SEDIMENT AND EROSION CONTROL NOTES A COM

SEDIMENT AND EROSION CONTROL NOTES CONTINUED:
9. PERMANENTLY STABILIZE ALL DISTURBED AREAS BY SEEDING AND MULCHING PER THE CONTRACT
SPECIFICATIONS, MINIMUM.
10. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND OF GRASS IS
MAINTAINED. AREAS SHOULD BE FERTILIZED AND RESEEDED AS NEEDED. UPON FINAL ACCEPTANCE OF
COMPLETE STABILIZATION OF THE SITE BY THE ENGINEER AND NCDENR, REMAINING TEMPORARY EROSION
AND SEDIMENT CONTROL MEASURES MAY BE REMOVED. ALL TEMPORARY EROSION AND SEDIMENT CONTROL
MEASURES TO BE REMOVED WITHIN 30 DAYS AFTER FINAL SITE STABILIZATION OR AFTER MEASURES ARE NO
LONGER NEEDED, UNLESS OTHERWISE AUTHORIZED BY THE LOCAL PROGRAM ADMINISTRATOR.
11. UPON COMPLETION OF PROJECT, THE SELF-INSPECTION/SELF-MONITORING FORMS SHALL BE SUBMITTED TO
THE ENGINEER FOR CONVEYANCE TO THE OWNER FOR REGULATORY RECORD MAINTENANCE TIME PERIOD.
12. WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT WITH PAVED PUBLIC ROADS, PROVISIONS SHALL
BE MADE TO MINIMIZE THE TRANSPORT OF SEDIMENT ONTO THE PAVED SURFACE. WHERE SEDIMENT IS
TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE ROAD SHALL BE CLEANED THOROUGHLY AT THE END
OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING, AND
TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA (STREET WASHING SHALL BE ALLOWED ONLY AFTER
SEDIMENT IS REMOVED IN THIS MANNER).
13. SITES UTILIZED BY THE CONTRACTOR FOR THE PURPOSE OF STORING EQUIPMENT, EXCESS EXCAVATED
MATERIALS, STRIPPED TOPSOIL, ETC, SHALL BE ENVIRONMENTALLY SUITABLE FOR SUCH PURPOSES AND
SHALL BE APPROVED IN ADVANCE BY THE OWNER. ENVIRONMENTALLY SUITABLE SITES SHALL BE LEVEL,
DEVOID OF MATURE STANDS OF TREES, AND ISOLATED FROM DRAINAGE FACILITIES AND FEATURES, WETLANDS
STREAMS, AND STREAM CORRIDORS. SITES SHALL COMPLY WITH ALL EROSION AND SEDIMENT CONTROL
REQUIREMENTS OF THE TOWN OF CARY.
14. THE CLEANUP AND DISPOSAL OF EXCESS EXCAVATED MATERIALS SHALL BE DONE AS SOON AS PRACTICAL
AND AS THE OWNER MAY DIRECT.
15. CHECK DAMS, SILT FENCE, OR OTHER FILTERING DEVICES SHALL BE MAINTAINED AT AREAS OF STOCKPILED
MATERIALS, EXCAVATED AREAS, CATCH BASINS, AND OTHER STORM WATER INLET STRUCTURES IN
CONSTRUCTION AREAS TO CONTROL SILT RUNOFF.
16. ALL DEWATERING FLOWS SHALL BE KEPT FREE OF SILT, SEDIMENT, DEBRIS, AND OTHER POLLUTANTS
THROUGH APPROPRIATE MEANS (SETTLING BASINS, FILTER, ETC.). FOLLOWING THIS, THE FLOWS SHALL ONLY
BE RELEASED DIRECTLY INTO STORM SEWERS, STREAM CHANNELS, TO OTHER STABILIZED DRAINAGE
COURSES AND NOT INTO EXPOSED SOILS, STEEP SLOPES, OR ANY OTHER SITE WHERE FLOWS COULD
CAUSE FURTHER DAMAGE.
17. CUT AND FILL SLOPES ARE TO BE VERTICALLY TRACKED, HORIZONTALLY SCARIFIED, MATTED, OR OTHERWISE
CONSTRUCTED TO ENHANCE VEGETATIVE GROWTH AND EXPEDITE STABILIZATION. SEEDING SHALL BE
INSTALLED AS PORTIONS OF THESE SLOPES ARE COMPLETED.
18. THE EXISTING EROSION CONTROL FEATURES SUCH AS ROCK CHECK DAMS AND RIP RAP ALONG THE NEW
RECLAIMED WATERLINE ROUTE MUST BE REMOVED AND REPLACED TO FACILITATE INSTALLATION OF THE NEW
RECLAIMED WATERLINE AS SHOWN.
