Full Breakdown
040(H) of the Solid Waste and Edible Food Recovery chapter lets any generator use on-site composting, community composting, or another composting operation for organic material instead of the curbside organics cart, but only if the operation conforms to applicable land use, permitting and health rules, including CalRecycle's composting facility regulations. 040(G) allows feeding organic material to animals kept on the premises, provided the premises stays sanitary to the city manager's satisfaction and any animal-keeping rules elsewhere in the code are followed. 010 caps what counts as 'community composting' at a total of one hundred cubic yards of feedstock and finished compost, and no more than seven hundred fifty square feet of area, on-site at any one time; a bigger operation moves outside that definition and into full solid waste facility regulation. 130, so the agencies can plan for organics processing capacity across the county.
Violations & Fines
Composting that exceeds the community composting size limits in Section 8.12.010, or that is not sanitary or otherwise fails to conform to CalRecycle and land use rules under Section 8.12.040(H), loses its exemption from the curbside organics requirement and is treated as noncompliance with Chapter 8.12, subject to the chapter's infraction and administrative fine schedule under Section 8.12.170, up to $500 for repeat violations.
