Mass. Gen. Laws ch. 59 § 59A
Municipalities may establish, relative to sites or portions of sites from or at which there has been a release of oil or hazardous material, an agreement between the city or town and any eligible person, as defined in section 2 of chapter 21E, regarding the abatement of outstanding real estate tax obligations, interest and costs on said sites or portions of sites; provided, however, that said sites or portions of sites are zoned for commercial or industrial uses by the municipality in which said sites or portions of sites exist. Such agreement, for the purpose of continuing environmental cleanup on such sites and redevelopment in such communities, shall include, but shall not be limited to, the amount outstanding, the per cent of interest to accrue if determined applicable by the parties, the description of quantifiable monthly payments, the inception date of such payments, the date of the final payment, late penalties, and any other contractual obligations arranged between the parties. The terms of repayment shall be set at the discretion of the municipality and shall be included in the agreement between the parties. A city or town that accepts this section shall adopt an ordinance or by-law specifying the method for negotiating and approving agreements under this section. Copies of each such agreement shall be signed by the municipal officer required by the ordinance or by-law and by the owner of the property in question, notarized, attested to by the city or town clerk, and provided to the department of environmental protection, the federal Environmental Protection Agency, the city council or board of selectmen, and the owners of the property in question. This section shall take effect in any city or town only upon its acceptance by such city or town.
