2. STREAM AND WETLAND LOCATIONS BASED ON USGS MAPPING AND NATIONAL WETLAND INVENTORY.
3. SITE TO BE RECLAMATOD TO MEET CUMBERLAND COUNTY SECTION 919 QUARRY AND THE NCDEQ MINE PERMIT
RECLAMATION BOND REQUIREMENTS,
4, AS PART OF THE NCDEQ MINE PERMIT THE OWNER IS REQUIRED TO BOND THE RECLAMATION OF THE TOTAL

5. TOPSOIL STOCKPILE MATERIAL SHALL BE USED TO PROVIDE FERTILE SOIL DURING, RECLAMATION TO AID IN THE
ESTABLISHMENT OF PERMANENT GROUND COVER, UNUSED TOPSOIL MATERIAL IN THE STOCKPILE AREAS SHALL
BE REGRADED PER DETAIL TO PROVIDE STABLE SLOPES. ALL SLOPES SHALL BE PERMANENTLY STABILIZED AND
SEEDED.
6. ANY DEBRIS AND DEBRIS BINS WILL BE REMOVED AND PROPERLY D6SPOSED PRIOR TO RECLAMATING PLANT
AREA. IF THE PLANT AREA IS NOT MINED, THE DEBRIS AND DEBRIS BINS WILL BE REMOVED FROM THE SITE AND

MAINTENANCE PLAN
THE OPERATOR IS RESPONSIBLE FOR MAINTAINING EROSION CONTROL DEVICES THROUGHOUT THE PROJECT DURATION.
ALL EROSION AND SEDIMENT CONTROL DEVICES SHALL BE CHECKED FOR STABILITY AND OPERATION FOLLOWING, EVERY RUNOFF -PRODUCING
RAINFALL BUT IN NO CASE LESS THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS SHALL BE MADE IMMEDIATELY TO MAINTAIN ALL DEVICES AS
DESIGNED.
SKIMMER BASINS:
1. BASINS ARE TO BE CLEANED OF SEDIMENT WHEN ITS STORAGE CAPACITY IS REDUCED BY 50%. PLACE SEDIMENT REMOVED FROM THE
BASIN IN A STOCKPILE AREA AS SHOWN ON THE PLAN OR AN AREA THAT HAS ADEQUATE EROSION CONTROL MEASURES.
2. CHECK BERM STRUCTURE, SPILLWAYS, AND SKIMMER PIPE EVERY WEEK FOR EROSION AND PIPING.
3. MAINTAIN BAFFLES AS DIRECTED BELOW,
4, ANY RIP RAP DISPLACED FROM SPILLWAY MUST BE REPLACED IMMEDIATELY.
5. AFTER ALL AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE BASIN (PHASE 2 OF CONSTRUCTION SEQUENCE) AND ALL UNSTABLE
SEDIMENT, GRADE ACCORDING TO GRADING PLAN OR BLEND IN WITH ADJACENT GRADES - ADDITIONAL COMPACTION EFFORTS MAY BE
REQUIRED IF STRUCTURE IS PROPOSED FOR THAT AREA, STABILIZE AREA.
BAFFLES:
1. MAINTAIN ACCESS TO BAFFLES. SHOULD THE FABRIC COLLAPSE, DECOMPOSE, TEAR, OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY.
2. REMOVE BUILDUP SEDIMENT WHEN IT REACHES ONE-HALF FULL. TAKE CARE NOT TO DISTURB BAFFLES DURING CLEANOUT.
SILT FENCE:
1. SEDIMENT SHALL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES ABOUT 0.5 FT DEEP AT THE FENCE, THE FENCE
SHALL BE REPAIRED AS REQUIRED TO MAINTAIN A SUFFICIENT BARRIER.
2. SHOULD THE FABRIC OF A SEDIMENT FENCE COLLAPSE, DECOMPOSE, TEAR. OR BECOME INEFFECTIVE, REPLACE IT PROMPTLY.
3. AFTER ALL AREAS HAVE BEEN PERMANENTLY STABILIZED, REMOVE ALL FENCING MATERIALS AND UNSTABLE SEDIMENT. GRADE AREA
TO GRADING PLAN OR BLEND WITH ADJACENT GRADES. STABILIZE AREA.
TEMPORARY DIVERSIONS:
1, IMMEDIATELY REMOVE EXCESS SEDIMENT FROM FLOW AREA AND REPAIR DIVERSION RIDGE.
2. CAREFULLY CHECK OUTLETS AND MAKE TIMELY REPAIRS AS NEEDED.
3. AFTER ALL AREAS HAVE BEEN STABILIZED REMOVE THE RIDGE AND THE CHANNEL AND GRADE ACCORDING TO GRADING PLAN OR
BLEND WITH ADJACENT GRADES. STABILIZE AREA.
RIP RAP LINED DITCHESICHANNELSIOUTLETS:
1. PAY CLOSE ATTENTION TO INLET AND OUTLET SECTIONS WHERE CONCENTRATED FLOW ENTERS.
2. INSPECT FOR INDICATIONS OF PIPING, SCOUR HOLES, OR BANK FAILURES. MAKE REPAIRS IMMEDIATELY.
3, MAINTAIN VEGETATION ADJACENT TO THE ROCK LINING IN A HEALTHY, VIGOROUS CONDITION TO PROTECT THE AREA FROM EROSION
AND SCOUR.
GRASS LINED DITCHESICHANNELSISWALES.
1, FDLYRIIINrG PIEF' YrCD,11!143rPEIr ii.R,r r-_=r 'EVERYRA9NrAUL.
2. AFTER GRASS HAS ESTABLISHED, INSPECT PERIODICALLY AND AFTER HEAVY RAINFALL, IMMEDIATELY MAKE REPAIRS.
3. PAY CLOSE ATTENTION TO INLET AND OUTLET SECTIONS WHERE CONCENTRATED FLOW ENTERS.
4. GRASS SHOULD BE MAINTAINED IN A HEALTHY VIGOROUS CONDITION AT ALL TIMES, SINCE IT IS THE PRIMARY EROSION PROTECTION.

