ENVIRONMENTAL IMPACT STATEMENTSCOPING DECISION DOCUMENT

PUC Docket No. E002/TL-09-1448

The above matter has come before the Director of the Office of Energy Security (OES) for a decision on the Scope of the Environmental Impact Statement (EIS) to be prepared on the Northern States Power Company route permit application before the Minnesota Public Utilities Commission (Commission) for the proposed transmission lines between Hampton, Minnesota and La Crosse, Wisconsin, under the full permitting process (Minnesota Rules 7850.1700 to7850.2700). Northern States Power Company (Xcel or Applicant) has submitted the route permit application on behalf of itself and other regional utilities participating in the CapX2020 initiative (Dairyland Power Cooperative, Southern Minnesota Municipal Power Agency, Rochester Public Utilities and WPPI Energy.)

PROJECT DESCRIPTION

The Applicant proposes to construct and operate a 345-kilovolt (kV) High Voltage Transmission Line (HVTL) between Hampton, Minnesota, and La Crosse, Wisconsin, and a 161 kV HVTL between a proposed substation to be located between Zumbrota and Pine Island, Minnesota, and an existing substation near Rochester, Minn. The Minnesota portion of the project involves up to 91 miles of 345 kV High Voltage Transmission Line (HVTL) and 15 miles of 161 kV HVTL located in Dakota, Goodhue, Olmsted, and Wabasha counties, Minnesota (Figure 1.) The proposed project would cross the Mississippi River into the State of Wisconsin at a location near Kellogg, Minnesota, and Alma, Wisconsin. The Project also includes construction of a new North Rochester substation, to be located between Zumbrota and Pine Island, Minnesota, and improvements to the existing Northern Hills substation, near Rochester. The proposed structures for the 345 kV HVTL are double circuit-capable, single-pole, self-weathering steel structures. The height of these poles will range from 130 to 170 feet, with the spans between poles ranging from 700 to 1,000 feet. The typical right-of-way width for the 345 kV transmission line is 150 feet. The proposed structures for the 161 kV HVTL are single-pole, steel structures 70 to 105 feet in height, with spans between the poles ranging from 400 to 700 feet. The typical right-of-way width for the 161 kV line is 80 feet. The Applicant has requested a route width of 1000 feet (the lateral area within which a transmission line right-of-way could be permitted) for both the 345 kV and 161 kV lines, and has identified a proposed centerline for right-of-way placement In some locations, the applicant has requested route widths greater than 1,000 feet near existing or anticipated future developments. The 345kV HVTL will be designed to have a minimum ground clearance of 34 feet. The 161 kV HVTL will have a minimum ground clearance of 26 feet.

Hampton-Rochester-La Crosse 345 kV and 161 kV Transmission Line Project Environmental Impact Statement Scoping Decision PUC Docket No. E002/TL-09-1448 Page 3 The estimated cost of the Project for facilities to be located in Minnesota is between $229 and $253 million (2009 dollars), depending on the final route selected. Construction of the Project is expected to begin in the third quarter of 2011. The applicant anticipates the 345 kV HVTL will be completed and the line in-service by second quarter 2015, and the 161 kV HVTL in-service by fourth quarter 2012.

PROJECT PURPOSE

As indicated by the Applicant in the route permit application, the project is designed to ensure continued reliable electric service to customers in the local Project area, to improve the reliability of the bulk electric system serving Minnesota and portions of neighboring states, and to facilitate generation development in southeastern Minnesota to meet each utility’s Renewable Energy Standards. Detailed information regarding the purpose and need for this transmission project is provided in the May 22, 2009, Order issued by the Commission granting Certificates of Need for the CapX 345 kV Transmission Projects, Docket No. ET-2, E-002, et al./CN-06-1115 (https://www.edockets.state.mn.us/EFiling/edockets/searchDocuments.do?method=showPoup&documentId={54C51FAE-B774-4EED-A93C-CAF6ECC5EB52}&documentTitle=20095-37752-01)

REGULATORY BACKGROUND

The Applicants filed a route permit application on January 19, 2010, under the full permitting process of the Power Plant Siting Act (Minnesota Statute 216E). The application was accepted as complete by the Commission on March 9, 2010. Under the full permitting process, the Commission has one year from the date the application was accepted as complete to make a decision on the route permit.

SCOPING PROCESS

Route permit applications for high voltage transmission lines are subject to environmental review in accordance with Minnesota Rules 7850.1700 to 7850.2700. Scoping is the first step in the permitting process after application acceptance. The scoping process has two primary purposes: to ensure that the public has a chance to participate in determining what routes and issues to study in the EIS, and to help focus the EIS on the most important issues surrounding the route permit decision. OES Energy Facility Permitting (EFP) staff collected and reviewed comments on the scope of the EIS by holding six Scoping Meetings and convening two advisory task forces. The EFP also accepted written comments from April 19, 2010, through May 20, 2010. This scope identifies potential human/environmental issues and project route and substation alternatives that will be addressed in the EIS. The scope also presents a tentative schedule of the environmental review process.

Hampton-Rochester-La Crosse 345 kV and 161 kV Transmission Line Project Environmental Impact Statement Scoping Decision PUC Docket No. E002/TL-09-1448 Page 4 Advisory Task Forces

In an Order dated March 16, 2010, the Commission authorized the establishment of two geographically-based advisory task forces that would each focus on approximately half the project area: the Hampton to Northern Hills Advisory Task Force (ATF) and the North Rochester to Mississippi River ATF. The ATFs were each charged with: (1) identifying local site or route specific impacts and issues of local concern, and (2) identifying alternative transmission line routes or substation locations in their respective area of concern that may maximize positive impacts and minimize or avoid negative impacts of the project. The task forces each met three times between April and June 2010. The recommendations of the ATFs have been considered during the preparation of this scope and can be found in their respective reports, dated June 30, 2010. The ATF reports are available on the EFP website at http://energyfacilities.puc.state.mn.us/Docket.html?Id=25731.

Public Scoping Meetings

Six public information and scoping meetings were conducted by the EFP May 4 through May 6, 2010, at three different locations along the proposed project routes: Plainview, Pine Island and Cannon Falls, Minn. Approximately 350 people attended the six public meetings. The scoping meetings provided the public an opportunity to learn about the proposed project and the route permitting process, review the route permit application, and ask questions and submit comments. A court reporter was present at each of the public meetings and transcribed questions asked and comments made by the public as well as responses from the EFP and the Applicant.

Public Comments

A public comment period beginning April 19, 2010, and ending on May 20, 2010, provided the public an additional opportunity to submit comments and alternative routes to be considered for the scope of the EIS. A total of 211 commenters provided comments by the close of the comment period, which includes written comments received via mail, email or facsimile and verbal comments submitted at the public scoping meetings.

The EIS will identify and evaluate alternative routes and route segments to the proposed project. Forty-six of the 54 alternative routes suggested through public comment, including routes developed by the ATFs, will be evaluated in the EIS and are presented below and illustrated in Figures 2 through 11. Just as the applicant has provided a proposed alignment and 1000-foot route width in their permit application, these route alternatives are depicted on the maps as the proposed alignment, and would carry a 1000-foot route width. The first number in the name of each route identifies which geographic region the alternative was proposed in [(1) 345 kV line from Hampton to the North Rochester Substation, (2) 161 kV from North Rochester Substation, and the (3) 345 kV line from the North Rochester Substation to the Minnesota terminus of the project.] The subsequent letter in the name refers to whether the route is an alternative to the applicant’s preferred (P), alternative (A), or both (B) routes. Some alternatives combine the 345 kV and 161 kV routes. These are identified with a letter “C.”

Route Alternatives on Figure 2

1A-001 – From the applicant's 345 kV alternate route in southwest Holden township in Goodhue County, Go South on 50th Ave for 0.5 mile, turn east and go cross-country 1 mile, then meet up with existing transmission line and continue east on MNTH 60 for 3 miles, where transmission line turns north.

ISSUES OUTSIDE THE SCOPE OF THE EIS

The following issues will not be considered or evaluated in the EIS: 1. Any route or substation alternatives not specifically identified in this scoping decision 2. Questions of need, including size, type, and timing; questions of alternative system

configurations; or questions of voltage.

3. The no-build option regarding the high voltage transmission line.

4. The impacts of specific energy sources, such as carbon outputs from coal-generated facilities.

5. The manner in which land owners are paid for transmission rights-of-way easements,

as that is outside the jurisdiction of Public Utilities Commission.

