Dear Mr. Olp:
Our records indicate that NPDES Permit No. NC0084301 was issued on July 14, 2005 for
the discharge of wastewater to the surface waters of the State from your facility. The purpose of
this letter is to advise you of the importance of the Permit and the liabilities in the event of failure
to comply with the terms and conditions of the Permit. If you have not already done so, it is
suggested that you thoroughly read the Permit. Of part cular importance are Pages 4, 5 and 6.
Pages 4, 5 and 6 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations. Upon commencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved by
this Agency. For new permits/facilities, the Division may supply an initial small stock of these
forms; however, if you fail to receive the forms, please contact this Office as quickly as possible.
The forms, including directions for their completion, and other important information are also
available at http://h2o,enr.state.nc.us/NPDES/documents.html. It is imperative that all applicable
parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual fee may be required for your facility; if so, you will
receive a statement from our Raleigh Office. It is imperative that the fee be paid in a timely
manner so as to prevent enforcement action or possible revocation of your permit.
The remaining parts of the Pennit set forth definitions,general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions incrude special reporting requirements in the event of noncompliance, bypasses,

treatment unit/process failures, etc. Also addressed are requirements for a certified wastewater
treatment plant operator if you are operating wastewater treatment facilities. Any changes in
operation of wastewater treatment facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment facilities must be permitted or
approved by this Agency.
To maintain compliance with discharge limitations, proper operation and maintenance of
a wastewater treatment facility and the development of a process control program are essential.
For those facilities having chlorine tablet disinfection, please be advised that chlorine tablets
approved for wastewater treatrnent use must be used; swimming pool tablets are not approved.
Also, be advised that DWQ staff need to have access to the facility's discharge point into the
receiving stream; please maintain a path along the outfall line to facilitate that access.
Failure to comply with the terms and conditions of an NPDES Permit subjects the
Permitt.ee to enforcement action pursuant to Section 143-215.6 of the North Carolina General
Statutes. A civil penalty of up to $25,000 per violation (and/or criminal penalties) may be
assessed for such violations. If you find at any time that you are unable to comply with the terms
and conditions of the Permit, you should contact this Office immediately. A Special Order by
Consent (SOC) may be necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a five-year period. Permits are
not automatically renewed. Renewal requests must be submitted to this Agency no later than 180
days prior to expiration. Please make note of the expiration date of your Permit. This date is set
forth on Page 1 of the Permit. Also note that NPDES Permits are not automatically transferable.
If you, as the Permittee, cease to need this Permit, then you should request that the Division of
Water Quality rescind the Permit or request that DWQ reissue the Permit to another party, if
necessary.
As mentioned previously, the purpose of this letter is to advise you of the importance of
your NPDES Permit, Please read the Permit and contact this Office at 704/663-1699 in
Mooresville if you have any questions or need clarification. We look forward to providing any
assistance.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITION
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction orsignificant mortality to Ceriodaphnia
dubia at an effluent concentration of 4.9%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase
11 Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of February, May, August and November. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit,
then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described.
in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998).or subsequent
versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and
further statistical methods are specified in the "North Carolina Phase 1I Chronic Whole Effluent Toxicity Test Procedure"
(Revised-Febniary 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for
the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1
621.
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the
end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response
data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the effluent
toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee
will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit
number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form.
The report shall be submitted to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a ,month in which toxicity monitoring is required, monitoring will be required during
the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality
indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring
requirements or iirnits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later than.
the last day of the month following the month of the initial monitoring.

PART IV - EVALUATION AND RECOMMENDATIONS
The pertnittee is applying for renewal of the permit to discharge wastewater.
The groundwater treatment system on site has not been operated since December of 2001
because the determination was made that it could not further reduce contamination and
some review data indicated that the groundwater remediation system may have been
impeding the natural anaerobic degradation of the contaminants.
Comments submitted in the MRO staff report for the renewal of this permit in March
2001 indicated that the permit holder was pursuing alternative treatment technologies to
remediate this site. Currently the permittee is pursuing an alternative treatment permit
through the Aquifer Protection Section.

Page pour
After- speaking with representative with the Superfand Seam active Hazardous Sites
Branch, MR0 staff has determined that this alternative treatment permit will allow
underground injection of molasses. This will potentially speed up the =aerobic
degradation of the to ehloroethene 1 by providing a food solute to the existing
bacteria. Theon-site groundwater rer iediation system will be used to hold back the plume
if the injection remediation is not effective..
It is recommended that this permit be renewed and include a condition that the permitt
provide correspondence to the Division of rater Quality 0 indicating when the new
remediation technique is initiated and require a report on its effectiveness on
an
basis.

ARCADIS Project No, GS023510,0000
Dear Sir or Madam:
ARCADIS is pleased, to present this National -Pollutant Discharge Elimination
System (NPDES) permit renewal application on behalf of Celanese Acetate, LLC for
the Dreyfus Research Park located in Charlotte, Mecklenburg County, North
Carolina. No changes to the existing permit are requested.
This facility operates a 0.1152 MGD wastewater treatment: system consisting of a
six -tray air stripper and bag filter located. at Dreyfus Research Park, 2300 Archdale.
Drive, Charlotte, Mecklenburg County. The system is has not operated since
December 2001, However, Celanese Acetate, LLC would like to keep the permit
current in case it becomes necessary to operate the system in the future. When the
system was operating, treated wastewater discharged to Outfall 001 into Little Sugar
Creek, which is classified Class C waters in the Catawba River Basin. The location
of this outfall is identified on the attached USGS map.
This wastewater trcatrnent system was designed to remove groundwater impacted
with tetrachloroethene (PCE) and its degradation products, treat the groundwater to
remove the contaminants, and discharge the treated groundwater to Little Sugar
Creek. Analytical data indicate both PCE and trichloroethene (TCE) were -below
detection limits every month while operating, evidencing the air stripper is effective
in removing these organics from the wastewater stream prior to discharge to Little
Sugar Creek,
Site History
Celanese formerly utilized PCE in a dry cleaning operation in the Stoll Building
located on the property. There is an abandoned floor drain system in the Stoll
Building that drains into a storm water sewer. It is thought that small spills of dry
cleaning fluid were probably washed into the floor drains that discharged into a tile
field downgradient of the Stoll Building. Prior investigations suggest that there is
limited residual PCE in the saprolite aquifer at the former Stoll Building storm sewer
outfall and that concentrations are attenuating.

ARCADIS
Alternatives to NPDES Discharge
When operating, the Interim Groundwater Recovery System did not remove
significant PCE from groundwater. The amount of PCE removed from groundwater
can be calculated based on the discharge rate and PCE concentrations in discharged
water. Based on data collected from the 1RM system, the system removed
approximately 6,79 kilograms per year (kg/yr) of PCE in 1996, 3.02 kg PCE/yr in
1998, and 1.86 kg PCE/yr in 2001, indicating a diminishing performance of the
recovery system. Since the groundwater recovery system has not operated since
December 2001, no recent data have been, collected on the effluent stream. All prior
data collected during active operation are maintained on file.
In addition to minimal PCE mass removal, the periodic groundwater analyses
collected while the system was operating suggested that the Interim Groundwater
Recovery System may be impeding natural anaerobic PCE biodegradation near the
recovery wells. The lack of TCE and/or cis-1,2-DCE in recovery well groundwater
analyses suggested that the Interim Groundwater Recovery System may have been
preserving PCE in groundwater, oxygenating the water through increased flow
gradients and reducing the rate of anaerobic biodegradation.
ARCADIS recommended cessation of the groundwater recovery system and
implementation of an In -Situ reactive zone (1R.Z*). Celanese submitted an initial
"Draft Remedial Action Plan, Celanese Acetate LLC, Dreyfus Research Park,
Charlotte, North Carolina" in August 1997, The NCDENR, approved the revised
draft RAP (Power to Carter, January 7, 1999). An additional RAP addendum was
submitted on June 4, 1999 to include Enhanced Reductive Dechlorination (ERD).
The NCDENR approved the 1999 R_AP addendum and directed Celanese to prepare
a pre -construction report for the facility (Power to Carter, July 9, 1999). The source
assessment activities conducted identified relatively low concentrations of
constituents (a dilute plume) rather than concentrations that would be considered
indicative of a source area. Because the concentrations of VOCs in the aquifer were
indicative of a dilute plume rather than a residual source area, it was recommended
that the ERD pilot test — which would have been conducted in a residual source area
— be halted.
A second RAP addendum was submitted in August 2000, which incorporated results
of the ongoing groundwater quality investigation and recommended a pilot test to
evaluate MNA in the groundwater recovery system area (ARCADIS, 2.000). As part
of these activities, with approval from NCDENR the groundwater recovery system
was temporarily shut down in December 2001 to allow an assessment of contaminant
degradation and biogeochemical conditions under non -pumping conditions.
In May 2002 (Caulk to Gahrenas, May 29, 2002), NCDENR requested additional
investigations to more .fully define the extent of groundwater .impacted by PCE, In
response to the request, the "Work Plan for Additional Groundwater and Surface
Water Assessment" was submitted to NCDENR on Jurie 27, 2002. All of the

activities proposed in the work plan have been completed and the available results
were summarized in the Additional Site Characterization Report (ARCADIS,
January 2004).
Celanese currently has an approved 1999 RAP Addendum that includes ERD (in -situ
bioremediation) along the southern property boundary coupled with MNA for the
off -site and Meadows areas. Based on the additional Site characterization and data
collected in 2002 and 2003 with the groundwater extraction system turned off,
Celanese plans to move forward with remedial activities according to the approved
1.999 RAP Addendum,. Historical results indicate that groundwater quality
conditions at DRP comply with North Carolina DENR 1.5A NCAC 2L guidance 1t r
monitored natural attenuation, Consequently, it is not necessary at this time to turn
the groundwater extraction system back on. However, Celanese Acetate would like
to renew the existing NPDES permit in case it becomes necessary to turn the
groundwater extraction system on in the future
This facility is no longer operating and w ill be redeveloped in the coming years.
Therefore, the Celanese representative for this facility, Steve OIp resides in Rock
Hill, South Carolina, If you have any questions regarding this NPDES permit
reapplication, please call.

Dear Mr. Ramsey:
Our records indicate that NPDES Permit No. NC0084301 was issued on September 26, 2001
for the discharge of wastewater to the surface waters of the State from your facility, The purpose
of this letter is to advise you of the importance of the Permit and the liabilities in the event of failure
to comply with the terms and conditions of the Pemiit, If you have not already done so, it is
suggested that you thoroughly read the Permit. Of particular importance are Pages 5 and 6.
Pages 5 and 6 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations. Upon commencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved by this
Agency. If you have not received these forms, they should be arriving shortly, if you fail to receive
the forms, please contact this Office as quickly as possible. I have enclosed a sample of the "Effluent"
reporting form (DWQ Form MR-1), plus instructions for completing the form, It is imperative that
all applicable parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be required
for your facility. You will soon be receiving a statement from our Raleigh Office, It is imperative
that the fee be paid in a timely rnaruier so as to prevent enforcement action or possible revocation of
your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s) The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment

unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment facilities. Any changes in operation of wastewater
treatment facilities, quantity and type of wastewater being treated or discharged, expansions and/or
upgrading of wastewater treatment facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects the Permittee
to enforcement action pursuant to Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $25,000 per violation (and/or criminal penalties) may be assessed for such violations.
lf you find at any time that you are unable to comply with the terms and conditions of the Permit, you
should contact this Office immediately. A Special Order by Consent (SOC) may be necessary while
pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a five-year period. Permits are not
automatically renewed. Renewal requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of your Permit. This date is set forth on
Page 1 of the Perrnit. Also note that NPDES Permits are not automatically transferable, ifyou, as
the Permittee, cease to need this Permit, then you should request that, the Division of Water Quality
rescind the Permit or request that DWQ reissue the Permit to another party, if necessary.

According to your renewal request, received February 2, 2001, the Division of Water Quality
(the Division) hereby transmits your final NPDES Permit. The Division has made no changes to
previous effluent limits and monitoring requirements.
Please be advised that this facility discharges to an officially designated "impaired stream."
Little Sugar Creek has been identified and listed [NCDENR DWQ 303(d) list] as impaired due
to the presence of "...fecal coliform...and sediment based on biological impairment." The
Division acknowledges your efforts to validate problematic Whole Effluent Toxicity (WET) test
results submitted in January of 2001. Thank you for persisting to obtain valid results and your
continued efforts to protect the receiving stream. The Division also acknowledges your intent
to discontinue discharging during this permit cycle and to request that this permit be
rescinded, pending approval of an amended Corrective Action Plan (CAP).
Although other parameters and monitoring requirements remain unchanged, please note that
the Division has reorganized the table under Effluent Limitations and Monitoring Requirements
by "Sample Location" to facilitate operator use.
If any parts, measurement frequencies, or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing upon written request within thirty (30)
days after receiving this letter. Your request must be in the form of a written petition, confoiming
to Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand
is made, this permit shall be final and binding,

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
SPECIAL CONDITION
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia
dubia at an effluent concentration of 4.9 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions. The tests will be
performed during the months of February, May, August, November. Effluent sampling for this testing shall be
performed at the NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit
limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as
described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or
subsequent versions.
The chronic value for multiple concentration tests will he determined using the geometric mean of the highest concentration
having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes,
and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form
(MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and T.HP3B
for the Chronic Value. Additionally, DWQ Forrn AT-3 (original) is to be sent to the following address:

end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response
data, and be certified by laboratory supervisor and ORC or approved designate signature. Total residual chlorine of the
effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream..
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee
will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit
number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the
form. The report shall be submitted to the Environmental Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required
during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality
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, minimum control organism reproduction, and appropriate environmental controls, shall constitute an
invalid test and will require immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority: The Director of the Division of Water Quality.
2. DEM or "the Division" Means the Division of Water Quality, Department of Environment and Natural
Resources.
EMC Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended,
33 USC1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during a calendar month on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month, It is therefore, an arithmetic mean found by
adding the weights of the pollutant found each day of the month and then dividing this sum by the number
of days the tests were reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided
by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic
mean found by adding the weights of pollutants found each day of the week and then dividing this sum by
the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the
permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This limitation is identified as "Daily Maximum," in Part .1 of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar year on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding
the weights of pollutants found each day of the year and then dividing this sum by the number of days the
tests were reported. This limitation is defined as "Annual Average" in Part I of the permit.
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar month on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured during such
month (arithmetic mean of the daily concentration values). The daily con.centrationvalue is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for fecal coliforrn
bacteria is the geo.metricmean of the counts for samples collected during a calendar month. This limitation
is identified as "Monthly Average" under "Other Limits" in Part 1 of the permit.

Part 11
Page 2 of ti
6. b. The "average weekly concentration," other than for kcal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar week (Sund.ay/Saturday) on which daily
discharges are sampled and measured divided by the number of daily discharges sampled and/or measured
during such week (arithmetic mean of the daily concentration 'values). The daily concentration value is equa1.
to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted
by flowvalue) of all the samples collected during that calendar day. The average weekly count for fecal
coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This
limitation is identified as "Weekly Average" under "Other :Limits" in Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If
only one sample is taken during any calendar day the concentration of pollutant calculated from it is the
"Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Part I of the
permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled
and .measured divided by the number of daily discharges sampled and/or measured during such year
(arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average .yearly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved
oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one
dissolved oxygen sample is taken over a calendarday, the. sample is considered to be the "daily average
concentration" for the discharge. It is identified as "daily average" in the text of Part I.
f. The "quarterly average concentration" is the. average of all samples taken over a calendar quarter. It is
identified as "Quarterly Average Limitation" in the text of Part 1 of the permit.
g.
A calendar quarter is defined as one of the following distinct periods: January through March, April through
June, July through September, and October through December.
7. Other Measurements
a. Flow, (MG.D): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is
detemained as the arithmetic mean of the total daily flows recorded during the calendar month,
b. An "instantaneous flow measurement." is a measure of flow taken at the time of sampling, when both the
sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually
without interruption throughout the operating hours of the facility. Flow shall be monitored continually
except for the infrequent times when there may be no flow or for infrequent maintenance activities on the
flow device.
8. Types of Samples.
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and
combined proportional to the rate of flow measured at the time of individual sample collection, or

Part 1I
3 of 11
2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between
samples determined by a preset number of gallons passing the sampling point. Flow measurement
between sample intervals shall be determined by use of a flow .recorder and totalizer, and the present
gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at.
the treatment system, or
(3) a single, continuous sample collected over a 2.4-hour period proportional to the rate offlow.
1n accordance with (1) above, the tune interval between influent grab samples shall be no greater than
once- per hour, and the time intenval between effluent grab samples shall be no greater than once per hour
except at wastewater treatment systems having a detention time of greater than 24 hours. ,In such cases,
effluent grab samples may be collected at time intervals evenly spaced over the 24-hour period which arc
equal. in number of hours to the detention time of the system in number of days. However,. in no case
may the time interval between effluent grab samples be greater than six (6) hours nor the number of
samples less than four (4) during a 24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period csf tune not exceeding 13 minutes;
the grab sample can be taken manually. Grab samples must he representative of the discharge or the
receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided
by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values
values where N is equal to the number of individual value
of the arithmetic mean of the logarithms of the individual
mean, values of zero (0) shall be considered to be one (1).
Nth root of the product of the individual
'he geometric mean is equivalent to the antilog
For purposes of calculating the geometric
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration time
respective flow divided by the summation of th.c respective flows.
10. Calendar 'Day: A calendar day is defined. as the period from midnight of one day until midnight of the next day.
However, for purposes. of this permit, any consecutive 24-hour period that reasonably represents the calendar day
may be used for sampling.
llaz rdous Substance: A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.

PART IV - EVALUATION AND RECOMMENDATIONS
The Permittee, Celanese Acetate, LLC., is applying for renewal of its Ground remediation
permit at the Dreyfus site in Mecklenburg County.
On behalf of the Permittee, Arcadis Geraghty & Miller, Inc., Consultant for Celanese
Acetate, LLC., proposes the following: (quoted from the renewal application)
In a meting with DENR in November 2000, it was agreed that a revised Corrective Action Plan
be submitted for approval to proceed immediately with the monitored natural attenuation remedy.
This submittal is anticipated in January 2000. Celanese Acetate expects DENR acceptance of
this proposed alternative prior to the expiration of the current NPDES permit on August 2001.
However, to allow for continued groundwater remediation in the event of unexpected delays in
the approval, it is requested that NPDES permit NC0084301 be renewed. Upon implementation
of the monitored natural attenuation program, a request to cancel this NPDES permit will be
submitted."
In a telephone conversation with Christine Albertin, with the Superfund Section in
Raleigh, it was learned that. Celanese Acetate, LLC will be given an approval to start a pilot test
for a natural attenuation remedy monitoring program after submittal and approval of such a plan.
However, to this date no plan has been submitted. Moreover, Ms. Albertin indicated that the
pilot test might not work as anticipated, therefore, there continues to be a need for the NPDES
Permit.
It is recommended that the NPDES Permit be renewed pending review by the
Groundwater section.

ARCADIS Geraghty St Miller Project No, GS0235 0,0000
Dear Sir or Madam:
ARCADIS Geraghty & Miller is pleased to present this National Pollutant Discharge
Elimination System (NPDES) permit renewal application on behalf of Celanese
Acetate,ILLC for the Dreyfus Research Park located in Charlotte, Mecklenburg
County, North Carolina. No changes to the existing permit are requested.
This facility operates a 0.1,15.2 MGD wastewater treatment system consisting of a
six -tray air stripper and bag filter located at Dreyfus Research Park, 2300 Archdale
Drive, Charlotte, Mecklenburg County. Treated wastewater discharges to Outfall
001 into Little Sugar Creek, which is classified Class C waters in the Catawba River
Basin. The location of this outfall is identified on the attached USES map.
This wastewater treatment, system was designed to remove groundwater impacted
with tetrachloroethene (PCE) and its degradation products, treat the groundwater to
remove the contaminants, and discharge the treated groundwater to Little, Sugar
Creek. Analytical data indicate both PCE and trichloroethene (TCE) were below
detection limits every month, evidencing the air stripper is effective in removing
these organics from the wastewater stream prior to discharge to Little Sugar Creek.
The attached table summarizes the monthly discharge and effluent monitoring data
as previously reported on DEM Form MR-1. In the past 12 months, the average
discharge was 0.0089 MGD, with a daily maximum of 0.0128 MGD. Quarterly
composite samples for chronic toxicity failed in November 2000, triggering monthly
sampling for chronic toxicity. pH was within the acceptable limits.
Site History
Celanese 'formerly utilized PCE in a dry cleaning operation in the Stoll, Building
located on the property. There is an abandoned floor drain system in the Stoll
Building that drains into a storm water sewer. It is thought that small spills of dry
cleaning fluid were probably washed into the floor drains that discharged onto the
ground downgradient of the Stoll Building. Recent investigations suggested that
there is limited residual PCE in the saprolite aquifer at the former Stoll Building
storm sewer outfall. Our interpretation suggests that most of the dissolved PCE in
groundwater has moved downward to the fractured bedrock.

A he - wives to NPDES Discharge
Since inception, the Interim Groundwater Recovery System has not removed.
significant PCE from ground.water. The amount of PCE removed from groundwater
can be calculated based on the discharge rate and PCE concentrations in discharged
water. The discharged mass of PCE removal from groundwater on an annual basis is
0.53 lb./year. In addition to minimal PCE mass removal, the periodic groundwater
analyses suggest that the interim Groundwater Recovery System may be impeding
natural anaerobic PCE biodegradation near the recovery wells. The lack. of TCE
and/or cis-1,2-DCE in recovery weirgroundwater analyses suggests that the interim
Groundwater Recovery System may be preserving PCE in groundwater by reducing
PCE degradation. The Interim Ciroundwater Recovery System may oxygenate the
water by increased flow gradients and reduce PCE biodegradation. The data suggest
normal dissolved oxygen concentrations impede anaerobic biodegradation.
ARCADIS Geraghty & Miller has recommended cessation of the groundwater
recovery system. Since the groundwater recovery has been ineffective, ARCADIS
Geraghty & Miller has proposed monitored natural attenuation as the remedial
system to clean up degraded groundwater at the Dreyfus Research Park facility, We
believe that the results of the recent investigations summarized in the Remedial
Action Plan Draft Addendum:for Monitored Natural Attenuation (ARCADIS, 31
August 2000) show that the groundwater quality conditions at the Dreyfus Research
Park facility comply with North Carolina DENR 15A NCAC 21, guidance for
monitored natural attenuation. In a meeting with DENR in November 2000, it was
agreed that a revised Corrective Action Plan he submitted for approval to proceed
immediately with the monitored. natural attenuation remedy. This submittal is
anticipated in Januar>, 2000.
Celanese Acetate expects DENR acceptance of this proposed alternative prior to the
expiration oldie current NPDES permit on 31 August 2001, However, to allow for
continued groundwater remediation in the event of unexpected delays in the
approval, it is requested that NPDES perrnit NC0084301 be renewed. Upon
implementation of the monitored natural attenuation program, a request to cancel
this NPDES permit will be submitted.
If you have any questions regarding NPDES perrnit reapplication, please call..

