Do you know the name of the staff member you would like to request a meeting with?
No
Please give a brief project description below.

PNG proposes to retrofit Line 2 to be efficiently assessed through In -
Line Inspection (ILI). ILI assessment of transmission pipeline assets is
part of Piedmont Natural Gas's Transmission Integrity Management
Program standards and practices.
PNG determined that an existing fitting was impacting their ability to
perform ILI tool inspections for the pipeline specifically at the Line 2
Segment 2 Issue 3 site. The project will consist of removing the wall
thickness transition piece and replacing it with a new one that
conforms with current PNG standards. An outage of the pipeline to
perform the work will not be feasible due to the current gas flow
demands. Therefore, a stopple system with a bypass will be installed
around the faulty fitting to allow for continued gas flow during
replacement. Stopple fittings will be installed on the pipeline
approximately 10-feet in either direction. Access to the site will
require temporary driveways, a turnaround, and matting which will
result in unavoidable impacts to a jurisdictional wetland features.
According to General Water Quality Certification No. 4133, these
activities not require written authorization or approval from the
NCDWR. This is a for the record only submittal to comply with the
electronic Pre -Construction Notification Required for the USACE 404
Nationwide 12 authorization.
Please give a couple of dates you are available for a meeting.

GENERAL SEEDING REQUIREMENTS FOR UPLAND AREAS
GENERAL SEEDING REQUIREMENTS FOR WETLAND AREAS
SEEDBED REQUIREMENTS:
ESTABLISHMENT OF VEGETATION SHOULD NOT BE ATTEMPTED ON
SITES THAT ARE UNSUITABLE DUE TO EXCESSIVE SOIL COMPACTION,
INAPPROPRIATE SOIL TEXTURE, POOR DRAINAGE, CONCENTRATED
OVERLAND FLOW, OR STEEPNESS OF SLOPE UNTIL MEASURES HAVE
BEEN TAKEN TO CORRECT THESE PROBLEMS.
TO MAINTAIN A GOOD STAND OF VEGETATION, THE SOIL MUST MEET
CERTAIN MINIMUM REQUIREMENTS AS A GROWTH MEDIUM. THE
EXISTING SOIL SHOULD HAVE THESE CRITERIA:
·ENOUGH FINE-GRAINED (SILT AND CLAY) MATERIAL TO
MAINTAIN ADEQUATE MOISTURE AND NUTRIENT SUPPLY
(AVAILABLE WATER CAPACITY OF AT LEAST .05 -INCHES OF
WATER TO 1-INCH OF SOIL.
·SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION.
·SUFFICIENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT
ZONE. THE DEPTH TO ROCK OR IMPERMEABLE LAYERS SUCH
AS HARDPANS SHOULD BE 12-INCHES OR MORE, EXCEPT ON
SLOPES STEEPER THAN 2:1 WHERE THE ADDITION OF SOIL IS
NOT FEASIBLE.
·A FAVORABLE PH RANGE FOR PLANT GROWTH, USUALLY 6.0 -
6.5.
·FREE FROM LARGE ROOTS, BRANCHES, STONES, LARGE CLODS
OF EARTH, OR TRASH OF ANY KIND. CLODS AND STONES MAY
BE LEFT ON SLOPES STEEPER THAN 3:1 IF THEY ARE TO BE
HYDRO SEEDED.
IF ANY OF THE ABOVE CRITERIA ARE NOT MET, IE; IF EXISTING SOIL IS
TOO COARSE, DENSE, SHALLOW OR ACIDIC TO FOSTER VEGETATION,
SPECIAL AMENDMENTS ARE REQUIRED. THE SOIL CONDITIONERS
DESCRIBED BELOW MAY BE BENEFICIAL OR, PREFERABLY, TOPSOIL
MAY BE APPLIED.
SEEDBED PREPARATION:
INSTALL NECESSARY MECHANICAL EROSION AND SEDIMENTATION CONTROL
PRACTICES BEFORE SEEDING, AND COMPLETE GRADING ACCORDING TO THE
APPROVED PLAN. LIME AND FERTILIZER NEEDS SHOULD BE DETERMINED BY
SOIL TEST, DIRECTIONS, SAMPLE CARTONS, AND INFORMATION SHEETS ARE
AVAILABLE THROUGH COUNTY AGRICULTURAL EXTENSION OFFICES. TESTING
IS ALSO DONE BY COMMERCIAL LABORATORIES.
WHEN SOIL TEST RESULTS ARE NOT AVAILABLE, FOLLOW RATES SUGGESTED IN
THE SEEDING SPECIFICATIONS TABLES.
APPLY LIME AND FERTILIZER EVENLY AND INCORPORATE INTO THE TOP
4-6-INCHES OF SOIL BY DISKING OR OTHER SUITABLE MEANS. OPERATE
MACHINERY ON THE CONTOUR. WHEN USING A HYDRO SEEDER, APPLY LIME
AND FERTILIZER TO A ROUGH, LOOSE SURFACE.
ROUGHEN SURFACES PRIOR TO SEEDING.
COMPLETE SEEDBED PREPARATION BY BREAKING UP LARGE CLODS AND
RAKING INTO A SMOOTH, UNIFORM SURFACE (SLOPES LESS THAN 3:1). FILL IN
OR LEVEL DEPRESSIONS THAT CAN COLLECT WATER. BROADCAST SEED INTO
A FRESHLY LOOSENED SEEDBED THAT HAS NOT BEEN SEALED BY RAINFALL.
SEEDING:
USE CERTIFIED SEED FOR PERMANENT SEEDING WHENEVER POSSIBLE.
LABELING OF NON-CERTIFIED SEED IS ALSO REQUIRED BY LAW. LABELS
CONTAIN IMPORTANT INFORMATION ON SEED PURITY, GERMINATION, AND
PRESENCE OF WOOD SEEDS MUST MEET STATE STANDARDS FOR CONTENT OF
NOXIOUS WEEDS. DO NOT ACCEPT SEED CONTAINING “PROHIBITED” NOXIOUS
WEED SEED.
INOCULATE LEGUME SEED WITH THE RHIZOBIUM BACTERIA APPROPRIATE TO
THE SPECIES OF LEGUME.
APPLY SEED UNIFORMLY WITH A CYCLONE SEEDER, DROP-TYPE SPREADER.
DRILL. CULTIPACKER SEEDER, OR HYDRO SEEDER ON A FIRM, FRIABLE
SEEDBED.
WHEN USING A DRILL OR CULTIPACKER SEEDER, PLANT SMALL GRAINS NO
MORE THE 1-INCH DEEP, GRASSES AND LEGUMES NO MORE THAN 1/2-INCH.
EQUIPMENT SHOULD BE CALIBRATED IN THE FIELD FOR DESIRED SEEDING
RATE.
WHEN USING BROADCAST-SEEDING METHODS, SUBDIVIDE THE AREA INTO
WORKABLE SECTIONS AND DETERMINE THE AMOUNT OF SEED NEEDED FOR
EACH SECTION. APPLY 1/2 THE SEED WHILE MOVING BACK AND FORTH
ACROSS THE AREA, MAKING A UNIFORM PATTERN; THEN APPLY THE SECOND
HALF IN THE SAME WAY, BUT MOVING AT RIGHT ANGLES TO THE FIRST PASS.
MULCH ALL PLANTING IMMEDIATELY AFTER SEEDING WHEN USING A DRILL OR
BROADCAST SPREADER.
HYDRAULIC SEEDING:
SURFACE ROUGHENING IS PARTICULARLY IMPORTANT WHEN HYDRAULICALLY
SEEDING, AS A ROUGHENED SLOPE WILL PROVIDE SOME NATURAL COVERAGE
FOR LIME, FERTILIZER, FLEXIBLE GROWTH MEDIUM (FGM) AND SEED. THE
SURFACE SHOULD NOT BE COMPACTED OR SMOOTH. FINE SEEDBED
PREPARATION IS NOT NECESSARY FOR HYDRAULIC SEEDING OPERATIONS; SOIL
CLODS, STONES, AND IRREGULARITIES PROVIDE CAVITIES IN WHICH SEEDS CAN
LODGE.
RATE OF FGM APPLICATION SHOULD VARY BY TYPE AND SHOULD ADHERE TO
SEEDING SPECIFICATIONS TABLE.
IF A MACHINERY BREAKDOWN OF 1/2 TO 2 HOURS OCCURS, ADD 50% MORE
SEED TO THE TANK, BASED ON THE PROPORTION OF THE SLURRY REMAINING.
THIS SHOULD COMPENSATE FOR DAMAGE TO SEED. BEYOND 2 HOURS, A FULL
RATE OF NEW SEED MAY BE NECESSARY.
