What Can I Bring?
The small business program accepts a wide range of labeled hazardous wastes; for example, most common consumer type building maintenance products (e.g., painting, cleaning, gardening, and auto), as well as pure chemicals used in business or laboratory applications are accepted. If you have a question regarding the acceptability of your wastes, please call (800) 646-1431.
What Can’t I Bring?
WE DO NOT ACCEPT:
- Non-hazardous wastes
- Sharps and Medical waste (needles, scalpels, etc.)
- Medications and Pharmaceuticals
- Radioactive material
- Unknown or unlabeled chemicals
- PCB wastes greater than 50 ppm
How Much Can I Bring?
State law limits the total amount your business may transport up to 27 gallons or 220 pounds per month. No individual container may be over 5 gallons or 50 pounds in weight.
How to Package
All materials must be labeled and packaged in sturdy, non leaking containers. Tighten all lids. No individual container may be greater than 5 gallons or 50 pounds in size. Package all wastes in original containers if possible. If you have a leaking container, place it in a larger container no larger than 5 gallons (such as a plastic bucket available from hardware stores). Small leaking containers can be placed individually inside double ziplock bags. Always include an original label, MSDS or note with information that identifies the waste contents. Do not mix different wastes in the same container.
How to Transport
Place the materials upright in your vehicle and prop them so they will not slip or tip over. For safety, transport the materials in your vehicle’s trunk or truck bed, away from the passenger compartment. No Hazardous Waste Manifest or transporter registration is required for eligible businesses.
What Happens Next?
Upon arriving at the facility, you will be directed into an unloading area where District staff will verify the waste amount, collect your fee, and unload your wastes. We are a full service operation; please stay in your vehicle at all times. Your waste will be checked against your inventory, weighed if necessary, and the remainder of your Waste Inventory and Certification Form will be completed and signed by our staff and your employee who is dropping the waste off. Please retain your copy of the completed, signed Waste Inventory and Certification Form for a minimum of three years, which will document your proper disposal of hazardous waste.
