Subject: Issuance of NPDES Permit NCO055221
Marion Water Treatment Plant (WTP)
801 Old Greenlee Road, Marion 28752
McDowell County
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.
We have made the following updates to your previous permit:
• removed Total Iron monitoring
• assigned Whole Effluent Toxicity (WET) testing with testing of acute Ceriodaphnia duhia
performed as 48 hour pass/fail test at 90% effluent concentration, during January, April, July
and October [See A. (2.)]
• added continuous flow monitoring.
In accordance with the NPDES Permitting Strategy for WTP's, facilities discharging greater than 50,000
gpd are required to install a continuous recorder to monitor wastewater discharge flows. As a result,
continuous flow monitoring has been added to your permit. The Division has provided a compliance
period of 18 months from the effective date of this permit to install a continuous flow meter. Until then,
instantaneous measurements can be taken provided that you record the duration- of discharge in log
books, and you report a total daily discharge on the DMR. As the 18-month compliance deadline
approaches, the City may want to consider applying for coverage under general permit NCG59000 at
which time alternatives for flow monitoring may be reevaluated.
Alternative to Continuous Recording. The continuous flow meter is not required provided that you
demonstrate instantaneous flow discharges averaging less than 50,000 gpd. To achieve this you might
discharge less water more often (at a rate not to exceed this maximum). In addition, the general permit is
available if you pass at least two (2) acute quarterly Whole Effluent Toxicity (WET) tests using
Ceriodaphnia dubia (method TGA3B- 48 hour pass/fail at 90% effluent concentration). Should you
decide to pursue NCG59, your compliance and fee obligations would significantly improve.
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
specify that, if a state does not establish a system to receive such submittals, then permittees must submit

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 after receiving this letter. Your request must take the form of a written petition conforming to
Chapter 150B of North Carolina General Statutes, and you must file it with the Office of Administrative
Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699-6714. Unless such a demand is
made, this permit shall remain final and binding.
Please note that this permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the legal
requirements to obtain other permits which may be required by the Division of Water Resources or any
other Federal, State, or Local governmental permits that may be required.

NPDES Permit NCO055221
A. (2.) ACUTE TOXICITY PASS/FAIL MONITORING FOR
WATER TREATMENT PLANTS (QUARTERLY)
The permittee shall conduct acute toxicity tests on a quarterlX basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology For Deterinining Acute Toxicity In A Single Effluent
Concentration" (Revised December 2010 or subsequent versions). The monitoring shall be performed as a
Ceriodaphnia dubia 48 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). Effluent samples for self -
monitoring purposes must be obtained during representative effluent discharge below all waste treatment. 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.
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 TGA3B.
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. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above.
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.
Should it be determined by the North Carolina Division of Water Resources that the facility's discharge
frequency and duration enable chronic sampling according to either the North Carolina Ceriodaphnia Chronic
Whole Effluent Toxicity Procedure or to Section 8.3, in Methods EPA-821-R-02-013, the permit may be re-
opened and modified to include chronic toxicity tests.
NOTE: Failure to achieve test conditions as specified in the cited document, such -as minimum control organism
survival 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.

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.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be valid
for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re -applies for and is granted a new temporary
waiver by the Division.

Mr. Carver,
Thanks for contacting me about your draft permit.
The "the two million gallon storage tanks" will be removed from the facility description for the final permit. It is
understood that these units are part of the potable water distribution system and not part of the water or wastewater
treatment system; therefore, not applicable to the NPDES permit.
Flow average is based on the days that discharge occurs. In other words, the zero discharge days are not included in the
average. For example if you discharge two days in a month with 0.600 and 0.100 MGD flows. Then the average is taken
by dividing by the number of days discharge occurs (2 days) resulting in an average of 0.350 MGD for that month. For
permitting purposes we use the maximum monthly average flow for the most recent 3 years. According to our strategy
(see attached strategy page 6, Table 3.1: Monitoring requirements for Conventional WTP) facilities with flows >_50,000
gpd are required to perform continuous (frequency), recording (sample type) flow measurements. Your facility had a
maximum monthly average of 0.373 MGD (see attached spreadsheet). The final permit will require a continuous
recording flow meter to be installed within 18 months of the effective date of the permit.
Ammonia monitoring is not required for this draft permit because ammonia nitrogen/chloramines are not in
use. However, Total Phosphorous and Total Nitrogen are required as part of our strategy (see page, Table 3.1) because
this facility has a maximum monthly average >0.05 MGD.
If you would like to be considered for the general permit in the future, I have attached a copy of general permit
NCG59000 and the Technical Bulletin for your information.
If you have any questions, please contact me.
Sincerely,
Derek

