Permit No. NC0020401
Hickory - Northeast WWTP
Facility Class IV
Catawba County
Dear Mr. Berry:
Division personnel have reviewed and approved your application for renewal of
the subject permit. Accordingly, we are forwarding the attached NPDES discharge
permit. This permit is issued pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and
the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended).
The fuial permit authorizes the City of Hickory to discharge municipal
wastewater from the Northeast Wastewater Treatment Plant to the Catawba River
(Lake Hickory), a class WS-V and B water in the Catawba River Basin. The permit
includes discharge limitations/or monitoring for flow, GODS, ammonia nitrogen,
total residual 'chlorine, fecal coliform, cyanide, copper, silver, chronic toxicity and
several other parameters.
Please note that the monthly average and daily maximum limits for total
mercury have been removed from the permit based on approval of the statewide
mercury TMDL plan and evaluation of submitted effluent mercury data. Mercury will
be monitored annually in the effluent pollutant scans and a special condition
regarding completion of a mercury minimization plan has been added to the permit.

There have been some changes in condition A.4. Effluent Pollutant Scan: 1)
language has been updated to note that three scans must be completed during the
permit cycle, and 2) mercury must be sampled using EPA Method 1631 E. •
The following modifications to the draft permit remain in the final permit:
• The following procedure has been implemented by DWQ: Total residual
chlorine (TRC) compliance level changed to 50 ug/1. Effective March 1,
2008, the Division received EPA approval to allow a 50 ug/1 TRC compliance
level. This change is due to analytical difficulties with TRC measurements.
Facilities will still be .required to report actual results on their monthly
discharge monitoring report (DMR) submittals, but for compliance purposes,
all TRC values below 50 ug/1 will be treated as zero. A footnote regarding
this change has been added to the effluent limitations page in the permit.
• The cyanide limit has been modified from the daily maximum of 22 ug/1 based
on revised Division guidance for the calculation of acute limits. Based on the
results of the reasonable' potential analysis, the new cyanide limits are a
monthly average limit of 37 and a daily maximum of 138 ug/1.
• Twice per month monitoring for copper, silver and zinc will be modified to
quarterly monitoring based on the results of reasonable potential analyses and
revised Division guidance.
• Limits and monitoring for arsenic, chromium, nickel and total phenolic
compounds will be deleted from the permit based .on the results of the
reasonable potential analysis. These parameters will be monitored in the
pretreatment long term monitoring plan.
• Special condition A(3) for total residual chlorine limit effective date has been
removed from this permit. The chlorination/dechlorination system has been
installed.
If any parts, measurement frequencies or sampling requirements contained in
this permit are unacceptable to you, you have the right to an adjudicatory hearing
upon written request within thirty (30) days following receipt of this letter. This
request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings,
6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a
demand is made, this permit shall be final and binding.
Please take notice that this permit is not transferable. The Division may require
modification or revocation and reissuance of the permit. This permit does not affect
the legal requirements to obtain other permits, which may be required by the Division
of Water Quality, or permits required by the Division of Land Resources, Coastal Area
Management Act, or any other Federal or Local governmental permits may be
required.

Permit Number NC0020401
A. (2.) CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 13%.
The permit holder shall perform at a minimum, civarterlq 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
January, April, July and October. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit, then multiple -concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the
highest concentration having no detectable impairment of reproduction or survival and the lowest
concentration that does have a detectable impairment of reproduction .or survival. The definition of
"detectable impairment," collection methods, exposure regimes, and further statistical methods are
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. If reporting pass/fail
results using the parameter code TGP3B, DWQ Form AT-1 (original) is sent to the below address. If
reporting Chronic Value results using the parameter code THP3B, DWQ Form AT-3 (original) is to be
sent to the following address:
Attention: North Carolina Division of Water Quality/Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate
signature. Total residual chlorine of the effluent toxicity sample must be measured and reported if
chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is
required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test
form indicating the facility name, permit number, pipe number, county, and the month/year of the
report with the notation of "No Flow" in the comment area of the form. The report shall be submitted
to the Environmental Sciences Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required,
monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.
If the Permittee monitors any.pollutant more frequently then required by this permit, the results of
such monitoring shall be included in the calculation & reporting of the data submitted on the DMR &
all AT Forms submitted.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control
organism survival, minimum control organism reproduction, and appropriate environmental controls,
shall constitute an invalid test and will require immediate follow-up testing to be completed no later
than the last day of the month following the month of the initial monitoring.

