IERG’s primary objective is the development and negotiation of environmental regulations and laws in Illinois. IERG is committed to the principle that environmental regulation and policy be grounded on sound science and produce demonstrated environmental improvements commensurate with the costs involved for compliance.

Because of the diversity of these regulations – and the way in which responsibilities are spread over state government – IERG is involved with an ever expanding universe of state agencies and departments. To this end, IERG expends effort to actually draft both regulatory language and detailed comments on proposals put forth by the regulatory agencies. On behalf of IERG members, staff is involved early in the effort to provide sound and technically defensible input throughout the regulatory, policy or legislative process.