Dear Mr. Ramirez:
The Division has reviewed your letter of May 2, 2006, which states the subject facility is not being operated
and therefore is not producing any wastewater discharge. You indicated the facility wishes to dismantle
the existing remediation system.
After considering the recommendations of the staff in the Mooresville Regional Office, I have agreed to
waive the requirement to submit monthly DMRs for the subject facility, effective June 1, 2006. The DMRs
up through (and induding) May 2006 should be submitted as usual. You are also granted permission to
remove the remediation system.
Be advised that if and when any wastewater discharge resumes, the discharge must be monitored as per
the terms of the NPDES permit and other applicable rules or statutes. Please keep the Mooresville
Regional Office apprised of any pertinent developments that arise regarding this facility, especially if the
facility is re -activated.
While requirements for operator visitation, monitoring and reporting are being waived, your company is
still required to pay the Annual Administering and Compliance Monitoring Fee that is associated with this
and all NPDES permits.
If you have any questions, or if you wish to request rescission of this permit, contact Charles H. Weaver, Jr.

GENERAL:
The facility was last inspected on May 2, 2002 by Mr. Derrick A. Barris of the
Mecklenburg County Water Quality Program (MCWQP). A Compliance Evaluation Inspection
report was issued on May 20, 2002,
PERMIT:
The portion of the facility associated with the NPDES treatment works and discharge
consists of a groundwater remediation system (GWRS) with an influent holding/settling tank, two
air stripper racks, effluent clearwell with effluent pumps and sock filters, and continuous
recording effluent flow measurement.
The facility was issued a new NPDES permit on September 26, 2001. The permit became
effective November 1, 2001 and expires July 31, 2005. A permit renewal application is being
processed. The current permit properly describes the facility and appears adequate for the waste
stream being treated.
RECORDS/REPORTS:
Discharge Monitoring Reports (D1 Rs) were reviewed for the period November 2003
through February 2005.
Records, reports and Logs are clear and well maintained.
FACILITY SITE REVIEW:
During the last inspection, the ground water remediation system was involved in a trial
shut down period for six (6) months. For this inspection, the ground water remediation system
remains shut down, but the current permit has not been rescinded. The systems last discharge
was in November 2001.
FLOW MEASUREMENT:
Flow measurement is accomplished using a totalizer/continuous recording flow meter on
the effluent pumps in accordance with NPDES permit requirements.
LABORATORY:
Analysis of effluent samples is performed by Prism Labs. Chronic Toxicity analysis is
performed by ETT Environmental Inc. Both laboratories are certified by the State of North
Carolina to perform analysis on all parameters specified in the permit. Prism Labs and ETT
Environmental Inc. were not evaluated under this inspection.

EFFLUENT t;ATERS:
The system discharges into Little Sugar C - k, which is a Class C water in the Catawba
River Basin.
There has not been a discharge t the receivingwaters rorr the groundwater e ediation
system since November 2001.
SELF-MONITO NG FROG

Dear Permittee:
Your NPDES permit expires on July 31, 2005. Federal (40 CFR 122.41) and North Carolina (15A NCAC
2H.0105(e)) regulations require that permit renewal applications must be filed at least 180 days prior to expiration of
the current permit. If you have already mailed your renewal application, you may disregard this notice.
To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than
February 1, 2005. Failure to request renewal by this date may resutt in a civil assessment of at least $500.00. Larger
penalties may be assessed depending upon the delinquency of the request.
If any wastewater discharge will occur after July 31, 2005, the current permit must be renewed. Discharge of
wastewater without a valid permit would violate North Carolina General Statute 143-215A; unpermitted discharges of
wastewater may be assessed civil penalties of up to $25,000 per day.
If all wastewater discharge has ceased at your facility and you wish to rescind this permit, contact me at the
telephone number or address listed below.
Use the enclosed checklist to complete your renewal package. The checklist identifies the items you must
submit with the permit renewal application. If you have any questions, please contact me at the telephone number or

GENERA
The facility was last inspected on June 7, 2001 by Mr. Derrick A. Harris ofthe
Mecklenburg County Water Quality Program (MCWQP). A Compliance Evaluation inspection
report was issued on June 21, 2001.
PERMIT:
The portion of the facility associated with the NPDES treatment works and discharge
consists of a groundwater remediation system (GWRS) with the influent holding/settling tank,
two air stripper racks, effluent clearwell with effluent pumps and sock filters, and continuous
recording effluent flow measurement.
The facility was issued a new NPDES permit on September 26, 2001. The permit became
effective November 1, 2001 and expires July 31, 2005. The current permit properly describes the
facility and appears adequate for the waste stream being treated.
RECORDS/REPORTS:
Discharge Monitoring Reports DMRs) were reviewed for the period March 2001
through February 2002.
Records, reports and logs are clear and well maintained.
FACILITY SITE REVIEW:
The ground water remediation system is currently involved in a trial shut down period for
six (6) months. The system's last discharge was in November 2001. The trial period is scheduled
to be complete May 31, 2002. Celanese Acetate will meet with DENR on May 9, 2002 to
determine if the trail shut down will result in a permanent shut down and a rescission of the
current permit.
The facility discharges to Little Sugar Creek, which is Class C water in the Catawba
River Basin.
FLOW MEASUREMENT:
Flow measurement is accomplished using a totalizer/continuous recording flow meter on
the effluent pumps in accordance with NPDES permit requirements. Calibration of the flow
measurement device is performed semi-annually.

LABORATORY:
TOR
Analysis of eff°luent samples is performed by Prism Labs, Clunnic Toxicit al}psis i

(TRE) which is a site -specific study designed to identify the causative agents of effluent toxicity, isolate
the sources of toxicity, evaluate the effectiveness of toxicity control options, and then confirm reductions
in effluent toxicity. Please be aware that North Carolina. General Statutes provide for assessment of civil
penalties for violations of NPDES permit limitations and requirements.
The reverse side of this Notice contains important infornation concerning your Whole Effluent
Toxicity Monitoring and Reporting. Requirements. Please note updated mailing addresses for submitting
your Discharge Monitoring Reports (DMRs) and Aquatic Toxicity (AT) Test Forrns. We encourage you
to review this information and if it would be helpful to discuss this situation or possible solutions to
resolve effluent toxicity noncompliance, please contact. Mr. John Lesley with this office at (704) 663-

of the reporting period (eg,,January test result is due by, the end of February).
Toxicity test condition language contained in your NPDES permit. may require use of multiple concentration
toxicity testing upon failure of any single quarterly toxicity test, If the initial pass/fail test fails or if the chronic.
value is lower than the permit limit, then at least two multiple concentration toxicity tests (one per month) will
be conducted over the following two months. As many analyses as can be completed will be accepted. If your
NPDES permit does not require use of multiple concentration toxicity testing upon failure of any single
quarterly test, you may choose to conduct either single concentration toxicity testing or multiple concentration
toxicity testing per the Division's WET enforcement initiatives effective July 1, 1.999, Follow-up multiple
concentration toxicity testing will. influence the Division's enforcement response.
Toxicity testing months are specified by the NPDES Permit, except for NPDES Permits which contain episodic

The previous permit, issued to Hoechst Celanese Corporation, became effective October 1, 1996 and
expires October 31, 2001. This permittee applied to the Division for a name -change to Celanese
Acetate, LLC (approved December 30 1997) who subsequently applied for permit renewal on
February 2, 2001.
Waste Load Allocation (WLA), The Division prepared a WLA in August 1994and developed
effluent limits and monitoring requirements based on influent to a groundwater remediation system an
in -stream waste concentration (1WC) of 4.9 %,H The Division judges these limits and monitoring
requirements to be appropriate for this renewal (see PERMITTING APPROACH SUMMARY),
Verifying Existing Stream Conditions. This facility discharges to the Little Sugar Creek, a Class C
stream within the Catawba River Basin, Little Sugar Creek is an "impaired waterbody" listed in
NCDENR / DWQ 303(d) list as impaired due to the presence of "...fecal coliform....sediment, and...
sediment based on biological impairrrient"7 Considering that this treatment facility does not generate
fecal coliform or sediment, the Division does not anticipate that the perrnittee will contribute to these
use -impairments currently identified as impacts to the receiving stream,
COMPLIANCE REVIEW
Notices of Violation (NOVs). The Division has issued no NOVs for this facility within the. last three
years,
Whole Effluent Toxicity (WET) Test. This facility conducts quarterly Whole Effluent Toxicity
(WET) testing (1WC 4.9%). Records indicate PASS for fifteen (15) quarters since startup in 1996,
however the facility failed WET testing in November 2000, triggering monthly sampling. Subsequent
results indicate: Pass at 35,4% (DEC); Late (Jan); Pass >50%,. Pass (Feb). However, correspondence
between the permittee and the Division's Aquatic Toxicology Unit document invalid laboratory
results associated with the WET Test failures.9 The laboratory apparently violated test protocol by
using test organisms beyond the test -restricted age. Subsequent testing in February and May 2001
indicate Pass.
Discharge Monitoring Reports (DMR) — Data Review. The Division reviewed DMRs for 17
months (January 2000 through May 2001). Reports appear regular, thorough, and complete.
Discharge during this time period averaged 0.0716 MGD or about 63% of permitted capacity."
During this time period, the parameters of concern (TCE, PCE) were not detected in the effluent. Due
to relatively high dilution, (iWC 4.9 %), this facility is not required to monitor the receiving stream,
FACILITY INSPECTION
The Mooresville Regional Office (MRO) informed the NPDES Unit that the facility was "...in good
operational condition..." and recommended "...that this permit be renewed...." The MRO also noted
that this facility intends to apply to the Groundwater Division and EPA for an addendum to the
Corrective Action Plan (CAP), to pursue the "natural attenuation alternative" and to discontinue
discharge. If the addendum is approved, the permittee will apply to the 'NPDES Unit to rescind this
permit,'

GENERAL:
The facility was last inspected by Darrin M. Peine of MCDEP on June 20, 2000. A
Compliance Evaluation Inspection/NOV report was issued on July 10, 2000.
PERMIT:
The portion of the facility associated with the NPDES treatment works and discharge
consists of a groundwater remediation treatment system (GWRS) with influent holding/settling
tank, two air stripper racks, effluent clearwell with effluent pumps and sock filters, and
continuous recording effluent flow measurement,
The NPDES permit for the facility expires on August 31, 2001. The permittee has
submitted an application for permit renewal. The current permit properly describes the facility
and appears adequate for the waste stream being treated.
RECORDS/REPORTS:
Discharge Monitoring Reports (DMRs) were reviewed for the period March 2000 through
February 2001.
Copies of effluent analytical results, correspondence, and maintenance records are
maintained on -site. Records, reports and logs are clear and well maintained.
FACILITY SITE REVIEW:
The facility discharges to Little Sugar Creek, which is a Class C water in the Catawba
River Basin,
All of the major components of the facility were in service and appeared to be operating
properly at the time of the inspection.
FLOW MEASUREMENT:
Flow measurement is accomplished using a totalizer/continuous recording flow meter on
the effluent purnps in accordance with NPDES permit requirements. Calibration of the flow
measurement device is performed semi-annually.
LABORATORY:
Analysis of effluent samples is performed by Prism Labs. Chronic Toxicity analysis is
performed by ETT Environniental Inc. These laboratories are certified by the State of North
Carolina to perform analysis on all parameters specified in the permit, Prism Labs and ETT
Environmental Inc, were not evaluated under this inspection.
EFFLUENT/RECEIVING WATERS:
The effluent was very clear at the time of the inspection. No adverse impact on the
receiving stream (Little Sugar Creek) was observed at the time of inspection.

