NATIVE VEGETATIONSARE DIFFICULT TO MANAGE AND TAKE LONGER TO ESTABLISH. MONITOR THE SITE UNTIL LONGTERM STABILITY HAS BEEN ESTABLISHED.RIPARIAN SEEDBED PREPARATION1.Disturbed soils within riparian areas must be amended to provide an optimum environment for seedgermination and seedling growth. The surface soil must be loose enough for water infiltration and rootpenetration. The pH of the soil must be such that it is not toxic and nutrients are available. Riparian areas aregenerally considered rich in nutrients due to flooding and deposition, however, these areas can be highlyvariable (i.e., narrow steep corridors in the mountains, artificial fill material on top of alluvial floodplains in thePiedmont). Soil analysis should be performed to determine nutrient and lime needs of each site. Appropriatelevels of phosphorus and potassium are critical for permanent seed establishment. Appropriate pH levels arebetween 5.5 and 7. Riparian buffers regulated for nutrient management may be limited to a single applicationof fertilizer. Construction activities within the riparian area can greatly compact soils. Suitable mechanicalmeans such as disking, raking, or harrowing must be employed to loosen the compacted soil prior toseeding.SEEDING AND MULCHINGSEE SEED MIXES, SOIL AMENDMENTS, AND MULCHSPECIFICATIONS SPECIFIED IN THE ACPRESTORATION AND REHABILITATION PLAN.1.SEEDBED PREPARATION: AREAS TO BE SEEDEDSHALL BE DISKED TO A DEPTH OF 4-IN TO 6-INWHENEVER FEASIBLE, AND SMOOTHLY GRADED.2.IN TOPSOILED AREAS, SOIL TO BEREDISTRIBUTED EVENLY AND STABILIZED PRIORTO SEEDING.3.STABILIZATION MEASURES SHALL BE INITIATEDAS SOON AS PRACTICABLE IN PORTIONS OF THESITE WHERE CONSTRUCTION ACTIVITIES HAVETEMPORARILY OR PERMANENTLY CEASED, BUTIN NO CASE MORE THAN 21 DAYS AFTER THECONSTRUCTION ACTIVITY IN THAT PORTION OFTHE SITE HAS PERMANENTLY CEASED.4.WHERE THE INITIATION OF STABILIZATIONMEASURES WITHIN 7 DAYS AFTERCONSTRUCTION ACTIVITY TEMPORARILY ORPERMANENTLY CEASES IS PRECLUDED BYSNOW COVER, STABILIZATION MEASURES SHALLBE INITIATED AS SOON AS CONDITIONS ALLOW.5.WHERE CONSTRUCTION ACTIVITY WILL RESUMEON A PORTION OF THE SITE WITHIN 21 DAYSFROM WHEN ACTIVITIES CEASED (E.G., THETOTAL TIME PERIOD THAT CONSTRUCTIONACTIVITY IS TEMPORARILY HALTED IS LESS THAN14 DAYS), THEN STABILIZATION MEASURES DONOT HAVE TO BE INITIATED ON THAT PORTIONOF THE SITE BY THE SEVENTH DAY AFTERCONSTRUCTION ACTIVITIES HAVE TEMPORARILYCEASED.6.AREAS WHERE THE SEED HAS FAILED TOGERMINATE ADEQUATELY (UNIFORM PERENNIALVEGETATIVE COVER WITH A DENSITY OF 80%)WITHIN 30 DAYS, SEEDING AND MULCHING MUSTBE RE-SEEDED IMMEDIATELY, OR AS SOON ASWEATHER PERMITS.7-1017-102GENERAL NOTES AND COMMENTS:SYM.DATEBYREVISION INFORMATIONPROJECT/TASKAPP.--ISSUED FOR PERMITTINGJR03/09./20170APP.

WHERE SEDIMENT IS TRANSPORTED ONTO A PAVED OR PUBLIC ROAD SURFACE, THE ROAD SURFACE WILL BE CLEANED THOROUGHLY AT THE ENDOF EACH DAY. SEDIMENT WILL BE REMOVED FROM THE ROADS BY SHOVELING OR SWEEPING AND TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING WILL BEALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER.26.ROADS WILL BE MAINTAINED SO THAT WATER CAN FLOW FREELY FROM THE ROAD SURFACE.27.TEMPORARY ACCESS ROADS WILL FOLLOW EXISTING CONTOURS AS MUCH AS POSSIBLEHORIZONTAL DIRECTIONAL DRILL (HDD)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 OFPIPELINE 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 SENSITIVERESOURCES OR AREAS THAT PRESENT DIFFICULTIES ASSOCIATED WITH CONSTRUCTION OR ACCESS USING TYPICAL INSTALLATION METHODS. HDDS CAN PROVIDE CERTAIN ADVANTAGES OVER TYPICAL CONSTRUCTION METHODS, SUCH ASAVOIDANCE 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 STEERTHE 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 APPROXIMATELY2 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 MAINTAINTHE 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 ACCEPT THE 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 OFTHE 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 ALL TIMES. SEVERAL PASSES WITH PROGRESSIVELY LARGERREAMING 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 THESURFACE, 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 FROMANOTHER 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 THEDRILLING 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 CROSSINGWHILE 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 DRILLINGPROCESS, 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 OROFF-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, ANINADVERTENT RETURN OF DRILLING FLUID TO THE ENVIRONMENT COULD OCCUR. SUBSTRATE CONSISTING OF UNCONSOLIDATED GRAVEL, COARSE SAND, OR FRACTURED BEDROCK COULD PRESENT CIRCUMSTANCES THAT INCREASE THELIKELIHOOD 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 MOVESLATERALLY, 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 SURFACEOF 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 THEFLUID, AND THE PRESSURE OF THE HYDRAULIC DRILLING SYSTEM.DETI'S HORIZONTAL DIRECTIONAL DRILL FLUID MONITORING, OPERATIONS, AND CONTINGENCY PLAN (HDD PLAN), IDENTIFIES TYPICAL CONTINGENCY MEASURES TO BE IMPLEMENTED IN THE EVENT OF A DRILL FAILURE, SUCH AS DRILLINGALONG 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 DRILLINGFLUID. 