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and (j) and 15A NCAC 02H .0903(b)(11)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903(b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SIU); or
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 11/09/2011

NPDES Permit Standard Conditions

Version 11/09/2011

AMENDMENTS TO THE FACTSHEET AND PERMIT
12/28/2012 Comments were received from the Hickory on the draft for the Northeast
WWTP on September 2, 2011.
1) Facility wanted the issuance of the permit delayed until upgrades were completed on
the plant. Hickory indicated that upgrades would be completed by end of 2011-
DWQ response - this permit was held for more than a year while statewide issues with
mercury were resolved. A review of files found an ATC for plant upgrades was issued in
2010 however no engineer's certification has been completed and sent to the Division to
date. DWQ will issue permit now and make modifications when signed and sealed
engineer's certification is received that indicates upgrades are completed.
2) Facility had concerns with the assignment of mercury limits in the draft permit.
Requested removal of Hg limit or a higher limit and were agreeable to a mercury
mitigation plan.
DWQ response - Effective October 2012, NC statewide mercury TMDL and
NPDES permit implementation plan was approved by EPA. Based on new
mercury evaluation tool for effluent dischargers, a mercury limit is no longer
required for the Hickory- Northeast facility. Mercury monitoring will be
submitted in the annual pollutant scans. A special condition for a mercury
minimization plan will be included in the permit.
3) Requested changes/edits to the permit boilerplate
DWQ response - Changes to the boilerplate (NPDES Standard permit conditions) have
been approved effective November 2011 and modified boilerplates are available for
review online and are being mailed with all DWQ discharge permits.

Summary
The City of Hickory is requesting renewal of the NPDES permit for the Northeast
WWTP. The 6.0 MGD wastewater treatment plant discharges into the Catawba River
(Lake Hickory). The plant currently serves approximately 20,260 persons. The
existing permit has secondary limits for BOD5 and TSS, fecal coliform and TRC limits
in addition to limits and monitoring requirements for arsenic, chromium, cyanide,
nickel, phenols, copper, silver, zinc and other parameters. The treatment plant has a
Pretreatment Program and a Long Term Monitoring Plan as it receives flow from the
following Significant Industrial Users (SIUs) (see Table 1). The facility should
continue to implement the Pretreatment Program in the next permitting cycle.

Wastewater generated is treated using an extended aeration plant consisting of the
following treatment units:
• Influent sampler
• Parshall flume
• Dual influent bar screens
• Grit chamber
• Four rectangular and one circular primary clarifiers
• Eight aeration basins (total volume - 2,000,000 gallon)
• Two circular secondary clarifiers •
• Chlorine disinfection
• Dechlorination
• Post aeration
Current Stream Conditions
The receiving stream is the Catawba River (Lake Hickory). The receiving stream at the
discharge point is classified WS-V and B water in the Catawba River Basin. Lake
Hickory is a run -of river impoundment located between Lake Rhodhiss and Lookout
Shoals Lake on the Catawba River. Lake Hickory is not listed on North Carolina's
2010 303d impaired streams list.
Note: Since the Federal Energy Regulatory Commission (FERC) license for the
Catawba River dams has not been renewed and updated minimum releases are not
final, the estimated s7Q 10 flow of 60 cfs is based on the historical minimum release of
40 cfs from the dam below Lake Rhodhiss and estimated flows of -20 cfs at the
mouths of Gunpowder Creek and Little River.
Instream Monitoring
The current permit requires the facility to monitor dissolved oxygen, fecal coliform,
temperature, and conductivity upstream and downstream of the discharge point.
Instream data was reviewed for 2008 through 2010 for the critical months of June,
July and August. The facility samples three times per week during these months.
Monthly averages for dissolved oxygen and fecal coliform showed no exceedances of
the water quality standards. There were some daily exceedances of fecal coliform
both upstream and downstream of the Hickory plant. There were only two instances
1 lickorv- Northeast \V11. P Fact Sheet
NPDES Renewal
Page 2

