Keystone XL opponents allowed to participate in proceedings

(AP) – A commission that will decide whether to approve the Keystone XL in Nebraska is allowing the pipeline’s opponents to formally participate in its proceedings. The Nebraska Public Service Commission’s chairman says he will let groups such as the Bold Alliance, the Sierra Club and the Ponca Tribe of Nebraska become intervenors in the case. Intervenors are allowed to write legal briefs, cross-examine witnesses and present formal arguments alongside pipeline developer TransCanada’s attorneys.
