Compliance Sampling Inspection
Lake Norman Woods WWTP
NPDES Permit No. NCO071528
Catawba County
Tracking #: NOV-2018-PC-0415
Dear Mr Norman:
Enclosed is a copy of the Compliance Evaluation Inspection Report for the inspection conducted at the subject facility on
October 25, 2018, by Mr. Wes Bell of this Office. Please inform the facility's Operator -in -Responsible Charge (ORC) of our
findings by forwarding a copy of the enclosed report. The results of the effluent samples collected during the inspection will
be forwarded to you under separate cover.
This report is being issued as a Notice of Violation (NOV) due to the following failures to provide proper operation and
maintenance:
1) Holes were observed in the metal support structure along the aeration basin and aerated sludge holding tank;
2) The visual and audible alarm system (high water) for the equalization basin was not operational;
3) A severe leakage was observed in the return activated sludge (RAS) piping system;
4) Clarifier weirs were deteriorated with some being bent with uneven flow distribution;
5) Standby power generator was not operational.

dollars ($25,000.00), or twenty-five thousand dollars ($25,000.00) per day when the violation is of a continuing nature,
against any person who violates or fails to act in accordance with the terms, conditions, or requirements of any permit issued
pursuant to G.S. 143-215.1. Penalties may also be assessed for any damage to surface waters of the State that may result from
the violation.
It is requested that a written response be submitted to this Office by November 30, 2018, detailing the actions taken to

On -site Representatives:
The following Envirolink, Inc. personnel were in attendance during the inspection: Mr. Chris Bitterman,
Mr. Chip White, and Mr. Dennis Murdock.
OPERATIONS & MAINTENANCE SECTION cont'd:
Overall, the wastewater treatment facility appeared to be adequately treating wastewater at the time of
the inspection; however, operation and maintenance issues were noted with the facility's metal
structure, equalization basin alarm system, clarifier weirs, and standby generator. See Equalization
Basin, Aeration Basin, Secondary Clarifier, and Standby Generator Sections for additional comments.
Please be advised that the subject permit requires the permittee to properly operate and maintain the
facilityall facilities and systems of treatment and control at all times [Permit Condition Reference: Part
II, Section C(2) Proper Operation & Maintenance]
Note: The structural integrity concerns and the operation/maintenance of the equalization basin alarm
system, clarifier weirs,and standby generator were noted in the previous inspection report (Notice of
Deficiency) dated 4/17/17. In addition, the permittee's response to the inspection report (dated 5/4/17)
indicated that corrective actions would be completed by a contracted company (Kemp, Inc.) to address
the structural integrity concerns along with repairs to the clarifier weirs, equalization basin alarms, and
standby generator.

(during the inspection) at 13.1 mg/L (DO), 7.14 SU (pH), 11.5 degrees Celsius
(temperature), and <10 ug/L (total residual chlorine). In addition, DWR staff collected
effluent BOD, TSS, ammonia, fecal coliform, total nitrogen and total phosphorus samples
during the inspection. The results of these effluent samples will be forwarded under

Comment: The facilitv is eauiDDed with an aerated sludae holdina tank. A contracted comoanv (Lake
Norman Sewer & Septic) removes wastewater solids on an as -needed basis. Usage of the
sludge holding tank has continued to be limited due the structural integrity concerns (holes,
severe corrosion/rust) in the metal support wall that connects with the influent piping
system/flow diversion box..

Comment: The backup generator was not operational at the time of the inspection. In addition, the
current wastewater operations staff were not familiar with the operation/testing of the
generator. A copy of all maintenance activities and testing events should be kept at the
WWTP site (mailbox inside the fence) for review by wastewater staff and DWR personnel.
The permittee should also provide a copy of the operation manual to the wastewater staff.
