Discussion
Myrl and I visited 5 sites yesterday that are permitted, or seeking permits under the NPDES
stormwater program.
1. PLT, Selma. This ready -mixed concrete facility has an NOI pending on KBP's desk. The
designer included infiltration as a key component of the design. KBP was interested in
whether the already existing infiltration basin was effectively infiltrating the waters from the
site. Some moderate amount of rain had fallen on Saturday night and Sunday prior to our
visit on Monday. I hoped to see a dry pond, or a relatively little bit of water in the basin.
In fact, the whole bottom of the basin was covered with 12' - 18" of water, as estimated by
Rick Proctor, owner. In response to my misgivings about the design basis (infiltration)
brought on by the presence of water, Rick agreed to measure the loss of water (if any) over
the next several days and report that to Ken Pickle. We were unclear on the report time,
but my impression was that Rick would report on Friday of the same week, or on Monday of
the following week. PLT has another ATC/NOI being processed based on the infiltration
design concept. My approval of such a design concept will be influenced by the
performance of the Selma facility.
2. Atlantic Scrap, Benson(?). Myrl made a brief inspection in response to a fire over the
weekend. I was unclear on whether the facility had a point source discharge, whether a
stormwater permit was required, and where to take a sample. No action for KBP.
3. Heritage Concrete, Sanford. A ready -mixed concrete site considering upgrading the
treatment of wastewater. Myrl wanted us to stop by and talk with them about the
requirements for an ATC for the new construction. Here's where I first realized that perhaps
portions of the regulated industry did not understand what we mean when we say we want
"engineered" drawings. Some, apparently, have not understood our demand for an
engineered design as a demand for an accounting of the waters generated on the site.
4. Saiden Technologies, Sanford. An adhesives manufacturer. Discovered a milky emulsion in
the drainage feature at the back of the facility. Unknown material. Plant manager could
not offer an explanation of the cause or even what the material' was. Myri to follow up with
continuing contact with the facility.
5. Lane Construction, Tryon Road and US1, Raleigh, A batch concrete site for road
construction. Inspected the two new settling pits for the pavement sawing operation
wastewater. The small basin was full of solids. The large basin had a pump suction hose
dropped in it and a sediment filter bag in place. The original system seemed choked with
solids for most of the settling volume. There was a mystery pump line that appeared to go
under the highway from the first small settling pit where the truck wash out first begins
treatment.

Please find enclosed the engineers certification of our Model 5000S pH
Monitoring and Control System_
Please note that we no longer use sulfuric acid to neutralize the high pH process
water. We now only use CO2 (gas) to control the pH_ We found that CO2 is much
less expensive and safer_ Plus it is much easier to obtain in mini -bulk quantities
The certification states that the system is manufactured by Coastal Carolina
Supply. Fortrans now manufactures the systems at our facility in Wendell, NC.
I have enclosed one of our technical data sheets as well as pictures of typical
installations. To date we have 24 installed systems.
Please call me if you have any questions or if I may be of service in any way.
Sincerely,

Septcrrmber 1 1, 2003
G.C. Environmental, Inc., was contracted to provide an Gngrn(ers review and certilication that the
Model 5000-S pH Monitor and Control System rttanUflactured by Coastal Carolina Supply in
Morehead City, NC, could effectively provide on a continuous basis, an average pl-I range oF6-9 units
on the supernatc layer of a stormwater/rinse water sedimentation basin typically found al Jtedi-mix
concrete facilities.
SCOPE OF WORK
Duringtheweek of August 11, 2003, G.C. Environmental, Inc., witnessed the Operartionoi'thc Model
5000-S self-contained pH Monitoring and Control System at a Itcdi-mix plant lc)cated in Dunham, NC.
During the two (2) day test program, measurements were made within the; facilitiesS stormwaiter/rinsc
water sedimentation basin for pl-1, temperature and depth (both supernatc and sludge). During the first
day oftGsting, the basin was round to be heavily loadedwith solids and adjustrrrents were made to the
solids blanket to complete; testing the following day.
TEST MFT140DOLOGY
A primary sedimentation basin located at a Redi-mix concrete plant located in Durham, NC: wa,s
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 rinsc water from the exterior cleaning cal" cernent
trucks, Measurements for pl-1, temperature, supernatc and sludge: blankets wcre made within the
sedimentation basin, Initial pH measurements showed pl-I levels eel* at least 1?.0 units, 'I"hc
sedimentation basin was rectangular in shape with concrete wells and bottom. The basin ratng.e:d in
depth of I" at the inlet to approximately Tat the deepest point. Sludge measurements within the basin
showed that at least 2/3 of the basins depth was comprised 01*NIudgc .`end the rcmatiirider supernzrte.
The Model 5000-S pli Monitor and Control Systern was set up at the rectangular sedimentation basin
with the intake and discharge hoses situated at opposite ends ol" the basin, Both the intake: and
discharge lines were set at depths within the supernate layer ol'the basin. A clockwise flaw pattern
was established once the unit began operation and pl-I and temperature; rrlea%rements were made at
several locations throughout the supernate layer- oft lie sedimentation burin. Approximately eighteen
(18) pi -I and temperature measurements were collected with a mean pH value of 8...5.6. and mean
temperature values of 30,94 OC. The, pH system was lell to run essentially on al continuous basis over
a four (4) hour period. An estimated volume existing; within the sedimentation basin was 25, 000
gallons with a little over 8000 gallons consisting; of relatively clear supernatc. '['lie amount of 25%

sedimcntation basin. Sulfuric acid is delivered to the system by 15 gallon carbuoys located out.side of
the fiberglass weatherproof enclosure which houses all ol'the a fbrCfTiCntloned CCluipment. 0n top of
the enclosed is an alarm light which is tied into the pH meter which is activated when pl I levels exceed
3,5 pH units or are below 6.0 units.
CONCLUSION
1, ]'he Model 5000-S pH Monitor and Control System is an QtTective system flor the pl-I balancing of
sedimentation basins which are used to collect stor:11water runoff and rinse water, Goriirnonly lOund
at Red -mix concrete plants,
2. During the test program aii average pi -I of 9,54 units was measured in the subJCCI sedimentation
basin with a range of 7.95 to 9.34 measured.
3. Sludge levels existing within the ranged from 6.0 inches to 2.0 feel, PH
values after pH stabilization at the sludge/supernate intefa.ce werr; approximately 12.0 Units
4_ For this test program, approximately 180111gil ol'sulfates were added to the sedimentation basin as
a result of pH adjustment with 25% sulfuric acid,
5, The 5000-S pH Monitor and Control System is fully automated and provides it pl I ad{usted waste
water which could etTcctivedy be reused within the Redi-mix concrete industry.

FOR TRANS pH CONTROL SYSTEMS
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.
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
stormwater run off regulations. Treated water may
also be used in water recycling systems.
These systems offers 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
2-30'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.
