Subject: Stormwater Permit No. SW3080401
Poplin Elementary School (New "L" School Site on Poplin Road)
High Density Commercial Wet Detention Project - Modification
Union County
vi,
Dear Mr. Hughes:
The Stormwater Permitting Unit received a complete Stormwater Management Permit Application for a
request -to modify the permit for Poplin Elementary School on July 26, 2012 to add additional BUA to the
wet detention basin. Staff review of the plans and specifications has determined that the project, as
proposed, will comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000 and Session
Law 2006-246. We are forwarding Permit No. SW3080401, dated August 1, 2012, for the construction,
operation and maintenance of the subject project and the stormwater BMPs.
This permit shall be effective from the date of issuance until May 15, 2018, and shall be subject to the
conditions and limitations as specified therein. Please pay special attention to the Operation and
Maintenance requirements in this permit. Failure to establish an adequate system for inspection and
maintenance of the stormwater management system will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to
request an adjudicatory hearing upon written request within thirty (30) days following receipt of this permit.
This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina
General Statutes, and filed with the Office of Administrative Hearings, P.O. Drawer 27447, Raleigh, INC
27611-7447. Unless such demands are made this permit shall be final and binding.
This project will be kept on file at the Mooresville Regional Office. If you have any questions, or need
additional information concerning this matter, please contact Brian Lowther at [phone]; or
[e-mail].
Sincerely,
fin- Charles Wakild, P.E.

calculate overall percent built upon area (BI.IA). Nou-coastal zi7etlands landward of the NHW (or MHW) lute tttay
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 22.8 %
9. How many drainage areas does the project have?1 (For high density, count I for each proposed engineered
stormzoater BMP. For law density and other projects, use I for file whole property area)
