NPDES Diagnostic Evaluation
Northview Mobile Home Park WWTP (Permit No. NC0067342)
1. Introduction
During the week of July 16, 2018, representatives of the U.S. Environmental Protection Agency
(USEPA) Region 4 Science and Ecosystem' Support Division (SESD) and the North Carolina
Department of Environmental Quality (NCDEQ) conducted a National Pollutant Discharge --
Elimination System (NPDES) Diagnostic Evaluation (DE) of the Northview Mobile Home Park
Wastewater Treatment Plant (WWTP) in Weaverville, North Carolina. The inspection was
requested by the NCDEQ Asheville Regional Office to evaluate the plant's treatment
performance and operation, and to collect samples from the influent and effluent. The effluent
samples were evaluated to determine if the treated wastewater was within permit limits. The
following people listed in Table 1 participated in the inspection.

The diagnostic evaluation included the following tasks:
• Assessing the design, operations, and management factors limiting treatment
performance.
• Review of operations and management of the wastewater treatment plant.
• Evaluation of the unit process performance via visual observations, field
measurements, sampling, data review, and process control testing.
• Determination of the unit process operating parameters (e.g. TSS, TVSS, F/M,
SVI, and Sludge Age).
SESD ID: 18-0570 Final Report Page 4 of 58

• Evaluation of the NPDES self -monitoring program, including sampling, flow
measurements, records and reports, and laboratory procedures.
2. Background
The Northview Mobile Home Park WWTP is a privately -owned municipal wastewater treatment
plant that serves Northview Mobile Home Park, consisting.o£approximately 170 mobile homes.
The facility is designed to operate as an extended aeration plant that consists of an original
package plant with an aeration basin, Imhoff clarifier, and digester, as well as a newer aeration
basin, circular clarifier, and chlorine contact chamber. It is permitted to discharge 0.032 MGD to
receiving waters designated as Flat Creek in the French Broad River Basin. Currently, the facility
- is under a Statutory Tap Moratorium because the NCDEQ Asheville Regional Office deemed it
unable to adequately treat the volume of wastewater flow it receives daily.
3. Summary and Recommendations
The purpose of this Diagnostic Evaluation was to evaluate the overall operation and maintenance
of the plant's treatment systems, review the operating records, and historical data relevant to
plant operations associated with permit requirements, and provide technical recommendations to
improve plant's performance. SESD evaluated the Northview Mobile Home Park treatment
processes and facility conditions, flow measurement system, sludge handling procedures, and
NPDES sampling. This report reflects the operation and configuration of the WWTP at the time
of the inspection.
.During the evaluation, two 24-hour composite influent wastewater samples were collected from
the headworks of the plant. In addition, three 24-hour effluent composite samples were collected
just before the outfall location. Influent and effluent samples were analyzed for Biochemical
Oxygen Demand (BODs), Total Suspended Solids (TSS), Ammonia (NH3), Nitrite -Nitrate
(NO3- NO2), Total Kjeldahl Nitrogen (TKN), Total Phosphorus, and Alkalinity. In -situ
parameters (pH, dissolved oxygen (DO), Total Residual Chlorine, -and temperature) were also
measured at the effluent sampling location.
Grab samples were collected from the two aeration basins and analyzed for TSS and Total
Volatile Suspended Solids (TVSS) to gather more information for process control testingand
operating calculations. In -situ parameters (pH, .dissolved oxygen, specific conductivity, and
temperature) were measured in both basins'as well.
The major findings were as follows:
• The circular clarifier had, sludge blanket depth covering 8.5 feet out of 10 feet total
depth, and the polishing clarifier had 5.5 feet covering 10 feet total depth.
• During the inspection, it was observed that the circular clarifier weir plates were
covered in solids when the influent flow rate increased. (See photo # 7, #12).
SESD ID: 18-0570 Final Report Page 5 of 58

• The dissolved oxygen .levels in the aeration basins were below 1 mg/L, right after the
aeration diffused blowers were turned off. The blowers are set to run 15 minutes every
hour. DO levels recommended for extended aeration are 1 to 3 mg/1(Meticalf & Eddy,
2014)
• The secondary flow measurement device was showing inconsistent readings during the
time of the inspection and was not within the accepted accuracy requirement of f 10 %
of the primary flow measurement device. Outlined in Table 2, the facility's secondary
device was 66% — 69.4% lower than the instantaneous flow check made at the primary
device.
• There was no permanently installed staff gage to measure the water level above the weir
plate.
• The flow totalizer was not functioning properly during the inspection.
• There were noticeable amounts of floating solids and debris in the chlorine contact
chamber. (See photo # 9).
• The effluent sample setup was not properly installed. The sample tubing dips
downward over the chlorine contact chamber side wall into a PVC pipe before being
routed to the automatic sampler. This creates a section of tubing that could improperly
store the wastewater, adversely affecting the purging cycle of the sampler.
• The Total Residual Chlorine measured at the pipe opening just before outfall was 370
µg/L, well above the permit limit of 28 µg/L.
Recommendations are as follows:
• Continue to monitor sludge levels throughout the plant and waste. more frequently to
prevent accumulation of sludge in the clarifiers. As conditions permit, sludge should
not be removed more the 10 percent above previous levels during sludge wasting cycles
to allow the biological system to stabilize and allow the operators to adequately assess
plant conditions.
• Consider modifying the aeration schedule to better balance the on/off cycle which will
create a more stable environment for the microorganisms. The mixed liquor DO levels
-.and effluent pH should be carefully monitored, more frequently if necessary to help
achieve the right balance.
• Install a measurement device such as a staff gage so that the water level above the weir
can accurately be measured.
• Have scheduled maintenance plans in place for broken equipment, such as the flow
totalizer, to repair it on a timely basis.
• Modify the effluent sampling tubing setup so that there are no unnecessary dips in the
line that could affect the purge cycle of the sampler.
• Determine the correct dosage of chlorination and dechlorination tablets required to
adequately disinfect the effluent flow without exceeding the permit limits for Total
Residual Chlorine.
4. Facility Site Review
The WWTP is configured as an extended aerated system. Modifications to the original package
plant include the addition of the new aeration basin, circular clarifier, and contact chamber. (See
Figure 1). Influent wastewater enters the plant (see photo # 1) and splits between the new and old
SESD ID: 18-0570 Final Report Page 6 of 58

aeration basins and the equalization basin. (See photo # 4, # 5). Following aeration, the flow
from both basins is sent to the circular clarifier. Return activated sludge (RAS) is diverted back
to the aeration basins, and waste activated sludge (WAS) is thickened and decanted in the
digester before being hauled to a landfill. Afterwards the circular clarifier, flow is sent to a
polishing clarifier (Imhoff tank). The old chlorine contact chamber serves as an additional
retention unit -before flow enters the new contact chamber, where tablets are used to chlorinate
and dechlorinate the effluent before final discharge. The old chlorine contact chamber wuld.be
used to chlorinate the effluent, and the new contact chamber could be used to allow proper
detention time for disinfection: Currently the chlorination and dechlorination is all applied in the
new chlorine dontact chamber seen in Figure 1.
Figure 1 shows the flow diagram of the'facility as determined by the facility operator and by
visual observation during the inspection. Table 9 in Appendix A lists the size of each treatment
unit, measured during the inspection.

5. Permit
The Northview Mobile Home Park WWTP permit (NC0067342) became effective on April 1,
2018 and will expire on March 31, 2023. The Northview Mobile Home Park and the wastewater
treatment plant serving the homes are both owned by the Eaven Brice Partnership. Under the
permit, the Eaven Brice Partnership can operate the existing 0.032 MGD extended aeration
wastewater treatment facility, and after obtaining an Authorization to Construct permit from
NCDEQ, construct and operate a 0.050 MGD facility to incorporate more wastewater from new
homes.
SESD ID: 18-0570
Final Report

6. Records and Reports
As part of a settlement agreement with NCDEQ, the facility is required to submit monthly
process control logs that show process control weekly results. The log shows dissolved oxygen
and MLSS concentrations in the aeration basins, settlometer test results, clarifier sludge blanket
depth, solids removed from the digester, and average flow: At the time of inspection, .the facility
was reporting the log each month. The facility should continue to perform the process control
checks and maintain process control logs each month to help track the facility's solids inventory
and manage proper solids wasting.
It was observed in the June 2018 and August 2018 logs that process control results for sludge
blanket depth weren't consistently recorded. The facility should keep track of the sludge blanket
depth in the clarifiers and dissolved oxygen levels and settlometer test results for both aeration
basins. This will help to provide information of possible process control adjustments to ensure
that both basins are operating efficiently.
7. Flow Measurement
The effluent flow measurement system is composed a of 90 ° v-notch weir -primary device and an
ultrasonic flow meter as a secondary flow measurement device. At the time of the inspection the
flow meter totalizer wheel was not recording flow. Additionally, the digital instantaneous flow
reading was very inconsistent. The digital value was fluctuating from 1 gallon perminute to
upwards of 40 gallons per minute in a five-minute time span.

Shown in Table 2, comparisons between the primary and secondary flow devices were made by
converting the instantaneous head measurement from the 900 v-notch Weir to instantaneous flow
measurement and comparing that value with the secondary ultrasonic sensor instantaneous flow
reading. The two comparisons between the primary and secondary flow devices indicated a flow
measurement difference of 66.0% and 69.4% which is outside the USEPA accepted accuracy
range off10% difference.
'SESD ID: 18-0570 Final Report Page 8 of 58

Deficiency:
The facility's flow meter is outside ofthe 10 % difference with the primary flow device. The
flow totalizer was not recording flow on the -paper. wheel.
Regulatory Requirement: 40 CFR, Part 122.41 (e); Proper Operation and Maintenance.
The permittee shall at all times properly operate and maintain all facilities and systems of
treatment and control and related appurtenances which are installed or used by the permittee to
achieve compliance with the conditions of this permit. According to the "APDES Compliance
Inspection Manual, 2017, " The permittee's flow measurements should be within 10 percent of the
inspector's measurements to certify accurate flow measurement.
8. Sludge Handling
The Northview Mobile Home Park WWTP uses a septic tank company to dispose sludge from
the digester. At the time of the inspection, the circular clarifier had a sludge blanket depth of 8.5
feet. '(See photo # 11). The total depth of the clarifier is 10 feet. Additionally, the polishing
clarifier (Imhoff tank) had a sludge blanket of 5.5 feet with a total depth of .10 feet. 'The chlorine
contact chamber also had a sludge blanket of 0.25 feet with a total depth of 7.5 feet. (Note: the
accumulated sludge in the chlorine contact chamber was pumped before the sludge depth
measurement was taken). Typically, the sludge blanket depth should be kept to less than one-
fourth of the clarifier sidewall water depth (CSU 2008).
During the inspection, the digester was determined to have a storage capacity of about 3000
gallons. (See Table 9). Based on the amount of sludge build up throughout the plant, the facility
should waste more sludge to the digester'.
On July 18, 2018, the facility had its digester pumped and the waste disposed of in a nearby
landfill. (See photo # 3, # 15). Based on the sludge depth throughout the plant, it is
recommended that the operator increase gradually the amount of WAS. Sludge management is a
critical component to properly operate an activated sludge treatment system.
9. Sampling
9.1 Facility Sampling
The permittee collected samples according to the sampling frequencies and sample types
described in the permit. The facility collected the effluent flow composite samples with an
automatic sampler. At the time of the inspection, it was difficult to observe the facility's sampler
collect a sample aliquot. The sampling frequency was sporadic and didn't correlate to the flow
composite sampler that the USEPA set to tun at the same time as the facility.
Deficiency:
EPA also observed that the tubing running from the sampling location to the composite sampler
did not allow the sampler to properly purge the tubing before collecting a sample aliquot. The
SESD M: 18-0570 Final Report Page 9 of 58

sample tubing should not have unnecessary bends or dips because it can store effluent
wastewater during the purge cycle.
Regulatory Requirement:
40 CFR, Part 122.41 (e),'Proper Operation and Maintenance. The permittee shall at all times
properly operate and maintain all facilities and systems of treatment and control and related
appurtenances which are installed or used by the permittee to achieve compliance with the
conditions of this permit.
Recommendation:
The facility should reconfigure the tubing setup, by removing the current PVC conduit and adjust
the slope of the PVC conduit underground to avoid tubing bending.
9.2 USEPA Sampling Activities
During the inspection, sampling was conducted to determine if the facility was meeting its
effluent permit limits as well as to characterize the influent waste stream and to evaluate the
operating parameters of the plant. On July 16, 2018, sampling equipment was setup at the
facility's influent and effluent locations to collect 24-hour composite samples. (See'photos # 2, 9,
and 13). After collecting the samples on July 18', 2018, the samplers were programmed to collect
a second set of 24-hour composite samples. Process control samples in both the new and old
aeration basins (ASB) were collected to measure the TSS and TVSS concentrations. These
samples were collected as grab samples..
Additionally, a third effluent composite sampler,paced by constant 15-minute intervals was set
upon July 17, 2018; because of difficulties using a flow meter to pace the sampling. The
difficulties encountered while setting up the flow meter were because there was no staff gage to
measure the water level above the weir plate and the ability to accurately determine the level
using a handheld level. See photo #10.
Table 3 shows a comparison of USEPA influent analytical results and typical influent
wastewater concentrations. The strength of the incoming TSS, BOD5, NH3, and TKN
concentrations was high. This high strength influent is typical in plants of which the only influent
source are single residential areas such as mobile home parks. There are no other inflow and .
infiltration sources to dilute the incoming waste concentration which is typically seen at larger
domestic wastewater treatment plants.

