On June 21 the EPA released updated dust-lead hazard standards which reduce the acceptable levels from 40 μg per square foot to 10 μg per square foot for floors, and from 250 μg per square foot to 100 μg per square foot for window sills. The standards apply to most pre-1978 housing and child-occupied facilities, such as daycare centers and kindergarten classrooms. The EPA was ordered by the U.S. Court of Appeals for the Ninth Circuit to revise their standards by June 2019 after several environmental organizations sued the agency in 2016 for failing to update the standards.  The revised standards are expected to affect companies that restore structures built before 1978.
