2. In order for the Division to approve the surface water monitoring plan
described in the application on pages 780-109aaa and bbb, additional
clarification is required. The following stipulation is necessary for
permit approval:
KERR COAL IS DIRECTED T7 SUBMIT A TIMETABLE FOR INITIATING ALL ASPECTS
OF THE FIONITOP.ING PROGRA,N DESCRIBED ON PAGES 790-109aaa AND bbb. !JE
REQUIRE TX ZS INFORMATIOfJ TO BE SUBMITTED BY SEPTE,NDER 30, 1981. IN
ADDITION KERR COAL ZS REQUIRED TO SUBMIT TO TXE DIVISION A YEARLY REPORT
ON THE PROGRESS OF MONITORING {JN ICJI INCLUDES ALL DATA COLLECTED FOR
THAT YEAR AND A DISCUSSION ON ANY CONCLUSIONS lJHIC'!f CAN BE DRAlJJJ FR0f1
THE DATA. XERR COAL SHOULD {JORK CLOSELY IJI Tlf THE DIVISION AS TILE PROGRAfi

MONITORING WILL TAKE PLACE.
3. The data submitted in Table 10 does not support the conclusion that coal
dust does not affect water quality in [he swamp adjacent to the tipple.
In order to clarity this issue, the following stipulation is necessary:
T1lE APPLICANT Sf10ULD RE-ANALYZE AND RE~UBhfIT TffE E.YISTING D,1 T,1 IN TJIB LE 10
TO CONSIDER T11E EFFECTS OF COAL DUST ON WATER /~D,ILITY IN T!/E ADJACENT
S(JAJfP, OR ALTERNATIVELY TIfE APPLICANT SHOULD REDESIGN THE WATER MONITORING
PROGIL1Jd AT Tf1E TIPPLE TO COLLECT USABLE DATA. THIS ZJJFORMATION SHOULD
BE SUBMITTED TO THE DIVISION NO LATER THAN APRIL 1, 1981.

The Sudduth coal seam, underbutden and overburden units of the open Pit .^10. 3 are
in hydrologic communication with the alluvium of Sudduth Draw. The bottom of
open Pit lJO. 7 will be 120 feet below the level of Sudduth Draw. The pit will be
dewatered during mining. These factors will produce an increase in groun~l wa tet
gradient and ground water flow from Sudduth Draw towards the pit. The result will
be depletion of flow in Suddutfl Draw. This depletion can be minimized by decreas-
ing the infiltration over the subcrop in Sudduth Draw. Two stock ponds, one upstream
and one over the subcrop, exist on Sudduth Draw. These ponds increase the amount
and the length of time [hat surface waters can infiltrate tl~e alluvium, as is evident
From the subirriga[ed area below the ponds. h7ater, which is allowed to infiltrate
through the ponds upstream and over the subcrop area, will be lost to beneficial
use in [he immediate area .ind downstream during and after Wining the northern
section of Pit Jlo. 3. Water losses to the pit could be minimized by removing the
twn ponds upstream and nv~~r the subcrop area. To resolve this roncern, [he folla+-
iny stipulation is necr_s:.1r!1:

Water nuality information has been requested by the Division from the sprint at
the old Sudduth :4ine. These analyses will provide actual water quality from an
