Ohio Revised Code Title XV. Conservation of Natural Resources § 1513.075

(A) As used in this section:

(B) For purposes of the determination of the chief of the division of mineral resources management regarding whether to approve an application for a permit for a coal mining operation based on criteria established in divisions (E)(2)(a) and (c) of section 1513.07 of the Revised Code and related performance standards established in division (A)(10) of section 1513.16 of the Revised Code, the potential acidity and the neutralization potential of the rock strata that would be disturbed under the permit may be calculated in accordance with this section.

(C) The measurement of potential acidity may be based on laboratory analyses of the sulfur content of the coal and overburden to be disturbed by mining. If the results of test borings or core samplings include laboratory analyses of the pyritic form of sulfur, the applicant may base the calculation of the potential acidity for the area on the pyritic sulfur content of the coal and overburden to be disturbed by mining rather than on the total sulfur content.

(D) The tons of rock in the area represented by each core hole resulting from test boring or core sampling may be estimated and used to calculate the tons of potential acidity and tons of neutralization potential for each rock stratum. The sum of those values across the proposed permit area may be used to calculate the site's overall neutralization potential and potential acidity.

(E) The proposed permit area may not be considered to have the potential to create acid or other toxic mine drainage if either of the following applies:
