Mike,
Good afternoon.
Thanks for the e-mail. Holiday designation was erroneously omitted for July 6 on our July DMR. The
City of Graham observed July 6 as the Independence Day holiday for employees. Due to this
observance, no data was collected for that day.
If you have any further questions, please contact me at my contact information below.

Hi Cris — Our database noted monitoring omissions (pH, D.O., temp and conductivity) for the week of 7/6-10. These daily
parameters were only reported four times that week on the DMR. Was just checking to see if the data was simply
omitted from the DMR or if it was not collected. Trying to head off a letter. Let me know what you find out. Holler back
if any questions. Thanks, Mike.

Subject: Compliance Evaluation Inspection
NPDES Permit No. NCO021211
Graham Wastewater Treatment Plant
Alamance County
Dear Mr. Quick:
Jenny Graznak of this office performed a Compliance Evaluation Inspection at the Graham Wastewater
Treatment Plant in Alamance County on July 9, 2015. Cris Routh, Operator in Responsible Charge (ORC),
was present for the inspection. This type of inspection consists of two basic parts: an in -office review of
facility files and monitoring data and an on -site inspection of the facility. This particular inspection
evaluated nine (9) areas, and observations from each area are addressed below:
1. Permit
The permit became effective on July 1, 2013 and will expire on May 31, 2016. The facility had a copy of
the current permit available on site during the inspection.
2. Self -Monitoring Program
A review of the monthly Discharge Monitoring Reports (DMRs) for the period of May 2014 through April
2015 showed only one violation of permit parameters in February 2015: an Ammonia Nitrogen violation
that resulted in a Notice of Deficiency from our office, dated May 7, 2015. All parameters appear to have
been sampled per the requirements of the permit.
3. Laboratory
The plant's on -site laboratory is certified for the following permit parameters: BOD, Residual Chlorine,
Fecal Coliform, Conductivity, Dissolved Oxygen, Ammonia Nitrogen, Total Phosphorus, pH, Total
Suspended Solids, Temperature, and Turbidity. All lab data, chain of custody forms, confirmation of
meter calibrations, and thermometer verification were available during the inspection. Shelby Smith is
the Lab Coordinator. Meritech, Inc. analyzes metals, Total Nitrogen, and Toxicity samples. Flow -
proportional composite samples are collected daily.
4. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis by
Instrument Specialists, Inc. Verification of the last calibration (April 9, 2014) was available for review.

5. Sludge Handling & Disposal
The City of Graham operates under Division of Water Resources Land Application permit #WQ0003824
for the removal of residuals. The City owns an 89 acre farm, divided into 10 fields, which is used solely
for the application of residuals. The Land Application program will be inspected by Division of Water
Resources later this month.
6. Operations & Maintenance
Operation and maintenance at the facility appear to be excellent. The plant analyzes and documents
daily process control data such as sludge volume, bacterial analysis, temperature, pH, dissolved oxygen,
alkalinity, etc. A daily operator's logbook is maintained at the plant and is signed during each shift.
Similar to last summer, the facility's clarifiers are showing signs of infiltration by Macrothrix, a
freshwater crustacean that is not commonly found in wastewater. According to operators, the freely
swimming Macrothrix has not had significant impacts to treatment, aside from a slight decrease in pH.
The Marcothrix was dormant during the winter, but returned when temperatures increased. Operators
believe that the Macrothrix infestation is the result of illegal dumping of pond -water.
7. Facility Site Review
The plant includes a mechanical bar screen, two primary clarifiers, extended aeration, four secondary
clarifiers, and sludge digesters and storage. Both of the primary clarifiers are operating at this time.
Only one aeration basin is currently in use. Two surface aerators run on staggered intervals. All four
secondary clarifiers are currently in service. The plant has an alkali feed system, which can deliver
caustic after primary clarification and/or during final clarification when necessary.
8. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was available
for review during the inspection. Paperwork appears to be well organized and maintained.
9. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream monitoring
requirements have been waived as long as the City of Graham remains a member of the Upper Cape
Fear River Basin Association.
The facility was found to be in compliance with NPDES Permit No. NC0021211. Please refer to the
attached checklist for specific details from the inspection. If you have any questions concerning this
report, please contact Ms. Graznak or me at [phone].

Graham Wastewater Treatment Plant
Alamance County
Dear Mr. Quick:
Jenny Graznak of this office performed a Compliance Evaluation Inspection at the Graham
Wastewater Treatment Plant in Alamance County on July 17, 2014. Cris Routh, Operator in
Responsible Charge (ORC), was present for the inspection. This type of inspection consists of two
basic parts: an in -office review of facility files and monitoring data and an on -site inspection of the
facility. This particular inspection evaluated nine (9) areas, and observations from each area are
addressed below:
1. Permit
The permit became effective on July 1, 2013 and will expire on May 31, 2016. The facility had a
copy of the current permit available on site during the inspection.
2. Self -Monitoring Program
A review of the monthly Discharge Monitoring Reports (DMRs) for the period of June 2013 through
May 2014 showed no violations of permit parameters. In addition, all parameters appear to be
sampled per the requirements of the permit.
3. Laboratory
The plant's on -site laboratory is certified for the following permit parameters: BOD, Residual
Chlorine, Fecal Coliform, Conductivity, Dissolved Oxygen, Ammonia Nitrogen, Total Phosphorus, pH,
Total Suspended Solids, Temperature, and Turbidity. All lab data, chain of custody forms,
confirmation of meter calibrations, and thermometer verification were available during the
inspection. Shelby Smith is the Lab Coordinator. Meritech, Inc. analyzes metals, Total Nitrogen,
and Toxicity samples. Flow -proportional composite samples are collected daily.
4. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis by
Instrument Specialists, Inc. Verification of the last calibration (April 17, 2014) was available for
review.

5. Sludge Handling & Disposal
The City of Graham operates under Division of Water Resources Land Application permit
#WQ0003824 for the removal of residuals. The City owns an 89 acre farm, divided into 10 fields,
which is used solely for the application of residuals. The Land Application program was inspected by
Division of Water Resources on July 10, 2014.
6. Operations & Maintenance
Cris Routh is the ORC, and the Back -Up ORC is Victor Quick. Operation and maintenance at the
facility appear to be excellent. The plant analyzes and documents process control data. such as
sludge volume, bacterial analysis, temperature, pH, dissolved oxygen, alkalinity, etc. A daily
operator's logbook is maintained at the plant and is signed during each shift.
At the time of the inspection, the clarifiers had recently been infiltrated by Macrothrix, a
freshwater crustacean that is not commonly found in wastewater. According to operators, the
freely swimming Macrothrix has not had significant impacts to treatment, aside from a slight
decrease in pH. Operators have not been able to rid the plant of the Macrothrix.
7. Facility Site Review
The plant includes a mechanical bar screen, two primary clarifiers, extended aeration, four
secondary clarifiers, and sludge digesters and storage. Both of the primary clarifiers are operating
at this time. Only one aeration basin is currently in use. Two surface aerators run 20 minutes on/10
minutes off, at staggered intervals. All four secondary clarifiers are currently in service. The plant
has a alkali feed system, which can deliver caustic after primary clarification and/or during final
clarification when necessary.
8. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection. Paperwork appears to be well organized and maintained.
9. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream monitoring
requirements have been waived as long as the City of Graham remains a member of the Upper
Cape Fear River Basin Association.
The facility was found to be in compliance with NPDES Permit No. NC0021211. Please refer
to the attached report for specific details from the inspection. If you have any questions
concerning this report, please contact Ms. Graznak or me at [phone].

Please read the inquiry below. Do you know of another community using this process?
Graham is buying a heated sludge press, which filters wastewater. The reporter's trying to locate another town in N.C.
that has used one of these mechanisms so he can interview someone in that town to find out how the press worked and
any bad side effects it may have had. Apparently, folks in the area are wary of the town's intentions to buy one of these
things because they're afraid it will create a big stink in the area. The reporter wants to find out if that's true, based on
what another town may have experienced using the same technology. Are you aware of another town has recently
bought/installed one of these mechanisms?

Jenny Graznak of this office performed a Compliance Evaluation Inspection at the Graham
Wastewater Treatment Plant in Alamance County on August 21, 2013. Cris Routh, Operator in
Responsible Charge (ORC), was present for the inspection. This type of inspection consists of two
basic parts: an in -office review of facility files and self -monitoring data and an on -site inspection of
the facility. This particular inspection evaluated nine (9) areas, and observations from each area are
addressed below:

The permit became effective on July 1, 2013 and will expire on May 31, 2016. This new permit
reduced the monitoring frequency for fecal coliform, TSS, Ammonia Nitrogen, and BOD from daily to
two times per week. Additionally, monthly monitoring for lead, copper, zinc, and mercury was
removed from this permit.
2. Self -Monitoring Program
A review of the self -monitoring data submitted for the period of June 2012 through May 2013
showed that all parameters were sampled and analyzed per the requirements of the permit. Several
limit violations occurred in September 2012, which were addressed in previous correspondence from
this office. Please see the attached list of the plant's violations during this time period.
3. Laboratory
The plant's on -site laboratory (#240) is certified for the following permit parameters: BOD, Residual
Chlorine, Fecal Coliform, Conductivity, Dissolved Oxygen, Ammonia Nitrogen, Total Phosphorus,
pH, Total Suspended Solids, Temperature, and Turbidity. All lab data, chain of custody forms,
confirmation of meter calibrations, and thermometer verification were available during the inspection.
Shelby Smith is the Lab Coordinator. Meritech, Inc. analyzes metals, Total Nitrogen, and Toxicity
samples. Flow -proportional samples are collected by an effluent ISCO sampler.
4. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis by
Instrument Specialists, Inc. Verification of calibration was available during the inspection. According
to documentation, the last calibration event occurred on July 30, 2013.

5. Sludge Handlinq & Disposal
The City of Graham operates under Land Application permit (WQ0003824) from the Division of
Water Resources for the removal of residuals from the sludge digesters at the plant. The City owns
an 89 acre farm, divided into 10 fields, which is used solely for the application of residuals. Staff
from Division of Water Resources from the inspected this plant on August 8, 2013 and found them to
be compliant with the requirements of the Land Application permit.
6. Operations & Maintenance
Cris Routh is the ORC, and the Back -Up ORC is Victor Quick. Operation and maintenance at the
facility appear to be excellent. The plant analyzes and documents process control data such as
sludge blanket, bacterial analysis, temperature, pH, dissolved oxygen, alkalinity, etc. A daily
operator's logbook is maintained at the plant and is signed during each shift.
The plant operates a preventative maintenance computer program called Hach JOB Cal. The
maintenance staff issues work orders once per month and more frequently for repairs, etc. Each
time a cylinder of chlorine or sulfur dioxide gas is replaced, a checklist is completed for safety and
maintenance purposes. A SCADA system is used to monitor and control some operations at the
plant, including pump stations.
The site has two generators. The 800-kW generator can operate the plant starting from the primary
clarifiers and is exercised monthly under full load. The 400-kW generator is set on a timer to
exercise twice per month and can operate the pumps in the wet well that transfer influent to the
primary clarifiers. Cummins Atlantic visits the plant twice a year to service the generators.
7. Facility Site Review
The plant includes a mechanical bar screen, two primary clarifiers, extended aeration, four
secondary clarifiers, and sludge digesters and storage. Both of the primary clarifiers are operating at
this time. Only one aeration basin is currently in use. Two surface aerators run 20 minutes on/10
minutes off, at staggered intervals. All four secondary clarifiers are currently in service. The plant has
a new alkali feed system, which can deliver caustic after primary clarification and/or during final
clarification when necessary.
8. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection. Paperwork appears to be well organized and maintained.
9. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream monitoring
requirements have been waived as long as the City of Graham remains a member of the Upper
Cape Fear River Basin Association.
The facility was found to be in compliance with NPDES Permit No. NCO021211. Please refer
to the attached report for specific details from the inspection. If you have any questions concerning
this report, please contact Ms. Graznak or me at [phone].

BACKGROUND
The City Of Graham WWTP is a Class IV facility with a permitted flow of 3.5 MGD. The average
flow for the past three years (2010-2012) has been 1.24 MGD. The permit was originally issued on
May 29, 2006 with an expiration date of May 31, 2011. Several modifications were issued: one on
October 20, 2006 which reduced nutrient monitoring to weekly; one on July 9, 2010 which
included the Jordan Reservoir Nutrient Management Strategy Rules; and one on August 9, 2010
which included some technical revisions. The expired permit has been administratively continued
until the permit is renewed and issued. The Permittee submitted EPA Form 2A on November 29,
2010 in order to request renewal of the permit.
The City of Graham has four significant industrial users and a full pretreatment program with the
Division of Water Quality's Pretreatment Unit. The City will be required to continue to implement
this program in the new permit term.
STREAM CONDITIONS
This facility discharges to the Haw River in subbasin 03-06-02, in the Cape Fear River Basin. This
portion of the Haw River was reclassified from C NSW waters to WS-V NSW waters as part of the
Jordan Lake Wastewater Discharge Rule (15A NCAC 02B .0270). This segment of the Haw River
is not listed on the 2012 North Carolina 303(d) Impaired Waters List.
Note that on July 16, 2012 the NC Governor signed Senate Bill 810 which clarified that "nutrient
management strategies for B. Everett Jordan Reservoir and the Falls of the Neuse Reservoir
watersheds shall not be interpreted to apply surface water quality standards set out in 15A NCAC
2B .0218(3)(e) through (3)(h) to waters designated in the nutrient management rules as WS-V
except where: ............. are classified as WS-H, WS-III, or WS-IV." Therefore, water quality
Fact Sheet
NPDES NCO024881 Renewal
Paee I

water supply standards outlined in 15A NCAC 2B .0218(3)(e) through (3)(h) do not apply in this
segment of the Haw River.
Instream monitoring is waived as long as this facility is a member of the Cape Fear River Basin
Association. If the facility ends its membership in the Association, instream monitoring
requirements as specified in this permit take effect immediately.
BOD s and NH,,-N
In 1989 the facility relocated its discharge point from Town Branch Creek to the Haw River. A
Waste Load Allocation was performed which determined limitations for BOD5 at 12 mg/L in the
summer and 24 mg/L in the winter. Limitations for NH3-N were determined to be 4 mg/L in the
summer and 8 mg/L in the winter. A Waste Load Allocation was performed on NH3-N for this
permit renewal and at current limits the receiving stream is protected from ammonia -nitrogen
toxicity. It is recommended that current limitations for BOD5 and NH3-N remain in the permit.
REASONABLE POTENTIAL ANALYSIS
Reasonable Potential Analyses were conducted for: As, Cd, CN, Cr, Cu, Pb, Mo, Ni, Ag, Se, and
Zn (see the results of the RPA and parameter recommendations attached). Effluent samples from
Jan. 2010 through Dec. 2012 showed no reasonable potential to violate WQS. Monitoring for Pb,
Cu, and Zn was removed from the permit, however, the City is required to continue sampling all
twelve metals as part of its Pretreatment Long Term Monitoring Program (LTMP).
TOXICITY TESTING:
The facility has passed all 20 of its toxicity tests performed since 2008. It is recommended that they
continue to perform whole effluent chronic toxicity tests, pass/fail at a 14% effluent concentration,
March, June, September and December.
COMPLIANCE SUMMARY
DMRs have been reviewed for the period January 2008 through December 2012. During the
review period, the following NOVs (notices of violation) have been issued: 12/19/2012 for pH,
DO, TSS, BOD, and Fecal Coliform; 7/7/2008 for NH3 N and BOD. The 2012 non-compliance
issues were due to a surge of caustic wastewaters and the WWTP had to be reseeded. The
permittee was not able to prove what industry caused the impact.
A Compliance Evaluation Inspection conducted on 8/29/2012 found the facility satisfactory. A
Pretreatment Compliance inspection performed on 10/31/2012 found the facility very reliable with
no compliance issues.
MERCURY MINIMIZATION PLAN (MMP)
In accordance with the NPDES Permitting Guidance for Implementation of the 2012 Statewide
Mercury TMDL, the past five years of mercury sampling data were evaluated (2008-2012). All
five annual averages were less than the allowable Water Quality Based Limit and no samples
exceeded the Technology Based Effluent Limit of 47 ng/L. As a result, no permit limit is required.
Multiple samples did exceed 1 ng/L and as a WWTP with a flow > 2 mgd, the facility will be
required to develop and implement a MMP and conduct mercury monitoring as part of its Effluent
Pollutant Scans.
PROPOSED CHANGES
• The stream classification in the Supplement to Cover page was revised to show that the Haw River
was reclassified from C; NSW waters to WS-V; NSW waters as part of the Jordan Lake
Wastewater Discharge Rule (15A NCAC 02B .0270).
Fact Sheet
NPDES NCO024881 Renewal
Page 2

I
• Pb, Cu, and Zn effluent sampling data did not show reasonable potential to violate water quality
standards. All three parameters have been removed from the permit but will continue to be
monitored as part ofithe City's Pretreatment LTMP.
• Hg is not showing potential to violate the WQBEL or the TBEL so the monitoring requirement was
removed from Section A.(1) Effluent Limitations and Monitoring Requirements. Since multiple
samples did exceed 1 ng/L the facility is required to develop and implement a MMP and conduct
mercury monitoring as part of the Effluent Pollutant Scans. MMP requirements have been added to
the permit under Section A.(7.)
• A Total Nitrogen limitation and footnote have been added on the TN mass load limitation in
Section A. (L) in order to recognize Session Law 2011-394, H.B. 119 as listed in the Nutrient
Allocations Sections of the current and draft permits.
• The Effluent Pollutant Scan in Section A.(4) has been modified to request the specific three years
the facility is expected to perform its annual scans.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
Draft Permit to Public Notice: March 20, 2013 (estimate)

Monitoring for mercury will occur as part
of the Effluent Pollutant Scans. The POTW
discharges > 2 MGD (permitted flow 3.5
MGD) and mercury was detected in
concentrations greater than 1 ng/L on
multiple occassions, therefore a MMP is
required.

Facility Class IV
Dear Mr. Quick:
Enclosed with this letter is a copy of the draft permit for your facility. Please review the draft
very carefiilly to ensure thorough understanding of the conditions and requirements it contains.
The draft permit contains the following significant changes from your current permit:
• The stream classification in the Supplement to Cover was revised from C NSW to WS-V
NSW in accordance with the Jordan Lake Wastewater Discharge Rule (15A NCAC 02B
.0270).
• Effluent sampling data for lead, copper, and zinc did not show reasonable potential to violate
Water Quality Standards. Monitoring for all three parameters has been removed from the
permit, however, the City is expected to continue monitoring these parameters as part of its
Pretreatment Long Term Monitoring Program (LTMP).
• A Total Nitrogen limitation and footnote have been added to the effective date on the TN
mass load limitation in Section 1. (1.) in order to recognize Session Law 2011-394, H.B. 119.
• In accordance with NPDES Permitting Guidance for the 2012 Statewide Mercury TMDL,
five years of effluent mercury data was reviewed. Annual average effluent mercury
concentrations were less than the Water Quality Based Effluent limitation and the
Technology Based Effluent Limitation, therefore, no limit was required. Monthly monitoring
requirements have been removed and mercury monitoring shall continue as part of the
Effluent Pollutant Scans. As part of implementing the Statewide Mercury TMDL, a Mercury
Minimization Plan must be developed for your facility. See new Special Condition A. (7).
The requirements are posted on our website: http://portal.ncdenr.or web/wq//Xs/npdes. You
will have 180 days from the effective date of this permit to develop the plan.
• Section A. (9.) Effluent Pollutant Scan has been modified and now specifies the three years
the facility is expected to perform its annual scans.

