Dear Mr.Hoover:
Our records indicate that NPDES Permit No. NC0081744 was issued on April 15, 2002 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 are Pages 4 and 5.
Pages 4 and 5 set forth the effluent limitations and monitoring requirements for your
discharge. Your discharge must not exceed any of the limitations set forth, The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations, Upon commencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved by this
Agency. If you have not received these forms, they should be arriving shortly. If you fail to receive
the forms, please contact this Office as quickly as possible. I have enclosed a sample of the "Effluent"
reporting form (DWQ Form MR-1), plus instructions for completing the form. It is imperative that
a applicable parts be completed, and the origin& and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be required
for your facility. You will soon be receiving a statement from our Raleigh Office. It is imperative
that the fee be paid in a timely manner so as to prevent enforcement action or possible revocation of
your permit
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment facilities, Any changes in operation of wastewater

treatment facilities, quantity and type of wastewater being treated or discharged, expansions and/or
upgrading of wastewater treatment facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects the Permittee
to enforcement action pursuant to Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to $25,000 per violation (and/or criminal penalties) may be assessed for such violations.
If you find at any time that you are unable to comply with the terms and conditions of the Permit, you
should contact this Office immediately. A Special Order by Consent (SOC) may be necessary while
pursuing action to obtain compliance.
As a final note, an NPDES Permit is normally issued for a five-year period. Permits are not
automatically renewed. Renewal requests must be submitted to this Agency no later than 180 days
prior to expiration. Please make note of the expiration date of your Permit. This date is set forth on
Page 1 of the Permit. Also note that NPDES Permits are not automatically transferable. If you, as
the Permittee, cease to need this Permit, then you should request that the Division of Water Quality
rescind the Permit or request that DWQ reissue the Permit to another party, if necessary,
As mentioned previously, the purpose of this letter is to advise you of the importance of your
NPDES Permit. Please read the Permit and contact this Office at 704/663-1699 in Mooresville if you.

Dear Mr. Iloover:
APP 2 2 2002
Division personnel have reviewed and approved your application for renewal of the
subject permit. Accordingly, we are forwarding the attached. NPDES discharge 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 U.S..
Environmental Protection Agency dated May 9, 1994 (or as subsequently amended.)
The following modifications have been made to the permit:
Effluent monitoring for tetrachloroethane has been deleted since the volatile
organic compound is no longer present in the effluent. Data from analytical tests
show that neither 1,1,1,2 tetrachloroethane nor 1,1,2,2 tetrachloroethane have
been detected in the effluent.
«� Effluent monitoring has been added for tetrachloroethylene. D.R. Hoover has
been monitoring for tetrachloroethylene for several years, although it was not
specified in the permit.
• The effluent limit for trichloroethylene has been eliminated however monthly
effluent monitoring will be continued.
The NPDES Unit has been informed that D.R. Hoover has not discharged
from the groundwater remediation project since January 2001, and that the project
will start pumping again in 2002. For future reference, Division of Water Quality
(DWQ) requests immediate notification when pumping is ceased. In addition, if it
seems that permanent cessation will occur, DWQ Compliance Unit should be
contacted so that permit rescission efforts can be initiated.
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

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1 Permit Issuing Authority: The Director of the Division of Water Quality.
2. DEM or the Divisi n" Means the Division of Water Quality, Department of Environment and Natural
Resources,
3. EMC Used herein means the North Carolina Environmental agement Commission.
4. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended,

Mass/Day Measurements
6.
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
dischar s 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 tneasured, 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 1 of the
permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar year on which daily discharges are 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.
ea
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 1 of the permit.

Part II
Page 2 of 11
6. 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.
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 inonitored continually
except for the infrequent times when there may be no flow or for infrequent maintenance activities on the
flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and
combined proportional to the rate of flow measured at the time of individual sample collection, or

Part II
Page 3 of 11
8. a. (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
mav 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
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 (I).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concernration 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.
1 . 1 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 3070)(1) of the Clean
Water Act.
SECTION B. GENERA". CONDITIONS
I, Duty to Comply

4. Bypassing of Treat Facilities
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 Toss caused by delays in production.

Part II
Page 7 of 11
4. 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 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 permitte
for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury car 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 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 per
upset has the burden of proof.

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.

6. Concentration Measurement
a. The "'average monthly concentration, other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sarnple 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 bacteriais 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,
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 1 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.
The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
A calendar quarter is defined as one of the following distinct periods January through March,
April through June, July through September, and October through December.

Other Measurments
a. Flow, (MGD): The flow lirnit 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 samp ing, when
both the sample and flow will be representative of the total discharge.
c. A °continuous flow measurement'" is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge
and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow
recorder and totalizer, and the present gallon interval between sample collection fixed at
no greater than 1/24 of the expected total daily flow at the treatrnent 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).
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.

4. Bypassing of Treatment Facilities
a Definitions
(I) "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

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 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. (I) of this section.

Part II
Page 9 of 1.4
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.

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 regulations
governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued
by the Permit Issuing Authority for the utilization/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 requirement. The permittee shall notify the Permit Issuing
Authority of any significant change in its sludge use or disposal practices.
7. Power Failures
The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation,
Title ISA, North Carolina Administrative Code, Subchapter 2H, .0124 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.

this letter is to advise you of the importance of the Permit and
the liabilities in the event of failure to comply with the terms
and conditions of the Permit. If you have not already done so, it
is suggested that you thoroughly read the Permit. Of particular
importance is Page 4.
Page 4 sets forth the effluent limitations and monitoring
requirements for your discharge(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 forms, please contact this Office as quickly as
possible. I have enclosed a sample of the "Effluent" reporting
form (DEM Form MR-1), plus instructions for completing the form.
It is imperative that all applicable parts be completed, and the
original and one copy be submitted as required.

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 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

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..

Pan II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of
the concentrations of all daily discharges sampled and/or measured during a calendar month
on which daily discharges are sampled and measured, divided by the number of daily
discharges sampled and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in
Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of
the daily concentration values). The daily concentration value is equal to the concentration
of a composite sample or in the case of grab samples is the arithmetic mean (weighted by
flow value) of all the samples collected during that calendar day. The average weekly count
for fecal coliform bacteria is the geometric mean of the counts for samples collected during
a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sarnple 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.
g.
The "quarterly average concentration" is the average of all samples taken over a calendar
quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit.
A calendar quarter is defined as one of the following distinct periods: January through
March, April through June, July through September, and October through December.

ent
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 atpling,
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 facilityw Flow
shall be monitored continually except for the infrequent times when there may be no flow
or for infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of
discharge and combined proportional to the rate of flow measured at the time of
individual sample collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the
sampling point. Flow measurement between sample intervals shall be determined by
use of a flow recorder and totalizer, and the present gallon interval between sample
collection fixed at no greater than 1/24 of the expected total daily flow at the treatment
system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of
flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
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 trust 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 analog 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 11
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration tunes 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.
. Hazardous Substance
A hazardous substance means any substance designated under 40 + rR Part 116 pursuant to
Section 311 of the Clean Water Act.
2. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under Section 3i(a)(1) cif ilia Clean Water Act.

(C) The perrnittee 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 perrnittee 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 perrnittee facility was at the time being properly operated; and

Time Schedule for RAP
Phase I. We will immediately (within 15 days) put everything
in motion after receiving permits and proposal acceptance. An
air stripper will be ordered upon notification, but the delivery
time will be two to three months and this time will fluctuate
dependent on the economy, which possibly could go to a maximum of
six to 12 months delivery.
Regardless of when permits arrive, proposal acceptance is made, and
the delivery of the air stripper is made, Hoover Machine will
immediately begin work (pursuant to the commission's rules) on
whichever phase that is possible to work on.
Phase II. Every six months, we will evaluate the progress made
and decide if a five-year clean-up is feasible. If not, we will
step up the gallons per minute, if recovery permits.

