Subject: Issuance of NPDES Permit
Permit No. NC0O25861
City of Lowell WWTP
Gaston County
Dear Mr. Blackburn:
In accordance with the application for discharge permit received, the Division is forwarding
herewith the subject NPDES permit. This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina
and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
This final permit authorizes the City of Lowell to discharge domestic wastewater from
the Lowell Wastewater Treatment Plant (WWTP) to an unnamed tributary designated as an
effluent channel to the South Fork of the Catawba River, a class WS-V water in the Catawba
River Basin. This permit includes discharge limitations/or monitoring for flow, BOD5, total
suspended solids, ammonia nitrogen, fecal coliform, total residual chlorine, pH, Total
Nitrogen, Total Phosphorus and Chronic Toxicity.
The following procedure has been recently implemented by DWQ: Total residual
chlorine (TRC) compliance level changed to 50 ug/I. Effective March 1, 2008, the Division
received EPA approval to allow a 50 ug/I TRC compliance level. This change is due to
analytical difficulties with TRC measurements. Facilities will still be required to report actual
results on their monthly discharge monitoring report (DMR) submittals, but for compliance
purposes, all TRC values below 50 ugh' will be treated as zero. A footnote regarding this
change has been added to the effluent limitations pages in the permit.

2. The Division shall consider all effluent TRC values reported below 50 ug/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 ug/L.
3. Chronic Toxicity(Ceriodaphnia)at 0.74%: February, May,August& November(See A. (2.)).
There shall be no discharge of floating solids or visible foam in other than trace amounts.

Permit NC0025861
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) - 0.6 MGD
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 0.74%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the"North
Carolina Ceriodaphnia 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 February, May,August and
November. 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 specified in the"North Carolina Phase II Chronic
Whole Effluent Toxicity Test Procedure"(Revised-February 1998)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 THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Quality
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.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality 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, 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.

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

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

Subject: NPDES Permit No. NC0025861
City of Lowell WWTP
Gaston County,NC
Dear Mr. Blackburn:
Our records indicate that NPDES Permit No. NC0025861 was issued on January 7, 2005 for
the discharge of wastewater to the surface waters of the State from your facility. The purpose of this
letter is to advise you of the importance of the Permit and the liabilities in the event of failure to
comply with the terms and conditions of the Permit. If you have not already done so, it is suggested
that you thoroughly read the Permit. Of particular importance is Page 4.
Page 4 sets forth the effluent limitations and monitoring requirements for your discharge.
Your discharge must not exceed any of the limitations set forth. The section headed "Monitoring
Requirements" describes the measurement frequencies, sample types and sampling locations. Upon
commencement of your discharge (or operation), you must initiate the required monitoring. The
monitoring results must be entered on reporting forms furnished or approved by this Agency. If you
have not received these forms, they should be arriving shortly. If you fail to receive the forms,please
contact this Office as quickly as possible. I have enclosed a sample of the "Effluent" reporting form
(DWQ Form MR-1), plus instructions for completing the form. It is imperative that all applicable
parts be completed, and the original and one copy be submitted as required.
Please be advised that an annual administering and compliance monitoring fee may be
required for your facility. You will soon be receiving a statement from our Raleigh Office. It is
imperative that the fee be paid in a timely manner so as to prevent enforcement action or possible
revocation of your permit.

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

Permit NC0025861
A. (2.) CHRONIC TOXICITY PERMIT LIMIT - Quarterly
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Cenalaphnia
dubia at an effluent concentration of 0.74%.
The permit holder shall perform at a minimum,quarterly monitoring using test procedures outlined in the"North Carolina
Cericdaphnia 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 February,May,August and November. 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 specified in the"North Carolina Phase II Chronic Whole Effluent
Toxicity Test Procedure" (Revised-February 1998) 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 THP3B for the Chronic Value. Additionally,DWQ Form AT-3 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh,North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch 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(Al) 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 Branch 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.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water
Quality 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,
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.

