When it is appropriate, the City of Chicago will reuse soil and rubble instead of disposing of it in a landfill or quarry.  On March 13, 2009, the Chicago City Council approved the City entering into an intergovernmental agreement (IGA) with the Illinois Environmental Protection Agency (IEPA) for the reuse of soil and rubble generated by the City during City construction projects and reused in the city.  This IGA provides regulatory certainty for determining when it is appropriate to reuse soil and rubble.
