House Bill 1154 strengthens environmental and public health protections by modifying the permitting process for solid waste handling facilities. It requires the state Department of Ecology to review and approve permits for new or modified landfill facilities *before* local health departments can issue or renew them, a change effective August 1, 2027. For other solid waste handling facilities, the state Department will continue to review permits after local issuance and retains the ability to appeal. Additionally, the bill involves the Department of Agriculture in reviewing composting facilities that receive materials from quarantined areas to prevent the spread of diseases or pests.

HB 1912 establishes a system for tracking and reporting sales of fuel used for agricultural purposes, which are exempt from the state's Climate Commitment Act. Fuel sellers, including retail stations and suppliers, can register with the Department of Ecology to track and report these exempt sales. Registered sellers must make exempt fuel available at a differential rate or credit purchasers to reflect the absence of associated compliance costs under the climate act. This ensures the agricultural exemption is properly applied and monitored, affecting fuel sellers, suppliers, and agricultural users starting January 1, 2026.

HB 1514, titled "Encouraging the deployment of low carbon thermal energy networks," amends state law to explicitly allow existing electrical and gas companies to own, operate, or manage thermal energy networks within Washington state. The bill expands the definitions of "electrical company" and "gas company" in RCW 80.04.010 to include this authority. This change aims to encourage the deployment of low-carbon heating and cooling infrastructure by enabling utility companies to develop and provide these services. This legislation became Chapter 263, 2025 Laws, and will be effective on July 27, 2025.

Senate Bill 5175 establishes a photovoltaic module stewardship and takeback program in Washington state. It requires manufacturers of photovoltaic modules to finance and implement a system for the convenient, safe, and environmentally sound recycling of these modules. Manufacturers, individually or through a stewardship organization, must submit a plan to the Department of Ecology detailing how they will cover the costs of collection, management, and recycling, ensuring no charge to the last owner. The program aims to minimize hazardous substances and maximize the recovery of valuable materials, including rare earth elements, from used solar panels.
