to the casing immediately enclosing it.
(e) Each well shall have a separator capable of caring adequately for the production of the well, and both oil and gas, without spraying oil through the separator vent line. No gas shall be produced, wasted or allowed to escape through a separator vent line from any well. When it shall appear that an explosive mixture of gas may be accumulating near the ground, the designated city officer in charge may require that the well be shut down until such gas is dissipated.
(f) No tanks or other facility for the storage of oil, gas, petroleum or hydrocarbons produced from any well within the corporate limits of the city shall be kept, erected or maintained within the corporate limits of the city except in areas zoned as industrial and agricultural areas where such storage tanks shall be allowed. Such storage tanks shall be erected outside the corporate limits of the city, except for such installation in industrially and agriculturally zoned areas, and shall be connected to any well by pipes or pipelines by the nearest possible route.
(g) All tanks for the storage of oil permitted to be installed in industrially and agriculturally zoned areas shall be located in a pit and encircled by an embankment and a fire wall with a capacity of one and one-half times the capacity of the tank. No tank shall be located nearer than 300 feet from any building or industrial structure.
(h) All pipes or pipelines leading to or from a well location shall be buried underground to a minimum depth of 24 inches below normal surface of the ground; and before a pipeline is laid in, down or along a street, the person or company laying such line shall deposit with the city treasurer the sum established by resolution for the laying of such line; and in the construction of such lines, the permittee shall pay to the city all damages sustained by it by reason of the construction of the lines and the repair of any streets crossed by or extending along such pipelines in an amount sufficient to place the city property in the same condition as prior to the laying of the lines and shall pay to the city any and all damage incident to the taking up or repairing of the lines thereafter. No concrete or asphalt paving shall be cut or disturbed unless absolutely necessary, and then only under the supervision of the city; and the permittee shall be required to replace and repair the paving at his own expense and under the supervision of the director of public works.
(i) No rigs or heavy machinery used in connection with the drilling or operation of wells in the city shall be moved over the city streets from one location to another without obtaining a permit, which permit shall set forth the streets which may be used for that purpose.
(j) All flowing wells shall be properly equipped with well head connections designed for a minimum of 2,000 psi working pressure and 4,000 psi testing pressure.
(k) All pumping units installed shall be electrically operated and properly housed and so enclosed as to protect the public. All electrical switches and electrical outlets shall be enclosed and be explosion-proof.