NPDES Permit Requirements
Page l of 16
PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or"the Act"
The Federal Water Pollution Control Act,also known as the Clean Water Act,as amended,33 USC 1251,et. seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform,the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,which
is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case-by-case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous:a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection,or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system,or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.
Version 6/20/2003

NPDES Permit Requirements
Page 2 of 16
In accordance with (4) above,influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass,the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during that period. (40 CFR 122.3)
Daily Maximum
The highest"daily discharge"during the calendar month.
Daily Sampling

Summary
The subject facility is a municipal WWII'discharging 100% domestic waste. The facility was last permitted in 2002.
The Mooresville Regional Office submitted a staff report on September 13,2004 recommending renewal of this
permit.
Since the last renewal,there have been several enforcement actions against the permittee. The monthly limit for Total
Suspended Solids has been exceeded four times and the weekly average limit for TSS has been exceeded 12 times;also
the fecal coliform weekly average has been exceeded 5 times. Penalties totaling$9,375.00 were assessed for these
violations. All of these violations occurred between January 2002 and July 2003. There have been no violations since
August 2003.
Per Division Policy,a TRC limit (Daily Max)will be added as the facility uses chlorine for disinfection. No
compliance schedule will be given since the facility already uses dechlorination.
The South Fork Catawba River does not appear on the latest 303(d) list.
Copies of the draft permit will be forwarded to the Aquatic Toxicology Unit and the DEH Regional Engineer in the
Mooresville Regional Office for review.

3. This permit does not relieve the permittee from responsibility for compliance with any
other applicable federal, state, or local law, rule, standard, ordinance, order,judgment, or
decree.
4. This permit covers activities associated with the discharge of stormwater from the MS4
within the jurisdictional area of the permittee as described in the approved local
Stormwater Plan to control potential pollution from the MS4. The permit applies to
current and future jurisdictional areas of the permittee, as well as areas that seek coverage
under this permit through inter-local or other similar agreements with the permittee.
Agreements for coverage under this permit must be approved by the Division of Water
Quality, herein referred to as the Division.
5. The Division may deny or revoke coverage under this permit for separate entities and may
require independent permit coverage as deemed necessary. In addition, the permittee may
petition the Division to revoke or deny coverage under this permit for specific entities.

to, any pipe, ditch, channel, tunnel, conduit, well, or discrete fissure from which
stormwater is or may be discharged to waters of the state.
20. Redevelopment
Means any rebuilding activity unless that rebuilding activity;
1. Results in no net increase in built-upon area, and
2. Provides equal or greater stormwater control than the previous development.
21. Stormwater Runoff
The flow of water which results from precipitation and which occurs immediately
following rainfall or as a result of snowmelt.
22. Total Maximum Daily Load (TMDL)
A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can
receive and still meet water quality standards, and an allocation of that amount to the
pollutant's sources. A TMDL is a detailed water quality assessment that provides the
scientific foundation for an implementation plan.The implementation plan outlines the
steps necessary to reduce pollutant loads in a certain body of water to restore and
maintain water quality standards in all seasons. The Clean Water Act, Section 303,
establishes the water quality standards and TMDL programs.
23. Toxic Pollutant
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.

Sludge Management Plan 2004-2005
In an effort to develop a comprehensive approach to Sludge Management the City
of Lowell determined to assess the sludge handling capabilities of their treatment plant
located at 98 Saxony Drive Lowell, North Carolina. The purpose of the plan is two fold,
1)the plan will be a budget tool with which the staff can forecast the cost of disposal and
2) the plan will help demonstrate the current sludge yield characteristic which will help
establish the mass balance of the plant.

•
1.0 DISCRIPTION OF PROCESS
The City of Lowell owns and operates an activated sludge plant located at 98
Saxony Drive in Lowell, North Carolina, N.P.D.E.S. permit number NC0025861. The
Plant as constructed has been in service since April 3, 1968. The original design mode of
operation was Contact Stabilization. The Plant was upgraded in 1995. At that time the
two original drying beds were replaced by four drying beds. The plant continues to serve
the residential and growing commercial population of Lowell. The plant consists of the
following components. (Appendix 1)
• Influent Pump Station, (3)pumps
• Mechanical Bar Screen
• Re-aeration Basins
• Contact Aeration Basin
• Final Clarifier
• Chlorine Gas Disinfection
• Sulfur dioxide de-chlorination system
• Aerobic Digester
• Sludge drying beds(4) @ 30' by 50' by 2' upgraded 1995
• Flow measuring device.
The original design allowed for high flows of textile and domestic waste at a capacity of
600,000 gals. per day. The mode of operation at those flows would be contact
stabilization. The re-aeration tank was designed to retain solids a periodic high flows
without washout. The flow scheme is serial. The current permit limits are 30 mg/I BOD
and 30 mg/I TSS. The plant has no Ammonia limit. The plant discharges into the South
Fork River at an average flow of less than 300,000 gals. /day. The current 16 month
average discharge of BOD is 12.25 mg/1. The current 16 month average for TSS is 25.45
mg/l. The plant is subject to high Inflow and Infiltration as recorded in April 2003. High
flow of 1.85 million gallons on April 10th resulted in solids washout of 566 mg/1 TSS.
2.0 CALCULATED SLUDGE YIELDS
Sludge yields from an activated sludge plant are hard to calculate without
supporting data including influent loading for BOD and TSS lbs. The loading for this
report period (16 months) is assumed to be typical with BOD loaded at .17
lbs./person/day and TSS at 180 mg/l.
Given: Population of 2,661 * .17 lbs,BOD/person/day=452.37 lbs.BOD/day
Given: TSS ® 180mg/1 * .30 * 8,34= 450.361bs.TSS/day
Gross Total lbs./day = 902.73 lbs./day
After treatment, including Aerobic digestion * 65%or.65=
902.73 * .65 = 586.77 net lbs./day
Adjusted for lbs. lost in effluent discharge
@(25.25mg/1TSS+12.25BOD)*.3*8.34=
586.77 lbs/day—93.82 lbs./day= 492.94 adjusted lbs./day
( Annual Yield=492.94 * 365 = 179,9241bs./year or
90 tons/year

CL 1 a1/4'U -)6119
3.0 COST OF DISPOSAL
Currently the City of Lowell uses two disposal options. Air dried sludge from the
drying beds is hauled to the BFI/CMS landfill in Mecklenburg County, North Carolina.
The cost per ton is $40.00. Additional fees include $250.00 each dumpster full (5
per/year) for the required non-hazardous waste manifest, (appendix 2). If all the sludge
could be air dried the annual cost for disposal would be 90 * $40.00 = $3,600.00. This
cost does not include labor to remove sludge from drying beds or transportation to
disposal or manifest fees. The second option for disposal is hauling liquid sludge via
tanker to McAlpine Creek Wastewater Treatment Plant in Charlotte, North Carolina. The
cost per gallon is $0.07 such that 6,000 gals. * $0.07 = $420.00 per load. If the hauled
liquid sludge is concentrated to 2% solids, (20,000mg/l) then each load would be
equivalent to 1000 dry/lbs. for a cost of$840.00 per/ton. The liquid haul option is used
only when the drying beds are full and inclement weather prevents removal of air dried
sludge. (See fig.3.1) The ideal practice for sludge management would be to remove 6,000
gallons of liquid per week @ 2% solids. The benefit is that the high BOD and NH3 in the
filtrate returned from the drying beds would be eliminated.

4.0 LIMITS TO CURRENT OPTIONS
As noted in fig.3.1 a lot of sand is removed when shoveling the sludge from the
beds. Also, the sludge is not 100% dry as the calculation would require. Sludge is
routinely removed from the drying beds at < 25% dry which requires a calculation factor
of at least 4x. Added to this must be the weight of the sand at 15 to 20 % Under humid
conditions drying times can exceed 8 weeks. The percolation capacity of the sand beds is
a function of graded sieve size and blinded surface conditions. (fig.4.2)

(fig.4.2) Drying Bed Number 1.
Each drying bed has a fill capacity of 22,440 gals. (30'*50'*2')7.48gals/ft3. If the
concentration of solids is 2%,(20,000mg/l)then each bed can hold 3,743 lbs. or 1.87 tons.
3,7431bs/492.94 lbs./day = 7.593 days net yield. 7.593 * 4 = 30.37 days capacity. Were
condition require 8 weeks drying time there are only 6.5 cycles/year. 6.5 times 30.37 =
197.42 days maximum production at 100% dry content. Total annual production would
not exceed 48.65 dry/tons,[(48.65*$40.00)]*4=$7,784.00**. That leaves 41.34 tons to be
hauled as 2% liquid. At a cost of $34,725.60 = (41.34*$840.00) Cost combined
$7,784.00 + $1,250.00 + 34,725.00 + labor/transportation could exceed $1,000.00
per/week. (Appendix 3, liquid waste manifest)
** No Labor cost added for manual removal. No Cost added for transportation to landfill.
$1250.00 added for non-hazardous waste manifest, required.

The key to efficient operation of the Wastewater Plant will be solids management.
The N.P.D.E.S. permit requires a minimum removal efficiency of 85% for BOD and
TSS. The current calculated removal efficiency for a 16 month average for TSS is 86%.
The calculated removal for BOD is 93%. These numbers are compliant but leave no room
for error. Solids management in the aerobic digester will require additional attention.

(fig.5.1) Aerobic Digester
The minimum hydraulic detention time, at 20 degrees Celsius is 10-15 days.
Additional days are required if temperature is < 20 degrees. Oxygen requirements are
1.6-1.9 lbs. /per lbs. VSS destroyed. Residual dissolved 02 must be maintained. Diffused
air in the digester not only supplies 02 but also affords good mixing. Solids should be
routinely monitored for MLVSS and decanted to optimum concentration > 2%. The 503
Sludge Regulations require a 38% volatile reduction in order to meet the PSRP criteria.

Well digested sludge should de-water quickly on the drying beds. Thicker decanted liquid
sludge (hauled) will help reduce unit cost per ton. At 3% the cost would be $630.50
per/dry ton.
6.0 SUMMARY
Sludge handling cost for the City of Lowell, North Carolina will exceed
$1,000.00 per week. Improved management methods could result in some savings. The
most difficult variable is weather. Rainey weather prevents sludge from drying on the
drying beds and tends to washout solids from the treatment plant. Solids washout will
result in violations of the N.P.D.E.S. permit limit of 30mg/1 TSS. Permit violations will
result in fines, $250.00 for weekly average violations >45 mg/I and $1,000.00 for
monthly per monthly violation >30 mg/l. TSS violations usually are accompanied by
fecal coliform violation because of higher Chlorine demand. Compliance with the new
N.P.D.E.S. permit limits may be difficult to achieve without some capital improvements
at the plant.
7.0 RECOMMENDATIONS
Sludge dried on the drying beds has the potential of netting reduced cost;
1. Some thought should be given to covering the drying beds with a shelter
in order prevent re-wetting during rain events. An additional benefit will
be reduced inflow/ infiltration from this source.
2. The roll off dumpster should be covered to prevent accumulation of
rainwater with the finished product.
3. Improved aeration of the digester could enhance volatile reduction.
4. Sand replacement, as needed, on drying beds could improve performance.
8.0 CONCLUSION
Serious consideration should be given to mechanical sludge thickening. This
would eliminate the need for liquid sludge hauling. A belt filter press on this location
would provide consistent solids management.

during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided
by the number of daily discharges sampled and/or measured during such week. It is,therefore,an arithmetic
mean found by adding the weights of pollutants found each day of the week and then dividing this sum by
the number of days the tests were reported. This limitation is identified as "Weekly Average"in Part I of the
permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If
only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum
daily discharge." This limitation is identified as"Daily Maximum,"in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured
during the calendar year on which daily discharges are sampled and measured,divided by the number of daily
discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding
the weights of pollutants found each day of the year and then dividing this sum by the number of days the
tests were reported. This limitation is defined as "Annual Average"in Part I of the permit.
6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria,is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar month on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured during such
month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average monthly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation
is identified as "Monthly Average"under"Other Limits" in Part I of the permit.

