This is to verify that the off -site area which currently drains to our proposed water
quality pond behind the Wal-Mart Store is pervious area. The possibility of this area
being developed is limited due to the fact that the property does not have frontage
on any roads. Also, I believe there is a "no -build" easement on that portion of the
property as well.
Thank you for your prompt response to my questions.

Stormwater Project No. SW8 910502 Modification
Wal-Mart Expansion, Shallotte
Brunswick County
Dear Mr. Garcia:
The Wilmington Regional Office received previously requested information for the Stormwater
Management Permit Application for Wal-Mart Expansion, Shallotte on February 18, 1999. A preliminary
review of that information has determined that the application is not complete. The following information
is needed to continue the stormwater review:
A detail of the vegetated filter itself has not been added. A level spreader is not the same as
a vegetated filter. Please show a detailed cross-section of the proposed vegetated filter. Level
spreaders are mostly suited for use as a temporary Erosion Control device to disperse flow
from channels and ditches into sheet flow. They are not recommended for permanent use as
the flow spreader mechanism for a vegetated filter. Please see the enclosed detail.
The stormwater permit cannot be issued until the wetlands permit is issued. The proposed
pond is located in existing wetlands. Please forward a copy of that permit when issued to
complete the review of this project.
Please label the outlet structure in the pond.
The trash guard diameter has not been specified on the outlet structure detail. The only
diameter shown is for the 48" riser. Necessarily, the trash guard must be larger than 48" in
order to fit over the riser.
5. Please add the outlet structure detail for the existing pond. Since these plans will replace and
supersede those currently approved, all required details must be shown for the existng pond.
6. The data for the existing pond on the application indicates a .32 acre offsite area, but the
drainage area delineation on the grading plan does not show any offsite drainage areas. Please
clarify. If offsite drainage is indeed entering the existing pond, please include it in the
drainage area delineation and make any needed revisions to the acreage of the drainage area
and in the calculations to account for it. The regulations require that offsite runoff be
accounted for at the full buildout potential. Please provide information on the type of existing
impervious surfaces in the offsite area, and the potential for future development.

Stormwater Project No. SW8 910502 Modification
Please report the surface areas provided at the storage elevation for each pond. Based on the
average area method used, the volume provided at the storage elevation reported is not
sufficient to meet the minimum required, albeit by a small amount.
The required work of fixing the existing pond can be included in the scope of this
modification. There will be a permit condition to this effect. The store may not receive a
Certificate of Occupancy until the system is inspected and certified by a design professional.
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 June 5, 1999, or the application will be
returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee. The Division is allowed 90 days from the receipt of a completed application to issue the
permit.
The construction of any impervious surfaces associated with this project prior to receipt of the
stormwater permit is considered a violation of NCGS 143-215.1, and is subject to enforcement action.
If you have any questions concerning this matter please feel free to call me at [phone].

Wal-Mart Store #1767 Expansion
Shallotte, North Carolina
WATER QUALITY REPORT
The following is the stormwater management report for the expansion of the existing Wal-
Mart Store located at the intersection of NC Highway 130 and NC Highway 17 Business
in Shallotte, North Carolina. The existing store will be expanded from a +/-75,780 sf Wal-
Mart store to a +/-186,130 sf Wal-Mart SuperCenter. All of the development has been
accounted for in the stormwater calculations. The stormwater system will be a
combination of catch basins and pipes which will convey all runoff from this development
to the stormwater management (SWM) facilities.
The existing development currently has a water quality pond on site. The amount of
impervious area to this pond will be significantly reduced with the expansion. The only
modification to this facility will be reducing the size of the orifice for the release of the first
one (1 ") inch of rainfall. The proposed SWM facility is required to control the first one
0 ") inch of runoff from the site, and it has been sized to release the 100 year storm event
through the top of the riser. All runoff will be directed to the western portion of the site.
This SWM facility will also serve as a sediment basin during the construction phase.
Please also note that the pond will be a wet detention pond in order to satisfy the
requirements of the Division of Water Quality of NCDENR. Those calculations are also
included with this report. The first one 0 ") inch of rainfall volume will be released over a
period of between two and five days.

