Dear Sir:

Subject: Stormwater Permit Renewal and Ownership Change
Stormwater Management Permit SW7100907
CarolinaEast Heath Systems
Craven County
WM�
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7100907 for a stormwater treatment system consisting of a wet
detention pond serving a medical office located at 960 Newman Road, New Bern, NC
expires on December 31, 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.
The permit was originally issued to CTVAEC Properties, LLC. A search of the Craven
County tax records indicates that your company now owns the property. Stormwater
permits do not automatically transfer when property is sold. Please submit a completed
permit renewal application and an ownership transfer application along with a $505.00
fee. Permit application forms for renewal and ownership transfer can be found on our
website at: hftps://deq.nc.gov/about/divisions/energy-mineral-and-land-
resources/stormwater/stormwater-program/post-construction-2. 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 forms. You can request a copy by e-mailing me at
roger.thorpe(a)-ncdenr.gov.

Re: Soil Evaluation for Stormwater Facility Design
Cardiac, Thoracic, and Vascular Associates, PLLC.
New Bern, NC
On August 30, 2010, a hand augured soil boring was made by me to a depth of 60 inches
below ground level (26.5 ft) in natural soils in close proximity to the proposed
stormwater wet detention pond for the referenced project for the purpose of determining
the seasonal high water table. This information is needed for the design of the permanent
pool level elevation of the proposed stormwater wet detention pond for this project. The
soil type encountered was Torhunta fine sandy loam (To), which is nearly level and very
poorly drained. This soil type also coincides with the mapped soil for this area as shown
in the "Soil Survey of Craven County, North Carolina" as prepared by the US
Department of Agriculture -Soil Conservation Service. The bore hole was left open and
day to day monitoring indicates the current water table to be at a depth of greater than or
equal to 5 feet (Elev. 21.5') below the existing ground surface. This is probably due to
the installation of drainage features located near the tract. Therefore for the purpose of
this application, we find that the seasonal high water table is at approximate
elevation of 21.50 feet.
Attached hereto is an additional soils report from Carolina Engineers, PA. In this report
several 6 foot deep angered holes were drilled to establish bearing capacities and soil
profiles. Note that the water table was not encountered in any of the angered holes.

Dear Dr. Halligan:
This office received a Coastal Stormwater permit application and plans for the subject project on September 22,
2010. A preliminary review of the project indicates that before a State Stormwater permit can be issued the following
additional information is needed.
1. The small diameter draw down orifice has been designed using the larger "provided" storage volume of 5,420cf
and not the minimum required storage volume of 2,539cf. Using the larger storm means that the 1.5" design
storm will drain from the pond quicker than the 2 day minimum allowance. Please redesign the orifice size
based on the required storm volu;ne of 2,539cf and revise the supplement ford calculations and plan sheet 6 of
2. Please provide the outlet invert of the 18" CMP which discharges the pond into the NCDOT right of way to help
verify that the pond will drain properly and that the receiving ditch is low enough. � Qe✓• S� 9/ p✓g .
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. Please also prepare an item -by -item response
letter to help address each individual item requested above. OK
The above requested information must be received in this office prior to October 13, 2010 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, email, 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 2H.1000 and North Carolina General
Statute 143-215.1 and may result in civil penalties of up to $10,000 per day.

Yep, this is all. Thanks, I missed the table but see it now. I should be able to issue the permit as soon as I get this info.
from you.
(I don't know if he told you but John is coming to the office tomorrow morning, he can save y'all some postage.)

Scott,
I will make these changes and resend the report, plans, and forms. The outlet elevation of the pond outlet pipe was
given and is shown on sheet 4 of 8 in the "Pipe Data" table. It is P-2. The ditch elevation varies in the area but is 19.5'
+/- to 20.0' +/- in elevation, so there plenty of room there for positive drainage.
Is this all that is needed?
Thanks,
Bobby Billingsley, PE

Scott,
This is just a follow up on this permit. Can you give me an update on where we are within the time table?
