On Friday September 20, 2019, beginning at 8:30am, near I-290 & Vallette, NICOR will be performing the grouting of a recently abandoned 20” gas main. This work will include injecting product into the abandoned main. Along the existing haul road, north of St. Charles and east of Park Avenue, pressure relief purge stacks will allow the grout product to move. This technique/work may cause an odor while we perform this task. Local schools and residents will be advised of the potential odor during this operation tomorrow. Residents should not be concerned with this process, as it is safe, highly controlled, and necessary for this project.
