Iowa fire marshal: 5 stores statewide selling fireworks

Other fireworks businesses are completing applications, including chains such as Wal-Mart, Sam's Club, Target, Big Lots and Bomgaars.

The reviews of permanent structure site plans are taking more time than anticipated, and the office is looking to speed up the process without jeopardizing safety, the Department of Public Safety noted the statement.

Retail firework licensing fees, designed to offset some of the start-up costs for the state, will probably not be available for use until the next fiscal year, which begins July 1.
