S.T. WOOTEN CORPORATION
185 FORLINES ROAD
WINTERVILLE, NORTH CAROLINA
MID -ATLANTIC PROJECT NO. OOOR1578.00
Dear Mrs. Lau:
7AUG i 7 zoos i
As discussed during our telephone conversation of August 5, 2005, Mid -Atlantic Associates.
Inc. (Mid -Atlantic), on behalf of S.T. Wooten Corporation (STW), presents the included
supplemental information for the Notice of intent for coverage under North Carolina General
Permit 140000. It is our understanding that this supplemental information is sufficient for
issuance of the general permit. The requested items are discussed below.
A portion of the site map showing the drainage area to the proposed recycling pond is
included as Attachment A. As shown, the approximate size of the drainage area is 4.5
acres. The proposed recycling pond will receive runoff from the majority of the plants
operations. Runoff from the remaining portion of the site will discharge into a drainage
ditch and ultimately off site through an underground pipe located east of the recycling
pond. This outfall will receive runoff from an empty field located northeast of the
concrete plant along with runoff that contacts portions of the plants material stockpiles.
Please note that the topography noted on this map does reiriect actual finishc-d
topography at the site. STW is conducting grading operations to facilitate drainage to
the recycling pond as outlined by the highlighted drainage area.
The hydrograph plot generated by Hydroflow Hydrographs 2004 (Attachment B)
indicates that the required storage for the 25-year storm is 7,662 cubic feet.
The proposed recycling pond at the site will measure 100' (length) x 30' (width) x 4`
(depth) with sides sloped at a 2:1 ratio. The pond will discharge through a 10' weir. The
pond report generated by Hydroflow Hydrographs 2004 (Attachment C) indicates that -
the total storage capacity of this pond is 16,501 cubic feet,
Addendum to Notice of Intent
S.T. Wooten Corporation
185 Forlines Road
Winterville, North Carolina
August 15, 2005
Page 2
• The capacity of the plant is approximately 270 cubic yards per day. STW estimates that
approximately five gallons of water is used to wash trucks for each cubic yard of
concrete produced. Assuming that approximately 30-gallons of water is used for each
cubic yard of -concrete produced; the washwater generated during each business day
should be reused in the production process.
• The intake for the recycle system will be positioned approximately one -foot from the
bottom of the pond. This leaves approximately three feet for storage of stormwater
and/or freeboard (Attachment C).
• Assuming the water level in the pond is maintained at a depth of one -foot, the
remaining storage capacity of the .pond is sufficient to hold the rain from the 25-year
storm (7,662 cubic feet) plus over one -foot of freeboard (approximately 5,574 cubic
feet).
• A pH contingency plan is included in Attachment D. It is our understanding that such a
plan needs to be in place in the event the pond were to discharge.
To summarize, the recycle system proposed for the subject site is designed such that it will not
discharge in response to the 25-year storm. In addition, in the event of a 25 year storm, there
should be over one -foot of freeboard in the pond for additional storage. Finally, a pH
Contingency Plan will be implemented at the facility. Based on our understanding of the
requirements for permitting and .our telephone conversation of August 5, 2005, this information
is suffice for predicting compliance with permit limits and facilitating permitting.
We appreciate your assistance with this matter. If you have any questions concerning the
contents of this letter or need additional information, please do not hesitate to call me at 250-
9918.

The -following contingency plan is in place 'to help insure that discharges from the
recycling pond are within permit limits for pH (between 6.0 and 9.0).
1. Whenever the water in the recycling pond reaches a level one -foot below the
discharge weir, S.T. Wooten will test water in the pond for pH.
2. Tests will be conducted with pH paper or with a hand-held pH monitor.
3. Tests will be conducted from the surface of the pond near the discharge weir.
4. In the event pH measurements are not within permit limits (between 6.0 and
9.0), S.T. Wooten will employ the use of a Fortrans Model 5000Sk pH Control
System. Literature associated with this system along with an Engineer's
Certification for the system's performance is attached.
5. S.T. Wooten will employ the use of this system until pH readings are
consistently within permit limits or until the water in the pond reaches level
two -feet below the discharge weir.

Fortrans pH CONTROL SYSTEMS ARE COMPLETELY AUTOMATIC
They continually monitor/test the pH of the influent water and compares it to the pH setting of the control unit. If a
change in pH is detected, the controller activates the solenoid valve for the CO2. The pH adjustment chemical is
then fed to the return side of the circulation pump until the pH is again at the proper level set at the controller. The
unit will continuously circulate the water until a change in pH is detected and the treatment cycle begins once
again. the unit also features a digital pH meter connected to a probe in the sample cell to ensure unit is functioning
properly and that the correct pH level is maintained.
Our systems offer precise monitoring and control of the pH in settling basins, lagoons
and other outfall containment devices.
The pH CONTROL SYSTEMS will treat up to 57
gallons per minute - max 20' head pressure.
Unique water circulation design eliminates the
need for separate neutralization tank.
. 1.5" quick connect fittings on inlet and return for
easy hook-up. The standard unit is equipped with
2-20' sections of 1.5" flexible hose with quick
connect fittings. Inlet and outlet fittings at the basin
or lagoon are per our specifications.
Unit is shipped completely assembled. The
chemical controller is preprogrammed to maintain a
pH of 7.5. Just attach hoses and PVC fittings.
• 1 year warranty on all component parts and
housing.
The pH CONTROL SYSTEMS are designed
to treat and maintain a specified pH level
in a body of water usually 100,000 gallons
or less to allow the permitted discharge of.
treated water to the environment. Permits
must be obtained from the local governing
agency to allow any discharge to the
environment. Treated water may be used
for wetting of rock and/or dust control to
aid compliance with storm water run off
regulations. Treated water may be used in
water recycling systems.

