NPDES Permit Renewal Application Submittal
Mr. Montebello,
The Town of Spruce Pine hereby requests renewal of NPDES Permit
NC0021423 for the Spruce Pine WWTP.
Enclosed please find the original and two copies of the Town of Spruce
Pine NPDES Permit Renewal Application. As required by NCDEQ
beginning February 1, 2020, the new EPA NPDES Permit Application
form was used for the submittal.
Please note the following regarding the NPDES Permit Renewal
Application:
■ The Town of Spruce Pine has a Modified Pretreatment Program. As
such, they were required to develop a "Short Term Monitoring
Plan" (STMP) that only required 4 samples be taken in the year
prior to the submittal of the Headworks Analysis (HWA). The data
submitted on Table C includes the STMP data as well as data from
4 Effluent Pollutant Scans (PPA). The May 2020 STMP data was
also a PPA sampling event, resulting in 7 data points for certain
parameters.
• The Town conducted PPAs in the following calendar years: 2016,
2017, 2019, and 2020 as per the current NDPES permit.
• The STMP sampling was conducted from July 1, 2019 through
June 30, 2020. The data generated in this 12-month period was
also used for this NPDES Permit renewal application. The Town
conducted 4 chronic Whole Effluent Toxicity (Ceriodaphnia) tests
during this time frame (using 6.6% effluent) and all 4 tests passed.
Post Office Box 189,Spruce Pine,North Carolina 28777-0189
Telephone: [phone] Fax: [phone] Website: www.sprucepine-nc.gov

This is the same time period used for the recent Town of Spruce
Pine HWA submittal. The Town had no NPDES Permit violations
during this period.
■ The town conducted 24 WET samples during the last 5 years (20
chronic WET tests using daphnia and 4 second species WET using
fat head minnows). The Town passed all 24 WET tests. A
summary of all WET tests is included as 2 separate spreadsheets.
■ Although the Town conducted seven effluent mercury analyses
during the last 4.5 years, only three of the analyses were
conducted using EPA Method 1631 (low-level). The results of the
three 3 low-level analyses were reported on Table C. The other 4
results using EPA Method 245.1 were <0.0002 ug/1.
■ As mentioned in the HWA submittal, during an EPA/NCDEQ
inspection in December 2015 it was discovered that the effluent
weir and associated effluent flow meter had been calibrated
incorrectly (by a contractor) for a period of years. The Town of
Spruce Pine had the weir/meter calibration corrected within 48
hours of being made aware of the issue. This explains the
significant flow increase included in the current NPDES permit
renewal submittal.
■ Several parameters had different PQLs/MLs during the reporting
period. The lowest PQL reported was listed on Table C.
■ Zero was used for Below Detection Limit (BDL) values in
calculating averages on Tables A, B, and C, as per the NCDEQ
policy for eMDRs.
■ We regret that the NPDES Permit application was delayed due to
Town Manager personnel changes and Covid.
Please feel free to contact me at managerna,sprucepine-nc.gov.

Town of Spruce Pine Wastewater Treatment Facility Overview
Process Control Management Plan June 2020
Veolia North America M&C
History
The Spruce Pine waste plant has been around a long time. It has experienced a few upgrades.
The latest was in 1998. The plant was converted from activated sludge and anaerobic digestion
to and oxidation ditch and aerobic digestion. The capacity was increased to a max of 2 million
gallons per day.
Wastewater generated from residences and business in Spruce Pine and Ledger is conveyed to
the treatment plant through a network of collection system piping and 14 lift stations. The
plant currently treats an average of 800,000 gallons per day. During rain events however the
plant receives as much as 3 million gallons from water runoff. The wastewater is treated
through a biological treatment process. It results in a high quality discharge that has minimal
impact on the Delayed Harvest trout stream it discharges to.
Preliminary Treatment
The first phase of the waste plant the flow goes through a MN step screen. This screen was
installed new in 2019. It is a model 5000-500-6. It has % inch space between bars. The bars are
1/8 inch in thickness. This screen is capable of running by level, time or manually. There is a
wash press that is attached to the bar screen. Then the screenings are pushed through a shoot
into a dumpster. When the dumpster is full the screenings are picked up and hauled off by GDS
incorporated.
The next place the flow enters is into the wet well where the influent pumps reside. We have
two Flygt 3171 non clog pumps. They were installed new in 2019 also. They are 34 HP each.
They are capable of pumping 1355 gallons at a head of 61 feet. Our head is currently 65 feet.
These pumps are 1755 rpm and 460 volts. They can pull up to 40 amps.
The influent pumps then pump all the flow to the Eutek Teacup Solids Classifier. It is 72 inches
in diameter. This is supposed to remove 95% of all grit at 1 million gallons per day. It is
designed for 2 million gallons per day flow. The peak flow is 5 million gallons per day. It works
similar to washing machine. The flow is spun around the unit and the inorganics fall out to the
bottom. They are then sent to a dumpster to settle. When the dumpster is full GDS
incorporated picks it up and hauls it off.

Biological Treatment
After preliminary treatment the flow enters into an Orbal oxidation ditch. The ditch is 137 feet
wide and 182 feet long. It has three rings total and holds 2 million gallons. There are two 30HP
motors on the inside rings and four 40HP motors on the outside rings. These motors turn
shafts with mechanical discs to add oxygen to the waste water by being submersed in the
liquid. The process is designed to have optimal dissolved oxygen at 0 on the 1st ring, 1 on the
2nd ring and 2 on the third ring. Our staff manually runs the rollers to achieve the DO's as
recommended. This ditch is designed to keep a directional velocity to keep the solids in 1
suspension. Orbal plants can remove 98-99 percent of the BOD. Channel one is considered
1 the work channel. Channel two is considered the swing channel. Channel three is considered 1
exits the ditch and heads for the next step the polishingchannel. The third channel p of our
process. The oxidation ditch is designed to have a MLSS concentration from 3000 to 6000 mg/I.

Final Clarification
When the flow leaves the center ring of the oxidation ditch it comes to the splitter box. The
splitter box has three adjustable gates. One gate controls each clarifier. We have two big ones
that are used regularly. They are approximately 265,000 gallons. We have one smaller one
that is used for emergencies only. It is approximately 115,000 gallons. The solids settle to form
blankets and the clear water on the top flows over the weir and goes to the next step of
treatment.

Chlorination/Dechlorination/Final Effluent discharge
Next the flow goes to the chlorine contact chamber. This is a round tank that holds
approximately 46,000 gallons. It slowly works its way through each train after being injected
with chlorine gas at the front end. This provides detention time to kill all the pathogens. Then
the flow leaves the chlorine tank and goes into the dechlorination basin. Here it is injected with
sulfur dioxide gas to take the chlorine out of the water for discharge to the river. The chlorine
and sulfur dioxide feed is flow proportional.

Chlorine contact basin is located to the right. Dechlorination contact basin is located to the left.
These were converted to what they are now in 1998.
Solids Handling
Solids are wasted as needed out of the process into two aerobic digesters. Each one is 195,000
gallons. Three 40HP roots blowers add air to this process. One side has one common header
that provides air. We use this side to thicken the solids to pump over to the other side. In 2003
the other side was upgraded to coarse bubble diffusers. This provides much better mixing. It
also has a floating mixer on the end where it leaves this process and heads to the belt press.
We have a 1 meter Asbrook belt press. The building and the press was built in 2009 after many
years of liquid land application failed to remove enough solids from the process. Now the press
cake is removed by being hauled to Irish Glen Landfill in Johnson City TN.