4. Air Quality and/or Groundwater concerns or hazardous waste
utilized at this facility that may impact water quality, air
quality or groundwater? The proposed wasteflow is generated
from a groundwater recovery system. The groundwater in the
area where Hoover Machine Company is located is contaminated
with Trichloroethylene (TCE). Severe toxic effect concen-
tration of TCE for man by inhalation is 10,940 mg/cubic
meter/60 min. LC50 for freshwater fathead minnow by ingestion
is 40.7 mg/l. TCE is also considered as carcinogenic.
Proper treatment to remove TCE from the recovered groundwater
prior to discharging may prevent any impact on surface water
quality. The Air Quality and Groundwater sections may wish to
comment on this project.
5. Other: N/A
PART IV - EVALUATION AND RECOMMENDATIONS
Hoover Machine Company proposes to discharge an undetermined
amount of treated groundwater to an unnamed tribuatry to Catawba
Creek. The groundwater in the area where the Company is located
has been contamined with trichloroethylene (TCE). A water supply
well of a home owner located downgradient was contaminated.
A Special Order by Consent (SOC) was issued to the subject
facility on November 15, 1991 by the North Carolina Environmental
Management Commission. Under the SOC (EMC GW #91-28) a ground-
water recovery system will be constructed to de -contaminate the
affected groundwater in that area.
A Cascade Air Stripper (by Ejector Systems, Inc.) will be
used at the site to remove volatile organic compounds from the
recovered groundwater. Chemical Precipitation to reduce metals

r
centrations from the recovered groundwater prior to discharge
ld be used should it become necessary.
A significant amount of flow was observed in the designated
receiving stream on the day of the investigation. However, this
flow may be due to recent rain events in that region. Thus, it
is necessary to verify that the receiving stream meets 7Q10 or
30Q2 flow criteria prior to the issuance of an NPDES Permit.
It is recommended, pending final review and concurrence by
the State Review Group, the Air Quality and Groundwater Sections,
that an NPDES discharge Permit be issued to the applicant as
requested.

D. R. Hoover Inc. is requesting renewal of an existing NPDES permit discharging from the
Hoover Machine Company to the receiving stream, UT Catawba Creek. The permit is for a
groundwater remediation project for discharge of solvents, trichloroethylene, and
tetrachloroethylene. The design capacity of the facility is 0.072 MGD.
**Per memo in DMR files, DENR granted D.R. Hoover permission to shut down the groundwater
recovery system for one year (per memo Dec. 6, 2000). The system was shut down on January
23, 2001, no DMRs have been submitted since then. They anticipate being shut down through
2001. Talked with Chuck Pippen, a hydrogeologist in the Groundwater Section, MRO who sent
the letter to D.R. Hoover to allow the shutdown after the facility sent supporting data to show
that TCE was decreasing. Facility is to send in bi-annual sampling data in Dec. 2000, June
2001 and Dec. 2001. He said that facility indicating that tetrachloroethane was present in
groundwater was a mistake, because there has only been tetrachloroethylene in the monitoring
wells. Will fax a copy of the letter and annual monitoring report for our records. He also
indicated that facility would still need the NPDES permit because they intended to start up the
pumping again in 2002.
Catawba Creek (and tributaries) is listed on the North Carolina 2000 303(d) list, from source to
Lake Wylie with potential sources of urban runoff/ storm sewers and municipal point sources.
Hoover Machine discharges into a tributary in a segment rated not supporting (from SR2439 to
Lake Wylie). The Catawba Creek arm of Lake Wylie is not impaired, however DWQ is concerned
about eutrophication of this arm of the lake. About 300 acres of the Catawba Creek arem are
rated fully supporting but threatened. The major municipal discharger, Gastonia -Catawba
Creek WWTP, was decommissioned in 1999 and no longer discharges. The use support rating
for Catawba Creek is partially supporting from the source to SR2446 and not supporting from
SR 2446 to Lake Wylie.
The fish community assessment for Catawba Creek was rated Poor at SR2435 in Gaston
County in 5/97,

Existing Effluent Limits
Qw = 0.072 MGD
Trichloroethylene (TCE) = 1185 ug/1
Monthly monitoring for tetrachloroethane
NC standard for TCE is 92.4 ug/1, 1,1,2,2 tetrachloroethane is 10.8 ug/1, both for human
health standard. The NC standard for tetrachloroethylene of 0.8 ug/1 is only for WS class
waters (UT Catawba Creek is class C, therefore the standard would not apply.)
A review of the daily monitoring report indicated that facility monitored for TCE and PCA
(tetrachloroethane) and/or PCE (tetrachloroethylene) in 1997. Data from 1998 through 2001,
shows the facility monitoring for TCE and tetrachloroethylene not tetrachloroethane. There is
no documentation of the facility requesting a change in parameter monitoring from DWQ,
TOXICITY TESTING:
None Required, l00%© industrial
COMPLIANCE SUMMARY:
January through February 2001, Avg. Qw = 0. 018 MGD (approximately 25% of capacity)
In 2000, Avg. Qw = 0. 0145 MGD (approximately 24% of capacity).
In 1999, Avg. Qw = 0. 0179 MGD (approximately 25% of capacity).
In 1998, Avg. Qw = O. 018 MGD (approximately 25% of capacity).
In 1997, Avg. Qw = O. 0169 MGD (approximately 23% of capacity).
REASONABLE POTENTIAL ANALYSIS:
Analysis was conducted using discharge monitoring report (DMR) data from 1999, 2000 and
2001. The parameters that were analyzed were trichloroethylene, tetrachloroethane and
tetrachloroethylene.
• It was determined that a reasonable potential did not exist for trichloroethylene (TCE) to
exceed the water quality standard. Therefore will eliminate the limit, however, because
pump has been shut down for twelve months and will start up within next few months will
recommend that monthly monitoring remain in the permit to see what levels of TCE
are still in the wells.
• It should be noted that there were not enough data values for tetrachloroethane to conduct
a valid RPA. All five values were below detection. Also based on information from GW that
report of tetrachloroethane presence was in error, will recommend that tetrachloroethane
monitoring be removed from the permit.
• Tetrachloroethylene (PCE) was evaluated, although the WQ standard is effective only for WS
class streams. Because is a carcinogen, and facility clearly discharges, will recommend
monthly monitoring until system shuts down permanently.
INSTREAM MONITORING:
None Required
PROPOSED CHANGES:
The following modifications have been made to the permit:
• The deletion of effluent monitoring for tetrachloroethane. Permittee indicates that
the volatile organic compound is no longer presence in the effluent, Data from four
analytic tests in 1999 show that neither 1,1,1,2 tetrachloroethane, nor 1,1,2,2
tetrachloroethane have been detected in the effluent.
Addition of an effluent monitoring for tetrachloroethylene. Facility has been
monitoring for tetrachloroethylene for several years, although it was not specified in
the permit.
• Elimination of limit for trichloroethylene (TCE), however will recommend that
monthly monitoring remain in the permit..

