The ordinance is the second of three cannabis-related policies coming down the pipeline, after voters approved recreational use of marijuana last fall via Proposition 64. The council approved an outdoor cultivation ordinance in March; an ordinance regulating dispensaries is expected to be ready for consideration this summer. If approved, Davis would be one of the few cities in the region allowing manufacturing of volatile and non-volatile cannabis products. Non-volatile manufacturing typically involves blending, infusing or assembling cannabis products. Volatile manufacturing, by comparison, can require hazardous materials to extract or refine the raw cannabis product. Local laws already require conditional use permits for businesses that handle more than 500 pounds, 55 gallons or 100 cubic feet of gaseous hazardous materials. Volatile cannabis businesses that reach this threshold would be subject to “stringent safety standards,” according to a recent city staff report, covering noise, odor, fire hazard, fume, vapor and air pollution requirements. All commercial cannabis businesses — from testing sites to manufacturers — would have to stick to industrial, industrial administrative and research, and commercial service land-use areas. The majority of these are centered around Second Street in East Davis. The ordinance also would require cannabis businesses to operate on a wholesale-only basis, prohibiting any retail sales on site. The ordinance drops the state-permitted 600-foot distance between cannabis businesses and schools and day-care facilities.
