Dear Mr. Tyson: Pamlico County
The Washington Regional Office received a complete Stormwater Management Permit Application for
the ownership transfer of Dollar General - Grantsboro on October 30, 2012. Staff review of the plans
and specifications has determined that the project, as proposed, will comply with the Stormwater
Regulations set forth in Session Law 2008-211 and Title 15A NCAC 2H.1000. We are forwarding
Permit No. SW7101113 dated May 2, 2011, for the continued construction, operation and
maintenance of the subject project.
This permit shall be effective from the date of issuance until May 2, 2021, 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 operation 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 150E of the

Dear Mr. Barnes:
This office received a Coastal Stormwater permit application and plans for the subject project on November 16,
2010. A preliminary review of the project indicates that before a State Stormwater permit can be issued the following
additional information is needed.
I. The 1.25 inch small diameter draw down orifice will drain the 1.5" storm out of the pond quicker than the 2 day
minimum requirement. Please recalculate the orifice size based on the minimum 1.5" volume or 3,752cf and not on
the total volume provided (8,401 Please revise calculations, plan sheet C-10 & the supplement form as needed.
2. Please submit section III. Required Items Checklist of the wet basin supplement form. (additional tab at bottom of
excel spreadsheet)
3. Please do not forget to have any plans, calculations, supplements, narrative, etc. revised, signed, sealed and dated as
necessary to reflect all changes when re -submitting and to submit 2 copies of any revised plan sheets and/or
supplement forms.
The above requested information must be received in this office prior to February 19, 2011 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.
You should also be aware that the Stormwater Rules require that the permit be issued prior to any development
activity. Construction without a permit is a violation of 15A NCAC 21-1.1000 and North Carolina General Statute 143-215.1
and may result in civil penalties of up to $10,000 per day.
Please reference the Stormwater Project Number above on all correspondence. If you have questions, please feel free
to contact me at [phone].

Wet Detention Basin Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided. `'n=.-1 ~ =_: Ito Kt�
This system (check one): NOV 16 2010
❑ does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
❑ does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minimized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of operation and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
