HARPERS FERRY -BOLIVAR PUBLIC SERVICE DISTRICT
ANALYSIS AND PRELIMINARY ENGINEEFUNG REPORT
I.
INTRODUCTION
A. The Harpers Ferry-Bolivar Wastewater Treatment Plant is a 300,000 gallons
per day (0.3 MGD) facility owned and operated by the Harpers Ferry-Bolivar
PSD. The plant was built in 1976-77 to serve the combined population from
the Towns of Harpers Ferry and Bolivar, WV and is located in the Harpers
Ferry Magisterial District. The treatment facility basically consists of a
comminutor and bypass bar screen structure, aeration tanks, settling tanks, and
primary and standby chlorine contact tanks. In addition, sludge holding tanks
and sludge drying beds are part of the facility. An officelcontrolilab building,
emergency generator building and a garage building round out the structures
on the site.
B. A site map providing the plant location is included in Appendix A. The site
plan of the treatment plant is included in Appendix B.
C. This report is limited to a review of the scope and needs for improvements
required to maintain the present WV/NPDES effluent limitations at the
Wastewater Treatment Plant. The report will also address pending future
changes in the effluent limitations in the area of nitrogen and phosphorus
removal as they might affect this plant. The scope of work for this report does
not address any o€ the potential needs for the collection and pumping systems.
The general condition of the plant, due to the age and condition of plant
equipment, provides a daily threat to not meeting the NPDES Discharge
Limitations. Three specific areas of plant, after examination of the physical
plant and the operations, need attention in the immediate future. These three
areas are as follows: (1) the replacement and upgrade of the raw sewage
screening facility; (2) the settling tank scum removal system: and (3) the
addition of a sludge belt filter press system to replace the existing drying beds.
D. The West Virginia Infrastructure Council-“Required Contents of a
Preliminary Engineering Report” was followed in preparing this report.
11.
CURRENT’SITUATION
A. SOURCEDISCWARGE
The plant receives wastewater from the Harpers Ferry-Bolivar Public Service
District sewage collection system. The receiving stream of the plant discharge
-1-
is the Sbeiiandoah River approximately one mile south of its junction with the
Potomac River, via Outlet No. 001.
B. CUSTOMERS
The plant is designed for a population of 3000 including residential and
nonresidential customers all of which are metered water customers. At
present, approximately 750 customers are sent a monthly bill, representing
approximately 2,625 users. Included in the customers are a considerable
number of businesses and other commercial enterprises, including the
National Park Senice, operators of the Harpers Ferry National Historical
Park.
The treatment of wastewater from the visitors to the numerous restaurants and
other establishments within the service area accounts for the difference
between normal and expected domestic flow and the actual flows received.
C. COLLECTION SYSTEM
As previously mentioned, the scope of work for this report only, addresses the
Harpers Ferry Wastewater Treatment Plant only.
D. TREATMENT
The existing wastewater treatment plant has a design capacity of 300,000
gallons per day and includes a combination bar rack and communitor
chamber, two (2) 151,500 gallon each diffused air aeration tanks, two (2)
26,350 gallon each settling tanks, two (2) 24,400 gallon aerated sludge
holding tanks, chlorination facilities with one 12,850 gallon primary chlorine
contact chamber and one 6,425 gallon standby chlorine contact chamber. The
original design also included four (4) 41’x 18’ sludge drying beds that were
subsequently converted to two 41’x36’ beds with concrete floors to improve
the dewatering and facilitate sludge cake removal. Use of the sludge drying
beds is limited to 8-9 months per year. During the winter months, waste
sludge is collected in a bag retrieval system that is totally inadequate to meet
the required sludge removal and maintain the required biomass level in the
treatment plant. A site layout and diagram of the plant are included in
Appendix B. Basic Design Criteria and capacities of the sbuctures are
presented in Appendix C. Photographs of several of the treatment units are
found in Appendix D.
Several components of the existing facilities are in poor physical condition
with the comminutor not operable and beyond repair. This not only impacts
rags and other solids normally removed, but also contributes to the scum and
attached solids that pass through the plant and are visible at times in the plant
effluent. Also contributing to the scum problem is the nonfunctioning scum
-2-
removal system on the settling tanks. The design of the primary chlorine
contact includes a solids hopper where solids that are carried over to the
chamber settle out and are returned to the aeration tank. Occasionally, the
flow from the chlorine tank hopper is as thick and dark as the retuni sludge
from the settling tanks. Solids carry over is a major problem at the plant.
