I . Obtain all necessary permits and plan approvals. Erosion and Sediment Control
(E&SC) permit and a Certificate of Coverage (COC) must be obtained before any land disturbing activities
occur. 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.
2. Install gravel construction entrances first, then sill fences, reinforced sill fence outlets and wattles.
3. Finish clearing and grubbing any necessary areas on the lots as they are started.
4. Begin lot grading and excavation activities
5. Begin or continue with house construction activities.
6. Finish all rough grading and house construction.
7. Install driveways, walks and patios.
8. Begin fine grading of lot areas
9. Final grassing, mulching and stabilizing of lot. In most cases this will involve the installation of sod on the lot.
The silt fence will remain in place until the lot is sodded or grasshng is stabilized and takes hold.
10. The contractor shall conduct self -inspections of the erosion and sedimentation control measures and complete
the following combined self -inspection form found on the DEMLR website
https: //tiles.ne.gov lncdeg/Energy%20MinefalD/o20andD/u2OLand°/D20Resources/Stormwater/NPDES°/`20
General%20Permits/DEMLR-CSW-Monitoring-Forms-Rev-August-8-2019.pdf. Twelve months of complete
inspection forms shall be kept on Site and available for inspection at all limes. It is recommended a copy be
kept in a permits box. (GS 113A-54.1 (e), 15A NCAC 04B.0131, NCG01 Part III Sections A and B)
11. 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.
12. Inspection and final acceptance letters. When the project is complete, the permittees shall contact DEMLR to
close out the E&SC Plan. After DEMLR informs the permittee of the project close out, via inspection report,
the permiltee shall visit"deq.ne.gov/NCG01" to submit an electronic Notice of termination (e-NOT). A $100
amoral general permit fee will be charged until the e-NOT has been filled out.
A "SELF -INSPECTION REPORT FOR LAND DISTURBING ACTIVITY AS REQUIRED BY
NCGS 113A-54.1"IS AVAILABLE FOR USE. IT CAN BE COMPLETED BY HAND OR
COMPLETED AS AN EXCEL SPREADSHEET.
AN ALTERNATIVE IS TO MAKE NOTATIONS ON THE COPY OF THE APPROVED
EROSION AND
SEDIMENTATION CONTROL PLAN THAT IS KEPT ON THE PROJECT SITE. RULE 15A
NCAC 04B. 0131 STATES THAT "...DOCUMENTATION SHALL BE ACCOMPLISHED BY
INITIALING AND DATING EACH MEASURE OR PRACTICE SHOWN ON A COPY OF THE
APPROVED EROSION AND SEDIMENTATION CONTROL PLAN OR BY COMPLETING,
DATING AND SIGNING AN INSPECTION REPORT THAT LISTS EACH MEASURE,
PRACTICE OR DEVICE SHOWN ON THE APPROVED EROSION AND SEDIMENTATION
CONTROL PLAN."
MAINTENANCE OF EROSION AND SEDIMENTATION CONTROL MEASURES FOR LOT CONSTRUCTION
Gravel Construction Entrance - The gravel pad should remain in a condition to prevent mud or sediment from leaving the construction site.
This may require periodic topdressing with 2-inch stone. After each rainfall, inspect any structure used to trap sediment and clean it out as necessary.
Immediately remove all objectionable materials spilled, washed, or tracked onto public roadways.
Silt Fence - Sediment fences should be inspected at least once a week and after each rainfall event. Any repairs should be made immediately.
Damaged or decomposed fabric should be replaced promptly. Any sediment deposits that build up against the fence should be removed and disposed
of properly to insure that the removed sediment does not wash back against the fence. Adequate storage volume should be provided for behind the fence
at tall times. Take care to not undermine the fence during cleanout operations.
Sodding - The sod should be properly maintained to insure that the grass take holds in the areas being seemed. The sod should be watered as necessary
to maintain adequate moisture in the root zone and prevent dormancy of the sod. The sod should not be mowed to close, since this could inhibit adequate
growth and stabilization of the root bed. The sod should be limed and fertilized as per soil type recommendations and type of gmss recommendations when
and if possible.
Grassing and Mulching - The area to receive grassing and mulching should be properly fertilized and limed as necessary as an initial step in soil preparation.
Once the grassing has been placed, the area should be maintained as needed to insure that all areas are germinating properly. Any bare areas should be repaired,
and reseeded as soon as possible. If the time of year does not permit the establishment of a permanent grass, then a temporary grassing should be used until the
growing season permits the use of a permanent grass.
Diversion Berms - Diversion berms shall be inspected weekly or after each runoff producing rainfall to insure that they are operating as designed and that there
have been no breaches in the berm. Berms shall not exceed 18" in height, and shall be placed in locations that will not interfere with home construction activities.
One the house conmhuction is completed and the lot is ready to receive sod, then the berm shall be removed and the material incorporated into the graded lot area
and covered immediately with sod. All proper care shall be taken to insure that the berms are installed according to the applicable detail with the berm material
compacted sufficiently to insure that the berm remains in place during the course of the construction activities.
General - All measures will be inspected and corrections made after runoff producing rainfalls or at least once per week minimum. The builder will insure that the
P Pr ng
construction activities many particular lot do not adversely affect any of the installed erosion control measures. If lot construction dictates, measures will be relocated
on the lot to insure that the potential for sedimentation runoff is eliminated as much as possible. Silt fences and gravel construction entrances will be maintained as suggested
in the erosion control manual. Sodding, seeding and mulching will be maintained to insure proper ground stabilizing cover.
