crag >, faults and fissures. The intersected ground waters are <br />collected in the workings and gravity drain from the mine at the <br />• American funnel Portal. At the surface the mine drainage is im- <br />pounded in a series of sedimentation basins to effect treatment in <br />compliance with federal and state permits issued for the discharge. <br />Upon treatment the mine water is discharged to Cement Creek at an <br />average flow rate of 1,200 GPM. Mine drainage collection and <br />treatment processes as described constitute the only water diversion <br />activity associated with mining operations. <br />Due to the totally underground nature of the mining operation, <br />no earthmoving or overburden displacement is associated with mine <br />activities. Methods employed for mine development and extraction <br />of ore from the Sunnyside Mine result in minimal impact to surface <br />lands and acreage affected by the operation is limited. The major <br />surface disturbance associated with the mine operation is the <br />acreage utilized for mine process support structures (i.e., dry <br />room, mechanics shop), mine equipment storage yards, and mine drain- <br />age treatment facilities which presently occupy //.5 acres at they . <br />American Tunnel Portal (see map Ie.). <br />Upon removal from the mine, the ore is loaded into haul trucks <br />(40 ton) and transported 9.0 miles by county road 110 to the Ma~~flower <br />MiiT for processing. The Mayflower Mill was origina]ly constructed <br />for processing ores removed from the Mayflower Mine, and began i~ro- <br />duction in 1930 under the ownership of the Shenandoah-Dives Mining <br />Company of Kansas City, Missouri. Initial milling capacity of the <br />facility was 350 tons per day. In 1934 milling production was in- <br />creased to 700 tons per day, and remained at that. level until 1953, <br />• when the mine and mill closed due to depressed metal market prices. <br />22. <br />