of DO slightly less than 5 mg/1 (4.8 mg/1 and 4.9 mg/1, June 2008, upstream of the
facility) in the three years reviewed.
There are no proposed changes for the in -stream sampling requirements.
The LTMP requires yearly upstream monitoring of metals in July. This data was
reviewed for 2008, 2009, 2010. Most metals were below detection however there were
hits for:
• lead (0.3 ug/1, 0.15 ug/1, 0.11 ug/1) in all three years . These values were well
below the NC standard of 25 ug/1);
• cyanide hits of 9 ug/1 and 7 ug/1 in 2008 and 2009, exceeded the NC standard
of 5 ug/1, however CN was below detection in 2010;
• toluene of 3.9 ug/1 in 2008, toluene was below detection in 2009 and 2010 (NC
standard = 11 ug/1).
Compliance Summary
Overall, facility's compliance with permitted limits appears satisfactory. Permit
violations and actions taken are noted below:
NOVs for cyanide violations in Nov. and Dec. 2006, Jan. 2007
Enforcement cases for total phenols in March and April, 2008
Enforcement cases for BOD and fecal coliform in March 2010
Enforcement case for TSS in May, 2010
Enforcement case for BOD in March 2011
Most recent compliance evaluation inspection by the Mooresville Regional Office
conducted 10 / 7 / 2010. Facility was rated noncompliant, however there were several
construction projects in progress at the time, equipment that was deteriorating was
on schedule to be replaced.
Toxicity Testing
Current Refluirement: Chronic Toxicity (Ceriodaphnia) P/F at 13%, Testing conducted
during the months of January, April, July, and October.
The facility has consistently passed all quarterly chronic toxicity tests since 2006.
Recommendation: Renewal of Chronic Toxicity (Ceriodaphnia) P/F at 13%, Jan,
April, July; Oct.
Reasonable Potential Analysis (RPA)
Data for the following parameters was reported in the discharge monitoring reports or
priority pollutant analyses and a RPA was done: arsenic, cadmium, chlorinated
phenolic compounds, chromium, copper, cyanide, lead, mercury, nickel, total
phenolic compounds, silver, selenium, toluene, and zinc.
Reasonable' potential analysis was conducted based on data from January 2009
through March 2011. Results and data analysis are attached.
• Limits for arsenic, chromium, nickel and total phenols will be removed
fror it the permit based on results of the reasonable potential analysis
which indicated no reasonable potential to exceed the water quality standard.
Monitoring for these parameters will still be required in the LTMP.

• Quarterly monitoring for the copper, silver, and zinc will be included in
the permit based on the reasonable potential analysis results which
indicated the potential to exceed the action level standard. Current Division
procedure recommends quarterly monitoring coinciding with the chronic
toxicity test.
• Cyanide results indicate the reasonable potential to exceed the allowable
concentration. Based on current Division procedure, a monthly average
limit of 37 ug/1 and daily maximum limit of 138 ug/1 for cyanide will be
included in the permit.
• Chlorinated phenolic compounds were reviewed in the annual priority
pollutant analysis and although results indicate reasonable potential to exceed
the allowable concentration, all reported data values were below detection.
Based on Division procedure, no limit or monitoring will be required in the
permit.
• Mercury data was evaluated and results indicated the reasonable potential
to exceed the water quality standard instream. EPA currently
recommends that because of North Carolina's statewide stream
impairment for mercury, there be no dilution allowed in calculation of
mercury limits. Therefore, the standard of 12 ng/1 must be met at the end
of the effluent pipe. Recommended limits are monthly average limit of
12 ng/1 and daily maximum limit of 36 ng/1.
Proposed Changes
The following modifications are recommended for the renewal of the permit:
• The existing cyanide limit has been modified from the daily maximum of 22
ug/1. The new cyanide limits based on reasonable potential are a monthly
average limit of 37 and a daily maximum of 138 ug/1. The new daily maximum
limit is based Division guidance recommending the application of the 1 Q 10
flow in calculating the limit) .
• A monthly average mercury limit of 12 ng/1 and a daily maximum mercury limit
of 36 ng/1 are added to the permit based on results of the reasonable potential
analysis. Per EPA recommendation, there is no dilution allowed in the
calculation of mercury limits due to the statewide impairment of all streams for
mercury. Therefore the state standard of 12 ng/1 for mercury must be met at
the end of pipe for all dischargers that show reasonable potential.
• Twice per month monitoring for copper, silver and zinc will be reduced to
quarterly monitoring based on the results of reasonable potential analyses and
revised Division guidance.
• Limits for arsenic, chromium, nickel and total phenolic compounds will be
removed from the permit based on the results of the reasonable potential
analysis. These parameters will be monitored in the pretreatment long term
monitoring plan.
• Special condition A(3) for total residual chlorine limit effective date has been
removed from this permit. A chlorination/dechlorination system has been
installed.
• TRC compliance language/footnote has been added to the effluent page.

