Re: NPDES Permit Renewal Application
McDowell Creek WRRF — NPDES Permit #NC0036277
Mr. Montebello:
RECEIVED
JAN OIL 2024
NMEQIDWRINPOES
Please find the enclosed NPDES permit renewal application for McDowell Creek WRRF. The application
includes Attachments #1-10. The following is a summary of the attachments submitted with the
application:
• Attachment #1 is a narrative description of McDowell's treatment process.
• Attachment #2 provides additional information requested in Section 1.6. Inadequate space
was available to record 'Other' environmental permits.
• Attachment #3 summarizes the contractor information requested in Section 1.25.
• Attachment #4 addresses Section 2.2 and explains the ongoing work that CLTWater does to
minimize inflow and infiltration.
• Attachment #5 includes the topographical map required in Section 2.3.
• Attachment #6 includes the plant flow schematic required in Section 2.4.
• Attachment #7 provides the scheduled improvements as requested in Sections 2.5 and 2.6.
• The data in Table A is summarized for the time period of March 2022 through October 2023.
• For Table 8, all parameters are summarized from March 2022 through October 2023 except
for TRC, Oil and grease, and TDS. Since these parameters are a part of the annual Effluent
Pollutant Scan, they were summarized for the past 4.5 years (May 2019 through October
2023), in order to provide a larger data set for these parameters.
• For Table C, annual Effluent Pollutant Scan parameters results were also provided for the
past 4.5 years (May 2019 through October 2023). These are easily recognizable since they
are represented by only 5 data points. All the other parameters listed in Table C were
summarized using the time period from March 2022 through October 2023.

,46 Operated by the City of Charlotte

• For Table D, to the best of our knowledge, no additional parameters covered under 40 CFR
Part 136 have been sampled at our influent or effluent that have not already been reported
to NCDWR via the eDMR process. Given that CLTWater has no additional data to report,
CLTWater did not complete the chemical addendum sheets set forth in Table D.
• Attachment #8 includes a list of current components to be included in the "Supplement to
the Permit Cover Sheet".
• Attachment #9 includes the Priority Pollutants Analysis reports with organics results that
have been completed by this facility since the last permit renewal.
• Attachment #10 includes information that supports CLTWater's request for continuation of
reduced monitoring frequencies for conventional pollutants.
Charlotte Water is in the process of updating ail Wastewater Treatment Plant (WWTP) facility names to
Water Resource Recovery Facilities (WRRF's). CLTWater is requesting that the name of McDowell Creek
WWTP be changed to "McDowell Creek WRRF" in the issuance of the draft and final permits.
Please note that some of the parameters for which data has been submitted in this application have two
method detection limits. This is due to a change in the sensitivity of the analytical method or a change
in the requirement to use a different analytical method and/or report to a lower detection limit during
this permit cycle.
Please let us know if you have any questions or if you need any further information. You may contact
Shannon Sypolt, Water Quality Program Administrator, at 704/634-6984 or Daniel Matias, ORC of
McDowell Creek WRRF, at 704/336-1125. You may also contact me at 704/634-3665. Thank you for
your assistance with the renewal process.

Attachment #1
McDowell Creek WRRF Narrative of Treatment Processes
McDowell Creek is a 12 MGD BNR WRRF.
Liquid Processes
Wastewater enters the plant through a 36-inch gravity sewer line and splits between two manholes.
Flow then enters the headworks and influent pumping station through two 48-inch gravity sewer lines.
Flow entering the headworks separates into two screening channels and passes through two %-inch
mechanical bar screens. The lift station maintains a pumping capacity of 50 MGD with the first stage lift
pumps. Screenings are compacted and conveyed to a dumpster loading area common with the grit
dumpsters. After screening, influent flow is routinely equalized through a 1.3 MG day tank. During
excessive rain/flow events, flow may be sent to a 12 MG storm equalization basin. Average daily flow to
the plant is 5.8 MGD.
From the day tank/storm EQ basins, flow is sent to two primary clarifiers with a combined volume of
500K gallons or 6 MGD of treatment capacity. Each primary clarifier feeds a Biological Treatment Basin
(BTB). The two biological treatment basins are a 5-stage Bardenpho Process Design with anaerobic,
anoxic, oxic, post -anoxic, and re -aeration zone to have optimal phosphorous, nitrate, and NH3 removal.
Each BTB has treatment design of 3 MGD and a volume of 1.57 MG. Flow leaving the BTBs is sent to
three 1 MG final clarifiers for secondary treatment.
Combined secondary effluent from all the final clarifiers is sent to the deep bed sand filters (EF-1 and EF-
2) for filtration and UV disinfection. Post UV disinfection, flow can be sent to membrane filtration units
for additional treatment if necessary. Filtered effluent from the membrane filtration system and the
effluent filter structures will be combined and sent to the cascade aeration structure where re -aeration
takes place. The cascade aeration structure will discharge through a 48" line into McDowell Creek.
The plant effluent discharges to McDowell Creek, which flows into McDowell Cove, which then flows
into the Catawba River and Mountain Island Lake.
Solids Processing and Biosolids Management at McDowell Creek WWTP
McDowell Creek WRRF operates primary digesters with an average detention time of 30-40
days. The average total solids content of the sludge (RAW and TWAS) being sent to the primary digester
is 3.0 - 4.0%. Average sludge flow to the primary digesters is between 40-50k gallons/day. McDowell
Creek WRRF is currently operating one secondary digester with a volume of 480k gallons. The average
total percent solids for the digested sludge at McDowell Creek WRRF is 1.5 - 2.0%. For thickening and
dewatering purposes, McDowell Creek WRRF uses two 1.5-meter gravity belt thickeners and two 2-
meter belt filter presses. Dewatered solids are belt conveyed out of the dewatering building onto a
covered storage pad onsite. They are stored here before being hauled off.

The average cake material is 13% solids. All biosolids produced at McDowell Creek WRRF are Class B
and are land applied in both North and South Carolina (if they pass all required testing and conform to
40 CFR Part 503). All non -conforming solids are landfilled.

Inflow and Infiltration (1&1) Reduction Practices
Charlotte Water has maintained an established evaluation and rehabilitation program since the early
1990's. The purpose of this program is to restore and preserve hydraulic capacity, structural integrity,
and to reduce corrective maintenance costs by addressing issues that cause SSOs. This includes
maintaining and implementing an on -going 1/1 reduction plan.
Multiple construction contracts are continually in place to address these issues. Through comprehensive
SSES efforts, including manhole inspections, smoke testing, CCTV, flow monitoring, etc., areas are
identified for rehabilitation and work orders assigned to a contractor. The work may include manhole
rehabilitation, point repairs, pipe lining and pipe replacement.
Charlotte Water uses flow monitoring extensively tc

addition, flow monitoring provides sewer flow data
validation. We currently have 56 permanent flow

Since 2018, Charlotte Water's Sanitary Sewer Rehab Program has inspected 6,600 manholes, and
performed CCTV inspection and cleaning on 7,950 ft. of pipe, resulting in the following; 22 manholes
rehabbed/repaired, 1 inflow dish installed, 6 cleanouts repaired/replaced, and 7,540 ft. of pipe
rehabbed/replaced throughout the McDowell collection system. This does not include similar work
performed by Charlotte Water's Field Operation Division.
