In order for the Division to approve the surface water monitoring plan <br />described in the application on pages 780-109aaa and bbb, additional <br />clarification is required. The following stipulation is necessary for <br />permit approval: <br />KERR COAL IS DIRECTED TO SUBMIT A TIMETABLE FOR ItfITIA TING ALL ASPECTS <br />OF THE FlONITOP.ING PROGRAM DESCRIBED ON PAGES 780-1 U9aaa AND bbb. f/E <br />REQUIRE THIS INFORMATION TO BE SUBMITTED BY SEPTEMBER J0, 1981. IN <br />ADDITION XERR COAL IS REQUIRED TO SUBMIT TO THE DIVISION A YEARLY REPORT <br />ON THE PROGRESS OF FfONITORZNC :/H ICH INCLUDES ALL DATA COLLECTED FOR <br />THAT YEAR AND A DISCUSSION ON ANY CONCLUSIONS f/H IC'H CAN BE DRA[/t! FROM <br />THE DATA. KERR COAL SHOULD [JORK CLOSELY {JI TH THE DIVISION AS TlIE PROGRAM <br />IS DEVELOPED AND FIODIFY TO INSURE THAT COMPREHENSIVE BUT EFFICIENT <br />MONITORING WILL TAKE PLACE. <br />J. The data submitted in Table l0 does not support the conclusion that coal <br />dust does not affect water quality in the swamp adjacent to the tipple. <br />In order to clarify this issue, the following stipulation is necessary: <br />TlfE APPLICANT S1f0ULD RC-ANALYZE AND RE-SUBMIT TffE E.YISTING DAT,7 IN TAIILE 10 <br />TO CONSIDER THE EFFECTS OF COAL DUST ON WATER QUALITY IN TffE ADJACENT <br />S[/AF1P, ~ OR ALTERNATIVELY Tf1E APPLICANT SHOULD REDES IGff THE WATER MOtJZTORING <br />PROGRAM AT THE TIPPLE TO COLLECT USABLE DATA. THIS INFORMATION SHOULD <br />BE SUBMITTED TO THE DIVISION NO LATER THAN APRIL 1, 1981. <br />VI. Hydrologic Balance: ,round 1•/a ter (2.04.5, 2.04.7, 2.05.3(4), 2.05.6(3), 4.05) <br />The Sudduth coal seam, underburden and overburden units of the open Pit No. J are <br />in hydrologic communication with the alluvium of Sudduth Draw. The bottom of <br />open Pi[ No. J will be 120 feet below the level of Sudduth Draw. The pit will be <br />dewatered during mining. These factors will produce an increase in groun~i water <br />gradient and ground water flow from Sudduth Draw towards the pit. The result will <br />be depletion of flow in Suddutff Draw. This depletion can be minimized by decreas- <br />ing the infiltration over tfle subcrop in Sudduth Draw. Two stock ponds, one upstream <br />and one over the subcrop, exist on Sudduth Draw. These ponds increase the amount <br />and the Sength of tine that surface waters can infiltrate the alluvium, as is evident <br />from the subirrigated area below the ponds. Water, which is allowed to infiltrate <br />through the ponds upstream and over the subcrop area, will be lost to beneficial <br />use in the immediate area ,ind dorm stream during and after Wining the northern <br />section of Pit f1o. 3. Water losses to the pit could he minimized by removing the <br />two ponds upstream and nvar the subcrop area. To resolve this roncern, [he follow- <br />ing Stipulation is necnssa nf: <br />KERR COAL COh1PANY IS REQUIRED TO SUBh1IT A PLAN TO TffIS DIVISION NO L.1 TER TffAN <br />S c'PTEidBER 30, 1981, FOR F1IN I11I2ING T1fE DEPLETION OF [/A TER FROM SUDDUTfI DP.A[J <br />CAUSED BY GROUND f/A TER IN FLO[/S DISCHARGING INTO PIT NO. J. ANY MEASURES WIIICN TIlE <br />DIVISION DETERMINES TO BE NECESSARY TO ALLEVIATE TN IS POTENTIAL PRODLEM SIfALL D~E <br />IMPLEMENTED PRIOR TO MINING ADJACENT TO SUDUT!! DRAW. <br />Water nuality information has been requested by tf~e Division from the sprinc at <br />the old Sudduth dine. These analyses will provide actual water quality from an <br />area disturbed by mining, and will thus allow more •3ccurate predictions to be <br />m,ide of the impacts of Che proposed mining. Ohtaininq samples .`rom the Boring <br />may require the excavation of a shallow pit to facilitate sample cnllect[on. <br />
