consider all effluent TRC values reported < 50 µg/L to be in compliance with the permit. However, the
Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory
(including field certified), even if these values fall below 50 µg/L.
3. Chronic Toxicity (Ceriodaphnial, P/F, 6%; January, April, July and October; See Part A. (2.).

The permit holder shall perform at a minimum, civarterlu monitoring using test procedures outlined in the "North Carolina
Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions or "North Carolina
Phase II Chronic Whole Effluent Toxicity Test Procedure"I (Revised -February 1998) or subsequent versions. 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.
If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit
limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months
as described in "North Carolina Phase IL Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998)
or subsequent versions.
The chronic value for multiple concentration tests will be determined using the geometric mean of the highest
concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a
detectable impairment of reproduction or survival:' The definition of "detectable impairment," collection methods, exposure
regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test
Procedure" (Revised -February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring
Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and
THP3B for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the following address:

Should the permittee fail to -monitor during a month in which toxicity monitoring is required, monitoring will be required
during the following month.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality
indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate
monitoring requirements or limits.
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.

BACKGROUND
The Town of Maggie Valley WWTP is a 1.0-MGD plant serving the Town of Maggie
Valley and Jonathan's Creek, a total population of approximately 2000. The wasteflow
at this facility is entirely domestic, so Maggie Valley has no pretreatment program.
The facility discharges to Jonathan's Creek in the French Broad River Basin; these
waters are classified C-Trout.
Waste Load Allocation (WLA). The Division prepared the last WLA in 1996. The
previous and current effluent limits were based on guidelines and water quality
standards. The Division has judged previous parameters and limits to be appropriate
for renewal.
TOXICITY TESTING
Current requirements: At 1.0 MGD, Chronic toxicity P/F at 6.0%: Jan Apr Jul Oct.
A review of submitted chronic Ceriodaphnia toxicity tests shows that the facility has
passed all tests during the previous permit term.
Recommendation: Renew the existing chronic toxicity test @ 6.0%
COMPLIANCE SUMMARY
Facility has a good compliance history. During the previous permit term it received
only 1 Notice of Violation for not submitting the DMR (05/28/2008). The latest

Re: Town of Maggie Valley
Waste Water Treatment Plant Permit Renewal
Haywood County, North Carolina
Dear Mrs. Sprinkle:
WIN
[JUL 2 8 2010
Please find enclosed one signed original and two copies of the Discharge Permit
Application Form for the Waste Water Treatment Plant renewal of the Town of Maggie
Valley's existing permit #NC0056561.
The Town of Maggie Valley currently operates a 1.0-MGD wastewater treatment plant
(WWTP) and an alkaline sludge stabilization facility. The wastewater treatment facilities
include a mechanical influent bar screen, flow selector basin, 2 rectangular aeration
basins, 2 rectangular Aero-Mod clarifiers, dual aeration blowers for each aeration
basin/clarifier (five (5) blowers total), two (2) sludge holding basins, belt filter press,
chlorination, a chlorine contact basin, sulfur dioxide dechlorination, and effluent flow
monitoring. The alkaline sludge stabilization facility includes a lime kiln dust silo, a
volumetric lime kiln dust feeder, a sludge mixer/blender, and a concrete sludge drying/
storage pad. The stabilized sludge is stockpiled and offered to the public for beneficial
reuse applications.
The Maggie Valley facility added new equipment since issuance of the last permit. The
(3) dual aeration/clarifier basins were converted into two (2) aeration only basins.
The addition of a new selector basin and two (2) new rectangular clarifiers gives the
Maggie Valley facility the ability to consistently reduce our TSS and BOD
concentrations.

Maggie Valley WWTP Process Description: Flow enters the Maggie Valley WWTP
through an 12" gravity sewer line to the influent screening channel. The influent screen
is a step screen with 1/4" openings. The wastewater then flows to a selector basin which
acts to mix the raw influent and return activated sludge. This flow is then split to two
treatment trains. Each train consists of first stage and second stage aeration basins. The
first stage aeration basins are aerated by fine bubble diffusers and the second stage basins
are aerated with coarse bubble aeration. Second stage aeration cycles on and off to
promote denitrification prior to clarification. Following aeration the wastewater flows to
dual rectangular clarifiers with air lift RAS pumps. Clarified effluent is disinfected with
chlorine gas in the chlorine contact basin and dechlorinated by sulfur dioxide prior to
discharge to Jonathan Creek. Solids are wasted by duplex sludge wasting pumps to two
digesters. Solids are then pumped to a 1.0 meter belt filter press for dewatering and lime
stabilization to produce a class A-biosolid.
The Sludge Management Plan provides for residuals produced on site to be treated on site
by the Alkaline Stabilization Process. The residuals will be pumped from the digester
through the belt filter press and conveyed to the Alkaline Stabilization process
equipment. The processed material is placed in piles and monitored. The residuals are
then windrowed on a covered concrete pad for additional drying and conditioning. The
dried material is stockpiled on a portion of the pad until it is disbursed in bulk to area
farmers and landscape professionals. Also included you will find a Bio-solids Product
Information Guide.
The Town of Maggie Valley facility has begun receiving landfill leachate since issuance
of the last permit. The leachate is trucked and hauled to the Maggie Valley facility in
6,000 gallon loads. The leachate is unloaded at the headworks of the WWTP and is not
to exceed 50,000 gallons per day. Town of Maggie Valley staff assists and monitors
deliveries. The Town has consulted with DWQ staff regarding this acceptance and DWQ
has determined that this is not considered a significant industrial user and therefore would
not trigger a pre-treatment program requirement. The Town has a formal agreement to
accept the leachate which requires annual testing of the leachate and states that the Town
may refuse to accept the leachate at any point it wishes.
If you have any questions regarding the enclosed permit application renewal form or
information provided herein, please do not hesitate to contact me.
Sincerely,
Timothy Barth
Town Manager
