ILLINOIS ENVIRONMENTAL PROTECTION AGENCY

The Illinois Environmental Protection Agency specializes in the administration of air, water, and solid waste management programs under federal environmental statutes, with a focus on Superfund site remediation and regulatory compliance. Their core capabilities include implementing CERCLA response actions, managing hazardous waste site investigations, and enforcing environmental permitting frameworks for industrial and commercial sectors. Technical expertise spans environmental sampling and analysis, risk assessment modeling, groundwater remediation planning, and interagency coordination under the National Contingency Plan. A key differentiator is their deep familiarity with site-specific contamination profiles in complex industrial landscapes, particularly in legacy mining and chemical disposal areas, enabling targeted, science-driven cleanup strategies that align with EPA and DOI standards. The agency maintains a consistent working relationship with the Department of the Interior, primarily supporting environmental restoration and natural resource damage assessment activities at Superfund sites under CERCLA authority. They also collaborate with the Department of Justice on regulatory enforcement actions, particularly in permitting and compliance monitoring for state-issued water and hazardous waste programs, ensuring alignment with federal statutory requirements. Their primary industry focus is on environmental program administration, specifically NAICS 924110, which encompasses the operational execution of federally delegated environmental protection mandates. This includes oversight of hazardous waste permitting, air emissions compliance, and groundwater protection initiatives. The agency is positioned as a state-level implementer of federal environmental law, bridging regulatory policy with on-the-ground enforcement and remediation. As a state government entity structured as a 2A organization, the Illinois EPA operates under direct governmental authority with no private certifications. Based in Springfield, Illinois, it serves as the primary environmental regulatory body for the state and acts as a key partner to federal agencies in executing national environmental programs within its jurisdiction.
