January: Hazardous Waste Collection Event Scheduled for April 19 at Fairgrounds

Boulder County residents can safely dispose of household hazardous waste including paint, solvents, pesticides, batteries, and electronics at a free collection event on Saturday, April 19 at the Boulder County Fairgrounds. No appointment is necessary. Commercial waste is not accepted.

The Public Health processed over 11,271 applications last year, with an average processing time of 16 business days. Staff are available at the Louisville office Monday through Friday from 8:00 AM to 4:30 PM.

The program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.

Background

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 91% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

The Board of County Commissioners will review progress on this initiative at their April 30 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

Details

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $399,000, making it one of the largest collaborative efforts in the county’s history.

Water quality monitoring at 11 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Public Health publishes quarterly water quality reports on the Boulder County website.