TEMPORARY SEEDING
PROVIDE TEMPORARY SEEDING TO ALL DENUDED AREAS THAT WELL NOT BE BROUGHT TO FINAL GRADE WITHIN THE FOLLOWING SCHEDULE:
PERMANENT DITCHES --> IMMEDIATELY (ROCK LINED)
SLOPES 4:1 OR STEEPER --> 7 DAYS
ALL OTHER AREAS — 14 DAYS
IF SOILS BECOME COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF 6-8 INCHES.
SEEDBED PREPARATION:
LIME: APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE SOIL PH IS NOT KNOWN, APPLY AT A RATE OF 1 TO I %2 TONS PER
ACRE ON COARSE -TEXTURED SOILS AND 2-3 TONS PER ACRE OF FINE -TEXTURED SOILS. APPLY LIME UNIFORMLY AND INCORPORATE INTO
THE TOP 4-6 INCHES OF SOIL, SOILS WITH PH HIGHER THAN 6 DO NOT NEED LIME.
FEERTILIZER; FERTILIZE ACCORDING TO SOIL TEST RECOMMENDATIONS. WHERE SOIL TESTS ARE NOT AVAILABLE, APPLY A 10-10-10 GRADE
FERTILIZER AT 700-1,000 LBIACRE. INCORPORATE FERTILIZER INTO THE TOP 4-6 INCHES OF SOIL. IF A HYDRAULIC SEEDER IS USED, DO NOT
MIX SEED AND FERTILIZER MORE THAN 30 MINUTES BEFORE APPLICATION,
SURFACE ROUGHENING: IF AREAS TO BE SEEDED BECOME HARDENED. SEALED, OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY
DISKING, RAKING, HARROWING OR OTHER SUITABLE METHODS. GROOVE OR FURROW SLOPES STEEPER THAN 3:1 ON THE CONTOUR
BEFORE SEEDING.
PLANT SELECTION:
SELECT THE APPROPRIATE SPECIES BASED ON THE PLANTING SEASON.
SEEDING:
APPLY SEED WITH A BROADCAST SEEDER, DRILL, CULTIPACKER SEEDER, OR HYDROSEEDER. USE SEEDING RATES GIVEN IN TABLES.
BROADCAST SEEDING AND HYDROSEEDING IS ACCEPTABLE ON STEEP SLOPES WHERE EQUIPMENT CANNOT BE DRIVEN HAND

