Carolina as amended, and other applicable Laws, Rules, and Regulations
PERMISSION IS HEREBY GRANTED TO
S.T. Wooten Corporation
Burton Industrial Park — Concrete Plant for S. T Wooten Corporation
Burton Park Boulevard, Jacksonville, Onslow County
FOR THE
construction, operation and maintenance of two (2) wet detention ponds in compliance with
the provisions of 15A NCAC 2H .1000 and Session Law 2008-211 (hereafter collectively
referred to as the "stormwater rules') the approved stormwater management plans and
specifications and other supporting data as attached and on file with and approved by the
Division and considered a part of this permit.
This permit shall be effective from the date of issuance until May 30, 2021, and shall be
subject to the following specified conditions and limitations:
I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of stormwater
described in the application and other supporting data.
This stormwater system has been approved for the management of stormwater runoff
as described in Section 1.9 of this permit. The stormwater controls labeled BMP #1
and BMP #2 have been designed to handle the runoff from 197,065 and 65,340
square feet of built -upon area, respectively.
3. A 50' wide vegetative buffer must be provided and maintained adjacent surface
waters, measured horizontally from and perpendicular to the normal pool of
impounded structures, the top of bank of both sides of streams and rivers and the
mean high water line of tidal waters.
4. A vegetated filter strip is not required for this pond as it has been designed to provide
an average annual total suspended solids removal efficiency of 90%.
5. The level spreaders shown on the plans are not required under the stormwater rules
and therefore are not considered a part of the approved state stormwater treatment
system. These additional measures are incorporated only by reference and are not
enforceable parts of the permit.
6. The tract will be limited to the amount of built -upon area indicated in this permit, and
per approved plans. The built -upon area for the future development within the
drainage areas of BMP's #1 and #2 is limited to 7,877 and 3,414 square feet,
respectively.

10. BMP #1 will act in a temporary capacity to receive the truck wash water discharge as
per NCG140428. The total additional volume associated with the truck wash operation
is based on a maximum water usage of 55 gallons per truck, 15 trucks per day, each
making 3 trips per day for a total of 2,475 gallons or 331 cubic feet of additional
volume. For purposes of determining the additional wastewater volume over and
above the state stormwater design storm of 1.5", a factor of safety of 5 was applied,
resulting in a total additional volume of 1,655 cubic feet. The total minimum required
storage volume in BMP #1 is below the provided volume of 25,657 cubic feet.
II. SCHEDULE OF COMPLIANCE
1. No truck washing activities shall be allowed during a heavy rainstorm, or immediately
after a heavy rainstorm, or during the time that BMP #1 is discharging via the weir set
at the temporary pool elevation of 38.0, or during the time that the water level in BMP
#1 is rising and is within one inch of going over the temporary pool weir at elevation
38.0.
All truck wash water discharges into BMP #1 shall enter the BMP via the forebay.
3. The stormwater management system shall be constructed in its entirety, vegetated
and operational for its intended use prior to the construction of any built -upon surface.
During construction, erosion shall be kept to a minimum and any eroded areas of the
system will be repaired immediately.

Subject: ST Wooten NCG140428 / SW8 130501
Hunter:
As I was drafting a permit correction to SW8 130501 for BMP #1 to deal with the truck wash water operation
permitted under NCG140428, I noticed a problem. The methodology to arrive at the additional volume
associated with the truck washing operation is correct, however the minimum required volume for BMP #1
reported in the unsealed, undated, recently received Truck Wash Usage Summary, 14,487 cubic feet, is
incorrect. The May 1, 2013 design calculations indicate that the minimum required volume for BMP #1 is
23,550 cubic feet.
Additionally, the temporary volume provided, 16,988 cubic feet, is incorrect. The May 1, 2013 calculations
(and the permit) indicate that the provided volume in BMP #1 is 25,657 cubic feet. If I add 331 cubic feet to
23,550 cubic feet, the new required minimum volume is 23,881 cubic feet. This is still within the pond design

Ken,
I had Linda look at the storage capacity of pond one (see below). It looks ok. However we will be making a correction to
the state stormwater permit to include the info below written by Linda, referring to the NPDES General permit for pond
one and adding an 0 & M condition to prohibit truck washing during a heavy rain storm when the pond level is one inch
or less from the top of the pond. We will come up with more specific language and/or provide a marked up detail of the
outlet structure from the drawings they sent. This correction and marked up detail will be in a written letter to them
from our office.
Sound ok to you?

The 2475 gallons (331 cf) associated with the truck washing is a daily amount. I think we should account for
that daily amount for a total of 5 days. If it doesn't rain for 5 days, during that 5 days, 1,655 cf of volume will
have been added to the pond from truck washing. Using that volume, there's still a cushion of 846 cf in the
pond, 14487+1655=16142. A total of 16,988 cf has been provided in the pond.
If we assume that the minimum volume required and the volume provided in the pond were calculated correctly
in the original permit, then everything looks good.
I would like to see a condition added to our permit that prohibits truck washing during heavy rain, or when the
pond is full and discharging.

Ken — thanks for reminding me about this. Georgette did ask about this when I spoke with her a few weeks ago. I've
attached my justification for the design. Essentially, the grading plan resulted in an "extra" 2500 cf of temporary storage
in the water quality pool. Based on Wooten's data, and the expected activity in the plant, an average of 330 cf of wash

water will be produced. So the wash water will not result in any significant change in the normal water level of the pond,
thereby ensuring that there is always sufficient storage for the stromwater.
This will, however, result in more frequent small discharges, which will need to be monitored by STW.