Subject: Comments requesting modification
of 'Draft NPDES Permit NC0055221'
Marion Water Treatment Plant,
McDowell County
Dear Mr. Denard,
The City of Marion Water Treatment Plant is in receipt of 'Draft' NPDES permit NCO055221 dated
December 3, 2014 and are requesting modification of same. The `Draft' NPDES permit has several
corrections which should be made, and are as follows:
On page 2 of 6 listed are two (2) two million gallon storage tanks "located" at 801 Old Greenlee
Road. This is "INCORRECT". These 7 tanks -are located on 'Reservoir Hill' within the Marion
City limits, and should not be included with this permit.
Item number 1 on page 2 of 6 of same draft has Marion WTP with a maximum `monthly
average' discharge of 0.373 MGD. This is calculated WRONG! This would perhaps -be the
monthly maximum Day. The monthly average would have to be calculated on the number of
days within that month,(i.e. 0.373 MGD divided by 30 days would equal 0.0124 MGD)? We are
attaching the "original A to U to construct the Marion WTP-WWTP, issued Nov. 24, 1986. It
states the construction of a 50,000 GPD wastewater treatment system. This is what.was
constructed, and what we continue to operate to this day. This system consists of "BATCH"
discharges and is not continuous. As such, it cannot implement footnote 2 regarding
Continuous monitoring and recording of flow. Marion WTP uses level drop of lagoon (14' deep,
with capacity of 850,000 gal. = 60,714 gal./ft), a typical batch discharge event would allow for a
4' drop within a day, and 240,000 gpd. Marion WTP would then typically not have another
discharge for 14 days to 1 month, sometimes longer.
- Monitoring of Ammonia and Total Phosphorus are not needed. Marion WTP does not utilize
phosphate based corrosion inhibitors, we use pH increase with soda ash. Marion WTP
disinfects with Chlorine, and not Chloramines, so, we do not use Ammonia at the facility.

found on the back of form MR-1 or MR- 1.1. A complete list of parameter codes can be
found on the NPDES website.
6. Units of Measurement - All data values must be accompanied by corresponding
units of measurement, noted at the top of the data column for the particular parameter. If
your permit contains a numeric limit for any parameter, then the reporting units must be
the same units of measurement of that limit. If your reporting units are other than those
on the pre-printed form, the printed units should be marked out and the reporting units be
clearly designated at the top of the column.
7. Additional Parameters - Enter the appropriate parameter .code, name of the
parameter and units of measurement in the space provided.
8. Average, Maximum, Minimum - Enter the average, maximum and minimum
values for the results recorded in the data column. Please note no average is to be
calculated for pH. Any average for Fecal Coliform is to be calculated as a geometric
mean. If you are uncertain about how to calculate the geometric mean, please contact
your local DWQ Regional Office or a member of the NPDES Compliance/Enforcement
Unit staff at [phone]. If only one value is reported for a parameter during the
reporting month, that value should be reported as the average, maximum and minimum.
9. Sample Type - Enter the sample description in each column for which data is
being reported. Enter the letter "C" for composite or the letter "G" for grab.
10. Monthly Limit - Enter the monthly limit for each parameter as found in the
current NPDES permit, Special Order by Consent or Judicial Order by Consent.
III. Facility Status Information
1. Facility Status - Mark the appropriate box to show whether facility was compliant
or noncompliant with regard to permit, SOC or JOC requirements. If noncompliant, use
the comment section to explain in detail the course of action taken or,to be taken to
achieve compliance.
2. Signature of Permittee - Record the name of the permittee or his or her authorized
agent (printed or typed), the dated signature of that person and a mailing address and

phone number at which he or she may be reached during working hours. If someone
other than the permittee is to be the signatory, the requirement noted by the double
asterisk "* *" must be met. Also record the expiration date of the current permit in this
section. While this is not on the form, you may also wish to provide an e-mail address in
this space that can provide the Division with another avenue of communication.
IV. Stream Monitoring Information
1. Stream - Name of the stream from which the upstream or downstream monitoring
samples are taken.
2. Location - Location of the site on the stream from which the sample was taken.
This may be recorded as a distance (e.g. "100 feet upstream of outfall") or a specific
location (e.g. "S.R. 1111 ").
V. General
1. Submitting Reports - An original and one copy of each month's monitoring report is
required to be submitted to the Division of Water Quality's Central Files office
(address listed on form MR-1) and must be received by the Division within thirty (30)
days after the end of the month for which the report is made.
2. Appearance - Forms must be completed in ink. Please make all entries on forms
legible. All information other than signatures must be printed or typed. If you fill out
forms by hand, please make sure the originals are completed in ink and that all entries
are legible. Copies of the original report must also be readable and must include a
reproduction of the backside of the effluent reporting form containing the permittee's
certification. If you utilize a computer -generated report, you must also ensure that the
report is legible and that proper copies are made. DWQ will notify if you are the user
of a form that is deemed deficient and will advise you of what modifications need to be
made.
3. Calculations
(a) Averages. All averages are to be calculated as the arithmetic mean of the
recorded values with the exception of that of Fecal Coliform, which is to be
calculated as a geometric mean. If you are uncertain about how to calculate the
geometric mean, please contact your local DWQ Regional Office or a member of
the NPDES Compliance/Enforcement Unit staff at [phone].
(b) Use of "less than" values. For calculation purposes only, recorded values
of less than a detectable limit (< #.##) may be considered to equal zero (0) for all
parameters except Fecal Coliform, for which values of "less than" may be
considered to be equal to one (1). 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). Please note there is never a case when an average would need to
be recorded along with a "less than" symbol.
(c) Use of "greater than" values. Such values are only expected (and then
only infrequently) in the reporting of Fecal Coliform and BOD. If a "greater than"
value is reported, the numeric portion of the value should be sufficiently high so
as to make the facility aware of the extent of any problems with treatment
efficiency. Upon receipt of "greater than" testing results, a facility should consult
its laboratory to see if changes in testing procedure need to be made in order to
get discreet values from the analysis. For calculation purposes only, the numeric
portion of the value must be used to calculate either an arithmetic or geometric
mean.
4. Enforcement - Failure to comply with any of the requirements listed above'may result
in the facility being issued a Notice of Violation or being subject to other appropriate
enforcement action.
5. Order of Report Forms-DMR submittals typically include the results of monitoring of
the facility's effluent, its influent and its receiving stream. It is requested that for any
DMR, the report be bound with the Effluent page(s) (DWQ form MR-1 or MR- 1.1) on
top, followed by the Influent page (form MR-2, if influent monitoring is required) and
finally the Upstream/Downstream page (form MR-3).
6. Number of Reports -You are required to submit the original and one copy of the report
to DWQ. Each copy should be a discreet report for the month, put together in the order
described above.
7. Multiple Submittals -School systems and contract operations, please take note of this
request. If you submit reports for multiple permits within one mailing, please bind
together the submittals (original and one copy) for the various facilities. Please do not
segregate the reports into any other type of organization (e.g., binding together all
effluent or stream monitoring pages). To do so will cause reports to be taken apart and
placed together properly, which slows processing and introduces opportunity for
mistakes to be made. If you send many DMRs in one envelope, it is advisable that you
send a summary sheet along with the DMRs that lists what reports are contained in the
package.
Permits for Other Program Areas -Please note that this discussion pertains to submittal
of DMRs required of NPDES permittees (point source discharge pipes to streams).
You may have permits for activities in other program areas such as DWQ's non
discharge program (wastewater spray irrigation or land application of residuals) or the
Division of Environmental Health's public water supply program (drinking water).

Please consult those permits for instructions for their submittal. It is not advisable to
submit any other reports along with your DMR submittals.
9. Toxicity Reporting -Some permittees will have monitoring requirements for Toxicity
within their permits. Please be aware that this parameter has a dual reporting
requirement. Results of toxicity testing should be reported on DMR forms, but the
toxicity testing results forms must be submitted to the Aquatic Toxicity Unit at the
address listed below.
Aquatic Toxicology Unit
DWQ Environmental Sciences Branch
1621 Mail Service Center Raleigh, NC 27699-1621
10. Corrected or Amended Reports -In the event that you omit or erroneously report
data on a DMR, the information should be updated with the submittal of an amended
report. To best handle the amended data, the following procedure is recommended:
1. Regenerate or make a copy from your files of the DMR previously submitted to
DWQ.
2. Make changes to the individual data points on the form, including updated
summary information.
3. Initial and highlight changes to the original submittal.
4. At the top of the reporting page, write very conspicuously: "Amended Report" or
"Corrected Report."
5. Provide a short cover page describing the changes to the DMR or note changes in
the comment area on the back of the MR-1 form.
Use of this procedure will be a great help to DWQ's data entry staff. Without
specifically identifying changes on the DMR, each data point must be evaluated
between the original and amended reports to ensure the values in our database are
correct. Calling attention to just those values that are changed both speeds up our
processes and decreases the possibility for errors to be made.
11. Contacts-DWQ deals with a tremendous number of permitted entities that may be
experiencing their own changes involving administration and personnel. In dealing with
NPDES permit matters, DWQ must deal with only one representative of the permitted
facility (someone with authority to see that changes are made at the facility if they are
necessary) in order to be effective. You are encouraged to keep DWQ informed of any
updates as to the person responsible for the permit, addresses or phone numbers in order
to facilitate the best possible communication between our two organizations. This can be
done by sending an e-mail to our Unit or by using the back of the MR-1 form under the
permittee certification section. Regulations regarding who may be deemed responsible
for a permit and who may sign as the "permittee" on the DMR can be found

(respectively) in the North Carolina Administrative Code in sections 15A NCAC 2H
.106(e) and 15A NCAC 2B .0506 (b)(2).

Attachments: 10_30_12_ATU Recommendations WTP Strategy.pdf
Hi Derek,
First, my apologies as I was supposed to get back to you about this when we talked in September.
From my notes, it looks as though Cindy Moore and Bob Guerra talked in 2010 and changed their toxicity test from
Ceriodaphnia 7-day pass/fail to Fathead Minnow acute 24 hour test at 90% because the facility only discharges about
once every 2 weeks. To perform a chronic test, the facility must discharge at least twice a week. Chronic tests were
really designed for facilities that discharge every day. I see from their records that they sometimes go for months
without discharging.
However, in 2012, we came up with a policy for Water Treatment Plants that don't discharge at a frequency that will
allow chronic testing —we assign them acute Ceriodaphnia dubia testing for 48 hours at 90%. We chose this test
because it is the most stringent acute test that we assign. I have attached the memo from 2012 regarding this policy. So
far, only one facility has been assigned this test —Ramseur WTP (NC0074454).
So, following this policy, please assign them acute Ceriodaphnia dubia 48 hr pass t 90%. This will be code
TGA313 (short description is Ceri48PF).
Another note for their records ... they never did the Ceriodaphnia dubia chronic test. It looks like they continued using
the code for Ceriodaphnia pass/fail on their DMR (TGP3B) for all of 2010 and 2011, but all the tests they submitted to us
for this time are Fathead 24 hr pass/fail (TGE6C).
I don't think they should be allowed to apply for the general permit until they submit 12 data points with the
Ceriodaphnia 48 hr pass/fail.
If you need anything else for this facility or other WTP info, please let me know.
Thanks,

Subject: Draft permit City of Marion WTP NC0055221 toxicity question.
Carol,
Julie Grzby and I spoke with you on the phone about the City of Marion WTP NC0055221 toxicity tests back in
September.
My hotes say to change aquatic toxicity monitoring to Acute — Ceriodaphnia (48 hour or 24 hour)?
If I follow our strategy, it should be chronic Ceriodaphnia dubia performed as 7-day pass/fail at 14% since IWC is
>0.25%. The permit was modified in February 2010 with acute toxicity monitoring with Flathead Minnow TGE6C at
90%. 1 don't know why 90% was used in the past when the IWC based on a 7Q10 of 3.6 cfs is 13.8% (see RPA). What I
do know from the file is that the permittee requested the modification.
My notes also say that they need two more tests to be considered for the general permit. We have received the
October results but it has not been entered to BIMS yet (see attached data).
I have attached the draft permit that I plan to public notice on December 17 for your review. In the draft I followed the
Aquatic Toxicity strategy (June 11, 2012) Chronic Ceriodaphnia dubia performed as 7-day pass/fail test at 14% (TGP3B).
can replace this with whatever you decide.
I am uncertain where to go from here. Let me know how to proceed with toxicity monitoring for this permit or if there is
any possibility of issuing the general permit at this point.
Thanks,
Derek

MEMORANDUM
To: Water Treatment Plant Workgroup and NPDES Permitting Unit
From: Cindy A. Moore, Aquatic Toxicology Unit
Carol Hollenkamp, Aquatic Toxicology Uni `1F
Subject: Changes to the Toxicity Testing Requirements in the Water Treatment Plant Permitting Strategy
(October 2009)
The Aquatic Toxicology Unit (ATU) recommends assigning acute 48 hour Ceriodaphnia dubia Pass/Fail testing at 90%
for water treatment plants (WTP) that have an Instream Waste Concentration (IWC) >_ 0.25% but discharge at a
frequency and duration that do not enable chronic sampling according to either the North Carolina Ceriodaphnia
Chronic Whole Effluent Toxicity Procedure or according to Section 8.3, in EPA-821-R-02-013. This assignment would
only be approved for WTPs, after it has been determined that the normal, operational discharge of the facility does
not enable chronic sampling. Suggested permit language is provided on page 3. An updated Table 5.2 of the Water
Treatment Plant Permitting Strategy (October 2009) is provided below. Alternate test assignments, such as the
application of an acute to chronic ratio in the situation of small IWCs, may be considered on a case by case basis
depending on the specific characteristics of the facility's discharge and receiving stream. Any alternate test
assignments must be approved by ATU. If you have any questions, please contact Cindy Moore or Carol
Hollenkamp.

2If discharge is to a lake or lake arm where 7Q10 estimate is not meaningful, the IWC will be incalculable.
IIf the facility's regular operational discharge is at a frequency and duration that do not enable chronic sampling, acute 48-hr
Ceriodaphnia Pass/Fail at 90% may be assigned. This will revert to a chronic testing assignment if it is determined by DWQ that a
chronic schedule can be met.
°For saltwater classified streams, a fathead minnow may be assigned for acute tests if the salinity of the receiving stream at the point of
discharge is <5 ppt throughout the tidally influenced cycle.
Rationale
Water Treatment Plant (WTP) discharge schedules are dependent on the demand for drinking water and are often
more irregular, less frequent and less consistent than Waste Water Treatment Plant (WWTP) discharge schedules.
Per the DWQ WET Strategy Memo (August 2, 1999) and EPA guidance in the Technical Support Document for
Water Quality -based Toxics Control (TSD), facilities with an IWC >_ 0.25% should be assigned chronic testing. In
some situations, sampling a WTP discharge to meet a chronic testing schedule may not be possible. If a WTP
discharges only once a week, they will not be able to meet a chronic toxicity sampling schedule. If a WTP discharges
twice a week, they will need to discharge on a Tuesday and Thursday to meet North Carolina's Ceriodaphnia Chronic
Whole Effluent sampling schedule. Alternatively, they would need to discharge 2 days a week, at approximately 48
hours apart, and hire a NC certified laboratory to perform a specialized testing schedule that would be markedly
different than the laboratory's regular testing schedule for NC Chronic Tests. in order to meet EPA's testing
schedule, they would need to discharge 3 times a week, with the discharges spaced approximately 48 hours apart.
Therefore, WTP's that discharge at a frequency and duration that do not enable chronic sampling according to
either the North Carolina's Ceriodaphnia Chronic Whole Effluent Toxicity Procedure or Section 8.3 in EPA-821-R-02-

013 will either 1.) simply not be able to perform a chronic test; or 2.) in attempting to meet a chronic test schedule
the facility's regular operation would require modification and potentially cause undue financial burden. In these.
cases, ATU recommends assigning an acute 48 hour Ceriodaphnia Pass/Fail testing at 90% effluent. An acute
pass/fail test assignment at 90% effluent and 48 hour duration is the most stringent of the acute testing
assignments under North Carolina protocol. The use of an acute testing assignment in this situation is similar to the
application of an acute pass/fail test assignment at 90% when the Instream Waste. Concentration (IWC) is
incalculable. Alternate test assignments, such as the application of acute to chronic ratio in the situation of small
IWCs, may be considered on a case by case basis depending on the specific characteristics of the facility's discharge
and receiving stream. Any alternate test assignments must be approved by ATU.
The need for a modified testing assignment for facilities that cannot meet a chronic discharge schedule appears to
be limited to WTPs at this point. However, this need is not unique to North Carolina. Both Florida and Colorado
have policies which specify acute testing assignments in situations where chronic test schedules cannot be met or
when the discharge is not considered a chronic exposure. This testing assignment is not specific to WTPs in either of
these state policies. The Florida Administrative Code, Chapter 62-620.620 (3) (f) states: "Facilities with intermittent
discharges at frequencies and durations that do not enable sampling according to Section 8.3, in Methods EPA-821-
R-02-013 and EPA-821-R-02-014 shall be required to conduct acute definitive tests starting with 100% effluent and
using a minimum of five dilution concentrations in accordance with paragraph 62-620.620(3)(h) F.A.C. Chronic
definitive tests shall not be required." The Colorado Water Pollution Control Program Policy for Whole Effluent
Toxicity (WET) testing Section III, Part 2 (c), states: "Where the discharge is intermittent, as defined below, acute
WET testing maybe substituted for chronic WET testing. The basis for this is that there would not be chronic
exposure of aquatic life to the effluent". Definitions of Intermittent Discharges include: "A) the maximum discharge
frequency is less than 3 consecutive days (72 hours), and less than 3 days per 7 day period, and less than 10 days
total per month"; and " B) the maximum discharge frequency is less than 5 consecutive days (120 hours) and less
than 5 total days per month."
In summary, ATU considers the assignment of acute pass/fail 48 hour Ceriodaphnia toxicity testing for WTPs that
cannot meet a chronic testing sampling schedule as the most protective step North Carolina can take while still
sampling a facility as close to its normal operational schedule as possible. The inclusion of toxicity testing in WTP
permits has been a process that has evolved over the last decade, so the need for an alternative testing assignment
was not needed previously. DWQ will include language in the permit that will enable a re -opening of the permit and
assignment of"chronic testing if it determined that a WTP discharge schedule can support chronic test sampling.

ACUTE TOXICITY PASS/FAIL MONITORING FOR WATER TREATMENT PLANTS (QUARTERLY)
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 Ceriodaphnia dubia 48 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). Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The tests will be performed during the months of ,
and These months signify the first month of each three month toxicity testing quarter assigned to the
facility.
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 TGA3B. Additionally, DWQ Form AT-
2 (original) is to be sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center
Raleigh, North Carolina 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. 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
Quality indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate
monitoring requirements or limits.
Should it be determined by the North Carolina Division of Water Quality that the facility's discharge frequency and
duration enable chronic sampling according to either the North Carolina Ceriodaphnia Chronic Whole Effluent Toxicity
Procedure or to Section 8.3, in Methods EPA-821-R-02-013, the permit may be re -opened and modified to include chronic
toxicity tests.
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
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.

Facility Summary
This facility is a conventional technology water treatment plant [coagulation, flocculation, sedimentation,
and filtration] with discharge of wastewaters from media filter backwash and sedimentation basins with a
design potable flowrate of 4.0 MGD and a maximum monthly average wastewater discharge of
0.373 MGD. Because the waste flow is >50k gpd, continuous flow monitoring is required. The facility
consists of the following water and wastewater treatment units:
• stilling well
• flash mixer
• over and under Flocculator
• settling basins
• multi -media filters
• 200,000 and 1,000,000 gallon clear wells
• - two (2) sludge lagoons
• chemical usage consists of
o alum
o fluoride
o soda ash

Monthly ay verage FLOW (MGD) — Last 36 months that flow was reported Sept2011-Aug2014:
[Ave 0.271 MGD; Maximum, Monthly average flow = 0.373 MGD]
Eli ig bility for Coverage Under the General Permit NCG590000 — The Marion WTP is not eligible for the
general permit because there is not enough toxicity data. At least two (2) samples as Whole Effluent
Toxicity (WET) testing with testing of acute Ceriodaphnia dubia performed as 48 hour pass/fail test at 90%
effluent concentration are needed to determine eligibly.
Toxici —Whole Effluent Toxicity (WET) testing is assigned with testing of acute Ceriodaphnia dubia
performed as 48 hour pass/fail test at 90% effluent concentration, during January, April, July and October
[See A. (2.)] because the facility discharges about once every 2 weeks. To perform a chronic test, the
facility must discharge at least twice a week. This test was chosen because it is the most stringent acute test
available. In the past 4 and a half years (April 2010-July 214) this facility has passed-11 Acute Pimephales
(Flathead Minnow) performed as static 24 hour Pass/Fail tests (TGE6C).
For Renewal —This permit reflects discharge at Outfall 001. DWR updated the facility description and
Map; added parameter codes to Section A. (1.); added Electronic Reporting - Discharge Monitoring
Reports page [Section A. (2.)]; changed flow monitoring to Continuous and Recording; assigned Whole
Effluent Toxicity (WET) testing with testing of acute Ceriodaphnia dubia performed as 48 hour pass/fail
test at 90% and removed Total Iron monitoring.
Stream — Discharge from WTP for outfall 001 is into the an unnamed tributary to Nix Creek [Stream
Segment 11-20]. The segment is not currently listed in the 2012 North Carolina 303(d) List.
RPA — A Reasonable Potential Analysis (RPA) was conducted on Copper, Fluoride, Aluminum and Iron
effluent parameters data because Discharge Monitoring Reports (DMRs) reported concentration above
method -detection levels (MDLs) for the past four and one half (4 1/2) years (Mar2010-Aug2014). [See
attached RPA summary sheets.]
• Iron did not show reasonable potential to violate state water quality standards (WQS). No
monitoring is required.

Fotenotes:
1. No later than 270 days from the effective date of this permit, begin submitting discharge monitoring reports electronically using NC DWR's eDMR application system. See Special Condition A. (3.).
2. The Town will have 18 months from the effective date of this permit to install a continuous flow meter. Until then instantaneous measurements can be taken with the duration of discharge to be
noted in log books and a total daily discharge reported on the DMR.
3. The Division shall consider TRC effluent values reported below 50 µg/L to be compliant with the permit. However, the Permittee shall continue to record and submit all values reported by a North
Carolina -certified laboratory method (including field certified), even if these values fall below 50µg/L.
4. Samples shall be collected concurrently with WET -test samples.
5. Whole Effluent Toxicity (WET) testing - testing of Ceriodaphnia dubia shall be performed as 7-day pass/fail test at 14% effluent concentration, during January, April, July and October [See A. (2.)].
