Gaston County, NC
Dear Mr. Avery:
Our records indicate that NPDES Permit No. NC0072109 was
issued on November 25, 1992 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.
Sincerely,

PART IV - EVALUATION AND RECOMMENDATIONS
The applicant, Tryon Park Mobile Home Park, has requested the
renewal of the permit for the discharge of treated domestic
wastewater into Little Beaverdam Creek. As of this date no
construction has begun on this project. There does not appear to
be any site specific problems with this project that would hinder
the reissuance of the permit.
It is recommended that the subject Permit be renewed and
include a provision that an Authorization to Construct be requested
within six months after permit renewal. If the Authorization to
Construct is not requested before the time span specified then the
permit should be voided.

Dear 'Overcash:
Tryon ark is a proposed mobile hone park which encompasses approximately 67 acres
and i located west of U. S. Highway 321 North along Tryon School Road (S.R. 1440)
in Gaston County.
The domestic wastewater from the development will be collected in the sewer collection
system and transported to a 125,000 G.P.D. wastewater treatment plant. The treatment
plant will discharge into a tributary to Little Beaverdam Creek northwest of the
property. A total of approximately 320 homes will eventually be served by this plant.
The extended aeration treatment process shall include screening, aeration, clarification,
chlorination, and post aeration prior to discharge into the stream.
Please review the attached NPDES application, processing fcc and attached sketches.
Should you have any questions, please foci free to contact this office.
Very truly yours,

GENERAL
1 .01 PURPOSE
The purpose of this Preliminary Engineeing Report is to
study the Northwestern Financial Group property and
surrounding area. Water will be obtained from two wells to
be drilled on-site. The wastewater treatment plant will
utilize the extended aeration treatment process and shall
be designed to meet the effluent limits established for
this project by the State of North Carolina Division of
Environmental Management.
1 .02 GENERAL
The Northwestern Financial Group property consists of
approximately 67± acres located in Northern Gaston County.
The land is currently being used as farmland. Construciton
will begin after harvest of this year ' s crop. Up to 350
mobil ? nwmes could be served by this WWTP and would be
phased into the property in either two or three phases.
Septic tanks were originally proposed to serve this
project, however, due to the soil characteristics for this
site, a WWTP is deemed to be the most desirable method for
sewage disposal .
1 .03 RECEIVING STREAM
The receiving stream for the proposed WWTP is a tributary
to Little Beaverdam Creek.
1.14 DESIGN
SEWER COLLECTION SYSTEM. The flow into this Wastewater
Treatment Plant is estimated to be 125,000 gallons per day.
This figure was based upon a maximum of 350 mobile home
sites at 360 gallons per day per site.
An eight-inch sewer collection system will be suitable to
carry the anticipated flow. This sanitary sewer system
shall be private and shall be designed and installed
according to State standards.
1 .05 WASTEWATER TREATMENT PLANT
The wastewater treatment plant shall be a concrete built in
place plant and shall incorporate screening , aerobic
biological treatment, settling, chlorination, post-aeration
and flow measurement . Pumping facilities will be made
available if required by the topography of the site. The
actual volumes for the different parts of this treatment
plant shall be determined by the effluent limits.

1 .06 FLOOD PROTECTION
All of the blowers, electrical controls, and the wastewater
treatment plant shall be protected from flooding and shall
be constructed above to 100 year flood elevation.
1 .07 OWNERSHIP OF WASTEWATER TREATMENT PLANT
Northwestern Financial Group, Inc . has contacted Burnett
Construction Co. , Inc. , DBA Burnett Utilities. Discussions
held on several occasions indicate a workable agreement can
be reached for operations of the wastewater facilities . A
contract will be forwarded with the plans and
specifications for review at the proper time.
1 .08 CONCLUSION
This Wastewater Treatment Plant shall satisfactory and
consistently meet the effluent limits . Once the effluent
limits are established by the State , the wastewater
treatment plant shall be designed and submitted for
Authorization to Construct.

Subject: NPDES Permit No. NC 0072109
Tryon Park Mobile Home Park
Gaston County, NC
Dear Mr. Avery:
Our records indicate that NPDES Permit No. NC 0072109 was
issued on January 11, 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.
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
919 North Main Street, P.O. liox 950, Mooresville, NC. 281150950•Telephone 704663-I*O

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-i
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.
Sincerely,
D. Rex Gleason

TRYON PARK MHP
C/O 4200 BROOKSHIRE BLVD.
CHARLOTTE, NC 28216
Subject: NPDES PERMIT NO. NC0072109
GASTON COUNTY
Dear Permittee:
The subject permit issued on 1/11/88 expires on 12/31/92. 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.

