Summary:
The joint Senate and Assembly Environmental Quality/Environmental Safety and Toxic Materials informational hearing focused on the Tijuana River Valley sewage crisis, with members from both parties emphasizing that the problem is long-running, cross-border, and severe enough to require federal, state, local, and binational action. Opening remarks described the crisis as an environmental and public health emergency affecting beaches, air and water quality, marine life, tourism, and residents’ quality of life in South Bay communities. Assembly Member Boerner and Senator Jones both stressed the need for continued funding and cooperation, while Senator Padilla said the issue is underappreciated because of where it occurs but has major public health, economic, and educational consequences. Congressman Mike Levin’s office reported more than $650 million in federal funding secured for infrastructure and cleanup, along with federal legislation and requests for CDC and EPA involvement.
Supervisor Paloma Aguirre gave a detailed overview of county efforts and the scope of the crisis, citing decades of sewage flows from Tijuana, nearly four years of beach closures, and the county’s expanded water-quality monitoring. She said the county is pursuing warning signs, an air purifier distribution program, an epidemiological study, soil testing, an economic impact study, and a feasibility analysis to remove the “hot spot” near Saturn Boulevard, which she described as a key local source of airborne pollution. She also pointed to binational funding for treatment plant upgrades and said the county is seeking state support, including from Proposition 4 cross-border river funds, to expand relief and mitigation efforts.
Scripps researchers Dr. Sarah Giddings and Dr. Kimberly Prather presented scientific findings on water and air transport. Giddings described a high-resolution forecast model that predicts wastewater movement and beach closure risk up to five days ahead, using real-time observations and showing about 72% accuracy against county measurements. Prather said the main exposure route is through air, not just water, and reported that turbulence at the river hot spot aerosolizes pollutants, with hydrogen sulfide and other gases spiking at night and dropping when river flow is diverted. She said the team has identified thousands of gases and linked measurements closely to odor complaints, while also noting that air purifiers can reduce indoor exposure but are not a permanent solution.
Dr. Paula Stigler Granados added that community health surveys and CDC assessments show widespread symptoms, sleep disruption, anxiety, and daily life impacts, especially during nighttime odor events. She said her team has found more than 900 contaminants in river water and 106 chemicals uniquely associated with the Saturn Boulevard hot spot, with passive air sampling showing similar chemical fingerprints in nearby homes. The panel discussion ended with questions about standards and accountability, and witnesses and legislators agreed that the crisis requires updated air-quality standards, more health research, and continued coordination to reduce exposure and address the source of pollution.

Summary:
The committee heard several bills, with SB 1350 by Senator McNerney presented first. The measure would expand California’s use of renewable hydrogen in the power sector by allowing renewable portfolio standard credit for power plants using green hydrogen, with supporters emphasizing grid reliability, clean-energy goals, in-state investment, and construction jobs. Support came from labor, clean-energy, municipal utility, and local government representatives; NRDC Action Fund withdrew opposition after amendments, while a few groups remained opposed or neutral. The committee later took a roll call and SB 1350 passed out on a due pass recommendation.
The committee also heard SB 1180 by Senator Allen, which would set operational rules for the Plastic Pollution Mitigation Fund created under SB 54, including clearer eligible uses, transparency, technical assistance, and access for tribes and smaller community groups. Environmental justice, ocean, conservation, and local government groups strongly supported the bill, saying it would ensure the fund addresses plastic pollution’s public health and environmental harms. Industry and manufacturing groups opposed unless amended, arguing the bill should stay tightly tied to plastic waste reduction and not broaden into source-reduction policy. After quorum was established, the committee approved SB 1180 on a due pass recommendation to Appropriations.
SB 1326 by Senator Wahab was then heard to strengthen tribal consultation and tribal cultural resource protections under CEQA by recognizing tribal registers and requiring feasible avoidance or mitigation measures when tribes identify resources. Tribal representatives and supporters said the bill would better protect sacred sites and tribal knowledge, while cities, counties, utilities, builders, and rural county groups opposed unless amended, citing implementation concerns, possible litigation, and uncertainty for infrastructure and housing projects. The committee voted the bill out on a due pass recommendation to Appropriations.
Finally, SB 954 by Senator Blakespear was presented as a cleanup of last year’s SB 131 advanced-manufacturing CEQA exemption, narrowing eligible projects and adding guardrails such as setbacks, air-quality limits, tribal consultation, labor standards, and habitat protections. Environmental and labor groups supported the bill as a needed correction to an overly broad exemption, while business, manufacturing, housing, and local-government groups opposed, warning it could make the exemption unusable and slow investment. Members debated the balance between environmental protection and manufacturing competitiveness, and the committee voted SB 954 out on a due pass recommendation to the Labor and Employment Committee; the transcript then moved on to SB 1031 on compostable plastics, which was introduced but not acted on in the portion provided.

