STOCKPILE AREA NOTES:
1. MAXIMUM SIDE SLOPES: 2:1.
2. MAXIMUM HEIGHT SHALL NOT EXCEED 35 FEET.
3. ENSURE STOCKPILE AREAS ARE SUFFICIENTLY STABILIZED TO MINIMIZE
SEDIMENT RUNOFF.
4. STOCKPILE AREAS SHALL BE KEPT WITHIN PROPOSED LIMITS SHOWN ON
PLANS
STOCKPILE MAINTENANCE:
1. SEEDING OR COVERING OF PILES WITH TARPS OR MULCH IS REQUIRED AND
WILL REDUCE EROSION PROBLEMS. TARPS SHOULD BE KEYED IN AT THE TOP
OF THE SLOPE TO KEEP WATER FROM RUNNING UNDERNEATH THE PLASTIC.
2. IF A STOCKPILE IS TO REMAIN FOR FUTURE USE AFTER THE PROJECT IS
COMPLETE (BUILDERS, ETC), THE FINANCIAL RESPONSIBLE PARTY MUST
NOTIFY FUQUAY-VARINA OF A NEW RESPONSIBLE PARTY FOR THAT
STOCKPILE.
3. THE APPROVED PLAN SHALL PROVIDE FOR THE USE OF STAGED SEEDING AND
MULCHING ON A CONTINUAL BASIS WHILE THE STOCKPILE IS IN USE.
4. ESTABLISH AND MAINTAIN A VEGETATIVE BUFFER AT THE TOE OF THE SLOPE
(WHERE PRACTICAL).
NOTES:
1. AREAS WILL BE STABILIZED PER THE GROUND STABILIZATION CHART
AFTER ANY GRADING.
2. ALL BASINS SHOULD BE CLEANED AFTER ANY RAIN EVENT THAT
EXCEEDS 1" IN 24 HOURS.
3. SEDIMENT BASINS WILL BE INSTALLED WHERE STORM DRAINAGE
PIPE IS LOCATED. I.E. PIPES WILL BE LEFT SHORT AND EXTENDED
THROUGH BASIN AREAS AFTER SITE HAS BEEN STABILIZED.
4. MAXIMUM IMPERVIOUS AREA SQUARE FOOTAGE ON EACH
INDIVIDUAL LOT WILL BE STRINGENTLY ENFORCED WITH NO
EXCEPTIONS INTO PERPETUITY.
5. (LOD) INDICATES THE LIMITS OF ULTIMATE DISTURBANCE FOR
PURFOY SOUTH.

3:1 TO 2:1 SLOPE --ADAPTIVE PLANTS (SHRUBS AND VINES)
2:1 TO 1.5:1--RIP RAP
STEEPER THAN 1.5 TO 1-RETAINING WALL
SEDIMENT BASIN REMOVAL:
1. REMOVE BASINS ONLY AFTER SITE IS STABILIZED AND WITH
PERMISSION FROM WAKE COUNTY ENGINEER.
2. REMOVE TARP AND ALL NON DIRT AND/OR ROCK MATERIAL.
3. USE BACKHOE TO FILL IN AND LEVEL BACK TO NATURAL GROUND
ELEVATION.
4. SEED AND STRAW APPROPRIATELY.

GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE
WITH THE NCG01 CONSTRUCTION GENERAL PERMIT
Implementing the details and specifications on this plan sheet will result in the construction
activity being considered compliant with the Ground Stabilization and Materials Handling
sections of the NCGOI Construction General Permit (Sections E and F, respectively). The
permittee shall comply with the Erosion and Sediment Control plan approved by the delegated
authority having jurisdiction. All details and specifications shown on this sheet may not apply
depending on site conditions and the delegated authority having jurisdiction.
EARTHEN STOCKPILE MANAGEMENT
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least 50
feet away from storm drain inlets, sediment basins, perimeter sediment controls and
surface waters unless it can be shown no other altematives are reasonably available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of five
feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the firrieframes provided on this sheet and in accordance with
the approved plan and any additional requirements. Soil stabilization is defined as
vegetative, physical or chemical coverage techniques that will restrain accelerated
erosion on disturbed soils for temporary or permanent control needs.
I . ..... — -------
HERBICIDES, PESTICIDES AND RODENTICIDES
1. Store and apply herbicides, pesticides and rodenticides in accordance with label
restrictions.
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 accidental
poisoning.
3. Do not store herbicides, pesticides and rodenticides in areas where flooding is possible
or where they may spill or leak into wells, stormwater drains, ground water or surface
water. If a spill occurs, clean area immediately.
4. Do not stockpile these materials onsite.
POLYACRYLAMIDES (PAMS) AND FLOCCULANTS
1. Select flocculants that are appropriate for the soils being exposed during construction,
selecting from the NC DWR List of Approved PAMSIFlocculants.
2. Apply flocs ulants at or before the inlets to Erosion and Sediment Control Measures.
3. Apply flocculants at the concentrations specified in the NC DWR List of Approved
PAMSIFlocculants 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 or
surrounded by secondary containment structures.
EQUIPMENT AND VEHICLE MAINTENANCE
1. 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 the
project,
4. Collect all spent fluids, store in separate container's and properly dispose as hazardous
waste (recycle when possible).
& Remove leaking vehicles and construction equipment from service until the problem
has been corrected.
6. Bring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products to
a recycling or disposal center that handles these materials,