Footnote #5 was amended under Section A.(l.) to include the following statement: Limit and
monitoring apply only if chlorine or chlorine derivatives are used for disinfection. The
Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance
with the permit. However, the Permittee shall record and submit all values reported by a
North Carolina certified laboratory (including field certified), even if these values fall below
50 µg/L.
The wording in Section A. (8.) has been changed and the following paragraph added: If the
Permittee monitors any pollutant more frequently then required by this permit, the results of
such monitoring shall be included in the calculation and reporting of the data submitted on
the Discharge Monitoring Report and all AT Forms submitted.

Re: Nitrogen Optimization Progress Report
City of Graham Wastewater Treatment Plant
NPDES Permit No. NCO021211
In accordance with the City of Graham's NPDES Permit section A. (7.) Nitrogen
Optimization, the City is required to submit a progress report to the Division, documenting the
status of the proposed measures and the nitrogen reduction achieved at the City's POTW
facility during the previous calendar year. This is to be submitted one year following the
Division's written acceptance of the previously submitted Nitrogen Optimization Plan. The
required Nitrogen Optimization Plan was submitted to the Division on February 4, 2010 for the
2009 calendar year and January 28, 2011 for the 2010 calendar year. The City of Graham has
not received written acceptance from the Division for either of these plans for the last two
years.
The City of Graham continues to comply with the 2016 Total Nitrogen allocation
requirements. In an effort to further reduce Total Nitrogen and obtain additional alkalinity for
reduction in Total Phosphorus, the City has retained Hazen & Sawyer to evaluate our current
treatment process to determine if it is possible to achieve additional reduction in Total Nitrogen
with the City's existing infrastructure. Plans are currently in the design phase to install an alkali
feed system to enhance the reduction of Total Phosphorus and installation of a Nitrate and
Ammonia probe based aeration control system to aid in the further reduction of Total Nitrogen.
During calendar year 2011 the City's POTW performed well in terms of the Total Nitrogen

discharged to the Jordan Lake Watershed. As evidenced by the City's Discharge Monitoring
Reports, the Annual Mass Load of Total Nitrogen for the 2011 calendar year was compliant with
the Jordan Lake Rules Total Nitrogen 2016 mass load allocation.
The City of Graham continues to evaluate its treatment facilities and operational
processes to make a reasonable effort to reduce nitrogen discharges into the Jordan Lake
Watershed. Should the Division have any questions regarding this Annual Progress Report,
please contact me.

Subject: Compliance Evaluation Inspection — NPDES Permit No. NCO021211
City of Graham Wastewater Treatment Plant — Alamance County
Dear Mr. Quick:
Dee Freeman
Secretary
Jenny Graznak of this office performed a Compliance Evaluation Inspection at the Graham
WWTP in Alamance County on August 29, 2012. Cris Routh, Operator in Responsible Charge
(ORC), was present for the inspection. This type of inspection consists of two basic parts: an in -
office review of facility files and self -monitoring data and an on -site inspection of the facility. This
particular inspection evaluated nine (9) areas, and observations from each area are addressed
below:
1. Permit
The permit expired on May 31, 2011. Since the new permit has not been issued by Division of
Water Quality yet, you should continue to operate according to the old permit.
2. Self -Monitoring_ Program
A review of the self -monitoring data submitted for the period June 2011 through May 2012 showed
that all parameters were sampled and analyzed per the requirements of the permit. There were no
violations of permit limits during this time period.
3. Laboratory
The plant's on -site laboratory (#240) is certified for the following permit parameters: BOD, Residual
Chlorine, Fecal Coliform, Conductivity, Dissolved Oxygen, Ammonia Nitrogen, Total Phosphorus,
pH, Total Settleable Residue, Total Suspended Residue, Temperature, and Turbidity. All lab data,
chain of custody forms, confirmation of meter calibrations, and thermometer verification were
available during the inspection. Shelby Smith is the Lab Coordinator. Meritech, Inc. analyzes
metals, Total Nitrogen, Mercury, and Toxicity samples. Flow -proportional samples are collected by
an effluent ISCO sampler.
4. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis by
Instrument Specialists, Inc. Verification of calibration was available during the inspection. According
to documentation, the last calibration event occurred on July 31, 2012.
5. Sludge Handling & Disposal
The City of Graham has Land Application permit (WQ0003824) with DWQ Aquifer Protection Section
for the removal of residuals from the sludge digesters at the plant. The City owns an 89 acre farm,
divided into 10 fields, which is used solely for the application of residuals. The City transported
approximately 2.4 million gallons in 2011.

6. Operations & Maintenance
Cris Routh is the ORC for Graham WWTP, and the Back -Up ORC is Victor Quick. The plant
analyzes the following process control data: daily sludge volume, bacterial analysis of the aeration
basin three times per week, and weekly digester data such as temperature, pH, dissolved oxygen,
alkalinity, etc. A daily operator's logbook is maintained at the plant and is signed during each shift.
Scott Jennings is the Maintenance Supervisor. The plant operates a preventative maintenance
computer program called Hach JOB Cal. The maintenance staff issues work orders once per month
and more frequently for repairs, etc. Each time a cylinder of chlorine or sulfur dioxide gas is
replaced, a checklist is completed for safety and maintenance purposes. A SCADA system is used
to monitor and control some operations at the plant, including pump stations.
7. Facility Site Review
The plant includes grit removal, two primary clarifiers, two extended aeration basins, four secondary
clarifiers, and sludge digesters and storage. Both of the primary clarifiers are operating at this time.
Only one aeration basin is currently in use. Two surface aerators run 20 minutes on/10 minutes off,
at staggered intervals. All four secondary clarifiers are currently in service. The site has two
generators. The 800-kW generator (which can operate the entire plant) runs on the second
Wednesday of each month under full load, when the plant staff shuts off the main power. The 400-
kW generator (which operates the wet well) runs automatically for 20 minutes every two weeks for
maintenance purposes but not under load.
8. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection.
9. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream monitoring
requirements have been waived as long as the City of Graham remains a member of the Upper
Cape Fear River Basin Association.
During her site visit, Ms. Graznak also performed a Stormwater Inspection at the Graham
WWTP. The facility holds General Stormwater Permit No. NCG110021 under the National Pollutant
Discharge Elimination System (NPDES) to discharge Stormwater from "Treatment Works." The
Stormwater Pollution Prevention Plan (SPPP) is current and complete. Operations staff perform the
semi-annual visual monitoring at each of the plant's five stormwater discharge outfalls. Each of the
five outfalls is properly labeled and showed no signs of issues or problems.
The facility was found to be in compliance with NPDES Permit No. NCO021211 and NPDES
General Permit No. NCG110021. Please refer to the attached report for specific details from the
inspection. If you have any questions concerning this report, please contact Ms. Graznak or me at
[phone].

Dear Mr. Quick:
A letter of request for an Authorization to Construct was received February 27, 2012, by
the Division of Water Quality (Division), and final plans and specifications for the subject
project have been reviewed and found to be satisfactory. Authorization is hereby granted for the
construction of modifications to the existing 3.5 MGD Wastewater Treatment Plant, with
discharge of treated wastewater into the Haw River in the Cape Fear River Basin.
This authorization results in no increase in design or permitted capacity and is awarded
for the construction of the following specific modifications:
Installation of a caustic (sodium hydroxide) storage facility to include four (4) 330
gallon intermediate bulk containers (IBC's) and a containment slab with drain; a
chemical feed pump station to be housed in the existing RAS pump station #1
with two (2) .5-8 gph peristaltic metering pumps capable of pumping sodium
hydroxide to both the primary clarifier and secondary clarifier effluent application
points, in conformity with the project plans, specifications, and other supporting
data subsequently filed and approved by the Department of Environment and
Natural Resources.
This Authorization to Construct is issued in accordance with Part III, Paragraph A of

The results must be put on the DMR as they are reported by the lab.
As for the calculation, I think they should report to 1 decimal place for NO2+NO3 and Total N.

Subject: RE: Outside Lab results
Jenny,
Good morning.
I'm still a bit confused about the digits so I'll give you an example of what I'm talking about. Below are the April results
so far from our outside Lab concerning our Plant Effluent Composite:
TKN m L NO2+NO3 (mg/L) Nitrogen, Total (mg/L)
April 3 1.45 0.57 2.02

April 10 1.41 3.54 4.95
April 17 1.08 11.9 13.0
Averaging the results on the DMR for TKN is not an issue; all results are to 2 decimal places. The issue arises with the
results for NO2+NO3 and Total Nitrogen. The April 3 and April 10 results are both to 2 decimal places but the April 17
results are only to 1 decimal place.
(1) Should I report the results on the DMR as they are reported to us from our outside lab even though the decimal
places are inconsistent?
Example #1, April 17: 1.08 + 11.9=12.98, or 13.0 as reported.
(2) When the results for NO2+NO3 and Total Nitrogen are averaged, should I report them to 1 or 2 decimal places?
Example #1, NO2+NO3: (0.57 + 3.54 + 11.9)/3 = 16.01 or 16.0.
Example #2a, Total Nitrogen: (2.02 + 4.95 + 13.0)/3 = 6.66 or 6.7
Example #2b, Total Nitrogen: (2.02 + 4.95 + 12.98)/3 = 6.65 or 6.7
It seems kind of trivial, but I just want to make sure I'm consistent and on the same page with the state. Thanks.

