Stage Gulch Organics Compost Facility (Project File Number UPE12-0031)

Permit Sonoma

Project Description

Use Permit for a commercial compost facility on approximately 17 acres located at 2535 Stage Gulch Road, Petaluma. The project proposes construction and operation of a circular-turned aerated pile (cTAP) composting system, designed to process 185,000 tons of organic materials per year. The Project would include construction of a concrete aerated pad for composting operations, and minor structures including a small office, operations control container, employee breakroom and bathroom, an entrance/exit scale, and parking. The Project also proposes to construct a Class A well with a 50-foot concrete seal, an 800-gallon septic tank and pump, and two sets of hydrants and standpipes (one for reclaimed City of Petaluma water and one for on-site reservoir water). Separate from the composting operation, an Agricultural Products Pad is proposed to allow for the development of custom blends, planter mixes, storage of amendments and stabilized compost, and other agricultural products for use in the local agricultural community.

Notice of Preparation and Virtual Public Scoping Meeting

Permit Sonoma is publishing a Notice of Preparation (NOP), which notifies responsible agencies and interested parties of its intent to prepare a Draft Environmental Impact Report (EIR) for the project, and invites agencies and interested members of the public to provide written input on the scope of the environmental analysis. The NOP describes the project that will be analyzed in the EIR and identifies areas of probable environmental effects.

Scoping Meeting

Due to the COVID-19 pandemic, the County held a virtual scoping meeting to provide an additional opportunity for agency staff and interested members of the public to submit comments, either written or verbal, on the scope of the environmental issues to be addressed in the EIR. The scoping meeting was held on Wednesday, December 16, 2020 from 6:30 p.m. to 7:30 p.m.

Members of the public can watch or listen to the meeting here:
