City of Hickory I Henry Fork VW -FF Solids Handling Update — Residuals Distribution Permit Application
Program Information
D.1 Program Narrative
D.1.1 Summary
Biosolids will either come from Henry Fork Wastewater Treatment Facility (WWTF) or other
local facilities. Biosolids from the WWTF will either be primary solids or waste activated sludge
(WAS). Primary solids from the existing primary clarifiers will flow by gravity into the existing
primary sludge (PS) holding basin. WAS from the biological treatment process will be pumped
to the sludge pump station. WAS will be thickened by a gravity belt thickener before being
pumped into either TWAS Holding Basin No. 1 or No. 2. Biosolids from other local WWTFs will
enter Henry Fork WWTF through the Solids Receiving Station and piped to TWAS Holding
Basin No. 1 or No. 2. TWAS will be mixed with PS and pumped to a new belt filter press for
dewatering. From the belt filter press, the TWAS/PS will be transferred via a series of screw
conveyors into the Cake Storage Bin, for holding until processing through the Biosolids Dryer.
Cake will be pumped to the Biosolids Dryer where it will be dried to greater than 90% solids. A
drag conveyor will transfer dried cake to a covered dried product storage area where it can be
collected by or transported to the end user for disposal. A process flow diagram is presented in
the Residuals Management Plan (see Appendix A of the Operations and Maintenance Plan in
Attachment H).
Leachate collection will be handled via a trench drain which will convey all leachate and other
wastewaters generated from biosolids processing to the headworks of the WWTF.
The final product will be distributed via bulk truckloads
D.1.2 Residuals Management Plan
The Residuals Management Plan, submitted and approved by NCDEQ as part of the
Authorization to Construct Permit, provides additional information on materials storage,
handling, and processing. A copy of the plan is included in the Operation and Maintenance
Plan.
D.2 Marketability Statement
Residuals from the Henry Fork Biosolids Processing Facility will be made available to the public
for purchase via bulk truckloads at a mass of up to 4,000 dry tons per year. An information
sheet will be provided to purchasers that details all laws and regulations relating to the
application of Class A residuals. Residuals that are not purchased will be transported to a
landfill for disposal.
D.3 Product Information Sheet
A product information sheet will be provided after sampling is completed.

City of Hickory I Class A Residuals Distribution Permit
Operation and Maintenance Plan
1 Operational Functions
The Henry Fork Wastewater Treatment Facility (WWTF) is owned and operated by the City of
Hickory (City). The City provides all operations, maintenance, and management services for the
facility. The Biosolids Handling Facility, located at the WWTF, provides biosolids processing and
management for the City's WWTFs as well as facilities in the surrounding area. The Residuals
Management Plan in Appendix A outlines the specific functions, capacities, and process flow of the
Biosolids Handling Facility.
2 Maintenance Schedules
Maintenance schedules for process equipment are being completed and compiled as part of the
ongoing construction. This section will be updated when the maintenance schedules are finalized.
3 Safety Measures
The City maintains an Emergency Action Plan (EAP) at the WWTF to assess risks and outline the
emergency response program. The EAP is on file at the WWTF.
Equipment specific safety training and materials are being compiled as part of the ongoing
construction. This section will be updated when materials are finalized.
4 Spill Response Plan
4.1 General
It is the policy of the City to immediately responded to any chemical or biosolids spill. The first step
shall be to secure the affect area, then take all measures to contain the spilled chemical or biosolids.
Documentation of the incident will begin immediately and will be performed by the ORC. All spills will
be immediately reported to the following:
City of Hickory, Utilities Manager, Contact Information
NCDNR, Mooresville Regional Supervisor, Contact Information
All parties transporting biosolids to the WWTF shall be required to have spill response plans on file
with the WWTF.
4.2 Biosolids Spills
Small Spills
Biosolids will be adsorbed on the asphalt or concrete areas by using finished residuals product
and/or an additional absorbent material as necessary. All be material that can be transferred will be
placed in the receiving tanks at the facility.
January 8, 2024 1 i

Henry Fork Wastewater Treatment Facility — Biosolids Operation and Maintenance Plan (DRAFT)
City of Hickory
Large Spills
Measures will be taken to contain the spill area. A pump truck will be called to transfer as much
material as possible to the on -site receiving tanks. If raw biosolids run into grass areas, the runoff
will be mixed with absorbent materials and berms will be constructed as necessary to prevent the
material from reaching surface waters. The contaminated material will then be mixed with sand and
lime for stabilization and hauled off site for disposal at an approved site. Lime will be spread on the
affected area as necessary for disinfection.
4.3 Chemical Spills
All chemical storage tanks have spill containment areas sized to hold the entire volume. Floor drains

City of Hickory I Henry Fork WWTF Solids Handling Facilities Upgrade - Residuals Management Plan
Introduction
1 Introduction
The City of Hickory (City) currently sends their solids to the Regional Sludge Management
Facility (RSMF) operated by Veolia Water North America under contract with the Sludge
Consortium, of which the City is the lead agent (with 66% ownership). This facility receives
solids from the City's WWTFs and other consortium members and produces Class A compost.
The City is currently in the process of significant upgrades to the influent and solids handling
portions of the Henry Fork Wastewater Treatment Facility (WWTF). With these upgrades, there
will be changes to the City's residuals management process. The following plan describes the
new process that will be constructed and operated for treating and disposing residuals from the
wastewater treatment plant process. This plan will eventually replace the existing Residuals
Management Plan for the Compost Facility once the compost facility has been
decommissioned.
1.1 Wastewater Process
The Henry Fork WWTF is a 9.0 MGD Biological Activated Sludge Wastewater Treatment
Facility. The process will consist of an equalization basin, barscreens, vortex grit chamber, two
(2) primary clarifiers, two (2) aeration basins, two (2) secondary clarifiers,
chlorination/dechlori nation, sludge holding tank with aeration, and sludge truck loading facility.
The WWTF discharges into the Henry Fork River, which is a Class C stream in the Catawba
River Basin. The solids handling equipment will entail the following:

City of Hickory I Henry Fork WWTF Solids Handling Facilities Upgrade - Residuals Management Plan
Introduction
1.2 Residuals Characteristics
The Henry Fork WWTF will operate a new dryer process for the treatment of primary and
secondary residuals generated though the WWTF process, as well as off -site solids from
several plants in the region; potential contributors include the following:
• Northeast WWTF (NEWWTF, City of Hickory)
• Hickory Water Treatment Facility (currently sends solids to NEWWTF)
• Hickory -Catawba WWTF (City of Hickory)
• Claremont Mclin WWTF
• Claremont North WWTF
• Conover Newton (Clark Creek) WWTP
• Conover Northeast WWTF
Historical solids data from the RSMF are shown in Table 2.

1.3 Thickening
Waste activated sludge (WAS) produced onsite at HFWWTF will be thickened before mixing
upstream of dewatering with off -site solids (which is primarily TWAS). This will lessen the fluid
load and volumetric flow rate to dewatering and in the holding basins upstream. If HFWWTF
WAS were not thickened, the maximum month volumetric flow rate would overwhelm the
holding basins and the volumetric load to dewatering would be increased. WAS will be pumped
from the secondary clarifier then conditioned with polymer before the gravity belt thickener. The
gravity belt thickener will be sized to handle 660 dry Ibs/hr for 40 hours a week. Thickened
solids will then be sent to the thickened waste activated sludge (TWAS) holding basin.
Redundancy is provided by the dual belt filter press.
1.4 Dewatering
Belt filter presses were selected for dewatering the TWAS. Solids stored in the TWAS and
primary sludge (PS) holding basins will be pumped to the Solids Processing Building,

Introduction
conditioned with polymer and pressed using one (1) of the two (2) belt filter presses, each rated
at 1,950 dry Ib/hr solids feed. Redundancy is provided by the dual belt filter press.
1.5 Filtrate Collection
Filtrate from the new solids handling operations will be collected from the system and will drain
to and flow by gravity to the headworks.
1.6 Drying
Drying is a process used for the stabilization of solids and biosolids by decomposing organic
and inorganic matter via heat. Drying is commonly used in wastewater treatment to significantly
reduce the mass and volume of solids. Dried biosolids product can then be either land applied
by local farmers or landfilled for less cost than cake. The dryer size is based on supplying
enough evaporative capacity to support significant solids stabilization and reach at least 90%
total solids in order to obtain Class A biosolids. The dryer design criteria are seen in Table 3.

1.7 Dried Product Storage
Dried product will be generated from the Dryer every week. It is assumed that land application is
the primary destination for the dried biosolids, but land application periods may only occur twice
per year (based on agricultural practices). Therefore, storage is necessary to accumulate the
dried product until it can be land applied; this accumulation period is approximately 5 months,
assuming 2 periods per year for 1 month duration apiece. The other purpose of Dried Product

City of Hickory I Henry Fork WWTF Solids Handling Facilities Upgrade - Residuals Management Plan
Introduction
Storage is to keep the product dry and prevent precipitation from re -wetting it. The design
criteria are shown in Table 4.
A covered storage structure with a truck loading facility may include the following components
and features:
• Concrete foundation with walls on three sides.
o Walls designed for loads from pushing dried biosolids with heavy equipment.
• Steel framed structure and roof system to keep the product dry.
• Conveyer deposits dried product in one or multiple locations in the structure and
operators manually spread the product out with a bulldozer.
• Paved apron near the open side of the structure for loader access and to load open -top
trucks.
• Trucks loaded with a wheel loader by an operator.

1.8 Compliance Monitoring
Compliance with 40 CFR Part 503 will be met by the following methods:
• Pathogen Reduction - Thermal Process (Dryer) Time and Temperature & Fecal
Coliform Testing for Class A
• Vector Attraction Reduction — 90% total solids minimum
• Metals Analysis — Quarterly prior to application
1.9 Beneficial Reuse/Disposal
Closer to the start-up of the dryer system the City of Hickory will apply for a new Class A permit
to reuse the dried biosolids processed at the Henry Fork WWTF. At a minimum of 6 months
prior to construction completion/start-up the permit application will be developed and submitted
to NCDEQ for development and issue of a Class A Land Application Permit. The City will have
multiple options available for the disposal and beneficial reuse of these solids, options include:
• Land Application of dried biosolids (Class A)
• Disposal through the Catawba County Landfill (Back-up)
4

City of Hickory I Henry Fork WWTF Solids Handling Facilities Upgrade - Residuals Management Plan
Introduction
Prior to construction completion/start-up, the City of Hickory will issue a Request for
Qualifications and will select contractor(s). Upon receiving the new permit, the residuals
contractor(s) will be responsible for beneficial reuse. If beneficial use is not available for any
reason, the City will be responsible for landfill disposal.
