IF POSSIBLE ALL EROSION AND SEDIMENT CONTROL MEASURESARE TO BE PLACED PRIOR TO CLEARING AND/OR LAND DISTURBANCE.4. A COPY OF THE APPROVED EROSION AND SEDIMENT CONTROLPLAN AND PERMIT SHALL BE MAINTAINED ON THE SITE AT ALL TIMES.5. PRIOR TO COMMENCING LAND DISTURBING ACTIVITIES IN AREASOTHER THAN INDICATED ON THESE PLANS (INCLUDING, BUT NOTLIMITED TO OFF-SITE BORROW OR WASTE AREAS, STAGING ORSTORAGE AREAS), THE CONTRACTOR SHALL PREPARE AND SUBMITA SUPPLEMENTARY EROSION CONTROL PLAN TO THE OWNER FORREVIEW AND TO NCDENR REGIONAL OFFICE FOR APPROVAL.CONTRACTOR SHALL PAY ALL FEES REQUIRED AND SHALL INSTALLNECESSARY MEASURES AT NO SEPARATE PAYMENT.

CUT THE TRENCH TO STABLE SOIL MATERIAL, BUT IN NO CASEMAKE IT LESS THAN 2 FEET DEEP. THE CUT-OFF TRENCH MUST EXTEND INTOBOTH ABUTMENTS TO AT LEAST THE ELEVATION OF THE RISER CREST. MAKETHE MINIMUM BOTTOM WIDTH WIDE ENOUGH TO PERMIT OPERATION OFEXCAVATION AND COMPACTION EQUIPMENT, BUT IN NO CASE LESS THAN 2 FEET.MAKE SIDE SLOPES OF THE TRENCH NO STEEPER THAN 1:1. COMPACTIONREQUIREMENTS ARE THE SAME AS THOSE FOR THE EMBANKMENT. KEEP THETRENCH DRY DURING BACKFILLING AND COMPACTION OPERATIONS.3. EMBANKMENT - TAKE FILL MATERIAL FROM THE APPROVED AREAS SHOWN ONTHE PLANS. IT SHOULD BE CLEAN MINERAL SOIL, FREE OF ROOTS, WOODYVEGETATION, ROCKS, AND OTHER OBJECTIONABLE MATERIAL. SCARIFY AREASON WHICH FILL IS TO BE PLACED BEFORE PLACING FILL. THE FILL MATERIALMUST CONTAIN SUFFICIENT MOISTURE SO IT CAN BE FORMED BY HAND INTO ABALL WITHOUT CRUMBLING. IF WATER CAN BE SQUEEZED OUT OF THE BALL, IT ISTOO WET FOR PROPER COMPACTION. PLACE FILL MATERIAL IN 6 TO 8 INCHCONTINUOUS LAYERS OVER THE ENTIRE LENGTH OF THE FILL AREA ANDCOMPACT IT. COMPACTION MAY BE OBTAINED BY ROUTING THE CONSTRUCTIONHAULING EQUIPMENT OVER THE FILL SO THAT THE ENTIRE SURFACE OF EACHLAYER IS TRAVERSED BY AT LEAST ONE WHEEL OR TREAD TRACK OF HEAVYEQUIPMENT, OR A COMPACTOR MAY BE USED. CONSTRUCT THE EMBANKMENTTO AN ELEVATION 10% HIGHER THAN THE DESIGN HEIGHT TO ALLOW FORSETTLING.4. SECURELY ATTACH THE RISER TO THE BARREL OR BARREL STUB TO MAKE AWATERTIGHT STRUCTURAL CONNECTION. SECURE ALL CONNECTIONS BETWEENBARREL SECTIONS BY APPROVED WATERTIGHT ASSEMBLIES. PLACE THEBARREL AND RISER ON A FIRM, SMOOTH FOUNDATION OF IMPERVIOUS SOIL. DONOT USE PERVIOUS MATERIAL SUCH AS SAND, GRAVEL, OR CRUSHED STONE ASBACKFILL AROUND THE PIPE OR ANTISEEP COLLARS. PLACE THE FILL MATERIALAROUND THE PIPE SPILLWAY IN 4 INCH LAYERS, AND COMPACT IT UNDER ANDAROUND THE PIPE TO AT LEAST THE SAME DENSITY AS THE ADJACENTEMBANKMENT. CARE MUST BE TAKEN NOT TO RAISE THE PIPE FROM FIRMCONTACT WITH ITS FOUNDATION WHEN COMPACTING UNDER THE PIPEHAUNCHES. PLACE A MINIMUM DEPTH OF 2 FEET OF COMPACTED BACKFILLOVER THE PIPE SPILLWAY BEFORE CROSSING IT WITH CONSTRUCTIONEQUIPMENT. ANCHOR THE RISER IN PLACE BY CONCRETE OR OTHERSATISFACTORY MEANS TO PREVENT FLOTATION. IN NO CASE SHOULD THE PIPECONDUIT BE INSTALLED BY CUTTING A TRENCH THROUGH THE DAM AFTER THEEMBANKMENT IS COMPLETE.5. INSTALL THE EMERGENCY SPILLWAY IN UNDISTURBED SOIL. THEACHIEVEMENT OF PLANNED ELEVATIONS, GRADE, DESIGN WIDTH, ANDENTRANCE AND EXIT CHANNEL SLOPES ARE CRITICAL TO THE SUCCESSFULOPERATION OF THE EMERGENCY SPILLWAY.6. DISCHARGE THE WATER INTO THE BASIN IN A MANNER TO PREVENT EROSION.USE DIVERSIONS WITH OUTLET PROTECTION TO DIVERT SEDIMENT-LADENWATER TO THE UPPER END OF THE POOL AREA TO IMPROVE TRAP EFFICIENCY.7.

THE WIRE MESH SHALLBE MADE OF GALVANIZED STEEL WIRE HAVING A MINIMUM DIAMETEROF 3 MM. ALL WIRE USED IN THE FABRICATION OF THE GABION AND INTHE WIRING OPERATIONS SHALL CONFORM TO US FEDERALSPECIFICATION QQ-W-461H AND POSSESS A SOFT TENSILE STRENGTHWITH A CLASS 3 FINISH 5 ZINC COATING IN ACCORDANCE WITH ASTMA-641. PREFORMED STEEL WIRE SPIRAL BINDERS WITH A 3” PITCH AREUSED TO ASSEMBLE AND INTERCONNECT EMPTY GABIONS AND SHALLMEET THE SAME SPECIFICATION AS THE WIRE USED IN THE MESH.AFTER ASSEMBLY, THE INDIVIDUAL GABION UNITS AREINTERCONNECTED USING THE SAME WIRE AND THE CONNECTIONSHOULD BE MADE NO LESS THAN EVERY 6” ALONG THE PERIMETER.THEY SHOULD THEN FILLED WITH CLEAN, HARD STONE FROM 4” - 8”INDIAMETER. THE LIDS ARE THEN CLOSED AND JOINED TO THE TOPEDGES OF THE INDIVIDUAL GABIONS AND DIAPHRAGMS. THE USE OFEXPEDIENT CLIPS OR HOG RINGS FOR THIS PURPOSE IS NOTPERMITTED.IF PROPERLY CONSTRUCTED, THE LIDS AND PANELS SHOULD MEETCLOSELY WITHOUT GAPS AND THAT THE TIES PROVIDE A TIGHT JOINTAT ALL PANELS AND DIAPHRAGMS.NTS