Photographs of the plant effluent and settling tank both showing severe scum
and solids overflow are included in Appendix I).
Another problem that contributes to the scum build up is the inadequate solids
removal (sludge wasting) from the system. Plants that have liberal effluent
limitation can maintain higher mixed liquor solids concentration which in turn
reduces the amount of solids for disposal. This has the potential for reduced
costs of the solids treatment, drying and disposal. The negative impact is
slightly higher power costs and added scum generated from the over aeration
and increased mixed liquor suspended solids. This appears to be the case for
the Harpers Ferry Plant, as the reported sludge disposal is significantly lower
that what is predicted for the average monthly flow from the plant. Appendix
E includes reported sludge quantities and calculations for anticipated
quantities.
A chief operator and one assistant operator staff the plant. The operators are
Bureau for Public Health Certified:
Mr. Jimmy Williams - Class IC - WC0201
Mr. David Tennant - Class I - WW5949
The hours of manned operations are from 8:30 AM to 12:30 PM weekdays.
A financehdministrative manager is present as needed.
E. NEED FOR THE PROJECT
The threat of pelinit violations due to the conditions described above is the
primary driver for the project. The operators must provide an inordinate
amount of time and resources to remove the scum to keep the plant in
compliance and dewater and dispose of waste sludge. Also sludge drying bed
operations are limited to 8-9 months due climatic conditions and the waste
sludge bag system used during the winter is totally inadequate. Consequently,
three immediate improvements are required to maintain effluent limitation
requirements and improve efficiency of operations.
1. A new screening system is required for the plant influent chamber.
2. Settling tank improvements for scum removal.
3. A sludge belt filter press system to improve the solids and scum
removal from the Plant.
-3-
In addition, to the immediate needs, these improvements will aid in the
additional treatment that may result in meeting the proposed WVDEP effluent
limitations for Phosphorous and Nitrogen as discussed below and under
Section VI1 - A.
F. EXISTING PERMIT
The plant has a NPDES Permit No.WV0039136 issued 11-MAY-2000 and
due to expire 11-MAY-2005. The permit Discharge Limitations include:

Conversation with the West Virginia Division of Environmental Protection Office of Water Resources - Permit Support Team indicates that for the next
renewal, the Discharge Limitations and Monitoring Requirements will remain the
same as the current limits with the addition o f Total Phosphorus and Total
Nitrogen monitoring. This could have an impact on the treatment facilities
depending on the discharge limitation levels set forth by The Division of
Environmental Protection and anticipated Chesapeake Bay Watershed
Partnership. The goal for the Partnership is to achieve and maintain a 40 %
nutrient reduction.
Since February of 2004, permitted wastewater treatment facilities must monitor
and report Total Nitrogen and Total Phosphorous content in the plant discharge.
This requirement is in preparation for the DEP proposed effluent limits for
Phosphorous and Nitrogen of .5 mgil and 5 mgil, respectively. This limitation
quantity is for treatment facilities of a size range between 50,000 and 399,000
gallons per day. The Harpers Ferry- Bolivar Plant is 300,000 gallons per day.

Recent testing and analysis indicates the following effluent levels as follows:
1. December 04: N-21.2; P-4.2
2. January 05: N-23.6; P-2.82
3. February 05: N-21.4; P-2.92

111. FUTURE SITUATION
A. POPULATION PROJECTIONS
The population of the combined drainage area of Harpers Ferry and Bolivar is
almost the same and still less than the 1990 design year population figure of 3000
persons. Since the developed area i s practically surrounded by the Harper’s Ferry
National Historic Park, growth is questionable. However, monitoring the
attendance records at the Park will continue to be important. While the trend has
seen a decline over recent years, the addition of new land to the Park and the
continued renovation of buildings within the Town area of the Park may
ultimately reverse the visitor trend and cause an upswing in the quantity of
wastewater generated. Currently the Park population contributes approximately
6.5% of the plant influent. A recent report of Park attendance is included in
Appendix G and flow impact is provided in Appendix H.
B. FLOW PROJECTIONS
From the most recent records obtained from the plant operators and EPA, the
highest average daily flow, based on the month of March 2003, was 335,000
gallons per day with a maximum daily flow over the same period of 648;000
gallons per day. The highest maximum daily flow of 1.13 MGD was reported to
have occurred during December of 2003 and was within the design maximum
flow of 1.2 MGD. During the three (3) consecutive months reported for October,
November, and December 2003 it appears that Requirement No. 14 in the Permit,
which requires a Plan of Action whenever ninety percent of the average design
-5-
flow (0.27 MGD) is exceeded, should have been initiated due to the flows
reported of 0.327,0.289 and 0.314, respectively. Plant operations reported that the
flow meter was out of adjustment during these 3 months, and that this was the
reason for the apparent high discharge. Exceeding the average flow for three
months is an important consideration as indicated below under Section C -Waste
Load Allocation.
A tabIe entitled Historical Discharge Reports indicting the average monthly and
maximum daily flows is included as Appendix H and includes an analysis of the
portions of flow contributed by The Harpers Ferry Kational Park and infiltration
from the seurage collection system.
C. WASTE LOAD ALLOCATIONS
Our inquiry with the Division of Environmental Protection as directed for this
section of the report indicated that if the plant capacity was not increased, then no
new waste load allocation was necessary.
The treated effluent from the plant is discharged into the Shenandoah River,
approximately 1 mile from its mouth, at its confluence with the Potomac River.
The waste sludge generated from the treatment process is stored in sludge holding
tanks where aeration is supplied to keep the sludge mixed and aerobic. The liquid
sludge is withdrawn from the tanks and applied to the sludge drying beds on a
seasonal basis for dewatering. The primary method of disposal is by land
application after lime stabilization of the sludge. Currently, a local farm is
permitted as the disposal site. The sludge is chemically treated with lime to raise
and maintain the sewage sludge p1-I above 12.0 for at least 2 hours and above 11.5
for 24 hours. If unable to meet the requirements of the primary method, the sludge
is hauled to the LCS Landfill, located in Hedgesville WV. During the winter
months, waste sludge is collected in retrieval bags, dried and removed to the
landfill. A sumnary of the reported sludge quantities disposed of and calcuiated
amounts for monthly average sewage flows of 0.2 MGD (present flow) and for
0.3MGD (design flow) are included in Appendix E.
D. PERMITS REQUIRED
The Plant NPDS - WOO39136 was issued on 11 May 2000 and is due to expire
on 10 May 2005. The conditions of the NPDS Permit may require actual
reductions in Phosphorous and Nitrogen at some future date depending on the
monitoring levels reported and status of the DEP proposed Effluent Limitations as
discussed above. A Building Permit from the Jefferson County Planning,
Engineering and Building Permit Office will be required for the construction of
housing for the proposed filter press.
-6-
IV.
ALTERNATIVES
The proposed improvements as outlined helow under Section VI1 - Project
Summaries, are needed to maintain and provide for the future successful
operations of the existing plant. No additional treatment capacity is required at
this time or for the foreseeable future. There are no other municipal treatment
plants within economically viable distance to allow the transfer of sewage flows.
Specific alternatives to the proposed improvements are as follows:
1. Influent Screening System - the comminutor could he replaced, hut the
advantages of the screening system, that actually removes the screened
material from the flow stream and transfers the material in transportable
containers, outweigh the marginally higher capital costs and will provide
operational cost savings. The other alternate would he to do nothing, requiring
increased operator time to clean the bypass screen and causing deleterious
impacts on the downstream treatment units. A similar screening system was
the chosen alternative for the Shepherdstown Treatment Facility.
2. Settling Tank scum removal improvements - The first alternative would be to
do nothing. Doing so would provide for the continuation ofthe present system
of hard, laborious and ineffective manual removal. The second alternative
would be to do a complete replacement of parts and restart the existing air-lift
systems. However, historic information from this plant and others, indicates
that they do not provide adequate scum removal and that they require
excessive maintenance attention.