6. The following alternative routes suggested through public comment will not be considered for further study or evaluation in the EIS. The route segments were rejected as they either did not meet the stated need of the project as defined in the Certificate of Need (CapX 345 kV Transmission Projects, Docket No. ET-2, E-002, et al./CN-06-1115), had more impacts relative to the criteria used by the Commission in route permit determinations as defined in Minnesota Statue 216E.03, subd. 7., or were incomplete in their description and/or depiction.

A route alternative was suggested that would place the 345 kV transmission line along Highway 52 from Hampton, Minn. through Rochester to Interstate 90, where it would head east and cross the Mississippi River at La Crescent, Minn. This alternative would add significant length to the project, has significant constructability issues through the City of Rochester, and would impact more resources. The record provides information on the significant obstacles of approaching and crossing the Mississippi River at this location. A route alternative was suggested from the applicant's 345 kV preferred route in Watopa Township in Wabasha County, go east cross-country 0.2 miles. Turn northeast and go cross-country 2.2 miles. Turn north and go 0.15 miles cross-country returning to the applicant's 345 kV preferred route. This route would create a new transmission line corridor where none currently exists. This route is longer and impacts more resources.


A route alternative was suggested from the applicant's 345 kV alternate route, 0.1 miles south of the intersection of Mn 42 and CSAH 14 in Highland township in Wabasha County. Go north along CSAH 14 for 0.75 miles. Turn east on road T-530 and go for 0.4 miles. Merge with CSAH 14 again, and follow CSAH 14 east for 2 miles returning to the applicant's proposed 345 kV line. This route alternative is longer than the route is attempting to replace, affects more residences, and has more resource impacts. A route alternative was suggested from the applicant's 345 kV alternate route in southern Wanamingo township in Goodhue County, follow existing transmission line along MNTH 60 going east for .65 miles, then curve northeast with MNTH 60 and follow for .65 miles, then curve east and follow MNTH 60 for 3.5 miles. Turn south from the highway and the existing line and go cross-country 0.5 miles returning to the applicant's 345 kV alternate route. This route alternative would bi-sect the municipal boundary of the City of Wanamingo, and would affect more residences than other alternative routes in the area. A route alternative was suggested in Wabasha County that would follow, from the applicant’s preferred or alternate 345 kV route, County Roads 14 and 18, and joining the applicant’s Route Option south of the City of Kellogg. This route is substantially longer than other viable alternatives in the area, has constructability issues, and affects more resources. A route alternative was suggested from the applicant's 345 kV preferred route, 0.15 miles west of the intersection of US 52 and CSAH 7. Go east cross-country for 2.2 miles. Then turn south on CSAH 6 and go south for 1.3 miles. Turn east and go cross-country for 0.3 miles, then continue going east along 443rd sty for 0.35 miles. Then turn south and go cross-country for 2.25 miles. Turn SSW, crossing US 52, and go SSW cross-country for 0.6 miles. Then turn south and go cross-country for 1.2 miles past the proposed north substation location to a new proposed substation location further south. A route exiting this substation was also suggested from the applicant's 345 kV alternate route, 0.5 miles west of the intersection of US 52 and US 60. Go east cross-country for 0.5 miles to meet up with US 52. Follow US 52 south for 2.3 miles connecting to the applicant's 345 kV preferred route. This route is longer than the route it is attempting to replace, affects more residences, and provides constructability issues along an existing 345 kV transmission line. A route was suggested by commenters where the 345 kV transmission line would follow Highway 52 through the cities of Zumbrota and Oronoco, before turning east toward the Minnesota terminus of the project. This route would affect significantly more residences than the route segments it is attempting to replace. This alternative has more impacts relative to the criteria considered by the Commission in route permit decisions than the route segment it is attempting to replace.


A route alternative was suggested from the applicant's 345 kV route, in Watopa Township in Wabasha County on US 61 where the route and existing line cross US 61. Go southeast along US 61 for 0.25 miles. Turn northeast and go cross-country for 2.55 miles. Turn north and go cross-country for 0.25 miles to meet up with the applicant's 345 kV route at County Road 84. This route alternative would create a new corridor where one does not currently exist in a State Wildlife Management Area. This alternative has more impacts relative to the criteria considered by the Commission in route permit decisions than the route segment it is attempting to replace.
