THE PURPOSE OF THE PROJECT IS TO CONSTRUCT 150 TURBINE WIND FARM WITH
ASSOCIATED GRAVEL ROADS, ABOVE AND BELOW GROUND ELECTRICAL COLLECTIONS
SYSTEMS, SUBSTATIONS, AND OPERATIONS AND MAINTENANCE FACILITY. APPROXIMATELY
1.800 ACRES WILL BE AFFECTED DURING THIS CONSTRUCTION PERIOD. THE OVERALL
PROJECT AREA ENCOMPASSES APPROXIMATELY 30,000 ACRES LOCATED IN PASQUOTANK AND
PERQUIMANS COUNTIES, LOCATED NORTH OF HERTFORD AND WEST OF ELIZABETH CITY, NC.
SITF DESCRIPTION
THE SITE'S TOPOGRAPHY IS LEVEL COASTAL PLAIN WITH SMALL TO LARGE DRAINAGE
CHANNELS THROUGHOUT THE PROJECT AREA. THERE IS NO EVIDENCE OF SIGNIFICANT
EROSION UNDER PRESENT SITE CONDITIONS. SEDIMENT CONTROL MEASURES WILL BE
IMPLEMENTED TO PREVENT DAMAGE TO THE LOCAL DRAINAGE CHANNELS.
LAND USE WITHIN THE PROJECT AREAS AND IN THE VICINITY IS RURAL AGRICULTURE AND
FORESTED AREAS WITH MINOR RESIDENTIAL AND COMMERCIAL AREAS. THE AGRICULTURAL
LANDS INCLUDE DIVERSE PLANTINGS WITH THE MAJORITY BEING CORN AND WHEAT. THE
FORESTED PROPERTIES ARE ACTIVELY TIMBERED. THERE ARE EXISTING GRAVEL AND SAND
SURFACED PUBLIC AND PRIVATE ROADS THROUGHOUT THE PROJECT AREA.
THE SOIL IN THE PROJECT AREA IS SANDY LOAM WITH SEASONAL HIGH GROUNDWATER
WITHIN 3 FEET OF SURFACE
GFNFRAI NOTFS FOR CONTRACTOR

CLEARING; GRUBBING; STRIPPING TOPSOIL; ROADWAY AND GENERAL GRADING; CONTROLLED
FILL; UTILITY INSTALLATION; PREPARATION OF SUBGRADE; FINE GRADING; CONCRETE
FOUNDATIONS, TOWER INSTALLATIONS; PAVING AND PERMANENT SEEDING.
ALL DISTURBED AREAS SHALL BE LEFT IN A STABILIZED CONDITION UPON COMPLETION OF
THIS CONTRACT.
THE CONTRACTOR IS EXPECTED TO EXAMINE THE SITE TO FAMILIARIZE HIMSELF WITH SITE
CONDITIONS. THE CONTRACTOR SHALL CAREFULLY READ ALL THE SPECIFICATIONS AND
EXAMINE THE DRAWINGS AND DETAILS IN ORDER TO THOROUGHLY FAMILIARIZE HIMSELF
WITH THE WORK TO BE DONE. ANY WORK SHOWN ON THE DRAWINGS OR INCLUDED IN THE
SPECIFICATIONS, OR REASONABLY IMPLIED BY EITHER, SHALL BE PERFORMED THE SAME AS
IF CALLED FOR BY BOTH.
GENERAL: PROVIDE THE WORK FOR EROSION AND SEDIMENT CONTROL AS INDICATED AND
SPECIFIED AS FOLLOWS:
SEDIMENT BASINS; DIVERSION SWALES; CONSTRUCTION ENTRANCE; DRAINAGE STRUCTURES;
OUTLET PROTECTION; EXCAVATION DEWATERING, TEMPORARY AND PERMANENT SEEDING; AND
SILT FENCE.
CONTRACTOR'S RESPONSIBILITY: THE CONTRACTOR SHALL FURNISH THE OWNER A SYSTEM
OF TEMPORARY CONTROLS TO MINIMIZE SOIL SEDIMENT EROSION DURING THE
CONSTRUCTION PERIOD CAUSED BY STORM WATER RUNOFF. WORK SHALL BE PERFORMED AS
CALLED FOR ON THE DRAWINGS AND AS SITE CONDITIONS WARRANT.