Dear Ms. Graznak:
On the evening of Saturday, March 24, 2012, the City of Graham
Wastewater Treatment Plant experienced a spill within our plant. Between the
hours of 7:00 p.m. and 9:00 p.m., an estimated 1.5 inches of rain fell in the
Graham area. This amount of rain plus the fact that our plant was already in
High Flow Operations due to heavy rains earlier that morning, caused a surge in
the flow entering our facility. The result was a sudden rise of the water levels in
our secondary clarifiers causing an overflow of our #3 secondary clarifier. Within
30 minutes, the additional operation of another recirculation pump quickly
brought the situation under control but not until approximately 3,120 gallons of
treated wastewater had spilled into the grassy areas around the clarifier.
Hydrated lime was applied to the affected areas and we have made changes to
our High Flow Operating Procedure that should help the plant to prevent a
situation like this from occurring in the future. In accordance with House Bill
1160, a news release was issued to the Burlington Times -News newspaper on
March 27, 2012 regarding the wastewater spill.
If, additional information is required, please let me know. I can be reached
at 336.570.6721.
Sincerely,

Subject: Compliance Evaluation Inspection — NPDES Permit No. NCO021211
City of Graham Wastewater Treatment Plant — Alamance County
Dear Mr. Quick:
Jenny Graznak of this office performed a Compliance Evaluation Inspection at the Graham
WWTP in Alamance County on August 3, 2011. Cris Routh, Operator in Responsible Charge
(ORC), was present for the inspection. This type of inspection consists of two basic parts: an in -
office review of facility files and self -monitoring data and an on -site inspection of the facility. This
particular inspection evaluated nine (9) areas, and observations from each area are addressed
below:
1. Permit
The permit became effective December 1, 2006 and expired May 31, 2011. The new permit has not
been issued by Division of Water Quality yet, so you should continue to operate according to the old
permit.
2. Self -Monitoring Program
A review of the self -monitoring data submitted for the period June 2010 through May 2011 showed
that all parameters were sampled and analyzed per the requirements of the permit. There were no
violations of permit limits during this time period.
3. Laboratory
The plant's on -site laboratory (#240) is certified for the following permit parameters: BOD, Residual
Chlorine, Fecal Coliform, Conductivity, Dissolved Oxygen, Ammonia Nitrogen, Total Phosphorus,
pH, Total Settleable Residue, Total Suspended Residue, Temperature, and Turbidity. All lab data,
chain of custody forms, confirmation of meter calibrations, and thermometer verification were
available during the inspection. Shelby Smith is the Lab Coordinator. Meritech, Inc. analyzes
metals, Total Nitrogen, Mercury, and Toxicity samples. Flow -proportional samples are collected by
effluent ISCO samplers.
4. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis by
Instrument Specialists, Inc. Verification of calibration was available during the inspection. According
to documentation, the last calibration event occurred on July 18, 2011.
5. Sludge Handling & Disposal
The City of Graham has Land Application permit (WQ0003824) with DWQ Aquifer Protection Section
for the removal of residuals from the sludge digesters at the plant. The City owns an 89 acre farm,

divided into 10 fields, which is used solely for the application of residuals. The City transported
approximately 2.5 million gallons in 2010.
6. Operations & Maintenance
Cris Routh is the ORC for Graham WWTP, and the Back -Up ORC is Victor Quick. The plant
analyzes the following process control data: daily sludge volume, bacterial analysis of the aeration
basin three times per week, and weekly digester data such as temperature, pH, dissolved oxygen,
alkalinity, etc. A daily operator's logbook is maintained at the plant and is signed during each shift.
Scott Jennings is the Maintenance Supervisor. The plant operates a preventative maintenance
computer program. The maintenance staff issues work orders once per month and more frequently
for repairs, etc. Each time a cylinder of chlorine or sulfur dioxide gas is replaced, a checklist is
completed for safety and maintenance purposes. A SCADA system is used to monitor and control
some operations at the plant, including pump stations.
7. Facility Site Review
The plant includes grit removal, two primary clarifiers, two extended aeration basins, four secondary
clarifiers, and sludge digesters and storage. Both of the primary clarifiers are operating at this time.
Only one aeration basin is currently in use. Two surface aerators run every 25-30 minutes, at
staggered intervals. All four secondary clarifiers are currently in service. The site has two
generators. The 800-kW generator (which can operate the entire plant) runs on the second
Wednesday of each month under full load, when the plant staff shuts off the main power. The 400-
kW generator runs automatically for 20 minutes every two weeks for maintenance purposes but not
under load.
8. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection.
9. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream monitoring
requirements have been waived as long as the City of Graham remains a member of the Upper
Cape Fear River Basin Association.
The facility was found to be in compliance with NPDES Permit No. NC0021211. Please refer
to the attached report for specific details from the inspection. If you have any questions concerning
this report, please contact Ms. Graznak or me at [phone].

Description of Collection System and Treatment Process
The City of Graham operates a Public Owned Treatment Works consisting
of a North Carolina Grade II Collection System and a North Carolina Grade IV
Wastewater Treatment Plant.
The collection system operates under a North Carolina Division of Water
Quality Collection System Permit and contains approximately 89 miles of piping
and seven lift stations. The lift stations are named Back Creek No. 1, Back
Creek No.2, Boyd Creek, Cherry Lane, Haw River, Old Fields, and Prytle Drive.
The wastewater treatment facility has a permitted flow of 3.5 million
gallons per day (MGD). This facility consists of bar screens, grit collectors,
primary clarification, extended aeration, final clarifiers, sand filtration,
chlorination, post chlorination basin, de -chlorination, digestion, lime stabilization,
sludge disposal, and laboratory. Effluent is discharged to the Haw River
designated as Nutrient Sensitive Waters (NSW), which is part of the Cape Fear
River Basin.

Pr -
Performance
Text Summary of the System Performance for the Period of July 1, 2010 to June
30, 2011.
Collection System: The collection system had No sanitary sewer overflows that
were reportable to the North Carolina Department of Environment and Natural
Resources, Division of Water Quality. Over 10% of the collection system was
hydraulically cleaned. Approximately 16,000 linear feet of pipe was chemically
treated to prevent root infiltration and approximately 13,000 linear feet of pipe
was inspected with closed circuit television camera. All of the City's sewer
easements were inspected and mowed twice.
Lift Stations: The City of Graham operates seven lift stations that are
maintained by plant maintenance personnel. During this reporting period, the lift
stations had one reportable sewer overflow.
Wastewater Treatment Plant: The Wastewater Treatment Plant had two
violations of its NPDES permit. The City's NPDES permit has limits on Flow,
Biological Oxygen Demand, Total Suspended Solids, Ammonia, Dissolved
Oxygen, Fecal Coliform, Chronic Toxicity, and Total Phosphorus. Additional
testing is performed for Total Residual Chlorine, Temperature, Conductivity,
Copper, Mercury, and Zinc. Each month this data is reported to the state thru the
Discharge Monitoring Report (DMR). The City is a member of The Upper Cape
Fear River Basin Dischargers Coalition that performs monitoring upstream and
downstream of our discharge point on the Haw River as well as other locations
on the Haw and Deep Rivers.
Non -Discharge Permit: The City of Graham land applies biosolids to agricultural
land under regulations of the Environmental Protection Agency and the State of
North Carolina. There were No violations.
Violations of permit conditions or other environmental
regulations relating to water quality from the above areas
July, 2010. NPDES PERMIT: The Wastewater Plant had a permit violation for
monthly Ammonia average. The limit is a monthly average of 4.0 milligrams per
liter (mg/L) of effluent. The City's average for the month of July, 2010 was 4.76
mg/L. Repairs to faulty equipment corrected the problem and brought the plant
back into compliance.
November 6, 2010. SEWER OVERFLOW: The City of Graham had a
wastewater spill of an estimated 300,000 gallons. The untreated wastewater
spilled into "Boyd Creek" in the Cape Fear River Basin. The spill was a result of
lift station pump failure due to vandalism. Repairs and security measures were
2

made and service restored. A Vandalism report was filed with Graham Police
Department.
November 8, 2011. NPDES PERMIT: Daily Residual Chlorine was above the
permit limit for November 8, 2010. The allowable daily limit is 50 ug/L and the
reported value was 61 ug/L. The cause of the violation was determined to be a
faulty Chlorine Residual analyzer when operated in the auto mode. Changes
made to the operation of the Chlorine chemical feed system corrected the issue.
SUMMARY
During this 12-month period, there were two NPDES permit violations out
of more than 2,400 sample results.
The City of Graham had only one reportable sanitary sewer overflow of
1000 gallons or more during this reporting period. The total gallons of overflow
were 300,000. Total gallons handled by the system were 425,841,000. Percent
gallons overflowed are 300,000 divided by 425,841,000 x 100% = 0.07 per cent.
Therefore, the City of Graham achieved a 99.93 % successful collection rate of
all water discharged into the system.
All sludge was land applied per Land Application Permit regulations with
no permit violations.

Subject: Compliance Evaluation Inspection — NPDES Permit No. NCO021211
City of Graham Wastewater Treatment Plant — Alamance County
Dear Mr. Quick:
Jenny Graznak of this office performed a Compliance Evaluation Inspection at the
Graham WWTP in Alamance County on March 31, 2010. Cris Routh, Operator in Responsible
Charge (ORC), was present for the inspection. This type of inspection consists of two basic
parts: an in -office review of facility files and self -monitoring data and an on -site inspection of the
facility. This particular inspection evaluated nine (9) areas, and observations from each area
are addressed below:
1. Permit
The permit became effective December 1, 2006 and expires May 31, 2011. A complete copy of
the permit was available for review during the inspection.
2. Self -Monitoring Program
A review of the self -monitoring data submitted for the period January 2009 through December
2009 showed that all parameters were sampled and analyzed per the requirements of the
permit. There were no violations of permit limits during this time period.
3. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis
by Instrument Specialists, Inc. The influent flow meter was last calibrated on January 31, 2010,
and verification of calibration was available during the inspection.
4. Facility Site Review
The plant includes grit removal, two primary clarifiers, two extended aeration basins, four
secondary clarifiers, and sludge digesters and storage. Both of the primary clarifiers are
operating at this time. Only one aeration basin is currently in use. Two surface aerators run
every 25-30 minutes, at staggered intervals. One of the four secondary clarifiers is out of
service. The site has two generators. The 800-kW generator (which can operate the entire
plant) runs on the second Wednesday of each month under full load, when the plant staff shuts
off the main power. The 400-kW generator runs automatically for 20 minutes every two weeks
for maintenance purposes but not under load.

5. Operations & Maintenance
Cris Routh is the new ORC for Graham WWTP, replacing David Lawson who retired in late
2009. The plant analyzes the following process control data: daily sludge volume, bacterial
analysis of the aeration basin three times per week, and weekly digester data such as
temperature, pH, dissolved oxygen, alkalinity, etc. A daily operator's logbook is maintained at
the plant and is signed during each shift. Scott Jennings is the Maintenance Supervisor. The
plant operates a preventative maintenance computer program. The maintenance staff issues
work orders once per month and more frequently for repairs, etc. Each time a cylinder of
chlorine or sulfur dioxide gas is replaced, a checklist is completed for safety and maintenance
purposes. A SCADA system is used to monitor and control some operations at the plant,
including pump stations.
Ms. Graznak observed that housekeeping has improved at the plant since the inspection in
2009. The weirs on the clarifiers were free of solids, and fewer floating solids were noted in the
chlorine contact chamber. There is also a new dumpster to contain the bar screenings.
6. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream
monitoring requirements have been waived as long as the City of Graham remains a member of
the Upper Cape Fear River Basin Association.
7. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection.
8. Laboratory
Meritech, Inc. analyzes metals, total nitrogen, and mercury for the plant. The facility's on -site
laboratory provides analysis for all other parameters. The lab coordinator is Shelby Smith.
Flow -proportional samples are collected by effluent ISCO samplers.
9. Sludge Handling & Disposal
The City of Graham has Land Application permit (WQ0003824) with DWQ Aquifer Protection
Section for the removal of residuals from the sludge digesters at the plant. The City owns an 89
acre farm, divided into 10 fields, which is used solely for the application of residuals. The City
transported 628 loads (or 1,852,600 gallons) in 2009.
Please refer to the attached report for specific details from the inspection. If you have any
questions concerning this report, please contact Ms. Graznak or me at [phone].

Subject: permit renewal question
Jenny,
Good afternoon. I'm sending this e-mail to you because I will not be in on Thursday until 4:00 pm and have a two
questions for you regarding the permit renewal form 2A.
In section A.6. on page 3 of the form 2A, it asks for the Maximum Daily Flow Rate. Is this the highest recorded daily rate
for a particular day in a 12 month period [YES] or the average maximum daily flow over a 12 month period [NO]?
Also, in the same section, does the statement "a 12 month period with the 12'h month of this year occurring no more
than three months prior to this application submittal" mean that the 12 month period that I'm reporting results could
be, for example, October 1, 2009 thru September 30, 2010? YES
Thanks.

Subject: Draft NPDES Permit Modification
Permit NCO021211
Graham WWTP
Alamance County
By letter of October 1, the Director notified affected dischargers of the Divisions intent to modify their
NPDES permits to incorporate new requirements under the Jordan Lake Nutrient Management
Strategy and its Wastewater Discharge rule, T15A NCAC 02B .0270. Accordingly, the Division proposes
to modify the subject permit and is enclosing the draft modifications for your review and comment.
At this time, the Division is submitting a notice to the newspaper of general circulation in Alamance
County, inviting public comment on the draft permits for the affected facilities. The notice is scheduled
for publication on or about November 6 and initiates a 30-day comment period.
Please provide any comments you have regarding the draft permit to this office, in writing, no later
than 30 days of receipt of this letter.
The draft permit includes the following changes:
Total Phosphorus (TP) Limit. The total phosphorus limit has been revised to reflect the allocation
allowed under the point source rule. This annual mass limit becomes effective January 1, 2010, at
which time the current concentration limit expires.
Total Nitrogen (TN) Limit. The permit does not include a new limit for total nitrogen at this time.
The rule specifies that nitrogen limits will become effective in 2016, and the Division proposes to
add those limits to affected permits during the 2011 renewal process.
Nitrogen Optimization. The permit includes a new special condition that re -iterates nitrogen
optimization requirements from the point source rule. The rule requires development of an
optimization plan that, upon acceptance by the Division, is to be implemented until the nitrogen
limits become effective in 2016. It also requires annual status reports until 2016 (the final report will
cover calendar year 2015).

Mr. Chris Rollins, City Manager 71
Draft NPDES Permit Modification
November 4, 2009
Some members of the Jordan Partnership undertook a similar effort in 1999. Regardless of its
success at individual facilities, most facilities have seen significant changes in their processes or
operating conditions since then. The Division does not expect any discharger to conduct an
extensive evaluation if it merely repeats the 1999 effort. However, we expect all dischargers to make
a reasonable effort to reduce nitrogen discharges until process improvements are completed, as is
the intent of the rule.
To satisfy this requirement, each discharger should evaluate its treatment facilities and operations
or update its previous evaluation(s) and report its findings and recommendations, including, if
necessary, an update of its current optimization measures. All facilities will be expected to provide
annual reports on the status and effectiveness of the recommended measures.
Additional Special Conditions for Nutrients. The permit includes new conditions that (1) document
the nitrogen and phosphorus allocations assigned to the facility and (2) describe how the mass
limits will be managed in individual permits and in the event that a group compliance association
is formed. These conditions make reference to nitrogen as well as phosphorus and will apply to
each nutrient as the respective limits become effective.
Additional Changes. The special conditions have been re -ordered to put all of the nutrient -related
conditions together for easier reference. The TRC footnote in Condition A.(1.) has been deleted
because the compliance date it specified has passed.
If you have any questions concerning the draft permit, please contact me at [phone] or at
mike. [e-mail].

Permit No. NCO021211
A.(3.) 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 14%.
The permit holder shall perform at a minimum, ua� rterl 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
March, June, September and December. 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 Il 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 TGP313 for the pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3
(original) is to be sent to the following address:
NCDENR/ DWQ/ 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.

Subject: Notification of Intent to Modify NPDES Permit NCO021211
to Incorporate Jordan Lake Nutrient Requirements
Graham WWTP
Alamance County
Governor Bev Perdue recently signed legislation to complete passage of rules for the Jordan Lake
Nutrient Management Strategy. The Strategy includes a Wastewater Discharge rule (T15A NCAC 02B
.0270) that applies to your wastewater treatment facility. Pursuant to Sub -Item (6)(d) of that rule, I am
writing to notify you of (1) the nutrient allocations assigned to your facility and (2) the Division of
Water Quality's intent to modify the facility's NPDES permit to include nutrient limits as provided in
the rule. I also wish to remind you of other provisions of the rule that require your prompt attention.
This letter addresses only certain provisions of the Jordan Lake Wastewater Discharge rule. I encourage
you to familiarize yourself with the remainder of this rule.
Nutrient Allocations. The Wastewater Discharge rule establishes the maximum loads of nitrogen and
phosphorus that can be released from wastewater treatment facilities into the Jordan Lake watershed.
The rule specifies that these wasteload allocations are to be divided among the existing facilities in
proportion to their 2001 permitted flows (with certain exceptions).
Your facility has been assigned nitrogen and phosphorus allocations. The allocations are expressed as
annual mass loadings delivered to the lake. Due to foreseeable losses between the discharge point and
the lake, they are also expressed as the equivalent discharge loads at the point of discharge. The
delivered and the corresponding discharge allocations assigned to your facility are as follows:
NC0021211

Chris Rollins, City Manager
Notification of Intent to Modify NPDES Permit
October 1, 2009
Intent to Modify Permit. The new rule'specifies that facilities with permitted flows at or above 0.1
MGD, including yours, will be subject to effluent limits for nitrogen and phosphorus. The effluent
limits will equal the facility's discharge allocations. The new phosphorus limits become effective
beginning with calendar year 2010. Nitrogen limits become effective beginning with calendar year
2016.
It is the Divisions intent to modify the affected permits by the end of 2009 to include the new
phosphorus limits. We will draft permit modifications for the affected facilities in the coming weeks.
As with any such permit action, the proposed modifications will be subject to public review, and we
will provide you with a copy of the draft permit at that time.
The Division will add nitrogen limits during the 2011 permit renewals, with a compliance date of 2016.
Process Optimization. The rule specifies that no later than six months after its effective date, each
discharger with a permitted flow greater than or equal to 0.5 MGD must "evaluate its treatment
facilities and operations and identify further opportunities to improve and minimize nitrogen
reduction in the existing facilities...; and submit a report to the Division documenting its findings,
proposing optimization measures, and describing expected results."
Please provide three copies of your report to the Division at the following address no later than
February 11, 2010:
Division of Water Quality
Surface Water Protection Section, Point Source Branch
Attn: Jordan Lake Coordinator
1617 Mail Service Center
Raleigh, NC 20699-1617
Each discharger must implement the proposed measures no later than six months after the Division
accepts the report and continue until such time as the facility is upgraded for nitrogen removal. The
affected dischargers must also submit annual progress report to the Division for a period of five years.
If you have any questions regarding these requirements, please contact Mike Templeton at (919) 807-
6402 or at [e-mail].

Description of Collection System and Treatment Process
The City of Graham operates a Public Owned Treatment Works consisting
of a North Carolina Grade II Collection System and a North Carolina Grade IV
Wastewater Treatment Plant.
The collection system operates under a North Carolina Division of Water
Quality Collection System Permit and contains approximately 89 miles of piping
and seven liftstations. The liftstations are named Back Creek No. 1, Back Creek
No.2, Boyd Creek, Cherry Lane, Haw River, Old Fields, and Prytle Drive.
The wastewater treatment facility has a permitted flow of 3.5 million
gallons per day (MGD). This facility consists of bar screens, grit collectors,
primary clarification, extended aeration, final clarifiers, sand filtration,
chlorination, post chlorination basin, de -chlorination, digestion, lime stabilization,
sludge disposal, and laboratory. Effluent is discharged to the Haw River
designated as Nutrient Sensitive Waters (NSW), which is part of the Cape Fear
River Basin.

'erformance
Text Summary of the System Performance for the Period of July 1, 2008 to June
30, 2009.
Collection System: The collection system had a total of 30 sewer calls in
response to blockages, maintenance, and three sanitary sewer overflows two
were reportable to the North Carolina Department of Environment and Natural
Resources, Division of Water Quality. Approximately 15,000 feet of pipe was
chemically treated to prevent root intrusion. Over 10% of the collection system
was inspected with closed circuit television camera and hydraulically cleaned. All
if the City's sewer easements were inspected and mowed twice.
Lift Stations: The City of Graham operates seven lift stations that are
maintained by plant maintenance personnel. During this reporting period the lift
stations had two reportable sewer overflows.
Wastewater Treatment Plant: The Wastewater Treatment Plant No violations of
its NPDES permit. The City's NPDES permit has limits on Flow, Biological
Oxygen Demand, Total Suspended Solids, Ammonia, Dissolved Oxygen, Fecal
Coliform, Chronic Toxicity, and Total Phosphorus. Additional testing is
performed for Total Residual Chlorine, Temperature, Conductivity, Copper,
Mercury, and Zinc. Each month this data is reported to the state thru the
Discharge Monitoring Report (DMR). The City is a member of The Upper Cape
Fear River Basin Dischargers Coalition that performs monitoring upstream and
downstream of our discharge point on the Haw River as well as other locations
on the Haw and Deep Rivers.
Non -Discharge Permit: The City of Graham land applies biosolids to agricultural
land under regulations of the Environmental Protection Agency and the State of
North Carolina. There were No violations.
Violations of permit conditions or other environmental
regulations relating to water quality from the above areas
August 27, 2008. SEWER OVERFLOW, Boyd Creek Lift Station; A reportable
sewer overflow of 12,500 gallons of untreated sewage spilled into "Boyd Creek"
and entered the Cape Fear River Basin. The spill was the result of the abnormal
rainfall associated with remnants of tropical storm Fay.
September 6, 2008. SEWER OVERFLOW, Boyd Creek Lift Station; A
reportable sewer overflow of 1500 gallons of untreated sewage spilled into "Boyd
Creek" and entered the Cape Fear River Basin. The spill was the result of the
abnormal rainfall associated with remnants of tropical storm Hannah.
2

September 25, 2008. SEWER OVERFLOW; A reportable sewer overflow of
1 1,250 gallons of untreated sewage spilled into "County Home Creek" and
entered the Cape Fear River Basin. The spill was the result of root intrusion in
pipe. Blockage was cleared and service was restored.
November 11, 2008. SEWER OVERFLOW; A reportable sewer overflow of
21,000 gallons of untreated sewage spilled into "County Home Creek" and
entered the Cape Fear River Basin." The blockage was the result of vandalism
of a manhole on Sun Drive outfall line.
SUMMARY
During this 12-month period, there were zero NPDES permit violations out
of more than 2,400 sample results.
The City of Graham had only four reportable sanitary sewer overflows of
1000 gallons or more during this reporting period. The total gallons of overflow
were 46,250. Total gallons handled by the system were 507,940,000. Percent
gallons overflowed are 46,250 divided by 507,940,000 x 100%. = less than 0.009
per cent. Therefore, the City of Graham achieved a 99.991 % successful
collection rate of all water discharged into the system.
All sludge was land applied per Land Application Permit regulations with
no permit violations.

Subject: Compliance Evaluation Inspection — NPDES Permit No. NCO021211
City of Graham Wastewater Treatment Plant — Alamance County
Dear Mr. Quick:
Jenny Graznak and Marc Stokes of this office performed a Compliance Evaluation
Inspection at the Graham WWTP in Alamance County on March 25, 2009. David Lawson,
Operator in Responsible Charge (ORC), and Chris Routh (Back -Up ORC) were present for the
inspection. This type of inspection consists of two basic parts: an in -office review of facility files
and self -monitoring data and an on -site inspection of the facility. This particular inspection
evaluated eight (8) areas, and observations from each area are addressed below:
1. Permit
The permit became effective December 1, 2006 and expires May 31, 2011. A complete copy of
the permit was available for review during the inspection.
2. Self -Monitoring Proqram
A review of the self -monitoring data submitted for the period January 2008 through December
2008 showed that all parameters were sampled and analyzed per the requirements of the
permit. There were two violations of the weekly BOD limit and one violation of the monthly
ammonia limit in April 2008. This office previously addressed these violations in a separate
correspondence.
3. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis
by Instrument Specialists, Inc. The flow meter was last calibrated on January 1, 2009, and
verification of calibration was available during the inspection.
4. Facility Site Review
The plant includes grit removal, two primary clarifiers, two extended aeration basins, four
secondary clarifiers, and sludge digesters and storage. Both of the primary clarifiers are being
used at this time. Only one aeration basin is being used. Three of the four secondary clarifiers
are in service. Dechlorination has been added to the treatment system. The site has two
generators. The 800-kW generator (which can operate the entire plant) runs once per month
under full load. Duke Energy does not cut power to the plant during these tests; instead, the
plant staff is responsible for shutting off the main power themselves. The 400-kW generator
runs automatically every two weeks for maintenance purposes but not under load.

5. Operations & Maintenance
Due to several recent staff illnesses, the plant has been short-staffed and operation duties have
been switched around quite a bit during the last month. Perhaps for this reason, the plant did
not appear as well maintained as in the past. There was evidence of sludge in the secondary
clarifier troughs on the day of the inspection. Floating solids and trash were noted in the
chlorine contact chamber. The dumpster that catches the bar screenings had some litter
around it. Please verify that the small drain beside the dumpster is directed back to the
influent and not to the Stormwater drain system.
Scott Jennings is the Maintenance Supervisor. The plant operates a preventative maintenance
computer program. The maintenance staff issues work orders once per month and more
frequently for repairs, etc. A SCADA system is used to monitor and control some operations at
the plant, including pump stations.
6. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream
monitoring requirements have been waived as long as the City of Graham remains a member of
the Upper Cape Fear River Basin Association.
7. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection.
8. Laboratory
Meritech, Inc. analyzes BOD, metals, total nitrogen, and mercury for the plant. The facility's on -
site laboratory provides analysis for all other parameters. The lab coordinator is Shelby Smith.
Flow -proportional samples are collected by ISCO samplers.
Our office wishes speedy recoveries for both Mr. Quick and Mr. Lawson. Please refer to
the attached report for specific details from the inspection. If you have any questions
concerning this report, please contact Mrs. Graznak or me at [phone].

Dear Ms. Grazak:
The Compliance Evaluation Inspection letter dated March 27, 2009 had
several comments that need to be addressed. The first one is the housekeeping
impressions, all the factors listed in the report are correct. We have made
changes to help keep our general appearance in top form again. The Effluent
Clarifier is normally skimmed each weekday. However, on the inspection day it
had not been done.
The small drain in question near the dumpster is piped to the manhole —
immediately before the influent structure. We added trace dye and verified the
drainage flow to that manhole. Also, there is a small drainage for the grit
dumpster that also goes to the same manhole; again it was also trace dyed and
verified.
The City appreciates vast number of positive comments in the inspection.

If, additional information is required, please let me know. I can be reached
at 336.570.6721.
Sincerely,

Subject: Compliance Evaluation Inspection — NPDES Permit No. NCO021211
City of Graham Wastewater Treatment Plant — Alamance County
Dear Mr. Quick:
Jenny Graznak of this office - performed a Compliance Evaluation Inspection at the
Graham WWTP in Alamance County on January 24, 2008. David Lawson, Operator in
Responsible Charge (ORC), was present for the inspection. This type of inspection consists of
two basic parts: an in -office review of facility files and self -monitoring data and an on -site
inspection of the facility. This particular inspection evaluated eight (8) areas, and observations
from each area are addressed below:
1. Permit
The permit became effective December 1, 2006 and expires May 31, 2011.
2. Self -Monitoring Program
A review of the self -monitoring data submitted for the period November 2007 through October
2007 showed that all parameters were sampled and analyzed per the requirements of the
permit.
3. Flow Measurement
Influent flow is measured with an ultrasonic flow meter, which is calibrated on a quarterly basis
by Instrument Specialists, Inc. The meter was last calibrated on January 1, 2008, and
verification of calibration was available during the inspection.
4. Facility Site Review
The plant includes grit removal, two primary clarifiers, two extended aeration basins, four
secondary clarifiers, and sludge digesters and storage. Only one of the two primary clarifiers is
used at a time. Three of the four secondary clarifiers are in service. Secondary clarifiers looked
clean and well maintained on the day of the inspection. Little to no floating solids were noted.
The site has two generators. The 800-kW generator runs once per month under full load,
contracted through Duke Power. The 400-kW generator runs automatically every two weeks for
maintenance purposes but not under load.
5. Operations & Maintenance
The City's application to DWQ for Authorization to Construct Dechlorination equipment on -site
has been approved. Construction is set to begin soon to meet the new Chlorine limit that will
take effect on July 1, 2008. At the end of November 2007, the City replaced alum with a
chemical feed called PAX-18 to remove phosphorus. According to operators, it has been
working well. One of the aeration basins has been taken out of service due to lower flows. The
plant operates a preventative maintenance program. The maintenance staff issues work orders

once per month and more frequently for repairs, etc. Scott Jennings is the Maintenance
Supervisor. A SCADA system is used to monitor and control some operations at the plant,
including pump stations.
6. Effluent/Receiving Waters
The effluent is discharged into the Haw River in the Cape Fear River Basin. In -stream
monitoring requirements have been waived as long as the City of Graham remains a member of
the Upper Cape Fear River Basin Association.
7. Records/Reports
The DMRs, files, and lab data are maintained according to the permit. A copy of this data was
available for review during the inspection.
8. Laboratory
Meritech, Inc. analyzes BOD, metals, total nitrogen, and mercury for the plant. The facility's on -
site laboratory provides analysis for all other parameters. The lab coordinator is Shelby Smith.
Flow -proportional samples are collected by ISCO samplers.
An inspection of the facility's Stormwater permit No. NCG110021 was also conducted on
the same day. The plant has five Stormwater outfalls, which are all labeled with signs. The
10,000-gallon alum tank now holds PAX-18 and is protected with secondary containment.
Diesel fuel is stored in a double -walled tank. The Stormwater Pollution Prevention Plan is
complete and was available for review during the inspection. Scott Jennings performs semi-
annual visual observations at the outfalls; the last event was October 10, 2007. Stormwater
training occurs at the plant on an annual basis and is documented in the Stormwater Pollution
Prevention Plan.
The facility was found to be in compliance with both permits. Our office appreciates the
efforts made by City of Graham to meet permit requirements. Please refer to the attached
report for specific details from the inspection. If you have any questions concerning this report,
please contact Mrs. Graznak or me at [phone].