19. IF AT ANY TIME BEFORE THE EXPIRATION OF THE CONTRACT BOND ANY PART OF THE SEEDED AREA IS NOT
IN GOOD CONDITION, THE CONTRACTOR SHALL FERTILIZE AND RESEED AS OFTEN AS NECESSARY TO GET A
GOOD STAND OF GRASS.
20. CONTRACTOR SHALL NOT CROSS ANY DITCH WHEN FLOWING WATER IS PRESENT OR DURING WET WEATHER
UNLESS A PUMP AROUND SYSTEM IS PROVIDED DURING INSTALLATION OF PIPELINE (SEE DETAIL 1/DT5).
PRIOR TO CROSSING A DITCH, CONTRACTOR SHALL VERIFY THAT A TEMPORARY SEDIMENT TRAP OR CHECK
DAM EXISTS DOWNSTREAM OF CROSSING PRIOR TO INSTALLATION OF PIPELINE. IMMEDIATELY AFTER
BACKFILLING OF PIPELINE, DITCH SHALL BE RESTORED TO ORIGINAL GRADE AND STABILIZED. USE EXCELSIOR
MATTING OR RIP RAP AS NECESSARY TO STABILIZE THE DITCH. INSPECT DITCHES IMMEDIATELY AFTER WET
WEATHER EVENT FOR STABILIZATION.
21. WHENEVER CONSTRUCTION CAUSES LAND DISTURBANCE OF ANY KIND WITHIN THE LIMITS OF A DITCH, THE
CONTRACTOR MUST INSTALL EXCELSIOR MATTING OR RIP RAP AS NECESSARY TO STABILIZE THE DITCH.
22. ALL OPEN CUT CROSSINGS OF DITCHES SHALL BE COMPLETED IN ONE WORK DAY.
23. ALL CHECK DAMS SHOULD APPROPRIATELY FILL THE DITCH THEY ARE PLACED IN, SO THAT DRAINAGE IS
FORCED THROUGH THE STRUCTURE. THE ENGINEER WILL NOTIFY THE CONTRACTOR IN WRITING IF ANY
CHECK DAM IS INSUFFICIENTLY SIZED BASED ON THE ENGINEER'S JUDGEMENT. CONTRACTOR WILL REMEDY
THE PROBLEM WITHIN 3 DAYS.

SEDIMENT AND EROSION CONTROL NOTES CONTINUED:
24. JHOOK HAS BEEN CALLED OUT FOR USE AT SEVERAL LOCATIONS WHERE THERE ARE SILT FENCE OUTLETS.
USE OF THE JHOOK MAY BE WARRANTED AT ADDITIONAL LOCATIONS TO PREVENT LONG, UNINTERRUPTED
CHANNEL FLOWS OF STORMWATER AND TO ENHANCE THE EFFECTIVENESS OF THE SILT FENCE OUTLET. THE
ENGINEER SHOULD BE CONSULTED ON PLACEMENT AND/OR RELOCATION OF ANY ADDITIONAL OR EXISTING
JHOOK FEATURES TO THE SILT FENCE.
25. IF EXCAVATED SOIL IS PLACED ON ANY ROADWAY PAVEMENT DURING CONSTRUCTION, CONTRACTOR SHALL
PROVIDE SAND OR SCREENING FINES ALONG PAVEMENT SURFACE FOR SUFFICIENT REMOVAL OF SEDIMENT.
26. IN THE EVENT THAT SEEDING IS PERFORMED AFTER EXCELSIOR MATTING IS PLACED AS A STABILIZING
FEATURE, IT WILL BE NECESSARY TO REMOVE THE MATTING WHEN APPLYING GRASS SEED AND FERTILIZER.
CONTRACTOR MUST REPLACE THE MATTING AT THE END OF EACH DAY TO STABILIZE THE SOILS.
27. SPOIL OR DEBRIS SHALL NOT BE PLACED WITHIN 50' OF STORM DRAINS OR STREAMS.
28. PROVIDE PORTABLE SELF—CONTAINED CONCRETE TRUCK WASHOUT SYSTEM. ALL CONCRETE TRUCKS WILL
UTILIZE PORTABLE WASHOUT SYSTEM FOR CLEAN OUT. NO CONCRETE TRUCK WASHOUT WILL BE ALLOWED
TO REACH GROUND, AND NO CONCRETE WASHOUT DEBRIS SHALL BE ALLOWED ON GROUND.
