Environmental disclosure

Environmental disclosure is not one universal form. It is the collection of property-condition statements, hazard-specific notices, known reports, government records, title instruments, and transaction documents that communicate environmental facts. In Illinois, a residential sale may involve the state seller report, a separate radon packet, a federal lead packet for covered pre-1978 housing, and property-specific records such as tank releases, cleanup letters, environmental covenants, or agency notices.

The current statutory report asks about unsafe drinking-water conditions, unsafe radon concentrations, unsafe asbestos concentrations or conditions, unsafe lead conditions involving paint, water pipes, plumbing pipes or soil, mine subsidence and related earth-stability defects, underground fuel storage tanks, and notices of violation. Floodplain and flooding questions can also affect environmental and land-use analysis. The seller answers from actual notice or actual knowledge without a required specific investigation.

No. The Residential Real Property Disclosure Act requires disclosure of material defects the seller actually knows and states that the seller need not make a specific investigation or inquiry to complete the report. That does not permit concealment or an untrue answer. It also does not prevent a buyer, lender, insurer, agency, or contract from requiring testing, records, due diligence, or correction.

No. The general report includes a radon question, but the Illinois Radon Awareness Act creates a separate transaction packet for covered sales. Before the buyer is obligated, the seller provides the IEMA-approved pamphlet and the statutory radon disclosure, including information in the seller's possession about test results showing elevated levels. The Act does not require the seller to test or mitigate solely because of that disclosure duty.

No. For most pre-1978 housing sales and leases, federal law separately requires the approved lead pamphlet, known lead information, available records and reports, warning and acknowledgment language, certifications, signatures, and dates before obligation. In a covered sale, the buyer ordinarily gets a 10-day opportunity for a lead inspection or risk assessment unless changed or waived in writing. Illinois seller-report item 17 remains a separate duty.

A Phase I environmental site assessment is a professional inquiry into past and present property uses and environmental conditions. It commonly uses historical sources, government records, interviews, a visual inspection of the property and adjoining properties, land and cleanup records, and an environmental professional's report. It generally does not include invasive sampling. For federal All Appropriate Inquiries, ASTM E1527-21 and E2247-23 are currently recognized as consistent standards.

Phase I identifies recognized environmental conditions through records, history, interviews, observation, and professional judgment. Phase II generally uses targeted sampling and laboratory analysis to evaluate a suspected condition, such as soil, groundwater, vapor, or building-material contamination. A Phase I finding can support a recommendation for further investigation, but the exact Phase II scope should be designed by qualified environmental professionals for the property and proposed use.

EPA states that AAI must be conducted or updated within one year before acquisition. Interviews with current and past owners, review of government records, the on-site visual inspection, and searches for environmental cleanup liens must be conducted or updated within 180 days before acquisition. The dates run to acquisition, not merely contract signing or the date a lender first reviewed the report.

No. A Phase I is an inquiry performed within a defined scope and with stated limitations, not a warranty that every contaminant is absent. Data gaps, inaccessible areas, timing, non-scope conditions, historical-source limits, and conditions not reasonably observable all matter. EPA identifies radon, lead-based paint, mold, asbestos, and indoor air quality as examples of additional services that can fall outside the federal AAI scope unless separately included.

CERCLA can impose strict liability on current owners and operators for hazardous-substance cleanup even without proof of negligence. Liability can also be retroactive and, where harm is indivisible, joint and several. Certain buyers may seek innocent-landowner, contiguous-property-owner, or bona fide prospective purchaser protection, but the statutory criteria require more than purchasing an environmental report. AAI before acquisition and continuing obligations after acquisition are central.

EPA identifies duties such as no post-acquisition disposal, compliance with land-use restrictions, protection of institutional controls, reasonable steps concerning existing releases, cooperation and access for response work, responses to information requests and subpoenas, and legally required notices. A buyer cannot preserve potential landowner protection by completing a Phase I and then ignoring a release, recorded restriction, cap, groundwater prohibition, or access request.

An Illinois EPA No Further Remediation Letter means the site met the requirements and applicable cleanup objectives of the program and incident addressed by the letter. It can rely on land-use assumptions, engineered barriers, or institutional controls and may need recording. It does not necessarily mean the property is pristine, suitable for every future use, free of every contaminant, or outside every other regulatory program. Read its exact site, incident, conditions, exhibits, and recording information.

An Environmental Land Use Control, or ELUC, is an institutional control that places contamination-related restrictions or requirements in the chain of title. Examples include prohibiting potable groundwater use, limiting the property to industrial or commercial use, maintaining an engineered barrier, or following a construction-worker safety plan. A buyer must understand the control's location, prohibited activities, maintenance, access, reporting, and effect on the proposed use.

No. The practice questions are original. The PSI Illinois outline, current Illinois disclosure and radon statutes, current federal lead regulations, EPA CERCLA and AAI guidance, and Illinois EPA cleanup-program materials were checked through August 1, 2026. This is exam education, not legal, engineering, environmental, medical, insurance, or lending advice. A live property requires qualified counsel, an environmental professional, current agency and title searches, and a transaction-specific scope.
