TAH 16 <br />• PFD1'ECTIOH OF THE HYDROLOGIC T+a*a*n"w <br />Introduction <br />The coal handling and shipping activities and eventual site reclamation activities that ere to ba <br />carried out at the Hayden Gulch Terminal, Inc. (HGP) Loadout Pacility have been designed to <br />,~; za disturbance tc the hydrologic balanw within the permit boundary and areas adjacent to <br />the facility. Activities associated with operating the facility that assure protection of ground <br />water, aurfaw water, stream buffer zones, water rights and alternative water supplies, and <br />alluvial valley floors era eddzeesed herein. The loadout facility operation and reclamation <br />activities, as well 88 monitoring and data reporting, have bean planned in acooxdanw with the <br />Probable Hydrologic Consequenwa (PHC) de~term ^~tion (Tab 15) and the analysis of baseline <br />hydrologic, geologic, and other pertinent infoxmatiw required in the permit application. <br />Refarenw t0 additioal tabs *'ega~+ , oomplate details of loadout facility and reclamation <br />operations that address aspects of the protactiw of the hydrologic belanw axe doc:mented in the <br />following sections when and where they are appropriate. <br />• Ground Water Protection <br />Operation of the HGT Loadout facility will not inwlve significant additional land disturbanw <br />within the permit boundary. Tha facility ie designed to m;,,:m: za the potential oP leakage to the <br />shallow aquifers of all materials flat may be used to operate or mainta in coal handling and <br />shipping equipment. Impacts to the localized shallow groundwater syat® fxnm stockpiled coal <br />leachate will be my (see Tab 15, o,.a,.tiie Hydrologic Conaequenwa). The loadout facility <br />well bB bacJcfilled and regraded, and ~'~ ~^'°tlw wrll be achleVed uelnq topsoil of suitable <br />teatOral and Ch8mlCal natnte t0 LeatOLB lOCallZed _w~Yv rates oomparablB LA undisturbed LetB9, <br />and to m +~^; ze a~ potential for degrading shallow ground water quality. Badc£illinq and <br />regrading methods, topsoil handling, reconditioning, end revegetation methodn era outlined in <br />Tabs 9 (soils), 18 (Back£illing and Grading), 19 (Soil Reconstruction) end 20 (Revegetation <br />Plan). Ae described in Tab 7, Hydrologic Description, the quality and quantity of the shallow <br />groundwater in the vicinity of the loadwt facility is not suitable for any present or potential <br />use, henw, the operative and eventual reclamation of the loadout facility rill not adversely <br />impact the local and regional groundwater system. <br />1 <br />• <br />
