U.S. Sen. Joe Donnelly, D-Granger, has joined fellow Sens. Rob Portman, R-Ohio, and Claire McCaskill, D-Ohio, in introducing legislation aimed at improving the permitting process for large infrastructure projects.

The Federal Permitting Improvement Act would improve coordination among agencies and deadline-setting for permitting decisions, enhancing transparency and reducing litigation delays, according to a news release.

It would apply to construction projects totaling more than $25 million that require review by a federal agency, the release states.

One such project, the controversial Keystone XL oil pipeline, has been

delayed for more than a year now because of environmental concerns and other bureaucratic entanglements.

"My No. 1 priority is to help create jobs, and I think one of the best ways to create jobs is to establish the right conditions for the private sector to invest in our country's infrastructure," Donnelly said in a statement.

"This bipartisan legislation would encourage investment by requiring government agencies to work together to cut red tape, set deadlines and increase transparency.

"We should be building things in this country, and that means expediting the transportation, energy and other infrastructure projects that strengthen our economy."

The bill has been referred to the Senate Committee on Homeland Security and Government Affairs for further review.
