- We really look at where we're going to get the maximum nutrient reduction, that they're shovel-ready,
- most nutrient reduction, but also what's the greatest value.
- Yeah, so a nutrient-enhancing septic system has a requirement that it has a 65 percent reduction in nitrogen
Summary:
The Natural Resources and Disaster Subcommittee heard two informational presentations. First, the Department of Environmental Protection gave an overview of Florida’s water quality framework, explaining how numeric nutrient criteria, monitoring, TMDLs, and Basin Management Action Plans (BMAPs) are used to address impaired waters. DEP described recent changes intended to increase accountability, including five-year milestones in BMAPs, requirements for advanced wastewater treatment by 2033 in certain cases, limits on new conventional septic systems where sewer is available, enhanced nutrient-reducing septic requirements where sewer is not available, and a new agricultural regional water quality improvement element. The department also highlighted the Water Quality Improvement Grant Program, which has received nearly $1.4 billion over four years and funded more than 300 projects, as well as a public dashboard showing funded projects and a forthcoming trend-analysis dashboard for monitoring data.
Members asked about enforcement of BMAP milestones, septic-to-sewer coordination with local governments, PFAS and microplastics monitoring, septic system performance standards, wastewater facility compliance, and how many facilities remain below advanced wastewater treatment standards. DEP said it can enforce BMAP obligations through administrative orders, consent orders, court action, fines, and permit conditions, and that it inspects and verifies wastewater facilities while relying on reporting and site inspections for sewer infrastructure. The department also said nutrient-reducing septic systems must achieve a 65 percent reduction in nitrogen and phosphorus, with verification required when projects seek BMAP credit.
The committee then heard from the chief resilience officer on the Resilient Florida program, created in 2021 to address sea-level rise and coastal flooding. The presentation reviewed planning grants, vulnerability assessments, and the statewide critical-asset assessment, noting that all counties and most municipalities are expected to complete assessments by the end of 2026 and that vulnerability is now an eligibility requirement for future project funding. The program reported major statewide outcomes, including stormwater storage, miles of infrastructure and roadway protection, acres restored, and coastal protection projects, and highlighted examples such as breakwater improvements and lift-station elevation. Members asked about project delays, funding totals, overlap with other funding sources, and project prioritization; the program said delays often stem from design and permitting after award, that its reported totals reflect only grants it administers, and that projects are scored under the same criteria rather than being prioritized by asset type. The meeting ended with no further business and adjournment.

Summary:
The Committee on Environment and Natural Resources convened with a quorum present, heard opening remarks from Chair Rodriguez and member introductions, and discussed broad priorities including water quality, climate change, budget oversight, and accountability for environmental investments. Members emphasized concerns about nutrient pollution, springs, Lake Okeechobee, the Everglades, and the need for better data and measurable results.
The committee then received a presentation from DEP Deputy Secretary Adam Blaylock on the state’s water quality restoration framework. He explained how water quality standards, total maximum daily loads (TMDLs), Basin Management Action Plans (BMAPs), and reasonable assurance plans work together to address impaired waters, and noted that BMAPs are updated every five years with annual reviews in between. He also described recent statutory changes requiring five-year milestones, restrictions on new septic systems in certain areas, and public-facing data tools to track projects and water quality trends.
Members questioned whether BMAPs are producing enough improvement and whether the five-year update cycle is too slow. Blaylock said results can take years because of project lag and environmental variability, but that the department can adjust plans if data show they are not working. He also highlighted $2.9 billion in statewide water quality funding since 2019, nearly 1,100 funded projects, and a $1.1 billion water quality improvement grant program that now covers impaired waters beyond BMAP areas. The committee discussed agricultural projects, DEP and FDACS funding roles, and a new dashboard and centralized monitoring platform under development. No formal votes or other actions were taken, and the meeting ended with adjournment moved by the vice chair.