RE: Draft NPDES Permit (No. NC0020401) Hickory — Northeast WWTP
Dear Ms. Nowell;
City of Hickory
Public Utilities Administration
Post Office Box 398
Hickory, NC 28603-0398
Telephone [phone]
Fax [phone]
The purpose of this correspondence is to provide comments related to the proposed Draft Permit for the
City of Hickory Northeast WWTP (NC 0020401). The City of Hickory received a copy of the Draft permit
for review on July 27, 2011 and our intent is to provide comments for consideration by the August 26,
2011 date specified in the cover letter. The particular items of concern for the City of Hickory are that the
Treatment Unit descriptions will change in the very near future since we are currently in the process of
upgrading the Facility, the proposed Mercury numeric limit and we would like to incorporate the work of
the NC Water Quality Association in the Boiler plate language in the Draft permit.
The Northeast WWTP is currently under going an upgrade to change the facility treatment process to an
Oxidation Ditch process and completely replace or update some remaining components. The new facility
will no longer include Primary Clarification, the process is converting from Extended Air to Oxidation Ditch
and significant upgrades are being made to the control systems for the facility to allow Operators greater
awareness of issues as they arise. This component of the Permit will have to be amended within the next
year as the construction project is approximately 70% complete. We would propose delaying the permit
renewal until that time so that the permit could be implemented correctly with the new facility.
The City of Hickory has great reservation about the addition of such a stringent limitation on Mercury,
especially given the timing in conjunction with the current upgrade. The new facility was not designed
with any special provisions for improved Mercury removal. To quantify the impact of the Northeast
WWTP as a contributory source for Mercury; at the proposed numeric limit of 12ng/I and the permitted
capacity of 6 MGD the City of Hickory Northeast WWTP would contribute as loading of 0.25 pounds per
year. This is a minimal, at best, contribution of Mercury to the waters of the State. Staff has evaluated
the previous 4 year sample history for this parameter and out of those samples the proposed limit was
exceeded 8 times. Coincidentally, each of these exceedance occurred during a substantial rain event.
This further documents our belief that the largest contributory source for Mercury in waters is from non -
point sources, such as rain cleansing the air.
SEP022011
DEN' -WATER QUALITY
POINT SOURCE BRANCH

The City of Hickory would like to request that the proposed numeric limit for Mercury be removed from the
proposed permitted parameters or as a means of compromise that the numeric monthly limit be
established at 36 ng/I matching the proposed daily maximum. This is a very arduous and costly analysis
to perform at this level of detection, especially given the extent of our worst case contribution. In
conjunction with this adjustment to a common numeric limit, the City of Hickory would also like to propose
the formation of a mutually agreeable Mercury Mitigation Plan that would allow us to work in conjunction
with the State and optimize potential for reductions in potential sources, including advancement of
Inflow/Infiltration and Rehabilitation programs that will allow us to reinvest monies into the advancement
of the existing Collection System. In this plan we would like to propose milestones that are negotiated to
achieve a number of improvements over a 3 to 5 year period. The City of Hickory feels this approach
would be meritorious to both the POTW and State programs.
The last item that we request to be considered is for the permit to be modified to recognize the edits to
the Boiler plate language that Mr. Colson and the NC Water Quality Association have been discussing.
These edit relate directly to language and wording edits that will align permit language with Federal
Regulation as appropriate.
Thank you in advance for your consideration of these items. The City of Hickory ahs long enjoyed a
successful, cohesive relationship with NCDENR and we look forward to continuing this relationship. We
sincerely appreciate the Departments efforts in protecting the environment and advancing the importance
of this industry. Should you have any questions please do not hesitate contacting me.

