Subject: Stormwater Permit No. SW3080401
Poplin Elementary School (New "L" School Site on Poplin Road)
High Density Commercial Wet Detention Project - Modification
Union County
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, NC
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,
Originally signed by Robert Patterson

I am writing in response to a letter from you to Don Hughes dated 10/6/2010. Your letter
addressed several concerns you had about the construction and maintenance of the wet pond at
Poplin Elementary School. After review of your letter we met on site along with your staff and
UCPS Operations staff.
Based on the input that you and your staff gave us at this visit I offer the following response to
your concerns. Please note the format is redacted from your letter, however the permit number
you reference is not correct. The Stormwater Management Permit number issued for Poplin
Elementary School is SW3080401 not SWO80101.
I. DWQ observed the Stormwater Control Structure and Access Easement and Agreement is in
draft Form. I have not been able to locate this agreement, however, since this is probably a
work product for the recorded access easement I am enclosing a copy of the survey with the
easement detailed. The attached survey prepared by Lawrence Associates, P.A. indicates the
easement as well as all signatures required for recordation. The easement has been recorded
with t{te Union County Register of Deeds.
2. DWQ observed that all vegetative matter as identified on the site drawing was not present at
the time of the site visit. This is a violation of Permit Number SWO80101 II Schedule of
Compliance Condition 1. (Page 2 of 4), Condition 6. Absence of vegetative matter was observed
during our site visit. We are proposing to restore this vegetative shelf as outlines in the
attached Plan ofAction.
Growing Possibilities....

3. DWQ observed the operation and maintenance at the site is minimal at this time this is a
violation of Permit Number SW080101 11. Schedule of Compliance Condition 3. (Page 2 of 4).
This school site does receive regularly scheduled maintenance. Periodically scheduler) BMP
measures will be employed in maintenance of the wet pond from this point forward
4. Schedule of Compliance Condition 4. (Page 2 of 4) of Stormwater Permit SW080101 requires
that the permittee shall provide the operation and maintenance records that include all
requirements for recordkeeping of the project necessary to operate the storm water controls at
optimum efficiency and maintain compliance with the permit. Recordkeeping for BMP will be
maintained from this point forward This recordkeeping will be formatted to conform to the
BMP schedule listed under" Operation and Maintenance "on sheet C-6 of the documents
submitted for the approved permit.
5.Title 15A NCAC 21-1 .1008 6) requires that upon completion of construction, the designer for
the type of stormwater system installed must certify that the system was inspected during
construction, was constructed in substantial conformity with plans and specifications approved
by DWQ, and complies with the requirements of this Section. As of the date of this letter, DWQ
has not received this certification. Refer to the permit dated March 7, 2008 on page 2 of 4 Item 6
for a list of constructed facilities. A storm water as- built Certification Package, as well as
Designer's Certification Letter, was sent to NCDENR- Mooresville, Surface Water Protection
on 71112009. I have attached another copy for your reference which indicates that the wet
pond was "inspected during construction, was constructed in substantial conformity with
plans and specifications approved by DWQ, and complies with the requirements of this
Section'
You closed your letter with a general summary of items which needed to be included in our
response. Please see the following:
1. Provide a plan and schedule for rehabilitation for the perimeter plantings of the pond(s). A
Plan of Action is attached which addresses the restoration of the vegetative shelf.
2. Please provide a final version of the Stormwater Control Structure and Access Easement and
Agreement. See response to preceding Item # I .
3. Provide examples of updated field documents and recordkeeping that you will use to insure
that the permit conditions are being met. The format for BMP recordkeeping will conform to
the Operations and Maintenance Schedule listed in item# 4. These records will be kept for site
visits performed at one month, 3 months and 6 month intervals.
4. Provide details demonstrating that the system was inspected during construction, was
constructed in substantial conformity with plans and specifications approved by DWQ, and
complies with the requirements of this Section. Provide details of as -built changes and needed
corrective actions. Deficiencies were noted at the time of the inspection so any prior submitted
certification and evaluation of the site is considered incorrect. Attached is a copy of the (a.)

