Permit NCO089052
A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and is beginning implementation in late 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)

1. Reporting [Supersedes Section D. (2.) and Section E. (5.) (a)]
Beginning no later than June 1, 2015 (270 days from the effective date of this permit), the permittee
shall begin reporting 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 DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
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.
Requests for temporary waivers from the NPDES electronic reporting requirements 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 using eDMR. Temporary waivers shall be
valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted
electronically to the Division unless the permittee re- applies for and is granted a new temporary
waiver by the Division.

WRC approved of the terms included in the pre -draft and had no additional comments when the
draft permit was sent to public notice. (RS 8/9/2014)

Dear Ms. Deaton,
I am in the process of working on the renewal of the NPDES permit issued for the discharge of treated
wastewater from the Zooland Family Campground WWTP to the Little River in Randolph County.
When the permit was first issued in 2011, its content was strongly influenced by comments you
provided on behalf of the Wildlife Resources Commission. As the time approaches when the permit
renewal is placed at public notice, I wanted to provide you with a pre -draft copy of the permit for your
review. The terms in this draft differ from those in the existing permit. I am hoping that by providing
you with this version now, and soliciting your comments at this time, it may expedite the reissuance of
a final version of the permit.
During the development of the initial permit, the WRC expressed its concerns regarding the potential
effects of the discharge on a diverse population of freshwater mussels inhabiting the river downstream
of the outfall. The WRC's recommendation that chlorine disinfection be replaced with ultraviolet light
was included in a modified design of the WWTP. Additionally, the WRC recommendation that very
low effluent limits for ammonia nitrogen as included in permits for facilities discharging into the
Goose Creek watershed in Mecklenburg and Union Counties was incorporated into the permit.
The limits in the Goose Creek permits were based upon conditions specific to both the discharges and
their receiving streams, and application of those conditions to EPA guidance titled Draft 2009 Update
Aquatic Life Ambient Water Quality Criteria For Ammonia — Freshwater and the Goose Creek Rules
(15A NCAC 2B .0601 —.0609) established by the North Carolina Environmental Management
Commission. In retrospect, it is not certain whether limits developed for facilities discharging into
Goose Creek were appropriate for the conditions associated with the Zooland discharge.
EPA received comments from many respondents to its 2009 draft criteria. Following its review of the
responses, EPA issued revised guidance in 2013 regarding instream ammonia concentrations protective
of freshwater mussels.
As a result of potential misapplication of the 2009 guidance and the updating of the same guidance
from the EPA in 2013, it was thought to be wise to revisit the matter of the effluent limits for the
discharge as established in NPDES permit NC0089052.
In the absence of better data, the USGS determinations of 7Q10 and 30Q2 stream flows at the
discharge location are accepted for development of the renewal permit limits. These flows are:
7Q10 (summer) 0.03cfs
30Q2 (summer) 1.0 cfs
7Q 10 (winter) 0.5 cfs
No water quality data were available for the site, so nearby ambient monitoring were examined. A
sampling location on the Uwharrie River at NC Highway 49 near Farmer, in Randolph County was
selected as being most representative due to its nearby location and stream characteristics at the site. A
sampling summary, taken from a 2012 ambient monitoring report for the Yadkin -Pee Dee River basin,
is attached. The summary indicates the 90`h percentile values for pH and temperature are 7.3 s.u. and
27.1 °C, respectively. Plugging these values into the 2013 EPA guidance (also attached), it suggests a
summer instream ammonia "standard" of 1.0 mg/L.

