Draft Environmental Impact Statement issued on Rackdale-West Middleton

MADISON – The Public Service Commission of Wisconsin (PSC) has prepared a draft Environmental Impact Statement (EIS) for a proposed 345 Kilovolt (kV) transmission line from Rockdale to West Middleton and is seeking public input.

In 2007, American Transmission Company (ATC) filed an application with the PSC for permission to build between 32 and 55 miles of new 345 kilovolt transmission line from the west side of Middleton to the eastern side of Dane County. The application also includes proposed substations and related facilities along four different route options, including routes along the Beltline in the City of Madison.

The draft EIS is a thorough study of the proposed project, outlining the potential for environmental, community and public health impacts. All public comments on the draft EIS will be considered when drafting the final EIS. Members of the public are encouraged to use the final EIS to help prepare for public hearings to be held next year.

The PSC has the authority to approve, deny or modify any proposed electric construction project. To ensure a full and complete record, the PSC follows a process outlined by state law for every case. Part of this process is to perform a thorough environmental review and to gather input from the public.

The PSC is looking for the public and energy stakeholders to comment on the draft report by December 29, 2008.

Copies of the draft EIS are available upon request by calling (800) 358-9246 or contact Christine Swailes by email at It is available in either electronic (CD), *.PDF format or paper.

To review the report, it may be accessed at the PSC’s website at To view the documents, click on the Electronic Regulatory Filing System (ERF) and enter docket number 137-CE-147.
