Division 25 - RECREATIONAL MARIJUANA
Section 845-025-3260 - Cannabinoid Concentrate and Extract Processor Requirements

(A) Only use a hydrocarbon-based solvent that is at least 99 percent purity.

(B) Only use a non-hydrocarbon-based solvent that is food-grade.

(C) Work in an environment with proper ventilation, controlling all sources of ignition where a flammable atmosphere is or may be present.

(D) Use only potable water and ice made from potable water in processing.

(E) If making a concentrate or extract that will be used in a cannabinoid edible, be endorsed as a cannabinoid edible processor and comply with OAR 845-025-3250.

(A) Provide proof in a form and manner specified by the commission that the premises proposed to be licensed has received a Certificate of Occupancy for the intended use issued by the appropriate local building official;

(B) Must list all equipment used in extraction and, if applicable, provide proof that equipment and process has been inspected by a:

(A) Process in a fully enclosed room clearly designated on the current diagram of the licensed premises.

(B) Process, if using hydrocarbon solvents, in a room with equipment, including all electrical installations that meet the requirements of the Oregon Structural Specialty Code, related Oregon Specialty Codes and the Oregon Fire Code.

(C) Use a professional grade closed loop extraction system designed to recover the solvents and built to codes of recognized and generally accepted good engineering standards, such as those of:

(D) If using carbon dioxide in processing, use a professional grade closed loop carbon dioxide gas extraction system where every vessel is rated to a minimum of six hundred pounds per square inch.

(E) For extraction system engineering services, including but not limited to consultation on and design of extraction systems or components of extraction systems, use the services of a professional engineer registered with the Oregon State Board of Examiners for Engineering and Land Surveying, unless an exemption under ORS 672.060 applies.

(F) Have an emergency eye-wash station in any room in which cannabinoid extract is being processed.

(G) Have all applicable material safety data sheets readily available to personnel working for the processor.

(H) If subject to inspection by local and state fire officials, maintain the premises' Certificate of Occupancy at intervals specified by the fire official.

(A) Use denatured alcohol.

(B) If using carbon dioxide, apply high heat or pressure.

(A) A mechanical extraction process; or

(B) A chemical extraction process using a nonhydrocarbon-based or other solvent, such as water, vegetable glycerin, vegetable oils, animal fats, isopropyl alcohol or ethanol.

(C) An extraction process using the solvent carbon dioxide, provided that the process does not involve the use of heat over 180 degrees (Fahrenheit) or pressure.