Dear Mr. Washburn,
I have enclosed the Engineers Certification of the Model 5000S pH Control
System.
Please note that several changes have been made insofar as manufacturing and
materials used to adjust pH.
Initially, Fortrans Inc had a manufacturing agreement with Coastal Carolina
Supply wherein Fortrans Inc. was responsible for the marketing of the pH Control
Systems and Coastal Carolina Supply was responsible for the manufacturing of
the systems. Fortrans Inc. now designs and manufactures the systems. Coastal
Carolina has signed a non -compete in the design and manufacture of pH control
systems for the ready mixed concrete and related industries.
Fortrans Inc. no longer designs systems that use sulfuric acid to lower pH.
All of our systems now utilize CO2 feed systems. CO2 is less expensive, safer
and readily available to the industry.
Regardless of what chemical is used to control pH, the Model 5000S and Model
5000Sk (Skid Mounted) work the same way to monitor and control the pH in
settling basins, lagoons, and other containment to effectively control the pH in
those areas.
I appreciate your comments today relating to our systems performance at your
facilities to date and look forward to serving S.T. Wooten Corp. needs in'the
future.
Please call me if you have any questions or if I may be of service in any way.
Sincerely,

PURPOSE
G.C. Environmental, Inc., was contracted to provide an engineers review and certification that the
Model 5000-S pH Monitor and Control System manufactured by Coastal Carolina Supply 'in
Morehead City, NC, could effectively provide on a continuous basis, an average pH range of 6-9
units on the supernate layer of a stormwater/rinse water sedimentation basin typically found at Redi-
mix concrete facilities.
SCOPE OF WORK
During theweek of August 11, 2005, G.C. Environmental, Inc_, witnessed'the operation ofthe Model
5000-S self-contained pH Monitoring and Control System at a Redi-mix plant located in Durham,
NC. During the two (2) day test program, measurements were made within the facilities
stormwater/rinse water sedimentation basin for pH, temperature and depth (both supernate and
sludge). 'During the first day of testing, the basin was found to be heavily loaded with solids and
adjustments were made to the solids blanket to complete testing the following day.
TEST METHODOLOGY
A primary sedimentation basin located at a Redi-mix concrete plant located in Durham, NC was
treated utilizing the Model 5000-S pH Monitor and Control System. During.the test program, the
basin was, on a semi -continuous basis, being fed rinse�water from the exterior cleaning of cement
trucks. Measurements for pH, temperature, supernate and sludge blankets were made within the
sedimentation basin. Initial pH measurements showed pH levels of at least 12.0 units. The
sedimentation basin was rectangular in shape with concrete walls and bottom. The basin ranged in
depth of I" at the inlet to approximately 3' at the deepest point. Sludge measurements within the
basin showed that at least 2/3 of the basins depth was comprised of sludge and the remainder
supernate.
The Model 5000-S pH Monitor and Control System was set up at the rectangular sedimentation
basin with the intake and discharge hoses situated at opposite ends of the basin. Both the intake and
discharge lines were set at depths within the supernate layer of the basin. A clockwise flow pattern
was established once the unit began operation and pH and temperature measurements were made at
several locations throughout the supernate layer of the sedimentation basin_ Approximately eighteen
(19) pH and temperature measurements were collected with a mean pH value of 8.56 and mean
temperature values of30.94 CC. The pH system was left to run essentially on a continuous basis over
a four (4) hour period_ An estimated volume existing within the sedimentation basin was 25, 000
Im
gallons with a little over 8000 gallons consisting of relatively clear supernate. The amount of 25%
Sulfuric acid (H^SO,) used to treat the sedimentation basins supernate was approximately 18-20
gallons.
MODEL 5000-5 PR MONITOR AND CONTROL, SYSTEM
The model 5000-5 pH Monitor and Control System is comprised of a Hayward Power Flow E (3/4
hp, 56 GPM) centrifugal pump which delivers raw water to a completely contained pH sensor
connected to a pH meter equipped with control relays which operate two (2) stenner (60 GPD) acid
injection pumps. The acid 25% H,SO is injected into the pump discharge line which empties into the
sedimentation basin. Sulfuric acid is delivered to the system by 15 gallon carbuoys located outside
of the fiberglass weatherproof enclosure which houses all of the aforementioned equipment. On top
of the enclosed is an alarm light which is tied into the pH meter which is activated when pH levels
exceed 8.5 pH units or are below 6.0 units.
CONCLUSION
1. The Model 5000-5 pH Monitor and Control System is an effective system for the pH balancing
of sedimentation basins which are used to collect stormwater runoff and rinse water, commonly found
at Red -mix concrete plants.
2. During the test program an average pH of 8.54 units was measured in the subject sedimentation
basin with a range of 7.95 to 934 measured.
I Sludge levels existing within the rectangular sedimentation ranged from 6.0 inches to 2.0 feet. PH
values after pH stabilization at the sludge/supernate interface were approximately 12.0 units
4. For this test program, approximately 180 mull of sulfates were added to the sedimentation basin
as a result of pH adjustment with 2-41% sulfuric acid.
5. The 5000-5 pHMonitor and Control System is fully automated and provides a pH adjusted waste
water which could effectively be reused within the Redi-mix concrete industry.
