SUBJECT: Requested documents for the City of Lenoir Biosolids Permit Renewal Request
WQ0010059
Dear Mr. Katyal,
The City of Lenoir is requesting a permit renewal for the Distribution of Class A Residuals for
permit number WQ0010059, of which was submitted but other documents and clarifications
were requested.
I have included in this package the clarifications and other documents that were requested.
The City of Lenoir currently has 3 major sources: Lower Creek WWTP sludge, Gunpowder
Creek WWTP sludge, and Lake Rhodhiss WTP sludge which are all introduced into the sludge
holding tank and mixed before being dewatered and sent to the landfill.
We are requesting that the Town of Blowing Rock be added as a resource. I am resubmitting
the RSC form and other documentation as requested.
The Town of Blowing Rock will not be required to submit a VAR as the sludge is hauled to
Lower Creek Biosolids facility in a 4,000 gallon tanker truck owned and operated by the Town
of Blowing Rock to be introduced directly into the sludge holding basin and mixed with all the
other sludges for de -watering and drying.
Construction is due to be completed by December 2020 on the new gas dryer system that will
dry the sludge to 90% which will meet the pathogen reduction requirements of fecal coliform
density, the time/temperature requirement and Vector Attraction Reduction requirement by
drying of stabilized residuals for the final product.
Sincerely,
EU'5� Tv,LPlett

OPERATION AND MAINTENANCE PLAN FOR CITY OF LENOIR LOWER CREEK WWTP
BIOSOLIDS TREATMENT FACILITY
1. The City of Lenoir Lower Creek Biosolids Facility will be accepting sludge from
the Town of Blowing Rock, the City of Lenoir Gunpowder Creek WWTP, and
the City of Lenoir Lake Rhodhiss WTP. The City of Lenoir owns a 7,000 gallons
tanker truck and the Town of Blowing Rock owns a 4,000 gallon tanker.
Respective City of Lenoir and Blowing Rock employee will haul the sludge from
those facilities to the Lower Creek WWTP Biosolids treatment facility, where it
is introduced directly into the sludge holding tank. All the sludges introduced
into the holding tank will be mixed and aerated before being pumped to the
belt press for further processing.
2. Operation of the Program. Sludge, from the Sludge Holding Tank is
thickened by the belt press before being fed into the Thermal Belt Dryer. The
proposed dryer will produce over 90% solids and provide biosolids particles in
excess of 1769 F for pathogen reduction. The system will also dry un-stabilized
solids to over 90% for vector attraction reduction. Gryphon is able to verify
Class A biosolids compliance by 1) monitoring of process temperatures,
moisture contents, and cycle times, 2) drying the solids to over 90% solids, and
3) verifying fecal coliform levels by lab analysis. The percent solids content
must be measured at least once per day at the following locations: feed sludge
to belt press; thickened sludge from belt press; and the final dried product.
The daily flow of feed sludge must be documented (calculated from the sludge
meter readings). All of the above listed activities are performed by the
biosolids treatment operator.
3. Maintenance Schedule. The sludge flow meters are calibrated by a third -
party on an annual basis. The Public Utilities maintenance staff will be
responsible for maintaining the hydraulics of the belt press, the electrical
operations of the system, and major overall system operations including
malfunctions. The Condenser Filter for the Thermal Belt Dryer is swapped,
cleaned, and inspected daily by Public Utilities Staff. The Cooling Tower and
Condenser Coil for the Thermal Belt Dryer are flushed monthly. The Injection
Plate and Externals of the Cooling Tower for the Thermal Belt Dryer are
cleaned/washed on a monthly basis.
4. Safety Measures. Biosolids treatment operators and maintenance staff must
comply with PPE requirements. This includes the use of disposable latex or
nitrile gloves, heavy duty water proof gloves, when appropriate, and face
masks in the Class A production area. Signage is provided within the Residuals
Building indicating areas that require hearing protection and areas
designated as confined spaces. Upon inspection of the application site, the
City spreader truck driver should ensure that there are no dangerous slopes
to traverse, as the truck is top-heavy when loaded.
