Everything you need to get rid of leftover paint responsibly in Gillette.
4 N Landfill Rd, Gillette, WY 82716
The county says the landfill is 11 miles north of Gillette on North Highway 59, so this isn’t a quick in-town stop. Pull onto the inbound scale closest to the scale house; the attendant will direct you to the right area. Because the two county pages give different Saturday hours, go on a weekday or call ahead on Saturday.
Your state doesn’t have a PaintCare program, so stores here don’t take paint for free. These are the public drop-off programs PaintCare’s map lists, closest first. Most only serve their own residents and some charge a fee. Call before you go.

From PaintCare’s drop-off map ↗, updated October 6, 2026. Hours and limits are PaintCare’s. Distances are straight-line, not driving.
Skip the drive. Open the cans, stir in kitty litter, ashes or hardener, let them dry solid and put them in your garbage dumpster at home.
Take them to the North Landfill on a weekday between 7:30 a.m. and 5 p.m. Pull onto the inbound scale and tell the attendant what you have; they’ll direct you. It’s free for Campbell County residents.
The county’s two pages disagree: 11 a.m.–4:30 p.m. on the hazardous waste page, 7:30 a.m.–1 p.m. on the landfill page. Arriving between 11 a.m. and 1 p.m. fits both, but call 307-682-1153 first.
Strap or tarp it to avoid the $25 residential fee. Each Campbell County address gets 12 fee-waived household-waste dumps a year, up to one ton each, with proof such as a utility bill or vehicle registration that matches your driver’s license.
Dry out latex paint and put it in your home garbage; Campbell County doesn’t take liquid latex. Take oil-based paint and spray paint to the Campbell County Landfill, 4 N Landfill Rd., which the county says is 11 miles north of Gillette on North Highway 59, weekdays 7:30 a.m.–5 p.m.; it’s free for county residents. Saturday hours differ between the county’s pages, so call 307-682-1153 before a Saturday trip.
Gillette, Wyoming (Campbell County) splits paint by type. Oil-based paint and spray paint go free to the Campbell County Landfill, which the county says is 11 miles north of Gillette on North Highway 59. Latex paint isn’t taken there as a liquid: you dry it out and throw it away with your household trash. Wyoming has no PaintCare program.
The county says to open latex cans and let the paint dry completely. Hardener from a hardware store speeds it up, and so does mixing in kitty litter or ashes. Then put it in your garbage dumpster at home or take it to the landfill with your household trash.
The hazardous waste drop-off is at the North Landfill, which the county puts about 11 miles north of Gillette. From Skyline Drive and 2nd Street, the county says to go north about 7 miles to Highway 59, turn right and go another 4 miles to North Landfill Road on the left. Pull onto the inbound scale closest to the scale house, and the attendant will direct you.
The county’s hazardous waste page says Saturday 11 a.m.–4:30 p.m. The landfill’s main page says Saturday 7:30 a.m.–1 p.m. If you can only go on Saturday, call 307-682-1153 first, or go on a weekday.
PaintCare’s non-program listing still shows a South Facility (CARE) at 909 Westover Rd. taking hazardous waste weekdays 10 a.m.–6 p.m. A 2017 county FAQ said hazardous waste could go to Westover Road for a while, but that by summer 2018 everything except CARE recyclables must go to the North Landfill. The county’s current hazardous waste page names only the landfill at 4 N Landfill Rd. The county hasn’t said outright that Westover stopped, so call 307-682-1153 before you try it.
The landfill charges $25 for a residential load (and $50 for a commercial one) that arrives untied or untarped. Strap down the box of cans, especially for the highway drive north.
Wyoming has no PaintCare program, so stores don’t take back paint. Dried latex can go in your trash. Give usable paint to someone who can use it. The City of Gillette’s Solid Waste page doesn’t mention paint; it says all trash must be bagged and the lid must close. Wyoming DEQ says never to pour chemicals into storm drains or street gutters. Businesses need a private hazardous waste company, since PaintCare’s non-program listing shows the county site as households only.
Keep oil-based paint and spray cans in their original containers with lids on. Bring your driver’s license and a current utility bill or vehicle registration showing your Campbell County address; the scale house asks for these for fee-waived dumps, and the hazardous waste page doesn’t list its own proof rule. Tarp or strap the load.
Full preparation checklist →To the Campbell County Landfill, 4 N Landfill Rd., 11 miles north of Gillette on North Highway 59. It’s free for county residents, weekdays 7:30 a.m.–5 p.m.
Yes, once it’s completely dry. Open the can and let it dry, or mix in hardener, kitty litter or ashes. Then put it in your home garbage or take it to the landfill with household trash.
Yes. The county lists spray paint with oil-based paint on its free hazardous waste list.
Yes, with three closures the county lists: Wednesday, Nov. 11 (Veterans Day), Thursday, Nov. 26 (Thanksgiving) and Saturday, Nov. 28 (Employee Appreciation Day).
Probably not. PaintCare’s non-program listing still shows it, but a 2017 county FAQ said everything except CARE recyclables would move to the North Landfill by summer 2018, and the county’s current page names only the landfill. Call 307-682-1153 to check.
October 16, 2026: read Campbell County’s Hazardous Household Waste, Landfill, Landfill FAQ and Fee-Waived Dumping pages, a 2017 county landfill FAQ (PDF), the City of Gillette Solid Waste page, Wyoming DEQ’s nonpoint source page and the PaintCare locator data (two Campbell County records, both non-program sites). Unresolved: the hazardous waste page lists Saturday 11 a.m.–4:30 p.m., which matches the 2017 FAQ, while the landfill page lists Saturday 7:30 a.m.–1 p.m. PaintCare’s non-program listing shows 909 Westover Rd. with weekday 10 a.m.–6 p.m. hours (the 2017 CARE Center hours) and phone 307-682-9499; the current county page names only the North Landfill, the 2017 FAQ said everything but CARE recyclables would move north by summer 2018, and we didn’t confirm whether Westover still takes anything, so the guide calls the listing likely out of date rather than closed. No paint quantity limit or residency-proof rule is published for hazardous waste. No business option for paint is published.
