R 324.1123 Incinerators and flares; equipment and design requirements; additional requirements.

Rule 1123. (1) A permittee of a well shall ensure that an incinerator or flare installed under R 324.1117, R 324.1122, or R 324.1124 is designed and equipped to prevent the release of unburned gas to the atmosphere. If the daily volume of gas handled by the incinerator or flare contains 28 pounds or more of hydrogen sulfide, then a permittee shall ensure that the incinerator or flare is equipped with a mechanism that operates upon failure of the pilot light to shut off the flow of fluid from the wellhead. (2) A permittee of a well shall ensure that an incinerator or flare required by R 324.1122 is fenced. A fence shall be located not less than 20 feet from the base of the incinerator or flare. A permittee of a well shall ensure that warning signs that have the word "Danger" or "Caution" followed by the words "Poison Gas" are posted on all sides of the fence. If the supervisor or authorized representative of the supervisor finds that a threat to the public safety still exists due to emissions of the incinerator or flare, then fencing other than that specified in R 324.102(p) may be required. (3) If the supervisor or authorized representative of the supervisor finds that a threat to the public health or safety exists due to the emission of sulfur-bearing gasses or vapors, then a flare stack or incinerator stack that is more than 20 feet high, as specified in R 324.1101(f) and (h), may be required.
