CA SB1234

Establishes comprehensive state regulation of metal shredding facilities through new Chapter 6.4, replacing previous alternative management standards for metal shredder waste.

Requires metal shredding facilities to obtain permits from the Department of Toxic Substances Control (DTSC) or be deemed to have permits if operating in compliance; existing facilities automatically deemed permitted if operating on effective date.

Classifies scrap metal, metal shredder aggregate, and chemically treated metal shredder residue (CTMSR) as non-hazardous waste when managed according to specified standards, including chemical treatment with silicate solution and cement.

Imposes operational requirements including inbound source control policies to prevent shredding of hazardous materials, fire prevention plans, stormwater management, structural enclosures for storage, and annual reporting to DTSC.

Authorizes DTSC to collect annual fees from metal shredding facilities for implementation and administration, with fees deposited into a separate Hazardous Waste Control Account subaccount and exempts facilities from certain Chapter 6.5 hazardous waste fees.
