WEST VIRGINIA EROSION AND SEDIMENT
CONTROL FIELD MANUAL, MAY 2012
DETAIL 6 -SEDIMENT AND EROSION CONTROL
FOR ACCESS ROADS AND DRIVEWAYS
NOT TO SCALE
NOT TO SCALE
INTRODUCTION
1. PROTECTIVE FENCING SHOULD BE INSTALLED TO PREVENT ACCESS TO POTENTIALLY
HAZARDOUS AREAS OF A CONSTRUCTION SITE.
CONDITIONS WHERE PRACTICE APPLIES
1. APPLICABLE TO ANY CONTROL MEASURE OR SERIES OF MEASURES, WHICH CAN BE CONSIDERED
UNSAFE BY VIRTUE OF POTENTIAL FOR ACCESS BY THE PUBLIC. THE DESIGNER, DEVELOPER,
AND CONTRACTOR SHOULD ALWAYS BE SURE THAT THE MOST APPROPRIATE TYPE OF FENCE
IS UTILIZED FOR A PARTICULAR NEED.
CONSTRUCTION SPECIFICATIONS
1. SAFETY FENCES SHOULD BE LOCATED SO AS TO CREATE A FORMIDABLE BARRIER TO
UNDESIRED ACCESS, WHILE ALLOWING FOR THE CONTINUATION OF NECESSARY CONSTRUCTION
OPERATIONS.
2. SAFETY FENCES ARE MOST APPLICABLE TO THE CONSTRUCTION OF TRAPS AND DAMS. IN USE
WITH THOSE STRUCTURES, SAFETY FENCES SHOULD BE LOCATED FAR ENOUGH BEYOND THE
OUTER TOE OF THE EMBANKMENT TO ALLOW FOR THE PASSAGE OF MAINTENANCE VEHICLES.
FENCES SHOULD NOT BE INSTALLED ACROSS THE SLOPE OF A DAM OR DIKE.
3. SIGNS NOTING POTENTIAL HAZARDS SUCH AS 'DANGER" OR "HAZARDOUS AREA - KEEP OUT"
SHOULD BE POSTED AND EASILY SEEN BY ANYONE APPROACHING THE PROTECTED AREA.
4. PLASTIC (POLYETHYLENE) FENCE MAY BE USED AS SAFETY FENCING, PRIMARILY IN SITUATIONS
WHERE THE NEED IS FOR A TEMPORARY BARRIER. THE FENCE SHOULD MEET THE PHYSICAL
REQUIREMENTS NOTED IN TABLE 3.04.1.
5. SAFETY FENCES SHOULD BE INSTALLED PRIOR TO THE SEDIMENT CONTROL MEASURE BECOMING
ACCESSIBLE.
6. APPLICABLE WARNING SIGNS NOTING HAZARDOUS CONDITIONS MUST BE INSTALLED IMMEDIATELY
UPON INSTALLATION OF SAFETY FENCE.
7. CHAIN LINK FENCE SHOULD BE USED FOR PERMANENT STRUCTURES (GREATER THAN ONE
YEAR).
MAINTENANCE
1. SAFETY FENCE SHALL BE CHECKED REGULARLY FOR WEATHER-RELATED OR OTHER DAMAGE.
ANY NECESSARY REPAIRS MUST BE MADE IMMEDIATELY.
2. CARE SHOULD BE TAKEN TO SECURE ALL ACCESS POINTS (GATES) AT THE END OF EACH
WORKING DAY. ALL LOCKING DEVICES MUST BE REPAIRED OR REPLACED AS NECESSARY.

MAINTENANCE NOTES:
1. INSPECT RIPRAP OUTLET STRUCTURES WEEKLY AND
AFTER SIGNIFICANT (1/2 INCH OR GREATER)
RAINFALL EVENTS TO SEE IF ANY EROSION AROUND
OR BELOW THE RIPRAP HAS TAKEN PLACE, OR IF
STONES HAVE BEEN DISLODGED. IMMEDIATELY MAKE
ALL NEEDED REPAIRS TO PREVENT FURTHER
DAMAGE.
CONSTRUCTION SPECIFICATIONS:
1. ENSURE THAT THE SUBGRADE FOR THE FILTER
AND RIPRAP FOLLOWS THE REQUIRED LINES AND
GRADES SHOWN IN THE PLAN. COMPACT ANY
FILL REQUIRED IN THE SUBGRADE TO THE
DENSITY OF THE SURROUNDING UNDISTURBED
MATERIAL. LOW AREAS IN THE SUBGRADE ON
UNDISTURBED SOIL MAY ALSO BE FILLED BY
INCREASING THE RIPRAP THICKNESS.
2. THE RIPRAP AND GRAVEL FILTER MUST CONFORM
TO THE SPECIFIED GRADING LIMITS SHOWN ON
THE PLANS.
3. FILTER CLOTH, WHEN USED, MUST MEET DESIGN
REQUIREMENTS AND BE PROPERLY PROTECTED
FROM PUNCHING OR TEARING DURING
INSTALLATION. REPAIR ANY DAMAGE BY
REMOVING THE RIPRAP AND PLACING ANOTHER
PIECE OF FILTER CLOTH OVER THE DAMAGED
AREA. ALL CONNECTING JOINTS SHOULD OVERLAP
SO THE TOP LAYER IS ABOVE THE DOWNSTREAM
LAYER A MINIMUM OF 1 FOOT. IF THE DAMAGE IS
EXTENSIVE, REPLACE THE ENTIRE FILTER CLOTH.
4. RIPRAP MAY BE PLACED BY EQUIPMENT, BUT
TAKE CARE TO AVOID DAMAGING THE FILTER.
5. THE MINIMUM THICKNESS OF THE RIPRAP SHOULD
BE 1.5 TIMES THE MAXIMUM STONE DIAMETER.
6. RIPRAP MAY BE FIELD STONE OR ROUGH QUARRY
STONE. IT SHOULD BE HARD, ANGULAR, HIGHLY
WEATHER -RESISTANT AND WELL GRADED.
7. CONSTRUCT THE APRON ON ZERO GRADE WITH
NO OVERFILL AT THE END. MAKE THE TOP OF
THE RIPRAP AT THE DOWNSTREAM END LEVEL
WITH THE RECEIVING AREA OR SLIGHTLY BELOW
IT.
8. ENSURE THAT THE APRON IS PROPERLY ALIGNED
WITH THE RECEIVING STREAM AND PREFERABLY
STRAIGHT THROUGHOUT ITS LENGTH. IF A CURVE
IS NEEDED TO FIT SITE CONDITIONS, PLACE IT IN
THE UPPER SECTION OF THE APRON.
9. IMMEDIATELY AFTER CONSTRUCTION,STABILIZE ALL
DISTURBED AREASWITH VEGETATION (PRACTICES
6.10, TEMPORARY SEEDING, AND 6.11,
PERMANENT SEEDING).

CONSTRUCTION SPECIFICATIONS:
1. KEEP CLEARING AND EXCAVATION OF THE STREAM BANKS AND BED AND
APPROACH SECTIONS TO A MINIMUM
2. DIVERT ALL SURFACE WATER FROM THE CONSTRUCTION STIE ONTO UNDISTURBED
AREAS ADJOINING THE STREAM
3. KEEP STREAM CROSSINGS AT RIGHT ANGLES TO THE STREAM FLOW
4. ALIGN ROAD APPROACHES WITH THE CENTER LINE OF THE CROSSING FOR A
MINIMUM DISTANCE OF 30 FEET. RAISE BRIDGE ABUTMENTS AND CULVERT FILLS A
MINIMUM OF 1 FOOT ABOVE THE ADJOINING APPROACH SECTIONS TO PREVENT
EROSION FROM SURFACE RUNOFF AND TO ALLOW ALL FLOOD FLOWS TO PASS
AROUND THE STRUCTURE.
5. STABILIZE ALL DISTURBED AREAS SUBJECT TO FLOWING WATER, INCLUDING
PLANNED OVERFLOW AREAS, WITH RIPRAP OR OTHER SUITABLE MEANS IF DESIGN
VELOCITY EXCEEDS THE ALLOWABLE FOR THE IN-PLACE SOIL.
6. ENSURE THAT BYPASS CHANNELS NECESSARY TO DEWATER THE CROSSING SITE
ARE STABLE BEFORE DIVERTING THE STREAM. UPON COMPLETION OF THE
CROSSING, FILL, COMPACT, AND STABILIZE THE BYPASS CHANNEL APPROPRIATELY
7. REMOVE TEMPORARY STREAM CROSSINGS IMMEDIATELY WHEN THEY ARE NO
LONGER NEEDED. RESTORE THE STREAM CHANNEL TO ITS ORIGINAL
CROSS-SECTION, AND SMOOTH AND APPROPRIATELY STABILIZE ALL DISTURBED
AREAS.
8. ANY IN -STREAM SEDIMENT CONTROL MEASURES MUST BE REMOVED UPON
STABILIZATION OF THE AREA.
