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 sample and measured, divided by the number
of daily discharges samples 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 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 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
if Daily Maximum," in Part I of the permit.

Part II
Page 12 of 14
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 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
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 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.

Part II
Page 13 of 14
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 minimum concentration" (for dissolved oxygen only) is the
minimum allowable amount of dissolved oxygen required to be available in
the effluent prior to discharge. It is identified as "Daily Minimum" under
"Other Limits" in Part III of the permit.
7. 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.
8. 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.

Part II
Page 14 of 14
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).
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 D
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
the Clean Water Act.

Re: American Cyanamid
NPDES Permit No. NCO040690 T
r - f: ,
Dear Mr. Gleason: <r;
Mecklenburg County Department of Environmental Protection
(MCDEP) would like to make the following comments concerning the
renewal of the above permit:
1. During the period of July 1986, to June 1987, there were only
two discharges from this facility. However, during both
discharges the BOD value was elevated above normal rainwater
runoff values.
2. The old permit only monitored flow, temperature, BOD, metals,
and pH. This was also done on a monthly frequency.
3. MCDEP recommends that a discharge limit be put on the BOD
parameter, that the discharge be measured when it occurs and
up to daily if the discharge continues over 24 hours. It is
further recommended that other parameters be considered for
monitoring spills and leaks from the storage tanks that
collect in the gravel areas and wash out during rainstorms.
We appreciate your consideration of our comments.
Sincerely,
y

year. The annual test must be performed and reported by June 30. If no discharge occurs by June
30, notification must be made to the Division by this date, and monitoring must be performed on the next
discharge event for the annual monitoring requirement.
***** These parameters shall be monitored only when there is a discharge.
The pH shall not be less than 6.0 standard units nor greater than 9.0 standard units and shall be
monitored weekly at the effluent by grab samples.
There shall be no discharge of floating solids or visible foam in other than trace amounts.

G. The Permittee shall conduct FIVE acute toxicity tests using protocols defined
in E. P. A. Document 600/4-85/013 entitled "The Acute Toxicity of Effluents to
Freshwater and Marine Organisms". The monitoring shall be performed as a
Daphnia pul.ex or Cerioda hnia 48 hour static test, using effluent
collected as a single grab sample. Effluent samples for self -monitoring
purposes must be obtained below all. waste treatment. Sampling and subsequent
test will occur during the first five discrete discharge events after the
effective date of this permit.
The parameter code for this test if using Daphnia pulex is TAA3D. The
parameter code for this test is using Ceriodaphnia is TAA3B. All toxicity
testing results required as part of this permit condition will be entered on
the Effluent Discharge Form (MR-1) for the month in which it was performed,
using the appropriate parameter code. Additionally, DEM Form AT-1 (original)
is to be sent to the following address:
Attention: Technical Services Branch
North Carolina Division of
Environmental Management
P. 0. 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 test data from either these monitoring requirements or test
performed by the North Carolina Division of Environmental Management indicate
potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document,
such as minimum control organism survival and appropriate environmental
controls, shall constitute an invalid test. Failure to submit suitable test
results will constitute a failure of permit condition.
H. In the event that violations of the fecal coliform requirements of the North
Carolina water quality standards occur as a result of this discharge,
disinfection will immediately be required and the permit amended to establish a
coliform effluent limitation.

SUBJECT:

Adjudications UMNSWnLe
Hickory -
Land Application of Slddge
Permit No.
WQ 0001669
This Office has reviewed the adjudication request from each of the two subject
facilities and offers the following comments/recommendations:
American Cyanamid
1) A review of self -monitoring data for this facility reflects effluent BOD5
levels (on occasion) above 250+ mg/l. Given the fact the discharge is
intermittent (occurring during storm events), removal of this limitation will
provide no incentive for Cyanamid to upgrade existing facilities. The
establishment of BAT limitations for BOD5 and TSS are appropriate considering
past effluent levels.
2) A memo dated November 30, 1989 from Jackie Nowell to Lula Harris documents the
need to require instream sampling for D.O. and Conductivity. This Office
concurs with her recommendation.
City of Hickory
1) Recommend a copy of the Permit be maintained in application vehicle.
2) This Office has no objection to providing an extension to AMSCO in order to
submit the required PSRP report as specified in Part I. No. 10.
3) Recommend the application rate for Phosphorous remain at 100 lbs/acre/year but
add: *or the recommended fertilizer requirement for the specific crop as
noted in the soil field analysis.
4) Hickory's original application reflected 3,000,000 gal/year of sludge.
Recommend approval of modification request pending receipt of an amended
Permit application. The additional volume should not be a problem provided
required application rates and volumes are met.
5) Recommend application rate for Cadmium be amended to EPA's required limit of
0.45 pounds/year.
6) Defer comment to Permits & Engineering.