Toxicity Testing Protocol

NPDES No. NC0084301
Mecklenburg County
April 20, 2001
During a recent laboratory inspection performed at ETT Environmental, our office examined. the laboratory
bench sheets associated with the 2/14/2001 chronic toxicity test that was performed on Hoechst C'elanese's effluent.
Our office found that the test organisms used to perform this test were greater than 24 hours old when this test was
initiated. Protocol guidelines require that the Ceriodaphnia (labia used in the test procedure have to be Tess than 24
hours old when the test is initiated. The bench sheets for this 'test show that these test org.anisnts were born on
2/13/2001 between 16::30 and 21:30. The test for Hoechst Celanese was not initiated until 2/14/2001 at 1 7:00.
Therefore, we have recorded the 2/1.4/2001 analysis as invalid,
If a chronic value greater than 50% was subtnitted on Hoechst Celanese`s monthly monitoring reports (DMR)
for February 2001, we remind you that the DMR submitted to the Division's Central Piles anust be amended, The
effluent DMR. facility information must be completely tilled out (at the top of the sheet), and the farm should have
"CORRECTED COPY- written or typed at the top. The parameter code of your particular toxicity test should be re-
entered. in an appropriate column with a brief explanation that the test was not suitable as performed.

2000 through November 2000 as discussed on January 3, 2001.
During a review of Celanese Acetate's NPDES Form MR-1 submittals, it was
discovered that a transcription error had occurred for 50050 Daily Effluent Flow
Rate during this period. The transcription error was that the daily effluent flow rate
was reported in hundred thousand gallons instead of million gallons. Thus, the site's
flow rate was actually less during these .months than what had originally been
reported. Please update our file with the amended forms.
Celanese Acetate is committed to ensuring compliance with all County, State, and

Dear Ms, Sullins:
Please find three copies of the attached NPDES Permit Application package for
review and approval. The application was prepared, using the short form for
ground water discharge, in accordance with the North Carolina Department of
Environment, Health, and Natural Resources (NC DEHNR) instruction package.
Extraction well and stream sampling was conducted to provide data to support NC
DEHNR development of the NPDES permit.
The results of the analytical work and the water quality standards for Class C
streams in North carolina are shown on Tables 2-1 and 2-3. The tables show that.
the discharge of 80 gpm of treated ground water, allowing for the elevated TSS
which will not be present in the more full developed wells, will only create a
water quality issue for iron and possibly manganese. The attached correlation
plot of existing ground water monitoring well iron and TSS data shows a linear
relationship and indicates the treatment system influent should contain less
than 5 mg/L of iron. The treatment system will oxidize and filter the iron,
further lowering the discharge iron concentration. Field aeration and filtration
testing of a composite extraction well water sample produced an iron
concentration of <0.1 mg/L. Using this value, the existing water quality in
Little Sugar Creek will not be affected by the treated ground water discharge.
RMT discussed this with the NC DEHNR modeling department and NC DEHNR said that
the iron and manganese parameters would rarely receive a permit limitation.
Considering the fact that the TSS will be significantly lower in the operating
wells, the treatment system discharge will not cause water quality problems in
Little Sugar Creek.
Sincerely,
PEM Carter

GENERAL INFORMATION
MAY 1994
SECTION 1
Hoechst Celanese Corporation (HCC) voluntarily implemented investigations at the Dreyfus Research
Park (DRP) Facility to identify and characterize the potential to which the environment may have been
affected by previous operations at the site. The results of these investigations led to a Remedial
Investigation (RI) which began in 1991 and was implemented in two phases. In September 1993, on
the basis of preliminary data indicating possible off -site contamination, HCC reviewed with the
community the off -site ground water conditions and the plans to implement an Interim Remedial Action
(IRA) system as soon as possible,
This National Pollution Discharge Elimination System (NPDES) Permit Application addresses the
disposal of treated ground water from the IRA system and includes an Evaluation of Wastewater
Disposal Alternatives as required by the NPDES Permit Application short form C-GW.
1.1 Facfitt Information
The DRP site consists of approximately 127 acres in Mecklenburg County, North Carolina. The facility,.
which has been in operation since the early 1950s. is a research and development operation for
several HCC business units, including Textile Fibers, Industrial Fibers, Polymer and Filter Products, and
New Business Development. Figure 1-1 shows the site location.

GROUND WATER TREATMENT SYSTEM DESCRIPTION
MAY 1994
SECTION 2
The IRA process design is based on the data obtained during the RI and RMTs experience with similar
remedial actions. The following sections present a description of an IRA system.
2.1 Extraction Well Locations
Proposed extraction well locations for the IRA have been selected based on tetrachloroethene (PCE)
and trichloroethene (TCE) concentrations in ground water and subsurface geologic conditions along the
southern property line, as shown on Figures 2-1 and 2-2, respectively. Extraction wells for the IRA are
proposed for areas of the aquifer that have PCE and TCE concentrations greater than 0.01 mg,/ in the
ground water. Preliminary capture -zone modeling indicates that the proposed interim extraction well
operation will intercept most of the ground water flow at the property line that migrates directly to off -
site residential areas.
2.2 Ground Water Extraction and Treatment
This section presents a description of the IRA ground water extraction and treatment system and a
summary of the process design basis.
2.2.1 System Description
The IRA System is based on two manifold jet pump systems that have one return tank and two
recirculation pumps. The return tank and recirculation pumps serve multiple wells operating in
parallel via a pipeline manifold for the recirculation water. Figure 2-3 shows this approach on
the Process Flow Diagram.
Manifold jet pump wells will extract the ground water for the IRA. A jet pump is essentially a
combination nozzle and Venturi section that has no rnoving parts. Figure 2-4 shows the basic
jet pump assembly that will be positioned near the bottom of the extraction wells. When water
is circulated under pressure through the jet pump (Q,), a vacuum is created that induces
ground water from the well (Q2), which becomes entrained in the circulation water (Q, + Q2).
The combined flow (Q, + 02) is conveyed under pressure to an aboveground tank, also called a
return tank, and water from the return tank is recirculated (0,) to the jet pump assembly using

SECTION 2
a constant rate centrifugal pump, This is a continuous process, and the overflow from the
return tank is equal to the ground water extraction rate (Q2). This approach can be applied to
extraction wells operating in parallel by means of a manifold recirculation pipeline, as shown on
Figure 2-3. Manifold jet pump systems have been applied successfully at remedial action sites
containing PCE and TCE in the ground water in the Piedmont region.
This approach has the following advantages:
(1) Low well yields from 1 to 6 gallons per minute (gpm) are anticipated for the
interim ground water extraction system, based on low hydraulic conductivities
measured in existing monitoring wells. Standard submersible pumps under
these conditions require cyclic on -off operations using level controls to prevent
the submersible pump from running dry. However, these conditions are not
detrimental to the jet pump assembly, resulting in efficient ground water
extraction and lower maintenance requirements;-
(2) Power controls are only required for the recirculations pumps and air stripper
and not at each extraction well.
The manifold pipeline of the jet pump system is readily expandable to other
wells that may be needed later.
Due to the 1,600-foot long corridor in which the wells will be located along the property fine, two
or more manifold jet pump systems will be used. One return tank will serve both systems. The
IRA design has been developed to allow for additional extraction wells that may be required
later.
The overflow from the return tank will flow by gravity through a flow -measuring flume to a low
profile air stripper, eliminating the need for a Iift station which is commonly required for packed
tower air strippers. The flow to the air stripper will be equal to the total ground water extraction
rate from the extraction wells. The rate of this flow will be continuously recorded and totalized.
The collected ground water will drain into the top of a low profile air stripper and then flaw to
one end of the top tray. The water will flow back and forth across the tray through a series of
baffles that run the length of the tray and will then discharge over a weir to the tray below„

RMT NPDES PERMIT APPLICATION
HOECHST CELANESE DREYFUS RESEARCH PARK
MAY 1994
SECTION 2
Each tray is a sieve tray, and air will flow upward through the holes in each tray at a sufficient
velocity to prevent the water from "weeping" through the holes. Figure 2-5 shows a cut -away
view of a typical low profile air stripper.
The water will be aerated sufficiently to create a froth, which will produce a large contact
surface area between the air and water without the use of packing. As a result, PCE and TCE
will be volatilized from the water phase to the air phase. Air emissions containing PCE and
TCE will be processed first through an air heater for dehumidification and then through two
activated carbon vessels in series. Fugitive volatile organic compound (VOC) emissions from
the return tank and overflow flume will be contained and vented to an activated carbon vessel,
The treated ground water will flow from the air stripper to a lift station. All the treated ground
water will be pumped through a bag filter system to remove low levels of precipitated inorganics
that may be present due to oxidation in the air stripper. The treated ground water will then
gravity flow to a diffuser located in Little Sugar Creek.
2.2.2 System Effluent Quality
The ground water treatment system has been designed to treat 80 gallons per minute of ground
water on a continuous basis. In April 1994, ground water samples were collected from six
ground water extraction wells and analyzed for total suspended solids (TSS), the eight RCRA
metals, calcium, iron, magnesium, and manganese,
A portion of the ground water samples collected from each well was combined and aerated for
10 minutes in order to simulate air stripping conditions. The water was then analyzed for
compositional and dissolved concentrations of calcium, iron, and manganese.
Two 24-hour composite water samples were obtained from Little Sugar Creek and analyzed for
TSS, the eight RCRA metals, calcium, iron, magnesium, and manganese.
Table 2-1 summarizes the analytical results, and laboratory reports are provided in Appendix A.

of Little Sugar Creek at 7010 flows and receiving treated effluent. The following discusses
their significance to meeting the instream water quality standards.
1w09,91513 eva+cd}94
Chromium
The estimated treatment system effluent concentration of 0.068 mg/L is slightly above
the WQS of 0.050 mg/L. When a summer 7Q10 dilution factor of 3.5 cfs is used, the
estimated instream chromium concentration is 0.013 mg/L,, which is substantially below
the WQS of 0.050 mg/L.
iron
The projected instream iron concentration is 2,15 mg/L, assuming the high TSS is
present in the treated ground water discharge. This wilt not be the case, as historical
ground water monitoring well data has consistently shown TSS concentrations below
50 mg/L. The extracted ground water is expected to contain similar TSS levels when
the wells are fully developed. Figure 2-6 presents a correlation plot of extraction well
TSS and iron concentrations. The plot establishes the linear relationship that shows
that treated extracted ground water should have a total iron concentration below 5
mg/L. This agrees with the historical average iron concentration of 1.4 mg/L in the
ground water samples collected from monitoring wells.
Aeration and filtration tests, conducted to simulate the proposed air stripper and bag
filter treatment system, indicate the actual discharge value should be <0.10 mg/L, which
is below the WQS of 1.00 mg/L. Since the treated ground water will be air stripped and
Tittered, an iron concentration of <0.10 mgiL is anticipated for the treatment system
effluent. This will eliminate any water quality concern for iron as the projected iron
concentration in the stream will drop to 0.51 mg/L.
Lead
The highest reported lead concentration is 0.140 rng/L for well EW-4. This well
produced a water sample with a high amount (2,400 mg/L) of suspended ,solids and is
not considered a representative sample of treatment system effluent. The estimated

treatment system discharge lead concentration is 0.034 mg/L. The projected instream
Lead concentration is <0.0045 mg/L, which is well below the 0.025 mg/L standard.
Manganese
The estimated treatment system effluent concentration is 1.055 mg/L. The projected
instream concentration of manganese is 0.137 mg/L, which is below the standard of
0.200 mg/L.
2.3 Treatment System Usage
The treatment system will treat affected ground water, and HCC will be the sole user of the treatment
system. The IRA system has been sized to treat 80 gallons per minute on a continuous basis.
2.4 Project Approach
The treatment system described in this evaluation is an IRA system. Depending on the results of on-
going site investigations, additional Remedial Action System(s) may be constructed.
At present, future flow rates from additional ground water treatment systems cannot be estimated
because the nature and total extent of affected ground water at the site has not been determined.

