As of April 22, 2010 anyone that renovates and disturbs lead based paint in a home, school, or child care facility must be certified and know the good practices to prevent lead contamination.
Also, beginning April 2010, federal law will require contractors that disturb lead-based paint in homes, child care facilities and schools, built before 1978 to be certified and follow specific work practices to prevent lead contamination. Therefore beginning in April 2010, ask to see your contractor’s certification.
"The NAHB says that a shortage of Environmental Protection Agency (EPA) accredited trainers may stall some remodeling projects in homes where lead is present. A new regulation by the U.S. EPA went into effect last month (April 22, 2010) that requires all contractors working in homes built before lead paint was banned in 1978 to be trained and certified under the Lead Paint: Renovation, Repair, and Painting Rule (LRRP).
The purpose of the regulation is to reduce the potential exposure to lead paint that may occur when a home that was built before 1978 is remodeled. The regulation isn't limited to just remodelers. Other contractors who must become certified include carpenters, plumbers, heating and air conditioning workers, and window installers. The NAHB is sending out a word of caution, since the EPA has approved only 135 training providers and certified about 14,000 renovators in lead-safe work practices. However, according to NAHB, the EPA's own estimates indicated that more than 200,000 contractors must be trained and certified"
