A. (2.) ACUTE TOXICITY (QUARTERLY) — MONITOR ONLY
[15A NCAC 02B .0200 et seq.]
The Permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina
Procedure Document entitled "Pass/Fail Methodology for Determining Acute Toxicity in a Single Effluent
Concentration" (Revised-December2010 or subsequent versions). The monitoring shall be performed as a
Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent concentration at which there may be at
no time significant acute mortality is 90% (defined as treatment two in the procedure document). The tests will
be performed during the months of February, May, August, and November. These months signify the first
month of each three month toxicity testing quarter assigned to the facility. Effluent sampling for this testing
must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final
effluent discharge below all treatment processes.
The parameter code for Pimephales promelas is TGE6C. All toxicity testing results required as part of this
permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it was
Performed, using the appropriate parameter code. Additionally, DWR Form AT-2 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Resources
Water Sciences Section/Aquatic Toxicology Branch
1623 Mail Service Center
Raleigh, North Carolina 27699-1623
Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no.later than 30 days after -
the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements performed
in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent
toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream.
Should there be no discharge of flow from the facility during any month, the Permittee will complete the
information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number,
pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the
form. The report shall be submitted to the Water Sciences Section at the address cited above.
Should the Permittee fail to monitor during a month in which toxicity monitoring is -required, then monthly
monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to
quarterly in the months specified above
Should, any test data from either these monitoring requirements or tests performed by the North Carolina Division
of Water Resources indicate potential impacts to the receiving stream, this permit may be' re -opened and modified
to include alternate monitoring requirements or limits.
NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism
survival and appropriate environmental controls, shall constitute an invalid test and will require immediate
follow-up testing to be completed no later than the last day of the month following the month of the initial
monitoring.

6. Description of source water(s) (i.e. groundwater, surface water)
Surface water
7. Describe the treatment process(es) for the raw water:
Water is drawn from the Mills River and pumped to an untreated water storage reservoir
where suspended materials are settled out. The settled water is pumped to the pre-
ozonation system to begin disinfection where ozone gas is used to eliminate pathogens
and other bacterial contamination. The water then flows to the rapid mix and flocculation
basins where aluminum sulfate and sodium hydroxide are added to produce suspended
particles. Sedimentation follows where suspended particles settle to the bottom of the
sedimentation basin. The water then proceeds to another ozonation chamber for further
disinfection as well as taste, color, and odor control. Next, the water flows through filters
containing granular activated carbon where the media traps suspended solids and adsorbs
other organic material in the water. Following filtration, a small amount of sodium
hypochlorite is added for disinfection and to prevent the reintroduction of pathogens into
the drinking water. Enough is added to maintain a minimum residual concentration
throughout the distribution system. Fluoride is added to prevent tooth decay, sodium
bicarbonate and zinc orthophosphate are added for corrosion control and sodium
hydroxide to control pH. The inclusion of sodium bicarbonate also increases the buffering
capacity of water thereby helping to prevent pH swings in the distribution system.
S. Describe the wastewater and the treatment process(es) for wastewater generated by the
facility:
The wastewater is process water primarily from filter backwashes and .periodic sludge
discharges from the sedimentation basins. This wastewater flows to a lagoon where the
suspended solids are allowed to settle and the supernate flows to the river. Each year, a
predetermined amount of sludge solids and liquid is contracted for removal from the
lagoon and the solid/liquid waste is delivered to the local sewerage treatment facility.

SLUDGE MANAGEMENT PLAN
The facility's waste water is primarily generated during the filter backwash process. Treated/filtered
water is used to back flush the filters. The contaminants that are removed plus the water used for
backwashing, drains to one of two lagoons located on the premises. Once in the lagoon, the suspended
solids are allowed to settle to the bottom and the supernatant flows to the French Broad River. In
addition to backwashes, the contamination flushed out during wash ups and spill clean ups, filter
excursions that initiate the filter to waste sequence, leaks and the daily discharge of sludge that
accumulates in the sedimentation basins a so contra ute to slu ge waste generation. Once a year a
commercial firm is contracted to dredge, dewater and remove the sludge from the lagoon. The
liquid/solid waste that is removed is delivered to the local sewerage treatment plant for
processing/disposal.

Dear Mr. Edwards:
Enclosed please find a copy of the Compliance Evaluation Inspection report from the
inspection conducted on September 10, 2010. The facility was found to be in_ compliance with
permit NCO085511.
It was requested that the upstream turbidity sampling point be moved down to the raw
water intake. The Division encourages you to move the current upstream sampling point to the
raw water intake. This point should provide a representative turbidity sample and prove to be
safer for personnel. Please indicate this change on the monthly DMRs (Discharge Monitoring
Reports).
Please refer to the enclosed inspection report for additional observations and comments.
If you or your staff should have any questions, please call me at 828-296-4662.

FACILITY DESCRIPTION:
The City of Asheville — Mills River Water Treatment Plant (formerly: Asheville - Buncombe -
Henderson Regional Water Authority) is a class I Physical Chemical wastewater facility.
Water Plant:
Consists of a conventional 5.0 MGD (7.5 MGD under emergency conditions) water plant which
includes coagulation, flocculation, sedimentation, filtration and disinfection using aluminum
sulfate, sodium hydroxide, sodium hypochlorite, sodium bicarbonate, hydrofluorosilicic acid,
anionic polymer, zinc orthophosphate, calcium hydroxide (lime) and ozone.
Wastewater:
Three filters are routinely backwashed (using — 50,000 gallons of water per backwash cycle), and
three sedimentation basins are periodically cleaned, producing wastewater which is dechlorinated
using sodium thiosulfate and discharged into two, lined, earthen 750,000 gallon (1.5 Mgal total
capacity) lagoons for settling. The overflow / supernatant is discharged to the French Broad
River. Only one lagoon is in use at a time.
Sludge Management:
Sludge is settled, concentrated and dewatered, then hauled by a commercial hauler (Synagro —
Clemmons, NC) to MSD (manhole on Butler Bridge Road) for prior to final disposal.
INSPECTION / LOG:
A review of the files indicates -that the last compliance evaluation inspection was conducted on
4-23-2008 by Jim Reid.
The daily operator log was present on -site and had good notation of daily events and field
testing data.
PERMIT RENEWAL:
The permit expires on 11-30-2011. The Division received your request for permit renewal on
3-15-2010.
Your request to discontinue the weekly monitoring of iron is noted and will be discussed.
EFFLUENT:
The effluent data was as follows:
Settleable solids = < 0.1 ml/I
pH=6.4units
Page # 2

