In no event shall any of such substances be permitted to escape from the premises owned, leased or controlled by the person carrying on such operations by seepage, overflow or otherwise, nor flow across the surface of the ground, or upon any public way, into any storm or sanitary sewer, drainage ditch, upon any gutter or paving or into any gulley, stream or tributary within the city.

C. Earthen Retaining Walls: An earthen retaining wall of adequate size for the terrain shall be constructed on the low side of all well sites situated within the city, on sloping or unlevel ground. The top of the retaining wall shall be at least as high as the top of the christmastree or other wellhead connections on any completed well, or at least as high as the ground at the point where surface casing is set in the well when drilling.
D. Storage Tanks: Storage tanks or other types of tanks containing flammable substances used in connection with any oil, gas or disposal well within the city shall have earthen embankments constructed around them of sufficient size and height to be able to adequately contain one and one-half (11/2) times the volume of such tanks in the event of a rupture thereof at the floor of such tank. No drain plugs, openings or siphons shall be placed in the walls or dikes which will permit the escape of any liquids through the same. In no event shall any such tank be located nearer than one hundred feet (100') to a dwelling or business structure, street or highway within the city.
E. Internal Combustion Engines: No steam, gasoline, natural gas, diesel or other internal combustion engine of any kind shall be operated in conjunction with the drilling or operation of an oil or gas well within two hundred fifty feet (250') of any dwelling or business structure within the city.
F. Location Near Church, School Or Hospital: No oil, gas or disposal well shall be drilled, operated or maintained, nor shall any operations in connection therewith be carried on or conducted within two hundred fifty feet (250') of any church, school or hospital building within the city.
G. Premises Kept Free Of Garbage, Other Waste: The premises upon which any oil, gas or disposal well is drilled, operated or maintained shall be kept free of all accumulations of rubbish, litter, unused equipment or materials, excess rotary mud, saltwater, waste oil or oil byproducts and other waste, insofar as the same may be reasonably done in the conduct of operations covered by this chapter.
H. Safety Equipment, Devices And Methods: Approved equipment, standard devices and ordinary methods such as are commonly known and used in the oil and gas drilling and producing industry for the safety and protection of property from damage due to drilling and operating activities shall be used at all locations within the city. Failure on the part of any owner, driller or operator to utilize such equipment, devices or methods shall be the basis for injunction to the penalties therefor otherwise provided therein.
I. Surface Casing; Inspection: At least seven hundred fifty feet (750') of surface casing shall be set in each well after notification of intention to do so has been given the Oklahoma corporation commission, whose representative shall be entitled to inspect the installation thereof and direct the type and amount of cement to be used in cementing the same in the hole.
J. Mastergate: All drilling wells shall be equipped with a mastergate, or its equivalent, adequate blowout preventers, flow lines and valves commensurate with the working pressures involved.
K. Drilling Rig Near Lake: That part of the drilling rig adjacent to or facing any lake and situated within one-half (1/2) mile of the normal elevation thereof shall be covered with canvas, sheet metal or other suitable material at all times during drilling operations.
L. Production Casing: Production casing of a size with not less than a four and one-half inch (41/2") outside diameter, in good condition, shall be set no higher than the top of the producing formation and cemented with a sufficient amount of cement to obtain a maximum of five hundred feet (500') of annular fillup above the casing. All of such production casing shall be tested by pressure methods for either drilling the cement plug or perforating, if the cement is not drilled.
M. Completion Of Flowing Well: Upon completion of any flowing well, the wellhead equipment shall have, on the tubing, at least one master valve plus a flow valve, and a valve on the casing annulus. All wells shall be equipped with flow tubing of a size at least two inches (2") inside diameter extending not less than fifty feet (50') from the top of the lowest producing formation.
N. Disposal Wells: All disposal wells shall be equipped with at least two inch (2") inside diameter tubing set on a packer and a pressure gauge shall be installed on the casing annulus at all times. (1991 Code § 14-20)
