1. Introduction
INTRODUCTION
The Town of Cleveland is located in the western region of Rowan County within North Carolina.
It is a small municipality, and according to the US Census Data has an estimated population of
852 residents.
The Town of Cleveland owns and operates its own wastewater treatment plant (WWTP) and
collection system. The Cleveland WWTP is located in the Town of Cleveland at 625 Third Creek
Church Road. The WWTP has a permitted capacity of 0.27 million gallons per day (MGD) and
treated an average daily flow (ADF) of 0.13 MGD over the most recent 12-month period. The
WWTP serves approximately 340 residential sewer connections and 53 non-residential sewer
connections. The Cleveland WWTP was originally constructed in 1982 and later received a major
upgrade in 1994. Effluent from the WWTP is discharged into Third Creek, under NPDES
No. NC0049867, which is classified as a Class C Surface Water according to NCDEQ. A copy of
the Town's NPDES permit is included in Appendix A.
Third Creek is located in the Yadkin Pee Dee River Basin, which is subject to the nutrient
management strategy for High Rock Lake. According to NCDEQ's website, "High Rock Lake is
experiencing water quality issues due to algal blooms which may produce harmful toxins and can
cause illness if ingested by humans and pets. The Department of Environmental Quality is
currently drafting new state requirements to address the increased nutrients in this watershed
causing the blooms." Cleveland's WWTP permit may be reopened and modified to implement
nutrient requirements in accordance with any future Total Maximum Daily Load (TMDL) limits.
The Cleveland WWTP was not originally designed for nutrient removal and does not have the
ability to remove nutrients without considerable modification.
The Cleveland WWTP serves one (1) significant industrial user (SIU) via an approved Industrial
User Pretreatment Permit (IUP). Daimler Trucks North America LLC "Daimler" operates its largest
manufacturing facility in the United States on Highway 70 at 11550 Statesville Boulevard. With
over 2,000 daily employees, the facility produces a large portion of the influent flow at the
Cleveland WWTP. The Daimler manufacturing facility was originally constructed in 1989 and has
seen numerous expansions since it was first commissioned.
Refer to Figures 1.1 & 1.2 on the following pages, which identify the specific location of the
Cleveland WWTP and the Daimler manufacturing facility.

2. Reasoning for Wastewater Management Plan
Upon approval of the renewal of the Town of Cleveland's NPDES permit, NCDEQ/NCDWR
required that a Wastewater Management Plan (WWMP) be prepared by a North Carolina
Licensed Professional Engineer on behalf of the Permittee. The intention of the report is to provide
an assessment of the WWTP and "evaluate the structural integrity and operational efficiency of
the facility to ensure integrity of the treatment system." As a result of the report, NCDEQ requested
that an optimization plan be developed to strategize "optimization, rehabilitation, expansion,
and/or replacement of the collection and/or treatment system to achieve optimum performance."
In order to demonstrate progress, the Town of Cleveland is required to provide annualized reports
to illustrate the Town's continued improvement towards achieving and maintaining compliance.
The Cleveland WWTP has a history of non-compliance, totaling a reported sixty (60) Notice of
Violations (NOVs) over the past six (6) years. The overwhelming majority of the NOVs are
exceedance of Biological Oxygen Demand (BOD) limits and Fecal Coliform limits. This report
analyzes these violations and identifies potential causes of these violations, if possible. In an effort
to increase compliance at the Cleveland WWTP, this report will provide strategies to optimize
performance and minimize violations at the WWTP.

3. WWTP Facilities Assessment
COLLECTION SYSTEM
The Town of Cleveland owns and operates its own collection system that includes approximately
8.8 miles of sewer line. Based on the original collection system drawings, the system is primarily
comprised of 8-inch gravity sewers, with the exception of several 12-inch gravity sewers. The
record drawings for the entire collection system are dated January 31, 1984; therefore, it has been
concluded that the collection system was constructed concurrently with the WWTP.
The collection system also includes four (4) sewer pump stations and accompanying forcemains.
All pump stations have been rehabilitated within the past eight (8) years. Most recently, the
Brevard Pump Station was rehabilitated to include new Gorman -Rupp suction lift pumps, new
piping and valves, new pump enclosure, new standby generator, and all new electrical equipment.
At this point, all sewer pump stations are in good working condition and include standby power.

Several wet weather events were analyzed in this wastewater management plan to evaluate the
severity of inflow and infiltration in the Cleveland collection system. It should be noted that the
plant has no means of measuring influent flow; therefore, the effluent flow meter was utilized in
this analysis. Figure 3.1 represents a wet weather event, where a peaking factor of 2.22 was
calculated. Based on the data analyzed, the system experiences moderate levels of inflow and
some levels of infiltration. It should be noted that the WWTP does not have an equalization tank;
therefore, operators have no means of diverting influent flow during peak flow events. Although
the Town of Cleveland does experience surges of flow during wet weather events, there is no
record of sanitary sewer overflows (SSOs) in the system.

As noted previously, the Cleveland WWTP was originally built in 1982 and had a design capacity
rate of 0.09 MGD. The WWTP included an influent structure with manual bar screen, oxidation
ditch, clarifier, chlorine contact chamber, and flow measuring box with v-notch weir. In 1994, the
facility was expanded to the current capacity of 0.27 MGD. This expansion included a new
headworks, flow splitting structure, an additional oxidation ditch and clarifier, aerobic digestor, a
larger chlorine contact basin, and upgraded flow measuring structure to include a parshall flume.
It should be noted that the facility does not have an influent pump station and operates solely by
gravity flow. Figure 3.3 illustrates the process flow diagram from the 1994 expansion project.
The Cleveland WWTP treated an average daily flow (ADF) of 0.13 MGD from January of 2018 to
January of 2023. During this period, the plant exceeded its permitted design flow rate of 0.27
MGD a total of thirty-three (33) times. Furthermore, a maximum daily flow of 0.72 MGD was
recorded. Figure 3.2 illustrates the data described above.

Similar figures are included in Appendix A, displaying the following parameters: influent total
suspended solids (TSS), influent biological oxygen demand (BOD), effluent flow, effluent
dissolved oxygen (DO), effluent BOD, effluent TSS, and effluent fecal coliform.
The only influent parameters regularly monitored at the Cleveland WWTP are TSS and BOD.
Annualized data of these parameters are below:

According to Metcalf & Eddy, Inc, typical domestic wastewater has 100-350 mg/L of TSS and
110-400 mg/L of BOD. Over the entire time range analyzed, Cleveland's TSS has been
exceptionally high. In more recent years, BOD has been above average as well. The Town of
Cleveland staff have been aware of these abnormalities but have not determined the cause. Apart
from Daimler, Cleveland's influent is entirely comprised of domestic wastewater. Daimler's UP
only requires monthly monitoring of its TSS and BOD; therefore, sufficient data is not available to
determine if Daimler is the source of the high TSS and BOD.

HEADWORKS ASSESSMENT
The headworks structure at the Cleveland WWTP includes a perforated spiral screen with a
manual bar rack in a bypass channel. Figure 3.4 depicts this equipment. The screen has %-inch
perforations, which prevent rags, debris, and any other inorganic material from entering the
WWTP and damaging critical equipment such as aerators and pumps. The screen is cleaned by
pressurized wash water and an auger that conveys debris to a trash receptacle.
Figure 3.4 — Headworks Screens
Overall, the perforated spiral screen operates adequately, and successfully prevents inorganics
from entering the plant. During site visits, rags and other debris could not be seen in downstream
treatment components. It should be noted that the perforated spiral screen is not properly
winterized, leaving susceptible components, such as the wash water system, prone to freezing.
During the colder months, Town staff temporarily installs heating elements and tarps around this
equipment.
Directly downstream of the headworks structure is a flow splitting structure, which is equipped
with two (2) slide gates that allow flow to be split between the two (2) downstream oxidation
ditches. An automatic sampler is located at the flow splitting structure and is the site of influent
sampling. The sampler is in poor condition and has reached the end of its useful service life;
therefore, the Town is preparing to replace the sampler in the near future.
OXIDATION DITCHES ASSESSMENT
Oxidation Ditch No. 1 is original to the plant construction and has a design capacity of 0.09 MGD.
The oxidation ditch was originally designed with one (1) brush rotor aerator, but later, Town staff
installed a floating aerator to provide additional aeration. Oxidation Ditch No. 2 was constructed
in 1994 and has a design capacity of 0.18 MGD. The oxidation ditch was designed with two (2)
brush rotor aerators. During site visits, all aerators were in good, operable condition. Furthermore,
it is understood that all aerators operate continuously, with the rare exception of high flow events.
Town of Cleveland Page 9 Cleveland WWTP WWMP
McGill Associates, P.A. June 2023

