Subject: Issuance of NPDES Permit NCO044423
Appalachian State Univ. WTP; PC -1
800 Rainbow Trail Road
Watauga County
The Division of Water Resources (DWR of the Division) hereby issues the attached discharge permit
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 (EPA) dated
October 15, 2007 (or as subsequently amended).
Please note that since last renewal, the receiving waterbody has been re-classified "High Quality
Waters" (HQW). Because the subject water treatment plant (WTP) discharges to WS -II; Trout; HQW;
CA, this facility is ineligible for WTP General Permit NCG590000.
Based on Appalachian State University's (ASU's) application to renew and our site visit on July 7,
2016, the Division understands that since last renewal, you have made no significant changes to your
low-pressure membrane treatment processes. We have made changes to your permit by updating the
permit format and site map. In addition, we offer the following discussion of new requirements for
renewal.
Changes for Renewal:
In keeping with revised permitting strategies for potable WTPs, the Division has
discontinued monitoring for Chloride and Total Iron. We have added Turbidity limits (10
NTU) and a limit for Dissolved Oxygen (6.0 mg/L) consistent with requirements for Trout
waters. We have also discontinued Chronic Whole Effluent Toxicity (WET) testing
[TGP3B] and replaced it with Acute Quarterly WET testing [TGE6C] in accord with
current WTP strategies [see section A. (L)].
Please note that if WET -test results indicate "Fail" you must resample and retest monthly until
tests indicate "Pass," as noted in section A. (2.):
"Should any single quarterly monitoring indicate a failure to
meet specified limits, then monthly monitoring shall begin
immediately until such time that a single test is passed. Upon
passing, this monthly test requirement will revert to quarterly
in the months specified above. "

Issuance - February 14, 2017
2. On April 6, 2016 the Environment Protection Agency (EPA) adopted new criteria for
metals considering their "dissolved fraction," as approved in the Triennial Review
(November 13, 2014) by the NC Environmental Management Committee
(EMC). Therefore, our review of metals and limits calculations requires additional
monitoring for Hardness (Ca + Mg or CaCO3). We have therefore added Quarterly
monitoring of both effluent and upstream Hardness (parameter code 00900).
3. In accordance with the new metals criteria, this renewal includes permit limits for Total Copper
and Total Zinc based on their Reasonable Potential Analyses (RPAs) of ASU's self-monitoring
database. To date, these data show reasonable potential for each metal to exceed its respective
water -quality standard, and therefore a permit limit is required.
4. Although ASU's past NPDES permits have granted effluent dilution by the receiving stream
(Norris Branch), this dilution is not valid for a lake discharge (Norris Branch Reservoir). It
follows that effluent limits for metals will receive no credit for dilution until a dilution factor or
a valid discharge alternative may be established for the lake. In the interim, permit limits appear
in the permit, each equal to its respective surface water -quality standard or allowable
concentration, not to exceed [see permit A. (1.)].
5. Anticipating your need to comply with metals limits, the Division has included a compliance
period wherein ASU may evaluate and report on discharge alternatives [see Special Condition
A. (3.)].
Implementing Electronic Discharge Monitoring Reports (eDMRs). Please be advised that the Division
has implemented an electronic Discharge Monitoring Report (eDMR) program, in accord with recently
promulgated requirements by the Environmental Protection Agency (EPA). We include the details to
implement the eDMR program in this permit [see Section A. (4.)].
Federal regulations require electronic submittal of all DMRs and specify that, if North Carolina does
not establish a program to receive such submittals, Permittees must then submit eDMRs directly to
EPA. For more information on eDMRs, registering for eDMR submittal, and obtaining an eDMR user
account, please visit DWR's webpage:

For information on EPA's proposed NPDES Electronic Reporting Rule, please visit EPA's website:
h a/www2.epa.govlcompliance/proposed-npdes-electronic-re ottin -rule
If any parts, measurement frequencies or sampling requirements contained in this permit are
unacceptable, you have the right to an adjudicatory hearing upon written request submitted within thirty
(30) days following receipt of this letter. This request must take the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes, and filed with the Office of
Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina 27699-6714). Unless such
demand is made, this decision shall be final and binding.

