Subject: Permit No., NC0004952
Authorization to Construct
Emergency Hold Tank
Wastewater Treatment Facility
Cleveland County
A letter of request for an Authorization to Construct was received October 15, 1993 by the Division
and final plans and specifications for the subject project have been reviewed and found to be satisfactory.
Authorization is hereby granted to modify the existing treatment system by the addition of. an- emergency
hold tank with dimensions of 47 feet diameter and 40 feet height with centrifugal solids handling pumps
for transfer of influent and all the necessary piping, valves and appurtenances needed for proper operation
with discharge of treated wastewater into Buffalo Creek in the Broad River Basin. .
This Authorization to Construct is issued in accordance with Part III, Paragraph A of NPDES
Permit No. NC0004952 issued February 19, 1993, and shall be subject to revocation unless the
wastewater treatment facilities are constructed in accordance with the conditions and limitations specified in
Permit No. NC0004952.
The sludge generated from these treatment facilities must be disposed of in accordance with G.S.
143-215.1 and in a manner approved by the North Carolina Division of Environmental Management.
In the event that the facilities fail to perform satisfactorily, including the creation of nuisance
conditions, the Permittee shall take immediate corrective action, including those as may be required by this
Division, such as the construction of additional or replacement wastewater treatment or disposal facilities.
The Mooresville Regional Office, telephone number 704-663-1699, shall be notified at least forty-
eight (48) hours in advance of operation of the installed facilities so that an in -place inspection can be
made. Such notification to the regional supervisor shall be made during the normal office hours from 8:00
a.m. until 5:00 p.m. on Monday through Friday, excluding State Holidays.
Upon completion of construction and prior to operation of this permitted facility, a certification
must be received from a professional engineer certifying that the permitted facility has been installed in
accordance with the NPDES Permit, this Authorization to Construct and the approved plans and
specifications. Mail the Certification to the Permits and Engineering Unit, P.O. Box 29535, Raleigh, NC
27626-0535.

MEMORANDUM TO: Coleen H. Sullins
FROM: D. Rex Gleason
PREPARED BY: G. T. Chen
SUBJECT: Request for Permit Modification.
Addition of 30,000 GPD of Contaminated Groundwater
Hoechst Celanese Corporation
NPDES Permit No. NC0004952
Cleveland County, NC
Hoechst Celanese Corporation was issued an NPDES Discharge
Permit (No. NC0004952) for the operation of a 0.85 MGD activated
sludge wastewater treatment facility at its Shelby Plant. The
wasteflow generated from the facility is primarily industrial waste
with some domestic wastewater. Currently, the facility is aver-
aging approximately 0.38 MGD.
The Company, requests that the subject permit be modified to
include the discharge of 30,000 GPD of groundwater contaminated
with organics from extraction wells. The contaminants found in the
groundwater are Acetone (62 - 128 ug/1), Benzene (28 ug/1), 1,1
Biphenyl (2,100 - 17,040 ug/1), Phenyl Ether (7,220 ug/1) and
Trichloroethane (6 ug/1). With the exception of Benzene, there are
no water quality standards set forth for these compounds. The
water quality standard for Benzene is 71.4 ug/1 (human health).
Since the contaminated groundwater will be treated at the existing
facility prior to discharging, this Office recommends that the
subject request for permit modification be approved as long as
there would be no impact on the wastewater treatment plant that
might effect compliance with the facility's NPDES Permit.
Should you have any questions regarding this matter, please
advise.

Dear Mr. Atkins:
February 19, 1993
Subject: Draft NPDES Comments/Shelby Plant
NPDES Permit No. NC0004952
Cleveland County
This office is in receipt of your letter dated November 23, 1992 regarding comments on the
NPDES draft permit. The Division of Environmental Management (DEM) appreciates your review
and comments and offers the following responses to your requests. The responses will be in the
same order as in the November 3 letter.
1. As you stated, the headers for "Daily max." and "Monthly Avg." were reversed and have
been changed.
2. Due to the timing of the permit, the request for the effective date after January 1, 1993 is
no longer valid.
3. As stated on the Effluent Limitations page for outfall 002 under the triple asterisks
monitoring requirements only apply if chlorine is added to the cooling water. If no chlorine is
added then no monitoring is required.
4. As was discussed during the phone conversation between Randy Kepler from DEM and Terry
Atkins from Hoechst Celanese, the request for pH samples by continuous recorder was withdrawn
by Mr. Atkins due to the need for grab samples by Hoechst Celanese. However, in the future if
Hoechst Celanese decides to continuously monitor pH, the Division is amenable to modifying the
permit to reflect continuous recording.
5. The statement has been changed to the requested format reading "If the pH of the effluents
from the polishing ponds exceed 9.0, there will be no effluent violation if the wastewater from the
final clarifier has not exceeded 9.0 SU during the thirty (30) days preceding the measurements
of the pH above 9.0 of the effluent from the polishing ponds"