Steve W. Tedder

Inspection Summary:
Reason for Visit: Routine
An inspection of the facility's Stormwater permit No. NCG110021 was also conducted on the same day. The plant has
five Stormwater outfalls, which are all labeled with signs. The 10,000-gallon alum tank now holds PAX-18 and is
protected with secondary containment. Diesel fuel is stored in a double -walled tank. The Stormwater Pollution
Prevention Plan is complete and was available for review during the inspection. Scott Jennings performs semi-annual
visual observations at the outfalls; the last event was October 10, 2007. Stormwater training occurs at the plant on an
annual basis and is documented in the Stormwater Pollution Prevention Plan.

Description of Collection System and Treatment Process
The City of Graham operates a Public Owned Treatment Works consisting
of a North Carolina Grade it Collection System and a North Carolina Grade IV
Wastewater Treatment Plant.
The collection system operates under a North Carolina Division of Water
Quality Collection System Permit and contains approximately 89 miles of piping
and seven liftstations. The liftstations are named Back Creek No. 1, Back Creek
No.2, Boyd Creek, Cherry Lane, Haw River, Old Field, and Prytle Drive.
The wastewater treatment facility has a permitted flow of 3.5 million
gallons per day (MGD). This facility consists of bar screens, grit collectors,
primary clarification, extended aeration, final clarifiers, sand filtration,
chlorination, de -chlorination, post chlorination basin, digestion, lime stabilization,
sludge disposal, and laboratory. Effluent is discharged to the Haw River
designated as Nutrient Sensitive Waters (NSW), which is part of the Cape Fear
River Basin.

ppppppp,
Performance
Text Summary of the System Performance for the Period of July 1, 2007 to June
30, 2008.
Collection System: The collection system had a total of 30 sewer calls in
response to blockages, and sanitary sewer overflows —one was reportable to the
North Carolina Department of Environment and Natural Resources, Division of
Water Quality. The City inspected over 10 % of the system and cleaned 53,140
feet of sewer mains.
Lift Stations: The City of Graham operates seven lift stations that are
maintained by plant maintenance personnel. During this reporting period the lift
stations had No sewer overflows.
Wastewater Treatment Plant: The Wastewater Treatment Plant had four
violations of its NPDES permit. The City's NPDES permit has limits on Flow,
Biological Oxygen Demand, Total Suspended Solids, Ammonia, Dissolved
Oxygen, Fecal Coliform, Chronic Toxicity, and Total Phosphorus. Additional
testing is performed for Total Residual Chlorine, Temperature, Conductivity,
Copper, Mercury, and Zinc. Each month this data is reported to the state thru the
Discharge Monitoring Report (DMR). The City is a member of The Upper Cape
Fear River Basin Dischargers Coalition that performs monitoring upstream and
downstream of our discharge point on the Haw River as well as other locations
on the Haw and Deep Rivers.
Non -Discharge Permit: The City of Graham land applies biosolids to agricultural
land under regulations of the Environmental Protection Agency and the State of
North Carolina. There were No violations during this reporting period.
Violations of permit conditions or other environmental
regulations relating to water quality from the above areas
July 9, 2007. SEWER OVERFLOW; A reportable sewer overflow of 1,800
gallons of untreated sewage occurred at a manhole adjacent to "Still House
Branch" and entered the Cape Fear River Basin. The spill was the result of root
intrusion in the sewer main. Repairs were made and service restored.
September, 2007. NPDES PERMIT; The Wastewater Plant had a permit
violation of quarterly Total Phosphorus. The limit is a quarterly average of 2.0
milligrams per liter (mg/L) of effluent. The City's average for the period of July,
August, and September, 2007 was 2.19 mg/L. All plant operational attempts to
reduce phosphorus did not bring the average into compliance.
April, 2008. NPDES PERMIT; The Wastewater Plant had three permit violations
which were caused by "Upset Plant Conditions" due to heavy rains at the
beginning and end of the month. Two of the violations were Biochemical Oxygen
2

PPPPPPF'
Demand weekly limits. Our averages for the two weeks were 20.2 mg/L and 18.9
mg/L. Our weekly NPDES permit limit for B.O.D. is 18.0 mg/L. The other
NPDES permit violation was for the monthly limit for Ammonia. The monthly limit
is 4.0 mg/L. The City's average Ammonia was 5.02 mg/L. The wastewater plant
removes ammonia from the effluent by nitrifying bacteria. When our facility
experiences "Upset Plant Conditions, "it takes approximately 3 three weeks to
regain enough of the bacteria to treat incoming ammonia to the facility.
SUMMARY
During this 12-month period, there were four NPDES permit violations- out
of more than 2,400 sample results.
The City of Graham had only one reportable sanitary sewer overflow of
1000 gallons or more during this reporting period. The total gallons of overflow
were 1,800. Total gallons handled by the system were 479,800,000. Percent
gallons overflowed are 1,800 divided by 479,800,000 x 100% = less than 0.0002
per cent. Therefore, the City of Graham achieved a 99.999 % successful
collection rate of all water discharged into the system.
All sludge was land applied per Land Application Permit regulations with
no permit violations.
Notification
A Public Notice was placed in a local newspaper informing the public that
a copy of this report can be obtained at the City of Graham, City Hall located at
201 South Main Street, Graham, NC. Additionally, this report is also, available
on the Internet at http://www.cityofgraham.com/
I certify under penalty of law that this report is complete and accurate to the best
of my knowledge. I further certify that this report has been made available to the
users or customers of the named system and that those users have been notified
of its availability.

Hi Jenny,
On Friday, April 25, 2008, I reported to Jennifer Carter, WSRO, that the City's WWTP
had (2) weekly permit violations for B.O.D. Our weekly limit for BOD is 18 mg/L. Week
ending on 4/4/2008 was 20.2 mg/L. Week ending on 4/11/2008 was 18.9 mg/L. The next
week was 5.6 mg/L. I anticipate we will meet the monthly average limit. The high BODs
were caused by a rain total of 3.42" for the period of March 29th thru April 6th, 2008. Our
plant had been setup for the lower flows from last summer. We opened an additional
aeration basin on April 10, 2008, and effluent numbers began improving within a few days.
Ms. Carter told that there was no need to report this info to the regional office just
note this on the DMR. However, this seems to be a departure from the past. As our normal
plant inspector, I thought you should be aware of this BOD situation.
I'll be on vacation from 4/28 thru 5/5, call Victor Quick if you have any questions.
Thanks!
David Lawson

As determined by a plant visit and subsequent correspondence with plant staff, the
abovementioned violations seem to be the result of a major system upset that occurred at the City of
Graham WWTP in late September/early October. Staff at the plant think the condition was caused by an
illegal dumping from a wastewater contributor. You should continue to be vigilant to such incidents
occurring at your facility.
Please be aware that violations of your NPDES permit could subject you to enforcement action by
this Division with the possible assessment of civil penalties of up to $25,000 per day per violation. Should
you have any questions, please contact Jenny Freeman or me at [phone].

SUMMARY
The City of Graham operates a 3.5 MGD wastewater treatment facility consisting of a
mechanical bar screen, grit chamber, primary settling tanks, extended aeration basin, final
clarifiers, aerobic digester, sand filter, chlorination, and post aeration.
Pre -Treatment — The town has an approved pre-treatment program. The program covers 3 non -
categorical SIUs and 2 CIUs. The permit requires the town to continue to operate its approved
pre-treatment program.
Basin Plan — This segment of the Haw River is supporting aquatic life because of a Good -Fair
benthic community rating, however the turbidity standard was exceeded 7 % at one sampling site
and 10 % at another.
Reasonable Potential Analysis — A reasonable potential analysis was done for cadmium,
chromium, copper, cyanide, lead, mercury, molybdenum, nickel, and zinc. Copper, lead and zinc
showed reasonable potential to exceed water quality standards. A limit of 34 µg/L will be
implemented for lead. Zinc and copper are action level standard parameters, so no limit will be
implemented.
Compliance review — In 2005 the facility had several violations of weekly averages for BOD,
Total Suspended Solids, Fecal Coliform and ammonia.
Fact Sheet
NPDES NCO02121 1

SUMMARY OF PROPOSED CHANGES
• Total chlorine limit — A limit of 28 µg/L was added to the permit based on the water
quality standard with a schedule of compliance of 18 months after issuance of the permit.
• Ammonia weekly average limit — A weekly average limit of 12 mg/L for the summer and
24 mg/L for the winter season were added to the permit. According to federal rules
permits should include both weekly average and daily maximum limits.
• Lead daily maximum limit - A limit of 34 µg/L was added to the permit based on the
reasonable potential analysis.
• Priority Pollutant Analysis — A special condition to analyze for priority pollutants was
added to the permit. This condition is been added to all municipal facilities above 1 MGD
to collect data necessary for permit renewal.
PROPOSED SCHEDULE FOR PERMIT ISSUANCE
Draft Permit to Public Notice: March 15, 2006
Permit Scheduled to Issue: June 1, 2006

