ATTN: Jason Byham, Division President
1505 King Street Ext., Suite 100
Charleston, SC 29405
RE: Project Name: Brunswick Plantation — Beaufort, Smithfield, and Hamptons Lots
Acres Approved: 35.54
Project ID: BRL NS-2021-011
County: Brunswick
City: Calabash
Address: South Middleton Drive NW
River Basin: Lumber
Stream Classification: Other
Submitted By: Matthew Savoie, Path Light Consulting, Inc.
Date Received by LQS: April 10, 2023(Revised)
Plan Type: Residential
Dear Mr. Byham:
This office has reviewed the subject erosion and sedimentation control plan and hereby issues this Letter
of Approval with Modifications and Performance Reservations. A list of the modifications and
reservations is attached. 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. Should the
plan not perform adequately, a revised plan will be required (G.S. I I3A-54.1)(b).
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.gov1NCG01. 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 NCGO 1 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 12 months.
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 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 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. This permit allows for a land -disturbance, as called for on the
application plan, not to exceed the approved acres. Exceeding the acreage will be a violation of this permit
and would require a revised plan and additional application fee. 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,
Rhonda Hall

APPROVAL COMMENTS AND CONDITIONS
Project Name: Brunswick Plantation — Beaufort, Smithfield, and Hamptons Lots
Project ID: BRUNS-2021-011
County: Brunswick
1. 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.
2. The developer is responsible for the control of sediment on -site. If the approved erosion and sedimentation
control measures prove insufficient, the developer must take those additional steps necessary to stop
sediment from leaving this site (NCGS 113A-57(3)). Each sediment storage device must be inspected
after each storm event (NCGS 113A-54.1(e)). Maintenance and/or clean out is necessary anytime the
device is at 50% capacity. All sediment storage measures will remain on site and functional until all
grading and final landscaping of the project is complete (15A NCAC 04B .0113).
Any and all existing ditches on this project site are assumed to be left undisturbed by the proposed
development unless otherwise noted. The removal of vegetation within any existing ditch or channel is
prohibited unless the ditch or channel is to be regarded with side slopes of 2 horizontal to 1 vertical or less
steep (15A NCAC 04B .0124 (d)). Bank slopes may be mowed, but stripping of vegetation is considered
new earth work and is subject to the same erosion control requirements as new ditches (NCGS 113A-
52(6)).
4. The developer is responsible for obtaining any and all permits and approvals necessary for the development
of this project prior to the commencement of this land disturbing activity. This could include our agency's
Stormwater regulations and the Division of Water Resources' enforcement requirements within Section
401 of the Clean Water Act, the U.S. Army Corps of Engineers' jurisdiction of Section 404 of the Clean
Water Act, the Division of Coastal Management's CAMA requirements, the Division of Solid Waste
Management's landfill regulations, the Environmental Protection Agency and/or The U.S. Army Corps of
Engineers jurisdiction of the Clean Water Act, local County or Municipalities' ordinances, or others that
may be required. This approval cannot supersede any other permit or approval; however, in the case of a
Cease and Desist Order from the Corps of Engineers, that Order would only apply to wetland areas. All
highland would still have to be in compliance with the N.C. Sedimentation Pollution Control Act.
If any area on site falls within the jurisdiction of Section 401 or 404 of the Clean Water Act, the developer
is responsible for compliance with the requirements of the Division of Water Resources (DWR), the Corps
of Engineers and the Environmental Protection Agency (EPA) respectively. Any erosion control measures
that fall within jurisdictional wetland areas must be approved by the aforementioned agencies prior to
installation. The Land Quality Section must be notified of a relocation of the measures in question to the
transition point between the wetlands and the uplands to assure that the migration of sediment will not
occur. If that relocation presents a problem or contradicts any requirements of either DWR, the Corps, or
the EPA, it is the responsibility of the developer to inform the Land Quality Section regional office so that
an adequate contingency plan can be made to assure sufficient erosion control remains on site. Failure to
do so will be considered a violation of this approval (NCGS 113A-54.I(b)).

6. Any borrow material brought onto this site must be from a legally operated mine or other approved source.
Any soil waste that leaves this site can be transported to a permitted mine or separately permitted
construction sites without additional permits under NCGS 74-49(7)(d). Disposal at any other location
would have to be 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 4.48 additional
acres for a total of 35.54 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.I(b)).
8. The plan includes a very specific phasing schedule. If it proves impractical to follow the proposed phasing
schedule, a revised plan will be required.
9. 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).
10. 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 (NCGO 10000). 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 (1 13A-54. I (b)).
11. 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.I(b)).
12. As a condition of the NPDES General Stormwater Permit (NCGO 10000), the financially responsible parry
shall comply with the NCGOI Ground Stabilization And Materials Handling requirements that became
effective April 1, 2019. The NCGO1 Ground Stabilization And Materials Handling standard detail can be
printed from the deq.nc.gov/NCGO1 website.
13. As a condition of the NPDES General Stormwater Permit (NCGO 10000), the financially responsible parry
shall comply with the NCGO1 Self -Inspection, Recordkeeping and Reporting requirements that became
effective April 1, 2019. The NCGO1 Self -Inspection, Recordkeeping and Reporting standard detail can be
printed from the deq.nc.gov/NCGOI website.
14. As a part of routine monitoring of the approved land -disturbing activity, the financially responsible parry
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).

