Section 3 AAC 306.555 - Production of marijuana concentrate(a) Before producing marijuana concentrate for sale, a marijuana product manufacturing facility shall develop standard operating procedures, good manufacturing practices, a safety plan, and a training plan for each individual employed in an extraction process.(b) A marijuana product manufacturing facility may create marijuana concentrates only as follows: (1) water-based marijuana concentrate may be produced by extracting cannabinoids from marijuana by using only water, ice, or dry ice;(2) food-based marijuana concentrate may be produced by extracting cannabinoids from marijuana through the use of propylene glycol, glycerin, butter, olive oil, or other typical cooking fats; infused dairy butter, oils, or fats derived from natural sources may be used to prepare infused edible products;(3) solvent-based marijuana concentrate may be produced using the hydrocarbons N-butane, isobutane, propane, or heptane or other solvents or gases the board approves that exhibit low to minimal potential human health-related toxicity; approved solvents must be of at least 99 percent purity and must be used (A) in a professional grade closed-loop extraction system designed to recover the solvents;(B) in an environment with proper ventilation; and(C) with control of all sources of ignition if a flammable atmosphere is or may be present.(c) A marijuana product manufacturing facility using a professional grade closed-loop gas extraction system shall ensure that (1) each vessel is used in compliance with the manufacturer's stated pressure ratings;(2) any carbon dioxide used is of at least 99 percent purity;(3) a person using a solvent or gas to extract marijuana concentrate in the closed-loop system is fully trained on how to use the system, has direct access to applicable material safety data sheets, and handles and stores the solvent and gas safely;(4) a licensed engineer has certified that the professional grade closed-loop system was commercially manufactured, is safe for its intended use, and is built to codes of recognized and generally accepted engineering practices; and(5) any professional grade closed-loop system, and other equipment and facilities used in the extraction process are approved for their use by the local fire code official and meet any applicable fire, safety, and building code requirements.(d) A marijuana product manufacturing facility may use heat, screens, presses, steam distillation, ice water, and other methods without employing solvents or gases to create (4) infused dairy butter, oils, or fats derived from natural sources; or(e) A marijuana product manufacturing facility may use food-grade glycerin, ethanol, and propylene glycol solvents to create extracts. All ethanol must be removed from the extract in a manner to recapture the solvent and ensure that it is not vented into the atmosphere.Eff. 2/21/2016, Register 217, April 2016; am 4/16/2023, Register 246, July 2023Authority:AS 17.38.010