Permit: NCO085511 Owner - Facility: Mills River Regional WTP
Inspection Date: 09/10/2010 Inspection Type: Compliance Evaluation
Chlorine = <20 ug/1
OPERATIONS AND MAINTENANCE / EFFLUENT / SUMMARY:
Mr. Fred 'Edwards, ORC and Water Plant Supervisor, assisted in the inspection and appears to be
operating and maintaining the facility very well.
The effluent appeared to be in compliance with permit limits.
UPSTREAM MONITORING:
The permit states in "Part II - Section D. Monitoring and Records - #1. Representative Sampling"
that "...All samples shall be taken at the monitoring points specified in this permit and,
unless otherwise specified, before the effluent joins or is diluted by any other wastestream,
body of water, or substance. Monitoring points shall not be changed without notification to the
the approval of the Permit Issuing Authority [40 CFR 122.41 (j)].
The upstream sampling point currently being used is located just upstream of the raw water
intake bridge and has proven to be extremely dangerous, as indicated by several incidents .
involving personnel falling into the river. There are deep holes and snakes present and it is
slippery during rain, snow and icy weather. After falling in, it is very difficult to get out
of the river due to the steep, rocky bank.
It was requested that the upstream turbidity sampling point be moved down to the raw water
intake. The Division encourages you to move the current upstream sampling point to the raw
water intake. This point should provide a representative turbidity sample and prove to be safer
for personnel. Please indicate this change on the monthly DMRs (Discharge Monitoring Reports).
SYSTEM PERFORMANCE ANNUAL REPORT (SPAR):
The 2009 System Performance Annual Report was received by the Division on 1-27-2010.
Exemption: Because your facility does NOT treat "municipal wastewater" (defined as: domestic and
industrial wastewater), you are NOT required to submit a System Performance Annual Report.
Note: According to the NPDES permit "Part II -Section E. Reporting Requirements - #12. Annual
Performance Reports" states that "Permittees that own or operate facilities that collect or
treat domestic or municipal waste, shall provide an Annual Report to the Permit Issuing
Authority and to the users / customers served by the Permittee (NCGS 143.215.1 C)."
The legal requirement for submittal of the System Performance Annual Report was introduced into
legislation by the Clean Water Act of 1999 (House Bill 1160) and offers further guidance as
follows:
The owner or operator of any wastewater treatment works or wastewater collection systems that
treats or collect or treat domestic or municipal waste, must provide an Annual Report to its
users or customers and to the Department of Environment and Natural Resources that summarizes
the treatment work's and collection system's performance over a 12 month period.

Dustin Guyer, Brenna Cook, and Fred Edwards
This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
GENERAL COMMENTS:
The laboratory was clean and well organized. The facility has all the equipment necessary to perform the
analyses. Performance testing samples have been analyzed for all certified parameters for the .2009
proficiency testing calendar year and the graded results were acceptable. Technical Assistance
documents for all certified parameters were provided at the time of the inspection..
lll. FINDINGS, REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
obi -- Standard Methods, 191h Edition, 4500 H+ B
Settleable, Solids — Standard Methods, 19" Edition, 2540 F
Comment: Units of measure for pH and Settleable Solids were not on' the benchsheet. The North
Carolina Administrative Code, 15A NCAC 2H .0805 (g) (1) requires, Data pertinent to ,each analysis must
be maintained for five years. Certified Data must consist of.date collected, time collected, samples site,
sample collector, and sample analysis time. The field bench sheets must provide a space for the
signature of the analyst, and proper units of measure for all analyses. An updated benchsheet which
includes units of measure for all parameters was received on December 3, 2009. No further responje
is necessary for this finding.
pH — Standard Methods, 19th Edition, 4500 H+ B
Comment: The temperature correction was not posted on the meter. The Technical Assistance for Field
Analysis of pH document requires that the temperature correction (even if it is zero) must be posted on .
the meter as well as in hard copy format (to be retained for 5 years). Laboratory personnel posted the
temperature correction on the meter during the inspection. No further response is necessary for this
Minding.

Settleable Solids — Standard Methods, 191h Edition, 2540 F
Comment:, The stirring of the Imhoff cone after 45 minutes was not documented. The Technical
Assistance for Field Analysis of Settleable Solids document requires that the 45 minute stir time be
documented. An updated benchsheet which includes this was received on December 3, 2009. No further
response is necessary for this finding.
PAPER TRAIL INVESTIGATION:
The paper trail consisted of comparing laboratory bench sheets and contract lab reports to Discharge
Monitoring Reports (DMRs) submitted to the North Carolina Division of Water Quality. Data were
reviewed for the following months: April, June, and August, 2009. The following errors'were noted:

In order to avoid questions of legality, if is recommended that you contact the appropriate Regional
Office for guidance as to whether an amended Discharge Monitoring Report will be required. A copy of
this report will be forwarded to the Regional Office.
Comment: Temperature analyses have been performed, but the results were not reported on the DMR.
The North Carolina Administrative Code, 15A NCAC 2B .0506 .(b) (3) (J) requires'that the results of all
tests on the characteristics of the effluent, including but not limited to NPDES permit monitoring
requirements, shall be reported on the monthly report forms. After reviewing the permit requirements of
the facility, it was determined that Temperature is not required. The facility. has chosen to no longer
monitor Temperature and has dropped the parameter from their laboratory certification. No further
response is necessary for this finding.
V. CONCLUSIONS:
All of the findings noted during the inspection were adequately addressed prior to the completion of this
report. The inspector would like to thank the staff for its assistance during the inspection and data review
process. No response is required.

Mr. Gary Francies
Mr. Fred Edwards
This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for
the analysis of environmental samples.
II. GENERAL COMMENTS:
The staff is congratulated -for doing a good job of maintaining -the -Field Testing -Certification -program:
The facility has all the equipment necessary to perform the analyses. Most data appeared accurate.
Some further quality control procedures need to be implemented.
III. DEFICIENCIES,.REQUIREMENTS, COMMENTS AND RECOMMENDATIONS:
Total Residual Chlorine:
NOTE: The result of the verification of the internal standard curve was not acceptable, exceeding the
10% and 25% acceptance criteria. It appears the reason the standards did not verify closer to true
value was not because of a problem with the meter but probably due to the manner in which the
standards were prepared. More intermediate working solutions needed to be prepared and also dilution
concentrations that allowed for the use of available pipet volumes. The internal curve has been verified
satisfactorily and the results submitted to this office.
NOTE_: The verification of the internal standard curve did not cover the range of the curve. Standards
of 10, 20, 30, 40, and 50 ug/L were used. This not only failed to cover the range of the stored program,
0-500 Ng/L, but also did not verify to the concentration of the gel standard used as the daily quality
control standard. The newly prepared verification was performed with standards of 20, 30, 100, 200,
and 400,ug/L concentrations. Please note that the present reporting level is now 20,ug/L.
REQUIREMENT:. A verification of the stored calibration curve must be performed annually. This is
performed by verifying the readings of five standards. The concentrations of the five standards must
bracket the concentration of the samples analyzed. One of the standards must have a concentration
equal to or below the lower reporting concentration. It is recommended that the values obtained not
vary by more than 10% of the known value for standards greater than .50µg/L and 256/6 of the true
value for standards less than 50µg/L. If the stored program readings vary by more than the above
acceptance criteria, the stored calibration program should . not be used for quantitation until
troubleshooting is carried out to determine and correct the source of error. Ref: Standard Methods, 18th
Edition - Method 4500-CI G., Method 1020B Quality Control (5) page 1-5and Method 1070D 2.

Page 2
NOTE: A gel standard is analyzed for the calibration verification standard, but the true value of the gel
standard has not been established. This has been completed and the data submitted to this office. The
true value of the currently used gel standard is 182 Ng/L.
REQUIREMENT: Establish the true value of the gel standard by reading the gel standard on a meter
that has just had the internal curve verified. Assign that reading as the true value of the gel standard.
Document this procedure. This procedure must be performed annually (every 12 months) to verify gel
standards that have exceeded the documented expiration date. Each gel standard must be verified
specifically to each meter. Ref: TECHNICAL ASSISTANCE FOR FIELD ANALYSIS OF TOTAL
RESIDUAL CHLORINE.
REQUIREMENT: For analyses that require a series of standards, a standard must be analyzed with
each group of samples to verify the standard curve. It is recommended that this verification standard
be approximately mid range. When the calibration verification standard varies by more than ± 10%, or
is outside the established control limits, whichever is lower, the analysis is out of control. The analysis
must be terminated and the problem corrected. Ref: Standard Methods, 18th Edition - Method 4500-
CI G., Method 1020B Quality Control (5) page 1-5 and Method 1070D 2.
p
NOTE: All of the following comments are new requirements or policies that have been implemented since
the last inspection.
A. COMMENT (New_ Policy): The temperature sensing device on the pH meter has not been
calibrated against a certified or traceable thermometer annually (every 12 months).
REQUIREMENT: All temperature sensing devices on meters must meet NIST specifications for
accuracy or must be calibrated against a MIST or NIST traceable thermometer annually (every 12
months) and proper corrections made and documented. Ref: Standard Methods, 18th Edition - Method
2550 B1. The thermometer reading must be less than 10C from the NIST certified reading to be
acceptable. Ref: TECHNICAL ASSISTANCE FOR FIELD ANALYSIS OF pH.
B. COMMENT (New Policy): The laboratory needs to verify the Automatic Temperature Compensator
(ATC) of the pH meter annually (every twelve months).
REQUIREMENT: There have been some changes made by the Certification Program. We have new
policies for ATC verification of pH meters. The following must be performed on an annual (12 month)
basis:
Automatic Temperature Compensator Check (ATC) for pH meter, performed every 12 months :
1. Take a buffer solution and.cool to below 10°C and read the temperature. Analyze the buffer solution
at that temperature. Document the temperature and the measured pH value obtained on the log sheet.
2. Raise the temperature of the buffer solution to approximately 251C.Document the temperature and
the measured pH value on the log sheet.
3. Raise the temperature of the buffer solution to approximately 35°C. Document the temperature and
the measured pH value on the log sheet.
4. Repeat with additional temperature adjustments and pH readings as necessary to ensure the
temperature usually measured for samples has been bracketed. As the temperature increases or
decreases the value of the buffer must be within ± 0.1 S.U. of the true value of the buffer.
Ref: NC Certification Policy Statement February 2006

IV. PAPER TRAIL INVESTIGATION:
A review of data was conducted. This consisted of comparing field testing records and contract lab
reports to Discharge Monitoring Reports (DMRs) submitted to this Division. Data were reviewed for
November and December 2006 and January 2007. No errors were noted. It appears the facility is doing
a good job of accurately transcribing data. The following items were noted.
C. COMMENT: Values of "ND" (non -detected) are reported on the DMR. This is the manner in which
the contract lab reports data to the facility. In these instances the value must be reported on the DMR
as less than the value in thereporting limit column on the lab report.
NOTE: Values less than the established minimum reporting level were being reported for Total
Residual Chlorine. This was corrected in February 2007.
REQUIREMENT: For analytical procedures requiring analysis of a series of standards, the
concentrations of these standards must bracket the concentration of the samples analyzed. One of the
standards must have a concentration equal to the laboratory's lower reporting concentration for the
parameter involved. For example, if you choose to have a lower reporting limit of 20 Ng/I for a particular
parameter, you must analyze a 20 Ng/I standard and report lower samples as <20 pg/I. Ref: Standard
Methods, 20th Edition - Method 1020 B.10.b.
V. CONCLUSIONS:
This laboratory is doing a good job overall. Correcting the above items should help to produce quality
data and meet certification requirements. The inspector would like to thank the staff for their assistance _
- —in the inspection and data review process. —Please suumif a wriften reply to all lettered comments.

Attached is a summary review of the last 12 months of discharge monitoring reports (DMRs) for your
facility. This summary shows the monthly average permit limit (except pH which is 6.0-9.0 and fecal
coliform which is 200 colonies per 100 ml) and the monthly average calculated value reported for each
required parameter.
A review of the files indicates that the last compliance evaluation inspection was conducted on
1-26-2006 by Starr Slivis.
The permit expires on 11-30-2010, please request a permit renewal 6 months prior to expiration.
The Annual Performance Report has been filed for the year.
There are two lagoons that hold the backwash water from the water treatment plant.
Sludge is removed each year by a contractor (Synagro) and taken to MSD for final treatment and dispsoal.
The effluent data was as follows on the day of the inspection.
Settleable Solids = < 0.1 ml/I
Dissolved Oxygen = 0.25 mg/I
Temperature = 10 degrees Celcius
Chlorine = 13 ug/I
pH = 6.8 units
The following samples were taken during the inspection. The results are pending and will be forwarded if
there are any problems.
Effluent: Total Suspended Solids, Iron and Aluminum
Upstream: Turbidity
Downstream: Turbidity
On -site during the inspection was Fred Edwards, ORC.
The log book was present on -site and had good notation of daily events.
The effluent appeared to be clear, indicating compliance with permit limits.
This facility appears to be well operated and maintained. The operator is doing a good job.

Dear Mr. Weaver,
Please modify the NPDES Permit ## NC 0095511 for the Mills Diver Water Treatment
Facility to reflect recent changes. Although there has been no change in ownership, the
permit should be issued to the City of Asheville rather than the Asheville-Runcombe-
Henderson Water Authority do to the fact that the Authority has been dissolved
Additionally, the physical location has not changed but the mailing address is now 4037
Haywood Road, Mills River, N,C, 28759.
There have been no changes as to the nature and volume of wastewater 1scharged.

French Broad to supplement water supply

Times -News Staff Writer

The Mills River flows with autumn leaves past the intake for the
Regional Water Authority's drinking water plant. (HARRISON
METZGER/TIMES-NEWS)
Zoom
MILLS RIVER -- The clear green water of the Mills River swirls with golden
autumn leaves around the intake for the Regional Water Authority's Mills
River Water Treatment Plant.
Fred Edwards, supervisor of the $30 million facility, walks to the other end
of the concrete intake structure and looks through the trees at the French

French Broad to supplement water supply
e
Broad River about 30 feet away.
"You can tell how clean it looks," Edwards says, pointing to some logs
visible below in the French Broad's swiftly moving current.
Flowing green and only slightly murkier than the Mills, the larger French
Broad will soon supplement drinking water supplies for the authority's
130,000 customers in times of extreme drought when the Mills River's flow
dwindles.
The Regional Water Authority is now doing engineering design work to extend
its intake across the peninsula of land that separates the Mills and French
Broad Rivers. The $350,000 project, expected to be completed next spring,
will allow the authority to draw water from the French Broad to supplement
its supply from the Mills River.
"We're going to continue pulling from the Mills River," said David Hanks,
interim director for water resources for Asheville, which owns the plant.
"We are only going to use the other one (the French Broad) if the Mills
River gets in a drought."
Almost all Henderson County residents who pay water bills get their water
from Hendersonville, which operates its own water treatment plant a mile
upstream on the Mills River. Of the authority's 47,000 connections, only
about 126 are in Henderson County, mostly around Mills River and Fletcher.
But Asheville's move to tap the French Broad, even if only in emergencies,
shows how far water quality in the river has improved in recent years.
Supporters say it will prompt residents to continue to clean up and protect
the French Broad.
"I think just by having it there whether it's used or not will protect the
French Broad River upstream from us," Edwards said.
In the 1960s, the French Broad was considered little better than an open
sewer due to untreated wastes dumped into it by 30 industries and towns
along its banks. The cleanup started in the 1970s when the federal Clean
Water Act required polluters to starting treating and improving their
discharges.
Still, the perception of the French Broad as heavily polluted persisted. In
the early 1980s, the residents of Asheville, concerned about pollution
upstream, voted down a bond referendum to tap the river as the city's main
water source.
In 1995, the N.C. Division of Water Quality did a study which showed the
French Broad was suitable as a water supply. Three years later the state
reclassified the river as WS-IV, the least restrictive designation given to
streams that, although not pristine, still meet drinking water standards.
The Regional Water Authority plant, opened in October 1999, was designed to
draw water from the Mills River just upstream of where it flows into the
French Broad, with the intent of someday tapping the larger river. Water
quality in the French Broad has continued to improve since then, with the
shutdown of the several industrial dischargers. Last year, the state
reclassified the entire French Broad as safe for recreation such as
swimming.
The water authority decided last year to extend the plant's intake into the
French Broad after the drought of 2002 reduced the flow of the Mills River
to a trickle. The plant had to cut back its water production a few times
during the summer of 2002 from its capacity of 5 million gallons per day,
Hanks said.
"Last year the Mills River got really low and it is susceptible to drought,"

