Stormwater Permit Re -submittal for SW8021101 MOD
Dear Mary Jean:
This letter is in response to the Request for Additional Information letter dated September 12, 2006.
The following comments address the information requested:
1. We have verified the ownership of the property that is identified in the permit application for
each of the lots 1 through 14, as well as the adjacent properties. This information has been
added to Sheet C2 of the design plans. Ucq-+,�
2. We have included lot 5 on the deed restrictions and protective covenants. We have also
included lot 5 in the Stormwater Project Boundary, and are requesting this existing BUA be
exempt from stormwater controls. The tax records for this lot were previously provided as
documentation. The tax card shows the building was built in 1986, with building dimensions
drawn as 102' x 60' plus 50' x 60'. According to our client the additional impervious areas
were constructed at the same time, to serve the building.
3. Pond 2 orifice has been revised to a 1 %2" orifice to utilize readily available pipe size.
The calculations for all ponds have been revised to show the drawdown utilizing actual inside
diameter. A table showing the values used for these calculations has been added to the
calculation package. We have verified that the drawdown time is between the required 2 to 5
days for all ponds.
4. We have placed a note stating "All roof drains are to be directed to stormwater collection
system" on Sheet C2.
5. The plans have been revised to show the existing impervious area (BUA) in DA 4. The
applications and deed restrictions have also been revised to reflect this modification.
The drainage area to Pond 2 incorrectly stated an area designated as `common asphalt', at
this time it is only considered common area, and there is no existing BUA in this area. The
existing BUA on lot 4 has been revised.

Enclosures: Design Plans, Sheets C2, C3, C4, C6 and C7, revised October 2006, 2 copies
Revised Application, page 2 and supplemental Drainage Area sheet
Calculations, revised October 2006
Deed Restrictions, revised

Stormwater Project No. SW8 021101 MOD
North Brunswick Industrial Park, Brunswick County
Dear Mr. Dale;
The Wilmington Regional Office received a Stormwater Management Permit Application for North
Brunswick Industrial Park on August 31, 2006. A preliminary review of that information has determined
that the application is not complete. The following information is needed to continue the stormwater review:
Please verify the ownership of the property that is identified in this permit application for each of lots
numbered 1 through 14 and the adjacent properties. The stormwater permit issued on April 10, 2003
and associated plans identified one small existing building with paving on each of lots numbered 5
and 6 only. [re: East Coast erosion control plan , sheet 1, ECEC project no. 0518]. The plans
submitted with this application for modification, that were received by this office on August 31,
2006, reflect built -upon areas for buildings and paving for lots numbered 4 and 8 [in addition to the
BUA on lots 5 and 6]; and these built -upon areas have not been permitted on lots 4 and 8. Please
verify ownership for all lots on this property and adjacent. This property appears to be common
plan development, which require stormwater controls for the entire area.
Please be advised that only clearing, grading, and stormwater controls were permitted with the April
10, 2003 stormwater permit. The permittee must submit a modification and receive approval prior to
the construction of any built -upon surfaces, regardless of ownership or the amount of land
disturbance.
Please be advised that prior to any development and at least 30 days prior to the sale of any part of
this project, the permittee must notify DWQ and provide the legal entity name, contact name,
mailing address and telephone number of the party that will purchase the site, and the permittee must
initiate the transfer of this permit, or part thereof, to the purchasers -Te B e i 1 �CD�.O�J routs k
2. Include project area and built upon for lot 5 on the deed restrictions and protective covenants.
Although the built upon area was initiated in 1986, the project area and BUA must still be included
in the stormwater permit. If you are claiming exemption for stormwater controls for areas
developed prior to 1988 as stated on drawing C2 and project description, then provide documentation
reflecting development prior to 1988. All areas developed since 1988 require stormwater controls
and inclusion in the pond sizing calculations.
Verify orifice sizing for pond numbers 2 and 4. Use true inside diameter of pipe for sizing
calculations and readily available pipe sizes. For example, pipe is not readily available in 1-3/4 inch
diameter as specified for pond 2. Pipe is sold in 1 '/ inch or 2-inch diameter increments. Pond 4
using true inside diameter of 1.476 inch results in draw down time of 4 days. Consider using 2 inch
nominal, with an ID of 1.913 inch, will achieve a lower drawn down time. Recalculate and submit
revised plans and calculations.
4. Locate roof drains such that the runoff is directed to the pond. Document on plans.

5. Document on plans the location and dimensions for all existing built upon areas, including buildings,
walkways, street paving, etc... Drainage area [DA] to pond 4 reflects 90,590 SF on the application
section III. (6), whereas only 7000 SF is identified as existing BUA for each of the building and road
areas on plan no. C6. DA to pond 2 does not dimension the area designated as `common asphalt'.
Please note that this request for additional information is in.response to a preliminary review. The
requested information should be received by this Office prior to September 29, 2006, or the application will
be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee.
If you need additional time to submit the information, please mail or fax your request for a time
extension to the Division at the address and fax number at the bottom of this letter, to the attention of Mr.
Cameron Weaver — Express Permitting. The request must indicate the date by which you expect to submit
the required information. The Division is allowed 90 days from the receipt of a completed application to
issue the'permit.
The construction of any impervious surfaces, other than a construction entrance under an approved
Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action
pursuant to NCGS 143-215.6A.
Please reference the State assigned project number on all correspondence. Any original documents
that need to be revised have been sent to the engineer or agent. All original documents must be returned or
new originals must be provided. Copies are not acceptable. If you have any questions concerning this matter
please feel free to call me at [phone].

