Keystone XL review lacking?

The U.S. Environmental Protection Agency criticized the State Department’s environmental review of the proposed Keystone XL pipeline in a letter to the agency’s administration.

The EPA’s letter said there was not enough evidence to support the State Department’s conclusions on gas emissions, safety and alternative routes for the pipeline, according to the Los Angeles Times. The criticism comes during the public comment period for the draft report assessing the possible effects of the pipeline on air, water, endangered species, communities and the economy.

President Obama will make a final decision on the feasibility of the Keystone XL this summer. If approved, the pipeline would transport tar-sands oil from Alberta, Canada, to refineries along the Texas Gulf Coast.