Footnotes:
1. Beginning no later than December 21, 2016, the Permittee shall report discharge monitoring data
electronically using the NCDWR's Electronic Discharge Monitoring Report (eDMR) internet application. [See
Section A. (4.) for eDMR submittal requirements]. Monthly DMRs shall indicated "no flow," if appropriate.
2. U = Upstream 200 ft from the outfall [lake]; E = Effluent; the duration of each discharge shall be noted in log books.
3. Total Residual Chlorine (TRC) - The Division shall consider compliant all effluent TRC values reported below 50
µg/L. However, the Permittee shall continue to record and submit all values reported by North Carolina -certified
test methods (including field certified), even if these values fall below 50 µg/L.
4. Turbidity — Effluent turbidity shall not cause receiving -stream turbidity to exceed 10 ntu. If background turbidity
naturally exceeds 10 ntu, the effluent shall not cause background to increase. Exceeding this permit limit will
require sufficient instream sampling (upstream and/or downstream) to verify compliance (effluent vs. background)
[NCAC 02B. 0211(21)].
5. Compliance to this limit becomes effective on January 1, 2021. Modification of this limit requires further
evaluation of the discharge [see Special Condition A. (3.)].
6. Whole Effluent Toxicity (WET) -testing; Acute 24-hour pass/fail using fathead minnow (Pimephales promelas) at
effluent concentration of 90%; during the months of January, April, July, and October; refer to Section A. (2.).
Page 3 of 7

Permit NCO044423
Conditions:
The discharge shall contain no floating solids or foam visible in other than trace amounts.
All samples shall accurately represent the physical and chemical character of the effluent.
A. (2.) ACUTE TOXICITY 24-HOUR PASS/FAIL - MONITOR ONLY
[15A NCAC 02B .0200 et seq.]
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled "Pass/Fail Methodology for Determining Acute Toxicity in A Single
Effluent Concentration" (Revised December 2010 or subsequent versions). The monitoring shall be performed
as a Fathead Minnow (Pimephales promelas) 24-hour static test. The effluent concentration at which there may
be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). The
tests will be performed during the months of .fanuary, 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.
Should any single quarterly monitoring indicate a failure to meet specified limits, then monthly
monitoring shall begin immediately until such time that a single test is passed. Upon passing, this
monthly test requirement will revert to quarterly in the months specified above.
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 TGE6C.
Additionally, DWR Form AT -2 (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 until such time that a single test is passed. Upon passing, this monthly test
requirement will revert to quarterly in the months specified above. Assessment of toxicity compliance is based
on the toxicity testing quarter, which is the three-month time interval that begins on the first day of the month in
which toxicity testing is required by this permit and continues until the final day of the third month.
Should any test data from either these monitoring requirements 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.

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
• 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. 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

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

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 hout 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
Version 11/09/2011.1

NPDES Permit Standard Conditions
Page 2 of 18
(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 only be
used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply:
➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters
➢ Influent samples shall not be collected more than once per hour.
➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab
samples at intervals of no greater than 20 minutes apart during any 24-hour period.
➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent
grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling
period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
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. For pollutants expressed in other units of measurement, the
"daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also
"Composite Sample," above.)
Daily Maximum
The highest "daily discharge" during the calendar month.
Daily SamDing
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations
prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that
requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWR or "the Division"
The Division of Water Resources, Department of Environment and Natural Resources.
Effluent
Wastewater discharged following all treatment processes from a water pollution control facility or other point source
whether treated or untreated.
EMC
The North Carolina Environmental Management Commission
EPA
The United States Environmental Protection Agency
Facility Closure
Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this
permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1.
Grab Sample
Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Version 11/09/2011.1

NPDES Permit Standard Conditions

Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA.
Instantaneous flow measurement
The flow measured during the minimum time required for the flow measuring device or method to produce a result in
that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab
samples required for the same sampling period so that together the samples and flow are representative of the discharge
during that sampling period.

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)(11)]
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 1 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 (SIU); 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 defmition 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 11/09/2011.1

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)]:

and
2. 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.
3. 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

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.
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 Perinittee 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
