The Tuckaseigee Water and Sewer Authority currently owns and operates three (3) wastewater
treatment facilities and has contracted to operate the Whittier WWTP for the Whittier Sanitary
District.. The following report is a summary of the operation of these facilities for the 2012
calendar year.

Air Permit #08420R01
ffrlmwate�°-pff �C 110�1
TWSA Plant # 1 discharges from one outfall into the Tuckasegee River which is classified Class
C-Trout waters in the Little Tennessee River Basin. The plant design process is a sequencing
batch reactor (SBR) version of the activated sludge process with a design capacity of 3.5 million
gallon/day. The plant consists of the following unit processes, automatic band screen, vortex grit
removal,150 hp triplex influent pump station, 2 SBR basins with a capacity of 1.694 mg each,
.468 mg gal of flow equalization, .1508 mg gals of chlorination capacity and d-chlorination and
reaeration facilities.
The TWSA completed the plant upgrade in 2011 and is currently operating well within permit
limits. The expansion should help to meet the growing needs of the county well into the future.
(page 1)

In addition the plant continues to treat wastes generated by septic tank pumpers in Jackson
County as well as portable toilet services provided during construction of any homes or
businesses in the County. These services to the total geographic area of the county significantly
impact the facilities sludge management operations.
Overall performance of the plant was excellent during 2012. A new chemical feed building was
constructed during 2012 and is operating as designed. The new sludge dryer is operating and the
costs to dry sludge have been less than expected. This new system allows staff to remove sludge
from the process regardless of the weather and greatly enhances the ability of the staff to
properly operate the plant.
The average daily flow at the facility during the year 2012 was 0.761 mgd. This represents
21.7% of plant permitted capacity and was a 3.8% decrease from 2011. The highest monthly
average occurred in March and April was recorded as 0.879 mgd. This represents 25.1% of total
plant capacity and was a 13.4% decrease from 2011. The highest daily recorded flow in 2012
was 1.541 mgd and occurred Oct 3rd, 2012. This represented 44.0% of total plant capacity and
was an increase of 3.4% from 2012. There were zero (0) days in 2012 when the recorded flow
was greater than plant capacity. The facility had one month in 2012 when it exceeded permitted
values. A malfunctioning influent valve on the #2 SBR resulted in discharge of water with higher
than permitted values for BOD (biochemical oxygen demand) in the month of February 2012.
Total sludge production was calculated from the amount of sludge processed on the belt filter
press. These residuals totaled 2,119,736 gals of sludge and were calculated at 170.91 dry metric
tons. This represents all of the sludge generated by the Authority's facilities during 2012. When
the sludge production of the other plants the Authority operates is subtracted from this total, it is
estimated that the TWSA Plant #1 facility produced 138.98 dry metric tons of sludge during
2012. This is 81.3% of the total amount of sludge produced by the facilities operated by the
Authority during 2012. This sludge is dried to meet EPA and NCDENR regulations and is made
available for distribution to the public as a soil amendment. Approx. 81 tons of residuals were
disposed of in this manner during 2012. Another 24.8 tons was hauled by a private contractor to
a land fill in GA for disposal.
The following is a summary of violations that occurred during 2012.

TWSA Plant # 2 is operated under the authority of the following permit, as issued by the North
Carolina Dept. Of Environment and Natural Resources: NC0020214 NPDES Discharge Permit
TWSA Plant # 2 discharges from one outfall into Scott Creek which is classified Class C-Trout
waters in the Little Tennessee River Basin. The plant process is a conventional activated sludge
process with a design capacity of 0.5 million gallon/day. The plant consists of the following unit
processes, manually cleaned bar screen, aerated grit removal, activated sludge with secondary
clarification and chlorination and dechlorination facilities. The addition of a surge (ec) basin is
needed to maximize the treatment capacity of the plant. As of Dec 31", 2012 the main concern at
this facility is the outdated and mismatched electrical facilities. The electrical facilities will have
to be substantially upgraded to allow the Authority to move forward with any plant
improvements.
The average daily flow at the facility during the year 2012 was .199 mgd. This represents
39.8 % of plant capacity and was a 0.5 % decrease from the avg. daily flow last year. The
highest monthly average occurred in April and was recorded as .262 mgd. This represents
52.4% of total plant capacity and was a 6.4% decrease from 2011. The highest daily recorded
flow in 2012 was .629 mgd and occurred May 14th, 2012. This represented 125.8% of total
plant capacity. There were four (4) days in 2012 when the recorded flow was greater than plant
capacity. The same number of days as 2010 and 2011.
This plant produced 343,200 gallons of waste sludge during 2012. This sludge was hauled to
TWSA Plant #1 for treatment. These residuals totaled 25.33 dry metric tons and represented
14.8 % of the total residuals generated by the Authorities facilities.
Overall performance of the TWSA #2 wastewater plant for the calendar year of 2012 was
excellent with no violations of monthly parameters as specified in the permit.
The permit for this facility was renewed in 2012 and will expire on October 31, 2017.

which' is classified as Class B-Trout ORW waters in the Savannah River Basin. The plant process
is a conventional activated sludge process with a design capacity of 0.2 million gallon/day. The
plant consists of the following unit processes, manually cleaned bar screen, extended air
activated sludge with secondary clarification, tertiary filters and chlorination and dechlorination
facilities. The addition of a band screen at the headworks would greatly improve operations and
the quality of sludge the plant produced.
The average daily flow at the facility during the year 2012 was .073 mgd this represents 36.5%
— of plant capacity and represents a 15.1 % increase in avg daily flow from 2011. The highest
monthly average occurred in July and was recorded as .112 mgd. This represents 56% of total
plant capacity and represents a 31.2% increase from 2011. The highest daily recorded flow in
2012 was .190 mgd and occurred April 18th, 2012. This represented 95% of total plant capacity
and was a 10.4% decrease from 2012. There were zero (0) days in 2012 when the recorded flow
was greater than the plant capacity as compared to one (1) days in 2011.
This plant produced approx 75,000 gallons of waste sludge during 2012. This sludge was hauled
to TWSA Plant #1 for treatment. These residuals totaled 6.60 dry metric tons and represented
3.9 % ;of the total residuals generated by the Authorities facilities.
Overall performance of the TWSA #3 wastewater plant for the calendar year of 2012 was
excellent with no violations of any monthly permitted parameters.

The Whittier Sanitary District currently contracts operation and maintenance of the Whittier
WWTP to the Tuckaseigee Water and Sewer Authority.
Whittier WWTP is operated under the authority of the following permit, as issued by the North
Carolina Dept. Of Environment and Natural Resources: NC0087602 NPDES Discharge Permit
The Whittier WWTP discharges from one outfall into the Tuckaseegee River which is in the
Little Tennessee River Basin. The plant process is a conventional activated sludge process with a
design capacity of 0.1 million gallon/day. The plant consists of the following unit processes,
influent pump station, manually cleaned bar screen, extended air activated sludge with secondary
clarification, tertiary filters and ultra -violet light disinfection facilities.
The average daily flow at the facility during the year 2012 was .005 mgd this represents 5% of
plant capacity and is the same daily flow avg as recorded in 2011. The highest monthly average
occurred in August and was recorded as .007 mgd. This represents 7% of total plant capacity.
The highest daily recorded flow in 2012 was .042 mgd and occurred Jan 24th, 2012. This
represented 42% of total plant capacity and was a 6.7% decrease from 2011. There were zero
(0) days in 2012 when the recorded flow was greater than plant capacity. This is a new plant and
as such there is very little daily flow to be treated. This poses unique operational problems and
results in difficulty in keeping a viable population of bacteria alive to treat the incoming waste
with. The plant is currently being batch operated, with a discharge occurring just on the days
needed.
Overall performance of the Whittier wastewater plant for the calendar year of 2012 was excellent
with no violations of monthly parameters as specified in the permit.
The permit for this facility was renewed in 2012 and will expire on Oct 3Is, 2017.
