Summary:
The Committee on Energy and Environmental Protection held its final hearing of the session on April 17, 2026, and took up a series of Senate concurrent resolutions focused on environmental protection, waste reduction, and energy policy. Measures discussed included SCR 142 on dust monitoring near Waimanalo Gulch, SCR 39 on a mattress stewardship program, SCR 40 on banning disposable bodyboards, SCR 83 on a lithium-ion battery disposal facility, SCR 168 on a demolition waste reduction working group, SCR 96 on reporting on the Hawaii Electric Reliability Administrator, SCR 166 on PUC considerations for a generational energy commitment, and SCR 172 on a comprehensive analysis to reduce costs and financial risk while meeting state goals.
Testimony was generally supportive of the environmental and waste-management measures. The Department of Health supported SCR 39 and provided comments on SCR 142; Climate Protectors Hawaii supported SCR 39, SCR 83, SCR 168, and SCR 172; the Office of Planning and Sustainable Development and Hawaii Reef and Ocean's Coalition submitted comments or support on SCR 168; and the Public Utilities Commission provided comments on SCR 96 and SCR 166. On SCR 166, Greenpeace Hawaii testified in opposition to LNG, arguing it would worsen pollution and climate impacts, while Earthjustice supported the intent but suggested amendments. Earthjustice also supported SCR 172 and offered friendly amendments to improve the study language.
In decision-making, the chair recommended deferral of SCR 142 because an existing regulatory framework already addresses the issue. The committee then voted to pass SCR 39, SCR 40, SCR 83, SCR 96, and SCR 166 unamended. SCR 168 was passed with amendments to reflect OPSD's requested changes and to make the working group temporary, with a two-year term and annual reports due before session. SCR 172 was passed with amendments accepted from Earthjustice. Rep. Quinlan was noted as excused for the votes, and the committee adjourned after adopting the final recommendation.

Summary:
The hearing focused mainly on two subjects: expansion of the Massachusetts bottle bill and bills to remove woody biomass from state clean-energy and greenhouse-gas programs. On the bottle bill, supporters from municipal, environmental, public health, and local government groups argued that the 5-cent deposit is outdated, redemption rates have fallen, and expanding coverage to more beverage containers—especially water, sports drinks, and small alcohol bottles—would reduce litter, cut plastic waste and microplastics, and save cities and towns money. Several speakers also backed raising handling fees for retailers and redemption centers, and some supported restoring a Clean Environment Fund so unclaimed deposits would support recycling-related purposes. Opponents, including the Massachusetts Beverage Association and the National Waste and Recycling Association, argued that curbside recycling and transfer-station systems are more convenient, that the targeted containers are valuable to local recycling programs, and that the proposal would shift costs onto consumers and municipalities. Committee members questioned witnesses about redemption rates, handling fees, the 2014 ballot question, and whether the bill had changed from prior sessions.
The biomass portion drew strong support from Springfield officials, state legislators, environmental advocates, and public health groups. They said woody biomass should not count as clean energy because burning wood produces particulate pollution and carbon emissions, and they warned that current law contains a loophole that could help finance the proposed Palmer Renewable Energy biomass plant in Springfield. Witnesses emphasized Springfield’s air-quality and asthma burdens, the public health impacts of PM2.5, and the need to close the loophole before a January 1, 2026 deadline. One forest-industry witness supported a separate bill promoting modern wood heat with pollution controls, arguing it is cleaner than older wood systems and has minimal ratepayer cost, while noting that those credits would be affected if the governor’s broader energy affordability bill repeals the alternative energy portfolio standard.
No votes were taken during the hearing. The chairs managed testimony by alternating between the bottle bill and biomass topics, asking speakers to keep remarks brief and to note when they agreed with prior testimony. Several legislators also testified in support of the bills, and committee members asked follow-up questions on deposit levels, retailer handling fees, recycling economics, and the public-health rationale for the biomass restrictions.

