Posey County’s fall clear-out pulse for the west Tri-State is a monthly Tox-Away — not a one-off festival weekend. After River Days / Kunstfest / Autumnfest traffic, garage chemicals in Mount Vernon IN, New Harmony, and Poseyville still need a dated drop. Next window: Thu Oct 1 in Mount Vernon IN.
Why care + what to do this week
Mount Vernon IN / Posey homeowners: if oil-based paint, solvents, pesticides, pool chemicals, or mercury items are sitting in the garage, put them aside for Tox-Away Thu Oct 1, 2–6pm at the Recycling Center. No dated county shred or tire amnesty posted for Sep–Oct 2026 — don’t invent one; use the monthly HHW program and year-round centers.
Tagged items
Posey County Tox-Away Day (monthly) — first Thursday March–December · next Thu Oct 1, 2026 · 2–6pm
Mount Vernon Recycling Center, 400 Brown St / Lower New Harmony Rd (Mount Vernon IN). Household hazardous waste for oil-based paints, solvents, pesticides, pool chemicals, mercury items, and similar. Soft look-ahead: next after Oct 1 under the published rule is Thu Nov 5 (soft — beyond the preferred 30-day core).
Year-round context (soft, not a dated event)
District also runs year-round recycling / yard sites; Continental Tire community recycle was Apr 25, 2026 (past). Mount Vernon IN Street Dept lists leaf collection as a duty, but no 2026 start date was found — do not invent leaf days.
Soft note
Festival ladder (River Days, Kunstfest, Poseyville Autumnfest) is traffic/décor, not disposal — already covered in festival digests. This hub stays on clear-out only. Soft permits only — confirm with the county before you go.