MAINTENANCE NOTES:
1. INSPECT TEMPORARY STREAM CROSSINGS AFTER RUNOFF PRODUCING RAINS TO
CHECK FOR BLOCKAGE IN CHANNED, EROSION OF ABUTMENTS, CHANNEL
SCOUR, RIPRAP DISPLACEMENT, OR PIPING. MAKE ALL REPAIRS IMMEDIATELY TO
PREVENT FURTHER DAMAGE TO INSTALLATION.
DETAIL 3 -CULVERT
STREAM CROSSING
NOT TO SCALE
NOTES:
1. USE DAM AND PUMP METHOD ON NARROW WATERCOURSES WITH LIMITED STREAM FLOW TO PREVENT SEDIMENTATION AND INTERRUPTION OF STREAM
FLOW DURING CROSSING CONSTRUCTION. IF FISH PASSAGE IS A CONCERN, THIS METHOD IS NOT APPROPRIATE.
2. SCHEDULE CONSTRUCTION DURING PERIOD OF LOW STREAM FLOW.
3. SET UP PUMP AND HOSE AS SHOWN, OR USE OTHER PRACTICAL ALTERNATIVES. PUMP SHOULD HAVE TWICE THE PUMPING CAPACITY OF
ANTICIPATED FLOW. HAVE STANDBY PUMP ON SITE.
4. INSTALL UPSTREAM DAM COMPOSED OF SANDBAGS OR CLEAN GRAVEL WITH PLASTIC UNDERLINING. INSTALL DOWNSTREAM DAM IF REQUIRED TO KEEP
STREAMBED DRY.
5. EXCAVATE TRENCH AND INSTALL PIPE BY LOWERING IN UNDER HOSE. MOVE HOSE AS REQUIRED OR DISCONNECT IF TEMPORARY FLOW BLOCKAGE IS
ACCEPTABLE. BACKFILL TRENCH.
6. DISMANTLE DOWNSTREAM DAM, THEN UPSTREAM DAM. KEEP PUMP RUNNING TO MAINTAIN FLOW.
7. MONITOR DAM AND PUMP FOR PROPER OPERATION THROUGHOUT THE CROSSING INSTALLATION.
8. IN HIGH QUALITY (HQ) OR EXCEPTIONAL VALUE (EV) STREAMS, USE 12" FILTER SOCK IN PLACE OF SILT FENCE.
9. ENSURE DISTURBED AREAS ARE SEEDED AND MULCHED USING SEED MIXTURES AS SPECIFIED IN THE INCLUDED TABLE.
STREAM CROSSING RESTORATION:
1. ONCE THE SOIL EROSION AND SEDIMENT CONTROL MEASURES AND THE REQUIRED WATER FLOW CONTROL MEASURES ARE IN PLACE, CONTRACTOR CAN
PROCEED WITH TRENCH EXCAVATION.
2. ALL EXCAVATED MATERIALS THAT WILL BE USED AS BACKFILL SHALL BE PLACED IN A TEMPORARY STOCKPILE LOCATED OUTSIDE THE CHANNEL.
CHANNEL BED MATERIAL SHALL BE SEGREGATED FOR LATER USE. A SEDIMENT BARRIER SHALL BE INSTALLED BETWEEN THE STOCKPILE AND STREAM
CHANNEL.
3. COMPLETE TRENCH EXCAVATION FOR PIPELINE CONSTRUCTION, PLACE PIPELINE AND BACKFILL.
4. STREAM BANKS SHALL BE RESTORED TO PRE -CONSTRUCTION CONFIGURATIONS, AS MUCH AS POSSIBLE, AND STABILIZED.
5. RE -SEED RESTORED STREAM BANKS AT THE RATE OF 15 LBS./ACRE WITH 'RIPARIAN BUFFER MIX' BY ERNST CONSERVATION SEEDS (MIX
ERNMIX-178) OR APPROVED EQUAL.
6. RESTORED STREAM BANKS AND ADJACENT DISTURBED AREAS TO BE STABILIZED WITH APPROVED EROSION CONTROL BLANKET USING MANUFACTURER
RECOMMENDED STAPLES AND PATTERNS.
7. PLACE SALVAGED BED MATERIAL ON THE CHANNEL BED IN THE DISTURBED AREA.

MAINTENANCE
1. THE DEVELOPER/OWNER SHALL BE RESPONSIBLE FOR MAINTENANCE OF THE FILTER CURTAIN
FOR THE DURATION OF THE PROJECT IN ORDER TO ENSURE THE CONTINUOUS PROTECTION OF
THE WATERCOURSE.
2. SHOULD REPAIRS TO THE GEOTEXTILE FABRIC BECOME NECESSARY, THERE ARE NORMALLY
REPAIR KITS AVAILABLE FROM THE MANUFACTURERS; MANUFACTURER'S INSTRUCTIONS MUST
BE FOLLOWED TO ENSURE THE ADEQUACY OF THE REPAIR.
3. WHEN THE CURTAIN IS NO LONGER REQUIRED AS DETERMINED BY THE INSPECTOR, THE
CURTAIN AND RELATED COMPONENTS SHALL BE REMOVED IN SUCH A MANNER TO MINIMIZE
TURBIDITY. REMAINING SEDIMENT SHALL BE SUFFICIENTLY SETTLED BEFORE REMOVING THE
CURTIAN. SEDIMENT MAY BE REMOVED AND THE ORIGINAL DEPTH (OR PLAN ELEVATION)
RESTORED. AND SPOILS MUST BE TAKEN TO UPLAND AREA AND BE STABILIZED.
CONSTRUCTION SPECIFICATIONS
1. PLACE STONE TO THE LINES AND DIMENSIONS SHOWN IN THE PLAN ON A FILTER FABRIC
FOUNDATION
2. KEEP THE CENTER STONE SECTION AT LEAST 9 INCHES BELOW NATURAL GROUND LEVEL WHERE
THE DAM ABUTS THE CHANNEL BANKS.
3. EXTEND STONE AT LEAST 1.5 FEET BEYOND THE DITCH BANK TO KEEP WATER FROM CUTTING
AROUND THE ENDS OF THE CHECK DAM.
4. SET SPACING BETWEEN THE DAMS TO ASSURE THAT THE ELEVATION AT THE TOP OF THE LOWER
DAM IS THE SAME AS THE TOE ELEVATION OF THE UPPER DAM.
5. PROTECT THE CHANNEL AFTER THE LOWEST CHECK DAM FROM HEAVY FLOW THAT COULD
CAUSE EROSION.
6. MAKE SURE THAT THE CHANNEL REACH ABOVE THE MOST UPSTREAM DAM IS STABLE.
7. ENSURE THAT OTHER AREAS OF THE CHANNEL, SUCH AS CULVERT ENTRANCES BELOW THE
CHECK DAMS, ARE NOT SUBJECT TO DAMAGE OR BLOCKAGE FROM THE DISPLACED STONES.
MAINTENANCE
1. INSPECT CHECK DAMS AND CHANNELS AT LEAST WEEKLY AND AFTER EACH SIGNIFICANT (0.5
INCH OR GREATER) RAINFALL EVENT AND REPAIR IMMEDIATELY. CLEAN OUT SEDIMENT, STRAW,
LIMBS, OR OTHER DEBRIS THAT COULD CLOG THE CHANNEL WHEN NEEDED.
2. ANTICIPATE SUBMERGENCE AND DEPOSITION ABOVE THE CHECK DAM AND EROSION FROM
HIGH FLOWS AROUND THE EDGES OF THE DAM. CORRECT ALL DAMAGE IMMDIATELY. IF
SIGNIFICANT EROSION OCCURS BETWEEN DAMS, ADDITIONAL MEASURES CAN BE TAKEN, SUCH
AS INSTALLING A PROTECTIVE RIPRAP LINER IN THAT PORTION OF THE CHANNEL.
3. REMOVE SEDIMENT ACCUMULATED BEHIND THE DAMS AS NEEDED TO PREVENT DAMAGE TO
CHANNEL VEGETATION, ALLOW THE CHANNEL TO DRAIN THROUGH THE STONE CHECK DAM,
AND PREVENT LARGE FLOWS FROM CARRYING SEDIMENT OVER THE DAM. ADD STONE TO DAMS
AS NEEDED TO MAINTAIN DESIGN HEIGHT AND CROSS SECTION.

RIPARIAN PERMANENT S]E]ESSS COASTAL REGION
Only Lometa in eastern coastal plain (Plant Hardiness Zone 8).
Pick at least four species. including one from each type.
RIPARIAN SEEDBED PREPARATION
1. Disturbed soils within riparian areas must be amended to provide an optimum environment for seed
germination and seedling growth. The surface soil must be loose enough for water infiltration and root
penetration. The pH of the soil must be such that it is not toxic and nutrients are available. Riparian areas are
generally considered rich in nutrients due to flooding and deposition, however, these areas can be highly
variable (i.e., narrow steep corridors in the mountains, artificial fill material on top of alluvial floodplains in the
Piedmont). Soil analysis should be performed to determine nutrient and lime needs of each site. Appropriate
levels of phosphorus and potassium are critical for permanent seed establishment. Appropriate pH levels are
between 5.5 and 7. Riparian buffers regulated for nutrient management may be limited to a single application
of fertilizer. Construction activities within the riparian area can greatly compact soils. Suitable mechanical
means such as disking, raking, or harrowing must be employed to loosen the compacted soil prior to
seeding.
