Dear Mr. Naylor:
As outlined in the State of North Carolina Administrative Code Section 15 NCAC 2H.0105,
Aquaterra, Inc. has prepared this Engineering Proposal.
15 NCAC 21-1.0105 c 1
The waste to be discharged consists of pretreated ground water obtained from a ground water
remediation system. Ground water contaminated with Volatile and Semi -Volatile Organic
Compounds will be pumped from two ground water extraction wells to an air stripping unit,
treated, and discharged to the South Buffalo Creek Tributary A. A copy of the laboratory
analytical results on the influent and a list of additional compounds also found in the ground
water can be found in Attachment A. Laboratory analysis was performed by Industrial and
Environmental Analysts, Inc. of the Research Triangle Park, North Carolina.
15 NCAC 21-1.0105 (c) (2
The proposed treatment system and point of discharge has been selected as the most
environmentally sound and cost effective option. The large volume of water to be pumped
(maximum estimated volume of 216,000 gpd) prohibits the option of pumping and hauling from
the site for disposal on a cost effective basis. Worth Chemical has received a POTW discharge
permit, Permit No. 5-2015, which limits the flow to 15,000 gpd, far below the necessary flow rate
to effectively begin restoration of the aquifer.

Engineering Proposal for NPDES Permit
Worth Chemical Corporation
Page 2
15 NCAC 2H.0105 (c) (3
The proposed air stripping system, designed and built by Four Seasons Industrial Services, Inc.
of Greensboro, North Carolina has been designed to operate at liquid flow rates of up to 150
gpm with an air to water volume ration of approximately 100 to 1. Air and water flow rates may
be adjusted along with system controls to operate at lower capacities if required as a result of
site specific conditions.
Operating conditions are adjusted by valves and controlled by differential pressure and float
switches. Operating conditions are set and monitored using flow meters, level indicators for
liquid flow, and pressure and differential pressure guages for air flow. Provisions are made to
prevent the discharge of inadequately treated water should operating conditions vary from set
operating ranges.
In general, the influent is pumped to the top of the first air stripping column where a spray nozzle
directs the water downward over the column packing material, used to increase the influent's
surface area. Air is blow upward counter to the flow of the influent, volatilizing the organic
compounds. The water from the first column is then collected and the process repeated in the
second column. Essentially all the removals are achieved in the first stage of the two stage
system. Testing of previously implemented air stripping systems has shown removal of up to
99.9% of VOC's. A schematic of the proposed air stripping system is provided in Attachment B.

Attention: Mr. Dale Overcash 1
Reference: NPDES Permit Application Standard Form C
WORTH CHEMICAL CORPORATION - Segal Boulevard
Greensboro, North Carolina
Dear Mr. Overcash:
—eta is
Enclosed find a completed NPDES Permit Application - Standard
Form C for the WORTH CHEMICAL CORPORATION - Segal Blvd.,
Greensboro, North Carolina facility, located as shown in Figure 1.
The application is for a single outfall to handle approximately
216,000 gallons per day of treated discharge from a ground water
remediation system at the site. The extracted ground water will
be treated by two stage air stripping prior to its discharge to
South Bullalo Creek Tributary A, as shown in Figure 2.
Based on present analyses, the raw ground water contains varying
concentrations of volatile and semi -volatile organic compounds.
Testing of a pretreatment air stripping system has shown that
99.5% plus of the volatiles present are removed following
passage through the stripping system. Essentially, all the
removals are achieved in the first stage of the two stage systems.
Effluent analyses from the second stage discharge show all
volatile levels below quantitation limit. Additional analyses
conducted for inorganic constituents (metals) indicate low
levels present in the ppb range.

Pretreatment of the extracted ground water will consist of
treatment utilizing a two (2) stage air stripping system.
Pretreatment of the ground water by subjecting the water to
air stripping has been shown to achieve volatile organic
removals of 99.5% plus of the volatiles present following
passage through the first stage of the two (2) stage system.
Effluent analysis from the second stage discharge show all
volatile levels Below Quantification Level (BQL), with the
exception of one constituent, diethylphthalate, which was
possibly due to the use of cement on the joints of the PVC
piping leading to and from the air stripper. This is evidenced
by the fact that lab analysis of the water samples from all
monitoring wells show the concentrations of diethylphthalate
to be below the quantification level -of 5 ppb.

using test procedures outlined in:
F, t
1) The..North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 22- % (defined as treatment two in the North Carolina procedure
document). The permit holder shall perform guartgrly monitoring using this procedure to establish
compliance with the permit condition. The first test will be performed after thirty days from
issuance of this permit during the months of Ckt . tan. kir. . Jul Effluent
sampling for this testing shall be performed at the NPDES permitted final effluent discharge below
all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (1\1R-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be re -opened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minitntim
control organism survival and appropriate environmental controls, shall constitute an invidid test
and will require immediate retesting(within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
