Read the full official summary
Existing law requires the Department of Resources Recycling and Recovery to adopt and revise regulations setting forth minimum standards for composting, in accordance with law. Existing regulations require all compostable materials handling activities to obtain a permit prior to commencing operations and to comply with specified requirements. Existing regulations specify 4 regulatory tiers for composting operations, with different requirements for each tier. The 4 tiers are excluded, enforcement agency notification, registration permit, and full solid waste facility permit.
In the excluded tier, existing regulations specify the "excluded activities" that do not constitute compostable material handing operations or facilities and, therefore, are not subject to permit requirements or other regulatory requirements. One of the excluded activities is the composting of green material, agricultural material, food material, and vegetative food material, alone or in combination, 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 expand this excluded activity exemption for composting activities by eliminating the maximum square-foot condition and authorizing a total amount of feedstock and compost onsite at any one time of up to 200 cubic yards, or 500 cubic yards for a composting activity owned by a public agency, as defined. The bill would also authorize the Department of Resources Recycling and Recovery to further increase those amounts by regulation. The bill would also make the composting of agricultural materials and residues that are from a large-scale biomass management event at an agricultural facility that does not otherwise operate as a solid waste facility an excluded activity, as specified.
Existing regulations prohibit a composting operation from giving away or selling more than 1,000 cubic yards of compost product annually if it is in the excluded tier or if it is an agricultural material composting operation in the enforcement agency notification tier, its feedstock is both green material and agricultural material, and the operation is located on land zoned for agricultural uses.
This bill would authorize composting activities to give away or sell up to 5,000 cubic yards of compost product annually. The bill would authorize the Department of Resources Recycling and Recovery to increase, by regulation, that amount when the composting is of agricultural materials and residues that are from a large-scale biomass management event at an agricultural facility.