Mr. Atkins
6. The request for weekly monitoring of pH on the Effluent Limitations -Page 2 has been
agreed upon and changed accordingly.
7. Per a phone conversation between Randy Kepler of DEM and Terry Atkins of Hoechst
Celanese the compliance schedule will read as follows:
- Begin Construction (Contractor on site and authorization to proceed executed)
September 1. 1993
- Complete construction ( all treatment units in place and in operation) on or before
October 1, 1994
- Achieve compliance with final limitations on or before
October 1, 1994
S. On the pages of Effluent Limitations and Monitoring requests lists of OCPSF parameters,
the request for composite samples has been partially accepted: All the parameters have been
changed to composite samples except the volatile organic compounds which need to be collected as
grab samples. In accordance with approved DEM and EPA procedures, grab samples are required
to ensure accurate measurement of these compounds. These compounds can be easily volitalized
during sample collection and compositing therefore, not providing an accurate assessment of the
concentration In the effluent. Also requested is a definition of total phenolic compounds as it
pertains to this permit. The total phenolic compound list Is 2-Chlorophenol, 2,4-
Dichlorophenol, 2,4-Dimethylphenol, 2-Nitrophenol, 4-Nitrophenol, 2,4-Dinitrophenol,
Phenol. The concerns with these parameters are the toxicity, odor and taste problems that occur
with there presence. Either EPA Test Method 604 or EPA Test Method 625 will be acceptable in
testing of these parameters.
9. Part II of the Draft NPDES permit section regarding Test Procedures references the
necessary regulations to provide approval to the requested specific EPA Methods. This section
references 40 CFR 136 which defines both EPA Method 624 and 625 as appropriated analytical
procedures. The mention of these methods in Part II of the NPDES permit is not necessary. As
requested EPA Method 624 and 625 are acceptable for testing for the NPDES permit monitoring
requirements.
10. Attached are the requested forms MR 1, MR 1.1, MR 2, MR 3, AT-1 and the Annual
Pollutant Analysis Monitoring( APAM) Reporting Form A. The list requested for each analytical
fraction is included in the APAM. The acceptable EPA Methods for these parameters are stated in
40 CFR 136 and each test has different methods for testing. A discussion with a Laboratory to
determine which procedures they are certified by the state to conduct will need to be done. For
booklets of the MR forms, you may contact Tam! Andrews at 919 733-5083.
In accordance with your application for discharge permit received on September 5, 1989
we are forwarding herewith the subject state - NPDES permit. This permit is issued pursuant to
the requirements of North Carolina General Statute 143-215 .1 and the Memorandum of
Agreement between North Carolina and the US Environmental Protection agency dated December 6,
1983.

February 19, 1993
Mr. Atkins
If any parts, measurement frequencies or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request
within thirty (30) days following receipt of this letter. This request must be in the form of a
written petition, conforming to Chapter 1508 of the North Carolina General Statutes, and filed
with the Office of Administrative Hearings, Post Office Drawer 27447, Raleigh, North Carolina
27611 -7447. Unless such demand is made, this decision shall be final and binding.
Please take notice this permit is not transferable: Part 11, B.2. addresses the requirements
to be followed in case of change in ownership or control of this discharge. This permit does not
affect the legal requirements to obtain other permits which may be required by the Division of
Environmental Management or permits required by the Division of land Resources, Coastal Area
Management Act or any other Federal or Local governmental permit that may be required.
If you have any questions, please contact Mr. Randy Kepler at telephone number 919l733-

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 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 I of the permit.

Part II
Page 2 of 14
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 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.
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
WW6;iTa_,3 ...i �.
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.
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
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 are 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 of time not
exceeding 15 minutes; the grab sample can.be taken manually. Grab samples must be
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 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).'

Part II
Page.4 of 14
c. 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.
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.
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to
Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
The permittee must comply with all conditions of this permit. Any permit noncompliance
constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit
termination, revocation and reissuance, or modification; or denial of a permit renewal
application.
a. The permittee shall comply with effluent standards or prohibitions established under
section 307(a) of the Clean Water Act for toxic pollutants and with standards for sewage
sludge use or disposal established under section 405(d) of the Clean Water Act within the
time provided in the regulations that establish these standards or prohibitions or standards
for sewage sludge use or disposal, even if the permit has not yet been modified to,
incorporate the requirement.
b. The Clean Water Act provides that any person who violates a permit condition is subject to
a civil penalty not to exceed $25,000 per day for each violation. Any person who
negligently violates any permit condition is subject to criminal penalties of $2,500 to
$25,000 per day of violation, or imprisonment for not more than 1 year, or both. Any
person who knowingly violates permit conditions is subject to criminal penalties of $5,000
to $50,000 per day of violation, or imprisonment for not more than 3 years, or both. Also,
any person who violates a permit condition may be assessed an administrative penalty not
to exceed $10,000 per violation with the maximum amount not to exceed $125,000. [Ref. -
Section 309 of the Federal Act 33 U.S.C. 1319 and 40 CFR 122.41 (a)]
c. Under state law, a civil penalty of not more than ten thousand dollars ($10,000) per
violation may be assessed against any person who violates or fails to act in accordance with
the terms, conditions, or requirements of a permit. [Ref: North Carolina General Statutes
§ 143-215.6A]
d. Any person may be assessed an administrative penalty by the Administrator for violating
section 301,_ 302, 306, 307, 308, 318, or 405 of the Act, or any permit condition or
limitation implementing any of such sections in a permit issued, under section 402 of the
Act. Administrative penalties for Class I violations are not to exceed $10,000 per violation,
with the maximum amount of any Class I penalty assessed not to exceed $25,000.