During such events, aerators will be temporarily suspended to prevent biomass washout. Figure
3.5 depicts Oxidation Ditch No. 2.
Note that Section 6 of this report includes additional discussion of the oxidation ditches and the
activated sludge process at the Cleveland WWTP.
Figure 3.5 — Oxidation Ditch No. 2
J
CLARIFIER ASSESSMENT
The Cleveland WWTP includes two (2) peripheral feed clarifiers, which correspond with each
respective Oxidation Ditch. Clarifer No. 1 is original to the plant construction and has a diameter
of 20'-0" and a depth of 9'-6". Clarifier No. 2 was constructed in 1994 and has a diameter of 26'-
0" and a depth of 14'-0". Recent site visits revealed that the equipment (clarifier mechanism, weirs,
platform, drive, etc.) in both clarifiers are original and have not experienced any major upgrades.
The majority of the equipment is in good, operable condition, with the exception of the RAS/WAS
pumps. Operators have noted deteriorated performance of these pumps, which has led to
extended pump run times.
At the peak hourly flow rate of 0.68 MGD (assumes peak hourly factor (PHF) of 2.5) Clarifier No.
1 has a surface overflow rate of 1,049 gpd/ft2 and Clarifier No. 2 has a surface overflow rate of
1,124 gpd/ft2. According to Recommended Standards for Wastewater Facilities (10 State
Standards), a surface overflow rate of 1,200 gpd/ft2 shall not be exceeded. This confirms that the
clarifiers at the Cleveland WWTP can perform without disturbing the sludge blanket and therefore
Town of Cleveland Page 10 Cleveland WWTP WWMP
McGill Associates, P.A. June 2023

properly produce a concentrated return activated sludge. Weir loading rates were similarly verified
not to exceed the recommended limit of 20,000 gpd/linear feet. Weir loading rates were calculated
at 3,871 gpd/linear feet, and 6,511 gpd/linear feet, for Clarifier No. 1 and Clarifier No. 2,
respectively.

CHLORINE CONTACT ASSESSMENT
A single chlorine contact basin was constructed in 1994 to replace the original chlorine contact
basin that was undersized. The chlorine contact structure utilizes chlorine gas for disinfection and
sulfur dioxide for dechlorination. Chlorine gas is fed via an open channel diffuser into a small
chamber located directly upstream of the chlorine contact chamber. Similarly, sulfur dioxide is fed
into a small chamber located directly downstream of the chlorine contact chamber via an open
channel diffuser. A small sump is located in a corner of the chlorine contact chamber to aid in the
removal of accumulated solids.
The chlorine contact chamber provides thirty (30) minutes of detention time at the design flow
rate of 0.27 million gallons per day (MGD). Since contact time is essential, creating plug -flow
within a chlorine contact basin is essential. It is recommended that length -to -width ratios (L/W)
are at a minimum of 10 to 1 to minimize short circuiting according to Metcalf & Eddy, Inc. The
chlorine contact chamber at the Cleveland WWTP has an approximate 5 to 1 L/W ratio, so it is
assumed that some short circuiting is occurring.
Town of Cleveland Page 11 Cleveland WWTP WWMP
McGill Associates, P.A. June 2023

Figure 3.7 — Chlorine Contact Basin
I
Directly downstream of the chlorine contact basin is the flow measuring structure that contains a
3-inch parshall flume. An automatic sampler is also located at this location and is the site of
effluent sampling. Following the parshall flume, flow is discharged into Third Creek. It should be
noted that there is no means of post -aeration at the WWTP.
SLUDGE TREATMENT ASSESSMENT
The Cleveland WWTP includes an aerobic digestor that was constructed in 1994, which replaced
the original sludge drying beds. Waste activated sludge is pumped from both clarifiers into the
aerobic digestor for several hours each week. Operators have noted that sludge is hauled from
the digestor approximately 3-4 times a year and is land applied.
Based on the original drawings, the aerobic digestor was designed with a floating aerator but was
later replaced with two (2) blowers and a diffused air system. During site visits, the blowers and
aeration system were in good, operable condition. Figure 3.8 depicts the aerobic digester.

