RE: NPDES Permit Renewal Application (NPDES NC0020401)
City of Hickory— Northeast WWTP
Hickory, NC
Dear Sir or Madam,
Enclosed for your review and processing you will find the application package for the renewal of
the City of Hickory's— Northeast Wastewater Treatment Plant NPDES permit. Included in this
cover letter is a brief narrative explaining the biosolids management plan for the Northeast
Wastewater Treatment Plant, as well as a request for this plant to be designated as an
Exceptionally Performing Facility.
The application package includes the following:
• NPDES Form 2A
o Part A
o Part B
o Part C
o Part D
o Part E
o Part F
• Plant Flow Schematic/Narrative
• Attachment for Part B
• Attachment for Part E
• Attachment for Part F
• Exceptionally Performing Facility (EPF) JustificEtion and Statistical Analyses
The City of Hickory's Northeast Wastewater Treatment Plant processes all of its sludge by
composting. Sludge is removed from the secondary clarifiers and dewatered by a gravity belt
thickener with the addition of polymer. The thickened solids are stored in a thickened sludge tank
before being loaded into tankers and taken to the HiCkor/ Regional Compost Facility (Permit#
WQ0004563) in Newton, NC, for further processing into;:lass"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 for use as a
soil amendment.

The City of Hickory is requesting reduced monitoring for this facility per the Exceptionally
Performing Facilities guidance. The Northeast WWTP facility meets all of the requirements for the
reduced monitoring. There were no civil penalties assessed during the past three years; the
permittee nor any of its employees have been convicted of criminal violations under the clean
water act within the last five years; the facility is not under an SOC; and the facility is not on the
EPA's Quarterly Noncompliance Report. Attached you will find the justification and statistical
analysis to support the designation of this plant as an Exceptionally Performing Facility.
Thank you in advance for your review. Should you have any questions regarding this submittal,
please do not hesitate to contact me at(828) 323-7427 or via email at cbvnum ac hickorync.gov.

SUPPLEMENTAL APPLICATION INFORMATION
PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1)POTWs with a design flow rate greater than or equal to 1.0 mgd;2)POTWs with a pretreatment program(or those that are
required to have one under 40 CFR Part 403);or 3)POTWs required by the permitting authority to submit data for these parameters.
• At a minimum,these results must include quarterly testing for a 12-month period within the past 1 year using multiple species(minimum of two
species),or the results from four tests performed at least annually in the four and one-half years prior to the application,provided the results
show no appreciable toxicity,and testing for acute and/or chronic toxicity,depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition,this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition,submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity,provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation,if one was conducted.
• If you have already submitted any of the information requested in Part E,you need not submit it again. Rather,provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used,report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below,they may be submitted in place of Part E.
If no biomonitoring data is required,do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to

Process Flow Narrative
Northeast WWTP,NC 0020401
Permit Renewal- Catawba Basin
The Northeast Wastewater Treatment Facility is a secondary treatment plant utilizing the
Oxidation Ditch process. The plant is designed to treat 6.0 MGD of municipal and industrial
wastewater flow from the Northern Hickory and Southern Alexander County service areas. The
plant is equipped with two backup generators that are designed to run all plant processes in the
event of power failure.
Flow enters the plant via a 42-inch gravity sewer line into the main influent channel. It is then
split into two parallel channels that each contain an automatic mechanical bar screen. After
flowing through the bar screens the two channels rejoin and flow through a parshall flume. This
provides a measurement of the influent flow before it enters the influent lift station. The influent
lift station pumps wastewater to the headworks structure,which also contains the grit removal
system. Wastewater flows from the grit removal system and enters one of the two oxidation
ditches. The oxidation ditch is a three stage ditch that includes aeration equipment, and is
designed for biological nutrient removal. Wastewater then overflows the effluent weir gates and
enters a splitter box before being routed to the secondary clarifiers. Settled sludge from the
secondary clarifiers enters the RAS/WAS pump station, and is either pumped beck to the
oxidation ditch as return activated sludge, or to the truck loading station as waste activated
sludge. The effluent from the clarifiers flows to the chlorine contact chamber for chlorination,
and at the end of the chamber sulfur dioxide is added prior to post aeration. The effluent then
discharges into the outfall line and is diffused before being released into the receiving stream.
