Dear Mr. Corcoran:
Alan W. Klimek, P.E. Director
Division of Water Quality
The Washington Regional Office received a completed Stormwater Application for the subject project on
November 9, 2006. Staff review of the plans and specifications has determined that the project, as proposed, will
comply with the Stormwater Regulations set forth in Title 15A NCAC 2H.1000. We are forwarding Permit No.
SW7060806 dated February 5, 2007 to Atlantic Beverage, Inc. for the construction and operation of a wet detention
pond and a bioretention Basin to serve the expansion of Atlantic Beverage, Inc. located at 1702 Red Robin Lane in
New Bern, NC.
This permit shall be effective from the date of issuance until February 5, 2017 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, 6714 Mail Service Center, Raleigh, NC 27699-6714. 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 Roger
Thorpe or me at [phone].

When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth Linear interpolation should be employed to determine the correct value for non-
standard table entries.
'- In the 20 coastal counties, the requirement for a vegetative filter may be waived if the wet detention basin is designed to provide
90%TSS removal. The NCDENR BMP manual provides design tables for both 85%TSS removal and 90%TSS removal.
II. REQUIRED ITEMS CHECKLIST
The following checklist outlines design requirements per the Stonnwater Best Management Practices Manual
(N.C. Department of Environment, Health and Natural Resources, February 1999) and Administrative Code
Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stonnwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
The forebay volume is approximately equal to 20% of the basin volume.
The temporary pool controls runoff from the design storm event.
The temporary pool draws down in 2 to 5 days.
If required, a 30-foot %egetative filter is provided at the outlet (include non -erosive flow
calculations)
f. The basin length to width ratio is greater than 3:1.
g. The basin side slopes above the permanent pool are no steeper than 3:1.
h. A submerged and vegetated perimeter shelf with a slope of 6:1 or less (show detail).
i. Vegetative cover above the permanent pool elevation is specified.
j. A trash rack or similar device is provided for both the overflow and orifice.
k. A recorded drainage easement is provided for each basin including access to nearest right-
of-way150 .
I. If the basin is used for sediment and erosion control during construction, clean out of the
basin is specified prior to use as a wet detention basin.
m. A mechanism is specified which will drain the basin for maintenance or an emergency.
Hl. NVET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the
vegetated filter if one is provided.
This system (check age) 1104M V does not incorporate a vegetated filter at the outlet.
This system (check one) 9edmae 4 does not incorporate pretreatment other than a forebay.
Form SWU-102 Rev 3 99 Page 2 of 4

Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed.
Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain
proper functioning.
g. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of
in an appropriate manner and shall be handled in a manner that will not adversely impact crater quality (i.e.
stockpiling near a wet detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it gill live an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 2.25 feet in the main pond, the sediment shall be removed.
When the permanent pool depth reads 2-25 feet in the forebay. the sediment shall be removed.

SOIL REPORT
Atlantic Beverage, Inc.
1702 Red Robin Lane
New Bern, North Carolina
A soil boring was conducted on July 31, 2006 in the location of the proposed bio-retention area
to be located on the Atlantic Beverage, me. site. The purpose of the boring was to evaluate the
suitability of the existing soil material for supporting the function of a bio-retention area.
The soil column was observed to exist as follows:

36 Inches to 42 Inches
Whitish Sand
Groundwater was observed to occur at a depth of 40-inches.
Due to existing soil conditions, recommend use sand fill and an underdrain system. Maintain the
bio-retention area at as high of an elevation as possible.