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 PITINTO A CONTAINMENT VESSEL. IF AN INADVERTENT RETURN OCCURS IN A 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 WITHAND 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 WATERQUALITY STANDARDS.PROPOSED PIPELINEMARKER (TYP)EXISTING GROUND13PROPOSED ACP 36" DIA.AP-2 STEEP PIPELINE1111INFLUENCE LINE(TYP.)50'50'10' MIN.5' MIN.5' MIN.ROAD CENTERLINE ℄DITCH ℄DITCH ℄EXISTING EOPEXISTING EOPVARIESVARIESLEGAL R/W LINELEGAL R/W LINE10' MIN.NOTES:1.BORE PITS ARE TO BE 15'X50'AND A MINIMUM OF 10' DEEP.2.BORE PITS ARE TO BE 18"BELOW THE BOTTOM OF PIPE.3.45° INFLUENCE LINES MUST BEMAINTAINED AT ALL ROADCROSSINGS.4.BORE PIT LOCATED WITHINR.O.W.EXISTING ROADMAINTENANCE NOTES:1.MAINTAIN ESC MEASURES (ASSHOWN ON THE ALIGNMENTSHEETS)2.BORE PIT SPOIL MATERIAL TO BESURROUNDED BY BSRF AT THECOMPLETION OF EACH WORKDAY.STOCKPILESTOCKPILEBSRF (AROUND STOCKPILE)BSRF (AROUND STOCKPILE)BSRF (AROUND BORE PIT, AS NEEDED)BSRF (AROUND STOCKPILE)BSRF (AROUND STOCKPILE)BSRF (AROUND BORE PIT, AS NEEDED)8-1018-1028-103BSRF WHERE INDICATED ONALIGNMENT SHEETSBSRF WHERE INDICATED ONALIGNMENT SHEETSGENERAL NOTES AND COMMENTS:SYM.DATEBYREVISION INFORMATIONPROJECT/TASKAPP.--ISSUED FOR PERMITTINGJR03/09./20170APP.

THE DAM-AND-PUMP METHOD IS ACCOMPLISHED BY UTILIZING PUMPS TOTRANSPORT STREAM FLOW ACROSS THE DISTURBED AREA. THIS METHOD INVOLVES PLACING SANDBAGS OR EQUIVALENT ACROSS THEEXISTING STREAM CHANNEL UPSTREAM FROM THE PROPOSED CROSSING TO STOP WATER FLOW AND DOWNSTREAM FROM THE CROSSING TOISOLATE THE WORK AREA. PUMPS ARE USED TO PUMP THE WATER ACROSS THE DISTURBED AREA AND BACK INTO THE STREAM FURTHERDOWNSTREAM.THE DAM-AND-PUMP PROCEDURE ALLOWS FOR MORE SPACE AND FLEXIBILITY DURING TRENCHING AND PIPE INSTALLATION, WHICH SHORTENSTHE DURATION OF TIME SPENT AT THE WATERBODY. THE DAM-AND-PUMP METHOD MAY BE USED FOR CROSSINGS OF WATERBODIES WHEREPUMPS CAN ADEQUATELY TRANSFER STREAM FLOW VOLUMES AROUND THE WORK AREA, AND WHERE THERE ARE NO CONCERNS ABOUTSENSITIVE SPECIES PASSAGE.1.THE DAM-AND-PUMP CROSSING METHOD WILL BE INSTALLED AS FOLLOWS:2.INSTALL AND PROPERLY SEAL SANDBAGS AT THE UPSTREAM AND DOWNSTREAM LOCATION OF THE CROSSING.3.CREATE AN IN-STREAM SUMP USING SANDBAGS IF A NATURAL SUMP IS UNAVAILABLE FOR THE INTAKE HOSE.4.INITIATE PUMPING OF THE STREAM AROUND THE WORK AREA PRIOR TO EXCAVATING THE TRENCH.5.MONITOR DAMS AND PUMPS AT ALL TIMES TO ENSURE PROPER OPERATION UNTIL THE WATERBODY CROSSING IS COMPLETED.6.REMOVE THE SANDBAG DAMS, PUMPS, AND