LEVEL OF CITY DISCRETION IN DECISION-MAKING:
The City’s discretion
in approving or denying a site plan is limited to whether or not the proposed project
complies with Zoning Ordinance requirements. If it meets these standards, the City must
then approve the site plan. This is a quasi-judicial decision.
The City’s discretion in approving or denying a variance is limited to whether or not the
proposed project meets the standards in the Zoning Ordinance for variance. The City has a
relatively high level of discretion with a variance because the burden of proof is on the applicant
to show that they meet the standards in the ordinance.

The City has limited discretion in approving or denying conditional use permits, based on
whether or not the proposal meets the conditional use permit standards outlined in the Zoning
Ordinance. If the City finds that all the applicable conditional use permit standards are met, the
permit must be approved. This is a quasi-judicial decision.
PROPOSAL/SUMMARY
Minnesota Valley
Electric Cooperative
(MVEC) is
proposing to
construct a local
115-kilovolt electric
distribution
substation on
property located east
of the Gedney Pickle
plant, north of
Stoughton Avenue
and Xcel Electric
Substation, south of
Flying Cloud Drive,
and east of a
cemetery located in
the City of Chaska.
The site is zoned
Industrial Office
Park-IOP.
Xcel Energy Electrical
Towers are located in the
City of Chaska, south of the
proposed MVEC site. This
entire substation was
purchased by MVEC and
will be completely
dismantled and removed.
The existing driveway
serving the Xcel Electrical
Towers will be extended to
the north to serve the
proposed MVEC substation.
Any transmission line over
100 kilovolts requires an
Environmental Assessment

(EA). The EA contains information on the human and environmental impacts of the proposed
project and addresses methods to mitigate such impacts. The applicant has prepared an
environmental assessment (EA) that reviews the proposal for the site as well as the surrounding
area. Staff has reviewed the EA that is complete and is recommending approval of a resolution
Negative Declaration
of of the Need for an Environmental Impact Statement for the Minnesota
Valley Electric Substation site.
The applicant is requesting site plan approval for the construction of an electric substation. The
substation will consist of a low profile modular facility that will be screened by a concrete tip-up
wall on three sides and a chain link fence along the east side of the site. The wall is proposed to
have a height of 10 feet. Commercial or industrial fences over eight feet require a conditional use
permit. This fence/wall is for security as well as aesthetic purposes. Staff is recommending
approval of the conditional use permit to allow a 10-foot wall.
The zoning ordinance allows electric substations in the IOP district as a Conditional Use Permit.
There are special requirements for an electric substation, one of which is the size of the property.
The ordinance requires a minimum of 5 acres. The applicant is proposing to build the facility on a
2.35 acre parcel. The second requirement stipulates that substations maintain a 500-foot setback
from single-family residences. The subject site is located approximately 200 feet from a mobile
home park located south of Stoughton Avenue. The applicant is removing an existing substation
(Xcel substation) and replacing it with the proposed substation which will maintain a larger
distance from these homes. The ordinance requires the site to be served via a collector or major
arterial street as designated in the comprehensive plan. Stoughton Avenue is not classified as
either, but functions as a collector. For this use, the current location is most ideal and causes the
least disturbance and impact to the area. Staff is recommending approval of the variance and the
conditional use permit to allow the electric substation.
Staff is recommending approval of the site plan, conditional use permit with variances, and
resolution of Negative Declaration of the need for an Environmental Impact Statement for the
Minnesota Valley Electric Substation site with conditions outlined in the staff report.
BACKGROUND
On March 14, 2005, the City Council approved an ordinance amendment regulating and defining
Electric Substations.
On November 15, 2005, the Planning Commission conducted a Public Hearing to determine
the scope of an Environmental Assessment, request for a Conditional Use Permit with
variances and Site Plan Review application to construct a local electric distribution substation
on property zoned Industrial Office Park, Minnesota Valley Electric – Planning Case
No. 05-30. The Planning Commission recommended approval of the Environmental
Assessment Scoping, directed staff to prepare the EA consistent with the scoping, and tabled
further proceedings on the Conditional Use Permit, Site Plan, and Variance until such time as
the EA is completed and submitted to the Planning Commission.

GENERAL SITE PLAN/ARCHITECTURE
The proposed electric substation will be located on approximately 2.35 acres. Staff has been
working with the applicant for over a year to bring forth the best development alternative. Staff
and the applicant both agreed that the
substation needed to be screened from
views. Enclosing the utility structures
inside a building was not an option. The
applicant proposed to build a tip-up
decorative concrete fence on three sides of
the substation and a chain link fence on the
easterly side. Staff agreed that this
alternative was acceptable.
The wall shown in the photo to the right is
an example of the type of wall that is
proposed to be used along the parameter of
the substation.
There is a row of existing mature
evergreens that will screen the site
from the east. Additional
landscaping will be added along the
entire fence to break up the wall
visually and add some interest.
This operation will generate minimal
traffic. Consequently there will be
an area for a maintenance truck to
park and turn around.
There is no trash enclosure proposed
with this development.
ARCHITECTURAL COMPLIANCE
Typically, staff prepares an architectural compliance analysis of any proposed development. The
analyses addresses issues such as size, portion and placement, entries, articulation, material and
detail, color, height and roof design, facade transparency, loading areas, refuse areas, etc. This
proposal does not contain a typical building; therefore there is no analysis required. The
applicant has made a considerable effort to screen the electric substation. The applicant is also
proposing to take down the existing Xcel Energy electric substation which will improve the
appearance of the area considerably.

SITE PLAN FINDINGS
In evaluating a site plan and building plan, the City shall consider the development's compliance
with the following:
(1) Consistency with the elements and objectives of the city's development guides,
including the comprehensive plan, official road mapping, and other plans that
may be adopted;
(2) Consistency with this division;
(3) Preservation of the site in its natural state to the extent practicable by minimizing
tree and soil removal and designing grade changes to be in keeping with the
general appearance of the neighboring developed or developing areas;
(4) Creation of a harmonious relationship of building and open space with natural site
features and with existing and future buildings having a visual relationship to the
development;
(5) Creation of functional and harmonious design for structures and site features, with
special attention to the following:
a. An internal sense of order for the buildings and use on the site and
provision of a desirable environment for occupants, visitors and general
community;
b. The amount and location of open space and landscaping;
c. Materials, textures, colors and details of construction as an expression of
the design concept and the compatibility of the same with adjacent and
neighboring structures and uses; and
d. Vehicular and pedestrian circulation, including walkways, interior drives
and parking in terms of location and number of access points to the public
streets, width of interior drives and access points, general interior
circulation, separation of pedestrian and vehicular traffic and arrangement
and amount of parking.
(6) Protection of adjacent and neighboring properties through reasonable provision
for surface water drainage, sound and sight buffers, preservation of views, light
and air and those aspects of design not adequately covered by other regulations
which may have substantial effects on neighboring land uses.
Finding:
The proposed development is consistent with the city's comprehensive plan
and the zoning ordinance if the variances to the conditional use permit were approved.
The site design is compatible with the surrounding development. It is functional and will

WETLANDS
Upon review of the plans, it is concluded that there are no wetlands on this site.
STORM WATER, GRADING, AND EROSION CONTROL
The northern portion of the property currently drains to the north. The central portion drains
towards the depression located in the middle of the site. The southern portion of the site drains
to the south. The 155’ x 200’ substation pad will sheet drain to the west. The plans must

shows how the pad facilitates drainage under the decorative wall.
The proposed grading plan identifies shallow depressions on the north and south ends of the
property and an infiltration basin on the west side of the property. The southern depression will
overflow to the west and the northern depression will overflow to the north. The infiltration
basin storage capacity exceeds the 100-year runoff volume. Based on the Carver County soils
data, the infiltration basin will infiltrate within 60 hours; the PCA recommends infiltration within
72 hours.
The 100-year post-development discharge rate and volume to the north will not increase. The
100-year post-development discharge rate to the southwest will decrease and the post-
development discharge volume will increase slightly.
The runoff to the infiltration basin may carry particulate matter from the gravel substation pad.
Staff recommends that annual maintenance be performed on the infiltration basin so that it will
function as modeled.
LANDSCAPING
Minimum requirements for landscaping include bufferyard plantings along property lines. The

Due to the presence of overhead power lines on the site, only understory trees are recommended
for planting. The totals for overstory species should be transferred to the understory totals. The
applicant does not meet minimum ordinance requirements for the buffer yard plantings. Staff
recommends that the applicant increase planting totals in order to meet ordinance requirements.
LIGHTING
The applicant is not showing any light fixtures on the plans. Detailed lighting plans shall be
submitted including photometrics and type of light fixture. The ordinance requires no more than
0.5 foot candle at the property line. Only downcast shielded fixtures are allowed as required by
ordinance. Any security (motion detection) lighting should also be shown.
CONDITIONAL USE PERMIT
ANALYSIS
The applicant is requesting a conditional use permit for the construction of an electric substation and
a 10-foot high fence/wall, in the Industrial Office Park District. The substation will better serve the
residents of Chanhassen and the surrounding area. Chanhassen has experienced rapid growth and
the completion of Highway 212 is anticipated to significantly drive new growth into the area.
FINDINGS
The Planning Commission shall recommend a conditional use permit and the council shall issue
such conditional use permits only if it finds that such use at the proposed location:
1. Will not be detrimental to or damage the public health, safety, comfort, convenience or general
welfare of the neighborhood of the city.
Finding:
The substation will provide a basic utility to the residents of Chanhassen and the
surrounding area. The wall will provide screening and act as a security fence.

Will be served adequately by facilities and services provided by the persons
responsible for the establishment of the proposed use.
6. Will not create excessive requirements for public facilities and services and will not be
detrimental to the economic welfare of the community.
Finding:
Will not create excessive requirements for public facilities and services and will not
be detrimental to the economic welfare of the community. It will provide a
necessary utility.
7. Will not involve uses, activities, processes, materials, equipment and condition of operation that
will be detrimental to any persons, property or the general welfare because of excessive
production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash.

an existing substation across the street from the mobile home which
MVEC has purchased and is proposing to dismantle and remove. The new
substation will maintain a larger setback from the mobile homes than the
existing substation.
g. A summary of current research regarding the health effects of EMF levels,
conducted by health and scientific professionals, including those who do and do
not receive utility sponsorship;
Finding:
The applicant provided the following information:
Electric and Magnetic Fields
Questions often arise about electric and magnetic fields (EMF), which are invisible
lines of force that surround any electrical device. The term EMF refers to electric
and magnetic fields that are coupled together such as in high frequency radiating
fields. For lower frequencies, such as for power lines, EMF should be separated into
electric fields and magnetic fields. Transmission lines operate at a frequency of
60 hertz (cycles per second), which is in the non-ionizing portion of the
electromagnetic frequency spectrum. Fields are considered ionizing when they cause
electrons to eject from their orbits around a normal atom. This will typically occur
16 22
with frequencies in the range of 10to 10 hertz.
Magnetic fields result from the flow of electricity (current) in the transmission line.
The intensity of the magnetic field is related to the current flow through the
conductors. The magnetic field associated with the transmission line surrounds the
conductor and rapidly decreases with the distance from the conductor. The value of
the magnetic field density is expressed in the unit of gauss or milligauss.
The most recent and exhaustive studies of the health effects from power frequency
fields conclude that the evidence of health risk is weak. Some of these studies are
listed below:

For this project, the overall EMF impact will not change at the property lines. With
the retirement of the Xcel Energy East Chaska Switching Station, the overall EMF
readings on the property are anticipated to decrease closer to the road. In the area of
the new substation, the EMF will increase slightly, with new transformer and
distribution facilities.
h. Provide EMF levels under maximum and average anticipated loading at the base
of the utility poles, underneath the wires between the poles, at ground level above
underground wires, at the edge of the property line, at the edge of the closest
habitable building, and at the point above ground where there would be the
greatest EMF level;
Finding:
See sheet labeled “Estimated EMF Levels-Chanhassen Substation”.
i. Reasonable and prudent measures to minimize EMF levels along all alternative
routes;
Finding:
The applicant is removing an existing substation that is located closer to a
residential area and building a new one that will have less impact on the
residential area and will be located further from the residential area.
j. Depictions of the views of the proposed facility, if aboveground, from at least two
directions selected by city staff.
Finding:

VARIANCE
ANALYSIS
Under the conditional use requirements for a substation, there are three requirements that the
proposed development does not meet. First, the ordinance requires a minimum of a 5-acre parcel.
The proposal is showing 2.35 acres. The second deals with distance from residential areas. The
ordinance requires a 500 foot setback. There is a residential neighborhood located 200 feet from the
proposed site. Third, the ordinance requires the facility to be accessed off of a collector or arterial
street. The site will be accessed off of Stoughton Avenue, which is not a collector or an arterial.
FINDINGS
The Planning Commission shall not grant a variance unless they find the following facts:
a. That the literal enforcement of this chapter would cause undue hardship. Undue hardship
means that the property cannot be put to reasonable use because of its size, physical
surroundings, shape or topography. Reasonable use includes a use made by a majority of
comparable property within 500 feet of it. The intent of this provision is not to allow a
proliferation of variances but to recognize that and develop neighborhoods where pre-
existing standards exist. Variances that blend with these pre-existing standards without
departing downward from them, meet this criteria.
* The applicant has been able to locate a site that will cause minimal disruption to
neighboring properties, reduce electromagnetic fields impacting adjacent residential
areas and improving the aesthetics of the area. The site does not meet the distance,
lot area, and street designation requirements. It is increasing its setback from
neighboring residential properties by removing the existing Xcel energy site. The
2.35 acres are adequate to accommodate the needs of the proposed facility and the
access issue. Staff discouraged the applicant from accessing the site off of Highway
212. The existing access point off of Stoughton Avenue is adequate. In looking at
the area within 500 feet, the Xcel energy site is located on a .5 acre parcel, is located
less than 150 feet from the residential neighborhood to the south, and gains its access
off of Stoughton Avenue.
b. The conditions upon which a petition for a variance is based are not applicable, generally, to
other property within the same zoning classification.
* The conditions upon which this petition for a variance is based are not applicable
generally to other properties within the same zoning classification.
c. The purpose of the variation is not based upon a desire to increase the value or income
potential of the parcel of land.
* The purpose of this variation is not based upon a desire to increase the value or
income potential of the parcel, but actually is to provide a service for the residents of
Chanhassen and the surrounding area.
Minnesota Valley Electric Substation
Planning Case No.05-30
January 3, 2006
Page 13
d. The alleged difficulty or hardship is not a self-created hardship.
* The difficulty or hardship is not self-created.
e. The granting of the variance will not be detrimental to the public welfare or injurious to
other land or improvements in the neighborhood in which the parcel is located.
* Granting of the variance will not be detrimental to the public welfare or injurious to
other land or improvements in the neighborhood in which the parcel of land is
located.
f. The proposed variation will not impair an adequate supply of light and air to adjacent
property or substantially increase the congestion of the public streets or increases the danger
of fire or endanger the public safety or substantially diminish or impair property values
within the neighborhood.
* The proposed variance will not impair an adequate supply of light and air to adjacent
property or substantially increase the congestion of the public streets.
Staff is recommending approval of this variance based upon the findings listed above.