Summary:
The Assembly Health Committee held an informational hearing on the health impacts of wildfires and the effects on health care systems and access to care. The first panel focused on public health consequences, with testimony from UCLA and UCSF physicians, a community organizer, and an Altadena recovery leader. Witnesses described acute and long-term physical harms from wildfire smoke and ash, including asthma and COPD exacerbations, cardiovascular and stroke risks, pregnancy impacts, infection risk, and possible added hazards from lithium-ion battery fires. They also emphasized mental health effects such as anxiety, depression, PTSD, “firebrain,” and the need for psychological first aid, trauma-informed community networks, and youth-focused resilience programs. Community advocates stressed that Latine, Indigenous, undocumented, and Black communities face disproportionate harm because of language barriers, unsafe work conditions, lack of insurance, and exclusion from disaster aid, and they called for stronger language access, worker protections, permanent disaster relief, and better outreach.
Committee members asked about air monitoring, masks, wind events, lithium-ion batteries, and how to reach communities with translation and emergency information. Panelists said AQI is useful but incomplete, that N95s help for smoke but P100 masks are needed for ash/asbestos exposure, and that communities should be warned to stay indoors and avoid windy dust-ups after fires. They also discussed the importance of building relationships during non-emergency periods, using text alerts and trusted community organizations, and providing culturally and linguistically appropriate information. Several members and witnesses highlighted the need for more research on long-term health effects, especially for people with chronic lung disease, workers who cannot stay indoors, and residents exposed to repeated disasters.
The second panel addressed health care system response and access to care. DHCS and DMHC described emergency flexibilities used during the Southern California fires, including federal waivers, extended Medi-Cal renewal deadlines, reinstated coverage for some disenrolled members, suspension of prior authorization and prescription refill barriers, out-of-network access at in-network cost-sharing, and communication through websites, toll-free numbers, and social media. Hospital and community health center leaders described major operational strain: emergency room surges, canceled surgeries, dialysis disruptions, staff displacement, temporary housing needs, and financial losses. Huntington Health and AltaMed reported using incident command systems, temporary care spaces, bilingual and culturally tailored services, mobile clinics, infection control measures, and community health workers to keep care going. Members and witnesses also discussed the need for better disaster staffing pools, more flexible facility rules, stronger mental health coverage, child care planning, and statewide coordination for future emergencies; no formal votes were taken.

Summary:
The Joint Committee on Public Health heard testimony on a wide range of bills focused on environmental health, disease prevention, and access to care. Major topics included restricting polystyrene use, creating a pancreatic cancer awareness and early-detection initiative, improving indoor air quality through a task force and new regulations, expanding access to epinephrine in public places, improving access to health care for people with long COVID, creating an OBGYN loan repayment program for underserved areas, expanding access to hygiene products, modernizing licensure for dietitians and nutritionists, updating school postural screening requirements, and restricting harmful diet pills and muscle-building supplements. Several legislators also testified in support of their own bills, including measures on menstrual product access and ingredient disclosure, and surgical smoke protections.
Testimony on the polystyrene bill emphasized local municipal bans and the need to reduce plastic pollution. Pancreatic cancer advocates and patients described the disease’s low survival rate, the difficulty of early diagnosis, and the need for an awareness campaign and implementation of commission recommendations. Indoor air quality supporters from environmental justice groups, public health organizations, and residents described asthma, mold, pollution, and the need for a task force with technical expertise; some witnesses urged adding remediation professionals to the task force. On epinephrine access, family members of a man who died after a bee sting and an allergy organization stressed that anaphylaxis can be sudden and fatal and that stock epinephrine in public venues could save lives. Long COVID advocates said the condition affects hundreds of thousands of residents and called for better surveillance and access to care, with a request to include MECFS in the bills’ scope.
Other testimony focused on workforce and equity issues. Supporters of the OBGYN loan repayment bill said it would help address maternal health disparities and provider shortages, especially in rural and underserved communities. Hope and Comfort described widespread hygiene insecurity and a long waiting list for basic products, urging a task force to study statewide solutions. Dietitians and nutritionists supported modernization of licensure to clarify standards for medical nutrition therapy while allowing broader wellness counseling. School nurses backed reducing mandatory postural screenings, arguing the current law is not evidence-based, is not reimbursed by MassHealth, and takes time from other student health needs. On the supplement bill, the industry trade group opposed restrictions as overbroad and burdensome, while a public health expert cited research linking weight-loss and muscle-building supplements to serious harms and urged passage. The committee also heard support for menstrual product access and surgical smoke protections, with legislators and advocates describing those bills as longstanding priorities.