Summary:
The committee met with a quorum present to hear Article VI Natural Resources agency budget recommendations, beginning with the Railroad Commission. LBB staff summarized the commission’s 2026-27 base recommendation at $458.7 million, down from the prior biennium, with an increased FTE cap. The presentation highlighted reduced federal IIJA funding, volatility in oil and gas regulation account 5155, continued support for IT modernization, and rider changes. The commission’s major exceptional items were then presented, including requests for produced water and injection data reporting, an authorized pit registration system, regulatory filing/permitting upgrades, an underground injection well investigation team, site remediation support, and especially $100 million for orphan well plugging. Members asked about biennium-to-biennium comparisons, salary biennialization, the scale of orphan well risks, federal funding delays, bonding, and whether the state should rely more on industry or general revenue for plugging costs. Commission leadership explained that orphan wells can threaten water and public safety, that plugging costs have risen sharply, and that current funding is insufficient to keep up with emergency wells and the backlog; they also said the agency is moving to cloud-based systems with cybersecurity protections and that the proposed performance measure may need adjustment if funding does not increase.
The Railroad Commission testimony was followed by LBB and agency testimony for the Texas Animal Health Commission. LBB described a $42 million recommendation for 2026-27, an increase overall, but with a reduced FTE cap due to turnover and salary reallocation. The recommendation maintained funding for cattle fever tick work, chronic wasting disease, lab testing through an MOU with Texas A&M’s veterinary diagnostic lab, and a new $5 million spay-and-neuter pilot program, while deleting a capital budget rider and adjusting riders tied to entry point inspection stations and clinical trials. Agency leadership then outlined the commission’s mission to protect livestock health and the state’s $22 billion animal industry, and described major disease threats including highly pathogenic avian influenza, cattle fever ticks, New World screwworm, and chronic wasting disease. Their exceptional items focused on recruiting and retaining veterinarians, replacing fleet vehicles, creating an ectoparasite identification lab, adding field staff and IT support, improving records and epidemiology reporting, strengthening central administration, supporting secure food supply planning, expanding chronic wasting disease work, and staffing the new spay-and-neuter program. Members asked about field identification of ticks, the use of disinfectants and PPE, fleet management, the scale of cattle fever tick risk, and chronic wasting disease; the agency explained its current inspection and lab-confirmation process, its reliance on field disinfecting and biosecurity, and the need for more staff and better data systems to keep pace with growing workloads and disease threats.

Summary:
The joint Committee on Energy and Intergovernmental Affairs and Committee on Transportation, Culture, and the Arts heard several resolutions, with most public testimony focused on Senate Concurrent Resolution 159 and Senate Resolution 129, which urge continued U.S. support for the Ukrainian military. Testimony on those measures was largely opposed, with witnesses arguing Hawaii should prioritize local needs such as homelessness, infrastructure, and cost of living over additional aid to Ukraine; one support testimony was noted from the Democratic Party of Hawaii. Despite the opposition, both committees recommended passage with technical, nonsubstantive amendments, and the recommendations were adopted.
The committees also considered transportation-related resolutions. Senate Concurrent Resolution 182 and Senate Resolution 152 would initiate a summer streets pilot program, and Senate Concurrent Resolution 200 and Senate Resolution 180 would ask AMPO to coordinate a transportation management training program. Testimony on the summer streets proposal included support and opposition, with one witness saying community input should be gathered through existing district and community meetings rather than creating a pilot. The training-program measure drew opposition from a witness who argued it would add unnecessary bureaucracy. Both pairs were recommended for passage, with the summer streets resolutions passed unamended and the training-program resolutions passed with technical amendments.
In the Energy and Intergovernmental Affairs committee, Senate Concurrent Resolution 18 and Senate Resolution 14, concerning relocation of the Pearl City post office to Navy property, were recommended for passage with technical amendments. The committee also heard extensive testimony on Senate Concurrent Resolution 136 and Senate Resolution 150, which call for a geothermal energy working group. Supporters included the State Energy Office, PUC, consumer advocate, and others, though the energy office asked to move the report deadline to 2027. Opponents raised concerns about cost, health impacts, environmental risks, and Native Hawaiian representation. The chair proposed amendments to add a Native Hawaiian member, the consumer advocate, and the House and Senate energy committee chairs, clarify participation by utility, geothermal, and nonprofit representatives, and extend the report deadline to 2027. The resolutions were then recommended for passage with amendments, and all recommendations were adopted before adjournment.
