'Reference is made to your October 30, 2001 request for rescission of the subject NPDES Perrnit
and other communication you have made with this office regarding this matter. In your letter, you stated
that your company is no longer in business and that groundwater remediation with surface water
discharge is no longer occurring at the site, Staff of the Mooresville Regional Office have confirmed that
this permit is no longer required. Therefore, in accordance with your request., NPDES Permit NC0083461
is rescinded, effective immediately.
Please he advised that this action deals specifically with rescission of the permit that regulates
treatment of wastewater and th.e discharge of treated wastewater into surface waters. It in no way
absolves your company of its responsibility to remediale groundwater contamination associated with the
subject. facility or to comply with applicable environmental law.
If in the future you wish to again discharge wastewater to the States surface waters, you must
first apply for and receive a new NPDES 'Permit. Operating. a facility without a valid NPDES Permit will
subject the responsible party to a civil penalty of up to $25,000 per day.
It you have questions about this matter, please contact Bob Sledge at [phone], extension
547 or the Water Quality staff in our Mooresville Regional Office at (7(4) 663-1699.

Dear Ms. McPherson:
Thank you for the time that you spent with me over the telephone on Monday, October
29, 2001. As 1 mentioned Ace Chemical Corporation is no longer in business. We ceased
operations in late 1995. Since then we have removed all bulk storage tanks, piping and.
other equipment. In 1996 we worked with the City of Charlotte to shut down our
wastewater treatment system. Currently we are utilizing a local real estate firm to either
lease or sell our facility.
I am enclosing the invoice regarding the Annual Permit Fee. Please remove us from the
list of companies that require a permit. If necessary I could easily meet someone from.
your office at the plant to verify the information contained in this letter. My telephone
number in Charlotte is 704-552-5329.
I appreciate your help in this matter.

4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as an ended. 33
USC 1251, et. seq.
L lasspav'eSeasuremenu
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 dischar,e'� 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
b. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sure 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 sarnples 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 coliforrn bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunda)'/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 "Niaxirnum Daily Concentration". It is identified as
"Daily Maxmum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliforrn 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.
The "quarterly average concentration" is the average of all samples taken over a calendar
quaver. It is identified as "Quarterly Average Limitation" in the text of Part 1 of the permit.
A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through September, and October through December.

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.
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.
Types. of SamP1
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
( 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
sarr,plin2 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
e, continuous sample collected over a 24 hour period proportional to the rate of
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. Foi purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

Part I1
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 Dav
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. Nazardous Substanz<r
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.

4. )3vpa"ing of Treatment Facilities
a. Defittitions
(1) "Bypass'" means the known diversion of waste streams from an portion of a treatment
facility including the collection system. which is not a designed or established or
operating mode for the facility.
( ) "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 perrnittee 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 perrnittee knows in advance of the need for a bypass, it

a. De 'on.
"Upset '" rnea.ns 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:
(I) An upset occurred and that the perrninee can identify the causes) of the upset;
(2. The pertruttee 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
