MESSAGE:
Michael:
The Division received a modified stormwater management permit application for the
subject project on December 19, 2003. The application is incomplete. Please provide
the following items by close of business on Thursday, March 4, 2004, to continue the
review:
1. The revised plans will replace those previously permitted, therefore please
add all of the previously permitted pondlforebay section and outlet structure
details to the plans.
2. Please add existing and proposed contours to the revised plans. The
previously approved plans contained many more spot elevations.
3. The original permit was written to cover 61,648 sq. ft. of built -upon area so
technically, there is no change in the amount that was permitted, just the
layout. However, because the ownership is also changing, I am going to
reissue the permit to the new owners.
4. The pond has not been certified. I am unable to issue a modification until the
Designer's Certification is provided.

Mr. Phil Tripp, P.E.

Wilmington, NC 28401
Subject: ACKNOWLEDGEMENT OF RECEIPT AND
REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 970320
Eastern Aluminum
New Hanover County
Dear Mr. Tripp:
The Wilmington Regional Office received a Stormwater Management Permit Application for Eastern
Aluminum on March 21, 1997. 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 check the location of the numbers on the application form. I believe the project area
and built -upon area are reversed.
2. Please locate and label the .75 acres of existing impervious area.
3. Please check the correlation of the forebay section elevations to the plan contours. The bottom
of the forebay on the detail is 17, but the plan contours indicate 15. The 17 contour is
incorrectly drawn in the pond; it should be 6' away from the 18, and there are two 18
contours shown.
4. Provide calculations indicating that the forebay can hold 20 % of the first V volume.
5. Delineate all wetlands on site, or note on the plans that none exist.
6. Is there any off -site drainage? Please add a note to the plans indicating that either there is no
off -site drainage entering this system, or that there is off -site drainage, and provide a
delineation of the area.

7. Please locate the 13,508 ft2 of stone area shown in the calculations.
8. Please check your calculation of the surface area provided at 19.2. I get about 6,700 ft2 as
opposed to your 6,171 W.
9. When rounding orifice sizes using the 2 day flowrate, please round down, not up. The 1.5"
orifice you have specified is too large. If there is any doubt, please calculate sizes for both
the 2 and 5 day drawdown and pick a size in between.
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 May 1, 1997, 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 have any questions concerning this matter please feel free to call me at [phone].
Sincerely,
Ms. Linda Lewis