MAINTENANCE
1. MANY OF THE RECOMMENDED PERMANENT GRASS SPECIES MAY REQUIRE TWO YEARS FOR
ESTABLISHMENT, DEPENDING ON THE SITE CONDITIONS. INSPECT SEEDED AREAS FOR FAILURE
AND MAKE NECESSARY REPAIRS, SOIL AMENDMENTS, AND RESEEDINGS. IF WEEDY EXOTIC
SPECIES HAVE OVERTAKEN THE AREA AFTER THE FIRST GROWING SEASON, THE INVADING
SPECIES MUST BE ERADICATED TO ALLOW NATIVE SPECIES TO GROW. NATIVE VEGETATIONS
ARE DIFFICULT TO MANAGE AND TAKE LONGER TO ESTABLISH. MONITOR THE SITE UNTIL LONG
TERM STABILITY HAS BEEN ESTABLISHED.

GENERAL PIPELINE CONSTRUCTION
PIPELINE CONSTRUCTION WORKSPACE REQUIREMENTS ARE A FUNCTION OF PIPE DIAMETER, EQUIPMENT SIZE, TOPOGRAPHY, GEOLOGICAL ROCK FORMATIONS,
LOCATION OF CONSTRUCTION SUCH AS AT ROAD CROSSINGS OR RIVER CROSSINGS, PIPELINE CROSSOVERS, METHODS OF CONSTRUCTION SUCH AS BORING OR
OPEN -CUT CONSTRUCTION, OR EXISTING SOIL CONDITIONS ENCOUNTERED DURING CONSTRUCTION. AS THE DIAMETER OF THE PIPELINE BEING INSTALLED INCREASES,
SO DOES THE DEPTH OF TRENCH, EXCAVATED SPOIL MATERIAL, EQUIPMENT SIZE, AND ULTIMATELY THE AMOUNT OF CONSTRUCTION WORK SPACE THAT WILL BE
REQUIRED TO CONSTRUCT A PROJECT. ALL WORKSPACE LOCATIONS FOR A GIVEN PROJECT WILL BE SHOWN ON THE CONSTRUCTION ALIGNMENT SHEETS.
ADDITIONAL CONSTRUCTION RIGHT-OF-WAY (ROW) MAY BE REQUIRED AT SPECIFIC LOCATIONS INCLUDING, BUT NOT LIMITED TO, STEEP SIDE OR VERTICAL SLOPES,
ROAD CROSSINGS, PIPELINE CROSSOVERS, AREAS REQUIRING SUPPLEMENTAL TOPSOIL SEGREGATION, AND STAGING AREAS ASSOCIATED WITH WETLAND AND
WATERBODY CROSSINGS.
ALL CONSTRUCTION ACTIVITIES, INCLUDING STAGING AREAS AND ADDITIONAL SPOIL STORAGE AREAS, ARE RESTRICTED TO THE CONSTRUCTION ROW LIMITS IDENTIFIED
ON THE CONSTRUCTION ALIGNMENT SHEETS, EXCEPT FOR SPECIFIC ACTIVITIES IN LIMITED, NON -WETLAND, AND NON -RIPARIAN AREAS THAT ARE ALLOWED BY THE FERC
PLAN AND PROCEDURES (I.E., SLOPE BREAKERS, ENERGY -DISSIPATING DEVICES, DEWATERING STRUCTURES, AND DRAIN TILE SYSTEM REPAIRS). USE OF THESE LIMITED
AREAS IS SUBJECT TO LANDOWNER OR LAND MANAGEMENT AGENCY APPROVAL AND COMPLIANCE WITH ALL APPLICABLE SURVEY, PERMIT, AND REPORTING
REQUIREMENTS; THEREFORE, PRIOR DOMINION ENERGY TRANSMISSION INC. (DETI) APPROVAL IS REQUIRED TO USE THESE AREAS. IN SOME CASES, FEDERAL, STATE,
AND LOCAL PERMITS AND AUTHORIZATIONS MAY REQUIRE ADDITIONAL APPROVALS.
CROSS-COUNTRY PIPELINE CONSTRUCTION TYPICALLY PROCEEDS IN ASSEMBLY LINE FASHION, WITH MULTIPLE STAGES OF CONSTRUCTION OCCURRING
SIMULTANEOUSLY AT DIFFERENT LOCATIONS TO MINIMIZE THE TIME NEEDED TO COMPLETE THE PROJECT. THE STAGES OF CONSTRUCTION INCLUDE: SURVEY AND
FLAGGING, CLEARING AND MOWING, GRUBBING AND GRADING, TRENCHING, PIPE ASSEMBLY (INCLUDING STRINGING, BENDING, WELDING, TESTING, COATING, AND
LOWERING -IN), BACKFILLING, HYDROSTATIC TESTING, FINAL GRADING, AND RESTORATION. EROSION AND SEDIMENT CONTROL (ESC) MEASURES TO BE UTILIZED ALONG
THE PIPELINE ALIGNMENT ARE DEPICTED ON THE CONSTRUCTION ALIGNMENT SHEETS.
SITE PREPARATION
1. SURVEY AND FLAG THE CONSTRUCTION ROW AND MARK ENVIRONMENTALLY SENSITIVE AREAS.
2. INSTALL ROCK CONSTRUCTION ENTRANCES.
3. INSTALL SAFETY FENCES PRIOR TO ESC INSTALLATION.
4. CONDUCT INITIAL CLEARING, LIMITED TO THAT NECESSARY TO INSTALL TEMPORARY SEDIMENT BARRIERS.
5. INSTALL PERIMETER ESCS PRIOR TO ANY BULK EARTH -MOVING ACTIVITY (ROAD GRADING, ROAD USE, LOG SKIDDING, ETC.).
6. CONDUCT PROGRESSIVE CLEARING WITH INSTALLATION OF TEMPORARY SEDIMENT BARRIERS AND TEMPORARY EQUIPMENT BRIDGES KEEPING PACE WITH
CLEARING.
7. MODIFY ACCESS ROADS BY GRADING AND INSTALLING STONE WHERE NEEDED.
8. GRADE THE ROW AND SEGREGATE TOPSOIL WHERE NECESSARY.
9. INSTALL TEMPORARY SLOPE BREAKERS, ALSO REFERRED TO AS TEMPORARY ROW DIVERSIONS OR WATER BARS, AS NEEDED TO REDUCE RUNOFF VELOCITY AND
DIVERT WATER OFF THE CONSTRUCTION ROW.
10. CONSTRUCT SOIL DIVERSION BERM ON DOWNSLOPE OF ROW WHERE NOTED ON PLANS. BERM IS NECESSARY IN LOCATIONS WHERE DRAINAGE PATTERN WOULD
CAUSE RUNOFF TO DRAIN ACROSS THE ROW AND WILL SERVE TO DIRECT THE RUNOFF TO THE WATERBAR OUTLETS.
PIPE INSTALLATION
11. EXCAVATE TRENCH TO ACCOMMODATE NEW PIPELINE SEGMENT.
12. STRING PIPE, BEND THE PIPE JOINTS.
13. WELD THE PIPE, INSPECT WELDS.
14. LOWER THE PIPE INTO THE TRENCH.
15. INSTALL PERMANENT TRENCH PLUGS.
16. BACKFILL THE TRENCH.
17. INSTALL HYDROSTATIC TEST DEWATERING STRUCTURES.
18. HYDROSTATICALLY TEST THE PIPE AND DEWATER.
19. BRING THE PIPELINE TO GAS SERVICE.
20. FINAL GRADE ROW AND TEMPORARY WORKSPACES TO ORIGINAL CONTOURS TO THE EXTENT PRACTICABLE.
21. INSTALL PERMANENT INTERCEPTOR DIKES.
22. REPLACE SEGREGATED TOPSOIL.
RESTORATION
23. CONDUCT ROW RESTORATION AND CLEANUP. AS SOON AS SLOPES, CHANNELS, DITCHES, AND OTHER DISTURBED AREAS REACH FINAL GRADE, THEY WILL BE
STABILIZED WITHIN THE TIMEFRAME SPECIFIED.
