(A) Every operator of a coal mine who is required by sections 1563.03 to 1563.05 of the Revised Code, to file maps of such mine, shall cause to be shown on each of such maps, in addition to the boundary lines of each tract under which excavations are likely to be made during the ensuing year, as referred to in section 1563.03 of the Revised Code:
(C) Every operator of a coal mine who expects that any part of the boundary of such mine will, on a date after September 9, 1957, be extended beyond its location on such date to a point within two thousand linear feet of a well that is drilled through the horizon of such mine and into or through the stratum or strata of a gas storage reservoir within the boundary of such reservoir or within its protective area, shall send at least nine months' notice of such date and of the location of such well by registered mail to the operator of such reservoir, the division of mineral resources management, and the division of oil and gas resources management. If at the end of three years after the date stated in the notice by an operator of a coal mine to an operator of a storage reservoir as the date upon which part of the boundary of such coal mine is expected to be extended to a point within two thousand linear feet of such well, no part of such coal mine is so extended, the operator of such coal mine shall be liable to the operator of such storage reservoir for all expenses incurred by such reservoir operator in doing the plugging or reconditioning of such well as the reservoir operator is required to do in such cases as provided in section 1571.05 of the Revised Code.

If at the end of nine months after the date stated in the notice by an operator of a coal mine to an operator of a storage reservoir, the division of mineral resources management, and the division of oil and gas resources management, as the date upon which such coal mine operator intends to open such new mine, such new mine is not opened, the operator of such coal mine shall be liable to the operator of such storage reservoir for all expenses incurred by such reservoir operator in doing the plugging or reconditioning of such well as the reservoir operator is required to do in such cases as provided in section 1571.05 of the Revised Code, provided:
