How to Start
All participants in the CESQG program MUST HAVE an EPA identification number unless you are only bringing universal waste such as fluorescent bulbs, batteries, and electronic waste.
- To apply for a permanent ID number, fill out Department of Toxic Substances Control Form 1358.
- To apply for a temporary ID number, call the California Environmental Protection Agency (CAL-EPA) at 1.800.618.6942.
- If your business already has an EPA ID Number, go to the next step.
Fill Out and Return the Proper Forms
The enclosed Small Business Program Waste Inventory and Self-Certification Form is a legal document attesting to the fact that your business meets the criteria of a Conditionally Exempt Small Quantity Generator. The inventory sheet will be used to schedule your appointment and determine your total disposal costs based on inventory of material you plan to bring to the facility. A Material Safety Data Sheet (MSDS) may be requested for some wastes.

How Much Does it Cost?
Delta Diablo (District) has established unit rates for most waste streams (see the Fee Schedule). District staff will estimate the costs based on the Waste Inventory and Self-Certification Form submitted by the small business. The cost estimate will be included on the form when the District gives you an appointment time.
How Much Can I Bring?
State law limits an employee of your business to transport up to 220 pounds (about 27 gallons of liquid of average weight) of hazardous waste, or up to 2.2 pounds of acutely hazardous waste. No individual container may be over 5 gallons or 50 lbs in weight.
How to Package
Package all wastes in original containers if possible. If you have a leaking container, place it in a larger container (such as a plastic bucket available from paint or hardware stores); small leaking containers can be placed individually inside double, ziploc bags. Include an original label, MSDS, or a note with as much information as possible about the material (including the brand name and ingredients). Do not mix different wastes in the same container. We can only empty used motor oil and antifreeze containers "while you wait", so package all other wastes in containers that can be left for disposal. Remember, no individual container may be over 5 gallons or 50 lbs in weight.
How to Transport
Place the materials upright in your vehicle and brace them so they will not slip or tip over. For safety, transport the materials in your vehicle's truck or truck bed, away from the passenger compartment. Remember, no individual container may be over 5 gallons or 50 lbs in weight, and a copy of the variance must accompany the waste at all times during the transport.
Upon Your Arrival
Upon arriving at the facility, pull up into the off-loading area, and turn off your vehicle. We are a full-service operation and our staff will offload your waste; please stay in your vehicle at all times. Your waste will be checked against your Waste Inventory and Self-Certification Form, signed-off by staff, and fees collected (check or money order only). A copy of the Waste Inventory and Self-Certification Form will be provided for your records. Please keep the form for a minimum of three years to document proper disposal of your hazardous waste.
