The site is located approximately 10 miles south and 5 miles west <br />of Hall Station, Colorado. The pit is situated such that it straddles a portion of Pond <br />Creek with part of the active portion of the pit in the actual creek chand~el. The surrounding <br />area is gently rolling, shortgrass, rangeland typical to Eastern Colorado. <br />The site was recently amended to expand it from approximately 3 acres tp 9.9 acres. There <br />was a pre-law disturbance adjacent to the current disturbance and to aNoid confusion, the <br />permit boundaries were expanded to incorporate the pre-law area along with the current <br />disturbed area, as well as additional undisturbed area. All of the disturbances, pre-law and <br />current, are now well within the permit boundaries. These boundaries were clearly marked by <br />t-posts, however, the posts did not seem to be properly aligned with the~map representation. <br />Therefore, the site was field measured using a standard Trimble GPS unit. This information <br />was then downloaded and corrected to develop the attached map. As selen on the map, the <br />boundaries are not quite square, thereby, causing the actual field site to be less than 9.9 <br />acres. Therefore, this is being cited as a problem on page three of this; report along with <br />appropriate corrective actions. <br />In addition, the last map that was submitted by Lincoln County (dated 2~a/2000) showed the <br />limit of disturbance as mostly being on the north side of the active channel, however, based <br />on this site visit, it appears that at least a portion of the channel ]has been disturbed. <br />Also, for 110 permits, the permit area and the affected area are consideried to be analogous. <br />Therefore, the operator may want to revise their map to allow for disturbance throughout <br />their entire permitted area while specifying the pit location, the product and topsoil <br />stockpiles, the haul road, etc. <br />Another item that can be removed from this map is the sediment control dam in the southeast <br />corner of the permit area. Based on this inspection, it appeared that th'ie active portion of <br />the channel actually swings to the north in a typical meander common to t2~ese drainages. As <br />a result, the actual exit point for drainage off of this site would be somewhere near the <br />product stockpile. If a dike were needed that would be the location for its construction. <br />However, given the size and depth of the pit and its location, any creek flow will be <br />intercepted by the pit prior to leaving the site, and the pit will ther@fore function as a <br />large sediment basin. As a result, the inclusion of a sediment control dam across the <br />channel is an extra precautionary measure that is not needed at this time. Since the <br />application has already been approved, the changes to the map will need to be made via a <br />technical revision. This is also being cited as a problem on page three along with <br />corrective actions and dates. <br />This concluded the inspection. <br />I & E Contact Address cc: Jim Stevens <br />^ CE <br />NAME Pete Aragon ^ BL <br />OPERATOR Lincoln County ^ FS <br />STREET P.O.
