Dear Mr. Goto:
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/NCGO1. Please direct questions about
the eNOI form to the Stoiuiwater 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

1. The approved E&SC plan as well as any approved deviation.
2. The NCGO1 permit and the COC, once it is received.
3. Records of inspections made during the previous 30 days.
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. All necessary easements and access agreements must be obtained and be current prior to starting
work. All potentially affected property owners must be notified prior to utility construction even
though the activity is covered under an easement or occurs within a right-of-way [G.S. 113A-
54.1(al)].
2. The plans include limits of disturbance (LOD) at some different locations without any measure
controls. It appears that this LOD will be a secondary access road during the construction However, If
the intent is to use those roads as a secondary access road,the applicant should update the plans to
reflect all the erosion and sediment controls devices that will be used along these roads. Additionally,
the plans will need to be revised to maintain the buffer zone of undisturbed vegetation when working
adjacent to any watercourse or any wetland as shown on sheet P4.
3. Provide details for the construction matting that is shown on sheet P5.
4. Provide inlet protection for all existing and proposed storm inlets. Clearly show that on your plans at
the existing culverts Refer to Section 6.5 of the NC Erosion and Sediment Control Planning and
Design Manual. Inlet protection must remain in place within the work area until all areas of the
project are stabilized. [15A NCAC 4B .0106(5)]
5. Additional measures may be required- The applicant is responsible for the control of sediment on-site. If
the approved erosion and sedimentation control measures prove insufficient, the applicant must take
those additional steps necessary to stop sediment from leaving this site. [15A NCAC 4B .0115]
6. This letter constitutes approval with modifications. For inspection purposes, two copies of revised plans
reflecting these modifications must be delivered to this office by October 30n, or two weeks prior to the
beginning of work, whichever date is earlier. [15A NCAC 4B .0107(c)]

Fact Sheet on the New NCGOI Permit DEQ

April 2019 G =Y l
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 NCG01 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 [e-mail] or(919)707-3639.
Organizational Updates Acronyms to Know
The new permit: COC: Certificate of Coverage, proof of coverage under an NCGO1 permit

Plans and organizes them with federal E&SC: Erosion &Sedimentation Control
construction activity requirements; e-NOI: Notice of Intent,application form for the NCGO1 permit
• Is clearly organized by topic;and e-NOT: Notice of Termination,form for closing out the NCGO1 permit
• Has less text and more tables. SWPPP: Stormwater Pollution Prevention Plan, required by the NCGO1
Technical Updates
The new permit:
• Requires that the E&SC Plan meet
SWPPP requirements(p.2);
• Provides a list of items that must be
included in the SWPPP,such as the1,