LIME IS NOT NORMALLY APPLIED WITH A HYDRAULIC SEEDER BECAUSE IT IS
ABRASIVE. IT CAN BE BLOWN OR BROADCAST ONTO STEEP SLOPES IN DRY
FORM.
MAINTENANCE:
GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY
ESTABLISHED UNTIL SOIL COVER HAS BEEN MAINTAINED FOR ONE FULL YEAR
FROM PLANTING. INSPECT SEEDED AREAS FOR FAILURE AND MAKE
NECESSARY REPAIRS AND RESEEDINGS WITHIN THE SAME SEASON, IF
POSSIBLE.
RE-SEEDING - IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE OF
PLANT MATERIALS AND QUANTITIES OF LIME AND FERTILIZER. RE-ESTABLISH
THE STAND AFTER SEEDBED PREPARATION OR OVER-SEED THE STAND.
CONSIDER SEEDING TEMPORARY, ANNUAL SPECIES IF THE TIME OF YEAR IS
NOT APPROPRIATE FOR PERMANENT SEEDING.
IF VEGETATION FAILS TO GROW, SOIL MUST BE TESTED TO DETERMINE IF
ACIDITY OR NUTRIENT IMBALANCE IS RESPONSIBLE.
FERTILIZATION - ON THE TYPICAL DISTURBED SITE, FULL ESTABLISHMENT
USUALLY REQUIRES RE-FERTILIZATION IN THE SECOND GROWING SEASON.
FINE TURF REQUIRES ANNUAL MAINTENANCE FERTILIZATION. USE SOIL TESTS
IF POSSIBLE OR FOLLOW THE GUIDELINES GIVEN FOR THE SPECIFIC SEEDING
MIXTURE.

GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCEWITH THE NCG01 CONSTRUCTION GENERAL PERMITImplementing the details and specifications on this plan sheet will result in the constructionactivity being considered compliant with the Ground Stabilization and Materials Handlingsections of the NCG01 Construction General Permit (Sections E and F, respectively). Thepermittee shall comply with the Erosion and Sediment Control plan approved by the delegatedauthority having jurisdiction. All details and specifications shown on this sheet may not applydepending on site conditions and the delegated authority having jurisdiction.GROUND STABILIZATION SPECIFICATIONStabilize the ground sufficiently so that rain will not dislodge the soil. Use one of thetechniques in the table below:POLYACRYLAMIDES (PAMS) AND FLOCCULANTS1. Select flocculants that are appropriate for the soils being exposed during construction,selecting from the NC DWR List of Approved PAMS/Flocculants.2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.3. Apply flocculants at the concentrations specified in the NC DWR List of ApprovedPAMS/Flocculants and in accordance with the manufacturer's instructions.4. Provide ponding area for containment of treated Stormwater before discharging offsite.5. Store flocculants in leak-proof containers that are kept under storm-resistant cover orsurrounded by secondary containment structures.HAZARDOUS AND TOXIC WASTE1. Create designated hazardous waste collection areas on-site.2. Place hazardous waste containers under cover or in secondary containment.3. Do not store hazardous chemicals, drums or bagged materials directly on the ground.EQUIPMENT AND VEHICLE MAINTENANCE1. Maintain vehicles and equipment to prevent discharge of fluids.2. Provide drip pans under any stored equipment.3. Identify leaks and repair as soon as feasible, or remove leaking equipment from theproject.4. Collect all spent fluids, store in separate containers and properly dispose as hazardouswaste (recycle when possible).5. Remove leaking vehicles and construction equipment from service until the problemhas been corrected.6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products toa recycling or disposal center that handles these materials.LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE1. Never bury or burn waste. Place litter and debris in approved waste containers.2. Provide a sufficient number and size of waste containers (e.g dumpster, trashreceptacle) on site to contain construction and domestic wastes.3. Locate waste containers at least 50 feet away from storm drain inlets and surface watersunless no other alternatives are reasonably available.4. Locate waste containers on areas that do not receive substantial amounts of runoff fromupland areas and does not drain directly to a storm drain, stream or wetland.5. Cover waste containers at the end of each workday and before storm events or providesecondary containment. Repair or replace damaged waste containers.6. Anchor all lightweight items in waste containers during times of high winds.7. Empty waste containers as needed to prevent overflow. Clean up immediately ifcontainers overflow.8. Dispose waste off-site at an approved disposal facility.9. On business days, clean up and dispose of waste in designated waste containers.PAINT AND OTHER LIQUID WASTE1. Do not dump paint and other liquid waste into storm drains, streams or wetlands.2. Locate paint washouts at least 50 feet away from storm drain inlets and surface watersunless no other alternatives are reasonably available.3. Contain