Footnotes:
1. U: Upstream at NCSR 1540. Di: Downstream at NCSR 1518. D2: Downstream at NCSR 1327.
2. 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.(2.), Calculation of TN Load.
3. The monthly average effluent BOD5 and TSS concentrations shall not exceed 15% of their respective influent value
(85% removal).
4. TRC Total Residual Chlorine compliance is required for chlorine or chlorine derivative used for disinfection. The Division shall
consider all effluent TRC values reported below 50 ug/1 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 ug/1.
5. 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.
6. For a given wastewater sample, TN = TKN + (NO3-N + NO2-N), where TN is Total Nitrogen, TKN is Total Kjeldahl
Nitrogen, and (NO3-N + NO2-N) are nitrate and nitrite nitrogen, respectively.
7. Compliance with this limit shall be determined in accordance with Special Condition A. (3.) of this permit, Annual Limits
for Total Nitrogen.
THERE SHALL BE NO DISCHARGE OF FLOATING SOLIDS OR VISIBLE FOAM IN OTHER THAN TRACE AMOUNTS.
A. (2.) CALCULATION OF TOTAL NITROGEN LOADS
a. The Permittee shall calculate monthly and annual TN Loads as follows:
i. Monthly TN Load (pounds per month) = TN x TMF x 8.34
Where:
TN = the average TN 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 per 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 discharge
monitoring report for that month and shall report each year's annual results (pounds/year) in the
December report for that year.
A. (3.) ANNUAL LIMITS FOR TOTAL NITROGEN
c. Total Nitrogen (IN) allocations and TN Load limits for NPDES dischargers in the Neuse River basin are annual
limits and are applied for the calendar year.
d. 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 Load is less than or equal to said limit, or
ii. the Permittee is a Co-Permittee Member of a compliance association.
e. 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 IN 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.
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.

BACKGROUND
The La Grange WWTP is a 0.750 MGD plant providing treatment for domestic wastewater that serves a
population of 2,800 in the Town of La Grange in Lenior County. There is one minor industrial source,
small component electrical manufacturer, that discharges to the collection system and was deemed not
significant by the Division. The facility includes oxidation ditches, secondary, and tertiary treatment as
well as biological TN/TP removal capability. Dechlorination is used to control the effluent chlorine
residual level. The existing permit for this facility was issued on November 26, 2003 and expired on June
30, 2008.
The Permittee submitted the required renewal and copies, prepared by Wooten Corporation, using EPA
Form 2A on December 18, 2007. Per John Craft Town Manager request, a preliminary review letter was
sent July 2008 to (1) confirm the status of the permit renewal and to (2) indicate any known permit
changes that may be forthcoming.
Historically, this facility had issues with infiltration. A sewer moratorium was issued in July 2004. The
Permittee made major efforts to resolve the issues associated with the sewer moratorium. The Permittee
requested and the Division granted removal of the sewer moratorium in February 2006.
The Permittee is a member of the Lower Neuse River Association. As a member of the Lower Neuse
River Association the Permittee instream monitoring is part of the approved instream program operated
by the association.
This facility discharges to an unnamed tributary approximately 300 yards upstream from Moseley Creek
in sub -basin 03-04-05 of the Neuse River Basin. From the outfall through Moseley Creek is not listed as
impaired. The Neuse River estuary to which receives all the basin flows, however, is on the 303(d) list
for chlorophyll -a. As a result, all of the this portion of the Neuse River Basin is classified as nutrient
Fact Sheet

sensitive waters (NSW) and must adhere to the nutrient limitations and nutrient reductions set out by
basin plans and the Neuse TMDL and Neuse rules.
Permit requirements and DMR Data Review
This permit contains limits for flow, BOD, TSS, ammonia nitrogen, DO, fecal coliform, total
phosphorus (TP), pH, and total residual chlorine (TRC). Total nitrogen (TN) is monitored and is used to
calculate the mandatory monthly/annual TN Load so adherence to the allocated TN Load can be
determined, monthly and annually. Effluent temperature and zinc are monitored, but are not limited.
Data from Discharge Monitoring Reports (DMRs) was reviewed from April 2005 through April 2008.
Monthly average data except for DO which is daily values are summarized in Table 1. Nutrients and
toxicants daily values are summarized in Table 2.

