LEGISLATIVE COUNSEL'S DIGEST
AB 411, Papan. Livestock carcasses: disposal: composting.
Existing law prohibits a dead animal hauler or any other person from transporting a dead animal to any place, other than to certain specified facilities or destinations, unless a certain waiver is granted by the State Veterinarian, as specified.
Existing law requires the Department of Resources Recycling and Recovery to adopt and revise minimum standards for solid waste handling, transfer, composting, transformation, and disposal, as prescribed. Pursuant to this authority, the department has adopted a regulation that prohibits the composting of unprocessed mammalian tissue except when received from certain sources.
This bill would, notwithstanding those prohibitions, authorize any part of a livestock carcass resulting from a routine livestock mortality event or on-farm processing to be composted if certain requirements are met, including, among others, that the composting is conducted in accordance with best management practices for livestock composting adopted by the Secretary of Food and Agriculture, as specified.