,.
he said. "With the Hendersonville plant upstream from us in a severe drought
there is not a whole lot of water left in the Mills River."
Heavy rains that started a year ago and continued through much of the summer
helped recharge underground water supplies and erase many effects of the
nearly five-year drought. But Asheville officials want to have the French
Broad intake ready in the event of future droughts.
The French Broad intake also gives the city another sources in the event one
was contaminated, a consideration after 9-11, Edwards said.
Asheville resident Hazel Fobes is leader of Citizens for Safe Drinking Water
and Air, a group her son founded in the early 1980s to fight plans to use
the French Broad as the city's main water source. Fobes says she knows the
authority has discussed extending the intake as drought insurance, but she
was not aware the decision had been made.
"I would be very dubious of this," she said. "I would want more direct
information from the water authority concerning the facilities at the Mills
River (plant), are they capable of doing a proper job of treatment?"
Hanks and Edwards say the state-of-the-art "ozonation" process used at the
Asheville plant is capable of treating the French Broad's water now and
removing any impurities.
"This plant was designed to treat the French Broad if we ever had to,"
Edwards said.

A. (2) ACUTE TOXICITY MONITORING (QUARTERLY)
The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North
Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A
Single Effluent Concentration" (Revised -July, 1992 or subsequent versions). The monitoring shall be
performed as a Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent concentration at
which there. may be at no time, significant acute, mortality is 90%, (defined as treatment two in the
procedure document). Effluent samples for self -monitoring purposes must be obtained during
representative effluent discharge below all waste treatment. The tests will be performed during the
months of February, May, August, and November.
The parameter code for Pimephales promelas is TGE6C. All toxicity testing results required as part of
this permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it
was performed, using the appropriate parameter code. Additionally, DWQ Form AT-2 (original) is to be
sent to the following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Section
1621 Mail Service Center

Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later
than 30 days after the end of the reporting period for which the report is made.
Test data shall be complete and accurate and include all supporting chemical/physical measurements
performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine
of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of
the waste stream.
Should there be no discharge of flow from the facility during any month, the permittee will complete the
information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit
number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the
comment area of the form. The report shall be submitted to the Environmental Sciences Section at the
address cited above.
Should any test data from either these monitoring requirements or tests performed by the North Carolina
Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re-
opened and modified to include alternate monitoring requirements or limits.

of the wastewater discharged during the sample period.
Act or "the Act"
The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), 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.
Bypass
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 Day

consecutive 24-hour period that reasonably represents the calendar day may be used for sampling.
Calendar Week
The period from Sunday through the following Saturday.
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. Use of this method requires prior approval by the Director. This method may

includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires
the Permittee to install and operate backup or auxiliary facilities only when necessary to achieve compliance
with the conditions of the permit [40 CFR 122.41 (e)].
NOTE: Properly and officially designated operators are fully responsible for all proper operation and
maintenance of the facility, and all documentation required thereof, whether acting as a contract operator
[subcontractor] or a member of the Permittee's staff.
3. Need to Halt or Reduce not a Defense
It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or
reduce the permitted activity in order to maintain compliance with the condition of this permit [40 CFR 122.41
(c)]•
4. Bypassing of Treatment Facilities
a. Bypass not exceeding limitations [40 CFR 122.41 (m) (2)]
The Permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded,
but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject
to the provisions of Paragraphs b. and c. of this section.
b. Notice [40 CFR 122.41 (m) (3)]
(1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall submit prior
notice, if possible at least ten days before the date of the bypass; including an evaluation of the
anticipated quality and effect of the bypass.
(2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as required in

c. Prohibition of Bypass
(1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take
enforcement action against a Permittee for bypass, unless:
(A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage;
(B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities,
retention of untreated wastes or maintenance during normal periods of equipment downtime.
This condition is not satisfied if adequate backup equipment should have been installed in the
exercise of reasonable engineering judgment to prevent a bypass which occurred during normal
periods of equipment downtime or preventive maintenance; and
(C) The Permittee submitted notices as required under Paragraph b. of this section.
(2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take
enforcement action against a Permittee for a bypass as provided in any current or future system -wide
collection system permit associated with the treatment facility.
(3) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse effects,
if the Permit Issuing Authority determines that it will meet the three conditions listed above in
Paragraph c. (1) of this section.
5. Upsets
a. Effect of an upset [40 CFR 122.41 (n) (2)]:An upset constitutes an affirmative defense to an action brought
for noncompliance with such technology based permit effluent limitations if the requirements of
paragraph b. of this condition are met. No determination made during administrative review of claims
that noncompliance was caused by upset, and before an action for noncompliance, is final administrative
action subject to judicial review.
Version 1012912010

DES Permit Standard Conu.
Page 8 o..
b. Conditions necessary for a demonstration of upset: Any Permittee who wishes to establish the
affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs,

c. Burden of proof [40 CFR 122.41 (n) (4)]: The Permittee seeking to establish the occurrence of an upset has
the burden of proof in any enforcement proceeding.
6. Removed Substances
Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of
wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to
prevent any pollutant from such materials from entering waters of the State or navigable waters of the United
States. The Permittee shall comply with all existing Federal regulations governing the disposal of sewage
sludge. Upon promulgation of 40 CFR Part 503, any permit issued by the Permit Issuing Authority for the
utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to incorporate
applicable requirements at 40 CFR 503. The Permittee shall comply with applicable 40 CFR 503 Standards for
the Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the regulation, even
if the permit is not modified to incorporate the requirement. The Permittee shall notify the Permit Issuing
Authority of any significant change in its sludge use or disposal practices.
7. Power Failures
The Permittee is responsible for maintaining adequate safeguards (as required by 15A NCAC 21-1.0124) to

means of alternate power sources, standby generators or retention of inadequately treated effluent.
Section D. Monitoring and Records
1. Representative Sampling
Samples collected and measurements taken, as required herein, shall be characteristic of the volume and
nature of the permitted discharge. Samples collected at a frequency less than daily shall be taken on a day and
time that is characteristic of the discharge over the entire period the sample represents. All samples shall be
taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins
or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed
without notification to and the approval of the Permit Issuing Authority [40 CFR 122.41 (j)].
Reporting
Monitoring results obtained during the previous month(s) shall be summarized for each month and reported
on a monthly Discharge Monitoring Report (DMR) Form (MR 1,1.1, 2, 3) or alternative forms approved by the
Director, postmarked no later than the last calendar day of the month following the completed reporting
period.
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 commencement of discharge. Duplicate signed copies of
these, and all other reports required herein, shall be submitted to the following address:

PART II
STANDARD CONDITIONS FOR NPDES PERMITS
Section A. Definitions
2/Month
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.
Bypass
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 Requirements
Page 2 of 16
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)
DOy Maximum
The highest "daily discharge" during the calendar month.
Daily Sampling
Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the
permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other
disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week
for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s).
DWO or "the Division"
The Division of Water Quality, Department of Environment and Natural Resources.
EMC
The North Carolina Environmental Management Commission.
Facility Closure
The cessation of wastewater treatment at a permitted facility, or the cessation of all activities that require coverage
under the NPDES. Completion of facility closure will allow this permit to be rescinded.
Geometric Mean
The Nth root of the product of the individual values where N = the number of individual values. For purposes of
calculating the geometric mean, values of "0" (or "< [detection levq'� shall be considered =1.
Grab Sample
Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be
collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream
samples).
Hazardous Substance
Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act.
Instantaneous flow measurement
A measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total
discharge.
Version 612012003

NPDES Permit Requirements
Page 3 of 16
Months Average (concentration limitl
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal
coliform, the geometric mean of such discharges.
Permit Issuing Authority
The Director of the Division of Water Quality.
Quarters Average (concentration limitl
The average of all samples taken over a calendar quarter.
Severe property damage
Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable,
or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a
bypass. Severe property damage excludes economic loss caused by delays in production.
Toxic Pollutant:
Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act.
11set
An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with
permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by
operational. error, improperly. designed treatment facilities, inadequate treatment facilities, lack of preventive
maintenance, or careless or improper operation.
Weekly Average (concentration limitl
The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar week. In the case of fecal
coliform, the geometric mean of such -discharges.

Dear Mrs. Sprinkle:
Please renew the NPDES permit # NCO085511 for the Mills River Water Treatment
Facility. There are no expected changes in the nature and volume of the waste to be
treated. Attached are the completed application forms and our sludge management plan.
Additionally, the existing permit requires weekly monitoring for both iron and aluminum.
We use an aluminum based coagulant in our water treatment process, so monitoring for
aluminum in our process wastewater,in�certainly applicable. We do not use an iron based
coagulant such as ferric chloride in out water treatment. We monitor for iron biweekly,
both in ourraw water entering the water'treatment process and the potable finished water
as required by the Public Water Supply Section. The concentration of iron in the raw
water, the finished water, and the process wastewater is negligible.
Please consider:eliminating the weekly monitoring of iron in this permit. Thanks for
your consideration.
Sincerely,
Leslie Carreiro
Water Quality/Production Superintendent

At the Mills River Water Treatment Facility a plan to dispose of sludge has
been formulated.
In 1996 a local engineering firm was retained to conduct a sludge
management and disposal study for the water treatment facility. The
information contained in the report has been and will continue to be useful
in our sludge management program,
The Mills River Water Treatment Facility has been designated and is
operated in a manner to minimize the production of large amounts of
sludge. We concentrate and dewater the sludge in the.lagoons annually or
more often if needed. A commercial firm performs the pumping of the
sludge from the lagoons and'disc harges into an approved manhole of the
Metropolitan Sewerage District.

The provision of a means of draining the raw water storage directly to
the lagoon discharge without having to pass through the lagoons was
recommended and discussed with Steve Fehniger of CDM. He anticipated
that a provision for this option would be added as an optional means of
draining the raw water storage. This would allow the direct discharge
of raw water storage drainage to the extent that the discharge would
meet effluent limitations and not cause water quality concerns in the
French Broad River, instead of routing 100% of the volume through the
lagoons, which might overload the settling lagoons.

Mills River Regional Water Treatment Facility
A fter many years of searching for a new water supply source, the
/— %Asheville -Buncombe Water Authority entered into an agreement
during 1994 with Henderson County to construct a regional water treat-
ment plant. at a site on the Mills River. This new plant went into operation
in October 1999 with a million -gallon -per -day capacity to meet projected
water supply requirements for the next 10 to 20 years. The plant is
designed to accommodate expansion to satisfy additional water supply
requirements of up to 30 million gallons per day. The Mills 'River Regional
Water Treatment Facility will help provide the City of Asheville, Buncombe
County, and Henderson County with reliable, safe drinking water.
The Mills River Watershed covers 47,440 acres in Henderson and Tran-
sylvania Counties with approximately 75 percent being in the Pisgah
National Forest. Water quality in the basin is excellent. In 1998, the Mills
River Partnership was formed from various stakeholders in the region.
The goal of this partnership is to preserve and protect the water quality in
the Mills River Watershed. This commitment will help ensure long-term
watershed protection.
The Mills River plant includes an education center, administration building
and laboratory, and a state-of-the-art approach to water treatment high-
lighted by the use of ozone and granular activated carbon (GAC) to en-
sure compliance with all existing and projected Safe Drinking Water Act
regulations. The process is as follows:
Raw water is taken from the Mills River by
ke structure, containing rough
i fine screening systems,
yhere large suspended -
and/or floating materials
are removed.
• The screened water is
then pumped to a 25-
million-gallon raw water
reservoir. °
• The raw water is then
pumped to the preozon
ation system, where it is
contacted with dissolved
one to provide oxidation re-
s necessary to begin de-
activating any bacteria, cysts, and
viruses in the river water.
The partially disinfected water then
flows to the rapidmix system, where
high-speed mixers combine caustic,
alum, and ,polymer in order to chemi-
cally and physically unite with the re-
maining impurities to produce discrete
suspended particles.
The water then passes to the floc-
culators, where it is stirred to allow the
suspended particles to further floc-
culate and coagulate into large, denser
par-ticles that are heavier than water
and can be effectively separated from
the water by gravity.
Ozone Generator
• The water then proceeds to the sed- Equipment
imentation basins, where the suspended
particles are settled, collected, and removed.
• The water then moves through the intermediate ozonation system
where it is contacted with ozone gas to provide an additional level of
disinfection.

The ozonated water then goes through the filters consisting of a
layer of sand topped with a layer of GAC, where the remaining fine
suspended matter (turbidity) is trapped and removed. GAC also
removes natural, organic taste- and odor -causing compounds and
any other undesirable compounds.
Continued on hark

The filtered water is then disinfected, the pH is adjusted, and it is
pumped to the clearwell, where it is stored and held for at least 30
minutes to complete the disinfection process. The finished water is
then pumped to the water distribution system for use by
customers.
The Mills River plant has a sophisticated computer system developed
to control and provide data for the multiple processes that are required
to treat raw water as it moves through the plant system. The system is
linked to and can transfer data between the Mills River plant and the
North Fork Water Treatment Plant. This helps to ensure a fully
integrated and operational system that is designed and engineered to
-. aximize service reliability, minimize operations and maintenance
)sts, improve work force efficiency, limit future expansion costs, and
improve water quality.
The Mills River Regional Water Treatment Facility ensures that
residents of the area continue to enjoy exceptionally high quality
drinking water well into the 21st century.

PART 3 EXECUTION
3.01 PREPARATION
A. Test Pits
Perform exploratory excavation work (test pits) for the purpose of verifying the
location of underground utilities and structures and to check for unknown utilities and
structures, prior to commencing excavation work.
2. Test pits shall be backfilled as soon as the desired infomlation has been obtained.
Backfilled surfaces shall be stabilized in accordance with approved erosion and
sedimentation control plans.
B. Groundwater Observation Wells
Prior to excavation, install one groundwater observation well at the center, or adjacent
thereto of each structure under construction for the purpose of measuring water levels
during excavation. The observation well shall consist of a screen, casing and cap of
approved size and materials of construction. The observation well shall be placed in a
2-1h-in bore hole which shall be carried to an elevation at least to final bottom grad of
structure. The annular space surrounding the intake point and the riser pipe shall be
sealed in such a way as to prevent infiltration from surface water. The observation
well shall be developed in such a manner as to insure proper reflection of subsurface
water levels adjacent to the well.
2. Maintain the observation wells and observe and record the elevation_ of groundwater in
them until the adjacent structure is completed and backfilled. Each observation well
02200-5

V.
6401-09
4/96
shall be observed and recorded daily. Measurements shall be supplied daily to the
Engineer. The Engineer may require that the observation wells reflect true
groundwater levels by adding water to the well recording the drop in level from the
time the water was added. A plugged observation well shall be redeveloped as
necessary to reflect true groundwater levels.
Observation wells shall be abandoned when directed by the Engineer and in a manner
acceptable to the Engineer.
C. Dewatering and Drainage Systems
Temporary dewatering and drainage systems shall be in place and operational prior to
beginning excavation work.
2. At all times during construction provide and maintain proper equipment and facilities
to remove all water entering excavations and keep such excavations dry so as to obtain
a satisfactory undisturbed subgrade foundation condition until the fills, structures or
pipes to be built thereon have been completed to such extent that they will not be
floated or otherwise damaged by allowing water levels to return to natural. levels. The
Contractor shall engage a Geotechnical Engineer to design the dewatering system.
3. Dewatering shall at. all times be conducted in such a manner as to preserve the
undisturbed bearing capacity of the subgrade soils at proposed bottom of excavation.
Well or sump installations shall be constructed -with proper sand filters to prevent
drawing of finer grained soil from the surrounding ground.
4. Water entering the excavation from surface runoff shall be collected in shallow ditches
around the perimeter of the excavation, drained to sumps and pumped from the
excavation to maintain a bottom free from standing water.
5. Take all additional precautions to prevent uplift of any structure during construction.
6. Drainage shall be disposed of in an approved area only so that flow or seepage back
into the excavated area wEL be prevented.
7. Flotation shall be prevented by maintaining a positive and continuous operation of the
dewatering system. The Contractor shall be fully responsible and liable for all
damages which may result from failure of this system.
8. Remove the dewatering equipment after the system is no longer required.
9. Take all necessary precautions to preclude the accidental discharge of fuel, oil, etc in
order to prevent adverse effects on groundwater quality.

3.02 EXCAVATION SUPPORT
A. Fumish, install, monitor and maintain excavation support (e.g., shoring, sheeting, bracing,
trench boxes, etc) as required by Federal, State or local laws, ordinances, regulations and
safety requirements. Support the sides of excavation, to prevent any movement which could
in any way reduce the width of the excavation below that necessary for proper construction,
and protect adjacent structures from undermining, settlement or other damage. Take care to
prevent the formation of voids outside of sheeting. If voids occur behind sheeting,
immediately backfill and compact the voids with common fill material. Voids in locations
that cannot be properly compacted upon backfilling shall be filled with lean concrete.
B. Install excavation supports outside the neat lines of foundations. Supports shall be.plumb
and securely braced and tied in position. Excavation support shall be adequate to withstand
all pressures to which the supports will be subjected. Any movement or bulging of supports
shall be corrected to provide the necessary clearances, dimensions and structural integrity.
C. Excavation Supports Left in Place
Excavation supports that are required to remain in place, if applicable, are indicated on
the Drawings.
2. The Owner or Engineer may direct that certain excavation supports remain in place, or
be cut off at any specific elevation. Supports directed by the Owner or Engineer to be
left in place and not so designated on the Drawings or otherwise specified herein to
remain in place, will be paid for in accordance with Article 11 of the General
Conditions. If the Contractor believes that such a directive increases Contractor's cost
and would thereby entitle Contractor to a change in contract cost, Contractor shall
notify the Engineer in accordance with the applicable article(s) in the General
Conditions pertaining to changes in the work.
3. The right of the Owner or Engineer to direct that certain excavation supports remain in
place shall not be construed as creating any obligation on the Owner or Engineer to
give such direction, nor shall failure to give such direction relieve the Contractor from
liability for damages to persons or property occurring from or upon the work
occasioned by negligence or otherwise, growing out of a failure on the part of the
Contractor to leave in place sufficient excavation supports to prevent any movement of
the ground or damage to adjacent structures.
D. Excavation supports shall be carefully removed in such manner so as not to endanger the
Work or other adjacent structures, utilities, or property. All voids left or caused by
withdrawal of supports shall be immediately filled with sand and compacted.
3.03 ROCK AND BOULDER EXCAVATION
A. A pre -construction survey shall be conducted on and reported for all major structures within
the influence range of any blasting operations or within a minimum of 200 feet whichever is
02200-7

6401-09
4/96
greater, from any blast site. The survey shall consist of a visual inspection and recording by
notes and photographs of cracks or other structural damage previously sustained, and shall be
conducted by a qualified technician furnished by the Contractor's Insurance Underwriter. A.
copy of all notes and photogr4hs shall be submitted to the Owner prior to the beginning of
blasting operations. The records so obtained shall be retained in the Contractor's file for at
least one year after completion of the Contract. In the event of damage claims, a report shall
be prepared by the Contractor on the particular structures as requested by the Engineer from
those notes and photographs and submitted to the Owner.
B. Rock excavation shall be understood to mean ledge rock which in the opinion of the
Engineer requires for its removal, drilling and blasting, wedging, sledging or barring and
boulders which in the opinion of the Engineer require blasting for removal. Rock excavation
shall be made to the widths and depths directed by the Engineer in the field.
C. Boulder excavation shall be understood to mean only boulders in any kind of excavation
exceeding 1 cu yd in volume which can be excavated without resorting to blasting.
D. All blasting operations shall be conducted in full compliance with all the laws of the State,
all local ordinances and with all possible care so as to avoid injury to persons and property.
The rock shall be well covered and sufficient warning shall be given to all persons in the
vicinity of the work before blasting. Care shall be taken to avoid injury to all water pipes,
gas pipes, or other structures and to private property. The Contractor, in addition to
observing all municipal and other ordinances relating to the storage and handling of
explosives, shall also conform to any further regulations which the Engineer shall deem
necessary.
E. If rock below grade is shattered on account of holes having been drilled too deep or too
heavy charges of explosives used or for any other reasons due to blasting by the Contractor,
and if, in the opinion of the Engineer, said shattered rock is unfit for foundation, the
shattered rock shall be removed and the excavation refilled as required by the Engineer at
the expense of the Contractor.
F. Where rock is encountered, it shall be uncovered but not excavated until measurements have
been made by the Engineer.
G. Payment for rock and boulder excavation shall be as established in the Bid Form and as
described in Section 01150 Measurement and Payment.
3.04 STRUCTURAL EXCAVATION PROCEDURES
A. Excavations for structures shall be suitably wide for construction of the structures, including
excavation supports, dewatering and drainage systems and working clearances.
B. Excavation shall be performed in -the -dry and shall be accomplished by methods which _
preserve'the undisturbed state of subgrrde soils. Drainage and dewatering systems shall be in
place and operational prior to beginning excavation work. In no case shall the earth be
02200-8

6401-09
4/96
plowed, scraped or excavated by any means so near to the finished subgrade that would
disturb the finished subgrade. Hand excavation of the final three to six inches may be
required to obtain a satisfactory, undisturbed subgrade. Subgrade soils which become soft,
loose, "quick", or otherwise unsatisfactory for support of structures as a result of inadequate
excavation, dewatering, or other construction methods shall be removed and replaced with
lean concrete, compacted structural fill or suitable crushed rock, subject to prior approval by
the Engineer, at no additional cost to the Owner.
C. Subgrade Preparation
All structures unless otherwise shown on the Drawings or otherwise specified
elsewhere in this Section:
a. Roughly level and proof roll these areas with a 25 ton roller, (or the equivalent)
zn
making at least four passes (two passes being perpendicular to the others).
b. Compact the top 12-in of subgrade to a minimum of 98 percent modified proctor
(ASTM D1557).
C. Where structures are supported by piles, compact the top 12-in of subgrade to a
minimum of 95 percent standard proctor (ASTM D698).
2. Where existing subgrade contains a significant amount of clay. or cohesive soils, over -
excavate sufficiently below the bottom of structure for placement of a lean concrete
working mat. Prior to placing the lean concrete working mat, compact the top 12-in
of existing subgrade to a minimum of 95 percent modified proctor (ASTM D1557).
D. When excavations have reached the required subgrade, including any allowances for worsting
mats or base materials, prior to the placement of working mats or base materials, notify the
soils testing laboratory to verify the suitability of the existing subgrade soils for the
anticipated foundation and structural loadings. If the existing subgrade soils are determined
to be unsuitable, direction will be provided by the Engineer regarding removal and
replacement with suitable materials. If Contractor believes that such direction would
increase Contractor's cost and would thereby entitle Contractor to a change in Contract cost,
Contractor shall notify the Engineer in accordance with the applicable article(s) in the
General Conditions pertaining to changes in the work.
E. Over -excavation beyond the limits and depths required by the Contract Documents shall be
replaced at no additional cost to the Owner by [lean concrete] [structural fill] [bedding rock]
or other approved material subject to the prior approval of the Engineer.
3.05 GENERAL F]LLLNG AND BAC=LING PROCEDURES

3.10 TRENCH EXCAVATION AND BACKFILLING
A. Excavation for all trenches required for the installation of pipes and ducts shall be made to
the depths indicated on the Drawings and in such a manner and to such widths as will give
suitable room for laying, the pipe or installing the ducts within the trenches, for bracing, and
supporting and for pumping and drainage facilities. Contractor shall render the bottom of the
02200-11

6401-09
4/9 6
excavations firm and dry and in all respects acceptable to the Engineer. Bituminous
pavement, when encountered, shall be cut with pneumatic chisels along smooth and straight
lines before excavating. Saw -cutting is required on asphaltic concrete.
B. Rock shall be removed to a minimum 6-in clearance around the bottom and sides of all the
pipe being laid.
C. Where pipe or ducts are to be laid in gravel bedding. or encased in concrete, the trench may
be excavated by machinery to, or just below the designated subgrade provided that the
material remaining in the bottom of the trench is no mom than slightly disturbed.
D. Where pipe or ducts are to be laid directly on the trench bottom, the lower part of the
trenches in each shall not be excavated to grade by machinery, the last of the material being
excavated manually in such a manner that will give a flat bottom true to grade so that pipe
or duct can be evenly supported on undisturbed material. Bell holes shall be made as
required.
E. The Contractor shall meet the following criteria when his/her installation method includes the
use of.a steel box:
I. When installing rigid pipe (R.C., D.I., etc), any portion of the box extending below
mid diameter shall be raised above this point prior to moving the box ahead to install
the next pipe. This is to prevent the separation of installed pipe joints due to
movement of the box.
2. When installing flexible pipe (PVC, ABS solid wall, ABS truss, etc.), the bottom of
the box shall not extend below mid diameter. This is to prevent loss of soil between
the box and the pipe bedding which could result in excessive deflection of the
installed pipe.
F. Backfilling over ducts shall begin not less than three days after placing concrete encasement.
G. Where pipe is to be installed in fill of any type, fill shall be placed and compacted to the
total depth required (rough grade elevation) and then re -excavated for pipe installation.
H. As soon as practicable after the pipe has been laid and jointed, backfMing shall being and
thereafter be prosecuted expeditiously. If required, ash shown on the Drawings, screened
gravel shall be placed around the pipe to mid -diameter. As the screened gravel is placed, it
shall be compacted by suitable tools.
After the screened gravel bedding (if required) has been placed to the mid -diameter of the
pipe, selected common fill as shown shall be placed to a depth of 1-ft over the top of the
pipe. Material shall be thoroughly compacted by hand -tamping as placed with at least one
man tamping for each man shoveling material into the trench.
02200-12

6401-09
4/96
J. Where the pipes are laid in unpaved areas, the remainder of the trench shall be filled with
common fill in layers not to exceed l-ft, and thoroughly compacted by rolling ramming or
puddling, sufficiently to prevent subsequent settling. The backfill shall be mounded 6-in
above the existing grade or as directed. Wherever a loam or gravel surface exists prior to
excavations, it shall be removed, conserved and replaced to the full original depth as part of
the work under the pipe items. In some areas it may be necessary to remove excess material
during the clean-up process, so that the ground may be restored to its original level and
condition. If the Contractor prefers not to store loam, gravel, or topsoil he/she shall replace
it with material of equal quality and in equal quantity.
K. Where the pipes are laid in streets, or other paved areas, the remainder of'the trench above
the bedding and up to a depth of 1-ft below the bottom of the specified paving shall be
backfilled with common fill in 6-inch (max.) layers thoroughly compacted by rolling, or
ramming as the Engineer may direct. The 1-ft layer below the bottom of the specified
paving shall be of concord (pit) gravel of ABC stone, compacted in 6-in layers.
L. Along the length of all pipeline and duct trenches the Contractor shall construct impervious
dams or bulkheads of clay or concrete in the trench bottom at 300-ft intervals or at manholes
and structures, whichever is less, to obstruct the free flow of groundwater after construction
is completed. Provide impervious dams at all points where a pipe trench enters an excavated
area where a perrnanent underdrain system is installed.
M. Compacted backfill shall have an in -place density of at least 8517o of maximum dry density
as measured by a standard proctor test described in ASTM D-698. Compacted backfill
within paved areas shall have.an in -place density of at least 95% of the maximum dry
density using the standard proctor test.

degrees F).
Adhesive seamed specimens shall be conditioned for a minimum of 24 hours at 23 degrees C (73.4
degrees F). After this period, if it appears that the adhesive seam is not dry and suitable for testing,
the seams may be placed in a circulating oven at70 degrees C (158 degrees F) for 3 hours and
allowed to rest at 23 degrees C (73.4 degrees F) for 48 hours before retesting.'.
12.2 Procedure
Place the specimen symmetrically in the clamps of the machine (see Figure 1) with the longer
dimension parallel to and the shcrter dimension at right angles to the direction of application of the
force.
The rate of loading shall be at the rate of 12 plus or minus 0.5 in/minimum (5 plus or minus 0.1
mm/s).
Record the maximum stress applied to the specimen at yield or breakage.
4.02 SOIL, BURIAL
ASTM D3083, Paragraph 9.5 is modified to be:
The test value of the after -exposure specimen shall be based upon the precut sample dimension.
The test method used to determine before and after exposure tensile properties shall be the test
method specified in the materials properties tables for the tensile properties of the material.
Specimens are to be prepared and buried vertically to a depth of 5 inches and exposed as specified
in ASTM D3083, Paragraph 9.5.
Tests for Unsupported Materials:
Testing shall be conducted on specimens prepared from the actual flexible membrane liner.
Tests for Supported Materials:
Fabric: Testing shall be conducted on specimens of the fabric used in the supported sheet. Six
specimens (4-in wide by 6-in long) shall be prepared, three in the warp direction and three in the fill
direction. When testing the fabric by itself (no polymeric membrane coating) before and after soil
burial, it will be necessary to make sure slippage does not occur. This can be done by using tape,
02776-11

6401-9
4/96
sandpaper or cloth material, special jaws, etc. It is also important to note that consecutive fibers
that are grabbed in one jaw correspond to exactly the same fibers grabbed in the other jaw.
Sheet Material: Testing shall be conducted on 60 mil unsupported sheet prepared from the sheeting
or coating compound used to produce the supported flexible membrane liner.
Tests for Factory Seams:
Testing shall be conducted on specimens prepared from actual flexible membrane liner factory
fabricated seams with sealed edges.
4.03 PEEL ADHESION
ASTM D413 shall be modified to be:
Strip specimen Type A, 180 degree peel, modified to be 1-in sample width pulled at a rate of
2-in/minute. Use bonding technique employed in seam joint construction.
4.04 PLY ADHESION
ASTM D413 Section and Procedure, Paragraph 9.1 Strip Specimens - Type A, 180 degrees
peel -...The next sentence shall be deleted and substituted in its place:
The cut strip shall be 1-in wide measured to the nearest 0.0l-in.
ASTM D413 Section 12, Calculations, Paragraph 12.2 shall be modified to be:

To determine the ability of factory seam joints to withstand constant stress under load at room
temperature (73 degrees F).
B. Test Specimen
The supported specimen size shall be a 4-in width of the seam joint and a 12-in length, sufficient to
fit in the clamps of the testing machine. The unsupported specimen size shall, be a 1-in width of the
seam joint and an 8-in length.
02776-12

6401-9
4/96
C. Procedure
The clamping me-chanism will grip a 1-in wide section and should be centered in the width of the
test specimen, above and below the seam joint. The clamps shall not grip any portion of the
overlap area of the seam joint.
1. Room Temperature Test: A designated load shall be applied to seam joint after it is fastened
in the clamps. This load shall be equal to a percentage of the Bonded Seam Strength Value
indicated in the Materials Properties Tables. The load shall be maintained for 4 hours at a
temperature of 73 degrees F. The stressed sample must be closely observed. Excessive
elongation may require clamp adjustment to maintain consistent loading. When elongation
reaches SO percent of the original jaw separation, no additional adjustment need be made.
Retain existing load for balance of test duration.
2. A "failure" will be noted when the seam joint separates entirely.
D. Reporting Results
The results shall be reported by indicating the designated load, the temperature, the time duration of
the test, the length of the overlap seam, and a "pass" or "fail" designation.
4.06 DEAD LOAD SEAM STRENGTH AT ELEVATED TEMPERATURE
A. introduction
Sun exposure and high air temperatures sometimes result in the portion of an exposed Flexible
Membrane Liner (FML) above the water (or contained fluid) surface to reach temperatures over
120 degrees F. If seams are improperly made and/or the FML material formula will not allow good
seams to be made, then the lining may separate under temperatures and forces sometimes
encountered in actual service. The dead load seam strength test at elevated temperature is designed
to identify seams which are likely to be subjected to failure under such conditions.
The temperature selected for the test should be consistent with the thermal physical/chemical
properties of the FML and the anticipated service condition. The temperature and load given in this
test method may need to be revised. The FML materials manufacturer should be consulted if
.changes in the test conditions appear appropriate.
B. Test Specimen
Unsupported Materials: The specimen shall be 1-in wide and at least 9-in long. The seam shall be
located in the center'of the specimen and across the full width of the specimen.
Supported Materials: The specimen shall be 4-in wide and at least 12-in long. The seam shall be
in the center of the specimen and across the full width of the specimen.

PROJECT DESCRIPTION
Background
In June 1994, the Asheville -Buncombe Water Authority .(Authority) and Henderson
County entered into a regional water agreement to construct the Mills River
Regional WTF at the confluence of the Mills River and the French Broad River in
Henderson County to provide the Authority and the County a reliable, long-term
water supply. The location of the site is shown on Figure1. The Mills River
Regional WTF will be designed to provide conventional treatment including rapid
mix, flocculation, sedimentation, and dual -media filtration. Ozonation facilities will.
be provided. Sludge lagoons will also be constructed.
Filter Backwash Water, Sedimentation Basin Draw -off Intake Sluicing Water, &
Treatment Basin Drain Handling Plan
The proposed discharge to the French Broad River will be composed of waste
process water from the Mills River Regional WTF. The water used for filter
backwashing, filter to waste, sedimentation sludge draw -off, river intake sluicing,
and treatment basin drains will flow to the sludge lagoons where solids will be
separated by settling. The decant from these lagoons will be piped to the French
Broad River.
As 15A NCAC 2H .0219(1) provides no'guideline for determination of flows from a
municipal water treatment facility, an evaluation of the treatment process was used
to determine flows. The wastewater flowing to the lagoons will include filter
backwashing water, sedimentation basin draw -off, intake sluicing water, and
treatment basin drains. The flows for each were determined as follows:
■ Backwashing water: Each of the three filters will be backwashed once every
72 hours using a total of 58,000 gallons per backwash. This will generate an
average of 58,000 gallons per day (gpd), of wastewater which will flow to the
lagoons. Each backwash cycle will also include approximately 24,000 gallons
of water which will be filtered to waste and discharged to the lagoons.
Maximum flow would occur if high volume backwashing of each filter was
carried out in one day, generating nearly 300,000 gpd.-
Sedimentation basin draw -off: The design capacity of the treatment facilities
is 5 -million gallons per day (mgd), but in the future the State may approve
higher flows through the plant so that the capacity will increase to 7.5 mgd.
A maximum of 0.5% of the plant flow will be diverted to the lagoons as
sludge fr6m'the sedimentation basins. Using the possible future maximum
plant flow (7.5 mgd), this process would contribute approximately 38,000 gpd
to the lagoons.

Page 3
■ Intake sluicing water: The river intake will be cleaned approximately once
every 6 months., The cleaning procedure will involve sluicing out the intake
with a 5 mgd flow for up .to one hour. This will generate approximately
210,000 gallons of wastewater each time the intake is cleaned. This will
result in an average flow of 1,140 gpd-and a maximum flow of 210,000 gpd
allowing for drainage of this flow in one. day.
■ Treatment basin drainage: The treatment basins will be drained
approximately once every 6 months and need not be concurrent with intake
sluicing. The average drain flow will be less than 1,000 gpd.
The total flow of wastewater to the sludge lagoons will average 100,000 gpd. The
lagoons will be lined with an impermeable liner such that no significant amount of
water -will be lost through seepage. Assuming no water is lost through evaporation,
the flow that will be discharged to the French Broad will be typically approximately
100,000 gpd with peaks up to 550,000 gpd. The three lagoons will provide a total of
2,244,000 gallons of storage which will allow an average of 22 days settling before
discharge to the French Broad River.
Facility Design
The facility design includes three rectangular sludge lagoons, each 100 feet by 200
feet in plan with 5 feet of depth and 1 1 /2 feet of freeboard. The intake and outfall
structure are located in opposite corners providing diagonal flow which will prevent
short circuiting. The lagoons will be lined with a High Density Polyethylene
(HDPE) material which will prevent seepage. A concrete liner will be included as a
bid alternate in lieu of the HDPE liner. The outfall structure will include a weir to
assure that the decant is drawn from the water surface.
The decant will flow by gravity from the lagoon through approximately 4,750 feet of
12-inch diameter polyvinyl chloride (PVC) pipe to the French Broad River. The
profile of the 12-inch diameter decant line (identified as "LD" on the drawings) is
shown on Sheets C-19, Cr20, and C-21.
As shown on Sheet CD-9�, the waste backwash water (24-inch diameter WBW), filter
to waste water (18-inch diameter FTW), and sedimentation basin draw -off (12-inch
diameter sed basin drain) tie into a 30-inch diameter WBW/FTW pipe which
discharges into the lagoons. The intake sluicing water (20-inch diameter WSW) also
ties into the 30-inch diameter WBW/FTW pipe, but can alternatively discharge
directly into Sludge Lagoon No. 2. The treatment basin drains for the ozone and
settled water channel (6-inch diameter D-DI) ties into the 24-inch diameter overflow
line (OVF) which discharges into the 30-inch WBW/FTW pipe. The 12-inch
diameter pipe used for the sedimentation basin draw -off and is also used to drain
the sedimentation basins and is routed to the WBW/FTW pipe.
