Permitting Unit
The Town of La Grange recently received its renewed NPDES Permit (NC0021644) that becomes effective April 1, 2019
and expires March 31, 2024. Under the new permit, the Town qualifies for reduced monitoring (2 days per week) and as
a result, respectfully requests that Permit WQ0034386 be amended to allow reduced monitoring under that permit as
well. For you records, I have attached the Town's new NPDES Permit to substantiate the facts and support our request
for reduced monitoring.
I appreciate your time and consideration of this request. Should you have any questions or require any additional
information, please do not hesitate to contact James W. Sutton at iwsutton@ lagrangenc.con or [phone].
Respectfully,

Subject: Issuance of NPDES Permit NCO021644
La Grange WWTP
Grade IV Biological WPCS
Lenoir 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.
The Division understands that you have made no significant changes to your facility since the last permit
renewal. We have made the following updates for the permit renewal:
1. Regulatory citations have been added to the permit.
2. The facility map has been updated.
3. The facility classification Grade IV Biological Water Pollution Control System has been added to
the effluent page.
4. Total Phosphorus (TP) effluent limits have been changed from Monitor & Report to 2.0 mg/L
(weekly average) per the Neuse Permitting Summary Feb 2013.
5. Section A. (7.) has been added to reflect current language regarding electronic submission of
effluent data. Federal regulations require electronic submittal of all discharge monitoring reports
(DMRs).
6. 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, 2016 with some exceptions. The NC
Division of Water Resources 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 Division will need site -specific effluent hardness
data and instream hardness data, upstream of the discharge, for each facility monitoring these
metals in order to calculate permit limitations. The metal of concern for this permit renewal is
Zinc.
To evaluate dissolved Zinc, a Reasonable Potential Analysis (RPA) was conducted using data
reported on DMRs from November 2015 to March 2018. Results indicated a reasonable potential

to exceed both the Acute and Chronic allowable concentrations for Zinc, 125.7 µg/L and 126.7
µg/L, respectively. The Acute value is typically used as the daily maximum limit and Chronic
value is typically used as the monthly average limit. However, the Chronic value for Zinc is less
stringent. The monthly average limit must be more stringent or equal to the daily maximum limit.
Therefore, the daily maximum limit and monthly average limit for Zinc will be the Acute value as
follows:
Parameter Outfall Monthly Average Limit Daily Maximum Limit
Zinc 001 125.7 µg/L 125.7 µg/L
Please note that on May 29, 2018 additional information was requested for Total Hardness. The
total hardness data should have included five (5) days of Total Hardness (CaCO3 or (Ca + Mg))
data for the effluent and upstream of Outfall 001. This data would have been used in a
recalculation of Zinc limits for the draft permit. However, no response was received within 60
calendar days [per 15A NCAC 211.0107(b)]. Therefore, the permit renewal was drafted without
the benefit of the requested Hardness data. Therefore, a default hardness of 25 mg/L was used to
calculate effluent limits for Zinc as indicated above.
7. A schedule of compliance [Section A. (3.)] has been added for the Total Zinc limits in Section A.
(L). Compliance with this limit shall commence on April 1, 2023, approximately 48 months form
the permit effective date.
8. Effluent and upstream quarterly monitoring for Total Hardness have been added.
Division personnel have reviewed and approved your permit modification request to reduce the
effluent and influent monitoring frequencies for Biochemical Oxygen Demand (BOD5), Total
Suspended Solids (TSS), Ammonia, and Fecal Coliform from daily to 2/week monitoring. The
modification was based upon an evaluation of three years of facility effluent monitoring data. The
facility's performance satisfies the criteria established in the "DWQ Guidance Regarding the
Reduction of Monitoring Frequencies in NPDES Permits for Exceptionally Performing Facilities"
as approved by the Director of the Division of Water Resources on October 22, 2012 and justifies
reduced monitoring for these parameters. Please note that additional NPDES permit requirements
will include:
• Eligible facilities may be granted a reduction from existing permit monitoring
frequencies to a 2/week minimum frequency for the four target parameters. Reductions
will be made for both effluent and influent sampling.
• Where monitoring is reduced to twice per week, it must occur on any two non-
consecutive days during the calendar week (Sunday through Saturday).
• Required monitoring frequency reductions establish new permit minimums for
monitoring. As always, facilities may monitor more often than required in the permit.
• If a reportable event, as defined by the permit [e.g., Part II (E) (6 & 9)] occurs, any
facility granted reduced monitoring frequencies will be encouraged to monitor on a daily
basis until the episode is resolved.
10. Total Mercury must be monitored once during the permit cycle. Mercury monitoring is included
to provide a database for future mercury management and TMDL evaluation. See Special
Condition A. (2.).
Please note that DMRs may need to be amended based on the information below. The following was
noted from review of DMR data for the period Oct2015 to Sep2018 (3 years) for this permit renewal:

• Monthly TN loading should be reported 12 times a year. Reporting of Monthly TN Loading for
February, March and April is missing.
• Data was reported as zero (0) for Ammonia, BOD, Fecal Coliform, and TSS. Reporting zero for
any parameter, with few exceptions such as temperature, is inadequate reporting. The method
PQL should be reported along with the data modifier "less than" (<) instead of zero. Minimum
detection and reporting levels (MDLs & PQLs) are defined by the DWR Water Sciences Section
as follows:
Each analytical procedure has a Practical Quantitation Limit (PQL), which is defined as
"the lowest concentration that can be reliably achieved within specified limits of
precision and accuracy during routine laboratory operating conditions." PQLs are
subjectively set at some multiple of typical Method Detection Limits (MDLs) for reagent
water (generally 3 to 5 times the MDL). The PQL for a procedure may also be defined
by: a reporting limit or minimum limit (NIL) specified by the analytical method; sample
volume and buret graduations; and/or minimum measurement values that are method -
defined. The established PQL for a procedure serves as a reliable and routinely
achievable reporting limit for a biological or chemical parameter
(http s:Hdeq.nc. gov/about/divisions/water-resources/water-resources-data/water-sciences-
home-page%microbiology-inorganics-branch/methods-pad is-qa).
In accordance with NPDES Standard Conditions Part H Section D. 4., the following is required
for test procedures:
To meet the intent of the monitoring required by this permit, all test procedures must produce
minimum detection and reporting levels that are below the permit discharge requirements and
all data generated must be reported down to the minimum detection or lower reporting level
of the procedure. If no approved methods are determined capable of achieving minimum
detection and reporting levels below permit discharge requirements, then the most sensitive
(method with the lowest possible detection and reporting level) approved method must be
used.
• Units of Measure (UoM) — mg/L vs. µg/L: For Total zinc please carefully report the correct units
of measurement in eDMR. When your contract lab report results in mg/L the conversion is to
µg/L is to multiply by 1000. When converting from µg/L to mg/L the result is divided by 1000.
Please report results for Zinc in µg/L for consistency with permits limits.
• For 2016, annual TN loading (parameter code QY600) was reported in February 2016. For 2018
the yearly parameter QY600 for yearly TN was reported 6 times. This parameter QY600 should
only be reported once per year in December. The parameter code QM600 should be used for
monthly reporting of TN.
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.

A. (1.) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS (continued)
[15A NCAC 02B.0400 et seq., 15A NCAC 02B.0500 et seq.]
Footnotes:
1. The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR
application system. (See A. (7.).)
2. Sample Locations: E — Effluent, I — Influent, U — Upstream at NCSR 1540, D 1 — Downstream at NCSR 1518,
D2 — Downstream at NCSR 1327.
3. TN Load is the mass quantity of Total Nitrogen (TN) discharged in a given period of time and requires Total
Monthly Flow (TMF). See Special Condition A. (4.), Calculation of TN Load.
4. The monthly average effluent BOD5 and TSS concentrations shall not exceed 15% of their respective influent
value (85% removal).
5. Total Residual Chlorine (TRC) compliance is required for chlorine or chlorine derivative used for
disinfection. 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.
6. Instream samples shall be collected three times per week (3/week) during the months of June through
September and once per week (1/week) the remainder of the year. Instream monitoring is provisionally
waived based on the Town of La Grange's membership in the Lower Neuse River Basin Association
(LNBA). If at any time during the term of this permit, membership in the LNBA is terminated, the Permittee
shall notify the Division immediately, and immediately begin conducting instream monitoring as stipulated in
this permit.
7. For a given wastewater sample, TN = TKN + (NO3-N + NO2-N), where TN is Total Nitrogen, TKN is Total
Kjeldahl Nitrogen, and (NO 3-N + NO2-N) are nitrate and nitrite nitrogen, respectively.
8. Compliance with this limit shall be determined in accordance with Special Condition A. (5.) of this permit,
Annual Limits for Total Nitrogen.
9. Compliance with this limit shall commence on April 1, 2023, approximately 48 months form the permit effective
date. See Compliance Schedule Condition A. (3.).
10. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals (Zinc).
11. 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 Water Quality Permitting Section 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.
12. Mercury must be monitored once during the permit cycle. See Special Condition A. (2).
(b.) There shall be no discharge of floating solids or visible foam in other than trace amounts.
A. (2.) EFFLUENT MERCURY ANALYSIS [G.S. 143-215.1(b)]
The permittee shall provide in the next permit renewal application, at least one effluent mercury analysis using EPA
Method 1631E. This mercury sample must be taken within 12 months prior to the application date. Any additional
effluent mercury samples taken from the effective date of the permit until the application date shall also be submitted
with the renewal application. The mercury analysis must be provided with the application, or the application may
be returned as incomplete and the permittee considered non -compliant.

NPDES Permit NCO021644
A. (3.) SCHEDULE OF COMPLIANCE (OUTFALL 001)
[G.S. 143-215.1(b)]
1. Within one year from the effective day of the permit the Permittee shall submit to the Division of Water
Resources a Corrective Action Plan summarizing the actions to be taken to achieve compliance with the Total
Zinc limits at Outfall 001 and a schedule of activities to implement the Plan.
2. Within two years from the effective date of the permit submit a report to the Division summarizing actions
taken in accordance with the Corrective Action Plan.
3. Within three years from the effective date of the permit submit a report to the Division summarizing actions
taken in accordance with the Corrective Action Plan.
4. Within four years from the effective date of the permit submit a report to the Division summarizing actions
taken in accordance with the Corrective Action Plan.
5. Achieve compliance with Total Zinc limits specified in Section A. (2.) by April 1. 2023.
Upon approval of the Corrective Action Plan by the Division, the report and actions become an enforceable part
of this permit. Any modifications to the schedule shall be requested to the Division at least ninety (90) days
before the deadline. Modifications to the schedule in excess of four months will be subject to public notice.
A. (4.) CALCULATION OF TOTAL NITROGEN LOADS
[G.S. 143-215.1(b)]
(a.) The Permittee shall calculate monthly and annual TN Loads as follows:
(i.) Monthly TN Load (pounds/month) = TN x TMF x 8.34
where: TN = the average Total Nitrogen concentration (mg/L) of the composite samples
collected during the month
TMF = the Total Monthly Flow of wastewater discharged during the month
(MG/month)
8.34 = conversion factor, from (mg/L x MG) to pounds
(ii.) Annual TN Load (pounds/year) = Sum of the 12 Monthly TN Loads for the calendar year
(b.) The Permittee shall report monthly Total Nitrogen results (mg/L and pounds/month) in the appropriate
discharge monitoring report for each month and shall report each year's results (pounds/year) with the
December report for that year.
A. (5.) ANNUAL LIMITS FOR TOTAL NITROGEN
[G.S. 143-215.1(b)]
(a.) Total Nitrogen (TN) allocations and TN Load limits for NPDES dischargers in the Neuse River basin apply
on a calendar year basis.
(b.) For any given calendar year, the Permittee shall be in compliance with the annual TN Load limit in this
Permit if:
(i.) the Permittee's annual TN discharge is less than or equal to its TN Load 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 discharge exceeds the effective TN Load limit in this permit at any point during the calendar
year, the Permittee is in violation of its TN Load limit, and each day of a continuing violation shall
constitute a separate violation.
(d.) The TN Load limit in this Permit (if any) may be modified as the result of allowable changes in the
Permittee's TN allocation.
(i.) Allowable changes include those resulting from purchase of TN allocation from the Wetlands
Restoration Fund; purchase, sale, trade, or lease of allocation between the Permittee and other
dischargers; regionalization; and other transactions approved by the Division.

A. (5.) ANNUAL LIMITS FOR TOTAL NITROGEN (continued)
[G. S. 143-215.1(b)]
(ii.) The Permittee may request a modification of the TN Load limit in this Permit to reflect allowable
changes in its TN allocation. Upon receipt of timely and proper application, the Division will modify
the permit as appropriate and in accordance with state and federal program requirements.
(iii.) Changes in TN 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

Monitoring Reports
1. Reporting Requirements I Supersedes Section D. 2. and Section E. 5. a
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
• 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).

A. (7.) ELECTRONIC REPORTING OF MONITORING REPORTS (continued)
[NCGS 143-215.1 (b)]
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.gov/com�)liance/final-national-l-,ollutant-dischar e-elimination-s stem-n des -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:
http://deq.nc.gov/about/divisions/water-resources/edmr
4. Signatory Requirements [Sul}lements Section B. (11.) (b) and Supersedes Section B. (ll.) (d)1
All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section
B. (11.)(a) or by a duly authorized representative of that person as described in Part II, Section B. (I I.)(b). A
person, and not a position, must be delegated signatory authority for eDMR reporting purposes.
For eDMR submissions, the person signing and submitting the DMR must obtain an eDMR user account and
login credentials to access the eDMR system. For more information on North Carolina's eDMR system,
registering for eDMR and obtaining an eDMR user account, please visit the following web page:
