AB 2776 California Assembly · 2025-2026 Regular Session

Hazardous materials.

Summary
(1) The hazardous waste control laws require the Department of Toxic Substances Control to regulate the handling and management of hazardous waste and hazardous materials. A violation of the hazardous waste control laws is a crime. Existing law prohibits an owner or operator of a storage facility, treatment facility, transfer facility, resource recovery facility, or disposal site from accepting, treating, storing, or disposing of a hazardous waste at the facility, area, or site, unless the owner or operator holds a hazardous waste facilities permit, as provided. Existing law provides that a facility with the onsite accumulation of hazardous waste for a specified period of time by a generator of less than 1,000 kilograms of hazardous waste in any calendar month is not a storage facility if the quantity of hazardous waste accumulated onsite never exceeds 6,000 kilograms, the generator is in compliance with certain federal regulations, and the generator does not hold acutely or extreme hazardous waste in an amount greater than one kilogram for a specified period of time. Existing state regulations authorize a small quantity generator to accumulate various quantities of hazardous waste without a permit if certain conditions are met. This bill would instead provide that a facility with the onsite accumulation of hazardous waste for a specified period of time by a generator of less than 1,000 kilograms of hazardous waste in any calendar month is not a storage facility if the generator complies with those state regulations. Existing law imposes various manifest requirements for transporting hazardous waste, including, among others, requiring any person generating hazardous waste that is transported, or submitted for transportation, for offsite handling, treatment, storage, disposal, or any combination thereof, to complete a manifest. Existing law authorizes specified manifest requirements for transporting hazardous waste to be satisfied through the use of the United States Environmental Protection Agency electronic manifest (e-Manifest) system. This bill would require certain reports required to be submitted to the department when a manifest is not received to instead be submitted to the e-Manifest system. For purposes of the hazardous waste control laws, "treatment" means any method, technique, or process that is not otherwise excluded from the definition pursuant to these laws and that is designed to change the physical, chemical, or biological character or composition of any hazardous waste or any material contained therein, or that removes or reduces its harmful properties or characteristics for any purpose. Existing law excludes from that definition of "treatment" specified activities. This bill would exclude from that definition of "treatment" the compaction of hazardous waste under specified conditions, including, among others, requiring that the waste being compacted is not a free liquid, as defined, is not a solid that meets the ignitability or reactivity characteristic, as described, does not alter the physical, chemical, or biological character or composition of the waste, other than physical changes inherent to compaction, and does not result in fugitive dust, fire, or explosion. Existing law designates certain generators of hazardous waste as a very small quantity generator if they generate less than certain amounts, based on type, of hazardous waste per calendar month established in a specified federal regulation. This bill would delete the reference to that federal regulation and instead designate as very small quantity generators those that generate less than certain amounts established in a state regulation with identical thresholds as the federal regulation for the generation of acute and nonacute hazardous waste, except as provided. This bill would also make other changes related to hazardous waste and nonsubstantive changes. To the extent this bill changes the conduct that constitutes the crime of violating the hazardous waste control laws, the bill would impose a state-mandated local program. (2) Existing law establishes the Board of Environmental Safety in the Department of Toxic Substances Control with specified duties. Existing law requires the board to annually prepare and transmit to the Secretary for Environmental Protection an annual review of the department's performance as compared to its objectives, including, but not limited to, the performance of the Director of Toxic Substances Control. This bill would require the board to post that review on its internet website. The bill would authorize the review to include, to the extent feasible using existing resources, other reviews, recommendations, and findings related to the department's performance, as specified. (3) The Aboveground Petroleum Storage Act (the act) generally regulates aboveground storage tanks that contain petroleum and that meet certain requirements. The act requires its provisions to be implemented by a unified program agency, as provided, and requires the Office of the State Fire Marshal to adopt regulations implementing these provisions. A knowing violation of specified provisions of the act after reasonable notice of the violation is a crime. The act specifically excludes from the definition of an "aboveground storage tank" for purposes of the act oil-filled electrical equipment if the oil-filled electrical equipment meets specified conditions. The act further excludes from that definition a tank in an underground area that has the capacity to store less than 55 gallons of petroleum, has secondary containment, and is inspected monthly, if a specified condition is met. For purposes of the act, a "tank in an underground area" means a stationary storage tank that meets specified criteria and, among other things, the structure in which the storage tank is located, at a minimum, provides for secondary containment, as provided. For purposes of this definition, a shop-fabricated double-walled storage tank with a mechanical or electronic device used to detect leaks in the interstitial space meets the requirement for secondary containment of the contents of the tank. This bill would revise the exemption for oil-filled electrical equipment by clarifying that it applies if the single piece of equipment meets those conditions. The bill would revise the exemption for a tank in an underground area that has the capacity to store less than 55 gallons of petroleum by requiring the tank to have secondary containment of the contents of the tank, associated piping, and ancillary equipment, until cleanup occurs, and if the tank, piping, and ancillary equipment are inspected monthly. To the extent that the revisions to these exemptions would impose a higher level of service on local agencies, the bill would impose a state-mandated local program. The act further requires each owner or operator of a tank facility to immediately, upon discovery, notify the Office of Emergency Services and the unified program agency of the occurrence of a spill or other release of petroleum, as specified, that is required to be reported pursuant to specified water control laws imposing water discharge notice requirements. Existing water control laws exempt a discharge in compliance with waste discharge requirements or other water control laws from that notification requirement. This bill would instead make that notification requirement applicable to a discharge of any petroleum into or upon any waters of the state. The bill would make the exemption pursuant to the water control laws applicable to that notification requirement. By expanding the scope of a crime, the bill would impose a state-mandated local program. This bill would also make clarifying changes to the act. (4) Existing law provides for the regulation of underground storage tanks by the State Water Resources Control Board and the unified program agency. Existing law defines an "underground storage tank" for these purposes. Existing law requires the interstitial space of the underground storage tank to be maintained under constant vacuum or pressure such that a breach in the primary or secondary containment is detected before the liquid or vapor phase of the hazardous substance stored in the underground storage tank is released into the environment. This bill would make that requirement applicable to the interstitial space of the underground storage tank that is buried. Existing law requires a local agency to inspect every underground tank system within its jurisdiction at least once every year. Existing law requires a local agency to prepare a compliance report detailing the inspection and to send a copy of this report to the permitholder and the owner or operator, if the owner or operator is not the permitholder. Existing law requires, within 60 days after receiving a compliance report or special inspection report, the permitholder to file with the local agency a plan to implement all recommendations contained in the compliance report or to demonstrate, to the satisfaction of the local agency, why these recommendations should not be implemented. This bill would instead require the permitholder to return to compliance within 30 days after receiving a compliance report or special inspection report and would eliminate the option to file a plan to implement all recommendations. The bill would authorize the local agency to approve a plan to return to compliance in excess of 30 days, as long as the plan to return to compliance is received by the local agency within 30 calendar days of the permitholder receiving the compliance report or special inspection report. (5) Existing law requires a business to establish and implement a business plan for emergency response to a release or threatened release of a hazardous material in accordance with prescribed standards if the business meets specified conditions at any unified program facility, including, among other conditions, if the business handles a hazardous material or a mixture containing a hazardous material that has a quantity at any one time during the reporting year that is equal to, or greater than, 55 gallons for materials that are liquids, 500 pounds for solids, or 200 cubic feet for compressed gas. This bill would provide that the above provision does not apply to specified gasses, including oxygen, nitrogen, or nitrous oxide, as provided. (6) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for specified reasons.

