Overview of Brownfield Remediation Steps

Typical remediation on redeveloping properties in Chicago follows assessment, investigation, remedy selection, implementation, and verification. Developers commonly engage environmental consultants for Phase I and Phase II investigations, then submit recommended remedial actions to the state remediation program for oversight and No Further Remediation determinations where applicable.[1]

  • Phase I Environmental Site Assessment to identify potential Recognized Environmental Conditions.
  • Phase II Investigation including soil, groundwater, and vapor intrusion testing.
  • Remedy selection and workplan preparation for submission to the oversight authority.
  • Implementation of remediation (excavation, treatment, controls) under an approved plan.
  • Verification sampling and documentation to demonstrate cleanup objectives are met.

Penalties & Enforcement

Primary oversight for site remediation in Illinois is the Illinois Environmental Protection Agency Remediation and Redevelopment Program; local inspections and nuisance enforcement may be undertaken by Chicago departments depending on the issue. Specific monetary penalties, citation procedures, and escalation ranges are not specified on the cited Illinois EPA program page.[1] For local complaint intake and inspection requests contact the Chicago Department of Public Health or the Department of Buildings for construction-related compliance.[2]

  • Monetary fines: not specified on the cited page.
  • Escalation: first, repeat, and continuing offences: not specified on the cited page.
  • Non-monetary sanctions: orders to cease work, corrective orders, and possible court actions may be issued by enforcing agencies.