liquid wastes in a controlled area.4. Containment must be labeled, sized and placed appropriately for the needs of site.5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes fromconstruction sites.PORTABLE TOILETS1. Install portable toilets on level ground, at least 50 feet away from storm drains, streamsor wetlands unless there is no alternative reasonably available. If 50 foot offset is notattainable, provide relocation of portable toilet behind silt fence or place on a gravel padand surround with sand bags.2. Provide staking or anchoring of portable toilets during periods of high winds or in highfoot traffic areas.3. Monitor portable toilets for leaking and properly dispose of any leaked material. Utilize alicensed sanitary waste hauler to remove leaking portable toilets and replace withproperly operating unit.HERBICIDES, PESTICIDES AND RODENTICIDES1. Store and apply herbicides, pesticides and rodenticides in accordance with labelrestrictions.2. Store herbicides, pesticides and rodenticides in their original containers with the label,which lists directions for use, ingredients and first aid steps in case of accidentalpoisoning.3. Do not store herbicides, pesticides and rodenticides in areas where flooding is possibleor where they may spill or leak into wells, stormwater drains, ground water or surfacewater. If a spill occurs, clean area immediately.4. Do not stockpile these materials onsite.CONCRETE WASHOUTS1. Do not discharge concrete or cement slurry from the site.2. Dispose of, or recycle settled, hardened concrete residue in accordance with local andstate solid waste regulations and at an approved facility.3. Manage washout from mortar mixers in accordance with the above item and in additionplace the mixer and associated materials on impervious barrier and within lot perimetersilt fence.4. Install temporary concrete washouts per local requirements, where applicable. If analternate method or product is to be used, contact your approval authority for reviewand approval. If local standard details are not available, use one of the two types oftemporary concrete washouts provided on this detail.5. Do not use concrete washouts for dewatering or storing defective curb or sidewalksections. Stormwater accumulated within the washout may not be pumped into ordischarged to the storm drain system or receiving surface waters. Liquid waste must bepumped out and removed from project.6. Locate washouts at least 50 feet from storm drain inlets and surface waters unless itcan be shown that no other alternatives are reasonably available. At a minimum, installprotection of storm drain inlet(s) closest to the washout which could receive spills oroverflow.7. Locate washouts in an easily accessible area, on level ground and install a stoneentrance pad in front of the washout. Additional controls may be required by theapproving authority.8. Install at least one sign directing concrete trucks to the washout within the project limits.Post signage on the washout itself to identify this location.9. Remove leavings from the washout when at approximately 75% capacity to limitoverflow events. Replace the tarp, sand bags or other temporary structuralcomponents when no longer functional. When utilizing alternative or proprietaryproducts, follow manufacturer's instructions.10. At the completion of the concrete work, remove remaining leavings and dispose of in anapproved disposal facility. Fill pit, if applicable, and stabilize any disturbance caused byremoval of washout.EARTHEN STOCKPILE MANAGEMENT1. Show stockpile locations on plans. Locate earthen-material stockpile areas at least 50feet away from storm drain inlets, sediment basins, perimeter sediment controls andsurface waters unless it can be shown no other alternatives are reasonably available.2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of fivefeet from the toe of stockpile.3. Provide stable stone access point when feasible.4. Stabilize stockpile within the timeframes provided on this sheet and in accordance withthe approved plan and any additional requirements. Soil stabilization is defined asvegetative, physical or chemical coverage techniques that will restrain acceleratederosion on disturbed soils for temporary or permanent control needs.AABELOW GRADE WASHOUT STRUCTURE1:1SIDE SLOPE(TYP.)10 MILPLASTICLINING3'-0"MIN.& X'MAX.SECTION A-ANOT TO SCALEABOVE GRADE WASHOUT STRUCTURENOT TO SCALESECTION B-BHIGHCOHESIVE &LOW FILTRATIONSOIL BERM8"6"2'HIGHCOHESIVE &LOW FILTRATIONSOIL BERM1:1 SIDESLOPE(TYP.)10 MILPLASTIC LININGBB3'-0" MIN.&X' MAX.ASANDBAGS (TYP.)OR STAPLESSANDBAGS (TYP.)OR STAPLESSANDBAGS (TYP.)OR STAPLESSANDBAGS (TYP.)OR STAPLESNOTES:1.