Hi Hunter,
Here's a perfectly reasonable request to me from Georgette in Wilmington.
As you are aware, we no longer perform and engineering review in the NPDES program for industrial wastewater
facilities.
However, Georgette's request goes to the sufficiency of the BMP under SW8130501 in the state stormwater
management program, the 2H.1000 program. Please forward to me the calcs establishing the sufficiency of that
engineered BMP. I mean, please send me the calcs showing that BMP 1 has been designed in accordance with the
estimated hydraulic loading including the additional flows from ready -mix concrete operations, as per standard state
stormwater design requirements in her program. I'll make a copy for our files, and forward them to her for her files.
If there is something I obviously don't understand, please contact me today.
Thanks,
Ken

Can you send me the calculations and any other documents they provided to you for our stormwater file. As we
discussed (and as I discussed with Hunter Freeman) Did they redesign/enlarge the first pond based on the new

Hi Butch,
Today I've completed the coverage under the NCG14 permit for Burton Industrial Park. I'll put it in the mail
tomorrow. But I'm reporting to you now that you have coverage for the Burton facility, with a signed Certificate of
Coverage, effective today.
We used a set of special conditions in the CDC to address our issues with BMP 1 and BMP 2 and the state stormwater
management permit issued out of Wilmington.

Again, I apologize for the delay on my desk.

DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES
DIVISION OF ENERGY, MINERAL, AND LAND RESOURCES
CERTIFICATE OF COVERAGE No. NCG140428: authorizing STORMWATER AND
WASTEWATER DISCHARGES under the National Pollutant Discharge Elimination System
(NPDES) program.
In compliance with the provisions of North Carolina General Statute 143-215.1, other lawful
standards and regulations promulgated and adopted by the North Carolina Environmental
Management Commission, and the Federal Water Pollution Control Act, as amended,
S. T. Wooten Corporation
is hereby authorized to discharge to the surface waters of North Carolina from a ready -mix
concrete facility located at
Burton Industrial Park Concrete Plant
550 Burton Park Boulevard
Jacksonville, NC
Onslow County
to receiving waters designated as an unnamed tributary to New River, a class C, NSW water in
the White Oak River Basin.
Special conditions of the Certificate of Coverage
1. S. T. Wooten will build and configure the facility in substantial conformity with the
stormwater and wastewater control systems shown on the Site Plan, Sheet No. 2 of 11,
dated and stamped July 2, 2013 by Withers & Ravenel, and submitted with the revised
permit application on July 3, 2013.
2. Only wastewater discharges are authorized for Outfall #01, the discharge from BMP 1 as
presented on the said Site Plan. Authorized wastewater discharges may arise from truck
and equipment washdown activities; from aggregate pile irrigation drainage; and from
truck or drum wash out activities. Any other wastewater discharges are not authorized.
All flows discharging from Outfall #01 will be regulated as wastewater discharges, -and
must comply with the wastewater provisions of NCG140000.,
3. Only stormwater-only discharges are authorized for Outfall #02, the discharge from BMP
2 as presented on the said Site Plan. All flows discharging from Outfall #02 will be
regulated as stormwater discharges. "
4. The permit application represents that this facility is a temporary installation, but the
duration of production activities is uncertain at this time. S. T. Wooten will maintain the
two BMP's shown on the said Site Plan, and at the time that ready -mix concrete
operations cease, the company will refurbish the two BMP's as necessary to insure their
full functionality as the required BMP's under the State Stormwater Management
program permit, SW 8130501. S. T. Wooten will request an inspection of the refurbished
BMP's from the Wilmington Regional Office stormwater staff. Failure to satisfactorily
refurbish the BMP's, or failure to request the stormwater staff inspection is a violation of
the General Permit. The Division may withhold rescission of the General Permit coverage
until satisfactory functionality is established for the two BMP's.

This Certificate of Coverage is an enforceable part of General Permit NCG140000, and shall
become effective for the permittee on August 8.2013.
This Certificate of Coverage shall remain in effect for the duration of the General Permit.
Signed this day, August 8.2013.

under the subject state-.NPDES general permit. This permit is issued pursuant to the
requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the US Environmental Protection Agency dated
October 15, 2007 (or as subsequently amended).
Please note that NCG140000 contains effluent limitations for process wastewater discharges
(see Part IV, Section D). Wastewater discharges must meet the requirements of these
effluent limitations. An exceedence of any of these limitations is a violation of permit
conditions.
This facility already has the additional coverage required under North Carolina water quality
rules at 15A NCAC 2H .1000. Please note that the provisions of that permit SW 8130501
continue to pertain at this site, in addition to the federal NPDES program permit,
NCG140000. The elements of coordination between the two permits are established in the
attached site -specific Certificate of Coverage, NCG140428.
Please take notice that this certificate of coverage is not transferable except upon approval
of the Division of Energy, Mineral, and Land Resources. The Division of Energy, Mineral,
and Land Resources may require modification or revocation and reissuance of the certificate
of coverage. This permit does not affect the legal requirements to obtain other permits
which may be required by the Division of Energy, Mineral, and Land Resources or permits
required by the Coastal Area Management Act or any other federal or local governmental
permit that may be required.
Please note that permit requirements in Part II, Section A, numbers 1-5, and Part II,
Section B, number 1 are no longer valid per NC Session Law 2011-394. However, note that
Part II, Section A, number 6, and Part II, Section B, numbers 2-10 are unaffected by the
Session Law. Those sections will remain in effect for the duration of this permit term.
Please be reminded that your facility must notify the appropriate DEMLR Regional Office at
least 72 hours in advance of operation of your wastewater treatment facility.