Part 11
Page 5 of 14
Penalties for Class II violations are not to exceed $10,000 per day for each day during
which the violation continues-, with the maximum amount of any Class II penalty not to

.Part 11
Page 8 of 14
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control (and related appurtenances) which are installed or used by the permittee to
achieve compliance with the conditions of this permit. Proper operation and maintenance also
includes adequate laboratory controls and appropriate quality assurance procedures. This
provision requires the operation of back-up or auxiliary facilities or similar systems which are
installed by a permittee only when the operation is necessary to achieve compliance with the
conditions of the permit.
It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this pemut.
a. Definitions
(1) 'Bypass" means the known diversion of waste streams from any portion of a treatment
facility including the collection system, which is not a designed or established or
operating mode for the facility.
(2) "Severe property damage" means substantial physical. damage to property, damage to
the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to
be exceeded, but only if it also is for essential maintenance to assure efficient operation.
These bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part H, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal

Part II
Page 9 of 14
periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.
5. Upsets
. a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment 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.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence that:
(1) An upset occurred and that the permittee can identify the cause(s) of the upset;
(2) The permittee facility was at the time being properly operated; and
(3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this
permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset
has the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in
a manner such as to prevent any pollutant from such materials from entering waters of the State
or navigable waters of the United States. The permittee shall comply with all existing federal

Dear Mr. Mayrose: Cleveland County
The Division of Environmental Management (DEM) has reviewed the application and
supporting comments and information received concerning the discharge from Hoechst Celanese
Corporation Shelby Plant. DEM would like to apologize for the delay of the draft permit.
Circumstances had suspended the files while the review was pending and have now been completed.
In the permit _there exists a compliance schedule which lists dates for completion of
construction, operation and compliance with the limitations. These dates were prepared in
November 1990 and may no longer be correct. If these dates are incorrect then Hoechst Celanese
should submit the corrected dates so they may be reviewed for insertion in the permit.
Attached is a copy of the draft permit for your review. This permit draft has been approved
by the Raleigh office and the Regional Offices. DEM plans to send this draft permit to notice in
thirty (30) days to be published in the paper on October 30, 1992. After that date there will be
a thirty day -comment period .for the public in which Hoechst Celanese may also comment. If we
receive no comment then DEM will assume the draft is correct. If you have any questions feel. free
to call Randy Kepler at 919 733-5083.
incerely.

The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined. in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 6.5% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from issuance of this
permit during the months of March, June, September and December. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be reopened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting (within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
E. The permittee shall conduct a test for pollutants annually at the effluent from the treatment
plant. The discharge shall be evaluated as follows: 1) A pollutant analysis of the effluent must be
completed annually using EPA approved methods for the following analytic fractions: (a)
purgeables (i.e., volatile organic compounds); (b) acid extractables; (c) base/neutral extractables;
(d) organochlorine pesticides and PCB's (e) herbicides; and (f) metals and other inorganics. The
Form A and
Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting
accompanying memo, to be provided to all discharges affected by this monitoring requirement,
describes the sampling and analysis requirements and lists chemicals to be included in the
pollutant analysis. This monitoring requirement is to be referred to as the "Annual Pollutant
Analysis Monitoring Requirement" (APAM).

2) Other significant levels of synthetic organic chemicals must be identified and approximately
quantified. For the purpose of implementing this requirement, the largest 10 GC/MS peaks in the
purgeable, base/neutral extractable, and acid extractable fractions (or fewer.than 10, if less than 10
unidentified peaks occur) for chemicals other than those specified on the APA Requirement
Reporting Form A should be identified and .approximately quantified as stated in the APAM
Reporting Form A instructions. This part (item 2) of the APAM requirement is to be referred to as
the "10 significant peaks rule".
F. Biocide Condition
The permittee shall obtain authorization from the Division of Environmental Management prior to
utilizing any biocide in the cooling water. The permittee shall notify the Director in writing not
later than ninety (90) days prior to instituting use of any additional biocide used in cooling systems

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 measuredduring 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.

a. The it 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 Units" 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 Units" 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 Units" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, it 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.
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.
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.
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 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 are equal in
number of hours to the detention time of the system in nuber of days. However, in
m
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 of time not
exceeding 15 minutes; the grab sample can be taken manually.
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.