Section 3
SYSTEM DISCHARGE ALTERNATIVES
The treated ground water discharge alternatives for the DRP site (sewer discharge, subsurface
discharge, and spray irrigation were evaluated. The following describes these alternatives.
MAY 994
SECTION 2
3.1 Connection to Sewerage System
The alternative of discharging treated ground water to a publicly owned treatment works (POTW) is
applicable to the treated ground water, provided that the quality of the water meets the pretreatment
requirements of the local regulatory agency. Dreyfus Research Park is served by the Charlotte -
Mecklenburg Utility Department (CMUD); however, CMUD is not issuing permits for ground water
disposal. Correspondence from CMUD documenting this decision is provided in Appendix ti,
3.2 Subsurface Disposal System
Two areas at the DRP facility were evaluated as potential sites for a subsurface disposal system;
An undeveloped area northwest of the campus (see Figure 1-1)
A meadow area southeast of the campus (see Figure 1-1)
Residential use of the land in the immediate vicinity of the plant does not make the purchasing of
adjacent land for a subsurface disposal system an option.
Subsurface investigations in the undeveloped area northwest of the campus are in progress. Initial
results indicate the presence of TCE- and PCE- affected ground water that can potentially migrate off -
site to adjacent residential areas. The addition of water through an infiltration gallery may mobilize the
ground water in the direction of the residential area.
Permeability tests in the meadow area indicate a soil permeability of 4 x 10 cmis ,which indicates that
the area may be suitable for an infiltration gallery. However, subsurface investigations in this area
indicate the presence of TCE- and PCE- affected ground water, and the addition of water through an
infiltration gallery may mobilize the ground water in the direction of little Sugar Creek.

RMT NPDES PERMIT APPLICATION MAY 1994
HOECHST CELANESE DREYFUS RESEARCH PARK SECTION 2
In addition, the meadow appears to be located in the flood plain of Little Sugar Creek, and periods of
an elevated water table would inhibit subsurface disposal of the treated ground water in this area.
3.3 Spray Irrigation System
The two areas evaluated in Section 3.2 were considered inappropria
the following reasons:
or a spray irrigation system for
The low permeability of the undeveloped area would tend to create excessive surface
runoff from a spray irrigation system, and ground water containing PCE and TCE may
be mobilized,
The meadow area contains PCE- and TCE- affected ground water that may increase
mobility if additional water were introduced from a spray irrigation system. Also,
periods of an elevated water table in the area would inhibit water infiltration from a
spray irrigation system.
A third option of using the plant's existing lawn sprinkler system as a spray irrigation system was
evaluated. This option was not considered feasible because of site controls and system down time
during wet weather months. If system operation was extended during periods of saturated soil
conditions, then excessive runoff from the sprinkler system would occur.
3.4 Feasibility of Discharge Alternatives
The information discussed in the previous sections shows that, due to site conditions and local POTW
policies, the evaluated discharge alternatives are not environmentally feasible. However, system
discharge to the Little Sugar Creek is environmentally feasible because of the creek's proximity to the
property and the quality of the treated ground water that would be discharged to the creek.

of a SUDP shouid 1I information regarding the site and project meet program requirements
The State wig be notified in writing by the CMUD-SPD when applications are once again
accepted from groundwater remediation sites. Those sites who submit a request for a SUDP for
a groundwater remeidiation project, will have their submittal returned to them along with a letter
stating that the CMUD-SPD is not accepting applications at the time. Therefore, those sites may
present you (the stkte) with the appropriate documentation so they may pursue Jther routes of

5.
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "'maximum daily discharge." This limitation is identified as 'Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part 1 of the pemiit,

Part II
Page 2 of 14
6. Concentration Measurement
a The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values), The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values), The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "'Weekly Average"' under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum." under "Other Limits" in Part I of the permit.
d. The "'average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as ''Annual Average" under "Other Limits" in Part 1 of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
considered to be the "daily average concentration" for the discharge. It is identified as "daily
average" in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "'Quarterly Average Limitation"' in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods: January through March,
April through June, July through September, and October through December.

Part II
Page 3 of 14
7. Ot er Measurements
a Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month.
b. An "'instantaneous flow measurement" is a measure of flow taken at the time of sampling, when
both the sample and flow will be representative of the total discharge.
c. A "'continuous flow measurement" is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. Types of Samples
a Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge
and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow
recorder and totalizer, and the present gallon interval between sample collection fixed at
no greater than 1/24 of the expected total daily flow at the treatment system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no

9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the nurnber of individual values,
. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the
individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one
(1).
Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows,

facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c, of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
Conditions necessary for a demonstration of upset.

E. 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 II989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 4.9c/0 (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 February, May, August and November. 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 -I (original.) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
.Environmental Management
1101 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
controi 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.

Dear Ms. Carter:
Our records indicate that NPDES Permit No. NO0084301 was
issued on September 4, 1996 for the discharge of wastewater to the
surface waters of the State from your facility. The purpose of
this letter is to advise you of the importance of the Permit and
the liabilities in the event of failure to comply with the terms
and conditions of the Permit. If you have not already done so, it
is suggested that you thoroughly read the Permit. Of particular
importance is Page 4.
Page 4 sets forth the effluent limitations and monitoring
requirements for your discharge. Your discharge must not exceed
any of the limitations set forth. The section headed "Monitoring
Requirements" describes the measurement frequencies, sample types
and sampling locations. Upon commencement of your discharge (or
operation), you must initiate the required monitoring. The
monitoring results must be entered on reporting forms furnished or
approved by this Agency. If you have not received these forms,
they should be arriving shortly. If you fail to receive the forms,
please contact this Office as quickly as possible. I have enclosed
a sample of the "Effluent" reporting form (DEM Form MR-1), plus
instructions for completing the form. It is imperative that all
applicable parts be completed, and the original and one copy be
submitted as required.
Please be advised, that an annual administering and compliance
monitoring fee may be required for your facility. You will soon be
receiving a statement from our Raleigh Office. It is imperative
that the fee be paid in a timely manner so as to prevent
enforcement action or possible revocation of your permit.
The remaining Parts of the Permit set forth definitions,
general conditions and special conditions applicable to the
operation of wastewater treatment facilities and/or discharge(s).

The conditions include special reporting requirements in the event
of noncompliance, bypasses, treatment unit/process failures, etc.
Also addressed are requirements for a certified wastewater
treatment plant operator if you are operating wastewater treatment
facilities. Any changes in operation of wastewater treatment
facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment
facilities must be permitted or approved by this Agency.
Failure to comply with the, terms and conditions of an NPDES
Permit subjects the Permittee to enforcement action pursuant to
Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $10,000 per violation (and/or criminal penalties)
may be assessed for such violations. If you find at any time that
you are unable to comply with the terms and conditions of the
Permit, you should contact this Office immediately. A Consent
Order may be necessary while pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a
five-year period. Permits are not automatically renewed. Renewal
requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of
your Permit. This date is set forth on Page 1 of the Permit. Also
note that NPDES Permits are not automatically transferable. If
you, as the Permittee, cease to need this Permit, then you should
request that the Permit be rescinded or transferred to another
party, if necessary.
As mentioned previously, the purpose of this letter is to
advise you of the importance of your NPDES Permit. Please read the
Permit and contact this Office at 704/663-1699 in Mooresville if
you have any questions or need clarification. We look forward to
providing any assistance.

5. Mass/Day Measurements
a. The "monthly average discharge" i defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled.
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit,
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday o Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. 1t is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part 1 of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "'Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sarnpled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

Part II

b. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliforrn bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as
"Daily Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily
discharges sampled and/or measured during such year (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day . The average yearly count for
fecal coliforrrt bacteria is the geometric mean of the counts for samples collected during a
calendar year. This limitation is identified as "Annual Average" under "Other Limits" in
Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount
of dissolved oxygen required to be available in the effluent prior to discharge averaged
over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the
sample is considered to be the "daily average concentration"' for the discharge. It is
identified as "daily average" in the text of Part I.
The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through. September, and October through December.

DECEMBER 1993
HOECHST CELANESE - DREYFUS RESEARCH PARK SECDON 1
Section 1
INTRODUCTION
Hoechst Celanese Corporation (HCC) voluntarily implemented investigations at the Dreyfus Research
Park (DRP) facility to identify and characterize the potential to which the environment may have been
affected by previous operations at the site. Following preliminary work at the site, HCC entered into an
Administrative Order on Consent (Consent Order) with the North Carolina Department of Environment,
Health, and Natural Resources (NC DEHNR) on May 14, 1992,
1.1 Background
The DRP Site consists of approximately 127 acres. The facility, which has been in operation since the
early 1950s, is a research and development operation for several HCC business units, including Textile
Fibers, Industrial Fibers, Polymer and Filter Products, and New Business Development. Figure 1-1
shows the site location.
Preliminary investigations to assess subsurface environmental conditions at the DRP Site were initiated
in November 1990. The results of these investigations led to a Remedial Investigation (RI), which
began in 1991 and was implemented in two phases, The results of the Phase 1 RI activities were used
to plan further investigations. In January 1993, HCC initiated the Phase 2 RI. The results of the Phase
1, Phase 2, and off -site investigations were reported to NC DEHNR on September 30, 1993.
The off -site investigations reveal that low levels of tetrachloroethylene (PCE) and trichloroethylene
(TCE) in a portion of the ground water have migrated beyond a portion of the DRP southern property
line. Although the community adjacent to the DRP facility does not use the ground water, HCC has
voluntarily initiated plans to implement an Interim Remedial Action (IRA) System primarily to reduce
further migration of affected ground water to off -site areas. HCC retained RMT, Inc, (RMT) to develop
an IRA strategy in conjunction with the completion of the Phase 2 RI,
In July 1993, on the basis of preliminary data indicating possible off -site contamination, RMT previewed
a basic IRA approach with NC DEHNR. In September 1993, HCC reviewed with the community the off -
site ground water conditions and the plans to implement an IRA System as soon as possible.

INTERN REMEDIAL ACTION DESIGN REPORT DECEMBER 1993
HOECHST CELANESE DREYFUS RESEARCH PARK SECTION 1
On September 29, 1993, an IRA Workplan was submitted to the Superfund section of NC DEHNR's
Division of Solid Waste Management and was approved on November 15, 1993, A copy of this
approval letter is provided in Appendix A. This workplan presented a conceptual and preliminary
design and an implementation plan for an IRA System. The IRA Workplan was also submitted to the
Charlotte -Mecklenburg Utilities Department (CMUD) on October 20, 1993, and was verbally approved
on November 16, 1993. Written confirmation of the CMUD approval is forthcoming. In accordance with
discussions with the NC DEHNR Permitting and Engineering Division, review of construction plans and
specifications described in this report and presented under separate cover can be initiated based on
these commitments,
1.2 Project Approach
The IRA System has been designed based on extracting ground water from key areas along the
southern property line, treating the extracted ground water and reusing the treated water primarily as
cooling water within the DRP facility. As a result, wastewater discharges to the CMUD sewer system
under Pretreatment Permit 0074, provided in Appendix B, will not be affected. The only change
resulting from this approach will be the decrease of city water currently used as cooling water,
1,3 Project Objectives
The objectives of this IRA are as follows:
Initiate as soon as possible a system to minimize further migration of affected ground
water to off -site areas.
Obtain site -specific data regarding aquifer hydraulic characteristics in order to develop
design criteria for additional ground water extraction that may be required for further
control of olf-site migration and for remediation of other on -site areas.
1.4 Report Objective
This report and the supporting plans and specifications present to the NC DEHNR Permitting and
Engineering Division the information required to apply for a Pretreatment Authorization to Construct
Permit. HCC's formal request for the construction and an $150 application fee are included as part of
the transmittal letter for this report.

