Inspection Date: 11/16/2020 Inspection Type : Compliance Evaluation
Reason for Visit: Routine
Inspection Summary:
On November 16, 2020, MRO staff performed a Compliance Evaluation Inspection under permit WQ0038341.
During a recent storm event, a tree fell onto a section of chain link fencing. The fallen tree caused approximately twenty feet
of fencing to be damaged. The damaged section of fencing will require repair to be in compliance with the permit. The ORC
indicated that the permittee had been made aware of the fence damage. It is the responsibility of the permittee to maintain
the fencing around the treatment facility.
Additional signage would be helpful to identify the area of the dedicated wastewater irrigation. Only one sign was observed to
be present identifying the drip irrigation area.
Small amounts of garbage were observed along the road of the dedicated drip irrigation field. People not associated with the
WWTP should be prevented from entering the treatment area and the dedicated irrigation field.

Comment: The recent event of elevated Fecal Coliform bacteria has been addressed. New protocol has
been established to address UV light changes and sleeve cleaning or sleeve replacement. The
new SOP will include the sleeve be changed or if possible cleaned whenever the UV light is
replaced. Currently, the UV light is changed annually. However, the ORC has been adivsed to
keep an eye on the monthly Coliform Bacteria counts to check for possible UV light failure.
A third treatment pod has been added to the WWTP. The addition of the new pod has the facilitN
at the current permitted limit. The addition of future pods will require a permit modification.
Treatment Flow Measurement -Influent
Is flowmeter calibrated annually?
Is flowmeter operating properly?
Does flowmeter monitor continuously?
Does flowmeter record flow?
Does flowmeter appear to monitor accurately?

Comment: During the current inspection period, influent flow is not high enough to require monitoring.
Treatment Flow Measurement -Water Use Records
Is water use metered?
Are the daily average values properly calculated?
Yes No NA NE
❑ ❑ • ❑
❑ ❑ • ❑
Comment: The system does not require water metering because the flow has not reached the 10,000 gallor
per day flow that would require a meter to be installed. Currently, average dailly flow is above
8,000 gallons per day. A meter may need to be installed once the development is completely
built out.
Treatment Flow Measurement -Effluent
Is flowmeter calibrated annually?

Comment: The effluent flow meter was installed in February 2020. The Contractor sends the old meter out
for calibration at the end of the annual operation cycle. There is always a meter ready to be
installed if the meter in service becomes damaged or at the end of the annual run cycle. Meter
calibration records were reviewed during the site visit.

Comment: The filter media appeared to be in good condition during the site visit. Scouring operations werE
viewed during the site visit. The spray across the filter media appears to be even. None of the
scouring spray -heads appear to be clogged. The ORC was able to demonstrate how the scour
heads are able to be cleaned.
Treatment Disinfection
Is the system working?
Do the fecal coliform results indicate proper disinfection?
Is there adequate detention time (>=30 minutes)?
Is the system properly maintained?
If gas, does the cylinder storage appear safe?
Is the fan in the chlorine feed room and storage area operable?
Is the chlorinator accessible?
If tablets, are tablets present?
Are the tablets the proper size and type?
Is contact chamber free of sludge, solids, and growth?
If UV, are extra UV bulbs available?

If yes, then is there a Risk Management Plan on site?
If yes, then what is the EPA twelve digit ID Number? (1000-
If yes, then when was the RMP last updated?
Comment: Disinfection is by UV Light. Based on the NDMR reports, Fecal colifom is being adequately
treated.

Comment: The closest water supply well is the last dwelling in relation to the enterance to the treatment
system. This would be greater than 500 ft. The WSW would also be upgrade from the WWTP.
There are no monitor wells asscociated with this system.
The site did display some ponding in the area of zone 9. No damaged emitters were observed
during the site visit. In an attempt to verify that Zone 9 is not causing ponding, the emmiter lines
for zone 9 are to be drained and the soil will be allowed to drain to accept the ponded water. Th(
pondinq may be the result of recent heavy rainfall and soil conditions. It was suggested that soil
auger samples be performed to determine if the soils present in the soil 9 area might cause
water to become perched due to saturation.
During the site visit, the drip irrigation area was reviewed for damaged emmitters. All damaged
emmiters were flagged for repair.