The TN Load for 2006 and 2007 was 5,847 lbs and 4,216.6 lbs respectively. The annual
allocation was 8,447 lbs. An overall TN nutrients reduction of 31% was gained in 2006 and 52%
in 2007.
Compliance violations (April 2005 — April 2008)
1) 3 violations exceeded maximum flow
2) 2 violations exceeded maximum weekly average fecal coliform
3) 1 violation exceeded maximum daily TRC
4) 1 violation exceeded minimum DO
The annual inspection conducted by the Regional Office indicated no outstanding issues.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
There is no change in the Division application of the WLA, effluent guidelines, and water quality
standards.
TSS, pH, % Removal are major secondary treatment parameters and as such all previous monitoring and
compliance limits will continue in this permit. BOD is a major treatment parameter and the original
calculation to establish BOD limits for the stream oxygen demand impact is still valid and as such all
previous monitoring and compliance limits will continue in this permit.
The original IWC calculation to determine ammonia nitrogen and TRC compliance limits is still
applicable. Fecal coliform, DO, ammonia nitrogen, and TRC are major parameters of concern and as
such all previous monitoring and compliance limits will continue in this permit.
Zinc is an action level toxicant and has exceeded action level limits. Facility uses Ammonia Nitrogen
Limit as toxicity control. Zinc monitoring will be increased to Class IV status of 2/Month in this
permit. Temperature is a parameter of concern and will continue to be monitored in this permit.
Fact Sheet
NPDES NC0021644 Renewal

The Permittee elected ammonia nitrogen limits over chronic WET testing in the original permit.
Neuse TMDL
The permit includes nutrient limits consistent with the Nutrient Management Strategy rule (T15A NCAC
2B .0234).
Nitrogen
The Environmental Management Commission adopted Nutrient Management Strategy rules in December
1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The point source rule (T15A
NCAC 2B .0234) sets Total Nitrogen (TN) discharge limits for all point source dischargers larger than
0.5 MGD.
The rule also allows dischargers to form a group compliance association and work together to reduce
nitrogen; this option allows the association members added flexibility in controlling nitrogen discharges.
At the same time, the association is subject to a group NPDES permit ensuring that the association and its
individual members are accountable if they exceed the applicable nitrogen limits.
Under the rule, there are three types of TN limit in the Neuse:
1. the individual limits in the dischargers' individual permits,
2. the aggregate limit in an association's group NPDES permit, and
3. the individual allocations/limits for each Association member, also in that association permit.
A discharger may be subject to the first type of limit, or to the second and third, but never to all three at
the same time. The discharger is first subject to the TN limit (if any) in its individual NPDES permit. If
becomes a co-Permittee to a compliance association's group NPDES permit, it is then governed by the
TN limits in that permit. If the association complies with its group TN limit in a given year, all members
are deemed to be in compliance with their individual allocations/ limits in the group permit. If the
association exceeds its limit, the members then become subject to their individual allocations/ limits as
well.
Regardless of which permit governs a TN discharge, allocations/ limits will likely change over time as
the dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The Division will
modify the affected permits as necessary to ensure that the limits are kept up to date and reflect any such
transactions.
Under the new rule, the Permittee received a TN Load limit of 8,447 lb./yr., a calendar year limit. This
limit will be calculated annually. In addition to this limit, the Permittee will be required to report total
monthly flow, total kjeldahl nitrogen and the sum of nitrate and nitrite in addition to the existing
requirement to report monthly total nitrogen concentrations and loads.
The Town is a member of the Neuse River Compliance Association at this time. So long as it remains a
co-Permittee member, it is deemed to be in compliance with the TN limit in this permit, and its TN
discharge is governed instead by the Association's group NPDES permit, issued December 30, 2002.
During this permit cycle addition narrative in a Special Condition was added to further clarify the
transport factor previously applied in used in the new rules.
Phosphorus: The Permitee's 2.0 mg/L Total Phosphorus limit will be removed but will continue weekly
monitoring in this permit.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• Special Condition narrative to clarify the nutrient transport factor
• Updated TRC language
• TP Limit removed but monitoring remained
• Total Zinc monitoring frequency increased to 2/month

BACKGROUND
The La Grange WWTP is a 0.750 MGD plant providing treatment for domestic wastewater that serves a
population of 2,800 in the Town of La Grange in Lenior County. There is one minor industrial source,
small component electrical manufacturer, that discharges to the collection system and was deemed not
significant by the Division. The facility includes oxidation ditches, secondary, and tertiary treatment as
well as biological removal capability. Dechlorination is used to control the effluent chlorine residual
level. The existing permit for this facility was issued on November 26, 2003 and expired on June 30,
2008.
The Permittee submitted the required renewal and copies, prepared by Wooten Corporation, using EPA
Form 2A on December 18, 2007. Per John Craft Town Manager request, a preliminary review letter was
sent July 2008 to (1) confirm the status of the permit renewal and to (2) indicate any known permit
changes that may be forthcoming.
Historically, this facility had issues with infiltration. A sewer moratorium was issued in July 2004. The
Permittee made major efforts to resolve the issues associated with the sewer moratorium. The Permittee
requested and the Division granted removal of the sewer moratorium in February 2006.
The Permittee is a member of the Lower Neuse River Association. As a member of the Lower Neuse
River Association the Permittee instream monitoring is part of the approved instream program operated
by the association.
This facility discharges to an unnamed tributary approximately 300 yards upstream from Moseley Creek
in sub -basin 03-04-05 of the Neuse River Basin. From the outfall through Moseley Creek is not listed as
impaired. The Neuse River estuary to which receives all the basin flows, however, is on the 303(d) list
for chlorophyll -a. As a result, all of the this portion of the Neuse River Basin is classified as. nutrient

sensitive waters (NSW) and must adhere to the nutrient limitations and nutrient reductions set out by
basin plans and the Neuse TMDL and Neuse rules.
Permit requirements and DMR Data Review
This permit contains limits for flow, BOD, TSS, ammonia nitrogen, DO, fecal coliform, total
phosphorus (TP), pH, and total residual chlorine (TRC). Total nitrogen (TN) is monitored and is used to
calculate the mandatory monthly/annual TN Load so adherence to the allocated TN Load can be
determined, monthly and annually. Effluent temperature and zinc are monitored, but are not limited.
Data from Discharge Monitoring Reports (DMRs) was reviewed from April 2005 through April 2008.
Monthly average data except for DO which is daily values are summarized in Table 1. Nutrients and
toxicants daily values are summarized in Table 2.

The TN Load for 2006 and 2007 was 5,847 lbs and 4,216.6 lbs respectively. The annual
allocation was 8,447 lbs. An overall TN nutrients reduction of 31% was gained in 2006 and 52%
in 2007.
Compliance violations (April 2005 — April 2008)
1) 3 violations exceeded maximum flow
2) 2 violations exceeded maximum weekly average fecal coliform
3) 1 violation exceeded maximum daily TRC
4) 1 violation exceeded minimum DO
The annual inspection conducted by the Regional Office indicated no outstanding issues.
PERMITTING STRATEGY
Waste Load Allocation (WLA)
There is no change in the Division application of the WLA, effluent guidelines, and water quality
standards.
TSS, pH, % Removal are major secondary treatment parameters and as such all previous monitoring and
compliance limits will continue in this permit. BOD is a major treatment parameter and the original
calculation to establish BOD limits for the stream oxygen demand impact is still valid and as such all
previous monitoring and compliance limits will continue in this permit.
The original IWC calculation to determine ammonia nitrogen and TRC compliance limits is still
applicable. Fecal coliform, DO, ammonia nitrogen, and TRC are major parameters of concern and as
such all previous monitoring and compliance limits will continue in this permit.
Zinc is an action level toxicant and as such its monitoring will continue in this permit. Temperature is a
parameter of concern and will continue to be monitored in this permit.
The Permittee elected ammonia nitrogen limits over chronic WET testing in the original permit.

Neuse TMDL
The permit includes nutrient limits consistent with the Nutrient Management Strategy rule (T15A NCAC
2B .0234).
Nitrogen
The Environmental Management Commission adopted Nutrient Management Strategy rules in December
1997, classifying the entire Neuse River Basin as Nutrient Sensitive Waters. The point source rule (T15A
NCAC 2B .0234) sets Total Nitrogen (TN) discharge limits for all point source dischargers larger than
0.5 MGD.
The rule also allows dischargers to form a group compliance association and work together to reduce
nitrogen; this option allows the association members added flexibility in controlling nitrogen discharges.
At the same time, the association is subject to a group NPDES permit ensuring that the association and its
individual members are accountable if they exceed the applicable nitrogen limits.
Under the rule, there are three types of TN limit in the Neuse:
1. the individual limits in the dischargers' individual permits,
2. the aggregate limit in an association's group NPDES permit, and
3. the individual allocations/limits for each Association member, also in that association permit.
A discharger may be subject to the first type of limit, or to the second and third, but never to all three at
the same time. The discharger is first subject to the TN limit (if any) in its individual NPDES permit. If
becomes a co-Permittee to a compliance association's group NPDES permit, it is then governed by the
TN limits in that permit. If the association complies with its group TN limit in a given year, all members
are deemed to be in compliance with their individual allocations/ limits in the group permit. If the
association exceeds its limit, the members then become subject to their individual allocations/ limits as
well.
Regardless of which permit governs a TN discharge, allocations/ limits will likely change over time as
the dischargers purchase, sell, trade, lease, or otherwise transfer nitrogen allocations. The Division will
modify the affected permits as necessary to ensure that the limits are kept up to date and reflect any such
transactions.
Under the new rule, the Permittee received a TN Load limit of 8,447 lb./yr., a calendar year limit. This
limit will be calculated annually. In addition to this limit, the Permittee will be required to report total
monthly flow, total kjeldahl nitrogen and the sum of nitrate and nitrite in addition to the existing
requirement to report monthly total nitrogen concentrations and loads.
The Town is a member of the Neuse River Compliance Association at this time. So long as it remains a
co-Permittee member, it is deemed to be in compliance with the TN limit in this permit, and its TN
discharge is governed instead by the Association's group NPDES permit, issued December 30, 2002.
During this permit cycle addition narrative in a Special Condition was added to further clarify the
transport factor previously applied in used in the new rules.
Phosphorus: The Permitee's 2.0 mg/L Total Phosphorus limit is carried forward in the new permit.
SUMMARY OF PROPOSED CHANGES
In keeping with Division policies, the following will be incorporated into the permit:
• Special Condition narrative to clarify the nutrient transport factor
• Updated TRC language

Dear Mrs. Sprinkle:
DEC 2 7 2007
DENR • ViATER QUALI T _..
R�If.'7 SOURCE SRANC:i
Attached is the information necessary for the Town of La Grange to request
renewal of NPDES Permit No. NC0021644. The following attachments include
the NPDES Form 2A, a topographic map of the area, a process flow diagram, and
a sludge management plan.
Attached in the appendix are letters from the NCDENR NPDES Unit and
NCDWQ Pretreatment Unit. The letter from the NPDES Unit dated October 31,
2002 states that the Town is not required to submit effluent data for toxicity, oil
and grease, or total dissolved solids with the permit renewal application until the
Unit deemed the information necessary. The letter from the NCDWQ
Pretreatment Unit dated March 2, 2004 confirms that the Town of La Grange has
one industrial user and that user is not categorical and discharges less than 25,000
gpd.
It should be noted that the effluent data showed one permit violation for Total
Residual Chlorine on October 5, 2007. The measured value was 30 µg/L and the
daily maximum limit is 17 µg/L. This is a single occurrence in 356 monitoring
events.
If you have any questions please contact John Craft, Town Manager at (252) 566-
3186, or our office at [phone].