STORMWATER NARRATIVE
for
North Brunswick Industrial Park
Leland, Brunswick County, NC
DESCRIPTION
The project area is site is 23.90-acres located within North Brunswick Industrial Park on Division Drive
off of Old Fayetteville Road in Leland, North Carolina. The proposed development on the site is thirteen
(13) lots to be used for industrial purposes, with Lot #5 grandfathered as the building and parking area
were constructed in 1986. Construction is scheduled to begin as soon as all permits and approvals are
obtained.
STORMWATER MEASURES
The stormwater runoff from the site is estimated using the rational method. The stormwater will be
directed to yard and drop inlets through grading of the area as well as swales. The stormwater will then
be directed to four (4) separate stormwater ponds.
EROSION CONTROL MEASURES
The attached plans give the requirements for erosion control measures. Silt fence will be located along all
existing ditches/swales already on site. The silt fence will be installed prior to any land disturbing
activity. There will a total of three (3) Temporary Construction Entrances. The grading contractor and
the developer will provide the maintenance for the erosion control measures.
CONSTRUCTION SEQUENCE
The Contractor will install the silt fence and the construction entrances. The disturbed areas will be
seeded upon completion, and as soon as possible.

RE: Project Name: North Brunswick Industrial Park
Project 1D: Bruns-2003-117 22 2 2
County/Town/Street: Brunswick, Town Creek, Old Fayetteville Ro
River Basin: Cape Fear
Submitted By: East Coast Engineering, Co.; PA AUG 2 2006
Date Received by LQS: July 28, 2006
Plan Type: NEW
Dear Mr. Dale:
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. 113A-54.1)(b).
Please be advised that Title 15A NCAC 413.0118(a) requires that a copy of the approved
erosion control plan be on file at the job site. Also, you should consider this letter to give 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 thru 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 be aware that your project will be covered by the enclosed NPDES General
Storm water Permit NCGO1000 (Construction Activities). You should first become familiar with
all of the requirements for compliance with the enclosed general permit.
Please note that this approval is based in part on the accuracy of the information provided
in the Financial Responsibility Form, which you have 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.

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 413.0029.
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. Each sediment storage device must be
inspected after each storm event. Maintenance and/or clean out is necessary anytime the device
is at 50% capacity.
3. 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. 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.
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 agencies such as the Division of Water Quality's stormwater regulations, their
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.
5. 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 Quality,
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 DWQ, the Corps, or the EPA, it is the
responsibility of the developer to inform the Land Quality Section regional office so that an
AUG 3 1 2006

Page 4 of 4
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.
6. Any borrow material brought onto this site must be from a legally operated mine or other
approved source. A single use borrow site or an area to waste material is only permissible if it is
operated under the total control of the Financially Responsible person or firm who is developing
this site and has been separately permitted and incorporated as part of this plan meeting all the
requirements of NC General Statue 74-49(7)f.
7. This permit allows for a land disturbance, as called for on the application plan, not to exceed
13 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.
8. The construction detail for the proposed silt fence requires reinforcing wire and posts a
maximum of 8.0 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 6 feet apart.
9. Because the stormwater retention ponds are shown on the plan as the primary sedimentation and
erosion control devices on this project, it is necessary that the ponds and their collection systems
be installed before any other grading takes place on site. 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 ponds are fully functioning.
10. 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.
11. The North Carolina Sedimentation Pollution Control Act mandates a shortened time frame in
which to re-establish vegetative groundcover. Slopes (including cuts, fills, and ditch banks) left
exposed will, within 21 calendar days after completion of any phase of grading, be planted or
otherwise provided with groundcover sufficient to permanently restrain erosion.
12. If the spoil from the proposed ponds cannot be used to balance the cut and fill, a revised plan to
include stockpile areas (with a design detail and temporary erosion control ) must be submitted
to this office for review.

Leland, NC 28451
RE: Project Name: North Brunswick Industrial Park
Project ID: Bruns-2003-117
County: Brunswick, Town Creek, Old Fayetteville Road
River Basin: Cape Fear
Submitted By: East Coast Engineering, Co., PA
Date Received by LOS: July 28, 2006
Plan Type: MODIFIED
Dear Mr. Dale:
This office has received a soil erosion and sediment control plan for the project listed above which
was submitted as required by the North Carolina Sedimentation Pollution Control Act (G.S. 113A-57 (4)).
The Act requires that all persons disturbing an area of one or more acres of land must obtain approval
of a soil erosion control plan prior to the commencement of the land -disturbing activity (G.S. 113A-54(d) (4)).
The Act further states that this plan must be filed a minimum of 30 days prior to the activity and the approving
authority must approve or disapprove the submitted plan within 30 days of receipt. Failure of the approving
authority to approve or disapprove the submitted plan within the 30-day period will be deemed approval of the
plan.
Commencement or continuation of a land -disturbing activity under the jurisdiction of this Act prior to
the approval of an erosion and sediment control plan is a violation of the Act.
We have performed a preliminary review of your submitted plan and have determined that additional
information will be necessary before a final review can be completed. Enclosed is a checklist of items that
must be submitted before we can complete the review process. Failure to provide the additional information
may result in disapproval of your plan.
The approval of an erosion and sediment control plan is conditioned on the applicant's compliance
with Federal and State water quality laws, regulations and rules.
If you have questions please do not hesitate to contact this office. Your cooperation in this matter is
appreciated and we look forward to working with you on this project.
Sincerely,
Schuyler J. Snowdon

For the lots in question, there is an existing sewer system beside Lot 7. A
6" line will be installed to the existing system from each lot. The owner
has set aside an easement area for the service lines. None of those lots
will be connected to the sewer system just certified.
Mr. Dale leases the buildings. We are presently designing a stormwater
