4h. Explain the purpose of the proposed project:*
The purpose of the Piedmont Natural Gas (PNG) Rocky River HDD project is to install approximately 3,125 feet of 30-inch pipeline to replace a section of existing pipe beneath Rocky
River due to integrity and corrosion concerns.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
The proposed Project includes the replacement of approximately 3,125 linear feet of 30-inch pipe adjacent to an existing PNG right of way (ROW) (Attachment A: Figure A-3).
Approximately 725 feet of pipeline would be constructed and installed via open -cut method from the existing ROW to the Horizontal Directional Drill (HDD) entry and exit points and
approximately 2,400
feet of pipeline will be installed via HDD method beneath Rocky River. The new pipeline will be approximately 52 feet below ground where it crosses the Rocky River. The portions of
pipeline that will be installed via the open -cut method are in an existing active agriculture field on the west side of the Rocky River and in an existing maintained ROW of the east side of
the Rocky
River.
Additional Project components include an approximately 1,800-foot-long temporary pipestring laydown area, an approximately 16-acre temporary laydown area, and 4,875 feet of extant
access roads. Gravel may be added to the existing access roads, however, no subsurface impacts are anticipated from use of the access roads or temporary laydown areas.
Subsurface disturbance will be limited to the open cut sections, the HDD entry and exit points, and the two temporary retention ponds west of Rocky River. Tree clearing is proposed for
a 20-foot-wide-permanant easement over the HDD installed portion of the pipeline, approximately 0.3 acres for the pipe -string laydown, and approximately 2 acres for the HDD drill pad
and tie-in east of the Rocky River.
Construction and operation of the Project will result in the permanent conversion of approximately 0.051-acres of PFO wetlands to PEM wetlands. There will be no net loss of wetlands
as a result of the Project. There will be no impacts to streams as a result of the Project.
PNG plans to begin construction in December 2020; and the anticipated in-service date is March 2021.
4j. Please upload project drawings for the proposed project.

la. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
All route alternatives are considered and designed to reduce environmental impacts and keep land disturbance to a minimum. Reducing impacts to
wetlands and vaterbodies was considered during route analysis for the Rocky River Project. Alternate pipeline routes, temporary workspaces, and
access roads would either conflict with epsting pipelines, landowner requests or cause increased environmental impacts. The direction and location of
the proposed pipeline, direction and location of an epsting pipeline, and and temporary workspaces required for an HDD drill pad location within
Project area does not enable a route for complete avoidance of forest wetland. However, temporary conversion impacts have been limited to 0.05
acres There are no other viable alternatives to the Proposed Project area that would completely avoid impacts to wetlands. The Project has been
reduced in size to the extent possible so the purpose of the Project can be practically accomplished while minimizing land disturbance, preserving
natural resources, and protecting water quality to the extent possible.
For the Rocky River and another unnamed intermittent stream crossing, the pipeline will be installed using HDD, which means the permanent pipeline
easement will not require earth work. Tree clearing will be required as part of PNG's Integrity Management Plan.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
For the Rocky River and additional intermittent stream crossing, the pipeline will be installed using HDD, which means the permanent pipeline
easement will not require earth work. Tree clearing will be required as part of PNG's Integrity Management Plan.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
F Yes f• No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Impacts to the wetland within the Project will be temporary and there will be no permanent conversion or loss of wetlands.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
1. Diffuse Flow Plan

PERFORMANCE OF THE EROSION CONTROL STRUCTURE AND REPAIR OR
REPLACE THOSE STRUCTURES, AS NECESSARY.
6. ALL STORM DRAIN INLETS SHALL BE PROTECTED BY APPROPRIATE BMPS
DURING CONSTRUCTION, UNTIL ALL SOURCES WITH POTENTIAL FOR
DISCHARGE TO THE INLETS HAVE BEEN STABILIZED.
7. ALL EXISTING DRAIN INLETS SHALL HAVE INLET PROTECTION INSTALLED IN
ACCORDANCE WITH NORTH CAROLINA MANUAL FOR EROSION CONTROL.
EROSION PROTECTION MAY BE REMOVED WHEN VEGETATION IS
ESTABLISHED.
8. IN ACCORDANCE WITH SECTION II.B.2 OF THE NPDES GENERAL PERMIT, ANY
DISTURBED AREA LEFT EXPOSED SHALL BE STABILIZED WITH TEMPORARY
SEEDING WITHIN 7 TO 14 DAYS IN ACCORDANCE WITH NORTH CAROLINA
EROSION AND SEDIMENT CONTROL PLANNING AND DESIGN MANUAL SECTION
6.11. PERMANENT STABILIZATION SHALL BE ACHIEVED THROUGH PERMANENT
SEEDING FOR ALL DISTURBED AREAS. SEE SEEDING SCHEDULE IN NORTH

TEMPORARY SEEDING NOTES:
1. COMPLETE GRADING BEFORE PREPARING SEEDBEDS, AND INSTALL ALL NECESSARY EROSION
CONTROL PRACTICES SUCH AS, DIKES, WATERWAYS, AND BASINS. MINIMIZE STEEP SLOPES BECAUSE
THEY MAKE SEEDBED PREPARATION DIFFICULT AND INCREASE THE EROSION HAZARD. IF SOILS
BECOME COMPACTED DURING GRADING, LOOSEN THEM TO A DEPTH OF 6-8 INCHES USING A RIPPER,
HARROW, OR CHISEL PLOW.
SEEDBED PREPARATION
2. GOOD SEEDBED PREPARATION IS ESSENTIAL TO SUCCESSFUL PLANT ESTABLISHMENT. A GOOD
SEEDBED IS WELL -PULVERIZED, LOOSE, AND UNIFORM. WHERE HYDROSEEDING METHODS ARE USED,
THE SURFACE MAY BE LEFT WITH A MORE IRREGULAR SURFACE OF LARGE CLODS AND STONES.
3. LIMING —APPLY LIME ACCORDING TO SOIL TEST RECOMMENDATIONS. IF THE PH (ACIDITY) OF THE
SOIL IS NOT KNOWN, AN APPLICATION OF GROUND AGRICULTURAL LIMESTONE AT THE RATE OF 1 TO 1
1/2 TONS/ACRE ON COARSE -TEXTURED SOILS AND 2-3 TONS/ACRE ON FINE -TEXTURED SOILS IS
USUALLY SUFFICIENT. APPLY LIMESTONE UNIFORMLY AND INCORPORATE INTO THE TOP 4-6 INCHES
OF SOIL. SOILS WITH A PH OF 6 OR HIGHER NEED NOT BE LIMED.
4. FERTILIZER —BASE APPLICATION RATES ON SOIL TESTS. WHEN THESE ARE NOT POSSIBLE, APPLY
A 10-10-10 GRADE FERTILIZER AT 700-1,000 LB/ACRE. BOTH FERTILIZER AND LIME SHOULD BE
INCORPORATED INTO THE TOP 4-6 INCHES OF SOIL. IF A HYDRAULIC SEEDER IS USED, DO NOT MIX
SEED AND FERTILIZER MORE THAN 30 MINUTES BEFORE APPLICATION.
5. SURFACE ROUGHENING —IF RECENT TILLAGE OPERATIONS HAVE RESULTED IN A LOOSE
SURFACE, ADDITIONAL ROUGHENING MAY NOT BE REQUIRED, EXCEPT TO BREAK UP LARGE CLODS. IF
RAINFALL CAUSES THE SURFACE TO BECOME SEALED OR CRUSTED, LOOSEN IT JUST PRIOR TO
SEEDING BY DISKING, RAKING, HARROWING, OR OTHER SUITABLE METHODS. GROOVE OR FURROW
SLOPES STEEPER THAN 3:1 ON THE CONTOUR BEFORE SEEDING (PRACTICE 6.03, SURFACE
ROUGHENING).
PLANT SELECTION
6. SELECT AN APPROPRIATE SPECIES OR SPECIES MIXTURE FROM TABLE 6.10A FOR SEEDING IN LATE
WINTER AND EARLY SPRING, TABLE 6.10B FOR SUMMER, AND TABLE 6.10C FOR FALL.
7. IN THE MOUNTAINS, DECEMBER AND JANUARY SEEDINGS HAVE POOR CHANCES OF SUCCESS. WHEN
IT IS NECESSARY TO PLANT AT THESE TIMES, USE RECOMMENDATIONS FOR FALL AND A SECURELY
TACKED MULCH.
SEEDING
8. EVENLY APPLY SEED USING A CYCLONE SEEDER (BROADCAST), DRILL, CULTIPACKER SEEDER, OR
HYDROSEEDER. USE SEEDING RATES GIVEN IN TABLES 6.10A-6.10C. BROADCAST SEEDING AND
HYDROSEEDING ARE APPROPRIATE FOR STEEP SLOPES WHERE EQUIPMENT CANNOT BE DRIVEN.
HAND BROADCASTING IS NOT RECOMMENDED BECAUSE OF THE DIFFICULTY IN ACHIEVING A UNIFORM
DISTRIBUTION.
9. SMALL GRAINS SHOULD BE PLANTED NO MORE THAN 1 INCH DEEP, AND GRASSES AND LEGUMES NO
MORE THAN 1/2 INCH. BROADCAST SEED MUST BE COVERED BY RAKING OR CHAIN DRAGGING, AND
THEN LIGHTLY FIRMED WITH A ROLLER OR CULTIPACKER. HYDROSEEDED MIXTURES SHOULD
INCLUDE A WOOD FIBER (CELLULOSE) MULCH.
MULCHING
10. THE USE OF AN APPROPRIATE MULCH WILL HELP ENSURE ESTABLISHMENT UNDER NORMAL
CONDITIONS, AND IS ESSENTIAL TO SEEDING SUCCESS UNDER HARSH SITE CONDITIONS (PRACTICE
6.14, MULCHING). HARSH SITE CONDITIONS INCLUDE:
• SEEDING IN FALL FOR WINTER COVER (WOOD FIBER MULCHES ARE NOT CONSIDERED ADEQUATE FOR THIS
USE),
• SLOPES STEEPER THAN 3:1,
• EXCESSIVELY HOT OR DRY WEATHER,
• ADVERSE SOILS (SHALLOW, ROCKY, OR HIGH IN CLAY OR SAND), AND
• AREAS RECEIVING CONCENTRATED FLOW.
11. IF THE AREA TO BE MULCHED IS SUBJECT TO CONCENTRATED WATER FLOW, AS IN CHANNELS,
ANCHOR MULCH WITH NETTING (PRACTICE 6.14, MULCHING).
TEMPORARY SEEDING MAINTENANCE NOTES:
1. RESEED AND MULCH AREAS WHERE SEEDLING EMERGENCE IS POOR, OR WHERE EROSION OCCURS,
AS SOON AS POSSIBLE. DO NOT MOW. PROTECT FROM TRAFFIC AS MUCH AS POSSIBLE.

SOIL PREPARATION
1. PROPER SOIL PREPARATION IS NECESSARY FOR SUCCESSFUL SEED GERMINATION AND ROOT ESTABLISHMENT. IT IS
ALSO NECESSARY FOR ESTABLISHMENT OF ROOTED SPRIGS, SOD AND WOODY PLANTS. HEAVILY COMPACTED SOILS
PREVENT AIR, NUTRIENTS AND MOISTURE FROM REACHING ROOTS THEREBY RETARDING OR PREVENTING PLANT
GROWTH. THE SUCCESS OF SITE STABILIZATION AND REDUCTION OF FUTURE MAINTENANCE ARE DEPENDENT ON AN
ADEQUATELY PREPARED SOIL BED. FOLLOWING ARE THE REQUIREMENTS FOR PREPARATION OF AREAS TO BE
VEGETATED BY GRASSING, SPRIGGING, SODDING, AND/OR PLANTING OF WOODY PLANTS:
GENERAL REQUIREMENTS:
2. PREPARATION FOR PRIMARY/PERMANENT STABILIZATION SHALL NOT BEGIN UNTIL ALL CONSTRUCTION AND UTILITY
WORK WITHIN THE PREPARATION AREA IS COMPLETE. HOWEVER, IT MAY BE NECESSARY TO PREPARE FOR NURSE
CROPS PRIOR TO COMPLETION OF CONSTRUCTION AND INSTALLATION OF UTILITIES.