24. APPLY SOIL AMENDMENTS, PERMANENT SEED, MULCH, AND/OR EROSION CONTROL FABRIC.
25. RESTORE TEMPORARY ACCESS ROADS OR ANY PAVED SURFACES TO ORIGINAL CONDITION.
26. REMOVE TEMPORARY SEDIMENT BARRIERS FROM AN AREA WHEN REPLACED BY PERMANENT EROSION CONTROL MEASURES OR WHEN THE AREA HAS BEEN

WETLAND CROSSING
PROCEDURES USED TO INSTALL A PIPELINE ACROSS WETLANDS VARY DEPENDING ON THE LEVEL OF SOIL STABILITY AND SATURATION ENCOUNTERED DURING
CONSTRUCTION. DETI WILL COMPLY WITH USACE PERMIT TERMS AND CONDITIONS. IT WILL ASSEMBLE THE PIPELINE IN AN UPLAND AREA UNLESS THE
WETLAND IS DRY ENOUGH TO ADEQUATELY SUPPORT SKIDS AND PIPE. DETI WILL USE "PUSH-PULL" OR "FLOAT" TECHNIQUES TO PLACE THE PIPE IN THE TRENCH
WHERE WATER AND OTHER SITE CONDITIONS ALLOW.
THE FOLLOWING BEST MANAGEMENT PRACTICES (BMPS) ARE TO BE EMPLOYED DURING STANDARD WETLAND CROSSINGS:
1. ASSEMBLE THE PIPELINE IN AN UPLAND AREA UNLESS THE WETLAND IS DRY ENOUGH TO ADEQUATELY SUPPORT SKIDS AND PIPE.
2. DO NOT USE ROCK, SOIL IMPORTED FROM OUTSIDE THE WETLAND, TREE STUMPS, OR BRUSH RIPRAP TO STABILIZE THE ROW.
3. PERFORM TOPSOIL SEGREGATION, INCLUDING SEGREGATING THE SURFICIAL 12 INCHES OF TOPSOIL FROM THE AREA DISTURBED BY TRENCHING, EXCEPT IN
AREAS WHERE STANDING WATER IS PRESENT OR SOILS ARE SATURATED. IMMEDIATELY AFTER BACKFILLING IS COMPLETE, RESTORE THE SEGREGATED
TOPSOIL TO ITS ORIGINAL LOCATION.
4. IF REQUIRED, DEWATERING SHOULD BE CONDUCTED AS DESCRIBED BELOW.
5. MINIMIZE THE LENGTH OF TIME THAT TOPSOIL IS SEGREGATED AND THE TRENCH IS OPEN. DO NOT TRENCH THE WETLAND UNTIL THE PIPELINE IS ASSEMBLED
AND READY FOR LOWERING -IN.
6. INSTALL PERMANENT TRENCH BREAKERS AT THE WETLAND BOUNDARIES AND/OR SEAL THE TRENCH BOTTOM AS NECESSARY TO MAINTAIN THE ORIGINAL
WETLAND HYDROLOGY AT LOCATIONS WHERE THE PIPELINE TRENCH MAY DRAIN A WETLAND.
7. INSTALL A PERMANENT SLOPE BREAKER AND A TRENCH BREAKER AT THE BASE OF SLOPES NEAR THE BOUNDARY BETWEEN THE WETLAND AND ADJACENT
UPLAND AREAS FOR EACH WETLAND CROSSED.
8. INSTALL A PERMANENT SLOPE BREAKER ACROSS THE CONSTRUCTION ROW AT THE BASE OF SLOPES GREATER THAN 5 PERCENT WHERE THE BASE OF THE
SLOPE IS LESS THAN 50 FEET FROM THE WETLAND, OR AS NEEDED TO PREVENT SEDIMENT TRANSPORT INTO THE WETLAND. IN SOME AREAS, AN EARTHEN
BERM MAYBE SUITABLE ASA SEDIMENT BARRIER ADJACENT TO THE WETLAND.
9. WHEN REQUIRED, ADDITIONAL FILL MATERIAL IMPORTED FROM OFF THE ROW MUST BE APPROVED BY THE EI.
10. PRE -CONSTRUCTION WETLAND CONTOURS AND FLOW REGIMES WILL BE RESTORED TO THE EXTENT PRACTICAL.
WETLAND CLEANUP AND RESTORATION
11. FOR EACH WETLAND CROSSED, DETI WILL INSTALL A TRENCH BREAKER AT THE BASE OF SLOPES NEAR THE BOUNDARY BETWEEN THE WETLAND AND
ADJACENT UPLAND AREAS. IT WILL INSTALL A PERMANENT SLOPE BREAKER ACROSS THE CONSTRUCTION ROW AT THE BASE OF SLOPES GREATER THAN 5
PERCENT WHERE THE BASE OF THE SLOPE IS LESS THAN 50 FEET FROM THE WETLAND, OR AS NEEDED TO PREVENT SEDIMENT TRANSPORT INTO THE
WETLAND. IN SOME AREAS, AN EARTHEN BERM MAYBE SUITABLE ASA SEDIMENT BARRIER ADJACENT TO THE WETLAND.
12. RESTORE PRE -CONSTRUCTION WETLAND CONTOURS TO MAINTAIN THE WETLAND HYDROLOGY.
13. REVEGETATION AND PERMANENT ROW MAINTENANCE PROCEDURES AS WELL AS THE USE OF LIME, MULCH, OR FERTILIZER IN WETLAND AREAS IS
ADDRESSED IN THE FERC RESTORATION AND REHABILITATION PLAN.
14. DETI WILL NOT USE HERBICIDES OR PESTICIDES IN OR WITHIN 100 FEET OF A WETLAND, EXCEPT AS ALLOWED BY THE APPROPRIATE FEDERAL OR STATE
AGENCY.
15. REMOVE PROJECT -RELATED MATERIAL USED TO SUPPORT EQUIPMENT ON THE CONSTRUCTION ROW, INCLUDING TIMBER MATTING AND PREFABRICATED
EQUIPMENT MATS, UPON COMPLETION OF CONSTRUCTION.
16. REMOVE TEMPORARY SEDIMENT BARRIERS LOCATED ATTHE BOUNDARY BETWEEN WETLAND AND ADJACENT UPLAND AREAS AFTER UPLAND
REVEGETATION AND STABILIZATION OF ADJACENT UPLAND AREAS ARE SUCCESSFUL.
17. WITHIN 3 YEARS AFTER CONSTRUCTION, FILE A REPORT WITH FERC IDENTIFYING THE STATUS OF THE WETLAND REVEGETATION EFFORTS AND
DOCUMENTING SUCCESS.
STREAM CROSSING
18. THE TEMPORARY WATERWAY CROSSING WILL BE AT RIGHT ANGLES TO THE STREAM. WHERE APPROACH CONDITIONS DICTATE, THE CROSSING MAY VARY
15 DEGREES FROM A LINE DRAWN PERPENDICULAR TO THE CENTER LINE OF THE STREAM AT THE INTENDED CROSSING LOCATION.
19. EQUIPMENT BRIDGES MAYBE INSTALLED AND USED WHERE NEEDED TO ALLOW EQUIPMENT ACCESS ACROSS WATERBODIES. EQUIPMENT BRIDGES WILL
BE ABLE TO WITHSTAND THE ANTICIPATED LOADING OF THE CONSTRUCTION TRAFFIC, HAVE ONE TRAFFIC LANE, AND HAVE THE MINIMUM WIDTH OF 12 FEET
WITH A MAXIMUM WIDTH OF 20 FEET.
20. PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED AREAS WITHIN 7 DAYS AFTER FINAL GRADE IS REACHED ON ANY
PORTION OF THE SITE. THE AREAS DISTURBED DURING INSTALLATION WILL BE STABILIZED WITHIN 7 DAYS OF THAT DISTURBANCE IN ACCORDANCE WITH NC
DEQ REQUIREMENTS.
21. INTERMITTENT AND PERENNIAL STREAMS WILL BE CROSSED USING PROPERLY DESIGNED AND CONSTRUCTED STRUCTURES INSTALLED AT RIGHT ANGLES
TO THE ACCESS ROAD.
22. STRUCTURES WILL NOT IMPEDE FISH PASSAGE OR STREAM FLOW.
23. APPROACHES TO STREAM CROSSINGS WILL BE STABILIZED WITH GRAVEL, MULCH OR OTHER SUITABLE MATERIAL FOR A MINIMUM DISTANCE OF 50 FEET
ON EACH SIDE OF THE CROSSING, OR TO THE TOP OF THE GRADE THAT IS CONTRIBUTING SEDIMENT TO THE STREAM CROSSING.
24. UNTIL THE EQUIPMENT BRIDGE IS INSTALLED, ONLY CLEARING EQUIPMENT AND EQUIPMENT NECESSARY FOR INSTALLATION OF EQUIPMENT BRIDGES
MAY CROSS THE WATERBODY, AND THE NUMBER OF CROSSINGS WILL BE LIMITED TO ONE CROSSING PER PIECE OF EQUIPMENT, UNLESS OTHERWISE
AUTHORIZED BY THE APPROPRIATE PERMITTING AGENCY. EI APPROVAL IS REQUIRED PRIOR TO EQUIPMENT CROSSING A WATERBODY WITHOUT AN
EQUIPMENT BRIDGE.
25. CONSTRUCT AND MAINTAIN EQUIPMENT BRIDGES THAT ALLOW UNRESTRICTED FLOW AND PREVENT SEDIMENT FROM ENTERING THE WATERBODY.
