(A) Electrical equipment. All electrical equipment used, installed or maintained within 50 feet of a drilling well and within 25 feet of a producing well, shall be installed and maintained in accordance with the Electrical Code of the city.
(B) Internal combustion engines, storage tanks, fired equipment and open flames. No internal combustion engine, storage tanks, boiler, fired equipment or open flames except welding supervised by the production foreman, drilling foreman, drilling engineer, drilling supervisors, or safety supervisors shall be located closer than 25 feet to a producing well nor closer than 100 feet to a drilling well. Internal combustion engines (and their fuel tanks) used in the drilling, production and servicing of oil wells are exempt from the above provisions. During drilling operations on a drill site of two acres or less in area where two or more wells are drilled and drilling and production equipment are located on such sites, the provisions in this division relating to distance of storage tanks may be altered at the discretion of the Building Inspector after consideration of the special features such as topographical conditions; nature of occupancy and proximity to buildings on adjoining property and height and character of construction of such buildings; capacity and construction of proposed tanks and character of liquids to be stored; degree of private fire protection to be provided, and facilities of the Fire Department to cope with flammable liquid fires.
(C) Muffling exhaust. The engines used in connection with the drilling of any oil well or in any production equipment of any oil well shall be equipped with an exhaust muffler to prevent excessive or unusual noise. Means shall be provided on all engines used during drilling operations to prevent the escape of flames, sparks, ignited carbon and soot.
(D) Flammable waste gases and vapors. Flammable waste gases or vapors escaping from a production drill site shall be burned or controlled to prevent hazardous concentrations reaching sources of ignition or otherwise endangering the area.
(1) Flares. Approved means of ignition shall be provided whenever hydrocarbon gases are released to the air through flares.
(2) Venting. Gases or vapors not burned may be discharged to the atmosphere at not less than 20 feet vertically above grade and not less than 25 feet horizontally from any source of ignition and at locations that do not create a hazard to the general area.
(E) Waste control of drill site.
(1) No person shall permit or cause to be permitted the discharge of any liquid containing crude petroleum or its products into or upon any street, public highway, drainage canal, or ditch, storm drain or flood-control channel.
(2) No person shall permit or cause to be permitted any oil, waste oil, refuse or waste material to be on the surface of the ground, under, around or near any oil well, pump, boiler, oil storage tank or building except within an oil sump, tank, catchment basin or skimming pond.
(3) All land within 25 feet of any oil well, flammable liquid tank or other appurtenance to any such well shall be at all times kept free and clear of dry weeds, grass, rubbish or other combustible debris. When this distance is not sufficient to provide reasonable fire safety, a greater distance may be required which shall not exceed the height of the derrick or greatest dimension of the tank.
(F) Smoking. No person shall smoke nor cause, permit or allow another person to smoke within 50 feet of any well, tank location, or any area contaminated by oil or waste gas.
(G) Fire control equipment. A minimum of two fire extinguishers shall be maintained at all oil well locations where drilling, servicing or repair work is being conducted. Each such extinguisher shall have a minimum classification of 20B as set forth in N.B.F.U. No. 10, “First Aid Fire Appliances,” in accordance with the Fire Code of the city. Fire control shall be as follows:
(1) Where flammable liquids are used or dispensed, first aid fire appliances shall be provided. The number and type of appliances shall be as provided in N.B.F.U. No. 10, N.F.P.A. No. 10, “Portable Fire Extinguishers.”
(2) Whenever flammable liquids are stored in containers, provision shall be made and maintained for the detection of leakage. Leaking containers shall be immediately removed or made tight.
(3) Access shall be provided by unobstructed aisles whereby first aid fire control apparatus may be brought to bear on any part of such flammable liquids storage.
(4) In buildings, rooms or other confined spaces in which flammable liquids are stored, no combustible waste materials shell be allowed to accumulate.
(5) Crankcase drainings and flammable liquids shall not be dumped into sewers, but shall be stored in tanks or tight drums outside of any building until removed from the premises.