Summary:
The Joint Committee on Public Health held a lengthy hearing to take testimony on a wide range of bills related to environmental health, PFAS, medical device chemicals, food access, lead poisoning, air quality, oral health, and school food additives. Chair Driscoll and Chair Decker emphasized that the hearing was for testimony only, no decisions would be made that day, and that written testimony could still be submitted. They also noted the high volume of speakers and asked witnesses to keep remarks brief.
A major portion of the hearing focused on PFAS-related legislation, including bills to restrict PFAS in products and food packaging and to create a PFAS remediation trust fund. Municipal officials and advocates described the high costs of PFAS cleanup, especially for drinking water systems, citing Easton’s multimillion-dollar treatment investments and rate increases. Testimony from legislators and advocates argued that Massachusetts should act despite federal uncertainty, and that the state should stop PFAS at the source rather than leaving municipalities and residents to pay for remediation. The committee also heard strong support for a bill banning DEHP in medical devices, with physicians, nurses, and a bill sponsor saying the chemical can leach from IV bags and tubing and that safer alternatives already exist.
The committee also heard testimony on bills to establish statewide food truck permitting, with food truck owners and a senator describing the current system as costly, duplicative, and inconsistent across municipalities. Another set of witnesses supported the “Bean New Deal,” which would expand plant-based food options in public institutions, senior nutrition programs, and WIC, citing health, equity, and cost savings. On lead poisoning, housing advocates and a representative backed bills to expand lead-safe housing requirements to all rental units, arguing the current law contributes to discrimination against families with children and leaves too much pre-1978 housing uncertified. The committee also heard support for an outdoor air pollution bill that would create an advisory committee, identify pollution hotspots, expand monitoring, and set reduction targets, with testimony from environmental justice groups, pediatricians, and legislators describing disproportionate asthma and other health harms in overburdened communities.
Later testimony addressed oral health bills to create dental therapists and allow dental hygienists to administer nitrous oxide, with supporters saying the measures would expand access, reduce costs, and help underserved patients. The committee also heard testimony on a bill to prohibit harmful food dyes in competitive school foods, with parents describing behavioral and health concerns tied to synthetic dyes. No votes or formal actions were taken during the hearing.

Summary:
The committee first heard House Bill 1904, which would classify intentionally released helium balloons as litter and create criminal penalties for balloon releases. The author and supportive witnesses argued that balloon releases harm wildlife, livestock, waterways, and infrastructure, and that the bill would close a loophole in current litter law. Several members questioned whether criminal penalties were appropriate, and the author said he was willing to work toward civil penalties and fines instead. No vote was taken, and HB 1904 was left pending.
The committee then took up several pending bills and reported them favorably to the full House, including HB 3249, HB 3866, HB 4112, HB 1768, HB 1499, HB 573, and HB 464. These measures dealt with topics such as TCEQ contested-case procedures, outdoor storage containers, high-level radioactive waste, concrete plant permitting and grants, unannounced concrete batch plant inspections, and a scrap tire grant program. Most were adopted with substitutes and passed on recorded votes, generally with unanimous or near-unanimous support.
A major portion of the meeting focused on HB 3997, which would create expedited permitting timelines for LNG facilities and related wastewater permits. Industry witnesses said the bill would provide certainty for multibillion-dollar projects without eliminating public participation, while environmental groups opposed parts of the bill that they said could limit contested-case participation and be unrealistic for SOAH timelines. TCEQ staff described the current wastewater permitting process and said some of the bill’s timing provisions could be workable, especially with an expedited fee. The bill was left pending after the author said he would continue working on committee substitute language.
The committee also heard HB 1237 on extending the renewal window for expired TCEQ occupational water licenses, and HB 4519, a TERP consolidation bill that would combine several clean transportation grant programs into fewer programs. HB 1237 was left pending without testimony, while HB 4519 drew broad support from environmental and industry witnesses who favored simplifying the program, though some asked for stronger emphasis on particulate matter and hydrogen funding. The committee withdrew the substitute on HB 4519 and left it pending. Finally, HB 5033, which would eliminate the motor vehicle emissions inspection and maintenance program if federal authority changes, drew opposition from environmental and inspection-industry witnesses who warned it would weaken air-quality protections and could remove an important enforcement tool. The author said the bill was intended as a trigger mechanism and would be refined, and HB 5033 was left pending. The committee also heard HB 1227 on municipal solid-waste franchise fees and private-provider access; the author said he would bring a substitute after hearing concerns from cities, and the bill was left pending.