26. DO NOT USE SOIL TO CONSTRUCT OR STABILIZE EQUIPMENT BRIDGES.
27. DESIGN AND MAINTAIN EQUIPMENT BRIDGES TO PREVENT SEDIMENT FROM ENTERING THE WATERBODY.
28. REMOVE TEMPORARY EQUIPMENT BRIDGES AS SOON AS PRACTICABLE AFTER SEEDING.
29. IF THERE WILL BE MORE THAN 1 MONTH BETWEEN FINAL CLEANUP AND THE BEGINNING OF PERMANENT SEEDING AND REASONABLE ALTERNATIVE
ACCESS TO THE ROW IS AVAILABLE, REMOVE TEMPORARY EQUIPMENT BRIDGES AS SOON AS PRACTICABLE AFTER FINAL CLEANUP.
SITE INSPECTION FREQUENCY FOR SENSITIVE AREAS
EROSION AND SEDIMENT CONTROL INSPECTIONS WILL BE IN ACCORDANCE WITH NC GUIDELINES. INSPECTIONS WILL BE PERFORMED AT LEAST ONCE PER 7
CALENDAR DAYS AND WITHIN 24 HOURS OF A RAINFALL EVENT GREATER THAN 0.5 INCHES PER 24 HOUR PERIOD. THE DEPARTMENT OF ENERGY, MINING, AND
LAND RESOURCES (DEMLR) MONITORING FORM WILL BE USED TO DOCUMENT INSPECTIONS.
TIMBER MATS
DETI UTILIZES CONSTRUCTION TIMBER MATS TO PROVIDE ACCESS THROUGH AREAS SUCH AS WETLANDS AND WATERBODIES, SOME AGRICULTURAL FIELDS,
STEEP SLOPES, AND OTHER AREAS AS DETERMINED BY THE CONSTRUCTION SUPERVISOR. THIS PRACTICE REDUCES SOIL COMPACTION AND PROVIDES A STABLE
TRAVEL LANE FOR CONTRACTORS ALONG THE PROJECT ROW, THUS MINIMIZING LAND DISTURBANCE. THE MATERIALS USED TO CONSTRUCT THE TIMBER
MATTING WILL BE ABLE TO WITHSTAND THE ANTICIPATED LOADING OF THE CONSTRUCTION TRAFFIC. THE TIMBER MATS OVER WATERBODY CROSSINGS WILL
BE CLEANED AT THE END OF EACH DAY AND WHERE EXCESS ACCUMULATION OF SEDIMENT THE TIMBER MATS WILL BE CLEANED OFF THROUGHOUT EACH DAY.
THE USE OF CONSTRUCTION TIMBER MAY GENERALLY NOT CONSTITUTE SOIL DISTURBANCE OR A CHANGE IN HYDROLOGY. THEREFORE, THE INSTALLATION OF
TIMBER MAT ACCESS ROADS AND WORK PADS IS NOT CONSIDERED A REGULATED LAND -DISTURBING ACTIVITY.
TRENCH PLUGS/BREAKERS
TRENCH PLUGS WILL BE USED AT ALL STREAM, RIVER, WETLAND OR OTHER WATERBODY CROSSINGS, AS NECESSARY, TO PREVENT DIVERSION OF WATER INTO
UPLAND PORTIONS OF THE PIPELINE TRENCH AND TO KEEP ANY ACCUMULATED TRENCH WATER OUT OF THE WATERBODY. TOPSOIL WILL NOT BE USED TO FILL
SACKS FOR TRENCH PLUGS. TRENCH PLUGS WILL BE OF SUFFICIENT SIZE TO WITHSTAND UPSLOPE WATER PRESSURE.
30. PERMANENT SACKS OF SUBSOIL OR SAND, POLYURETHANE FOAM, BENTONITE CLAY, OR POSSIBLY CEMENT (IN AREAS OF STEEP TERRAIN) BAGS INSTALLED
AROUND THE PIPE WILL REMAIN IN THE TRENCH TO PREVENT SUBSURFACE CHANNELING OF WATER ALONG THE TRENCH. TOPSOIL WILL NOT BE USED IN
TRENCH BREAKERS. TRENCH BREAKERS ARE NOT EMPLOYED IN TRENCHLESS PIPELINE CONSTRUCTION SUCH AS HORIZONTAL DIRECTIONAL DRILL (HDD) OR
FOR NON-LINEAR FACILITIES (E.G., COMPRESSOR STATIONS, M&R STATIONS).
31. THE NEED FOR AND SPACING OF TRENCH BREAKERS WILL BE INDICATED ON THE CONSTRUCTION ALIGNMENT SHEETS. TRENCH BREAKERS WILL BE
INSTALLED AT THE SAME SPACING AS AND UPSLOPE OF PERMANENT SLOPE BREAKERS UNLESS DETERMINED OTHERWISE BY THE CERTIFYING PROFESSIONAL
ENGINEER.
32. IN AGRICULTURAL FIELDS AND RESIDENTIAL AREAS WHERE SLOPE BREAKERS ARE NOT TYPICALLY REQUIRED, TRENCH BREAKERS WILL BE INSTALLED AT
THE SAME SPACING AS IF PERMANENT SLOPE BREAKERS WERE REQUIRED. IN AGRICULTURAL LANDS, TRENCH BREAKERS WILL BE INSTALLED TO A DEPTH
THAT DOES NOT ENCROACH INTO THE TYPICAL PLOW ZONE.
PERMANENT TRENCH BREAKERS WILL BE INSTALLED AT THE BASE OF SLOPES GREATER THAN 5 PERCENT WHERE THE BASE OF THE SLOPE IS LESS THAN 50 FEET
FROM A WATERBODY OR WETLAND AND WHERE NEEDED TO AVOID DRAINING A WATERBODY OR WETLAND.
TURBIDITY CURTAINS
TURBIDITY CURTAINS WILL BE INSTALLED DOWNSTREAM OF THE STREAM CROSSING AS NECESSARY TO MINIMIZE SUSPENDED SOLIDS IN THE WATER.
1. A TYPE I OR II CURTAIN WILL BE SELECTED BASED ON THE FLOW CONDITION. IN MOST SITUATIONS, TURBIDITY CURTAINS SHOULD NOT BE INSTALLED ACROSS
CHANNEL FLOWS.
2. TURBIDITY CURTAINS WILL EXTEND THE ENTIRE DEPTH OF THE WATERCOURSE WHEN THE WATERCOURSE IS NOT SUBJECT TO TIDAL ACTION AND/OR
SIGNIFICANT WIND AND WAVE FORCES.
3. IN TIDAL AND/OR WIND AND WAVE ACTION SITUATIONS, THE CURTAIN WILL NEVER TOUCH THE BOTTOM. THE CURTAIN WILL HAVE A MINIMUM 1 -FOOT GAP
BETWEEN THE WEIGHTED LOWER END OF THE SKIRT AND THE BOTTOM AT "MEAN" LOW WATER.
4. IN TIDAL AND/OR WIND AND WAVE ACTION SITUATIONS, THE CURTAIN DEPTH WILL NOT BE LOWER THAN 10 T012 FEET BELOW THE SURFACE.
5. TURBIDITY CURTAINS WILL BE LOCATED PARALLEL TO THE DIRECTION OF FLOW OF A MOVING WATERBODY.
6. A MINIMUM CONTINUOUS SPAN OF 50 FEET BETWEEN JOINTS AND A MAXIMUM SPAN OF 100 FEET BETWEEN JOINTS (ANCHOR OR STAKE LOCATIONS) IS A
GOOD RULE OF THUMB.
7. THE ENDS OF THE CURTAIN SHOULD EXTEND WELL UP TO THE SHORELINE AND SECURED FIRMLY TO THE SHORELINE, PREFERABLY TO RIGID BODIES SUCH AS
TREES OR PILES.
8. WHEN THERE IS SPECIFIC NEED TO EXTEND THE CURTAIN TO THE BOTTOM OF THE WATERCOURSE IN TIDAL OR MOVING WATER CONDITIONS, A HEAVY
WOVEN PERVIOUS FILTER FABRIC MAY BE SUBSTITUTED FOR THE NORMALLY RECOMMENDED IMPERVIOUS GEOTEXTILE.
9. BARRIERS WILL BE OF BRIGHT COLORS TO ATTRACT THE ATTENTION OF NEARBY BOATERS.
10. SEAMS IN THE FABRIC WILL BE EITHER VULCANIZED WELDED OR SEWN AND WILL DEVELOP THE FULL STRENGTH OF THE FABRIC.
11. THE LOAD LINES WILL BE FABRICATED INTO THE BOTTOM OF ALL FLOATING CURTAINS. TYPE -II AND III MUST HAVE LOAD LINES ALSO FABRICATED INTO
THE TOP OF THE FABRIC.
12. EXTERNAL ANCHORS MAY CONSIST OF WOODEN OR METAL STAKES FOR TYPE I CURTAINS; TYPE -II AND III SHOULD USE BOTTOM ANCHORS.
