PJR-116 Small-Scale Agricultural Processing Facility Application

Agricultural processing includes those activities and processes conducted on a farm which change the unprocessed agricultural commodity from its natural state to a different form; examples include, but are not limited to, processing, milk into cheese, fruit into jam, olives into olive oil. Though most agricultural processing involves the processing commodities into food or beverage for human consumption, commodities may be processed into non-food items as well.

Though larger agricultural processing facilities, or processing facilities in the AR Zoning District, are required to obtain a conditional use permit approval prior to commencement, some small-scale operations in the LIA, LEA, DA, and RRD Zoning Districts may be administratively approved and authorized through this faster, less expensive, zoning permit application if they comply with the approval criteria and performance standards attached. However, this application form may not be used for operations which process meat, alcoholic or cannabis products.

To be approved, the applicant must submit a complete application to Permit Sonoma. An agricultural processing facility which does not meet all of the standards attached, either initially or on an on-going basis, will not be considered for administrative approval and a conditional use permit must be obtained.

The applicant/operator is responsible for complying with requirements of Federal, State and local law which apply to the type of agricultural processing proposed. These could include: permits and licenses, food safety laws, building, well, septic, fire, and accessibility requirements. Prior to applying, applicants should thoroughly research all the requirements applicable to their proposed processing facility and conduct the necessary preliminary investigations and cost estimates to assure that their business plan takes into account all costs associated with start-up and operation of the processing facility and that full compliance is feasible. In some cases, a project’s feasibility and approval can be significantly affected by costs related to adequate water supply, waste disposal, and building code compliance. Applicants are encouraged to consult with County staff regarding requirements of the County Code. The County’s Agricultural Ombudsman at the University of California Cooperative Extension can also lend assistance in determining what other Federal or State permits may be required or providing agency contacts.

The applicant submits a complete zoning permit application to Permit Sonoma in person at the zoning cubicle (mail in applications are not allowed). Permit Sonoma will assign a project planner to review the application and verify that it is complete and that the proposed processing facility and operation conforms with the approval standards and requirements.

Permit Sonoma will require that verification be submitted to confirm that the other applicable regulatory agencies and divisions have determined that the proposed operation will comply with their requirements and have granted any prerequisite approvals, permits, licenses and clearances required by their agencies. Once compliance is verified, Permits will issue a zoning permit approval letter to the applicant/operator.

A complete application is required and must include all of the following documents:

1. Zoning permit application PJR-001 (PDF: 82 kB) signed by all property owners.
2. Signed indemnification form PJR-011 (PDF: 72 kB)
3. Signed Small-Scale Agricultural Processing Facility Affidavit PJR-117(PDF: 34 kB)
4. 8 ½ inches x 11 inches site plan, drawn to scale, that clearly identifies all structures on the property, the structure where the small-scale agricultural processing facilities will be conducted, the proposed water supply and septic area as well as any areas to be used to manage or dispose of processing waste. The site plan should show access to a public road and indicate the parking and loading areas. The site plan should also show any adjacent wells, residences, or streams in the proximity of the operation.
5. 8 ½ inches x 11 inches floor plan, drawn to scale, of the proposed agricultural processing facility, including any outdoor or covered work or loading areas. Proposed facilities may be repurposed from existing structures or newly built under the appropriate building permits.
6. Written proposal that describes the proposed type, scale and intensity of the processing facility. The proposal should address each of the approval and performance criteria and provide adequate explanation, data or supplemental documentation to verify how the proposed facility complies with each. It should also indicate the percentage of processing ingredients produced by the operator and the typical source and delivery mechanism for offsite ingredients, the number of employees, and any plans for public visitation of the facility.
7. Waste Management Plan indicating how all waste by-products of the processing activities, such as cheese whey, pits, pulp, etc., will be stored, handled and reused or disposed of. This Plan should characterize the volumes and types of waste generated, and the operational measures that are proposed to manage the wastes in an environmentally sound manner which does not result in nuisance complaints or health hazards. Where waste discharge is within the jurisdiction of a Regional Water Quality Control Board, the owner or operator shall provide documentation of Waste Discharge Requirements, or waiver thereof, and shall comply with applicable discharge and monitoring conditions.
8. Verification from a registered Civil Engineer or Registered Environmental Health Specialist indicating that the type and volume of waste discharges to any existing or proposed septic systems which may serve the facility do not exceed the design, capacity and loading restrictions of the system.
9. Submit documentation that any existing or proposed well and water system serving the proposed processing facility will comply with applicable water well requirements in Chapter 25b of the County Code. The water system must also meet any performance standards and/or improvement requirements from other regulatory agencies.