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.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. 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 for denial of a permit renewal application.
2. Penalties for Violations of Permit Conditions
Any person who violates a permit condition is subject to a civil penalty not
to exceed $10,000 per day of such violation. Any person who willfully or
negligently violates a permit condition is guilty of a misdemeanor punishable
by a fine not to exceed $15,000 per day of violation, or by imprisonment
not to exceed six months or both.
3. Duty to Mitigate
The permittee shall take all reasonable steps to minimize any adverse impact
to navigable waters resulting from noncompliance with any effluent limitations
specified in this permit, including accelerated or additional monitoring as
necessary to determine the nature and impact of the noncomplying discharge.
4. Permit Modification
After notice and opportunity for a hearing pursuant to NCGS 143-215. 1(b)
(2) and NCGS 143-215. 1(e) respectively, this permit may be modified, suspended,
or revoked in whole or in part during its term for cause including, but not
limited to, the following:
a. Violation of any terms or conditions of this permit;
b. Obtaining this permit by misrepresentation or failure to disclose fully
all relevant facts;
c. A change in any condition that requires either a temporary or permanent
reduction or elimination of the authorized discharge; or
d. Information newly acquired by the Division indicating the discharge poses
a threat to human health or welfare.
If the permittee believes that any past or planned activity would be cause for
modification or revocation and reissuance, the permittee must report such
information to the Permit Issuing Authority. The submittal of a new application

•
Part II
Page 2 of 14
may be required of the permittee. The filing of a request by the permittee for
a permit modification, revocation and reissuance, or termination, or a
notification of planned changes or anticipated noncompliances, does not stay
any permit condition.
5. Toxic Pollutants
Notwithstanding Part II, A-4 above, if a toxic effluent standard or prohibition
(including any schedule of compliance specified in such effluent standard or
prohibition) is established under Section 307(a) of the Act for a toxic
pollutant which is present in the discharge, if such standard or prohibition
is more stringent than any limitation for such pollutant in this permit, this
permit shall be revised or modified in accordance with the toxic effluent
standard prohibition and the permittee so notified.
The permittee shall comply with effluent standards or prohibitions established
under Section 307(a) of the Clean Water Act for toxic pollutants within the
time provided in the regulations that establish those standards or prohibitions,
even if the permit has not yet been modified to incorporate the requirement.
6. Civil and Criminal Liability
Except as provided in permit conditions on "Bypassing" (Part II, B-3) and
"Power Failures" (Part II, B-6), nothing in this permit shall be construed
to relieve the permittee from any responsibilities, liabilities, or penalties
for noncompliance pursuant to NCGS 143-215.3, 143-215.6 or Section 309 of the
Federal Act, 33 USC 1319. Furthermore, the permittee is responsible for
consequential damages, such as fish kills, even though the responsibility
for effective compliance may be temporarily suspended.
7. Oil and Hazardous Substance Liability
Nothing in this permit shall be construed to preclude the institution of any
legal action or relieve the permittee from any responsibilities, liabilities,
or penalties to which the permittee is or may be subject to under NCGS
143-215.75 et seq. or Section 311 of the Federal Act, 33 USC 1321 . Furthermore,
the permittee is responsible for consequential damages, such as fish kills,
even though the responsibility for effective compliance may be temporarily
suspended.
8. Property Rights
The issuance of this permit does not convey any property rights in either real
or personal property, or any exclusive privileges, nor does it authorize any
injury to private property or any invasion of personal rights, nor any
infringement of Federal, State or local laws or regulations.

Part II
Page 3 of 14
9. Onshore of Offshore Construction
This permit does not authorize or approve the construction of any onshore or
offshore physical structures or facilities or the undertaking of any work
in any navigable waters.
10. Severability
The provisions of this permit are severable, and if any provision of this
permit, or the application of any provision of this permit to any circumstances,
is held invalid, the application of such provision to other circumstances, and
the remainder of this permit, shall not be affected thereby.
11. Duty to Provide Information
The permittee shall furnish to the Permit Issuing Authority, within a reason-
able time, any information which the Permit Issuing Authority may request
to determine whether cause exists for modifying, revoking and reissuing,
or terminating this permit or to determine compliance with this permit. The
permittee shall also furnish to the Permit Issuing Authority upon request,
copies of records required to be kept by this permit.
SECTION B. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS
1. Proper Operation and Maintenance
The permittee shall at all times maintain in good working order and operate
as efficiently as possible all treatment or control facilities or systems
installed or used by the permittee to achieve compliance with the terms
and conditions of this permit.
2. 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.
3. Bypassing
Any diversion from or bypass of facilities is prohibited, except (i) where
unavoidable to prevent loss of life or severe property damage, or (ii)
where excessive storm drainage or runoff would damage any facilities
necessary for compliance with the effluent limitations and prohibitions of this
permit. All permittees who have such sewer bypasses or overflows of this
discharge shall submit, not later than six months from the date of issuance
of this permit, detailed data or engineering estimates which identify:
a. The location of each sewer system bypass or overflow;
b. The frequency, duration and quantity of flow from each sewer system
bypass or overflow.

•

Part II
Page 4 of 14
This requirement is waived where infiltration/inflow analyses are scheduled
to be performed as part of an Environmental Protection Agency facilities
planning project.
The permittee shall report by telephone to either the central office or
appropriate regional office of the Division as soon as possible, but in
no case more than 24 hours or on the next working day following the
occurrence or first knowledge of the occurrence of any division from or
bypass of facilities.
4. Upsets
"Upset" means an exceptional incident in which there is unintentional and
temporary noncompliance with technology based permit effluent limitations
because of factors beyond the reasonable control of the permittee. An upset
does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities,
lack of preventive maintenance, or careless or improper operation. An upset
constitutes an affirmative defense to an action brought for noncompliance
with such technology based permit limitation if the requirements of 40 CFR S
122.41(n)(3) are met.
5. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of
treatment or control of wastewaters shall be disposed of in accordance with
NCGS 143-215. 1 and in a manner such as to prevent any pollutant from such
materials from entering waters of the State or navigable waters of the United
States.
6. Power Failures
The permittee is responsible for maintaining adequate safeguards to prevent the
discharge of untreated or inadequately treated wastes during electrical power
failures either by means of alternate power sources, standby generators or
retention of inadequately treated effluent.
SECTION C. MONITORING AND RECORDS
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be
characteristic of the volume and nature of the permitted discharge. Samples
collected at a frequency less than daily shall be taken 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
this permit and, unless otherwise specified , before the effluent joins or is
diluted by any other wastestream, body of water, or substance. Monitoring points
shall not be changed without notification to and the approval of the Permit
Issuing Authority.

•
Part II
Page 5 of 14
2. Reporting
Monitoring results obtained during the previous month(s) shall be summarized for
each month and reported on a monthly Discharge Monitoring Report (DMR) Form
(DEM No. MR 1, 1. 1, 2, 3) or alternative forms approved by the Director, DEM,
postmarked no later than the 30th day following the completed reporting period.
The first DMR is due on the last day of the month following the issuance of the
permit or in the case of a new facility, on the last day of the month following
the commencement of discharge. Duplicate signed copies of these, and all other
reports required herein, shall be submitted to the following address:
Division of Environmental Management
Water Quality Section

3 Flow Measurements
Appropriate flow measurement devices and methods consistent with accepted
scientific practices shall be selected and used to insure the accuracy and
reliability of measurements of the volume of monitored discharges. The
devices shall be installed, calibrated and maintained to insure that the
accuracy of the measurements are consistent with the accepted capability of
that type of device. Devices selected shall be capable of measuring flows
with a maximum deviation of less than + 10% from the true discharge rates
throughout the range of expected discharge volumes. Once-through condenser
cooling water flow which is monitored by pump logs, or pump hour meters as
specified in Part I of this permit and based on the manufacturer's pump
curves shall not be subject to this requirement.
4. Test Procedures
Test procedures for the analysis of pollutants shall conform to the EMC
regulations published pursuant to NCGS 143-215.63 et seq, the Water and Air
Quality Reporting Acts, and to regulations published pursuant to Section 304(g),
33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and
Regulation 40 CFR 136.
5. Penalties for Tampering

this permit including all records of analyses performed and calibration and
maintenance of instrumentation and recordings from continuous monitoring
instrumentation shall be retained for a minimum of three (3) years by the
permittee. Thisperiod of retention shall be extended during the course
of any unresolved litigation or if requested by the Division of Environmental
Management or the Regional Administrator of the Environmental Protection Agency.
7. Recording Results

