A. (2.) CHRONIC TOXICITY MONITORING (QRTRLY)
The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North
Carolina (Ceriodaphnia Dubia) Chronic Effluent Bioassay Procedure," Revised February 1998, or
subsequent versions.
The effluent concentration defined as treatment two in the procedure document is 5.78 %. The testing shall be
performed as a Cedodaphnia,dubia 7day pass/fail,test. 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.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWQ Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, N.C. 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no
later than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed
in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent
toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the
permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the
facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No
Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Section at
the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
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.
If the Permittee monitors any pollutant more frequently than required by this permit, the results of such
monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms
submitted.
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.

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
Samples are collected twice per month with at least ten calendar days between sampling events. These samples
shall be representative of the wastewater discharged during the sample period.
3/Week
Samples are collected three times per week on three separate calendar days. These samples shall be representative
of the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et.
seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
Bypass
The known diversion of waste streams from any portion of a treatment facility including the collection system,
which is not a designed or established or operating mode for the facility.
Calendar Day
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period.
The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour
period of discharge and combined proportional to the rate of flow measured at the time of individual
sample collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period
at a constant time interval. Use of this method requires prior approval by the Director. This method may
Version 1012912010

monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is
calculated as the total mass of the pollutant discharged over the day. The "daily discharge" concentration
comprises the mean concentration for a 24-hour sampling period as either a composite sample concentration or the
arithmetic mean of all grab samples collected during that period. (40 CFR 122.2)
Daily Maximum

the Division received EPA approval to allow a 50 ug/L TRC compliance level. A footnote. regarding this change has
been added to the effluent limitations page in the draft permit. Please note that in 2009, the entire Big Laurel
Creek Water shed has been reclassified to Outstanding Resources Waters (ORW). This ORW stream
The existing North Carolina Water Quality standard for Aluminum is 87 ug/L, a review of Aluminum values
reported on your DMR'.s since your last permit was issued reflect Aluminum a daily average value of 1,118
ug/L.. In the future if a water quality standard is required, your facility will have to address this elevated
value for compliance purposes.
This draft permit'contains the following changes from your existing permit:
• The classification of Big Laurel Creek has been changed to C = Trout ORW.
• - The site map has been updated to reflect lat & long values for your discharge point.
• Parameter codes have been added to the effluent page.
• Footnotes have been modified and added.
• Sampling frequencies have been changed for:
o Iron from Weekly to Quarterly.
o Aluminum from Weekly to Quarterly.
o Flow from Weekly to 2/Month
o TRC from Weekly to 2/Month
• Additional monitoring requirements have been added for the following. Pollutants of Concern:
o Turbidity — 2/month sampling.
o Copper — Quarterly sampling.
o Manganese - Quarterly'sampling.
o Zinc — Quarterly sampling.
o Whole Effluent. Toxicity (Monitoring only) — Quarterly sampling.

recovery of water to the reservoirs.
We can concur with your proposal but request the following action to Insure -
continued protection of your source water:
1. That any timbering above the main drainage basin to each reservoir be
accomplished by the use of aerial extraction as your correspondence
reflects..
2. That any heavy timbering be accomplished only in the mid -range between
the two reservoirs. Proper erosion control, silt screening and drainage basins
are to be used and maintained.
3. That you designate a refueling, lubrication and equipment storage area below
the confluents of each reservoir.
4. That no herbicides be used for selective thinning or undergrowth reduction.
5.- Portable toilets are required for -human use on the watershed. Proper health
screening of all .personnel working on the watershed is required.
We will await receipt of your forest management plan prior to commencement of the
project. The plan should include daily inspection by a representative of the town with
watershed inspection and activity reports maintained and readily available for review by
this agency., You should, also plan for routine quality, monitoring of at least turbidity and

bacteriological analysis. Daily logs should be kept of who is working, time in and out with
what types of activities are occurring. Care should be taken to secure the area during none
timbering periods or at the end of each work day.
Since your water treatment plant is a non -conventional type you should take great
precautions to maintain the WS I integrity of the watershed. You will need to notify the
Division of Water Quality of your intent to protect downstream waterways as well.
We will look forward to working this project with you and feel confident that your
planning will insure protection of your supply and provide safe drinking water during the
course of the project.