Summary:
The committee hearing focused heavily on CARB’s broad trailer bill request for regulatory fee authority. Finance and CARB argued the proposal would let CARB develop fees to recover reasonable costs for implementing and enforcing regulations, while the LAO recommended rejection because the authority was too broad, could apply to an entire division of code, and would delegate core legislative taxing/fee-setting power without enough guardrails. Members from both parties raised concerns about the breadth of the authority, accountability, affordability impacts, and whether the Legislature would be put in an up-or-down position after CARB had already developed regulations. CARB responded that fees would still go through a budget change proposal and legislative approval before collection, and cited existing examples such as transport refrigeration units and commercial harborcraft fees.
The committee then reviewed CARB’s request for permanent resources to implement SB 905 on carbon capture, utilization, storage, and carbon dioxide removal. CARB said the Legislature had previously authorized limited-term positions and funding, but it had struggled to recruit and retain staff with specialized regulatory and technical expertise, and that the work had included pre-rulemaking contracts, technology review, and permit-related preparation. Members questioned the pace of work, the use of limited-term positions, and whether additional permitting authority would be needed. CARB said it hoped to begin rulemaking later in the year if permanent resources were approved.
Members also discussed the cap-and-trade spending plan, noting lower-than-expected auction revenues but higher interest earnings, and the need to monitor the Greenhouse Gas Reduction Fund and possible May Revision changes. The committee then heard overviews of the zero-emission vehicle package, the Community Air Protection Program, demand-side grid support, and e-bike incentives. CARB described ongoing investments in community-based transportation equity, drayage trucks, harbor craft, and other clean technology demonstrations, while members pressed on affordability, program duplication, and whether enough funding was being directed to incentive programs. No formal votes were taken during the portion provided, and the chair repeatedly indicated that the hearing was intended to surface concerns for later budget negotiations.

Summary:
The Assembly Natural Resources Committee met with some initial delay while waiting for quorum, then approved the consent calendar items SB 234, SB 484, and SB 839. The committee heard several bills focused on wildfire mitigation, biomass use, climate resilience, and geologic hazard mapping. Members and witnesses repeatedly emphasized the need to balance climate, air quality, public health, and land management goals, with testimony both supporting and opposing biomass-related proposals.
SB 88 (Caballero) would direct state agencies to support beneficial uses of forest and agricultural biomass, including biochar and low-carbon energy. Supporters argued it would reduce open burning, improve air quality, and create rural economic opportunities; opponents, including environmental groups, argued woody biomass energy is costly, polluting, and harmful to forests and communities. The bill passed as amended to Appropriations. SB 653 (Cortese) defining environmentally sensitive vegetation management also passed, with supporters describing it as a voluntary framework to align wildfire fuel reduction with biodiversity and habitat restoration; no opposition was heard, and a member requested to be added as a coauthor.
The committee also approved SCR 50 (Stern), which urges state climate agencies to define maladaptation and develop criteria for reviewing climate-related policies and investments, and SB 567 (Limón), a pilot program to study converting idle oil wells into gravity energy storage wells. SB 567 drew support from the sponsor and labor/local government witnesses, while the Water Replenishment District opposed unless amended, citing groundwater protection concerns in key basins and asking for additional safeguards. Finally, SB 831 (Limón) passed, clarifying the scope of geologic hazards to include conditions tied to climate change and natural disasters such as post-fire debris flows, subsidence, and coastal erosion. All measures were reported out of committee, with several absent-member votes later added to complete the roll.

