Section 1 of Chapter 111 of the General Laws, as appearing in the 2018 Official Edition, is hereby by adding the following definitions:- “Continuous automated sampling system” means the total equipment and procedures for automated sample collection, sample recovery and analysis to determine an air contaminant concentration or emission rate by collecting a single sample or multiple integrated samples of the air contaminant for subsequent on- or off-site analysis. “Continuous emissions monitoring system” means a monitoring system for continuously measuring the emissions of an air contaminant from an incinerator. “Dioxin/furan” means tetra- through octa-chlorinated dibenzo-p-dioxins and dibenzofurans. “Hospital, medical or infectious waste” means hospital waste or medical/infectious waste, as defined in any general law or regulation in effect on the effective date of this act. “Municipal solid waste incinerator” means any facility operated before, on or after the effective date of this act for the purpose of combusting municipal solid waste, regardless of whether the facility is later reclassified as another type of waste combustion facility.
(a) Section 150A of said chapter 111 of the General Laws, as so appearing is amended by adding the following:- “The owner or operator of a municipal solid waste incinerator shall develop a plan to continuously monitor or sample emissions of the following: carbon monoxide and sulfur dioxide and nitrogen oxides and opacity and PCB and dioxin/furan and cadmium and lead and mercury and arsenic and total chromium and manganese and nickel and selenium and zinc. (b) Where technologically feasible, the plan must provide for the use of a continuous emissions monitoring system to monitor the air contaminants described in paragraph (a) of this subsection. (c) If it is not technologically feasible to use a continuous emissions monitoring system to monitor an air contaminant described in paragraph (a) of this subsection, the plan must provide for the use of a continuous automated sampling system to continuously sample that air contaminant.” (d) The plan must describe how the owner or operator will conduct continuous monitoring or sampling required by this section for a period of 12 consecutive months; and make emissions data available to the department and the public.” (e) The owner or operator of a municipal solid waste facility must submit the plan required by this section to the department no later than three months after the effective date of this act. Before approving the plan, the department may make such modifications to the plan as necessary to ensure the quality and accuracy of sampling or monitoring data. (f) The owner or operator of a municipal solid waste incinerator must implement a plan approved by the department no later than three months after the date of approval.” (g) Notwithstanding subsection (e) of this section, the department may at the department’s discretion, for good cause shown, extend the three-month deadlines for submitting or implementing the plan required by this section.” (h) A municipal solid waste incinerator may not combust more than 18,000 tons of hospital, medical or infectious waste during a single calendar year. (i) The department shall take all reasonable steps to ensure that any permit issued under the federal operating permit program established under is modified to be consistent with section 3 of this act within 12 months of the effective date of this act. (j) No later than one year after the effective date of this act, the department shall submit a report on the progress made in implementing section 2 of this act, including data received by the department, in the manner provided in regulation. (k) No later than three months after the completion of the 12-month period required by section 2 of this act, the department shall submit a report on the results of the continuous monitoring or sampling conducted under section 2 of this act, in the manner provided in regulation.”