permit
Attachments: 02-17-2011(2).pdf
Hi Bob,
Here's what I would suggest for the DRAFT permit:
➢ Supplement to permit cover sheet (change as follows):.
1. Continue to operate ...
Delete: "sand filter"
It is NOT part of the wastewater treatment process.
Add: "tablet" dechlorinator
➢ Based on the following new WTP permitting strategy, the DRAFT permit appears
correct.
EFFLUENT CHARACTERISTICS - MONITORING REQUIREMENTS - LIMITS:
■ Flow: measurement frequency - continuous recording - see footnote # 1.
■ TSS limits: 30 mg/L mo ave. & 45 mg/L weekly ave - see footnote# 3.
■ pH limits: 6.0 — 9.0 units - see footnote # 3.
■ Total Residual Chlorine: 17-28 pg/L daily max limits -see footnotes # 2 & #
3.
■ Turbidity: see footnotes # 3. & # 4.
■ Aluminum: monitor quarterly - limit based on potential - see footnote # 10.
■ Total Iron: monitor quarterly - limit based on potential - see footnote # 10.
■ Total Copper: monitor quarterly - limit based on potential - see footnote #
10.
■ Manganese: monitor quarterly - limit based on potential - see footnote # 10.
■ Fluoride: monitor quarterly - limit based on potential - see footnotes # 5. &
# 10.
■ Total Zinc: monitor quarterly - limit based on potential - see footnotes # 6.
& # 10.
■ Ammonia Nitrogen: monitor quarterly - see footnote # 7.
■ Total Phosphorus: monitor quarterly. - see footnote # 8 .
1

■ Total Nitrogen: monitor quarterly - see footnote # 8.
■ Whole Effluent Toxicity: monitor quarterly - see footnote # 9.
Footnotes:
1. Continuous discharges > 50,000 gpd are required to perform
continuous recording flow measurements. For intermittent discharges,
instantaneous flow monitoring is required and the duration of the
discharge must be reported. The monitoring frequency for flow should be
the same as the most frequently monitored parameter listed. Instantaneous
measurement or estimates are allowed if the permitted flow is less than
50,000 gpd.
2. Limit and monitor only if the facility adds chlorine or chlorine derivatives to
water that is eventually discharged. The Division shall consider all effluent
TRC values reported below 50 ug/I 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 ug/I.
3. Monitor 2/month if discharge is < 0.6 MGD and monitor weekly if discharge is
>0.5 MGD.
4. If the receiving stream is impaired for turbidity, a daily maximum limit should
be given.
5. Fluoride should be monitored if the permittee backwashes with fluoridated
finished water.
6. Zinc should be monitored if the permittee adds zinc orthophosphate as a
corrosion inhibitor prior to backwashing.
7. Ammonia nitrogen should be monitored if the permittee uses choramines
(adds ammonia to chlorinated water) for secondary disinfection prior to
backwashing.
8. Facilities under 0.05 MGD should only monitor for nutrients if discharging into
Nutrient Sensitive Waters.
9. WET (Whole Effluent Toxicity) Testing Requirements.
10. Parameter should be monitored in conjunction with the toxicity tests.
➢ Everything else looks good.
➢ ARO recommends renewal of this permit.
Thanks,

Wanda

Town of Mars Hill Water Plant Lagoon
Solids Handling Plan
At the current time The Town of Mars Hill is utilizing a Geotube to dewater our Alum
Sludge. We have a temporary permit to place the Geotube. above the Lagoon and the
effluent from the Geotube is carried back to the Lagoon before discharge. At such time
when the Geotube is full and dry the town will haul the alum sludge to Madison County
Landfill to be incorporated with the topsoil on landfill cells.
4p6i 9. Amu�,
5/a 1 /0 6

For Large or Small' Dewatering Requirements,
Geotube® Technology Works.
Geotubea dewatering technology can be used to dewater millions of gallons of sludge from a
lagoon, or take care of smaller dewatering needs. It's versatile, inexpensive, and very efficient.
Now Geotube® Technology Works
Dewatering with Geotube° technology I
is a three -step process.
1. Filling
Sludge is pumped into the
Geotube® bag. Environmentally
safe polymers are added to the
sludge, which makes the solids
bind together and water separate.
2, Dowatering
Clear effluent water simply
drains from the Geotube°
system. Over 99% of solids
are captured, and clear filtrate
is returned to the headworks
of the plant. 40
S. Consolidation
Solids remain in the bag.
Volume reduction can be ups
to 80%. When full, the
Geotube® bag and contents can
be deposited at a landfill, or the
solids removed and land -applied.
Gootubell Technology In Action:
1. Raw sludge before treatment.
2. After treatment with polymer to
promote solid bonding.
3. After dewatering through a Geotube®
system.
i
Under proper conditions, Geotube' Muef ilibe-
units can also be used in drying beds to
increase capacity.
The Simplest Nigh Volume
Dewatering System Ever
There are no belts or gears. Geotubell bags are
available in a variety of sizes, depending on your
volume and space requirements. Our Geotube
MuniTube' bags are sized to fit into drying beds.
Geotubel systems can be stacked to maximize your
available footprint or can be fabricated to fit in mobile
roll -off containers that can be transported around your
property as necessary.

Per your request, I talked with Darhyl Boone from the Town of
Mars Hill about the stage of WTP construction. He stated that
the site had been graded for installation of the tank and the
backwash pond. They are laying the water lines and digging the
wet well now. They are also doing work on the storage tank in
preparation for pouring the slab. They should have all the
concrete work finished by December (196). The plant should be
on-line by the Spring (197).
The ARO recommends renewal of the NPDES permit as proposed.

Nolichucky River Mainstem (04-03-06 through 04-03-07)
No DO problems in the Nolichucky watershed have been documented through DEM's
ambient monitoring network nor by NPDES instream self -monitoring. data. There are a few
discharges of oxygen -consuming wastes in the -watershed. In addition, water temperatures are low
and flow is available to assimilate wastes. Thus, no field calibrated models have been done.
Permit limits for oxygen -consuming wastes will be determined in accordance with standard
procedures.
Subbasin 06 (North and South Toe River Watersheds)
I
North Toe River
There are a few domestic discharges in this basin, most discharges are from mineral
process industries. The largest municipal discharge is the Spruce Pine WWTP (0.8 MGD) which
is expected to continue to expand. Smaller municipalities include Bakersville and Newland. There
is no interaction between domestic discharges. The most significant discharges in the basin are
quartz, feldspar and mica mines which contribute to the sedimentation of the North Toe River, but
which have no oxygen -consuming wastes. The empirical model will be used to determine permit
limits for new and expanding discharges.
Tittle Crabtree Creek
A tributary to the South Toe, Little Crabtree Creek and its tributaries George Fork and
Allen Branch include 4 existing and 1 proposed discharge. An empirical model of these discharges
shows no interaction between discharges and water quality at background conditions prior to
confluence with the South Toe River.
Yancey County and the Town of Burnsville have proposed a new regional facility which
will serve this area and eliminate the individual discharges. The proposed 300,000-gallon per day
municipal wastewater plant may discharge to the South Toe River approximately one mile below
the ORW classification line. The plant will include textile waste and will tie in the four small
facilities nearby. A new feldspar mine has also been proposed for this reach but is not expected to
have any oxygen -consuming waste components.
Lower North Toe River
The North Toe River below the South Toe River has no direct discharges. The only
discharge -is Tipton Hill School which discharges to Racoon Creek. Part of the North Toe River
may be upgraded to Class B waters since the waters are used for whitewater rafting.
Nolichucky River
The Nolichucky River is formed by the confluence of the Cane and North Toe Rivers.
There are no discharges to the Nolichucky River or its tributaries. The river may be reclassified to
B waters due to recreational usage. A reclassification study is planned for,the summer of 1995.

Dear Mr. Boone:
The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject
facility. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1
and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection
Agency dated October 15, 2007, or as subsequently amended.
The Division understands that you have made no significant changes to your facility since the last permit
renewal. We have made the following updates .to your previous permit:
1. Turbidity monitoring is twice per month (2/month) with a monthly average limit of 50 NTU and a
daily maximum limit of 50 NTU.
2. Total lion and Total Manganese monitoring has been removed.
3. Total Copper monitoring has been removed because it did not show reasonable potential to
exceed applicable water quality standards/criteria and the maximum predicted concentration was
<50% of the allowable concentration.
4. Effluent and upstream quarterly monitoring for Total Hardness (see below for information) has
been added.
5. Electronic reporting of discharge monitoring reports (eDMR) in Section A. (4.) has been added.
The NC-2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently approved
the WQS revisions on April 6, 2,016 with some exceptions. The NC Division of Water Resources NPDES
Permitting. Unit is required to implement the new dissolved metal standards in all permits public noticed after
April 6, 2016.
The new standards for most metals include acute standards. Furthermore, the freshwater standards for several
metals are expressed as the dissolved form of the metals, and seven metals have hardness -dependent
equations. As a result, the NPDES Permitting Unit will need site -specific effluent hardness data and instream
hardness data, upstream of the discharge, for each facility monitoring:these.metals;incjrderfocalculatepermit
limitations. Effluent hardness and instream hardness sampling, upstream of the discharge, has been added to
this permit at a monitoring frequency of quarterly. See Section A. (1.) Effluent Limitations and Monitoring
Requirements.

1. Starting December 21, 2016, begin submitting Discharge Monitoring Reports electronically using NC DWR's
eDMR application system. See Condition A. (3.).
2. For instantaneous flow monitoring, the duration of the discharge must be reported in addition to the
total flow.
3. Turbidity — Effluent turbidity shall not cause receiving -stream turbidity to exceed 50 NTU. If background
turbidity naturally exceeds 50 NTU, the effluent shall not cause background turbidity to increase. Any
discharge exceeding this permit limit will require sufficient instream sampling (upstream and/or downstream)
to verify compliance (effluent vs. background)." [NCAC 02B. 0211(21)]
4. The Division shall consider all effluent TRC values reported below 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.
5. Effluent hardness sampling should be performed in conjunction with sampling for hardness dependent metals
(zinc).
6. The Permittee shall sample instream hardness, upstream of the facility's discharge. The sample shall be
representative of the hardness in the receiving stream. If the Permittee is a member of the Monitoring Coalition
Program, sampling for instream hardness may be waived as long as the Monitoring Coalition agrees to sample
Page 3 of 8

NPDES Permit NC0083712
hardness at the nearest upstream location, at a minimum frequency of quarterly, and the Permittee has obtained
approval from DWR NPDES Permitting Unit that the upstream station being monitored by the Coalition is
representative of the receiving stream for this discharge. The Permittee is responsible for submitting instream
hardness test results with its permit renewal application package. If Coalition membership is cancelled or the
Coalition terminates instream hardness sampling at the approved station; the Permittee will immediately notify
the Division and resume sampling for instream hardness, upstream of its discharge.
7. Chronic WET testing (Ceriodaphnia dubia) 7-day pass/fail test at 3_3% in January, April, July and October.
See Condition A. (2.).
Conditions:
• Samples shall be taken at `the outfall but prior to mixing with the receiving waters.
• There shall be no discharge of floating solids or visible foam in other than trace amounts.
Page 4 of 8

NPDES Permit NCO083712
A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING ONLY (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
The permittee shall conduct quart erlx chronic toxicity tests using test procedures outlined in the "North
Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent
versions.
The effluent concentration defined as treatment two in the procedure document is 3_3%. The testing shall be
performed as a Ceriodaphnia dubia 7-day pass/fail test. The tests will be performed during the months of
January, April, July and October. These months signify the first month of each three month toxicity testing
quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative
effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment
processes.
All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge
Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B.
Additionally, DWR Form AT-1 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh, North Carolina 27699-1621
Completed Aquatic Toxicity Test Forms shall be filed with the Water.Sciences Section no later than 30 days
after the end of the reporting period -for which the. report is made:
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed
in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent
toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required,
the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating
the facility name, permit number, pipe number, county, and the month/year of the report with the notation of
"No Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the
address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
Should any test data from this monitoring requirement or tests performed by the North Carolina Division of
Water Resources 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.

Records Retention
Monitoring Reports
1. Reporting Requirements [Supersedes Section D. (2.) and Section E. (5.) fall
The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic
Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month and
submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. Until such time that the state's
eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation
(CROMERR), permittees will be required to submit all discharge monitoring data to the state
electronically using eDMR and will be required to complete the eDMR submission by printing,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements may
be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3)
or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the
mailing address above. See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month following
the issuance of the permit or in the case of a new facility, on the last day of the -month following the
commencement of discharge.
Starting on December 21, 2020, the permittee must electronically report the following compliance
monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Page 6 of 8

NPDES Permit NCO083712
• Clean Water Act (CWA) Section 316(b) Annual Reports.
The permittee may seek an electronic reporting waiver from the Division (see "How to Request a
Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time
of each electronic submission. The permittee should use the EPA's website resources to identify
the initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated
entity for receiving electronic NPDES data [see 40 CFR 127.2(b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: http://www2.epa. ov/compliance/final-national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule.
Electronic submissions must start by the dates listed. in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring
data and reports shall be submitted electronically to the Division unless the permittee re -applies for
and is granted a new temporary electronic reporting waiver by the Division. Approved electronic
reporting waivers are not transferrable. Only permittees with an approved reporting waiver request
may submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:

PART IV
SPECIAL CONDITIONS FOR MUNICIPAL FACILITIES
Section A. Definitions
In addition to the definitions in Part II of this permit, the following definitions apply to municipal facilities:
Indirect Discharge or Industrial User
Any non -domestic source that discharges wastewater containing pollutants into a POTW regulated under section
307(b), (c) or (d) of the CWA. [40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(I1)]
Interference
Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which
causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the
Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in
compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H
.0903 (b)(14)]
Pass Through
A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with
discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of
the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge
permit. [15A NCAC 02H .0903(b)(23)]
Publicly Owned Treatment Works (POTW)
A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization.
This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal
sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T
.0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government
organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges
to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW
treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of
POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)]
"Significant Industrial User" or "SIU"
An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H
.0903(b)(33)]:
1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary,
noncontact cooling and boiler blowdown wastewaters); or
2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted
flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS
and ammonia; or
3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or
4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely
affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent
limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options;
5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraphs I or 2 of this definition above has no reasonable potential for adversely affecting the
POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and
conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a
Significant Industrial User (SAI); or .
6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting
the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a
non -significant categorical Industrial User.
Section B. Publicly Owned Treatment Works (POTWs)
Version 1110912011.1

NPDES Permit Standard Conditions
Page 15 of 18
All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]:
Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of
transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants;
and
Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as
influent to that POTW at the time of issuance of the permit.
For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent
introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or
quality of effluent to be discharged from the POTW.
Section C. Municipal Control of Pollutants from Industrial Users.
1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users
discharging to the POTW may be present in the Permittee's discharge. At such time as sufficient information
becomes available to establish limitations for such pollutants, this permit may be revised to specify effluent
limitations for any or all of such other pollutants in accordance with best practicable technology or water quality
standards.
2. Prohibited Discharges
a. The Permittee shall develop and enforce their Pretreatment Program to implement the prohibition against the
introduction of pollutants or discharges into the waste treatment system or waste collection system which
cause or contribute to Pass Through or Interference as defined in 15A NCAC 02H .0900 and 40 CFR 403. [40
CFR 403.5(a)(1)]

wastestreams with a closed cup flashpoint of less than 140 degrees Fahrenheit or 60 degrees Centigrade
using the test methods specified in 40 CFR 261.21;
(2) Pollutants which cause corrosive structural damage to the POTW, but in no case discharges with pH lower
than 5.0, unless the works is specifically designed to accommodate such discharges;
(3) Solid or viscous pollutants in amounts which cause obstruction to the flow in the POTW resulting in
Interference;
(4) Any pollutant, including oxygen demanding pollutants (BOD, etc.) released in a Discharge at a flow rate
and/or pollutant concentration which will cause. Interference with the POTW;
(5) Heat in amounts which will inhibit biological activity in the POTW resulting in Interference, but in no
case heat in such quantities that the temperature at the POTW Treatment Plant exceeds 40°C (104°F)
unless the Division, upon request of the POTW, approves alternate temperature limits;
(6) Petroleum oil, non -biodegradable cutting oil, or products of mineral oil origin in amounts that will cause
Interference or Pass Through;
(7) Pollutants which result in the presence of toxic gases, vapors, or fumes within the POTW in a quantity that
may cause acute worker health and safety problems; or
(8) Any trucked or hauled pollutants, except at discharge points designated by the POTW.
c. The Permittee shall investigate the source of all discharges into the POTW, including slug loads and other
unusual discharges, which have the potential to adversely impact the Permittee's Pretreatment Program and/or
the operation of the POTW.
The Permittee shall report such discharges into the POTW to the Director or the appropriate Regional Office.
Any information shall be provided orally within 24 hours from the time the Permittee became aware of the
circumstances. A written submission shall also be provided within 5 days of the time the Permittee becomes
aware of the circumstances. The written submission shall contain a description of the discharge; the
investigation into possible sources; the period of the discharge, including exact dates and times; if the

Mars Hill WTP
Madison County
Dear Mr. Sams:
On August 1, 2014, the Division of Water Resources (DWR) issued a General Permit NPDES permit
(NCG590000) for wastewaters from Greensand and Conventional type water treatment plants. This
permit was developed to expedite the issuance and reissuance of these types of permits.
The Town of Mars Hill's existing Individual NPDES permit for its Mars Hill Water Treatment Plant.
(WTP) is up for renewal and qualifies for coverage>underalusm Gen eTal Periniti;The; anog44ermit fee
for'the general permit is $100 verses $860 for an Individual permit and monitoring is less frequent than
that listed in your current permit.
Similar to Individual NPDES permits; general permits expire every five years but can be renewed by
completing a short and simple general permit renewal form. The General Permit is reissued every five
years and is sent to all the Permittees covered under it, all at the same time.
To switch to the General permit, the Town will need to make a written request to DWR. Please note, the
issuance of the General Permit would require the recession of your individual permit. The Division
suggests that you review the attached file containing the General Permit NCG590000 and decide whether
you would like the Division to renew the individual permit or proceed with issuance of the General permit
via a Certificate of Coverage for the WTP. Note that the Town of Mars Hill operates a conventional water
treatment system that discharges to freshwater, so the facility would be subject to the limitations listed on
page 5 (B. (3.) Conventional WTP Effluent Limitations and Monitoring Requirements —
Discharging to Freshwater) in the attached,General permit.
To request that the Division proceed with issuing the General Permit instead of renewing the existing
Individual permit, the City should respond with something like the following: 5
The Town•of Mars Hill has reviewed the Division of Water Resources General Permit
NC65900000 for greensand and conventional type water treatment plants and
requests that the discharge from the Mars Hill WTP be covered under this new
general permit. The Town understands that the Division will rescind the individual-
NPDESpermit for the Town of Mars Hill WTP — NCO083712 when the Certificate of
Coverage for the General Permit NCG590000 is issued to the Town for the WTP.

Comment: Inspector has asked the facility to sample Aluminum (AI) upstream and
downstream when sampling effluent for Al. This is not a requirement, jusfa request to
see if the stream is assimilating the Al. They were told they could do the upstream and
downstream at their lab since it is not to be used for compliance. The quarterly Al
effluent sampling is still to be performed by a certified lab. But if they could sample the
effuent, upstream and downstream at their convenience for informational purposes it
would be appreciated.

Comment: How the solids are handled was discussed. A Geotube is used to gather
solids. Aproximately every 4-5 years the facility has to remove solids from the lagoon.
They are planning on removing solids the summer of 2013. They expect to hire a
company to assist them. The removal process was described as a' flexible tube placed
in the lagoon. and moved around where or when needed which will bring the solids
slurry to the Geotube. Chemicals may be added to assist with Geotube settling. The
chemical to be used is unknown, it may be dependent on company assisting. The
inspector informed staff that the chemical used has to be a DWQ approved chemical.
And it is also crucial that the chemical be used correctly, otherwise it could -be illegally
discharged to the stream.

There appeared to be some short circuiting in the lagoon but the effluent did not confirm
this. The pipe delivering backwash water to the lagoon is located close to the outfall
from the lagoon. The pipe is angled to direct water around the lagoon but there was
some suspended material near the outfall. However, during the inspection the effluent
into the stream did not indicate any visible solids.

Chemical wastewater treatment facility. Filter backwash from the water plant is discharged into
a sludge holding lagoon (approximately 100 ft x 50 ft) for settling. The effluent is
dechlorinated by use of a tablet dechlorinator. The accmulated sludge was pumped to a Geotube
and dewatered last fall. Once dry, the solids will either be taken to the landfill or land
applied.
PERMIT / INSPECTION / LOG:,
A review of the files indicates that the last. compliance evaluation inspection was
conducted on 3-7-2007 by Janet Cantwell.
The permit expires on 9-30-2010. A renewal application has been submitted by the permittee.
EFFLUENT DATA:
Temperature = 8.8 degrees Celsius
pH = 7.3 units
Chlorine = <17 ug/I
OPERATIONS AND MAINTENANCE / EFFLUENT / SUMMARY:
Mr. Robert Sams, Director of Public Works, assisted in the inspection. He and Mr. Steve Rector
appear to be operating and maintaining the facility very well.

TYPE OF INSPECTION: Field Maintenance
AUDITOR(S):
LOCAL PERSON(S) CONTACTED
INTRODUCTION:
Gary Francies, Jason Smith
Robert Sams, Steve Rector
This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
GENERAL COMMENTS:
The staff is congratulated for doing a good job of maintaining the Field Testing Certification program.
The facility has all the equipment necessary to perform the analyses. Most data appeared accurate.
Documentation needs to be improved. Some further quality control procedures need to be
implemented.
Comment: Findings B and Fare new policies that have been implemented by our program since the last
inspection.
FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Documentation:
Comment: Worksheets provided by the NC Wastewater/Groundwater Laboratory Certification (NC
WW/GW LC) program during the previous inspection are currently being used. A newer version of this
worksheet should be downloaded and modified to the needs of the facility.
A. Finning: Proper units of measurement are not included on the benchsheet for pH and Total
Residual Chlorine.
Requirement: Data pertinent to each analysis must be maintained for five years. Certified data
must consist of date collected, time collected, sample site, sample collector, and sample
analysis time. The field bench sheets must provide a space for the signature of the analyst, and
proper units of measure for all analyses. Ref: 15A NCAC 2H .0805 (g) (1).
B. Finding: The time the Dissolved Oxygen meter is calibrated needs to be documented. This is
considered pertinent information.