3. A NORTH CAROLINA DEPARTMENT OF AGRICULTURE SOILS TEST (OR EQUAL) SHALL BE OBTAINED FOR ALL AREAS TO BE
SEEDED, SPRIGGED, SODDED OR PLANTED. RECOMMENDED FERTILIZER AND PH ADJUSTING PRODUCTS SHALL BE
INCORPORATED INTO THE PREPARED AREAS AND BACKFILL MATERIAL PER THE TEST.
4. ALL AREAS TO BE SEEDED OR PLANTED SHALL BE TILLED OR RIPPED TO A DEPTH SPECIFIED ON THE APPROVED PLANS,
CONSTRUCTION SEQUENCE AND/OR CONSTRUCTION BID LIST. RIPPING CONSISTS OF CREATING FISSURES IN A
CRISS-CROSS PATTERN OVER THE ENTIRE SURFACE AREA, UTILIZING AN IMPLEMENT THAT WILL NOT GLAZE THE SIDE
WALLS OF THE FISSURES. SITE PREPARATION THAT DOES NOT COMPLY WITH THESE DOCUMENTS SHALL NOT BE
ACCEPTABLE. THE DEPTH OF SOIL PREPARATION MAY BE ESTABLISHED AS A RANGE BASED ON THE APPROVAL OF THE
REVIEWING STATE OR LOCAL AGENCY. ONCE TILLED OR RIPPED ACCORDING TO THE APPROVED PLAN, ALL AREAS ARE
TO BE RETURNED TO THE APPROVED FINAL GRADE. PH MODIFIERS AND/OR OTHER SOIL AMENDMENTS SPECIFIED IN
THE SOIL TESTS CAN BE ADDED DURING THE SOIL PREPARATION PROCEDURE OR AS DESCRIBED BELOW.
5. ALL STONES LARGER THAN THREE (3) INCHES ON ANY SIDE, STICKS, ROOTS, AND OTHER EXTRANEOUS MATERIALS THAT
SURFACE DURING THE BED PREPARATION SHALL BE REMOVED.
AREAS TO BE SEEDED:
6. TILL OR DISC THE PREPARED AREAS TO BE SEEDED TO A MINIMUM DEPTH OF FOUR (4) INCHES. REMOVE STONES
LARGER THAN THREE (3) INCHES ON ANY SIDE, STICKS, ROOTS AND OTHER EXTRANEOUS MATERIALS THAT SURFACE. IF
NOT INCORPORATED DURING THE SOIL PREPARATION PROCESS, ADD PH MODIFIER AND FERTILIZERS AT THE RATE
SPECIFIED IN THE SOIL TEST REPORT.
7. RE -COMPACT THE AREA UTILIZING A CULTIPACKER ROLLER. THE FINISHED GRADE SHALL BE A SMOOTH EVEN SOIL
SURFACE WITH A LOOSE, UNIFORMLY FINE TEXTURE. ALL RIDGES AND DEPRESSIONS SHALL BE REMOVED AND FILLED
TO PROVIDE THE APPROVED SURFACE DRAINAGE. SEEDING OF GRADED AREAS IS TO BE DONE IMMEDIATELY AFTER
FINISHED GRADES ARE OBTAINED AND SEEDBED PREPARATION IS COMPLETED.