SEED BED PREPARATION:
LIMING- Apply lime according to soil test recommendations. If the pH (acidity) of the soil is not known, an application of ground agricultural limestone atthe rate of 1 to 1 2tonslacre on
coarse -textured soils and 2-3 tons/acre on fine -textured soils is usually sufficient. Apply limestone uniformly and incorporate into the top 4-6 inches of soil, Soils with a pH of 6 or
higher need not be limed-
FERTILIZER- Base application rates on soil tests When these are not possible, apply a 10-10-10 grade fertilizer at 700-1,000 Iblacre Both fertilizer and lime should be incorporated
into the to 4-6 inches of soil. If a hydraulic seeder is used do not mix seed and fertilizer more than 30 minutes before application.

2. A North Carolina Department of Agriculture soils test (or equal) is highly recommended to be obtained for all areas to be seeded, sprigged, sodded or planted.
3- Use a seeding mix that will produce fast growing nurse crops and includes non-invasive species that will eventually provide a permanent greundcover Soil blankets may be used
in lieu of nurse crops. Mat, tack or crimp mulch, as needed to stabilize seeded areas until root establishment, Mulch must be applied uniformly over the soil with a cover density
of at least 80%.
4. Ground cover shall be maintained until permanent vegetation is established and stable against accelerated erosion.

Construction:
1. Construct the sediment barrier of standard strength or extra strength
synthetic filter fabrics.
2. Ensure that the height ofthe sediment fence does not exceed 24
inches above the ground. (Higher fences may impound volumes of
water sufficient to cause failure of the structure.)
3. Construct the filter fabric from a continuous roll cut to the length ofthe
barrier to avoid joints. When joints are necessary, securely fasten the
filter cloth only at a support post with 4 feet minimum overlap to the
next post.
4. Support standard strength filter fabric by wire mesh fastened securely
to the upslope side of the posts. Extend the wire mesh support to the
bottom of the trench. Fasten the wire reinforcement, then fabric on the
upslope side ofthe fence post. Wire or plastic zip ties should have a
minimum 50 pound tensile strength.
5. When a wire mesh support fence is used, space posts a maximum of
8 feet apart. Supports should be driven securely into the ground a
minimum of 24 inches.
G. Extra strength filter fabric with 6 feet post spacing does not require
wire mesh support fence. Securely fasten the filter fabric directly to
posts. Wire or plastic zip ties should have a minimum of 50 pound
tensile strength.
7. Excavate the trench approximately 4 inches wide and 8 inches deep
along the proposed line ofthe posts and upslope from the barrier.
8. Place 12 inches of fabric along the bottom and side ofthe trench.
9. Backfill the trench with soil placed over the filter fabric and compact.
Thorough compaction of the backfill is critical to silt fence
performance.
10. Do not attach filter fabric to existing trees.
Maintenance:
1. Inspect sediment fences at least once a week and after each 1 inch
rainfall. Make any required repairs immediately.
2. Should the fabric of a sediment fence collapse, tear, decompose, or
become ineffective, replace it promptly.
3. Remove sediment deposits as necessary to provide adequate storage
volume for the next rain and reduce pressure on the fence. Take care
to avoid undermining the fence during cleanout.

techniques in the table below:
Temporary Stabilization
• Temporary grass seed covered with straw or
other mulches and tackifiers
e Hydrose'eding
• Rolled erosion control products with or
without temporary grass seed
• Appropriately applied straw or other VIL11ch
• Plastic sheeting
Permanent Stabilization
* Permanent grass seed covered with straw or
other mulches and tackifiers
_ Geotextille fabrics such as permanent soil

2. Locate paint washouts at least 50 feet away from storm drain inlets and surface
waters unless no other alternatives are reasonably available.
3. Contain liquid wastes in a controlled area.
4. Containment must be labeled, sized and placed appropriately for the needs of site.
5. Prevent the discharge of soaps, solvents, detergents and other liquid wastes from
construction sites.
PORTABLE TOILETS
1. Install portable toilets on level ground, at least 50 feet away from storm drains,
streams or wetlands unless there is no alternative reasonably available. If 50 foot
offset is not attainable, provide relocation of portable toilet behind silt fence or place
on a gravel pad and surround with sand bags.
2. Provide staking or anchoring of portable toilets during periods of high winds or in high
foot traffic areas.
3. Monitor portable toilets for leaking and properly dispose of any leaked material.
Utilize a licensed sanitary waste hauler to remove leaking portable toilets and replace
with properly operating unit.
EARTHEN STOCKPILE MANAGEMENT
1. Show stockpile locations on plans. Locate earthen -material stockpile areas at least
50 feet away from storm drain inlets, sediment basins, perimeter sediment controls
and surface waters unless it can be shown no other alternatives are reasonably
available.
2. Protect stockpile with silt fence installed along toe of slope with a minimum offset of
five feet from the toe of stockpile.
3. Provide stable stone access point when feasible.
4. Stabilize stockpile within the timeframes provided on this sheet and in accordance
with the approved plan and any additional requirements. Soil stabilization is defined
as vegetative, physical or chemical coverage techniques that will restrain accelerated
erosion on disturbed soils for temporary or permanent control needs.
