RE:Grading Permit#48-22 Revision#1.The Sidbury Station Phase II Stockpile
Dear Libby Shelton:
This office has reviewed the revised erosion and sedimentation control plan. We find the plan to
be acceptable and hereby issue this land-disturbing permit with modifications. Please read the permit
conditions carefully,return the signed color original to our office and keep the copy for your records. A
copy of the enclosed land-disturbing permit must be posted at the job site.This letter gives the notice
required by GS 113A-61.1(a)and the New Hanover County Erosion and Sedimentation Control Ordinance
Article VIII Section 8.21 of our right of periodic inspection to ensure compliance with the approved plan.
As of April 1, 2019, all new construction activities are required to complete and submit an
electronic Notice of Intent(eN01)form requesting a Certificate of Coverage (COC)under the NCG010000
Construction General Permit. The COC must be obtained prior to the commencement of any land-
disturbing activity on the above-named project, according to State Stormwater requirements.The NOI
form may be accessed at deq.nc.gov/NCG01. Please direct questions about the NOI form to Paul Clark at
Paul.clark('ncdenr.gov. After you submit a complete and correct NOI Form,you will receive a link with
payment instructions for the $100 annual permit fee. After the fee is received,you will receive the COC
via email. The $100 fee will be charged annually until the project receives a final land-disturbance
inspection. Once the project is stabilized and receives the final land-disturbance inspection,you should
file a Notice of Termination(NOT)with the State to final out the project.
A copy of the enclosed land-disturbing permit,a copy of the approved erosion and sedimentation
control plan as well as any approved deviations, records of inspections made during the previous 12
months with the States Certificate of Compliance(COC) number on the report,and a rain gauge must be
posted at the job site as required by 15A NCAC 4B .0118(a), the NCGO1 permit, and the New Hanover
County Erosion and Sedimentation Control Ordinance Article VIII Section 8.19(o).
The land disturbing fee of$23.328 for the original 77.76 acres is due to be paid to New Hanover
County Engineering prior to Plat Recordation.

A preconstruction meeting is optional prior to land-disturbing activity on this project. Please
contact me at(910)798-7139 if you would like to schedule this meeting in our office. If you choose not to
have a preconstruction meeting,you must contact us with the date the land-disturbing activity will take
place onsite and again once the initial erosion control measures are installed.
New Hanover County's Erosion and Sedimentation Control Program 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 Statutes 113A-51 through 66), and the New Hanover County Erosion and Sedimentation Control
Ordinance Article VIII Section 8.19(f),this office may require revisions to the plan and its implementation
of the revisions to ensure compliance with the Act and Ordinance.
This land-disturbing permit will expire within 1 year following the date of approval, if no land-
disturbing activity has been undertaken, as required by the New Hanover County Erosion and
Sedimentation Control Ordinance Article VIII Section 8.18 (d). If no activity takes place within one year
after work has begun onsite,the permit will expire. Please contact this office to reactivate a permit that
has expired.
Acceptance and approval of this erosion control plan is conditioned upon your compliance with
Federal and State water quality laws, regulations and rules and local city or county ordinances or rules.
This land-disturbing permit approval does not supersede any other permits or approvals. It is the owner's
responsibility to have all the permits and approvals that are required, prior to beginning construction.
Please note this approval is based in part on the accuracy of the information provided in the
Financially Responsibility Form,which you provided.You are required to file an amended form if there is
any change in the information included on the form.
Your cooperation is appreciated,

*Enclosed is a Combined Self-Monitoring and Self-Inspection Form that meets the requirements of both the
NPDES Stormwater Permit for Construction Activities, NCG 010000 reporting and the Land Resources Self-
inspection Program that satisfies the requirements of the Sedimentation Pollution Control Act.These are
mentioned below with specific requirements for each program.These reports are the responsibility of the
property owner.They require a rain gauge onsite, inspections and reporting every 7 calendar days and within
24 hours of every 1.0-inch rain per 24-hour period and at specific phases of construction.Additional copies of
this Combined Construction Inspection Report can be found at http://portal.ncdenr.org/web/Ir/erosion .
Reports must be available onsite at all times. If you have questions, please contact New Hanover County
Engineering(910)798-7139 or the Land Quality Section at the NC DEMLR Regional office at(910)796-7215.
*Note the NPDES information from the State for sites disturbing 1 acre or more and the reporting
requirements.All NEW projects permitted after August 3, 2011, must include the following surface water
withdrawal locations and stabilization requirement designations on the plan in order to qualify for coverage
under the most recent NPDES Construction General Permit. All settling basins must have outlet structures that
withdraw water from the surface,with the exception of basins or traps that have a drainage area of less than 1
acre.The NPDES permit also requires ground cover within 14 calendar days on disturbed flat areas and ground
cover within 7 calendar days on all areas within HQW Zones, perimeter dikes,swales, ditches, perimeter slopes
and all slopes steeper than 3:1. Exceptions include slopes that are 10 feet or less in length and not steeper than
2:1 which must be stabilized within 14 calendar days and slopes greater than 50 feet which must be stabilized
within 7 calendar days. It requires inspections of all erosion control measures and reporting every 7 days and
within 24 hours of every 1.0-inch rain event in a 24-hour period.This permit also includes other new
requirements which are listed in the text of the NPDES Stormwater Discharge Permit for Construction Activities
and are included with the original copy of each land-disturbing permit.
*AII 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.The COC must
be obtained prior to the commencement of any land-disturbing activity on the above-named Project, according
to State Stormwater requirements.The NOI form may be accessed at deq.nc.gov/NDG01. Please direct questions
about the NOI form to Paul Clark at [e-mail]. After you submit a complete and correct NOI form,
you will receive a link with payment instructions for the$100 annual permit fee.After the fee is received you will
receive the COC via email.The$100 fee will be charged annually until the project receives a final land-
disturbance inspection. Once the project is stabilized and receives the final land-disturbance inspection, you
should file a Notice of Termination (NOT)with the State to final out the project.
*Note the Land Resources Self Inspection Program Requirements.This program is separate from the NPDES
reporting and requires inspection and documentation after each phase of construction.These phases include:
Installation of perimeter erosion control measures, Clearing and Grubbing of existing ground cover,Completion
of any phase of grading of slopes or fills, Installation of storm drainage facilities, Completion of construction or
development, Establishment of permanent ground cover sufficient to restrain erosion and any Deviation from
the approved plan.