4. Pre -Treatment Assessment
As previously noted, the Cleveland WWTP serves one (1) significant industrial user (SIU) via an
approved Industrial User Pretreatment Permit (IUP). Daimler Trucks North America LLC "Daimler"
discharges wastewater into the Cleveland system via an IUP (IUP 0001) that is effective from July
1, 2020 until June 30, 2025. A copy of the permit is included in Appendix B. The facility is located
approximately 3/4 mile south of the Cleveland WWTP.
Daimler's IUP includes two (2) separate regulated pipes. Pipe #001 includes all process
wastewater from metal finishing operations, various washing operations, and fumes from paint
filter booths. A pre-treatment system treats the wastewater before combining with Pipe #002. The
pre-treatment system includes: two (2) 10,000-gallon flow equalization tanks, two (2) 1,000-gallon
reaction tanks, two (2) 600-gallon neutralization tanks for metals removal, one (1) clarifier, one
(1) 2,000-gallon sludge holding tank, one (1) plate and frame press, and all associated chemical
feed equipment. The process flow diagram for this system is shown in Figure 4.2 on the following
page. Flow is monitored daily from Pipe #001 via a trapezoidal flume and has a monthly average
limit of 0.065 MGD.

Pipe #002 includes all domestic wastewater and any discharge water from the various cooling
towers on -site. An 8-inch trapezoidal flume in a manhole is located downstream of the confluence
of Pipe #001 and Pipe #002. Effluent limits and monitoring requirements on Pipe #002 are
identified in Figure 4.3. The majority of effluent parameters are monitored monthly, whereas flow
and pH are monitored daily. Note that the daily flow limit is 0.2 MGD, which is nearly 75% of
Cleveland's WWTP capacity.

Industrial User Forms (IUF) from April of 2022 to April of 2023 are included in Appendix B. These
IUFs include the monitoring data from Daimler. With the exception of slightly exceeding its pH
limit of 10.0 on two (2) occasions, Daimler has remained in compliance with its permit over the
past 12-months. It should be noted that the Town of Cleveland issued Daimler one (1) Notice of
Violation (NOV) in 2022 and two (2) NOVs in 2023. In February of 2022, the NOV was issued due
to a monthly average copper limit exceedance. In February of 2023, an NOV was issued due to
a failure to report daily flow for the dates of August 1 st and August 2nd of 2022. An additional NOV
was issued that month due to a failure to perform monthly sampling in November 2022.
According to the Industrial User Forms (IUF) from April of 2022 to April of 2023, Daimler averaged
0.05 MGD which accounts for approximately 36% of the overall influent flow at the Cleveland
WWTP during that time frame. Furthermore, a maximum effluent flow of 0.14 MGD was recorded
in the IUFs. Figure 4.4 compares the effluent flow from Daimler to the Cleveland WWTP effluent
flow. Note the correlation between the effluent flow from Daimler and the Cleveland WWTP flow.
In particular, note the increase in Daimler's effluent around July/August of 2022 and its direct
impact on the flow at the Cleveland WWTP.

several occasions where Daimler discharged more than 0.10 MGD for several consecutive days.
These above -average surges of flow from Daimler have historically caused biomass washout at
the Cleveland WWTP. Biomass washout occurs when microorganisms in the oxidation ditches
are flushed out at a faster rate than they can be replenished, which consequently damages the
plant's ability to treat the influent wastewater. In particular, these washout events have occurred
when surges in flow were not anticipated by the Town of Cleveland. The Town of Cleveland has
questioned Daimler regarding these surges, but no definitive response has been provided. It has
been speculated that these surges are caused by malfunctioning cooling towers at the Daimler
facility.

5. WWTP Non -Compliance
The Cleveland WWTP has a history of non-compliance with sixty (60) NOVs reported over the
past six (6) years. Note that this analysis only pertains to non-compliance issues that have been
reported on DEQs Laserfiche website. The table below summarizes the NOVs from 2018 to 2023.

It should be noted that over the time period identified above there were two (2) Notice of
Deficiencies (NOD) issued for varying reasons. Furthermore, although there were significant
trends of non-compliance, there were no Special Orders by Consent (SOCs) issued.
As indicated in the table above, there were a total of twenty (20) NOVs issued in 2019 due to
effluent exceeding BOD limit requirements. Eighteen (18) of these NOVs were due to violations
occurring within the first six (6) months of 2019. It is suspected that the majority of these violations
were caused by a microorganism die -off at the WWTP. Investigations performed by the Town
revealed that biocide and industrial grade cleaners had been introduced to the sewer system via
a local elementary school. As a result of these events, the Town reseeded its activated sludge by
various means including the introduction of sludge from a neighboring plant, which provided
benefit to the WWTP.
The additional BOD exceedance violations were reportedly blamed on high flow events caused
by precipitation. On August 31, 2019, the WWTP received two (2) BOD violations:
1. BOD Weekly Average Exceeded — 23.2 (22.5 Limit)
2. BOD Monthly Average Exceeded — 15.28 (15.0 Limit)
DMR data during this time indicated a monthly average flow of 0.15 MGD, and a daily maximum
of 0.21 MGD (WWTP averaged 0.14 MGD in 2018). Although the plant did record above average
flow during August, it was marginal. DMR data from more recent years has indicated that the plant
has encountered high flow events, without exceeding its BOD limits. Therefore, it can be
concluded that the operators during the 2018 violations were not well equipped with strategies of
handling high flow events.
Nine (9) NOVs were issued in late 2020 and into early 2021 for exceeding fecal coliform limits.
Note that during this time, the Town was experiencing staffing issues due to both resignations
Town of Cleveland Page 18 Cleveland WWTP WWMP
McGill Associates, P.A. June 2023

and the COVID-19 pandemic. Due to these issues, identifying the cause of the fecal coliform
violations was prolonged. Investigations performed by the Town eventually identified that a valve,
designed to allow flow to bypass the chlorine contact basin, was either open or partially open
during the time of fecal coliform violations. Figure 5.1 shows the piping configuration around the
chlorine contact basin.

As a result of these violations, the Town engaged McGill Associates to design a second chlorine
contact basin. This project would provide the Town with full redundancy so that a chlorine contact
basin can be removed from service for cleaning/maintenance operations. This project has been
suspended as the Town is now pursuing a project to construct a new WWTP downstream of the
existing WWTP, which will have an expanded capacity. The new plant will be well equipped to
position the facility to avoid NOVs in the future.
In February of 2023, the Town received a total of sixteen (16) NOVs all related to insufficient
monitoring as required by its NPDES permit. All monitoring issues were related to upstream
sampling, which should be conducted at least 100 feet upstream from the WWTP's discharge
point. According to the Town's NPDES permit, all instream sampling requirements are
provisionally waived if the Town is a participant in the Yadkin/Pee Dee River Basin Association.
Documentation was provided to NCDEQ by the Town confirming its participation in the
Yadkin/Pee Dee River Basin Association following the issuance of these NOVs. In conclusion,
and at the time of this report, it is believed that these NOVs are erroneous, and will be eliminated
from the Town's record.

