requirements. The Facility Class II defines the minimum operator classification that is required for this facility
which this facility is currently meeting. This letter is a technical correction notification and we request that you
please attached it to the NPDES permit cover letter.
If you have any questions concerning this permit technical correction, please contact Ron Berry at

*Stream segment reclassified as C, HQW in December 2010
BACKGROUND
The Town of Lansing operates a 0.05 MGD wastewater treatment facility that serves the Lansing
community, population 150. The current Lansing WWTP facility began operation in 1989 and
discharges treated 100% domestic wastewater into Big Horse Creek. In December 2010 this
segment of Big Horse Creek was reclassified as C, HQW water in the New River Basin. Big
Horse Creek was classified as C, Trout, HQW water prior to this reclassification.
Untreated domestic wastewater enters the plant headworks where it flows across a manual bar
screen and collects in a sump. A composite sampler collects influent samples from the well.
Pumps then transfer the wastewater to the aeration basin where blowers provide the aeration. The
wastewater then continues to a clarifier module. The liquid continues from the clarifier, through
a tablet chlorinator, through a chlorine contact chamber, and through a tablet dechlorinator. The
treated wastewater flows through a flow weir. with records effluent flow volumes and is then
discharged into Big Horse Creek. An effluent composite sampler collects samples after the
meter.
When needed the clarifier cones are backwashed and diverted to the aerobic sludge digester. As
needed the sludge in the digester is dewatered and hauled by a contractor to Jefferson WWTP for
disposal. The Region has noted that this type clarifier system may not be as efficient at
maximum permitted flow conditions.
There have been some historical problems with undersized and/or poor performing blowers for
the aeration basin but they were resolved.

NPDES NC0066028

HISTORY
Level B models were conducted for this permitted discharge based on a stream class C and
supported secondary treatment standards (designated by the model as water quality limiting) for
BOD, TSS, and pH with no additional limits on ammonia or dissolved oxygen. The secondary
standard to meet 85% removal of TSS and BOD was also implemented at some point, at or
before 2001.
Instream and effluent monitoring for fecal coliform was required in 1996. Fecal limits were
added in 2001 based on the impact to the receiving stream, compliance was deferred for one
year. The instream focal monitoring requirement was removed in 2006 as it'did not apply. The
TRC limit was also added in the 2001 permit and compliance was deferred for one year. The
installation date of the tablet dechlorination system is unknown.
The ammonia toxicity was evaluated in 1988 and the Division detennined no ammonia limits
were required but ammonia monitoring was required. No WET testing was required.
COMPLIANCE
Since 2006 several incidences of unreported and/or missing DMR data did occur but were
reconciled with the Regional Office. The fecal coliform limits were exceeded on several
occasions in late 2009 and early 2010. No fines were accessed.

TRC, Fecal Coliform Compliance and Ammonia Toxicity
A narrative footnote defining the measurement reporting and compliance protocol for TRC will
be added to this permit. Rechecked the IWC % impact on TRC limit, Fecal Coliform limits, and
ammonia toxicity monitoring and confirmed existing permit requirements remain valid.
Receiving Stream Reclassification
The reclassification of the receiving stream removed the Trout designation. Based on WQS the
dissolved oxygen minimum standard is reduced to 5.0 mg/l as compared to the Trout
classification of 6.0 mg/l. This does not affect any of the facility existing permit requirements.
HQW Rules
This facility meets existing permitting criteria. However, if this facility ever expands or replaces
this treatment works, the ,HQW rules for new/expanding facilities will apply.

Contacted George Smith, WSR inspector, to discuss the February 2011 inspection report. Pes
Mr. Smith there are no issues and he recommends we update the component list narrative.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies the following will be incorporated into the permit:
• A new TRC footnote narrative will be added to define the reporting and measurement
protocols.
• The supplemental page treatment component description will be updated to include all
significant items.
• The receiving stream narratives will be updated to list the stream December 2010
reclassification designation.
• The physical facility address will be corrected.
• Facility class was corrected to Class /b

Thanks for returning my call. I regret I made an error in the original email address, that is why you did
not see it. I made a new google-based map for your review using the information you provided. There is
still some discrepancy in the address but it may because of google . If you could please confirm which

George,
I am working on the Lansing WWTP NPDES renewal and noted you had just completed an
inspection.
Per notes in BIMS you stated "They are not using a dechlorination unit at this
time" is this an issue? Do
you have any other NPDES issues or concerns? Three basic corrections have been
determined for this
renewal so far:
1) This segment of Big Horse creek was reclassified in Dec 2010 to just C, HQw.
will only be a
narrative correction and does not effect permit requirements.
2) The physical plant address will be corrected to 3322 Teaberry Road. This is
only a narrative
correction.
3) The component list on the Supplemental page will be expanded to list all
components.

Town of Lansing WWTP
Sludge Management Plan
The Town of Lansing wastes sludge from its aeration basin to an aerobic digester. The digester
is dewatered at regular intervals by means of an airlift unit as well as a portable pump with a 2
inch discharge. The supernatant is returned to the aeration basin.
The town contracts the hauling of the thickened sludge to Doug Cox Backhoe Service. The
sludge is hauled by a 3000 gallon vacuum truck to the Jefferson Wastewater Treatment Plant.
