|TACO is the Illinois EPA'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.
Previously, the Illinois EPA's Bureau of Land (BOL) used conservative
"one-size-fits-all" remediation objectives at nearly every site.
Baseline remediation objectives still exist, but other options also
protective of human health have been added.
TACO provides flexibility to site owners and operators in developing
site-specific remediation objectives. It's now the site owners and
operators who decide how best to manage their sites within TACO
guidelines. However, this determination of site-specific remediation
objectives is subject to Illinois EPA review and approval.
By exercising these new choices, site owners and operators may reduce
remediation costs, return more sites to productive use, hasten property
redevelopment, and still fully comply with environmental laws and
