NR 270.001NR 270.001 Purpose. The purpose of this chapter is to establish effluent limitations and standards of performance for discharges of process wastes from the ore mining and dressing category of point sources and its subcategories. NR 270.001 HistoryHistory: Cr. Register, October, 1986, No. 370, eff. 11-1-86. NR 270.0015NR 270.0015 Applicability. Abbreviations and methods of analysis set forth in 40 CFR Part 401 shall apply to this chapter except as provided in ss. NR 270.002 and 270.003. The general provisions and definitions apply to all subcategories of this chapter unless otherwise noted. NR 270.0015 HistoryHistory: Cr. Register, October, 1986, No. 370, eff. 11-1-86. NR 270.002NR 270.002 General definitions. In addition to the definitions set forth in 40 CFR Part 401, the following definitions apply to this chapter: NR 270.002(1)(1) “Active mining area” is a place where work or other activity related to the extraction, removal, or recovery of metal ore is being conducted, except, with respect to surface mines, any area of land on or in which grading has been completed to return the earth to desired contour and reclamation work has begun. NR 270.002(2)(2) “Annual precipitation” and “annual evaporation” are the mean annual precipitation and mean annual lake evaporation, respectively, as established by the U.S. department of commerce, environmental science services administration, environmental data services, or equivalent regional rainfall and evaporation data. NR 270.002(3)(3) “Appropriate treatment of the recycle water” includes, but is not limited to pH adjustment, settling and pH adjustment, settling, and mixed media filtration. NR 270.002(4)(4) “Existing source” means any source that is not a new source. NR 270.002(5)(5) “Groundwater infiltration” means that water which enters the treatment facility as a result of the interception of natural springs, aquifers, or run-off which percolates into the ground and seeps into the treatment facility’s tailings pond or wastewater holding facility and that cannot be diverted by ditching or grouting the tailings pond or wastewater holding facility. NR 270.002(6)(6) “In-situ leach methods” means the processes involving the purposeful introduction of suitable leaching solutions into a uranium ore body to dissolve the valuable minerals in place and the purposeful leaching of uranium ore in a static or semistatic condition either by gravity through an open pile, or by flooding a confined ore pile. It does not include the natural dissolution of uranium by groundwaters, the incidental leaching of uranium by mine drainage, nor the rehabilitation of aquifers and the monitoring of these aquifers. NR 270.002(7)(7) “Mill” means a preparation facility within which the metal ore is cleaned, concentrated, or otherwise processed before it is shipped to the customer, refiner, smelter, or manufacturer. A mill includes all ancillary operations and structures necessary to clean, concentrate, or otherwise process metal ore, such as ore and gangue storage areas and loading facilities. NR 270.002(8)(8) “Mine” is an active mining area, including all land and property placed under, or above the surface of such land, used in or resulting from the work of extracting metal ore or minerals from their natural deposits by any means or method, including secondary recovery of metal ore from refuse or other storage piles, wastes, or rock dumps and mill tailings derived from the mining, cleaning or concentration of metal ores. NR 270.002(9)(9) “Mine drainage” means any water drained, pumped, or siphoned from a mine.
