Fuels Illegal in Garbage & Drains Hazardous Waste Fuels are accepted at the West Contra Costa County Household Hazardous Waste Facility in appropriate containers that are labeled (i.e., “Gasoline”), will not leak, and properly contain fumes. Note that containers will not be returned. State regulations limit the transportation of HHW materials (inlcluding gasoline) to 15 gallons or 125 pounds per vehicle per visit. Individual containers are limited to a 5 gallon capacity. Therefore, no more than 3 5-gallon containers will be accepted for drop-off. Never Pour Down the Drain A few spilled drops of gasoline can contaminate large quantities of clean drinking water. Never pour gasoline on the ground or down the drain. It will harm the environment and could lead to a fire or explosion. Store Only 25 Gallons or Less Fire codes allow homeowners to store up to 25 gallons in containers, which hold no more than five gallons each. Store Safely Always store away from ignition sources, such as heat, sparks or flames. Store away from your house in containers with approved labels and lids that prevent spillage.

Lawnmowers, leaf blowers and chainsaws all run on gasoline. Give to Your Neighborhood Landscapers Offer unwanted gas to landscapers working in your neighborhood. They may be happy to take it off your hands, but make sure to disclose the fuel’s age.
