Project Description

Request for Qualifications to Provide On-Site Composting Workshops in Sonoma County

May 21, 2026

Zero Waste Sonoma (AGENCY) is seeking qualifications for an individual or entity (PROPOSER) to provide technical, on-site composting workshops to benefit orchards, vineyards, schools, community gardens, and other crop growers in Sonoma County. The purpose of this project is to encourage small to medium-scale local composting and reduce greenhouse gas emissions from transporting agricultural materials and/or food scraps out of the county for disposal or composting. Since growers must often pay to haul finished compost back into the county, empowering growers to make their own compost will also help reduce costs, increase compost use and local nutrient cycling, and increase community-resiliency.

The AGENCY will select one proposal to award a $45,000 agreement to provide technical, on-site composting workshops. The term of the agreement is suggested to be June 19, 2026 – June 1, 2027. PROPOSERs may propose a shorter term but not longer. The awarded PROPOSER will enter into a professional services agreement (Exhibit A) with the AGENCY for the project. The PROPOSER’s scope of work will be negotiated and finalized with the AGENCY before inclusion into the agreement for execution.

1. INTENT AND BACKGROUND

1.1 Definitions

This section contains definitions that are used throughout this RFQ.

AGENCY:

Zero Waste Sonoma (also known as the Sonoma County Waste

Management Agency) is a joint powers authority composed of the

County of Sonoma and the nine incorporated jurisdictions within

Sonoma County: Cloverdale, Cotati, Healdsburg, Petaluma, Rohnert

Park, Santa Rosa, Sebastopol, Sonoma, and Windsor.

COUNTY:

The County of Sonoma, a political subdivision of the State of California,

primarily overseeing the unincorporated areas within Sonoma County.

Sonoma County:

The geographical area of Sonoma County, encompassing all

incorporated and unincorporated areas.

1.2 Overview of Requested Services

Zero Waste Sonoma (AGENCY) is seeking qualifications for an individual or entity (PROPOSER) to provide

technical, on-site composting workshops to benefit orchards, vineyards, schools, community gardens,

and other crop growers in Sonoma County. The purpose of this project is to encourage small to medium-

scale local composting and reduce greenhouse gas emissions from transporting agricultural materials

and/or food scraps out of the county for disposal or composting. Since growers must often pay to haul

finished compost back into the county, empowering growers to make their own compost will also help

reduce costs, increase compost use and local nutrient cycling, and increase community-resiliency.

Since SB 705 (2003 Florez) phased out agricultural burning in California, growers must pursue alternative

methods to dispose of agricultural waste. SB 279 (2025 McNerney) went into effect on January 1, 2026,

and allows more growers to compost agricultural wastes on-site without needing to apply for

compostable material handling permits from the state. Under SB 279, growers may have a total amount

of feedstock and compost on-site at any one time of up to 200 cubic yards, and they may give away or

sell up to 5,000 cubic yards of compost product annually.

All data and information furnished by the AGENCY or referred to in this RFQ are furnished for the

PROPOSER's convenience. The AGENCY does not guarantee that such data and information are accurate

and assumes no responsibility whatsoever as to their accuracy or interpretation. PROPOSERs shall

satisfy themselves as to the accuracy or interpretation of all such information or data.

2. BUDGET

The AGENCY will select one proposal to award a $45,000 agreement to provide technical, on-site

composting workshops. The term of the agreement is suggested to be June 19, 2026 – June 1, 2027.

PROPOSERs may propose a shorter term but not longer. The awarded PROPOSER will enter into a

professional services agreement (Exhibit A) with the AGENCY for the project. The PROPOSER’s scope of

work will be negotiated and finalized with the AGENCY before inclusion into the agreement for

execution.