MODERATE
The August 18 Senate amendment to AB 2776 substantially revised the conditions under which compaction of hazardous waste is excluded from the definition of 'treatment.' The key changes narrow the liquid prohibition from 'not a liquid' to 'not a free liquid,' add new prohibitions for solids that produce or contain free liquids when compacted, separate the ignitability and reactivity checks into their own condition, and clarify that physical changes inherent to compaction (volume reduction, density increase, shape change) are acceptable. These changes make it easier for generators to compact certain hazardous wastes without triggering treatment permit requirements.
DEFINITION

The liquid prohibition in the compaction exclusion changed from 'not a liquid' to 'not a free liquid,' using the SW-846 Method 9095B Paint Filter Liquids Test definition. This narrows what is prohibited, potentially allowing compaction of some materials that would have been excluded under the broader 'liquid' standard.

The condition about altering waste character was revised to clarify that physical changes inherent to compaction (reduction in volume, increase in density, changes in shape or form) are acceptable, and the prohibition now specifically targets changes beyond those inherent to compaction. This provides more certainty to generators about what level of physical change is permissible.

REQUIREMENT

Two new conditions were added: (ii) the waste must not be a solid or semisolid that produces a free liquid when compacted, and (iii) the waste must not be a solid that contains a free liquid. These close potential gaps where compacting certain solids could release liquids.

The ignitability and reactivity characteristic checks were separated from the liquid prohibition into their own standalone condition (iv), making the regulatory structure clearer. The reactivity reference in one instance changed from Section 66261.23 to Section 66260.10 of Title 22 of the California Code of Regulations.

TECHNICAL

The overall structure of the compaction exclusion was reorganized from a nested subclause format (i)/(I), (ii)/(II), (iii)/(III) to a flatter numbered list (i) through (vi), and the framing changed from 'if all of the following conditions apply' to 'if none of the following conditions apply,' inverting the logic from positive requirements to negative prohibitions.

Section 25125.7 (board annual performance review) had minor language changes: 'Recommendations for legislative, regulatory, and budgetary changes needed' was simplified to 'Legislative, regulatory, and budgetary changes,' removing the word 'recommendations' and making the board's authority more direct.