6. Operations Assessment
OPERATIONS DISCUSSION
Operators of the Cleveland WWTP are typically on -site Monday through Friday for approximately
2-3 hours per day. McGill Associates visited the WWTP during these regular operation hours and
met with the operators. The following observations are a result of the site visits:
1. Influent Flow Monitoring: The Cleveland WWTP does not have an influent flow meter to
measure the flow entering the plant. Consequently, this makes it challenging for operators
to identify surges in influent flow and make the necessary adjustments to ensure a
compliant effluent. The only means of measuring flow at the WWTP is at the effluent;
therefore, when surges occur, necessary adjustments are often delayed.
2. Balancing Flow: As noted previously, the Cleveland WWTP includes two (2) trains, each
train equipped with an oxidation ditch and a clarifier (See Figure 3.3). In order to split flow
between the trains, a flow splitter box is located upstream of the oxidation ditches. The
plant was originally designed such that: One-third (1/3) of the influent flow is sent to train
1, and two-thirds (2/3) of the influent flow is sent to train 2. Operating the plant in this
manner is difficult as it is challenging to split the flow in this precise manner. Operators
must adjust slide gates in the flow splitter box in an effort to achieve the desired split flow.
In consequence, it is easy for operators to send more flow to train 1 than intended by the
design. This can lead to train 1 being overloaded and solids building up in this train.
3. Chemical Feed: Current operating procedures at the chlorine contact basin involve setting
both chlorine gas and sulfur dioxide feed rates and maintaining those feed rates for an
extended period. As the plant flow rate varies throughout a given day, the Cleveland
WWTP risks underfeeding chemicals when surges in flow are not anticipated. In some
cases, WWTPs have flow -paced chemical feed systems, where feed rates are
automatically adjusted with the plant flow rate. Although having flow -paced chemical feed
systems would be helpful at the Cleveland WWTP, it is not a necessity.
OPERATOR HISTORY
The Town of Cleveland has experienced significant staffing turnover at the WWTP in the past six
(6) years. As could be expected, valuable knowledge and experience is lost each time an operator
or ORC is lost, and new personnel are trained. With this situation, the WWTP is left vulnerable
with inexperienced operators and becomes susceptible to non-compliance. The figure below
outlines the ORCs over the past six (6) years and identifies when each NOV was reported.

As depicted on the previous page, a large portion of the NOVs issued by NCDEQ were during the
time period when Paul Land was ORC of the Cleveland WWTP. The additional NOVs were issued
during 2020 and the first several months of 2021 when the Town was experiencing rapid turnover.
It should be observed that since John Ritchie became the ORC of the Cleveland WWTP, the plant
has operated almost within 100% compliance of its NPDES permit. The only exception to this is
the recent (February 2023) monitoring violations that were discussed in Section 5 of this report.
PROCESS MONITORING
Following the review of the WWTP DMRs and daily monitoring reports, McGill Associates
requested that additional process monitoring be conducted to develop a thorough understanding
of the facility operations. The list below identifies additional daily tests that were conducted from
May 2, 2023 until May 22, 2023.
Influent
• Dissolved Oxygen (DO)
• pH
Aeration Basins
• Dissolved Oxygen (DO) in three (3) locations
• pH at Influent
• pH at Effluent
• Settleability Test
Clarifiers
• pH at Influent
• pH at Effluent
• Sludge judge test at two (2) locations
Chlorine Contact
• Dissolved Oxygen (DO) at Effluent
• pH at Influent
• pH at Effluent
• Chlorine Gas Usage (Ibs/day)
• Sulfur Dioxide Usage (Ibs/day)
Aerobic Dipestor
• pH
• WAS duration
Note that daily monitoring of both TSS and MLSS would have been desired in various locations,
but the Town does not currently own a portable settable solids meter. Therefore, settleability tests
were conducted in the locations identified above. Operators performed settleability tests by filling
a 1000mL cylinder and monitoring/recording how the solids settled over time. The test also
provided an opportunity to test the likelihood of sludge -bulking. All process monitoring testing
results may be located in Appendix B.
Town of Cleveland Page 22 Cleveland WWTP WWMP
McGill Associates, P.A. June 2023

