Update: Hazardous Waste Collection Event Scheduled for April 19 at Fairgrounds (2024)

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.

Environmental review of the project area near Sunshine Canyon Drive found 8 sensitive species and 2 wetland areas requiring mitigation. The Parks & Open Space worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

The Bald Mountain open space property encompasses 968 acres and features 13 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Next Steps

The application deadline is June 28, 2026. Late applications will be accepted on a space-available basis. Incomplete applications will be returned with a list of missing items. Average review time is 11 business days.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $6,000, making it one of the largest collaborative efforts in the county’s history.

How to Participate

Residents in the Louisville area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Parks & Open Space at (303) 441-3009 to verify eligibility and requirements.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 47% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
