SUBJECT: Groundwater Remediation Work Plan
Hoechst Celanese Corporation, Shelby, N.C.
RE&I Project B3887.00
Dear Ms. Smith:
RUST Environment & Infrastructure Inc.

Atlanta, GA 30340
Tel. [phone] • FAX [phone]

On behalf of Hoechst Celanese Corporation (HCC), RUST Environment and
Infrastructure (RE&I, formerly SEC Donohue Inc.) is submitting this work plan to extract
contaminated groundwater at the HCC plant in Shelby, North Carolina.
During the August, 1991 groundwater sampling event at the HCC facility, free product
DowTherm A was found in the sample taken from monitor well F-55. DowTherm A is a
heat transfer fluid used at the facility which consists of 1,1-biphenyl and biphenyl ether.
The location of F-55 and other monitor wells in the area are shown in Figure 1. Process
chemicals, including DowTherm, are unloaded and stored in this area of the plant. The
timing, location, and extent of the DowTherm release(s) into the area monitored by F-55
are unknown. The US EPA and the North Carolina Department of Environment, Health,
and Natural Resources (DEHNR) were both notified of the situation.
A special sampling event was conducted in September, 1991 in which F-55, G-50, G-88.5,
H-59, H-79, and U-39 were sampled for semivolatile compounds and 1,1-biphenyl. The
results of this sampling event are listed in Table 1. 1,1-Biphenyl was detected in wells
F-55 and G-50. Bis(2-ethylhexyl)phthalate was also detected in G-50, and
di-n-butylphthalate was detected in U-39.
With the approval of NCDEHNR, HCC installed a pump in well F-55 to recover the free
product DowTherm. The pump operated from January to May of 1992 and recovered
approximately 1 quart of DowTherm.
HCC and RE&I were concerned that other chemicals which are handled in this area of
the plant may also be impacting the groundwater. To evaluate this possibility, wells F-55,
G-50, G-88.5, H-59, H-79, J-28.5, J-59.5, U-39, B-34.5, and BB-18.5 were sampled in
August 1992 for these process chemicals, including butane diol, ethylene glycol, 1,1-
biphenyl, and biphenyl ether. The samples were also analyzed for volatile and
semivolatile compounds. The results of these analyses are summarized in Table 2.
As shown in Table 2, DowTherm A constituents (1,1-biphenyl and biphenyl ether), and
volatile and semi -volatile organics were detected in wells F-55, G-50, G-88.5, H-59 and I

79. Based on these results, the groundwater remediation work will focus on the
groundwater in the area of the F,-G, and H wells.
Three groundwater extraction wells will be installed next to the F, G, and H wells. A
fourth extraction well will be installed between the F and G wells. The proposed
extraction well locations are shown on Figure 2. When these wells begin operation, the
existing pump in monitor well F-55 will cease operation and be removed.
The extracted groundwater will be piped to a chemical sewer line being installed by HCC
for a planned plant modification. This sewer line will discharge into the plant's
wastewater treatment system. The anticipated volume and contaminant concentration
level of the extracted groundwater should not adversely affect the wastewater treatment
process. However, to confirm this, the tr:,atability of the groundwater and potential
impacts on the plant's NPDES permit will be evaluated.
Groundwater samples from each of the four extraction wells will be taken semi-annually.
The samples will be analyzed for volatile and semi -volatile compounds, 1,1-biphenyl, and
biphenyl ether. The results of this sampling and a summary of the system operation will
be submitted to your office within 30 days of receipt of the analytical results.
The extraction system will continue to operate until the regular sampling indicates that no
further operation would be beneficial. This decision will be reached jointly by
NCDEHNR, HCC, and RE&I, and will be justified by appropriate state regulations, the
system operational data, and a risk analysis.
The installation of the extraction system will begin as soon as well permits are issued by
the state. The permit applications were submitted in January. The extraction system
operation will begin as soon as the extraction system and chemical sewer lines have been
installed. This is currently scheduled for May 1993.
If you have any questions or comments on this work plan, please contact me at (404) 458-
9309.
Sincerely,

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Facility requesting permit modification for the addition of 30,000 GPD of contaminated
groundwater from four extraction wells adjacent to the polymer facility. P&E indicates that this
WLA should renew existing limits and only review to see if any new limits or parameters should
be added due to constituents in the contaminated groundwater. Benzene is the only applicable
parameter at this time and the limit should be modified.
*Facility under SOC until September 30, 1994. *Hoechst Celanese interacts with Kings
Mt.WWTP and Minnette Mills.

Facility Name Hoechst Celanese - Shelby Plant Permit # NC0004952 _ Pipe # 001
CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
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 _6.5 % (defined as treatment two in the North Carolina procedure document). The permit holder shall
perform quarterly monitoring using this procedure to establish compliance with the permit condition. The first
test will be performed after thirty days from the effective date of this permit during the months of
_MAR JUN SEP DEC_. 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 (MR-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
4401 Reedy Creek Road
Raleigh, N.C. 27607
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 minimum control organism
survival and appropriate environmental controls, shall constitute an invalid 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.

BUFFALO CREEK jmn

Previous benzene limit (7/90 WLA) was 0.132 lbs/day - Daily Max. and 0.089
lbs/day Mo. Avg. R. Swanek calculated this water quality based limit by the mass balance
equation, using the 7Q10 flow at water supply class of Buffalo Creek.
Cw = (1.19 14/1)(20.55 cfs)/ 0.85 cfs = 28.77 µg/1 or 0.0288 mg/1
0.0288 mg/1* 8.34 *0.55 MGD = 0.132 lbs/day
This limit is incorrect because the average flow (219 cfs) at the water supply class should
have been used in the equation, instead of the 7Q10. (Average flow used because benzene
is a carcinogen). The allowable concentration for benzene based on the water quality
standard is:
New Qw = 0.580 MGD = 0.9 cfs
Cw = (1.19 14/1)(219 cfs)/ 0.9 cfs = 289.6 µg/1 or 0.290 mg/1
0.290 mg/1 *8.34*0.58 MGD = 1.40 lbs/day
The old benzene limit based on the OCPSF guidelines was calculated using the following
flow: 215,000 GPD contact cooling water for polyester resin + 75,000 GPD process water
- polyester fiber = 290,000 GPD
The new OCPSF benzene limit is based on 290,000 GPD + 120,000 GPD Groundwater
Remediation flow = 410,000 GPD.
The new OCPSF benzene limit is 0.465 Ibs/day Daily Max. & 0.127 lbs/day
Mo. Avg. Since this limit is more stringent than the water quality based limit. this is the
limit that should be applied.

Request for Permit Modification
Addition of 30,000 GPD of Contaminated Groundwater
Hoechst Celanese Corporation
NPDES Permit No. NC0004952
Cleveland County, NC
•
Hoechst Celanese Corporation was issued an NPDES Discharge
Permit (No. NC0004952) for the operation of a 0.85 MGD activated
sludge wastewater treatment facility at its Shelby Plant. The
wastef l ow generated from the facility is primarily industrial waste
with some domestic wastewater. Currently, the facility is aver-
aging approcimately 0.38 MGD.
The Company requests that the subject permit be modified to
include the discharge of 30,000 GPD of groundwater contaminated
with organics from extraction wells. The contaminants .found in the
groundwater are Acetone (62 - 128 ug/l), Benzene (28 ug/1), 1,1
Biphenyl (2,100 - 17,040 ug/1), Phenyl Ether (7,220 ug/l) and
Trichloroethane (6 ug/l). With the exception of Benzene, there are
no water quality standards set forth for these compounds. The
water quality standard for Benzene is 71.4 ug/1 (human health).
Since the contaminated groundwater will be treated at the existing
facility prior to discharging, this Office recommends that the
subject request for permit modification be approved as long as
there would be no impact on the wastewater treatment plant that
might effect compliance with the facility's NPDES Permit.
Should you have any questions regarding this matter, please
advise.
