Yea. On this day I observed a line of manholes belonging to the Cane Creek Water and Sewer District of
Henderson County (CCWSDHC) marching right up to the WWTP which formerly served Mills River
Village. Additionally I observed that a pump had been used to pump activated sludge from the plants to
the nearest manhole. One aeration basin was empty. The other has about 1/8 of its normal inventory of
sludge and that sludge was being aerated.
For your future reference I observed a manhole belonging to the CCWSDHC in the rear of the property
occupied by Mills River Texaco. Next door, I observed empty WWTP units at Mills River Restaurant.

Subject: Issuance of NPDES Permit NCO062669
Mills River Restaurant WWTP
Henderson County
Dear Mr. Sellas:
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued
pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of
Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 0,1994
(or as subsequently amended). -
This final permit includes no major changes from.the draft permit sent to you' on September 14,
2005:
➢ The .term of the permit has been reduced from 5 to three years, with an expiration date of
November 30, 2008.
➢ The Daily Maximum limit for Total Residual Chlorine takes effect on July 1, 2007.
Your permit's duration has been reduced for the following reasons:
➢ The Mills River is listed as an impaired stream on North Carolinas 303(d) list. This means
that the stream does not meet all water quality standards.
➢ The City of Asheville has asked the Division to remove your discharge from the stream, as
your outfall is upstream of the City's drinking -water intake [see attached correspondence].
➢ Part III of your permit requires you to "continually evaluate all wastewater disposal
alternatives and pursue the most environmentally sound alternative of the reasonably cost
effective alternatives" to surface water discharge. The attached documentation from the
Henderson County Utilities Department shows that sanitary sewer service will be
available to you in 2006. Given the local opposition to reissuance of your permit, the
Division strongly urges you to connect to local sewer service as soon as it becomes
available.

RE: NPDES permit NCO062669
Dear Ms. Bryant: ;
James S. Erwin, Jr. .
Director
Thank you for providing us with notice that Nikolaos Sellas has applied for renewal of NPDES permit
NCO062669 for the Mills River Restaurant wastewater treatment plant in Henderson County, North
Carolina.
The County of Henderson through its Cane Creek Water and Sewer District (CCWSD) is currently
constructing a sewer collector which will make sewer service available to the Mills River Restaurant
property. The said sewer collector is expected to become operational within about six months.' .
The County of Henderson, through its CCWSD, strongly recommends that the State require the owners
of the Mills River Restaurant wastewater treatment plant to discontinue operating said wastewater
treatment plant and connect their wastewater collection system to the new CCWSD sewer collector as
soon as it becomes operational. The said owners of the Mills River Restaurant wastewater treatment
plant would, of course, be required to file an application with the CCWSD, pay all the appropriate fees
and meet all the other CCWSD requirements before the connection can be made.
Your notice indicates the subject permitted facility discharges treated wastewater to an unnamed
tributary to the Mills River. It is my understanding that the unnamed tributary flows into the Mills River
at a point upstream of a drinking -water intake. If this is the case, elimination of the said wastewater
treatment plant would certainly benefit the affected water users.
If you need additional information please call meat 828-654-7062.
As always, your consideration is greatly appreciated.
Sincerely,

Re: Mills River NPDES
Permits # NCO069671 & N00062669 ;
Dear Ms. Bryant:
The City of Asheville owns and operates the Mills River Water Treatment Plant. This 7.5 mgd
water treatment facility is located in Henderson County at the confluence of the Mills River and
the French Broad River. At present and for the near future, the Mills River is the raw water
source for this water treatment facility.
Currently there are two (2). wastewater treatment discharges into the Mills River upstream of our
raw water intake. We recently learned that the NPDES permits for both these facilities are
coming up for renewal. These peimits'are: (1) NC0069671 for the Mills River Village WWTP
(2) NCO062669 for the Mills River Restaurant.
We are aware that Henderson County is currently constructing sanitary sewer lines within the
.Town of Mills River. According to Mr. Jim Erwin, Henderson County Director of Utilities, these.
sanitary sewer lines will be completed within the next six (6) months. Also, according to Mr.
Erwin, these sewer lines; when complete, will make public sanitary sewer'service available to
both the Mills River Village and the Mills River Restaurant.'
The City of Asheville has operated the Mills River Water Treatment plant for nearly 6 years.
During this time, we have produced a quality product from this facility that meets and exceeds all
applicable drinking water standards. From this standpoint; the previously named upstream
discharges have not adversely impacted the operation of this facility.'
While our water treatment facility has successfully operated with the presence of the current
permitted discharges, we believe that the future water quality of the Mills River and to a lesser
extend, the French Broad River, would be enhanced by the elimination of these permitted
discharges. The wastewater collected by the sanitary sewer lines under construction will
ultimately be conveyed to the Metropolitan Sewerage District of Buncombe County (MSD) for
treatment and discharge. MSD's treatment facilities, personnel and other resources can ensure a

