TYPICAL CONSTRUCTION SEQUENCE FOR SINGLE
FAMILY LOTS SEDIMENT AND EROSION CONTROL
1. SCHEDULE A PRE -CONSTRUCTION CONFERENCE WITH THE TOWN OF FUQUAY-VARINA. OBTAIN A LAND DISTURBING PERMIT.
2, INSTALL MEASURES AS SHOWN ON THE APPROVED PLAN. CLEAR ONLY AS NECESSARY TO INSTALL THESE DEVICES. SEED TEMPORARY DIVERSIONS,
BERMS AND BASINS IMMEDIATELY AFTER CONSTRUCTION.
3- CALL ENGINEERING CONSTRUCTION INSPECTOR FOR A COMPLIANCE INSPECTION,
4. MAINTAIN DEVICES AS NEEDED FOR ALL PHASES OF PROJECT- REMOVE EROSION CONTROL DEVICES WITH ENGINEERING CONSTRUCTION
INSPECTOR APPROVAL ONLY.
5- MAINTAIN RAIN GAUGE AND SELF -INSPECTION RECORDS PER NPDES REQUIREMENTS,
6. STABILIZE SITE AS AREAS ARE BROUGHT UP TO FINISH GRADE WITH VEGETATION, PAVING, DITCH LININGS, ETC. SEED AND MULCH DENUDED AREAS
PER GROUND STABILIZATION TIME FRAMES ON APPROVED PLAN.
7. WHEN CONSTRUCTION IS COMPLETED, AND ALL AREAS ARE STABILIZED, CALL ENGINEERING CONSTRUCTION INSPECTOR FOR INSPECTION.
8- IF SITE IS APPROVED, REMOVE TEMPORARY DIVERSIONS, SILT FENCE, SEDIMENT BASINS. ETC., AND SEED OUT OR STABILIZE ANY RESULTING BARE
AREAS. ALL REMAINING PERMANENT EROSION CONTROL DEVICES; SUCH AS VELOCITY DISSIPATORS, SHOULD NOW BE INSTALLED.
9- WHEN VEGETATION HAS BECOME PERMANENTLY ESTABLISHED, CALL FOR A FINAL SITE INSPECTION BY THE ENGINEERING CONSTRUCTION
INSPECTOR.

GROUND STABILIZATION AND MATERIALS HANDLING PRACTICES FOR COMPLIANCE WITH
THE NCGO1 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 NCG01 Construction General Permit (Sect lons 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 conditlons and the delegated authority having jurisdiction,

Note: After the permanent cessation of construction activities, any areas with temporary

practicable but in no case longer than 90 calendar days after the last land disturbing
activity. Temporary ground stabilization shall be maintained in a manner to render the
surface stable a ga1nst accelerated erosion until permanent g round stabilization is achieved.
GROUND STABILIZATION SPECIFICATION
Stabilize the ground sufficiently so that rain
will not dislodge the soil. Use one of the
techniques in the table below:

• uniform and evenly distributed ground cover
sufficient to restrain erasion
• Structural methad s such as concrete, asphalt or

FOLYACRYLAMIDES (PAfMS) AND FLOCCULANTS
1. Select flocculants that are appropriate for the soils being exposed during
construction, selecting from the NC DWR List of Approved PAMS/FIocculanM
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 Approved
PAINTS/Flocculonm and 1n accordance with the manufacturer's instructions.
4. Provide ponding area for containment of treated 5tormwater before discharging
offslte.
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 containers and properly dispose as
hazardous waste (recycle when possible).
5- Remove leaking vehicles and construction equipment from service until the problem
has been corrected.
6. $ring used fuels, lubricants, coolants, hydraulic fluids and other petroleum products
to a recycling or disposal center that handles these materials.
LITTER, BUILDING MATERIAL AND LAND CLEARING WASTE
1. Never bury or burn waste. place litter and debris in approved waste containers.
1 Provide a sufficient number and size of waste containers (e.g dumpster, trash
receptacle) on site to contain construction and domestic wastes.
1 Locate waste containers at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
4. Locate waste containers on areas that do not receive substantial amounts of runoff
from upland areas and does not drain directly to a storm drain, stream or wetland.
S. Cover waste containers at the end of each workday and before storm events or
provide secondary 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 if
conta inets overflow.
8. Dispose waste off -site at an approved disposal facility.
9. On business days, cleanup and dispose of waste in designated waste containers.
PAINT AND OTHER LIQUID WASTE
1. 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
waters unless 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 from
construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 5D feet away from storm drains,
streams or wetlands unless there is no alternative reasonably available. If 50 foot
