State Department officials said June 6 that the agency has received thousands of public comments on a supplemental environmental impact statement for the proposed $7 billion, 1,700 mile Keystone XL tar sands pipeline. The agency plans to make a decision on whether to grand a cross-border permit by the end of the year, and June 6 was the deadline for filing comments on the statement, but the agency will hold six additional forums for public comment as it reviews permit applications for the pipeline. The current statement found no major environmental issues that could not be mitigated, but he Environmental Protection Agency has objected to the statement because it contains insufficient information to fully assess the project’s effects on groundwater, alternative pipeline routes, greenhouse gas emissions, wetlands, and migratory birds.
