Dear Mr. Carroll:
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 413 .0129.
As of April 1, 2019, all new construction activities are required to complete and submit an electronic Notice of
Intent (NOI) form requesting a Certificate of Coverage (COC) under the NCGO10000 Construction Stormwater
General Permit. This form MUST be submitted prior to the commencement of any land disturbing activity on
the above named project. The NOI form may be accessed at deq.nc.gov/NCGO1. Please direct questions about
the NOI form to Annette Lucas at [e-mail] or Paul Clark at [e-mail]. After
you submit a complete and correct NOI Form, a COC will be emailed to you within three business days.
Initially, DEMLR will not charge a fee for coverage under the NCGO1 permit. However, on or after May 1,
2019, a $100 fee will be charged annually. This fee is to be sent to the DEMLR Stormwater Central Office staff
in Raleigh.
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 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 insure
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, 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 insure 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. Please notify us if you plan to have a preconstruction conference.
Your cooperation is appreciated.
Sincerely,

MODIFICATIONS REQUIRED FOR APPROVAL
Project Name: Villages at Skybrook North Lots 425-431, 435-439, 476-483
Project ID: CABAR-2019-078
County: Cabanrus
1. The new NCGOI Construction stormwater permit requires Ground Stabilization and
Materials Handling and Self -Inspection, Recordkeeping and Reporting requirements on your
plans. The NCGO1 compliance plan sheets for these can be found at
https: l(Icq.nc.t,ov abotit/divisions/cner�w-mineral-land-resourcesiener(,v-niineral-land-
pennitsistorniwater-perm i is 'constructioni-s%\ .
2. If contiguous lots are graded such that one acre or more is disturbed, individual lot controls
will be insufficient, and surface dewatering is required in order to maintain compliance with
the NPDES general construction permit. This site is limited to individual lot disturbance. If
contiguous lot grading for lots totaling 1 acre or more is to take place, an approved plan is
required before grading takes place, with specific locations for surface dewatering,
specifications and calculations for surface dewatering. [N.C.G.S. 143-215.1 ]
Any off -site borrow and waste required for this project must come from a site with an
approved erosion control plan, a site regulated under the Mining Act of 1971, or a landfill
regulated by the Division of Solid Waste Management. Trash/debris from demolition
activities or generated by any activities on site must be disposed of at a facility regulated by
the Division of Solid Waste Management or per Division of Solid Waste Management or
Division of Water Resources rules and regulations. [15A NCAC 4B .0110]
4. The site, or portions of the site as applicable, are required to be stabilized after any period of
inactivity. Slopes steeper than 3:1, perimeter dikes, swales, and ditches must be stabilized
within 7 days. All other areas must be stabilized within 14 days. [N.C.G.S. 143-215.1 ]
Silt fence may not be placed such that portions of the lot are exposed to erosion. [ 15A NCAC
4B .0105]
6. All access to the lots must be through the construction entrances. Construction entrances
must be in place prior to lot disturbance. [15A NCAC 4B .0105]
7. All inlets collecting drainage or that might potentially be affected by the lot construction
shall have inlet protection. Inlet protection must be maintained until all areas draining to the
inlet are fully stabilized. [ 15A NCAC 4B .0105]
All measures, including stone drive, will be inspected after rain and at least weekly for
adequacy and needed maintenance. [N.C.G.S. 143-215.1 ]

9. All disturbed areas not built upon will be provided with permanent groundcover. [N.C.G.S.
113A-57(2)]
10. Effective October 1, 2010, persons responsible for land disturbing activities must inspect the
sediment and erosion control measures on a project after each phase of the project to make
sure that the approved erosion and sedimentation control plan is being followed. Self -
inspection reports are required. A sample self -inspection report, as well as details of the self -
inspection program, can be found on the Land Quality web site:
lit tl)::1pooal.ncdennorg'wehi-v%q: M S,'suiconstruction
Not every project will have all the possible phases, but a list of phases may include:
• Installation of perimeter erosion and sediment control measures.
• Clearing and grubbing of existing ground cover.
• Completion of any phase of grading that requires provision of stabilization.
• Installation of measures during any phase of the project.
0 Completion of construction or development.
• Quarterly inspections until the establishment of permanent ground cover is fully
established.
Please note these inspection requirements are in addition to NPDES inspection requirements.
[N.C.G.S. 113A-54.1(e)]
11. Additional measures may be necessary during the course of this project. [15A NCAC 4B
.0115]