5. Spill Response. All spills in the biosolids treatment and storage area are
routed to floor drains, which go to the influent of the WWTP. There are no
bulk liquid hazardous chemicals used in the process. All sludge from parking
lot and Class A area is routed back to the plant influent.
If a spill were to occur from the spreader truck in transit to the application
site, the driver must stop as soon as it is discovered. The superintendent of
WWTP must be notified immediately with the following information:
Elisa Triplett: Superintendent Wastewater Treatment
Telephone: 828-757-2198
Email: Irtriplett@CI.LENOIR.NC.US
It may be necessary to notify city police, sheriff's department, or highway
patrol, so that traffic can be controlled while cleanup is taking place. If
needed, additional personnel will be dispatched to assist in the cleanup. As
much product as possible should be shoveled up and put back into the
spreader truck; remaining solids should be swept up. Prior to leaving the
biosolids storage area, any biosolids overspill on the spreader truck should
be swept as clean as possible.
6. Inspection Plan. The following personnel are responsible for inspections of
the biosolids treatment system prior to operation (before each shift):
a. Jonathan Whisnant, Biosolids Operator
b. Jake Soots, Biosolids Operator
Daily inspections of the Belt Filter Press include verifying that that the wash
system is properly operating, ensuring proper belt tracking, inspecting the
belt for excessive wear and inspecting the equipment of foreign debris such
as plastic and inorganic materials. Daily Inspections of the Thermal Belt Dryer
include the following:
Conveyor Belt —tracking
ii. Conveyor Belt — binding and wear
iii. Leveler Section — brush
iv. Heater Functionality— pressure and flow
v. Chamber Temperatures
vi. Condenser Coil Inspection
vii. Sifter Assembly -Brush and Screen — binding and wear
viii. Dryer Chamber — spray wash functionality
ix. Cooling Tower — water temp and water supply
If it is found that the system cannot be run in compliance, safely or efficiently,
the system must not be operated unless the problems are corrected. If
problems are found, the personnel listed above must contact one of the
following:
c. Elisa Triplett, Superintendent Wastewater Treatment
d. Donnie Hawkins, ORC
e. Tommy Mann, Superintendent Public Utilities Maintenance
Application site inspections are the responsibility of the actual land applier,
hauler, or spreader truck driver. When biosolids are actually applied by the
City driver, the driver will have to make sure that all permit requirements are
met, including buffer zones for application. The current driver with those
responsibilities is:
f. Jerry Denny
If it is found that the biosolids application procedures cannot meet
compliance, safely or efficiently, biosolids cannot be land applied until the
problems are corrected. If problems are found, the personnel listed above
must contact either of the following:
g. Elisa Triplett, Superintendent Wastewater Treatment
h. Tommy Mann, Superintendent Public Utilities Maintenance
A copy of this plan, as well as a copy of the Utilization Agreement will be kept
inside the spreader truck. The Utilization Agreement will be given directly to
self -haulers.
7. Sampling and Monitoring Plan. Sampling of the final product is conducted
in accordance with the residuals permit. The sampling frequency is once per
quarter for metals, nutrients, fecal coliform bacteria, pH, and percent solids.
The exact parameters are listed in the permit. Actual frequency is based on
the amount of final product applied to the land. A TCLP analysis on the final
product is conducted annually typically during the winter months. The
laboratory / pretreatment staff are responsible for the sample collection and
transport to the contracted lab(s). The individual responsible for sample
collection is:
a. Matthew Mackie, Pretreatment Assistant.
Below is a description of sampling procedures:
b. For TCLP, metals, nutrients, and total solids, the storage pile is
sampled in at least ten (10) different locations. The samples are mixed
to make a "composited" sample, from which the final sample taken to
the lab is taken. At least two (2) bags are collected along with two
more for any analyses sent to another lab besides the regular contract
lab (currently arsenic, lead, and selenium are being sent to Statesville
Analytical, Statesville, NC; all other parameters and TCLP are being
sent to Blue Ridge Labs, Lenoir, NC).
• For Fecal Coliform sampling, seven (7) samples are collected from
different areas of the pile and placed in separate bags. The seven samples
are transported so that they can be analyzed within 24 hours.
