TOPSOILING & STOCKPILING (3.30) - TOPSOIL WILL BE STRIPPED FROM AREAS TO BE GRADED AND STOCKPILED FOR LATER USE. STOCKPILES ARE TO BE STABILIZED WITH TEMPORARY VEGETATION OR TO HAVE SILT FENCE INSTALLED ALONG THE LOWER PERIMETER TO PROTECT DOWNSTREAM AREAS. 9. TEMPORARY SEEDING (3.31) - AREAS NOT BROUGHT. TO FINAL GRADE FOR A PERIOD OF MORE THAN 14 DAYS SHALL BE STABILIZED WITH A TEMPORARY SEED MIXTURE ACCEPTABLE FOR THAT TIME OF YEAR. CRIMPING, PUNCH ROLLER -TYPE ROLLERS, OR TRACK WALKING MAY BE USED TO INCORPORATE STRAW MULCH INTO THE SOIL ON SLOPES IF STRAW IS TO BE USED. 10. PERMANENT SEEDING (3.32) - AREAS BROUGHT TO FINAL GRADE OR THOSE CONSTRUCTION AREAS THAT WILL REMAIN DORMANT FOR YEAR OR MORE SHALL BE STABILIZED WITH A PERMANENT SEED MIXTURE ACCEPTABLE TO THAT TIME OF YEAR. PREPARE SURFACE WITH APPROVED TREATMENT AND ADDITIVES PRIOR TO APPLYING SEED 11. DUST CONTROL (3.39) - DUST CONTROL METHODS MUST BE USED TO REDUCE THE AMOUNT OF AIRBORNE DUST DURING ALL PHASES OF CONSTRUCTION WHERE SOIL IS EXPOSED OR DISTURBED. MANAGEMENT STRATEGIES 12. THE CONSTRUCTION ENTRANCE AND PERIMETER EROSION CONTROL MEASURES SUCH AS TREE PROTECTION AND SILT FENCE SHALL BE INSTALLED AS THE FIRST STEP OF DISTURBANCE. 13. TEMPORARY SEEDING OR OTHER STABILIZATION METHODS, SUCH AS BASE AGGREGATE WILL FOLLOW IMMEDIATELY AFTER REACHING FINAL GRADES. 14.

THE JOB SUPERINTENDENT SHALL BE RESPONSIBLE FOR THE INSTALLATION AND MAINTENANCE OF ALL EROSION AND SEDIMENT CONTROL PRACTICES. 16. AFTER BEING NOTIFIED BY THE EROSION AND SEDIMENT CONTROL ADMINISTRATOR, THE TEMPORARY EROSION AND SEDIMENT CONTROLS CAN BE CLEANED UP OR REMOVED, AND THE SEDIMENT TRAPS CAN BE FILLED IN AND SEEDED, THEREBY REDIRECTING DRAINAGE TO THE PERMANENT FACILITIES. PERMANENT STABILIZATION SEEDING SHALL BE DONE WITH KENTUCKY 31 TALL FESCUE IN ACCORDANCE TO STANDARD AND SPECIFICATION 3.32, PERMANENT SEEDING, OF THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK. ANY FERTILIZER AND LIME APPLICATIONS SHALL BE IN ACCORDANCE WITH SOIL TEST RESULTS. ALL SEEDED AREAS WILL BE STRAW MULCHED TO PROTECT AGAINST RILL EROSION AND TO PRESERVE SOIL MOISTURE THAT WILL ENHANCE SEED GERMINATION. CRIMPING, PUNCH ROLLER -TYPE ROLLERS, OR TRACK WALKING MAY BE USED TO INCORPORATE STRAW MULCH INTO THE SOIL ON SLOPES IF STRAW IS TO BE USED. EROSION CONTROL MAINTENANCE 1. IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CHECKED DAILY AND AFTER EACH SIGNIFICANT RAINFALL. THE FOLLOWING ITEMS WILL BE CHECKED IN PARTICULAR: 2. THE CONSTRUCTION ENTRANCE SHALL BE CHECKED DAILY FOR SOIL BUILDUP.

SILT FENCE SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST DAILY DURING PROLONGED RAINFALL. CLOSE ATTENTION SHALL BE PAID TO THE REPAIR OF DAMAGED SILT FENCE RESULTING FROM END RUNS AND UNDERCUTTING. SHOULD THE FABRIC ON A SILT FENCE DECOMPOSE OR BECOME INEFFECTIVE PRIOR TO THE END OF THE EXPECTED USABLE LIFE AND THE BARRIER STILL BE NECESSARY, THE FABRIC SHALL BE REPLACED PROMPTLY. SEDIMENT DEPOSITS SHOULD BE REMOVED AFTER EACH STORM EVENT. THEY MUST BE REMOVED WHEN DEPOSITS REACH APPROXIMATELY ONE-HALF THE HEIGHT OF THE BARRIER. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT FENCE IS NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM WITH THE EXISTING GRADE, PREPARED, AND SEEDED. 4. STORMWATER CONVEYANCE CHANNELS (WHERE APPLICABLE): 4.1. GRASS LINED CHANNELS - DURING THE INITIAL ESTABLISHMENT, GRASS LINED CHANNELS SHOULD BE REPAIRED IMMEDIATELY AND RE-ESTABLISHED IF NECESSARY. AFTER GRASS HAS BECOME ESTABLISHED, THE CHANNEL SHOULD BE CHECKED PERIODICALLY TO DETERMINE IF THE GRASS IS WITHSTANDING FLOW VELOCITIES WITHOUT DAMAGE. IF THE CHANNEL IS TO BE MOWED, IT SHOULD BE DONE IN A MANNER THAT IT WILL NOT DAMAGE THE GRASS. 5. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND IS MAINTAINED. AREAS SHOULD BE FERTILIZED AND RE -SEEDED AS NEEDED. IN THE EVENT THAT THE APPLIED SEEDING FAILS TO TAKE HOLD, BLANKET MATTING SHALL BE PLACED IN APPROPRIATE AREAS DEEMED NECESSARY BY THE ENGINEER OR EROSION CONTROL INSPECTOR.
