On May 5, 2014, EPA observed fugitive particulate emissions originating from Lindahl's California Avenue Facility traveling beyond its property line and crossing the I-55 highway, in violation of the Illinois SIP. On July 23, 2014, representatives of Lindahl and EPA discussed the alleged violations at the Facility. On July 28, 2014, the Facility installed an additional water nozzle at the transfer point that caused the fugitive emission to cross the property boundary reducing fugitive emissions by 500 pounds per year. This ACO will require Lindahl to incorporate a dust fugitive plan into its air operating permit and continuously operate the additional water nozzle at the California Avenue Facility.
