MULCH SHALL BE FREE FROM NOXIOUS WEEDS, MOLD, AND OTHER

DELETERIOUS MATERIALS. MULCH MATERIALS SHALL BE NATIVE TO

THE REGION. HAY OR STRAW MULCH SHALL BE SPREAD UNIFORMLY

AT THE RATE OF 2 TONS PER ACRE. MULCH SHALL BE SPREAD BY

HAND, BLOWER-TYPE MULCH SPREADER, OR OTHER APPROVED

METHOD. MULCHING SHALL BE STARTED ON THE WINDWARD SIDE

OF RELATIVELY FLAT AREAS OR ON THE UPPER PART OF STEEP

SLOPES, AND CONTINUED UNIFORMLY UNTIL THE AREA IS COVERED.

THE MULCH SHALL NOT BE BUNCHED OR CLUMPED. SUNLIGHT SHALL

NOT BE COMPLETELY EXCLUDED FROM PENETRATING TO THE GROUND

SURFACE. ALL AREAS INSTALLED WITH SEED SHALL BE MULCHED ON

THE SAME DAY AS THE SEEDING. MULCH SHALL BE ANCHORED

IMMEDIATELY FOLLOWING SPREADING.

STALKS FROM OATS, WHEAT, RYE, BARLEY, OR RICE. FURNISH IN

AIR-DRY CONDITION AND OF PROPER CONSISTENCY FOR PLACING

WITH COMMERCIAL MULCH BLOWING EQUIPMENT. STRAW SHALL

CONTAIN NO FERTILE SEED.

HAY SHALL BE NATIVE HAY, SUDAN-GRASS HAY, BROOMSEDGE HAY,

OR OTHER HERBACEOUS MOWING. AIR-DRY CONDITION AND OF

PROPER CONSISTENCY FOR PLACING WITH COMMERCIAL MULCH

BLOWING EQUIPMENT. HAY SHALL BE STERILE, CONTAINING NO

FERTILE SEED.

MECHANICAL ANCHOR SHALL BE A V-TYPE-WHEEL LAND PACKER;

A SCALLOPED-DISK LAND PACKER DESIGNED TO FORCE MULCH INTO

THE SOIL SURFACE; OR OTHER SUITABLE EQUIPMENT.

WOOD CELLULOSE FIBER SHALL BE APPLIED AS PART OF THE

HYDROSEEDING OPERATION. THE MULCH SHALL BE MIXED AND

APPLIED IN ACCORDANCE WITH THE MANUFACTURER'S

RECOMMENDATIONS.

SOIL ON SLOPES UP TO A MAXIMUM 3-HORIZONTAL-TO-1-VERTICAL

SHALL BE TILLED TO A MINIMUM 4 INCH DEPTH. ON SLOPES BETWEEN

3-HORIZONTAL-TO-1-VERTICAL AND 1-HORIZONTAL-TO-1-, THE SOIL

SHALL BE TILLED TO A MINIMUM 2 INCH DEPTH BY SCARIFYING

WITH HEAVY RAKES, SPIKED TOOTH HARROW, CHISEL PLOWS, OR

SIMILAR IMPLEMENTS, OR OTHER SIMILAR METHOD. ROTOTILLERS

SHALL BE USED WHERE SOIL CONDITIONS AND LENGTH OF SLOPE

PERMIT. AREAS COMPACTED BY CONSTRUCTION OPERATIONS SHALL

BE COMPLETELY PULVERIZED BY TILLAGE. THE FERTILIZER MAY BE

APPLIED DURING THIS PROCEDURE.

SOIL EROSION AND SEDIMENT CONTROL MEASURES

1. ALL EROSION AND SEDIMENTATION CONTROL MEASURES NOTED SHALL BE INSTALLED PRIOR TO START OF CONSTRUCTION AND

SHALL REMAIN IN EFFECT AND BE MAINTAINED THROUGHOUT THE PERIOD OF CONSTRUCTION.

2. SEDIMENTATION FROM WORK ON THIS SITE SHALL BE CONTAINED ON THE SITE AND SHALL NOT BE ALLOWED TO COLLECT ON ANY

OFFSITE AREA OR IN WATERWAYS.

3. CONTRACTOR SHALL APPLY TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES AS SHOWN ON THESE PLANS OR AS DIRECTED BY

THE CONTRACTING OFFICER OR HIS/HER DESIGNATED REPRESENTATIVE. CONTRACTOR SHALL REMOVE TEMPORARY MEASURES AS SOON

AS PERMANENT STABILIZATION OF SLOPES, DITCHES, AND OTHER EARTH CHANGES HAVE BEEN ACCOMPLISHED.

4. DAILY INSPECTION SHALL BE MADE BY THE CONTRACTOR TO DETERMINE THE EFFECTIVENESS OF EROSION CONTROL MEASURES, AND

ANY NECESSARY REPAIRS SHALL BE MADE WITHOUT DELAY.

5. PERMANENT SOIL EROSION CONTROL MEASURES FOR ANY DISTURBED LAND AREA SHALL BE STABLIZIED AS SOON AS POSSIBLE. WHEN IT

IS NOT POSSIBLE TO PERMANENTLY STABILIZE A DISTURBED AREA IMMEDIATELY AFTER COMPLETION OF GRADING WORK, TEMPORARY

SOIL EROSION CONTROL MEASURES SHALL BE IMPLEMENTED IMMEDIATELY. ALL TEMPORARY SOIL EROSION CONTROL MEASURES SHALL

BE MAINTAINED UNTIL PERMANENT SOIL EROSION CONTROL MEASURES ARE IMPLEMENTED.

6. CONTRACTOR SHALL PROVIDE PERMANENT GROUND COVER FOR ALL DISTURBED AREAS WITH 3H:1V SLOPES OR FLATTER WITHIN 14 CALENDAR

DAYS FOLLOWING THE COMPLETION OF CONSTRUCTION AND ALL DISTURBED AREAS WITH SLOPES STEEPER THAN 3H:1V WITHIN 7 CALENDAR DAYS

AFTER COMPLETION OF CONSTRUCTION.

7. SEE SECTION 32 92 19 IN THE SPECIFICATIONS FOR DETAILS REGARDING MAINTENANCE AND APPLICATION OF SEEDING, SOIL CONDITIONERS, FERTILIZERS, AND MULCH.

TEMPORARY SILT FENCE NOTES:

1. THE EXISTING TEMPORARY SILT FENCE (TSF) LOCATED WITHIN THE FOOTPRINT OF THE PROPOSED

CELL 1 EXTERIOR TOE BERMS SHALL BE REMOVED AND DISPOSED OF OFF GOVERNMENT

PROPERTY. NEW TEMPORARY SILT FENCE SHALL BE INSTALLED AT LOCATIONS SHOWN ON THE

PLANS. THE CONTRACTOR SHALL COMPLETE ALL TEMPORARY SILT FENCE INSTALLATION PRIOR TO

COMMENCEMENT OF CLEARING AND EARTHWORK OPERATIONS.

2. WIRE FABRIC SHALL BE A MINIMUM OF 32" IN WIDTH AND SHALL HAVE A MINIMUM OF 6 LINE WIRES

WITH 12" STAY SPACING.

3. FILTER FABRIC SHALL HAVE A MINIMUM OF 36" WIDTH. FILTER FABRIC SHALL BE FASTENED

ADEQUATELY TO THE FENCE FABRIC AS DIRECTED BY THE CONTRACTING OFFICER.

4. STEEL POSTS SHALL BE 5 FEET (MIN) IN HEIGHT AND SHALL BE OF THE SELF-FASTENER ANGLE

STEEL TYPE.

5. THE CONTRACTOR SHALL INSPECT TEMPORARY SILT FENCE AT LEAST ONCE EVERY 7 DAYS AND

AFTER ANY SIGNIFICANT STORM THAT PRODUCES 0.5 INCHES OR MORE RAINFALL AT THE SITE

AND MAKE ANY REQUIRED REPAIRS IMMEDIATELY. REMOVE SEDIMENT DEPOSITS AS NECESSARY

TO PROVIDE ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE PRESSURE ON

THE FENCE. TAKE CARE TO AVOID UNDERMINING THE FENCE DURING CLEANOUT.

6. THE CONTRACTOR SHALL PERFORM ALL WORK IN SUCH A MANNER THAT STATE WATER QUALITY

STANDARDS OUTSIDE OF THE CONSTRUCTION AREA ARE NOT VIOLATED. ALL EROSION AND

SEDIMENT CONTROL MEASURES SHALL BE IN ACCORDANCE WITH THE NORTH CAROLINA EROSION

AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL.
