On January 1, 2001, a final permit for the .subject facility became effective. On Januay 9, 2001, the
Division of Water Quality (Division) received a letter from your office requesting some clarifications to the
effluent limits page as well as the correction of some typographical errors which identified the subject facility
as the Spencer WWTP instead of the Sowers Ferry Road WWTP. The errors, which occ-urredon the
supplement to the permit cover page and the facility map, have been corrected- In addition, changes have been made to the effluent limits page in order to clarify instrearn monitoring requirements and nutrient limits.
Please find enclosed the revised permit pages. The revised pages should be inserted into your permit.
The old pages may then be discarded. All other terms and conditions contained in the original permit remain
unchanged and in full effect. This permit modification is issued under the requirements of North, Carolina
General Statutes 143.-215.1 and the Memorandum of Agreement between North Carolina and the U. S.
Environmental Protection Agency.
If any parts, measurementfrequencies or sampling requirements contained in this permit
modification 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 a written petition conforming to
Chapter 150B of the North Carolina General Statutes, filed with the Office of Administrative Hearings (6714

Subject: Issuance of NPDES Permit NC0025593
Sowers Ferry Road WWTP
Rowan County
Dear Mr. Vest:
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 am.ended).
After a review of the draft permit, the following changes have been made to the final permit;
• In recognitio.nof the recent acquisition of the Sowers Ferry Road WWTP by the City of Salisbury from the
Town of Spencer, the appropriate name and ownership information. has been changed.
• A compliance schedule has been included so that you may have adequate time to meet. the Total
Phosphorus and Total Nitrogen nutrient limits., , It is the Division's understanding that work is underway to
connect the Spencer collection system to the Salisbury WWTP. A construction schedule submitted by
Peirson and Whitman Architects and Engineers. indicates that the completion date for the construction is
March 2002. The Sowers Ferry Road facility will be exempt from nutrient limits until September 2002, by
which time it is expected that the construction will be finished and the discharge terminated,
• The months during, which your facility must perform Chronic Toxicity testing have been changed to those
during which samples are currently taken: January, April, July and October.
It has been noted that the Sowers Ferry Road WWTP is a Class facility, however, the monitoring frequencies
contained in the draft permit were applicable to a Class IV facility. Unfortunately, we cannot grant your request to omit
conductivity from the permit. It is Division policy that any municipality treating waste froman industrial source be
given conductivity monitoring.
If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to
vou, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this
e.ter, 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 Natalie Sierra at telephone number [phone],

A.(3.) — CHRONIC TOXICITY MONITORING/LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Cenadaphnia dubia at an effluent concentration of 17%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined
in the "North Carolina Ceriodap;mia Chronic Effluent Bioassay Procedure," Revised February 1998,
or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised -February 1998) or subsequent versions. The tests will be performed during the months of
January, April, July and October. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed, at a minimum,
in each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are

STANDARD CONDITIONS FOR NPDES PERMITS
SECTION A. DEFINITIONS
➢ . Permit Issuing Authority
The Director of the Division of Water Quality.
DEM or "the Division"
Means the Division of Water Quality, Department of Environment, 1 iealth and Natural Resources.
EMC
Used herein means the North Carolina Environmental Management Commission.
4. Act gr "the Act"
The Federal Water Pollution Control Act, also kno srn as the Clean Water Act, as amended, 33 USC

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 1 of the permit.
o:. 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.
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 surn 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.
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. Row 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 'I /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 ot 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 sumrnation of each concentration
times its respective flow divided by the summation of the respective flows.

(A) Bypass was unavoidable to prevent loss of life, personal injury or severe pro
damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes or maintenance during normal periods of
equipment downtime. This condition is not satisfied if adequate backup equipment should
have been installed in the exercise of reasonable engineering judgment to prevent a bypass
which occurred during normal periods of equipment downtime or preventive maintenance;
and
(C) The permittee submitted notices as required under Paragraph c. of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its
adverse affects, if the Permit Issuing Authority determines that it will meet the three
conditions listed above in Paragraph d. (1) of this section.

Part II
Page 9 of 14
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.

Wasteload Allocation Summary
(approach taken, correspondence with region, EPA, etc.)
Discharge is to low velocity area of Grants Creek - essentially a small take_ Extreme water quality impacts -
color, DO, eutrophication, toxicsk.,„The existing limits for Salisbury and Spencer do not protect water quality.
However, most limits will be renewed until the Yadkin River Plan is promulgated: Since this will be a five year
permit, nutrient limits should be included at this time. Localized nutrient impairment in Grants Creek is well
documented. Algal blooms and chlorophyll -a violations regularly occur. Instream levels of nutrients exceed
DEM's targets for prevention of algal blooms. Per our SOP, limits of TP - 03 mg/1 and TN = 3.0 mgel are
recommended due to the instrearn waste concentration. However, technologylimits of TP m
�' g/1)=C3.5(l.tJ)and.7
TN (mgfl) = 4.0 (8.0) for summer (winter) will be required. An implementation schedule should be developed for
compliances with these limits or removal of the discharge through connection to the Salisbury WWTP.

CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in:
1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay
Procedure Revised *September 1989) or subsequent versions.
The effluent concentration al which there may be no observable inhibition of reproduction or significant mortality
is % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform
cog:ldy monitoring using this procedure to establish compliance with the permit condition. The first test will be
performed r thirty days from the effective date of this pcanit during tIse months of
J tel-N J u T . Effluent sampling for this testing shall be performed at the NPDES
permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition wW be entered on the Effluent Discharge
Monitoring Farm (MR-1) for the month in which it was performed, using the parameter code TGP3B,
Additionally, DEM Form AT-1 (original) is to be sent to the following address:
Attention: Environmental Sciences Branch
North Carolina Division of
Environmental Management
4401 Reedy Creek Road
Raleigh, N.C. 27607
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in
association with the toxicity tests, as well 'as all dosetresponse data. Total residual chlorine of the effluent toxicity
sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should any single quarterly monitoring indicate a failure to meet specified limitsthen monthly monitoring will
begin immediately until such time that a single test is passed. Upon passing, this monthly test requirement will
revert to quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Environmental Management indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute
noncompliance with monitoring requirements.