AREAS TO BE SPRIGGED, SODDED, AND/OR PLANTED:
8. AT THE TIME OF PLANTING TILL OR DISC THE PREPARED AREAS TO A DEPTH OF FOUR (4) TO SIX (6) INCHES BELOW THE
APPROVED FNISHED GRADE. REMOVE ALL STONES LARGER THAN THREE (3) INCHES ON ANY SIDE, STICKS, ROOTS AND
OTHER EXTRANEOUS MATERIALS THAT SURFACE. IF NOT INCORPORATED IN THE RIPPING PROCESS, ADD PH MODIFIER,
FERTILIZER, AND OTHER RECOMMENDED SOIL AMENDMENTS.
9. RE -COMPACT THE AREA UTILIZING A CULTIPACKER ROLLER AND PREPARE FNAL GRADES AS DESCRIBED ABOVE.
INSTALL SPRIGS, SOD AND PLANTS AS DIRECTED IMMEDIATELY AFTER FINE GRADING IS COMPLETE. MULCH, MAT
AND/OR TACK AS SPECIFIED.

APPROXIMATELY 1-3/8" WIDE MEASURED PARALLEL TO THE FENCE, AND
HAVE A MINIMUM WEIGHT OF 1.25 LB/LINEAR FT. THE POSTS MUST BE
EQUIPPED WITH AN ANCHOR PLATE HAVING A MINIMUM AREA OF 14.0
SQUARE INCHES AND BE OF THE SELF -FASTENER ANGLE STEEL TYPE TO
HAVE A MEANS OF RETAINING WIRE AND COIR FIBER MAT IN THE DESIRED
POSITION WITHOUT DISPLACEMENT.
4. USE 9-GAUGE HIGH TENSION WIRE FOR SUPPORT WIRE.
5. GRADE THE BASIN SO THAT THE BOTTOM IS LEVEL FRONT TO BACK AND
SIDE TO SIDE.
6. INSTALL THE COIR FIBER BAFFLES IMMEDIATELY UPON EXCAVATION OF
THE BASINS.
7. INSTALL POSTS ACROSS THE WIDTH OF THE SEDIMENT TRAP (PRACTICE
6.62, SEDIMENT FENCE).
8. STEEL POSTS SHOULD BE DRIVEN TO A DEPTH OF 24 INCHES AND SPACED
A MAXIMUM OF 4 FEET APART. THE TOP OF THE FABRIC SHOULD BE A
MINIMUM OF 6 INCHES HIGHER THAN THE INVERT OF THE SPILLWAY. TOPS
OF BAFFLES SHOULD BE A MINIMUM OF 2 INCHES LOWER THAN THE TOP
OF THE EARTHEN EMBANKMENT.
9. INSTALL AT LEAST THREE ROWS OF BAFFLES BETWEEN THE INLET AND
OUTLET DISCHARGE POINT. BASINS LESS THAN 20 FEET IN LENGTH MAY
USE 2 BAFFLES.
10. ATTACH A 9 GAUGE HIGH TENSION WIRE STRAND TO THE STEEL POSTS AT
A HEIGHT OF 6 INCHES ABOVE THE SPILLWAY ELEVATION WITH PLASTIC
TIES OR WIRE FASTENERS TO PREVENT SAGGING. IF THE TEMPORARY
SEDIMENT BASIN WILL BE CONVERTED TO A PERMANENT STORMWATER
BASIN OF A GREATER DEPTH, THE BAFFLE HEIGHT SHOULD BE BASED ON
THE POOL DEPTH DURING USE AS A TEMPORARY SEDIMENT BASIN.
11. EXTEND 9 GAUGE MINIMUM HIGH TENSION WIRE STRAND TO SIDE OF
BASIN OR INSTALL STEEL T-POSTS TO ANCHOR BAFFLE TO SIDE OF BASIN
AND SECURE TO VERTICAL END POSTS AS SHOWN IN FIGURE 6.65B.
12. DRAPE THE COIR FIBER MAT OVER THE WIRE STRAND MOUNTED AT A
HEIGHT OF 6 INCHES ABOVE THE SPILLWAY ELEVATION. SECURE THE
COIR FIBER MAT TO THE WIRE STRAND WITH PLASTIC TIES OR WIRE
FASTENERS. ANCHOR THE MATTING TO THE SIDES AND FLOOR OF THE
BASIN WITH 12 INCH WIRE STAPLES, APPROXIMATELY 1 FT APART, ALONG
THE BOTTOM AND SIDE SLOPES OF THE BASIN.
