EROSION AND SEDIMENTATION CONTROL NARRATIVE
PROJECT DESCRIPTION
The purpose of this project is for the construction of a Gas Station.
The project Is owned by Herritage, LLC. The site is currently vacant.
Approximately 4.92 acres will be disturbed during construction.
The pro1'ect is scheduled to begin construction in Summer 2021 with project completion and final
stabilization by Winter 2021. The erosion and sediment control program for this project will include
the installation of a suitable construction entrance, silt fence, inlet protection with seeding.
ADJACENT PROPERTY
The adjacent property is vacant.
SOILS
The soil at this site is a sandy clay.
EROSION AND SEDIMENT CONTROL MEASURES
All vegetative and structural erosion and sediment control practices shall be constructed and
maintained by the contractor according to these plans and specifications and the minimum
standards of the Dept. of Environmental Management, Land Quality Section and Town of
Spring Hope. The contractor shall also follow any additional requirements as outlined by the Project
Engineer.
Structural Practices
1. Vehicle wheels shall be clean when leaving the site to prevent the tracking of mud on paved
roads.
2. Construction Road Stabilization: Construction traffic shall be limited to stabilized areas. At a
minimum, a temporary gravel construction entrance shall be provided as shown on this
drawing.
3. Silt Fence: Silt fences shall be provided where shown and as needed on the site Ian. These
barriers shall be used to contain sediment. P
4. Rip Rap/Gravel Filter Sediment Basins: Construct basin to the shape and dimensions shown in
the details. The basin is to be placed below the existing ditch flow line by 2' with the berm built
above as dimensioned.

Seeding Schedule
Ongoing Activity Land left exposed shall be planted or otherwise provided with temporary ground cover, devices, or
structures sufficient to restrain erosion within the applicable time period after completetion of any phase of grading or
period of inactivity as follows. seven (7) days for steep slope or inclination. Ten (10) days for a moderate slope,
fourteen (14) days for land with no slope or inclinination. For purposes of this section, a moderate slope means an
inclined area, the inclination oif which is less than or equal to three (3) units of horizontal distance to one (1) unit of
vertical distance, and a steep slope means an inclined area, the inclination of which is greater than three (3) units of
horizontal distance to one (1) unit of vertical distance. No other criteria apply.
Completed Activity. For any area of land -disturbing activity where grading activities have been completed, temporary or
permanent ground cover sufficient to restrain erosion shall be provided as soon as practicable, but in no case later than
seven (7) days after completetion of grading.
Management Strategies
1. Perimeter measures are to be installed prior to grubbing or grading.
2. Tail Ditches shall be stabilized immediately following their construction. As an alternate, rock
check dams may be provided at their outlets and/or the terminal downstream end of
disturbance until ground cover is implemented.
3. Stockpile and/or waste areas must be maintained within the limits of the areas protected by the
proposed measures and otherwise temporarily seeded if to be left stockpiled over 15 days.
4. Construction shall be planned so that grading operations can begin and end as quickly as
ppossible.
5. Silt Fences shall also be installed prior to or as a first step in construction.
6. The Contractor shall be responsible for the installation and maintenance of all erosion and
sediment control practices.
Vegetative Ground Cover
Immediately following grading, all areas shall receive either permanent or temporary seeding, as
applicable, as follows:
TEMPORARY SEEDING SPECIFICATIONS
BETWEEN MAY 1 AND AUGUST 15, ADD 40 LB/ACRE GERMAN MILLET. PRIOR TO MAY 1 OR AFTER AUGUST 15, ADD
120 LB/ACRE RYE (GRAIN).
FALL IS BEST FOR TALL FESCUE AND LATE WINTER FOR LESPEDEZAS. OVERSEEDING OF KOBE LESPEDEZAS OVER
THE FALL SEEDED TALL FESCUE IS VERY EFFECTIVE. USE UNHULLED BERMUDAGRASS SEED IN FALL.
SOIL AMENDMENTS
APPLY LIME AND FERTILIZER ACCORDING TO TESTS, OR APPLY 2,000 LB/ACRE GROUND AGRICULTURE LIMESTONE
AND 750 LB/ACRE 10-10-10 FERTILIZER
MULCH
APPLY 4,000 LB/ACRE GRAIN STRAW, OR EQUIVALENT COVER OF ANOTHER SUITABLE MULCHING MATERIAL.
ANCHOR MULCH BY TACKING WITH ASPHALT, ROVING OR NETTING. NETTING IS THE PREFERRED ANCHORING
METHOD ON STEEP SLOPES.
MAINTENANCE
REFERTILIZE IF GROWTH IS NOT FULLY ADEQUATE. RESEED, REFERTILIZE AND MULCH IMMEDIATELY
FOLLOWING EROSION OR OTHER DAMAGE.
PERMANENT SEEDING SPECIFICATIONS
FESCUE - 200 Lbs./Ac.
CENTIPEDE - 20 Lbs./Ac.
SOIL AMENDMENTS
APPLY LIME AND FERTILIZER ACCORDING TO SOIL TEST.
MAINTENANCE
IF GROWTH IS LESS THAN FULLY ADEQUATE, REFERTILIZE THE SECOND YEAR. ACCORDING TO SOIL TESTS OR
TOPDRESS WITH 500 LB/ACRE 10-10-10 FERTILIZER. MOW AS NEEDED.
REPLACE, FERTILIZE, AND MULCH DAMAGED AREAS IMMEDIATELY.
Maintenance
1. Reseed and mulch bare spots larger than 9 square feet (limited to 5% maximum of site area.)
2. Maintain all seeded areas until uniform stand Is acceptable.
3. If growth is not established by final project inspection, continue specified attention until the
stand is acceptable.
4. Correct and repair all undue settling and erosion within 1 year after final inspection.
5. Remove from the site, all erosion control structures after complete stabilization at end of
construction period.
6. Remove silt from sediment pits and from behind check dams when silt is within half depth of
the pit or spillway. Dispose of in an area where silt cannot re-enter pit / trap.

