Such determination may be based upon <br />acceptable accelerated weathering and leaching tests of a representative sample of the <br />overburden, waste rock, miIl tailings, or other mined, placed, disposed, or stockpiled <br />material In determining whether a potential for acid mine drainage generation exists, . <br />the Office will consider natural pre-mining acidity and metals occurrence in bedrock, <br />soil, groundwater and surface water where such information is available to the Office: <br />Mined and stockpiled material does not include ore or other mined product that is or <br />will be processed within one hundred eighty (180) days of being stockpiled and <br />removed from the permit azea. .However, the azea affected by such stockpiled <br />material may require the appropriate measures pursuant to Rules 3, 6 and 7, to <br />prevent off-site impacts due to drainage or leaching, and for reclamation of the <br />affected stockpile area. <br />(3) `Activity" for the purpose of protecting groundwater quality, means <br />any mining, milling, storing, disposing, or processing operations, or any reclamation <br />operation or process that may discharge or cause dischazge of pollutants to <br />groundwaters. <br />ios (4) "Affected Land" means the surface of an azea within the state where <br />a mining operation is being or wiIl be conducted; which surface is disturbed as a result <br />of such operation. Affected lands include but shall not be limited to private ways, <br />roads, except those roads excluded pursuant to this Subsection, 1.1(4), and railroad <br />lines appurtenant to any such azea; land excavations; prospecting sites; dn71 sites or <br />workings; refuse batiks or spoil piles; evaporation or settling ponds; leaching dumps; <br />placer areas; tailings ponds or dumps; work, pazking, storage or waste dischazge <br />
