(c) In any determination or proceeding under this section, it shall be presumed that an underground mine operator is responsible for the contamination, diminution or interruption of a water supply that is within an area above the mine determined by projecting a thirty-five degree angle from the vertical from the outside of any coal removal area. The mine operator may successfully rebut the presumption by affirmatively proving that access was denied to the property on which the supply is located to conduct premining and postmining surveys of the quality and quantity of the supply, that the mine operator thereafter served notice upon the landowner by certified mail or personal service, which notice identified the rights established by sections 5.1 and 5.3 and this section¹ that access had been denied and the landowner failed to provide or authorize access within ten days after receipt thereof.

(d) Unless the presumption contained in subsection (c) applies, a landowner, the department or any affected user asserting contamination, diminution or interruption shall have the burden to affirmatively prove that underground mining activity caused the contamination, diminution or interruption. Wherever a mine operator, upon request, has been denied access to conduct a premining survey and the mine operator thereafter served notice upon the landowner by certified mail or personal service, which notice identified the rights established by sections 5.1 and 5.3 and this section was denied access and the landowner failed to provide or authorize access within ten days after receipt thereof, then such affirmative proof shall include premining baseline data, provided by the landowner or the department, relative to the affected water supply.

(e) A mine operator shall be relieved of liability for affecting a public or private water supply by contamination, diminution or interruption by affirmatively proving one of the following defenses:

(f) Any mine operator who obtains water samples in a premining or postmining survey shall utilize a certified laboratory to analyze such samples and shall submit copies of the results of such analysis, as well as the results of any quantitative analysis, to the department and to the landowner within thirty days of their receipt. Nothing contained herein shall be construed as prohibiting a landowner or water user from utilizing an independent certified laboratory to sample and analyze the water supply.

(g) If an affected water supply is not restored or reestablished or a permanent alternate source is not provided within three years, the mine operator may be relieved of further responsibility by entering into a written agreement providing compensation acceptable to the landowner. If no agreement is reached, the mine operator, at the option of the landowner, shall:

(h) Prior to entering into an agreement with the mine operator pursuant to subsection (g), the landowner may submit a written request to the department asking that the department review the operator's finding that an affected water supply cannot reasonably be restored or that a permanent alternate source, as described in subsection (i), cannot reasonably be provided. The department shall provide its opinion to the landowner within sixty days of receiving the landowner's request. The department's opinion shall be advisory only, including for purposes of assisting the landowner in selecting the optional compensation authorized under subsection (g). The department's opinion shall not prevent the landowner from entering into an agreement with the mine operator pursuant to subsection (g), and such opinion shall not serve as the basis for any action by the department against the mine operator or create any cause of action in a third party, provided the operator otherwise complies with subsection (g).

(i) For purposes of this section, a permanent alternate source shall include any well, spring, municipal water supply system or other supply approved by the department, which is adequate in quantity, quality and of reasonable cost to serve the premining uses of the affected water supply.

(j) The department shall require an operator to describe how water supplies will be replaced. Nothing contained herein shall be construed as authorizing the department to require a mine operator to provide a replacement water supply prior to mining as a condition of securing a permit to conduct underground coal mining.

(k) Any landowner, water user or mine operator aggrieved by an order or determination of the department issued under this section shall have the right to appeal such order to the Environmental Hearing Board within thirty days of receipt of the order.
