A. (2.) ELECTRONIC REPORTING - 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 will begin implementing in 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.) Signatory Requirements

Beginning no later than 270 days from the effective date of this permit, 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

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.

Permit NCO089478
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.
Information on eDMR and application for a temporary waiver from the NPDES electronic reporting
requirements is found on the following web page:
http://portal.ncdeiir.org/web/wq/admin/bog/ipu/edmr
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

MEMORANDUM
TO: Joe Corporon NC9
FROM: Teresa Rodriguez
DATE: 3/ 6/ 2014
SUBJECT: Level B Model Results Camp Watia WWTP
I performed a level B analysis for the proposed discharge of 0.012 MGD from Camp Watia
WWTP into Townhouse Branch near Bryson City in Swain County. This memo summarizes
the level B model.
Flow Statistics for Townhouse Branch were provided by the USGS as follows:
S7Q10 = 0.29 cfs
W7Q10 = 0.33 cfs
30Q2 = 0.50 cfs
Q average =1.9 cfs
Model Setup:
The proposed location of the discharge is approximately 0.7 miles from the confluence with
the Nantahala River at latitude 35' 20' 11" and longitude 83' 35' 42".
Only one segment was modeled, from the discharge point to the Nantahala River. The length
of the segment was 0.7 miles. The calculated slope was 741 ft/mi.
Wastewater was assumed to be treated to secondary standards (BOD = 30 mg/1). The
allowable ammonia concentration is 13 mg/1 as calculated based on dilution.
The model was run only for the summer season as the discharge will only take place June
thru August.
Model Results:
The level B model predicted a minimum dissolved oxygen (DO) concentration of 7.25 mg/1
and an end DO of 8.44 mg/1. DO in the stream will be protected with limits of 30 mg/1 for
BOD and 13 mg/l for ammonia.

Introduction:
The YMCA of Western North Carolina is expecting to develop a summer youth camp
on a large tract of land located in Swain County, North Carolina (Map "A & B"). This
camp will be developed over a 10 year period with construction expected to start in the
summer of 2014. A copy of the site Master Development Plan is attached to this report
(Map "C").
The water supply for this camp will be from a new community (public) water system
approved by the State of North Carolina. Well(s) have been drilled in 2012 with a
substantial safe groundwater supply yield to allow the development of the summer camp
as proposed.
The wastewater generated from this development will be collected and treated prior to
discharge into Townhouse Branch which is a tributary to the Nantahala River.

Wastewater Discharge:
The proposed treated wastewater will be discharged to Townhouse Branch which is a
tributary to the Nantahala River arm of Fontana Lake in the Little River Tennessee River
Basin. This surface water stream is identified as Index 2-58 with a classification "C"
from the NCDENR. A map of the proposed discharge point and drainage basin is
attached to this report as Map"D".

Stream Capacity:
The applicant submitted a formal request to the USGS in Raleigh for a stream capacity
determination. A copy.of their report (Exhibit # 1) indicates that the annual 30Q2 yield is
0.50 cfs and the annual 7Q10 yield is 0.29 cfs.
The upstream drainage area is approximately 0.75 sq miles (480 acres) of undeveloped
forest land (see Map "D").
Local Government Review:
The proposed camp site is located entirely within the boundary of Swain County,
North Carolina. A copy of the proposed Cainp Watia Site Development Master Plan has
been submitted to the Swain County government for review. Attached is a copy of the
Local Government Review Form (Exhibit # 2) which acknowledges their jurisdiction
over the proposed project.

