THE LOCAL ANSWERDry latex paint with kitty litter or sand, bag it and put it in your regular garbage; that's the city's year-round rule. Save oil-based paint, thinner and shellac for the city's free collection day, listed for spring 2027 from 9 a.m. to 1 p.m. at 1st St. S and 3rd Ave. S. It's for Great Falls residents only, so businesses and people outside the city need another option.
Great Falls, Montana, has no year-round paint drop-off. The city's Public Works Environmental Division and Veolia North America run a free household hazardous waste collection day for city residents, and the next one is listed for spring 2027. Latex paint isn't taken at that event; the city wants it dried and put in the garbage. Montana has no PaintCare program, so there is no PaintCare store drop-off network here.
Latex and oil-based go different ways
Great Falls splits paint by type. Latex or water-based paint is dried and goes in your garbage container. Oil-based paint, paint thinner and shellac must wait for the collection day. The event turns latex away, so drying it at home is your only latex option here.
Get there early on collection day
The event runs on a set budget. The Electric reported $50,000 for April 2026, paid from sewer and storm drain funds, and the city says it stops taking waste once the truck is full. The Electric reported that in past years some people near the end were turned away when the money ran out. Arrive close to 9 a.m.
Dried latex can also ride to High Plains Landfill
If you're already hauling a load, the city's Environmental Division manager told KRTV in 2025 that latex paint can go to the landfill as long as it isn't liquid. High Plains Landfill is at 142 Powerline Rd. in Floweree. Strap or tarp the load; the city says a $10 fine can apply.
Rural Cascade County sites aren't for paint
Cascade County's staffed rural collection sites (Armington, Cascade, Fort Shaw, Hardy Creek, Monarch, Stockett, Ulm and Vaughn) take household waste only, and county punch cards aren't valid for special waste. The county sends site questions to Republic Services (406-770-4441). They are not a substitute for the city's hazardous waste day.
No paint swap like Helena's
PaintCare's locator data shows a City of Helena Latex Paint Exchange (a non-program listing) but no Great Falls site. The city's own list of year-round options points latex to the trash and oil-based paint to the collection day. For still-good paint, give it to a neighbor or ask a reuse charity the city names, such as the Habitat for Humanity ReStore at 816 20th St. N (406-453-2173), whether it takes paint.
