Household Hazardous Waste Program

The Household Hazardous Waste (HHW) program provides SISW the chance to divert household hazardous waste from directly entering the landfill. By running the program in accordance with policy, we reduce the potential of health hazards by processing the waste prior to final disposal in the landfill. We positively impact the environment by recycling used oil and antifreeze accepted in the program. Participation, acceptance and quantities are limited so employee awareness is crucial for a successful HHW program.

The HHW program has expanded over the years. When the program was implemented, it was limited to used oil, antifreeze, flammable and combustible liquids and rechargeable batteries. The HHW program has expanded by including corrosive waste; pesticides, herbicides and fertilizers; small amounts of mercury and the capture of freon. The HHW program has the ability to divert abnormal waste out of the municipal solid waste (MSW) stream and dispose of it properly, if needed.

Program Use Intentions

The SISW district's HHW program is intended to be used by non-commercial citizens living in the counties of the district. All hazardous waste generated by households during their normal course of activities is exempt from hazardous waste regulation. HHW can still be a detrimental threat to the environment as well as human health.

Accumulated quantities of hazardous waste from businesses will not be accepted as part of the district’s HHW program. Businesses that qualify as a Conditionally Exempt Small Quantities Generator (CESQG), which produce less than 25 gallons or 220 pounds of hazardous waste per month, should contact Josh Bartlome at Milner Butte Landfill to discuss disposal options.
