Clean Soils

Uncontaminated soil is soil generated during construction, remodeling, repair or demolition of utilities, structures and roads that does not contain contaminants in concentrations above Illinois Environmental Protection Agency (IEPA) established Tiered Approach to Corrective Action Objectives (TACO) most conservative standards. TACO is the IEPA’s method for developing remediation objectives for contaminated soil and groundwater. These remediation objectives protect human health and take into account site conditions and land use. Remediation objectives generated by TACO are risk-based and site-specific. TACO provides flexibility to site owners and operators in developing site-specific remediation objectives.
