Hatteras Satellite Office

Dear Mr. Outten:
WaV-zo
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7060712 for a stormwater treatment system consisting of three
infiltration basins serving the Hatteras Satellite Office located at 50346 NC Hwy 12 in
Frisco, NC expires on April 9, 2021. This is a reminder that permit renewal applications
are due 180 days prior to expiration. We do not have a record of receiving a renewal
application.
Please submit a completed permit renewal application along with a $505.00 fee for
permit renewal. Permit application forms for renewal can be found on our website at:
https://cleq.nc.Eov/about/divisions/enemy-mineral-land-resources/enema-minerakland-
rules/stormwater-pro gram/post-co nstruction. North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application form. You can request a copy by e-mailing me at roger.thorpe(a)ncdenr.gov.

Dear Mr. Wheeler:
Alan W. Klimek P.E. Director
Division of Water Quality
This office received a revised stormwater package for the subject project on November 29, 2006.
A preliminary review of the plans and specifications has been completed. Before a stomrwater permit can
be issued, the following items must be addressed:
1) The revised plans, along with more complete details of the drainage basins, show that not all
built -upon areas are captured and treated in the proposed infiltration basins. For high density
type projects, the stormwater rules require that all impervious surfaces be captured and
treated before leaving the site.
2) The revised soils report, along with site specific information regarding soil and water table
conditions, indicates less than 12-inches of separation between the bottom of basin no. 2
and the seasonal high water table (SHWT). The stormwater rules require 2-feet of separation
for infiltration systems; however, on a case -by -case basis, this office has permitted a few
projects where only 1-foot of separation was attainable. To my knowledge, the Division has
not issued stormwater permits for infiltration systems with less than 1-foot of separation. I
suggest that you have your consultants redesign the project to make sure that all proposed
infiltration systems for this site provide at least 12-24 inches of separation from the SHWT.
3) Provide revised plans, specifications, calculations and detailed stormwater narrative that
reflect all changes.
The above requested information must be received in this office prior to March 16, 2007, or your
application will be returned as incomplete. The return of this project will necessitate resubmittal of all
required items including the application fee. If you need additional time to submit the required information,
please mail or fax your request for time extension to this office at the Letterhead address.
If you have questions, please feel free to contact me at [phone].

1. A vicinity map with the elements required on page 4 of the permit application is
shown on Sheet C1.00.
2. Drainage basins have been updated to reflect your comments. Thev are now
delineated to show areas that drain to an outlet, or to a control device. See the
attached full-sized exhibit sheet titled "Drainage Area Map".
3. The numbers in the application, supplements, and plans have been revised, and are
consistent.
4. The grassed swale has been revised and is now an infiltration basin. All stormwater
controls now provide 85% TSS removal.
5. Cross-section/details of all control measures are shown on Sheet C2.01.
6. A new geotechnical report has been given to address all comments, and is specific to
the DWQ requests (borings for the first few feet, permeability, and SHWT). Please
see the last section of the calculations booklet.
7. We have listed 1.5" as the design storm on the supplemental sheets since the only
two choices given in the parentheses next to it is for 1.5" for SA waters, or 1" for
others. We make it clear in the narrative as well as in the calculations for each basin
that since we do not provide a bypass structure, we must capture at least double the
required amount (3" minimum) to mitigate for this.
8. Justification has been provided not only in the Infiltration Basin Supplemental
package, but also throughout the narrative and in the calculations.
9. All requests are being provided with the updated package.

This office received your stormwater application for the subject project on July -17, 2006. F.
preliminary review of the plans and specifications has been completed. Before a stomwater permit can
be issued, the following items must be addressed:
1) Provide vicinity map(see application checklist page 4 of 4).
2) Drainage basins should be delineated to reflect areas that drain to a particular outlet, or
control device (wetlands represent a separate DB; a portion of DB #1 drains to Infiltration
Basin 2).
3) The numbers provided in the application, calculation sheets and supplement/ Sheets do not
match (drainage basins areas, impervious areas, calculations should all be consistent).
4) Adequate stormwater controls should be provided for all impervious areas on site (swales
provide 35 % TSS removal rates and do not meet 85 % TSS requirement - specifically
East parking lot).
5) Provide cross-sections/details of all control measures.
6) Soils Report addresses details for structural purposes; hand borings, on -site, in the area
proposed for infiltration are needed to better address depth to seasonal high water table
(SHWT), permeability, estimated infiltration rates & overall expectation that the system
will work and meet design requirements of rules ( see list of design criteria on supplement
sheet).
7) Application package indicates that 3-inches of runoff is captured and stored in basins.
Information on supplement sheets and calculations do not support these storage
volumes.
8) Infiltration basins must meet all design requirements listed on supplement sheets. If a
particular design requirement is not met; justification must be provided that shows the
alternate design provides, at least equal, or better, treatment. (see specific requirements
on supplement sheet).
9) Provide revised plans, specifications, calculations and detailed stormwater narrative that
reflect all changes.
The above requested information must be received in this office prior to October 26. 2006, or your
application will be returned as incomplete. The return of this project will necessitate resubmittal of all
required items including the application fee. If you need additional time to submit the required information,
please mail or fax your request for time extension to this office at the Letterhead address.

IV. DEED RESTRICTIONS AND PROTECTIVE COVENANTS
The following italicized deed restrictions and protective covenants are required to be recorded for all
subdivisions, outparcels and future development prior to the sale of any lot. If lot sizes vary significantly, a table
listing each lot number, size and the allowable built -upon area for each lot must be provided as an attachment.
1. The following covenants are intended to ensure ongoing compliance with state stormwater management permit number
as issued by the Division of Water Quality. These covenants may not be
changed or deleted without the consent of the State.
2. No more than square feet of any lot shall be covered by structures or impervious materials.
Impervious materials include asphalt, gravel, concrete, brick, stone, slate or similar material but do not include wood
decking or the water surface of swimming pools.

system. These connections to the stormwater control system shall be performed in a manner that maintains the integrity
and performance of the system as permitted.
By your signature below, you certify that the recorded deed restrictions and protective covenants for this project
shall include all the applicable items required above, that the covenants will be binding on all parties and persons
