Hazard Standards and Clearance Levels for Lead in Paint, Dust and Soil (TSCA Sections 402 and 403)
On June 17, 2020, EPA announced a proposal to reduce the amount of lead that can remain in dust on floors and window sills after lead removal activities to protect children from the harmful effects of lead exposure. The agency's proposal would lower the amount of lead that can remain in dust on floors and window sills after lead removal activities from 40 micrograms (µg) of lead in dust per square foot (ft2) to 10 µg/ft2 for floor dust and from 250 µg/ft2 to 100 µg/ft2 for window sill dust.
The proposed, tighter standards would increase the effectiveness of work done to remove lead-based paint hazards in pre-1978 homes and childcare facilities, known as abatement, and lower the risk of lead exposure by ensuring that lead-based paint hazards are effectively and permanently eliminated following completion of the work. This action is an important step to reduce exposure to lead sources and directly supports the December 2018 Federal Action Plan to Reduce Childhood Lead Exposures and Associated Health Impacts.
EPA is accepting public comments on its proposal to strengthen the dust-lead clearance levels for 60 days following publication in the Federal Register. To view the proposed rule, or for additional information, please visit EPA-HQ-OPPT-2020-0063.
On June 21, 2019, EPA announced new, tighter standards for lead in dust on floors and window sills to protect children from the harmful effects of lead exposure. The standards were lowered from 40 µg of lead in dust per ft2 on floors and 250 µg of lead in dust per ft2 on interior window sills, to 10 µg/ft2 to 100 µg/ft2, respectively. The strengthened standards become effective 180 days after publication in the Federal Register. The lead hazard standards help property owners, lead paint professionals, and government agencies identify lead hazards in residential paint, dust and soil. The DLCL are used to demonstrate that abatement activities effectively and permanently eliminate those hazards. They apply in most pre-1978 housing and child-occupied facilities.
The hazard standards are incorporated into the Section 402/404 lead-based paint activity regulations. In addition, lead-based paint hazards trigger reporting obligations under the Section 1018 real estate disclosure regulations. Please refer to those regulations for information on compliance requirements regarding these hazard standards.