HOSES AND RETURN NORMAL FLOW BACK TO THE WATERBODY FOLLOWING INSTALLATIONAND RESTORATION OF THE STREAMBED.7.IMPLEMENTATION OF THE DAM-AND-PUMP CROSSING METHOD WILL MEET THE FOLLOWING PERFORMANCE CRITERIA:8.USE SUFFICIENT PUMPS, INCLUDING ON-SITE BACKUP PUMPS, TO MAINTAIN DOWNSTREAM FLOWS.9.CONSTRUCT DAMS WITH MATERIALS THAT PREVENT SEDIMENT AND OTHER POLLUTANTS FROM ENTERING THE WATERBODY (E.G.,SANDBAGS OR CLEAN GRAVEL WITH PLASTIC LINER).10.SCREEN ALL INTAKE HOSES TO MINIMIZE THE ENTRAINMENT OF FISH AND OTHER AQUATIC LIFE.11.PREVENT STREAMBED SCOUR AT PUMP DISCHARGE.12.CONTINUOUSLY MONITOR THE DAM AND PUMPS TO ENSURE PROPER OPERATION THROUGHOUT THE WATERBODY CROSSING.WATER IMPOUNDMENTSDETI WILL UTILIZE ABOVEGROUND WATER IMPOUNDMENT STRUCTURES TO TEMPORARILY STORE WATER NEEDED FOR HYDROSTATIC TESTING.WATER FOR HYDROSTATIC TESTING WILL BE WITHDRAWN FROM ADJACENT SURFACE WATERS AND/OR MUNICIPAL SOURCES AND WILL BEPUMPED TO THE WATER IMPOUNDMENTS GRADUALLY OVER A 30- TO 90-DAY PERIOD WITHOUT IMPACTING DOWNSTREAM USERS OF WATER OREXCEEDING ALLOWABLE WATER WITHDRAWAL RATES. THE WATER IMPOUNDMENTS WILL BE CONSTRUCTED IN ATWS AND WILL BE CIRCULAR INCONFIGURATION WITH A DIAMETER OF APPROXIMATELY 190 FEET AND A HEIGHT OF APPROXIMATELY 15 FEET.OPEN-CUTTHE OPEN-CUT OR WET TRENCH CROSSING METHOD WILL INVOLVE TRENCHING THROUGH THE WATERBODY WHILE WATER CONTINUES TO FLOW THROUGH THE TRENCHING AREA.PRIOR TO INITIATING CONSTRUCTION ACROSS THE WATERBODY, THE CROSSING SECTION OF PIPELINE WILL BE FABRICATED (I.E., BENT, WELDED, AND COATED) IN ADJACENT ATWSAREAS. BACKHOE-TYPE EXCAVATORS WILL THEN BE USED TO EXCAVATE A TRENCH IN THE FLOWING WATERBODY FROM ONE OR BOTH BANKS OF THE WATERBODY. WHERE THEWATERBODY IS TOO WIDE TO EXCAVATE THE TRENCH FROM THE BANKS, EQUIPMENT MAY OPERATE FROM WITHIN THE WATERBODY WITH APPROVAL FROM THE APPROPRIATEREGULATORY AGENCIES. EQUIPMENT OPERATING WITHIN THE WATERBODY WILL BE LIMITED TO THAT NEEDED TO CONSTRUCT THE CROSSING. DURING THESE OPERATIONS, FLOWWILL BE MAINTAINED AT THE CROSSING AS SPECIFIED IN THE FERC PROCEDURES. TURBIDITY CURTAINS WILL BE INSTALLED DOWNSTREAM OF THE CROSSING AS NECESSARY TOMINIMIZE SUSPENDED SOLIDS IN THE WATER.1.DETI WILL ADHERE TO THE FOLLOWING CRITERIA FOR THE USE OF TURBIDITY CURTAIN:2.A TYPE I, II, OR III CURTAIN WILL BE SELECTED BASED ON THE FLOW CONDITION AT THE TIME OF THE CROSSING. IN MOST SITUATIONS, TURBIDITY CURTAINS SHOULD NOT BEINSTALLED ACROSS CHANNEL FLOWS.3.TURBIDITY CURTAINS WILL EXTEND THE ENTIRE DEPTH OF THE WATERCOURSE WHEN THE WATERCOURSE IS NOT SUBJECT TO TIDAL ACTION AND/OR SIGNIFICANT WIND ANDWAVE FORCES.4.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 THEWEIGHTED LOWER END OF THE SKIRT AND THE BOTTOM AT “MEAN” LOW WATER.5.IN TIDAL AND/OR WIND AND WAVE ACTION SITUATIONS, THE CURTAIN DEPTH WILL NOT BE LOWER THAN 10 TO12 FEET BELOW THE SURFACE.6.TURBIDITY CURTAINS WILL BE LOCATED PARALLEL TO THE DIRECTION OF FLOW OF A MOVING WATERBODY.7.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 OFTHUMB.8.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 ORPILES.9.WHEN THERE IS SPECIFIC NEED TO EXTEND THE CURTAIN TO THE BOTTOM OF THE WATERCOURSE IN TIDAL OR MOVING WATER CONDITIONS, A HEAVY WOVEN PERVIOUSFILTER FABRIC MAY BE SUBSTITUTED FOR THE NORMALLY RECOMMENDED IMPERVIOUS GEOTEXTILE.10.BARRIERS WILL BE OF BRIGHT COLORS TO ATTRACT THE ATTENTION OF NEARBY BOATERS.11.SEAMS IN THE FABRIC WILL BE EITHER VULCANIZED WELDED OR SEWN AND WILL DEVELOP THE FULL STRENGTH OF THE FABRIC.12.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 THEFABRIC.13.EXTERNAL ANCHORS MAY CONSIST OF WOODEN OR METAL STAKES FOR TYPE I CURTAINS; TYPE-II AND III SHOULD USE BOTTOM ANCHORS.14.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 MINIMIZETURBIDITY. SEDIMENT MAY BE REMOVED AND THE ORIGINAL DEPTH RESTORED. ANY SPOILS WILL BE TAKEN TO AN UPLAND AREA AND STABILIZED.SPOIL EXCAVATED FROM THE TRENCH WILL BE PLACED ON THE BANK ABOVE THE HIGH WATER MARK (AT LEAST 10 FEET FROM THE EDGE OF THE WATER) OR PLACED ADJACENT TOTHE TRENCH IN THE STREAM (MAJOR WATERBODIES ONLY, IN ACCORDANCE WITH THE FERC PROCEDURES) FOR USE AS BACKFILL. A PREFABRICATED SEGMENT OF PIPELINE WILLTHEN BE PLACED INTO THE TRENCH USING SIDE-BOOM TRACTORS. CONCRETE COATING (INSTALLED IN UPLANDS IN PROJECT WORKSPACE) OR PIPELINE WEIGHTS WILL BEUTILIZED, AS NECESSARY, TO PROVIDE NEGATIVE BUOYANCY FOR THE PIPELINE. ONCE THE TRENCH IS BACKFILLED, THE BANKS WILL BE RESTORED AS NEAR AS PRACTICABLE TOPRE-CONSTRUCTION CONTOURS AND STABILIZED AS DESCRIBED ABOVE.THROUGHOUT THE CONSTRUCTION PROCESS, DETI WILL FOLLOW THE FERC PROCEDURES TO AVOID OR MINIMIZE IMPACTS ON WATER QUALITY. CONSTRUCTION ACTIVITIES WILLBE SCHEDULED SO THAT THE TRENCH IS NOT EXCAVATED ACROSS THE WATERBODY UNTIL IMMEDIATELY PRIOR TO PIPE LAYING ACTIVITIES. THE DURATION OF IN-STREAMCONSTRUCTION ACTIVITIES (EXCLUDING BLASTING, IF REQUIRED) WILL BE LIMITED TO 24-HOURS ACROSS MINOR WATERBODIES (THOSE 10 FEET IN WIDTH OR LESS) AND 48 HOURSACROSS INTERMEDIATE WATERBODIES (THOSE BETWEEN 10 AND 100 FEET IN WIDTH). SITE-SPECIFIC CROSSING DRAWINGS HAVE BEEN DEVELOPED FOR MAJOR WATERBODYCROSSINGS.FLUME