PIT WATER RECYCLE/RECIRULATION OPERATION &
MAINTENANCE PLAN RAFTING AND DESIGN O
PUMPING SEQUENCE: SERVICES, INC.
1. ALL EXCAVATED MATERIAL IS BEING REMOVED IN APPROX. 3-4 ACRE 6728 CARBONTON ROAD
SECTIONS WITHIN THE OVERALL MINE EXCAVATION FOOTPRINT. Sanford, North Carolina 27330
2. ONCE THE WATER TABLE IS ENCOUNTERED, PUMPING OF WATER WITHIN [phone] phone
THE MINE SECTION BEGINS AND IS SEPARATED FROM THE REMAINDER OF THE [e-mail]
EXCAVATED POND AREAS BY COFFER DAMS OR UNMINED SECTIONS TO
ENSURE THEY REMAIN FILLED WITH WATER.
3. NO PIT WATER IS DISCHARGED FROM THE SITE DURING EXCAVATION AND
WASHING OF MATERIAL. ALL WATER IS RECYCLED WITHIN THE MINE SITE.
4. PUMP DOWN ACTIVITIES WILL BE CONDUCTED USING AN EIGHT (8) INCH
PUMP RATED AT 2,700 GALLONS PER MINUTE. PUMPING OF EACH SECTION
TAKES APPROX. 3-4 DAYS TO DROP THE WATER LEVEL 10 FEET TO ALLOW
ADDITIONAL MATERIAL REMOVAL FOR NO MORE THAN 2 WEEKS. ONCE
MATERIAL IS MINED WITHIN THIS SECTION OF THE OVERALL MINE EXCAVATION
FOOTPRINT, THE PUMP IS REMOVED AND THIS SECTION OF THE PIT WILL BE
ALLOWED TO REFILL UNTIL THE NEXT PUMP DOWN CYCLE.
5. CONTAINED WITHIN THIS O&M PLAN WILL CONTINUE BE FOLLOWED AS
LONG AS THEY HAVE BEEN EFFECTIVE IN PROTECTING NEARBY WETLANDS.
SHALL IT BE REVEALED THAT THE WATER TABLE IN CERTAIN AREAS OF THE
MINE EXCAVATION FOOTPRINT, IT IS ANTICIPATED THAT THERE WILL BE LESS
PUMPING (AMOUNT AND TIME) TO ACCESS MATERIAL.
PIT WATER RECIRULATION AND RECHARGE:
1. DRY MINE SECTIONS ARE PUMPED INTO PIT SUMP #1 OR 2 (EXCAVATION
PHASE #1 OR 2). THE SEDIMENT PONDS IN THEIR RESPECTIVE EXCAVATION
AREAS WILL BE EXCAVATED TO WHERE THE SEDIMENT POND WILL SIMPLY
GROW AS THEY MINE, TO WHICH THE SEDIMENT POND #1 WILL BECOME THE
SIZE OF THE EXCAVATION PHASE #1 AREA.
2. PIT SUMP#1 IS USED FOR WASHING MINED MATERIAL AND ON-SITE DUST
SUPPRESSION. THE SUMP WILL BE TO PREVIOUSLY MINED AND IMPOUNDED
AREAS SO THAT IT CAN OVERFLOW INTO THE REMAINDER OF EXCAVATED PIT
AREAS THROUGH PROPOSED TEMPORARY DIVERSIONS. THESE DIVERSIONS
ALONG WITH THE REMAINING EXCAVATED PIT AREAS THAT ARE FULL OF
WATER WILL SERVE AS A RECHARGE/HYDROLOGIC BOUNDARY BETWEEN ANY
DRY MINE SECTION AND THE NEARBY WETLANDS ALONG THE SOUTHERN MINE
EXCAVATION AREA.
3. EACH THREE TO FOUR ACRE DRY PIT SECTION IS ONLY DRY FOR THE Q
PERIOD OF TIME IT TAKES TO EXCAVATE THE MATERIAL (APPROX. ONE TO TWO Z
WEEKS).
4. ONCE EACH DRY PIT SECTION HAS BEEN EXCAVATED (DOWN TO AN
AVERAGE DEPTH 35 FT), THE PUMP WILL BE REMOVED ALONG WITH ANY 0 U)
COFFER DAMS TO ALLOW THE GROUND WATER TO FLOW INTO THAT AREA. UJ
� O J
5. ULTIMATELY, THE SUMP AREAS WILL CONNECT TO MAKE ONE LARGE
LAKE AS SHOWN IN THE RECLAMATION PLAN. NATIVE VEGETATIVE SPECIES W C�
WILL BE PLANTED AND PERMANENTLY ESTABLISHED ON ANY REMAINING
DISTURBED AREAS. — � � m � Q

1. A 50 FT WIDE BUFFER CONSISTING OF 30 FEET OF EXISTING UNDISTURBED Z O
VEGETATION AND AN ADDITIONAL 20 FEET OF EARTHEN BERMS FOR A TOTAL W 0%

4. IF IT BECOMES APPARENT THAT THE PERIODIC PUMPING OF PIT WATER W
FROM PIT TO PIT AND INTO THE RECIRCULATION AND RECHARGE DITCHES AND
PONDS IS ADVERSELY IMPACTING THE WATER TABLE AND VEGETATIVE L
VIABILITY WITHIN THESE NEARBY WETLANDS (BESIDES DROUGHT AND
SEASONAL FLUCTUATIONS), PUMPING ACTIVITIES WILL CEASE AND NO
LONGER BE CONDUCTED IN THAT LOCATION. ANY FURTHER MINING IN THAT
LOCATION WILL BE CONDUCTED BY WET MINING WITH NO PUMPING OF WATER.