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
The City of Graham has requested renewal of the Graham WWTP permit. The 3.5-MGD WWTP
discharges into Haw River, a class C NSW stream, in CPF02 subbasin.
The Haw River is listed on North Carolina's 2000 303(d) list. The segment from NC Highway
87 to NC Highway 49 is listed as partially supporting its uses. The causes of impairment is
fecal coliform, turbidity, and biological impairment (sediment) for a 19.2 mile stretch, with
potential sources of agriculture, storm sewers and urban runoff. DWQ will develop a TMDL for
fecal coliformlthis segment and a management strategy for turbidity. However, the Graham
WWTP discharges into the Haw River below this 303d listed segment.
The 1998 biological rating for Haw River at NC 54 near Graham is Good -Fair. This segment
was also rated Good -Fair in 1993 and 1989, which was an improvement from the Fair rating in
August 1987. Haw River from NC 49 to a point 0.4 miles dwnstrm of Cane Creek (South side of
Haw River) has a use support rating of fully supporting. Problem parameters are turbidity with
the major source being nonpoint. The chemical rating from 94-98 is partially supporting. The
benthos rating is Good at Highway 54; at SR1005, the rating is Good -Fair.
Graham currently has an active pretreatment program with Long Term Monitoring Program.
There are six significant industrial users discharging to the system. The facility has an average
industrial flow of 0.633MGD (per 1996 headworks analysis). The permitted industrial flow is
0.7168 MGD.
SIUs - for Graham WWTP are as follows:
• BFI Medical Waste, Inc. - incineration of solid medical waste - 0.017 MGD - intermittent
flow
• Culp Weaving - woven fabric - 0.305 MGD- intermittent flow
• Uni-Chem Hose Corp. - rubber & plastics hose - 0.015 MGD- intermittent flow
• Luxfer Gas Cylinders - aluminum gas cylinders - 0.057 MGD - intermittent now
• Nannoflex - narrow elastic - 0.020 MGD - intermittent flow
• G & K Services- industrial laundry - 0.072 MGD - intermittent flow

Graham is currently in the idle of construction for plant impro-, nt.. No hydraulic _
expansion is involved. ATC issued in 1994 for upgrade of existing digestors with new pumps
and blowers, the construction of sludge stabilization/mixing tanks, and new sludge loading w*Z. 5�n
storage.
Facility submitted letter on June 8, 2000, reporting on the progress the Town's efforts to
address compliance with the Nitrogen Discharge Limits proposed for the Haw River in the CPF
basin. The city has addressed nutrient removal by 1) redesigning the alum feed facilities to
allow continual treatment for P removal. 2) proposed improvements to the sludge digestion and
storage capabilities to allow regular sludge wasting, Additional final settling tanks will be half
the current rate. Evaluation of methods to reduce the discharge from the Graham plant,
included a review of land application. Also standby generators and upgrading a pump station,
improve reliability and reduce the possibility of untreated discharge.
In Sept. 1997, orthophosphate sampling requirement was deleted from the Graham permit
because of Memorandum of Understanding with the City of Burlington.
In July 1997, mercury limit was removed and twice per month monitoring was included.

Checked with Aquatic Tox on any reported basis for fails. There was no info in AQ TOX
suspense files.
COMPLIANCE SUMMARY:
Facility's compliance record since 1998 has been marked by exceedances in TSS and TP. The
improvements that are currently under construction should help with meeting these limits.
Graham has passed all compliance evaluation inspections.
For January 2001, Qw = 1.64 MGD (approximately 46% of capacity), BOD5=1.67 mg/l,
NH3=1.68 mg/1, TSS=17.9 mg/1, TN=27.6 mg/ and TP=1.15 mg/1.

INSTREAM MONITORING:
Graham is a participant in the Upper Cape Fear River Basin Association and the coordinated
instream monitoring effort. Individual instream monitoring requirements for DO, temperature,
conductivity, and fecal coliform have been waived from the Graham permit effective April 6,
2000. A review of instream monitoring data prior to April 2000 - In April - October 1998 and
1999, instream data looked good most months, monthly instream DO averaged above 5 mg/l.
Only one upstream and one downstream value reported below 5 mg/1 (August 1999). Will
recommend continuation of waiver of instream monitoring for dissolved oxygen and
temperature while Graham is a member of the Upper Cape Fear River Basin Association.
PROPOSED CHANGES:
The following modifications have been made to the permit:
Addition of effluent limitation for cyanide. RPA was based on values from 1999 -
2000 Long Term Monitoring Plan data. (Will recommend that facility report LTMP
data on DMRs submitted to the Division.) Analysis indicated that cyanide should be
limited based on a predicted value that would exceed the allowable concentration.
Highest data value was 157 ug/1 in March 1999. The EPA V2 FAV criteria value of 22
ug/l will be assigned as a limit per Division policy limits and monitoring for CN and
metals (4/28/99)

Dear Mr. Quick:
The Division has reviewed your NPDES permit application for the Graham WWTP and has drafted
a NPDES permit for the facility.
The draft permit authorizes The City of Graham to discharge up to 3.5 MGD of treated wastewater
from the Graham WWTP to the Haw River, a class C NSW water in the Cape Fear River Basin. The permit
includes discharge limitations for flow, biochemical oxygen demand (BOD), total suspended solids (TSS),
ammonia, dissolved oxygen, fecal coliform bacteria, pH, total phosphorus, cyanide and chronic toxicity.
The following modification have been made to the permit:
• An effluent limitation for cyanide of 22 ug/I has been added to the permit based on evaluation of
the reasonable potential analysis and Long Term Monitoring Plan.
• Instream fecal coliform monitoring has been discontinued based on revised DWQ procedure.
Graham is a participant in the Upper Cape Fear River Basin Association and is a part of the
environmental monitoring plan. Individual instream monitoring has been waived from the
NPDES permit. In the event that Graham should leave the Association, instream monitoring for
dissolved oxygen, conductivity and temperature will be reinstated.
Per North Carolina regulation 15A NCAC 2B .0506(b)(3)(J), the results of all tests on the
characteristics of the effluent, including but not limited to NPDES Permit Monitoring Requirements, shall be
reported on monthly report forms. All future effluent metals data submitted for Graham's Pretreatment
Long Term Monitoring Plan should be reported on the Discharge Monitoring Reports (DEM Form MR-1).
Please note that this facility discharges to nutrient sensitive water (NSW) and may already have
total phosphorus limits as a result of the NSW strategy. In 1997 the Clean Water Responsibility Act (House
Bill 515) was enacted, with the intent to strengthen the control of nutrients from all discharges to NSW
waters. Facilities permitted to discharge > 500,000 gallons per day, and any new or expanding facilities, will
be subject to nutrient limitations for total nitrogen and total phosphorus according to House Bill 515
requirements. The nutrient limitations are effective January 1, 2003, unless a compliance extension was
received and approved by the Division. If an extension was not received/approved, the nutrient limits appear

in this permit. If an extension was approved, the nutrient limits will be deferred until results of the nutrient
response modeling effort are completed. Please note that modeling results may result in limits lower than
those mandated by House Bill 515.
Please review the draft permit carefully and provide any comments you wish to submit to this
office by May 11, 2001.

SUPPLEMENT TO EFFLUENT LIMITATIONS
AND MONITORING REQUIREMENTS
SPECIAL CONDITIONS
A. (2) PROVISIONAL WAIVER OF INSTREAM MONITORING REQUIREMENTS
Instream monitoring requirements in this NPDES permit shall be provisionally waived so long as
the Permittee remains a member of the Upper Cape Fear River Basin Association and the
Association continues to function as approved by the Division and Environmental Management
Commission. If the Permittee does not participate in the Association or if the Association ceases
to function, the instream monitoring requirements in this permit become effective immediately;
and the Division may reopen this permit by administrative letter to establish additional instream
monitoring requirements it deems necessary to adequately characterize the effects of the
discharges on water quality in the receiving stream.
A (3). 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 14 %.
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
March, June, September, and December. 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: Environmental Sciences Branch
North Carolina Division of
Water Quality
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 (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 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.

Subject: Implementation of Upper Cape Fear River Basin Association
NPDES Permit Modification for Instream Sampling
Permit NCO021211 Graham. City - WWTP
Alamance County
As a participant in the coordinated instream monitoring efforts within the Cape Fear River basin, your facility
entered into an agreement with the North Carolina Department of Environment and Natural Resources (NC
DENR) that provides both parties with an effective environmental monitoring tool. By this letter, NC DENR is
waiving the instream monitoring requirements specified within the subject permit as of April 6, 2000. The
Memorandum of Agreement (MOA) signed by NC DENR and you (or your representative) identifies the revised
stations, parametric coverage and frequency of analysis required for your facility.
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 dated
December 6, 1983 (and as subsequently amended). Should your membership in the MOA be terminated, the
instream monitoring requirements specified in the subject permit will be reinstated. You shall notify the Division
immediately upon termination of membership.
I would like to express my gratitude for the cooperation of all participants in this innovative approach to
environmental monitoring. It is expected that the results of the agreement will effectively contribute to our
understanding of the Cape Fear River Basin ecosystem. We have designated Zi-Qiang Chen as our primary
contact for issues related to the MOA. He can be reached at [phone].
We also look forward to the advances that this cooperative agreement will provide in our management of the
Cape Fear River Basin. We encourage you to contact us should any questions arise regarding the monitoring
efforts or interpretations of the information collected. We will maintain our own series of monitoring stations in
the basin which (when added to the data collected under this MOA) will greatly expand our knowledge of this
ecosystem. We thank you again for your participation and look forward to a successful monitoring effort.
Since
err T. Stevens
