Check out this excellent summary of the lead paint/RRP rule by Shawn McCadden.
The EPA RRP Rule and Your Business: On April 22, 2008, the EPA issued a rule requiring the use of lead-safe practices and other actions aimed at preventing lead poisoning. Under the rule, beginning in April 2010, contractors performing renovation, repair and painting projects for compensation that disturb lead-based paint in homes, child care facilities, and schools built before 1978 must be certified and must follow specific work practices to prevent lead contamination.
Decide to do the work or not: Make a conscience and informed business decision regarding your willingness to do the work and do it legally. If you choose to go forward, get your business and employees prepared. If you choose not to do the work, plan accordingly to replace the lost volume. If you choose to do the work illegally, be aware that the EPA will fine and or send to jail those who blatantly violate the rules.
