May 2009 Wisconsin Department of Natural Resources Enbridge Alberta Clipper Petroleum Pipeline and Related Projects Environmental Assessment 1 Environmental Assessment for Enbridge Alberta Clipper Petroleum Pipeline and Related Projects To the Reader This environmental assessment (EA) fulfills part of the Wisconsin Department of Natural Resources (DNR) requirements under the Wisconsin Environmental Policy Act (WEPA), Wis. Stat. § 1.11, and Chapter NR150, Wis. Adm. Code. WEPA requires state agencies to consider environmental factors when making major decisions. The purpose of this EA is to provide the decision makers, the public, and other stakeholders with an analysis of the economic, social, cultural, and environmental impacts that could result from the construction and operation of the proposed Enbridge Alberta Clipper petroleum pipeline, Southern Lights diluent pipeline, Superior Terminal pumping station, and Superior Terminal breakout tanks. The Department conducted an issue identification process prior to completion of the EA. The Department requested public scoping comments on March 11, 2009 and received public comments through March 31, 2009. The Department used those comments to help identify the scope and the significant issues that were analyzed in the analysis. Comments received during the comment period will be used by the Department to make its final decisions on this project. You are encouraged to comment on this EA. The EA is available on the Department web-site at: http://dnr.wi.gov/org/es/science/eis/eis.htm. The DNR has scheduled a public informational hearing where individuals can learn more about the proposed project and submit written or oral comments about the EA and any DNR wetland and waterway determinations associated with the project. The public informational hearing will be held on June 4, 2009 at the City of Superior Public Library, Large Meeting Room, 5:30 pm to 8:00 pm. The comment period on this EA ends on June 8, 2009. Written comments should be addressed to: Benjamin Callan Water Management Specialist WDNR (OE/7) PO Box 7921, 101 S. Webster Street Madison, WI 53707-7921 or via E-mail to: [email protected] All comments received during the hearing and written comments received before the end of the comment period will be considered by the Department before issuance of a record of decision under s. NR 150.24, Wis. Adm. Code. The DNR also cooperated with the U.S. Department of State (USDOS) on a federal Environmental Impact Statement (EIS) for the Alberta Clipper petroleum pipeline project.