29. REMOVE DEMOLITION DEBRIS FROM SITE ON A DAILY BASIS AND DISPOSE IN ACCORDANCE WITH APPLICABLE
REGULATIONS.
30. HYDROSEEDING SHALL NOT BE ALLOWED ON THIS PROJECT. CRIMPING STRAW MULCH SHALL NOT BE
ALLOWED ON THIS PROJECT.
31. SEED SHALL BE UNIFORMLY BROADCAST AND LIGHTLY CULTIVATED PRIOR TO MULCH AND TACKIFER
OPERATIONS.
32. MULCH AND TACKIFIER OPERATIONS SHALL BE COMPLETED WITHIN 24 HOURS OF SEEDING.
33. CONTRACTOR STAGING, TEMPORARY STORAGE, LAY DOWN AREAS, AND DIRT PILES SHALL BE WITHIN LIMITS
OF DISTURBANCE.
34. OBTAIN AND PAY FOR EROSION CONTROL PERMITS FOR OFF—SITE STORAGE YARD, BORROW AREA, AND
DISPOSAL AREAS AS REQUIRED. INSTALL AND MAINTAIN EROSION CONTROL DEVICES IN ACCORDANCE WITH
CONTRACTOR'S APPROVED PLAN.
35. A LAYER OF SAND, FINES, OR SCREENINGS SHALL BE PLACED ON PAVED SURFACES BEFORE DEPOSITION
OF EXCAVATED MATERIAL. AFTER REMOVAL OF EXCAVATED MATERIAL FROM PAVED SURFACES, A MECHANICAL
SWEEPER SHALL BE USED TO REMOVE ALL MATERIAL FROM PAVED SURFACES. PAVED SURFACES SHALL BE
SWEPT ON A DAILY BASIS WITH MATERIAL PLACED ON NON—PAVED SURFACES WITHIN LIMITS OF
DISTURBANCE.
36. ON SLOPES GREATER THAN 5:1, DITCHES, AND OTHER AREAS SHOWN ON DRAWINGS, PLACE EROSION
CONTROL BLANKET IMMEDIATELY AFTER BACKFILL AND GRADING, IN ACCORDANCE WITH SPECIFICATIONS.
37. NOTIFICATION OF LAND RESOURCES SEDIMENT AND EROSION CONTROL SELF—INSPECTION PROGRAM:
THE SEDIMENTATION POLLUTION CONTROL ACT WAS AMENDED IN 2006 TO REQUIRE THAT PERSONS
RESPONSIBLE FOR LAND—DISTURBING ACTIVITIES INSPECT A PROJECT AFTER EACH PHASE OF THE PROJECT
TO MAKE SURE THAT THE APPROVED EROSION AND SEDIMENTATION CONTROL PLAN IS BEING FOLLOWED.
RULES DETAILING THE DOCUMENTATION OF THESE INSPECTIONS TOOK EFFECT OCTOBER 1, 2010. THE
INSPECTIONS MUST BE CONDUCTED AFTER EACH PHASE OF THE PROJECT, AND CONTINUED UNTIL
PERMANENT GROUND COVER IS ESTABLISHED IN ACCORDANCE WITH NCGS 113A-54.1 AND 15A NCAC
4B.0131. TO SIMPLIFY DOCUMENTATION OF SELF—INSPECTION REPORTS AND NPDES SELF—MONITORING
REPORTS, A COMBINED FORM IS NOW AVAILABLE. THE NEW FORM WAS DEVELOPED TO SATISFY
REQUIREMENTS OF THE SEDIMENTATION POLLUTION CONTROL ACT AND THE NPDES STORMWATER PERMIT FOR
CONSTRUCTION ACTIVITIES, NCG010000. BEGINNING AUGUST 1, 2013, THE DIVISION OF ENERGY, MINERAL,
AND LAND RESOURCES IS RESPONSIBLE FOR ADMINISTERING BOTH THE SPCA AND THE NPDES STORMWATER
PERMIT FOR CONSTRUCTION ACTIVITIES, NCG 010000. THE COMBINED FORM SHOULD MAKE IT EASIER TO
COMPLY WITH SELF—INSPECTION REQUIREMENTS. THE COMBINED SELF—MONITORING FORM IS AVAILABLE AS A
PDF AND WORD DOCUMENT FROM THE LAND QUALITY WEB SITE,
HTTP://PORTAL.NCDENR.ORG/WEB/LR/EROSION. IF YOU HAVE QUESTIONS OR CANNOT ACCESS THE FORM,
PLEASE CONTACT THE LAND QUALITY SECTION OF THE RALEIGH DENR OFFICE AT [phone].