Part U
Page 4 of 14
b. 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 0).
c. 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.
10. Calendar DU
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

Property damage;

Part II
Page 9 of 14
(b) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate
backup equipment should have been installed in the exercise of reasonable
engineering judgment to prevent a bypass which occurred during normal
periods of equipment downtime or preventive maintenance; and
(c) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering
its adverse affects, if the Permit Issuing Authority determines that it will meet the
three conditions listed above in Paragraph d. 0) of this section.
Mid
a. 'Definition.
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations because of
factors beyond the reasonable control of the permittee. An upset does not include
noncompliance to the extent caused by operational error, improperly designed.treatment
facilities, inadequate treatment 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.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence
that:
(a) An upset occurred and that the permittee can identify the cause(s) of the upset;
(b) The permittee facility was at the time being properly operated; and
(c) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of
this permit.
(d) The permittee complied with any remedial measures required under Part II, B. 2. of
this permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.

Subject: Draft NPDES permit
NPDES Permit No. NC0004952
Shelby Plant
Cleveland County
The Division of Environmental Management (DEM) has reviewed the application and
supporting comments and information received' concerning the discharge from Hoechst Celanese
Corporation Shelby Plant. DEM would like to apologize for the delay of the draft permit.
Circumstances had suspended the files while the review was pending and have now been completed.
In the permit there exists a compliance schedule which lists dates for completion of
construction, operation and compliance with the limitations. These dates were prepared in
November 1990 and may no longer be correct. If these dates are incorrect then Hoechst Celanese
should submit the corrected dates so they may be reviewed for insertion in the permit.
Attached is a copy of the draft permit for your review. This permit draft has been approved
by the Raleigh office and the Regional Offices. DEM plans to send this draft permit to notice in
thirty (30) days to be published in the paper on October.30, 1992. After that date there will be
a thirty day comment period for the public in which Hoechst Celanese may also comment. If we
receive no comment then DEM will assume the draft is correct. If you have any questions feel free
to call Randy Kepler at 919 733-5083.

Part III Permit No. NC0004952
D.
The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in: ,
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 6.5% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from issuance of this
permit during the months of March, June, September and December. Effluent sampling for this
.testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream., this
permit may be reopened and modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting (within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
E. The permittee shall conduct a test for pollutants annually at the effluent from the treatment
plant. The discharge shall be evaluated as follows: 1) A pollutant analysis of the effluent must be
completed annually using EPA approved methods for the following analytic fractions: (a)
purgeables (i.e., volatile organic compounds); (b) acid extractables; (c) base/neutral extractables•
(d) organochlorine pesticides and PCB's (e) herbicides; and (f) metals and other inorganics. The
Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting Form A and
accompanying memo, to be provided to all discharges affected by this monitoring requirement,
describes the sampling and analysis requirements and lists chemicals to be included in the
pollutant analysis. This monitoring requirement is to be referred to as the "Annual Pollutant
Analysis Monitoring Requirement" (APAM).

2) Other significant levels of synthetic organic chemicals must be identified and approximately
quantified. For the purpose of implementing this requirement, the largest 10 GC/MS peaks in the
purgeable, base/neutral extractable, and acid extractable fractions (or fewer than 10, if less than 10
unidentified peaks occur) for chemicals other than those specified on the APA Requirement
Reporting Form A should be identified and approximately quantified as stated in the APAM
Reporting Form A instructions. This part (item 2) of the APAM requirement is to be referred to as
the "10 significant peaks rule".
F. Biocide Condition
The permittee shall obtain authorization from the Division of Environmental Management prior to
utilizing any biocide in the cooling water. The permittee shall notify the Director in writing not
later than ninety (90) days prior to instituting use of any additional biocide used in cooling systems

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 I of the permit.

Part H
Page 2 of 14
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.
•r-r�r:••r U�. n n r
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 Units" 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 Units" 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 Units" 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.
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.

Part H
Page 3 of 14
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.
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.
F•' • ON.�I •
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 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 are 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 of time not
exceeding 15 minutes; the grab sample can be taken manually.
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.

Part II
Page 4 of. 14.
b. 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).
c. 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.
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.
A hazardous substance means any substance designated under 40 CFR Part 116 pursuant
to Section 311 of the Clean Water Act.
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water

2. Proper Qperation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control. (and related appurtenances) which are installed or used by the
permittee to achieve compliance with the conditions of this permit. Proper operation and
maintenance also includes adequate laboratory controls and appropriate quality assurance
procedures. This provision requires the operation of back-up or auxiliary facilities or
similar systems which are installed by a permittee only when the operation is necessary to
achieve compliance with the conditions of the permit.
It shall not be a defense for a permittee in an enforcement action that it would have been
necessary to halt or reduce the permitted activity in order to maintain compliance with the
condition of this permit.
a. Definitions
(1) 'Bypass" means the known diversion of waste streams from any portion of a
treatment facility including the collection system, which is not a designed or
established.or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage
to the treatment facilities which causes them to become inoperable, or substantial
and,permanent loss of natural resources which can reasonably be expected to occur
in the absence of a bypass. Severe property damage does not mean economic loss
caused by delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations
to be exceeded, but only if it also is for essential maintenance to assure efficient
operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of
this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need fora bypass, it.
shall submit prior notice, if possible at least ten days before the date of the bypass;
including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass
as required in Part II, E. 6.'of this permit. (24-hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(a) Bypass was unavoidable to prevent loss of life, personal injury or severe
property damage;

Part II
Page 9 of 14
(b) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate
backup equipment should have been installed in the exercise of reasonable
.engineering judgment to prevent a bypass which occurred during normal
periods of equipment downtime or preventive maintenance; and
(c) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering
its adverse affects, if the Permit Issuing Authority determines that it will meet the
three conditions listed above in Paragraph d. (1) of this section.
5. Upsets
a. 'Definition.
"Upset " means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations because of
factors beyond the reasonable control of the permittee. An upset does not include
noncompliance to the extent caused by operational error, improperly designed treatment
facilities, inadequate treatment facilities, lack of preventivemaintenance, 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.
c. Conditions necessary for a demonstration of upset.
1
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs, or other relevant evidence
that:
(a) An upset occurred and that the permittee can identify the cause(s) of the upset;
(b) The permittee facility was at the time being properly operated; and
(c) The permittee submitted notice of the upset as required in Part H, E. 6. (b) (B) of
this permit.
(d) The permince complied with any remedial measures required under Part H, B. 2. of
this 'permit.
d.. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.

Part II

Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be disposed of in accordance with NCGS 143-215.1 and in a
manner such as to prevent any pollutant .from such materials from entering waters of the
State or navigable waters of the United States. The permittee. shall comply with all existing
federal regulations governing the disposal of sewage sludge. Upon promulgation of 40
CFR Part 503, any permit issued by the Permit Issuing Authority for the disposal of sludge
may be reopened and modified, or revoked and reissued, to incorporate applicable
requirements at 40 CFR Part 503. The permittee shall comply with applicable 40 CFR Part
503 Standards for the Use and Disposal of Sewage Sludge (when promulgated) within the
time provided in the regulation, even if the permit is not modified to incorporate the

Division and final plans and specifications for the subject project have been reviewed and found to
be satisfactory. Authorization is hereby granted for the construction of a 21,600 gpd wastewater
treatment system to treat the centrifuge water and stormwater from the CERCLA project which
consists of a 21,000 gallon storage tank, a 50 gpm transfer tank, a cartridge filter with
approximately 160 sf of filter area, a 100,000 gpd carbon adsorption unit and a 75,000 gallon
carbon adsorption unit with discharge of treated wastewater into Polishing Pond B which
discharges to outfall 001 with ultimate discharge into Buffaloe Creek classified as C waters.
This Authorization to. Construct is issued in accordance with Part III paragraph A of
NPDES Permit No. NC0004952 issued August 18, 1988, and shall be subject to revocation unless
the wastewater treatment facilities are constructed in accordance with the conditions and limitations
specified in Permit No. NC0004952.
The sludge generated from these treatment facilities must be disposed of in accordance with
G.S. 143-215.1 and in a manner approved by the North Carolina Division of Environmental
Management.
In the event that the facilities fail to perform satisfactorily, including the creation of
nuisance conditions, the Permittee shall take immediate corrective action, including those as may be
required by this Division, such as the construction of additional or replacement wastewater
treatment or disposal facilities.
The Mooresville Regional Office, phone no. [phone], shall be notified at least
forty-eight (48) hours in advance of operation of the installed facilities so that an in -place
inspection can be made. Such notification to the regional supervisor shall be made during the
normal office hours from 8:00 a.m. until 5:00 p.m. on Monday through Friday, excluding State
Holidays.

The Permittee shall employ a certified wastewater treatment plant operator to be in
responsible charge of the wastewater treatment facilities. The operator must hold a certificate of the
grade at least equivalent to the classification assigned to the wastewater treatment facilities by the
Certification Commission. Within thirty days after the wastewater treatment facilities are 50%
complete, the Permittee must submit a letter to the Certification Commission which designates the
operator in responsible charge.
A copy of the approved plans and specifications shall be maintained on file by the Permittee
for the life of the facility.
Failure to abide by the requirements contained in this Authorization to Construct may
subject the Permittee to an enforcement action by the Division of Environmental Management in
accordance with North Carolina General Statute 143-215.6.
The issuance of this Authorization to Construct does not preclude the Permittee from
complying with any and all statutes, rules, regulations, or ordinances which may be imposed by
other government agencies (local, state, and federal) which have jurisdiction.

