DRAW DOWN OF SEDIMENT BASINS FOR MAINTENANCE OR CLOSE OUT
Sediment basins and traps that receive runoff from drainage areas of one acre or more shall use outlet structures that withdraw water from the surface when these devices need to be drawn down for maintenance or close out unless this Is infeasible.The circumstances In which it Is not
feasible to withdraw water from the surface shall be rare(for example,times with extended cold weather). Non-surface withdrawals from sediment basins shall be allowed only when all of the following criteria have been met:
(a) The E&SC plan authority has been provided with documentation of the non-surface withdrawal and the specific time periods or conditions In which it will occur.The non-surface withdrawal shall not commence until the E&SC plan authority has approved these Items,
(b) The non-surface withdrawal has been reported as an anticipated bypass In accordance with Part III,Section C,Item(2)(c)and(d)of this permit,
(c) Dewatering discharges are treated with controls to minimize discharges of pollutants from stormwater that Is removed from the sediment basin. Examples of appropriate controls include properly sited,designed and maintained dewatering tanks,weir tanks,and filtration systems
(d) Vegetated,upland areas of the sites or a properly designed stone pad Is used to the extent feasible at the outlet of the dewatering treatment devices described In Item(c)above,
(e) Velocity dissipation devices such as check dams,sediment traps,and riprap are provided at the discharge points of all dewatering devices,and
(f) Sediment removed from the dewatering treatment devices described in Item(c)above indisposed of in a manner that does not cause deposition of sediment Into waters of the United States.

SEED BED PREPARATION:
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 1-1 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.
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.
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 raking, harrowing, or other suitable methods for fine grading. The finished grade shall
be a smooth even soil surface with a loosen uniformly fine texture.All ridges and depressions shall be removed and filled to provide the approved surface drainage.
Planting is to be done immediately after finished grades are obtained and seedbed preparation is completed.

SEED BED PREPARATION:
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 i 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.
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

seedbed preparation is completed.
NOTES:
1. Permanent seeding,sodding or other means of stabilization are required when all construction work is completed according to the NPDES timeframe's table.
2. A North Carolina Department of Agriculture soils test(or equal)is highly recommended to be obtained for all areas to be seeded,sprigged,sodded or planted.
3. Use a seeding mix that will produce fast growing nurse crops and includes non-invasive species that will eventually provide a permanent groundcover.Soil blankets may be used in lieu of nurse
crops.Mat,tack or crimp mulch,as needed to stabilize seeded areas until root establishment.Mulch must be applied uniformly over the soil with a cover density of at least 80%.
4. Ground cover shall be maintained until permanent vegetation is established and stable against accelerated erosion.
