SETTLING BASIN CONSTRUCTION SEQUENCE:
1. EXCAVATE AREA FOR THE SETTLING BASIN AS SHOWN PER THE PLAN. DISPOSE OF
EXCAVATED MATERIAL WITHIN THE PIT OR STOCKPILE IN ACCORDANCE TO THE MINING
PLAN AND PERMIT.
2. INSTALL OVERFLOW SPILLWAY IN ACCORDANCE WITH THE DETAILS.
3. SELECT THE PUMP(S) AS RATED FOR TOTAL GPM LESS THAN 2000 GPM OR ADVISE
ENGINEER SO THAT A REVISED DAILY PUMPING TIME CAN BE CALCULATED.
4. INSTALL ANY PUMP HOSES INTO THE BOTTOM OF THE BASIN AND SECURE PROPERLY. ON
THE SUCTION END OF THE PUMP, USE FILTER ATTACHMENT TO PREVENT LARGE EARTH
MATERIALS FROM ENTERING THE BASIN.
5. ONCE SETTLING BASIN IS EXCAVATED PROPERLY AND SLOPES ARE STABILIZED WITH
VEGETATION, THE DE -WATERING CAN COMMENCE.
6. FOLLOW STORMWATER POLLUTION PREVENTION PLAN (SPPP) FOR STANDARD
OPERATIONAL PROCEDURES AND WATER QUALITY TESTING SCHEDULES IN
ACCORDANCE WITH NPDES PERMIT NCG020882.
VEGETATION PLAN SPECIFICATIONS
1. ALL DISTURBED AREAS SHALL BE DRESSED TO THE EXISTING TYPICAL SECTION AND TILLED OR RIPPED
TO A MIN. DEPTH OF 4-INCHES. THE TOP 2 INCHES SHALL BE PULVERIZED TO PROVIDE A UNIFORM
SEEDBED.
2. LIME AND FERTILIZER SHOULD BE INCORPORATED INTO THE SOIL PRIOR TO SEEDING OR SOD. FOLLOW
SOIL TESTS OR AS FOLLOWS:
AGRICULTURAL LIMESTONE - 2 TONS/ACRE
FERTILIZER - 1000 LBS/ACRE (10-10-10)
SUPERPHOSPHATE -500 LBS/ACRE(20%)
MULCH - 2 TONS/ACRE (SMALL GRAIN STRAW)
ANCHOR - ASPHALT EMULSION AT 450 GAL/ACRE
3. FOR OPEN AREAS, USE STRAW MULCH AS A MINIMUM FOR STABILIZATION IF THE AREAS CANNOT BE
SEEDED ACCORDING TO THE PLANTING DATES. OTHER MULCHING PRACTICES ARE LISTED IN SECTION
6.14 OF THE EROSION CONTROL MANUAL FOR MULCHING.
4. FOR DITCHES AND SLOPES, USE EXCELSIOR MATTING AS A MINIMUM FOR STABILIZATION IF THE AREAS
CANNOT BE SEEDED ACCORDING TO THE PLANTING DATES. OTHER MATTING PRACTICES ARE LISTED IN
SECTION 6.14 OF THE EROSION CONTROL MANUAL FOR MULCHING.
5. CHEMICAL STABILIZERS MAY BE USED, BUT IT IS NOT RECOMMENDED FOR VEGETATION GROWTH.
REFER TO THE EROSION CONTROL MANUAL FOR A LIST OF STABILIZERS AND FOLLOW

EROSION CONTROL MAINTENANCE
1. ALL EROSION AND SEDIMENT CONTROL MEASURES WILL BE CHECKED FOR STABILITY AND OPERATION FOLLOWING EVERY
RUNOFF -PRODUCING RAINFALL, BUT IN NO CASE, LESS THAN ONCE EVERY WEEK AND WITHIN 24 HOURS OF EVERY HALF
INCH RAINFALL.
2. ALL POINTS OF EGRESS WILL HAVE CONSTRUCTION ENTRANCES/EXITS THAT WILL BE PERIODICALLY TOP -DRESSED WITH
2-3" COARSE STONE TO MAINTAIN 6" THICKNESS. ENTRANCES/EXITS WILL BE MAINTAINED IN A CONDITION TO PREVENT
MUD OR SEDIMENT FROM LEAVING THE SITE. IMMEDIATELY REMOVE OBJECTIONABLE MATERIAL SPILLED, WASHED, OR
TRACKED ONTO THE CONSTRUCTION ENTRANCE/EXIT OR PUBLIC ROADWAYS. (NCDENR PRACTICE 6.06)
3. SEDIMENT WILL BE REMOVED FROM SEDIMENT BASIN/TAILING POND AS NECESSARY TO MAINTAIN STORAGE VOLUME AS
DESIGNED FOR THE 25-YR DESIGN STORM.
4. SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES HALF-FILLED. THE SEDIMENT FENCE
WILL BE REPAIRED AS NECESSARY TO MAINTAIN A BARRIER. STAKES MUST BE STEEL. STAKE SPACING WILL BE 6 FEET MAX.
WITH THE USE OF EXTRA STRENGTH FABRIC, WITHOUT WIRE BACKING. STAKE SPACING WILL BE 8 FEET MAX. WHEN
STANDARD STRENGTH FABRIC AND WIRE BACKING ARE USED, IF ROCK FILTERS ARE DESIGNED AT LOW POINTS IN THE
SEDIMENT FENCE THE ROCK WILL BE REPAIRED OR REPLACED IF IT BECOMES HALF FULL OF SEDIMENT, NO LONGER
DRAINS AS DESIGNED OR IS DAMAGED. (NCDENR PRACTICE 6.62)
5. INSPECT EARTHEN BERMS AND MAKE ANY REPAIRS AS NECESSARY. REPAIR AND FILL EROSION RILLS OR DEFORMATION.
ENSURE SEDIMENT RUNOFF DOES NOT LEAVE MINING ACTIVITIES AREA PER MINE MAPS. RE -VEGETATE AS NECESSARY
ACCORDING TO SEEDING AND MULCHING SPECIFICATIONS.
6. ALL SEEDED AREAS SHALL BE FERTILIZED, RESEEDED AS NECESSARY AND MULCHED ACCORDING TO SPECIFICATIONS ON
THE SEEDING SCHEDULE TO MAINTAIN A VIGOROUS, DENSE VEGETATIVE COVER.
