Dear Ms. Martin/Mr. Stover:
Division staff has confirmed that the subject permit is no longer required. Therefore, in
accordance with your request, NPDES Permit NC0069175 is rescinded, effective immediately.
If in the future your community wishes to discharge wastewater to the State's surface waters, you
must first apply for and receive a new NPDES permit. Discharge of wastewater without a valid
NPDES permit will subject the responsible party to a civil penalty of up to $25,000 per day.
If you have questions about this matter, please contact Charles Weaver of my staff at the
telephone number or address listed below.

Dear Mr. Hayes:
•
Our records indicate that NPDES Permit No. NC0069175 was issued on September 13,
2005 for the discharge of wastewater to the surface waters of the State from your facility. The
purpose of this letter is to advise you of the importance of the Permit and the liabilities in the
event of failure to comply with the terms and conditions of the Permit. If you have not already
done so, it is suggested that you thoroughly read the Permit. Of particular importance is Page 4.
Page 4 sets forth the effluent limitations and monitoring requirements for your discharge.
Your discharge must not exceed any of the limitations set forth. The section headed
"Monitoring Requirements" describes the measurement frequencies, sample types and sampling
locations. Upon commencement of your discharge (or operation), you must initiate the required
monitoring. The monitoring results must be entered on reporting forms furnished or approved by
this Agency. For new permits/facilities,the Division may supply an initial small stock of these
forms; however, if you fail to receive the forms,please contact this Office as quickly as possible.
The forms, including directions for their completion, and other important information are also
available at http://h2o.enr.state.nc.us/NPDES/documents.html. It is imperative that all applicable
parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual fee may be required for your facility; if so, you will
receive a statement from our Raleigh Office. It is imperative that the fee be paid in a timely
manner so as to prevent enforcement action or possible revocation of your permit.
The remaining parts of the 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.
To maintain compliance with discharge limitations,proper operation and maintenance of
a wastewater treatment facility and the development of a process control program are essential.
For those facilities having chlorine tablet disinfection,please be advised that chlorine tablets
approved for wastewater treatment use must be used; swimming pool tablets are not approved.
Also, be advised that DWQ staff need to have access to the facility's discharge point into the
receiving stream; please maintain a path along the outfall line to facilitate that access.
Failure to comply with the terms and conditions of an NPDES Permit subjects the
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 have any questions or need clarification. We look forward to providing any
assistance.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,33 USC 1251,et. seq.
Annual Average
The arithmetic mean of all "daily'discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
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.
Calendar Day
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.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: 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
(3) Variable time/constant volume: 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 preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system,or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.
Version 6J22012003

NPDES Permit Requirements
Page 2 of 16
In accordance with (4) above,influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more 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
intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs 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.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest"daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWQ or"the Division"
The Division of Water Quality,Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission.
Facility Closure
The cessation of wastewater treatment at a permitted facility,or the cessation of all activities that require coverage
under the NPDES. Completion of facility closure will allow this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean,values of"0" (or"< [detection level]") shall be considered=1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
Instantaneous flow measurement
A measure of flow taken at the time of sampling,when both the sample and flow will be representative of the total
discharge.
Version 6J20/2003

NPDES Permit Requirements
Page 3 of 16
• Monthly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform, the geometric mean of such discharges.
Permit Issuing Authority
The Director of the Division of Water Quality.
Quarterly Average (concentration limit)
The average of all samples taken over a calendar quarter.
Severe property damage
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 excludes economic loss caused by delays in production.
Toxic Pollutant:
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
Upset
An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with
permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by
operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive
maintenance,or careless or improper operation.
Weekly Average (concentration limit)
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar week. In the case of fecal
coliform, the geometric mean of such discharges.
Section B. General Conditions

PART III- OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grant Funds or are any public monies
involved(municipals only)? Public monies were not used in the construction of this
facility.
2. Special monitoring or limitations (including toxicity)requests: Per current Division
policy, this facility will have a Total Residual Chlorine limit added to the permit upon
renewal.
3. Important SOC, JOC or Compliance Schedule dates: This facility is neither under an SOC
nor is one being proposed at this time. The renewed permit will contain a schedule that
will allow the permittee up to 18 months in which to have dechlorination facilities
approved and installed.
4. Alternative Analysis Evaluation: The permittee continues to explore the option of
connecting this facility to a POTW. The City of Gastonia has a sewer line less than a
mile from the site, however, it is currently cost prohibitive for the permittee to construct a
line that would connect to the City's line. The permittee is looking into the possibility of
applying for some type of grant to augment the cost of constructing a line that will
connect to the City.
PART IV- EVALUATION AND RECOMMENDATIONS
The permittee is applying for renewal of its permit to discharge treated domestic
wastewater into an unnamed tributary to Blackwood Creek. There have been no changes to the
permit and/or the WWTP since the permit was last renewed. Proposed changes anticipated
during this renewal include the addition of a TRC limit, which will require the construction of
dechlorination facilities unless the facility can cease the discharge or convert to Ultraviolet
disinfection.
Pending a final technical review by the NPDES Unit, it is recommended that the NPDES
Permit for this facility be renewed.

TO: NPDES Unit Staff -
FROM: David A. Goodrich Vel
NPDES Unit Supervisor
SUBJECT: Total Residual Chlorine Policy for NPDES permits
Every three years the State is required by the Clean Water Act to review its surface water quality standards and
classifications,determine if changes are needed and to make any necessary changes. This review process is referred to
as the"triennial review." Public hearings were held to solicit comments for the 2000-2003 Triennial Review of surface
water quality standards during the summer of 2002. The Hearing Officer's recommendations were presented before
the state's Environmental Management Commission on October 10,2002.
The Hearing Officer's recommended changes included modifications to the existing standards for Arsenic,Cyanide,
Methylene Blue Active Substances (MBAS)and Total Residual Chlorine(TRC). The Hearing Officer also
recommended the addition of a standard for Methyl Tert-Butyl Ether(MTBE).
All of the Hearing Officer's proposed changes were adopted with the exception of MTBE. The changes took effect
on April 1,2003. This memo documents the changes to the NPDES permitting policy for TRC limits.
Total Residual Chlorine (TRC)
Previously,TRC had an Action Level Standard,except in designated Trout waters. The Triennial Review changes
modified the TRC Action Level Standard to an Aquatic Life Standard of 17 µg/L The Aquatic Life Standard will
remain for designated Trout waters.
Aquatic Life Standard—17 µg/L (freshwater only) Trout Waters—17 µg/L
Revised TRC Policy
> TRC limits will be assigned to permit renewals and all new permits issued after April 1,2003.
> Facilities that do not use chlorine will not receive a TRC limit;however,the presence of a chlorine back-up
system to augment UV or other disinfection requires a TRC limit.
> Facilities discharging to streams with a 7Q10<0.05 cfs (zero-flow streams)will receive a limit of 17 µg/L.
➢ Limits will be capped at 28 µg/L to protect against acute impacts.
It is likely that many facilities will need to add dechlorination(or use another means of disinfection) to comply with
the new TRC standard. Therefore,a compliance schedule of 18 months from the effective date of the permit may
be added to any TRC limit added during the current permit renewal. This time period is allowed in order for the
facility to budget and design/construct the dechlorination and/or alternative disinfection system(s). The NPDES
Unit has promulgated minimum design criteria in order to expedite permitting of dechlorination equipment.

Subject: NPDES Permit No. NC0069175
Ridge Community WWTP
Gaston County, NC
Dear Mr. Stover:
Our records indicate that NPDES Permit No. NC0069175 was issued on December 7, 2001
for the discharge of wastewater to the surface waters of the State from your facility. The purpose
of this letter is to advise you of the importance of the Permit and the liabilities in the event of failure
to comply with the terms and conditions of the 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 original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be required
for your facility. You will soon be receiving a statement from our Raleigh Office. It is imperative
that the fee be paid in a timely manner so as to prevent enforcement action or possible revocation of
your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment facilities. Any changes in operation of wastewater
treatment facilities, quantity and type of wastewater being treated or discharged, expansions and/or

