supercede any other agency permit that may be required. 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,

This form may be photocopied far use as an original
A low density project is one that meets the appropriate criteria for built upon area and transports stormwater
runoff primarily through vegetated conveyances. Low density projects should not have a discrete stormwater
collection system as defined by 15A NCAC 2H .1002(18). Low density requirements and density factors can be
found in Session Law 2008-21 I, 15A NCAC 2H .1000, Session Law 2006-246 and the State of North Carolina
Stormwater Best Management Practice Manual. Curb and gutter systems are allowed provided they meet the
requirements in 15A NCAC 2H .1008(g).

Refer to DEMLR's forms and applications website for specific language that must be recorded in the deed
restrictions for all subdivided projects. (Itttp://portal.ncdenr.ory/web/ir/state-stormwater-forms does)
Complete the following calculation in the space provided below where:
• SA Site Area - the total project area above Mean High Water.
• DF Density Factor - the appropriate percent built upon area divided by 100.
• RA Road Area - the total impervious surface occupied by roadways.
• OA Other Area - the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc.
• No. of Lots - the total number of lots in the subdivision.
• BUA per Lot - the computed allowable built upon area for each lot including driveways and impervious
surfaces located between the front lot line and the edge of pavement.
• Total allowable lot BUA - the computed allowable built upon area for all lots combined.
• Total BUA from lot listing - the sum of built upon area allocated for each lot on the list of non -uniform lots.

effective from the date of issuance until December 31, 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 North Carolina General Statutes, and filed

Subject: Approved Plan Revision / Plan Update.
Harvey Point DTA — PBI Site Expansion
Overall Low Density Commercial Development
with Areas of High Density
Perquimans County
Dear Mr. Gerig:
On August 2, 2010, the Washington Regional Office received a plan revision for Stormwater
Management Permit Number SW7080717MOD. The plan revision is simply to update the Approved Plans to
show the permitted "Future" built -upon area which was included in the original design, just not shown on the
permitted plans. Based on the current permit your plan revision request is hereby approved. It has been
determined that a formal stormwater permit modification is not required for the proposed changes. We are
forwarding you an approved copy of the revised plans for your files. Please add the attached plans to the
previously approved plan set dated June 2, 2010. Please remember to execute a designer's certification (pages 7
& 8 of the permit) once the construction of the project is finished verifying that the stormwater system and
project have been constructed per the approved plans as required under Section 11.11 of the permit and to submit
the originally signed certification to the Division.
Please be aware that all terms and conditions of the permit issued on June 2, 2010 remain in full force
and effect. Please also understand that the approval of this revision to the approved plans for the subject State
Stormwater Permit is done on a case -by -case basis. Any other changes to this project must be submitted to and
approved through the Division of Water Quality prior to construction. The issuance of this plan revision does
not preclude the permittee from complying with all other applicable statutes, rules, regulations or ordinances
which may have jurisdiction over the proposed activity, and obtaining a .permit or approval prior to
construction.
If you have any questions concerning this matter, please do not hesitate to call me at [phone].
Sincerely,
Scott Vinson
Environmental Engineer

Perquimans County
Dear Mr. Gerig:
Dee Freeman
Secretary
The Washington Regional Office received a complete Stormwater Management Permit Application for
Harvey Point DTA — PBI Site Expansion project on May 28, 2010. 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 21-1.1000. We are forwarding
Permit No. SW7080717MOD, dated June 2, 2010, for the construction of the subject project.
This permit shall be effective from the date of issuance until June 2, 2020, 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, 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.
If you have any questions, or need additional information concerning this matter, please contact Scott
Vinson, or me at [phone].

I will keep a maintenance record on this BMP. This maintenance record will be kept in a
NOOENRtown 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.
Important maintenance procedures:
— Immediately after the stormwater wetland is established, the wetland plants will
be watered twice weekly if needed until the plants become established
(commonly six weeks).
— No portion of the stormwater wetland will be fertilized after the first initial
fertilization that is required to establish the wetland plants.
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— Once a year, a dam safety expert will inspect the embankment.
After the wet detention pond is established, I will inspect it 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 will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
