title: Hazardous Material Abatement

### The survey shall identify, locate, and quantify all suspect ACM, LBP, and PCB-containing materials in the renovation or demolition area.
−### Suspect materials not sampled shall be presumed regulated and abated as such, or sampled and analyzed before the work that would disturb them.
−
−### Bulk ACM samples shall be analyzed by polarized light microscopy (PLM) with point counting for results near the 1% regulatory threshold.
−
−### Paint and coatings shall be tested for lead by XRF in place or by laboratory analysis of bulk samples.
−
−### Caulk, sealant, and glazing-compound samples shall be analyzed for PCB concentration by laboratory method before any window-replacement or facade work in buildings constructed or renovated before 1980.
−
−## Pre-1980 curtain-wall and window assemblies are a recurring PCB blind spot: glazing compounds and perimeter caulk in these assemblies frequently exceed the 50 ppm TSCA threshold, and discovering that mid-project halts the window contractor and triggers a TSCA compliance crisis. {note}
−
−## A material is asbestos-containing when it contains more than 1% asbestos by PLM; a coating is lead-based paint at 1.0 mg/cm² by XRF or 0.5% (5,000 ppm) by laboratory analysis; caulk or sealant is TSCA-regulated PCB material at 50 ppm or greater. {note}

# Regulatory Notification {toc}
…4 unchanged lines
### The Contractor shall submit written NESHAP notification to the EPA or delegated state agency at least 10 working days before the start of any regulated renovation or demolition.
−### Notification shall be filed whenever the quantity of regulated ACM meets or exceeds any one of the NESHAP thresholds, and for all demolitions regardless of ACM quantity where the jurisdiction requires it.
−
−### The Contractor shall obtain and maintain all applicable state and local abatement permits before mobilizing.
−
−### Where an emergency renovation operation qualifies under the NESHAP imminent-hazard exception, the Contractor shall document the emergency and notify the agency as soon as practicable.
−
−## Demolition and renovation also trigger separate state asbestos-project and lead-project notifications in most jurisdictions; the federal NESHAP notice does not satisfy them. {note}

### Lead-safe interim work under the RRP Rule shall be performed only by a certified renovation firm using certified renovators under 40 CFR 745 Subpart E.
−## Abatement and the RRP Rule are legally distinct and must never be conflated in scope: abatement permanently eliminates the lead hazard and requires a certified abatement firm, while RRP is an interim lead-safe work practice by a certified renovator — specifying one and licensing for the other creates a liability and licensing gap. {note}

## Worker fit-testing, medical surveillance, and exposure monitoring are not paperwork to be assumed away: OSHA requires these records to be created and retained for 30 years for asbestos and for the duration of employment plus 40 years for lead, and the Owner must confirm the Contractor operates the program rather than presuming it exists. {note}

## Encapsulation is compliant only where the ACM will remain in place and intact: friable ACM scheduled for demolition cannot be encapsulated in lieu of removal, because demolishing encapsulated friable ACM still requires NESHAP-compliant removal first. {note}

### Post-abatement lead dust-wipe clearance shall be sampled and analyzed by an NLLAP-certified laboratory.
−## The lead dust-wipe clearance levels are the 2024 HUD/EPA values — floors no greater than 10 µg/ft², interior window sills no greater than 100 µg/ft², and window troughs no greater than 400 µg/ft²; the floor limit was reduced from 40 to 10 µg/ft² and the current value must be used. {note}

# PCB Caulk and Sealant Abatement {toc}
−## PCB-containing caulk and sealant removal under TSCA is self-implementing: the contractor prepares an abatement plan, removes the material with continuous dust capture, and routes the waste to an approved facility — there is no agency pre-approval, only a documented procedure the contractor must follow correctly. {note}

## The concentration determines the obligation: caulk or sealant at 50 ppm or greater is fully TSCA-regulated, material at 2 to 50 ppm is treated as low-concentration PCB, and material below 2 ppm is non-regulated. {note}
