Dept. of Natursi Risoureas <br /> ATTENTION: Candace M. Thompson <br /> RE: Sedimentation Ponds Inspection, January 85 <br /> GENTLEMEN: <br /> On January 28 , 29 and 30 an inspection was made of all <br /> sedimentation ponds located within Mid Continent Resources Coal <br /> Basin mining area and Carbondale loadout area. The inspection <br /> was performed by Wesley Huff , Hydrologist and Tom Johansen, <br /> P .E . , both experienced in ponds construction, maintenance and <br /> inspection. <br /> The purpose of the inspection was to ensure that the structures <br /> were stable and hazard-free and to satisfy the requirements <br /> of Rules 4 .05 .E (11) (c) and 4 . 05 .9 (10) (b) of the Colorado Mined <br /> Land Reclamation Division. The inspection consisted of a visual <br /> examination of embankments , spillways and outlets; estimates <br /> of water and sediment levels and measurement of discharge volume. <br /> During the time of inspection a heavy blanket of snow, <br /> ranging from 1/12 to 6 feet in thickness , covered the ground <br /> surfaces making a thorough examination impossible. Nos 4 and <br /> 5 Mines are temporarily closed and unmaintained access roads <br /> prohibited pond inspections in these areas. Several ponds had <br /> to be visibly examined from a distant roadway. A walkaround <br /> reconnaissance of embankments and spillways were made wherever <br /> possible. Water levels were , in most cases estimated, based <br /> on observations and knowledge of conditions existing during <br /> the fall season. Sedimentation levels were estimated based <br /> on last cleanout date and knowledge of seasonal inflow. The <br /> flow from two ponds , known to be discharging , were measured <br /> and samples were taken. <br /> There are a total of 34 registered ponds within the Coal <br /> Basin sedimentation control area and pond , by the Carbondale <br /> loadout dock. The attached table summarizes the status of each <br /> at the time of inspection. <br />
