Section 403.1 of the IMC adopted in section 22-276 of this Code is amended by adding the following:

A plan for ventilation of a marijuana business and hemp manufacturing facilities that describes the odor mitigation systems that will be used to prevent any odor of marijuana or hemp off the premises of the business or facility must be submitted to the city for review. No odor mitigation plan is required for a retail marijuana store unless the odor of marijuana can be detected on the exterior of the licensed premises, then the retail marijuana store must take steps, up to and including an odor mitigation plan, to prevent any detection of the odor of marijuana on the exterior of the license premises. For marijuana cultivation facilities and licensed research businesses, such plan shall also include all ventilation systems used to control the environment for the plants and describe how such systems operate.

The outdoor ventilation rate required for each marijuana business and hemp manufacturing facility will be as follows:

(1) For marijuana cultivation facilities and licensed research businesses, eight persons per 1,000 square feet with a ventilation rate of 60 cubic feet per minute per person;

(2) For the licensed premises for marijuana transporters, marijuana product manufacturers, hemp manufacturing facilities, marijuana testing facilities, and licensed research businesses, eight persons per 1,000 square feet with 15 cubic feet per minute per person.