Deficiency:
The Total Residual Chlorine was 370 µg/L, which exceeds the daily maximum permit limit.
Regulatory Requirement:
NC0067342 Section 3.A.(1) states that the Total Residual Chlorine daily maximum is 28 µg/L.
Recommendation:
The facility should adjust the amount of chlorination, and dechlorination to meet permit limits.
9.4 USEPA Process Control Results
The following process control tests were conducted:
• Settlometer test, dissolved oxygen profile in the aeration tanks, and sludge blanket
depths in the clarifiers.
• Microorganism evaluation of grab samples from aeration basins using a standard
phase/contract microscope. (See photo # 14).
• Unit process operating parameters were also'calculated to determine if the
hydraulic and organic loadings were within the recommended range of operation
and design for an extended aeration unit.
Table 6 outlines the results of the process control tests and calculations conducted during the
inspection. Based on the results and visual observations, the facility is operating with excess
solids. This is evident by a low F/M ratio (high concentration of microorganisms, MLVSS
compared to food, BODs), high sludge blanket depths. in both clarifiers, and a sludge age that is
on the high range. Additionally, the dissolved oxygen profile indicates that the current blower
schedule is causing the aeration basins to go into anoxic states shortly after blowers are cycled
off.: At the time of the inspection, the blower schedule was set to run for 15 minutes every hour.
The facility should evaluate the volume of solids in its system and gradually remove more solids
on a regular basis. This will lower the MLSS concentration in the aeration basin, reduce the
SESD ID: 18-0570 Final Report Page 12 of 58

/
sludge blanket depths in the clarifiers and prevent further solids loss during peak flow events.
Typically, facilities use an operating strategy for sludge wasting such as maintaining a target
F/M ratio, constant-MLVSS concentration, or target Mean Cell Residence Time (MCRT).
Additionally, the blower on/off cycle should be evaluated to maintain the aeration basins DO
levels above 1 mg/L, (recommended DO levels: 1 mg/L to 3 mg/L). This will create a healthy
biomass environment. A gradual reduction in the solids inventory would allow for proper DO
levels with less aeration requirements and subsequently less power consumption. Careful
consideration of the plant's effluent quality should be noted when making changes to the solids
inventory.

9.4 USEPA Sampling Methodology
SESD conducted the sampling activities following the Sample Analysis Plan (SAP) prepared for
the project. All USEPA sampling methods, measurements, and calibrations were conducted in
accordance with USEPA Region 4 SESD procedures listed in the SAP. Samples were analyzed
at the SESD laboratory in accordance with the Analytical Support Branch (ASB) Laboratory
Operations and Quality Assurance Manual. The ASB laboratory is accredited -under the EPA
Region 4 ASB's ISO/IEC 17025 accreditation issued by ANSI-ASQ National Accreditation
Board/ACLAS.
10. Effluent and Receiving Waters
The final effluent was clear; however, there were visible solids observed floating on top in the
chlorine contact chamber just before the effluent weir plate. (See photo # 9).

USEPA calculated the operating parameters using the USEPA diagnostic evaluation sampling
results.
Based on the difficulties verifying flow, results will, be calculated using the instantaneous flow
measured with surveying equipment.
Hydraulic Retention Time (HRT)
• V = VNCW-A5B + V01d-A5B = •053411 MG + .026828 MG = 0.080239 MG

Settlometer Test
The settlometer test was performed to observe the settling characteristics of the mixed liquor,
assess sludge quality, and approximate age. A settlometer test was conducted at the plant using
an undiluted 1,000 mL sample and a 50% diluted sample collected at both the New-ASB and
Old-ASB.

DATA QUALIFIER DEFINITIONS
U The analyte was not detected at or above the reporting.limit.
J The identification of the analyte is acceptable; the reported value is an estimate.
K The identification of the analyte is acceptable; the reported value may be biased high. The actual value is expected
to be less than the reported value.
L The identification of the analyte is acceptable; the reported value may be biased low. The actual value is expected
to be greater than the reported value.
ACRONYMS AND ABBREVIATIONS
CAS Chemical Abstracts Service
Note: Analytes with no known CAS identifiers have been assigned codes beginning with "0, the EPA ID as assigned by
the EPA Substance Registry System (www.epa.gov/srs), or beginning with "R42', a unique identifier assigned by the EPA
Region 4 laboratory.
MDL Method Detection Limit - The minimum concentration of a substance (an analyte) that can be measured and
reported with a 99% confidence that the analyte concentration is greater than zero.
MRL Minimum Reporting Limit - Aayyte concentration that corresponds.to the lowest demonstrated level of acceptable
quantitation. The MRL is sample -specific and accounts for preparation weights and volumes, dilutions, and
moisture content of soil/sediments.'
TIC Tentatively Identified Compound - An analyte identified based on.a match with the instrument software's mass
spectral library. A calibration standard has not been analyzed to confirm the compound's identification or the
estimated concentration reported.
