I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater described in
the application and other supporting data.
2. This stormwater system has been approved for the management of stormwater runoff as
described in Section 1.8 of this permit. The runoff from all built -upon area within the permitted
drainage areas of this project must be directed into the permitted stormwater control
measures. The stormwater control measures labeled Pond A and Pond B have been designed
to handle the runoff from 155,921 and 86,000 square feet of built -upon area, respectively.
3. The maximum built -upon area allowed for the entire project is 241,921 square feet.
4. The drainage areas will be limited to the amounts of built -upon area indicated in Sections 1.2
and 1.8 of this permit, and per approved plans. The built -upon area for future development
within the drainage area for Pond A is limited to 46,300 square feet. This permit does not
provide any allocation of built -upon area for future development within the drainage area for
Pond B.
5. A 50' wide vegetative buffer must be provided and maintained adjacent surface waters,
measured horizontally from and perpendicular to the normal pool of impounded structures, the
top of bank of both sides of streams and rivers and the mean high water line of tidal waters.
6. Vegetated filter strips are not required for these ponds as they have been designed for a 90%
total suspended solids removal efficiency.
7. All runoff being directed into wetlands shall flow into and through those wetlands at a non -
erosive velocity.

Wet Detention Pond .Maintenance Requirements i
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if
one is provided.
Important maintenance procedures:
Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the
basin should be watered twice weekly if needed, until the plants become established (commonly six weeks).
No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to
establish the plants on the vegetated shelf.
Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention
basin.
If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the
emergency drain should be minimized to the maximum extent practical.
- Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event
greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a
known set location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately.

WC'i%7 Enterprises is developing a proposed self -storage facility located on US 74/76 at the intersection of
Enterprise Drive, which is Leland Industrial Park or Windsor Commercial Park. It is further identified by
Brunswick County PIN #: 218809062699, Parcel ID 0280000842 (10.70+/- ac), and coordinates: Lat: 34' 15'
33.39"N, I-ong: 78' 4' 22.94" W. The site is adjoined by US 74/76 to the south, a Duke Energy substation
and shop to the west, Enterprise Drive to the east, and Trade Street to the North cleared property except the
east, which is residential use. A Duke Energy Transmission 70-ft ROW (Sutton Line 230Kv South) runs
across the property.
The current site consists of 0-1% sloped terrain with part woods. The existing soils on the site are
predominantly Leon fine sand (Lo) according to the Web Soil Survey of MRCS. According to the attached
USGS map, the site drains to Banton Branch, which is classified as C; SW in Cape Fear River Basin.
ASBUILT STORMWATER CONTROL MEASURES
Two wet retention ponds are being used to treat the 1.5-inch rainfall -runoff per NCDEQ State Stormwater
Coastal Rules and provide peak discharge control below pre -developed runoff for the 1-yr and 10-yr design
storms per the Brunswick County Stormwater Ordinance. The wet pond was calculated utilizing SCS TR-20
hydrograph routing simulations through use of I-lydroCAD modeling software. The treatment requirements
for the 1.5-inch rainfall runoff were calculated using the Simple Method Runoff Calculation and the 90°/, TSS
removal requirements of a wet detention pond as described in the NCDEQ Stormwater BM Manual.
Storm conveyance calculations have been performed utilizing the Rational Method for the I0-yr and I00-yr
design storms to check for flood control within the pipe system. The hydraulic grade line (HGL) calculations
were performed through the Carlson Drainage Software using HEC22 Energy -Loss Method. The published
Brunswick County ID1~ Tables have been used for the design storms.

NCDEQ Wet Retention Basin Requirements
Objective: Design a wet retention basin with the following characteristics: a permanent water pool depth between 3- and
6-Feet, a surface area that meets TSS removal requirements (values set by NCDEQ and Included here), a forebay that
is approximately 20% of the total pond volume, a temporary water pool sized to detain the initial 1.5 inch of rainfall runoff an
outlet device that drains the temporary water pool within 2-5 days, and a length -to -width ratio of approximately 3:1.

Leland, Brunswick County
Dear Ms, Hall:
On behalf of Bill Schoettelkotte and WCM Enterprises, LLC, we are responding to the above referenced
Request for Additional Information for Stormwater Permit SW8 160910 dated October 31, 2019 after the
changes were submitted August 12. Please find below our responses in bold bullets.
1. 15A NCAC 02H.1008(e)(4) effective September 1, 1995: The revised site plans propose a 3"
conduit to be installed along the pond bank to improve the flow path of the system and prevent
the pond from short circuiting. Please provide additional details of this proposed conduit
including invert elevations and the design proposed for the end cap / orifice area.
• Design Details added to Sheet ABA and AB-2.
2. 15A NCAC 02H.1042(2)(0: For Pond A, please confirm the following information:
a. The SA/DA ratio. The SA/DA ratio presented in the revised calculations differs from the
ratio presented in the revised supplement. Additionally, the SA/DA ratio presented in the
calculations for this 90% TSS removal pond with an average depth of 4.7 ft and an
impervious percent of 73% is not consistent with the SA/DA table in place when this
pond was permitted.
• We just rounded down to 4.5 and used 5.77. It can be 5.66 but it makes no
impact to the calculations as we are far exceeding the required SA. I think the
spreadsheet had a number in error of 5.49 SAIDA.
b. The surface area for this pond at an elevation of 55.0 ft presented in the stage -storage
tables. This surface area is smaller than the surface area presented at an elevation of 54.4
ft.
• The 54.5 elevation contour area should have been 20,183sf and not 21,542sf,
Calcs and supplements changed as well.
c. The surface area at the bottom of the vegetated shelf presented in the revised supplement.
The surface area presented in the supplement for the bottom of the vegetated shelf is the
surface area of the permanent pool,
• Supplement revised.
Please find revised documents and maps.