13. DO NOT SPLICE THE FABRIC, BUT USE A CONTINUOUS PIECE ACROSS THE
BASIN
14. ADJUSTMENTS MAY BE REQUIRED IN THE STAPLING REQUIREMENTS TO
FIT INDIVIDUAL SITE CONDITIONS.
POROUS BAFFLE MAINTENANCE NOTES:
1. INSPECT BAFFLES AT LEAST ONCE A WEEK AND AFTER EACH RAINFALL.
MAKE ANY REQUIRED REPAIRS IMMEDIATELY.
2. BE SURE TO MAINTAIN ACCESS TO THE BAFFLES. SHOULD THE FABRIC OF
A BAFFLE COLLAPSE, TEAR, DECOMPOSE, OR BECOME INEFFECTIVE,
REPLACE IT PROMPTLY.
3. REMOVE SEDIMENT DEPOSITS WHEN IT REACHES HALF FULL, TO PROVIDE
ADEQUATE STORAGE VOLUME FOR THE NEXT RAIN AND TO REDUCE
PRESSURE ON THE BAFFLES. TAKE CARE TO AVOID DAMAGING THE
BAFFLES DURING CLEANOUT, AND REPLACE IF DAMAGED DURING
CLEANOUT OPERATIONS. SEDIMENT DEPTH SHOULD NEVER EXCEED HALF
THE DESIGNED STORAGE DEPTH.
4. AFTER THE CONTRIBUTING DRAINAGE AREA HAS BEEN PROPERLY
STABILIZED, REMOVE ALL BAFFLE MATERIALS AND UNSTABLE SEDIMENT
DEPOSITS, BRING THE AREA TO GRADE, AND STABILIZE IT.

SKIMMER SEDIMENT BASIN
SKIMMER SEDIMENT BASIN CONSTRUCTION NOTES:
1. Clear, grub, and strip the area under the embankment of all vegetation and
root mat. Remove all surface soil containing high amounts of organic matter
and stockpile or dispose of it properly. Haul all objectionable material to the
designated disposal area. Place temporary sediment control measures below
basin as needed
2. Ensure that fill material for the embankment is free of roots, woody
vegetation, organic matter, and other objectionable material. Place the fill in
lifts not to exceed 9 inches, and machine compact it. Over fill the embankment
6 inches to allow for settlement.
3. Shape the basin to the specified dimensions. Prevent the skimming device
from settling into the mud by excavating a shallow pit under the skimmer or
providing a low support under the skimmer of stone or timber.
4. Place the barrel (typically 4-inch Schedule 40 PVC pipe) on a firm, smooth
foundation of impervious soil. Do not use pervious material such as sand,
gravel, or crushed stone as backfill around the pipe. Place the fill material
around the pipe spillway in 4-inch layers and compact it under and around
the pipe to at least the same density as the adjacent embankment. Care must
be taken not to raise the pipe from the firm contact with its foundation when
compacting under the pipe haunches.
Place a minimum depth of 2 feet of compacted backfill over the pipe spillway
before crossing it with construction equipment. In no case should the pipe
conduit be installed by cutting a trench through the dam after the embankment
is complete.
5. Assemble the skimmer following the manufacturers instructions, or as
designed.
6. Lay the assembled skimmer on the bottom of the basin with the flexible
joint at the inlet of the barrel pipe. Attach the flexible joint to the barrel pipe
and position the skimmer over the excavated pit or support. Be sure to attach
a rope to the skimmer and anchor it to the side of the basin. This will be used
to pull the skimmer to the side for maintenance.
7. Earthen spillways -Install the spillway in undisturbed soil to the greatest
extent possible. The achievement of planned elevations, grade, design width,
and entrance and exit channel slopes are critical to the successful operation
of the spillway. The spillway should be lined with laminated plastic or
impermeable geotextile fabric. The fabric must be wide and long enough to
cover the bottom and sides and extend onto the top of the dam for anchoring
in a trench. The edges may be secured with 8-inch staples or pins. The fabric
must be long enough to extend down the slope and exit onto stable ground.
