Understanding Hazardous Waste Regulations

What’s Involved in Determining Hazardous Waste

Wastes generated from the production and processing of marijuana must be evaluated to determine whether they qualify as hazardous waste under state and federal regulations. Per 40 CFR 262.11, each licensee is responsible for properly evaluating their waste and documenting those findings. Materials determined to be non-hazardous can be managed according to 19 CSR 100‑1.150.

Common types of hazardous waste produced at manufacturing, testing, and cultivation facilities include:

Butane
Ethanol
Isopropyl alcohol
Propane
Propylene glycol
Methanol
Vacuum pump oil

Properly Off-Gassing Biomass

Across the cannabis extraction industry, off-gassing is one of the most overlooked issues. Off-gassing is the process of releasing residual gases, such as butane, from cannabis biomass when solvent-based extraction takes place. Facilities may unknowingly dispose of material too soon, risking workplace safety and rejection by disposal facilities.

To maintain safety and compliance, specialized equipment is needed to manage these gaseous chemical agents effectively. Monarch Waste Co. helps clients address this challenge by providing butane-specific containment receptacles engineered for use within C1D1 extraction rooms.

Obtaining a Generator ID

Manufacturing, testing, and cultivation facilities must obtain an EPA Identification (EPA ID), managed by MO DNR, if a facility is producing more than the maximum monthly threshold for Very Small Quantity Generators (VSQGs). They can do so by filling out EPA Form 8700-12 and submitting it to an authorized state agency or EPA regional office.

If MO DNR inspects a facility and finds no hazardous waste determination has been documented, the facility may be cited for noncompliance.

At Monarch Waste Co., we help cannabis operators navigate their generator ID process, ensuring compliance and making them inspection-ready.

Staying Compliant and Sustainable

Materials identified as hazardous must be transported by a licensed hazardous waste provider in full compliance with DOT regulations.

Monarch's processes ensure compliance with all EPA, MO DNR, and DOT standards. With your hazardous waste properly transported and disposed of, you'll avoid being in violation and paying expensive fines.

We'll guide your facility through every step of the disposal process so you can rest assured your waste is properly stored and managed before pickup in a responsible way that doesn't harm the environment. At Monarch, we are committed to sustainability and moving the industry toward a more sustainable future.
