REQUEST FOR PROPOSALS
HYDROPOWER DEVELOPMENT AT VAN NATTA DAM
Summary of Request:
The City of Ithaca, New York is seeking proposals from interested parries for development
of a small scale,run-of-the-river hydroelectric generating facility at the Van Natta Dam on Six Mile
Creek in Ithaca. Ithaca is a small but sophisticated community situated in the Finger Lakes Region
of Upstate New York. The Van Natta Dam project is a rehabilitation project consisting of a twelve
foot high reinforced concrete dam constructed in 1907, and utilizing civil features associated with
the early municipal water supply system including an existing intake structure,brick and concrete
penstock, former pumping station, and tailrace tunnel. The proposed plant generating capacity is ,
400 Kw. Estimated project capacity is based on an existing normal reservoir water surface area of
2.3 acres, reservoir surface elevation of 8.6 acre-feet, and normal reservoir surface elevation of
502.5 feet MSL. Average project head is 56.75 feet. The project is to be operated on a run-of-the-
river basis, utilizing flows between 20 and 100 cfs. A minimum flow release of 4 cfs is to be
provided and increased to 9 cfs during spring and fall.
Located within the Ithaca urban area, the site lies adjacent to residential dwellings a few
blocks from the City's Central business district. The City is desirous of having this site developed'
for hydropower in a manner which is sensitive to its historic, environmental, and recreational
features. Proposals are sought which both respond to these concerns of the locality and provide a
maximum financial benefit to the City.
The City of Ithaca is the owner of all land and water rights required for development of the
project and has been awarded a Federal Energy Regulatory Commission Exemption from
Licensing for development of the facility. The deadline for beginning construction of the project
under the Exemption is March, 1990. Construction is to be completed within two years of this start
date. The City's Exemption will be transferred to the developer chosen pursuant to this request.
The dam, associated structures, and water rights will be leased for a term.corresponding to the
length of the Exemption authorization, with stipulations for reversion of the land and transfer of
improvements to the City of Ithaca at the end of such term. The selected developer will finance,
construct and operate the hydroelectric facilities.
Pre-Proposal Conference and Site Visit:
A pre-proposal conference will be held on June 8, 1989 at 10 a.m. in the Ithaca City Hall
Common Council Chamber, 108 East Green St., Ithaca, NY. The purpose of this conference is to
describe the site, clarify the City's interests in development of the site, and answer questions
concerning the RFP.
2
Copies of the City's Exemption application*, Cultural Resources Management Plan, and the
FERC Exemption Order will be made available to those parties attending the conference upon
presentation of a certified check,cashier's check or money order payable to the City of Ithaca in the
amount of$45.00. This fee is to cover the cost of document reproduction.
An inspection tour of the site will be conducted at 1 p.m. Respondents interested in attending
the conference and/or site visit should indicate their intent to do so to Helen Jones no later than
June 5th.
Submission Requirements:
Respondents to this request must submit an unbound original and ten bound copies of their
proposal to:
M. Helen Jones
City of Ithaca
Department of Planning and Development
108 East Green Street
Ithaca, NY 14850

above address by 4:30 p.m. Questions concerning this request may be addressed to Ms. Jones by
calling (607) 272-1713.
In developing and carrying out proposals, prospective developers will be bound by the
terms, conditions, and agency requirements contained in or incorporated by reference in the
Exemption Order. Respondents may opt to base their proposals on the preliminary plan developed
by the City of Ithaca pursuant to the Exemption application, or may submit an alternative design
plan for the project. The rationale for any departures from the City's design plan must be clearly
stated along with a demonstration of the benefits of such changes. Alternative plans will be subject
to approval by the City of Ithaca, FERC, and other federal and state agencies having jurisdiction
over the project.
Respondents are cautioned against using the City's licensing documents as the sole basis for
developing their proposals. The City of Ithaca does not guarantee the accuracy of the information
and date contained in these documents, and does not guarantee that the development plans
suggested are the most viable. Prospective developers are not relieved from the responsibility for
estimating properly the effort required or costs of implementing the project.
It is understood that proposals will be based on a preliminary design level of analysis.
However, sufficient detail should be provided to allow for qualitative assessment of the technical
approach to the. project. Finalists selected for the initial award group will participate in a
simultaneous competitive negotiation process and may be asked to present more specifically
developed data at that time.

from licensing.
The Van Natta Dam is a low-hazard dam and therefore as an applicant for
exemption the City is not required to file an Emergency Action Plan.