Page Two
7) Recommend condition remain. In general these sites have limited public access
and are, for the most part, private property. The condition does not require
the posting of signs if public access is preventable. Restricting access has
not been a problem on this project.
8) An extension of the reporting requirement for all monitoring results may be
granted; however, it appears to this Office that sufficient monitoring data
can be accumulated by November of each year for which analysis, review and
reporting can be completed and submitted by the January 31st deadline.
Typically, due to wet weather, very little sludge disposal is done between
11/1 and 12/31 which should enable AMSCO to provide accurate sludge and field
data.

SUBJECT: NPDES PERMIT NO. NCO040690
AMERICAN CYANAMID COMPANY CHARLOTTE PLANT
MECKLENBURG COUNTY
Dear Ms. Harris:
This letter is in confirmation of our conference call of March 15,
1989 regarding the revised draft permit which you transmitted to
Mr. Merrell on February 13, 1989. American Cyanamid would like to
defer commenting on certain aspects of the draft permit until April
30, 1989 pending receipt of analytical data on recent samples of
the discharge. Based on our telephone conversation, I understand
that this procedure is acceptable to the Division. In the interim,
the balance of this letter will address the remaining comments we
discussed on March 15.
1. Discharge limitations -flow: A limitation on flow (either
average or maximum) seems to have no practical relevance to
the subject discharge, which consists of excess stormwater
only. Cyanamid directs all stormwater collected in the SPCC
System to its onsite effluent treatment plant and
subsequently to the Charlotte -Mecklenburg Utility Department
POTW. Only during periods of extreme rainfall (such as
occurred at the end of February, 1989) is the pumping
capacity of our effluent plant exceeded and we are compelled
to bypass the SPCC tanks and discharge excess stormwater from
the permitted outfall. Prior to 2/28/89, there had been no
discharge from this source for almost 2 years. Obviously,
stream flow in the receiving water is also at a peak during
periods when a discharge occurs. Given the infrequent nature
of the discharge and the fact that we have no practical means
of regulating flow, we request deletion of the flow
limitation from our permit.

Ms. Lula M. Harris March 21, 1989

2. Discharge limitations - BOD, TSS, phenols: As mentioned
earlier, we request an extension of time to comment on these
numerical limitations, until after we have had an opportunity
to review the analytical data from the recent sampling
event. However, consistent with our comments above on flow,
we believe that "daily average" limitations have no meaning
for an infrequent and episodic discharge. If numerical
limitations must be established for this discharge, we
request that only "daily maximum" limits be specified.
3. Monitoring Reguirements - Measurement Frequency (entire
column and footnote relative to pH monitoring): For the
reasons discussed above, any calendar -based or specific
periodic measurement frequency has no meaning for an
unpredictable, infrequent, and episodic discharge. American
Cyanamid requests deletion of the specified frequencies and
substitution of "per discharge event" for all parameters
subject to monitoring.
4. Monitoring Reguirements - Sample Type (Flow): The
requirement for continuous recording of flow seems excessive
for a highly infrequent discharge. Previously, we have
provided flow estimates, based on a series of visual
observations of weir height readings during discharge
events. We request continuation of this procedure and
substitution of "estimation" for "recording" in the sample
type column for flow monitoring.
5. Monitoring Requirements - Instream Monitoring: As currently
written, the draft permit would require periodic instream
monitoring (U,D) for temperature, dissolved oxygen, and
conductivity. Even if the measurement frequencies were
respecified as "per discharge event", we question whether
instream monitoring for these parameters will be able to
detect any significant effect of the discharge on the
stream. Stream flow during a discharge event will
necessarily be at a maximum due to areawide stormwater
runoff. Hence, we believe it will be impossible to discern
any incremental impact of the discharge of excess stormwater
by instream monitoring of the specified (or any other)
parameters. If DEM feels that some instream monitoring is
necessary, for the purpose of this permit, we suggest
continuation of the historical instream monitoring parameters
(BOD, pH,temperature), using grab samples, on a per discharge
event frequency. We would further request that the sample
locations be specified as follows: U = Upstream at Highway
74; D = Downstream at Old Dowd Road, as the closest points
which are safely accessible.

