Dear Mr. Ellis:
Dee Freeman
Secretary
Enclosed you will find a copy of the Compliance Evaluation Inspection report for
the inspection that was conducted on February 18, 2009. As part of the inspection a tour
of the Wastewater Treatment Plant was conducted. All observations and recommendations
are in Part D: Summary of Findings/Comments of this inspection report.
. On the day of this inspection, a sludge spill that was contained on site occurred near
the small sludge holding tank. Verbal plans were to put the sludge back into the nearby
manhole that flowed to the aeration basin, clean the ground area, and apply lime to the
contaminated ground area. The sludge spill may have occurred as a result of approaching
the capacity of the sludge holding tanks, and it may follow that the sludge capacity for the
wastewater treatment plant may be inadequate because .of the following: 1) the .sludge
holding tanks were approaching capacity, and 2) the clarifiers had sludge blankets that
were approximately 10 feet in depth (with a clarifier sidewall depth of 13 feet): Please
send this office a written Plan -of Action, due by March 24, 2009, concerning how to
reduce the sludge in the holding tanks and clarifiers, and avoid a sludge spill. Please also
send a written report of the status of the February 18th sludge spill clean up.

On the day of this inspection, a spill'of sludge occurred near the small sludge holding tank. The spill was
contained on site. Verbal plans were to put the sludge .into the nearby manhole that flows to the aeration
basin, and the ground area cleaned up and lime applied to the area. It appeared that there was inadequate
sludge_ capacity, because the sludge holding tanks were nearcapacity and the clarifiers had sludge blankets
that were approximately.10 feet in depth (with a clarifier sidewall depth of 13 feet). In addition, a sludge •
spill occurred on the day of this inspection that may be related to the depth of the sludge in the sludge
holding tanks. .Please send this office awritten Plan -of -Action, due by March 24,.2009, concerning how to
reduce the sludge in the sludge holding tanks and clarifiers, and avoid a sludge spill. Please also send a
written report of the status of the February 18th sludge spill clean up. Please begin testing and recording
the amount of chlorine, sampled immediately before dechlorination in the chlorine contact chamber. Please
note that the flow paced 24-hour effluent composite sampler was set to.pull 150 rnL of sample for each
100,000 gallons of effluent flow (the frequency of grab samples that make up the composite appeared to be
approximately once per hour).

a total clarifier sidewall depth of 13 feet.' The target clarifier depth was 2 to-5 feet of
sludge blanket depth. After the results of the Whole Effluent Toxicity from the week of
February 9, 2009 are received, plans are to take down Clarifier, #2 and Aeration Basin

Standby Power
Comment: On the day. of this inspection, the generator for the influent pump station at
the old WWTP was tested under load. This WWTP facility participates in the load
management program in which, approximately once per month, the power will be turned
off and the generators with automatically come on. This POTW did not have a routine
schedule for running the generators. At the pump station site, the generators are run
once per month. The readings for the generators were read and recorded
approximately every other day to keep track of the time that the generators were run.
Scada will also show and record whether or not a generator comes on. On the day of
this inspection, each of the two large generators had at least three-quarters full capacity
of diesel in the tanks.

Classification of Biological Water Pollution Control Treatment Systems:
Grade I Biological WPCS
- Septic tank sand filter systems.
- Biological lagoon systems
- Constructed wetlands and associated appurtenances
Grade II Biological WPCS
- Systems that utilize an activated sludge or fixed growth process with a permitted flow
less than or equal to 0.5 million gallons per day (mgd)
Grade III Biological WPCS
- Systems that utilize an activated Sludge or fixed growth process with a peintitted flow
of greater than 0.5 through 2.5 million gallons per day (mgd)
- Grade 11 systems that are required to achieve biological nutrient reduction *
Grade IV Biological WPCS
- Systems that utilizing an activated sludge or fixed growth process with a permitted flow
Of greater than 2.5 million gallons pet day (mgd)
- Grade III systems that are required to achieve biological nutrient reduction *
* Biological Nutrient Reduction
The reduction of total nitrogen or total phosphorous by an activated sludge or fixed growth
. process as required by the facilities permit.
Classification of Collection Water Pollution Control Systems:
(whichever provides lowest grade)
Same grade as biological water pollution control system. Grade of system:
Based on population served:
