SALT LAKE CITY (AP) – Utah is seeking federal approval for plans to curb chronic air pollution along an urban corridor of 2 million residents.

State regulators put final touches on the plans Wednesday by adopting deadlines for new industrial emissions controls along the Wasatch Front.

The plans are taking effect in state law even as regulators submit them to the U.S. Environmental Protection Agency for approval.

The EPA says it’s working closely with Utah and expects to improve the plans. That review could take months.

Clean-air advocates say Utah gave industry too much time to install new pollution controls. They’re hoping the EPA speeds up some deadlines.

The plans aren’t designed to achieve federal air quality standards until 2019 at the earliest. By then, Utah may have to find ways to cut emissions further as the federal government tightens air-quality standards.
