BACKGROUND:
Laurel Season WWTP is a Class II, 100% domestic wastewater treatment system that treats waster
from residential development. The FAA for an expansion of this facility has been approved on
January 14, 2009. Effluent limits have been established based on the Level B model.
The Division of Water Quality determined that the incremental impact of the increased discharge
will not result in contravention of applicable water quality standards or loss of the river's designated
uses. The Division concluded that expansion of the existing treatment plant and continued discharge
to the Laurel Fork is the most feasible alternative.

Steve,
I just faxed you a letter (3 pages) from the consultant regarding the Laurel Seasons Expansion (NC0038041). Fax
contains letter from the POTW and the DOT. I think that based on these letters (refusing connection and the right-of-
way) we should proceed with the expansion. It is a very small expansion from 14,500 gpd to 20,000 gpd and they need
to expand to accommodate new buildings.
Please let me know if you have any questions.
Thank you!

Dear Sergei:
I have finally received letters from the Town of Boone and NCDOT regarding the
comments in your email of March 17, 2009 to me. Copies of these letters are attached.
Regarding your other comments, it is correct that wastewater flow is estimated
based on water records from the well serving the apartments. We believe the estimates to
be fairly accurate and probably less than the water records show, since not all the water
enters the treatment system. As would be required by a plant expansion, we would install
an effluent flow meter.
Regarding a new laundry, I have spoken with the Owner and he is willing to
install only two (2) washing machines for use by the apartment residents. This is down
from the six (6) washing machines stated in my EAA. Additionally, and it was not
mentioned in the EAA, but there are eight (8) existing apartments that already have
washing machines in them.
Please review this additional information and let me know of your comments. I
apologize for the time it has taken to make this reply.

Re: Potential Encroachments
Laurel Seasons Apartments (NC 105) & Green Valley Townhomes (NC 194)
Located in Watauga County
Dear Mr. Coxey:
On April 1, 2009, our office received information concerning possible sewer line extensions for two
existing developments. Said developments being identified as Laurel Seasons Apartment, located on
NC 105 and Green Valley Townhomes, located on NC 194.
In accordance with NCDOT's Policy and Pmcedures for Accommodating Utilities on Highway Rights of
Way, the Department would not approve the longitudinal installation of a private sewer line within the
right of way limits. Longitudinal sewer line installations would only be permitted in the name of a public
utility. Please note that installation along NC 105 could be possible. Construction along NC 194 would
be very difficult, due to narrow typical section along this route.
If you have any further questions, please feel free to contact me at (828) 265-5380.

Dear Mr. Coxey:
This letter is to provide clarification to your request inquiring as to the possibility of our facilities
accepting wastewater from the proposed Green Valley Townhomes located on NC Highway 194
and the Laurel Seasons Apartments located on NC Highway 105. At this time the Town of Boone
has no sewer mains or apparatus located near these areas that could be utilized. As both properties
are located several miles outside the Town Limits, the cost to extend the sewer main that distance
is not feasible at this time.
I hope this information is helpful. If you have any questions, or require any additional
information, please feel free to contact me by telephone at 828-268-6250 or via email at

John,
I have received comments for the Winston-Salem Regional Office regarding two of you
projects and I was wondering if you could respond to them.
Laural Seasons WWTP expansion Request NCO038041
Couple of comments to add to the Staff Report on this expansion request.
The stream in question is very high visibility stream off 105. Numerous complaints
over the past several years from landowners adjacent to the stream. Appears the flow
is estimated from water use records rather than effluent flow monitoring - Is it
true?
Current flow is 100% domestic. Due to past history of complaints the addition of
laundry may be a concern. - How likely is the inclusion of laundry?
The report indicated that DOT would not grant encroachment and that Boone would not
accept the WW. Would appear that these_ documents_ should be sought from DOT and
Boone_ by the applicant _and provided as support evidence that tying onto municipal
is not an option. - Could you please provide these documents to us.
The Ponds Expansion Request NCO050610
Some additional comments relating to the staff -report for this expansion request.
The growth rate information was based off a 2001 report (Draper). I would think that
information to be obsolete and growth numbers should be evaluated using more current
information as it accounts for some 176,000 of the new flow requested. - Could you
please provide any additional rationale.
In addition the EAA list several facilities that will be connecting to the Ponds
WWTP..I would think confirmation of this would be essential and the applicant should
provide letters to that effect from the other facility owners of Smoketree, Country.
House Village, Hawksnest, and Seven Devils as this is 55,000 gallons of the expansion
request. - Please provide confirmation letters.
There is also an issue between the owners of Echota and the Ponds in relation to
ownership of the sewer and pump station form Echota to the Ponds WWTP. This
disagreement could make assignment of responsibility of violations problematic by the
regulatory agencies thus this issue should be resolved prior to any expansion. -
Please provide clarification and documentation regarding this issue.
Thank you!

Sergei,
Couple of comments to add to the Staff Report on this expansion request.
The stream in question is very high visibility stream off 105. Numerous complaints over the past several
years from landowners adjacent to the stream. Appears the flow is estimated from water use records
rather than effluent flow monitoring. The EAA did not include the data to support existing flows. Final
permit should require effluent flow monitoring.
Current flow is 100% domestic. Due to past history of complaints the addition of laundry may be a
concern. Appropriate limits and monitoring should be included in permit to gauge discharge impact if
this activity is included in the new flows.
The report indicated that DOT would not grant encroachment and that Boone would not accept the WW.
Would appear that these documents should be sought from DOT and Boone by the applicant and
provided as support evidence that tying onto municipal is not an option.

The DO standard of 6 mg/1 for the trout classification will be protected in Laurel Fork.
Stream flows were revised based on updated yield information from a 2008 USGS memo

NC0038041Laurel Season WWTP Expansion Permit Application
Subject: NC0038041Laurel Season WWTP Expansion Permit Application
From: Sue White <Sue.White@ncmail.net>
Date: Fri, 23 Jan 2009 14:17:04 -0500
To: Sergei Chernikov <Sergei.Chernikov@ncmail.net>, Steve Tedder <steve.tedder@ncmail.net>
Hi Sergei:
I reviewed the permit application for NC0038041. First I will say that this expansion is badly needed,
both for their existing flow issues and for the fact that this plant was permitted in 1977 and no major
upgrades have been done since. It's actually two plants pieced together.
Comments:
1. Is the new flow limit of 20,000 GPD going to be sufficient? If their projected flow is 16,800 GPD
they're at 84% right off the bat.
2. What parts of the old plant specifically are they planning on using. This plant is not in great shape.
Can we require them to do any structural testing of the basins that they're planning on keeping?
3. Can we require them to completely remove any old components that will not be utilized? The habit
in the mountains is to put a new plant in and leave the old one sitting there.
4. An effluent flow meter should be required.
A staff report was done on this plant in August of 2007, is this current enough? With the exception of
the installation of a grease trap nothing has changed since. If not, I will prepare a new one and get it to
you.
Have a good weekend!

Dear Susan:
Attached please find three (3) copies of the above referenced EAA, application
check in the amount of $260.00, and Local Government Review Forms from Watauga
County and the Town of Boone.
The NPDES Application is enclosed in each copy of the EAA.
Included in the EAA is a comprehensive soils report obtained from the Watauga Soil and
Water Conservation District. This report rates all soils contiguous to the project for rapid
irrigation, slow rate treatment, and irrigation. In all cases, soils are rated very poor for on -site
disposal. It is hoped that this published information will preclude the necessity for use of a soil
scientist for arriving at the same conclusions. The Winston-Salem Regional Office is very aware
of these soils and could be contacted for verification.
Please review this submittal and notify my office of your comments.
Thank you very much.

B. Preliminary Investigation of Water Quality
1. Zero Flow Stream Restrictions
The U. S. Geological Survey was contacted for low flow
characteristics for the Watauga River in the area of consideration.
A summary is shown in the Appendix, Exhibit A.
2. Receiving Stream Classification
The area of Laurel Fork in the vicinity of the project is classified as C;
TR as shown in the Appendix, Exhibit B.
3. Basin wide Water Quality Plan
A copy of the information regarding the Laurel Fork in the area of
M4 consideration is shown in the Appendix, Exhibit C.
There appears to be no limiting factors for further wastewater
discharge.

4. Impaired Waters
A copy of the current 303(d) and 2008 draft 303(d) lists are shown in
the Appendix, Exhibit D. There are no impaired waters on these, lists
in the area of the proposed Laurel Seasons Wastewater Treatment
Plant expansion.
5. Presence of Endangered Species
The U. S. Fish and Wildlife Service was contacted for comment on the
project. We received a letter on November 13, 2008 with general
comments and a list of endangered and federal species of concern. No
specifics were presented in the area of plant expansion or collection
system construction.
New plant construction will take place on the site of the existing
Laurel Seasons plant. This site has been in a constant state of change
since the plant was first built. Adjacent to the plant site is an
apartment complex.
The plant expansion will be constructed in an area of the parking lot
for the apartments; therefore no impact to endangered species is
expected.

II. Flow Proiections
am
The facilities at Laurel Seasons consist primarily of apartments occupied
by students at Appalachian State University. Meter readings currently
no range from 7,000 to 12,000 gallons per day depending on whether school
is in or out of session.
Laurel Seasons is currently permitted for 14,500 gallons per day according
to the NPDES Permit. When school is in session wastewater flow is
approximately 80% of the permitted amount.
There are plans by the property owners to add more apartments, possibly
install a small laundry and add a commercial facility. An estimate of
additional flow is shown below:
6 — 2 Bedroom apartments x 120 gpd/bedroom = 1,440 gpd
6 — washer laundry x 500 gallons/machine = 3,000 gpd
1 — 3000'square commercial facility x
120 gallon/ 1000'square = 360 gpd
4,800 gpd
These new flow amounts combined with the existing 12,000 gpd meter
readings equate to a total of 16,800 gpd.
It is proposed to expand the existing Laurel Seasons plant from 14,500
gpd to 20,000 gpd to allow for existing facilities and new apartment and
commercial construction.

III. Discussion of Waste Treatment Alternatives
A. Connection to an Existing Wastewater Treatment Plant
WO
The only treatment facility (public or private) in the vicinity of the Laurel
Seasons plant large enough to accept flow from the project is the Town of
AM Boone. The nearest connecting point to the Boone collection system is
approximately one (1) mile away. Flow from Laurel Seasons would have
to be pumped along the Highway 105 corridor to this location, which is
am 320' higher in elevation than the existing Laurel Seasons plant. Two (2)
pump stations would be required.
�+ There are two (2) reasons why this alternative is not feasible. First, the
North Carolina Department of Transportation (NCDOT) will not grant an
encroachment permit in their right-of-way of Highway 105 to a private
�+ individual or company. Secondly, the Town of Boone has been contacted
in the past for acceptance of wastewater flow from private entities. The
Town's response has been negative regarding this, as it is not feasible to
add additional capacity to their treatment plant, not to construct additional
collection systems for private individuals or companies.

B. Land Application
The land contiguous to the Laurel Seasons project provides very poor
quality soils for land based wastewater disposal. Both sides of Highway
105 are extremely rocky, steep, and heavily wooded.
Existing septic systems are failing and the Watauga County Health
Department is essentially denying any new applications for septic tank and
drainfield systems. Several property owners are attempting to connect to
the Ponds wastewater plant in the Foscoe area because of soil restrictions.
�► An investigation into the soil types was made by obtaining soil
classification maps from the Watauga Soil and Water Conservation
District. A list of the soils contiguous to Laurel Seasons and
corresponding maps are shown in the Appendix Exhibit E.
Description of their soil characteristics and suitability for land -based
FM disposal are shown and their rated values are shown using a scale of 0.01
to 'l .00, with 1.00 representing the greatest limitation. In almost all the
ratings, the value shown is 1.00, the most limiting category.
The report examines the soil suitability for three land based disposal
methods: rapid infiltration, slow rate treatment, and irrigation. There is a
brief description of each treatment method prior to the ratings for each.
The soil ratings for each method begin on the following pages:
Rapid Infiltration - Page 44
Slow Rate Treatment - Page 53
Irrigation — Page 62
The reviewer is requested to review the treatment description as well as
the ratings.
P"
A map of the study area precedes each disposal discussion.
The severity of the limiting factors shown above, strongly suggest that
land -based disposal would not be feasible.
In addition, it is pointed out that a large amount of suitable land would be
necessary to dispose of, and provide repair area for approximately 20,000
gpd of wastewater. It is very doubtful that enough contiguous land could
ever be found let alone be for sale by the local property owners.

No
OR t
am C. Wastewater Reuse
Reuse of treated wastewater effluent on this project can only be an option
when used in conjunction with a biological treatment system approved
under an NPDES permit. State requirements regarding reuse stipulate that
effluent be tertiary quality. While it is expected that tertiary limits will be
required for plant expansion on this project, the project site and areas
around the project have very limited locations where reclaimed water
could be land applied.
There are scattered locations of a few golf courses, ball fields, very few
crops, etc. but they are in varied locations in the county and the logistics
�+ and transport factors involved in distributing small quantities of reclaimed
water appear to preclude this alternative as an option.

D. Direct Discharge to Surface Waters
7Q 10 and 30Q2 stream flow data has been obtained from the USGS and
are shown elsewhere in this report.
It is expected that, at a minimum tertiary limits will be in effect for plant
expansion.
It is proposed to utilize the existing Laurel Seasons wastewater plant as
�+ part of the overall expansion of facilities. The existing plant would be
converted to an equalization basin or sludge holding tank, or a
combination of both. Additional new construction would be required to
�+ provide a treatment plant capable of treating 20,000 gpd. Dual train units
for aeration and clarification would be part of the new construction. A
tertiary filtration system integral to the aeration/clarification would be
included.
Disinfection would be accomplished with a UV light system.
A permanent stand-by generator with automatic transfer switch would be
installed for use in the event of a power outage.
A schematic diagram of the proposed facilities is shown following this
page along with a map and a project cost estimate for the plant expansion.

IV. Conclusions
No present worth analysis is presented in this report because it is evident that the
only alternative for providing additional waste treatment for this project is to
construct a wastewater treatment expansion at the present Laurel Seasons
treatment site.
Soil maps and soil classifications clearly show the non -suitability of the area's
soils for supporting land based wastewater disposals. The majority of the soils
received the lowest rating possible for land -based disposal.
The Town of Boone sewer system is approximately one (1) mile away and up hill.
IM This alternative would require a series of pump stations and an expansion to the
existing Boone wastewater plant.

Subject: Low -flow characteristics for Laurel Fork [trib?] near Boone
Mr. Coxey,
Page 1 of 2
GX*14W1T ,4
In response to your inquiry about the low -flow characteristics (7Q10, 30Q2) for a location on Laurel Fork near
Boone in Watauga 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 any
previous low -flow determinations for the specific lacetion you identified on Laurel Fork. However, the files do
show some previous estimates for other locations on Laurel Fork tributary that plot on the same stream identified
ow by the lat/long coordinates in your letter dated October 17, 2008:
Sta. 03478881920 Laurel Fork tnb at SR 1107 near Poplar Grove (drainage area 1.21 sgmi), estimated 7Q10 =
0.4 cfs (or 0.31 cfs per sgmi), February 1986
Sta. 03478881950 Laurel Fork trib near Boone (drainage area 1.3 sgmi), estimated 7Q10 = 0.4 cfs (or 0.27 cfs
per sgmi), March 1976
Sta. 03478881955 Laurel Fork bib at mouth near Boone (drainage area 1.38 sgmi), estirated 7010 = 0.4 cfs (or
0.31 cfs per sgmii), July 1985
Your point of interest is about 0.3 mile downstream from where 0347881950 plots on mapping software.
Several pieces of information to consider.,
P" (1) The "most recent' low -flow information published for this area is in a statewide report completed in the early
1990's. It is USES 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
httpl/pubs.er govfusgspubshvspANsp2403. 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 andfor diversions.
If you access the report please note the online report files are provided in the ". DJWU" format and require a
particular L¢ardtech plug-in, also avallable through a link displayed on Iffite page. Cr 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.
(a) In Table 1 of this report, there are 3 nearby sites on Watauga River for which 7Q10 and 30Q2 discharge
estimates are provided. Expressing these estimates as 7Q10 and 30Q2 low -flow yields (flow per square f mle of
drainage area, or cfsm) provides some indication of the yield range that could potentially be applicable to your
�► 1;�J<,n. The'Q1^ loV •pGw yEeSd range is from about 0.22 to about 0.28 osrn (average 0.24 cfsm). Similarly, the
30Q2 low -flow yield range is from about 0.48 to about 0.68 cfsm (average 0.55 cfsrn).
1W (b) Use of the regional 7Q10 equation provided in this report for this area (Hydrologic Area 10) produces 7Q10
flaw estimates with yields equal to about 0.31 cfsm. Similarly, use of the regional 30Q2 equation (using a glean
annual runoff of 2.0 cfsm) produces 3002 flown estimates with yWds equal to about 0.69 can.
Am (2) As you consider the active inform. abon, please be aware of the following note. The above data are based on

since publication of the report In some North Carolina basins, the low -flow conditions observed during the 1998-
2002 and current (2007-08) droughts have resulted in lower tow -flow statistics. No formal statewide investigation
has been completed to document the changes in low -flow statistics since the drought. However, where updated
analyses have been completed for self stations, the changes in pre -draught versus updated 7010
discharges have shown varying percentage changes of decline.
em For example, at a downstream, long-term gaging station on Watauga River near Sugar Grove (station id
03479000, drainage any 92-1 sgrrs), the most recent analysis for [aw-'tow characteristics indicates ft 7Q10 is
19.2 cfs (based on full period of record including the recent drought). This is approximately 7 percent lower than
the 7010 based on the avabble period through the 1997 climatic year, just prior to the start of the 1998 2002
OR drought
0*V
Note: The climatic year is the standard annual period used fbr low -flaw 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 2007 climatic year is from April 1, 2007, through March 31, 2008.
Putting together the above pieces of information suggest the 7Q10 yield in the range of about 0.2 to 0.3 cfsm and
the 3002 yield is in the range of about 0.5 to 0.7 cism. And in the absence of further data and/or analyses, use of
these ranges may be the most appropriate and, in terms of the 7Q10, would be consistent with the yields
associated with previous estimates on Laurel Fork.
Once you determine the drainage area for your specific point of interest, you can apply the yield ranges to obtain
7010 and 3002 flaw estimates for this locaation.
Hope this information is helpful.
M" Thank you.