13. ONCE THE CURTAIN IS NO LONGER REQUIRED, AS DETERMINED BY THE EI, THE CURTAIN AND RELATED COMPONENTS WILL BE REMOVED IN SUCH A
MANNER AS TO MINIMIZE TURBIDITY. SEDIMENT MAY BE REMOVED AND THE ORIGINAL DEPTH RESTORED. ANY SPOILS WILL BE TAKEN TO AN UPLAND AREA
AND STABILIZED.
TRENCH DEWATERING
DETI UTILIZES GEOTEXTILE BAGS FOR DEWATERING AND VELOCITY REDUCTION ON A MAJORITY OF PIPELINE CONSTRUCTION PROJECTS. THE PURPOSE,
DEFINITION, CONDITIONS OF APPLICATION AND PLANNING CONSIDERATIONS ARE IDENTICAL. DESIGN CRITERIA AND SPECIFICATIONS VARY BY DEWATERING
BAG MANUFACTURER; A VARIETY OF GEOTEXTILE DEWATERING BAG PRODUCTS ARE AVAILABLE ON THE MARKET. THE MANUFACTURERS' GUIDANCE ON THE
USE, DESIGN, SIZING, MAINTENANCE, AND APPLICATION OF THE GEOTEXTILE DEWATERING BAG WILL BE FOLLOWED.
14. CONDUCT DEWATERING (ON OR OFF THE CONSTRUCTION ROW) IN SUCH A MANNER THAT DOES NOT CAUSE EROSION AND DOES NOT RESULT IN
SILT -LADEN WATER FLOWING INTO ANY WATERBODY, WETLAND, OR OFF-SITE PROPERTY.
15. ELEVATE AND SCREEN THE INTAKE OF EACH HOSE USED TO WITHDRAW THE WATER FROM THE TRENCH TO MINIMIZE PUMPING OF DEPOSITED
SEDIMENTS.
16. A DEWATERING BAG MAY NOT BE NEEDED IF THERE IS A WELL -STABILIZED, VEGETATED AREA ON SITE TO WHICH WATER CAN BE DISCHARGED. THE AREA
MUST BE STABILIZED SO THAT IT CAN FILTER SEDIMENT AND AT THE SAME TIME WITHSTAND THE VELOCITY OF THE DISCHARGED WATER WITHOUT ERODING.
A MINIMUM FILTERING LENGTH OF 75 FEET MUST BE AVAILABLE IN ORDER FOR SUCH A METHOD TO BE FEASIBLE.
17. REMOVE DEWATERING STRUCTURES AS SOON AS PRACTICABLE AFTER THE COMPLETION OF DEWATERING ACTIVITIES, IF SEDIMENT BUILD-UP PREVENTS
THE BAG FROM FUNCTIONING PROPERLY, OR THE BAG BECOMES HALF FULL OF SEDIMENT, DISCARD AND REPLACE WITH A NEW BAG.
WATERBARS (TEMPORARY/PERMANENT)
18. TEMPORARY WATERBARS WILL BE INSTALLED PRIOR TO PIPELINE INSTALLATION.
19. PERMANENT WATERBARS WILL BE INSTALLED AT THE COMPLETION OF PIPELINE INSTALLATION.
20. WATERBARS WILL BE INSTALLED IN ACCORDANCE WITH NC EROSION AND SEDIMENT CONTROL SPECIFICATIONS.
STREAM BANK STABILIZATION AT PIPE COMPLETION
21. EROSION CONTROL MATTING SHALL BE PLACED ON THE BANKS OF THE FLOWING STREAMS WHERE VEGETATION HAS BEEN REMOVED OR AS DIRECTED BY
THE EI.
22. EROSION CONTROL MATTING SHALL MEET THE REQUIREMENTS SPECIFIED IN THE PLAN.
23. STAPLES SHALL BE MADE OF AT LEAST 11 GAUGE WIRE, U -SHAPED WITH 6" LEGS AND A 1" CROWN. STAPLES SHALL BE DRIVEN INTO THE GROUND FOR
THE FULL EFFECT OF THE STAPLE LEGS. ALTERNATIVELY, 1" DIA. WOODEN PEGS 6" LONG AND BEVELED MAY BE USED TO SECURE MATTING.
24. MATTING SHALL BE INSTALLED PER MANUFACTURERS SPECIFICATIONS OR AS STATED BELOW:
25. EXTEND TOP OF BLANKET 2 FEET PAST THE UPPER EDGE OF THE HIGH WATER MARK. IF A SLOPE BREAKER IS PRESENT, ON THE APPROACH SLOPE, BEGIN
THE BLANKET ON THE UPHILL SIDE OF THE SLOPE BREAKER.
26. INSTALL BLANKETS ACROSS THE SLOPE IN THE DIRECTION OF THE WATER FLOW.
27. ANCHOR THE UPSTREAM EDGE OF THE BLANKET INTO THE SLOPE USING A 6" DEEP TRENCH, DOUBLE STAPLE EVERY 12" BEFORE BACKFILLING AND
COMPACTING TRENCH.
28. OVERLAP THE EDGES OF PARALLEL BLANKETS A MINIMUM OF 6". PLACE THE UPPER BLANKET OVER THE LOWER BLANKET (SHINGLE STYLE) AND STAPLE

ACCESS ROADS
DETI HAS IDENTIFIED ROADS WHICH WILL BE USED TO PROVIDE ACCESS TO THE PROPOSED ACP PIPELINE ROW AND OTHER FACILITIES DURING CONSTRUCTION AND OPERATION OF THE PROJECTS. IN SOME
CASES, EXISTING ROADS WILL REQUIRE IMPROVEMENT (SUCH AS GRADING, GRAVELLING, REPLACING CULVERTS, MINOR WIDENING, AND/OR CLEARING OF OVERHEAD VEGETATION) TO SAFELY ACCOMMODATE
CONSTRUCTION EQUIPMENT AND VEHICLES. DETI ACCESS ROAD LOCATIONS ARE SHOWN ON THE CONSTRUCTION ALIGNMENT SHEETS. TRAFFIC MANAGEMENT PLANS HAVE BEEN DEVELOPED FOR THE
PROPOSED PROJECT AND WILL BE IMPLEMENTED AND FOLLOWED DURING CONSTRUCTION TO REDUCE IMPACT TO TRAFFIC FLOW. IT IS ANTICIPATED THE PROPOSED PROJECT WILL NOT IMPACT ROADS OR
TRAFFIC DURING THE CONSTRUCTION AND OPERATION OF THE PROJECT.
A CONSTRUCTION ENTRANCE WILL BE CONSTRUCTED AT ANY POINT WHERE CONSTRUCTION EQUIPMENT LEAVES THE ROW AND ENTERS A PAVED PUBLIC ROAD OR OTHER PAVED SURFACE. TYPICALLY, A
CONSTRUCTION ENTRANCE IS COMPRISED OF FILTER FABRIC OVERLAIN BY 6 INCHES OF COARSE AGGREGATE EXTENDING A MINIMUM OF 100 FEET FROM THE EDGE OF THE PAVEMENT. THE AREA OF THE
ENTRANCE MUST BE EXCAVATED 3 -INCHES PRIOR TO LAYING THE FILTER FABRIC UNDERLINER. THE ENTRANCE MUST EXTEND THE FULL WIDTH OF THE VEHICULAR INGRESS AND EGRESS AREA AND HAVE A
MINIMUM 18 -FOOT WIDTH. CONVEYANCE OF SURFACE WATER THROUGH CULVERTS UNDER THE ENTRANCE WILL BE PROVIDED, AS NECESSARY.
THE CONSTRUCTION ENTRANCE MUST FUNCTION TO REMOVE MUD FROM VEHICLES AND EQUIPMENT LEAVING THE ROW. AS MUD ACCUMULATES ON THE ENTRANCE, CLEAN STONE MUST BE ADDED OR THE
TIRE MATS LIFTED AND SHAKEN TO REMOVE MUD. ANY MUD THAT IS CARRIED ONTO THE PAVEMENT MUST BE THOROUGHLY REMOVED BY THE END OF THE DAY BY SHOVELING OR SWEEPING. THE MUD WILL
BE RETURNED TO THE ROW. THE USE OF WATER TO REMOVE SEDIMENT TRACKED ONTO ROADWAYS IS PERMITTED ONLY AFTER SEDIMENT IS REMOVED AS STATED ABOVE.
MAINTENANCE OF THE CONSTRUCTION ENTRANCE MAY REQUIRE PERIODIC TOP DRESSING WITH ADDITIONAL STONE AND CLEANOUT OF ANY STRUCTURES USED TO TRAP SEDIMENT. ADDITIONALLY, THE
CONSTRUCTION ENTRANCE MAY NEED TO BE SHOVELED THEN SWEPT, FOLLOWED BY WASHING OF THE ENTRANCE TO REMOVE ANY SEDIMENT BUILD UP. IF ANY INADVERTENTLY SEDIMENT TRACKING OCCURS
ON THE PUBLIC ROADWAY, THE ROAD WILL BE CLEANED THOROUGHLY BY THE END OF EACH DAY.
DETI HAS IDENTIFIED BOTH PRIVATE AND PUBLIC ROADS WHICH WILL BE USED TO PROVIDE ACCESS TO THE PROPOSED ACP PIPELINE ROW AND OTHER FACILITIES DURING CONSTRUCTION AND OPERATION OF
THE PROJECT. IN -SOME CASES, EXISTING ROADS WJ L_RE0,WE IMP_RQV,EMENT�SUC+AS GRADING, GRAVELLJN-GREP-LAGWG NSTALLING COL-VE,RTS, MINOR DEN NG, AND/ CLE G O ERHEAD
VEGETATION) TO SAFELY ACCOMMODATE CONSTRUCTI IN EQUIPMENT AND VEHICLES. THE FOLLOWING C'ONDITIONS APPLY TO THE USE OF ACCESS ItOADS7
• THE PROJECT WILL UTILIZE EXISTING ROADS FOR ACCESS. NO NEW ACCESS ROADS AND/OR ROADSIDE DITCHES ARE BEING CONSTRUCTED. IMPROVEMENTS TO ACCESS ROADS MAY INCLUDE PLACEMENT OF
STONE FOR ALL WEATHER ACCESS AND DURABILITY. EXISTING ROADSIDE DITCHES WILL NOT BE DISTURBED.
• CONSTRUCTION ENTRANCES WILL HAVE STONE ACCESS ENTRANCE AND EXIT DRIVES AND PARKING AREAS TO REDUCE THE TRACKING OF SEDIMENT ONTO PUBLIC OR PR VATE ROADS. CONSTRUCTION
NTRAN�-WILL BE CONSTRUCTEbAT-ANY POINT WHERE CONSTRUCTION EQUIPMENT -LEAVES THE ROW AND ENTERS A PAVED PUBLIC ROAD OR OTHER PAVED SURFACE.
• DURING CONSTRUCTION AND RESTORATION ACTIVITIES, ACCESS TO THE ROW IS LIMITED TO THE USE OF NEW OR EXISTING ACCESS ROADS IDENTIFIED ON THE CONSTRUCTION ALIGNMENT SHEETS.
• TO THE EXTENT POSSIBLE, ACCESS THROUGH WETLANDS WILL BE LIMITED TO THE CONSTRUCTION ROW AND THOSE EXISTING ROADS REQUIRING NO MODIFICATION OR IMPROVEMENTS, OTHER THAN
ROUTINE REPAIR, AND POSING NO IMPACT ON THE WETLAND.
• THE CONSTRUCTION ROW MAY BE USED FOR ACCESS ACROSS WETLANDS WHEN THE WETLAND SOIL IS FIRM ENOUGH TO AVOID RUTTING OR THE CONSTRUCTION ROW HAS BEEN APPROPRIATELY STABILIZED
TO AVOID RUTTING (E.G., TIMBER MATTING). HOWEVER, ACCESS IS NOT ALLOWED THROUGH WETLANDS THAT WOULD NOT OTHERWISE BE IMPACTED BY THE PROJECT.
• IN WETLANDS THAT CANNOT BE APPROPRIATELY STABILIZED, ALL CONSTRUCTION EQUIPMENT OTHER THAN THAT NEEDED TO INSTALL THE WETLAND CROSSING WILL USE ACCESS ROADS LOCATED IN
UPLAND AREAS. WHERE ACCESS ROADS IN UPLAND AREAS DO NOT PROVIDE REASONABLE ACCESS, LIMIT ALL OTHER CONSTRUCTION EQUIPMENT TO ONE PASS THROUGH THE WETLAND USING THE
CONSTRUCTION ROW.
• MAINTAIN SAFE AND ACCESSIBLE CONDITIONS AT ALL ROAD CROSSINGS AND ACCESS POINTS DURING CONSTRUCTION AND RESTORATION. ACCESS ROAD MAINTENANCE THROUGH THE CONSTRUCTION
SEQUENCE MAY INCLUDE GRADING AND THE ADDITION OF GRAVEL OR STONE WHEN NECESSARY.
• MAINTAIN ACCESS ROADS IN A STABLE MANNER TO PREVENT OFF -ROW IMPACTS, INCLUDING IMPACTS TO ADJACENT AND/OR NEARBY SENSITIVE RESOURCE AREAS, AND IMPLEMENT ALL APPROPRIATE ESC
MEASURES FOR CONSTRUCTION/IMPROVEMENT OF ACCESS ROADS.
• IF EROSION IS OBSERVED ADJACENT TO ACCESS ROADS, IMMEDIATELY REPAIR, STABILIZE, OR IMPLEMENT ADDITIONAL ESC MEASURES. ADDITIONAL MEASURES INCLUDE SILT FENCE, CHECK DAMS, OR
EROSION CONTROL FABRIC. THE EI WILL IMPLEMENTTHE APPROPRIATE ESC MEASURE BASED UPON OBSERVED SITE CONDITIONS.
• MINIMIZE THE USE OF TRACKED EQUIPMENT ON PUBLIC ROADWAYS AND IN ACCORDANCE WITH REQUIREMENTS OF THE MANAGING AGENCY.
• REMOVE ANY SOIL OR GRAVEL SPILLED OR TRACKED ONTO ROADWAYS DAILY OR MORE FREQUENT AS NECESSARY TO MAINTAIN SAFE ROAD CONDITIONS.
• REPAIR ANY DAMAGES TO ROADWAY SURFACES, SHOULDERS, AND BAR DITCHES.
• IF CRUSHED STONE/ROCK ACCESS PADS ARE USED IN RESIDENTIAL OR AGRICULTURAL AREAS, STONE WILL BE PLACED ON SYNTHETIC, NONWOVEN GEOTEXTILE FABRIC TO FACILITATE REMOVAL AFTER
CONSTRUCTION.
• ALL ACCESS ROADS ACROSS A WATERBODY MUST USE AN EQUIPMENT BRIDGE.
• FOR ACCESS THROUGH A SATURATED WETLAND, USE TIMBER MATS OR AN EQUIVALENT UNLESS OTHERWISE AUTHORIZED BY AGENCY PERMITS.
• LIMIT CONSTRUCTION EQUIPMENT OPERATING IN WETLAND AREAS TO THAT NEEDED TO CLEAR THE ROW, DIG THE TRENCH, FABRICATE AND INSTALL THE PIPELINE, BACKFILL THE TRENCH, AND RESTORE THE
CONSTRUCTION ROW. ALL OTHER CONSTRUCTION EQUIPMENT WILL USE ACCESS ROADS LOCATED IN UPLAND AREAS TO THE MAXIMUM EXTENT PRACTICAL.
• ROADS WILL BE SURFACED WITH STONE OR ANOTHER SUITABLE MATERIAL TO PROVIDE A NON -ERODIBLE RUNNING SURFACE.
• CUT -BANKS AND FILL -SLOPES WILL BE STABILIZED SHOULD BE STABILIZED ACCORDING TO THE STABILIZATION GUIDELINGS SHOWN ON SHEET 7.
• SILT FENCE OR STONE OUTLET PROTECTION WILL BE CONSTRUCTED AT OUTLETS OF DRAINAGE STRUCTURES.
• WHEN ACCESS ROADS INTERSECT PUBLIC HIGHWAYS, THE CONTRACTOR WILL USE A COMBINATION OF GEOTEXTILE AND STONE (TEMPORARY STONE CONSTRUCTION ENTRANCE) TO HELP KEEP MUD OFF
HIGHWAY ENTRANCES. WHERE SEDIMENT IS TRANSPORTED ONTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD SURFACE WILL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT WILL BE
REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING WILL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS
MANNER.
• ROADS WILL BE MAINTAINED SO THAT WATER CAN FLOW FREELY FROM THE ROAD SURFACE.
• TEMPORARY ACCESS ROADS WILL FOLLOW EXISTING CONTOURS AS MUCH AS POSSIBLE

HORIZONTAL DIRECTIONAL DRILL (HDD)
5o/

EXISTING GROUND
THE HDD METHOD IS A PROCESS THAT ALLOWS FOR TRENCHLESS CONSTRUCTION BY DRILLING A HOLE BENEATH A SURFACE FEATURE, SUCH AS A WATERBODY OR OTHER UNIQUE RESOURCE, AND INSTALLING A PREFABRICATED SEGMENT OF
PIPELINE THROUGH THE HOLE. THE METHOD AVOIDS DISTURBANCE TO THE SURFACE OF THE ROW BETWEEN THE ENTRY AND EXIT POINTS OF THE DRILL. THE METHOD IS SOMETIMES USED TO INSTALL PIPELINES UNDERNEATH SENSITIVE
RESOURCES OR AREAS THAT PRESENT DIFFICULTIES ASSOCIATED WITH CONSTRUCTION OR ACCESS USING TYPICAL INSTALLATION METHODS. HDDS CAN PROVIDE CERTAIN ADVANTAGES OVER TYPICAL CONSTRUCTION METHODS, SUCH AS
AVOIDANCE OF SURFACE DISTURBANCE, RIPARIAN TREE CLEARING, OR IN -STREAM CONSTRUCTION.
