A bipartisan group of 34 senators is putting fresh political pressure on Energy Secretary Ernest Moniz to approve industry natural gas export applications that have piled up at the Energy Department.

The lawmakers, led by Sens. James Inhofe (R-Okla.) and Mark Begich (D-Alaska), are also seeking certain changes to the review process aimed at speeding up approvals.

Moniz said in mid-June that he’s moving into a case-by-case review of applications, which follows a wider examination of data underpinning the Department of Energy’s analyses of the industry plans.

A new Senate letter to Moniz expresses concern that DOE’s timeline for decision-making will be too slow, leading the United States to lose out on global market share.
