A#.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS (cont.)
Footnotes:
1. Sample locations: E - Effluent, I - Influent, U - Upstream at NCSR 1700, D - Downstream at (1) NC Highway 42
and (2) NCSR 1908. Stream samples shall be grab samples and shall be collected 3/ Week during June - September
and 1/Week during the remaining months of the year. Instream monitoring is provisionally waived in light of the
permittee's participation in the Lower Neuse Basin Association. Instream monitoring shall be conducted as stated in
this permit should the penmittee end its participation in the Association. Per 15A NCAC 2B .0505(c)(4), stream
sampling (as well as influent/effluent sampling) may be discontinued when flow conditions could result in injury or
death of the person(s) collecting the samples. In such cases, on each day that sampling is discontinued, written
justification shall be specified in the monitoring report for the month in which the event occurred.
2. The monthly average effluent BOD5 and Total Suspended Solids concentrations shall not exceed 15% of the
respective influent value (85% removal).
3. The daily average dissolved oxygen effluent concentration shall not be less than 6.0 mg/L.
4. Total residual chlorine is required only if chlorine is used as a disinfectant (or elsewhere in the process). The
Division shall consider all effluent total residual chlorine values reported below 50 µg/L to be in compliance with
the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina
certified laboratory (including field certified), even if these values fall below 50 jig/L.
5.. For a given wastewater sample, TN = TKN + NO2-N + NO3-N, where TN is Total Nitrogen, TKN is Total Kjeldahl
Nitrogen and NO2-N and NO3-N are Nitrate and Nitrite Nitrogen, respectively.
6. TN Load is the mass load of TN discharged by the Permittee in a period of time. See Special Condition A. (2.),
Calculation of TN Loads.
7. Compliance with these limits shall be determined in accordance with Special Condition A. (3.), Annual Limits for
Total Nitrogen.
8. The quarterly average for total phosphorus shall be the average of composite samples collected weekly during the
calendar quarter aanuary-March, April -June, July -September, October -December).
9. Mercury shall be monitored using a grab sample and analyzed using EPA Method 1631.
10. Chronic Toxicity (Ceriodaphnia dubia) P/F at 2.0 %: March, June, September, and December [see Special Condition
A.(5)].
11. The permittee shall perform three Effluent Pollutant Scans during the term of this permit [see A. (6)].
12. No later than 270 days from the effective date of this permit, begin submitting discharge monitoring reports
electronically using NC DWR's eDMR application system. See Special Condition A (8).
b. There shall be no discharge of floating solids or visible foam in other than trace amounts.
A.(2.) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
Monthly TN Load (lb/mo) = TN x TMF x 8.34
where:
TN = the average Total Nitrogen concentration (mg/ L) of the
composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month (MG/ mo)
8.34 = conversion factor, from (mg/L x MG) to pounds
ii. Annual TN Load (lb/yr) = Sum of the 12 Monthly TN Loads for the calendar year
b. The Permittee shall report monthly Total Nitrogen results (mg/L and lb/mo) in the discharge
monitoring report for that month and shall report each year's annual results (lb/yr) in the
December report for that year.
Page 4 of 11
Permit NC0025453
A.(3.) ANNUAL LIMITS FOR TOTAL NITROGEN
a. Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River
basin apply on a calendar year basis.
b. For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in
this Permit if:
i. the Permittee's annual TN discharge is less than or equal to its TN Load limit, or
ii. the Permittee is a co-permittee member of a compliance association.
C. If the Permittee is not a co-permittee member of a compliance association and the Permittee's
cumulative annual TN discharge exceeds the effective TN Load limit in this permit at any point
during the calendar year, the Permittee is in violation of its TN Load limit, and each day of a
continuing violation shall constitute a separate violation.
d. The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the
Permittee's TN allocation.
Allowable changes include those resulting from purchase of TN allocation from the
Wetlands Restoration Fund; purchase, sale, trade, or lease of allocation between the
Permittee and other dischargers; regionalization; and other transactions approved by the
Division.
ii. The Permittee may request a modification of the TN Load limit in this Permit to reflect
allowable changes in its TN allocation. Upon receipt of timely and proper application, the
Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
iii. Changes in TN limits become effective on January 1 of the year following permit
modification. The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
iv. Application shall be sent to:
NCDWR / NPDES Programs
Attn: Neuse River Basin Coordinator
1617 Mail Service Center

discharge during that year is governed by that association's group NPDES permit and the TN
limits therein.
i. The Permittee shall be considered a Co-Permittee Member for any given calendar year in
which it is identified as such in Appendix A of the association's group NPDES permit.
ii. Association roster(s) and members' TN allocations will be updated annually and in
accordance with state and federal program requirements.
iii. If the Permittee intends to join or leave a compliance association, the Division must be
notified of the proposed action in accordance with the procedures defined in the association's
NPDES permit.
(A) Upon receipt of timely and proper notification, the Division will modify the permit as
appropriate and in accordance with state and federal program requirements.
(B) Membership changes in a compliance association become effective on January 1 of the
year following modification of the association's permit.
f. The TN monitoring and reporting requirements in this Permit remain in effect until expiration of
this Permit and are not affected by the Permittee's membership in a compliance association.

