Stormwater Management Permit SW7960103
Moyock Concrete Plant
Currituck County
Dear Mr. Newsome:
IJ a, p- o
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7960103 for a stormwater treatment system consisting of a wet
detention pond serving the Moyock Concrete Plant located on Windchaser Way near
Moyock, NC expires on April 4, 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 Coastal stormwater rules and the NC General Statutes require a stormwater permit
for this project. Stormwater permits are not automatically transferred when property is
sold. The stormwater permit was originally issued to Coastal Ready Mix Concrete Co.,
Inc. A review of the Currituck County tax records shows that Commercial Ready Mix
Products, Inc. now owns the property. Please submit a completed permit renewal
application and a stormwater ownership transfer application along with a $505.00
processing fee. Permit application forms can be found on our website at:
littl2s://deq.nc.a_ov/about/divisions/enemy-mineral-land-resources/eiieru,v-mitieral-land-
rules/stormwater-program/post-construction. 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

Currituck
Dear Coy Tillet,
The Division of Water Quality issued a Coastal Stormwater Management Permit, Number SW 7960103
to Coastal Ready Mix Concrete for Coastal Ready Mix-Moyock on 1/24/1996. This permit expires on
1/24/2006. Section .1003(h) of 15 A NCAC 2H .1000 (the stormwater rules) requires that applications
for permit renewals shall be submitted 180 days prior to the expiration of a permit and must be
accompanied by a processing fee, which is currently set at $420.00. If this is still an active project
please complete and submit the enclosed renewal application in a timely manner. If this project has not
been constructed and a permit is no longer needed, please submit a request to have the permit
rescinded. If you have sold the project, or are no longer the permittee, please provide the name, mailing
address and phone number of the person or entity that is now responsible for this permit. Enclosed is a
form for change of ownership, which should be completed and submitted if the property has changed
hands.
Your permit requires that upon completion of construction and prior to operation of the permitted
treatment units a certification of completion be submitted to the Division from an appropriate designer
for the system installed. This is to certify that the permitted facility has been installed in accordance with
the permit, the approved plans, specifications and supporting documentation. Please include a copy of
the certification with your permit renewal request and processing fee. Enclosed is a copy of a sample
certification.
You should be aware that failure to provide the Designer's Certification and the operation of a
stormwater treatment facility without a valid permit, are violations of NC General Statute 143-215.1 and
may result in appropriate enforcement action including the assessment of civil penalties of up to
$10,000 per day.
If you have any questions, please feel free to contact me or a member of the coastal stormwater staff with
DWQ at 252-946-6481.

Site Description
Site consists of a concrete ready mixed plant with a material handling storage
facility. Concrete materials are brought to the site by rail and/or truck, stored on
site, and used to prepare concrete mixes as needed. Site includes buildings,
crushed stone driveways, material storage areas and work areas for trucks and
equipment
Stormwater Design Information
Entire Tract = 16.11 acres
Pervious (Farmland) = 8.5 acres
Impervious (I & II) = 7.61 acres
I -Buildings and Concrete = 1.0 acres
II -Gravel Area = 6.61 acres
Storm Water Management System
Sheet flow runoff flows form plant and gravel area into grassy swales which
convey storm water into wet detention pond. Detention pond includes forebay and
outlet control device. Pond is design to achieve 85 percent TSS removel with
surface area based on Table 3.3-2-coastal counties. Ponds temporary storage is
designed to hold the runoff that results from a 1-inch rain and the outlet device is
designed to release this runoff over a 2 to 5 day period. Rains which exceed the I -
inch rain will be released over the emergency overflow. Pond outlet directs
overflow into existing grassy swale which continues for about 400 feet before
empting into drainage ditch. Existing drainage ditch flows toward highway 168.

