b.Surface Water Effects and Mitigation <br /> Drainage and sediment control measures implemented by the applicant are <br /> sufficient to ensure that the quality of water downstream from the site is <br /> not impacted. The only impact on water quantity is the consumptive use <br /> of approximately 6 acre-feet per year during the operational life of the <br /> Loadout. <br /> The Terror Creek Loadout withdraws water from two sources. Water for <br /> dust suppression is supplied by senior water rights from the Deer Trail <br /> Ditch. The ditch withdraws water from Hubbard Creek. Use averaged <br /> 5,000 gallons per day (5.6 acre-feet/year). Previously, this water was used <br /> to irrigate orchards where the loadout is now located. A domestic well <br /> which supplies about 450 gallons per day (0.5 acre-feet/year) was used for <br /> domestic use at the Loadout office and bathhouse. Total consumption at <br /> the Loadout amounted to 0.002% of the North Fork's mean annual yield at <br /> Somerset. This amount of consumption is considered by the Division to <br /> be insignificant. <br /> 3. Summary and Findings <br /> The Division has examined the probable hydrologic consequence due to <br /> mining operations for groundwater and surface water systems at the Terror <br /> Creek Loadout. The operator has taken the necessary measures to ensure that <br /> mining operations will not affect the hydrologic regime (2.07.6(2)(c)). <br /> IV. Topsoil <br /> A. Baseline soils information can be found in Section 2.04.9 of the PAP. Map 3 of the <br /> PAP shows the locations of the soil mapping units. The topsoil salvage and <br /> redistribution plan can be found in Section 2.05 of the PAP. Map 8 of the PAP <br /> details the Topsoil Handling Plan and contains the locations of the topsoil <br /> stockpiles. <br /> Prior to construction of the loadout facility, topsoil was removed and stockpiled. <br /> There are two topsoil stockpile locations. A large pile is located on the west side <br /> of the permit area, and a smaller pile is located on the east side of the permit area, <br /> near the county road. <br /> - 16 - <br />