modifications under state and federal rules.
A.(5.) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 2.0 %.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or
subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised- December 2010) or subsequent versions. The tests will be performed during the months of
March, June, September, and December. These months signify the first month of each three month
toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained
during representative effluent discharge and 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
Page 6 of 11
Permit NC0025453
following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -December 2010) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent
Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter
code TGP3B for the pass/fail results and THP313 for the Chronic Value. Additionally, DWR Form AT-3
(original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the
report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to
the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month. Assessment of toxicity compliance is based on
the toxicity testing quarter, which is the three month time interval that begins on the first day of the
month in which toxicity testing is required by this permit and continues until the final day of the third
month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
If the Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT
Form submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.

Beginning no later than 270 days from the effective date of this permit, the permittee shall begin
reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located ui an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements may
be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,1.1, 2, 3)
or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above.
Page 9 of 11
Permit NCO025453
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdenr.org/web/wq/admin/bo /ipu/edmr
Regardless of the submission method, 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.
b. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) �d)l
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II,
Section B. (11.) (a) or by a duly authorized representative of that person as described in Part H,
Section B. (11)(b). A person, and not a position, must be delegated signatory authority for eDMR
reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user
account and login credentials to access the eDMR system. For more information on North Carolina's
eDMR system, registering for eDMR and obtaining an eDMR user account, please visit the following

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. These samples shall be
representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative of
the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), 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 Week
The period from Sunday through the following Saturday.
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
Version 1110912011
NPDES Permit Standard Conditions
Page 2 of 18
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a
constant time interval. Use of this method requires prior approval by the Director. This method may only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples 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. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
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. 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).

Facility Closure
Cessation of all activities that require coverage under this NPDES permit. 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).

Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.
Monthly Average (concentration limit)

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011
NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
1. Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
2. Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
3. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40

wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
(3) Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause Interference with the POTW;
(5) Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the

SUMMARY
The Town of Clayton operates a 2.5 MGD wastewater treatment facility, known as the Little
Creek Water Reclamation Facility (Little Creek WRF). The facility treats to reuse standards and
delivers reclaimed water to the Pine Hollow Golf Course under permit W00022224. The
treatment system consists of mechanical and manual bar screens, influent pumping station,
grit removal, anaerobic selector, two anoxic tanks, two oxidation ditches, three clarifiers, two
tertiary filters, UV disinfection, two drum sludge thickeners, two sludge holding tanks and one.
aerobic digester.
2
The permittee submitted a permit renewal application on September 27, 20 V. The application
was deemed complete. The current permit expired March 31, 2013.
The Town has a full pre-treatment program with 1 non -categorical SIU and 3 CIUs. This
program will continue to be implemented in accordance with the permit.
RECEIVING STREAM
This facility discharges to Neuse River in the Neuse River Basin, classified WS-IV NSW CA
waters, HUC 0320201. This section of the Neuse River is not listed on the 2012 NC 303(d) list.
Nitrogen
The Environmental Management Commission adopted Nutrient Management Strategy rules in
December 1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The
point source rule (T15A NCAC 2B .0234) sets Total Nitrogen (TN) discharge limits for all point
source dischargers larger than 0.5 MGD.
Page 1
The rule also allows dischargers to form a group compliance association and work together to
reduce nitrogen; this option allows the association members added flexibility in controlling
nitrogen discharges. At the same time, the association is subject to a group NPDES permit
ensuring that the association and its individual members are accountable if they exceed the
applicable nitrogen limits.
Under the rule, there are three types of TN limit in the Neuse:
1. the individual limits in the dischargers' individual permits,
2. the aggregate limit in an association's group NPDES permit, and
3. the individual allocations/limits for each Association member, also in that association
permit.
A discharger may be subject to the first type of limit, or to the second and third, but never to
all three at the same time. The discharger is first subject to the TN limit (if any) in its individual
NPDES permit. If becomes a co-permittee to a compliance association's group NPDES permit, it
is then governed by the TN limits in that permit. If the association complies with its group TN
limit in a given year, all members are deemed to be in compliance with their individual
allocations/ limits in the group permit. If the association exceeds its limit, the members then
become subject to their individual allocations/ limits as well.
Regardless of which permit governs a TN discharge, allocations/ limits will likely change over
time as the dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations.
The Division will modify the affected permits as necessary to ensure that the limits are kept up
to date and reflect any such transactions.
The Permittee is a member of the Neuse River Compliance Association at this time. So long as
it remains a co-permittee member, it is deemed to be in compliance with the TN limit in this
permit, and its TN discharge is governed instead by the Association's group NPDES permit,
issued December 30, 2002.

