Environmental Issues & Hazards
~10 min read · Handle lead paint (pre-1978), asbestos, radon and CERCLA liability at a listing.
Environmental issues enter every transaction through disclosure and liability: lead paint's federal pre-1978 regime, the asbestos/radon/mold inspection triad, and CERCLA's frightening rule that owning contaminated land can make you liable for cleaning it.
Lead-based paint: the federal regime
For residential housing built before 1978 (the year lead paint was banned), sales and leases require: the EPA/HUD disclosure form of known lead hazards, the pamphlet 'Protect Your Family From Lead in Your Home', and — for SALES only — a 10-day window for the buyer to conduct a lead inspection (waivable in writing). Agents share the compliance duty. Penalties for violations are per-occurrence and real. The rule is disclosure of KNOWN hazards — sellers need not test, only tell.
- Pre-1978 housing: disclosure form + EPA pamphlet
- Sales add a 10-day inspection right (waivable in writing)
- Disclose known hazards; testing is not required
- Agents are on the compliance hook too
The site-hazard roster
Asbestos: insulation/tiles in older buildings — dangerous when friable (crumbling, airborne); encapsulation is often safer than removal. Radon: odorless radioactive soil gas accumulating in basements — the #2 lung-cancer cause; measured in pCi/L, mitigated by ventilation systems; EPA action guidance at 4 pCi/L. Mold: moisture-driven; disclosure of known problems, remediation of the water source. USTs (underground storage tanks): leaking heating-oil and fuel tanks contaminate soil/groundwater. Wetlands and flood zones restrict building and trigger insurance requirements.
- Asbestos: friable = hazardous; encapsulate vs remove
- Radon: test, then ventilate; 4 pCi/L action guideline
- USTs and wetlands: site-level deal killers to flag
CERCLA and Superfund liability
CERCLA imposes cleanup liability that is strict (no fault needed), joint and several (any one party can owe the whole bill), and retroactive — reaching current owners, past owners at disposal time, generators, and transporters. The innocent landowner defense shelters a buyer who conducted all appropriate inquiries (the Phase I Environmental Site Assessment) before purchase and found nothing. Hence commercial practice: no Phase I, no closing.
Worked example
A buyer purchases (a) a 1972 duplex — the seller's agent skips the lead pamphlet 'because the paint looks fine' — and (b) a small commercial lot that, years later, turns out to sit over a 1980s dry-cleaner's solvent plume. The EPA bills the buyer for a $2M cleanup. Assess both messes.
The duplex: built pre-1978, so the machinery is mandatory regardless of paint condition — disclosure form, pamphlet, and the 10-day inspection right; 'looks fine' satisfies nothing, and both seller and agent face penalties, with the sale voidable exposure and liability if a child is later poisoned. The lot: CERCLA liability is strict, joint-and-several, and retroactive — CURRENT ownership alone puts the buyer on the responsible-party list for the historical plume. The escape he needed: the innocent landowner defense, which required all appropriate inquiries (a Phase I ESA) BEFORE buying; skipping it forfeited the defense. He can seek contribution from the dry cleaner's successors, but the EPA may collect the whole $2M from him first. Two properties, one lesson: environmental diligence is cheap only before closing.
Common exam pitfalls
Skipping lead compliance because paint is intact.
The trigger is the 1978 construction date, not paint condition — disclose, pamphlet, and offer the 10-day window.
Assuming innocence protects a polluted lot's buyer.
CERCLA is no-fault. Only pre-purchase all-appropriate-inquiries (Phase I) earns the innocent-landowner defense.
Ranking radon by smell or visibility.
Radon is odorless and invisible — testing is the only detection; ventilation mitigates.
'78 for lead, Phase I before the deed, and CERCLA bills whoever holds the land.
Recap
- Pre-1978 housing: lead disclosure + pamphlet + 10-day sale window
- Asbestos dangerous when friable; radon tested and vented
- USTs, wetlands, mold: site-level disclosure and diligence items
- CERCLA: strict, joint-and-several, retroactive cleanup liability
- Innocent-landowner defense requires pre-purchase Phase I inquiry
- Environmental diligence belongs before closing, always