The majority of the results from the process monitoring appear to be typical for a small WWTP,
with the exception of the following:
1. Influent Dissolved Oxygen: The influent dissolved oxygen (DO) at the Cleveland WWTP
is lower than typical domestic wastewater, which is believed to be caused by Daimler.
Based on historical data, the Cleveland WWTP has no issues handling this irregularity.
2. MLSS: Although the MLSS in the oxidation ditches was not directly measured, an
approximation of the MLSS can be estimated based on the settleability tests conducted.
Based on McGill's estimations, the MLSS is higher than what is recommended by standard
design documents.
SLUDGE & SOLIDS HANDLING
Managing the activated sludge process at a WWTP is critical to achieving the required degree of
treatment. Managing the activated sludge process in a WWTP is performed by maintaining
dissolved oxygen levels in the oxidation ditches and adjusting both the return activated sludge
(RAS) rate, and the waste activated sludge (WAS) rate. The above are typically adjusted such
that the following parameters (at a minimum) are maintained in a recommended range:
• Mixed Liquor Suspended Solids (MLSS) in oxidation ditches
• Mean Cell Residence Time (MCRT) or sludge age
• F:M (Food/Microorganism) Ratio
• Sludge Blanket in Clarifiers
For example, when MLSS levels are below the recommended range, operators must increase the
RAS rate. Since the RAS/WAS pumps are currently not operated via variable frequency drives,
the quantity of flow must be regulated by the pump run time. Furthermore, it should be noted that
the Cleveland WWTP does not have a means of measuring RAS/WAS flow, such as a magnetic
flow meter, making it exceedingly difficult to maintain the above parameters. Although, if the pump
flow rate is known, and the pump run time is known, a quantity of sludge can be determined.
When sludge is wasted at the Cleveland WWTP, it is pumped to the aerobic digestor. From this
point, sludge is typically hauled 3-4 times a year and land applied. Land application is highly
dependent on weather conditions and is more conducive during summer months when dryer
conditions exist. Because of this, sludge sometimes accumulates during the winter months when
land application is not feasible.
A typical operational problem of an activated sludge process is the proliferation of filamentous
microorganisms in the mixed liquor. This can result in poorly settling sludge, which is referred to
as "bulking sludge". Although the Cleveland WWTP is prone to the development of filamentous
microorganisms based on its inherent design, site visits and the process monitoring did not reveal
any issues related to bulking sludge.

7. Optimization Plan
As a result of the assessment conducted by McGill Associates, the following improvements are
suggested to optimize performance and increase compliance at the Cleveland WWTP. The
strategies and improvements outlined below are separated into two (2) categories. The first
category addresses operational modifications that can be conducted by Cleveland staff. The
second category of improvements include modifications to the treatment process or collection
system.
OPERATIONAL STRATEGIES & IMPROVEMENTS
The following operational improvements should be conducted by the Town of Cleveland:
1. Additional Daily Process Monitoring: Similar to the process monitoring that was conducted
as part of this report, it is recommended that some additional daily monitoring is continued.
The primary purpose of the additional monitoring is to ensure that the biological process
remains healthy at all times. The parameters listed below shall be conducted daily:
a. Influent pH
b. MLSS (mg/L) in Oxidation Ditches
c. Sludge in Clarifiers
2. Process Monitoring Devices: In order to perform additional process monitoring as
described in the item above, the following monitoring device(s) are recommended:
a. It is recommended that a portable settable solids meter from a manufacturer such
as HACH be purchased by the Town. The instrument shall be purchased with a
minimum 25-foot cord with intermediate marks for indicating depth. This instrument
would provide the Town with instantaneous TSS and MLSS measurements, which
the Town has no means of measuring at this time. It is imperative that the Town
have the ability to monitor MLSS as it is a critical parameter to the biological
process and ensuring there is an appropriate quantity of microorganisms to
consume the organic pollutant load.
3. Regular Wasting Plan: Current operations include wasting sludge 1-2 times per week for
2-4 hours each time. In lieu of wasting in this manner, McGill recommends developing a
formalized wasting plan. Utilizing parameters such as MLSS in the oxidation ditches, and
suspended solids in the plant effluent, an optimal wasting duration can be calculated. This
ensures that the mean cell residence time (or sludge age) remains in a target range and
guarantees that a healthy mass of microorganisms exist in the activated sludge process.
4. Consider Revising Daimler's IUP: The Town of Cleveland should consider revising
Daimler's IUP to address the concerns discussed in previous sections of this report. McGill
Associates is currently under contract to complete a Headworks Analysis for the Town of
Cleveland, which is due on September 1st, 2023. The findings of the Headworks Analysis
may dictate the necessary revisions to Daimler's IUP.
5. Standard Operating Procedure (SOP): It is recommended that the Town of Cleveland
develop a Standard Operating Procedure for the WWTP. By doing so, the Town can more
Town of Cleveland Page 24 Cleveland WWTP WWMP
McGill Associates, P.A. June 2023

efficiently train new operators during times of turnover and ensure that valuable
information is properly documented. It also guarantees that all operators perform in a
similar manner and important tasks are not overlooked. This written manual would provide,
at a minimum, the following:
a. Daily Operating Procedures
b. Sampling & Monitoring Procedures & Schedule
c. DMR & Reporting Guidelines
d. Maintenance Procedures & Schedule
e. Regular Wasting Plan (as discussed above)
f. Responses to Common Issues
i. The SOP shall include guidelines on how operators shall respond to
specific issues such as: how to address high flow events or how to respond
to high influent pH events.
WWTP MODIFICATIONS & IMPROVEMENTS
The following WWTP modifications and improvements should be conducted by the Town of
Cleveland:
Replacement of RAS/WAS Pumps & Control Panel: As previously discussed, operators
have reported deteriorated performance of the RAS/WAS pumps, which has led to
extended pump run times and inadequate supply of return activated sludge to the
oxidation ditches. At the time of this report, new RAS/WAS pumps have been purchased
by the Town of Cleveland but have not been delivered and installed. The new RAS/WAS
pumps will be operated via new control panels and variable frequency drives (VFD's).
2. Inflow/Infiltration Identification & Reduction: As previously discussed, the collection
system experiences moderate levels of inflow causing increases in flow at the WWTP.
The Town has a previously established plan to combat 1/1 by smoke testing and/or CCTV
testing to identify locations of 1/1. The Town smoke tested approximately 50% of the
collection system in 2022 and plans to repeat this effort in 2024 by testing the remaining
50% of the collection system. These efforts will allow sources of inflow to be addressed,
which will consequently reduce peak flows at the WWTP during wet weather events.
The Town of Cleveland has begun preliminary work for a proposed project that will increase the
WWTP capacity from 0.27 MGD to 0.6 MGD, while addressing phosphorus and nitrogen limits. It
is proposed that the facility will be relocated approximately 3,000 feet downstream of the existing
plant since the current site does not have adequate space for expansion. In March of 2023, The
Town was awarded a Pre -Construction Planning Grant from the American Rescue Plan Act
(ARPA) for $175,000. Utilizing these funds, an engineering alternative analysis and NPDES
permit modification application will be prepared and submitted. This project is an important need
of the Town to ensure adequate sewer capacity for future growth in the community and
surrounding areas. Note that this "improvement" has not been included in the optimization plan
due to the variety of uncertainties surrounding this project.

[15A NCAC 02S .0200]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 3.0%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," (Revised December 2010, or
subsequent versions) or "North Carolina Phase I1 Chronic Whole Effluent Toxicity Test Procedure"
(Revised December 2010, or subsequent versions). The tests will be performed during the months of
March, June, September, and December. These months signify the first month of each three-month
toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during
representative effluent discharge and 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 -December 2010, or subsequent versions).
All toxicity testing results required as part of this permit condition will be entered electronically using the
Division's eDMR system for the months in which tests were performed, using the parameter code
TGP3B for the pass/fail results. and THP3E for the Chronic Value. Additionally, DWR Form AT-3
(original) is to be sent to the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, NC 27699-1621
Or, results can be sent to the email, ATForms.ATB@ncdenr:gov.
Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 chemicailphysical measurements and all
concentrationlresponse 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 "trio Flow" in the comment area of the fort. The report shall be submitted to the
Water Sciences Section at the address cited above.
Should the pennittee fail to monitor during a month in which toxicity monitoring is required, monitoring
will be required during the following month. Assessment of toxicity compliance is based on the toxicity
testing quarter, which is the three-month time interval that begins on the first day of the month in which
toxicity testing is required by this permit and continues until the final day of the third month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and
modified to include alternate monitoring requirements or limits.
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.