The Town' active allocation is 11,416 lb/year at thedieekcgs equivalent to 22,832 lb/yr at
the The allocation includes the county's original allocation assigned by rules in
addition to supplemental allocations obtained through purchases. The Town has 9,194 lb/yr in
reserve allocation.

Phosphorus
The City's 2.0 mg/L Total Phosphorus limit is carried forward in the new permit. However, it is
now a quarterly average limit rather than a weekly average, to conform with the new rule.
DMR data:
DMR data was reviewed for the period of January 2010 to November 2013. The permittee was
in compliance with the permit limits for the period reviewed except for one pH lower limit
violation. All analysis for the following metals were below laboratory detection levels: arsenic,
cadmium, chromium, lead, molybdenum, selenium, cyanide, thallium, and arsenic.

Reasonable Potential Analysis:
A reasonable potential analysis was performed for copper, nickel, and zinc. Results show these
parameters have no reasonable potential to exceed the water quality standards. See attached
RPA table for results and monitoring changes recommendations.
Instream Monitoring: evsThe Town of Clayton is a member of the Lower Neuse Basin Association. Theamples
two stations in the area, one upstream and one downstram of the discharge. Data shows that
water quality parameters are similar upstream and downstream of the discharge and are
within the water quality standards.
Priority Pollutant Analysis (PPA(:
The application includes the results of three priority pollutant analyses. No pollutants were
detected in the scan.
Mercury Evaluation:
A mercury evaluation was conducted in accordance with the Permitting Guidance developed for
the implementation of the 2012 Statewide Mercury TMDL to determine the need for a limit and
a Mercury Minimization Plan (MMP). Based on dilution at the point of discharge the water
quality based effluent limitation (WQBEL) is 588 ng/l. All samples for mercury were less than
detection. The method used was Method 245.1 which gives a detection level of 0.2 ug/l. The
technology base effluent limitation (TBEL) of 47 ng/1 is below the detection level of the method
used. The permit will require quarterly mercury monitoring using method 1631E to obtain data
to evaluate the need for a limit. A Mercury Minimization Plan will be required as the discharge
is greater than 2 MGD.
Aquatic Toxicity Testing
Permit requires chronic toxicity, ceriodaphnia dubia,.2.0 %. The facility consistently passed the
toxicity tests.

Little Creek Water Reclamation
Town of Clayton, NC
NPDES Permit # NCO025453
Introduction:
The Town of Clayton owns and operates a municipal wastewater collection and treatment
OWA
system, reclaim water, pretreatment program, operates a certified laboratory and
maintains a land application program. Wastewater processed by the treatment facility
originates from domestic and industrial sources. The approximate ratios of these sources
are seventy percent domestic and thirty percent industrial. The Town also has inter local
�►►
agreements with Johnston County Utilities and the City of Raleigh to treat wastewater
from the area. This sludge management plan, as required by the NC Division of Water
Quality, outlines plant processes and management procedures to ensure biosolids disposal
meets both state and federal requirements.
Process Description
Aft,
00 , The Town of Clayton owns and operates a 2.5 mgd water reclamation facility. The
,,� facility is named; Little Creek Water Reclamation Facility and operates under NPDES
Permit # NC0025453. The facility also delivers reclaim water to the Pine Hollow Golf
''� under Permit # WQ0022224. The facility is also covered under Stormwater Permit
� #NCG 110000.
The plant consists of a mechanical and manual bar screen, Jeta (Vortex) type grit removal
OWN
system, 9 inch parshall flume with flow meter, and a composite sampler. The influent
pumping station has three 60 hp dry pit submersible pumps and one 40 hp pump.
Biological nutrient removal is achieved by Carrousel Denite R System (Eimco), the
system contains an anaerobic selector, two anoxic tanks, and two oxidation ditches. The
biological system is controlled by a PLC based control system that monitors oxygen
throughout the system. The plant also has three circular clarifiers, two mixed bed tertiary
�►
filters, ultraviolet disinfection, effluent pumping station, in plant reuse pumping system,
and a reclaim water pumping station. In addition to the biological systems, the plant has
chemical feed for alkalinity (magnesium hydroxide), alum precipitation (alum sulfate),
and flocculation (polymer).
The sludge conditioning and disposal systems consist of: two drum thickeners (80 gpm &
300 gpm), polymer flocculation, two .36 mg aerated holding tanks, one .09 mg aerobic
digester, and sludge transfer pump.