Dear Mr. Hoover:
NOV 2
The Division has reviewed your NPDES permit application for D. R. Hoover, Inc.
and has drafted a NPDES permit for the facility. The draft permit authorizes D. R.
Hoover, Inc. to discharge up to 0.072 MGD of treated wastewater from a groundwater
remediation project into an UT Catawba Creek, a class C water in the Catawba River
Basin. The permit includes discharge limitations for flow, trichloroethyl.ene and
tetrachloroethylene. The following modifications have been made to the permit:
The deletion of effluent monitoring, for tetrachloroethane due to evidence that the
volatile organic compound is no Longer presence in the effluent. Data from
analytic tests show that neither 1,1,1,2 tetrachloroethane, nor 1,1,2,2
tetrachloroethane have been detected in the effluent.
The addition of an effluent monitoring for tetrachloroethylene. D.R. Hoover has
been monitoring for tetrachloroethylene for several years, although it was not
specified in the permit.
The elimination of an effluent limit for trichloroethylene however will recommend.
that monthly effluent monitoring be continued.
The NPDES Unit has only recently been inforrned that D.R. Hoover has not
discharged from the groundwater remediation project since January 2001., and that
the project will start pumping again in 2002. For future reference, DWQ requests
immediate notification when pumping is ceased. In addition, if it seems that
permanent cessation will occur, DWQ compliance unit should be contacted so that
permit rescission efforts can he initiated.
At this time, the Division is submitting a notice to the newspapers of general
circulation in Gaston County, inviting public comment on the draft permit. The notice is
scheduled to be published on or about November 14, 2001. Following a 30-day comment
period, we will review all pertinent comments received and take appropriate action on the
permit renewal.

PERMIT
The permit for the subject facility became effective on November I, 1996, and expires at
midnight on September 30, 2001. Inspection of the facility verified the facility description.
FACILITY SITE REVIEW/OPERATIONS AND MAINTENANCE:
The permitted facility is a non -classified (0.072 MGD) groundwater remediation facility
which consists of recovery well, pump, flow meter with totalizer, and cascade aeration.
RECORDS AND REPORTS:
Records and reports were available for review in the facility's office, The operator maintains
a visitation log.
SELF -MONITORING PROGRAM:
Self -monitoring reports were reviewed for the period August 1998 through September 1999,
inclusive. There were no reported limit violations during the review period, Monitoring appears to
be conducted according to permit requirements.
LABORATORY:
The subject facility is utilizing Specialized Assays, Inc. (Certification #387) of Nashville,
Tennessee, to perform sample analyses. A review of the chain -of -custody (COC) forms indicate that
samples are being properly preserved and are meeting required holding times.
FLOW MEASUREMENT:
The flow is measured by means of an in -line flow meter with totalizer. The flow meter
appeared to be operating properly at the time of the inspection. Although the permit only requires
that flow be measured by an instantaneous method, the use of a flow meter is permissible. If the
flow meter is used for effluent flow measurement it must be calibrated annually and the calibration
documented.
EFFLUENT/RECEIVING STREAM:
At the time of the inspection the effluent was clear with no detectable odor, suspended solids,
or foam at the point of discharge. The receiving stream was turbid from a recent rain event and it
was not possible to determine if the discharge was having a negative impact on the receiving stream.

Subject: Relaxation of monitoring requirements
NOTES/ SUMMARY
Hoover had spill of trichloroethylene and tetrachloroethane in l ite'805 or early'9©s and are doing GW
rernediation at the site (pump and treat). Concentrations of the organics in the recovery well have
steadily declined and are consistently less than 100 ug/L each now. Since this is a 'mom and pop'
business, and since the organics conc, are steady and declining, would like to reduce the monitoring
frequency to 1/qtr or 2/yr to lighten the financial load on the business. Made similar argument before
and reduced frequency from 2/mo to 1/mo.
loid JH the argument Sounds reasonable, that we would need formal request w/ supporting data and
justification in order to consider it. Told him i still need to see if there is any precedent, policy, or
regulation that would prevent u5 from approving the request. He asked me to check this out before he
incurs an expense for the permittee in preparing the request.
F Jeff Hollis, 6/7/99, 1500 hrs.:
Follow-up call from JH. Told him we would consider reducing monitoring frequency if analysis of their
monitoring data indicates no reasonable potential to exceed permit limit. i ue to workload right
now, may not get to it before permit renewal in Sep©1. If he did the RF' analysis and submitted it
to us, it would save us that time and improve the chances of a timely permit mod - but no
guarantees.
Agreed to send him a copy of the l<F analysis procedures we use, along w/ a spreadsheet for the
calculations.
NEEDED FOLLOW-UP ACTION(S)
1. Check on possibility of reduced monitoring, when
Pave returns next week.
2. Send reasonable potential analysis guidance.
