Stormwater Management Permit No. SW7101206
Commerce Park 11
Craven County
Dear Mr. Tayolor.
This letter is to notify you are in violation of Title 15A North Carolina Administrative Code (NCAC) 2H .1000 for failing
to comply with terms, conditions and limitations of Stormwater Management Permit No. SW7101206. Permit Number
SW7101206 was issued to you on January 11, 2011 for the Stormwater Improvements for Commerce Park 11, located at
1315 Commerce Drive, New Bern, Craven County, North Carolina.
On March 2, 2012, Mr. Scott Vinson of the Washington Regional Office performed an inspection to determine the status
of compliance with Stormwater Permit SW7101206 as a result of a request to transfer the permit to Commerce Pond
Owners Association, Inc.. As a result of the site inspection and DWQ file review, the following observations and
deficiencies are noted:
I. Permit Conditions #1. 1 & 2.,
DWQ observed that there is unpermitted off -site drainage from the neighboring property that is draining onto this site and
into the wet detention pond. The off -site runoff is coming from the back half of two buildings labeled S. Market Square
Assoc. Inc. on the plans and drain to the back drive isle of lots 6, 7 and 8, to the collection drop inlets leading to the pond.
This is a violation of Permit Number SW7101206 Conditions 41.1.&2. which state, "l. This permit is effective only with
respect to the nature and volume of stormwater described in the application and other supporting data." and "2. This
stormwater system has been approved for. the management of stormwater runoff as described in Section 1.6 on page 3 of
this permit." This additional drainage area and impervious area adds runoff volume to the detention pond that was not
accounted for within the permitted design. This off -site drainage should be either redirected away from the pond or you
may re-evaluated the pond design calculations to determine if the pond is large enough and properly sized to take this
drainage. If the pond is determined to be large enough as designed, then a request for a permit modification should be
submitted for review and approval by the Division.
I. Permit Conditions 01. 5.
DWQ observed that either the vegetated shelf around the pond perimeter was not properly planted with wetland plants, or
many of the plants did not survive the first year. It is however still late winter and some plants may not be visible due to
dormancy. Please inspect the pond shelf this March for signs of these wetland plants and plant the shelf as needed this
spring in accordance with the approved planting plans.

Notice of Deficiency Response
New Bern, Craven County, NC
2010'018
Dear Scott,
DWQ-WARD
Per our phone conversation a few days ago below are some calculations that address the
status of the pond for the above referenced project. This is in response to your March 7,
2012 Notice of Deficiency Letter.
Item 1 — Off -.site Drainage Concerns
Based on field investigation the additional offsite drainage area now draining to this
project and originally unpermitted is 21,800 SF. This area includes 15,350 SF of
impervious area and 6,450 SF of green area.
Permanent Pool Size Sunimary
Adding this to the onsite project drainage areas and utilizing the original 90% Nutrient
Removal table calculates a required permanent pool area of 9,901 SF. The current
existing pond has been built with a permanent pool area of 8,850 SF. Furthermore by
interpolating between the 90% table and the 85% table we can safely assume that even
with the additional area we are operating at approximately 88% Nutrient Removal
capacity. Additionally the outlet end of the pond outlet structure pipe discharges into a
ditch which has some treatment capacity. Based on these findings we find that the
existing conditions treat the additional stormwater adequately.
Temporary Storage Volume
The current pond has a temporary volume capture capacity of 23,225 CFT. Adding the
new area and its associated runoff will result in a required temporary storage volume of
16,744 CFT, up from the original required temporary storage volume of 14,744 CFT.

THOMAS ENGINEERING, PA
CIVIL ENGINEERINGeLAND DEVELOPMENT.PRO.IECT MANAGEMENT
Therefore, even by adding off -site unpermitted area the existing pond design continues to
offer approximately 38% more storage capacity than is required.
Summary
C-� ,a--`o"=9�9
y jBased on these factors it is our opinion that the off -site drainage areas coming onto the
�, 1 :- �`pi'ojecNiY p bides for better stormwater treatment for these areas without putting the
onsite pond design unnecessarily outside of tolerance levels. Additionally the permittee
S('has no other.method to control this additional off -site discharge.
Item 2 — VeeetatediShelf Planting
0'- X *4-Lifir"TvU
Tv
' Per our phone conversation, the vegetated shelf was planted. We have some pictures of
the sprigs on file, however they are likely dormant at this time or beginning to come out.
Our recommendation is simply to give this time.
Please review and let me know if you need anything further to address this. if you have
any questions or concerns, please advise.
Thank
