RRP compliance for Massachusetts contractors is turning out to be a real dilemma. As of this date according to the State RRP License list their are only 3300 entities who can legally offer to work or work on pre 1978 properties. Of the 3300 or so companies there are many who are not contractors. I have not counted the amount of contractors on the 154 pages on the list but I would take an educated guess that there are less than 2500 contractors who are RRP legal according to the Mass RRP Lead Law. As of July 2010 when the state took over the law there were 4500 contractors on the EPA Certified Firm List. How come they all didn't convert to the Mass License? Mass allows a waiver and no fee if you were already certified with the EPA. Answer: OSHA Lead in Construction Standards written int the Mass RRP Law.