Part II
Page 7 of 14
in new, different, or increased discharges of pollutants must be reported by
submission of a new NPDES application or, if such changes will not violate
the effluent limitations specified in this permit, by notice to the DEM of
such changes. Following such notice, the permit may be modified to specify
and limit any pollutants not previously limited.
2. Anticipated Noncompliance
The permittee shall give notice to the Permit Issuing Authority of any planned
change in the permitted facility or activity which may result in noncompliance
with permit requirements. Any maintenance of facilities, which might
necessitate unavoidable interruption of operation and degradation of effluent
quality, shall be scheduled during noncritical water quality periods and carried
out in a manner approved by the Permit Issuing Authority.
3. Transfer of Ownership or Control
This permit is not transferable. In the event of any change in name, control
or ownership of facilities from which the authorized discharge emanates or is
contemplated, the permittee shall notify the prospective owner or controller by
letter of the existence of this permit and of the need to obtain a permit in the
name of the prospective owner. A copy of the letter shall be forwarded to the
Division of Environmental Management.
4. Additional Monitoring by Permittee
If the permittee monitors any pollutant at the location(s) designated herein
more frequently than required by this permit, using approved analytical methods
as specified above, the results of such monitoring shall be included in the
calculation and reporting of the values is required in the DMR. Such increased
frequency shall also be indicated. The DEM may require more frequent monitoring
or the monitoring of other pollutants not required in this permit by written
notification.
5. Averaging of Measurements
Calculations for limitations which require averaging of measurements shall
utilize an arithmetic mean unless otherwise specified by the Permit Issuing
Authority in the permit.
6. Noncompliance Notification
The permittee shall report by telephone to either the central office or the
appropriate regional office of the Division as soon as possible, but in
no case more than 24 hours or on the next working day following the
occurrence or first knowledge of the occurrence of any of the following:

•
Part II
Page 8 of 14
a. Any occurrence at the water pollution control facility which results in
the discharge of significant amounts of wastes which are abnormal in
quantity or characteristic, such as the dumping of the contents of a
sludge digester; the known passage of a slug of hazardous substance
through the facility; or any other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render
the facility incapable of adequate wastewater treatment such as mechanical
or electrical failures of pumps, aerators, compressors, etc.
c. Any failure of a pumping station, sewer line, or treatment facility
resulting in a by-pass directly to receiving waters without treatment
of all or any portion of the influent to such station or facility.
d. Any time that self-monitoring information indicates that the facility has
gone out of compliance with its NPDES permit limitations.
Persons reporting such occurrences by telephone shall also file a written
report in letter form within 15 days following first knowledge of the
occurrence.
7. Changes in Discharges of Toxic Substances:
The permittee shall notify the Permit Issuing Authority as soon as it knows or
has reason to believe:
a. That any activity has occurred or will occur which would result in the
discharge, on a routine or frequent basis, of any toxic substance(s) (listed
at 40 CFR S 122, Appendix D, Table II and III) which is not limited in the
permit, if that discharge will exceed the highest of the following
"notification levels".
(1) One hundred micrograms per liter (100 ug/l);
(2) Two hundred micrograms per liter (200 ug/l) for acrolein and
acrylonitrile; five hundred micrograms per liter (500 ug/l)
for 2,4-dinitrophenol and for 2-methyl-4,6-dinitrophenol; and one
milligram per liter (1 mg/1) for antimony; or
(3) Five (5) times the maximum concentration value reported for that
pollutant(s) in the permit application.
b. That any activity has occurred or will occur which would result in any
discharge, on a non-routine or infrequent basis, of a toxic pollutant
(listed at 40 CFR S 122, Appendix D. Table II and III) which is not
limited in the permit, if that discharge will exceed the highest of the
following "notification levels":

•
Part II
Page 9 of 14
(1) Five hundred micrograms per liter (500 ug/1);
(2) One milligram per liter (1 mg/1) for antimony; or
(3) Ten (10) times the maximum concentration value reported for that
pollutant(s) in the permit application.

SECTION E. DEFINITION
1. Permit Issuing Authority
The Director of the Division of Environmental Management.
2. DEM or Division
Means the Division of Environmental Management, Department of Natural
Resources and Community Development.

Part II
Page 11 of 14
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 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 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 all daily discharges
samples and/or measured during a calendar month on which daily discharges
are sampled and measured, divided by the number of daily discharges sampled
and/or measured during such month (arithmetic mean of the daily
concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the
arithmetic mean (weighted by flow value) of all the samples collected
during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a
calendar month. This limitation is identified as "Monthly Average" 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.