Part II
•
Page 2 of 11
• 6.b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily
•
discharges are sampled and measured divided by the number of daily discharges sampled and/or measured
during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal
to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted
by flow value) of all the samples collected during that calendar day. The average weekly count for fecal
coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This
limitation is identified as"Weekly Average"under"Other Limits"in Part I of the permit.
c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If
only one sample is taken during any calendar day the concentration of pollutant calculated from it is the
"Maximum Daily Concentration". It is identified as "Daily Maximum" under"Other Limits" in Part I of the
permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations
of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled
and measured divided by the number of daily discharges sampled and/or measured during such year
(arithmetic mean of the daily concentration values). The daily concentration value is equal to the
concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average yearly count for fecal coliform
bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is
identified as "Annual Average" under"Other Limits"in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved
oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one
dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average
concentration" for the discharge. It is identified as"daily average"in the text of Part I.
f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is
identified as"Quarterly Average Limitation"in the text of Part I of the permit.
g. A calendar quarter is defined as one of the following distinct periods:January through March, April through
June,July through September,and October through December.
7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is
determined as the arithmetic mean of the total daily flows recorded during the calendar month.
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the
sample and flow will be representative of the total discharge.
c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually
without interruption throughout the operating hours of the facility. Flow shall be monitored continually
except for the infrequent times when there may be no flow or for infrequent maintenance activities on the
flow device.
8. Types of Samples
a. Composite Sample:A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and
combined proportional to the rate of flow measured at the time of individual sample collection,or

•
Part II
Page 3 of 11
8. a. (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between
samples determined by a preset number of gallons passing the sampling point. Flow measurement
between sample intervals shall be determined by use of a flow recorder and totalizer, and the present
gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at
the treatment system,or
(3) a single,continuous sample collected over a 24-hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no greater than
once per hour,and the time interval between effluent grab samples shall be no greater than once per hour
except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases,
effluent grab samples may be collected at time intervals evenly spaced over the 24-hour period which are
equal in number of hours to the detention time of the system in number of days. However,in no case
may the time interval between effluent grab samples be greater than six (6) hours nor the number of
samples less than four(4) during a 24-hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes;
the grab sample can be taken manually. Grab samples must be representative of the discharge or the
receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided
by the number of individual values.
b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual
values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog
of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric
mean,values of zero(0) shall be considered to be one(1).
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its
respective flow divided by the summation of the respective flows.
10. Calendar Day: A calendar day is defined as the period from midnight of one day until midnight of the next day.
However, for purposes of this permit,any consecutive 24-hour period that reasonably represents the calendar day
may be used for sampling.
11. ,Hazardous Substance: A hazardous substance means any substance designated under 40 CFR Part 116
pursuant to Section 311 of the Clean Water Act.
12. Toxic Pollutant: A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean
Water Act.

Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the facility by the
Certification Commission, the permittee shall employ a certified wastewater treatment plant operator in
responsible charge (ORC) of the wastewater treatment facilities. Such operator must hold a certification of the
grade equivalent to or greater than the classification assigned to the wastewater treatment facilities by the
Certification Commission. The permittee must also employ a certified back-up operator of the appropriate type
and any grade to comply with the conditions of Tide 15A NCAC Chapter 8G .0200. The ORC of the facility
must visit each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding
weekends and holidays, and must properly manage and document daily operation and maintenance of the facility
and must comply with all other conditions of Tide 15A,NCAC Chapter 8G .0200. Once the facility is classified,
the permittee shall submit a letter to the Certification Commission which designates the operator in responsible
charge within thirty days after the wastewater treatment facilities are 50%complete.
2. Proper Operation and Maintenance
The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control
(and related appurtenances) which are installed or used by the permittee to achieve compliance with the
conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and
appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities
or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance
with the conditions of the permit.
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this permit.
4. Bypassing of Treatment Facilities •
a. Definitions
(1) "Bypass" means the known diversion of waste streams from any portion of a treatment facility including
the collection system,which is not a designed or established or operating mode for the facility.
(2) "Severe property damage" means substantial physical damage to property, damage to the treatment
facilities which causes them to become inoperable,or substantial and permanent loss of natural resources
which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not
mean economic loss caused by delays in production.

•
Part II '
Page 7 of 11
4.b. Bypass not exceeding limitations.
The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded,but
only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the
provisions of Paragraphs c.and d.of this section.
c. Notice
(1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior
notice, if possible at least ten days before the date of the bypass; including an evaluation of the
anticipated quality and affect of the bypass.
(2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II,
E. 6.of this permit. (24 hour notice).
d. Prohibition of Bypass
(1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee
for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life,personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime. This
condition is not satisfied if adequate backup equipment should have been installed in the exercise of
reasonable engineering judgment to prevent a bypass which occurred during normal periods of
equipment downtime or preventive maintenance;and
(C) The permittee submitted notices as required under Paragraph c.of this section.
(2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects,if
the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph
d. (1)of this section.
5. Upsets
a. Definition: "Upset" means an exceptional incident in which there is unintentional and temporary
noncompliance with technology based permit effluent limitations because of factors beyond the reasonable
control of the permittee. An upset does not include noncompliance to the extent caused by operational
error,improperly designed treatment facilities,inadequate treatment facilities,lack of preventive maintenance,
or careless or improper operation.
b. Effect of an upset: An upset constitutes an affirmative defense to an action brought for noncompliance
with such technology based permit effluent limitations if the requirements of paragraph c. of this condition
are met. No determination made during administrative review of claims that noncompliance was caused by
upset,and before an action for noncompliance,is final administrative action subject to judicial review.
c. Conditions necessary for a demonstration of upset: A permittee who wishes to establish the
affirmative defense of upset shall demonstrate, through properly signed,contemporaneous operating logs,or
other relevant evidence that:
(1)An upset occurred and that the permittee can identify the cause(s) of the upset;
(2)The permittee facility was at the time being properly operated;and
(3)The permittee submitted notice of the upset as required in Part II,E. 6. (b) (B) of this permit.
(4)The permittee complied with any remedial measures required under Part II,B.2.of this permit.
d. Burden of proof: In any enforcement proceeding the permittee seeking to establish the occurrence of an
upset has the burden of proof.

concerning the possibility of connecting the Town's collection system to the existing PY .
WWTP. The PY plant has lost a considerable amount of its hydraulic flow as a result of
recent product line closures. Such being the case, additional capacity now exists at the
PY WWTP, which has the capacity necessary to accept the wastewater currently treated
by the Lowell WWTP. Unfortunately, negotiations have broken down between PY and
the Town concerning this matter. If the Town does negotiate an agreement with PY to
accept and treat the Town's wastewater,the agreement should include a stipulation that
allows the Town to own and/or operate the PY WWTP should PY cease operation(shut
down) at some point in the future.
Subsurface: Insufficient area.

Subject: NPDES Permit Renewal Application
Permit NC0025861
Lowell \l-'WTP
Gaston County
Dear Mr. Hicks:
The NPDES Unit received your permit renewal application on December 1, 2000. Thank you for
submitting this package. The renewal request did not include a sludge management plan. Please submit
a description of sludge handling and disposal for this facility. The permit renewal cannot
be completed without this information.
The permit renewal for this facility will be assigned to a member of the NPDES Unit staff. That staff
member will contact you if further information is needed to complete the permit renewal. Please note that
the NPDES Unit has several vacant positions. This staff shortage has lasted for over a year and is delaying
all permit renewals. Our remaining permit writers are currently reviewing Authorizations to Construct,
speculative limit requests, major permit modifications and 201 plan updates ahead of permit renewals. This
is necessary due to a variety of factors, including mandatory deadlines in the statutes which govern our
program.
If this staff shortage delays reissuance of NC0025861 the existing requirements in your permit will remain
in effect until the permit is renewed (or the Division takes other action). We appreciate your patience and
understanding while we operate with a severely depleted staff. If you have any additional questions
concerning renewal of the subject permit, please contact me at [phone], extension 538.
Sincerely,
CML fiaotrrit
