MANUAL.

2. THE CONTRACTOR IS RESPONSIBLE FOR PERFORMING ENVIRONMENTAL

DUE DILIGENCE AND DETERMINING THAT ALL IMPORTED FILL MEETS THE

EPA & STATE DEQ DEFINITION OF CLEAN FILL. CLEAN FILL MEANS THAT THE

FILL MATERIAL IS NOT CONTAMINATED BY SOLID WASTES, INFECTIOUS

ASSESSMENTS OR AUDITS. ANALYTICAL TESTING IS NOT A REQUIRED PART

OF DUE DILIGENCE UNLESS VISUAL INSPECTION AND/OR REVIEW OF THE

PAST LAND USE OF THE PROPERTY INDICATES THAT THE FILL MAY HAVE

BEEN SUBJECTED TO A SPILL OR RELEASE OF REGULATED SUBSTANCE. IF

THE FILL MAY HAVE BEEN AFFECTED BY A SPILL OR RELEASE OF A

REGULATED SUBSTANCE, IT MUST BE TESTED TO DETERMINE IF IT

QUALIFIES AS CLEAN FILL.

4. SILT FENCE IS SHOWN IN THE APPROXIMATE LOCATION OF PLACEMENT.

ADDITIONAL SILT FENCE SHALL BE PLACED TO PROTECT ANY ADDITIONAL

AREAS DISTURBED DURING CONSTRUCTION.

5. SILT FENCE SHALL BE INSTALLED PRIOR TO LAND DISTURBANCE. SILT

FENCE SHALL BE MAINTAINED DURING CONSTRUCTION AND ONLY

REMOVED WHEN A UNIFORM 80% VEGETATIVE COVER HAS BEEN

ESTABLISHED AND APPROVED BY OWNER.

6. ALL WASTE MATERIAL SHALL BE PROPERLY RECYCLED OR DISPOSED OF

PER LOCAL OR STATE REQUIREMENTS.

7. CONTRACTOR SHALL PLACE 6" TOPSOIL AND SEED ON ALL CUT AND FILL

SLOPES AS SPECIFIED UNLESS ANOTHER SURFACE MATERIAL IS

STABILIZED WITH EROSION CONTROL BLANKETS IMMEDIATELY UPON

COMPLETION OF GRADING ACTIVITIES.

9. TOP SOIL STOCKPILE, CONCRETE WASHOUT AND WASTE DISPOSAL AREAS

MAY BE PLACED IN A CENTRAL LOCATION WITHIN THE LIMITS OF

DISTURBANCE TO ACCOMMODATE CONSTRUCTION AND MATERIAL

LAYDOWN REQUIREMENTS.

10. PERIMETER SEDIMENT CONTROL MEASURES (SILT FENCE) SHALL BE

IMPLEMENTED AS THE FIRST STEP OF GRADING AND WITHIN SEVEN (7)

DAYS FROM THE START OF GRUBBING AND SHALL CONTINUE TO FUNCTION

UNTIL UPSLOPE AREAS DRAINING TO THEM ARE PERMANENTLY

11. STREETS DIRECTLY ADJACENT TO CONSTRUCTION ENTRANCES AND

RECEIVING TRAFFIC FROM THE DEVELOPMENT AREA, SHALL BE CLEANED

DAILY TO REMOVE SEDIMENT TRACKED OFF-SITE. IF APPLICABLE, THE

CATCH BASINS ON THESE STREETS NEAREST TO THE CONSTRUCTION

ENTRANCES SHALL ALSO BE CLEANED WEEKLY.

12. ALL EROSION AND SEDIMENT CONTROL PRACTICES SPECIFIED ON THIS

PLAN SHALL CONFORM WITH DETAILS AND SPECIFICATIONS OUTLINED IN

THE CURRENT VERSION OF THE NORTH CAROLINA EROSION & SEDIMENT

CONTROL PLANNING & DESIGN MANUAL OR OTHER STANDARDS

ACCEPTABLE TO NORTH CAROLINA DEQ.

13. EROSION AND SEDIMENT CONTROL PRACTICES NOT ALREADY SPECIFIED

ON THIS PLAN MAY BE NECESSARY DUE TO UNFORESEEN ENVIRONMENTAL

CONDITIONS AND/OR CHANGES IN DRAINAGE PATTERNS CAUSED BY

EARTH-MOVING ACTIVITY.

14. SOIL STOCKPILES, TOPSOIL OR OTHERWISE, SHALL BE SITUATED AWAY

FROM STREETS, SWALES, OR OTHER WATERWAYS AND SHALL BE SEEDED

AND/OR MULCHED IN ACCORDANCE WITH THE NORTH CAROLINA DEQ

TIMEFRAME FOR STABILIZATION.

15. ON-SITE PERSONNEL SHALL TAKE ALL NECESSARY MEASURES TO COMPLY

WITH APPLICABLE REGULATIONS REGARDING FUGITIVE DUST EMISSIONS.

16. CONCRETE WASH WATER SHALL NOT BE ALLOWED TO FLOW TO STREAMS,

DITCHES, STORM DRAINS, OR ANY OTHER WATER CONVEYANCE. A SUMP

OR PIT WITH NO POTENTIAL FOR DISCHARGE SHALL BE CONSTRUCTED IF

NEEDED TO CONTAIN CONCRETE WASH WATER. FIELD TILE OR OTHER

SUBSURFACE DRAINAGE STRUCTURES WITHIN 10 FT. OF THE SUMP SHALL

BE CUT AND PLUGGED. FOR SMALL PROJECTS, TRUCK CHUTES MAY BE

RINSED AWAY FROM ANY WATER CONVEYANCES.
