Lion's Gate Friendly Mart
High Density Project
Pamlico County
Dear Mr. Friedman:
On July 21, 2010 Jeffery Manning of the Division of Water Quality (DWQ) inspected the proposed development in Pamlico County.
This project was inspected for compliance with the Stormwater Permit SW7080807 issued to you on August 25, 2008 for the
development and operation of a High Density Stormwater Project.
The inspection revealed that the project has not yet been completed. As such, you will be rescheduled for an inspection at a later date.
This office would like to remind you that you are limited to the impacts proposed in your application and you must comply with all
operation and maintenance requirements of this permit.
As a reminder, if you change your project you must notify us and you may be required to send us a new application. If the property is
sold, the permit must be formally transferred to the new owners/developers by submitting a Name/Ownership Request Form to the
DWQ with appropriate documentation. Failure to abide by the conditions and limitations contained in this permit may subject the
Permittee to enforcement action by DWQ in accordance with North Carolina General Statue 143-215.6(a) to 143-215.6(c).
If your plans to develop the project have been abandoned and/or the property has been sold with the new owners pursuing a new
development plan and you no longer require a stormwater permit you may request the permit be rescinded. Please submit a Rescission
Request in writing to this Office outlining why the permit is no longer required. The Rescission Request will be considered on its
merits, and may or may not be approved.
Should you have any questions regarding these matters, please contact me at (252) 948-3966.
Siincerely, �/%

Subject Property: Lions Gate Subdivision, Moores Corner

On -Site Determination for Applicability to the Neuse River Riparian Area Protection Rules
(15A NCAC 2B .0233)-EXPRESS REVIEW PROGRAM
Dear Mr. Friedman:
On May 20, 2008, at the request of Stocks Engineering I conducted an on -site determination to
review a drainage feature located on the subject property for applicability to the Neuse Buffer
Rules (15A NCAC 2B .0233). The feature is labeled as "08-0846 a to 08-0846 b" on the
attached maps initialed by me on May22, 2008.
The Division of Water Quality (DWQ) has determined that the feature labeled as "08-0846
a to 08-0846 b" on the attached maps and highlighted in red is not subject to the Neuse
Buffer Rule. Please note that the stream call for the subject drainage extends 50 feet past
the property line as depicted on plan sheet EX-01. The owner (or future owners) should
notify the DWQ (and other relevant agencies) of this decision in any future correspondences
concerning this property. This on -site determination shall expire five (5) years from the date of
this letter.
Landowners or affected parties that dispute a determination made by the DWQ or Delegated
Local Authority that a surface water exists and that it is subject to the buffer rule may request a
determination by the Director. A request for a determination by the Director shall be referred to
the Director in writing c/o John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd.,
Raleigh, NC 27604-2260. Individuals that dispute a determination by the DWQ or Delegated
Local Authority that "exempts" a surface water from the buffer rule may ask for an adjudicatory
hearing. You must act within 60 days of the date that you receive this letter. Applicants are
hereby notified that the 60-day statutory appeal time does not start until the affected.party
(including downstream and adjacent landowners) is notified of this decision. DWQ recommends
that the applicant conduct this notification in order to be certain that third party appeals are made
in a timely manner. To ask for a hearing, send a written petition, which conforms to Chapter
150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail
Service Center, Raleigh, N.C. 27699-6714. This determination is final and binding unless you
ask for a hearing within 60 days.
