Good Afternoon Mr. Guerra,
We recieved the Draft NPDES Permit noted above for the City of Monroe John Glenn WTP.
We offer the following comments related to this permit renewal:
• General: The added limits and monitoring requirements contained in the permit
will place additional cost burdens to the City of Monroe water customers and
demands on our limited WTP staff. The whole effluent toxicity testing is particularly
burdensome and expensive.
• Stream Impairment and Possible Removal of Discharge: We request an
explanation of the methodology and procedures that generated a classification of
Stewarts Creek as an impaired stream. The stream segment of Stewarts Creek that
might be impacted by out WTP discharge is very short, and we wish to make sure
this classification is accurate. Your cover letter that accompanied the draft permit
mentions removal of the discharge from the receiving waters if water quality does
not improve. Any required removal of the WTP discharge from its current location
and configuration would be very costly and burdensome to our staff and customers.
• Please provide the procedures by which any permit monitoring or limit parameter
can be reduced or removed. Due to the costs and impacts of the permit changes,
we will want to pursue this at the earliest possible date.
We appreciate the opportunity to comment on this draft permit. While we are very good
stewards of our operations and the environment, the continued increases in stringency we
see on all permits that we are receiving and/or renewing is creating a large impact on our
customers and staff. We respectfully ask that this be considered in this and future permit
actions.
Please call me if needed.

Dear Mrs. Sprinkle:
RECEIVED
AUG - 5 2008
DENR - WATER QUALITY
POINT SOURCE BRANCH
Please find enclosed in triplicate an application for renewal of NPDES Permit No. NCO080381 for the discharge
of treated basin sludge and backwash water from a water treatment plant process to the waters of Stewarts Creek
in Union County. This application is being submitted in advance of the 180 days required to the expiration of
the existing permit on January 31, 2009.
We are requesting that you review the enclosed application and renew our permit in accordance with the
requirements of state regulation.
The facility is not a primary industry under Title 40CFR, Appendix A; therefore no priority pollutant analysis is
required. The facility is an existing facility. We have installed since the last permit renewal a sulfur dioxide
dechlormation system consisting of a contact chamber with a''/2 HP submersible chemical mixer. Fiberglass
S02 Building that houses two (2) S02 cylinders, scale, sulfonators with auto switch over valves and sulfur
dioxide alarm system.
Please do not hesitate to contact me at any time during the review process at [phone] if you have any
questions.
Respectfully,
Russell G. Colbath P.E.

7. Describe the treatment process(es) for the raw water:
Aeration, Floculation, coagulation, sedmintation and filtration. In Lake Twitty we find
our first treatment process, aeration. From there the water is pumped from our source
water intake into the reaction basin. Potassium permanganate is injected into the water
prior to the reaction basin. Sodium hydroxide may be added prior to the reaction basin to
provide -alkalinity to the source water for treatment when needed. From the reaction
basin the water flows to our splitter box. Carbon is added between the reaction basin and
the splatter box. Sodium hydroxide is added right before the splitter box for pH control
and alkalinity adjustment. Ferric Chloride is added in the splitter box and is our primary
coagulant. From the splitter box the water flows to the individual rapid mixers where it
receives mechanical mixing. We have the capability to add our primary coagulant here
also. Polymer may be added to the discharge of the rapid mixers to assist in the
flocculation/ coagulation process.
From the rapid mixers the water flows into our flocculators where slow mixing of the
water and chemicals occur for floc formation. The water exits the flocculators directly
into the sedimentation basins. In the basins the heavier particles settle to the bottom of
the basin where they are removed by a Trac Vac system and sent to the sludge thickener.
The clear water from the top of the basins is sent to the filters. The filters are dual media
dual cell filters. The filters are rated at 4.5 mgd each. The objective of the filters is to
remove any suspended particles. In the filters we add chlorine, and sodium hydroxide,
polymer may be added here as well. The filters have an air scouring system for
backwashing. The back wash water is sent to the sludge storage lagoon.
From the filters the water is sent to the 2 million -gallon clearwell for further disinfection
prior to being sent to the distribution system.
S. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
The waste water from our facility is from ferric sludge and filter'back washes.Filter
backwash water is sent to the sludge storage lagoon where the solids settle out and the
supernatant is sent to the clarifier. The clarifier also accepts the settled solids from the
sedimentation basins either from the trac vac system or a basin dump. In the sludge
thickener the solids continue to settle to the bottom and thickening. The sludge is drawn
off the bottom and dispersed to the drying beds for drying or to tracks for land
application. The supernatant from the sludge thickener is de -chlorinated with sulfur
dioxide and discharge to the creek through the NPDES permitted discharge point.

Sludge Management Plan
John Glenn Water Treatment Plant
City of Monroe, North Carolina 7.3 d Q
Wastewater from the water treatment process consists of backwash water from the filters and
ferric chloride sludge removed from the sedimentation basins.
The backwash water from the filters is discharged to the sludge storage lagoon. In the sludge
storage lagoon solids from the backwash settle to the bottom. The clear water on the top is then
pumped to our clarifier by our sludge storage lagoon decant pumps.
Ferric chloride sludge from the sedimentation basins is discharged to the clarifier by routine
operation of the trac vac system or during periodic basin cleaning.
In the clarifier the solids and water are separated. The solids are concentrated in the bottom of
the clarifier and pumped to the drying beds or to tucks for land application. During the pumping
process the sludge being pumped to the drying beds is condition with polymer at the sludge
pumps. All sludge island applied in accordance with Land Application Permit No. W00001346.
The clear water from the top of the clarifier is discharged at controlled intervals by the decant
pumping station or gravity feed through the parshall flume where it is metered, from there it
flows through the dechlorination contact chamber into Stewarts Creek.