CROSSINGTHE FLUME CROSSING METHOD UTILIZES A FLUME PIPE(S) TO TRANSPORT STREAM FLOW ACROSS THE DISTURBED AREA AND ALLOWS TRENCHING TO BE DONE INDRIER CONDITIONS. THE FLUME PIPE(S) INSTALLED ACROSS THE TRENCH WILL BE SIZED TO ACCOMMODATE ANTICIPATED STREAM FLOWS. FLUMES AREGENERALLY NOT RECOMMENDED FOR USE ON A WATERBODY WITH A BROAD UNCONFINED CHANNEL, UNSTABLE BANKS, A PERMEABLE SUBSTRATE, EXCESSIVESTREAM FLOW, OR WHERE THE INSTALLATION AND CONSTRUCTION OF THE FLUME CROSSING WILL ADVERSELY AFFECT THE BED OR BANKS OF THE STREAM.DETI IS REQUESTING A REVIEW OF A CASE BY CASE BASIS WITH THE DEQ FOR THE ABILITY TO UTILIZE THE DRY-DITCH STREAM CROSSING METHOD (FLUMECROSSING) FOR STREAMS THAT EXCEED THE 10 FEET WIDTH. UNDER CERTAIN FIELD CONDITIONS, FLUME CROSSING PROCEDURES ARE PREFERRED OVER DAMAND PUMP METHODS. THE FOLLOWING SCENARIOS TYPICALLY ENCOUNTERED DURING CONSTRUCTION MAKE THE FLUME METHOD A BETTER OPTION ANDREDUCE THE OVERALL POTENTIAL ENVIRONMENTAL IMPACT TO THE STREAM ITSELF: STREAMS WITH HIGH FLOW RATES, AND TERRAIN CONSTRAINTS.STREAMS WITH HIGHER FLOW RATES REQUIRE MORE AND LARGER PUMPS IN ORDER TO MAINTAIN ADEQUATE UPSTREAM TO DOWNSTREAM FLOW DURINGCONSTRUCTION. DUE TO LIMITATIONS PLACED ON PIPELINE CONSTRUCTION “LIMITS OF DISTURBANCE” VIA FERC REQUIREMENTS, MANY TIMES THERE IS NOTADEQUATE SPACE IN ORDER TO INSTALL MULTIPLE PUMPS AND BACKUP PUMPS IN CASE OF A POTENTIAL PRIMARY PUMP FAILURE. ADDITIONALLY, WHEN PUMPSARE UTILIZED, CREWS ARE REQUIRED TO MAINTAIN (FUEL, MONITOR) DAY AND NIGHT. BY INSTALLING A FLUME, THE CONSTRUCTION CREW IS ABLE TO MAINTAINADEQUATE FLOW RATES OF THE STREAM WHILE CONDUCTING THE CROSSING AND ELIMINATE THE NEED TO REFUEL AND MAINTAIN PUMPS OVERNIGHT.TERRAIN CAN BE A FACTOR ESPECIALLY WHEN THE AREA LEADING INTO AND GOING AWAY FROM THE STREAM CHANNEL IS STEEP. DEPENDING ON THE OVERALLGRADE OF THE SLOPE, INSTALLING PUMPS ON SLOPED TERRAIN SHOULD BE AVOIDED OR MAY NOT BE FEASIBLE. DURING THESE SITUATIONS, THE FLUMECROSSING METHOD IS PREFERRED. A FLUME CROSSING TYPICAL IS PROVIDED.THE FLUME WATERBODY CROSSING WILL BE INSTALLED AS FOLLOWS:1.INSTALL FLUME PIPE(S) AFTER BLASTING AND OTHER ROCK BREAKING MEASURES (IF REQUIRED), BUT BEFORE TRENCHING. THE FLUME PIPE CROSSINGWILL BE MADE OPERATIONAL PRIOR TO THE START OF CONSTRUCTION IN THE STREAM.2.PROPERLY ALIGN FLUME PIPE(S) TO PREVENT BANK EROSION AND STREAMBED SCOUR.3.A LARGE FLUME PIPE (OR CULVERT) OF AN ADEQUATE SIZE TO SUPPORT NORMAL WATER CHANNEL FLOW WILL THEN BE INSTALLED IN THE STREAM BEDACROSS THE PROPOSED PIPELINE TRENCH CENTERLINE.4.SAND BAGS, COARSE