Those on the Argonne site may hear loud popping sounds from the south on Wednesday, Oct. 9, 2019, as U.S. Department of Agriculture (USDA) employees conduct firearms qualification. In conjunction with the Illinois Department of Natural Resources, USDA employees will use a firearms range on the extreme south end of the Argonne site from approximately 10 a.m. to 3 p.m.
Argonne Security and the Fire Department have been notified, and a safety plan is in place that includes warning signs and road barricades.
Depending on the weather conditions, this firearms training may be louder than the occasional popping coming from the Lemont Police Department firearms range along the Des Plaines River south of the site.
