Peabody Sage Creek Mine <br />SL -3 Phase III Bond Release Request <br />July 2014 <br />three. There are three spoil wells above Spoil Spring 3: SSP59, 60, and 61. Well SSP61 is sampled <br />for water quality; only water level data is being collected at the other two. All seven spoil wells <br />will be removed after CDRMS approval of this bond release application. <br />Four bedrock wells were drilled by the USGS in 1987 upstream of Pond 004. They are: 1) Well <br />CL2 (30 feet deep, completed in the Lennox coal), 2) Well Cl2 (70 feet deep, completed in the <br />Lennox /Wadge interburden), 3) CW2 (90 feet deep, completed in the Wadge coal, and 4) Well <br />CU2 (122 feet deep, completed in the Wadge underburden). All wells are two inch diameter PVC, <br />and all four are normally flowing. All four wells are capped and pressurized with nitrogen gas to <br />prevent freezing in the winter. <br />Four bedrock wells were drilled by the USGS in 1987 downstream of Spoil Spring 4 (Spring <br />Creek area that eventually flows into Pond 002). They are: 1) Well SL2 (58 feet deep, completed <br />in the Lennox coal), 2) Well SI2 (80 feet deep, completed in the Lennox /Wadge interburden), 3) <br />SW2 (98 feet deep, completed in the Wadge coal, and 4) and Well SU4 (105 feet deep, completed <br />in the Wadge underburden). All wells are two inch diameter PVC (except for SU4 which is four <br />inch diameter). All four are normally flowing but are capped and pressurized with nitrogen gas to <br />prevent freezing in the winter. <br />Water quality and completion information for these eight USGS wells may be found in the USGS <br />Open File Report 92 -122; and USGS Water - Resources Investigation Reports 92 -4067 and 92- <br />4187. These wells were apparently last sampled by the USGS in 1989. These wells will be <br />removed using well abandonment procedures approved by the CDRMS after approval of this <br />bond release application. <br />The drainage channels and stock ponds that will remain in the Phase III bond release area are <br />those that have been previously approved for permanent retention in TR -37 (2006) and PR -2 <br />(2010) for the Seneca II Mine and are shown on Map 2.05AM1 (2010) of the PSCM permit. <br />Exhibit 13 -2A (updated in 2009) in the Seneca II Mine permit, also illustrates the approved <br />permanent features. These permanent features are shown on Map 2 accompanying this <br />document. Pond 004 which is adjacent to but not included in this Phase III bond release was <br />34 <br />
