Dear Mr. Oliver,
This office has reviewed the subject erosion and sedimentation control plan. We find
the plan to be acceptable with modifications and hereby issue this letter of Approval with
Modifications.The Modifications Required for Approval are listed on the attached page.This
plan approval shall expire three (3) years following the date of approval, if no land-
disturbing activity has been undertaken, as is required by Title 15A NCAC 4B .0129.
As of April 1, 2019, all new construction activities are required to complete and submit an
electronic Notice of Intent(eNOI) form requesting a Certificate of Coverage (COC) under the
NCG010000 Construction General Permit. After the form is reviewed and found to be
complete, you will receive a link with payment instructions for the $100 annual permit fee.
After the fee is processed,you will receive the COC via email. As the Financially Responsible
Party shown on the FRO form submitted for this project, you MUST obtain the COC prior to
commencement of any land disturbing activity. The eNOI form may be accessed at
deq.nc.gov/NCG01. Please direct questions about the eNOI form to the Stormwater Program
staff in the Raleigh central office. If the owner/operator of this project changes in the future,
the new responsible party must obtain a new COC.

Title 15A NCAC 4B.0118(a) and the NCG01 permit require that the following documentation
be kept on file at the job site:
1. The approved E&SC plan as well as any approved deviation.
2. The NCG01 permit and the COC, once it is received.
3. Records of inspections made during the previous 12 months.
Also, this letter gives the notice required by G.S. 113A-61.1(a) of our right of periodic
inspection to ensure compliance with the approved plan.
North Carolina's Sedimentation Pollution Control Act is performance-oriented, requiring
protection of existing natural resources and adjoining properties. If, following the
commencement of this project, it is determined that the erosion and sedimentation control
plan is inadequate to meet the requirements of the Sedimentation Pollution Control Act of
1973 (North Carolina General Statute 113A-51 through 66),this office may require revisions
to the plan and implementation of the revisions to ensure compliance with the Act
Acceptance and approval of this plan is conditioned upon your compliance with Federal and
State water quality laws, regulations, and rules. In addition, local city or county ordinances
or rules may also apply to,this land-disturbing activity. This approval does not supersede
any other permit or approval.
Please note that this approval is based in part on the accuracy of the information provided
in the Financial Responsibility Form, which you provided. You are requested to file an
amended form if there is any change in the information included on the form. In addition,it
would be helpful if you notify this office of the proposed starting date for this project.
Your cooperation is appreciated.

1. Provide stabilized inlets for the proposed skimmer basin that extend into the floor
of the basin. All runoff to proposed sediment basin must enter through a stabilized
inlet. (G.S. 113A-57.(3)}
2. Revise construction sequence to include the following language: notify NCDEQ LQS
inspector 48 hrs before project starts; no major grading activities or basin
construction are to take place during wet weather or periods of predicted wet
weather i.e. Hurricanes; file for NPDES NCG010000 e-Notice of Termination when
final close out inspection report is received from NCDEQ LQS; install inlet protection
by the end of the workday for all constructed SW inlets; specify order in which
significant E&SC measures must be installed and related areas in which they protect
i.e. TCE,then perimeter controls,stabilized outlets,then basins,then conveyances,
proceed with clearing and grubbing for Phase X, install additional measures X, then
XX, then XXX for Phase II, continue to add stabilization and seeding for areas not
stabilized; prior to construction of the sediment basin,silt fence shall be installed
below the toe of the proposed embankment of the sediment basin to prevent
sedimentation damage during sediment trap construction; sediment basin and trap
embankments shall be provided with adequate groundcover immediately upon
construction;after the drainage areas to the basins and traps have been
permanently stabilized,dewater the basins. Fill the basins using stockpiled soil and
bring to finish grade in compacted lifts. Smooth the basin sites to blend with the
surrounding area, ensuring the basin sites will not pond water,and immediately
permanently stabilize; dewatering operations must be discharged into adequate
stilling basin or comparable measure to prevent the discharge of sediment; inspect
and cleanout SW system before bringing online; specify when E&SC measures are to
be converted into post-construction SW BMP's i.e. sediment basin converted to
retention pond or decommissioned-requires separate individual sequence for
conversion; site must be"storm ready"before any extended breaks in construction
activities including weekends. {15A NCAC 04B .0106(a)(2)}
3. Provide final site conditions plan sheet showing either the basin being
decommissioned or converted over to a post-construction stormwater BMP. {G.S.
113A-57.(4)}
4. Hatch or highlight all areas required to meet NPDES NCG010000 7-day stabilization
requirement. {NPDES NCG010000)
5. Note on plan that any borrow and or waste must come from or go to a permitted site
and or facility. {15A NCAC 04B .0110}
6. Provide verification that a geotechnical engineer or a professional engineer with
equivalent design experience has designed or approved retaining wall design. {G.S.

Fact Sheet on the New NCGO1 Permit DEQ,

Opammanl of En.nonmen:al Owil�
The NC Construction General Permit(also known as"NCG01")was renewed on April 1,2019.The updated permit
does not significantly change the measures that are required to be implemented on construction sites. However,
there are some organizational and technical updates to the permit as described below. Most notably, there is a new
process in which construction sites will obtain official coverage under an NCGO1 permit through an electronic
process. DEMLR worked with a broad team of stakeholders to make all of these updates. If you have questions,
contact Annette Lucas at Annette.lucas(ancdenr.gov or(919) 707-3639.