Subject: Request for Additional Information
Stormwater Project No. SW3080401
New "L" School Site on Poplin Road
Union County
Dear Mr. Hughes:
The Division of Water Quality Qpritral Office received a Stormwater Management Permit
Application for the subject project on April 30, 2008. A preliminary review of that information
has determined that the application is not complete. The following information is needed to
continue the stormwater review:
DWQ requires a minimum 10-foot wide vegetated shelf be installed around the
perimeter of the Wet Detention Basin. The inside edge of the shelf shall be 6" below
the permanent (normal) pool elevation; the outside edge of the shelf shall be 6" above
the permanent (normal) pool elevation. Details on sheet C-6 indicate the outside edge
and normal pool elevation are the both at 626.0 feet. Wet Detension Basin
Supplemeet indicates that the Bottom Shelf elevation (625.0 feet) is one foot below
the SHWT and the permanent pool elevations (626.0 feet) and the top shelf (626.0) is
a foot above the permanent pool. Please resubmit two sets (Sheets sheet C-5, C-6 and
C-7) sealed, signed & dated layout & finish grading plans with appropriate details
and the corrected Wet Detention Basin Supplement Form.
2. Project does not provide stormwater treatment for added impervious surface for the
proposed improvement to Poplin Road.
3. Please verify that the local government does not require more stringent
stormwater controls.
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 13, 2008, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee.

Re: Stormwater Project No. SW3080401
New "L" School Site on Poplin Road
Union County
Dear Mr. Randall:
have made the following revisions to the water quality measures for an approval to the site for
construction:
1. I have revised the permanent pond elevation to 625.5 to the middle of the vegetated
shelf as noted. I have revised the calculations as well as the pond level on the grading
C-5, detail sheet for the BMP C-6 and road improvements sheet C-7 as requested. I
have also revised the supplement form with the new pond elevation and SHWT info.
Please find two copies of these items.
2. 1 have added a section of how I am handling water quality for the areas which drain into
the roadside ditches per our phone conversion with calculations and ditch sections to
handle the flow for water quality to get a total of 35% TSS removal. Sheet C-7 has hatch
on the large section of existing pavement which is an overlayment of asphalt, but it was
already paved. I only have a small 3 to 5' wide section that will be new impervious area.
This is noted in the calculation sections near the back of the calculation books behind
the wet pond design and before the soil report. I have also noted some information
about the impervious area in the narrative after wet pond design chart.
3. Union County only notes that they follow the State BMP manual for water quality and
require a minimum of release at the 1 and 10 year pre -developed rates. We are also
noting the release rate of the 50 and 100 year storms. These are not required to be
detention, but to be released.
If there are additional questions about the information, please call me. We appreciate the fast
service on the original review and request that if possible to get a quick return on the second
review to get the contractor started as soon as possible for a 2009 fall opening of the school.
Sincerely,
Y,,CV Archifecfs, PA

NARRATIVE
GENERAL,
The Poplin Grove Elementary School (Formerly `L' School, SW3080401) is located on
Poplin Road in Indian Trail, Union County, NC. The site is situated in the northwest
portion of the county in a low density area zoned R-3. Drainage is to North Fork
Crooked Creek, a class C water body that is part of the Yadkin River Basin. Soils on site
consist of BaB, CmB and ScA, with a hydraulic group classification of C.
The existing school complex, consisting of academic buildings, parking, sidewalks and
other features include 6.71 acres of impervious area. Prior to original construction in
2008, an existing pond was modified and permitted to treat the full 6.71 acres if
impervious area as a wet pond BMP. This BMP still serves the site and has additional
treatment capacity The school was originally permitted as a high density area containing
6.71 acres of impervious area on a 30 acre site. Drainage to the BMP was primarily
conveyed by a piped storm drainage system.
The proposed improvements involved with this modification include the addition of an
outdoor basketball court. The court will increase impervious area by 6,000 sf. The court
will be placed immediately outside of the existing drainage basin for the BMP, as
delineated by parking lot curb and gutter/ drainage features. A small storm drain network
will be added to collect runoff from the court directing it to the existing storm drain and
BMP for treatment. This permit modification involves updating the permit to account for
the increase in impervious area and drainage area associated with the new court. The
existing excess capacity of the BMP will handle the increase in areas. No physical
modifications to the existing BMP will be required.
BMP PERMIT MODIFICATION
This permit modification involves updating the permit forms to account for the increase
in impervious and drainage areas associated with the new court. The existing BMP
possesses adequate excess capacity to handle the additional areas. No physical
modifications to the existing BMP will be required. A summary of modifications include
the following:
• Increase of BMP drainage area from 1592 ac to 16.21 ac.
• Increase of site impervious area from 6.71 ac to 6.85 ac.
• Calculations providing verification of adequate capacity of existing BMP for
proposed improvements.
