20 CAR § 810-1205. Manufacturing and processing of cannabinoid concentrates and cannabinoid extracts.
(a) Licensed facilities producing cannabinoid concentrates and extracts shall:
(1) Not use solvent classified as “Class 1” by the United States Food and Drug Administration Guidance, Table 1, published in the Federal Register on December 24, 1997, 62 Fed. Reg. 67,377;
(2) Only use a hydrocarbon-based solvent that is at least 99 percent (99%) purity;
(3) Only use a nonhydrocarbon-based solvent that is food grade;
(4) Work in an environment with proper ventilation, controlling all sources of ignition where a flammable atmosphere is or may be present; and
(5) Use only potable water and ice made from potable water in processing.
(b) Licensed facilities producing cannabinoid extracts shall:
(1) Not use pressurized canned flammable fuel, including but not limited to butane and other fuels intended for use in:
(A) Camp stoves;
(B) Handheld torch devices;
(C) Refillable cigarette lighters; and
(D) Similar consumer products;
(2) Process only in a fully enclosed room clearly designated on the floor plan of the licensed facility;
(3) Ensure that all processing rooms and equipment, including all electrical installations, comply with applicable electrical codes and fire codes;
(4) Use a professional grade closed loop extraction system designed to recover the solvents and built to recognized codes and generally accepted engineering standards, such as those of:
(A) American National Standards Institute (ANSI);
(B) Underwriters Laboratories (UL); or
(C) The American Society for Testing and Materials (ASTM);
(5) 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 (600 lbs.) per square inch;
(6) Have equipment and facilities used in processing approved for use by the local fire code official;
(7) Have a licensed engineer certify that the closed-loop system was commercially manufactured, and is safe for its intended purposes;
(8) Have an emergency eye-wash station in any room in which cannabinoid extract is being processed; and
(9) Have all applicable material safety data sheets readily available in processing areas.
(c) Licensed facilities producing cannabinoid concentrates may use a:
(1) Mechanical extraction process;
(2) Chemical extraction process using a nonhydrocarbon-based or other solvent, such as:
(A) Water;
(B) Vegetable glycerin;
(C) Vegetable oils;
(D) Animal fats;
(E) Isopropyl alcohol; or
(F) Ethanol; and
(3) Chemical extraction process using the hydrocarbon-based solvent carbon dioxide, provided that the process does not involve the use of pressure or heat over one hundred eighty degrees (180°).
(d) Licensed facilities producing cannabinoid concentrates shall:
(1) Not use denatured alcohol;
(2) Not apply pressure or heat over one hundred eighty degrees (180°) if using carbon dioxide; and
(3) Only use or store dry ice in a well-ventilated room to prevent against the accumulation of dangerous levels of carbon dioxide.
