St. George, Utah, gets its paint options from the Washington County Solid Waste District, and all of them are at the Washington County Landfill, 330 N Landfill Rd. in the city of Washington. What you do depends on the kind of paint. Good latex can go to the landfill’s free Paint Exchange on any day the landfill is open. Latex that’s too old or too low should be dried at home and put in the trash. Oil-based paint, stain, lacquer, thinner and spray cans go only to the county’s household hazardous waste days, held twice a year. Utah has no PaintCare program, so paint stores don’t take leftover paint back.
Latex and oil-based paint go different ways
Washington County says water-based and latex paint should be dried out at home and put in your regular garbage once it’s completely solid. Only oil-based paint, stain and lacquer (and other hazardous waste) should go to the collection day. So most St. George households only need the collection day for oil-based products.
What the Paint Exchange will take
The exchange takes only water-based latex house paint that is more than a quarter full, still usable and opened within the last 2 years. It’s free to drop off and free to shop, and the county pitches it for school projects, crafts and home projects. If your can doesn’t qualify, the county says to dry it out at home or bring it to a hazardous waste day.
Hazardous waste only on two mornings a year
The county’s FAQ says it isn’t permitted to accept hazardous waste at the landfill, so it holds a hazardous waste day twice a year instead. The county’s 2026 dates were April 18 and Oct. 17, 8 a.m.–12:30 p.m., and the county warns the cutoff depends on volume. Each household can bring about 20 gallons or 200 pounds; big loads from residents, businesses or contractors are turned away.
Small businesses pay $3.32 a gallon at the exchange
The county’s Commercial page says small businesses that meet the “conditionally exempt small quantity generators” criteria, which it describes as producing less than 220 pounds a month, can drop paint at the Paint Exchange for $3.32 per gallon. Businesses can’t use the hazardous waste days. For oil-based or bigger loads, the county points businesses to Veolia Environmental Services at 801-294-7111.
The city’s Reuse Center is for yard waste
St. George’s Reuse Center at 575 East Brigham Road sounds like a place for leftover paint, but it isn’t. It takes green waste and sells compost, and it won’t take painted wood, household garbage or building materials. Call 435-627-4028 with Reuse Center questions; take paint to the county landfill instead.