Page 2
#5053 Town of Mars Hill WWTP
Requirement: The following criteria must be documented whenever sample analysis is
performed: date and time collected, date and time of analysis, sample site, collector's/analyst's
name, meter calibration time(s), all data must be labeled with the proper units of measure and
reported in units of mg/L, the temperature correction (even if it is zero) must be posted on the
meter as well as in hard copy format (to be retained for 5 years). Ref: NC WW/GW LC
Technical Assistance for Field Analysis of Dissolved Oxygen Rev. 09/07.
-Conductivity Standard Mefhods, 18t" Edition, 2510 B
pH — Standard Methods, 18th Edition, 4500-H+ B
C. Finding: The conductivity standard and pH buffers are expired.
Requirement: Some standardized solutions alter slowly because of chemical or biological
changes. The practical life, required frequency of standardization, or storage precautions are
indicated for such standards. Ref: Standard Methods, 18t" Edition 1070 C. 3. c.
Comment: Chemicals must be used within the expiration period stated by the manufacturer.
Chemicals exceeding the expiration date can no longer be considered reliable.
Conductivity— Standard Methods, 18t" Edition, 251Q B
D. Finding: The meter is not calibrated each day of use as required. This calibration must also be
documented.
Requirement: With probe in standard KCL solution, adjust meter to read value of standard.
This procedure automatically adjusts cell internal to the meter. Ref: Standard Methods, 18th
Edition, 2510 B. 4. a. .
Requirement: The following criteria must -be documented whenever sample analysis is
performed: date and time of sample collection, date and time of sample analysis,
collector/analyst's name, sample site/sample identification, value of standard used for
calibration instrument calibration time concentration and obtained value of the check standard,
reported values for all samples in pmhos/cm at 251 C or corrected to 250 C, The temperature
correction (even if it is zero) must be posted on the meter as well as in hard copy format (to be
retained for 5 years). Ref: NC WW/GW LC Technical Assistance for Field Analysis of
Conductivity Samples Rev. 09/07.
Recommendation: It is recommended that the meter be checked with a standard in the
concentration range of the samples analyzed, in addition to the daily calibration.
pH --Standard Methods,18t" Edition, 4500.H+ B
E. Finding: Following calibration, a buffer is not analyzed to check the calibration of the meter.
Requirement: In addition to the calibration standards, a buffer calibration check must be
performed: Ref: NC WW/GW LC Technical Assistance for Field Analysis of pH Rev. 09/07.
Recommendation: The meter is currently calibrated with pH 4, 7, and 10 buffers. It is
recommended that the meter be calibrated with the pH 4 and 10 buffers. The 7 buffer can then
be used as the check buffer for the calibration.