City of Hickory Northeast WWTP Permit No NC0020401 Draft NPDES
We have reviewed the Draft permit for the Northeast WVVTP (NC0020401) NPDES permit renewal and principally agree
with the proposed modifications. The only real concern we have regarding this proposed Draft NPDES Permit is the
recalibration of Mercury. We have charted this parameter against historical actual data and feel that this level will cause
compliance issues for the facility. We respectfully request that this addition be revisited and potentially eliminated. We
currently monitor for this one time monthly and going back to Jan 2008 we would have had 10 instances of violation at this
proposed concentration. We have spoken with other discharger permit holders along the Catawba and every one spoken
with did not have a Mercury Limit or monitoring requirement added to there permit's during the latest renewals, with one
being as recent as July 2011. We feel this permit limit is very restrictive and will result in permit noncompliance for the
NPDES in question. Vye understand that there is great discussion over this item between EPA and NCDENR over the
Assessment Report that was written and a difference of interpretations. The Water Quality Standard for Mercury is well
above this and no allowance for receiving stream dilution is extremely conservative for facilities to achieve who have not
been specifically designed for this removal process through chemical precipitation.
The second item that we have of concern is the timing of this Draft Permit. The Northeast WWTP is currently under
construction for a complete upgrade and replacement. If we renew the current facility at this time we will have to modify
the NPDES permit again in approximately 9 months due to the fact that the Facility Description for Treatment Units will no
longer be accurate. We would request that this renewal be pushed out until after the completion of construction given that
we are approximately 70% complete with construction of a new facility.
Please let me know when would be convenient prior to the end of the comment period for me to call and discuss these
items. I wanted to email first so that you could see out areas of concern prior to my call.
Thank you in advance for your assistance.
Thanks

EPA Region 4 received the draft permit for the City of Hickory in Catawba, County, North
Carolina on July 27, 2011,
Upon review of the City's application attached to the permit package it is noted that the
analytical monitoring for Mercury was performed using a less sensitive method (245.1).
It is also noted that you have addressed this in the draft permit by adding mercury
monitoring and stipulated they use the more sensitive method EPA 1631A. Thank you for
correcting that deficiency in the new draft permit.

NPDES STAFF REPORT AND RECOMMENDATIONS
County: Catawba
NPDES Permit No.: NC0020401
PART I - GENERAL INFORMATION
1. Facility and address: City of Hickory Northeast WWTP
Post Office Box 398
Hickory, N.C. 28603-0398
Physical Location
310 Cloninger Mill Rd
Hickory, NC 28601
2. Date of investigation: January 20, 2010
3. Report prepared by: Michael L. Parker, Environmental Engineer II
4. Person contacted and telephone number: Keith Rhyne, ORC [phone].
5. Directions to site: The WWTP site is located on the right (west) side of SR 1400
(Cloninger Mill Rd., N.E.) 0.15 mile southeast of the jct. of SR 1400 and Hwy. 127 in
northern Catawba County.
6. Discharge point(s), list for all discharge points:
Latitude: 35° 48' 00"
Longitude: 81° 18' 05"
Attach a USGS Map Extract and indicate treatment plant site and discharge point on map.
USGS Quad No.: D 13 SE
7. Receiving stream or affected surface waters: Catawba River (Lake Hickory)
a. Classification: WS-IV, B
b. River basin and subbasin no.: Catawba 030832
c. Describe receiving stream features and pertinent downstream uses: Primary and
secondary recreation (with frequent bodily contact) and as a source of public
water supply. There are no other (known) dischargers between the current
discharge point and a hydroelectric dam (Oxford Dam) located . 8.0 miles below
the point of discharge.

Page Two
PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS
e.
Volume of wastewater: 6.0 MGD (Design Capacity)
What is the current permitted capacity: 6.0 MGD
Actual treatment capacity of current facility (current design capacity): 6.0 MGD
Date(s) and construction activities allowed by previous ATCs issued in the
previous two years: There has been no ATCs issued to this facility in the past two
years.
Description of existing or substantially constructed WWT facilities: The existing
WWT facilities consist of a parshall flume with an ultrasonic flow transmitter
followed by dual influent bar screens (one mechanical and one manual), an
aerated grit chamber, four (4) rectangular and one circular primary clarifiers, eight
(8) aeration basins, two circular secondary clarifiers, a sludge pumping station,
gaseous chlorine disinfection, dechlorination (sulfur dioxide), diffused post
aeration, and two gravity belt sludge thickeners. A stand-by power generator is
available, if necessary.
f. Description of proposed WWT facilities: The permittee is planning an overhaul of
the existing WWTP, which will result in an upgrade of several of the treatment
processes currently being used at this facility as well as new components that will
enhance treatment capability. In 2008, the City submitted a ATC request which
incorporated a number of WWTP improvements that not only allowed for
improved peak inflow control, but provided for nutrient removal in anticipation of
future nutrient limitations due to nutrient enrichment of the receiving waters. On
February 5, 2009, an ATC was issued that authorized a number of WWTP
upgrades, however, bids submitted for this work came in well above the City's
budget for this project. The City then went back to their engineers and looked at
areas where they could reduce the scope of the overall project, but maintain the
integrity of the needed process upgrades. This redesign included using a number
of existing structures rather than constructing new facilities and downsizing (and
even eliminating) some proposed structures. Completion of construction is not
expected until 2011.
PART III - OTHER PERTINENT INFORMATION
1. Compliance information: The last inspection conducted at this facility (December 2008)
did not indicate any issues that would be considered problematic or detrimental towards
maintaining effluent compliance.
2. Special monitoring or limitations (including toxicity) requests: The permittee has not
requested any changes to the current permit's effluent limitations, frequency, sample type,
or sampling location in this permit renewal.

