SECTION 2.

Chapter 21A of the General Laws, as appearing in the 2016 Official Edition, is hereby amended by inserting after section 18A, as Section 18B, the following section:-

The department of environmental protection, in consultation with the executive office of energy and environmental affairs and department of environmental health, shall convene a technical advisory committee comprised of: residents of environmental justice populations living adjacent to major highways; academics with expertise in air monitoring, environmental health, air toxics, and air pollution; and labor representatives; for the purpose of identifying communities with high cumulative exposure burdens for toxic air contaminants and criteria pollutants. The department shall convene the technical advisory committee by December 1, 2021. The technical advisory committee shall identify the likely air pollution hotspots due to high concentrations of traffic-related air pollution throughout the Commonwealth that should be equipped with new or expanded air monitors and establish a definition of “air quality” and “air quality target pollutants” that includes, but is not limited to, consideration of criteria pollutants, black carbon, and ultrafine particulate matter.

By June 30, 2022, the department of environmental protection shall install and operate air monitors in at least eight air pollution hotspots that measure for at least one of the following pollutants: black carbon, nitrogen oxides, ultrafine particulate matter. By December 31, 2022, the department of environmental protection shall establish baseline air quality in air pollution hotspots. Data from the air monitors shall be publicly accessible and provide near-time information. The department of environmental protection shall work with residents of environmental justice populations to conduct participatory action research where residents can use mobile air sensors to expand the number of locations where residents can track air quality.

Once those hotspots are determined and the baseline data is established, the department of environmental protection shall set annual targets to decrease air quality target pollutants between 2023 and 2035 to improve the air quality in that location. Air monitoring data shall be collected every three years between 2023 and 2035 to measure progress toward achieving air quality target pollutants reduction targets and make such data publicly available. By December 31, 2030, the department of environmental protection shall ensure that air pollution hotspots will have achieved air quality target pollutant concentrations that are at least 50 percent below the baseline in each hotspot and certify as such by publicly reporting compliance. By December 31, 2035, the department of environmental protection shall ensure that air quality target pollutants concentrations in hotspots are at least 75 percent below the baseline in each hotspot and certify as such by publicly reporting compliance. 

The department of environmental protection, in consultation with the department of public health, shall promulgate regulations for conducting indoor/outdoor assessments monitoring exposure to ultrafine particulate matter and black carbon particulate matter concentrations present in the indoor air of existing and proposed buildings, based on the best available science about the health risks associated with ultrafine particulate matter and black carbon. The department of environmental protection’s regulations shall at minimum set forth standard procedures for conducting air dispersion modeling, managing air pollution, monitoring ultrafine particulate matter, and estimating exposure.

The provisions of this chapter may be enforced by means of an action in the superior court seeking either injunctive relief, a declaratory judgment, a writ of mandamus or any combination thereof. No such action may be commenced without the plaintiff providing written notice of the violations of this chapter to defendants at least sixty (60) days prior to filing a legal action in superior court. All persons shall have standing to commence such enforcement actions.  Reasonable attorneys’ fees shall be recoverable by all substantially prevailing plaintiffs who seek relief under this section.

SECTION 3.

Section 26 of Chapter 111 shall be amended by adding the following section after the first paragraph:-
