Please Note: The mercury lamp provisions of the Massachusetts Mercury Management Act (M.G.L. Chapter 21H) were amended by Chapter 196 of the Acts of 2014, which was signed on July 30, 2014. This amendment deleted Sections 6J(d) and (e) of the law as of October 28, 2014. As a result, certifications that mercury lamp manufacturers were required to submit to MassDEP before that date are no longer required. As MassDEP develops a plan for implementation of the new requirements, information will be posted here and made available to mercury lamp manufacturers and others who will have new responsibilities under the new law. If you have questions, contact Suzi Peck: 617-292-5870 or