Site modification
The following modifications will be preformed:
1) Existing pond will be enlarged to satisfy SA/DA ratio as calculated
2) Forebay will be included in new design. Forebay will contain a baffle that
separates the forebay from the remainder of wet detention basin. This baffle
will be ab to 1 foot below permanent pool elevation.
3) The required storage depth will be provided above permanent pool to store
runoff from 1 in storm.
4) A new outlet device will be installed, as shown on plan, to release runoff from
1 in storm over 2-5 days.
5) A 12-foot-wide aquatic bench with a gentle slope (6H:IV) extending to a
depth of 2 feet will be constructed around perimeter of pond.
6) Emergency overflow will be constructed

Wet Detention Pond Specifications
1) Pond Depth of 4 feet
2) Permanent pond surface area of 21,918 sq.ft
3) Permanent pond size (110ftX200ft)

Monitoring and maintenance of stormwater management system
I- Detailed inspection by qualified inspector should occur annually. Schedule
maintenance during wet weather to verify facility in operating correctly.
Qualified inspector should inspect the following:
a) Inspect plantings -grasses and aquatic plants
b) Inspect for settling, woody growth, and animal burrowing.
c) Inspect for excessive erosion or sedimentation in or around the basin
d) Inspect riprap around inlets, outlets, and emergency overflow
e) Check that emergency spillway meets design
f) Check that outlet control is operating correctly
g) Check sediment build-up in pond and swales
II- Operation and maintenance activities should be preformed, by Moyock plant
operator, after every significant runoff and at least monthly.
a) Remove debris and litter at inlet and outlet after storms -producing runoff
b) Check and clear orifice after storms -producing runoff
c) Vegetation management / mowing of grassy swales and area around pond
d) Remove wetland plant when they cover 50% of basin surface. These
plants shall be encouraged to grow along shelf and forebay berm.
e) Check sediment build up every six months, remove if required
f) Check for erosion along swales, pond, inlet and outlet areas
g) Inspect and repair collection system (piping, swales, riprap, etc.)
** Sediment removal is required when basin has lost 25% capacity or swales have lost
25% depth.

Subject: Stormwater Permit SW7960103
Renewal for
Moyock Concrete Plant Site
Currituck County
Dear Mr.Tillett:
This office received your request for renewal of your stormwater permit for the subject project on
June 22, 2006. 1 visited the Moyock plant site on August 23, 2006 and found that the development of the
plant site and the location of the wet pond are different from the originally approved site plan.
I have reviewed the "as built" plans and the calculations submitted along with the application by Mr.
Marcus Felton. Before a stomrwater permit can be issued, the following items must be addressed:
1) Revise stormwater calculations; including SA/DA Ratio, volumes, & outlet orifice.
2) Revise design of outlet structure to provide adequate storage volumes and small diameter
orifice to release design storm in 2-5 days.
3) Provide (2) sets of plans & specifications sealed by an engineer.
4) Provide stormwater narrative that describes modifications to site.
The above requested information must be received in this office prior to October 23, 2006, 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.
If you have questions, please feel free to contact me at [phone].
Sincerely,

COASTAL READY MIX CONCRETE, INC.
MOYOCK FACILITY
STORMWATER MANAGEMENT PLAN
OPERATION AND MAINTENANCE
The proper operation and maintenance of the stormwater
management plan for this facility shall be the responsibility
of the Owner, Coastal Ready Mix Concrete, Inc. The main
features of the stormwater management plan include vegetated
buffers between stone/sand parking and equipment work areas
and grassy swales, grassy swales which convey stormwater to a
wet detention pond, a detention pond with forebay, a pond
overflow swale (vegetated) which allows water to exit the
pond thru a culvert into an existing ditch, and a dry
sediment basin to retain concrete materials derived from
washing out concrete mixers and trucks.
Maintenance of these features shall include the
following measures:
1. Grass in swales and along swale edges shall be
maintained by fertilizing, reseeding and mowing as
needed. Immediate steps shall be taken to repair
any erosion which may occur in the swales and along
the banks and edges. Swales shall be cleaned when
sediment and debris reach 20% to 25% of swale
depths.
2. The sediment basin shall be cleaned out when
sediments reach 1.0' to 1.5' in depth or when
sediments have filled basin outlet swale 20% to 25%
of swale depth or more frequently if deemed
appropriate by the Owner.
3. The detention pond shall be cleaned out when
sediments reach approximately 1' in depth. The
earthen berm within the Dond shall be checked
annually to insure proper operation. Any erosion
which may occur along the pond edges shall be
repaired immediately. Necessary measures to prevent
future erosion shall be performed by the Owner.
Weeds and other debris shall be removed from outlet
swale as needed to allow proper operation.
4. All culverts shall be inspected annually and shall
be flushed out as needed to ensure proper operation.
stor4the undersigned, agree to properly maintain the
ater management system as described above.
