Discrimination Prohibited on the Basis of Handicap.
Attached is one (1) copy of the Project Review and Cost Summary (Authority to Award)
which is to be completed within 21 days after bids have been received, and submitted to the State
for review. Upon review and approval of this information, the State will authorize the Recipient
to make the proposed award.
Do not proceed with construction until the Authorization -to -Award package and the EEO
and MBE documentation/certification have been reviewed, and you are in receipt of our
approval, if a Federal loan is desired for project construction.
Two (2) copies of any change order must be promptly submitted by the Recipient to the
State. If additional information is requested by the State, a response is required within two (2)
weeks, or the change order will be returned without further or final action.
One (1) set of the final approved plans and specifications will be forwarded to you. One
(1) set of plans and specifications identical to the approved set must be available at the project
site at all times.
Upon completion of the project construction, the Recipient shall submit a letter confirming

LOAN SECTION
Enclosed are revised pages for the referenced report in accordance with your comments of June 18, 1997. Following
are itemized responses:
Although the existing 30 hp blowers are nearly adequate for aeration and mixing, the ORC informs me that
the motors are already having significant problems. Therefore, the existing blowers shall be abandonded
and three new 40 hp blowers shall be used to provide air to both the old and new plants (one for each side
with one back-up). This applies to all sub -alternatives under No. 5 except No. 5B in which the existing
blowers will be sufficient for 0.200 MGD. Blower curves are included in Appendix E.
2. More detailed breakdown of costs have been included for all sub -alternatives of Alternate No. 5. Most
costs are based on a schedule of values for a recent WWTP expansion of similar size. The contractor for
that expansion has indicated to me that current subcontractor prices are significantly up from a year ago
(such as concrete forming).
Based on the construction of Boiling Spring's existing facility in 1987, rock is assumed to be encountered
at about 6 feet deep for all proposed structures. Please note that concrete unit costs for circular clarifiers
are higher than for rectangular basins due to more complicated forming and rebar work.
Only one RAS pump station is included in 5C and 5D although this will create more operator difficulty.
3. Cost breakdowns have been provided. The calculations in Appendix E, part I and III, show the aeration
and horsepower requirements for the old and new plants. Blower curves have been added.
4. Alternatives 5B, 5C, and 5D have higher energy demand, therefore, requiring 125 kW generator in lieu of
100 kW.
5. The cost breakdowns now show these differences.
6. A new diffuser system in the existing plant has been deleted from all alternatives (except for replacement
of the diffusers only).
7. _ Same response as for Item 6.

• A. SUMMARY/CONCLUSION
The original 201 plan for Greater Cleveland County which was submitted by I W.
Pease Associates, in 1976 included the Town of Boiling Springs. A subsequent update of
the Boiling Springs portion of this plan was submitted in February, 1986, by West and Avery
Associates, P.A.
The 1986 update was for the purpose of upgrading the Boiling Springs wastewater
treatment facilities. The 1986 update resulted in the abandonment of two existing
wastewater treatment plants and the construction of a new facility at the site of the
abandoned Westside plant. A pumping station was constructed at the site of the abandoned
Eastside Plant which pumps wastewater into the gravity lines flowing to the new treatment
facility.
The new treatment facility constructed was a 300,000 GPD Aero-Mod package plant.
The flow into the Boiling Springs plant has increased to the point that the Town of Boiling
Springs must now expand the existing plant to accommodate the increased flow. As part of
this update, we evaluated the existing facilities and considered alternatives available to the
Town of Boiling Springs.
Based on our evaluation of each option available to the Town, we have concluded
that the most cost effective solution is to upgrade and expand the existing plant which would
be accomplished either by the addition of a new 0.300 MGD package plant (alternative #5E)
or by modifications and additions to obtain a conventional plant (alternative #5D), these two
alternatives having the lowest present worth costs for their respective types. The two
• alternatives should be designed and bid together.

Total: 191 inch -miles of gravity system
The wastewater collection system is comprised of
approximately 107,000 LF of 8" and 12" clay pipe and
approximately 11,000 LF of 8",12", and 15" PVC and ductile
iron pipe. Figure 1 illustrates the existing sanitary sewer
system for the Town of Boiling Springs. The majority of the
sewer system was constructed between 1965 and 1967. The
older and original collection system, located within the
campus of Gardner -Webb University was constructed by the
WPA in 1932. Much of the original system has been replaced
in recent years due to excessive inflow.
b. Pumping Stations
The Town of Boiling Springs operates four pumping stations
as part of the collection system.
Lyman Street Pump Station: The Lyman Street Pump
Station is located on the site of the original Eastside
Wastewater Treatment Plant which was abandoned in 1987.
The pump station is the largest station in the system and
serves the majority of the eastern Boiling Springs. The
Lyman Street Pump Station was constructed in 1988 and has
two 30 BP, 240 gpm Fairbanks Morse pumps. Culligen
Operation Services has conducted major maintenance on this
station in the past year. One power outage in excess of 30
minutes has occurred within the past 5 years. (See the
summary in the Appendix from Duke Power Company).

Phillips Village_Pump Station: Phillips Village Pump
Station is located off Patrick Avenue in the southern part of
the Town. This pump station serves approximately 25 homes
in Phillips Village. Phillips Village Pump Station which was
constructed in 1988 has two 10 HP, 150 gpm Flygt
submersible pumps. This station was completely upgraded in
1991. It has had two power outages exceeding 30 minutes
within the past 5 years.
Dellwood Drive Pump Station: Dellwood Drive Pump
Station serves northeast Boiling Springs. The Dellwood
Drive Pump Station is a Cantex unit with two 15 HP, 240
gpm Crane Denning pumps. This station was completely
rebuilt in 1994. It has had two power outages exceeding 30
minutes within the past 5 years.
Ramsgate Drive Pump Station: Ramsgate Drive Pump
Station is located off North Main Street near the Town
Limits. This pump station constructed in 1989 serves
approximately 30 homes. This station is in good condition.
It contains two 4 HP, 63 gpm Piranha grinder pumps. It has
experienced 5 power outages in excess of 30 minutes within
the past 5 years.
C. Overflows/Bypasses
During 1996 and 1997 to date, Culligen Operating Services
has noted two overflows at Dellwood Pump Station and three
overflows at Lyman Pump Station. The overflows at Lyman
Street Pump Station occurred as a result of high inflows
exceeding pump capacity. The Dellwood overflows occurred
as a result of a failed bubbler control system which has been
repaired. No records of any other overflows have been noted
by Culligen.
There have been no bypasses of any pump stations or
treatment plant.
d. Unserved Areas within the Town Limit
The majority of the developed area within the Town limits
has sewer available. The High Point area and Homestead
area in the northern part of the town are unserved and the
Highland Pines Acres area in the southern part of the City is
not served with sewer.

•
2. Treatment System Description
The existing treatment system consists of a manual bar screen, manual grit chamber,
and an Aero-Mod treatment plant which is an extended aeration, activated -sludge,
secondary plant The plant includes aeration basins, clarifiers, chlorination chamber,
and sludge digesters. All liquid and sludge flow are accomplished by gravity or air
lifts. The plant currently discharges effluent to Sandy Run Creek under NPDES
Permit No. NC 0071943, which has a flow limitation of 0.300 MGD (see copy in
Appendix). The existing plant was constructed in 1988. It is operated by Culligen
Operating Services under contract with the Town of Boiling Springs and has
achieved good performance except during hydraulic overloads of the clarifiers The
treatment units are as follows:
Manual Bar Screen: (1) 3'0" x 10'0" with 7/8" openings
Manual Grit Chamber: (1) 31x10' x 6'± with baffle
Aeration Basins: (2) 0.150 million gallons each with fine
bubble diffusers
Clarifiers: (6) 39" x 20'0" each, tube settler type
Blowers: (2) 30 hp centrifugal, 1200 CFM each
Chlorine Contact Basins: (2) 4'0"xl6'6"xT3" = 34 min. detention
Digesters: (2) 2l'xl6.5'x8.6' with coarse bubble diffusers
Flow Measurement: (1) 90-degree v-notch weir with float
indicator
The existing plant is usually able to comply with the NPDES limitations if the
hydraulic load does not exceed a certain threshold. The clarifiers are the most
limiting element because at much over the design flow of 0.300 MGD they
experience an overflow rate at which significant amounts of solids are allowed to
pass in the effluent. Currently, polymer is being added which enables compliance
with NPDES at about 0.300 actual flow, but any spikes in the instantaneous flow
tend to wash solids out of the clarifiers, such as during excessive I/I events. (See the
most recent effluent monitoring reports in the appendix). According to Aero-Mod,
Inc., (see letter in Appendix), an average overflow rate of about 600 gpd/sf should
be limited to the clarifiers in order to comply with the Permit if no polymer is added
to the influent The original design overflow rate of 769 gpd/sf requires polymer to
enhance settleability. So, in both the liquid and sludge trains, the clarifiers are the
limiting component because the effluent carries too much TSS and BOD thus
violating the Permit and reducing the return activated sludge amount such that a high
enough MESS concentration cannot be maintained in the aeration basins. However,
whenever the flow is within the limitation of the clarifiers, the plant produces a
quality effluent, therefore the other components are adequate except that some
maintenance and replacement is needed. The fine bubble diffusers have torn and
need replacing. Presently, 2.0 mg/E of dissolved oxygen cannot be achieved in the
aeration basins. The diffusers in the digesters are PVC pipes with drilled holes

which need to be replaced with standard coarse bubble diffusers in order to achieve
better mixing. The skimmers for scum removal are ineffective and need to be
replaced with improved types. In addition, it is assumed that submerged painted
steel parts probably need cleaning and painting to preserve their life. The manual
bar rack openings are too large, allowing plastics and other trash to pass through, and
therefore additional bars should be added or a mechanical screening device. Finally,
the existing blowers are barely adequate and should be replaced with 40 hp blowers.
Treatment and disposal of sludge consists of aerobic digestion followed by land
application by injection. The land used is a field owned by the Town and permitted
under WQ 0006827. Deficiencies of the system are (1), the sludge residence time
is theoretically only about 20 days (although it has been much longer due to solids
being wasted through the effluent rather than to the digesters), and (2), some of the
groundwater wells at the application site have contaminations, evidently from pre-
existing conditions. EPA Part 503 regulations require 40 days residence time at 20'
C to 60 days at 15° C in order to significantly reduce pathogens (PSRP) prior to land
application. Twenty (20) days at 10°C to 20' C may be adequate as a PSRP but is
unconservative and would require 7 fecal coliform laboratory tests per application
to comply with the 503 regulations. Therefore, additional sludge digester volume
is needed if land application is to continue and sludge wasting is to be increased to
desired levels. However, the problem of contaminated wells at the application site
would still exist, which makes compliance with the application permit difficult, and
therefore a new treatment/disposal system seems to be needed.
A Special Order by Consent (SOC) is currently proposed for the existing WWTP due
to its inability to consistently meet the permit limits primarily due to I/I. A copy is
included in the Appendix. As part of the SOC, the existing plant is to be expanded
in order to comply with NPDES limitations. A plan approval and construction
schedule is included under part 3(b). The first item has been completed. The next
three items are proposed to be changed as follows:
2) Begin construction April 30, 1998
3) Complete construction and I/I work January 1, 1999
4) Attain compliance with final effluent limitations April 1, 1999

At the present time approximately 2,400 people within the town limits are being
served with sewer. The areas which are not served were voluntary annexations with
an agreement that sewer would not be provided at the present time. There are
presently 807 sewer customers according to the Town's records as of March 18,
1997. 235 existing houses within the Town are not being served, thus, the current
service population is estimated as 3,005 - 235 x 2.5 = 2,418.
4. Infiltrationllnflow
During the past year, West and Associates, P.A., conducted smoke testing for the
Town of Boiling Springs. Several problem areas were identified and corrections
were made. Most of the problems were within the campus of Gardner -Webb
University. The Town currently has a contract let to replace 978 LF of sewer line
and 695 LF of storm drainage pipe located on the University campus. This project,
which will be completed by March, 1997, will eliminate a significant portion of the
remaining inflow.
a. Inflow
Inflow is estimated as the difference between expected flow and actual flow
for the peak following a 1" rainfall event preceded by 5 dry days. During the
month of October, Boiling Springs had a 1" rain on October 9th and a . 9 " rain
on October loth. The expected flow during October is the water
consumption less 10% for that month:

the inflow would be considered non -excessive.

• C. FUTURE SITUATION
Population
Currently the growth rate of Boiling Springs is exceeding that of Cleveland County
as a whole. In.1990 the Town's population was 2,445. In 1996 the population was
3,000. This represents a growth rate of 3.5% per year. The County's growth rate for
the period 1990 to 1995 was 1.01% per year.
A letter from the Cleveland County Building Inspector in the Appendix is further
evidence that the growth of Boiling Springs is well above that of the County. During
the last 3 years, new home construction in the Town comprised 14% to 2 1 % of all
homes started in the County, whereas the Town's population is only about 3% of the
County's.
Future growth of the Town's population is expected to continue at current or higher
rates, at least during the next 10 years, as evidenced by specific subdivision plans
and Gardner -Webb University plans.
Following is a description of these plans:
a. A letter from Gardner -Webb University states that the University has grown
at a rate of 10% per year for the past three years and anticipate this growth
rate to continue for the next several years. Based on discussions with the
University officials, it is very realistic to expect this growth rate to continue
for the next several years. In order to accommodate the additional student
population, the University is now constructing three dormitory style
apartments which will accommodate 144 new students. Other units are
scheduled to be constructed as the University population grows. To provide
housing for the increase in staff, the University is developing a 10 lot
subdivision for 3 and 4 bedroom homes.
During the next five years, the University expects the student population to
increase by 400 and staff and family by 30.
Population increase by 2001 due to University: 430
b. The Woodcreek Apartments for the elderly is beginning construction in
April, 1997 on 24 additional apartment units.
Population increase: 24
C. The Kee Subdivision is a new single family subdivision which has 30 lots for
3 and 4 bedroom homes. The developer expects to build these houses within
four years.

•
Population Increase: 30 x 3 = 90
d. In addition to the new development previously mentioned, there are seven
existing subdivisions within the town limits which are not presently
connected to the sewer system. Boiling Springs subdivision records indicate
that there are 235 existing homes not on sewer and 383 lots to be developed
which will be added to the sewer system. Developers expect to have these
subdivisions completely built out within 5 to 7 years and by that time, the
Town expects to have these subdivisions on the sewer system.

• D. ALTERNATIVES ANALYSIS
The following alternatives are considered for treatment and disposal of the Town's 20-year
design flow of 0.600 mgd.
Spray Irri ag tion
This alternative would involve the purchase of a large tract of undeveloped land on
which wastewater would be applied for slow rate infiltration and evapotranspiration.
If a suitable site could be obtainednear the WWTP, then the WWTP could be
modified for pretreatment. Using an assumed application rate of 0.20 gpd/sf, 69
acres would be required not including buffers. Therefore, an 80-85 acre tract would
be needed. A detention pond or lagoon would be required for periods of wet weather
and to allow for resting time for the land. A lift station would most likely be needed
to transport the WWTP effluent to the lagoon and then another pumping station to
pressurize the irrigation lines. Other costs would include sprinkler heads, standby
diesel generator, monitoring wells, and perimeter fencing to prevent public access.
In terms of environmental benefit, it may or may not be preferred to discharge to
surface waters depending on the assessment of impact on groundwaters and their
classification.
This alternative would not create open space or recreational areas for use by the
public because the effluent quality would not be high enough for human contact.
The costs for start-up services and operation and maintenance manuals are included
in the lump sum costs for all equipment (such as lift stations).
Costs are as follows:

• 2. Subsurface Disposal
This alternative would also involve the purchase of a large tract or tracts of land on
which wastewater would be discharged below grade for absorption and nitrification.
Pretreatment could be provided by the existing wastewater plant. For an assumed
application rate of 0.30 gpd/sf, and for 100% repair area, 92 acres of actual trench
area would be required for a 0.600 MGD application. For three-foot wide trenches
nine feet on centers plus unusable space and buffers would mean that approximately
300 acres would be needed. One or more lift stations and pump stations would be
required in order to lift the wastewater to various fields and then to pressurize the
lines.
Again, depending on assessment of impact on groundwaters, this alternative may or
may not have a less significant impact on the environment than discharge to surface
waters. Also, it is doubtful that a suitable site of this size could be found.
The costs for start-up services and operation and maintenance manuals are included
in the lump sum costs for all equipment (such as lift stations).
This alternative would create much open space for public recreation.
Estimated cost:
Land 300 AC @ $5,000.00/AC $1,500,000.00

Engineering (10%) 420,500.00
Contingencies and Administration (10%) 420,500.00
Total $5,046,000.00
2. Transport Wastewater to City of Shelby
This alternative would be to pump the Town's wastewater to the City of Shelby's
WWTP for treatment and disposal. Shelby also discharges to surface waters,
therefore, this option does not represent a reduced environmental impact unless
discharge to Sandy Run Creek was determined to be worse than discharge to the First
Broad River.
• This alternative would not create any open space or recreational areas.

The costs for start-up services and operation and maintenance manuals are included
in the lump sum costs for all equipment (such as lift stations).
Estimated cost:
12" Force Main 50,000 LF @ $25.00/L.F $1,250,000.00
Pumping Station Lump Sum 100,000.00

Engineering (10%) 190,000.00
Contingencies and Administration (10%) 190,000.00
Total $2,280,000.00
4. Take No Action
To take no action would be a violation of 15A NCAC 2H.0223(2) since current
annual average flow is in excess of 90% of the permit limit. In addition, flows are
expected to increasingly exceed the permit limit as time goes on, thus potentially
costing $25,000.00 per day in violation fees. At this rate, the cost of expansion to
0.600 MGD would be exceeded in 45 days. This is not a viable option.
5. Expand Existing WWTP
This alternative, which includes four sub -alternatives, would involve obtaining a
modified NPDES permit for a discharge of 0.600 MGD to Sandy Run Creek using
the existing outfall. The existing facility would then be expanded to treat the
wastewater to limits set by the modified NPDES. The existing facility is an
extended aeration, activated sludge, secondary plant manufactured by Aero-Mod,
Inc. Pretreatment consists of a manual bar screen and grit chamber. Disinfection is
achieved by chlorination. It is proposed to parallel the existing Aero-Mod plant with
a new similar plant, thus providing duality and double capacity. In addition,
pretreatment units would be replaced or modified and a standby power source
provided. Disinfection would be provided by an ultraviolet system in order to
comply with the probable residual chlorine limitations of the modified permit. A
pilot test for LIV disinfection has been performed which shows the method is
effective on the Town's wastewater. The new UV system would receive effluent
from both plants, and thus the existing chlorine system would be abandoned.
The new plant parallel with the old one would not have tube -settler -type clarifiers
as in the old plant due to the problems associated with those. The new clarifiers
would be external conventional or external Aero-Mod C1arAtor type or equal. It is
proposed that the old plant will be continued at a capacity of 0.300 or 0.200 MGD

• while the new one is designed for 0.300 or 0.400 MGD. Flow splitting would be
accomplished by weirs, orifices, and adjustable slide gates for infinite control by the
operator in conjunction with two separate flow measurement devices at the effluent
of each plant. The existing flow measurement is by a 90-degree v-notch weir with
a capacity of 0.700 mgd. The new plant would have the same type measurement.
The two measurements would be added together to give the total flow.
Separate flow equalization is not proposed since the 4-hour normal diurnal peak flow
is only about 1.3 times the average daily flow and the existing and new plants could
receive this daily peak without overloading the clarifiers However, due to the
sensitivity of the existing clarifiers, it is proposed to use the weirs and orifices at the
flow sputter box to limit flow to the old plant to about 0.300 MGD even during peak
flows. This will allow the new external clarifiers to receive most of the excess flow,
for which they are better suited to handle. (A sustained peaking factor of 2.0 for
storm events is used for sizing components).
Under this alternative, it is proposed that sludge treatment and disposal will use the
same method as currently except that the holding volume will be increased and that
the disposal would be to the City of Shelby's composting facility rather than the
Town's land application field. (See documentation in Appendix C regarding
Shelby's acceptance of this proposal and the sludge disposal alternatives analysis is
in Appendix G). The method of sludge treatment would be aerobic digestion, for
both the old and new plants. However, the primary purpose of the aerobic digesters
will be for sludge holding since the sludge would be introduced into the waste
activated sludge (WAS) pump station at Shelby's WWTP thus beginning the process
to significantly reduce pathogens (PSRP) after it was hauled. Therefore, the
digesters for the expanded facility would not need 40 to 60 days of sludge storage,
but rather a 30 day minimum. Air for mixing and volatile solids reduction would
be supplied to the digesters using the same blowers used for the aeration basins.
Thickening in all of the digesters would be achieved by supernatant being pushed
back into the aeration basins as mixed liquor is wasted from the basins.
Transportation of all sludge would be with the Town's existing sludge hauling truck.
A drain pipe would need to be installed at Shelby's WWTP which empties into the
WAS pump station in order to receive the sludge from the truck. Compliance with
40 CFR 503 regulations with regard to pathogen and vector attraction reduction
would be made by the City of Shelby as part of the permitted composting process.
The existing plant needs some repair work. This would include replacing the air
diffusers, cleaning and painting submerged steel parts (and replacing the scum
skimmers if the clarifiers continue to be used). In addition, effluent piping will need
to be modified.
The potential for open space under this alternative is small due to the small size of
the site. However, the northwest corner of the property is used and could continue
to be used for target practice.

