Operation and Maintenance Plan
US Biosolids, Inc.
North Wilkesboro WWTP
Permit No. WQ00037135
In accordance with the requirements as issued by the North Carolina Department of
Environmental Quality using NCGS 143-215.1 and 143-215.3(a) based on 15A NCAC 02T .110,
the Town of North Wilkesboro and U.S Biosolids, Inc. are implementing this Operation and
Maintenance Plan.
The Land Application of Non-Dedicated Class B Residuals from the Town of North Wilkesboro
will be conducted from the Wastewater Treatment facility, located at 100 Thurmond Road North
Wilkesboro, NC 28659. Residuals will be removed and given away to farmers to be used as a
soil amendment. The residuals will be removed on as needed bases as fluctuation in the output of
the plant will vary with changing economic conditions. The day-to-day operation of the running
of the Wastewater Treatment will be conducted by Scott Perry, ORC of North Wilkesboro
WWTP or his/her designee. The operations of the land application program will be conducted by
Zach Key of U.S Biosolids, Inc. or his/her designee.
Land application of residuals will be determined once enough residuals have been produced from
the treatment of the residuals to fill the residuals holding tank to 2/3 capacity. The land
application event is initiated by North Wilkesboro Wastewater Treatment plant contacting U.S.
Biosolids, Inc. U.S. Biosolids, Inc. will plan and start a land application event. The residuals will
be pumped from the residuals holding tank and loaded into tanker trucks. These trucks will
transport the residuals to the land application site, where they will be loaded onto a liquid
spreader for land application onto permit sites. The residuals will not be stored on the ground at
any time.
Prior to land applying these residuals to permitted sites, the following sampling conditions must
be met(as is outlined in greater detail in the sampling plan attached to this Operation and
Maintenance Plan).
Toxicity Characteristics Leaching Procedure (TCLP) will be conducted once per
year, if a land application event takes place.
A metals and nutrients analysis, pathogen and vector attraction, and soil analysis will be
conducted annually if a land application event takes place.
These samples will be collected by Zach Key of U.S. Biosolids or his/her designee and
transported to an approved lab the same day the samples are taken, as in accordance with 15A
NCAC 02B .0505. The samples must be taken in a matter to ensure a representative sample of
the residuals has been taken.
An inspection will be conducted daily while a land application event is taking place. This
inspection will confirm that all requirements of permit WQ0037135 are complying with

regulations. The fields should be inspected daily for compliance with the conditions that is
outline in then permit. The inspection should consist of(but not limited to):
1. All required setbacks and buffers are complying.
2. All required record keeping of truck and fields sheets are maintained and properly filled
out so accurate records of the volume and locate of residuals are keep.
3. All public access points are controlled (signs posted, gates closed)
4. Make sure all fields' records are turned over to the ORC so records can be reviewed by
NCDEQ and an annual report can be constructed.
The daily land application inspection will be conducted by the following personal:
Dennis Key, ORC U.S. Biosolids, Inc.
Zach Key. BORC U.S. Biosolids, Inc.
If any issues or violations are discovered, the ORC of Land Application, Baxter Healthcare
Corporation and the Asheville Regional Office should be contacted as soon as safely possible.
o ORC of Land Application, US Biosolids, Inc. 336-957-7878
o North Wilkesboro WWTP 336-838-5001
o Winston Regional Office 336-776-9800
To prevent any spills and or safety issues from occurring the flowing will take place during a
land application event. In the unlikely event of a spill consult the spill control plan immediately.
1. Access to the facility will be controlled with a locked gates and fences and signs to
prevent any unauthorized entry into the complex.
2. All pumps and hose will be checked at the start of each day for leaks or loose
fittings.
3. All tanker valves are closed prior to loading and lids are closed prior to transport.
4. All dump trailers or dump trucks gates are tightly fastened and do not leak prior to
transport.
5. All on road equipment is check as per DOT regulations for any safety or mechanical
hazards or issues.
6. All equipment is secured at the end of each working day to prevent any tampering or
unauthorized use.

7. Enough freeboard is maintained in the residual digesters so to prevent overflowing.
This can be accomplished by maintaining the levels of residuals to an acceptable level
by planning adequate land application events to keep up with residuals production.

