A. (2.) CHRONIC TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 90%. The testing shall be
performed as a Ceriodaphnia dubia May pass/fail test. The tests will be performed during the months of
January, April, July and October. Effluent sampling for this testing shall be performed at the NPDES
Permitted final effluent discharge below all treatment processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWR Form AT-1(original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 and accurate and include all supporting chemical/physical measurements performed
in association with the toxicity tests, as well as all dose/response data. 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.
"No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences
Section at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
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.
If the Permittee monitors any pollutant more frequently then required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.
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.

Permit NC0080381
A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)

1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)1
Beginning no later than 270 days from the effective date of this permit, the permittee shall begin
reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge
Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements may
be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3)
or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above.
Requests for temporary waivers from the NPDES electronic reporting requirements must be
submitted in writing to the Division for written approval at least sixty (60) days prior to the date the
facility would be required under this permit to begin using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.

Re: Application for Permit Renewal a heritage of progress
NPDES Permit NC0080381
City of Monroe John Glenn Water Treatment Plant
Stewarts Creek — Yadkin/Pee Dee Basin
Union County
Dear Mr. Weaver:
Please find enclosed in triplicate an application for renewal of NPDES Permit No. NC0080381 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, 2014.
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 replaced the 2 progressive cavity sludge
pumps with 2 variable speed positive displacement rotary lobe pumps and replaced the mechanism for the
sludge thickener since the last permit renewal.
Please do not hesitate to contact me at any time during the review process at [phone] if you have
any questions.
Respectfully, C /�-

6. Description of source water(s) (i.e. groundwater, surface water)
Surface Water
7. Describe the treatment process(es) for the raw water:
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 seasonally as needed 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 splitter 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 or during a basin dump through bottom drains and sent to the clarifier (sludge
thickener). The clear water from the top of the basins is sent to the fitters. The filters are dual media dual cell filters. The filters are
rated at 4.5 mgd each. The objective of the fitters 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 ba kwashing. The back wash water is
sent to the sludge storage lagoon. The fiflered water flows to the 2 million -gallon clearwell for further disinfection prior to being sent
to the distribution system
8. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
Filter backwash water is sent to the sludge storage lagoon where the solids settle out and the supernatant is sent to the clarifier
(sludge thickener). 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 trucks for land application. The supernatant from the sludge thickener is de -
chlorinated as needed with sulfur dioxide and discharge to the creek through the NPDES permitted discharge point.

Solids Handling Plan
John Glenn Water Treatment Plant
City of Monroe, North Carolina
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 wash water lagoon. In the wash lagoon solids
from the backwash settle to the bottom. The clear water on the top is then pumped to our clarifier (sludge
thickener) by our wash water 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 sand drying beds or to trucks for land application. During the pumping process to
the drying beds the sludge is condition with polymer at the sludge pumping pumps. The dewatered cake
from the sand drying beds is currently taken to the City of Monroe's'wastewater plant where it is blended
with their sludge and land 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.