HOECHST CELANESE - DREYFUS RESEARCH PARK SECT'ON 2
Section 2
PROCESS DESIGN
The IRA process design is based on the data obtained during the RI and RMT's experience with similar
remedial actions. The following sections present a technical basis for designing an IRA System.
2.1 Extraction Well Locations
Proposed extraction well locations for the IRA have been selected based on PCE and TCE
concentrations in ground water and subsurface geologic conditions along the southern property line, as
shown on Figures 2-1 and 2-2, respectively. Extraction wells for the IRA are proposed tor areas of the
aquifer that have PCE and TCE concentrations greater than 0.01 mglL in the ground water.
Preliminary capture -zone modeling indicates that the proposed interim extraction well operation will
intercept most of the ground water flow at the property line that migrates directly to off -site residential
areas.
2.2 Ground Water Extraction and Treatment
This section presents a description of the IRA ground water extraction and treatment system and a
summary of the process design basis,
2.2.1 System Description
The IRA System is based on a manifold jet pump system that has one return tank and one
recirculation pump. The return tank and recirculation pump serve multiple wells operating in
parallel via a pipeline manifold for the recirculation water, Figure 2-3 shows this approach on
the Process Flow Diagram.
Manifold jet pump wells will extract the ground water for the IRA, A jet pump is essentially a
combination nozzle and Venturi section that has no moving parts, Figure 2-4 shows the basic
jet pump assembly that will be positioned near the bottom of the extraction wells, When water
is circulated under pressure through the jet pump (Q,), a vacuum is created that induces
ground water trom the well (Q2), which becomes entrained in the circulation water (Q, + 102)
The combined flow (Q, + 02) is conveyed under pressure to an above -ground tank, also called
a return tank, and water from the return tank is recirculated (Q,) to the jet pump assembly using
a constant rate centrifugal pump. This is a continuous process, and the overflow from the

2.2.2 Operations Contingencies
Because all mechanical aspects of the manifold jet pump extraction system will be centrally
located in an enclosed building, the controls required to accommodate atypical operating
conditions can be readily implemented. An auto -dialer will transfer alarm conditions to three
locations within the DRP facility, Control designs for operational contingencies will include the
following:
If either the air stripper blower or lift pump shut down, the extraction system
recirculation pumps will automatically shut down and an alarm indicator will be
activated.
A spare, in -place lift pump and a bag filter will be available.
If either or both of the recirculation pumps shut down, an alarm indicator will be
activated. The air stripper blower may not be automatically shut down during
this event,.
If a high-pressure condition ever occurs in the bag filters, the extraction system
will shut down.
If high levels ever occur simultaneously in the elevated nonpotable water
storage tank and one of the wastewater equalization tanks, the IRA System wi
automatically shut dawn.
Appendix D presents a detailed Controls Narrative, which should be reviewed in conjunction
with the Process and Instrumentation Diagram (Drawing No. 91510-101).
2.3 Process Design Basis
This section summarizes the basis used for ground water extraction rates and water treatment design.
2.3.1 Ground Water Extraction Rates
Based on available hydraulic conductivity data and in conjunction with RMT's experience with
ground water extraction in aquifers of similar characteristics as DRP, RMTs Hydrogeology
Department has projected extraction rates. A 30 percent contingency has been applied to
these projected rates for the IRA design basis, Table 2-1 summarizes the ground water
extraction rates.

In summary, 32 and 42 gpm are the design extraction rates for the interim jet pump systems. However,
the manifold pipeline has been designed to allow for potential future expansions to these systems. The
design allows for four extraction wells to be added to each jet pump system at the maximum single -well
design extraction rate of the respective system. Table 2-2 summarizes the design flow rate basis for
the manifold pipeline design,

Carbonair Environmental Services wil provide the low profile air stripper. Appendix E provides
a summary of Carbonair's air stripper modeling results. A five -tray, low profile air stripper has
been recommended based on the modelings. HCC plans to purchase a six -tray, low profile air
stripper. Appendix F provides the equipment specifications for this air stripper system,
including its associated vapor -phase carbon vessels. Appendix G provides other major
equipment specifications, such as recirculation pumps, return tank, jet pumps, return tank
overflow flume, treated water transfer pumps, and bag filters.
Based on monitoring well data, calcium and magnesium levels in the extracted ground water
are projected to be low (< 30 mgfL), and iron levels are projected to be low (< 0.3 mg(L).
Furthermore, all inorganics in the extracted ground water are projected to be below North
Carolina Water Quality Standards. A bag fitter system using 10-micron mesh filter bags has
been included in the IRA design as a precaution to remove low levels of solids that may be in
the treated water before the water is transferred to the water reuse system. A detailed
evaluation of inorganics in the extracted ground water will be performed after the installation
and development of the extraction wells, and then throughout the interim operations.
2.4 Water Discharge Permitting
A key factor for implementing a proactive IRA System is obtaining approval to discharge the treated
ground water. Although a sewer discharge is readily available at the DRP facility, CMUD has
temporarily stopped accepting Special Use Discharge Permit (SUDP) applications for ground water
remediation sites due to the priority of first issuing Significant Industrial User Permits. This is described
in a March 8, 1993, CMUD letter, which is provided in Appendix H. The following excerpt from the
March 8, 1993, CMUD letter should be noted,
The CMUD-SPD is aware that due to particular site circumstances and/or other
controlling factors, that the only environmentally sound option may be to discharge to
the POTW. At the state's request, the CMUD-SPD will review such special cases and
work toward timely issuance of a SUDP should all information regarding the site and
project meet program requirements.
HCC is currently preparing an NPDES permit application to allow the discharge of treated ground water
to Little Sugar Creek, However, an NPDES permit requires 9 to 12 months to obtain, which is beyond
lAWR9',.9%506 E061calg3
2-14

INTERIM REMEDIAL ACTION DESIGN REPORT DECEMBER 1993
HOECHST CELANESE - DREYFUS RESEARCH PARK SECTION 2
the scope of the IRA schedule objectives. Therefore, in the interim period, all the treated ground water
will be reused so that DRP facility wastewater discharges to the CMUD sewer system will not change
and compliance with OAP's current pretreatment permit will be maintained.
It is important to start up the IRA System so that the effectiveness of controlling the off -site migration of
affected ground water can be evaluated as soon as possible. This evaluation will provide the data
needed to design supplements for the IRA System, if required. When operating the IRA System, HCC
has the flexibility of operating only select extraction wells in order to evaluate aquifer drawdown
characteristics. Therefore, the IRA System can be operated in the interim at low extraction rates, In
any event, all the treated ground water will be reused. An NPDES Permit would be used later for long-
term remedial action operations.
RMT and Robert L. Griffin, the CMUD System Protection Manager, have previewed the need to
discharge treated ground water to the sewer on an interim basis. CMUD requested a report describing
the IRA approach, including a technical evaluation of how the current pretreatment would be affected.
On October 20, 1993, RMT submitted the IRA Workplan to CMUD. The transmittal letter for this
workplan is presented in Appendix I. CMUD has acknowledged the viability of this IRA approach and is
planning to issue a written statement of acknowledgement and approval,
2.5 Air Emission Permitting
The DRP facility is located in Mecklenburg County. Since Mecklenburg County is in nonattainment for
ozone, requirements for pollution control and permitting are more restrictive than for a county in
attainment for ozone. Sources of VOCs in nonattainment areas are normally required to apply for
construction and operating permits. In addition, these sources may be required to be controlled with
pollution control devices.
The emissions of VOCs in a from the air stripper during IRA operations will be minimal (< 100
pounds/year), which normally means that the air stripper must be registered, but not permitted, before
construction in accordance with the North Carolina Administrative Code, Chapter 2 - Environmental
Management, Subchapter 2D - Air Pollution Control Requirements, Section 0.202 - Registration of Air
Pollution Sources, Subsection (b). However, the Mecklenburg County Department of Environmental
Protection (MCDEP) has recently decided to require all sources of emissions, independent of their

amounts, to follow the formal permitting procedures. RMT has initiated coordination with Mr. Joseph
Hack of M DEP for filing a permit application. However, due to the low VOC emission rate, and the
fact that the two activated carbon vessels in series will rer eve 9 9 percent of the VOC emissions, a
formal MDE.P Construction Permit is not expected to be required.
The State also enforces Subchapter 2D - Air Potiution Control Requirements, Section 0.0518 -
Miscellaneous Volatile Organic Compound Emissions, Subsection (d) which allows up to 40 pounds o
VOC emissions per day (24 hours) from each site. The estimated maximum VOC emission rate from
the air stripper is 0,2 Ida/day,

PLANS AND SPECIFICATIONS
This section describes the construction plans and specifications for the ground water extraction and
treatment systems.
3.1 Extraction Wells
The proposed interim ground water extraction wells will be installed under a well installation permit,
independent of the Pretreatment Authorization to Construct Permit. In addition, the NC DEHNR
Division of Solid Waste Management has approved the proposed well installations. The extraction
wells will primarily comprise a 6-inch diameter PVC well casing and screen. The top of the extraction
wells will be enclosed below grade in a traffic -rated vault. A 2-inch screened PVC pipe will be mounted
inside each extraction well and will extend the entire depth of the well to allow the use of a water level
indicator and bailer without any interference from the jet pump assembly and piping.
3.2 Ground Water Extraction and Treatment System
Table 3-1 summarizes the content of a package of construction plans and specifications that is being
submitted under separate cover to the NC DEHNR Permitting and Engineering Division. The IRA
System design is based on housing all major equipment and controls in one building. Electrical power
is only required for the equipment inside the building. No power and controls are required at the
extraction wells.
Outside the building, all piping and conduits are designed to be installed below grade. Since the
pump/control building will be located across a main facility access road from the extraction wells, the
manifold pipelines will have to be jacked and bored beneath the road. The transfer of treated ground
water to the elevated nonpotable water storage tank will tie in to an existing 4-inch pipeline. The
control building will be heated and insulated so that above -grade piping within the building will be
protected from freezing.
Instrument specifications are provided in Appendix J. Standard construction specifications that will be
integrated into a construction contract are listed in Table 3-2.

PERFORMANCE MONITORING AND EVALUATION
Since a primary objective of the IRA is to accomplish effective control of certain ground water
conditions as soon as possible, it is important to monitor system effectiveness. This section describes
a plan to monitor the short-term and long-term effectiveness of the proposed IRA. A more detailed plan
was submitted to the NC DEHNR Superfund section on December 15, 1993. The monitoring results
will be frequently reported to NC DEHNR and the community around the DRP facility. Also, any actions
that may be taken based on the monitoring results will be reported,
4.1 Ground Water Extraction Effectiveness
Monitoring of the IRA System start-up and operation will be accomplished through various data
collection tasks. The data collection tasks include those conducted on a one-time basis during system
start-up and those conducted at a specified frequency during system operation. Two aquifer tests will
be conducted prior to system start-up, one at well EQ-2 and one at well EW-10. Each aquifer test will
include a minimum 24-hour pumping phase followed by a 12-hour recovery phase. Aquifer tests and
step-drawdown tests will be conducted with the IRA System start-up. Step-drawdown tests will be
conducted on wells EW-4 and EW-13 before start-up of the IRA System.
4.2 Ground Water Treatment Efficiency
Air stripper influent and effluent samples will be collected daily during the first week after start-up.
Quick turnaround of analytical results for PCE and TCE will be obtained in order to confirm the
efficiency of the air stripper. After the required efficiency is confirmed, air stripper influent and effluent
samples will be collected weekly and analyzed for PCE and TCE, This monitoring plan will be re-
evaluated after 3 months of operation.
Additional sampling and analyses will be performed on the treated ground water as required for water
reuse applications. Routine combined wastewater sewer discharge samples will also be analyzed for
PCE and TCE to confirm that those constituents are not detected in the sewer discharge.

Subject: Performance eat Carbonair STAT low profcle air stripper.
Fred has bought several pieces of equipment from Carbonair and thinks they are very good, while being much lower
priced than Shallow Tray. He bought a STAT 80 for ground water remediation about one year ago. It met
performance specification. They have cleaned it once in the past year. Cleaning it was no big deal. They gravity
drain into a larger sump before pumping the treated ground water.
The only problem he ever had with the STAT 80 was that sometimes water would splash up on the high level switch
and trip the system off. AMT installed an internal baffle to solve this problem. He believes that Carbonair has begun
using a better quality level sensor since then.

Subject: Performance of Carboriair STAT low profile ripper.
RTRS was listed by Carbonair as a reference for their STAT system. I obtained the following information:
Application: Air stripping of volatiles from gasoline impacted ground water. They have bought 8 air strippers in the
past 8 months.
Performance: As good as Shallow Tray but at a lower price. Good materials of construction have made for good
reliability (so far).
Sump: They use the small integral sump in the air stripper by throttling the discharge pump until its flow just
exceeds the inlet flow. This prevents excessive cycling.
Fe/Mn: They do have an iron problem at some sites, but it has not caused fouling of the air stripper; rather, it
fouls the activated carbon used for polishing. They have sotved this problem by adding a secret
stabilizer (perhaps a polyphosphate) before the air stripper to keep the iron in solution until it gets
past the carbon.

Subject: PerformancePertormance of Carbonair STAT low profile air stripper.
Application: They used a small rental STAT for a pilot unit. They were air stripping volatiles from contaminated
ground water at the Kiefer Landfill. Their flowrate was about 40-60 gpm. They had little iron and
scaling was not a problem.
Performance: They had no trouble with the air stripper during its three months of operation. The standard package
served as it was intended. Vicki stated that Carbonair gave excellent service and that they are using
them as the air stripper supplier in the final design. They are switching to a packed tower, however,
because Carbonair does not have a single STAT unit that can handle the expected 1200 gpm.
Sump: They elevated the air stripper so that they could gravity drain to a 1,000 gallon plastic tank. They
used the tank for pump suction.

IV. Lift Pump System
Treated ground water gravity flows from the air stripper to
the lift station clear well through a magnetic flow meter,
FE-301. Flow transmitter FIT-301 transmits the flow signal
to the control panel CP1 where flow totalizer FQI-301
continously totalized the flow and a circular chart recorder
FIR-301 continously record the flow.
When flow out of the air stripper is low, FSL-301 will
energize and alarm FAL-301 on CP1.
The lift pump system consists of a lift station clearwell,
two lift pumps and two bag filters.
The lift station clearwell has level switches LSLL-500, LSL-
500, LSH-500 and LSHH-500 , that are interlocked with the
lift station pumps P-3 and P-4, the air stripper blower B-1,
and the recirculation pumps P-1 and P-2.
Lift pumps P-3 and P-4 pumps liquid from the clear well to a
bag filter system.
Motor alarm MA-501 is
pump P-3 is running.
Motor alarm MA-502 is

Pumps P-3 and P-4 are operated by a Hand -Off -Auto handswitch
HS-501 and HS-502 respectively.
When high level in clear well is reached, LSH-500 will start
lift pumps P-3 or P-4 if HS-501 or HS-502, respectively, is
in the auto position.
When low level in clear well is reached, LSL-500 will shut
down lift pumps P-3 or P-4 if HS-501 or HS-502,
respectively, is in the auto position.
When low low level in clear well is reached, LSLL-500 will

IV. Lift P np Slist (continued)
When high high level in clear well is reached, LSHH -00 will
alarm R 00 on CP1 and shut down recirculation pumps p-1
and P-2, air heater and blower B-1 if HS-100 or H5- 00 or
H405 or H-400, respectively, is in the auto position.
P-3 P-4 runs anytime H - 01 or H - 502, respectively, is
in the Hand position.
A pressure indicator PI-503 is installed to measure the
discharge pressure of the lift stations pumps P-3 and P4.
A high differential pressure switch dPSH 505 installed
across the two bag filters. Each hag filter can be manually
isolated with two butterfly valves to allow on-line bag
changeout.
When high differential pressure across the two bag filters
is reached, dP 505 will alarm dP 505 on CP1 and shuts
down recirculation pumps P1 and P-, air heater, blower B-1
and the lift stations pumps P2 and P-4 if 100 or H - 00
or HS-405 or HS-400 or IDS-501 or HS-502, respectively, is in
the auto position.
Pressure relief valv PBV-504 opens when normal operating
pressure is exceeded, which will recycle the flow to the
lift station clear ell.

V. Treated Water Storage Tank Overflow
Treated water from the lift station will be pumped into an
existing elevated storage via a three way flow control valve
FCV-605.
Level in the existing elevated storage tank is measured with.
a pressure switch, PSH-601, set at 98000 gallons.
Level in the existing equalizations tanks #1 and #2 are
measured with level swithes LSH-602 and LSH-603,
respectively.
Flow control valve FCV-605 normally opens to allow treated
ground water to flow to the elevated storage tank. However,
if PSH-601 senses high level in the elevated storage tank,
FCV-605 changes flow direction to divert the treated ground
water to the sewer. FCV-605 must fail in the position that
allows flow to the elevated storage tank.
The diverted treated ground water flow from the clear well
to the sewer line will be measured with a flow meter FE-600
and totalizer FQI-600. FQI-600 indicates the amount of
water that is not reused.
PSH-601 and LSH-602 or LSH-603 shut down recirculation pumps
P-1 and P-2 in the automatic mode.
Pressure indicator PI-604 indicates the pressure of the
diverted flow to the sewer.
Pressure indicator PI-606 indicates the pressure of the
pumped flow to the elevated storage tank.

Re: Proposal Number: 203455-A
Project Name: Hoechst Celanese Project
Location:
Dear Sirs:
Carbonair is pleased to quote products and services for the referenced project, it will
contain Information that has been spelled out In our phone conversations. Upon completion
of your final bid specifications for all of the equipment in Carbonalrs' scope of work, a final
proposal with firm pricing will be submitted for approval. it is our understanding that a
purchase order will be issued by Hoechst Celanese with the stipulation that the final contract
purchase price may/wili be increased because of the increased scope of work. Detailed
product specifications are attached.
Executive Summary
The present scope of work that we have discussed previously will be include providing a
Carbonair model STAT 80 low profile airstripper with 6 aeration trays. The STAT unit will
be operated at 70 gpm and an air flow rate of 300 cfm to reduce the critical compound,
tetrachloroethene, from an influent concentration of 275 ppb to <1 ppb. The STAT unit will
include a sump with high level alarm switch, low blower pressure swatch, high pressure
alarm switch, pressure gauge, and a blower with 10 horsepower, 230/460 volt, 3 phase,
TEFC motor, and a gravity discharge system..
A process air heater is recommended and will be provided with the system. The heater will
increase the temperature of the airstream after the STAT unit to 90-95 degrees F and will
reduce the relative humidity to approximately 50% which will optimize the performance of
the carbon.
The STAT 80 and process air heater will be mounted on a common skid with the ducting
from the airstripper effluent flange to the inlet of the heater prepiped. The instrumentation
described above will be located on the skid as well. Wiring in the field will be required to
the blower motor, pressure switches, and high level alarm switches on the skid to the
control panel by a local contractor, assuming the control panel will be located away from the
equipment.
For the treatment of the contarniroeated vapors In the airstream, we recommend using two (2)
GPC 12 vapor phase carbon adsorbers, each Loaded with 1,500 pounds of react 4x10
carbon. Included with each vessel will be sample ports on the influent and effluent of each
unit. Transition pieces with quick connect fittings will be included with each unit. Flexible
ducting will be provided for connection to the effluent flange of the process air heater to the
Influent of the Lead vessel in series, from the effluent of the lead vessel to the Influent of the
lag (second vessel), and from the effluent of the second vessel to the off -gas exhaust
ducting provided by RMT. Each GPC 12 is skid mounted and forklift accessible for ease of
moving them around during a carbon exchange.

STAT Series
Sieve Tray Aeration Technology
Carbonair's exclusive STAT series represents the
best choice for low profile air strippers with design
simplicity, flexibility and high performance.
In Carbonair's STAT units, the water and air are
contacted in step -wise fashion on multiple trays. The
water enters at the top and flows across each tray. The
air passes upwards through openings in the trays, then
bubbles through the water to form "a surface of foam°'
which provides extreme turbulence and excellent
volatilization. Since the water in Carbonair's STAT
units flows horizontally across each tray, the traveling
path length of water and the required removal efficiency
can be achieved by increasing both, the number and
length of the trays. Therefore, the STAT units provide
much lower tower height than the conventional
packed towers.
Another advantage of Carbonair's STAT units is
that air and blower power consumption are effectively
utilized since a single air stream passes through every
tray before exiting the tower. As a result of minimal
air flows, the organic contaminants are concentrated
and effectively removed by vapor phase carbon.
Low tower height yields numer-
ous other advantages: rapid installation,
easy winterization, inconspicuous
appearance, easy shipping and easy
maintenance. The STAT unit also re-
duces the potential for fouling since it
contains no packing media and provides
an extreme turbulent condition.
Carbonair's STAT units are avail-
able with a number of plate configura-
tions, blowers and controls, and can
achieve removal efficiency up to 99.99%.
OPTIONS
Explosion -proof controls.
Discharge pump.
Well control.
Off -gas carbon.
Humidity control.
Carbon polish.
Winterized enclosure.
FEATURES
The low air flow and minimal tower height
make the unit ideal for off -gas treatment.
The compact unit can be installed in a few
hours.
Controls include motor starter, level switch,
air pressure gauge and air pressure switch.
Panel comes with blower, manual -off -
automatic switch and alarm lights.
Computer modeling customizes the system
for optimum air flow, number and size
of trays.

GPC gas phase carbon adsorbers are designed
to provide efficient, economical means to control
odor, toxic vapors and corrosive gases. Several
types of activated carbons are available for a variety
of applications. Untreated activated carbons remove
organic toxic gases such as trichloroethene, perchloro-
ethene, benzene, toluene, ethylbenzene, xylenes and
hydrocarbons. Chemically treated activated carbons
remove specific gases such as hydrogen sulfide,
sulfur dioxide, nitrogen oxides, halogens, mercury,
aldehydes and mercaptans.
Specifications for each model are listed on
reverse side.
GPC 3 is ideal for controlling toxic vapor and
corrosive gas vented from sources of small volume
emission (storage tanks, reactor vessels, sewage
treatment plants).
GPC 4 is designed specifically to control toxic
vapor and corrosive gas vented from storage tanks,
reactor vessels, sewage treatment plants and other
sources of small volume emission. Welded steel
construction provides exceptional strength and
durability. The unit is forklift compatible for trouble -
free transportation and quick installation. Interior
is double -coated with a corrosion -resistant epoxy
polyamide, ideal for the corrosive and abrasive condi-
GPC 48
tions of gas phase service. Suitable for
any gas phase application, including air
stripper and soil venting off -gas
treatment.
GPC 12, GPC 20 and GPC 48's
welded steel construction provides
exceptional strength and durability
while the skid mounting and forklift
compatibility make transportation and
installation quick and trouble free.
Interior is double coated with a
corrosive -resistant epoxy polyarnide,
ideal for the corrosive and abrasive
conditions of gas phase service. Suit-
able for any gas phase application,
including air stripper and soil
venting off -gas treatment.
GPC 70 and GPC 120 are
among the largest gas phase carbon
adsorbers available. Welded steel con-
struction provides exceptional strength
and durability, while the integrated
lifting eyes and roll -off truck feature
make transportation and installation
quick and trouble free. Interior is
double coated with a corrosion
resistant epoxy polyamide, ideal for

The CMUD-3PD will be permitting the sites 1.- 4. above by August 1, 1993. The others
may be permitted at some time by this division but there is no guarantee, should a permit be
issued, that it will be in 1993.
The CMUD-9-'0 is aware that due to particular site circumstances and/or (miler controlling
factors, that the orily environmentally sound option may be to discharge to the POTVv. A: the
state's request, the.,-,MUD-SPD will review such special cases and work toward timely isz;uance
of a SUDP should 11 information regarding the site and project meet program requirements,
The State vvill be notified in writing by the CMUD-SPD when applications are once again
accepted from groundvvater remediation sites. Those sites who submit a request for a SUDP for
a groundwater remetiation project, will have their submittal returned to them along with a letter
stating that the CMUD-SPD is not accepting applications at the time. Therefore, those sites may
present you (the stete) with the appropriate documentation so they may pursue ther routes of
discharge.
Any question o regarding the contents of this letter should be addressed to Cathy K. Malast
or Robert L. Griffin et 394-9284, exts. 121 (CKM) and 132 (RLG).