Summary:
The committee hearing focused on a broad set of climate, energy, and environmental justice proposals. Early testimony strongly supported the Climate Change Superfund or “Polluter Pays” bill (H.1014/S.58), which would assess the largest fossil fuel emitters for a one-time fee based on historic emissions to fund climate adaptation. Sponsors argued the bill is modeled on Superfund cleanup principles, would target only the largest multinational polluters, would not be passed on to consumers, and would direct a significant share of funds to environmental justice communities. Committee members asked about the number of companies covered, consumer impacts, and whether the bill would address other forms of environmental destruction; sponsors said it was limited to major fossil fuel companies with a Massachusetts footprint and did not cover other pollution sources.
The committee also heard testimony on a fusion energy compact proposal (S.673) that would direct the administration to develop a framework for a New England regional compact to accelerate fusion research, workforce development, and supply-chain growth. Supporters from MIT and the Association of Independent Colleges and Universities said fusion could become a major clean-energy and economic opportunity, but acknowledged the technology is not yet commercially viable and still has unresolved technical, cost, and waste-management questions. Members pressed on environmental impacts, siting, waste, costs, and whether the bill would create a compact or only a framework; sponsors said it would only create the framework and that the administration would need to negotiate with other states.
Another major topic was a pilot program for nature-based climate solutions (H.971/S.??), backed by legislators, Boston Harbor Now, and UMass Boston’s Stone Living Lab. Witnesses said the bill would help speed permits for research and demonstration projects such as living shorelines, marsh restoration, and hybrid “green-to-gray” flood protections, while maintaining safeguards and protecting Indigenous and historic resources. Committee members asked how the proposal would interact with other permitting reforms and whether it could conflict with housing or wetland-related streamlining; supporters said it was complementary and aimed at making projects faster, more affordable, and more data-driven.
The hearing also covered climate-safe buildings and climate adaptation funding bills. Supporters of H.1004/S.583 said current building codes do not adequately account for future flooding, heat, and wind, and the bill would add climate expertise to the building board, allow stretch resilience codes, expand floodplain standards, and create a retrofit program. Related testimony backed H.938/S.572, which would create a dedicated climate and community resilience fund financed by a small fee on property insurance premiums; advocates said it would provide stable long-term revenue for adaptation, especially in environmental justice communities, and help replace unreliable federal funding. One witness from CLF supported the climate-safe buildings and funding bills but opposed S.560/H.939 as too broad. The committee also heard testimony on airport air-quality legislation (H.997) calling for more monitoring and mitigation of ultra-fine particulate pollution around Logan Airport and Massport communities. No votes were taken during the hearing.

Summary:
The committee took up House File 748, a bill revising Minnesota’s transportation greenhouse gas and vehicle miles traveled (VMT) impact assessment requirements for trunk highway projects. The chair first moved and adopted the A2 author’s amendment and then the A3 amendment, which was described as adding implementation time and project exemptions when federal dollars are available. The bill author explained that the measure responds to concerns from stakeholders that the current law can force costly mitigation, delay or stop safety and capacity projects, and create uncertainty because key implementation details are still being developed by a technical advisory committee.
Testimony was split. County and city engineers, county commissioners, the Minnesota Transportation Alliance, and the Coalition of Greater Minnesota Cities generally supported the bill, arguing that the current requirements can add 20% to 40% or more to project costs, are difficult to administer, and could jeopardize critical safety improvements, congestion relief, and federal funding. They cited examples such as Scott County and Trunk Highway 65, and said VMT mitigation is especially hard to quantify and fund. Opponents, including Move Minnesota and Sierra Club, argued that safety and climate goals are not in conflict, that reducing driving can save lives and reduce pollution, and that the bill would weaken an important tool for cutting transportation emissions. Members also asked about how GHG and VMT are measured, whether the required assessment was ready, and who would be responsible for mitigation assets and costs.
After discussion, the committee held a roll call vote. The bill, as amended, passed 8-7 and was moved to the General Register.