This assumes that all campers and staff will discharge 60 gpd per person to the
treatment facility
Wastewater Treatment Alternatives:
The applicant understands that it is the goal of North Carolina to minimize or
eliminate point source discharges to surface waters. The following wastewater disposal
alternatives have been investigated and evaluated for this project:
Alternative A - Existing Wastewater Treatment Facilities:
The existing wastewater discharge facilities located within 5 miles of the proposed
discharge point have been identified from State records. There is only one(1) facility
with this area (see Map" D").
The facility is the Nantahala Outdoor Center WWTP located on the Nantahala River.
It is approximately 1 mile from the project site. This facility has an existing facility
designed to treat 40,000 GPD. The facility operates under NPDES
Permit # NC 0057193.
The applicant has reviewed the proposed project with the owner of the Nantahala
Outdoor Center for the past 12 months. The negotiations for purchase of some of the
reserve treatment capacity of this facility have not been successful. The owner wishes to
reserve its capacity for future development of their property.
Alternative B — Land Application
The proposed camp site is located in very steep topography typical of Swain County.
The steep slopes, natural streams and wetland areas all limit the land available for any
type of land application disposal system. The attached map shows these features in the
area near the proposed camp site. It appears that there may be four (4) areas that could
potentially serve as land application areas.
An investigation of the existing soil types and characteristics have been made using
the USDA National Cooperative Soil Survey website. A report on each of the sites for
land application by irrigation (site"A") or rapid infiltration from a drain field (site"B")
was downloaded and printed in attached Exhibit # 3. It is clear from these reports that the
soil types in all four (4) of the areas is unsuitable for either type of land application.
The anticipated flow at full development has been stated to be 12,000 gpd. Based
upon even the best soil loading rate for these conditions of 0.2 gpd / SF it appears that a
total land area of approximately 6.1 acres would be needed for a standard drain field.
The largest single area available for a drain field is site 1 (2.75 acres) and the total area of,
all four (4) sites is 5.25 acres. It is clear that even if all of these sites could be permitted
the area is far below that required to develop either type of land application.

There is an option to the standard drainfield system — drip irrigation. This would be
more feasible in these mountain conditions with variable soils. This option is used in the
detailed cost analysis.
Alternative C — Wastewater Reuse
The alternative reuse of the treated wastewater for bathroom toilets will require a split
system. All of the wastewater will be treated with a standard septic system.. The effluent .
will be collected and a portion will be directed to the restroom facilities and the balance
will be directed to a drip irrigation system.
Alternative D — Direct Discharge
The applicant has requested that a direct discharge of 12,000 GPD be authorized for
this proposed facility. The estimated stream flow data from USGS — Raleigh are positive
which should be enough to allow for the proposed discharge. A report of the anticipated
stream flow is attached as Exhibit "1".
Also attached is a map (" D") which shows the proposed WWTP discharge point and a
layout of the proposed wastewater, treatment facility (Map "F").
The applicant has entered into an agreement with the current landowner to allow for
the development of the Camp Watia and this proposed wastewater treatment facility. The
applicant understands that the facility must provide a standby power source to assure
operational reliability.

The steep slopes, natural streams and. wetland areas all limit -the land available for any
,. p
__. type of land application :disposal system. The .attached map shows these features in. the
area near the proposed camp. site. It appears that here may be four (4) areas that could .
potentially serve as land application areas.
An investigation of the existing soil types and characteristics have been made using
the USDA National -Cooperative Soil Survey webs'ite. A report on each of the sites for
land application by irrigation (site"A") or rapid infiltration from a drain -field (site"B")
was downloaded and printed in attached Exhibit. # 3. It is,clear from these reports that the
soil types in all four (4) of the areas is unsuitable. for either type of land application.
The anticipated flow at full development has been stated to be 12,000 gpd. Based
upon even,the best soil loading rate for these conditions of 0.2 gpd / SF it appears that a.
total land area of approximately 6.1 acres would be needed for a standard drain field.
The largest single area available for a drain field is site 1 (2.75 acres) and the total area of
all four (4) sites is 5.25 acres. It is clear that even if all of these sites could be permitted
the area is far below that required to develop either type of land application.

Alternative cC - Wastewater Reuse
The alternative reuse of the treated wastewater for irrigation has been discussed under
Alternative B.: The estimated quantity of :wastewater from .toilet :flushing -at full
development of the camp is 1 530 d 153 10 d . This amount is relativel
gl? ( @ gP.) _ Y
insignificant compared- to the: total amount to be treated (I2;000 GPD). It is not feasible
to treat all of the -wastewater and reuse only � a small portion - while - discharging -the
balance..
Alternative D — Direct Discharge
The applicant has requested that a direct discharge of 12;000 GPD be authorized for
this proposed: facility. . The estimated stream flow data from USGS — Raleigh :are positive
which should be- enough to allow for the proposed discharge. A report of the anticipated
stream flow is attached as Exhibit 1 ".
Also. attached is a map: (" D") which shows the proposed WWTP discharge point.and a
layout.of the proposed wastewater treatment facility (Map "F").
The applicant has enterednto an agreement .with the current landowner to allow for
the development of the Camp Watia'and this, proposed -wastewater treatment facility. The
applicant understands. that the facility.must provide: a standby power- source.to-
operational reliability.

Date: January 08, 2014
Mr. William G. Lapsley, PE
William G. Lapsley & Associates,PA
214 North King Street
Hendersonville, North Carolina 28792
Mr. Lapsley,
In response to your request (via email dated December 19, 2013) for a formal determination of the low -flow characteristics
on Townhouse Branch at Wesser in Swain County, 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 low -flow determination for your specific point
of interest on Townhouse Branch as shown on the map attached to your email
dated December 17, 2013. No USGS discharge records are likewise known to
exist for your point of interest.
In the absence of site -specific discharge records sufficient for a low -flow analysis,
estimates of low -flow characteristics at ungaged locations are determined by
assessing a range in the low -flow yields (expressed as flow per square mile
drainage area, of cfsm) at nearby sites where such estimates have previously
been determined.
A drainage -area delineation completed using the online NC StreamStats
application (http://water.usgs.gov/osw/streamstats/north carolina.html) indicates
the drainage area for your point of interest is 0.75 sgmi.
Previously published low -flow information for streams in your area of interest
For streams in Swain 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 at
http://pubs.usgs.gov/wsp/2403/report.pdf. 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.
Please note the low -flow characteristics in the statewide report are based on data
ending during the late 1980's and do not reflect the occurrence of recent

droughts, which have resulted in decreased low -flow statistics at some USGS
streamgaging stations across North Carolina.
Sta. 03506010 Townhouse Branch at Wesser, NC
Location: Approximately 0.7 miles upstream from mouth, and approximately 0.8 mile north-northwest of Wesser
Lat/long ==> 035d 20m 40.37s // 083d 35m 43.44s (referenced to NAD83)
County: Swain County
Drainage area = 0.75 sqmi
HUC: 06010202
Map: Wesser [F-4-SE]
Tributary to: Nantahala River
Based on seven (7) nearby selected USGS partial -record sites in general vicinity
of Townhouse Branch, a range of potential low -flow yields were assessed for the
7Q10, 30Q2, winter 7Q10 (W7Q10), and 7Q2 low -flow discharges. The average
for each yield range was determined, and when applied to the drainage area for
your point of interest (0.75 sgmi), the estimated flows based on these yields were
determined. The range and average low -flow yields along with corresponding
estimated flows are provided in the table below.

The mean annual runoff (Plate 2, Giese and Mason, 1993) determined for streams in vicinity of the Townhouse Branch
basin is estimated to be 2.5 cfsm, resulting in an average annual discharge estimated at approximately 1.9 cfs.
Please note the estimated flow estimates reflect "natural -flow" characteristics with no diversions or regulation known to
occur upstream of the request site.
Notes:
(1) As noted above, please be aware the low -flow characteristics in the above -referenced report are
based on data ending during the late 1980's that do not reflect the occurrence of recent droughts,
which have resulted in decreased low -flow statistics at some USGS streamgaging stations.
The USGS North Carolina Water Science Center is currently conducting an update
of low -flow statistics at continuous -record streamgages to account for the recent droughts where
records are available. At a nearby USGS continuous -record streamgage on Nantahala River
near Rainbow Springs in Macon County (station id 03504000, drainage area 51.9 sgmi),
the 7Q10 discharge decreased about 6 percent between the 1998 and 2011 climatic years.
(2) The climatic year is the standard annual period used for low -flow analyses at continuous -record streamgages and runs
from April 1 through March 31, designated by the year in which the period begins. For example, the 2011 climatic year is
from April 1, 2011, through March 31, 2012.
(3) Estimated flows are provided in units of cubic feet per second (cfs).
(4) The information provided in this message is based on a preliminary assessment and considered provisional, subject to
revision pending further analyses.
Invoice information:

A charge of $250.00 for accessing and processing information has been assessed to partially offset these costs.
An invoice covering the processing costs for these data will be sent via regular mail from the U.S. Geological Survey to
the billing address shown below. Instructions for sending your payment will be shown on the invoice.

RE: Camp Watia
YMCA of Western North Carolina
Dear Mr. King:
The YMCA of Western North Carolina is in the final planning stage of the
development of a summer camp for young people to be located on a large tract of land on
Watia Creek Road. Attached is a plan showing the camp layout and proposed site
improvements.
In conjunction with the development of this camp it will be necessary to construct a
central wastewater collection and treatment system. The wastewater will be treated in
accordance with Federal/State regulations and system design standards. The first step in
this process is to obtain an NPDES Discharge Permit.
Enclosed please find a Local Government Review Form which we must submit along
with our application for the permit. Please fill in the appropriate information, sign and
notarize the form and return it to our office at your earliest convenience. If you have any -
questions or need additional information please feel free to contact: our office.

Disposal of Wastewater by Irrigation —Swain County Area, North Carolina
Description
Wastewater includes municipal and food -processing wastewater and effluent from
lagoons or storage ponds. Municipal wastewater is the waste stream from a
municipality. It contains domestic waste and may contain industrial waste. It may
have received primary or secondary treatment. It is rarely untreated sewage. Food -
processing wastewater results from the preparation of fruits, vegetables, milk,
cheese, and meats for public consumption. In places it is high in content of sodium
and chloride. The effluent in lagoons and storage ponds is from facilities used to
treat or store food -processing wastewater or domestic or animal waste. Domestic
and food -processing wastewater is very dilute, and the effluent from the facilities
that treat or store it commonly is very low in content of carbonaceous and
nitrogenous material; the content of nitrogen commonly ranges from 10 to 30
milligrams per liter. The wastewater from animal waste treatment lagoons or
storage ponds, however, has much higher concentrations of these materials,
mainly because the manure has not been diluted as much as the domestic waste.
The content of nitrogen in this wastewater generally ranges from 50 to 2,000
milligrams per liter. When wastewater is applied, checks should be made to ensure
that nitrogen, heavy metals, and salts are not added in excessive amounts.
Disposal of wastewater by irrigation not only disposes of municipal wastewater and
wastewater from food -processing plants, lagoons, and storage ponds but also can
improve crop production by increasing the amount of water available to crops. The
ratings are based on the soil properties that affect the design, construction,
management, and performance of the irrigation system. The properties that affect
design and management include the sodium adsorption ratio, depth to a water
table, ponding, available water capacity, saturated hydraulic conductivity (Ksat),
slope, and flooding. The properties that affect construction include stones, cobbles,
depth to bedrock or a cemented pan, depth to a water table, and ponding. The
properties that affect performance include depth to bedrock or a cemented pan,
bulk density, the sodium adsorption ratio, salinity, reaction, and the cation -
exchange capacity, which is used to estimate the capacity of a soil to adsorb heavy
metals. Permanently frozen soils are not suitable for disposal of wastewater by
irrigation.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations

between the point at which a soil feature has the greatest negative impact on the
use (1.00) and the point at which the soil feature is not a limitation (0.00).
The map unit components listed for each map unit in the accompanying Summary
by Map Unit table in Web Soil Survey or the Aggregation Report in Soil Data Viewer
are determined by the aggregation method chosen. An aggregated rating class is
shown for each map unit. The components listed for each map unit are only those
that have the same rating class as listed for the map unit. The percent composition
of each component in a particular map unit is presented to help the user better
understand the percentage of each map unit that has the rating presented.
Other components with different ratings may be present in each map unit. The
ratings for all components, regardless of the map unit aggregated rating, can be
viewed by generating the equivalent report from the Soil Reports tab in Web Soil
Survey or from the Soil Data Mart site. Onsite investigation may be needed to
validate these interpretations and to confirm the identity of the soil on a given site.

• Disposal of Wastewater by Rapid Infiltration —Swain County Area, North Carolina
Description
Rapid infiltration of wastewater is a process in which wastewater applied in a level
basin at a rate of 4 to 120 inches per week percolates through the soil. The
wastewater may eventually reach the ground water. The application rate commonly
exceeds the rate needed for irrigation of cropland. Vegetation is not a necessary
part of the treatment; thus, the basins may or may not be vegetated. The thickness
of the soil material needed for proper treatment of the wastewater is more than 72
inches. As a result, geologic and hydrologic investigation is needed to ensure
proper design and performance and to determine the risk of ground -water pollution.
Soil properties are important considerations in areas where soils are used as sites
for the treatment and disposal of organic waste and wastewater. Selection of soils
with properties that favor waste management can help to prevent environmental
damage.
Municipal wastewater is the waste stream from a municipality. It contains domestic
waste and may contain industrial waste. It may have received primary or secondary
treatment. It is rarely untreated sewage. Food -processing wastewater results from
the preparation of fruits, vegetables, milk, cheese, and meats for public
consumption. In places it is high in content of sodium and chloride. The effluent in
lagoons and storage ponds is from facilities used to treat or store food -processing
wastewater or domestic or animal waste. Domestic and food -processing
wastewater is very dilute, and the effluent from the facilities that treat or store it
commonly is very low in content of carbonaceous and nitrogenous material; the
content of nitrogen commonly ranges from 10 to 30 milligrams per liter. The
wastewater from animal waste treatment lagoons or storage ponds, however, has
much higher concentrations of these materials, mainly because the manure has
not been diluted as much as the domestic waste. The content of nitrogen in this
wastewater generally ranges from 50 to 2,000 milligrams per liter. When
wastewater is applied, checks should be made to ensure that nitrogen, heavy
metals, and salts are not added in excessive amounts.
The ratings are based on the soil properties that affect the risk of pollution and the
design, construction, and performance of the system. Depth to a water table,
ponding, flooding, and depth to bedrock or a cemented pan affect the risk of
pollution and the design and construction of the system. Slope, stones, and cobbles
also affect design and construction. Saturated hydraulic conductivity (Ksat) and
reaction affect performance. Permanently frozen soils are unsuitable for waste
treatment.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or

expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations

Disposal of Wastewater by Irrigation —Swain County Area, North Carolina
Description
Wastewater includes municipal and food -processing wastewater and effluent from
lagoons or storage ponds. Municipal wastewater is the waste stream from a
municipality. It contains domestic waste and may contain industrial waste. It may
have received primary or secondary treatment. It is rarely untreated sewage. Food -
processing wastewater results from the preparation of fruits, vegetables, milk,
cheese, and meats for public consumption. In places it is high in content of sodium
and chloride. The effluent in lagoons and storage ponds is from facilities used to
treat or store food -processing wastewater or domestic or animal waste. Domestic
and food -processing wastewater is very dilute, and the effluent from the facilities
that treat or store it commonly is very low in content of carbonaceous and
nitrogenous material; the content of nitrogen commonly ranges from 10 to 30
milligrams per liter. The wastewater from animal waste treatment lagoons or
storage ponds, however, has much higher concentrations of these materials,
mainly because the manure has not been diluted as much as the domestic waste.
The content of nitrogen in this wastewater generally ranges from 50 to 2,000
milligrams per liter. When wastewater is applied, checks should be made to ensure
that nitrogen, heavy metals, and salts are not added in excessive amounts.
Disposal of wastewater by irrigation not only disposes of municipal wastewater and
wastewater from food -processing plants, lagoons, and storage ponds but also can
improve crop production by increasing the amount of water available to crops. The
ratings are based on the soil properties that affect the design, construction,
management, and performance of the irrigation system. The properties that affect
design and management include the sodium adsorption ratio, depth to a water
table, ponding, available water capacity, saturated hydraulic conductivity (Ksat),
slope, and flooding. The properties that affect construction include stones, cobbles,
depth to bedrock or a cemented pan, depth to a water table, and ponding. The
properties that affect performance include depth to bedrock or a cemented pan,
bulk density, the sodium adsorption ratio, salinity, reaction, and the cation -
exchange capacity, which is used to estimate the capacity of a soil to adsorb heavy
metals. Permanently frozen soils are not suitable for disposal of wastewater by
irrigation.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations

Disposal of Wastewater by Rapid Infiltration —Swain County Area, North Carolina
Description
Rapid infiltration of wastewater is a process in which wastewater applied in a level
basin at a rate of 4 to 120 inches per week percolates through the soil. The
wastewater may eventually reach the ground water. The application rate commonly
exceeds the rate needed for irrigation of cropland. Vegetation is not a necessary
part of the treatment; thus, the basins may or may not be vegetated. The thickness
of the soil material needed for proper treatment of the wastewater is more than 72
inches. As a result, geologic and hydrologic investigation is needed to ensure
proper design and performance and to determine the risk of ground -water pollution.
Soil properties are important considerations in areas where soils are used as sites
for the treatment and disposal of organic waste and wastewater. Selection of soils
with properties that favor waste management can help to prevent environmental
damage.
Municipal wastewater is the waste stream from a municipality. It contains domestic
waste and may contain industrial waste. It may have received primary or secondary
treatment. It is rarely untreated sewage. Food -processing wastewater results from
the preparation of fruits, vegetables, milk, cheese, and meats for public
consumption. In places it is high in content of sodium and chloride. The effluent in
lagoons and storage ponds is from facilities used to treat or store food -processing
wastewater or domestic or animal waste. Domestic and food -processing
wastewater is very dilute, and the effluent from the facilities that treat or store it
commonly is very low in content of carbonaceous and nitrogenous material; the
content of nitrogen commonly ranges from 10 to 30 milligrams per liter. The
wastewater from animal waste treatment lagoons or storage ponds, however, has
much higher concentrations of these materials, mainly because the manure has
not been diluted as much as the domestic waste. The content of nitrogen in this
wastewater generally ranges from 50 to 2,000 milligrams per liter. When
wastewater is applied, checks should be made to ensure that nitrogen, heavy
metals, and salts are not added in excessive amounts.
The ratings are based on the soil properties that affect the risk of pollution and the
design, construction, and performance of the system. Depth to a water table,
ponding, flooding, and depth to bedrock or a cemented pan affect the risk of
pollution and the design and construction of the system. Slope, stones, and cobbles
also affect design and construction. Saturated hydraulic conductivity (Ksat) and
reaction affect performance. Permanently frozen soils are unsuitable for waste
treatment.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and

be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the

Disposal of Wastewater by Irrigation —Swain County Area, North Carolina
Description
Wastewater includes municipal and food -processing wastewater and effluent from
lagoons or storage ponds. Municipal wastewater is the waste stream from a
municipality. It contains domestic waste and may contain industrial waste. It may
have received primary or secondary treatment. It is rarely untreated sewage. Food -
processing wastewater results from the preparation of fruits, vegetables, milk,
cheese, and meats for public consumption. In places it is high in content of sodium
and chloride. The effluent in lagoons and storage ponds is from facilities used to
treat or store food -processing wastewater or domestic or animal waste. Domestic
and food -processing wastewater is very dilute, and the effluent from the facilities
that treat or store it commonly is very low in content of carbonaceous and
nitrogenous material; the content of nitrogen commonly ranges from 10 to 30
milligrams per liter. The wastewater from animal waste treatment lagoons or
storage ponds, however, has much higher concentrations of these materials,
mainly because the manure has not been diluted as much as the domestic waste.
The content of nitrogen in this wastewater generally ranges from 50 to 2,000
milligrams per liter. When wastewater is applied, checks should be made to ensure
that nitrogen, heavy metals, and salts are not added in excessive amounts.
Disposal of wastewater by irrigation not only disposes of municipal wastewater and
wastewater from food -processing plants, lagoons, and storage ponds but also can
improve crop production by increasing the amount of water available to crops. The
ratings are based on the soil properties that affect the design, construction,
management, and performance of the irrigation system. The properties that affect
design and management include the sodium adsorption ratio, depth to a water
table, ponding, available water capacity, saturated hydraulic conductivity (Ksat),
slope, and flooding. The properties that affect construction include stones, cobbles,
depth to bedrock or a cemented pan, depth to a water table, and ponding. The
properties that affect performance include depth to bedrock or a cemented pan,
bulk density, the sodium adsorption ratio, salinity, reaction, and the cation -
exchange capacity, which is used to estimate the capacity of a soil to adsorb heavy
metals. Permanently frozen soils are not suitable for disposal of wastewater by
irrigation.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations

use (1.00) and the point at which the soil feature is not a limitation (0.00).
The map unit components listed for each map unit in the accompanying Summary
by Map Unit table in Web Soil Survey or the Aggregation Report in Soil Data Viewer
are determined by the aggregation method chosen. An aggregated rating class is
shown for each map unit. The components listed for each map unit are only those
that have the same rating class as listed for the map unit. The percent composition
of each component in a particular map unit is presented to help the user better
understand the percentage of each map unit that has the rating presented.
Other components with different ratings may be present in each map unit. The
ratings for all components, regardless of the map unit aggregated rating, can be
viewed by generating the equivalent report from the Soil Reports tab in Web Soil
Survey or from the Soil Data Mart site. Onsite investigation may be needed to
validate these interpretations and to confirm the identity of the soil on a given site.

Disposal of Wastewater by Rapid Infiltration —Swain County Area, North Carolina
Description
Rapid infiltration of wastewater is a process in which wastewater applied in a level
basin at a rate of 4 to 120 inches per week percolates through the soil. The
wastewater may eventually reach the ground water. The application rate commonly
exceeds the rate needed for irrigation of cropland. Vegetation is not a necessary
part of the treatment; thus, the basins may or may not be vegetated. The thickness
of the soil material needed for proper treatment of the wastewater is more than 72
inches. As a result, geologic and hydrologic investigation is needed to ensure
proper design and performance and to determine the risk of ground -water pollution.
Soil properties are important considerations in areas where soils are used as sites
for the treatment and disposal of organic waste and wastewater. Selection of soils
with properties that favor waste management can help to prevent environmental
damage.
Municipal wastewater is the waste stream from a municipality. It contains domestic
waste and may contain industrial waste. It may have received primary or secondary
treatment. It is rarely untreated sewage. Food -processing wastewater results from
the preparation of fruits, vegetables, milk, cheese, and meats for public
consumption. In places it is high in content of sodium and chloride. The effluent in
lagoons and storage ponds is from facilities used to treat or store food -processing
wastewater or domestic or animal waste. Domestic and food -processing
wastewater is very dilute, and the effluent from the facilities that treat or store it
commonly is very low in content of carbonaceous and nitrogenous material; the
content of nitrogen commonly ranges from 10 to 30 milligrams per liter. The
wastewater from animal waste treatment lagoons or storage ponds, however, has
much higher concentrations of these materials, mainly because the manure has
not been diluted as much as the domestic waste. The content of nitrogen in this
wastewater generally ranges from 50 to 2,000 milligrams per liter. When
wastewater is applied, checks should be made to ensure that nitrogen, heavy
metals, and salts are not added in excessive amounts.
The ratings are based on the soil properties that affect the risk of pollution and the
design, construction, and performance of the system. Depth to a water table,
ponding, flooding, and depth to bedrock or a cemented pan affect the risk of
pollution and the design and construction of the system. Slope, stones, and cobbles
also affect design and construction. Saturated hydraulic conductivity (Ksat) and
reaction affect performance. Permanently frozen soils are unsuitable for waste
treatment.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can

be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the
use (1.00) and the point at which the soil feature is not a limitation (0.00).

Disposal of Wastewater by Irrigation —Swain County Area, North Carolina Camp Watia - Site 4
Description
Wastewater includes municipal and food -processing wastewater and effluent from
lagoons or storage ponds. Municipal wastewater is the waste stream from a
municipality. It contains domestic waste and may contain industrial waste. It may
have received primary or secondary treatment. It is rarely untreated sewage. Food -
processing wastewater results from the preparation of fruits, vegetables, milk,
cheese, and meats for public consumption. In places it is high in content of sodium
and chloride. The effluent in lagoons and storage ponds is from facilities used to
treat or store food -processing wastewater or domestic or animal waste. Domestic
and food -processing wastewater is very dilute, and the effluent from the facilities
that treat or store it commonly is very low in content of carbonaceous and
nitrogenous material; the content of nitrogen commonly ranges from 10 to 30
milligrams per liter. The wastewater from animal waste treatment lagoons or
storage ponds, however, has much higher concentrations of these materials,
mainly because the manure has not been diluted as much as the domestic waste.
The content of nitrogen in this wastewater generally ranges from 50 to 2,000
milligrams per liter. When wastewater is applied, checks should be made to ensure
that nitrogen, heavy metals, and salts are not added in excessive amounts.
Disposal of wastewater by irrigation not only disposes of municipal wastewater and
wastewater from food -processing plants, lagoons, and storage ponds but also can
improve crop production by increasing the amount of water available to crops. The
ratings are based on the soil properties that affect the design, construction,
management, and performance of the irrigation system. The properties that affect
design and management include the sodium adsorption ratio, depth to a water
table, ponding, available water capacity, saturated hydraulic conductivity (Ksat),
slope, and flooding. The properties that affect construction include stones, cobbles,
depth to bedrock or a cemented pan, depth to a water table, and ponding. The
properties that affect performance include depth to bedrock or a cemented pan,
bulk density, the sodium adsorption ratio, salinity, reaction, and the cation -
exchange capacity, which is used to estimate the capacity of a soil to adsorb heavy
metals. Permanently frozen soils are not suitable for disposal of wastewater by
irrigation.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations

between the point at which a soil feature has the greatest negative impact on the
use (1.00) and the point at which the soil feature is not a limitation (0.00).
The map unit components listed for each map unit in the accompanying Summary
by Map Unit table in Web Soil Survey or the Aggregation Report in Soil Data Viewer
are determined by the aggregation method chosen. An aggregated rating class is
shown for each map unit. The components listed for each map unit are only those
that have the same rating class as listed for the map unit. The percent composition
of each component in a particular map unit is presented to help the user better
understand the percentage of each map unit that has the rating presented.
Other components with different ratings may be present in each map unit. The
ratings for all components, regardless of the map unit aggregated rating, can be
viewed by generating the equivalent report from the Soil Reports tab in Web Soil
Survey or from the Soil Data Mart site. Onsite investigation may be needed to
validate these interpretations and to confirm the identity of the soil on a given site.

Disposal of Wastewater by Rapid Infiltration —Swain County Area, North Carolina
Description
Rapid infiltration of wastewater is a process in which wastewater applied in a level
basin at a rate of 4 to 120 inches per week percolates through the soil. The
wastewater may eventually reach the ground water. The application rate commonly
exceeds the rate needed for irrigation of cropland. Vegetation is not a necessary
part of the treatment; thus, the basins may or may not be vegetated. The thickness
of the soil material needed for proper treatment of the wastewater is more than 72
inches. As a result, geologic and hydrologic investigation is needed to ensure
proper design and performance and to determine the risk of ground -water pollution.
Soil properties are important considerations in areas where soils are used as sites
for the treatment and disposal of organic waste and wastewater. Selection of soils
with properties that favor waste management can help to prevent environmental
damage.
Municipal wastewater is the waste stream from a municipality. It contains domestic
waste and may contain industrial waste. It may have received primary or secondary
treatment. It is rarely untreated sewage. Food -processing wastewater results from
the preparation of fruits, vegetables, milk, cheese, and meats for public
consumption. In places it is high in content of sodium and chloride. The effluent in
lagoons and storage ponds is from facilities used to treat or store food -processing
wastewater or domestic or animal waste. Domestic and food -processing
wastewater is very dilute, and the effluent from the facilities that treat or store it
commonly is very low in content of carbonaceous and nitrogenous material; the
content of nitrogen commonly ranges from 10 to 30 milligrams per liter. The
wastewater from animal waste treatment lagoons or storage ponds, however, has
much higher concentrations of these materials, mainly because the manure has
not been diluted as much as the domestic waste. The content of nitrogen in this
wastewater generally ranges from 50 to 2,000 milligrams per liter. When
wastewater is applied, checks should be made to ensure that nitrogen, heavy
metals, and salts are not added in excessive amounts.
The ratings are based on the soil properties that affect the risk of pollution and the
design, construction, and performance of the system. Depth to a water table,
ponding, flooding, and depth to bedrock or a cemented pan affect the risk of
pollution and the design and construction of the system. Slope, stones, and cobbles
also affect design and construction. Saturated hydraulic conductivity (Ksat) and
reaction affect performance. Permanently frozen soils are unsuitable for waste
treatment.
The ratings are both verbal and numerical. Rating class terms indicate the extent
to which the soils are limited by all of the soil features that affect agricultural waste
management. "Not limited" indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. "Somewhat limited" indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. "Very limited" indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or

expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings indicate the severity of individual limitations. The ratings are
shown as decimal fractions ranging from 0.01 to 1.00. They indicate gradations
between the point at which a soil feature has the greatest negative impact on the
use (1.00) and the point at which the soil feature is not a limitation (0.00).
The map unit components listed for each map unit in the accompanying Summary
by Map Unit table in Web Soil Survey or the Aggregation Report in Soil Data Viewer
are determined by the aggregation method chosen. An aggregated rating class is
shown for each map unit. The components listed for each map unit are only those
that have the same rating class as listed for the map unit. The percent composition
of each component in a particular map unit is presented to help the user better
understand the percentage of each map unit that has the rating presented.
Other components with different ratings may be present in each map unit. The
ratings for all components, regardless of the map unit aggregated rating, can be
viewed by generating the equivalent report from the Soil Reports tab in Web Soil
Survey or from the Soil Data Mart site. Onsite investigation may be needed to
validate these interpretations and to confirm the identity of the soil on a given site.

ADDENDUM — FACT SHEET NCO089478 Camp Watia WWTP — May, 19 2015
An Authorization to Construct (A to C) application was received 12/12/14 for yet- to- be built domestic
treatment plant for NCO089478 Camp Watia WWTP. The NPDES permit provided a limitation page for
0.012 MGD but the A to C application was for a phase I initial plant operation/design of 0.006 MGD. To
proceed with the A to C permit, a 0.006 MGD limitation page was required in the NPDES permit. After
discussions with the permittee, it was agreed a minor NPDES permit modification would be issued
adding the intermediate 0.006 MGD limitation page with identical limits and monitoring requirements,
except for the flow limit, as stated for the 0.012 MGD limitation page. Because of the addition of the
0.006 MGD flow page, to expand to 0.012 MGD will require the permittee to obtain an A to C permit and
submit a signed Engineer's Certificate for the expansion. Various technical corrections to narratives and
formatting were made whefe required.