Ms. Lula M. Harris March 21, 1989

6. Monitoring Requirements - Acute Toxicity: The footnote
(****) that apparently corresponds to the measurement
frequency (***) for Acute Toxicity states that the annual
test must be performed and reported by June 30. If a
discharge were to occur close to June 30, it may be
impossible to complete the test and report the results by
this deadline. We suggest separating the testing and
reporting deadlines by a reasonable period, e.g., 1 month.
Similarly, in the next sentence, a reasonable period of time
should be allowed for notification, if no discharge occurs by
June 30. We also request that the sample type for acute
toxicity monitoring specified in the Table (A.1) (composite)
be made consistent with the sample requirements stated in the
first paragraph of condition G (grab).
American Cyanamid appreciates the opportunity to submit these
comments on the current draft permit. As indicated, we anticipate
forwarding additional comments, along with analytical data on the
recent discharge to you by the end of April. In the interim, if
you have any immediate questions on this submission, please do not
hesitate to contact me at [phone] or Heath Howie at the

Mecklenburg County, NC
Dear Mr. Carty:
Our records indicate that NPDES Permit No. NC 0040690 was
issued on January 8, 1990 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 M3.
Page M3 sets forth the effluent limitations and monitoring
requirements for your discharge(s). Your discharge(s) 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 the
reporting forms furnished to you by this Agency. If you have not
received these forms, they should be arriving shortly. If you
fail to receive the form, 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.
The remaining Parts of the Permit (Parts II and III) 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 plus 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 M-1 or I-1
of the Permit. Also note that NPDES Permits are not
transferable. If you, as the Permittee, cease to need this
Permit, then you should request that the Permit be rescinded.
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.

SUBJECT: Comments regarding American Cynamid Company Permit Objections
NPDES No. NC0040690, Mecklenburg County
I have reviewed the letter from American Cynamid requesting relief from sev-
eral proposed parameters in the permit. The comments submitted by the company
warrant consideration. However, the company's assertation that the only poten-
tial element of concern is zinc -nitrate is in conflict with the regional staff
report. I recommend changing the permit limits for C,' Cr, Cu, Ni, Pb, and Zn
to monitoring requirements and including a reopener clause to allow for
limitation if deemed appropriate. Given the rare discharge occurrence under
storm events, I also recommend changing the BOD5 requirement to the BAT limit of
61 mg/l monthly average and 163 mg/l daily maximum. Both the BAT BOD5 and TSS
requirements appear appropriate in light of the region's staff report, in ;piugQhtof the company's objections. Monitoring for TSS, BOD, pH, and the metals s
be switched to require sampling everyday of discharge per the region's request.
This sampling frequency can be re-evaluated after several events have been moni-
tored. Whole -effluent toxicity monitoring should be maintained, but the test
should be changed to an episodic monitoring requirement to correspond with its
stormwater nature (see attached).
Please let me know if further clarification is required.

Dear Mr. Overcash:
SUBJECT: American Cyanamid Company Charlotte Plant
NPDES Permit No. NCO040690
y;.
Pursuant to 40 CFR 124.11 American Cyanamid Company (Cyanamid)
is submitting the comments below on the subject proposed NPDES
permit public notice on April 20, 1988- Cyanamid believes the
proposed effluent characteristics and monitoring requirements
are inappropriate to the nature of this infrequent stormwater
bypass discharge. By way of this letter we are requesting a
meeting with your department personnel to further discuss these
written comments. It is our understanding per your conversation
with Raymond Merrell on May 16, 1988 that the permit will not be
issued until these comments are addressed and a formal extension
of the comment period beyond June 2, 1988 is not necessary to
allow time for our meeting.
• �; ti,,� Il 11
Cyanamid submitted in a time manner an application for renewal
of the Charlotte plant NPDES stormwater discharge permit No.
NCO040690 on November 24, 1987 with a minor correction to the
flow data submitted on February 2, 1988- The plant also
operates a secondary wastewater treatment system that pretreats
all routine facility effluents, including normal stormwater
runoff, prior to the permitted discharge into the
Charlotte -Mecklenburg Utility Department's (CMUD-POTW)_
The NPDES permit renewal is for the non -routine discharge of
excessive stormwater bypassing the Spill Prevention, Control and
Countermeaure (SPCC) basin during heavy rain events. A
stormwater bypass only occurs during a rainfall event that is so
intense and/or persistent as to exceed the capacity of the
plant's effluent treatment system. Such discharges have

Page 2
Mr. Dale Overcash
May 27, 1988
historically been very infrequent with the last discharge
occurring in January, 1987. Future discharges are similarly
expected to be infrequent, particulary since the 1987
installation of new flow meters, without flow restrictions,
allowing for improved control of water levels in the effluent
treatment system. The maximum daily flow of this non -routine
discharge during major storm events is estimated at 100,000
gpd. The existin S permit issued to Cyanamid on June 15,
1983 specifies 'monthly monitoring" for temperature, pH and BODS
o In y_ The proposed NPDES permit renewal specifies more extensive
monitoring of this stormwater bypass discharge based on North
Carolina Water Quality Standards (WQS - NCAC Title 15, Chapter 2
Subpart B et. seq.) and EPA's categorical effluent guidelines
for the Organic Chemicals, Plastics and Synthetic Fibers
Industries (OCPSF - 40 CFR 414 et. seq.) both having taken
effect since our last permit renewal in 1983. Our comments on
the draft NPDES permit focus primarily on the application of the
WQS and OCPSF effluent limitations on the discharge in addition
to the monitoring frequency requirements for this infrequent
storm event discharge.
A_ OCPSF EFFLUENT GUIDELINES
Cyanamid believes the application of the OCPSF effluent
guideline is inappropriate to the nature of this discharge.
The Charlotte plant manufactures specialty organic chemicals
and resins (SIC Codes 2869 and 2821) subjecting the plant's
process discharges to 40 CFR 414 et. seq. As previously
described, all routine process discharges are pretreated
prior to discharging into CMUD-POTW_ Although OCPSF applies
by virtue of SIC Codes, the plant does not handle as a raw
material or manufacture any of the regulated priority
pollutants in OCPSF processes. The only priority pollutant
recognized in use at the site is zinc from a non-OCPSF
inorganic zinc nitrate manufacturing process.
We believe this excess stormwater bypass is unique and was
not intended by EPA to be regulated under the OCPSF
guidelines. Since the first flush of any stormwater
potentially containing pollutant is always directed to our
pretreatment system, by the time stormwater bypass is
necessary to prevent flooding of the pretreatment system,
there would be no correlation between the discharge and
OCPSF production activities. The inappropriateness of
r
r

Page 3
Mr. Dale Overc:ash
May 27, 1988
applying OCPSF limitations to this stormwater bypass is further
evidenced by the fact that the only production activity
involving a listed priority pollutant is the non-OCPSF
manufacturing of inorganic zinc nitrate! Therefore we believe
the proposed permit parameters are inappropriate and not
expected to be in our discharge as indicated on our permit
application.
Specific comments on the proposed effluent limitations based on
applying OCPSF categorical guidelines are provided below:
1. Phenols total copper and total zinc
Limitations for these parameters are based on Best Available
Technology (BAT) as defined in 40 CFR 414.100 Subpart J -
Direct Discharge Point Sources That Do Not Use End -of -Pipe
Biological Treatment. We believe application of these OCPSF
limitations are inappropriate to the excess stormwater
bypass discharge for reasons previously described_
2. Total Suspended Solids (TSS)
TSS limitations were based on Best Practicable Control
Technology Currently Available (BPT) as defined in 40 CFR et
seq. We believe this is an inappropriate application of
OCPSF limitations for reasons previously described.
Applying TSS OCPSF limitations to this excess stormwater
bypass is particulary inappropriate since the major source
of TSS would be from natural surface erosion totally
unrelated to OCPSF production operations.
B. NORTH CAROLINA WATER QUALITY STANDARDS
Most of the proposed NPDES permit limitations were based on
WQS as the discharge impacts the unnamed tributary to Paw
Creek, a class C stream in Catawba River Basin. As we
understand, the WQS limitations were derived from modeling
the unnamed tributary with a 7Q10 flow of 0 CFS. This
approach results in the application of the WQS directly to
our end -of -pipe stormwater discharge representing 100% of
the stream flow. We believe this standard modeling is not
applicable to our discharge since it does not take into
account the nature of the discharge being excessive
stormwater resulting only during times when there would be
significant flow in the receiving unnamed tributtry.
In accordance with NCAC Title 15, Chapter 2 Subpart B
Section 0.0206(a)(3}, Cyanamid requests a re-evaluation of
the WQS applied to this stormwater event discharge utilizing
"...other established modeling techniquesrand corresponding
flow criteria for the determination of waste load
allocations for toxic substances...".
•