EROSION AND SEDIMENT CONTROL: THE CONTRACTOR SHALL PROVIDE EROSION AND
SEDIMENT CONTROL DURING THE PERIOD OF CONSTRUCTION OF THIS PROJECT IN
ACCORDANCE WITH THE APPROVED EROSION AND SEDIMENT CONTROL PLANS AND THE NC
DIVISION 0F WATER QUALITYCONSTRUCTION GENERAL PERMIT
RMIT NCGO1. THE CONTRACTO
R
SHALL PROTECT AND MAINTAIN THE TEMPORARY EROSION AND SEDIMENT CONTROL
STRUCTURES. MAINTENANCE OF THESE FACILITIES SHALL INCLUDE, BUT NOT BE LIMITED
TO, REMOVING SEDIMENT BUILD-UP, REGRADING AND FILLING OF WASHED OUT AREAS,
ADDING EROSION CONTROL BLANKETS, ADDING SILT FENCES AND RIPRAP, AND RESEEDING
AND MULCHING OF THE SWALES DURING THE CONSTRUCTION PERIOD IF DEEMED NECESSARY
BY THE OWNER, OWNER'S ENGINEER, OR THE LAND QUALITY SECTION OF N.C.D.E.N.R.
ACCESS ROAD CONSTRUCTION ON EXISTING PUBLIC AND PRIVATE ROADS: EXISTING ROAD
IMPROVEMENTS WILL INCLUDE REMOVING SOFT SPOTS AS NEEDED, ADDING SOIL STABILIZER
AND/OR AGGREGATE AS RECOMMENDED BY THE GEOTECHNICAL ENGINEER. SILT FENCE
SHALL BE PLACED BETWEEN ROADS AND WATER COURSES WHERE RUNOFF IS DIRECTED
TOWARD A CHANNEL. RUNOFF WILL BE ALLOWED TO DIRECTLY DISCHARGE INTO FARMED
FIELDS.
ACCESS ROAD CONSTRUCTION ON EXISTING FIELDS: NEW ROADS WILL FOLLOW ALONG THE
BANKS OF EXISTING FIELD DRAINAGE CHANNELS. THEIR CONSTRUCTION WILL INCLUDE
ADDING SOIL STABILIZER AND/OR AGGREGATE AS RECOMMENDED BY THE GEOTECHNICAL
ENGINEER. SILT FENCE TO BE PLACED AT THE TOP OF BANK FOR THE LENGTH OF THE
NEW ROAD TO PROVIDE PROTECTION TO ADJACENT WATER COURSE.
PERMANENT AND TEMPORARY CULVERT INSTALLATIONS AND REMOVALS: DRAINAGE CHANNELS
TO BE TEMPORARILY BLOCKED ON EACH SIDE OF THE CULVERT LOCATIONS AND
DEWATERED. AFTER CULVERT AND FILL IS INSTALLED OR REMOVED, TEMPORARY DAMS
WILL BE REMOVED. TEMPORARY ROCK CHECK DAMS SHALL BE PLACED IMMEDIATELY
DOWNSTREAM OF THE DISTURBANCE.
TURBINE SITES: CONSTRUCTION WILL CONSIST OF SILT FENCE INSTALLATION, FOUNDATION
EXCAVATION AND CONSTRUCTION, TEMPORARY SEEDING AND MULCHING OF SOIL STOCKPILES,
FOUNDATION BACKFILLING, AND WORK PLATFORM AND CRANE PAD CONSTRUCTION. AFTER
TURBINE ERECTION, THE WORK PLATFORM AND CRANE PAD WILL BE REMOVED AND
DISTURBED AREAS STABILIZED PER THE VEGETATION PLAN.
