It shall be unlawful and an offense for any person or corporation to do or permit any of the following, and the same are hereby declared to be a public nuisance.
1. Earthen slush pits shall not be constructed, maintained or used by any person or corporation at any location within the city. All waste oil, salt water, liquid with oil content, gasoline or other waste produced in connection with the drilling, testing, cleaning, swabbing, re-working or operating of any oil, gas or disposal well shall be captured and retained in steel tanks or vessels and transported from the premises to a disposal facility. In no event shall any of such substances be permitted to escape from the premises owned, leased or controlled by the persons 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 gully, stream or tributary within the city. Plastic liners may be required, at the discretion of a majority of the City Council.
2. Earthen reserve pits, as herein defined, which contain no salt water, oil, oil derivatives, caustics, acids or other deleterious substances harmful to soil, vegetation or injurious to animal or human life, shall be allowed to be constructed or used in connection with the drilling, swabbing, cleaning out or re-working of oil or gas wells within the city, and the contents thereof need not be transported from the premises to a disposal facility, if the same are leveled and the surface of the ground restored as nearly as possible to its original condition within 90 days after completion of said drilling, swabbing, cleanout or re-working operations.
3. 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 Christmas tree 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.
4. 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 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 100 feet to a dwelling or business structure, street or highway within the city.
5. 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 250 feet of any dwelling or business structure within the city.
6. 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 250 feet of any church, school or hospital building within the city.
7. Premises upon which any oil, gas or disposal wells are drilled, operated or maintained shall be kept free of all accumulations of rubbish, litter, unused equipment or materials, excess rotary mud, salt water, waste oil or oil by-products and other waste, insofar as the same may be reasonably done in the conduct of operations covered by this chapter.
8. 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 thereof by the city or any person affected thereby, in addition to the penalties therefor otherwise provided therein.
9. At least 750 feet of surface casing shall be set in each well after notifications of intention to do so have been given the State 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.
10. 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.
11. That part of the drilling rig adjacent to or facing any lake and situated within one-half mile of the normal elevation thereof shall be covered with canvas, sheet metal or other suitable material at all times during drilling operations.
12. Production casing of a size with not less than a four and one-half inch 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 500 feet 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.
13. 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 inside diameter extending not less than 50 feet from the top of the lowest producing formation.
14. All disposal wells shall be equipped with at least two inch inside diameter tubing set on a packer and a pressure gauge shall be installed on the casing annulus at all times.