The effluent discharge shall at no time exhibit chronic toxicity in any two consecutive toxicity tests,
using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic
Bioassay Procedure - Revised *September 1989) or subsequent versions.
The effluent concentration at which there may be no observable inhibition of reproduction or
significant mortality is 4.5% (defined as treatment two in the North Carolina procedure document).
The permit holder shall perform quarterly monitoring using this procedure to establish compliance
with the permit condition. The first test will be performed after thirty days from issuance of this -
permit during the months of March, June, September and December. Effluent sampling for this
testing shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter
code TGP3B. Additionally, DEM Form AT-1(original) is to be sent to the following address:
Attention:
Environmental Sciences Branch
North Carolina Division of
Environmental Management
P.O. Box 27687
Raleigh, N.C. 27611
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual
chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring will begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Environmental Management indicate potential impacts to the receiving stream, this
permit may be reopened and modified to. include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum
control organism survival and appropriate environmental controls, shall constitute an invalid test
and will require immediate retesting (within 30 days of initial monitoring event). Failure to submit
suitable test results will constitute noncompliance with monitoring requirements.
E. The permittee shall conduct a test for pollutants annually at the effluent from the treatment
plant. The discharge shall be evaluated as follows: 1) A pollutant analysis of the effluent must be
completed annually using EPA approved methods .for the following analytic fractions: (a)
purgeables (i.e., volatile organic compounds); (b) acid extractables; (c) base/neutral extractables;
(d) organochlorine pesticides and PCB's (e) herbicides; and (f) metals and other inorganics. The
Annual Pollutant Analysis Monitoring (APAM) Requirement Reporting Form A and
accompanying memo, to be provided to all discharges affected by this monitoring requirement,
describes the sampling and analysis requirements and lists chemicals to be included in the
pollutant analysis. This monitoring requirement is to be referred to as the "Annual Pollutant
Analysis Monitoring Requirement" (APAM).

2) Other significant levels of synthetic organic chemicals must be identified and approximately
quantified. For the purpose of implementing this requirement, the largest 10 GC/MS peaks in the
purgeable, base/neutral extractable, and acid extractable fractions (or fewer than 10, if less than 10
unidentified peaks occur) for chemicals other than those specified on the APA Requirement
Reporting Form A should be identified and approximately quantified as stated in the APAM
Reporting Form A instructions. This part (item 2) of the APAM requirement is to be referred to as_ _
the "10 significant peaks rule".
F. The permittee shall not use any biocides except those approved in conjunction with the permit
application. The permittee shall notify the Director in writing not later than ninety (90) days prior
to instituting use of any additional biocide used in cooling systems which may be toxic to aquatic
life other than those previously reported to the Division of Environmental Management. Such
notification shall include completion of Biocide Worksheet Form 101 and a map locating the "
discharge point and receiving stream.

and shall be monitored as specified above.

A. (1) (a). EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS
Note: #1. Higher flows along with proportional increases in pollutants discharged caused by rainfall will not
constitute a violation of the permit if the hydrological event can be documented by permittee through
rain gauge records.
*The pH of the wastewater at a point between the final clarifiers and final polishing pond, such a point
being after the combination of all potential influents to polishing pond, shall not be less than 6.0 Standard
Units nor greater than 9.0 Standard Units. If the pH of the effluent from the polishing ponds exceeds 9.0,
there will be no violation if the wastewater from the final clarifier has met the required pH limits during
the thirty (30). days preceeding the measurement of the pH above 9.0 of the effluent from the polishing ponds.
The pH of the wastewater from the clarifiers and the pH of the effluent from the polishing ponds (final
discharge) will be monitored by continuous recorder.

Upsets
"Upset" means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the permittee. An upset
does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities,
lack of preventive maintenance, or careless or improper operation. An upset
constitutes an affirmative defense to an action brought for noncompliance
with such technology based permit limitation if the requirements of 40 CFR S
122.41(n)(3) are met.
Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of
treatment `or control of wastewaters shall be disposed of in accordance with.
NCGS 143-215.1 and in a manner such as to prevent any pollutant from such
materials from entering waters of the State or navigable waters of the United
States.
Power Failures
The permittee is responsible for maintaining adequate safeguards as requi.r.nd
by DEM Regulation, Title 15, North Carolina Administrative Code, Subchapter. 21i,
.01.24 Reliability, to prevent the discharge of untreated or inadequately treated.
wastes during electrical power failures either by means of alternate power
sources, standby generators or retention of inadequately treated effluent.
SECTION C. MONITORING AND RECORDS
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be '
characteristic of the volume and nature of the permitted discharge. Samples
collected at a frequency less than daily shall be taken ona day and .time that
is characteristic of the discharge over the entire period which the sample
represents. All samples shall be taken at the monitoring points specified in
this permit and, unless otherwise specified , before the effluent joins or is

The Federal Water Pollution Control Act, also known as the. Clean Water Act, as
amended, 33 USC 1251, et. seq.
5. Mass/Da7Measurements
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 sample and measured, divided by the number
of daily discharges samples and/or measured during siicli 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 "Daily Average" or "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 samples 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 Averags" in P,,jrt: ] of the permit.
C. The "maximum daily discharge" is tha total mass (w(aight:) of a
pollutant discharged during a calendar clay. If only cl.e sample is
taken during any calendar day the weight of pol.l.ut:a?lt 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 sample 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 thei) dividing this sum by the
number of days the tests were reported. This li.mit.ati.on is defined as
"Annual Average" in. Part I of the permit.

