PROGRAM RULES AND REQUIREMENTS
How to prepare your HHWs for transport and safe management
Limit: 10 gallons or 50 pounds of waste per appointment
State regulations prohibit you from transporting more than 10 liquid gallons or 50 solid pounds of hazardous waste in your vehicle at one time. If you have more than 10 gallons or 50 pounds of waste, you can schedule multiple appointments.
If your waste exceeds this amount:
- Estimate the amount of actual product in the container.
- Make one appointment per vehicle for every 10 gallons or 50 pounds of hazardous waste.
- Make additional appointments as needed.
- Drop off 10 gallons on the first appointment, return home and collect the remaining 10 gallons, then return to the drop off location to dispose of your remaining trash on your second appointment.
There is no limit to the number of appointments you can make per event, but you cannot carry more than 10 gallons per vehicle load/appointment.
Limitation: the program cannot accept containers larger than 5 gallons
The program only accepts containers of 5 gallons or less. If you have waste in an oversized container larger than 5 gallons:
- Get buckets with lids that are no larger than 5 gallons.
- Transfer the waste from the large containers to the 5 gallon buckets and secure the lid.
- Label 5 gallon pails with original product name and description.
IMPORTANT: KEEPING YOURSELF, YOUR FAMILY AND COUNTY EMPLOYEES SAFE. DO NOT MIX ANY WASTE.
Prepare for your appointment by following these steps
- Keep your waste in their original sealed containers.
- For waste in original containers with labels intact and legible, place items in boxes or crates – best to keep waste containers upright for safer transportation, avoiding spills. Do not use plastic bags.
- For waste without a label, or not in the original containers, please tell county staff what it is, or attach a label indicating what it is.
- Do not place items in plastic garbage bags.
- For fragile or leaking containers, place them in a larger container such as a large bucket with a secure lid to safely contain the leaking material.
- Place waste containers upright in cardboard boxes or sturdy trash cans.
- You can line the box or bin with plastic – don’t use plastic bags alone.
- Place the prepared waste in the back of your vehicle.
- If you would like to keep your waste container (for example, a red gas can), make an appointment at a collection event in San Mateo.
- Remove all other items not intended for disposal from the back of your vehicle.
- Avoid bringing pets or plan to keep them safe.
- REMEMBER: NEVER MIX WASTE. IT’S DANGEROUS.
