Forest Service dater Resources <br />Dear Mr. Kingston, <br />To update and clarify Mountain Coal Company's (-MCC) 1986 agreement with the U. S. Forest <br />Service Paonia lager District (USFS) to monitor the USFS surface water resources that are <br />located above panels to be retreat irined (i.e., longwall rained or secondary recovery), T niet with <br />bike Ward at your office on February 07, 1995. Tn surrunary, MCC shall: <br />A Maintain Map 37 that contains the locations of the USFS surface water <br />resources (stock ponds) within the Test Elk Mine area of interest. MCC shall <br />contact the USFS at least annually for updated USFS surface water resource <br />information (i.e., asld ponds constructed or moved, etc.) If updated, a copy of Map <br />37 shall be submitted by revision application for incorporation into MCC's Permit <br />document. A current map shall also be included in Annual Hydrology Reports <br />(provided annually to the USFS.) <br />Monitor for effects of subsidence by visually inspecting (access permitting) <br />USFS surface water resources with plmried seasonal livestock use that are within <br />the surface area defined by the angle -of -draw from longwall rained areas and areas <br />of active secondary recovery. These inspelions shall typically be conducted <br />monthly during the grazing season only (unless changing conditions require a more <br />frequent or less frequent monitoring interval as determined by the District Ranger.) <br />This monitoring shall typically begin one year prior to planned retreat mining (for <br />baseline condition) and end after complete subsidence of the area [i.e., two <br />consecutive subsidence surveys with no measured movement not attributable to <br />natural forces (e.g., frost heave, sloughage, etc.)] MCC shall contact the USFS <br />each year to determine the areas and start and end dates (duration) of planned <br />seasonal livestock use. <br />e Promptly report to the USFS any subsidence "impacts" observed by MCC <br />inspection. MCC shall also promptly inspect (access permitting) a reported <br />rrirrtpact" to a `Fuse" by a grazing permitter, or USFS official. <br />