Part II
Page 12 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
samples 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 a.11 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" or
"Daily 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 da-1.1.y discharges sampled
and/or measu..red 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. It is identified as "Daily Maximum"
under "Ot.ber_ Limits" .rt '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. Limit.,;' in Part I of the
permit.

Other 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.
Types of Samples
a. Composite Sample: These samples consist of grab samples collected at
equal intervals and combined proportional to flow, a sample continuously
collected proportionally to flow, or equal volumes taken at varying time
intervals. If a composite sample is obtained from grab samples, the
following requirements apply. The intervals between influent grab
samples shall be no greater than hourly. Intervals between effluent grab
samples shall be no greater than hourly except where the detention time
of the wastewater in the facility is greater than 24 hours, in which
case, the interval between grab samples shall be no greater in number of
hours than the detention time in number of days; provided, however, in
no case may the time between effluent grab samples be greater than six
hours nor the number of grab samples less than four during any discharge
period of 24 hours or less.
b. Grab Sample: Grab samples are individual samples collected over a
period of time not exceeding 15 minutes; the grab sample can be taken
manually.
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 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).
C. 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.

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.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of

IV - RECOMMENDATIONS
Zinc will be the limiting metal in Fiber Industries' land application
system. At an annual sludge application rate of 1.6 million gallons per
year, the designated disposal site can be used for the year 1983 plus 3.5
additional years. At the projected application rate, ava.ilable nitrogen
loadings will be less than 300 lbs/acre and the cadmium loading will be
held to less than the recommended 0.5 lbs/acre/year.
The Regional Office recommendation is that Non Discharge Permit #72.41
be renewed and that the allowed application rate be increased to 1.6 mg/yr;
the expiration date of the reissued permit should be December 31, 1986.

INTRODUCTION
The Hoechst Celanese Corporation's fiber production facility is located at Shelby in Cleveland county,
North Carolina. In June 1986, the Shelby facility was added to the National Priority List (NPL) by the
Environmental Protection Agency (EPA). The remedial investigation and feasibility studies (RI/FS) were
completed in April, 1989. The recommended remedial action for the management of the contaminant
sources consists of:
o excavation of glycol recovery unit (GRUB sludges, plastic chip, burn pit residuals, and
selected stream sediments
0 on -site incineration of GRU sludges and associated contaminated soils
o solidification of incineration ash, burn pit residuals, and stream sediments
0 on -site disposal of inert, solidified material
o regrading and revegetation
o monitoring
A 100% remedial design report was prepared to achieve the above mentioned remediation work, and the
report was approved by the EPA in September, 1990.
Westinghouse Environmental and Geotechnical Services, Inc. of Atlanta has prepared the remedial design
report. GDC Engineering, Inc. of Baton Rouge has been contracted by Hoechst Celanese to perform the
on -site incineration and solidification.
Wastewater will be generated during the on -site remediation work and will be treated by a portable
wastewater treatment system to meet the Hoechst Celanese's NPDES discharge requirements. Once
these discharge criteria are met, the treated wastewater may be discharged into the polishing ponds prior
to the plant's NPDES outfall. This report is submitted to the North Carolina Department of Health,
Environment and Natural Resources (NCDHENR) to receive an authorization to install the wastewater
treatment system.
Wastewater Characteristics:
Wastewater that may require treatment will be generated from the following three sources:
o stormwater or water collected in the excavated areas
5050 N006. W PS

o centrate water from the centrifugation of slurried stream sediments (20,000 gallons)
o decontamination water (20,000 gallons)
The quantity of stormwater cannot be estimated. However, appropriate steps will be taken to minimize the
amount of stormwater. In order to select wastewater treatment units, an estimate of wastewater quality is
needed. Since the data on the contaminated groundwater are available from the RI/FS studies, these data
are used to estimate the quality of wastewater that would be generated during the remedial work. Based
on RI/FS studies the probable contaminants in the wastewater may be classified as follows:
o chlorinated hydrocarbons
o polynuclear hydrocarbons
o metals
Due to low levels of organic loadings, carbon adsorption is the anticipated method for organic removal.
Since the pH of the wastewater will be near neutral the metal contaminants are expected to be adsorbed in
the suspended solids rather than in solution. Therefore it is expected that the metal contaminants will be
removed by the sedimentation and filtration followed by carbon adsorption. The schematic of the
wastewater treatment system is provided in the attached figure.
Treatment Process
The wastewater treatment system will be a batch process. Wastewater will be collected in a storage tank
which will also allow some of the suspended solids to settle. These settled solids will be removed and
solidified. Water from the storage tank will be pumped through a 15-micron 160-square foot cartridge filter.
That will remove most of the suspended solids and the metal contaminants that are adsorbed in the
suspended solids. The effluent from the cartridge filter will then flow through two carbon adsorption units.
One of the carbon units will have a capacity of 100 gallons per minute (gpm) and the other 75 gpm. The
maximum and average wastewater flow through the treatment units will be 50 gpm and 15 gpm,
respectively. The model numbers are Cansorb C-100 and Cansorb C-75, and the units will have 3000
pounds and 1500 pounds of activated carbon, respectively. The specifications for the carbon units are
obtained from the manufacturer, TIGG Corporation of Pittsburgh, Pennsylvania and are attached. The
backwash water will return to solidification. The spent carbon from the carbon adsorption units will be
incinerated on -site, or shipped off -site for regeneration or disposal as a hazardous waste. The treated
water may be discharged to the polishing pond B or it may be recycled. A 2 inch -diameter flexible hose will
be used as a discharge line from the treatment unit.
The incinerator pad showing the wastewater treatment area and the locations of the wastewater treatment
units are presented in Drawings 1 and 2, respectively. These drawings were taken from the Appendix 1 of
the 100% Remedial Design Report and modified to show the wastewater treatment area and the units.