CRANE WALK LOCATIONS: ERECTION CRANES WILL TRAVEL BETWEEN TURBINE LOCATIONS
FOLLOWING THE DESIGNATED PATHS SHOWN ON THE PLANS. THESE PATHS WILL RECEIVE
MINOR GRADING AT CULVERT AND ROAD CROSSINGS, SOIL STABILIZATION, OR COMPACTION
AS NEEDED TO PROVIDE A STABLE ACCESS ROUTE WITH A MAXIMUM 1% CROSS SLOPE. IN
MOST CASES, EXISTING VEGETATION WILL NOT BE REMOVED FROM WITHIN OR ALONG THE
CRANE WALK LOCATIONS. EROSION CONTROL MEASURES TO BE PROVIDED AT WATERCOURSE
CROSSINGS, AS SHOWN IN THE DETAILS, WITH DISTURBED AREAS RECEIVING MULCH AND
SEED IN ACCORDANCE WITH THE VEGETATION PLAN.
UNDERGROUND ELECTRICAL COLLECTION SYSTEM: INSTALLATION WILL CONSIST OF PLACING
ELECTRICAL LINES USING STANDARD TRENCHING OR TRENCHLESS METHODS. EXCAVATED
SOILS WILL NOT BE LEFT IN STOCKPILES FOR MORE THAN 24 HOURS. BACKFILLED
TRENCHES SHALL BE SEEDED AND MULCHED ACCORDING TO SPECIFICATIONS IN THE
VEGETATION PLAN.
THE TURBINE, INTERCONNECT, SUBSTATION, OPERATION AND MAINTENANCE FACILITY,
LAYDOWN SITES, AND ANY OTHER TEMPORARY AND PERMANENT IMPROVEMENTS THAT

SURROUNDING THEM WITH SILT FENCE.
8. INSTALL STORM DRAINAGE.
9. FINE GRADE AND STABILIZE ROADS AND SITES TO SUBGRADE ELEVATION PER
GEOTECHNICAL ENGINEER RECOMMENDATIONS.
10. PLACE AGGREGATE BASE ACCORDING TO PLANS AND SPECIFICATIONS.
11. THE CONTRACTOR SHALL BE RESPONSIBLE FOR MAINTAINING ALL SEDIMENT AND
EROSION CONTROL MEASURES THROUGHOUT THE DURATION OF THE CONSTRUCTION PROJECT
ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE INSPECTED WEEKLY AND AFTER
RAINFALL EVENTS. NEEDED REPAIRS WILL BE MADE IMMEDIATELY.
12. INSTALL ALL UNDERGROUND UTILITIES.
13. CONTRACTOR SHALL CLEAN ALL STORM DRAINAGE STRUCTURES, FLUMES, PIPES,
CULVERTS, ETC. PRIOR TO FINAL PAYMENT.
14. AT THE END OF THE PROJECT CONSTRUCTION AND AFTER THE PERMANENT GROUND

CONTROL STRUCTURES AND SEED AND MULCH ALL REMAINING DISTURBED AREAS.
15. ESTIMATED TIME OF CONSTRUCTION FROM INITIAL DISTURBANCE TO FINAL
STABILIZATION--36 MONTHS.
ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CHECKED FOR STABILITY AND
OPERATION FOLLOWING EVERY 0.5" RAINFALL EVENT WITHIN 24 HOURS BUT IN NO CASE
LESS THAN ONCE EVERY WEEK. ANY NEEDED REPAIRS WILL BE MADE IMMEDIATELY TO
MAINTAIN ALL PRACTICES AS DESIGNED.
THE SEDIMENT BASINS WILL BE CLEANED OUT WHEN STORAGE CAPACITY HAS BEEN
APPROXIMATELY 50% FILLED.
SEDIMENT WILL BE REMOVED FROM BEHIND THE SEDIMENT FENCE WHEN IT BECOMES ABOUT
0.5 FT DEEP AT THE FENCE. THE SEDIMENT FENCE WILL BE REPAIRED AS NECESSARY TO
MAINTAIN A BARRIER.
ALL SEEDED AREAS WILL BE FERTILIZED, RESEEDED AS NECESSARY, AND MULCHED
ACCORDING TO SPECIFICATIONS IN THE VEGETATION PLAN.