Summary:
The Joint Administrative Procedures Committee met on February 3, 2025, with a quorum present and took up three main items. First, the committee considered a large set of recommended objections to Agency for Health Care Administration rules, all centered on sunset provisions stating the rules would expire after five years. AHCA asked for another deferral while it reviewed the rules, arguing the sunset language was a form of self-restraint rather than an invalid exercise of rulemaking authority. Committee leadership disagreed that further delay would resolve the issue and moved to a single vote covering all objections. The motion passed by roll call, and the committee informed AHCA that an objection would be filed unless the agency amended the rules within 30 days.
The committee then heard an informational briefing from the Department of Environmental Protection on its Outstanding Florida Springs rule and stormwater rule. DEP explained that it did not prepare a statement of estimated regulatory cost for the springs rule because the proposed standards largely mirror existing water management district rules and the Central Florida Water Initiative framework, so DEP said there was no new regulatory burden. Members asked about permit authority, costs, and whether the rules were functionally different from prior rules. DEP maintained the rules set minimum standards and did not add costs beyond what regulated parties were already doing.
DEP also described implementation of the stormwater rule adopted under the 2020 Clean Waterways Act and later ratified by the Legislature in 2024. DEP said the rule was the product of years of workshops and technical advisory committee meetings, and that the final version included lower-cost alternatives, grandfathering, and phased implementation. DEP estimated the rule’s cost at about $2,600 per acre in the revised CERC, while industry witnesses said the real cost could be much higher, especially if land costs are included. A home builders representative argued the estimate understated impacts, while a stormwater engineer said the rule gives more flexible, performance-based tools and could become more cost-effective over time.
Finally, Senator Graal presented proposed Chapter 120 changes in SB 108, aimed at tightening and modernizing rulemaking. The proposal would require five-year rule reviews, annual agency reporting, faster notice of proposed rulemaking after authorizing legislation, electronic filing, public access to incorporated materials, clearer tracking of technical changes, and limits on how long rules can remain pending ratification. Members discussed whether the Legislature should be more specific in statutes about rulemaking deadlines and whether agencies should be more accountable when rules stall. No formal action was taken on the Chapter 120 proposals, and the committee adjourned after discussion.

Summary:
The committee on Energy and Environmental Protection heard testimony on three measures related to cleaner fuels. On HB 1986, which would require the Department of Transportation to adopt rules for a clean fuel standard by January 1, 2028 and include reporting and public informational sessions, testimony was largely supportive from state commissions, fuel companies, airlines, and other industry and advocacy groups. Supporters said the bill would create a long-term framework for reducing emissions and developing cleaner fuels in Hawaii. Opposition came from Energy Justice Network, which argued that so-called clean fuels are not carbon-free, would be costly, and could delay a needed transition to electrification. The department later said it was monitoring the bill and was concerned about costs. No vote or final action was taken in the hearing.
The committee then heard HB 1694, a sustainable aviation fuel tax credit bill that would provide a per-gallon credit for SAF, cap annual credits at $20 million, require reporting, and sunset in 2035. The Department of Taxation testified on administration, while the Department of Transportation said it supported the measure as a short-term strategy to jump-start SAF until the clean fuel standard ramps up. Airlines, fuel companies, the Hawaii Food Industry Association, the Hawaii Renewable Fuels Coalition, and others supported the bill, saying it would send a market signal, help close the cost gap with conventional jet fuel, and encourage local production and investment. Opponents, including Energy Justice Network, Life of the Land, and Ted Metros, argued the bill would be expensive, could lock in a transitional fuel system, and would not produce enough fuel to meet demand. Committee members asked about the likely impact and the share of total fuel demand the credit could support; DOT said the supported gallons would be only a very small percentage of annual demand and that the credit was intended to work alongside the future clean fuel standard.
Finally, the committee took up HB 1695 HD1 on renewable fuel, which expands the renewable fuels production tax credit. Testimony was again mixed but generally supportive from the Department of Transportation, Department of Taxation, Island Energy Services, airlines, the Tax Foundation, Pana Pacific, and the Hawaii Farm Bureau. Supporters said the measure would encourage local feedstock production, create agricultural opportunities, and help attract investment in renewable fuels. Pana Pacific requested an amendment to explicitly include camelina in the definition of renewable feedstocks. Opponents, including Energy Justice Network and Life of the Land, repeated concerns about cost, imported feedstocks, and the risk of undermining full electrification goals. The hearing transcript does not show any vote or final committee action on HB 1694 or HB 1695 HD1.

Summary:
The House Committee on Natural Resources, Energy and Water heard three bills related to the Water Infrastructure Finance Authority (WIFA) and county wastewater issues. HB 2029 would require applicants for water conservation grant funds to provide additional information about the long-term water savings, efficiency, reliability, and intended use of grant money. WIFA testified neutral, saying most of the information is already collected under agency policy and the bill would mainly codify existing practice. The committee passed HB 2029 on a 9-1 vote.
HB 2030 would remove education and research programs from the list of allowable uses for the water conservation grant fund. Supporters of the bill argued the fund should prioritize projects that put more water savings “on the ground,” while opponents said education and research can support conservation and help identify effective projects. WIFA said about 15 of 211 funded projects had some education or research component, totaling about $10.5 million and an estimated 180,000 acre-feet in savings. The committee passed HB 2030 on a 6-4 vote, with several members opposing the bill because they saw value in those projects.
HB 2096 would expand WIFA funding to allow counties to receive assistance for remediating, closing, or replacing cesspools that threaten groundwater, surface water, or public health, and would let counties offer income-based assistance and report annually on the program. County and association witnesses described cesspools as an ongoing rural public health problem, especially in Gila County, and said the bill would help homeowners afford required upgrades. WIFA and ADEQ were neutral, noting the bill would clarify county authority and use existing federal revolving fund dollars; testimony also explained that current law already requires cesspools to be upgraded when discovered or when a property is remodeled. The committee passed HB 2096 unanimously, 10-0, and then adjourned.

