713.12 PLUGGING REQUIREMENTS.
   (a)   All abandoned gas or oil wells must be plugged in a manner prescribed by the Ohio Division of Mines, State statutes and this chapter.
   (b)   In addition to requirements set forth by the Division of Mines, the following shall be required:
      (1)   All wells to be plugged which are located under parking lots, roads, streets or highway rights of way or other areas to be used for public purposes, shall be enclosed in a brick or masonry manhole fitted with a steel cover not less than thirty inches in diameter. Such cover shall be plainly marked, "Abandoned Gas Well" and shall be used for access for inspection of the well.
      (2)   All plugged wells must be vented by a vent pipe not less than two inches in diameter and of such height as prescribed by the Division of Mines, the State and the City Fire Chief and the City Director of Inspections. Such vent pipe shall have a drilled and tapped inspection hole with hole plug not less than one-half inch in diameter and not more than four feet above grade.
      (3)   It shall be the duty of any person, in the drilling of a well or the cleaning of an abandoned well preparatory to the plugging of such abandoned well, to provide for a drilling-in control gate, which shall be so constructed as to effectually cut off the flow of gas to the top of the well and which can be operated at a remote point from the well.
      (4)   All abandoned wells to be plugged must be cleaned out to a point approximately 100 feet below the top of the Niagara lime, then bridged solid and one or more lead plugs set and driven until all gas, oil and water are shut off, and then pressure cemented to within twenty feet of the existing eight inch casing. If the eight inch casing is not of sufficient quality and quantity, it should be removed and the ten-inch hole be reamed to the 200 foot level, and a like amount of good grade of eight inch casing be pressure cemented to the surface to make sure that the vent will be of a more permanent nature. In the event it is a shallow well, it should be treated in the usual manner and filled with prepared fire clay to the surface and vented.
