On June 24, 2020, EPA published a proposal to lower its current dust-lead clearance levels (DLCL) from 40 micrograms of per square feet (ug/ft2) to 10 ug/ft2 for floors and 250 ug/ft2 to 100 ug/ft2 for window sills. DLCL is the maximum amount of lead permitted in dust on a surface after the completion of an abatement activity. Lab analysis of surface dust collected post-abatement must be below these clearance levels. The proposed reduced DLCL levels mimic the dust-lead hazard standards (DLHS) EPA revised in 2019. The DLHS identify dust-lead hazards while the DLCL demonstrate the permanent elimination of those dust-lead hazard levels via abatement.
Comments are due on August 24, 2020.