Page 4
Mr. Dale Overcash
May 27, 1988
This re-evaluation would affect the proposed permit limitations
for BOD, chrome, lead, cyanide and nickel. In addition, other
WQS parameters listed for monitoring but without limitations
include dissolved oxygen, temperature, conductivity, total
nitrogen, total phosphorous and chronic toxicity.
CONCLUSION
These comments to the proposed NPDES permit summarized the
misapplication of OCPSF categorical effluent guidelines to our
intermittent discharge of excess stormwaters. We request a
re-evaluation of the WQS which were incorrectly applied to our
infrequent stormwater discharge based on the assumption of zero
flow in the receiving tributary to Paw Creek during heavy storm
events. Finally, we request reconsideration of monitoring
frequencies and parameters to more properly reflect the
intermittent and infrequent nature of the storm event discharge.
Feel free to contact either Heath Howie, our Charlotte plant
chemist, (704-394-4361) or Raymond Merrell of our N.J. corporate
staff (201-831-2873) with any questions regarding these
comments. Please also contact us at your earliest convenience
to schedule a meeting to further discuss this proposed permit.

A. MANAGEMENT REQUIREMENTS
1. Change in Discharge
All discharges authorized herein shall be consistent with the terms and
conditions of this permit. The discharge of any pollutant identified
in this permit more frequently than or at a level in excess of that
authorized shall constitute a violation of the permit. Any anticipated
facility expansions, production increases, or process modifications which
will result in new, different, or increased discharges of pollutants must
be reported by submission of a new NPDES application or, if such changes
will not violate the effluent limitations specified in this permit, by
notice to the DEM of such changes. Following such notice, the permit
may be modified to specify and limit any pollutants not previously limited.
2. Non compliance Notification
If, for any reason, the permittee does not comply with or will be unable
to comply with any effluent limitation specified in this permit, the per-
mittee shall provide the Division of Environmental Management with the
following information, in writing, within five (5) days of becoming aware
of such condition:
a. A description of the discharge and cause of noncompliance; and
b. The period of noncompliance, including exact dates and times; or,
if not corrected; the anticipated time the noncompliance is expected
to continue, and steps being taken to reduce, eliminate and prevent
recurrence of the noncomplying discharge.
3. Facilities Operation
The permittee shall at all times maintain in good working order and
operate as efficiently as possible all treatment or control facilities
or systems installed or used by the permittee to achieve compliance with
the terms and conditions of this permit.
4. Adverse Impact
The permittee shall take all reasonable steps to minimize any adverse
impact to navigable waters resulting from noncompliance with any effluent
limitations specified in this permit, including such accelerated or
additional monitoring as necessary to determine the nature and impact of
the noncomplying discharge.
5. Bypassing
Any diversion from or bypass of facilities necessary to maintain compliance
with the terms and conditions of this permit is prohibited, except (i) where
M8&I7

unavoidable to prevent loss of life or severe property damage, or
(ii) where excessive storm drainage or runoff would damage any
facilities necessary for compliance with the effluent limitations
and prohibitions of this permit. The permittee shall promptly
notify the Water Quality Section of DEM in writing of each such
diversion or bypass.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the
course of treatment or control of wastewaters shall be disposed of 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.
7. Power Failures
In order to maintain compliance with the effluent limitations and
prohibitions of this permit, the permittee shall either:
a. In accordance with the Schedule of Compliance contained in Part I,
provide an alternative power source sufficient to operate the waste-
water control facilities;
or, if such alternative power source is not in existence, and no date for
its implementation appears in Part I,
b. Halt, reduce or otherwise control production and/or all discharges
from wastewater control facilities upon the reduction, loss, or
failure of the primary source of power to said wastewater control
facilities.

Part II - 7FSCRIPTION OF PROPOSED TREATMENT WORKS
The Company has two (2) discharges of cooling water which are supposedly
uncontaminated. However, results of samples taken on March 10, 1973
indicated a high BOD5 in each of the discharges. Upon being notified
of the results of our samples, the Company began a study to determine
what could be done to prevent the cooling water from becoming contaminated.
The Company also studied the possibility of eliminating anu/or treating
the discharges. The Company has submitted a proposal whereby they plan
to route Discharge 001 and Discharge 002 into one side of their emergency
spill basin and treat all of the wastewater in their existing 30,000 gpd
pretreatment system during .ry weather. However, during heavy rainfall
periods, all of the surface water which runs off of the tank farm area
drains into the drainage ditches which carry the two discharges. There-
fore, during some heavy rainfall periods, a discharge to the surface
waters will be necessary; however, as much of the runoff as possible will
be contained and treated. Any water which is discharged should be
relatively uncontaminated surface runoff.

The Company submitted a time schedule for the implementation of the
proposed plan and has projected a date of April, 1979, for completion
of the plan. It is recommended that a p�,rnit be issued for the continued
discharge of the existing discharges and for the intermittent discharge
after the proposal is implemented.
