SUMMARY
This renewal application was originally submitted on November 29, 2010. Since then the
Jordan Lake Wastewater Discharge Rule was modified by Session Laws 2011-394 (1-115119) and
2013-395 (SB515). This permit was than revised and re -drafted to include these modifications
and a Total Nitrogen Reduction Schedule outlining the actions the City will take to achieve
annual total nitrogen targets listed in NPDES Permit NC0021474.
The City of Mebane operates a 2.5 MGD wastewater treatment plant. The treatment plant
serves 10,000 persons in the City of Mebane. The facility consists of a bar screen, grit chamber,
aeration basin, three clarifiers, disk cloth media filtration, chlorine contact basin, sulfur dioxide
dechlorination, rotary drum thickener, sludge holding tank and two aerobic digesters. The City
has made operational changes to comply with the Jordan Lake Nutrient Rules and will continue
to closely evaluate whether these operational changes will be sufficient or if additional changes
will be needed to achieve its final allocation load limitations.
The existing permit limits for the Mebane W WTP are:
Flow = 2.5 MGD
BODS = 5 mg/l (summer); 10 mg/l (winter)
NH3 = 2 mg/l (summer); 4 mg/l (winter)
DO= 6 mg/l
TSS = 30 mg/l

Based on this bill, water quality standards for a stream classified as a water supply will not be
applied to the Mebane WWTP and its discharge into Moadams Creek because the conditions (i)
and (ii) in Section 12.1 (above) are not met in this instance.
TOXICITY TESTING:
Existing limit: Chronic limit at 90% (Ceriodaphnia Pass/Fail). Quarterly testing conducted in
January, April, July, and October.
From January 2009 to December 2013, the facility has passed all 20 toxicity tests.
Recommendation: Continuation of Chronic toxicity limit at 909/6, quarterly testing in
January, April, July and October.
COMPLIANCE SUMMARY:
Overall, compliance with limits in the permit has been achieved by the facility during this
permit cycle. 1) There was an exceedance of the mercury limit in June 2009 and a notice of
violation was issued; however, since that violation, there have been no other exceedances of the
mercury limit. 2) There was only one exceedance of the fluoride limit in 2010, however there
have been no other violations since that time. 3) There were some apparent exceedances of the
total residual chlorine limit, however the current EPA approved compliance level for TRC is 50
ug/l and therefore any reported values less than 50 ug/l are considered zero for compliance
purposes. The reported TRC values were not considered to be limit violations. With the
exception of these minor violations, the Mebane WWTP has been in compliance with most
permit limits since the last renewal in 2006.
INSTREAM MONITORING:
Current Parameters: Dissolved Oxygen, Temperature, Fecal Coliform and Conductivity
Recommended Parameters: Dissolved Oxygen, Temperature, Fecal Coliform, Conductivity
Upstream: Upstream 100 feet of discharge
D1: Downstream at NCSR 1940, Moadams Creek
D2: Downstream at Back Creek at NCSR 1936
D3: Downstream at Back Creek at Highway 54
Mebane is a member of the Upper Cape Fear River Basin Association (UCFRBA) and therefore
individual instream monitoring requirements are waived as long as the City is a member.
The memorandum of agreement between the UCFRBA and DWR was renewed May 1, 2010 and
is effective until April 30, 2015. The UCFRBA conducts instream monitoring for its membership
and compiles data for review and evaluation.
A review of data for station B1350000- Moadams Creek at Corrigidor Road upstream of
discharge near Mebane, indicated only elevated iron and fecal coliform values. All other field
parameters, metals and nutrients were below water quality standards. The station downstream
of Mebane's WWTP, B1380000 — Moadams Creek at SR 1940 Gibson Road near Florence Town,
also showed elevated iron and fecal values, with other parameters below water quality
standards.

MONITORING FREQUENCY REDUCTION EVALUATION,
In December 2012 the City of Mebane submitted data requesting monitoring frequency
reductions for total suspended solids and ammonia -nitrogen. Three years of effluent data was
reviewed (2011-2013) for each parameter and a summary on the analysis is attached and titled -
Effluent Analysis Summary. Reduced monitoring frequencies for total suspended solids and
ammonia -nitrogen were granted based on a review demonstrating long-term treatment
performance at levels consistently below effluent limitations (<50%).
SUMMARY OF PROPOSED CHANGES
• Change the permit expiration date to May 31, 2019 to allow five years before permit
renewal.
• An annual discharge load limit of 40,225 pounds per year (lb/yr) for total nitrogen
has been added to the permit in accordance with the Jordan Lake Nutrient
Management Strategy rules. Footnote #10 in Special Condition A.(1.) specifies an
effective date of calendar year 2019 for the total nitrogen limit, consistent with
Session Law 2013-395 (Senate Bill 515).
• Effluent limitations and monitoring for Fluoride and Chloride were removed from
the permit because no reasonable potential to violate surface WQS's for these
parameters was found. The City will continue to monitor these parameters as part of
their Pretreatment Long Term Monitoring Plan.
• Effluent monitoring for Total Copper was removed from the permit because no
reasonable potential to violate surface WQS's for this parameter was found.
• Based on evaluation of submitted data, the weekly average limit for mercury was
removed because the annual averages were less than the WQBEL and the TBEL.
Also, the maximum value did not exceed the TBEL. In accordance with the
implementation of the 2012 Statewide Mercury TMDL, the City is required to
develop and implement a Mercury Minimization Plan and continue to monitor for
mercury as part of its Effluent Pollutant Scans.
• An evaluation of Total Zinc effluent data showed a reasonable potential to violate
WQS. Since the WQS for Total Zinc is an action level standard, monitoring for Total
Zinc was maintained in the permit, at a reduced frequency of quarterly to coincide
with toxicity testing.
• The monitoring frequencies for total suspended solids and ammonia -nitrogen were
reduced from daily to twice per week based on a review demonstrating long-term
treatment performance at levels consistently below effluent limitations (<50%).
• Minor language has been modified in condition A.(7). Chronic Toxicity Permit Limit.
• Please note the following in Special Condition A.(8.) Effluent Pollutant Scan:
1) Language updated to note three scans must be completed during the permit cycle
and 2) mercury must be sampled using EPA Method 1631E.
• In accordance with Federal Regulations 40 CFR Part 122 a toal nitrogen reduction
schedule containing annual milestones outlining the steps the City of Mebane will

Final
Fact Sheet - NPDES Permit
Jordan Lake NPDES Dischargers
PROPOSED PERMIT ACTION
14 NPDES Permits
In November 2009, the Division proposed to modify fourteen (14) NPDES permits for
municipal and domestic treatment facilities in the Jordan Lake watershed of the Cape Fear
River Basin. The purpose of the modifications was to set Total Phosphorus discharge limits in
accordance with the Jordan Lake Nutrient Management Strategy: Wastewater Discharge
Requirements, T15A NCAC 02B .0270.
JORDAN LAKE NUTRIENT MANAGEMENT STRATEGY
The Jordan Lake Nutrient Management Strategy is a comprehensive set of rules and Session
Law that became effective August 11, 2009. The Strategy aims to restore and maintain water
quality, protect the lake's classified uses, and maintain or enhance protections currently
implemented by local governments in existing water supply watersheds. The Strategy calls for
improvements in stormwater management (existing and new development), agricultural
practices, fertilizer application management, riparian buffers protection, and wastewater
treatment.
The Strategy establishes nitrogen and phosphorus allocations for all existing wastewater
dischargers that treat nutrient -bearing wastes. For point sources, it specifies that facilities with a
permitted flow of 0.1 MGD or greater must meet nutrient limits based on these allocations. The
limits for both nitrogen and phosphorus are given as annual mass limits. The phosphorus limits
become effective in CY2010, the nitrogen limits in CY2016.
The figure below shows the watershed and the three subwatersheds. The strategy sets nutrient
reduction targets for each subwatershed.
PROPOSED PERMIT MODIFICATIONS
The proposed permit modifications affect the fourteen dischargers affected by the new rule,
and these are listed below. (The list once included a fifteenth permit, NC0003913 for Glen
Raven Inc., but that has been rescinded since work began on the Strategy and so is not listed.)
The modifications add a new Special Condition to each permit to identify the discharge and
delivered allocations and the Transport Factor for the permitted facility. The permits include
the new annual mass discharge limits for phosphorus, equal to each facility's TP discharge
allocation. The Division intends to add nitrogen limits during the 2011 permit renewals.
The attached table lists all facilities in the Jordan Lake watershed that received nutrient
allocations under the Wastewater Discharge Requirements rule. It shows the allocations,
transport factors, and permitted flow for each facility. It also shows the equivalent
concentrations for the TN and TP allocations, that is, the concentration that the facility must
reach to meet its mass limit at full permitted flow.
Some of the modifications include other, minor changes. For example, conditions were re-
ordered to group the nutrient -related conditions for easier reference.

L aro
cn­...e ;o ,.a,
In response to your email correspondence on Thursday, March 6, 2014, I respectfully
submit the following comments and proposed Total Nitrogen compliance schedule for
inclusion in the above referenced NPDES permit.
Per the Jordan Lake Nutrient Management Strategy, the City of Mebane WWTP is
required to comply with an annual Total Nitrogen (TN) mass loading of 40,225
lbs/year, end of pipe by the year 2019. At the facility's permitted flow of 2.5MGD, this
annual mass loading is equivalent to an annual average effluent concentration of 5.3
mg/L (end of pipe) of total nitrogen.
The City has already implemented nitrogen -reducing operational changes at the plant
and the Mebane WWTP is continually optimizing operations for total nitrogen removal.
This is demonstrated by the fact that the City has consistently met the Total Nitrogen
targets of the Jordan Lake Nutrient Management Strategy since 2009 as outlined in the
table below.
City of Mebane Comments -Draft NPDES Permit No. NCO021474
Page I of

Total Nitrogen Compliance Schedule
In accordance with Federal Regulations at 40 CFR 122, a schedule of compliance
containing annual milestones outlining the steps the City of Mebane will take to comply
with the Jordan Lake Wastewater Discharge Rule (15A NCAC 02B .0270), as modified
by North Carolina Session Laws 2011-394 (HB119) and 2013-395 (SB515) are listed
below.
April 30, 2015:
• Evaluate and report on the need and interest in establishing a compliance trading
association for Jordan Lake.
April 30, 2016:
• Submit a nutrient removal optimization report for the Mebane WWTP
April 30, 2017:
• Submit a nutrient compliance plan for DWR review and approval. The plan
should project and accommodate anticipated loadings through 2027.
April 30, 2018:
• Submit a nutrient removal optimization report for the Mebane WWTP
January 1, 2019:
• Unless an alternate date is specified in DWR's approval of Mebane's Nutrient
Compliance Plan, the Mebane WWTP shall meet the annual average nutrient
loading limit beginning on January 1, 2019.
If you need any additional information please feel free to contact the undersigned.
Thanks for your assistance in the issuance of this permit.

Subject: TN Compliance Schedule with WWTP milestones
Dennis,
I hope to work on the Monitoring Frequency Reduction review on Monday of next week for the WWTP permit.
Once I get that completed we should be able to move quickly on re -public noticing the WWTP permit.
I am concerned that you start working on a TN compliance schedule for inclusion in the permit. I copied part of the City
of Greensboro's schedule below. This is how they started it and then the rest was submission of packages 1,2,3,4 over
the following years and construction, etc.. NPDES needs something for each year and you can either end it with
complying in 2019 or continue the timeline with receipt of an ATC by 12/31/2019.

Subject:
to language forjordan permit
Jackie - Here is the TN language for Mebane. This should take care of the compliance schedule change adopted last
year by the general assembly.
Julie & Ron - This language should also be included in the Graham, Reidsville, OWASA permits (all Julie's), except with
the correct TN numbers. The Burlington and Greensboro permits (Ron's and Julie's, respectively), need similar language
adapted to their'bubble' permit arrangements. Julie already has that language and can share with Ron when the time
comes.
Here is the Mebane language, followed by a list of TN limits for the other dischargers. In the'TN Load' row of the
effluent sheet, replace'Monitor & Report (lb/yr)' with '40,225 Ib/yr *' - where the asterisk is the next footnote number
(8?). Then add this language as footnote 8Q) and adjust the numbering for the remaining footnotes:
* Per the Jordan Lake Wastewater Discharge Rule (15A NCAC 02B .0270) as modified by North Carolina Session Law
2011-394 (HB119), the annual mass Total Nitrogen limit shall be effective beginning with calendar year 2016, unless the
discharger has received by December 31, 2016, an authorization -to -construct permit for construction, installation, or
alteration of the treatment works for purposes of complying with this limit, in which case the limit shall be effective
beginning with calendar year 2018.
Here are the other TN limits. Check to make sure these agree with the 'discharge' allocations listed in the nutrients
special condition of each permit:
Graham 56,315 lb/yr TN
Reidsville 120,674
OWASA 134,375
Tom - Six Jordan permits already went out without this language, three before the bill was passed and signed. Let's
talk about them separately.

The City of Mebane Wastewater Treatment Plant's NPDES Permit No. NC0021474 issued effective
November 1, 2006 and modified effective August 1, 2010 expires May 31, 2011. Please find enclosed
Mebane's permit renewal application package along with two copies.
Below are comments addressing two parts of the renewal application:
Part B.5 of the application requests information to be provided concerning anticipated plant
improvements. Because of the newly implemented Jordan Lake Nutrient Rules, the City of
Mebane is in the preliminary stage of considering improvement needs as well as funding sources.
Thus, the dates listed in the renewal application for implementation are subject to change. Mebane
is currently in compliance with Total Phosphorus allocation and intends to be in compliance with
Total Nitrogen allocation before the compliance date.
Part E of the application requests that the applicant supplies Whole Effluent Toxicity (WET)
testing data. Mebane has performed quarterly WET testing since the November 1, 2006 issuance
of the current permit. All testing has indicated compliance. Also, during the period October 2009
through July 2010, Mebane performed quarterly second species testing which also indicated
compliance. These reports were submitted to the DWQ Science Branch within thirty days of the
end of each month in which testing occurred. As per the directions under Part E as well as a
telephone conversation with Tom Belznick on November 3, 2010, Mebane is not required to
submit results with this application.
In addition, the City of Mebane requests the involvement of our staff during the permitting process prior to
issuance of a draft permit.
If there are questions or comments please contact the undersigned.

City of Mebane WWTP
Sludge Management Plan
November 1, 2010
Equipment
➢ One 100 gpm Parkson Rotary sludge thickener
➢ Two Stranco Polymer feed pumps with separate mixing tanks
➢ Variable frequency control panel to regulate waste flow
➢ Primary aerobic digester — 220,000 gallons
➢ Secondary aerobic digester — 420,000 gallons
Operations
The waste activated sludge is pumped from the return sludge building
to the sludge thickener building. The waste sludge is approximately
0.3-0.7 % solids. This sludge is mixed with polymer for solids
separation before entering the rotary thickener. The sludge proceeds
through the thickener allowing the filtrate to exit and return to the
head of the plant. The thickened sludge of about 3 to 4 % is
discharged to the primary digester.
As the primary sludge digester fills, sludge is transferred to the
secondary digester. When the secondary is within 2 weeks of being
full Mebane's sludge removal contractor mobilizes. This mobilization
involves setting up a portable sludge belt filter press on site.
Mebane's biosolids contractor uses this filter press to dewater sludge
pumped from the primary and secondary digester. After dewatering to
a cake of about 12 to 19% solids the biosoilds are transported to a
composting facility for further treatment to achieve Class A Biosolids.
Mebane is currently using McGill Composting to accomplish the
composting.
McGill Composting then distributes the compost in bulk for
landscaping and soil enhancement applications.
