(5.8)
"In situ mining" means the in-place development or extraction of a mineral by means other than open mining or underground mining.
(6)
(a)
"Life of the mine" means that a permit granted pursuant to section
34-32-110
or
34-32-115
may continue in effect as long as:
(I)
An operator continues to engage in the extraction of minerals and complies with the provisions of this article;
(II)
Mineral reserves are shown by the operator to remain in the mining operation and the operator plans to, or does, temporarily cease production for one hundred eighty days or more if he files a notice thereof with the board stating the reasons for nonproduction, a plan for the resumption thereof, and the measures taken to comply with reclamation and other necessary activities as established by the board to maintain the mine in a nonproducing state. The requirement of a notice of temporary cessation shall not apply to operators who resume operating within one year and have included, in their permit applications, a statement that the affected lands are to be used for less than one hundred eighty days per year.
(III)
Production is resumed within five years of the date production ended, or the operator files a report requesting an extension of the period of temporary cessation of production with the board stating the reasons for the continuation of nonproduction and those factors necessary to, and his plans for, resumption of production. In no case shall temporary cessation of production be continued for more than ten years without terminating the operation and fully complying with the reclamation requirements of this article.
(IV)
The board does not take action to declare termination of the life of the mine, which action shall require a sixty-day notice to the operator alleging a violation of, or that inadequate reasons are provided in an operator's report under subparagraph (I), (II), or (III) of this paragraph (a). In such cases, the board shall provide a reasonable opportunity for the operator to meet with the board to present the full case and further provide reasonable time for the operator to bring violations into compliance.
(b)
"Life of the mine" includes that period of time after cessation of production necessary to complete reclamation of disturbed lands as required by the board and this article, until such time as the board releases, in writing, the operator from further reclamation obligations regarding the affected land, declares the operation terminated, and releases all applicable performance and financial warranties.
(7)
"Mineral" means an inanimate constituent of the earth in a solid, liquid, or gaseous state which, when extracted from the earth, is useable in its natural form or is capable of conversion into a useable form as a metal, a metallic compound, a chemical, an energy source, or a raw material for manufacturing or construction material. For the purposes of this article, this definition does not include coal, surface or subsurface water, geothermal resources, or natural oil and gas together with other chemicals recovered therewith, but does include oil shale.
