- ~-CONTINENT RESOURCES, INC', <br />P.O. BO\ 500 <br />CARBONDALE. COLORADO 81623 <br />PLAN AND DESIGNS FOR THE DIVERSION OF UPLAND FLOW <br />AWAY FROM THE MD-CONTINENT LIMESTONE QUARRY, PERMIT M-82-121 <br />SE-1/4 SEC. 36, T. 5 S., R. 89 W., GARFIELD COUNTY, COLORADO <br />This plan and the accompanying designs are submitted in <br />accordance with the Corrective Action requirements of Notice <br />of Violation M-92-024, issued by the Mined Land Reclamation <br />Board, Colorado Department of Natural Resources, on <br />April 24, 1992. <br />The Mid-Continent Limestone Quarry ("quarry"), owned by Mid- <br />Continent Resources, Inc. (MCR) and operated by Pitkin Iron <br />Corporation (PICO), is located in a mountainside ravine <br />north of Glenwood Springs, Colorado. Three ephemeral <br />drainages pass through the quarry operating area, combining <br />into a single unnamed drainage just below the quarry; at the <br />southwest edge of the mineral lease (see Map C-la, Mining <br />Plan, Permit M-82-121, revised per this plan and included <br />herewith), this drainage intersects a public road (Transfer <br />Trail Road, White River National Forest Road 602 and a <br />Glenwood Springs city road), and for a distance of <br />approximatly 0.75 miles, to the intersection of the Transfer <br />Trail Road and Traver Trail (paved access road to the Oasis <br />Creek subdivision), this road is in the "streambed" of the <br />subject drainage. Flowing water in the drainages above this <br />point is extremely unusual and occurs only as the result of <br />major summer thunderstorms or unusually rapid snowmelt. <br />Runoff is more common on the road, both above and below the <br />drainage intercept. <br />The three ephemeral drainages mentioned above are <br />hereinafter referred to as Area I, to the west and at 137 <br />acres by far the largest; Area II, in the middle and the <br />smallest, at 59 acres; and Area III, to the east, 64 acres. <br />These areas are shown on the location map, next page. MCR <br />proposes to divert the east and west drainages around the <br />quarry disturbed area by means of perimeter ditches designed <br />to carry the peak discharge of a 10-year 24-hour storm. MCR <br />proposes to direct the middle drainage and other drainage <br />within the quarry perimeter to the production and fines <br />