Summary:
The Assembly Select Committee on Biotechnology and Medical Technology held an informational hearing on the role of biotechnology industries in wastewater treatment, hosted at Bakar Labs on the UC Berkeley campus. Opening remarks emphasized California’s water scarcity, the rising cost of wastewater infrastructure, and the need to reuse and clean contaminated water. Committee members framed the hearing as a look at both current treatment challenges and emerging technologies that could improve water quality, affordability, and resilience over time.
The first panel focused on statewide wastewater challenges. BACWA Executive Director Laurie Fono described wastewater plants as part of a broader circular economy, noting their roles in recycled water, environmental enhancement, biosolids management, carbon sequestration, and renewable energy generation. She highlighted major challenges including aging 1970s-era infrastructure, nutrient reduction mandates, sea level rise, evolving regulations, and PFAS source control. She said Bay Area agencies face about $11 billion in nutrient reduction costs, with rate increases, state revolving funds, WIFIA loans, and bonds as the main financing tools. Members asked about regional differences, energy revenue opportunities, smaller decentralized plants, and agricultural collaboration.
The second panel featured researchers and lab experts discussing biotechnology solutions. Lawrence Berkeley National Lab’s Dr. Romine Chakarvati described using microbial communities and machine learning to help break down PFAS and treat produced water. CEL Analytical’s Dr. Yigi Dearborn explained pathogen testing for direct potable reuse, wastewater monitoring, and the need for larger sample volumes and more funding to validate methods for viruses and protozoa. Stanford’s Dr. Chunhung-Shin presented an anaerobic membrane system that turns domestic wastewater into clean water and energy with less biosolids and lower operating costs. Committee members asked about AI, assay development, scaling technologies, and funding priorities. Public comment from the California Association of Sanitation Agencies stressed the need to balance scalability, reliability, and affordability, and the hearing adjourned without any formal vote or action.

Summary:
The meeting focused on the use of biosolids on farm and ranch land, with testimony from Oklahoma State University experts, a conservation official, and an engineering representative about the benefits, risks, and regulatory implications. Dr. Lusk described OSU’s long history of soil fertility research and said biosolids can provide nutrients and organic matter, but also may carry contaminants such as PFAS, heavy metals, pharmaceuticals, microplastics, and pathogens. He emphasized that many questions remain unanswered, especially about contaminant uptake into soil, crops, livestock, and humans, and said existing EPA and Oklahoma DEQ regulations address some treatment and application standards but may not fully cover PFAS. Dr. Arnell expanded on nutrient management, explaining that biosolids can function similarly to manure as a fertilizer source, especially for nitrogen and phosphorus, but should be tested, incorporated into soil, and applied under permit conditions to reduce runoff and other losses. He said PFAS testing methods are not yet standardized and that more research is needed to determine sampling protocols, movement in soil, and long-term effects.
Committee members asked whether farmers and ranchers should be notified of risks, whether PFAS is currently tested, how many counties use biosolids, and what research would be needed for a dissertation-level study. The witnesses generally agreed that landowners should be informed of known risks and uncertainties, but said the science is still developing. Dr. Arnell said a unified testing method is needed before reliable PFAS monitoring can be done, and suggested that a multi-year study would be required to understand soil movement, crop uptake, and livestock impacts. Greg Scott of the Oklahoma Conservation Commission framed the issue as a waste-management problem, noting that human waste streams contain contaminants and that soil type affects how pollutants move; he said sandy soils pose greater movement risks than clay soils and that current best practice is incorporation, careful timing, and avoiding steep or sensitive sites. He also said PFAS are widespread and not naturally occurring in the way some other compounds are, and that liability and cleanup costs are major concerns.
Mary Elizabeth Mock of Garver Engineering focused on the practical and financial consequences of a possible moratorium on land application, saying most of Oklahoma’s biosolids are currently land applied and would otherwise have to go to landfills. She warned that many landfills are nearing capacity, tipping fees could rise sharply, and cities such as Tulsa and Norman could face large increases in disposal costs, which would ultimately be borne by ratepayers and taxpayers. She also said septic system maintenance costs could rise if land application options shrink, potentially leading to deferred maintenance and system failures. Mock urged a tiered, data-driven approach to PFAS regulation and said advanced treatment technologies may help in the future, but they are still emerging and expensive. No votes were taken; the session consisted of presentations and member questions.