DRAINAGE AREAS:
In the pre -expansion condition, approximately 14.77 acres drains to the existing pond.
Out of this 14.77 acres, 9.54 acres is impervious. With the expansion of the existing Wal-
Mart Store, the impervious area directed to the existing pond is decreased to 5.05 acres.
The decrease is mainly due to the rerouting of the roof drainage from the building.
Currently the roof drainage is collected underground and piped to the pond. After the
expansion of the store, the roof will discharge all drainage to the rear of the building via
downspouts which release onto the pavement. The runoff will then enter the storm drain
system and flow to the forebay of the proposed pond in the rear of the store. The entire
drainage area to the existing pond will be decreased from 14.77 acres to 6.47 acres.
The drainage area to the proposed pond in the rear of the store is 11.08 acres. Of this
area, 7.73 acres is to be impervious. This results in an impervious area equal to 69:8% of
the drainage area. The corresponding calculations for water quality are included with this
report.
SWM FACILITY SIZING:
The proposed SWM facility will be constructed in the northwestern corner of the site to
the rear of the building. The facility will have a bottom elevation of 5.0 and the top of the
berm will be 15.0. The permanent pool elevation is 11.0 with side slopes of 6:1 for the
first twelve (12') feet. From this point, (elevation 9.0), the side slopes are to be 3:1 to
elevation 5.0. Also, the side slopes from elevation 11.0 to the top of the berm are to be
3:1.
The proposed pond is to have a forebay volume equal to +/-20% of the volume of the
permanent pool. The forebay shown on our plans has a volume equal to 20.0% of the
total permanent pool volume. The stormwater runoff from the site is directed to the
forebay through the storm drain system. The runoff discharges from the 36" storm drain
pipe accross the energy dissipater shown and into the forebay.
The calculations attached show that the first one (I ") inch of rainfall from the site will be
released from the proposed outlet structure over a period of 3.34 days. The calculations
also show that the 100 year storm runoff will pass through the top of the riser.

REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 910502 Modification
Wal-Mart #/1767
Brunswick County
Dear Mr. Garcia:
The Wilmington Regional Office received a modification to the Stormwater Management Permit
Application for Wal-Mart #t1767 on December 3, 1998. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
stormwater review:
1. Please see NCAC 2H.1003 (e) for information on who may sign the permit application. In the
case of a corporation, a principal executive officer of at least the level of vice president, or
his authorized representative must sign. Please either have the application resigned by an
appropriate party, or provide documentation that Mr. Doss is authorized to sign this
application.
2. Items m-t of the supplement form have not been initialled. Please have the applicant or agent
intial in the appropriate blanks.
3. Please seal the design calculations.
4. Please provide a supplement sheet for the existing pond which reflects the new design data-
ie., revised design storage elevation and orifice size. The requirements pertaining to the
forebay and vegetated shelf can be marked N/A, since this pond was permitted prior to these
items being required.
5. Please calculate the required SA/DA ratios, volumes, etc., for the existing and proposed
ponds based on the individual revised new drainage and impervious areas. You cannot
calculate a minimum required surface area based on the overall site, and all a portion of
the required area to each pond. Each pond's drainage area, impervious area; and SA/DA ratio
is calculated separately.

6. Based on #5 above, please provide a revised supplement sheet for the new pond, and provide
a detail section view of the existing pond which includes the proposed changes in storage
elevation and orifice size.
7. The orifice size must be based on the volume actually provided in the pond between the
specified permanent pool elevation and storage elevation. You have based yours on the
calculated minimum.. Additionally, the head used should be an average head, since the total
head will not be available as the pond drains down, and the flowrate will slow. Please revise
8. Please label the columns on the application as to which column belongs to what pond. You
may label the ponds 1 and 2, A and B, new and proposed or Moe and Orly (just joking).
9. Please specify standard stock sizes for the orifice. pipe. Finding a 2.2" D orifice may be a little
difficult and expensive to fabricate. My calculation indicates that a range of 2" $ to 2.5"f is
acceptable.
10. Please delineate the drainage area to each pond, including the offsite areas, on the plans.
11. Please delineate all jurisdictional wetlands, or note on the plans that none exist. Ponds may
not be located in wetlands.
11. Please provide the dimensions and radii of each side of the figure created by the permanent
pool.
12. Please add the vegetated filter detail to the plans for both ponds. Include the flow spreader
mechanism type, elevations, and type of grass to be planted. Also include calculations
indicating a non -erosive velocity for the 10 year storm.
13. Please indicate the diameter of the trash rack on the detail.
14. If the orifice is to be placed into the riser with no slope, ie., flat, please specify a trash guard
for the orifice. You may also elect to place the orifice at a negative slope, ie., the pond side
inlet 6" below the permanent pool elevation, with the outlet end into the riser at the permanent
pool elevation. This design eliminates the need for additional trash screens.
15. The outlet detail has a note that says to extend the trash rack below the weir. What weir is that
note referring to? No other outlets except the orifice are allowed between the permanent pool
and the storage elevation.
16. Please label and delineate the permanent pool and storage pool contours on the grading plan.

17. Please place typical dimensions for the parking lot on the site plan. I see where the spaces
have been dimensioned, but the aisle widths must also be included.
18. The existing pond has had compliance and maintenance problems in the past. None of the
letters sent from this Office to Wal-Mart concerning the inspection reports and required
maintenance actions has ever been responded to. The existing pond must have the sediment
removed and be brought back into compliance prior to issuing this permit modification.
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 March 3, 1999, or the application will be
returned as incomplete. The return of a project will necessitate resubmittal of all required items, including
the application fee. The Division is allowed 90 days from the receipt of a completed application to issue the
permit.
If you have any questions concerning this matter please feel free to call me at [phone].
