Climate change: short-lived climate pollutants: organic waste reduction.

Existing law establishes methane emissions reduction goals that include a target to reduce landfill disposal of organics by 75% of the 2014 level of the statewide disposal of organic waste by 2025. Existing law requires the Department of Resources Recycling and Recovery, in consultation with the State Air Resources Board, to adopt regulations to achieve the organic waste reduction goals. Existing law authorizes a local jurisdiction to count specified recovered organic waste products towards up to 10% of its recovered organic waste procurement target. This bill would additionally authorize a local jurisdiction to count a beneficial agricultural amendment derived from organic waste that may include biosolids towards up to that 10% of its recovered organic waste procurement target if the material meets the requirements to be deemed to constitute a reduction in landfill disposal, the material is registered or approved for end use as a fertilizing material by the Department of Food and Agriculture, and the material is not derived from, or processed using, specified activities relating to the final deposition or management of solid waste, as provided. The bill would require the amount of the procured materials to be calculated using the dry weight of the materials. Existing law authorizes a local jurisdiction to count compost produced and procured from specified compost operations towards its recovered organic waste procurement target, including, under specified conditions, operations composting green material, agricultural material, food material, and vegetative food material if the total amount of feedstock and compost onsite at any one time does not exceed 100 cubic yards and 750 square feet. This bill would repeal that authorization, but would instead authorize a local jurisdiction to count towards its procurement target compost produced and procured from certain composting operations, including the composting of green material, agricultural material, food material, and vegetative food material if the total amount of feedstock and compost onsite at any one time does not exceed either 200 cubic yards or, for a composting activity owned by a public agency, as defined, 500 cubic yards, amounts that may be increased by regulation, as specified.