Gentlemen,
Attached is a pdf of the request for additional information for the subject project. There are just a few administrative
items that need to be addressed.
Also, since this is in the home stretch and I understand there is a need to transfer the permit after this
modification. Since this site is under an NOV and the new property owners have not submitted a plan of action to
resolve these items, the transfer cannot be accepted for review until these items are resolved, constructed, and the
following is submitted: a new certification covering the revisions to the pond and site, an 0&M signed by the new
owners, and a $505 transfer application fee.
Please let me know if you have any questions or concerns.

Dear Ms. Hall:
On behalf of Bill Schoettelkotte and WCM Enterprises, LLC, we are responding to the above referenced
Request for Additional Information for Stormwater Permit SW8 160910 dated July 11, 2019, This is also
in accordance with a written time extension until August 12tt, granted by your office. Please find below our
responses in bold bullets.
1. 15A NCAC 02H.1008(e)(4) effective September 1, 1995: The location of the outlet structure
for Pond A has been relocated adjacent to the forebay berm and inlet. The cover letter provided with
the modification package indicates that the pond "should not short circuit based on the 1.5" rainfall -
runoff staging of the temporarypool with a pipe flow entering the forebay deeper than the forebay top
and raising the pond level till it reaches the secondary overflow. " This statement describes the
hydraulics of the forebay and does not address the fact that the pond inlet and outlet structures, as -
built, allows the runoff to short circuit the pond. Please re-evaluate the pond design to avoid short
circuiting.
• Pond A's primary orifice has been extended further along the shelf to extend
the length of flow path. According to the 1995 rule above, "The inlet structure
must be designed to minimize turbulence using baffles or other appropriate
'design features and shall be located in a manner that avoids short circuiting in
the pond; This increases the flow path to 2:1.
2. 15A NCAC 02H.1042(2) and. 1042(3)(b): The revised application and calculations indicates that the
drainage area and built -upon area draining to Pond A has increased. Please note that the increased drainage
area and built -upon area are subject to the 2017 rules. Additionally, the revised calculations also include
Pond B with updated surface areas and volumes. Please provide revised supplements documenting these
changes. Also, please email the supplement forms to the email address provided below so that they can be
preserved electronically per the regulatory requirements.
• Pond A's drainage area and impervious area increased from the approved
pond; however the asbuilt condition can handle the increased surface areas
and volumes per the pre-2017 rules. Updated supplements have been emailed
to your email address.
3. 15A NCAC 02H. I 042(2)(f):
a. To support the temporary pool is designed to contain the minimum required storage volume,
please provide the surface area and provided storage volume at the temporary pool elevation in the
calculations, preferably in the stage -storage table.
b. and .1008(e)(3) effective September 1, 1995: When using Option 2 to calculate the average
depth of the pond, the area at the bottom of the pond is considered to only include the main pool.

depth of the pond.
c. Pond A was previously approved as with a 90% TSS removal efficiency. If this is not changing,
then based on the provided average depth and the percent of impervious surfaces, the SA/DA ratio
should be higher than the 4.57 presented in the calculations. Please ensure the 90% TSS removal
SA/DA table is being used to determine the SA/DA ratio for this pond.
• Temp. Pool Elevation of 55.50 is shown in the stage -storage table. Option 2
calculation has been updated. The entire stage -storage values have been
updated based on updated field survey. The SAIDA Ratio is re -calculated as
well.
4. 15A NCAC 02H. I 042(2)(g)(iv): Please provide additional contours and/or spot elevations along
the edges of the pavement and drainage areas to support the delineated drainage areas.
• DA Map updated and Site Plan shows grades too.
5. 15A NCAC 02H .1042(2)(g)(v): Section IV.10 of the application identifies 21,500 sf of other
BUA within the drainage area of Pond B. However, the site plans do not delineate any BUA other than the
storage buildings and the access drives. Please delineate and/or identify the other BUA on the revised site
plans.
• Site Plan Revised to include gravel area into Pond B and assign 40,000 sf into
the Other category instead of 21,500 + future sf.

At the time of the transfer, a correct address was 305 Colonial Dr. This address
is no longer on the secretary of state registration for WCM Enterprises as you
found out, and is now 2912 Hydrangea Place, Wilmington NC . Bill's email you
already have and phone number is 910-332-1593. Per Bill and WCM, you have
permission to write this on the State application or wherever is necessary.
Regardless, the new permitee as part of the transfer is LIP Mini Storage, LLC
and their address remains the same at 223 Greenville Ave. Bill S. is manager
for both entities.
Please find revised documents and maps.

