Subject: Draft of NPDES Permit NC0087866
John F. Kime WTP
Randolph County
Grade I Physical Chemical WPCS
Dear Mr. Flory:
The Division has reviewed your request to renew the subject permit. Please review this draft carefully to ensure a
thorough understanding of the information,conditions,and requirements it contains.
This draft contains the following major changes from the existing permit:
• The Supplement to Cover Sheet has been updated with the new maximum monthly average discharge.
• The facility grade has been added to Section A. (1).
• Section A.(5)has been updated regarding electronic submission of effluent data. Federal regulations
require electronic submittal of all discharge monitoring reports (DMRs).
• Section A(3)has been added due to a history of failed WET tests. The Division is aware the facility is
looking into this issue.
• The Whole Effluent Testing outlined in Section A. (4)has been updated to Pass/Fail per the Division's
2020 strategy.
• The Wastewater Treatment Components listed on the Supplement to Permit Cover Sheet have
been updated per the facility contact.
• The outfall components on the map have been updated per the facility contact.
• Turbidity limits have been removed as the receiving waters are not impaired for turbidity.
Monitoring is retained.
• The parameters of Sulfate, Bromine, Chloroform, Quinoline, Strontium, Vanadium, and Nitrate-
Nitrite have been added for monitoring in section A. (1)due to being marked "believed present"
in the application. These parameters will be reevaluated in the next permit cycle. If the
parameters have consistently produced no-detect results, this reevaluation may lead to removal
of the monitoring requirement for these parameters.
With this notification,the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Randolph County area,per EPA requirements. Please provide your
comments,if any,to me no later than 30 days after receiving this draft permit.
Following the 30-day public comment period,the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning the draft,please contact me via
e-mail at [e-mail] or via phone at 919-707-3600.

Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the Division's eDMR system
[see A. (5)].
2. 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.
3. Zinc should be monitored if the Permittee adds zinc orthophosphate as a corrosion inhibitor prior to
backwashing.
4. The parameters of Sulfate,Bromine,Chloroform,Quinoline, Strontium,Vanadium,and Nitrate-Nitrite
have been added for monitoring due to being marked"believed present"in the application. These
parameters will be reevaluated in the next permit cycle.If the parameters have consistently produced no-
detect results,this reevaluation may lead to removal of the monitoring requirement for these parameters.
5. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals
(cadmium,copper,lead,nickel, silver, and 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 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. Ceriodaphnia dubia 7 day pass/fail test @ 90%concentration. See Condition A. (4.)for toxicity testing
requirements. Toxicity testing should be performed during the months of January,April,July,and October.
All samples must be collected from a typical discharge event.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN
TRACE AMOUNTS.
A. (2.) PERMIT RE-OPENER: NUTRIENT MONITORING
[G.S. 143-215.1(b)]
Pursuant to N.C. General Statutes Section 143-215.1 and the implementing rules found in the North
Carolina Administrative Code at 15A NCAC 2H.0112 (b) (1) and 2H.0114 (a) and Part II sections B-12
and B-13 of this permit,the Director may reopen this permit to require supplemental nutrient monitoring
of the discharge. The purpose of the additional monitoring will be to support water quality modeling
efforts within the Cape Fear River Basin and shall be consistent with a monitoring plan developed
jointly by the Division and affected stakeholders. In addition, the results of water quality modeling may
require that limits for Total Nitrogen and Total Phosphorus be imposed in this permit upon renewal.
A. (3.) PERMIT REOPENER: WHOLE EFFLUENT TOXICITY
Page 4 of 9

Permit NC0087866
[G.S. 143-215.1(b)]
Whole Effluent Toxicity monitoring results indicating aquatic toxicity may result in the Division of Water
Resources re-opening this permit or requesting by letter that further action be taken. Additional metals testing, a
toxicity identification evaluation,a toxicity reduction evaluation, and/or an assessment of discharge treatment
alternatives may be requested.
A. (4.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0500 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 90%.
The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in
the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," (Revised December 2010, or
subsequent versions) or"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure"
(Revised December 2010, or subsequent versions). 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.
The effluent concentration defined as treatment two in the procedure document is 90 %. The testing
shall be performed as a Ceriodaphnia dubia 7-day pass/fail test.
If the test procedure performed as the first test of any single quarter results in a failure or ChV
below the permit limit,then multiple-concentration testing shall be performed at a minimum, in
each of the two following months as described in "North Carolina Phase II Chronic Whole
Effluent Toxicity Test Procedure" (Revised-December 2010, or subsequent versions).
All toxicity testing results required as part of this permit condition will be entered electronically using
the Division's eDMR system for the months in which tests were performed, using the parameter code
TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally, DWR Form AT-3
(original) is to be sent to the following address:
North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,NC 27699-1621
Or, results can be sent to the email, ATForms.ATBAnc.deq.gov.
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, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate

Permit NC0087866
signature. 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, monitoring
will be required during the following month. 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 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.
A. (5.) ELECTRONIC REPORTING - DISCHARGE MONITORING REPORTS
[G.S. 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program
reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December
21, 2015.
