You can drop off your household hazardous waste for free tomorrow (November 19) from noon to 7pm at the Wright United Church of Christ on W. Franklin Street. All Household Hazardous Waste mobile collection sites are open from 12 p.m. to 7 p.m. one day per month throughout the year. Note: Do NOT leave items at a site when a collection vehicle is not present. Leaving toxic chemicals unattended at a collection site creates hazardous conditions and is a violation of Boise City Code. The program does not accept explosives, radioactive materials, biomedical waste or tires.