Branch,
I'm not sure that extending the drawdown pipe towards the middle of the pond will be sufficient to demonstrate the
pond does not short circuit. However, we will take a look at whatever the selected solution ends up being along with
your justification in further detail when you submit the revised plans.
As for the extension request, I cannot grant an additional 30 days. The best I can do is grant another 15 days, however,
this extension will cut into the response time if a second request for additional information is needed. Please advise if
you would like an extension to August 12.
I'm not clear what you are asking when you refer to converting to the 2017 rules. The submittal package did not
indicate such a change was being requested. Please provide more information regarding this question.

I guess one solution to the short-circuiting issue, is to run the drawdown orifice pipe away from the box towards the
middle of the pond, right? Can you please also allow for an additional 30 days so its Aug 26, 2019? Also, you're saying
we cannot simply convert the calcs to the 2017 rules?

Subject: Request for Additional Information
Stormwater Project No. SW8 160910
Enterprise Drive Self -Storage
Brunswick County
Dear Mr. Schoettelkotte:
The Wilmington Regional Office received and accepted a modified State Stormwater Management Permit
Application for the subject project on April 29, 209. A preliminary in-depth review of that information
has determined that the application is not complete and that additional information is needed. To
continue the review, please provide the following additional information:
ry 1. 15A NCAC 02H.1.008(e)(4) effective September 1, 1995: The location of the outlet structure for
Pond A has been relocated adjacent to the forebay berm and inlet. The cover letter provided with
the modification package indicates that the pond "should not short circuit based on the 1.5 "
rainfall -runoff staging of the temporary pool with a pipe flow entering the forebay deeper than
the forebay top and raising the pond level till it reaches the secondary overflow. " This statement
describes the hydraulics of the forebay and does not address the fact that the pond inlet and outlet
structures, as -built, allows the runoff to short circuit the pond. Please re-evaluate the pond design
to avoid short circuiting.
t/ 15A NCAC 02H.1042(2) and .1042(3)(b): The revised application and calculations indicates that
the drainage area and built -upon area draining to Pond A has increased. Please note that the
increased drainage area and built -upon area are subject to the 2017 rules. Additionally, the
revised calculations also include Pond B with updated surface areas and volumes. Please provide
revised supplements documenting these changes. Also, please email the supplement forms to the
email address provided below so that they can be preserved electronically per the regulatory
requirements
3. 15A NCAC 02H.1042(2)(0:
�,a: To support the temporary pool is designed to contain the minimum required storage
volume, please provide the surface area and provided storage volume at the temporary
pool elevation in the calculations, preferably in the stage -storage table.
t/b. and .1008(e)(3) effective September 1, 1995: When using Option 2 to calculate the
average depth of the pond, the area at the bottom of the pond is considered to only
include the main pool. Please exclude the forebay from the bottom of the pond surface
area used to determine the average depth of the pond.
7 c. Pond A was previously approved as with a 90% TSS removal efficiency. If this is not
changing, then based on the provided average depth and the percent of impervious
surfaces, the SA/DA ratio should be higher than the 4.57 presented in the calculations.
Please ensure the 90% TSS removal SA/DA table is being used to determine the SA/DA
ratio for this pond.
t/4. 15A NCAC 02H.1042(2)(g)(iv): Please provide additional contours and/or spot elevations along
the edges of the pavement and drainage areas to support the delineated drainage areas.

Please remember to confirm that any revised information is presented consistently throughout the
application documents including calculations, supplements, narrative, and plans. Please also remember to
provide two hard copies of any updated documents per 15A NCAC 02H.1042(2).
The requested information should be received in this Office by July 26, 2019, or the application will be
returned as incomplete. If the project is returned and you wish to re -submit later, you will need to
resubmit all required items at that time, including the application fee.
If additional time is needed to submit the requested information, please email your extension request,
prior to the original due date, to the Division at the email address provided below. The extension request
must include a justification and a date of when the requested information will be submitted to the
Division, which shall be no later than 15 days past the original due date. Please remember that extension
requests delay the issuance of the final 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.

Dear Ms. Scott:
On behalf of William Schoettelkotte and WCM Enterprises, LLC, we are responding to the above
referenced Notice of Violation for Stormwater Permit SW8 160910 issued October 21, 2016.
There is a new landowner, LIP Mini Storage, LLC, therefore we have sent in the Application for Transfer
after the violations are resolved as part of this Modification. We have provided the revised project plans
and calculations. The pond changes were a result of NCDOT not allowing discharge to US 74-76;
therefore, the only outlet to the proposed pond was back towards the rear of the site along a side ditch.
Both ponds discharge into the side ditch which travels to Trade Street's drainage and the overall
Industrial Park. Pond A should not short circuit based on the 1.5" rainfall -runoff staging of the temporary
pool with a pipe flow entering the forebay deeper than the forebay top and raising the pond level till it
reaches the secondary overflow.
Please find attached stormwater modification and permit transfer along with Asbuilt Drawings of the
Ponds and Grading Plan, and updated Site Plan and Drainage Area Map.