attended by a representative of the financially responsible party and/or the general contractor, grading sub -contractor, erosion control
sub -contractor and the Engineer.
2. Erosion and Sediment Control (E&SC) permit and a Certificate of Coverage (COC) must be obtained before and land disturbing
activities occur. The COC can be obtained by filling out the electronic Notice of Intent (e-NOI) form at deq.nc.gov/NCGO1. Please note,
the e-NOT form may only be filled out once the plans have been approved. A copy of the E&SC permit, the COC, and a hard copy of the
plan must be kept on site, preferably in a permits box, and accessible during inspection.
J. Per NPDES requirements, a rain gauge, self -inspections records, permit, Certificate of Coverage, and S&E plan are required to be
maintained on site and accessible during inspection. It is recommended that these items be placed in a permits box at the beginning or
entrance of project.
4. The contractor shall conduct self -inspections of the erosion and sedimentation control measures and compete the following combined
self -inspection form found on the DEMLR website https: Llfiles.nc.gov ncdecl Energy72OMineral720and72OLand720Resources/StormwaterZ

on -site and available for inspection at all times. It is recommended a copy be kept in a permits box.
5. Self -inspections for erosion and sedimentation control measures are to be performed at least once every seven calendar days and within
24 hours of every rain event of greater than 1 inch. Any needed repairs shall be made immediately to maintain measures as designed. All
ESC measures shall be maintained as specified in the construction details on this plan. A rain gauge shall be installed at the project site for
monitoring.
6. Contact the DEMLR Raleigh Regional Office at least 48 hours prior to commencing the land disturbing activity. The DEMLR Raleigh
Regional Office can be reached at [phone].
7. Install construction egress/exit, silt fencing with outlets, skimmer sediment basins, and other initial erosion control measures as specified
in the plan. Remove only trees and ground cover necessary to install these devices.
8. Notify the NC DEQ site inspector after measures have been installed and project has started.
9. Begin demolition, clearing, grubbing and grading of site in accordance with the approved S&E control plan. Install temporary diversions
with excelsior matting.
10. Provide all disturbed areas with round cover as per round stabilization table or after completion of an phase of clearing, grubbing or
9 P 9 P y P 9� 9 9
grading. The seeding, seedbed preparation, mulch and/or rolled erosion control product installation must be in accordance with the seeding
schedule provided in this S&E plan. Per the NPDES Permit, ground stabilization will be applied within 14 calendar days from last land
disturbing activity. For steep slopes, that area must be stabilized within 7 calendar days.
11. Start installation of storm drain system beginning with outlet pipe and working uphill toward DI #3. Install inlet and outlet protections for
storm drain system immediately after pipe installation.
12. At the conclusion of grading or if land -disturbing activity is stopped temporary or permanent vegetative cover shall be installed in
accordance with ground stabilization table. Include excelsior matting as shown on plan. Permanent groundcover shall be established in 90
calendar days. However, NPDES groundcover requirements take precedence.
13. Perimeter measures must be left in place until all upland areas are permanently stabilized. After site is permanently stabilized, remove
all temporary erosion control measures and provide permanent seeding where temporary measures have been removed and ground cover is not
adequate. Sediment basins may not be removed or converted to permanent BMPs until all upland areas are permanently stabilized.
14. When DEMLR has approved removal of E&SC measures, remove sediment basins using dewatering silt bag. (See Detail)
15. When the project is complete, the permittee shall contact DEMLR to close out the E&SC Plan. After DEMLR informs the permittee of
the project close out, via inspection report, the permittee shall visit deq.nc.gov/NCGO1 to submit an electronic Notice of Termination (e-NOT).
A $'100 annual general permit fee will be charged until the e-NOT has been filled out.
16. Remaining measures must be removed and resulting bare areas stabilized before permit can be closed.
17. Remove all erosion control measures after the NC DEQ office approval of permanent stabilization.
