The Humboldt County Planning Commission voted 4-2 on Oct. 1 to approve Quantum Leasing LLC’s conditional-use-permit modification for a Rohnerville-area cannabis operation, adding cannabis distribution and non-volatile manufacturing to an existing cultivation project.
The county agenda identifies the project as PLN-2026-19563 on Assessor’s Parcel Number 203-231-003. It describes the existing operation as 9,792 square feet of mixed-light cultivation, including mature canopy and immature plant cultivation for propagation and research and development.
The approval does not show that Quantum has already received wastewater clearance for manufacturing. During the hearing, county planning staff said the manufacturing wastewater may not be suitable for the existing septic system and that Quantum must work with the North Coast Regional Water Quality Control Board and the county Division of Environmental Health on a wastewater-treatment plan before manufacturing starts. Staff also said the applicant would have to demonstrate how the wastewater requirement was addressed before beginning manufacturing, according to the recording of the Planning Commission meeting.
The proposed manufacturing would use ice water to extract cannabis material and a rosin press, and staff estimated less than 1,000 gallons of additional water use annually. The hearing record does not identify an Environmental Health clearance, an operating or onsite-wastewater permit, or a Water Board authorization for Quantum’s proposed manufacturing wastewater.
The commission also added conditions requiring commercial deliveries on weekdays from 9 a.m. to 3 p.m. on school days and requiring the applicant to join a road-maintenance association or show that it contributed a proportionate share of annual road-maintenance costs. Those conditions are separate from the wastewater requirement, which remains a prerequisite to manufacturing.
The available record also includes discussion of recent greenhouse-lighting complaints. County staff said the complaints were being addressed through the county’s compliance process, but the materials reviewed for this story did not include a latest inspection report, reinspection record or final correction notice. Claims made by neighbors at the hearing should not be treated as final county findings without those records.
