The following requirements shall apply to the installation and operation of oil field recovery heaters.
(A) Each and every oil field recovery heater shall have a valid state permit to operate. It shall be equipped with and operated by safety controls which monitor certain essential operating conditions of the automatically controlled fire boiler; shut down the boiler automatically and require manual restart when any of the essential safety elements vary from certain prescribed limits. An emergency shut down switch shall be installed a minimum of 50 feet from the oil field recovery heater and shall be identified as such by a sign bearing letters not less than three inches in height.
(B) The following distances shall separate oil field recovery heaters from residential, commercial and public assemblage buildings:
(1) An oil or gas fired recovery heater shall be 300 feet distant. If it is enclosed by a six foot high and six inch wide block wall, the distance may be reduced to 50 feet;
(2) All oil field recovery heaters shall be located not less than 50 feet from any oil storage tank, well head or public right-of-way.
(C) (1) If the Fire Chief or his or her duly authorized representative so requires, every steam boiler located within 100 feet of an oil well or oil storage tank shall be equipped with an emergency quick acting valve so located as to complete shut off all fuel feed lines to each and every boiler. The location may be required outside the retaining wall. The valve shall be located not more than two feet from the valve controlling the stream or waterline to the fire box and shall have a metal tag not less than three by six inches attached thereto upon which shall be printed "Emergency Valve to Boilers (Fuel Line)."
(2) All lines used to furnish fuel to boilers or for the agitation of petroleum products within tanks, holders or containers shall have installed thereon a positive shutoff valve at or near the point of entry to the leasehold or at another suitable location designated by the Fire Chief or his or her duly authorized representative. The valve shall have a metal tag not less than three by six inches attached thereto upon which there shall be printed "Emergency Heater Fuel Valve Line" and the name or number of the leasehold and the name of the operator.
(D) Where an oil field recovery heater is operated within an area occupied by residential structures, the heater shall be shielded with a fire-resistant, sound-deadening material so that the sound level at the nearest residence can be maintained at the average ambient level existing when such heater is not in operation; provided, however, the fire resistant sound- deadening shield shall not be required if the residential ambient level mentioned in this section can be maintained by other means.
(E) Heaters being operated in any residential zone shall be completely fenced, including the well head, with a six foot high chain link or block wall fence complete with two self-closing gates installed on opposite sides of the enclosure. Steam lines from the heater to the well head shall be buried to a depth of one foot or in lieu thereof covered and/or wrapped with a minimum of one inch approved asbestos pipe insulation.
(F) (1) Prior to installing and operating an oil field recovery heater, an application for a permit to do so shall be filed with the Secretary who, prior to issuing a permit to install, shall inspect the proposed site and specify the location, setup and/or standards of the heater, piping, head installation, valves, sound-deadening (if required) and other equipment. Upon completion of such an installation, the Secretary shall inspect it, and if he or she approves such, he or she shall issue a permit to operate the heater pursuant to all provisions of this title applicable to such operation.
(2) Approval by the Secretary does not relieve the applicant of the responsibility of securing additional city and state permits which are required by other provisions of state and city law.
(G) The permit to operate an oil field recovery heater shall show the name of the owner and/or operator of the heater, the well name, the name of the owner and/or operator of the well and two telephone numbers to be called for purposes of emergency related thereto. Names and telephone numbers of individuals available in case of emergency shall be posted by the permittee in a conspicuous place at the drill site.
(H) If in the opinion of the Secretary the proposed location of an oil field recovery heater is deemed to be hazardous or dangerous to life, limb or property, a permit may be denied. The owner or operator may appeal the denial pursuant to the procedures set forth in § 14.32.070.