Subject: Interim Ground Water Remedial Action Workplan
Hoechst Celanese - Dreyfus Research Park
Dear Bob:
I appreciate your reviews of sewer discharge options related to interim ground water measures planned
for the Hoechst Celanese Dreyfus Research Park. As you requested, enclosed is a copy of the report
entitled Interim Remedial Action Workplan, which was submitted to NC DEHNR on September 29,
1993. Also enclosed is the report transmittal letter to NC DEHNR. This report presents the
background for this project, which defines the need for the proactive remedial actions. This report also
presents the design basis and implementation plans for the project.
The report sections most pertinent for your review include the following:
• Section 1 summarizing project background, approach, and objectives.
Figure 2-1 noting the extent of impacted ground water to off -site areas, which is the
reason for the need to expedite interim remedial actions.
• Section 2.3 which summarizes Hoechst Celanese and RMT's understanding of CMUD
priorities.
Figures 2-4 and 2-5 which are facility water balance diagrams showing the feasibility for
re -using treated ground water, instead of city water, such that current sewer discharge
loadings are not impacted.
Drawing 5 is the preliminary Process Flow Diagram showing how the treated ground
water will be integrated into the facility water re -use system and ultimate discharge to
the sewer.
Section 4.2 which presents plans to perform monitoring to document that the sewer
discharge permit is not impacted.
Section 5 and Drawing 9 presents the proposed schedule for expediting the project.

Other aspects of this project
e
highlighted are as follows:
The interim remedial actions are temporary. Hoechst Celanese is evaluating options for
the long-term discharge of treated ground water, including NPDES discharge to little
Sugar Creek and ND (Non -Discharge) Permit for discharging the water to an infiltration
gallery and/or for use as irrigation water.
The extracted ground water will be treated to below North Carolina MCL levels, such
that the sewer discharge permit will not be impacted. Metal levels that are naturally
present in the ground water are well below sewer discharge Omits.
During interim operations, Hoechst Celanese has the flexibility to decrease the ground
water extraction rates, If required to comply with the sewer discharge permit. Since the
re -use of all the treated ground water is planned, this action is not anticipated.
In a couple of weeks, Hoechst Celanese will be submitting construction plans and
specifications to NC DEHNR in order to obtain a Pretreatment Authorization to
Construct Permit. To expedite the permitting process, NC DEHNR has agreed to
initiate their review of the construction documents without documentation of an
approved water discharge option. In order to finally receive an NC DEHNR
Construction Permit, a letter from CMUD is required, acknowledging the water re -use
and sewer discharge plan.
Hoechst Celanese and RMT have considered all practical options for handling the
discharge of treated ground waters, including my evaluation with you regarding General
Permits.
Bob, I hope this letter and workplan facilitates your consideration of this project. We certainly
appreciate your work schedule. Please do not hesitate to call me, or Pem Carter of Hoechst Celanese,
if there are any questions or comments. We look forward to hearing from you.
Sincerely,

Subject; Interim Remedial Action Workpian
Hoechst Celanese - Dreyfus Research Park
Dear Tom;
Enclosed are three copies of the Interim Remedial Action Workplan for the Hoechst Celanese Dreyfus
Research Park facility. The Workplan presents a Preliminary Design and a Workplan to finalize the
design to extract ground water from key areas along the southern property 'line, as RMT previewed with
you on July 20, 1993 and September 3, 1993. The proposed locations of interim ground water
extraction wefts are based on the Integration of available data related to ground water quality,
subsurface geology, and preliminary ground water capture zone analyses.
The objectives of Interim Remedial Action are to initiate, as soon as passible, a system to minimize
further migration of effected ground water to off -site areas, and to obtain specific design criteria that will
be important for additional ground water remedial actions that may be required later. We appreciate
you prioritizing your review of this Workplan and look forward to hearing from you.
Sincerely,
RMT, Inc.

and linear design techniques used provide a means for reliable
interface, circuit protection and excellent noise immunity.
Deedication of a eingfe custom IC per point eliminates the mu/11point
failure possibility present with common logic point cards. Even with
twinpoint logic cards, dedicated IC logic per point is used to isolate
point monitoring function*.
In addition to the nine standard operational sequences described on
Pga, 14 and 1i, the IC can be custom programmed to provide many
other sequence variations which enhance system performance by
supplying additional information,.
Some of the multiple options available by customizing the IC card
include integral auxiliary relays; optical isolation for AC or DC Inputs
and output switching; field voltage disconnect upon card removal; card
•talus indicator; relay lockout on test; transistor switch output for
computer or PC interfaces; rehash; slave lamp output for remote
indication; and orveff indication for status applications, Meny of these

DR 4500 Truline
Circular Chart Recorder
Function
Honeywell's Truline recorder is a one to
four -channel microprocessor -based,
ircular chart recorder, fts "one -pen'
stylus printhead produces up to four
analog traces and prints alphanumeric
chart data on a blank heat -sensitive
chart. All four traces share the same
Time line reference which the Truline
prints. This eliminates the error caused
by pen alignment offsets in
onventional pen designs, Since the
Truline prints the chart and generates
he analog traces at the same time,
there is no error due to variations in
chart size caused by changes in
temperature and humidity,
With microprocessor electronics and
single printhead, the Trufine recorder is
easily configured by users to meet a
variety of application requirements —
from metals to food processing In
addition to printing informative, accurate
chart records, the Truline recorder
alternately displays process variable
values for all channels in the selected
engineering units.
Models with up to four input channels
accept inputs from any one of a variety
of sensors or transmitters within the
onfigurable range limits.. Also, models
re available with one or two
ependent digital controllers to
enerate controlled output signals to
operate valves, dampers, heating
elements, etc. for process control.
Features
User configurable means the users
can set and/or alter operating
parameters to fit their requirements
including type of input without
recalibratron
Engfish language prompts coupled
with simple keystroke sequences
. make configuring the recorder easy
and straightforward.
Comprehensive operator interface
includes clear, brilliant alphanumeric
displays, indicators. deviation
ba►graph, and keypad for visual and
tactile interaction.
One all-purpose blank chart
eliminates the need for ordering and
stocking several types of charts.
And, users can design the chart to
match their specific application,
44-45.03-08

Specification
Figure t -- 'Twine recorder provides printed cf►an data and continuous digital
indication of process variable value
Up to four channels for monitoring
process variables from a variety
of sensor types helps reduce
panel space requirements.
`One -pen" printer prints
configurable alphanumeric chart
data including time and trend
lines. This automatically
compensates for chart width
variations caused by changes in
the ambient relative humidity.
Real-time, clock, dates time of
printing (hour, minutes, date and
year) and any operator changes
in real time to guard against
unauthorized chart advancement.
Up to two versatile PID digital
controllers let users configure the
exact control action needed for
their process.
A single set point ramp is user
programmable and it is easily
repeated and activated through
the Run/Hold key.
Up to six integral 'soft' alarms
are easily set by users to
announce selected, out -of -
limit conditions.
Optional DMCS communication
card supports bi-directional
communication link between the
recorder and hest computer.
er Configurable
the DR 4500 Series recorder,
croprocessor control replaces
onventional electro-mechanical
^ceding techniques. This means
at the recorder's capabilities are
primarily determined by its
are, Since Honeywell has
C-103

°programmed a variety of functional
capabilities into the recorder, a user
only has to conf u►e those functions
that are specifi cor t given
application. The user configures the
recorder by following English Language
prompts in the digital displays.
The configuration data (type of input,
chart speed, chart range, alarm settings,
tuning constants, etc) are stored in
nonvolatile memory for safe keeping in
the event of a power failure.
Operator interface
Two digital displays present the
process variable (PV) value and by key
selection, the controller set point;
controller output; deviation from
eterence input; dry bulb temperature;
otalization value, or engineering units
desired. In configuration mode,
digital displays are pre-empted by
English language prompts and values
for entering configuration data.
Indicators fight to show alarm condition,
which channel PV is on display, use of
remote set point, which output relay is
on, selected temperature unit, and
controller's mode of operation.
Deviation bargraph lets operators tell at
a glance if the process variable is at,
above, or below the controller's set
point.
The keypad through which configuration
data is entered also serves as an.
integral automaticlmanual station that
provides bumpless transfer for
controllers.
Microprocessor Contrrolled!
Recording and Printing
Both the chart and the printhead are
driven by stepper motors controlled by
the microprocessor for precise
maintenance free operation,
Since chart speed is configurable, users
can easily alter the chart speed through
the keypad - gear changing or
additional motors are no longer
equired.
The microprocessor uses the
onfigured chart range data as well as
the input data to determine the proper
inthead position. The stepper motor
urately positions the printhead drive.
y using a 'one -pen- printhead that is
capable of printing alphanumeric
characters, users can now set various
'printed' chart data through
configuration, This means that such
chart data as range marking in
engineering units, digital values for
process variables, and trace
identification are easily personalized for
the application. This data plus printed
time lines and engineering units of
ale eliminate the need to maintain an
inventory of a variety of preprinted
charts.
The Truline recorder uses a dot fill
echnique from a microprocessor
algorithm to produce a continuous
analog trace of a process variable.
C-104
Tirnellate
An integral real-time clock provides
accurate timing for the recorder's
time and date printing. A 10-year
battery backup assures correct
trig even when power fails.
put Processing
The input can be one of many
ndard tow -level electrical
signals. Since inputs are isolated,
users can connect different types of
input signals to multi -channel
models in any combination. And, for
models with 2 or more channels, a
relative humidity (wet/dry bulb)
actuation is available using 100 ohm
platinum bulbs (a 0,00385). The
input type and range are user
configurable for hassle free actuation
changes in the field. Ranges are
easily expanded and' compressed
within their span limitations to meet.
specific measurement needs. Users
can select upscale or downscale
sensor break protection for many of
the actuations.
Each input is sampled at a rate of 3
times per second for 1 or 2 inputs,
3times in2seconds for 3or4
inputs. Each sample is amplified and
then converted to a digital signal
hich is isolated and passed to the
tbcroprocessor. A digital fitter with
configurable time constants lets
users apply input signal smoothing
as desired All non -linear inputs
are linearized by the
microprocessor.
An integral 24 Vdc power supply
long with 4.20 mA input
onfiguration allows direct operation
th up to two transmitters without
need for any additional/external
smitter power supply.
To totalize a variable, such as a
flow signal, users select the
applicable input and set the digital
display scaling factor through
configuration. This eliminates the
need for additional integration
hardware including a mechanical
counter. The totalizer has an eight
digit display and 14 digit printing
on the chart.
Digital Controller
The DR 4500 Series recorder
controller includes an integral
microprocessor -based, single -
loop. PID controller, A variety of
output types, including a duplex
variation for heat -cool
applications, lets users select the
output that is right for their final
control element, Depending on the
output type users can configure the
control action as on -off, PID-A,
PID-B, PD with manual reset, or 3
position step control, As with the
record functions, English language
prompts quickly guide users
through the entry of all the
controller's configurable
parameters.
Diagnostics
All DR 4500 Series recorders
include self -diagnostic systems
that check critical operations and
provide error messages to alert
users about detected faults.
Power -up self -diagnostics is a
microprocessor controlled
diagnostic program that runs tests
on selected circuitry when the
recorder is powered up.
A 'key- test allows a user to
initiate on demand a self -
diagnostic routine that checks the
keypad and front panel displays.