Page 3
#5053 Town of Mars Hill WWTP
Recommendation: It is recommended that the pH 7 buffer be checked and documented after
all analyses are complete when the meter is used at both the Wastewater Treatment Plant and
the Water Treatment Plant on the same day.
Temperature — Standard Methods, 181h Edition, 2550 B
F. Finding: The temperature correction is not posted on the.,meter.
Requirement: All thermometers, or temperature sensing devices on field meters, must meet
NIST specifications for accuracy or must be calibrated against an NIST certified or NIST traceable
thermometer annually (every twelve months) and proper corrections made and documented. The
thermometer reading must be less than 10C from the NIST certified reading to be acceptable.
Also document any correction that applies on both the instrument and on a separate sheet to be
filed. A correction factor must be posted on the meter even if that correction factor is 0 degrees.
The temperature sensor must be calibrated annually even if it is not being used to report
temperature. Ref: NC WW/GW LC Policy February 2006.
Total Residual Chlorine —Standard Methods, 18'h Edition, 4500-CI G
G. Finding: The gel standard used to verify the calibration curve daily has not been assigned a true
value.
Requirement: Purchased "Gel -type" or sealed liquid ampoule standards may be used for daily
calibration verification only. These standards must be verified initially and every 12 months
thereafter, with the standard curve. The assigned values will be used for the next twelve
months, or until a new curve verification is performed. The gel standard verification must be
performed for each instrument on which they are to be used. if multiple instruments and/or
standard sets are used, each must have assigned values specific for the instrument and
standard set. Ref: NC WW/GW LC Technical Assistance for Field Analysis of Total Residual
Chlorine Rev. 09/07.
Comment: It is only necessary to verify the gel or sealed liquid standard which falls within the
concentration range of the curve used to measure sample concentrations. For example, if you
are measuring samples against a low range curve, a 200 pg/L standard would be verified, and
not the 800 pg/L standard since the 800 pg/L standard would be measured using a high range
curve.
Recommendation: It is recommended that the gel standard be checked and documented after
all analyses are complete when the meter is used at both the Wastewater Treatment Plant and
the Water Treatment Plant on the same day.
H. Finding: Performance Evaluation samples are not analyzed using the correct program on the
meter. NPDES samples are analyzed on the Ultra Low Level Total Residual Chlorine (TRC)
program (Ng/L); however Performance Evaluation samples are analyzed on the regular level TRC
program (mg/Q.
Requirement: "The DMR-QA study is designed to evaluate the entire process you use to
routinely report results in your Discharge Monitoring Reports." This process includes analyzing
the Performance Evaluation samples the same way you analyze routine samples (using the same
standard curve used to analyze samples). Ref: EPA DMR-QA Study 28 Letter, March 10, 2008.

Page 4
#5053 Town of Mars Hill WWTP
Recommendation: Some Performance Evaluation sample vendors now provide Ultra Low
Level TRC samples. It is recommended that this Performance Evaluation sample be analyzed
in the future to avoid introducing errors to the result due to dilution.
Dissolved Oxyaen — Standard Methods,18`h Edition; 4500-0 G
Recommendation: The Dissolved•.Oxygeri meter is calibrated automatically based upon eleva#ion.and
percent saturation. It is recommended that this information be documented at the time of calibration.
Since the elevation is always the same, this can be typed in the worksheet rather than recorded each
day, however the percent saturation should be recorded each day.
IV. PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing field testing records and contract lab reports to Discharge
Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Quality. Data were
reviewed for Town of Mars Hill WWTP (NPDES permit # NC0057151) and Town of Mars Hill WTP
(NPDES permit # NC0083712) for September and October, 2007. No transcription errors were
detected. The facility appears to be doing a good job of accurately transcribing data.
I. Finding: Values less than the established minimum reporting level are reported.
Requirement: One of the standards must have a concentration equal to or below the lower
reporting concentration for TRC. Example: If the laboratory chooses to have a lower reporting limit
of 17 pg/L for TRC, you must analyze at least 17 pg/L or lower standard and report lower
concentrations as < 17 pg/L, or < the concentration of the chosen standard. Ref: NC WW/GW
LC Technical Assistance for Field Analysis of Total Residual Chlorine (revision date 9/07).
Requirement: Values of results which are less than a detectable limit should be reported in the
daily cells using the 'less than" symbol (<) and the detectable limit used during the testing (or
the value with appropriate unit conversion). Ref: Division of Water Quality document; Directions
for Completing Monthly Discharge Monitoring Reports.
Comment: The contract lab supplies the reporting limit when the curve is verified each year.
V. CONCLUSIONS:
Correcting the above cited findings and implementing the recommendations will help this lab to
produce quality data and meet certification requirements. The inspector would like to thank the staff for
their assistance in the inspection and data review process. Please respond to all findings.

Dear Mr. Francis:
In response to those issues addressed during the inspection conducted by you and
Mr. Smith.
A. Proper units of measure for chlorine and pH will be included in current and future
bench sheets.
B. The DO calibration time will be added to our bench sheets and we will document
actual number value instead of just noting auto calibration.
C. I have ordered new pH buffers and conductivity standard.
D. The conductivity meter is now being calibrated daily and it is being recorded.
E. The pH 4 and 10 buffers are now being used for calibration and we are using pH 7
for a check.
F. Temperature correction has been posted on the meter used to measure temperature
and the corrections have noted on bench sheets.
G. We have assigned a true value by doing a series of checks on the gel standards
and will be using the 200 ug/l as a standard.
H. The next PE samples will be analyzed using the correct program. It is possible
that I will go to the regular level (TRC) program if I can get the level of accuracy
needed.
I. All values of less than 17 ug/L will be reported as <17 ug/L instead of exact
value.
I hope this has addressed all the noted issues in you letter.