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

Dear Mr.Stover
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 information you submitted regarding potential alternatives to discharge was acceptable to the Division. Subsequent
correspondence from the City of Gastonia verified the lack of sewer availability in your area.
Your facility is discharging excessively high amounts of total residual chlorine. The average TRC concentration in
the effluent should be below 28 µg/L. This facility discharged an average of 1,412 µg/L per month in 2000 and 1,544 µg/L
per month in the first half of 2001. Unless these concentrations are reduced,the Division may reopen this permit
and add a chlorine limit.
If any parts,measurement frequencies or sampling requirements contained in this permit are unacceptable to you,you
have the right to an adjudicatory hearing upon written request within thirty(30)days following receipt of this letter. This request
must be in the form of a written petition,conforming to Chapter 150B of the North Carolina General Statutes,and filed with the
Office of Administrative Hearings(6714 Mail Service Center,Raleigh,North Carolina 27699-6714). Unless such demand is
made,this decision shall be final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other
permits which may be required by the Division of Water Quality or permits required by the Division of Land Resources,the
Coastal Area Management Act or any other Federal or Local governmental permit that may be required.
If you have any questions concerning this permit,please contact Charles Weaver at telephone number(919)733-5083,

PART II
STANDARD CONDITIONS FOR NPDES PERMITS .
SECTION A. DEFINITIONS
1. Permit Issuing Authority: The Director of the Division of Water Quality.
2. DEM or"the Division" Means the Division of Water Quality,Department of Environment and Natural
Resources.
3. EMC Used herein means the North Carolina Environmental Management Commission.
4. Act or"the Act" The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,
33 USC 1251,et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during a calendar month on which daily discharges are sampled and measured,divided by the number of daily
discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by
adding the weights of the pollutant found each day of the month and then dividing this sum by the number
of days the tests were reported. The limitation is identified as"Monthly Average"in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided
by the number of daily discharges sampled and/or measured during such week. It is,therefore,an arithmetic
mean found by adding the weights of pollutants found each day of the week and then dividing this sum by
the number of days the tests were reported. This limitation is identified as "Weekly Average"in Part I of the
permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This limitation is identified as"Daily Maximum," in Part 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 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.

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

Part 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
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.
10. Calendar Day: A calendar day is defined as the period from midnight of one day until midnight of the next day.
However, for purposes of this permit,any consecutive 24-hour period that reasonably represents the calendar day
may be used for sampling.
11. Hazardous Substance: A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant: A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1)of the Clean
Water Act.
SECTION B. GENERAL CONDITIONS
1. Duty to Comply
The permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation
of the Clean Water Act and is grounds for enforcement action; for permit termination,revocation and reissuance,
or modification;or denial of a permit renewal application.

Subject: NPDES Permit Renewal Application
Permit NC0069175
Ridge Community Sewer Association
Gaston County
Dear Mr. Stover:
The NPDES Unit received your permit renewal application on April 5, 2001. Thank you for submitting this
package.
The permit renewal for this facility has been assigned to Charles Weaver. This staff member will contact
you if further information is needed to complete the permit renewal. Please note that the NPDES Unit has
several vacant positions. This staff shortage has lasted for over a year and is delaying all permit renewals.
Our remaining permit writers are currently reviewing Authorizations to Construct, speculative limit requests,
major permit modifications and 201 plan updates ahead of permit renewals. This is necessary due to a
variety of factors, including mandatory deadlines in the statutes which govern our program.
If this staff shortage delays reissuance of NC0069175 the existing requirements in your permit will remain
in effect until the permit is renewed (or the Division takes other action). We appreciate your patience and
understanding while we operate with a severely depleted staff. If you have any additional questions
concerning renewal of the subject permit, please contact Charles Weaver at [phone],extension 511.
Sincerely,
UQLQLL1

RE: Request for Permit Renewal
Ridge Community Sewer Association
NPDES Permit no. NC0069175
Dear Ms. Stephens,
This letter is to request renewal of NPDES Permit no. NC0069175. This facility has had no
changes to the treatment scheme since the last permit renewal.
The sludge management plan is as follows: Solids from this system are collected in the 8,000
gallon septic tank and is pumped annually by Liquid Waste Inc. and ultimate disposal is Irwin
Creek WWTP. Charlotte NC. Solids accumulation on the filter beds are raked off and landfilled
according to State Regulations.
In closing I would like to request that the sample prameter conductivity for upstream,
downstream, and effluent be removed from the permit. I also like to request that quarterly Total
Nitrogen and Total Phosphorus sampling requirments be omitted as this system( only 38 homes)
is so small.
Sincerely,
Larry Neal Stover

Subject: NPDES Permit No. NC0069175
Ridge Community WWTP
Gaston County, NC
Dear Mr. Stover:
Our records indicate that NPDES Permit No. NC0069175 was issued on December 7, 2001
for the discharge of wastewater to the surface waters of the State from your facility. The purpose
of this letter is to advise you of the importance of the Permit and the liabilities in the event of failure
to comply with the terms and conditions of the 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
all applicable parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be required
for your facility. You will soon be receiving a statement from our Raleigh Office. It is imperative
that the fee be paid in a timely manner so as to prevent enforcement action or possible revocation of
your permit.
The remaining parts of the Permit set forth definitions, general conditions and special
conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The
conditions include special reporting requirements in the event of noncompliance, bypasses, treatment
unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant
operator if you are operating wastewater treatment facilities. Any changes in operation of wastewater
treatment facilities, quantity and type of wastewater being treated or discharged, expansions and/or

upgrading of wastewater treatment facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES Permit subjects the Permittee
to enforcement action pursuant to Section 143-215.6 of the North Carolina General Statutes. A civil
penalty of up to$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 nat
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 Lot automatically transferable. If you, as
the Permittee, cease to need this Permit, then you should request that the Division of Water Quality
rescind the Permit or request that DWQ reissue the Permit to another party, if necessary.
As mentioned previously, the purpose of this letter is to advise you of the importance of your
NPDES Permit. Please read the Permit and contact this Office at 704/663-1699 in Mooresville if you
have any questions or need clarification. We look forward to providing any assistance.

Subject: Issuance of NPDES Permit NC0069175
Ridge Community WWTP
Gaston County
Dear Mr. Stover:
In accordance with your application dated March 11, 1996. the Division is forwarding the
subject State-NPDES permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the U. S. Environmental Protection Agency dated December 6, 1983.
Please be aware that the subject facility discharges into a stream which is defined as a
"zero-flow stream." During low-flow conditions, zero-flow streams have no naturally occurring
flow. These streams show considerable environmental sensitivity, and the Division has mandated
that existing discharges be removed from such streams if an environmentally superior alternative
is available to the discharger at an economically reasonable cost.
The subject facility has had several permit limit violations within the past year. Because
the facility is in substantial non-compliance with the terms and conditions of the NPDES permit,
and is discharging into a zero-flow stream, you must submit a report evaluating alternatives to this
discharge by May 1, 1997. This report must include an evaluation of connection to the City of
Gastonia Crowders Creek Wastewater Treatment Plant. as well as other non-discharge options,
including moving the outfall to a larger stream with positive flow.
Attached is guidance which you should use in fulfilling this permit requirement entitled
"Guidance for Evaluation of Wastewater Disposal Alternatives". This analysis should be
submitted to the NPDES Group at the address listed below.
If any parts. measurement frequencies or sampling requirements contained in this permit
are unacceptable to you, you have the right to an adjudicatory hearing upon written request within
thirty (30) days following receipt of this letter. This request must be in the form of a written
petition. conforming to Chapter 150B of the North Carolina General Statutes, and filed with the
Office of Administrative Hearings. Post Office Drawer 27447, Raleigh, North Carolina 27611-
7447. Unless such demand is made, this decision shall be final and binding.
Please take notice that this permit is not transferable. Part II. E.4. addresses the
requirements to be followed in case of change in ownership or control of this discharge.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. Permit Issuing Authority
The Director of the Division of Water Quality.
2. DEM or"the Division"
Means the Division of Water Quality, Department of Environment, Health and Natural Resources.
3. FMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC
1251,et.seq.
5. ivlass/Day Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday -Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as 'Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

Part II
Page 2 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week(arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for samples collected during a
calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daily discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day . The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under "Other Limits" in Part 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
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 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.

3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary
to halt or reduce the permitted activity in order to maintain compliance with the condition of this
permit.
4. Bypassing of Treatment 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 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

5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the
reasonable control of the permittee. An upset does not include noncompliance to the extent
caused by operational error, improperly designed treatment facilities, inadequate treatment
facilities, lack of preventive maintenance, or careless or improper operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with such
technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed,contemporaneous operating logs,or other relevant evidence that:
(1)An upset occurred and that the permittee can identify the cause(s)of the upset;
(2) The permittee facility was at the time being properly operated; and
(3)The permittee submitted notice of the upset as required in Part II,E. 6. (b)(B) of this permit.
(4) The permittee complied with any remedial measures required under Part II, B. 2. of this
permit.
d. Burden of proof.
In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has
the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash,or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such
as to prevent any pollutant from such materials from entering waters of the.State or navigable
waters of the United States. The permittee shall comply with all existing federal 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 15A, 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.

