TL;DR
A clearance dust level is the maximum lead loading allowed on a surface after abatement or renovation, measured in micrograms of lead per square foot from a wipe sample. Current EPA limits are 10 µg/ft² for floors and 100 µg/ft² for interior window sills, with some states adopting stricter numbers.
What it means
A clearance dust level is the maximum lead loading allowed on a surface after abatement or renovation, measured in micrograms of lead per square foot from a wipe sample. Current EPA limits are 10 µg/ft² for floors and 100 µg/ft² for interior window sills, with some states adopting stricter numbers. A certified sampler collects wipes in each work area and a laboratory reports the results; the project cannot pass until every surface comes in under these thresholds.