SAMPLING PLAN
Annually, if a land application event occurs, grab samples are collected from the residuals
holding tank. These samples will be combined to form individual grab samples to be sent to a laboratory
for analysis.
These individual grab samples are collected and tested for fecal coliform analysis,volatile solids
reduction, nutrient analysis, and a TCLP test. These tests will be taken by Zach Key of U.S. Biosolids, Inc.
All samples apart from the composite residual sample will be taken to Statesville Analytical. The
composite residual sample will be sent to Waypoint Analytical.All samples taken will be taken in the
same condition as the residuals are to be land applied.
The volatile solids reduction requirement will first be attempted by using option 1 [503.33(b)
(1)1; Reduction of volatile solids by at least 38%. The "IN" sample will be taken from the residuals
pumped from the clarifiers and the "OUT" sample from residuals holding tank. If this requirement can't
be met, a gallon of residuals will be sampled from the aerobic digester and analyzed for option 3
503.33(b) (3); known as a 30 day bench scale. This test requires less than 15%additional volatile solids
reduction during bench-scale aerobic batch digestion for 30 days. If a passing 30 day bench scale is not
achieved,vector attraction will be met using alternative 6-alkaline stabilization.
Fecal Coliform are gathered in seven (7) individual samples from the residuals holding tank and
tested to meet the requirements of[503.32(b)(2)). This requirement is for the geometric mean fecal
coliform density of the samples be less than two million (2,000,000) MPN per gram. These samples will
be placed in 250m1 containers and placed on ice, in a cooler for transport to the laboratory before 1600
hours (4pm)the same day the samples are obtained.
Annually, if land application occurs, a composite residual sample will be collected and analyzed,
prior to a land application event for: Cadmium, Copper, Lead, Mercury, Molybdenum, Nickel, Selenium,
Zinc, Aluminum, Ammonia Nitrogen, Calcium, Nitrate Nitrogen, Magnesium, %total Solids, pH,
Phosphorus, Potassium, TKN, Sodium. From this information, the Plant Available Nitrogen (PAN) and a
Sodium Absorption Ratio (SAR) will be calculated. This sample will collected in a non-breakable
container, at least one quart in size.
A full TCLP test, including corrosivity, ignitability, and reactivity will be taken in two (2) gallon
containers from the aerobic digester.This test will be run annually unless prior approval is granted from
the division to reduce this requirement to once per permit cycle.

the Town of Lowell and U.S Biosolids, Inc. are implementing this Operation and Maintenance
Plan.
The Land Application of Non-Dedicated Class B Residuals from the Town of Lowell will be
conducted from the Wastewater Treatment facility, located at 100 Saxony Dr. Lowell, NC
28098. Residuals will be removed and given away to farmers to be used as a soil amendment.
The residuals will be removed on as needed bases as fluctuation in the output of the plant will
vary with changing economic conditions. The day-to-day operation of the running of the
Wastewater Treatment will be conducted by Dan Dougherty, ORC of Lowell WWTP or his/her
designee. The operations of the land application program will be conducted by Zach Key of U.S
Biosolids, Inc. or his/her designee.
Land application of residuals will be determined once enough residuals have been produced from
the treatment of the residuals to fill the residuals holding tank to 3/4 capacity. The land
application event is initiated by Lowell Wastewater Treatment plant contacting U.S. Biosolids,
Inc. U.S. Biosolids, Inc. will plan and start a land application event. The residuals will be
pumped from the residuals holding tank and loaded into tanker trucks. These trucks will
transport the residuals to the land application site, where they will be loaded onto a liquid
spreader for land application onto permit sites. The residuals will not be stored on the ground at
any time.
Prior to land applying these residuals to permitted sites, the following sampling conditions must
be met (as is outlined in greater detail in the sampling plan attached to this Operation and
Maintenance Plan).
Toxicity Characteristics Leaching Procedure (TCLP) will be conducted once per
year, if a land application event takes place.
A metals and nutrients analysis, pathogen and vector attraction, and soil analysis will be
conducted annually if a land application event takes place.
These samples will be collected by Zach Key of U.S. Biosolids or his/her designee and
transported to an approved lab the same day the samples are taken, as in accordance with 15A
NCAC 02B .0505. The samples must be taken in a matter to ensure a representative sample of
the residuals has been taken.
An inspection will be conducted daily while a land application event is taking place. This
inspection will confirm that all requirements of permit WQ0037135 are complying with

regulations. The fields should be inspected daily for compliance with the conditions that is
outline in then permit. The inspection should consist of(hut not limited to):
1. All required setbacks and buffers are complying.
2. All required record keeping of truck and fields sheets are maintained and properly filled
out so accurate records of the volume and locate of residuals are keep.
3. All public access points are controlled (signs posted, gates closed)
4. Make sure all fields' records are turned over to the ORC so records can be reviewed by
NCDEQ and an annual report can be constructed.
The daily land application inspection will be conducted by the following personal:
Zach Key, ORC U.S. Biosolids, Inc.
Dennis Key, BORC U.S. Biosolids, Inc.
If any issues or violations are discovered, the ORC of Land Application, Baxter Healthcare
Corporation and the Asheville Regional Office should be contacted as soon as safely possible.
o ORC of Land Application, US Biosolids, Inc. 336-957-7878
o Lowell WWTP 704-477-5514
o Mooresville Regional Office 704-663-1699
To prevent any spills and or safety issues from occurring the flowing will take place during a
land application event. In the unlikely event of a spill consult the spill control plan immediately.
1. Access to the facility will be controlled with a locked gates and fences and signs to
prevent any unauthorized entry into the complex.
2. All pumps and hose will be checked at the start of each day for leaks or loose
fittings.
3. All tanker valves are closed prior to loading and lids are closed prior to transport.
4. All dump trailers or dump trucks gates are tightly fastened and do not leak prior to
transport.
5. All on road equipment is check as per DOT regulations for any safety or mechanical
hazards or issues.
6. All equipment is secured at the end of each working day to prevent any tampering or
unauthorized use.

7. Enough freeboard is maintained in the residual digesters so to prevent overflowing.
This can be accomplished by maintaining the levels of residuals to an acceptable level
by planning adequate land application events to keep up with residuals production.

WASTEWATER TREATMENT PLANT PROCESS
The Town of North Wilkesboro operates a 2.0 MGD facility which utilizes an aerobic digestion
process. The facility treats domestic waste and influent from several industries in North
Wilkesboro. Primary settled solids and final settled solids are pumped into one of two 2.5 million
gallon aerobic digesters or basins. Sludge from the basins are decanted to a thickener where it is
sent to the sludge holding tank alter the achievement of 3% to 5% solids. Biosolids are removed
from the sludge holding tank and land applied as needed,
A process schematic for the Town of North Wilkesboro WWTP is presented on the following page.

Quantitative Justification for Residuals Production Rate.
The town of North Wilkesboro land applied 234.27 dry tons in the calendar year of 2021.This is the
highest number of residuals the Town of North Wilkesboro has produced since the town started a land
application program.
The 300 dry tons requested in this permit modification package will allow for the increased production
of residuals and will allow for future growth in the residual production rate.

US Biosolids, Inc.
North Wilkesboro WWTP
Permit No. WQ0037135
SAMPLING PLAN
Annually, if a land application event occurs, grab samples are collected from the residuals
holding tank.These samples will be combined to form individual grab samples to be sent to a laboratory
for analysis.
These individual grab samples are collected and tested for fecal coliform analysis,volatile solids
reduction, nutrient analysis, and a TCLP test. These tests will be taken by Zach Key of U.S. Biosolids, Inc.
All samples apart from the composite residual sample will be taken to Statesville Analytical. The
composite residual sample will be sent to Waypoint Analytical. All samples taken will be taken in the
same condition as the residuals are to be land applied.
The volatile solids reduction requirement will first be attempted by using option 1 [503.33(b)
(1)J; Reduction of volatile solids by at least 38%. The "IN" sample will be taken from the residuals
pumped from the clarifiers and the "OUT" sample from residuals holding tank. If this requirement can't
be met, a gallon of residuals will be sampled from the aerobic digester and analyzed for option 3
503.33(b) (3); known as a 30 day bench scale.This test requires less than 15%additional volatile solids
reduction during bench-scale aerobic batch digestion for 30 days. If a passing 30 day bench scale is not
achieved, vector attraction will be met using alternative 6-alkaline stabilization.
Fecal Coliform are gathered in seven (7) individual samples from the residuals holding tank and
tested to meet the requirements of[503.32(b)(2)J.This requirement is for the geometric mean fecal
coliform density of the samples be less than two million (2,000,000) MPN per gram. These samples will
be placed in 250m1 containers and placed on ice, in a cooler for transport to the laboratory before 1600
hours (4pm) the same day the samples are obtained.
Annually, if land application occurs, a composite residual sample will be collected and analyzed,
prior to a land application event for: Cadmium, Copper, Lead, Mercury, Molybdenum, Nickel, Selenium,
Zinc,Aluminum, Ammonia Nitrogen, Calcium, Nitrate Nitrogen, Magnesium, %total Solids, pH,
Phosphorus, Potassium, TKN, Sodium. From this information, the Plant Available Nitrogen (PAN) and a
Sodium Absorption Ratio (SAR)will be calculated. This sample will collected in a non-breakable
container, at least one quart in size.
A full TCLP test, including corrosivity, ignitability, and reactivity will be taken in two (2) gallon
containers from the aerobic digester.This test will be run annually unless prior approval is granted from
the division to reduce this requirement to once per permit cycle.