INTRODUCTION
The Hoechst Celanese Corporation's fiber production facility is located at Shelby in Cleveland county,
North Carolina. In June 1986, the Shelby facility was added to the National Priority List (NPL) by the
Environmental Protection Agency (EPA). The remedial investigation and feasibility studies (RI/FS) were
completed in April, 1989. The recommended remedial action for the management of the contaminant
sources consists of:
o excavation of glycol recovery unit (GRU) sludges, plastic chip, burn pit residuals, and
selected stream sediments
0 on -site incineration of GRU sludges and associated contaminated soils
o solidification of incineration ash, burn pit residuals, and stream sediments
0 on -site disposal of inert, solidified material
o regrading and revegetation
o monitoring
A 100% remedial design report was prepared to achieve the above mentioned remediation work, and the
report was approved by the EPA in September, 1990.
Westinghouse Environmental and Geotechnical Services, Inc. of Atlanta has prepared the remedial design
report. GDC Engineering, Inc. of Baton Rouge has been contracted by Hoechst Celanese to perform the
on -site incineration and solidification.
Wastewater will be generated during the on -site remediation work and will be treated by a portable
wastewater treatment system to meet the Hoechst Celanese's NPDES discharge requirements. Once
these discharge criteria are met, the treated wastewater may be discharged into the polishing ponds prior
to the plant's NPDES outfall. This report is submitted to the North Carolina Department of Health,
Environment and Natural Resources (NCDHENR) to receive an authorization to install the wastewater
treatment system.
Wastewater Characteristics:
Wastewater that may require treatment will be generated from the following three sources:
o stormwater or water collected in the excavated areas

o centrate water from the centrifugation of slurried stream sediments (20,000 gallons)
o decontamination water (20,000 gallons)
The quantity of stormwater cannot be estimated. However, appropriate steps will be taken to minimize the
amount of stormwater. In order to select wastewater treatment units, an estimate of wastewater quality is
needed. Since the data on the contaminated groundwater are available from the RI/FS studies, these data
are used to estimate the quality of wastewater that would be generated during the remedial work. Based
on RI/FS studies the probable contaminants in the wastewater may be classified as follows:
o chlorinated hydrocarbons
o polynuclear hydrocarbons
o metals
Due to low levels of organic loadings, carbon adsorption is the anticipated method for organic removal.
Since the pH of the wastewater will be near neutral the metal contaminants are expected to be adsorbed in
the suspended solids rather than in solution. Therefore it is expected that the metal contaminants will be
removed by the sedimentation and filtration followed by carbon adsorption. The schematic of the
wastewater treatment system is provided in the attached figure.
Treatment Process
The wastewater treatment system will be a batch process. Wastewater will be collected in a storage tank
which will also allow some of the suspended solids to settle. These settled solids will be removed and
solidified. Water from the storage tank will be pumped through a 15-micron 160-square foot cartridge filter.
That will remove most of the suspended solids and the metal contaminants that are adsorbed in the
suspended solids. The effluent from the cartridge filter will then flow through two carbon adsorption units.
One of the carbon units will have a capacity of 100 gallons per minute (gpm) and the other 75 gpm. The
maximum and average wastewater flow through the treatment units will be 50 gpm and 15 gpm,
respectively. The model numbers are Cansorb C-100 and Cansorb C-75, and the units will have 3000
pounds and 1500 pounds of activated carbon, respectively. The specifications for the carbon units are
obtained from the, manufacturer, TIGG Corporation of Pittsburgh, Pennsylvania and are attached. The
backwash water will return to solidification. The spent carbon from the carbon adsorption units will be
incinerated on -site, or shipped off -site for regeneration or disposal as a hazardous waste. The treated
water may be discharged to the polishing pond B or it may be recycled. A 2 inch -diameter flexible hose will
be used as a discharge line from the treatment unit.
The incinerator pad showing the wastewater treatment area and the locations of the wastewater treatment
units are presented in Drawings 1 and 2, respectively. These drawings were taken from the Appendix 1 of
the 100% Remedial Design Report and modified to show the wastewater treatment area and the units.