The width of the fabric must be one piece, not joined or spliced; otherwise
water can get under the fabric. If the length of the fabric is insufficient for the
entire length of the spillway, multiple sections, spanning the complete width,
may be used. The upper section(s) should overlap the lower section(s) so
that water cannot flow under the fabric. Secure the upper edge and sides
of the fabric in a trench with staples or pins. (Adapted from "A Manual for
Designing, Installing and Maintaining Skimmer Sediment Basins." February,
1999. J. W. Faircloth & Son.).
8. Inlets -Discharge water into the basin in a manner to prevent erosion. Use
temporary slope drains or diversions with outlet protection to divert sediment -
laden water to the upper end of the pool area to improve basin trap efficiency
(References: Runoff Control Measures and Outlet Protection).
9. Erosion control -Construct the structure so that the disturbed area is
minimized. Divert surface water away from bare areas. Complete the
embankment before the area is cleared. Stabilize the emergency spillway
embankment and all other disturbed areas above the crest of the principal
spillway immediately after construction (References: Surface Stabilization).
10. Install porous baffles as specified in Practice 6.65, Porous Baffles.
11. After all the sediment -producing areas have been permanently stabilized,
remove the structure and all the unstable sediment. Smooth the area to
blend with the adjoining areas and stabilize properly (References: Surface
Stabilization).
SKIMMER SEDIMENT BASIN MAINTENANCE NOTES:
Inspect skimmer sediment basins at least weekly and after each significant
(one-half inch or greater) rainfall event and repair immediately. Remove
sediment and restore the basin to its original dimensions when sediment
accumulates to one-half the height of the first baffle. Pull the skimmer to
one side so that the sediment underneath it can be excavated. Excavate the
sediment from the entire basin, not just around the skimmer or the first cell.
Make sure vegetation growing in the bottom of the basin does not hold down
the skimmer.
Repair the baffles if they are damaged. Re -anchor the baffles if water is
flowing underneath or around them.
If the skimmer is clogged with trash and there is water in the basin, usually
jerking on the rope will make the skimmer bob up and down and dislodge
the debris and restore flow. If this does not work, pull the skimmer over to
the side of the basin and remove the debris. Also check the orifice inside the
skimmer to see if it is clogged; if so remove the debris.
If the skimmer arm or barrel pipe is clogged, the orifice can be removed and
the obstruction cleared with a plumber's snake or by flushing with water. Be
sure and replace the orifice before repositioning the skimmer.
Check the fabric lined spillway for damage and make any required repairs
with fabric that spans the full width of the spillway. Check the embankment,
spillways, and outlet for erosion damage, and inspect the embankment for
piping and settlement. Make all necessary repairs immediately. Remove all
trash and other debris from the skimmer and pool areas.
Freezing weather can result in ice forming in the basin. Some special
precautions should be taken in the winter to prevent the skimmer from
plugging with ice.

Do you know the name of the staff member you would like to request a meeting with?
Please give a brief project description below.*

The proposed Project includes the replacement of approximately 3,125
linear feet of 30-inch pipe adjacent to an existing Piedmont Natural Gas
right of way (ROW). Approximately 725 feet of pipeline would be
constructed and installed via open -cut method from the existing ROW to
the Horizontal Directional Drill (HDD) entry and exit points and
approximately 2,400 feet of pipeline will be installed via HDD method
beneath Rocky River. The new pipeline will be approximately 52 feet below
ground where it crosses the Rocky River. The portions of pipeline that will
be installed via the open -cut method are in an existing active agriculture
field on the west side of the Rocky River and in an existing maintained
ROW of the east side of the Rocky River. Additional Project components
include an approximately 1,800-foot-long temporary pipe string area, an
approximately 16-acre temporary area, and 4,875 feet of extant access
roads.
Please give a couple of dates you are available for a meeting.
