Brownfield redevelopment in Massachusetts is regulated and overseen by the state under chapter twenty-one E, the “Massachusetts Oil and Hazardous Material Release Prevention Act.” Section (b)(3) of this chapter requires the state to provide technical assistance to municipalities, redevelopment authorities, redevelopment agencies, community development corporations, economic development and industrial corporations, and other persons interested in redeveloping brownfields. State brownfields program incentives are available to buyers, and sometimes sellers, of contaminated property provided there is a commitment to cleanup and redevelopment.