TO THE MEW= ADDRESSED: PLANNING & pE
The Federal Energy Regulatory Commission (FERC) has the responsibility for
ensuring that exemptees 'are complying. with the terms .and conditions of issued
exemptions from license. Among the many requirements included in exemptions,
an area where compliance is particularly important, is either minimum flow
releases or reservoir operation, i.e. run-of-river-. Exemptees are often unable
to conclusively demonstrate compliance with minimum flow or run-of-river
operating requirements. Therefore, it may be necessary to install state--of-the-
art pool elevation and/or streamf low .monit_or nq equipment at all projects where
maintenance of prescribed discharges or`pool elevations is an exemption require-
ment. As you are aware,. standard exemption articles require compliance with
any terms and conditions that Federal or State fish and wildlife agencies have
determined appropriate _to prevent loss of, or damage to, fish and wildlife
resources.
As an exemptee, it is your responsibility to ensure adequate development
of data requ red ffor continuing. evaluation of compliance with operating stream-
flow requirements. Depending..on the streamflow requirements for your project,
you should consider the need for installing and providing for the operation of
pool monitoring. and/or stream-gaging, facilities at all projects, where streamf low
requirements (minimum release and run-of-river): are specified. The planning,
design, installation, and operation of such stream-gaging stations should be
coordinated with the appropriate offices of the U.S. -Geological Survey (USGS).
District Offices of the USES have been briefly apprised of this situation by
its Reston, Virginia„ office. - Mere it can be demonstrated that existing gaging
stations will provide adequate flow data, installation of additional measuring
devices will not be necessary. In addition, the type of measuring device, such
as continuous recording. or staff gaging, should be justified on .the basis of
the specific requirements imposed by agencies. If the release device can be
designed to ensure the minimum flow, at all times, such as with an open pipe
with a computed flow capacity that is maintained'properly, you should. provide
the design and computations for flow to justify use of the device as a proper
minimum flow release device.
To ensure expeditious evaluation of the need for such, action, you are
directed to furnish the " New York Regional Office, Federal Energy Regulatory
Commission, within 30 days of the date of this letter, your evaluation of the
need for and, as appropriate, your.plan and schedule for coordinating, install-
ing, and operating the necessary stations for all of your affected projects.
It should be noted that failure to comply with the. terms and conditions of your
exemption from licensing may subject you to the enforcement and penalties
provisions of Section 31 of the Federal Power Act as amended by Section 12 of
the Electric Consumers Protection Act of 1986. Should you have any questions,
please call 212-264-3687.

MODE OF OPERATION
ANNUAL ESTIMATED PROJECT REVENUES AND AVOIDED COST LEGISLATION:
In determining the estimated annual revenue to be derived from .the proposed Van
Natta Hydro Development, it is necessary to review the current status of avoided cost
legislation in the State of New York.
In 1980, New York'State enacted legislation, similar-to PURPA, to develop alternate
energy sources by encouraging cogeneration and small hydroelectric facilities. The
State law, as amended, further requires Electric Utilities to enter into long term
contracts to purchase electricity from State qualifying facilities under terms that are.
"just and economically reasonable to the corporation's rate payers; non-discriminating
to (State qualifying facilities) and'(in furtherance of) the public policy" behind the
legislation, but at a sales price not less than 6 centers.per kilowatt hour.l
Proceedings to implement the Federal and State legislation and regulations,were held
- before a respondent Public Service Commission (PSC) and culminated in an opinion
issued May 12, 198.2. On September 9, 1982 Consolidated .Edison Company of New
York petitioned the S_upreme Court - Appellate Division to review various aspects of
.S
the P .C:s opinion.l
On December 30,•1983, the Appellate Court rendered a decision which concluded that
the New York legislation had in fact required the utilities to purchase electricity from
a small power producers at a rate greater than the federally mandated rate. The
Court also concluded that "to the extent that the State requirement of a 6 cents per
kilowatt hour minimum purchase price conflicts with the Federal rule establishing a
purchase price of avoided cost, the ,State requirement has been pre-empted and is
invalid."1
L Following this action by the Appellate Court in December of 1983, there have been
two forces at work to re-establish a standardized approach for small power producers
intending to negotiate power sales contracts with New York utilities.
First, State Assemblyman, 'A. Orazio has introduced legislation to clarify the PSC's
responsibility for setting long term avoided cost rates for electric utilities. This
legislation was introduced-in May of 1984, and should be acted upon in the current
legislative session: A copy of that proposed legislation is attached.
Secondly, the New York Alliance for Hydroelectric Energy, Inc. (NYAHE) has
undertaken their own efforts to obtain long run avoided costs from the Niagra Mohawk
Power Corporation, through the P.S.C. On August 22nd, the final version of the long
run rate' settlement was reached, agreeing upon average avoided costs for 1985
j through 2005, applicable to long term contracts between small power producers and
Niagra Mohawk Power Corp.
While NYAHE does not intend to immediately pursue a similar rate case with the New
York State Electric and Gas Company, the utility serving the Van Natta Project area,
it is hoped that the P.S.C. may pursue this on their own initiative.

PROJECT DESCRIPTION &
i MODE OF OPERATION
' In conclusion, it is.difficult at this time to predict the outcome of the presently
proposed legislation and/or long term rate case for.. the project's avoided cost
structure.
It is anticipated, however, that this issue would be resolved at the time that the
F.E.R.0 had made.a decision on the approval of this project.
Based upon estimated project costs, a value of 7.16 cents per kilowatt hour would be
necessary for a first year break-even operation. For comparitive purposes, this would
i �
occur on Niagra Mohawk's Power System in 1989.
In the event that the estimated long run avoided costs for the NYSEG system fell'
i below the value of 7.14 cents per kWh, the Applicant would then consider prudent
` engineering design measures to reduce project costs during the project's final design
phase.
PURPOSE OF PROJECT
The rehabilitation of this project will mean the restoration and utilization -of a
valuable natural resourcedt is anticipated that all of the power generated at- the site
will be sold directly to New York State Electric and Gas Co:.

*Dear Mr. Tucker:
Enclosed you will find a copy of A.9444 clarifying the
PSC's responibility for setting long-term avoided cost rates
for electric utilities. In addition,. we are amending the bill
to include 'the following: 1) defining.-avoided cost and limiting
the definition -to costs associated with a utility's in-state
[_ -generation; 2) setting capacity credits based on new coal-fired
generation; 3). -tying the capacity payments to the ability of
small power producers to defer or- replace such new Capacity-
and 4) establishing a 25 year planning period for considering;
capacity assitions under a utility's generation expansion plan.
We are also attempting to c••= a time limit
- =SC =sz commoly when esta .Iis -ng long-term buyback razes aid
interconnection guidelines. Finally, we have included a limit -
on the amount of time the PSC may take when -deciding on a dispute
between a small power producer- and an electric utility.
This amendment addresses some of' the more pressing., issues
a-= prcb'_e_rs your group has bee- facing as a resu"t of the un-
certainity surrounding implementing Section 210 of PURPA and
Section- 66-c of the Public Service Law. Please review this
legislation with its accompanying amendment and contact our
office with your opinions on it. Our planning calls for the
introduction of this legislation soon.

PROJECT DESCRIPTION
I "
The proposed Van Natta Water Power Rehabilitation Project is located on the Six Mile
i Creek, immediately downstream of the Giles Street Bridge, in the city of Ithaca, New
_ York.
Historically, water provided power at Van Natta's pumping station from three separate
sources: One source was from the upstream Sixty Foot Dam, where a.24 inch diameter
pipe carried water for 9,400 feet to the pumping station. The second source was from
the Thirty Foot Dam, where a 24 inch diameter pipe passed water for 5,050 feet to the
pumping station. The third origin of water supply for"power was from the Van Natta
Dam located adjacent to the pumping station. "
The proposed project is to rehabilitate and utilize the civil features associated with
the later mentioned source of water supply from the Van Natta Dam.
These project features include an existing dam, intake structure, brick and"concrete
' penstock, turbine/generator room- and a rock lined tunnel tailrace.
The existing dam was constructed of reinforced concrete and was built in 1907. The
dam spans across the creek for a total length of 142 feet, at a spillway length of 115
feet, and at average height of 12 feet.
The existing east abutment of the dam located adjacent to the pumping station served
as an intake to an 8 foot diameter brick lined concrete capped penstock. That existing
penstock runs parallel to the existing building from the intake structure for a distance
of approximately 58. feet. At the end of that brick and concrete penstock is an
existing 5 foot diameter steel penstock, which is supported by an existing concrete
column. That steel penstock has an overall length of 27 feet before entering the side"
of building.
_ Although the steel penstock and generating equipment inside the building have been
removed h t ere is evidence that this penstock,.fed a turbine, which was located in the
lower level of the building and then discharged water into an existing rock lined
f tunnel tailrace, which is located below.
This was one of the several turbines that harnessed the water power within the.
R building. Another turbine/generator which 'was supplied with water from the
upstream Thirty Foot Dam was located on an existing concrete floor approximately
28Y2 feet above the beginning of the rock tunnel tailrace floor. That pump turbine had
a 18%z foot draft tube that extended from the turbine to below the tailwater. The

The proposed project will locate a new turbine/generator room directly below the
existing pump turbine/generator room that was. formerly provided with water from
the upstream Thirty Foot Dam. The new turbine/generator room will be located in an
area at the beginning of the existing rock tunnel tailrace. Flow to the new turbine will
j ! enter through a new trashrack gate structure to be located in front of the existing
concrete intake structure. The water will then pass through the existing brick and
concrete penstock and enter into a new 48 inch diameter steel'penstock, which will be
interfaced into the existing brick concrete penstock. The new 48 inch penstock will
- then turn to enter into the side of the building, where 1t.will then run down inside the
building and connect to the new turbine inlet. A new concrete floor will be required
within the tailrace tunnel to support the new hydro generating equipment.
A portion of the existing ' concrete floor located directly above the new
turbine/generator room, which formerly supported the former hydro _generating
equipment, will be removed to accommodate the new penstock and to provide access
and installation of the new equipment below. The new switchgear and controls will be
located on that level and the transformer will be located on the first floor of the
pumping station.
The new 8.3 KV transmission line will, exit the building near the entrance and run
approximately 90' underground to a riser pole near'the Giles Street Bridge. The new
20' length overhead line will then'be interfaced with the existing utility overhead 8.3
KV transmission line at the bridge.
The proposed project will operate on a "Run of River" mode where all inflow will equal
- outflow. The proposed hydro generating equipment is capable of operating between a. -
flow range of 20 cfs - 100 cfs at average net .head of 56.75 feet at an installed
capacity of 400 kw. When all incoming flow is less than 20 CFS the hydro station
I_ would not be operating and all incoming flow would pass over the spillway and down
the rock steps. When flows are in excess of 100 CFS, these additional flows beyond
100 CFS would pass over the spillway and rock steps.
In addition, during,the months-of March, April, and May, a continuous flow of 9 cfs will
be released over the spillway in order to provide for downstream passage of salmon in
the spring. During the remaining months it is -proposed to release 4 cfs over the
�- spillway during daylight hours, in order to maintain the aesthetic value of the falls.
HYDROLOGY AND HYDRAULICS
t :
The Six Mile Creek originates in the Yellow Barn State Forest, located in the central
area of Tompkins County, New York. The creek flows in a meandering southerly
direction through the Town .of Slaterville Springs, where it then flows in a west-
northwesterly direction through the City of Ithaca to its confluence with Cayuga inlet.
The watershed contributing to the creek is characterized by mostly undeveloped land
consisting of open fields and woodlands. The primary drainage paths are generally flat
(1.5 percent,slope.) However, the adjacent hillsides have steep (9 percent) slopes. The
hills that form the watershed divide are 1,021 to 1,521 feet .above Cayuga Lake's
surface elevation. There are a few small ponds and wetlands in lowland areas of the
watershed.

An outline of the creek's drainage basin on a topographical map was obtained from
f U.S.G.S and can be found in the Appendix . The U.S.G.S. reported that the drainage
area at the Sixty Foot Dam is 45.6 square miles, and 47 square miles at the Thirty
Foot ,Dam. These numbers correspond with. the drainage areas that the Army Corps
developed during their Phase I Dam Inspection Report. Neither of the above agencies
had determined the drainage area for the Van Natta Dam, therefore, interpolation was
'- used to develop a drainage area of 49 square miles for that site.
Presently there are no hydrologic recording stations on the creek or any substantial
. historical flow data. U.S.G.S did measure flow during the summer of 1965, but they
have no other records or knowledge of any existing data.
In order to determine the former and anticipated flows on the creek, flow data from
streams with similar drainage basins were obtained from U.S.G.S.'
As illustrated on the topographical map.in the Appendix, Fall Creek and Cayuga Inlet
are adjacent streams with basins sharing similar topography, geology and weather
conditions. Although percolation and runoff -do vary from basin, to basin due to
evaporation, soil composition and vegetation, the basin's proximities enable a
justifiable comparison.
! I U.S.G.S. has gaging stations on both Fall Creek and.Cayuga Inlet. Fall Creek Gaging
Station is located just upstream of Beebe Lake, with a total drainage area of 126
} square miles. - The Cayuga Inlet gage is located downstream -of Blakslee. Hill. Road,
with a total drainage area of 35.2 square .miles. The period of recorded data for Fall
iE
Creek gage is 1926-1981 and 1938-1980 for Cayuga Inlet.
For the purpose of this study the water. years 1938-1980 from both gaging stations,
were used to develop the flow projections at Six Mile Creek.
The average monthly flows for 42 years at both-gages were multiplied by the drainage
area ratios to reflect the expected flows for the Van Natta site on the Six Mile Creek.
As illustrated from the table in the appendix, these two mean monthly expected flows-
were then averaged together. Although there will be some error in projecting the
flows, it is expected that this averaging method 'will yield values that are within
approximately 15% of the actual flows on the Six Mile Creek. These projected flows
will be used in determining the quantity of inflow.
In January 1982, the City received their Water System Evaluation Report-prepared by
Malcolm Pirnie; Inc. That study reported the existing 24" water main intake at the
Sixty Foot Dam to average 3.58 mgd (5.54 cfs) and a maximum monthly demand of
4.07 mgd (6.29 cfs) for the year 1981. The study projected an average demand for the year 2005 to be 4.18 mgd (6.47 cfs), and a maximum monthly demand of 4.60 mgd (7.1
�- cfs).
Assuming the expected average life of a hydro plant to be 50 years,the projected water
demand .for the City should be included in determining estimated future flows for
hydro power. At Van Natta an overall 9 cfs wad deducted, this deduction is illustrated
on the estimated average monthly flow table in the Appendix.
In addition, a flow duration curve was then developed by adjusting drainage area ratios
from the Fall Creek Flow Data and the Cayuga Inlet Data to the Six Mile Creek and
then averaged. This curve can be found in the Appendix.

GEOLOGICAL RESOURCES
i
The Six Mile Creek watershed area is an important resource in the system of gorges
that have come to be one of Ithaca's most noted features. Formed as a result of
extensive glaciation during. Pleistocene glacial advances, the Six Mile Creek gorge is a
-relatively unspoiled natural area of great visual beauty.
Located downstream of the Van Natta spillway, the water cascades over a series of
natural rock steps for a.distance of approximately 130 feet before entering an existing
pool which is located at the end of the pumping station building and at the base of the
last rock step. These rock.ledge steps average in height of approximately four feet
and their seams run perpendicular and parallel to the spillway.
These natural rock steps form the Creek's channel which gradually reduce in width of
' 34 feet at the base of the spillway to a width of 13 feet before diverting the flow into
_ the pool.
Steep rock cliffs form the.,Creek's embankments for a distance 'of approximately 340
feet downstream of the pumping station. Boulders and rough cut sections of ledge are
intermittently dispersed in this section of the Creek. An exception to the cliffs is a
' tongue of exposed rock which protrudes out into the Creek, and is located across from
j and immediately downstream of the pumping station and is referred to by local
residents as the Old Indian Campground.
RECREATION
Several Citizen Committees currently share responsibility for maintaining trails,
parking and picnic areas on Six Mile Creek in the vicinity of Van Natta's Dam.
Though readily accessible to both city and town residents - located a few blocks from
the downtown area and wedged between two heavily populated residential
neighborhoods - use of the Six Mile Creek watershed for the city water supply
necessitates strict regulation of recreational use of the area. Many activities such as
swimming, boating, camping and ice skating are prohibited. However, more passive
recreational uses such as walking and nature study are permitted in designated areas;
particularly around the Van Natta's Dam site.
Swimming: Although there are laws forbidding trespassing and swimming within this
! creek system, swimming is still a common activity, particularly in the impoundment
formed by Thirty Foot Dam. Several youths have been seriously injured while diving
from the surrounding cliffs, and local police have made numerous arrests in an effort
to discourage these activities.
Hiking: Narrow paths may be found along the entire reach of Six Mile Creek from
Sixty Foot Dam to Van Natta's Dam. These paths provide excellent hiking
1 opportunities fo
r or recreation and nature observation. The abundant natural attributes
combined with the flowing water of the Creek, make the gorge very popular with local
naturalists.

t the watershed. The development of a Master Plan has been proposed for the gorge,
and a Gorge Ranger has been hired to monitor use of the area. Plans are being
developed to improve passive recreation in the Six Mile Creek gorge. These include
the following:
1. Proposed designation of Six Mile Creek as a Critical Environmental Area
pursuant to the State Environmental Quality Review Act.

`- 2. Trail mapping by the City of Ithaca
3. Development of a wildflower guide for public distribution
4. Development of a brochure on use of the gorge, highlighting do's and don'ts
5. Lengthening the season of wildflower interest by introducing summer and
autumn wildflowers
6. Establishment of a "Get Well Walk" allowing use of part of the trail system
- for recuperation
7. Development of a long term plan for'.care and interpretation of the
wildflower preserve
FISH AND WILDLIFE
The stream and reservoir habitat above Van Natta's Dam is classed as a mixed
coldwater/warMwater fishery. The New York State D.E.C. operates its fry stocking
program for landlocked salmon in these upstream .reaches. These salmon grow to
- smolts in upperstream and migrate downstream during spring and early summer,,
passing over the series of dams on Six Mile Creek to arrive at Cayuga Lake where they
i
grow to maturity.
The upper reservoir area supports mostly warmwater fish species such as brown
bullhead, largemouth bass, a variety of centrarchids and an occasional brown trout.
These species are also likely to'be found in the Thirty Foot Dam reservoir and in the
Creek: The area below Van Natta's Dam serves as spawning habitat for rainbow trout
and smallmouth bass.
PAGE 14
I
EXHIBIT E
ENVIRONMENTAL
i
Migration upstream occurs during the spring of each year. Upstream migration beyond
the Van Natta's Dam is prevented, due to the falls and the absence of ,.fish passage
facilities at the Dam.
! The following is a list of most resident fish species likely to be found in Six Mile Creek .
between Sixty Foot Dam reservoir furthest upstream, and the plunge pool below Van
Natta's Dam. This list is based on D.E.C. fish surveys in 1955 and 1960.

The high degree of isolation-found in the Six Mile Creek gorge, due to its steep rock
walls, provides excellent wildlife habitat. This is .unique, considering the urban
residential character of the surrounding area. There are numerous bird species which
are resident of migratory transients to the gorge. These include robins, jays, grackles,
tanagers, goldfinches, orioles, a variety of sparrows and woodpeckers, crows, hawks
and owls. Ducks, herons, and egrets may also be found in some section of the creek
- and reservoirs. Mammalian forest and field species are also common to the area.
Signs of white-tail deer are common. Raccoon, skunk, muskrat, mustelids and a
variety of mice and other rodents are also likely to be found.
The U.S. Fish and Wildlife Service reports that although there may be occasional
transient individuals present in the Six Mile Creek System, no federally listed or
proposed endangered or threatened species are known to exist in the project area at
this time. No critical habitats are present, though the area around and below Van
Natta's Dam has been designated as a nature area by the City.
VEGETATIVE COVER
- - A great variety of wildflower and hardwood species exist in Six Mile, Creek in .the
vicinity of the Van Natta's Dam. The Creek System supports a wildflower population
that is believed to exhibit the greatest species diversity of any single area in the state.
In 1970, the area was designated a wildflower preserve by the city and in 197, the
Circle Greenway Committee was established to delineate paths and provide tours in
- the vicinities of intense wildflower growth.
The largest concentrations of wildflowers may be found between Thirty Foot Dam and
Giles'Street, located near Van Natta's bam. The Indian campground, a high knoll
directly across and slightly downstream of the Van Natta's Dam Pumphouse facility, is
characterized by acid soils and the species which grow is such soil.

While no list of native floral species has ever been developed for the gorge, Flora of
the Cayuga Lake Basin, a book published in 1920, makes many references to Six Mile
Creek and provides an idea of what species existed in the area historically. The City
of Ithaca has recently contracted the services of Dr. William Dress, professor emeritus
of the Cornell University Horitorium, to develop a species accountant. This study
effort is currently underway.
WATER QUALITY AND QUANTITY
The Six Mile Creek watershed area is the source of water supply for the City of
Ithaca. The water is treated subsequent to filtering at the city's Water Filtration
Plant to bring it up to State Health Department, E.P.A., and D.E.C. quality standards
for drinking. The maximum capacity of the filtering system is seven million gallons of
water per day. Presently, the average load drawn through the system (based on daily
demand) is approximately 4.7 million gallons per day.
HISTORICAL AND ARCHAEOLOGICAL RESOURCES
The Indian Winter Campground, a tongue of exposed. rock across the stream from the
old powerhouse/pumphouse building, extends into Six Mile Creek immediately below
the Van Natta's Dam. The campground is locally recognized as the. historical winter
dwelling place of the designated nature area.
The abandoned Van Natta's pumping station is located on Six Mile Creek at Giles
Street near the city's Water Treatment Plant. The pump station.was constructed in
1893, by a private water supplier. During the year 1904, the City of Ithaca.acquired
ownership of the water system by condemnation. The station -housed ten pumps in a
wood frame structure with a masonry veneer. Other additions were made to this
structure.
In 190, new higher powered pumping machinery was bought and installed at Van Natta's.
to enable pumping, in greater-quantities, to the hills, and in, 19070 a new dam was built
- at Van Natta.
To acquire more storage capacity and save power, the 60 foot dam reservoir was
constructed 1 h miles.upstream of Van Natta's in 1911. A 24 inch pipe line was run to
the filtration plant, and hydraulic turbines were installed in Van Natta's Pumping
Station to make use of this water power for pumping filtered water. Three of the
pumps were used as emergency standby to deliver raw water through a 20 inch main to
the filtration plant. Seven pumps delivered water to the East Ithaca and Mitchell
Street Service Areas. All-pumps have since been removed. Though long abandoned,
the Van Natta's structure appears to be dry and sound. The proposed rehabilitation of
- the generating facility would utilize much of the existing civil works. Located in,the
appendix is a copy of the history of Ithaca's water and sewer systems.

ENVIRONMENTAL
EXPECTED ENVIRONMENTAL IMPACTS FROM THE CONSTRUCTION AND
AND OPERATION OF THE PROJECT:
The construction and operation of the project as proposed should have negligible
environmental impacts upon the surrounding area. Approved "porta-dams, will be
installed at the headrace and tailrace to isolate construction activities from the river.
Exterior construction will be limited to the intake rehabilitation work, interfacing and
installing new penstock and installation and interconnection of the new transmission line.
The existing pumphouse will be utilized so that other construction will be limited to
interior work. There will be no installation of flashboards. Therefore, water levels in
the impoundment will be unaffected by-.the impoundment or upstream of the project.
Removal of any old generating equipment of potential "historical interest will be
�- recorded, and reported to the New York Historic Preservation Commission'.
Operating as a run-of-the-river project, negligible storage capacity of the
impoundment area will be utilized. There will be no water level fluctuations and,
through constant recirculation of the impoundment,no measurable increases in water
temperature are expected. Also, there will be no pollutant discharges from the
facility so that eutrophication will not be enhanced as a result of project operations,
and no releases of.toxic substances will occur.
The lower reaches of the Six Mile Creek are periodically ponded during the summer
months, due to reduced flows and the municipal water damands of the City. Removal
of water at the upstream Sixty Foot Dam eliminates flow over the dam and `
downstream to the Thirty Foot Dam and Van Natta's Dam. The impact of this ponding
t--
to aquatic habitat is not known, but must be significant. The critical-flow period for
this section of Six Mile Creek occurs during the downstream migration of Atlantic
salmon smolts. Sufficient flow over the dams is required at this time to pass the
smolts over the dam without injury. The majority of the salmon migration takes place
during the months of March,- April, and "May. Therefore the migration is usually
completed before flow is eliminated over the Sixty Foot Dam.
-- - The New York D.E.C. minimum flow recommendation for the Ithaca Falls
Hydroelectric Project, located nearby on Fall Creek, requires a continuous flow of 16
cfs for downstream fish passage until studies of injuries or mortalities with passage
over Ithaca Falls can be determined at this flow. Mitigative measures, such as
notching the dam above the,plunge pool or a higher minimum flow, may be required if
mortalities are excessive.
It was learned during the preliminary consultation with the New York-D.E.C.-that the
85% exceedence value from the flow duration curve can beused as an estimate for
minimum flows. This flow equals to 9 cfs for the Six Mile Creek. Although the actual
minimum flow requirement may be more or less depending upon New York D.E.C:s
determination of specific needs of the stream system, this flow of 9 cfs was utilized.
PAGE 17
EXHIBIT E
ENVIRONMENTAL
The major fisheries concern, expressed by both the U.S. Fish and Wildlife Service and
the New York D.E.C. Division of Fish and Wildlife, have been the maintenance of
stream habitat and the provision of'sufficient flows over the three dams in the project
area to. permit downstream passage of Atlantic salmon smolts without injury. -The
New york D.E.C. salmon stocking program on Six Mile Creek is subject to fluctuations
in the availability of fry from year to year, therefore, the stocking of fry and
subsequently the migration of smolts may be intermittent in future years. However, it
is expected that mitigative measures for hydroelectric development will be required
on an annual basis to accommodate all future stocking efforts by D.E.C. The two
major fisheries constraints affecting hydroelectric development on Six Mile Creek are;
1) the entrainment of salmon smolts and resident fish by intake structures and the
potential turbine related mortalities that may result, and 2) the provision of sufficient
minimum flow for habitat maintenance and safe passage of smolts over .the three
dams. These two constraints will be discussed separately.
Entrainment: Salmonid mortalities related to turbine passage have been researched
under a number of hydraulic head, flow, and equipment variations. However,
preconstruction mortality estimates are difficult to assess, due to the variability of
site specific conditions. It is recommended where practical, that in addition to
trashracks, a screening device be installed at the intake to prevent entrainment of fish
through the turbines.' The City municipal water intake at the Sixty Foot Dam
presently has a 2" mesh,screen for this purpose. Some fish still succeed in entering the
intake and'are trapped at the water treatment plant. Each of the three alternatives
under study will require plans for installation and maintenance of fish screens at the
intakes, with a maximum mesh size of 211, and a potential 1" mesh requirement if the
D.E.C. determines the need for a smaller mesh size.
Maintenance Flows: An intermediate minimum flow will be released in order to
provide for downstream passage of salmon in the spring, and also to provide flows to
the Van Natta Falls for aesthetics. The recommended minimum flow of 9 cfs would be
required for approximately three months of the year, 24 hours/day to provide safe
passage for salmon over the falls.
The existing rock lined .tailrace tunnel exits the pumping station at a location
immediately adjacent to the last natural rock step downstream of the spillway.
Therefore, during normal operating conditions, the water- surface elevation- at the
existing pool, located at the base of the last rock step will remain at its natural
elevation. It is therefore unlikely that 9 cfs would be required year round for habitat
maintenance, since there would be negligible loss of aquatic habitat. In addition, in
order to maintain the aesthetic value of the falls when viewed from the Indian Winter
Campground, a lesser minimum flow of 4 cfs could be passed over the falls during
daylight hours for this purpose.

Dear Sir:
We have reviewed the material submitted with respect to the Van Latta
Water Power Rehabilitation Project.
This office recognizes the limitations for development of recreational
opportunity because of the characteristics of the gorge and adjacent land
areas. We do however encourage the developnmt of a master plan for the
gorge and the proposed improvement of passive recreation as called for in
your report, compatible with the safe and efficient operation of the
facility.

Dear iir.. Halliwell:
This is in response to your letter of July 31 regarding the Van Nattas
Water Power Rehabilitation Project, Six Mile Creek, Ithaca, New York.
On October 12, 1982 the Department of- the Interior submitted review
comments (copy attached) to FERC on an earlier proposal for. this site.
Your Project Description leaves some questions unresolved regarding
the expressed concerns.
There is no indication that the concerns regarding fish and wildlife
resources have been addressed. Similarly, it remains uncertain as to
what historical/archeological resources may be involved or if the
State Historic Preservation Officer has been consulted. More definition
as to the assured recreational use of the site should be included.
Sincerely,
William Patterson

Dear Mr. Halliwell:
This responds to your July 31, 1984, letter requesting review and comments on
the Van Natta Hydroeletric Project located on Six Mile Creek, Ithaca, New
York.
This response provides technical assistance only and as such does not
constitute the report of the Secretary of the Interior within the meaning of
Section 2(b) of the Fish and Wildlife Coordination Act (48 Stat. 401, as
amended; 16 U.S.C. 661 et seq.). Nor should our input at this stage of your
planning process be construed as sufficient to accompany any request for
license that you may submit for this project to the Federal Energy .Regulatory
Commission (FERC).
The applicant should be aware that the downstream passage of Atlantic salmon
smolts must be provided for at the Van Natta Hydroelectric Project site.
Planning for fish passage should be initiated with the New York State
Department of Environmental Conservation (NYSDEC) and the U.S. Fish and
Wildlife Service (FWS) during the early planning stage and a plan for fish
passage be included in your draft Exhibit E.
The following items will serve to identify other information needs and major
generic concerns regarding hydroelectric development. We would recommend that
these items be addressed in Exhibits A and E of any application that you may
submit to the Commission for the Van Natta Project. This information will
permit us to adequately assess your project and provide the appropriate
recommendations to the Commission. Certain of these items may have already
received adequate treatment in your preliminary project description.
1. A detailed map with proper land description of the entire project area
by township, range, and section as well as by State, County, river, rivermile
and closest town. The specific location of all project facilities including
roads, transmission lines, and any other appurtenant facilities should be
shown.
34
2. A general engineering design of the proposed project. Any planned
stream diversion through a canal or penstock should be fully described.
3. A brief summary of the proposed project's mode of operation including
the minimum and maximum flows that can be used to generate power. Will water
be stored behind the dam for peaking power? We are especially concerned with:
potential impacts associated with this type of operation. When inflow falls
below the minimum, will water be spilled over the dam or diverted through a
penstock or power canal?
4. Stream flow and water regime information .including drainage area
maximum, minimum, average annual, and MA7CD10 flows, and mean daily flow
figures illustrating the annual and monthly flow duration curves at the
proposed point of diversion or impoundment with the location of the stream
gauging station(s) used and a description of the method used to generate the
streamflow data provided.
5. An assessment of the species of fish and other aquatic resources
present above and below- your dam including relative abundance, if available, '
and documentation of the historical occurrence of anadromous fishes in the
river on which your project is located. The NYSDEC should be contacted for
this information. Such requests should be directed to Mr. Murdock MacKenzie,
Division of Regulatory Affairs, New York State Department of Environmental.
Conservation, 50 Wolf Read, Albany, New York 12233.
6. An assessment of the factors, if any, that limit water quality in the
project area,. Will the operation of your project impair the ability of the
impoundment and river to dilute agricultural, municipal, and industrial wastes?
Will sufficient flow be maintained at all times to assure the adequate
assimilation of these effluents? If water quality may be impaired, how will
this affect the existing fishery resources?.
7. A brief analysis of the anticipated change in streamflow,
temperatures, and/or oxygen regime of the river that may be precipitated by
project operation. Will there be significant water level fluctuations
(drawdowns) in the impoundment, and if so, when and to what extent will they
occur?
B. A brief analysis of the effects of project operation on existing
aquatic and fishery resources, including spawning and nursery habitat, above
and below your dam or the proposed point of diversion.
9. Identify and evaluate any measures you propose to employ to avoid,
offset, and/or reduce adverse project-caused impacts on existing fish and
wildlife resources.
If the proposed Van Natta Project operates in a run-of-the-river mode and does
- not alter existing reservoir surface elevations, downstream flows, temperature
profiles, and oxygen regimes, then impacts on fish and wildlife resources would
be minimized.
2 35
We appreciate this opportunity to provide input 'at this stage of your planning
process. We look forward to the opportunity to review this project's
environmental report and application prior to- its submission to the -Commission.
It is our, understanding that the Commisssion wants FWS comments on a project's
environmental report to be included in its application. Also, supplying us
with an advanced copy of this project's final application will expedite our
final _review of this project once its application has been accepted by the
C =ission.
Should you have any questions, please do not hesitate to contact Mr. Lou Rzepka