MON
Sludge Disposal Options:
The Town maintains a Residuals Land Application Permit # WQ 0023178. The permit
allows up to 400 dry tons per year of Class B on local farm land. Additional capacity is
available through the use of dewatered solids disposal and off site dewatering.
The Town is also included permitted at the Johnston County Landfill for dewatered solids
and also maintains an agreement with Johnston County Utilities to dewater thickened
biosolids at the landfill site. The Town may also use McGill Environmental for
composting at its Roseboro or New Hill composting site.
Responsible Persons:
The land application operator in responsible charge is responsible for ensuring that the
sampling and maintenance functions are carried out as outlined in the land application
permit.
Sampling Plan:
The following sampling protocols shall be followed. All samples will be collected in
clean and/or sterilized containers provided by the contract laboratory. Chain of custody
information is required for each sample collected (see attachment one). Sampling
equipment shall be cleaned prior to and after sample collection. Sampling equipment
used to collect fecal coliforms shall be sterilized prior to sample collection; all others will
be cleaned with laboratory grade detergent and rinsed with deionized water.
Sample Requirements:
Quarterly Samples:
Location: Sludge Holding Tanks
Aluminum, Ammonia -Nitrogen, Arsenic, Cadmium, Calcium, Copper, Lead,
Magnesium, Mercury, Molybdenum, Nickel, Nitrate -Nitrite Nitrogen, Phosphorus,
Potassium, pH, Plant Available Nitrogen (by calculation), Selenium, Sodium, Silver, %

rA% Fecal coliforms will be collected from the sludge holding tank form the walkway using a
?010, sterilized stainless steel dipper. This walkway is the only safe means to sample this tank.
The seven samples will be collected prior to disposal. Plant staff should request a five-
AMOS day turn -around on all samples collected and be aware of the short holding times of 6
Onb► hours. In order to meet Class B requirements, the geometric mean must be less than 2
,�,■e, million (MPN/gram TS, or CFU/gram TS). If the counts exceed the regulatory limits the
biosolids may not be land applied until the limits are met.
Nutrient, metals, and TCLP analysis contained in the land application and composting
permits will be collected from the sludge holding tank via a clean dipper using a four
sample composite method. The aliquots shall be collected from the walkway at two hour
intervals. The aliquots should be — 800 milliliters and placed in a gallon jug in the
laboratory refrigerator. After the fourth sample is added the sample should be well mixed
and transferred into the proper sample containers. A chart is provided on specific sample
requirements. Temperature and pH are grab samples and the pH shall be temperature
corrected.
Plant personnel will document and use the following chart for the temperature correction
for all pH readings.

holding tank. Prior to land application a contractor will be used to supply calcium
carbonate at a level to achieve a ph of > 12 units for two hours and maintain a pH of >
11.5 for an additional 22 hours. There will be no additional material added to the tank
until the land application is complete. A log sheet will be maintained on -site and will
contain the following information: date, times, location, purpose, amount of material
added, initial pH, pH after addition, pH two hours after addition, pH twenty two hours
after addition, names of persons involved, completion date and volume of biosolids land
applied. If the required parameters are not met the process must be successfully
completed prior to land applying the sludge. Note: It is a good practice to perform ajar
test to the contents of the tank prior to treatment, in order to determine the required
amount of alkali to add.
Alternatively a specific oxygen uptake may be performed if the solids concentration is
less than two percent and enough digestion time has been provided, a spreadsheet
provided by the land application unit shall be used for the calculations, a minimum of
seven samples must be taken.
Pathogen reduction:
Pathogen reduction shall be qualified by Fecal Coliform testing from the holding tanks. A
minimum of seven samples will be collected per quarter based upon permit requirements.
Sampling is not required when no events occur during the quarter.
Spill control and prevention:
The facility has a spill control plan as required by the facility's storm water permit. The
sludge loading area has a contoured drainage area that empties into an in plant recycle
system.
The Town's hauling contractor is required to have a spill control/ prevention plan.
Inspections:
The land application ORC is required to ensure that the permit conditions are being met
by plant personnel and the sludge application contractor. During each application event
the ORC or backup ORC will visit the sites in use.
Land application rates are based upon Realistic Yield Expectations based upon
information acquired from the North Carolina Department of Agriculture and Consumer
Services. The rates are used by the Town's contracted soil scientist who prepares
quarterly application summaries and the annual report.
Should the sodium adsorption rate (SAR) of ten (10) or higher be encountered, the Town
will utilize the services of a registered soil scientist to make recommendations to
maintain soil quality.
This is a working document; it must be reviewed periodically for completeness and
efficiency and does not replace the requirements in the various government standards and
permits.