PERMANENT SEEDING
SEE SEEDING SCHEDULE FOR SEED TYPE AND RATE.
PROVIDE PERMANENT SEEDING TO ALL DENUDED AREAS THAT WILL NOT BE COVERED BY PAVING, BUILDINGS, OR OTHER LANDSCAPING. AREAS
RECEIVING PERMANENT VEGETATION MUST BE STABILIZED WITHIN THE FOLLOWING TIMEFRAMES AFTER FINAL GRADE IS REACHED, UNLESS
TEMPORARY STABILIZATION IS APPLIED.
PERMANENT DITCHES --> IMMEDIATELY (ROCK LINED)
SLOPES 4:1 OR STEEPER --> 7 DAYS
ALL OTHER AREAS — 14 DAYS
COMPLETE GRADING BEFORE PREPARING SEEDBEDS. IF SOILS BECOME COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF 6-8
INCHES.
SEEDBED REQUIREMENTS:
THE SOIL SHOULD MEET THE FOLLOWING MINIMUM CRITERIA FOR VEGETATION ESTABLISHMENT:
o ENOUGH FINE-GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE AND NUTRIENT SUPPLY (AVAILABLE WATER
CAPACITY OF AT LEAST 0.05 INCHES OF WATER TO 1 INCH OF SOIL
• SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION.
• SUFFICIENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT ZONE. THE DEPTH OF ROCK OR IMPERMEABLE LAYERS SUCH AS
HARDPANS SHOULD BE 12 INCHES OR MORE, EXCEPT ON SLOPES STEEPER THAN 2:1 WHERE THE ADDITION OF SOIL IS NOT FEASIBLE.
• A FAVORABLE PH RANGE FOR PLANT GROWTH, USUALLY 6.0-6.5.
• NO LARGE ROOTS, BRANCHES, STONES, LARGE CLODS OF EARTH, AND TRASH. CLODS AND STONES MAY BE LEFT ON SLOPES
STEEPER THAN 3:1 IF THEY ARE TO BE HYDROSEEDED.
IF THE ABOVE CRITERIA CANNOT BE MET, SPECIAL SOIL CONDITIONERS OR TOPSOIL MAY BE APPUED.
SEEDBED PREPARATION:
LIME: APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE SOIL PH IS NOT KNOWN, FOLLOW RATES ON THE SEEDING SPEC
TABLE.
FERTILIZER: FERTILIZE ACCORDING TO SOIL TEST RECOMMENDATIONS. WHERE SOIL TESTS ARE NOT AVAILABLE, FOLLOW RATES ON THE
SEEDING SPEC TABLE.
SURFACE ROUGHENING: IF AREAS TO BE SEEDED BECOME HARDENED, SEALED, OR CRUSTED, LOOSEN IT JUST PRIOR TO SEEDING BY
DISKING, RAKING, HARROWING OR OTHER SUITABLE METHODS. GROOVE OR FURROW SLOPES STEEPER THAN 3:1 ON THE CONTOUR
BEFORE SEEDING.
PLANT SELECTION:
SELECT THE APPROPRIATE SPECIES BASED ON THE PLANTING SEASON, SOIL. TYPE, SLOPES, AND LAND USES. SEE SEEDING SPEC TABLES
IN PLANS FOR RECOMMENDED PERMANENT SEEDING MIXTURE.

MULCH AREAS IMMEDIATELY AFTER SEEDING IN ACCORDANCE WITH RATES GIVEN IN TABLES, ANCHOR MULCH WITH NETTING OR LIQUID
ASPHALT AT A RATE OF 0.10 GALLON PER SQUARE YARD (10 GAL / 1 D00 SQ FT).
HYDROSEEDING:
SURFACE ROUGHENING IS REQUIRED, FINE SEEDBED PREPARATION IS NOT NECESSARY.
RATE OF WOOD FIBER APPLICATION SHOULD BE AT LEAST 4,000-6,000 LBIACRE.

Self -inspections are required during normal business hours in accordance with the table
below. When adverse weather or site conditions would cause the safety of the inspection
personnel to be in jeopardy, the inspection may be delayed until the next business day on
which it is safe to perform the inspection. In addition, when a storm event of equal to or
greater than 1.0 inch occurs outside of normal business hours, the self -inspection shall be
performed upon the commencement of the next business day. Any time when inspections
were delayed shall be noted in the Inspection Record.