® The estimated cost for this alternative is as follows:
Sub -alternative #5A:
Continue to operate existing plant up to 0.300 mgd average flow and 0.320 mgd
maximum peak flow. Use polymer to enable existing plant to achieve effluent
limitation of 30 mg/l BODS and 30 mg/1 TSS at flow range of 0.240 to 0.300 MGD.
Build new 0.300 mgd package plant with Aero-Mod-C1arAtor-type clarifiers

0 Sub -alternative #5C:
Convert existing wastewater plant to a conventional plant with an external circular
clarifier, designed for 0.300 mgd. Build new 0.300 mgd plant using conventional
design including an external circular clarifier. Clarifiers will be sized for 300 to 400
gpd/sf average overflow rate. Aeration basins will be rectangular concrete with
fixed -in -place diffuser system. Sludge digesters will be adjacent to aeration basins
so that supernatant is returned into mixed liquor by simple displacement method
(same as the Aero-Mod design). RAS and scum pumping stations will be required
for the clarifiers.

• Sub -alternative #5D:
Same as #5C except that the digesters would have decant pipes emptying into a
supernatant pump station which would return the supernatant to the head of the
plant. It is assumed that this method would achieve an average solids content in
sludge wasted from the digesters of 2.0%. Therefore, the digester size for each side
of the plant would need to be 64,500 gallons for 30-days storage instead of 86,000
gallons as under the previous sub -alternatives.

• Sub -alternative #5E:
Continue to operate existing plant, up to 0.300 mgd average flow and 0.320 mgd
maximum peak flow. Use polymer to enable existing plant to achieve effluent
limitation of 30 mg/1 BOD5 and 30 mg/1 TSS at flow range of 0.240 to 0.300 MGD.
Build new 0.300 mgd package plant with Aero-Mod-C1arAtor-type clarifiers
designed for 313 gpd/sf average and 939 gpd/sf peak overflow rates. Use
supernatant pump station to further concentrate digester sludge to 2.0% solids, as for

H. ENVIRONMENTAL ASSESSMENT
1. Existing Development
The area to be developed is located on the site of the existing wastewater treatment
plant. The new construction will disturb approximately .5 acre of the 4 acre site
owned by the Town of Boiling Springs. The property slopes from a high elevation
of 725 at the southeast corner to a low elevation of 688 along the western property
line. The western property line generally follows Sandy Run Creek.
There is an existing 300,000 gallons per day wastewater treatment plant on the site.
This plant was constructed in 1988 with the knowledge that a future expansion
would be necessary. The original site plan made provisions for a future expansion
of the plant. The area reserved for the plant expansion was rough graded and
grassed.
2. Existing Environment
Boiling Springs is located in the southeastern quadrant of Cleveland County. The
topography of the Boiling Springs area and the remainder of Cleveland County
consists of a series of rounded hills and rolling ridges with a general southerly trend.
The surface has a gentle, southeastward slope with an elevation of about 1600 feet
in the northern part of the county and dropping to about 600 feet in the southern part.
Interstream areas are generally broad and have a gently -undulating surface with
moderate relief. However, streams have incised the valleys through which they flow
until they are usually more than 100 feet below the general level of the interstream
areas. Thus, the resulting topography is characterized largely by low, generally
rounded hills with gently to moderately steep slopes.
There are prominent peaks, or monadnocks, that rise several hundred feet above the
upland surface. Most of these peaks are composed of rocks more resistant to erosion
than those of the surrounding peneplain. In the northern part of the county these
peaks, Carpenter Knob, No Business Mountain, and others, are underlain by massive,
poorly fractured quartz-biotite gneiss. The highest elevation of the county is in the
northwest corner where Benn Knob rises to an elevation of 2,894 feet.
In the southeastern corner of the county, beds of quartzite and quartz conglomerate
form the Kings Mountain Range. The range itself, extends from South Carolina in
the south across Cleveland, Gaston, and Lincoln Counties and into Catawba County
in North Carolina.

•
3. Surface Geology
As illustrated in Figure C-1, there are four lithological units within Cleveland
County: the Cher yville quartz monzonite, the Tuluca quartz monzonite, the Kings
Mountain group, and the mica schist -gneiss complex. Outcropping in irregular and
complex patterns the mica schist and gneiss complex is the most widespread of these
four units and probably underlies as much as 75 percent of the total land area in
Cleveland County. The Boiling Springs vicinity is characterized by this mica schist
and gneiss complex.
The mica schist and gneiss complex represent metamorphosed sedimentary and
pyroclastic volcanic rocks generally regarded as late Precambrian or early Paleozoic
in age. These rocks consist of an immense series of mica schist, mica gneiss, and
granitoid layers, in which mica schist usually predominates. Locally, however, more
gneissic rocks may predominate. The gneissic rocks are light to dark gray, and
weather to dull gray, yellow and various shades of red. Bands and lenses of mica
gneiss, composed of quartz, feldspar, with biotite and muscovite in varying amounts,
with the biotite predominant at most localities, are also common in the unit. Also
occurring in many places are thin, interbedded layers of homblende gneiss and
schist. Included in the complex are decidedly younger bodies of quartz monzonite,
gabbro, and dikes and lenses of pegmatite.
The mica schist and gneiss complex is deeply weathered at most areas and is covered
by a thick layer of residual clay containing fragments and layers of the parent
material. The soil cover overlying the thick residual clay and weather rock is usually
light and thin.
The mica gneiss -schist group is the main producer of ground and scrap mica and
good quality sheet mica comes from pegmatitic quarries operating in Cleveland
County. Stone, clays, and sand and gravel are mined in several localities of this
group. Limestone is mined for cement manufacturing in the county, clay is produced
from shales, metashales, slates, and weather rocks, and sand and gravel come from
alluvial deposits.
The soil type on the site of the WWTP is Pacolet-Saw complex according to the
USDA Natural Resources Conservation Service. A description provided by the
USDA is as follows:
Pacolet-Saw complex, 15 to 30 percent slopes stony. This map unit
• consists of moderately steep Pacolet soils and Saw soils on uplands.
Pacolet soils are very deep and well drained. They have a loamy
surface layer with a significant amount of gravel and a clayey subsoil.
Numerous stones are scattered over the surface. Permeability is
moderate and shrink -swell is low. Seasonal high water table is below

•
6.0 feet. Saw soils are moderately deep and well drained. They have
a loamy surface layer with a significant amount of gravel and a
clayey subsoil. Numerous stones are scattered over the surface.
Permeability is moderate and shrink -swell potential is low. Hard
bedrock is within a depth of 20 to 40 inches. Seasonal high water
table is below 6.0 feet.
4. Water Resources
As shown in Figure D-1, Cleveland County is drained by the Broad River and four
of its major tributaries: The Sandy Creek, First Broad River, Buffalo Creek, and
Kings Creek. Boiling Springs lies in the Sandy Run Creek Basin. The river is
approximately 15 miles in length and has its headwaters on the south eastern slope
of the South Mountains near the Rutherford County line. Sandy Run Creek is
classified as a Class C stream with a seven year low flow of 1.44 MGD.
5. Ground Water Supply
Ground water is an important resource of Cleveland County. Much of Cleveland
County is dependent upon subsurface sources of water supplies. Smaller towns,
individual residences, and industries are characteristically served by a single well.
Still, ground -water resources of the County have been developed only to a very
limited extent. It has been estimated that the average annual county use of 3 billion
gallons is less than 7 percent of the assumed total recharge.
Ground -water supplies of at least a few thousand gallons per day are adequate for
domestic and similar purposes and can be obtained almost anywhere in the area from
individual wells tapping the bedrock aquifers. The average well will yield about
1800 GPD.
Moderate to large supplies of ground water --sufficient for most industrial,
commercial, and municipal uses --can be obtained from most of the geologic
formations of Cleveland County.
Differences in well -yields are usually a function of variation in weathering or
fracturing. Each rock unit normally has distinctive fracturing and weathering
characteristics and thus indirectly influences well yields. There are three major rock
types in the lithological unit most common in Cleveland County: (1) schist, (2)
gneiss, and (3) gneiss and schist. Schist is the predominate rock and has the largest
number of wells. Their average depth is about 190 feet ranging from 42 to 750 feet.
• Their yields vary from 0 to 150 gallons per minute (GPM), averaging about 25 GPM.
Wells drilled into gneiss have an average depth of 226 feet; range in depth from 61
to 1,213 feet; have a yield which ranges from 0 to 200 GPM; and have an average
yield of 35 GPM. Most drilled wells in gneiss and schist obtain adequate supplies
for domestic and farm use at depths ranging from 100 to 200 feet.

• 6. Need
The Town of Boiling Springs currently has a .3 MGD wastewater treatment plant.
The average daily flow into the plant for the month of September was 257,000
gallons per day or 85.67% of the plant capacity. Due to the heavy hydraulic loading
of the plant, there have been several times during the past year that the town has
failed to meet the NPDES limits. In order to address their wastewater treatment
needs, the town is to enter into an SOC which requires the town to have the plant
upgraded by October 1, 1998.
The need for a plant upgrade is justified by the hydraulic loading on the existing
plant and the fact that the town is under a Special Order by Consent.
7. Alternative Analysis
In addition to expanding and upgrading the existing plant, four alternatives were
considered. These alternatives were: spray irrigation, subsurface disposal, pumping
the wastewater generated in Boiling Springs to Shelby for treatment, and making no
change in the existing system.
After an evaluation of the options available to the town, it was determined that the
most cost effective and environmentally sound method of treating the wastewater
generated in Boiling Springs is to expand and upgrade the existing plant.
A more detailed evaluation of the alternatives are shown in a previous section of this
report.
8. Environmental Consequences
a. Changes in Land
The proposed plant expansion is to be located on a site which was developed
for this purpose in 1988. The only changes in the land will be some minor
grading to accommodate the new facilities. Approximately 0.5 acres of
natural area will be disturbed.
b. Wetlands
There are no wetlands located on the proposed site and the finished grade of
site is well above the floodplain level.
C. Prime or Unique Agicultural Lands
• There are no agricultural lands of any kind to be disturbed as a result of this
project.

0 k. Wildlife Habitat
The approximately .5 acre site to be disturbed as a result of this project is
immediately adjacent to an area which has been cleared for at least 30 years.
There are no wildlife habitats located on the site.
1. Toxic Substances
The Town of Boiling Springs has no industry discharging into the wastewater
system and as a result there are no heavy metals or toxic substances
introduced from this source. Toxins introduced from domestic sources do
not create a toxicity problem in the plant effluent.
The effluent clarity of the plant is such that the use of ultraviolet disinfection
is being considered. If chlorine is used as disinfectant then we will
dechlorinate to prevent any toxicity problems.
M. Receiving Stream
The Boiling Springs Wastewater Treatment Plant discharges into Sandy Run
Creek a Class C stream in the Broad River Basin.
The Sandy Run Creek Basin is approximately 15 miles long and has its
headwaters in the southwestern portion of Cleveland County. There are no
impoundments on Sandy Run Creek and there is a steady flow of at averages
1.44 MGD. Current and future (speculative) effluent limitations will be 30
mg/1 BOD and 30 mg/l TSS for the plant effluent. Therefore, the maximum
pollutant loading to the stream at the 20-year design flow of 0.6 MGD would
be 0.6 X 30 X 8.34 =150 LB/DAY of BOD and 150 LB/DAY of TSS. NH3
N limits would be 15 mg/1 in the summer, therefore the pollutant loading
will be 75 LB/DAY of NH3-N.
n. Indirect Measures
The plant capacity will increase from .3 MGD to .6 MGD and the increased
flow in the future could possibly have some indirect impact on the receiving
stream, however, since the discharge is so small compared to the stream flow
and the quality of the plant effluent will improve, the impact should be
negligible.
9. Mitigative Measures
In order to avoid any adverse environmental impacts, the following actions were
• taken:
a. Proper.erosion control measures to reduce site siltation.

•
b. Use of ultraviolet disinfection to eliminate the use of chlorine is being
considered.
C. Improved treatment process will improve effluent discharged into Sandy Run
Creek.
"NOTE: Portions of environmental report are from a study by Dr. James W. Clay
for Cleveland County and Boiling Springs.
10. Summary/Conclusion
In conclusion, the cumulative and indirect environmental effects due to an expansion
of the WWTP would be:
a. Twice the current design flow would be discharged in 2016, but probably at
lower pollutant concentrations.
b. Chlorine would no longer be discharged to Sandy Run Creek.
C. Approximately 0.5 acres of natural area will be disturbed.
The negative effects (#1 and #3) are considered insignificant compared to the
potential effects of doing nothing and continuing to operate the WWTP beyond its
design capacity.

Subject: Boiling Springs Wastewater Treatment Plant Expansion
NPDES Permit No. NCO071943
Cleveland County
Dear Mr. Hamrick:
Your recent request for speculative effluent limits for the expansion of the Boiling
Springs WWTP from a design flow of 0.300 MGD to an expanded flow of 0.600 MGD
has been completed by the staff of the Technical Support Branch. In order to receive final
permit limits, a formal application will have to be submitted to the Division's Permits and
Engineering Unit. Per North Carolina's anti -degradation policy (15A NCAC 2B.0201
(c)(1)), each application for an NPDES permit or NPDES permit expansion to discharge
treated waste will require documentation of an effort to consider non -discharge alternatives
pursuant to North Carolina Regulation 15A NCAC 2H.0105 (c)(2).
Based on available information, the tentative limits at 0.600 MGD for conventional
constituents are:

*nr - no requirement
It should be noted that the summer NH3-N limit is based on protecting Sandy Run
Creek against instream toxicity. North Carolina is evaluating all NPDES dischargers for
ammonia toxicity following the Environmental Protection Agency (EPA) guidance to
protect the waters for an instream criteria of 1 mg/l in the summer and 1.8 mg/1 in the
winter, under 7Q10 flow conditions.
The Division of Environmental Management (DEM) is now recommending chlorine
limits and dechlorination for all new or expanding dischargers proposing the use of
chlorine for disinfection. An acceptable level of chlorine in your effluent is 28 4g/1 to
ensure protection against acute toxicity. The process of chlorination/dechlorination or an

alternate form of disinfection; such as ultraviolet radiation, should allow the facility to
comply with the total residual chlorine limit.
The request did not indicate whether any of the expansion wastewater would have
any industrial constituency, therefore this aspect could not be evaluated. If there is any
industrial flow, there is the possibility that effluent limitations or monitoring for toxicants
or metals could be added to the permit upon further evaluation.
DEM is implementing a basinwide water quality management initiative. Our
schedule for the Broad River Basin is set for 1998. The plan will.attempt to address all
sources of point and iiot►pUU.n poilutants wh cx deemed recess^y.to pro+mot or msrpm
water quality standards. In addressing interaction of sources, wasteload allocations may be
affected. Those facilities that already have committed to high levels of treatment technology
are least likely to be affected.
Final NPDES effluent limitations will be determined after a formal permit
application has been submitted to the Division. If there are any additional questions
concerning this matter, please feel free to contact Ruth Swanek (ext. 503) or Jackie Nowell
(ext. 512), of my staff at [phone].

Commission allows the Town to accept the additional waste
specified below to its waste disposal system:
200,000 gpd of additional wastewater. The nature of the
additional flows is such that the waste characteristics do not
exceed those generally associated with domestic waste or are
pretreated to domestic strengths. Waste of greater than
domestic strength may be accepted if the parameter(s) that
exceed normal domestic strength wastewater are not those for
which interim limitations have been developed and it can be
demonstrated to the satisfaction of the Director that the
additional waste will not adversely affect the treatment
efficiency of the treatment system for any modified parameter
or result in the violation of any other permit limitation.
All new and proposed industrial waste tributary to the system
must be controlled using all needed mechanisms including, but
not limited' to, adoption and implementation of industrial
waste control and pretreatment ordinances. No wastewater can
be accepted which will add toxic pollutants in quantities not
generally associated with domestic wastewater characteristics,
unless the acceptance of the additional wastewater can be
supported through appropriate analyses acceptable to the
Director.

• VIII. Fine Bubble vs. Coarse Bubble Diffused Air Comparison
A. Assumptions:
1. Installation cost is same for both options, therefore excluded.
2. Use new 0.300 mgd plant, conventional design, for purposes of this
comparison. Aeration basin and digester have 12-foot side water depth.
3. Digesters require coarse bubble diffusers for both scenarios.
4. Fine bubble system is all PVC construction, coarse bubble system is all
stainless steel construction.
5. Use 20-year net present worth (cost) basis with discount rate of 7.75%.
B. Fine Bubble Option:
1. Per Enviroquip International, Inc., 9" dia. Flexible membrane discs deliver
17.25% clean -water SOTE. 252 diffusers are required for a 80'x42x12' basin
to deliver 500 SCFM. The actual oxygen transfer efficiency (AOTE) for this
configuration would be 7.4%. Equipment costs are $10,500 for the aeration
basin and $2,900 for the digester. Per Invincible Blowers, Inc., a two -blower
package to deliver 850 SCFM at 6.1 psi would cost $20,846 using 40 BP
motors.
Total equipment cost = $10,500.00 + $2,900.00 + $20,846.00
_ $34,246.00
2. Membrane diffusers have 5-year life expectancy and require cleaning twice
per year. Replacement cost = $7/diffuser. Cleaning requiers draining basin
(which will require pumping), hosing off diffusers, and in some cases,
brushing each diffuser. Use $1,000.00 estimated cost per cleaning.
Annual Maintenance Cost = (252 x $7.00)/5 + 2 x $1,000.00 = $2,353.00
3. Annual Energy Cost:
The Town currently pays $0.0262/kwh average. (Actual rates vary
depending on time of day and time of year). 40 BP blower running 18
hr./day, 365 day/year uses 196,049 kwh/year.
Annual Energy Cost = 196,049 kwh x $0.0262/Kwh = $5,136.00
4. Salvage Value:
Since the system is all PVC, assume no salvage value at the end of 20 years.
The blower package would also have no salvage value.
0

5. Total Present Worth:
P.W. _ $34,246.00 + [ P/A, 7.75%,20]($2,353 + $5,136)
_ $34,246.00 + ($7,489)(10.004)
_ $109,166.00
C. Coarse Bubble Option:
Per Enviroquip International, Inc., 24" stainless steel wide band diffusers
would deliver 8.25% clean -water SOTE and 3.92% AOTE. 52 diffusers
would be required in the aeration basin to deliver 910 SUM. Equipment
costs are $12,700.00 for the aeration basin and $2,900.00 for the digester.
Per Invincible Blowers, Inc., a two -blower package to deliver 1260 SCFM at
6.1 psi would cost $26,266.00 using 50 BP motors.
Total Equipment Cost = $12,700.00 + $2,900.00 + $26,266.00
_ $412866.00
2. Coarse bubble diffusers would not require cleaning or replacing during the
20-year period.
Annual Maintenance Cost: $0.00
3. Annual Energy Cost:
50 BP x 0.746 kw/BP x 18 hrs/day x 365 day/year = 245,061 kwh/yr.
Cost = $0.0262/kwh x 245,061 kwh/yr.
_ $6,421.00
4. Salvage Value:
Assume the all stainless steel system would have a life expectancy of 40
years. Then salvage value in 20-years would be (1/2)($12,700 + $2,900) _
$7,800. The blower package would have no salvage value in 20 years.
5. Total Present Worth:
P.W. _ $41,866.00 + [P/A,7.75%,20] [$6,421] - [$7,800][P/F,7.75%,20]
_ $41,866,00 + ($6,421x10.004) - ($7,800x.2247)
_ $104,349

D. Conclusion:
Both options have very similar net present worth. The coarse bubble option,
however, is preferred since it has a slightly lower present worth cost and does not
have the likelihood of failing due to inadequate maintenance. Therefore, coarse
bubble, stainless steel diffusers and piping are proposed for any plant expansion or
retrofit.

A WATERLINK COMPANY
March 26,1997
To: Mr. Btnji Thomas
From: John McNellis
Re: Boiling Springs, NC WWTP
Dear W. Thomas:
As per our phone conversation concerning the referenced proiect, I offer the following-
1, The existing treatment plant has six (6) Model 2665 tube settler module/clarifiers. Each
module has 65 square feet of surface area. At a flow rats: entering the plant of 300,000 gpd,
each module will need to handle a flow rate of 50,000 gpd. The surface overflow rate (SOR) at
this influent flow rate is 769 gpd/sf. At the time this plant was installed, this was an allowed
overflow rate. Experience has shown this type of clarifier will often times require polymer to
aid in the settling of the solids at an SOR this high. Thus, in order for this plant to handle the
300,000 gpd flow rate, the operator will need to assist in the settling characteristics of the
biomass by adding polymer.
Should the surface overflow rate (SOR) exceed 800 gpd/sf or more, the ability of the modules
to perform well will decrease as the SOR increases. Therefore, when constructing the new
splitter.box, I recommend the flow rate entering the old plant be limited to a maximum flow
rate of around 315,000 to 320,000 gpd, thus giving the old plant a better chance to operate
well.
2. Concerning the plants ability to handle the organic load, the change of the diffusers to the
stainless steel coarse bubble diffusers should help. It is my understanding the diffusers
existing are just PVC pipe with drilled holes. If this is true, then the SS diffusers will improve
the transfer of oxygen to the system.
The following page shows our latest calculations for air. The Spencer blowers presently it the
plant are rated ate 12001CFM Iig 3.4 psig. They should be okay based upon the numbers I
show on the following page. 'If the strength of sewage entering the plant is greater than what
we based the design on (original BODITSS/ammonia was set at 240/240/15 mgA,
respectively), then the blowers may need to be changed. I do not have any data to confirm the
strength of sewage entering the plant. so unless the organic loading is greater than we based
our design on, I would not change the blowers.
If you have any questions, please call.
Sincere' ,

THE SPLIT-ClarAtor Th' CLARIFIER
The Standard in Clarifier Design
The Split-ClarAtor is the latest in AERO-MOD's ClarAtor clarifier technology. This secondary clarifier for biological wastewater treatment plants can be
used for a wide range of flows and is excellent for retrofitting rectangular clarifiers. It is the first clarifier to resolve classic problems circular clarifiers
have experienced. Best of all, the technology involves no moving parts in the clarifier and all fabrication is out of stainless steel. The result is
state-of-the-art technology, the new standard in clarifier design.
Briefly, the Split-ClarAtor addresses the following issues:
With Split-ClarAtor technology, the influentflows through aflocculation zone prior
to being distributed evenly across the bottom of the clarifier directly into the
settling zone. The result is a dissipation of energy and improved flocculation.
Once the influent has entered the settling zone, removal of solids is even, rapid,
and across the bottom of the clarifier. Stationary hydraulic suction hoods use air
lifts on 4' centers to rapidly remove the settled solids and thus eliminate sludge
stirring. The return activated sludge (RAS) is returned to the aeration tank via a
RAS trough into a bio-selector tank and into the aeration tank. Note mechanical
pumps are not needed.
The effluent is drawn off evenly across the
entire clarifier basin through submerged
launder weir pipes which discharge
through AERO-MOD'S patented flow
regulation system. This unique system
makes ClarAtor technology the only
clarifiers in the world able to regulate the
effluent flow rate on the downstream end
and absorb the excess flow within the
basins or unique side -line surge tanks. In
other words, regardless of the influent
flow rate to the plant, the effluent flow rate
r?mains fairly constant. Thus, solids
washout due to peak flows is minimized.
Because effluent is drawn -off evenly
and uniformly across the clarifier basin,
density currents or uneven velocities
are eliminated. The result is improved
effluent quality.
No field welding or painting is required
, •�
with Split-ClarAtor clarifiers. Access to
the clarifier is by walkways across the•
tops of the Split-ClarAtors. Depending,
on the length, several Split-ClarAtorsT
can be shipped per flat bed truck. Con-
crete construction must be done prior
to the equipment arriving on -site. Once
on -site, the hydraulic suction hoods are
placed on the floor of the basin, the
upper portions set in notches, and the air lift pipes connecting the two sections
are field installed.
Let AERO-MOD provide you with a detailed proposal specifically designed for your
needs. We believe you will see how simple it is to design around cost effective
AERO-MOD equipment. With ClarAtor technology, you can design a secondary
wastewater treatment plant that will operate for well beyond the "20 year expec-
tancy life" with practically no maintenance.

The Split-ClarAtor --A Description
The Split-ClarAtor can be installed as a single unit or in
multiple units into rectangular clarifier basins. They
come in various lengths. The basin is sized for the
square footage necessary to meet the design clarifier
overflow rates of the plant. The lower half of the
Split-ClarAtor assembly (hydraulic suction hood as-
sembly) is set into the bottom of the tank. Multiple
units are placed such that a space between the
suction hood assemblies is allowed, which are later
covered with the stainless steel distribution hoods.
The units are then bolted tothe floor.
Prefabricated stainless steel assemblies provide the
inlet feed and distribution means. These are fabri-
cated in assemblies which simply bolt to the wall or to
the lower half of the Split-ClarAtor. A "chimney" sec-
tion directs the outflow from the screen box down into
a "header' section. This "header' section is perpen-
dicular to, and sets on top of the ClarAtor bottoms.
This bolts to the wall and covers the annular space
between the end of the ClarAtor bottom and the wall.
This annular space allows the ClarAtor section to be
lowered into the tank and allows for variations in
contractor construction. The "header' section feeds
into longitudinal feed sections, i.e., "side distributors",
running the length of the ClarAtor. These sections are
also of stainless steel. The outer two sections of each
clarifier complex bolt to the wall with SS fasteners and
simply set on the top of the ClarAtor bottom section.
Ports are located on the bottom of these sections to
provide even distribution of the mixed liquor into the
settling zone. The "side distributors" sections be-
tween ClarAtor bottoms are pyramid shaped. Tabs
are provided for simple fastening to the lower sec-
tions. These also have ports for uniform feed to the
clarifier area. All fabricated sections are steeply
sloped to prevent accumulation of settled solids on
theirsurfaces.
The upper portion of the Split-ClarAtor is set into
notches in the concrete wall. Effluent pipes are con-
nected and air lift pipes connect the apex of the
suction hood to the bottom of the activated sludge
return trough (RAS trough) in the upper section.
The Split-ClarAtor is excellent for all types of biologi-
cal treatment. With the Split-ClarAtor, the aeration
tank is sized for the organic loading and the diffusers
installed to meetthe oxygen demand.
The following describes the features of the Split-Clar-
Ator. Note the reference numbers on the sections
refer to the same numbered areas on the attached
drawings
1. SCREENING
The mixed liquor suspended solids (MLSS) inletto the
Split-ClarAtor is screened with slotted stainless steel
panels. Screening prevents trash in the aeration tank
from entering the clarifier section. Regardless of the
degree of preliminary treatment, "ragging" and leaf
accumulation can still occur in aeration tanks. For
each Split-ClarAtor, a stainless steel box with screen
is provided. These are located on the aeration tank
side of the clarifier wall. Slot openings are typically
1 /2" by 24" long and are located 1 1 /2" on center. The
slotted screens bend out into the aeration tank, forc-
ing solids to be washed off the screen by the tur-
bulence of the aeration tank. The screen elevations
are designed such that at normal operational levels,
the screen is 75-80% submerged. This allows the
area behind the screen to be open to the aeration
tank. This prevents accumulation of grease and
floatables behind the screen. In the unlikely event the
screen does require cleaning, it is easily accessed
from the walkway immediately above and can be
brushed clean with a common push broom.
2. FLOCCULATION
It is desireable to allow a period of time for the
bacterial floc to reform or flocculate into larger and
better settling particles before it enters the clarifier.
This occurs within the screen box and the inlet feed
system. The flow is from the surface down. This
allows grease and air bubbles to escape back to the
aeration tank before entering the clarifier. Since the
flow is taken off near the surface, this screening and
flocculation box offers another advantage. In the
event the air supply to the plant fails, the MLSS within
the aeration tank will settle and the boxes will essen-
tially skim the clear supernatant off the top of the
aeration tanks. Thus, the clarifiers can continue to
function without solids overloading even though the
sludge return airlifts are not functional. The floccu-
lated waste exits the screen box through pipe inserts
in the wall. The box is sloped to the point where the
insert is located. This insert connects with the chim-
ney on the other side of the wall. Some optional
arrangements may consist of hard piping from the
box outlet tothe chimney inlet.
3. CHEMICAL FEED
Although chemical feeding is normally not required in
biological processes, there are times when it may be
desirable. This may include alum for phosphorus
removal, or polymers for increased settling. The

screening and flocculation box provides a convenient
point at which to add chemicals if required.
4. CLARIFIER INLET
The flocculated sludge enters the sedimentation zone
through the distribution channels and a series of
orifices which run the entire length of each Split-Clar-
Ator. Each Split-ClarAtor is fed from each side. If two
or more Split-ClarAtors are side by side, a single
longitudinal section between each unit will feed them
both. The headers and orifices are sized to handle the
maximum flow when the return air lifts are operating.
At this maximum flow the orifices are sized to provide
a head loss greater than the friction loss in the header
sections. The orifices are also widely separated to
prevent ragging from hole to hole. This design prin-
cipal is necessary to assure even distribution across
the clarifier. The orifices discharge downward into
the sludge zone. The orifices are also at the bottom of
each distribution device and the resultant high
velocity during sludge withdrawal operations
prevents solids accumulation.
An additional hydraulic principal helps assure even
distribution across the lower portion of the clarifier.
The effluent collection pipes at the surface contain
orifices that run the entire length of the Split-ClarAtor
and also create an even withdrawal across the sur-
face of the clarifier. This even withdrawal at the top
helps assure an even distribution at the bottom.
5. SEDIMENTATION ZONE.
As sludge enters above the sedimentation zone,
solids will settle into the area of the sludge suction
hood. This area is lined with smooth stainless steel
and sloped at 60 degrees. Every four feet reinforce-
ment fins are welded to the pan and serve to segment
the clarifier into four foot sections. The slope directs
the solidstothe mouth of the hydraulic suction hood.
The Split-ClarAtor is not designed to be a sludge
thickening device. The functions of sludge thicken-
ing, storage, and ultimately wasting are incompatible
with the functions of clarification. Instead, AERO-
MOD uses the direct wasting of mixed liquor to a
digester. With automatic wasting and decant, the
digester becomes an excellent thickener.
6. HYDRAULIC SUCTION HOOD.
The hydraulic suction hood runs the entire length of
each Split-ClarAtor and removes the sludge from the
bottom of the clarifier. Every four feet along the apex
of the sludge suction hood, 4" airlifts are installed to lift
the sludge up to a collection and discharge trough.
The suction hood is made up of two "inverted V"
structures that are placed one on top of the otherwith

a space of two inches between them. Divider plates
.are installed between these two structures at four foot
intervals, with the plate centered between each air lift.
Thus, each airlift will provide suction to only four feet
of suction hood. This assures that each airlift will only
pull sludge from its assigned area and that sludge
must pass through the designated collection ports.
The annular space between the two "V" structures is
limited to assure maximum upflow velocities during
sludge removal. The long "V" shape is not a hopper.
There are no corners or sidewall intersections to
retain solids. Bridging does not occur since
withdrawal is uniform along the entire length of the
"V". Like a wide vacuum cleaner,. each air lift suction
provides eight lineal feet of suction.
7. COLLECTION PORTS.
Collection ports are cut into the upper "V" structure of
the hydraulic suction hood. When this is welded to
the clarifier floor these ports become the only point at
which sludge can be removed. The ports are 2" by 2"
with a rounded top and are located 7-1/2" on center.
The wide spacing of the ports prevents strings and
rags from wrapping from hole to hole. Orifice sizes
and return air lift capacities assure scouring velocities
across the bottom of the ClarAtor and into the suction
hood of greater than 1 fps.
8. SLUDGE AIR LIFTS.
The airlifts are four inches in diameter, fabricated from
PVC, and fasten between the upper and lower sec-
tions of the Split-ClarAtor. A 1/2" air supply line is
tapped into the airlift section approximately 9' below
the water surface. Air for this line is supplied by a 2"
PVC air line which is factory installed within the
walkway support. The flow rate is regulated by a PVC
ball valve. The air lifts do not operate continuously. A
small 1 /2"diaphragm valve is provided for each air lift
and is located after the air control valve. This auto-
matic valve is a normally open valve and receives a
control signal via 1/4" pneumatic line from the Split-
ClarAtor control panel. Thus the valve is fail safe
"normal", meaning that in the event of a pneumatic
failure the sludge return will still operate.
The on -off functions are controlled by an interval
timer. By setting time on and time off, the rate of
return can be controlled and adjusted. Each air lift is
capable of drawing 200 gpm and will clean 32 square
feet of clarifier. At a clarifier overflow rate of 500 gpd/sf
(11.1 gpm), the airlift has a return rate capability of
1800%. If the operator sets the time at 3 minutes on
and 27 minutes off (10%) the actual sludge return rate
will be 180% of the design flow. Thus, the recycle rate
is easilyadjusted and controlled bythe operator.
9. SLUDGE RETURN TROUGH.
Each of the airlifts discharges into a common sludge
collection trough (RAS trough). The bottom of this
collection trough is above the normal clarifier water
surface. This return activated sludge is discharged
out the end opposite the effluent collection box and
can be discharged either to a pipe collection system,
the aeration tank, or to an open tank serving as a
selector or anoxic tank. The head available at this
point is sufficient to allow the return activated sludge
to flow through the plant piping and return to the
aeration tank with no additional pumps. The trough is
nearly 32 "wide by'8" deep and provides adequate
volume for simultaneous discharge of all airlifts. The
trough is immediately below the aluminum grate
walkway so the operator can visually observe the
return sludge and sample as required.