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
1. permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Environment, Health and
Natural Resources.
3. EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended. 33
USC 1251, et. seq.
5. Mass/Dav Measurements
a. The "monthly average discharge" is defined as the total mass of all daily discharges
sampled and/or measured during a calendar month on which daily discharges are sampled
and measured, divided by the number of daily discharges sampled and/or measured during
such month. It is therefore, an arithmetic mean found by adding the weights of the
pollutant found each day of the month and then dividing this sum by the number of days
the tests were reported. The limitation is identified as "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled and/or
measured during such week. It is, therefore, an arithmetic mean found by adding the
weights of pollutants found each day of the week and then dividing this sum by the
number of days the tests were reported. This limitation is identified as "Weekly Average"
in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during
a calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found
each day of the year and then dividing this sum by the number of days the tests were
reported. This limitation is defined as "Annual Average" in Part I of the permit.

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

Part II
Page 3 of 14
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.
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 must be
representative of the discharge or the receiving waters.
9. Calculation of Means •
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the
individual values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of
the individual values where N is equal to the number of individual values. The geometric
mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual
values. For purposes of calculating the geometric mean, values of zero (0) shall be
considered to be one (1).

Part II
Page 4 of 14
c. Weighted by Flow Value: Weighted by flow value means the summation of each
concentration times its respective flow divided by the summation of the respective flows.
10. Calendar 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. 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.

facility including the collection system, which is not a designed or established or
operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to
the treatment facilities which causes them to become inoperable, or substantial and
permanent loss of natural resources which can reasonably be expected to occur in the
absence of a bypass. Severe property damage does not mean economic loss caused by
delays in production.
b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to
be exceeded, but only if it also is for essential maintenance to assure efficient operation.
These bypasses are not subject to the provisions of Paragraphs c. and d. of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it
shall submit prior notice, if possible at least ten days before the date of the bypass;
. including an evaluation of the anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as
required in Part II, E. 6. of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action
against a permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property
damage;
(B) There were no feasible alternatives to the bypass, such as the use, of auxiliary
treatment facilities, retention of untreated wastes or maintenance during normal

Part II
Page 9 of 14
periods of equipment downtime. This condition is not satisfied if adequate backup
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass which occurred during normal periods of equipment
downtime or preventive maintenance; and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.
5. Upsets
a. Definition.
"Upset " means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors
beyond the reasonable control of the permittee. An upset does not include noncompliance
to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper
operation.
b. Effect of an upset.
An upset constitutes an affirmative defense to an action brought for noncompliance with
such technology based permit effluent limitations if the requirements of paragraph c. of this
condition are met. No determination made during administrative review of claims that
noncompliance was caused by upset, and before an action for noncompliance, is final
administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset.
A permittee who wishes to establish the affirmative defense of upset shall demonstrate,
through properly sii*ned, contemporaneous operating loss, 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.

has the burden of proof.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or
control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in
a manner such as to prevent any pollutant from such materials from entering waters of the State.
or navigable waters of the United States. The permittee shall comply with all existing federal

Part II
Page 10 of 14
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 15A, 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.
SECTION D. MONITORING AND RECORDS
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the
volume and nature of the permitted discharge. Samples collected at a frequency less than daily
shall be taken on a day and time that is characteristic of the discharge over the entire period
which the sample represents: All samples shall be taken at the monitoring points specified in

Gaston County, NC
Dear Mr. Burrell:
Our records indicate that NPDES Permit No. NC0069175 was
issued on March 18, 1994 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 4-5.
Pages 4-5 set 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.
The remaining Parts of the Permit set forth definitions,
general conditions and special conditions applicable to the
operation of wastewater treatment facilities and/or discharge(s) .
The conditions include special reporting requirements in the event
of noncompliance, bypasses, treatment unit/process failures, etc.
Also addressed are requirements for a certified wastewater
treatment plant operator if you are operating wastewater treatment
facilities. Any changes in operation of wastewater treatment

facilities, quantity and type of wastewater being treated or
discharged, expansions and/or upgrading of wastewater treatment
facilities must be permitted or approved by this Agency.
Failure to comply with the terms and conditions of an NPDES
Permit subjects the Permittee to enforcement action pursuant to
Section 143-215. 6 of the North Carolina General Statutes. A civil
penalty of up to $10, 000 per violation 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
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.