AGGREGATE (MINIMUM SIZE), OR RIPRAP WILL BE PLACED CLOSE TO EACH END OF THE FLUME PIPE SO AS TO DAM OFF THE CREEKFORCING THE WATER TO FLOW THROUGH THE FLUME PIPE (SOME MODIFICATIONS TO THE STREAM BOTTOM MAY BE REQUIRED TO ACHIEVE AN EFFECTIVESEAL).5.THE ENTRAPPED WATER CAN THEN BE PUMPED FROM THE CREEK WITHIN THE DAMMED-OFF AREA AND IN THE PROPOSED TRENCH CENTERLINE INTO ADEWATERING STRUCTURE. THE TRENCH CAN THEN BE DUG UNDER THE FLUME PIPE. THE PIPE SECTIONS WILL THEN BE INSTALLED TO THE PROPER DEPTHUNDER THE FLUME PIPE. AFTER PIPE SECTIONS ARE INSTALLED, THE DITCH WILL BE BACKFILLED AND RE-STABILIZATION WILL THEN BE CARRIED OUT.6.THE FLUME PIPE WILL NOT BE REMOVED DURING TRENCHING, PIPE LAYING (THREAD PIPE UNDERNEATH THE FLUME PIPE. 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 WILLINSTALL A PERMANENT SLOPE BREAKER ACROSS THE CONSTRUCTION ROW AT THE BASE OF SLOPES GREATER THAN 5 PERCENT WHERE THE BASE OF THESLOPE IS LESS THAN 50 FEET FROM THE WETLAND, OR AS NEEDED TO PREVENT SEDIMENT TRANSPORT INTO THE WETLAND. IN SOME AREAS, WITH THEAPPROVAL OF THE EI, AN EARTHEN BERM MAYBE SUITABLE AS A SEDIMENT BARRIER ADJACENT TO THE WETLAND.7.THE USE OF THE FLUME PIPE CROSSING METHOD WILL LAST LESS THAN 72 HOURS. HOWEVER, DETI IS REQUESTING A REVIEW OF A CASE BY CASE BASISWITH THE DEQ IN AREAS WHERE ROCK IS ENCOUNTERED WHICH REQUIRES BLASTING/ROCK HAMMERING THAT COULD SIGNIFICANTLY INCREASE THE AMOUNTOF TIME NEEDED TO COMPLETE THE CROSSING OR FAILURE IN CROSSING METHOD REQUIRES ADDITIONAL TIME TO EITHER MITIGATE OR CHANGE.8.RESTORE PRE-CONSTRUCTION WETLAND CONTOURS TO MAINTAIN THE WETLAND HYDROLOGY.9.REVEGETATION AND PERMANENT ROW MAINTENANCE PROCEDURES AS WELL AS THE USE OF LIME, MULCH OR FERTILIZER IN WETLAND AREAS ISADDRESSED IN THE RESTORATION AND REHABILITATION PLAN PROVIDED IN APPENDIX R.10.DETI WILL NOT USE HERBICIDES OR PESTICIDES IN OR WITHIN 100 FEET OF A WETLAND, EXCEPT AS ALLOWED BY THE APPROPRIATE FEDERAL OR STATEAGENCY.11.REMOVE PROJECT-RELATED MATERIAL USED TO SUPPORT EQUIPMENT ON THE CONSTRUCTION ROW, INCLUDING TIMBER MATTING AND PREFABRICATEDEQUIPMENT MATS, UPON COMPLETION OF CONSTRUCTION.12.REMOVE TEMPORARY SEDIMENT BARRIERS LOCATED AT THE BOUNDARY BETWEEN WETLAND AND ADJACENT UPLAND AREAS AFTER UPLANDREVEGETATION AND STABILIZATION OF ADJACENT UPLAND AREAS ARE SUCCESSFUL.13.WITHIN 3 YEARS AFTER CONSTRUCTION, FILE A REPORT WITH FERC IDENTIFYING THE STATUS OF THE WETLAND REVEGETATION EFFORTS ANDDOCUMENTING SUCCESS.GENERAL NOTES AND COMMENTS:SYM.DATEBYREVISION INFORMATIONPROJECT/TASKAPP.--ISSUED FOR PERMITTINGJR03/09./20170APP.
