6. Any borrow material brought onto this site must be from a legally operated mine or other approved source. N
Any soil waste that leaves this site can be transported to a permitted mine or separately permitted construction 6
sites without additional permits under NCGS 74-49(7)(d). Disposal at any other location would have to be 1
included as a permit revision for this approval.
7. This permit allows for a land disturbance, as called for on the application plan, not to exceed 5.08 acres.
Exceeding that acreage will be a violation of this permit and would require a revised plan and additional
application fee. Any addition in impervious surface,over that already noted on the approved plan,would also
require a revised plan to verify the appropriateness of the erosion control measures and stormwater retention
measures(NCGS 113A-54.1(b)).
8. The construction detail for the proposed silt fence requires reinforcing wire and steel posts a maximum of eight
(8)feet apart. Omission of the reinforcing wire is a construction change that necessitates more posts for support,
i.e., the spacing distance needs to be reduced to no greater than six(6) feet apart (E&SC Planning & Design
Manual 6.63,Rev. 6/06).
9. Because the sediment traps and basins are shown on the plan as the primary sedimentation and erosion control
devices on this project, it is necessary that the traps and basins and their collection systems be installed before
any other grading takes place on site, and that every structure that receives more than one acre of drainage is
built so that each dewaters only from the surface(NCG010000). If that proves to be impractical,a revised plan
must be submitted and approved that addresses erosion and sediment control needs during the interim period
until the traps and basins are fully functioning(113A-54.1(b)).
10. A graveled construction entrance must be located at each point of access and egress available to construction
vehicles during the grading and construction phases of this project. Access and egress from the project site at
a point without a graveled entrance will be considered a violation of this approval. Routine maintenance of the
entrances is critical(113A-54.1(b)).
11. As a condition of the NPDES General Stormwater Permit(NCG010000),the fmancially responsible party shall
comply with the NCGO 1 Ground Stabilization and Materials Handling requirements that became effective April
1, 2019. The NCG01 Ground Stabilization and Materials Handling standard detail can be printed from the
deq.nc.gov/NCG01 website.
12. As a condition of the NPDES General Stormwater Permit(NCG010000),the fmancially responsible party shall
comply with the NCGO1 Self-Inspection, Recordkeeping and Reporting requirements that became effective
April 1,2019. The NCG01 Self-Inspection,Recordkeeping and Reporting standard detail can be printed from
the deq.nc.gov/NCG01 website.
13. As a part of routine monitoring of the approved land-disturbing activity,the financially responsible party shall
assure inspections of the area covered by the approved plan after each phase of the plan has been completed
and after establishment of temporary ground cover in accordance with North Carolina General Statute 113A-
54.1(e).