3. EMC:
Used herein means the North Carolina Environmental Management Commission.
4. Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as
amended, 33 USC 1251, et. seq.
5. Mass/Day Measurements
a. The "monthly average discharge: is defined as the total mass of all
daily discharges sampled and/or measured during a calendar month on
which daily discharges are 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 "Daily Average" or "Monthly Average" in Part I of the
permit.
b. The "weekly average discharge" is defined as the total mass of
all daily discharges sampled and/or measured during the calendar week
(Sunday-Saturday) on which daily discharges are sampled and measured,
divided by the number of daily discharges samples and/or measured
during such week. It is, therefore, an arithmetic mean found by
adding the weights of pollutants found each day of the week and then
dividing this sum by the number of days the tests were reported. This
limitation i.s identified as "Weekly Average" in Part _I of the permit.
c. The "maximum daily discharge" i.s the total mass (weight) of a
pollutant discharged during a calendar day. If only olte 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 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.

Part II
Page 12 of 14
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform
bacteria, is the sum of the concentrations of al.l 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" or
"Daily Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria,
is the sum of the concentrations of all daily discharges sampled and/or
measured during a calendar week (Sunday/Saturday) on which daily discharges
are sampled and measured divided by the number of 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. 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.

Part II
Page 13 of 14
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.
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.

Part II
Page 14 of 14
10. Calendar Day
A calendar day is defined as the period from midnight of one day until midnight
of the next day. However, for purposes of this permit, any consecutive 24-hour
period that reasonably represents the calendar day may be used for sampling.
11. Hazardous Substance
A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant
A toxic pollutant is any pollutant listed as toxic under: Section 307(a)(1) of
the Clean Water Act.

PART III - OTHER PERTINENT INFORMATION
1. Is this facility being constructed with Construction Grants Funds
(municipals only)? n/a
2. Special monitoring requests: n/a
3. Additional effluent limits requests: n/a
PART IV - EVALUATION AND RECOMMENDATIONS
The existing wastewater treatment facilities currently being operated by
Ti-Caro, Inc. are part of a wastewater treatment system built in the 30's or
40's and which was designed to serve a textile mill and nearby mill village.
Over the years ownership of the mill changed hands several times until Ti-Caro
bought the mill, which was then named the Ridge Manufacturing Plant. In May of
1985, Ti-Caro sold the mill to S. C. Downey Construction Co. who used the mill
to construct pre-fabricated roof trusses. S. C. Downey has since closed the
roof truss operation and their future plans for the building are unknown to Ti-Caro.
Subsequently, Ti-Caro once again assumed responsibility for operation and maintenance
of the wastewater treatment facilities because many of their employees continued
to live in the mill village. According to information supplied by Ti-Caro, approx.
35 single family homes, one church and a mill (closed) are the only facilities
connected to the WWTP. Based on flow projections, the wastewater treatment
facilities may be hydraulically overloaded if the actual design capacity is less
than 0.010 MGD.

iti:
It appeared during the site investigation that Ti-Caro has initiated efforts
to upgrade and maintain the existing facilities. There were, however, some
operational deficiencies which, if corrected, should greatly enhance WWTP
efficiency. The distribution box feeding each sand filter bed was in disrepair.
The inside of the box had deteriorated allowing for unequal flow to enter the sand
filter manifolds. Furthermore, the manifolds appeared to be unlevel which resulted
in poor distribution. Outlet holes on the manifolds were clogged with residue also
preventing poor distribution. The sand appeared to be in good condition and
was well raked. Chlorine was present in the chlorinator which had been
recently installed. Effluent quality appeared excellent.
A WLA has not as yet been received for review by the MRO Staff. The existing
facilities may not be able to comply without additional treatment.
Pending receipt and approval of a WLA, it is recommended that an NPDES
Permit be issued. If WLA indicates that a septic tank-sand filter system
cannot meet the limits, then Permit should provide for construction of facilities
necessary to meet the limits.

* Ti-Caro, Inc. is engaged in the business of manufacturing
yarn, thread and knit fabrics. It has approximately 5,200 total
employees. These employees work at numerous plant sites located
both within and outside of North Carolina.
Ti-Caro , Inc . is not currently, nor will it be in the
future, engaged in any manufacturing operation which discharges
into this facility. Ti-Caro, Inc. sold the manufacturing plant
( formerly known as the Ridge Manufacturing Plant) it owned which
discharged into this facility to S . C. Downey Construction
Company, Inc. in May of 1985. The discharge that goes into this
facility comes from the following listed sources:
1. Approximately 35 single-family dwellings;
2. The South Gastonia Pentecostal Holiness Church ( 3
commodes and 3 lavatories) ;
3. The S. C. Downey Construction Company, Inc. plant.
Until approximately two months ago, S. C. Downey Construc-
tion Company, Inc. , or a subsidiary thereof, was constructing
pre-fabricated roof trusses at the location which discharges into
this facility. This operation has now been closed, and S. C.
Downey Construction Company, Inc. ' s future plans for the site are
unknown to Ti-Caro, Inc. When the Ridge Manufacturing Plant was
operating, it did not discharge any industrial waste into this
facility.
** In the past, the sanitary waste has been treated by means of
an above ground sand filter system. Ti-Caro , Inc . is in the
process of installing a wastewater chlorinator to supplement the
treatment provided by the sand filter system.

Subject: NPDES PERMIT NO. NC0069175
GASTON COUNTY
Dear Permittee:
The subject permit issued on 7/20/88 expires on 6/30/92. North Carolina
General Statute (NCGS) 143-215. 1(c) requires that an application for permit renewal
be filed at least 180 days prior to the expiration date. As of the date of this
letter, the Division of Environmental Management had not received an application for
renewal.
If operation of a discharge or waste treatment facility is to occur after the
permit's expiration date, or if continuation of the permit is desired, it must not be
allowed to expire. A renewal request must be submitted no later than 180 days prior
to the permit's expiration date. Operation of the waste treatment works or
continuation of a discharge after the expiration date would constitute a violation of
NCGS 143-215. 1 and could result in assessment of civil penalties of up to $10,000 per
day. If continuation of the permit is desired, failure to request renewal at least
180 days prior to expiration will result in a civil assessment of at least $300.00;
larger penalties may be assessed depending upon the delinquency of the request.
A renewal application shall consist of a letter requesting permit renewal along
with the appropriate completed and signed application form (copy attached), submitted
in triplicate, referenced in Title 15 of the North Carolina Administrative Code (15
NCAC) Subchapter 2H .0105(a). Primary industries listed in Appendix A of Title 40 of
the Code of Federal Regulations, Part 122 shall also submit a priority pollutant
analysis in accordance with Part 122.21. A processing fee must be submitted with the
application. In addition to penalties referenced above, a permit renewal request
received after the expiration date will be considered as a new application and will
require the higher application fee.

� . '11►
Attached is a copy of the fee schedule from 15 NCAC 2B.0105(b) . The application
processing fee is based on the design or permitted flow, whichever is appropriate,
listed in the first five' categories of facilities. Presently, no facility is allowed
to submit a fee for the general permits listed in the schedule since the Environmental
Protection Agency has not approved the State of North Carolina's general permit. If
the facility covered by this permit contains some type of treatment works, a narrative
description of the sludge management plan must be submitted with the application for
renewal.
The Environmental Management Commission adopted revised rules on October 1, 1990
(attached), requiring the payment of an annual fee for most permitted facilities. You
will be billed separately for that fee (if applicable), after your permit is approved.
The letter requesting renewal, the completed Permit application, and appropriate
fee should be sent to:
Permits and Engineering Unit
Division of Environmental Management
Post Office Box 29535
Raleigh, North Carolina 27626-0535
The check should be made payable to the North Carolina Department of Environment,
Health, and Natural Resources which may be abbreviated as DEHNR.
If there are questions or a need for additional information regarding the permit
renewal procedure, please contact me at telephone number (919) 733-5083.

Dear Mr. Gibson:
•
Our records indicate that NPDES Permit No. NC 0069175 was
issued on July 20 , 1988 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 DMR
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,
otherwise the forms may be returned to you as incomplete.
Failure to properly complete the forms may also result in an
automatic $300.00 fine.

Page Two
July 26, 1988
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 day per violation plus
criminal penalties may be assessed for such violations.
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: NPDES Permit No. NC 0069175
Ti-Caro, Inc.
Gaston County, NC
Dear Mr. Myers:
Our records indicate that NPDES Permit No. NC 0069175 was
issued on July 17, 1987 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 DMR
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,
otherwise the forms may be returned to you as incomplete.
Failure to properly complete the forms may also result in an
automatic $300.00 fine.
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 day per violation plus
criminal penalties may be assessed for such violations.
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, through cessation of the discharge, 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.
