Cannabinoid Concentrates or Extracts. A processing site endorsed to make
cannabinoid concentrates or extracts:
not use Class I solvents as those are classified in the Federal Drug
Administration Guidance, Table I, published in the Federal Register on December
24, 1997 (62 FR 67377
(A) Only use a hydrocarbon-based solvent that
is at least 99 percent purity.
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
Cannabinoid Extracts. A processing site
endorsed to make cannabinoid extracts:
May not use pressurized canned flammable fuel, including but not limited to
butane and other fuels intended for use in camp stoves, handheld torch devices,
refillable cigarette lighters and similar consumer products
Process in a:
(i) Fully enclosed room clearly designated on
the current diagram of the registered premises.
(ii) Room and with equipment, including all
electrical installations, that meet the requirements of the Oregon Structural
Specialty Code, related Oregon Specialty Codes and the Oregon Fire
commercially manufactured professional grade closed loop extraction system
designed to recover the solvents and built to recognized and generally accepted
good engineering standards, such as those of:
(i) American National Standards Institute
Laboratories (UL); or
American Society for Testing and Materials (ASTM).
(C) 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 600 pounds per square inch.
(D) 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
(E) Have an emergency
eye-wash station in any room in which cannabinoid extract is being
(F) Have all applicable
material safety data sheets readily available to personnel working for the
Cannabinoid Concentrates. A processing
site endorsed to make cannabinoid concentrates:
(A) Use denatured alcohol.
(B) If using carbon dioxide, apply high heat
only use or store dry ice in a well ventilated room to prevent against the
accumulation of dangerous levels of carbon dioxide.
(A) A mechanical extraction
(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) A chemical extraction
process using the hydrocarbon-based solvent carbon dioxide, provided that the
process does not involve the use heat over 180 degrees or pressure.