(10) Will be aesthetically compatible with the area.
(11) Will not depreciate surrounding property values.
(12) Will meet standards prescribed for certain uses as provided in this article.
6. Section 20-58:
(1) That the literal enforcement of this chapter would cause undue hardship. Undue
hardship means that the property cannot be put to reasonable use because of its
size, physical surroundings, shape or topography. Reasonable use includes a use
made by a majority of comparable property within 500 feet of it. The intent of
this provision is not to allow a proliferation of variances but to recognize that
and develop neighborhoods where pre-existing standards exist. Variances that
blend with these pre-existing standards without departing downward from them,
meet this criteria.
(2) The conditions upon which a petition for a variance is based are not applicable,
generally, to other property within the same zoning classification.
(3) The purpose of the variation is not based upon a desire to increase the value or
income potential of the parcel of land.
(4) The alleged difficulty or hardship is not a self-created hardship.
(5) The granting of the variance will not be detrimental to the public welfare or
injurious to other land or improvements in the neighborhood in which the parcel
is located.
(6) The proposed variation will not impair an adequate supply of light and air to
adjacent property or substantially increase the congestion of the public streets or
increases the danger of fire or endanger the public safety or substantially
diminish or impair property values within the neighborhood.

MINNESOTA VALLEY ELECTRIC COOPRA TIVE
Findings of Fact Regarding
Decision on Need for Environmental Impact Statement
I. PROJECT DESCRIPTION
Great River Energy (GRE), located in Elk River, MN, provides generation and
transmission to 28 member cooperatives in Minnesota. GRE and one of its cooperatives,
Minnesota Valley Electric Cooperative (MVEC), are planning to construct a new
substation and high voltage transmission line tap in Chanhassen, Carver County,
Minnesota.
The new substation and tap will be located on a 2.9 - acre site east of Audubon Road and
north of Stoughton A venue in an industrial area adjacent to the MA Gedney Plant in
Chanhassen, Section 3, T115N, R23W, Chaska Township, Carver County. The site
includes property previously owned by Xcel Energy. The new single circuit 115 kV
transmission line will tap an existing 115 kV transmission line (owned by and operated
by Xcel Energy) just northeast of the proposed substation site
The proposed project includes three primary components:
+ MVEC plans to construct a new 115/12.5 kilovolt (kV) substation to be named the
Chanhassen Substation. The substation site will be owned by MVEC and all distribution
facilities will be constructed, operated and maintained by MVEC.
+ GRE proposes to construct, own, and operate approximately 80 feet of 115 kV
transmission line to energize the new substation (Figure 1-2). The line will be a single
circuit design and will tap an existing 115 kV transmission line that is owned and
operated by Xcel Energy. GRE will also own transmission switching facilities located in
the substation.
+ The Xcel Energy East Chaska Switching Station will be removed.
II. REASONS FOR ENVIRONMENTAL REVIEW
This project falls under the State of Minnesota's Power Plant Siting Act, (Minnesota Statutes ~
116C.51-.69 and Minnesota Rules Chapter 4400) for transmission projects over 100 kV and
requires a permit from the Minnesota Public Utilities Commission (Commission). However, for
eligible projects, a utility may apply to the local unit of government that has jurisdiction over the
project for approval instead of applying to the Commission (Minn. Rules pt. 4400.5000). This
proposed 115 kV substation project is eligible for local review.
III. ENVIRONMENTAL REVIEW PROCESS
The Minnesota Valley Elecrric EA was submitted to the Environmental Quality Board on
December 22,2005. The EA W Notice of Availability was published in the January 2,2006 issue
of the Minnesota EOB Monitor. Copies of the EA W were mailed to all of the agencies and
organizations on the EQB official EA distribution list. The lO-day comment period ended on

Project Goal and Need
Minnesota Valley Electric Cooperative (MVEC) provides electric energy to a large portion of Chanhassen and the
surrounding areas, as designated by the Minnesota Public Utilities Commission. The area has experienced rapid
growth in recent years, and completion of the State Highway 312 project is anticipated to significantly drive more new
growth until land use is saturated.
The Substation
A technical analysis of the transmission system identified the need for a new electrical distribution substation site
within the focused area. This analysis considered the presence of existing distribution feeders and transmission lines
as well as existing and future load projections. A location within an underutilized industrial area adjacent to the MA
Gedney Plant on Stoughton Avenue (Section 3, T115N, R23W) , situated directly under existing transmission lines,
was found to be most conducive to the current and future electrical needs of the area. The substation proposed is a
low profile, modular facility that would be proposed with concrete tip-up type walls on three of the four sides. The new
proposed installation will provide considerably more system growth potential, improve MVEC system reliability, and
provide some backup capabilities to both the Bluff Creek and Chaska substations under emergency conditions.
Transmission
Existing transmission lines cross the area near the proposed substation location and include voltages of 69 kV, 115 kV
and 230 kV. MVEC would utilize the 115 kV transmission line (owned by Xcel Energy) in partnership with Great River
Energy (GRE), who would tap the transmission line (one span) and bring it into the substation. Minimal alterations to
the existing transmission system would be required.
Permitting and Scheduling
MVEC and GRE are applying for necessary permits from the City of Chanhassen and will assist in the preparation of
the required environmental assessment. The project will operate at the nominal voltage of 115 kV and is regulated
under the Power Plant Siting Act. A provision of this law allows the utility to seek local approval. Because this is a
local load serving project, GRE and MVEC have elected to seek local approval.

APPLICATION FOR CONDITIONAL USE PERMIT
Chanhassen MN
For the Chanhassen Substation
By
The Minnesota Valley Electric Cooperative
The Minnesota Valley Electric Cooperative (MVEC) provides electric energy to a large
portion of Chanhassen and the surrounding areas, as designated by the Minnesota Public
Utilities Commission. The area has experienced rapid growth in recent years.
Completion ofthe St. Highway 312 project is anticipated to significantly drive more new
growth until land use saturates.
Technical analysis of the system targeted the need for a new electrical substation site
within the target area while accounting for the presence of existing distribution feeders
and transmission lines as well as existing and future load projections. .
The proposed site selected is a portion of unused property owned by M. A. Gedney and
zoned Industrial Office Park District (lOP). The site is located north of an existing Xcel
Energy switching station, east of the M. A. Gedney plant, west ofa St. John's Lutheran
Cemetery and south of additional industrial office park property owned by MA Gedney.
The specific legal description of the location under consideration is:
Beginning in the Northwestern Quarter of Section 3, Township 115N, Range 23W which
lies South 88 degrees 23 minutes 19 seconds East a distance of2313.94 feet from NW 3
monument located NW 3 in the Northwest Quarter of Section 3, Township 115N, Range
23W; Thence South 2 degrees 43 minutes 26 seconds West a distance of 193.29 feet.
Thence South 0 degrees 18 minutes 10 seconds West a distance of 418.76 feet
Thence South 57 degrees 57 minutes 21 seconds West a distance of 149.63 feet.
Thence South 0 degrees 38 minutes 38 seconds West a distance of171.50 feet.
Thence South 62 degrees 53 minutes 44 seconds West a distance of35.77 feet.
Thence North 1 degrees 5 minutes 52 seconds East a distance of 171.62 feet.
Thence North 35 degrees 27 minutes 12 seconds West a distance of306.61 feet.
Thence North 53 degrees 13 minutes 52 seconds East a distance of 427.59 feet to point
of termination. The property consist of approximately 116,600 sq ft or about 2'~ acres.
Currently, a large portion ofMVEC's service area within Chanhassen and Eden Prairie is
serviced by the Bluff Creek Substation or the Chaska Substation. Bluff Creek is a joint
facility with Xcel Energy and the City of Chaska Public Utilities with MVEC having a
secondary ownership position. Further expansion capabilities are extremely limited for
MVEC within the facility and technical limitations also come into play. The Chaska Sub
is a facility owned by Chaska Public Utilities, also offers limited space rented for
MVEC's use. The new proposed installation will provide considerably more system
growth potential, improve MVEC system reliability and also provide some backup
capabilities to both the Bluff Creek and Chaska Substations under emergency conditions.
11>
A major benefit of this site is that existing Xce1 Energy 115KV transmission line crosses
the property and eliminates the need to extend new transmission lines to the site. MVEC
is working jointly with Great River Energy (GRE) and Xce1 Energy to tap into this
location.
The presence of existing MVEC distribution feeder lines also contributes to economical
construction, maintenance, and lower costs to electric customers. Additional
underground distribution feeder lines will need to be installed to tie into other parts ofthe
system. The proposed location provides adequate system capacity for the foreseeable
future, and enhances system reliability for the area.
MVEC is pursuing a Conditional Use Permit (CUP) for a Public Utility Structure as an
essential service permitted by Article IV, Conditional Uses within standards set forth
within Division 4, Section 20.313 with some special consideration.. The facility proposed
would be a modem design, low profile Distribution substation with a modular switching
unit surrounded by a 10 foot pillar and walled concrete fence enclosure on three sides
replacing the standard 8 foot high chain link fence and barbed wire enclosure that is
typical for this type offacility. The enclosure measures 160 X 185. The remaining code
required fencing will be 8 feet high for safety and security, and access gates will be
locked at all times or under the direct supervision of authorized personnel. .
MVEC proposes additional conifers and shrubs strategically placed on the perimeter of
the property to break up and screen the site per the plan. All new vegetation will be
warranted for at least two years. Naturally existing trees and dense vegetation exist along
the east side of the property will remain to screen to the east side. Exit corridors for both
overhead and underground electrical feeders will be required to remain clear of tall
screening to assure system reliability. MVEC will install and maintain screening in the
form of shrubbery to the extent that they will not interfere with the reliability of the
substation operation. The substation will be maintained in a neat and orderly fashion.
Storm water drainage will be controlled on site to meet or exceed the City and watershed
requirements. The fenced in area will be maintained as a gravel surface. The driveway
and parking area will be blacktopped. Field inspection and available records indicate
significant wetlands will not be disturbed.
MVEC is providing the new substation site plan as part of the application. A purchase
option with M. A. Gedney, Inc. provides property interest to MVEC. MVEC is making
application to the Watershed District to review the specific conditions of the Conditional
Use Permit.
Signage will be limited to an identification sign on the fence of the substation, and
warning signs to the public as required by the current National Electrical Safety Code.
Within the fenced in area, a minimal quantity of transformers may be stored to
accommodate the prompt response to local outage situations.
I
7c.
Additional information:
The proposed substation will reduce the electric transmission line voltage from 115 KV
down to 12.47 KV for distribution to the local service area. A Local Distribution
Substation of this variety will contain transformation, regulation, metering and switching
capabilities. A modular, self contained control unit will be incorporated within the fenced
in area to monitor and regulate the functions of the facility.
Many functions are monitored remotely and access is most prevalent to respond to outage
conditions or to maintain the grounds. Most access is during daylight hours however 24/7
access is required. Site visits typically are only for duration of a few minutes. Once
constructed, trips generated per day will vary but typically would average only a few trips
per week. .
Vehicles accessing the facility typically are pickup type trucks or utility bucket truck type
vehicles and not normally more than two at a time. Short term parking will be provided
which will accommodate parking for up to 4 utility vehicles in front of the fence. Some
units may occasionally pull trailers.
No water or sewer will be utilized as part of the operations ofthe electrical substation.
The substation design will comply with the State Building and Fire Code. In addition,
the design will comply with the current National Electrical Safety Code.
MVEC's application includes provisions for variances and subdivision as noted.
This project enhances the electrical distribution system capabilities and reliability for the
customers in the immediate area. MVEC would intend to start construction as soon as
possible with the facility placed in service in late spring of2006.

Chanhassen Substation Standards
Sec. 20-313. Electrical distribution and undemround electric distribution
substations.
Electrical distribution and underground electric distribution substations are subject to the
following conditions:
(1) The distribution and underground electric distribution substations must be served
by a collector or major arterial street as designated in the comprehensive plan.
· The site is served by Stoughton Avenue. The current street provides access to the
Gedney plant as well as other industrial facilities within the general area.
(2) The distribution and underground electric distribution substations will not have
sanitary facilities and will not be used for habitation.
· MVEC' s on site operations short term require no habitation or extended presence
and has no need for sewer.
(3) The distribution and underground electric distribution substations will be located
on at least five acres of property.
· Actual area within the fenced premises is less than 3/4 acre. An over all area of
2.5 acres generously provides setbacks, parking and any landscaping. Highest and
best use of the property would not support the need for additional property for this
facility which would remain underutilized.
(4) A security fence as specified in the National Electric Safety Code shall surround
the distribution and underground electric distribution substations.
· Normally an 8 foot chain link fence with two strands of barbed wire would be
utilized for the entire enclosure. MVEC proposes alO foot modular concrete wall
type enclosure for the most visible areas as noted on the plans with the standard
chain link fencing for the remainder as noted on the plan.
(5) A landscaping plan shall be submitted for city approval.
· Due to the addition of walled screening, landscaping is confmed to the parking
areas, the remainder of the chain link portions and strategically located along
walled sections..
(6) Distribution and underground electric distribution substations shall be a minimum
of500 feet from single-family residences.
· The facility is positioned approximately 400 feet away from the closest mobile
homes however the existing Xcel switch station is located closer and across the
street from the same homes and existing transmission lines cross above those
homes. These homes would experience no increased impact from the proposed
substation facility.
(7) A summary of current research regarding the health effects of EMF levels,
conducted by health and scientific professionals, including those who do and do not
receive utility sponsorship.
· A study by The National Institute of Environmental Health Sciences, The
Environmental Protection Agency (EP A) and the US Department of Labor
Occupational Safety and Health Administration has been provided along with
references to various other web sites. In summary, EMF levels generated within
-Z6
the substation facility are projected to be reduced to near normal background
levels at the fence perimeter
(8) Provide EMF levels under maximum and average anticipated loading at the base of
the utility poles, underneath the wires between the poles, at ground level above
underground wires, at the edge ofthe property line, at the edge ofthe closest habitable
building, and at the point above ground where there would be the greatest EMF level.
. See diagram provided.
(9) Reasonable and prudent measures to minimize EMF levels along all alternative
electric line routes.
. Per EMF-Rapid study, the EMF levels within a substation drop off dramatically
as distance from equipment is increased. At the substation fence, EMF levels are
indistinguishable from background levels. MVEC has verified this to be true by
taking our own measurements. Distribution voltage lines, both overhead and
underground, have very low EMF levels and also are indistinguishable from
background levels at a short distance.
(10) Depictions of the views of the proposed facility, ifabove ground, from at least
two directions selected by city staff.
. Please reference plan views provided.
(11) The site is guided office/industrial on the City ofChanhassen Land Use Plan.
. The "Gedney" site is so designated per staff and the current zoning map.

You cannot see a magnetic field, but this illustration represents how
the strength of the magnetic field can diminish just 1-2 feet (30-61
centimeters) from the source. This magnetic field is a 60-Hz power-
freq uency field.

A Comparison of Electric and Magnetic Fields
Electric Fie Ids

· Measured in volts per meter (VIm)
or in kilovolts per' meter (kV/m). },
· Easily shielded (weakened) by

Magnetic Fields
· Produced by current.
Lamp plugged in and turned un. Current
nO\/lj rJwduces a rl'1agn~tic field aho.
· Measured in gauss (G) or testa (T).
. Not easily shielded (weakened) by
most material.
· Strength decreases rapidly I,Nith
increasing distance from the source.
An appliance that is plugged in and therefore connected to a source
of electricity has an electric field even when the appliance is turned
off. To produce a magnetic field, the appliance must be plugged in
and turned on so that the current is flowing.

1.0 Introduction
Great River Energy (GRE), located in Elk River, MN, provides generation and
transmission to 28 member cooperatives in Minnesota. GRE and one of its
cooperatives, Minnesota Valley Electric Cooperative (MVEC), are planning to construct
a new substation and high voltage transmission line tap in Chanhassen, Carver County,
Minnesota (Figure 1-1).
1 .1 Project Location
The new substation and tap will be located on a 2.9 - acre site east of Audubon Road
and north of Stoughton Avenue in an industrial area adjacent to the MA Gedney Plant in
Chanhassen, Section 3, T115N, R23W, Chaska Township, Carver County. The site
includes property previously owned by Xcel Energy. The new single circuit 115 kV
transmission line will tap an existing 115 kV transmission line (owned by and operated
by Xcel Energy) just northeast of the proposed substation site (Figure 1-2).
1.2 Project Description
The proposed project includes three primary components:
. MVEC plans to construct a new 115/12.5 kilovolt (kV) substation to be named the
Chanhassen Substation. The substation site will be owned by MVEC and all
distribution facilities will be constructed, operated and maintained by MVEC.
. GRE proposes to construct, own, and operate approximately 80 feet of 115 kV
transmission line to energize the new substation (Figure 1-2). The line will be a
single circuit design and will tap an existing 115 kV transmission line that is
owned and operated by Xcel Energy. GRE will also own transmission switching
facilities located in the substation.
. The Xcel Energy East Chaska Switching Station will be removed.
Each of these components is discussed in more detail below.
Substation
Electric facilities in the substation will include a 115/12.5 kV distribution transformer
(Figure 1-3).
Some equipment within the substation is filled with mineral oil for cooling. This
equipment will be sitting on concrete pads with three inches of crushed rock covering
the entire fenced-in area in the event of an equipment leak. Substation sites are
inspected on a monthly basis to check for leaks.

Plot PI"n.d~
The substation equipment will be enclosed in a 155' by 200' area situated inside the 2.9
- acre parcel. A decorative wall (stone patterned concrete wall made up of panels and
pillars) will be placed on three sides (north, west and south) and a chain link fence will
be placed on the east side. Additionally, the site will be surrounded with 58 trees and
shrubs, as well as various small plantings.
The wall and fence will be designed to deter animals and to provide safety and security.
Transmission Facilities
The transmission line serving the Chanhassen Substation will be a single circuit design.
A single span of wires will run down the transmission corridor and terminate on two
deadend, A-Frame structures. The line will then drop down through switches on to steel
buswork. The two A-Frame structures will be 65-75 feet tall, to match the height of the
existing transmission circuit in the vicinity. Each structure will carry three wires and a
separate shield wire for lightning protection.
There will be self-supporting, tapered, tubular steel poles and guyed wood structures to
route the transmission conductors in and around the substation.
Switchinq Station Removal
The older existing lattice Xcel Energy East Chaska switching station located
immediately adjacent to Stoughton Avenue will be removed as part of the project. The
old site will be converted to green space and provide driveway access to the new facility
located further north.
All transmission wiring will be reconfigured to route in and around the new Chanhassen
Substation.
1 .3 Project Need
This project is needed due to rapid growth in the MVEC service territory and associated
increases in electrical load growth. The project will improve MVEC system reliability
and provide some backup capabilities to the Bluff Creek and Chaska Tap substations
under emergency conditions. The new substation will also help eliminate the present
capacity limitations of these substations.
1.4 Project Cost Estimate
The estimated cost for the MVEC's distribution substation facilities is $1.6 million,
including site acquisition, site preparation, equipment, construction, and demolition of
the Xcel Energy switching station. The estimated costs for GRE's transmission and
substation facilities are $250,000 and $500,000, respectively. Total project cost is
estimated to be $2,350,000.

2.0 Regulatory Framework
2.1 Permit Requirement
This project falls under the State of Minnesota's Power Plant Siting Act, (Minnesota
Statutes 9 116C.51-.69 and Minnesota Rules Chapter 4400) for transmission projects
over 100 kV and requires a permit from the Minnesota Public Utilities Commission
(Commission). However, for eligible projects, a utility may apply to the local unit of
government that has jurisdiction over the project for approval instead of applying to the
Commission (Minn. Rules pt. 4400.5000). This proposed 115 kV substation project is
eligible for local review.
The City of Chanhassen has agreed to act as the lead local unit of government with
jurisdiction to approve the project. The City of Chanhassen was afforded the
opportunity to relinquish its jurisdiction by requesting that the Commission assume
jurisdiction, but has elected to maintain jurisdiction of the project. As required by Minn.
Rules pt. 4400.5000 Subp.3, a project notice was sent to those persons on the Power
Plant Siting General Notification list (see Appendix A).
2.2 Environmental Assessment Requirement
In accordance with Minn. Rules pt. 4400.5000 Subp.5, an environmental assessment
(EA) prepared by the local unit of government with jurisdiction over the project must be
completed. The EA contains information on the human and environmental impacts of
the proposed project and addresses methods to mitigate such impacts.
When the EA is complete, the City of Chanhassen must publish a notice in the
Environmental Quality Board (EQB) Monitor that the EA is available for review, how a
copy of the document may be reviewed, that the public may comment on the document,
and the procedure for submitting comments to the City. A final decision on the project
cannot be made until at least ten days after the notice appears in the EQB Monitor.
2.3 Scoping of Environmental Impacts
The rules require that the public be afforded the opportunity to participate in developing
the scope of the EA before it is prepared. The City of Chanhassen held a meeting on
November 15, 2005 to obtain input from the public on the scope of the EA. A notice of
the meeting was published in the Chanhassen Villager and a copy of the notice was
direct-mailed to interested parties and residents near the proposed project (see
Appendix A). One member of the public attended the meeting (a member of the
Cemetery Board) but did not offer comment on the project.
2-1
2.4 Conditional Use Permit
The City of Chanhassen requires a Conditional Use Permit for this project. MVEC
submitted a Conditional Use Permit Application to the City of Chanhassen on
September 2, 2005. The City of Chanhassen will hold a public hearing on January 3,
2006 regarding MVEC and GRE's request for a Conditional Use Permit. The City of
Chanhassen will make a decision on the application after notice of the EA has been
published in the EQB Monitor and the comment period requirements have been met.
2-2
3.0 Assessment of Impacts and Mitigation
This is a small project located in an industrial area and impacts to the environment are
expected to be minimal and short-term, therefore little mitigation will be required. MVEC
and GRE will minimize negative environmental impacts during construction of the
project.
Correspondence relative to environmental conditions at the proposed site and
responses received from state and federal agencies that reviewed the project are
provided in Appendix B.
3.1 Description of Environmental Setting
The proposed substation project is located in an area zoned Office Industrial. The
parcel purchased for the substation is currently undeveloped and land use in adjacent
parcels is as follows:
West side of the property - MA Gedney Plant
North side of the property - undeveloped
East side of the property - cemetery
South side of the property - Stoughton Avenue
3.2 Impacts on Human Settlement
3.2.1 Socioeconomics
The local economy is based primarily on office/industrial businesses, which employ over
8,000 people. Approximately 5-10 workers will be required for construction of the new
substation and tap line. During construction, there would be a small impact on the local
community due to revenue created from expenditures of the construction crew (local
community services, hotels, restaurants, construction materials). No permanent jobs
will be created by this project.
3.2.2 Displacement
The new substation and transmission line tap will not cause the displacement of any
residence and will not affect any public services. The substation will be set back
approximately 200 feet north of Stoughton Avenue. The only residences in the area are
south of Stoughton Avenue and are at a much lower elevation, and therefore will not be
affected by the project.
3.2.3 Noise
The proposed substation will be designed and constructed to comply with State of
Minnesota noise standards. It has been determined that there will be negligible noise at
3-1
the property boundaries. The substation transformer will be designed in accordance
with ANSI standards.
3.2.4 Aesthetics
The substation and transmission line as designed will have little impact on aesthetics of
the area. This is an industrial area with many transmission lines, therefore the new
substation will not significantly alter the existing character of the area. The site currently
consists of grasses and minimal tree cover, many of which are dead or dying. The
aesthetics will actually be improved along Stoughton Avenue when the existing Xcel
Energy East Chaska switching station is removed as part of this project.
The new substation facility will be set back from the road and will not be within the
viewshed of residences along Stoughton Avenue, as those residences are at a much
lower elevation south of the road. The substation equipment area will be enclosed with
a decorative wall on three sides (north, west and south) and a chain link fence on the
east side. Additionally, the site will be surrounded with 58 trees and shrubs, as well as
various small plantings.
3.2.5 Human Health and Safety
No threats to public health and safety are anticipated for this project. All facilities will be
constructed in accordance with all applicable standards, including standards of the
Rural Utilities Service (RUS), the National Electric Safety Code, and other industry
standards. Construction personnel will be required to follow Occupational Safety and
Health Administration regulations. Other safety measures such as warning signs,
fencing, and gates will be utilized as needed.
Electric and Maqnetic Fields
Questions often arise about electric and magnetic fields (EMF), which are invisible lines
of force that surround any electrical device. The term EMF refers to electric and
magnetic fields that are coupled together such as in high frequency radiating fields. For
lower frequencies such as for power lines, EMF should be separated into electric fields
and magnetic fields. Transmission lines operate at a frequency of 60 hertz (cycles per
second), which is in the non-ionizing portion of the electromagnetic frequency spectrum.
Fields are considered ionizing when they cause electrons to eject from their orbits
around a normal atom. This will typically occur with frequencies in the range of 1016 to
1022 hertz.
Magnetic fields result from the flow of electricity (current) in the transmission line. The
intensity of the magnetic field is related to the current flow through the conductors. The
magnetic field associated with the transmission line surrounds the conductor and rapidly
decreases with the distance from the conductor. The value of the magnetic field density
is expressed in the unit of gauss or milligauss.
3-2
The most recent and exhaustive studies of the health effects from power frequency
fields conclude that the evidence of health risk is weak. Some of these studies are
listed below:
. National Institute of Environmental Health Sciences. 2002. EMF. Electric and
Magnetic Fields Associated with the Use of Electric Power. National Institutes of
Health.
. National Research Council. 1997. Possible Health Effects of Exposure to
Residential Electric and Magnetic Fields.
. Minnesota Department of Health. 2002. EMF White Paper on Electric and
Magnetic Field (EMF) Policy and Mitigation Options.
. Electric and Magnetic Fields (EMF): Environmental Health in Minnesota.
http://www.health.state.mn.us/divs/eh/radiation/emf
For this project, the overall EMF impact will not change at the property lines. With the
retirement of the Xcel Energy East Chaska Switching Station, the overall EMF readings
on the property are anticipated to decrease closer to the road. In the area of the new
substation, the EMF will increase slightly, with new transformer and distribution facilities.
3.3 Impacts on Land-based Economies
3.3.1 Recreation
The proposed project is not near any recreational areas and will not affect recreational
opportunities.
3.3.2 Prime Farmland
The Natural Resources Conservation Service (NRCS) was contacted regarding soil
resources in the vicinity of the project. In a letter dated May 4, 2005, the NRCS
indicated that the proposed construction will not affect any prime farmland soils or land
of statewide importance.
3.3.3 Transportation
The site will have a paved entrance located in the area of the gravel entrance currently
serving the existing Xcel Energy switching station. This entrance will provide access
from Stoughton Avenue, an existing city street. No offsite roadway improvements will
be needed for equipment delivery. The proposed project is approximately six miles
from the nearest airport (Flying Cloud Airport). The United States Geological Survey
(USGS) elevation at the project site is 760 feet while the airport elevation is 900 feet, or
nearly 140 feet higher. The project will therefore not be a hazard to aviation.

.3.3.4 Mining and Forestry
There are no mining or forestry areas in the vicinity of the project.
3.3.5 Archaeological and Historic Resources
The Minnesota Historical Society State Historic Preservation Office (SHPO) was
contacted about the presence of archaeological, historical or architectural resources
located on or near the site. In a letter dated May 13, 2005, SHPO indicated that no
historic properties eligible for or listed on the National Register of Historic Places will be
affected by this project.
3.4 Natural Environment
3.4.1 Air Quality
Because electric substations and transmission lines do not affect air quality, there will
be no long-term environmental impacts on the air. Temporary air quality impacts would
be expected to occur during the construction phase of the project. However, adverse
impacts to the surrounding environment will be minimal because of the short and
intermittent nature of the emission and dust-producing construction phase.
3.4.2 Water Resources, Wetlands, Stormwater, and Soils
No impacts to water resources are anticipated. The substation site does not contain
any existing wetlands or have any impact on groundwater or other surface waters.
The US Army Corps of Engineers (USACE) was contacted regarding this project and in
an e-mail response dated August 25, 2005, the USACE indicated no permit or other
approvals were required.
There are no Minnesota Department of Natural Resources (DNR) Public Waters in the
vicinity of the project (Figure 3-1).
The stormwater runoff drainage patterns from the proposed site will mimic the existing
conditions of the land. The majority of the site will drain to an infiltration area, which will
retain the volume of runoff produced from a 6" rainfall event. The site overflows to the
southwest and ultimately to the Minnesota River.
The proposed site will require some grading. Minimal erosion may occur at the site
during construction, but erosion and sediment will be controlled on-site with all

appropriate best management practices (BMPs) in place for the duration of the
construction activity. The site meets the design standards of local, state, and federal
agencies and an NPDES permit application will be submitted to the Minnesota Pollution
Control Agency prior to construction initiation.
A Phase II Environmental Site Assessment conducted by Braun Intertec reported no
conditions at the site that would require special environmental regulatory actions.
3.4.3 Vegetation and Wildlife/Rare and Unique Natural Resources
The DNR and the United States Department of the Interior Fish and Wildlife Service
(USFWS) were contacted regarding vegetation and wildlife resources in the vicinity of
the project.
In a letter of April 25, 2005, the DNR indicated that there are a number of rare species
or natural communities in the general project area. However, based on the nature and
location of the proposed project, it will not affect any known occurrences of rare features
(Figure 3-2).
The USFWS (e-mail of April 13, 2005) indicated that the bald eagle is documented to
nest in Carver County. However, given the location (not within areas with known
nesting bald eagles) and type of activity proposed, it is not likely to adversely affect any
federally listed species.
Effects on area wildlife will be minimal. The substation is designed to deter animal
entry.

5.0 Potential Future Areawide Infrastructure
The study area, described below, lies within both the City of Chaska and the City of
Chanhassen. As shown in Figure 5-1, Areas 1 and 2 are in Chanhassen and Areas 3
and 4 are in Chaska. The proposed substation site lies within the easternmost part of
Area 2 with the proposed access drive through the southwesterly corner of Area 4.
Based on both cities' Land Use Guide Plans and Zoning Maps, the entire area was
analyzed to determine the feasibility of future development in this area and how public
services could be provided to enable future development to take place. An analysis of
the traffic impacts and public utilities that would be needed for a feasible future
development scenario using all of the potentially developable land in this area is included
below.
5.1 Street Layout and Traffic Analysis
The area is bordered by US Highway 212 on the north and east, by Stoughton Avenue
on the south, and by Audubon Road on the west. A strip of land that is abandoned
railroad right-of-way bisects the area. The Hennepin County Regional Railroad Authority
owns the eastern end of this strip of land and it is currently not developed with a trail. A
regional recreational trail east of US Highway 212 is constructed and operated by Three
Rivers Park District. The Chaska Economic Development Authority and MA Gedney
Company own the balance of the abandoned right-of-way.
Table 5-1 identifies the current zoning classifications and general land use development
assumptions for developing trip generation and general distribution assumptions. Figure
5-1 illustrates Areas 1-4 described in the table.

he entire District does not exceed. 75. Lot coveraqe bv buildinqs shall be no more than 40% of the lot.
Table 5-2 shows 6,754 trips will be generated by the assumed land uses. Based on
existing travel patterns it has been assumed that 19.2% of the trips will go to or from
Audubon Road, 16.5% to/from Engler Boulevard, 31.4% to/from the west on Highway 212,
29.6% to/from the east on Highway 212, and 3.3% to/from the west on Stoughton Avenue.

Based on the 2003 annual average daily traffic (ADT) volumes and land use assumptions
outlined above, traffic volumes were developed for two different internal street layout
alternatives. The internal street layout options and corresponding ADT are illustrated in
Figures 5-2 and 5-3.
5-3
With either of these street layouts, along with the existing road network, the additional
traffic demand could be accommodated and it is anticipated that vehicle-related air
emissions would remain at acceptable MPCA levels.
5.2 Sanitary Sewer and Watermain Service
The majority of the area studied does not currently have utility services nearby. The
exception is the Gedney factory in the southwestern-most portion of Chanhassen, which
has sanitary sewer and water service provided by the City of Chaska.
The City of Chanhassen's comprehensive plan indicates that a gravity sewer extending
from a future lift station located between Bluff Creek Drive and Highway 101
(approximately 5,500 feet to the northeast) would service the sanitary needs of the
Chanhassen portion of the study area. This sewer and the extended sewer needed to
serve the remainder of the study area are shown in Figure 5-4. The 59.6 acres of future
office/industrial land use, not including the cemetery area, yield a projected daily peak flow
rate of 125 gallons per minute. This indicates that an 8" gravity sanitary line at minimum
grade can adequately service the Chanhassen portion of the study area, as well as the
land in Chaska, if desired.

The Chanhassen portion of the study area is within the "Lower Bluff Pressure Zone" as
identified in the water distribution figure of the City of Chanhassen's comprehensive plan.
This figure shows a future 12" watermain extending west from Bluff Creek Drive, which
has been reproduced in Figure 5-4. This main, or perhaps a smaller size pipe (depending
on the fireflow requirements of the City), could be extended further west to serve the
remainder of the study area, including the Gedney property. This scenario would provide
an undesirable "dead end" in the water system unless the piping was looped back to the
main, which may prove too costly to be feasible. Another, and perhaps more economical,
option is for the City of Chanhassen to enter into an agreement with the City of Chaska to
provide water service to the area in question.
The portion of the study area within the City of Chaska was considered for water service
during the recent development process of adjacent land to the west. That development,
Chaska Gateway, installed a 12" watermain, which would provide adequate flows to the
current study area.
5.3 Stormwater Management
The study area is within the Lower Minnesota River Watershed District (LMRWD), which
requires that runoff discharge rates after development are equal to or less than the
existing flow rates leaving the site. The LMRWD does not have its own permitting
process, but instead relies on the local governmental units to monitor the development
activity for compliance.
It is assumed that the future development of the study area will manage and treat
stormwater runoff through the construction of retention or wet sedimentation basins to the
design standards of the nationwide urban runoff program (NURP). For the purposes of
this study, a regional approach to stormwater management has been assumed. That is,
an attempt has been made to minimize the amount of ponding through consolidation and
strategic placement of the basins. These basins would provide permanent treatment of
the runoff and would be maintained as per the City's comprehensive stormwater
management plan.
As shown in Figure 5-5, three potential ponding locations have been identified from the
ten-foot contours of the USGS quadrangle maps. Pond 1 is proposed to treat runoff from
the western portion of the Chanhassen area prior to discharging to the west. Ponds 2 and
3 would discharge to the east after treating water from the eastern Chanhassen property
and Chaska property, respectively. These basins have been roughly sized for potential
future land uses to provide the NURP-recommended dead-pool storage volumes as
shown in Table 5-3.

2 Normal Water Level Area
The study area contains approximately 67.9 acres of Hydrologic Soil Group Type A soils,
primarily consisting of Hubbard and Alluvial soils. These soils are very well drained and
provide for some of the highest infiltration rates in Carver County. Because of this, it is
recommended that future development planning consider infiltration techniques in addition
to, or in lieu of, the wet sedimentation basins described above. These measures could
include: infiltration swales and basins, rock trenches, as well as vegetated swales and rain
gardens. The design of these techniques is dependent upon an in-depth site analysis and
would occur as part of a detailed development process. The 2.5-acre site being
considered for the MVEC substation will control runoff rates and minimize runoff volume
through the construction of an infiltration basin. This basin will infiltrate 15,700 cubic feet
of runoff prior to overflowing to the southwest.
All construction activity will utilize the appropriate BMPs to minimize erosion and sediment
transport during construction. If more than one acre of land is disturbed, a SWPPP will be
developed and the associated NPDES permit obtained.
5-8
6.0 Anticipated Staging of Various Developments .
MVEC is anticipating the construction of the new Chanhassen Substation along with
GRE's high voltage transmission line tap in time to meet the peak power demand of early
summer 2006. The other possible development scenarios analyzed in Section 5.0 will not
likely occur until well into the future. The Business Fringe zoning district designation for
Area 1 is intended to accommodate limited commercial uses temporary in nature without
urban services, while maintaining the integrity, minimizing impact, and protecting the
natural environment. Because there is no schedule for providing urban services to this
area from those existing in Chanhassen, any potential development would need to provide
their own private on-site systems. This would likely be cost prohibitive, at least into the
foreseeable future. Area 2, which includes the existing Gedney factory, would be very
expensive to redevelop and this also is not likely in the foreseeable future. There may be
a possibility for new development of the northerly 6.2 acres of the separate parcel of
Gedney-owned property; however the City of Chaska may not have sewer capacity for any
additional development that is not within their city.
Area 3 is in the City of Chaska and water service would be available from the Chaska
Gateway development on the north side of US Highway 212; however sewer service
availability is questionable. This area could be sewered through the City of Chanhassen
as indicated in Section 5.2, but this would not likely occur for many years. If sewer
capacity is available through Chaska's existing system, there would be considerable
expense involved with the necessary extension under US Highway 212 and possibly the
need for a lift station. Therefore, future development of Area 3 does not appear to be a
very near term possibility.
Area 4 is an existing cemetery in the City of Chaska, except for the small parcel in the
southwest corner that is owned by Xcel Energy. No change in use is expected, although
access to the proposed substation site would be through the Xcel Energy parcel.
Any future development that would occur would involve modification of the ground
topography to accommodate new roads, drives, buildings, utilities and stormwater
management facilities. Due to the relatively flat terrain, no significant amount of earth
moving is anticipated.

RE: Chanhasscn Substation and liS kV Transmission line Project
Dear Sirs:
This letter confinns that the Public Utilities Commission (PUC)I has received notification that
Grcat River Energy (GRE) and Minnesota Valley Electric Cooperative (MVEC) propose to seek
local review to build a new 115 kV Substation and a one-span section of 115 kV HVTL tapping
into an existing GRE 115 kV line. The project would be constructed in the City ofOlanhasscn
in Carver County.
This project falls under the Power Plant Siting Act, Minnesota Statutes * 116C.51-69 and
Minnesota Rules Chapter 4400, which requires a penn it from the PUC for most transmission line
projects over 100 kV. However, for eligible projects. a utility may apply to those local units of
government that have jurisdiction over the route for approval to build the project instead of
applying to the PUC. The proposed 115 kV substation and transmission project is eligible for
local review. [Minnesota Statutes 9 116C.576 and Minnesota Rules 4400.5000 subps. 2. C., D.]
GRE and MVEC have indicated that the City ofChanhassen is the only local unit of government
with jurisdiction in permitting the proje~t and that a Omditional Use Pennit application wa<;
submitted to the City on September 2. 2005. A local unit of government may relinquish its
jurisdiction by requesting the pue to assume jurisdiction within 60 days of the filing of an
application with the local unit of government. [Minnesota Rules 4400.5000 subp. 4.)
I On July 1,2005, Minnesota Senate File t368 transferred generation plant siting and lransmissiollline routing
authority from the Minnesota Em'ironmental Quality Board to the Public Utilities Commission. EQB routing and
siting staff was transferred to the Department of Commerce and continue to m31U1gc the application process.

Specific requirements with regard to the environmental review process include providing an
opportunity for the public to participate in the development of the scope oftlle environmental
assessment before it is prepared; publishing notice in the EQB Monitor of when the assessment
is available for review and ufthe procedure for commenting on the assessment; and withholding
a final decision on the project until at least ten days after the notice appears in the EQll Monitor.
The City of Chanhassen also must provide a copy of the environmental assessment to the PUC
when it is completed. [Minnesota Rules 4400.5000 subp. 5.]
GRE and MVEC have sent the required notice to those persons on the PUC facilities permitting
general notification list that a permit has been applied for from the local unit of government.
[Milmesota Rules 4400.5000 subp. 3.]
If there are any other questions, please feel free to contact me by phone or email.
