Known as Keystone XL, the 1,700-mile pipeline has drawn fierce criticism from environmentalists, who are staging a two-week demonstration at the White House. So far, some 370 people have been arrested for protesting the project.
"There would be no significant impacts to most resources along the proposed pipeline corridor," Bureau of Oceans and International Environmental and Scientific Affairs (OES) Assistant Secretary Kerri-Ann Jones told reporters on the release of the State Department's final environmental impact statement.
She stressed that the report is not the last word on the pipeline, which now must pass through a 90-day review period that will include public hearings. A final decision is expected before year-end.
Supporters say the pipeline would create jobs and let the United States replace Venezuelan or Middle Eastern imports with well-regulated, dependable Canadian crude.
Opponents say the project would bind the country to an unnecessary and dirty form of oil for decades to come and expose surrounding areas to dangerous spills and leaks.
