GENERAL NOTES :
1 ) PHASE I OF CONVEYOR CONSTRUCTION (WASH PLANT TO TRANSFER POINT) IS
INSIDE THE PRESENT PERMIT BOUNDARY AND IS MOSTLY DISTURBED LAND . A
DRIP PAN WILL BE PROVIDED BELOW THE CONVEYOR TO CATCH MATERIAL DROP-
PING FROM THE CONVEYOR ; SUCH MATERIAL WILL BE CHANNELED T•O THE EXIST-
ING SEDIMENTATION PONDS SOUTH OF COAL CREEK.
- 2) PRIOR TO PHASE 'II OF CONVEYOR CONSTRUCTION (TRANSFER POINT TO END OF
BELT) , CONSTRUCT LOWER SEDIMENTATION POND AS SHOWN ON SHEET 5, CON-
STRUCT CONVEYOR RUNOFF DIVERSION DITCH AS SHOWN ON FIGURES A AND
SECTION B-B' . ROUTE MATERIAL FROM CONVEYOR DRIP PAN ABOVE TRANSFER
POINT INTO CONVEYOR RUNOFF DIVERSION DITCH.
3) PRIOR TO PHASE I PILE CONSTRUCTION, CONSTRUCT UPPER SEDIMENTATION POND
AS SHOWN ON SHEET 5, AND EAST AND WEST RUNOFF COLLECTION DITCHES AS
NEEDED AND STREAM DIVERSION AS SHOWN ON SHEET 4. PHASE I PILE CON-
STRUCTION SHALL CONSIST OF REMOVAL OF VEGETATION AND TOPSOIL, AND C
PILE CONSTRUCTION. �2UNOFF DIVEf2SION 1=0Z PHASE � AND
4) PRIOR TO PHASE II PILE CONSTRUCTION, CONSTRUCT EAST AND WEST P.UNOFF `
COLLECTION DITCHES AS INDICATED ON SHEET 4. REMOVE VEGETATION AND PHASE I I OF C.ONVEY02 CONST UCTIQN
TOPSOIL FROM FOUNDATION AREA AND INITIATE PHASE II CONSTRUCTION.
