TransCanada spokesman Shawn Howard says the Canadian pipeline company has identified a rough corridor, but not a specific route, through which the pipeline could run.

Howard says the proposal will be revealed during public hearings set by the Department of Environmental Quality, if a state review is allowed to proceed. Lawmakers have given first-round approval to a bill that would let the state restart its review, after President Barack Obama denied a federal permit in the face of a congressional deadline, halting the process.

Pipeline opponents say TransCanada is trying to secure landowner support before the corridor is unveiled.
