SB 811 gives the Department of Toxic Substances Control (DTSC) explicit authority to permit and regulate metal shredding facilities in California, defines new material classes (including “chemically treated metal shredder residue” or CTMSR), and replaces earlier, patchwork policies. The bill requires comprehensive permit applications, annual public reporting, site‑specific conditions, and allows existing facilities to operate only while implementing department‑approved interim plans.
The bill matters because it rewrites how shredded metal byproducts are treated and transported: it creates a narrow path for metal shredder aggregate and treated residue to avoid classification as hazardous waste if facilities meet technical, operational, and recordkeeping standards. That conditional non‑waste status, plus prescriptive fire, pile, and transport controls, will change operations, compliance costs, and liability allocation for shredders, haulers, and receiving landfills.
At a Glance
What It Does
SB 811 requires DTSC permits for most metal shredders, mandates application elements (fire plans, housekeeping, inventory controls, financial assurance, offsite transfer plans), and authorizes department regulations and interim controls. It establishes CTMSR treatment standards and limits where treated residue may be disposed.
Who It Affects
Existing and new metal shredding facilities (with a defined small‑facility carve‑out), transporters of metal shredder aggregate and CTMSR, landfills that accept treated residue, local fire departments and air districts, and DTSC as the permitting authority.
Why It Matters
The bill replaces prior informal guidance with a statutory permitting regime that ties non‑waste status to specific management and a documented treatment recipe, shifting legal certainty and compliance burdens onto operators and transporters while increasing public transparency and agency oversight.

What This Bill Actually Does
The bill creates a self‑contained regulatory chapter for metal shredding facilities and a new material category—chemically treated metal shredder residue (CTMSR). It opens by defining covered terms and carving out certain operations (like feeder yards, tire or wood shredders, and pure nonmetal shredders).
DTSC gains express authority to write implementing regulations and to apply technical requirements of existing hazardous waste regulations to in‑process materials without labeling those materials as waste when managed under the chapter.
DTSC must issue permits for covered facilities. Permit applications must include detailed operational plans: fire prevention and response, housekeeping, inventory controls that enforce pile size and duration limits, security, contingency and preparedness plans, a closure plan, financial assurance for closure and third‑party liability, and a plan describing any offsite transfers of metal shredder aggregate.
The department will post application materials online, conduct at least one site visit, evaluate community emission reduction and health risk assessments, and solicit public comment via pre‑application and permit hearings. Applications are to be decided within three years of completion, and permits are fixed‑term (generally 10 years) with renewal procedures.For facilities that cannot immediately meet every new requirement, the bill lets them operate temporarily if they disclose noncompliant provisions and implement a department‑approved compliance plan and schedule.
Interim obligations include immediate fire controls, adherence to pile limits, financial assurance initiation, and starting a preliminary endangerment assessment. DTSC can impose interim measures necessary to protect health and the environment while a permit is pending.Operationally the bill is prescriptive.
It bans shredding of specified hazardous or special‑handling items unless properly depolluted, requires inbound load checking and five‑year retention of load records, mandates employee training, and imposes concrete or equivalent surfacing, enclosures for aggregate handling, weekly inspections, and continuous surveillance of piles. Pile management rules set explicit processing time windows and require continuous temperature monitoring (e.g., infrared alarms) and on‑site staffing.
Transport rules force tarping/containment, defined bill‑of‑lading elements, three‑year record retention, and transporter liability insurance; transporters become the generator if a release occurs during shipment. Finally, the bill prescribes a treatment recipe and handling rules for CTMSR, restricts disposal to approved landfill units or sites with appropriate water‑board oversight, and requires annual CTMSR shipment reporting to DTSC.
The Five Things You Need to Know
CTMSR qualifies as non‑hazardous only if the residue is treated with at least 0.7 gallons of silicate solution per short ton plus cement equal to 8.5% of the untreated residue’s weight (unless an alternate recipe is approved).
Feedstock and aggregate pile limits: no individual feedstock pile may exceed the amount processable in 24 hours; no individual metal shredder aggregate pile may exceed the amount processable in 48 hours, and piles may not remain inactive for more than 48 hours except under limited, approved circumstances.
A small metal shredding facility is carved out as one that processes ≤250 tons per day or ≤65,000 tons per year and meets three conditions (no whole vehicles/white goods/ag equipment shredding, no on‑site chemical CTMSR treatment, and no use of on‑site thermal oxidizers).
DTSC must act on a completed permit application within three years (with allowances for CEQA or extensions); facilities that have timely, complete applications and meet interim requirements may continue operating while DTSC reviews the permit.
CTMSR shipments require a shipping manifest with quantity, generator and destination contact details and dates; the generating facility must submit an annual CTMSR report by Feb 1 listing destination landfills and tonnages for the prior calendar year.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definitions, scope, and rulemaking authority
This block defines the chapter’s technical vocabulary (CTMSR, metal shredder aggregate, feedstock, small facility, etc.), narrows covered facilities and lists explicit exclusions such as feeder yards and pure nonferrous processors, and repeals prior DTSC policy (Official Policy 88‑6). It also preserves the department’s ability to adopt implementing regulations and to apply specific technical requirements from existing hazardous waste regulations to in‑process materials while maintaining the chapter’s limited non‑waste classifications.
Permit requirements, contents, and public process
DTSC permits are required for most shredders; applications must supply detailed operational and emergency plans, inventory and housekeeping plans, financial assurance evidence, offsite transfer descriptions, and training programs. DTSC must post application materials publicly, do a site visit, factor in community emission reduction plans and health risk assessments, provide extended public comment periods (minimum 45 days) and respond to comments, and coordinate CEQA review. Permits incorporate conditions from other agencies and may include facility‑specific obligations to address local risks.
Interim compliance for existing facilities
Operators who cannot immediately comply can continue operating only after identifying noncompliant provisions, submitting department‑approved compliance plans and schedules, initiating financial assurance, beginning a preliminary endangerment assessment, and meeting immediate fire and pile limits. DTSC can issue interim measures and will require facilities to implement them on a defined schedule; failure to comply triggers enforcement under the chapter’s enforcement provisions.
Operational controls: inbound checks, fire prevention, housekeeping, and pile management
Operators must implement inbound source control to prevent hazardous items from entering the shredder, keep written load‑checking records for five years, and have depollution procedures for fuels and oils. The bill demands concrete surfacing or equivalent, enclosed conveyance where feasible, weekly inspections, continuous pile surveillance, infrared or equivalent temperature monitoring, and a fire plan coordinated with local responders. Inventory management rules set throughput‑based pile size limits and strict maximum durations for stockpiled feedstock and aggregate, with specific additional controls during extended breakdowns.
Facility changes, transport, and reporting
Many physical or operational upgrades (e.g., efficiency gains, equipment changes, paving, abatement systems) can be implemented without prior DTSC approval if DTSC receives notice within 30 days and the facility remains substantially compliant; DTSC can require modifications if impacts appear significant. Transport rules require tarping/containment, direct shipment, detailed bills of lading, transporter liability insurance, and three‑year retention of shipping records. Annual reporting to DTSC must summarize offsite shipments and operational changes.
Material classification and CTMSR treatment/disposal rules
The statute creates conditional non‑waste status for scrap metal, in‑process metal shredder aggregate, intermediate products, and CTMSR if managed under approved plans. For residues that are non‑RCRA hazardous, the bill sets a prescriptive stabilization recipe (silicate plus cement), tight accumulation‑area construction and labeling standards, and limits disposal to composite‑lined municipal landfill units or sites authorized under Water Code waste discharge permits. Transporters and generators have explicit duties during shipment, and unauthorized releases during transport shift generator obligations to the transporter.
Interagency coordination, enforcement hooks, and public transparency
The chapter preserves local air district, unified program agency, and local health department authorities, requires coordination with local fire and emergency responders, and mandates public posting of applications and permit status. While it references enforcement (Article 8) rather than laying out penalties here, DTSC can impose interim controls, require additional permit conditions based on site specifics and community risks, and deny or condition permits based on compliance history and health‑risk evidence.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Nearby communities and sensitive receptors — the bill requires fire prevention plans, temperature monitoring, pile limits, and public engagement, reducing acute fire and fugitive‑dust risks and increasing transparency about facility operations.
- DTSC and local regulators — the statute centralizes permitting authority, prescribes application content, and clarifies where technical hazardous‑waste rules apply, giving agencies clearer enforcement and oversight tools.
- Recyclers and downstream buyers who meet the rules — facilities that comply and treat residue per the recipe can have CTMSR excluded from hazardous‑waste labeling, facilitating transport and disposal to authorized landfills and preserving marketability of recovered metals.
- Local fire departments and first responders — mandated coordination, shared plans, and required on‑site water/suppression access improve response readiness and reduce uncertain tactical conditions at shredder fires.
Who Bears the Cost
- Metal shredding facility owners/operators — significant capital and operating costs for enclosures, paving, continuous monitoring (infrared systems), staffing, documentation, financial assurance, and possible changes to throughput or layout to meet pile limits and treatment requirements.
- Transporters and haulers — must maintain containment, follow strict manifesting, secure specified liability insurance, and assume generator‑level responsibilities if releases occur in transit, increasing insurance and operational burdens.
- Receiving landfills and reuse sites — must accept CTMSR only if authorized and constructed appropriately (composite‑lined units or under water‑board WDRs), potentially requiring new approvals or operational segregation and increasing incoming waste characterization responsibilities.
- Small facilities and feeder yards that are newly captured — while some small facilities get extra time, others near the processing thresholds may still need to invest in monitoring, inspection regimes, or to restructure operations to remain exempt.
Key Issues
The Core Tension
SB 811 pits the need for clear, enforceable public‑health and environmental protections (fire controls, pile limits, a treatment recipe, and public transparency) against the metal recycling industry's need for operational flexibility and predictable regulatory burdens; the statute solves some legal uncertainties but creates operational and enforcement challenges that will require DTSC judgment calls and potential tradeoffs between strict prescriptive standards and performance‑based flexibility.
The bill ties non‑waste status for CTMSR to a narrow, prescriptive treatment recipe and containment conditions. That approach creates regulatory predictability but risks either over‑ or under‑treatment because shredder residues vary widely in chemical composition; DTSC’s ability to approve alternative recipes will be critical but may introduce case‑by‑case uncertainty.
The transporter‑as‑generator rule for releases during shipment clarifies liability but shifts immediate cleanup and regulatory obligations onto carriers, which could raise transport costs and contractual disputes between shredders, haulers, and landfills.
Implementation capacity is another practical tension. DTSC must review detailed applications, post materials publicly, coordinate CEQA and local agencies, and adjudicate permit conditions within statutory timeframes; the three‑year review window plus CEQA extensions could bottleneck approvals and leave facilities operating under interim controls for extended periods.
The law also increases the information that becomes public (application materials, shipping logs), raising confidentiality and trade‑secret issues that DTSC will need to manage under public‑records law while preserving community right‑to‑know. Finally, operational rules like 24–48 hour pile processing limits improve safety but may be hard to meet during supply surges, equipment downtime, or seasonal constraints, forcing facilities to choose between costly redundancy investments or constrained throughput.
