Pomona, CA Landscaping Rules: Composting (2026)

City Code Sec. 62-581 defines "community composting" as any activity that composts green material, agricultural material, food material and vegetative food material, alone or combined, so long as the total feedstock and compost on site at any one time does not exceed 100 cubic yards and 750 square feet, tracking the state cap in 14 CCR Sec. 17855(a)(4). Below that ceiling, an operation counts as community composting rather than a regulated solid waste management facility; above it, Sec. 62-842 requires the operator to obtain the city's land-use, environmental and other approvals as a full composting facility.

Individual generators are expressly free to choose this route: Sec. 62-653(a) tells single-family organic waste generators they may manage their organic waste by preventing or reducing it, managing it on site, or using a community composting site under 14 CCR Sec. 9(c), instead of subscribing to every tier of the city's organic waste collection service. Once an operation exists, Sec. 62-791(b)(2) puts community composting operators on the hook for planning data: on the city's request, the operator must provide an estimate of the organic waste it expects to handle so the city can plan capacity under its SB 1383 program, and must respond to the city's request within 60 days.

Facility operators generally, including composting operations, owe the same 60-day response duty for information about available and potential new or expanded capacity under Sec. 62-791(b)(1).
