Denver, CO, April 21, 2025 (GLOBE NEWSWIRE) — <\/p>\n

Colorado Hazard <\/p>\n

In early 2025, the Environmental Protection Agency (EPA) established new Dust Lead Action Levels (DLAL) and defined Dust Lead Reportable Levels (DLRL) for the first time\u200b. These changes replace the now defunct Dust Lead Clearance Standards (DLCS) and Dust Lead Hazard Standards (DLHS), that industry professionals have used for years.<\/p>\n

While dispensing with these terminologies will be impactful, this change in nomenclature is inconsequential compared to the significant reduction in the now Dust Lead Action Levels (DLAL). Lead abatement firms must clear their lead abatements at 5 \u00b5g\/ft\u00b2 for floors, 40 \u00b5g\/ft\u00b2 for interior windowsills, and 100 \u00b5g\/ft\u00b2 for window troughs: a more than 50% reduction. Furthermore, the Dust Lead Reportable Level (DLRL) (formerly the Dust Lead Hazard Standard or DLHS) has also been reduced from 10 \u00b5g\/ft\u00b2 on floors and 100 \u00b5g\/ft\u00b2 for windowsills to ANY REPORTABLE LEVEL. Confused yet? Let me clarify.<\/p>\n

The Health Dangers of Dust Lead<\/b><\/p>\n

The EPA sets standards for dust lead levels for a fundamental reason: Lead is a heavy metal that can damage nearly every system in the human body. Even low exposure levels can have significant consequences, and it is particularly harmful to children, whose growing bodies absorb it more readily.<\/p>\n

Children affected by lead exposure can experience developmental delays, learning disabilities, hearing problems, behavioral problems, and other issues. Lead can also affect adults, causing kidney damage, reproductive problems, nerve disorders, and cardiovascular problems.<\/p>\n

So, the need for regulations is clear. It is also essential that everyone from home and building owners to lead abatement companies understands the standards as they exist at the time work is performed.<\/p>\n

Tougher Lead Dust Standards<\/b><\/p>\n

Under the new EPA lead dust rule, any detectable amount is considered a hazard\u200b. In regulatory terms, the DLHS has been replaced with the DLRL, meaning any reportable lead level qualifies as a lead-dust hazard\u200b.<\/p>\n

Previously, the EPA\u2019s hazard thresholds were numeric. For example, a floor dust lead level below 10 \u00b5g\/ft\u00b2 previously was not deemed a hazard. Now, no amount of lead dust is considered \u201csafe\u201d from a hazard standpoint. This change aligns with the EPA\u2019s health research, which shows that even very low lead exposure can harm children.<\/p>\n

In practice, if a dust wipe sample finds even a small trace of lead, it must be reported as a lead hazard\u200b. This means any lead dust in a home is a concern, as there is no longer a threshold below which the EPA says, \u201cThis amount of lead is acceptable.\u201d<\/p>\n

Changes to Post-Abatement Lead Dust Standards<\/b><\/p>\n

Alongside the hazard definition change, the EPA has also dramatically tightened the allowable lead levels after an abatement. The DLAL refers to the dust lead concentrations that serve as the clearance criteria after abatement. They are now the new post-abatement clearance standards, and they have been markedly reduced to:<\/p>\n