10.SKIMMERS
The skimmers are simply mini -air lifts taking suction
through a wedge shaped notch in a floating collar.
Flow rates are adjusted by a 1/2" ball valve. The
floating collar rides on the liquid surface and tele-
scopes into a receptacle so that the skimmers draw
no more during high flows than during low flows. This
helps prevent hydraulic overflow during surge condi-
tions. The skimmer is kept in position by a brass guide
rod through the floating collar. A manual suction
depth adjustment can be made by sliding an internal
sleeve up and down as desired: Each skimmer dis-
charges into the sludge return trough. Due to the
design of the screen box and the downward entrance
to the clarifier, most of the material that would require
skimming in a conventional clarifier has been
removed bythe ClarAtordesign.
11. EFFLUENT COLLECTION PIPE
Two triangular effluent collection pipes are provided
for each ClarAtor section. Each collection pipe is
submerged and contains 5/8" holes evenly spaced
along both of its top sides. Hole placement above the
bottom of the triangle prevents any rising solids such
as scum or grease from entering the collection pipe.
Instead, theyfloat up to the surface to be picked up by
the skimmers. The bottom of the triangle is sloped at
30 degrees to provide a better flow channel within the
triangle and to prevent any rising grease or scum from
accumulating under the triangle. The submergence
also helps to prevent ice plugging in cold climates.
The triangle shape also helps to prevent solids from
accumulating on the top of the pipe.
12 SURGE CONTROL
DEVICE
The AERO-MOD patented built in
surge control equipment is the
ideal solution for processing
moderate peak flows. Surge con-
trol (flow equalization) is ac-
complished by a 3-weir device and
5" of storage in the aeration tank,
which is conveniently used to con-
tain the surge quantity. The ef-
fluent weir box device is located at
the end of each collection pipe. It
controls the flow rate through the
Split-ClarAtor. This in turn "backs
up" the operating level throughout
the plant during peak flows. The
first weir sets a minimum level and
freely passes any flow below the
rated capacity of the Split-Clar-
Ator. The second weir is a sub-
merged orifice and it freely passes any flow until the
rated capacity is approached. At that point, the
second weir (orifice) begins to restrict the effluent
flow and it takes over control. It is sized so that the
maximum SOR is not exceeded. If an abnormally
high or prolonged influent flow occurs, the water level
in the plant would rise to a level above the third weir.
This weir allows emergency high effluent flow rates to
overflow and bypass the first two weirs. It is at this
point that the Split-ClarAtor acts like any other
clarifier, i.e., what comes in must go out. This surge

control system offers "intank" storage to handle high
diurnal peak flows and lift station surges without
appreciably affecting the surface overflow rate of the
clarifier. The surge storage volume is equal to 5"
across the aeration and clarification tanks. It also
offers a unique means of diverting mixed liquor to a
side line surge tank to absorb peaks flows above the
5"depth. This diverts excess flow for later processing
in the aeration tank and clarifier.

Leveling the weirs in the plant to insure even drawoff
across the entire clarifier is simple. The effluent
launders do not require leveling, only the weir box
assembly. These are easily adjusted up and down by
hand and without tools. The plant liquid is brought to
operating level, and the weir boxes, held by spring
tension, slide up or down to match this level.

At times it may be necessary to prevent loss of solids
by shutting off the effluent. This could be during
normal housekeeping operation or other main-
tenance activities.
The second weir (submerged orifice) is a calibrated
orifice located in a swing gate which can be changed
ff necessary. A simple, manually operated swing gate
is provided for each effluent weir box. This is made
from plastic and simply slides over the submerged
opening in the effluent box as a blank plate to block
the flow. The swing gate is operated by simply swing-
ing its handle back and forth. One flow gate can be
shut off at atime, or as manyas desired if the plant has
morethanone.
14 WALKWAYS AND HANDRAILS.
An aluminum grating walkway covers the full length of
each Split-ClarAtor for easy access. The handrails
are constructed of either smooth galvanized tubing or
aluminum, and are connected with cast aluminum
alloy fittings. The top rails are 42" above the walkway,
and the center rails are 21" above the walkway.
Handrails are fastened to the Split-ClarAtor module
with stainless steel sockets that are welded to the
support beam. Each socket is drilled and tapped for
two 1/2" stainless steel locking bolts. All of the hand-
rails are connected to each other, forming a con-
tinuous and unbroken assembly. This includes hand-
rails on adjacent units, auxiliary walkways, and
peripherals.

Effluent with clchanging the way the world looks at
sewage ... in a manner of speaking
Carrie Miller
Staff Writer
A sewage plant designed by a
former Kansas State University
professor has been winning
9 national awards —and interna-
ional contracts.
Larry Schmidd was in civil
engineering at K-State for 10
years before his attention
turned toward one of his specif-
ic interests —sewage treatment.
Now Aero-Mod, the company
he founded in Manhattan seven
years ago, is winning contracts
all over the United States, Mexi-
co and most recently, South
America.
Aero-Mod employs 20 people,
buildingwhat Schmidd calls the
Cadillac of wastewater treat-
ment equipment.
One prototype of the system
built in 1991 inBlue Township —
just east of Manhattan in Pot-
tawatomie County — won the
U.S. Environmental Protection
Agency's multi -state regional
"operation and maintenance"
award in 1995 and 1996. The sys-
tem also took a second -place
national award for wastewater
management excellence in
1996.
The plant has had no bypasses
of raw sewage, even during the
flooding of 1993, plant manager
Steve DeHart said. DeHart
works for Aero-Mod.
So what exactly is so different
about the Aero-Mod system?
Its philosophy emphasizes
easy -to -use equipment, low
maintenance and a high quality
"effluent" (the end product —
treated water expelled into the
river), DeHart said.
By the time the raw sewage is
processed and the effluent
leaves the facility, many of the
pollutant levels are within
drinking water standards,
DeHart said.
Or, as the president of the
company put it: "We put our
effluent out there and pollute it
with the river."
They're so proud of their
effluentthat the showcase Aero-
Mod facility being built in Santi-
ago, Chile has an effluent moat

landscape plants.
The system is similar to most
modern wastewater treatment
facilities in that it uses natural
biological processes.
The raw sewage, known
around the plant as "food," natu-
rally contains bacteria, which
they call "bugs" that eventually
digest the sewage. To speed up
the process, biological treatment
processes agitate the food and
pump in oxygen, which the bugs
need to live.
Biological treatment facilities,
like Manhattan's wastewater
plant, li&d`a series of tanks and
pumps to move the food along,
with painted steel stirrers to agi-
tate the food.
Aero-Mod's system, on the
other hand, uses one main tank. It
also uses gravity and forced air to
agitate rather than a lot of pumps
and moving parts, Schmidd said.
"Those type of pumps have to
be cleaned out nearly everyday,"
he said.
Because most of the Aero-Mod
system is made of stainless steel,
rather than painted steel, it is
long-lived and requires little
maintenance, Schmidd said.
It is also user-friendly in that
there are only two controls in the
place, DeHart said — one to con-
trol the aeration timer and one to
concentrate the waste.
Danny Hembree, the operator
of the Blue Township plant, has
enough time on his hands to run
two other treatment plants and
two drinking water plants.
By contrast, there are 10
employees at Manhattan's
wastewater treatment facility,
according to Scott Townsend,
Manhattan wastewater treat-
ment plant supervisor.
"Maintenance is a good part of
what they do," Townsend agreed.
Manhattan's plant is much
larger than the Blue Township
facility. Blue Township is set up
to serve 10,000 people; Manhat-
tan's can handle 43,000. Manhat-
tan's plant is expanding to han-
dle 58,000 by this fall.
But with an Aero-Mod system
in place, Manhattan would prob-
ably only need 3 to 4 people to run
it, DeHart said.
Manhattan's plant is switching
over to a similar process of using
forced aeration to activate the
bugs that eat the sewage. But that
won't cut the number of employ-
ees at the plant, Townsend said.
Aero-Mod has numerous
patents for different processes
Schmidd has developed.
One, known as SEQUOX, is a
way of causing the bugs to con-
sume more polluting phosphates
and nitrates than they ordinarily
would.
*turningthe oxygenoffsome-
times, "we trick them," DeHart
said. Without the free oxygen
they need to live, the bugs turn to
oxygen bound in nitrates. They
consume the oxygen and the
nitrogen comes off in a gaseous
form.
Depriving the bugs of oxygen
also causes them to panic, and
drop all the phosphates they're
carrying, DeHart said. When the
oxygen comes back on, they re-
absorb the phosphates at even
higher levels.
Another good thing about
Aero-Mod facilities is they are
easily expandable, DeHart said.
With no moving parts below the
surface of the water, all that's
needed is more tank space.
The Blue Township facility
will be doubling in size this
spring. The cost: $250,000,
DeHart said.
Now handling up to 100,000 gal-
lons of sewage per day, it is
expandable up to 1 million.
"I had a hard time selling it at
first," Schmidd said. "Project
engineers would say to me'I don't
need a Cadillac, I can't afford
that.'
"But once I got them to look at
the bottom line, they realized it
was less expensive, not more."

When it comes to designing
waste waster treatment plants,
there's no project too big or too
small forLarry Schmidt and his
Aero Mod crew.
Schmidt, who founded Aero
VIod Inc. in 1978, has applied
its innovative concepts to
vastewater plant facilities,
serving as many as 50,000 cus-
tomers, all the way down to a

currently building a wastewate
treatment plant in Mexico. Aero
Mod Inc. has also designed
wastewater facilities for General
Motors.
Schmidt said six of his
designs have been patented.
Schmidt built his business by
nurturing two basic goals: relia-
bility and simplicity.
"We're not a manufacturer
that manufactures equipment
that looks like everybody
elses," Schmidt said. "We want
to sell a solution. We work with
every client and create a pro-
cess that solves a problem."
Two years ago, Schmidt con-
verted his waste waster sys
tems to all stainless steel parts.
He said stainless steel is lighter
in weight and lasts longer. Aero
Mod waste waster systems are
low maintenance and have no
moving parts and minimal elec-
trical parts.
"Wastewater is put into a
stream and eventually nature
breaks it down," Schmidt said.
"We take wastewater, and do
what nature does in a matter of
hours. We produce high quality
water in a short period of time.
It's just a different way to do it."
• Schmidt said the treated
wastewater released from an
years ago. Today he employs a
staff of 18.
"I liked teaching, 'but I've
found business to' -be more
exciting," Schmidt said. "You
have more opportunities, and
more control over whatyou do."

sent facility, located at 7927 E.

such as the Northeast, even service
jobs were in trouble. New York,
which has a large crop of financial
services workers, had little
employment growth. Typical of
this state's problems, are consoli-
dations like the merger of Chemi-
cal Banking Corp. and Chase Man-
hattan Corp., announced Aug. 28.
As a result of this transaction,
which will create the nation's
biggest bank, 12,000 workers will
be fired.. ,
"It could be an awfully big hit to
an economy that already is show-
ing only minimal job growth," said
David Hensley, a real estate ana-
lyst with Salomon Brothers.

r
Aero Mod designed system can
be used on crop land for irriga-
tion purposes. He said the tech-
nology is available to convert
the wastewater into drinking
water.
"In this country. it makes
sense to put it back," Schmidt
said.
The jewel of Schmidt's
wastewater concepts is a device
called the "The Clarator." The
Clarator can skim water off the
top of holding tanks after bacte-
ria has had time to settle to the
bottom.
Schmidt demonstrated this
process by dipping a cup into
the mixing tank. The bacteria
sunk to the bottom and semi -
clear water was visible on top.
Water taken from the Clarator
device was fairly clear. The top
half is what is skimmed by the
Clarator.
The basic Aero Mod wastewa-
ter system is comprised of three
large tanks. The middle tank
mixes the water and guides it
into the Clarator device. The
treated water that was skimmed
goes into one tank, while the
bacteria -laden water is dis-
tributed to the sludge tank.
Blue Township's sludge
machine features 12 huge bags,
each weighing 180 pounds when
full. The sludge is sent from the
tank into the bags where it is
compressed into the bag by a
blower. When full, the bags are
stacked outside to dry and even-
tually hauled to the Pot-
tawatomie County Landfill.
Blue Township was recently.

tal Protection Agency with an

Schmidt estimated Aero Mod

wastewater systems now in
operation. The overall cost
varies according to the need,
but Schmidt said the cost of con-
structing the plants. usually
costs from $100 to $200 per cus-
tomer served.
"There are 50 different states
each with different standards,"
Schmidt said. "That's why you
can't have a piece of equipment
that fits everybody. You have to
adapt."
Schmidt backs up his designs
with a warranty plan and main-
tains contact with the customer
even the warranty has expired. -
"We maintain parts and ser-
vice, and serve as a consultant
for operational problems," I
Schmidt said. "You end up

Local treatment plant recognized
Six Kansas municipal wastewater treatment systems are winners
in the U.S. Environment Protection Agency Region 7 annual Waste-
water Operations and Maintenance Excellence Awards Program.
The plants are the Blue Township Wastewater Treatment Plant, Pot-
tawatomie County; Concordia Wastewater Treatment Plant; Indian
Creek Middle Basin Treatment Plant, Johnson County; McPherson
Wastewater Treatment Plant; Ottawa Wastewater Treatment Plant;
and the Oakland Wastewater Treatment Plant, Topeka.
The awards recognize municipal wastewater treatment plants in
the region's four states of Kansas, Iowa, Missouri and Nebraska.
"EPA and the state environmental agencies have instituted vari-
ous initiatives to remind treatment facility operators that good,
sound operation and maintenance practices protect our nation's
lakes and streams from polution," Region 7 Administrator Dennis
Grams said. "As regional winners, these communities have demon-
strated their commitment to the preservation of water quality in Re-

The Blue Township (Manhattan) Wastewater Treatment Plant will
receive a Region 7 0&M Excellence Award in the category of Small
Secondary Treatment for plants that treat less than 1 million gallons
a day (MGD) of wastewater.
The Blue Township facility was designated and built by AeroMod
Incorporated. It serves 231 households in a 2.25-square-mile area of
Pottawatomie County.
The plant has had no violations of its operating permit since it was.
built in 1991 and no bypasses of raw sewage, even during the flooding
of 1993. Innovative techniques at the plant have saved the county
money and produced high -quality treatment results. Timed aeration
within a single mixing tank has decreased electrical consumption,
reducing operating costs. The process has also reduced new con-
struction costs.
Adding to the plant's exceptional compliance record is its unique
design and construction. The facility is built of cast -in -place concrete
and stainless steel, with no moving parts or need for electricity in
many of the plant processes. This keeps costs down and maintenance
and breakdowns to a minimum.

is an Aero-Mod designed treatment facility located in Pottawatomie County, Kansas. Aero-Mod's philosophy places emphasis
,rator friendly designed equipment, low maintenance operations, and facilities that produce a high quality effluent. Tankage is
t-place concrete, the equipment is primarily fabricated of stainless steel and aluminum, and there are no moving parts or elec-
:quipment below the water. At present daily plant operations for this facility require approximately one hour per day, thus reduc-
erational costs.
.cility which was constructed without Federal or State of Kansas funds, services an area of approximately 2.25 square miles with
tlation of 1,000. It has had no violations of its permit since it was constructed in 1991 and no bypasses of raw sewage, even
the flooding of 1993. Bids for construction of Blue Township

water Treatment Facility went out January 10, 1991, and were
:ed January 28, 1991. The facility is designed in several phases
he first part of the system designed to handle o.10 MGD and latter

can be expanded up to 1.0 MGD capacity. r� j:. - - 1■t MINN.
gh research conducted at the Blue Township Facility, several inno- t _
techniques were incorporated with plant operations which have Ig
ced a high quality effluent. The resulting effluent discharge pro -
yearly averages for total suspended solids at 4.5 mg/L, B.O.D. lev- - "a

Another research project involves the
unique method of handling sludge bio-solids. The
facility utilizes an automatic DRAIMAD sludge
dewatering system. This pressurized equipment
economically places the dewatered sludge in a spe-
cially fabricated bag for convenient storage and
handling.

The success of this plant is based on the
efforts of many individuals that range from our dis-
tinguished Pottawatomie County Commissioners '
to the Blue Water Services operational staff. '
Special consideration and thanks go out to Larry
Schmid, Sherry Ridder, Darlene Siegle, and Danny
Hembree for their dedication to achieving a quali-

Sludge Disposal Alternatives Analysis

PLANT EXPANSION ALTERNATIVES 5A, 5B, 5C, 5D, AND 5E
SLUDGE DISPOSAL ALTERNATIVES
PRESENT WORTH ANALYSIS
A. Alternative # 1 - Land Application
This alternative would involve the use of the town's existing sludge hauling truck for
transfer from aerobic digesters to an application field. Additional digester volume would
be required in order to provide 60 days of sludge storage at 10 deg. Celsius to meet EPA 40
CFR part 503 regulations. This would be accomplished by converting the existing sludge
holding tank, presently not in use, to an aerobic digester. Its volume is 150,000 gallons,
therefore an additional 20,000 gallons of new digester volume would also be needed. Since
the existing application field is too small for the 20-year design and because of
contamination in the monitoring wells, a new application field would be required:
1. Sludge Treatment:
Sludge wasting @ 1.5% solids = 5,781 GPD
60 days storage = 60 x 5,781 = 346,860 gal.
Existing digesters = (2)(21' x 16.5' x 8.6')(7.48) = 44,580 gal.
Therefore, additional digester volume required =
346,860 - 44,580 = 302,280 gal.
150,000 gallons available
Add 152,280 gal. to sides of old and new plants
2. Land:
Application rate = 5 TN/AC/YR
Expected application = 5,781 GPD @ 1.5% solids = 132 TN/YR
Therefore, application area = 132/5 = 26.4 AC
For 100' Buffer area: 10.8 AC required if property is square
Total land required = 26.4 + 10.8 = 32.7 AC

3. Capital Costs:
Convert 150,000 gal. Holding tank
to aerobic digester $100,000.00
Supernatant Pump Station and Force Main 50,000.00
Additional 152,280 gal. Digester Vol. 150,000.00
New Application Field: 37.2 AC @ $5,000/AC 186,000.00
Monitoring Wells: 12 @ $5,000/EA 60.000.00
Subtotal $5465850.00
Engineering (10%) 54,600.00
Contingencies (10%) 54,600.00
Total $655,200.00
(Note: truck purchase is a sunk cost)
4. O & M Costs:
a. Testing $5,000.00/YR
b. Lime, and nutrients not in sludge: $4,000.001YR
C. Application Labor: 1-1/2 hrs. per truck
load, truck volume = 3,200 gal., labor
_ $21.00/man-hour
Year 1: 0.240 mgd avg. annual flow and 2,313 GPD sludge wasted
Year 20: 0.600 mgd avg. annual flow and 5,781 GPD sludge wasted
Therefore, 264 loads/year first year and 660 loads/year the 20'h year:
Year 1: 264 x 1.5 x $21 = $ 8,316.00
Year 20: 660 x 1.5 x $21= $20,790.00
d. Truck maintenance, gas, etc.: $0.25/mile
If new field is near town, assume 10 mile round trip
Year 1: 264 x 10 x $0.25 = $ 660.00
Year 20: 660 x 10 x $0.25 = $1,605.00
e. Mowing and Baling Crop: Assume cost = revenue from sale of hay
Total O & M =
Year 1: $5,000 + $4,000 + 8,316.00 + 660.00 = $171)976.00
Year 20: $5,000 + $4,000 + 20,790.00 + 1,650 = $31,440.00

6. Total Present Worth:
P.W. _ $655,200.00 + 22703 - 18,538 - 75,485
_ $788.860.00
B. Alternative #2A - Transport Sludge to Shelby Composting Facility
This alternative would also involve use of the existing sludge hauling truck. Because
the sludge would begin the PSRP at the Shelby WWTP, only 30 days of sludge storage is
needed at the Boiling Springs WWTP. The sludge would be thickened within the digesters
to an average of 1.5% solids. The sludge would be introduced into the Shelby WWTP WAS
pump station, therefore a short pipeline would be needed to transfer the sludge from where
the truck can park over to the pump station.

• 201 FACILITIES PLAN - PUBLIC HEARING
APRIL 17, 1997 - 7:00 PM
Attendance: Mr. Rick Howcll, Town Administrator (Hearing Officer)
Mr. Jerry Twiggs, West and Associatcs, P.A.
A public hearing was held on Thursday, April 17, 1997 - 7:00 PM to solicit public comment on
the proposed 201 Facilities Plan update and wastewater treatment plant expansion project. Mr.
Howell, Hearing Officer, declared the hearing open at 7:00 PM. Mr. Howell acknowledged the
presence of Mr. Jerry Twiggs, West and Associates. Mr. Howell explained that Mr. Twiggs is a
representative of the town's consulting engineering firm which assisted with plan preparation.
Mr. Howell provided the following information:
1.) The public hearing had been advertised on March 17, 1997, as required, at least one time
thirty (30) days prior to the hearing as evidenced by the publishers affidavit from the
Shelby Star included in the 201 Facilities Plan.
2.) A copy of the 201 Facilities Plan has been available in the Office of the Town Clerk for
public inspection since March 31, 1997.
3.) Identified the current problems experienced by the wastewater system over the past two
years. This included a brief description of current situation with the collection system,
pumping stations, and wastewater treatment system. Mr. Howell referred to each section
noting specifics in the plan. Mr. Howell further explained that the WWTP was reaching
its capacity and in some months exceeding its ability to effectively provide adequate
treatment and thus had been in violation of its NPDES permit on numerous occasions.
4,) The alternatives considered were also briefly discussed. These included spray irrigation,
subsurface disposal, transportation of wastewater to Shelby, taking no action and
expanding the existing WWTP. Mr. Howell stated that the alternative chosen by the
Town Board is to expand the existing wastewater treatment plant form .3 MGD to .6
MGD. Mr. Howell stated that the Board felt this alternative was the most cost effective
taking into consideration the overall capital cost, customers served, future growth and
impact on the sewer rate.
5.) Mr. Howell stated that the original loan request was $ 700,000. accompanied by a request
for a $ 100,000. high unit cost grant. The Town was informed that the grant would most
likely not be available. The Town has since amended its loan request to $ 900,000. The
Town will contribute approximately $ 138,000. to the project.
6_) Mr. Howell also stated that the Town's current land application of sludge was being
reviewed and that an agreement to haul sludge to the City of Shelby's composting facility
• had been agreed upon through a letter of understanding with city officials. It is estimated

that at the beginning 5,000 gpd will be hauled to the Shelby facility. The Town Attorney
is currently working on drafting a formal agreement which will be discussed by the
respective governing bodies at Board meetings scheduled in May.
7.) Mr, Howell stated that the typical residential sewer bill in Boiling Springs averaged 5,000
- 6,000 gallons per month. The current sewer bill for 5,000 gallons is $ 10.35 with a
combined water/sewer bill at this consumption being $ 26.25. The proposed project
would increase a sewer bill at this consumption to S 21.53 with a combined water/sewer
bill being $ 37.43.
Mr. Howell made note of the time as 7:45 PM and stated that there being no citizen present to
address the issue that the hearing be declared closed.
The following minutes are a true and accurate record of the proceedings which took place on
Thursday, April 17, 1997 concerning the issue of the amended Boiling Springs 201 Facilities Plan

Mayor Hamrick recognized Mr. Howell, Town Administrator, for a report on the status of the
WINTP. Mr. Howell reported that the formal contract with Culligan Operating Systems was
complete and was signed and put into effect on March 1, 1996. Culligan has made several
recommendations for improvements to the plant and these were proceeding with funds budgeted
in FY 95.96. Mr. Howell also reported additional III work was being delayed due to Inclement
weather. Smoke testing and visual inspection of manholes would begin again as soon as
weather permitted. Mr. Howell informed the Board of the non compliance status of the WVV TP
citing problems indentifled by Culligan. These problems are being addressed on a day to day
basis He also brought the Board up to date on the status of the SRF Loan/Grant application
submitted to the Construction Grant and Loan Section. The application has been forwarded to
the section and contact has been made with the Local Goverment Commission.
Mayor Hamrick recognized Mr. Chester West to discuss the funding process and the scope of
the WWTP expansion now being reviewed. Mr. West explained that a careful review of the
Town's option in regard to what type of expansion could take place was necessary. He stated
that the original plant design would allow construction of another Aeromod module however it
would be necessary to look at other options to determine compatibility as well as cost
effectiveness. Mr. West stated that the Town could ill afford not to proceed cautiously when
making a decision about what type of plant expansion to undertake. He also emphasized that
the State would have to review and agree with the Town on this issue. Mr. West addressed
concerns expressed by the Board about the impact the loan would have on the rate structure.
Mr. West stated that initially this has been calculated but that until we proceeded further on to
determine more definitely the amount of capacity and scope of the project it would be
speculation. Mr. Howell stated that any rate increase would be significant since the Town had
not increased sewer rates since 1990. He also informed the Board that the LGC would scrutinize
the rate structure and would not allow a combined waterlsewer bill for the average customer to
exceed a certain amount based upon economic indexes for the Cleveland County area. As we
get closer to determining a rate structure the Board would be informed what to expect.
Mr. Howell discussed the need to enter into a Special Order By Consent with the State due to
past and current non compliance problems. The SOC would basically set out a schedule for
compliance and expansion of the WWTP, a financial settlement amount for past non
compliance, and provide for modified testing parameters which would allow the Town to stay in
compliance for the period set forth in the agreement. The SOC is critical to avoid further
enforcement action as well as to establish a plan for compliance achievement.
The Board directed Mr. Howell and Mr. West to proceed with the necessary steps to bring the
WVVTP into compliance and reaffirmed an earlier commitment of local funds up to $150,000.
toward necessary improvements to the plant.

Note: The following are excerpts from a public meeting held December 3, 1996.
Mr. Howell discussed the alternatives that have been identified for sludge management These
include continuing with the existing 12 acre dedicated site, seeking a new dedicated site,
pursuing non dedicated sites and finally contracting with the City of Shelby to accept sludge at
their WWTP sludge facility on NC Hwy 1 a south. The last option is preferable if details can be
worked out. This would ential agreement by Shelby, which they have informally given, and
amendments to both cities NPOES permits. Mr. West and Mr. Howell will continue to explore
these options and report to the Board as appropriate.
Mr. Howell reported to the Board that Mr. West would submit plans and specifications to Raleigh
as required in the proposed SOC by December 31, 1996. It was agreed by staff, officials from
Culligan Operating Services and West and Associates that expansion should take the form of a
comparable package plant to the existing Aeromod system. It was taken into consideration the
limits of the existing Aeromod plant and the operational limitations which were apparent. The
report received from the Municipal Compliance Initiative Program was also taken into
consideration. However, after reviewing proposed costs for various types of expansion it was
determined that if would be more cost effective and beneficial to pursue a package type plant
Note: The following is an excerpt from the March 4,1997 Regular Meeting of the Boiling
Springs Town Board of Commissioners.
Mayor Hamrick recognized Mr. Chester West for a status report on the Town's effort to expand
the existing WWTP. Mr. West brought the Board up to date on the status of funding and the 201
facilities plan. Mr. West stated that it appeared funding may be available in mid to late summer
1997 but that no firm commitment would be made until plans and the 201 facilities plan were
approved. Mr. West informed the Board that there were issues which needed to be resolved
regarding the 201. The most significant Involved justifying the amount of requested expansion
based upon population growth. The State has historically used growth figures provided by the
Office of Budget and Management which uses County growth statistics to project municipal
growth. This is not a good indicator because statistics clearly show the Town to be growing at a
much faster rate than the County as a whole. Growth at Gardner Webb and in Town will be
documented and forwarded to the State to address the issue. The other major issue involves
addressing concerns expressed by the State regarding the type of system included in the plans
and specifications. These will be addressed and an answer to the State's concerns will be
forwarded on as soon as possible.
Mr. West addressed several questions from Commissioners involving the proposed timetable
and the need for expediency, specific concerns regarding the need to clearly communicate that
Boiling Springs is growing at a much faster pave than all of the rest of Cleveland County as well
as malting sure that the proposed rate structure were reasonable and acceptable to the LGC.
Mr. Howell informed the Board that the projected rate structure would and must be confirmed
and approval sought from the LGC.

Note: The following are excerpts from the April 2, 1996 Regular Meeting of the Boiling
Springs Town Board of Commissioners.
Mayor Hamrick recognized Mr. Howell to report on the status of the Special Order By Consent
for the WWTP. Mr. Howell reported that he, Mayor Hamrick, Mr. West. Mr. Kennedy, Town
Attome} , Mr. Kevin Jones, Culligan Operating Services, met with OEM Regional Officials in
Mooresville to discuss the current non compliance situation. Mr. Rex Gleason has informed the
Town that in order to avoid additional enforcement action the Town may wish to consider an
SOC as soon as It deems possible. This is due to past non compliance as well as current non
compliance. Mr. Gleason emphasized that a penalty would be included in the SOC based upon
past non compliance.
Mr. Howell informed the Board that it had been made clear to Mr. Gleason that past problems
had occured due to misinformation and neglect by, the past ORC at the plant and that the Town
had moved quickly to rectify this problem by employing Culligan Operating Services to operate
the facility. Mr. Howell stated that a draft SOC would be forthcoming in the next week or so and
that it would be presented to the Board for its approval after it had been reviewed by staff and
the consulting engineer.
Note: The following is an excerpt from a public meeting held on November 6, 1996.
Mayor Hamrick informed the Board that Mr. West had submitted his initial recommendation to
the Town regarding the type of expansion for the WWTP. He stated that Mr. West may wish to
alter this recommendation depending upon the findings and recommendations of the team from
OEM which conducted a Municipal Compliance Initiative review at the WWTP during September
1996. The initial recommendation involves the expansion of the existing .8 MGD plant to .6
MGD using a package plant similar to the one in place now_ Mr. Howell informed the Board that
it would be important to avoid excluding bidders from process to comply with public bidding laws
and to achieve a competitive bid for obvious financial reasons.
Commissioner Glenn commented that if possible and if funds were available it would be wise to
build additional capacity. Mr. Howell stated that he and Mr. West felt they could adequately
justify an additional .3 MGD based upon GWU and the residential growth in Town but that any
more than that would be difficult to justify and the State would Certainly bring this to our attention.
Mr. Howell stated that there would be a limit to the amount of money the LGC would let the Town
borrow based upon the impact upon rate structure and that additional expansion would have to
be financed from Town coffers: This he said was not an option based upon the Town's past
commitment to this project as well as sewer line replacement and In programs.
