Doc Date:12/11/2001 III IIIIIII+IIIII III <br />ass <br />' ~~4.8.6 Small Area Exemptions <br />i <br />Seven small area exemptions from constructing sediment dams have been granted to Trapper Mine by <br />the Colorado Mined Land Reclamation Division during the mine's life and are presented in this section. <br />Currently, no active small area exemptions (SAE) exist. Drainage from all haulroads passes through <br />sedimentation ponds prior to discharge from the permit area. <br />SAE 1 was an ammonium nitrate storage area (less than one acre in size) which is located in Buzzard <br />drainage below the settling ponds. This SAE was eliminated with Far East Buzzard pond wnstruction. <br />SAE 2 was removed from Trapper Mining's control as a result of the 1985 transfer of a portion of the D Pit <br />bonded area to Empire Energy. <br />SAE 3 consisted of the remnants of an old scoria stockpile. Much of the pile has been cleaned up and all <br />of the area associated with this former SAE drains into Elk sediment pond #1. <br />SAE 4 consisted of a topsoil stockpile which has been seeded to a perennial seed mix. The drainage <br />from this former area flows into the West Buzzard sedimentation pond system. <br />SAE 5 was a small topsoil stockpile (approximately 1.5 ac) constructed in West Pyeatt drainage, upstream <br />from the haul road crossing. This SAE was eliminated with West Pyeatt pond construction. <br />• SAE 6 was an electrical substation (< 1 acre) constructed in West Pyeatt drainage, upstream from the <br />haulroad crossing. This SAE was eliminated with West Pyeatt pond construction. <br />SAE 7 was issued in 1996 for topsoil stockpile D-77-1 by Minor Revision No. 147. SAE 7 was eliminated <br />by Minor Revision No. 180 which referenced the previously approved SL-2 Phase II Bond Release <br />Application (approved January 30, 2000) as the demonstration required by the Division showing that the <br />SAE 7 sediment control structures were no longer required to treat runoff from this area. <br />a~~ to®~' ~ ~,~ ~7 ~ 3 2~0~ <br /> <br />4-248 <br />APPrwed'----' <br />
