What are the dust-lead hazard standards and dust-lead clearance levels now called?

Answer: Due to feedback from the public comments, EPA finalized changes to the nomenclature, from dust-lead hazard standards (DLHS) to dust-lead reportable level (DLRL) and from dust-lead clearance levels (DLCL) to dust-lead action level (DLAL). EPA believes this updated nomenclature aligns better and more intuitively with the operational function of the amendments EPA finalized in the November 12, 2024 final rule entitled “Reconsideration of the Dust-Lead Hazard Standards and Dust-Lead Post-Abatement Clearance Levels” (89 FR 89416), which is effective January 13, 2025. For example, the new terminology makes it clear that if a dust-lead loading falls below the DLAL but above the DLRL, then dust-lead is still present in the environment, but the levels are below those prioritized for action.
