My jurisdiction just passed an ordinance allowing growing, selling, manufacturing, and testing of marijuana products. I get the fun of ensuring that all of these new facilities are code compliant. (overwhelming joy floods over me). :banghd The first problem I am facing is verifying compliance of the required mechanical exhaust and source capture systems for odor control in any facility. I am starting out by telling the applicant that the system needs to be designed professionally and specific to the building. My question to the group is will they need to design to the IMC chapter 4 for ventilation rates and chapter 5 exhaust systems? Or is this a separate beast that no one knows how to handle yet?
