"EPA is proposing new lead-dust standards to significantly lower acceptable levels for the first time in 17 years.

The proposal would quarter the acceptable lead-dust level for floors from 40 to 10 micrograms per square foot and more than halve the acceptable levels for window sills from 250 to 100 micrograms per square foot.

Those levels would bring EPA standards in line with those at the Department of Housing and Urban Development.

The newly proposed standards follow a January federal appeals court ruling that EPA had illegally delayed updating its lead dust regulations, which had been unchanged since 2001."