The 1.0 mg/L value has been entered into a simple model that factors in dilution provided by the
receiving stream to determine potential effluent limits that will be protective of ammonia toxicity. The
model assumes a background ammonia concentration of 0.22 mg/L. In this case, the background value
assumption appears accurate, based upon data from the Uwharrie River site. The result of the model
suggests a chronic (monthly average) limit of 3.5 mg /L during the summer months (April — October).
Using the acute "standard" suggested by the guidance, the model yields an associated summer daily
maximum discharge concentration of ammonia of 28.0 mg /L.
Results of all modeling of winter flow determine that no limits for ammonia are needed due to the
dramatically increased stream flow observed during the winter months.
Based upon the concerns of the WRC, and those of the permittee, who has experienced difficulty in
consistently meeting the existing permit limits, a hybrid scheme is proposed for the establishment of.
limits in the new permit. Ammonia monthly average effluent limit development will remain
conservative, and will take into account the EPA guidance, but will use the 2013 criteria. The 3.5
mg/L value is proposed for the monthly average limit. This value seems protective of instream habitat
and attainable by the existing WWTP. However, it is recommended that other model yields not be
used in order to ensure both protection of downstream uses and to encourage optimization of the
existing treatment facility. A summer daily maximum limit of 17.5 mg /L (derived from application of
standard permitting guidance: 5 x monthly average value) is suggested. Winter limits will be
established at double the summer limits (7.0 mg/L monthly average; 35.0 mg /L daily max).
In addition, due to the higher stream flow during the winter months, BOD winter limits of 10.0 mg/L
(monthly average) and 15.0 mg /L (daily maximum) are proposed. These values are again double those
for summer'limits, consistent with NPDES permitting practices, and remain protective of the dissolved
oxygen standard in winter.
The same reasoning was applied to the limits associated with the 0.017 MGD flow limit. The summer
ammonia limits become tighter with the increased flow (1.9 mg /L monthly average; 9.5 mg /L daily
max). BOD limits and winter ammonia limits would remain the same as found in the 0.006 MGD set
of limits.
Would you please review the attached materials and let me know your thoughts on this matter. Your
comments will be used in preparation of a final version of a draft permit that will be sent to public
notice, and you will be given opportunity to comment on that version as well.
Thank you for your assistance in this matter.

ZERO -FLOW POLICY
The following NPDES permitting policies apply to discharges to zero -flow streams:
• New and Expanding Discharge to Zero Flow Streams ( both 7Q10 and 30Q2 = 0). Regulation 213 .0206
disallows new discharges of oxygen consuming wastewater to streams which have no flow under both 7Q10
and 30Q2 conditions.
• New and Expanding Discharge to Zero Flow Streams (7010= 0: 3002 >0). Regulation 213.0206 sets effluent
limitations at BOD5 = 5 mg/I, NH3 -N= 2 mg/l, and DO = 6 mg/1 to streams with no 7Q10 flow, but positive
30Q2 flow, unless it is determined that these limits will not protect water quality standards.
• Existing Dischargers. Regulation 2B .0206 also states that existing dischargers to zero -flow streams should
be handled on a case -by -case basis. For many years, permits for the existing discharges to so- called "zero -
flow streams" did not contain any special requirements. However, since 1990, three different requirements
have been somewhat randomly placed in NPDES permits. These requirements were:
Require an alternatives analysis be done and give summer limits of 5 mg/L (BODO and 1 mg/I (NH3 -N)
and winter limits of 10 mg/L (BOD5) and 1.8 mg/L (NH3 -N) after a three -year period, if the discharge
continued.
Require an alternatives analysis to meet the above limits, but renew the permit without a change in limits
(i.e., no 3 -year compliance schedule to meet limits) during that permit cycle.
Require an alternatives analysis to meet summer limits of 5 mg/L (BOD5) and 2 mg/L (NH3 -N) and
winter limits of 10 mg/L (BODO and 4 mg/L (NH3 -N) without a change in limits during that permit cycle.
If alternative #1 was implemented in a previous permit, then these limits should be maintained with the exception
of ammonia limits which should be changed to reflect current BAT for facilities with permitted flows of less than
1.0 MGD (2 mg/L and 4 mg/L in the summer and winter, respectively). An alternative analysis is not necessary
for these discharges.
If a facility has never been required to submit an alternatives analysis, then the permit should be renewed with
existing limits and a requirement to perform an alternatives analysis during the next permit cycle. The permit
holder will be required to send in the alternatives analysis six months prior to the expiration date and should be
notified of this requirement in the cover letter to permit issuance.
If a facility has been required to submit an alternatives analysis, but has not done so or has concluded that
discharge is the only option, ammonia limits of 2 mg/L (summer) and 4 mg/L (winter) should be given with a
compliance schedule (when deemed necessary by regional office staff). This schedule should not exceed three
years. In lieu of these ammonia limits, the facility may choose to sample for toxicity using a chronic WET test,
pass /fail at 90% using Ceriodaphnea as the test organism. Existing BOD5 limits should be maintained unless
instream data indicates a potential violation of the dissolved oxygen water quality standard.
If the facility does not discharge into a zero -flow stream, ammonia limitations should be checked against the
Division's Ammonia Toxicity Policy.

RE: Request for NPDES Permit Renewal and Permit Modification
Zooland Family Campground, LLC
Randolph County, NC
NPDES Permit No. NCO089052
Dear Reviewer:
WILLIAM C. DIEHL, P.E.
JOHN F. PHILLIPS, P.E.
ALAN R. KEITH, P.E.
Yom
DEC 2 7 2013
On behalf of the Permiee for the referenced permit, Diehl & Phillips, P.A. is submitting
one original and two copies of a completed NPDES Application — Form D, signed and
dated by the Permiee, and the sludge management plan. It is our understanding that
the cost of the permit renewal is included in the facilities annual fee, and therefore no
payment is enclosed.
We would also like to request your consideration of a modification to the current permit
limits, as a part of the renewal process. To explain our reasons for this request, it is
necessary to briefly review the history of the permit.
The USGS determined in December 2010 that the Little River had the following
estimated flow rates at the proposed point of discharge:
Summer 7Q10 = 0.03 Cubic Feet per Second (CFS)
30Q2 = 1.0 CFS
Winter 7Q10 = 0.50 CFS
A copy of the USGS findings is enclosed (email from Curtis Weaver).
Following submission and approval of an Engineering Alternatives Analysis, DWQ
prepared a draft NPDES permit. The draft NPDES permit was originally issued for review
and in -house comments by the Division of Water Quality in April 2011, and went to
public notice in May of 2011. The effluent limits in the draft permit that are pertinent to
this request were:

NH3 -N Nov. 1 -March 31
4.0 m /I
20.0 m /I
With the S7Q10< 0.05 CFS, the discharge point was classified as having a zero 7Q10;
however, with the 30Q2 flow estimated to be > 0.05 CFS, the Division prepared the
draft permit in accordance with 15A NCAC 213.0206(d)(1).
During the comment period we requested the permit be revised to provide a permit
limits page for an initial monthly average flow limitation of 0.006 MGD, and then a
second permit limits page for the 0.017 MGD flow. This change was requested due to
flow monitoring data that was acquired from water meters that had just been installed
at the campground.
In addition to our comment /request for the phased flow limitations, the Division
received a memorandum from the North Carolina Wildlife Resources Commission, dated
May 23, 2011 (copy enclosed). The memorandum reviewed the list of state and federal
species of concern, endangered, threatened, special concern, and significantly rare
status for which there was a record of them being in the Little River, downstream of the
effluent discharge location.
Their memorandum then expressed concerns regarding the use of chlorination for
disinfection purposes, and regarding the proposed ammonia limits. It noted that the
proposed .017 mgd discharge into a S7Q10 flow of 0.03 CFS created a 46.76% IWC in
the summer. The memorandum then stated that the WRC could concur with the permit
issuance if two changes were made:
1. They requested the proposed chlorination system be replaced by an
ultraviolet light disinfection system, to protect juvenile mussels. The
applicant agreed, and the treatment system was constructed with UV
disinfection.
2. The WRC requested the Ammonia limits "be developed based on EPA's
recommendations in the Draft 2009 Update of Aquatic Life
Ambient Water Quality Criteria for Ammonia — Freshwater. This
document indicates when freshwater mussels are present an acute
criterion of 2.9 mg N/L and a chronic criterion of 0.26 mg N/L (at
pH 8 and 25 °C) be implemented (EPA 2009). Recent NPDES permit
renewals in the Goose Creek watershed have incorporated

(summer /winter) with daily maximum limits of 2.9 mg/11 (summer)

r
The ammonia nitrogen limits that were referenced to an NPDES permit in the Goose
Creek watershed were adopted into the NPDES permit issued for Zooland Campground,
and it is these ammonia - nitrogen limits that we are now requesting be modified in the
renewed permit. Our justifications for this request include the following:
• The document that provided the scientific basis for the WRC request, the
Draft 2009 Update of Aquatic Life Ambient Water Quality Criteria for
Ammonia — Freshwater has been updated and replaced by the Aquatic Life
Ambient Water Quality Criteria for Ammonia — Freshwater 2013 (EPA
Publication 822 -R -13 -001). This document presents the findings of
additional research and analysis, and EPA's revised recommendations
regarding acute and chronic criteria.
• The monthly ammonia - nitrogen limits suggested by the WRC, 0.50 mg /I for
both winter and summer, did not recognize the substantial difference in
Little River's summer and winter 7Q10 flows.
• The acute and chronic criteria cited by the WRC vary with both temperature
and pH, according to both the Draft 2009 report and the Final 2013 report.
The specific concentrations cited by WRC are applicable in waters with a
temperature of 25 °C and a pH of 8.0, but are not the recommended criteria
for lesser temperatures and pH values.
The Aquatic Life Ambient Water Quality Criteria for Ammonia — Freshwater 2013 has
255 pages; rather than enclosing a copy we are providing the link below.

UATIC - LIFE -AM BIENT- WATER - QUALITY- CRITERIA- FOR - AMMONIA- FRESHWATER-
2013.pdf
On page 46 of this document is "Table 6 Temperature and pH- Dependent Values
of the CCC (Chronic Criterion Magnitude) ". This table indicates the chronic
criterion value of 0.56 mg N/L at a pH of 8.0 and a temperature of 25 °C. The
corresponding table in the 2009 Draft document indicated the chronic criterion of 0.26
mg N /L, as cited by the WRC (page 44 of the 2009 document, table titled Temperature
and pH- Dependent Values of the CCC (Chronic Criterion): Mussels Present). Copies of
both tables are included in the Appendix. The link to the 2009 draft document is:

9 12 23 criteria ammonia 2009update.pdf
As stated previously, the CCC increases as pH and /or temperature decrease. While the
receiving stream does reach peak summer temperatures of 250 or 26 °C, it would not
reach a pH of 8.0, based on a review of USGS water quality data for streams in the
same area of the State. USGS Water Quality data for Goose Creek in Union County for
Page 3 of 5

December 1999 to August 2006 indicates a maximum monthly mean temperature of
24.7 and a maximum summer monthly mean pH value of 7.3. Corresponding data for
the Rocky River in Chatham County (February 2009 to present) indicates a maximum
monthly mean temperature of 27.2 and a maximum summer monthly mean pH value of
7.05 (copies of the USGS stream flow data are enclosed). Even if the pH reached a high
of 7.5 with a stream temperature of 26 °C, the corresponding CCC for those conditions
would be 0.95 mg N /L. As pointed out in the WRC memorandum, the IWC% is 46.76 %.
Therefore, if the summer ammonia - nitrogen permit limit was modified to 2.0 mg /l, the
resulting in- stream concentration would be 0.94 mg N /L, which would be compliant with
EPA's 2013 criterion for a pH of up to 7.5 and temperature of 26 °C. If the winter
ammonia - nitrogen limits were revised to 4.0 mg /I as originally proposed by DWQ, the
2013 CCC would not be exceeded. With the winter 7Q10 stream flow of 0.50 CFS, the
IWC% is 5.00 %. With a 4.0 mg /I ammonia nitrogen concentration in the effluent, the
in- stream concentration would be 0.20 mg N /L. This would be within the EPA
recommendations for a (winter) stream temperature of up to 21 °C and a pH of up to
8.8, neither of which is likely to occur.
On page 44 of the 2013 EPA publication is a table titled "Table 5a. Temperature and
pH- Dependent Values of the CMC (Acute Criterion Magnitude) —
Oncorhynchus spp. Present ". This table indicates an acute criterion of 2.6 mg N/L at
pH of 8.0 and a temperature of 25 °C. The counterpart to this table in the 2009 Draft is
on page 42 of that document, and is titled "Temperature and pH- Dependent
Values of the CMC (Acute Criterion Magnitude) — Mussels Present ". It is from
this table that the WRC memorandum found the acute criterion of 2.9 mg N/L for the
8.0 pH and 25 °C conditions. If the NPDES permit Daily Maximum effluent limitation for
ammonia nitrogen was modified to 10 mg /I as originally proposed, the resulting in-
stream concentration in the summer would be 4.67 mg N /L. Using the 2013
recommendations by EPA, this permit limit would produce in- stream concentrations
compliant with the EPA recommendations for temperatures of up to 26 °C with a pH
value of up to 7.6. Similarly, the original NPDES permit limit proposed by DWQ for the
winter Daily Maximum concentration, 20 mg /L of ammonia - nitrogen, would produce in-
stream concentrations compliant with Table 5.a in the 2013 EPA document. The winter
in- stream concentration would be 1.0 mg /L, which would be compliant for winter
stream conditions of up to 21 °C and a pH value of up to 8.6. (The CMC tables from
both 2009 Draft and the 2013 final document are included in the Appendix).
In summary, we request the ammonia - nitrogen limits in the subject NPDES permit be
revised to the limits originally proposed by DWR (then DWQ), prior to the revision
requested by the NC Wildlife Resources Commission's memorandum, as presented
below:
REQUESTED NPDES PERMIT MODIFICATIONS

2.0 m /I
10.0 m /I

20.0 m /I
Page 4 of 5

This request is in keeping with the goals and intentions of the WRC and DWQ. The
decisions made in 2011 were based on the best information and recommendations
available from EPA at that time. Now that EPA has done further research and analysis,
they have replaced the 2009 draft document with the 2013 final document. The
requested modification is basically updating the permit to reflect the new
recommendations, and to also utilize the in- stream waste concentrations to
appropriately calculate the permit effluent limitations. The aquatic life would continue to
be protected with these revised limits, based on EPA's research and data.
This request is also being made because the subject wastewater treatment facility has
struggled to achieve consistent compliance. The relatively small average wastewater
flows have been found to vary widely and rapidly, in both quantity and organic
concentrations. The operators have moved substantially closer to consistent compliance
over the last six months, but have not yet achieved it. The requested permit
modifications stand on the merits and reasons cited above; however, if granted it will
also assist the operators in achieving their goal of consistent compliance.
If you would like to discuss this request in more detail, or would like to meet to discuss
it, please do not hesitate to contact me. We appreciate the Division's consideration of
this permit modification request, and will be glad to assist in any way possible.

Diehl & Phillips Consulting Engineers, P A

Cary, North Carolina 27511
Dear Mr Phillips,
In response to your inquiry about the low -flow characteristics for Little River below Secondary Road 1114 near Ulah in
Randolph County (station id 02127567, drainage area 14 74 sqmi), the following information is provided
A check of the low -flow files here at the USGS North Carolina Water Science Center does not indicate a previous
determination of low -flow characteristics for the point of interest identified in your letter dated November 10, 2010 Where
low -flow estimates have been previously determined for nearby locations in the upper Little River basin, 7Q10 low -flow
yields (expressed as flow per square mile drainage area, or cfsm) used for the estimates have been in the range of 0.005
to 0 01 cfsm
No USGS records of discharge are known to exist for your point of interest However, there are records of miscellaneous
measurements at two locations upstream from your point of interest
• Little River near Ulah (station id 02127566, drainage area 14 1 sqmi, upstream at Secondary Road 1114)
• Little River at Secondary Road 1142 near Ulah (station id 02127560, drainage area 5 3 sqmi approximately).
Sufficient records exist at the latter site for re- assessing the low -flow characteristics that may be considered applicable to
your point of interest
Where no or insufficient data is available for a low -flow analysis, a determination of low -flow characteristics is based on
assessment of low -flow yields at nearby locations where such statistics have previously been determined. The low -flow
characteristics that are provided have been computed by correlating the runoff characteristics of a nearby stream in
vicinity of the request site
Please note the flow estimates do not account for the presence of any diversions or regulation, present or future, which
may occur upstream of the request site
Previously published low -flow information for streams in your area of interest...
For streams in Randolph County, the most recently published low -flow information is a statewide report completed in the

early 1990 .'s It is USGS Water - Supply Paper 2403, 'Low -flow characteristics of streams in North Carolina" (Giese and
Mason, 1993) An online version of the report is available through http*/ /pubs er usgs gov /usgspubs /wsp /wsp2403 The
report provides the low -flow characteristics (based on data through 1988) via regional relations and at -site values for sites
with drainage basins between 1 and 400 sgmi and not considered or known to be affected by regulation and /or diversions
If you access the report, please note the online report files are provided in the " DJVU" format and require a particular
Lizardtech plug -in, also available through a link displayed on the page Or you can click an adjacent link that will allow
you to view the report as a group of images without the need for a plug -in
Considering the above information, please be aware of the following The data provided in the above referenced report
are based on periods of record ending in advance of the drought conditions that have occurred since publication of the
report. In some North Carolina basins, the low -flow conditions observed during the recent droughts (1998 -2002, 2007 -09)
have resulted in lower low -flow statistics. No formal statewide investigation has been completed to document the
changes in low -flow statistics since the droughts However, where updated analyses have been completed for selected
stations, the changes in pre- drought versus updated 7Q10 discharges have shown varying percentage changes of
decline
For instance, at a downstream long -term continuous- record gaging station on Little River near Star in Montgomery County
(station id 02128000, drainage area 106 sgmi, records since April 1954), the 7Q10 declined about 65 percent between the
1997 and 2009 climatic years Based on analysis of available period of record through the 2009 climatic year, the 7Q10
and 30Q2 low -flow estimates have yield values of about 0 004 cfsm and 0 10 cfsm, respectively This gage is currently
the only active site in the Little River basin that drains to the Pee Dee River
Note- The climatic year is the standard annual period used for low -flow analyses at continuous- record gaging stations It
runs from April 1 through March 31 and is designated by the year in which the period begins For example, the 2009
climatic year is from April 1, 2009, through March 31, 2010
Several pieces of information to consider...
(1) A drainage area of 14 74 sqmi was determined for your point of interest on Little River below Secondary Road 1114
near Ulah
(2) Streamflow data and, correspondingly, low -flow characteristics that would be based on such data are very limited in
your area of interest In Table 1 of the above referenced report, there are three partial- record sites in vicinity of your point
of interest for which low -flow discharge estimates are provided Expressing these estimates as low -flow yields (again,
flow per square mile of drainage area, or cfsm) provides some indication of the yield ranges that could potentially be
applicable to your point of interest The 7Q10 low -flow yield range is from about 0.003 to 0.02 cfsm (with an average of
about 0 0.1 cfsm) The 30Q2 low -flow yield range is from about 0 08 to about 0 14 cfsm (with an average of about 0 11
cfsm)
(3) There are no regional low -flow relations available the hydrologic area (7) where this basin is located
(4) Mean annual runoff for streams in this area is mapped in the above referenced report as being approximately 1 0
cfsm
(5) The low -flow characteristics at an upstream partial- record site on Little River at Secondary Road 1142 near Ulah
(station id 02127560, drainage area 5 03 approx , 18 miscellaneous measurements during the 1974 -81 period) were re-
assessed in an analysis using the downstream gaging station near Star as an index site The low -flow yields determined
from this assessment are as follows
7Q10 = 0 0019 cfsm
30Q2 = 0.0698 cfsm
winter 7Q10 = 0 0340 cfsm
7Q2 = 0.0340 cfsm
Please note the above yields for the 7Q10 and 30Q2 estimates are lower than the corresponding ranges specified above
in item #2. This is reflective of the updated low -flow characteristics at the downstream gaging station based on record
including the recent drought periods
Putting together the above pieces of information...

Applying the above low -flow yields (in item #5) to a drainage area of 14 74 sgmi results in following low -flow estimates
7Q10 = 0 03 cfs (equivalent to 0 0019 cfsm)
30Q2 = 1 0 cfs (equivalent to 0 0698 cfsm)
winter 7Q10 = 0 50 cfs (equivalent to 0 0340 cfsm)
7Q2 = 0 50 cfs (equivalent to 0 0340 cfsm)
Applying the yield for mean annual runoff (item #4) to the drainage area results in an estimated average discharge of
about 14 to 15 cfs
A charge of $250 00 for accessing and processing information has been assessed to partially offset these costs. An
electronic invoice covering processing costs for these data is attached to this email as a .PDF file. Instructions for
sending your payment are shown on the invoice
This information is considered preliminary and subject to revision pending further analysis as further data were to become
available, and is made available through our cooperative program of water - resources investigations with the North
Carolina Department of Environment and Natural Resources

FROM: Shannon Deaton, Manager ��7✓�'c'n
Habitat Conservation Program
DATE: 23 May 2011
SUBJECT: NPDES Permit Application for Zooland Family Campground Wastewater Treatment
Plant, Diversified Lending Group, Inc., Randolph County, NPDES Permit No.
NCO089052
Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject
document. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as
amended), Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661- 667d), and
North Carolina General Statutes (G.S. 113 -131 et seq.).
Diversified Lending Group, Inc. has applied for an NPDES permit to discharge treated
wastewater into Little River in the Yadkin River basin. There are records for the federal species of
concern and state endangered Carolina creekshell (Villosa vaughaniana), Atlantic pigtoe (Fusconaia
masoni), Savannah lilliput (Toxolasma pullus), brook floater (Alasmidonta varicosa), and green floater
(Lasmigona subviridis); the state threatened creeper (Strophitus undulatus); the state special concern
notched rainbow (Villosa constricta); and state significantly rare Eastern creekshell (Villosa delumbis)
and Uwharrie's region bivalve (Alasmidonta sp.) in Little River downstream of the proposed discharge.
The Significant Natural Heritage Area — Upper Little River (Randolph/Montgomery) Aquatic Habitat — is
located immediately downstream of the proposed discharge.
The campground has an existing septic tank that was not permitted by DENR or the local health
department. Black septic liquid in a ditch was observed flowing into Little River in September 2010. To
address this issue, the applicant proposes to operate a 0.017 mgd Class II facility that uses chlorine for
disinfection. The 7Q10 for this section of Little River is 0.03 cfs and the IWC% for the summer is 46.76.
The draft permit includes a 28 µg /l daily maximum limit for total residual chlorine (TRC), and monthly
ammonia nitrogen limits (NH3 as N) of 2.0 mg /l (summer) and 4.0 mg /l (winter) with corresponding daily
maximum limits of 10.0 mg /1 and 20.0 mg/l.
The Little River supports a very diverse freshwater mussel population downstream of the
proposed discharge. While untreated sewage can negatively impact aquatic resources, we are concerned
the facility as proposed also has the potential to negatively affect the diverse population of freshwater

mussels in Little River. Therefore, we cannot concur with the issuance of this permit for Zooland Family
Campground as proposed. We could concur with issuance of this permit provided the following changes
are made to the facility and the effluent permit limits.
Chlorine systems are replaced by ultraviolet light systems. Chlorine is acutely toxic to aquatic
organisms and can form secondary compounds that are detrimental to aquatic life. Valenti (2006)
concluded the impact of long term exposure to low doses of chlorine may impact juvenile
mussels and reduce the chance of them being recruited to the reproducing population.
2. Ammonia limits should be developed based on EPA's recommendations in the Draft 2009 Update
of Aquatic Life Ambient Water Quality Criteria for Ammonia — Freshwater. This document
indicates when freshwater mussels are present an acute criterion of 2.9 mg N/L and a chronic
criterion of 0.26 mg N/L (at pH 8 and 25 °C) be implemented (EPA 2009). Recent NPDES permit
renewals in the Goose Creek watershed have incorporated monthly ammonia nitrogen limits (NH3
as N) of 0.5 mg/L (summer /winter) with daily maximum limits of 2.9 mg/L (summer) and 7.15
mg/L (winter).
Thank you for the opportunity to comment on the permit application. If we can be of further
assistance, please contact our office at (336) 449 -7625.

Sludge Management Plan
Zooland Family Campground WWTP
NPDES Permit No. NCO089052
The Zooland Family Campground WWTP (permitted for 6,000 gpd monthly average
flow) has an 8,000 gallon septic tank at the head of the treatment plant, which
intercepts the majority of any settleable or floating suspended solids in advance of the
treatment systems. Waste solids produced from the mixed bed biofilm reactor (MBBR)
process are captured by the clarifier. The solids from the clarifier can be wasted to the
8,000 gpd septic tank. Solids escaping the clarifier should be retained by the pressure
filter, and returned to the FE tank in the filter backwash.
The septic solids are periodically removed by Overbey's Septic Tank Service, Inc. of
McLeansville, NC, for final disposal.