Town of Lowell, NC
Waste Water Treatment Plant
Residual Process Description
Influent flows through a bar screen into an extended aeration chamber for a detention time of
24 hours, based on a flow of 300,000 gallons, (if volume is less, time is longer). From the chamber the
sludge flows into energy baffle diffuser in the center of the clarifier.Clarification occurs; floatable scum
is removed by a skimmer arm to a scum trough, then to the digester or the aeration chamber. Activated
sludge is constantly being returned from the clarification process to the chamber.
The supernatant from the clarifier flows through saw tooth weirs into a contact chamber where
it is aerated and chlorinated; then over a v-notched weir flow measuring device; then into an unnamed
tributary of the Long Creek.
Residuals in the bottom of the clarifier unit are either returned to the aeration chamber, or
wasted to the digester for thickening, then the removal to the drying beds prior to transport to the
landfill or held for land application. When volatile solids reduction is measured at a rate less than 38%, a
30 day bench scale is taken, if unable to pass the 30 day bench, lime stabilization will be utilized to land
apply the residuals. Waste materials left on the bar screen are removed and taken to the landfill.

Quantitative Justification for Residuals Production Rate.
The town of Lowell is estimated to produce 50 dry tons of residuals per year at its current production
rate.The 200 dry tons requested in this permit modification package will allow for growth and any clean
outs of the digesters that may be required from time to time.

US Biosolids, Inc.
Lowel l-W WTP
Permit No. WQ0037135
SAMPLING PLAN
Annually, if a land application event occurs, grab samples are collected from the aerobic
digesters.These samples will be combined to form individual grab samples to be sent to a laboratory for
analysis.
These individual grab samples are collected and tested for fecal coliform analysis,volatile solids
reduction, nutrient analysis, and a TCLP test. These tests will be taken by Zach Key of U.S. Biosolids, Inc.
All samples apart from the composite residual sample will be taken to Statesville Analytical. The
composite residual sample will be sent to Waypoint Analytical. All samples taken will be taken in the
same condition as the residuals are to be land applied.
The volatile solids reduction requirement will first be attempted by using option 1 [503.33(b)
(1)]; Reduction of volatile solids by at least 38%.The "IN" sample will be taken from the residuals
pumped from the clarifiers and the "OUT" sample from aerobic digester No. 1. If this requirement can't
be met, a gallon of residuals will be sampled from the aerobic digester and analyzed for option 3
503.33(b) (3); known as a 30-day bench scale. This test requires less than 15%additional volatile solids
reduction during bench-scale aerobic batch digestion for 30 days. If vector attraction reduction can't be
meet with alternative 1 nor 3, alternative 6-alkaline stabilization will be used.
Fecal Coliform are gathered in seven (7) individual samples from the aerobic digester and tested
to meet the requirements of [503.32(b)(2)J. This requirement is for the geometric mean fecal coliform
density of the samples be less than two million (2,000,000) MPN per gram.These samples will be placed
in 250m1 containers and placed on ice, in a cooler for transport to the laboratory before 1600 hours
(4pm) the same day the samples are obtained.
Annually, if land application occurs, a composite residual sample will be collected from the
aerobic digester, prior to a land application event for: Cadmium, Copper, Lead, Mercury, Molybdenum,
Nickel,Selenium, Zinc,Aluminum, Ammonia Nitrogen, Calcium, Nitrate Nitrogen, Magnesium, %total
Solids, pH, Phosphorus, Potassium,TKN, Sodium. From this information, the Plant Available Nitrogen
(PAN) and a Sodium Absorption Ratio (SAR)will be calculated. This sample will collected in a non-
breakable container, at least one quart in size.
A full TCLP test, including corrosivity, ignitability, and reactivity will be taken in two (2)gallon
containers from the aerobic digester. This test will be run annually unless prior approval is granted from
the division to reduce this requirement to once per permit cycle.