FOR EACH HDD CROSSING, ELECTRIC GRID GUIDE WIRES WILL BE LAID BY HAND ON THE GROUND ALONG THE PIPELINE CENTERLINE TO CREATE AN ELECTROMAGNETIC SENSOR GRID. THE GRID WILL BE USED BY THE HDD OPERATOR TO STEER
THE DRILL HEAD DURING DRILLING. NO GROUND OR SURFACE DISTURBING ACTIVITIES WILL BE REQUIRED FOR INSTALLATION OF THE GUIDE WIRES. IN THICKLY VEGETATED AREAS, HOWEVER, A SMALL PATHWAY MEASURING APPROXIMATELY
2 TO 3 FEET IN WIDTH MAY NEED TO BE CUT WITH HAND TOOLS TO CREATE A PATH FOR THE WIRES.
TO COMPLETE EACH HDD, A DRILL RIG WILL BE PLACED ON THE ENTRY SIDE OF THE CROSSING AND A SMALL -DIAMETER PILOT HOLE WILL BE DRILLED ALONG A PREDETERMINED PATH BENEATH THE WATERBODY USING A POWERED DRILL BIT.
AS DRILLING PROGRESSES, ADDITIONAL SEGMENTS OF DRILL PIPE WILL BE INSERTED INTO THE PILOT HOLE TO EXTEND THE LENGTH OF THE DRILL. THE DRILL BIT WILL BE STEERED AND MONITORED THROUGHOUT THE PROCESS TO MAINTAIN
THE DESIGNATED PATH OF THE PILOT HOLE. ONCE THE PILOT HOLE IS COMPLETE, THE ELECTRIC SENSOR GRID WILL BE REMOVED AND THE HOLE WILL BE ENLARGED TO ACCEPTTHE PIPELINE.
TO ENLARGE THE PILOT HOLE, A LARGER REAMING TOOL WILL BE ATTACHED TO THE END OF THE DRILL ON THE EXIT SIDE OF THE HOLE. THE REAMER WILL BE DRAWN BACK THROUGH THE PILOT HOLE TO THE DRILL RIG ON THE ENTRY SIDE OF
THE HOLE. DRILL PIPE SECTIONS WILL BE ADDED TO THE REAR OF THE REAMER AS IT PROGRESSES TOWARD THE RIG, ALLOWING A STRING OF DRILL PIPE TO REMAIN IN THE HOLE AT ALLTIMES. SEVERAL PASSES WITH PROGRESSIVELY LARGER
REAMING TOOLS WILL BE REQUIRED TO ENLARGE THE HOLE TO A SUFFICIENT DIAMETER TO ACCOMMODATE THE PIPELINE. THE FINAL HOLE WILL BE APPROXIMATELY 12 INCHES LARGER THAN THE PIPELINE TO BE INSTALLED.
THROUGHOUT THE DRILLING PROCESS, A FLUID MIXTURE CONSISTING OF WATER AND BENTONITE CLAY (A NATURALLY OCCURRING MINERAL) WILL BE PUMPED INTO THE DRILL HOLE TO LUBRICATE THE BIT, TRANSPORT CUTTINGS TO THE
SURFACE, AND MAINTAIN THE INTEGRITY OF THE HOLE. WATER FOR THE MIXTURE WILL BE PUMPED FROM THE WATERBODY TO THE DRILL SITE THROUGH A HOSE OR TEMPORARY NETWORK OF IRRIGATION -TYPE PIPING OR TRUCKED IN FROM
ANOTHER SOURCE. THE PUMP INTAKE WILL BE APPROPRIATELY SCREENED TO PREVENT ENTRAINMENT OF AQUATIC SPECIES. SMALL PITS WILL BE DUG AT OR NEAR THE ENTRY AND EXIT POINTS FOR THE HDD TO TEMPORARILY STORE THE
DRILLING FLUID AND CUTTINGS. THE FLUID AND CUTTINGS WILL BE PUMPED FROM THE PITS TO AN ON-SITE RECYCLING UNIT WHERE THE FLUID WILL BE PROCESSED FOR REUSE.
THE PIPELINE SEGMENT (ALSO CALLED A PULL SECTION) TO BE INSTALLED BENEATH THE SURFACE FEATURE WILL BE FABRICATED ON THE ROW OR IN THE ADDITIONAL TEMPORARY WORK SPACE (ATWS) ON THE EXIT SIDE OF THE CROSSING
WHILE THE DRILL HOLE IS REAMED TO SIZE. THE PULL SECTION WILL BE INSPECTED AND HYDROSTATICALLY TESTED PRIOR TO INSTALLATION.
AS THE PIPELINE IS BEING INSTALLED, EXCESS DRILLING FLUID WILL BE COLLECTED AND INCORPORATED INTO THE SOIL IN AN UPLAND AREA OR DISPOSED OF AT AN APPROPRIATE FACILITY. IF WATER IS LEFT OVER FROM THE DRILLING
PROCESS, IT WILL BE DISCHARGED INTO A WELL -VEGETATED UPLAND AREA OR AN ENERGY DISSIPATION/SEDIMENT FILTRATION DEVICE, SUCH AS A GEOTEXTILE FILTER BAG, IN A MANNER THAT DOES NOT AFFECT FLOWING STREAMS OR
OFF-SITE PROPERTY.
IF AN HDD CROSSING IS SUCCESSFUL, THERE ARE LITTLE TO NO IMPACTS ON THE SURFACE FEATURE BEING CROSSED. IF A NATURAL FRACTURE OR WEAK AREA IN THE GROUND IS ENCOUNTERED DURING DRILLING, HOWEVER, AN
INADVERTENT RETURN OF DRILLING FLUID TO THE ENVIRONMENT COULD OCCUR. SUBSTRATE CONSISTING OF UNCONSOLIDATED GRAVEL, COARSE SAND, OR FRACTURED BEDROCK COULD PRESENT CIRCUMSTANCES THAT INCREASE THE
LIKELIHOOD OF AN INADVERTENT RETURN. DEPENDING ON THE ORIENTATION OF THE NATURAL FRACTURE OR SUBSTRATE, THE DRILLING FLUID MAY MOVE LATERALLY OR VERTICALLY FROM THE DRILL HOLE. IF THE DRILLING FLUID MOVES
LATERALLY, THE RELEASE MAY NOT BE EVIDENT ON THE GROUND. FOR AN INADVERTENT RETURN TO BE EVIDENT ON THE SURFACE, THERE MUST BE A PREFERENTIAL PATHWAY EXTENDING VERTICALLY FROM THE DRILL HOLE TO THE SURFACE
OF THE GROUND. THE VOLUME OF FLUID RELEASED IN AN INADVERTENT RETURN IS DEPENDENT ON A NUMBER OF FACTORS, INCLUDING THE SIZE OF THE PATHWAY, THE PERMEABILITY OF THE GEOLOGIC MATERIAL, THE VISCOSITY OF THE
FLUID, AND THE PRESSURE OF THE HYDRAULIC DRILLING SYSTEM.
DETI'S HORIZONTAL DIRECTIONAL DRILL FLUID MONITORING, OPERATIONS, AND CONTINGENCYPLAN (HDD PLAN), IDENTIFIES TYPICAL CONTINGENCY MEASURES TO BE IMPLEMENTED IN THE EVENT OF A DRILL FAILURE, SUCH AS DRILLING
ALONG A NEW PATH, ABANDONING AND SEALING THE DRILL HOLE, AND IMPLEMENTING AN ALTERNATE CROSSING METHOD, AND DESCRIBES THE PROCEDURES TO BE FOLLOWED IN THE EVENT OF AN INADVERTENT RETURN OF DRILLING
FLUID. IF A RELEASE OCCURS ON LAND, INCLUDING WITHIN A WETLAND, A SMALL PIT WILL BE EXCAVATED AT THE RELEASE SITE TO CONTAIN THE SPREAD OF THE FLUID, AND A PUMP WILL BE USED TO TRANSFER THE FLUID FROM THE PIT
INTO A CONTAINMENT VESSEL. IF AN INADVERTENT RETURN OCCURS INA WATERBODY, IT WILL BE MORE DIFFICULT TO CONTAIN BECAUSE THE FLUID WILL BE DISPERSED INTO THE WATER AND CARRIED DOWNSTREAM. IN THIS SITUATION,
AN ATTEMPT WILL BE MADE TO PLUG THE FLOW PATH BY ADDING THICKENING AGENTS TO THE DRILLING FLUID, SUCH AS ADDITIONAL BENTONITE, COTTONSEED HULLS, OR OTHER NON -HAZARDOUS MATERIALS. DETI WILL CONSULT WITH
AND OBTAIN PERMISSION FROM THE APPROPRIATE STATE REGULATORY AGENCIES REGARDING THE USE OF ADDITIVES DURING THE HDD (OR CONVENTIONAL BORE) PROCESS, AND CONFIRM THAT ADDITIVES WILL NOT VIOLATE WATER
QUALITY STANDARDS.
