REQUEST FOR ADDITIONAL INFORMATION
Stormwater Project No. SW8 980701 Modification
Triple T Parts and Equipment
New Hanover County
Dear Mr. Tripp:
The Wilmington Regional Office received a modification to the Stormwater Management Permit
Application for Triple T Parts and Equipment on March 2, 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:
1. Please provide the dimensions for the parking areas, stone areas and buildings, both existing
and proposed.
2. Please show how runoff from the existing site is directed into the pond, especially along the
southeast and southwest perimeter. Provide all centerlines, elevations, grading, etc. You have
based the pond design on both existing and proposed areas, therefore, all runoff from both
those areas must drain into the pond. If some or all of the existing impervious surfaces will
not be directed into the pond, please delineate a drainage area and recalculate the pond based
on the new DA.
3. The south edge of the site appears to sheet flow into the pond, without going through the
forebay. Please provide a swale along the edge of the pond to direct runoff into the forebay
area and avoid short-circuiting the pond. Provide all centerlines, elevations, grading, etc., to
indicate how runoff is collected.
4. The supplement form you provided was discontinued in August, 1998. Please fill in the most
current form, have Mr. Matt sign it, and return it to me.
5. Please provide a vicinity map in accordance with the requirements of NCAC 2H.1003 (g)(3).

----------------------------------------------
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 20, 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].

Triple T Parts and Equipment
Stormwater Project No. SW8 980701 Modification
New Hanover County
Dear Mr. Matt:
On December 11, 1998, the Wilmington Regional Office received a copy of the modification for Triple T Parts
and Equipment. The North Carolina Administrative Code requires any project that must receive either a Sedimentation
and Erosion Control Plan permit and/or a CAMA major permit, or any modification to those permits, to apply for
and receive a Stormwater Management Permit by the Division of Water Quality. Any construction on the subject site,
prior to receipt of the required permit, will constitute a violation of 15A NCAC 2H.1000 and may result in appropriate
enforcement action by this Office.
Either a Stormwater Permit Application Package including 2 sets of plans., completed application form, fee,
and supporting documentation, or a written response regarding the status of this project and the expected submittal
date must be received in this Office no later than March 4, 1999. Failure to respond to this request may result in the
initiation of enforcement action, and construction may experience a subsequent delay. Please reference the Project
Number above on all correspondence. If you have any questions, please call me at (910)-395-3900.
Sincerely,
