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.
