Subject: Draft NPDES Permit Renewal
Permit NC0020231
Tar River WRF
Franklin County
Grade IV Biological WPCS
SIC Code 4952
Dear Mr. Franklin:
Enclosed with this letter is a copy of the Draft NPDES permit renewal for your facility. Please
review this draft carefully to ensure thorough understanding of the requirements and conditions it
contains.There are several changes from the existing permit,including the following:
• Per 15A NCAC 08G .0302, the facility class has been changed to Grade IV due to the
nutrient limits in the permit and the rule conditions.
• As the facility class has been updated,monitoring frequencies for pH and dissolved oxygen
have been revised to reflect a Grade IV facility[See A.(1.)].
• Based on NPDES guidance regarding the reduction of monitoring frequencies in NPDES
permits for exceptionally performing facilities,monitoring requirements for CBOD5,NH3-
N, Total Suspended Solids and Fecal Coliform have been reduced to twice per week [See
A.(1.)].
• Based on the Mercury TMDL evaluation showing no annual average mercury
concentration greater than the Water Quality-Based Effluent Limit,the total mercury limit
has been removed from the permit [See A.(1.)]. However, monitoring for mercury using
the low-level test method 1631E shall continue when performing the three Effluent
Pollutant Scans[See A. (6.)]
• Based on the 2012 Statewide Mercury TMDL implementation guidance,Special Condition
A.(8.)Mercury Minimization Plan has been removed from the permit.
• Some of the wording has changed in Special Condition A.(2.), Chronic Toxicity Permit
Limit,please review each paragraph carefully.
• Special Condition A.(3.)has been modified to include the specific three years in which the
Effluent Pollutant Scan shall be performed(2022,2023,and 2024). In addition,at the end
of the Special Condition, 2nd species Toxicity Testing Requirements for municipal permit
renewals per Federal Regulations [40 CFR 122.21(j)(5)] have been added.
• A notation was made concerning the Electronic Reporting Rule—Phase 2 Extension.EPA
is proposing to extend the Phase 2 deadline from December 21, 2020, to December 21,
2025.The current compliance date will be extended if the implementation date is extended
as a fmal regulation change in the federal register.

The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Ceriodaphnia dubia at an effluent concentration of 13%.
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
March,June,September,and December.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.
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:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1621 Mail Service Center
Raleigh,North Carolina 27699-1623

Permit NC0020231
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. (3.) CALCULATION OF TOTAL NITROGEN AND TOTAL PHOSPHORUS LOADS
[G.S.143-215.1(b)]
(a.)The Permittee shall calculate monthly and annual TN Loads as follows:
(i.) Monthly TN(or TP)Load (lb/mo)=TN (or TP) x TMF x 8.34
where:
TN or TP = the average Total Nitrogen or Total Phosphorus concentration
(mg/L)of the composite samples collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the
month(MG/mo)
8.34 = conversion factor,from (mg/L x MG)to pounds
(ii.) Annual TN (or TP) Load (Ib/yr) =Sum of the 12 Monthly TN(or TP)Loads for the
calendar year
(b.)The Permittee shall report monthly Total Nitrogen and Total Phosphorus results(mg/L and lb/mo)
in the appropriate discharge monitoring report for each month and shall report each calendar year's
results(lb/yr)with the December report for that year.
A. (4.) ANNUAL LIMITS FOR TOTAL NITROGEN OR TOTAL PHOSPHORUS
[15A NCAC 02B .0730]
(a.) Total Nitrogen(TN)and Total Phosphorus(TP)allocations and load limits for NPDES
dischargers in the Tar-Pamlico River basin are annual limits and apply on a calendar year basis.
(b.) For any given calendar year,the Permittee shall be in compliance with the annual TN(or TP)
Load limit in this Permit if:
(i.) the Permittee's annual TN(or TP)Load is less than or equal to the effective limit,or
(ii.) the Permittee is a Co-Permittee Member of a compliance association.
(c.) If the Permittee is not a co-permittee member of a compliance association and the Permittee's
cumulative annual TN(or TP)discharge exceeds the effective TN(or TP)Load limit in this permit
at any point during the calendar year,the Permittee is in violation of its TN(or TP)Load limit for
the remainder of the calendar year,and each day of continuing violation shall constitute a
separate violation.Compliance with annual limits shall be determined separately for each
calendar year,and an exceedance in one year does not carry forward to subsequent years.

Permit NC0020231
(d.) The TN(or TP)Load limit in this Permit(if any)may be modified as the result of allowable
changes in the Permittee's allocations.
(i.) Allowable changes include those resulting from purchase of TN(or TP)allocation from an
authorized mitigation banker,the Ecosystem Enhancement Program,or other source
allowed under applicable regulations;purchase,sale,trade,or lease of allocation between
the Permittee and other dischargers;and other transactions approved by the Division and
consistent with the Tar-Pamlico River Basin Association Agreement,as revised.
(ii.) The Permittee may request a modification of the TN(or TP)Load limit in this Permit to
reflect allowable changes in its allocation(s).Upon receipt of timely and proper application,
the Division will modify the permit as appropriate and in accordance with state and federal
program requirements.
Changes in TN(or TP)limits become effective on January 1 of the year following permit
modification.The Division must receive application no later than August 31 for changes
proposed for the following calendar year.
(iv.) Application shall be sent to:

1 of a given year,its TN and TP discharges during that year are governed by that association's
group NPDES permit and the limits therein.
(i.) The Permittee shall be considered a Co-Permittee Member for any given calendar year in
which it is identified as such in Appendix A of the association's group NPDES permit.
(ii.) Association roster(s)and members'TN and TP allocations will be updated annually and in
accordance with state and federal program requirements.
(iii.) If the Permittee intends to join or leave a compliance association,the Division must be
notified of the proposed action in accordance with the procedures defined in the
association's NPDES permit.
(A) Upon receipt of timely and proper notification,the Division will modify the permit as
appropriate and in accordance with state and federal program requirements.
(B) Membership changes in a compliance association become effective on January 1 of the
year following modification of the association's permit.

A. (5.) NUTRIENT ALLOCATIONS
[15A NCAC 02B.0730]
(a.) Total Nitrogen(TN)and Total Phosphorus (TP)allocations represent the maximum TN and TP
loads that a discharger or group of dischargers is potentially allowed under the Tar-Pamlico
nutrient management strategy.Allocations are not enforceable limits but are the basis for TN and
TP limits established in individual or group NPDES permits.
(b.) The allocations originally assigned to the Tar-Pamlico Basin Association members total 889,274
lb/yr(404,274 kg/yr)TN and 160,372 lb/yr(73,060 kg/yr)TP.These group allocations have been
divided among the members in proportion to the maximum permitted flow in each member's
permit;that is,
Individual Permitted Flow
Individual Allocation(TP or (MGD) x Group Allocation,TPBA (TN
TN)= Total Permitted Flow,TPBA or TP)
(MGD)
For the purposes of this distribution,individual permitted flows for the Association members are those
in effect as of July 2014 and result in a Total Permitted Flow of 62.495 MGD.
(c.) The following table lists,for information purposes only,the TN and TP allocations assigned to,
acquired by,or transferred to the Permittee in accordance with the Tar-Pamlico River Basin Phase
IV Agreement.Applicable TN or TP limits are established in the Effluent Limitations conditions
of this permit or in the NPDES pe ++it of a compliance association of which the Permittee is a Co-
Permittee
Member.

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

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.
