Species Variety #/Acre PLS <br /> Drilled, rate doubled <br /> if broadcast <br />western wheatgrass Rosana or Arriba 3.3 <br />fairway crested Ephraim 10.0 <br />wheatgrass <br />Total PLS/acre 13.3 <br />Mulch: Seeded areas will be mulched. Grass hay or cereal grain straw that is weed free <br />will be used. Approximately 2 tons of mulch per acre will be applied to seeded areas. <br />The mulch will be anchored with either a commercial product or mechanically anchored. <br />If anchored mechanically, the mulch will be crimped 2-3 inches into the soil and care will <br />be taken to ensure that the mulch is not severed, to the extent practicable. <br />Methods of weed control: If noxious weeds invade the site, a weed control program will <br />be implemented as soon as possible. The County weed control specialists will be <br />contacted and recommendations followed. <br />Delays to the reve~etation process on selected areas: It is understood by COAG that <br />planting required for reclamation may be delayed, through the period of use related to the <br />prospecting activities. All applicable industry stabilization standards for such areas will <br />be used. COAG is aware that no planting is required on the following areas: <br />a) On lands proposed for future mining. <br />b) On any affected land so long as the chemical and physical characteristics of <br />the surface and immediately underlying materials of such affected land are toxic, <br />deficient in plant nutrients, or composed of sand, gravel, and cannot feasibly be remedied <br />by chemical treatment, fertilization, replacement of overburden or like measures. <br />2. Impacts to the hydrologic balance will be minimal. "No major aquifers are known to <br />occur beneath the site. Bedrock is a Precambrian age metasedimentary gneiss. When <br />undisturbed, this deposit likely would be relatively low yielding aquifer with permeability <br />(water flow) confined to fracture zones. Because of construction of the Argo Tunnel many <br />years ago, most of the bedrock at and near the FCM (Franklin Consolidated Mine), (The site <br />of the proposed NOI.) has been drained." (From the Franklin Consolidated Mine Regular <br />(112) permit amendment dated September 9,1983 and filed with the Division.) Given the <br />above description and that only bulk sampling will occur during the prospecting activity, <br />impacts to ground water should be minimal. <br />
