In 1993 the Missoula Valley Water Quality District held it's first Household Hazardous Waste Collection Event ("HazWaste Days").  That event was such a success that the decision was made to hold a collection event annually and up until 2017 the Water Quality District has held this event every September.  Last year's event would have marked the 25th anniversary of "HazWaste Days"; however, the event was cancelled with hopes that the new year-round facility would be up and running by early 2018.  Due to unexpected delays the facility is now not expected to be open until late 2019 or even early 2020. 

Since the 2017 event was cancelled the decision was made to resume our collection event this year and that was held on the 21st and 22nd of September. We would like to thank everyone who came out for this event making it one of the County's most successful.

Many unwanted hazardous and toxic materials are accepted at this event from Missoula County Residents for no charge, including oil-based paints and stains, paint thinner, degreasers, gasoline, other flammable liquids, aerosol paints, fertilizer, non-alkaline household batteries (alkaline batteries can be thrown away), used motor oil (courtesy of Republic Services -up to 15 gal.), antifreeze and up to 6 fluorescent tubes (no bulbs -- see year-round options, below).

Items accepted for a fee include pesticides, caustics, strong acids and chlorinated solvents. The fee charged covers approximately 25% of our costs for shipping and disposing of the waste.  

Businesses and out-of-county residents will be charged our costs for disposal of all waste.

Since the permanent facility opening has been delayed and we can only offer a collection event once a year, please take a look at our Year-round Options Guide for other safe disposal options.   Please note that there may be a charge for disposing of items that are normally accepted for free at the annual event.  We do recommend calling the business first.
