Reconsideration of the Dust-Lead Hazard Standards and Dust-Lead Post-Abatement Clearance Levels

Zusammenfassung

As part of EPA's high-priority efforts to reduce childhood lead exposure, and in accordance with a U.S. Court of Appeals for the Ninth Circuit 2021 opinion, EPA is finalizing its proposal to lower the dust-lead hazard standards to any reportable level as analyzed by a laboratory recognized by EPA's National Lead Laboratory Accreditation Program (NLLAP). EPA's lead-based paint (LBP) regulations do not compel property owners or occupants to evaluate their property for LBP hazards or to take control actions, but if a LBP activity such as an abatement is performed, then EPA's regulations set requirements for doing so. EPA is also finalizing changes to lower the post-abatement dust-lead clearance levels to 5 micrograms per square foot ([micro]g/ft\2\), 40 [micro]g/ft\2\, and 100 [micro]g/ft\2\ for floors, window sills and troughs respectively, the current levels in New York City. Due to feedback from public comments, EPA is also finalizing changes to the nomenclature to adopt the terms dust-lead reportable levels (DLRL) and dust-lead action levels (DLAL). Given the decoupling of the action levels from the reportable levels, EPA is finalizing revisions to the definition of abatement so t