consistently higher wastewater discharge quality than can independently owned and operated
I ackaged wastewater treatment plants..
Elimination of these permitted discharges would remove the chance of future.non compliant
discharges, caused by mechanical failure or other reasons, and would help ensure the water .
quality integrity of the Mills River. This integrity would not only benefit the City of Asheville in
the operation of our water treatment facility, but would benefit all other users of the Mills River
resource.
The City of Asheville is pleased with Henderson County's efforts to make public sewer service
available to current and future homeowners and businesses In the Mills River area. We*
respectively request that the subject NPDES permits be conditioned to require connection the
public sanitary sewer system whenever they are placed into service.
Thank you for your consideration of this matter. If you have any questions or if I can be of
assistance, you can reach me at 828-259-5955.

were a major consideration of the CWMTF Board prior to awarding this grant. .
Public notices of permit renewals have been issued by the Division of Water
Quality for the above -listed three private package plants within the Mills River
area, all of which are within easy reach of the new public system.
Since two of the major purposes of public sewerage utilities are to consolidate and.
eliminate multiple private point source discharges and also to protect public water
supplies, it appears that renewal of any NPDES within the Mills River sewer
service area would be counterproductive and fail to achieve these goals. To
renew these permits would also be to waste the millions in public funds that have
been spent to provide the public sewer service in this area.
The staff of the CWMTF strongly urges the Division not to renew the above -
named NPDES permits and to ultimately require that these facilities be connected
to the publicly owned and operated sanitary sewer system.
We also strongly recommend that any other permit renewals within the Mills
River sewer service area should be denied and the facilities be required to connect
to the public utility upon expiration of their current NPDES permits.
Please let us know if there is any additional information that would be helpful to
you in the review of this issue.

Samples are collected twice per month with at least ten calendar days between sampling events.
3/Week
Samples are collected three times per week on three separate calendar days.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq.
Annual Average
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal
coliform, the geometric mean of such discharges.
Arithmetic Mean
The summation of the individual values divided by the number of individual values.
B ass
The known diversion of waste streams from any portion of a treatment facility including the collection system, which
is not a designed or established or operating mode for the facility.
Calendar Dav
The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any
consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Quarter
One of the following distinct periods: January through March, April through June, July through September, and
October through December.
Composite Sample
A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in
such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The
Director may designate the most appropriate method (specific number and size of aliquots necessary, the time
interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically.
Composite samples may be obtained by the following methods:
(1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow.
(2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24.hour
period of discharge and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period
with the time intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow recorder and
totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the
expected total daily flow at the treatment system, or
(4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at
a constant time interval. This method may only be used in situations where effluent flow rates vary
less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart
during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method
requires prior approval by the Director.
Version 612012003
NPDES Permit
Page 2 of
In accordance with (4) above, influent grab samples shall not be collected more than once per hour.
Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems
having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at
intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the
system in number of days. However, the interval between effluent grab samples may not exceed six hours nor
the number of samples less than four during a 24-hour sampling period.
Continuous flow measurement
Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance
activities on the flow device.
Daily Discharge
The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the
calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as
the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean
concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all
grab samples collected during'that period. (40 CFR 122.3)
Daily Maximum
The highest "daily discharge" during the calendar month.

5. Mass/Day Measurements
a- The "monthly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during a calendar month on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
month It is therefore, an arithmetic mean found by adding the weights of the pollutant found
each day of the month and then dividing this sum by the number of days the tests were.
reported. The limitation is identified as "Monthly Average" in Part I of the permit.
b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are
sampled and measured, divided by the number of daily discharges sampled and/or measured
during such week. It is, therefore, an arithmetic mean found by adding the weights of
pollutants found each day of the week and then dividing this sum by the number of days the
tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit.
c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a
calendar day. If only one sample is taken during any calendar day the weight of pollutant
calculated from it is the "maximum daily discharge." This limitation is identified as "Daily
Maximum," in Part I of the permit.
d. The "average annual discharge" is defined as the total mass of all daily discharges sampled
and/or measured during the calendar year on which daily discharges are sampled and
measured, divided by the number of daily discharges sampled and/or measured during such
year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each
day of the year and then dividing this sum by the number of days the tests were reported. This
limitation is defined as "Annual Average" in Part I of the permit.

6. Concentration Measurement
a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar month on
which daily discharges are sampled and measured, divided by the number of daily discharges
sampled and/or measured during such month (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average monthly' count for fecal coliform bacteria is
the geometric mean of the counts for samples collected during a calendar month. This
limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit.
b. The "average weekly concentration," other than for fecal coliform bacteria, is the .sum of the
concentrations of all daily discharges sampled and/or measured during a calendar week
(Sunday/Saturday) on .which daily discharges are sampled and measured divided by the
number of daily discharges sampled and/or measured during such week (arithmetic mean of the
daily concentration values). The daily concentration value is equal to the concentration of a
composite sample or in the case of grab samples is the arithmetic mean (weighted by flow
value) of all the samples collected during that calendar day. The average weekly count for
fecal coliform bacteria is the geometric mean of the counts for -samples collected during a
calendar week. This limitation is identified as .'Weekly Average" under "Other Limits" in
Part I of the permit.
c. The "maximum -daily concentration" is the concentration of a pollutant discharge during a
calendar day. If only one sample is taken during any calendar day the concentration of
pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily
Maximum" under "Other Limits" in Part I of the permit.
d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the
concentrations of all daily discharges sampled and/or measured during a calendar year on
which daffy discharges are sampled and measured divided by the number of daily discharges
sampled and/or measured during such year (arithmetic mean of the daily concentration
values). The daily concentration value is equal to the concentration of a composite sample or in
the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples
collected during that calendar day. The average yearly count for fecal coliform bacteria is the
geometric mean of the counts for samples collected during a calendar year. This Iimitation is
identified as "Annual Average" under "Other Limits" in Part I of the permit.
e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of
dissolved oxygen required to be available in the effluent prior to discharge averaged over a
calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is
considered to be the "daily average concentration"- for the discharge. It is identified as "daily
average" in the text of Part I.

7. Other Measurements
a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged
monthly. It is determined as the arithmetic mean of the total daily flows recorded during the
calendar month
b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when
both the sample and flow will be representative of the total discharge.
c. A "continuous flow measurement' is a measure of discharge flow from the facility which occurs
continually without interruption throughout the operating hours of the facility. Flow shall be
monitored continually except for the infrequent times when there may be no flow or for
infrequent maintenance activities on the flow device.
8. Types of Samples
a. Composite Sample: A composite sample shall consist of:
(1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge
and combined proportional to the rate of flow measured at the time of individual sample
collection, or
(2) a series of grab samples of equal volume collected over a 24 hour period with the time
intervals between samples determined by a preset number of gallons passing the sampling
point. Flow measurement between sample intervals shall be determined by use of a flow
recorder and totalizer, and the present gallon interval between sample collection fixed at
no greater than 1 /24 of the expected total daily flow at the treatment system, or
(3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow.
In accordance with (1) above, the time interval between influent grab samples shall be no
greater than once per hour, and the time interval between effluent grab samples shall be no
greater than once per hour except at wastewater treatment systems having a detention time of
greater than 24 hours. In such Gases, effluent grab samples may be collected at time intervals
evenly spaced over the 24 hour period which are equal in number of hours to the detention time
of the system in number of days. However, in no rase may the time interval between effluent
grab samples be greater than six (6) hours nor the number of samples less than four (4) during a
24 hour sampling period.
b. Grab Sample: Grab samples are individual samples collected over a period of time not
exceeding 15 minutes; the grab sample can be taken manually. Grab samples must 'be
representative of.the discharge or the receiving waters.
9. Calculation of Means
a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual
values divided by the number of individual values.
b. Geometric Mean: The geometric mean of any set,of values is the Nth root of the product of the
individual values where N is equal to the number of individual values. The geometric mean is
equivalent to the antilog of the arithmetic mean of the logarithms of the individual values.
For purposes of calculating the geometric mean, values of zero (0) shall be considered to -be one
(D.
c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration
times its respective flow divided by the summation of the respective flows.

chlorinator (Flow currently enters from the opposite
direction). The plans should indicate how the tablet
chlorinator is to be situated and connected to the piping
from the clarifier - (or future tertiary unit).
6. Access to the new units is needed since they will be
above ground level.
7. The location of the air injection point into the
filter media was not shown. It is critical that this be
located as close to the bottom of the sand as possible to
assure adequate cleaning, since the backwash rate is
limited by the anthracite.
8. Dual blowers are needed for the air scour.
9. Backwash controls should allow manual backwash as well
as automatic.