3. Sludge Belt Filter Press - The first alternative would be to continue with
sludge drying beds as they are. In our opinion this is not a viable long-term
option due to the seasonal limilations and wet weather impact. As discussed
earlier, the hag retrieval system, used during winter months, is very
inadequate. A second option would he to cover the drying beds. This has been
done at many other plants with mixed results. Structures tend to disintegrate
rapidly due to the high humidity and weather continues to affect the use if
walls are not included in the design. Also, if the roof is not reasonably high,
operation of equipment inside the structure is significantly difficult. For the
quantities and type of sludge produced at Harpers Ferry, the most efficient
mechanical system is the belt filrer press as compared to centrifuges and heat
treatment processes.
V.
PLAN SECTION AND PUBLIC PARTICIPATION
The recommended plan is to upgrade the plant with three improvements, as listed
hereunder and described fully in Section VII:
-7
1. A new screening system for the plant influent chamber.
2. Settling tank improvements for scum removal.
3. A sludge belt filter press system to improve the solids and scum
removal from the Plant.
Once this report, and its recommendations, is accepted by the Board of Directors
of the Public Service District, and an improvement financing plan has been
worked out, public participation will be invited as required by the R V
Infrastructure Council.
VI.
ENVIRONMENTAL INFORMATION
Since the proposed improvements will only enhance the plant operations there
will be no adverse impacts to be addressed. The plant is located in an unmapped
flood plain area, but appears to be located well above a predicted 100 year flood
elevation. The top of the treatment plant wall elevation is noted as 294.83 on the
original construction drawings and the approximate water elevation of the
Shenandoah River for the 1936 Flood of Record, is recorded at Elevation 280.03
at Harpers Ferry.
VII. PROJECT SUMMARIES
A.
ENGINEERTNG SUMMARY
In summary, the proposed project covers three improvements to maintain
effluent limitation requirements and improve plant operations to include
12-month operation of the sludge drying and disposal operations.
1. A new raw sewage screening system, sized to process the plant
maximum flow of 1.2 MGD, is required to first screen and then
remove screenings from the plant influent to protect the downstream
treatment units and allow for improved activated sludge process
efficiency. The screenings will fall into a screw compactor and
conveyed up to a discharge point where the screenings are dropped in
a container. The containers of screening will be sent to an approved
landfill. It is hereby noted that this improvement was made in 2005
and is providing very good results.
2. Settling tank improvements for scum removal, to prevent scum and
floatable solids from entering the chlorine contact chamber with the
potential of passing through with the plant effluent to the Shenandoah
River. The system envisaged would withdraw the floatable scum from
the settling tanks via a scum collection box located in each of the two
settling tanks. Submersible sewage grinder type pumps installed in
each scum box will pump the scum to the sludge holding tanks for
ultimate disposal with the waste sludge.
-8-
3. A sludge belt filter press system to replace the sludge drying beds.
This will improve the waste solids drying and provide adequate
disposal operations year round. The system shall include belt filter
press, sludge pumps, chemical treatment, controls, and transport
loading facilities. The system will be housed in an insulated metal
building that will be located on the existing sludge drying beds
concrete pads. This will allow the utilization of the existing truck ramp
for filter cake loading and the filtrate sump for filtrate collection.
4. Based on the limited testing results for phosphorus and nitrogen levels
to date, it is hard to predict exactly what type of treatment will be
necessary to meet the expected effluent requirements. The construction
of a membrane filter facility is certainly one possible method.
However, for a plant of this capacity, these units tend to be
overwhelmingly expensive. Recent advances in the use of manmade
Biological Additives for the reduction of nitrogen and phosphorus are
proving to be cost effective means of meeting this challenge. Our
recommendation is to continue to monitor the levels of these two
pollutants, and once enough data is available, to enter into a biological
testing period, using one or more of the biological additives.
Manufactures drawings, equipment information and concept sketches
for the needed improvements and are included in Appendix I, as well
as information on two of the biological additives.

2.
OPERATION AND MAINTENANCE COSTS
Existing: For the Fiscal Year Ending June 30,2005 - $140,451
for Treatment and disposal.
With Proposed Sludge Treatment Facility
$140,45 1
With the addition of the new equipment, there wil! be some
changes in the operation and maintenance costs. The complete
calculation of these costs is in Appendix J-1. In summary, the raw
sewage screen and compactor unit replaces the comminutor and
reduces manpower associated with removing materials from the
existing bar rack. The electric power requirements are comparable
and the manpower for removing the screenings bags is no more
than spent on the present screening removal operations.
The proposed scum removal system pump operation power
requirement will incur a minimal increase in power costs of
approximately $150 per year.
The O&M costs for belt filter press sludge dewatering system
should actually reduce the sludge handling costs due to a reduction
in manpower hours that offsets the increase in power and chemical
costs. The total savings in cost is estimated at $15,100. However,
for rate calculations, due to the uncertainty of which equipment
will actually be installed, the accountant has left the maintenance
cost the same for the initial calculations.

ai
Definitions
"Bypass" means the intentional divesion of waste strem.s from any portion of atreatment facility; and
(I)
"Severe propeny damage" means subs:antial physical damage to propem, damage to the treatment facilities ivhich
(2)
causes them to become inoperable, or substaitial and permanent loss ofnatdial resources which can reasonably be
expected to occur in the absence o f a bypass. Severe propem damage does not inean economic loss caused by delays
in production.
Bypass not exceeding limitations. The permillee may allow any bypass to occur which does not cause effluent limitations to be
exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the
provision of11.3.c) and Il.3.d) ofthis pernit.
(1)
If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten (10) days
before the date of the bypass;
(2)
If the permittee does not know in advance of the need for bypass, notice shall be submined as required in IV.2.b) of
this permit.
Prohibition of bypass
(1)
Bypass is permitted only under the following conditions, and the Chief may take eniorcement action against a
permittee for a bypass, unless;
Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage;
(A)
There were no ieasible alternatives to the bypass, such as the use of auxiliary treatment faciiities,
(B)
retention of untreated wastes, or maintenance during normal periods of equipment downtinie. This
condition is not satisfied if adequate backup equipment should have been installed in th--exercise
of reasonable engineering judgement to prevent a bypass which occurred during normal periods of
equipment downtime or preventative maintenance; and
The permittee submitted notices as required under 11.3.c) of this pennit.

Definition. "Upset" means an exceptional incident in which there is unintentional and temporary noncompliance with
technology-based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does
not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate
treaiment facilities, lack of preventative maintenance, or cafeless or improper operation
Effect of an upset. An upset constiktes an affirmative defense to an action brought for noncompliance with such technology) met. No determination made during administrative review of
based permit effluent limitation if the requirements of 1 1 . 4 ~are
claims that noncompliance was caused by up%< and before an action for noncompliance, is final administra!ive action subject to
judicial review.
Conditions necessary for a demonstration of upset. .4 permittee who wishes to establish the affirmative defense of upset shall
demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that:
An upset occurred and that the permittee can identify the cause(s) ofthe upset;

The raw sewage screen and compactor unit replaces the coinminutor and reduces inanpower
associated with removing materials from t!ie existing bar rack. Tlie eiectiic power requirements
are coinparable and the manpower for removing the screenings bags is no more than spent oil tlie
present screening removal operations.
The proposed scum removal system pump operation power vequireinent wi!l incur a iiiiiiinia!
increase in power costs of approximately $150 per year.
Tlie O&M costs for belt filter press sludge dewatering system should actually reduce tlie sludge

Dear Dick:
As requested please find the proforma rate calculations for Harpers Ferry-Bolivar Public
Service District. The enclosed calculations are based on the information supplied by your
firm and the West Virginia Public Service Commission reports for the District. At this
juncture, I recommend a 13% rate increase which is composed of a $7.48 service charge
and $6.61 usage charge.
Project costs were adjusted as follows:
-
0
$15,000 added for project bond counsel.
$12,000 was eliminated for capitalized interest as the West Virginia Infrastructure
Council does not assess interest during the construction period.
8
$42,332 was added to prefund the debt service reserve account on the bond issue
so that all the District's reserves remain in a fully funded position.
There is certain conflicting data in the Public Service Commission reports and elsewhere
concerning gallons of usage and effective dates of rates that will need to be worked
through as the project progresses along.