Page Three
PART IV - EVALUATION AND RECOMMENDATIONS
The City of Hickory (the City) requests renewal of the subject permit for the continued
operation of the subject facility. There have been no changes to the current permit and/or
existing WWT facility since the permit was last issued nor is the City asking for any changes to
the permit during this renewal. It should be noted, however, that significant structural changes
to the WWTP are planned during the term of the next permit (see Part II, No. l(f) above).
In reviewing the files for this facility, it was noted that the 7Q10 flow of the receiving
stream for this facility is listed at 60 cfs, which happens to correspond to the minimum release
from Duke Energy's downstream Oxford hydroelectric dam. Recent re -licensing negotiations
with Duke may have resulted in an agreement to provide for a higher minimum release than the
current 60 cfs, so this figure should be verified with USGS prior to permit reissuance.
Pending receipt and approval of the draft permit, it is recommended that the permit be
renewed as requested.

City of Hickory
Northeast WWTP
Process Flow Diagram Narrative
The Northeast Wastewater Treatment Facility is a secondary treatment plant utilizing the
activated sludge process. The plant is designed to treat 6.0 MGD of municipal and
industrial wastewater flows from served locations in Northern Hickory and Southern
Alexander County. The plant is equipped with a generator that is designed to run all
plant processes in case of power failure.
Preliminary Treatment
All plant influent flows discharge to the influent Parshall flume. The flume flow
metering system provides monitoring and recording of influent flow data. The influent
then flows to the headworks building where the barscreens and grit channels are housed.
The wastewater then flows to a division box where the flow is split for further treatment.
Primary Treatment
Following the division box, 58% of the flow goes to the south side of the plant where the
primary settling tanks are. The remaining 42% of the flow goes to the north side of the
plant where the circular primary clarifier is. Sludge and floating solids are physically
removed and sent to the waste sludge pit located at the return sludge pump station.
Secondary Treatment
The primary effluent then flows to two sets of aeration basins, which is mixed and
aerated by, blowers with diffusers. After several hours, the mixed liquor discharges to a
division bpx where the flow is split between two secondary clarifiers. The solids that are
settled in the bottom of the tanks are then sent to the return pump station to be returned to
the aeration basins or wasted from the system via the sludge waste pit. The excess sludge
is then thickened by using gravity belt thickeners and loaded on tanker trucks to be
hauled to the regional compost facility for further treatment.
Final Treatment
The secondary effluent then flows to the chlorine contact chamber where chlorine is
injected through diffusers. Just before the post aeration basin, sulfur dioxide is added.
The effluent then discharges into the outfall line and diffused before released into the
receiving stream.

The City of Hickory's Northeast Wastewater Treatment Plant processes all of its sludge by composting.
Sludge is removed from the aeration basins and placed in a digester to reduce the amount of volatile
solids and to allow the sludge to thicken. Supernate is decanted and returned to the head of the plant.
The thickened solids are dewatered by a belt filter press and taken to the Hickory Regional Compost
Facility (Permit #WQ0004563) in Newton, NC, for further processing into class "A" compost material.
During the composting process, the sludge is stabilized sufficiently to meet all vector attraction and
pathogen reduction requirements. Once dry, the cured compost is distributed to various entities to be
used as a soil amendment.
If additional information is needed, please feel free to contact me at [phone].
