What is Clean Sweep?
Clark County’s Agricultural & Household Clean Sweep program will give farmers and residents an opportunity to dispose of hazardous chemicals to help protect our surface and groundwater.
Why Is the Clean Sweep Necessary?
The average U.S. citizen generates somewhere between 6 and 15 pounds of household hazardous waste annually. Applying those rates to Clark County’s 34,774 residents, our county generates between 208,644 to 521,610 pounds of household hazardous waste each year.
How is Clean Sweep Funded?
Funding for Clean Sweep is provided through Clark County Board of Supervisors budgeting and grants from the Department of Ag, Trade & Consumer Protection (DATCP) and other state, federal or private business grants.
Leadership for the Clean Sweep effort is through the following Clark County Departments:
- UW-Extension Clark County
- Emergency Management
- Forestry and Parks
- Highway
- Land Conservation
- Public Health
- Sheriff’s Department
Chemical Waste Disposal
What are waste chemicals?
Chemicals become waste when they are no longer wanted or when they can no longer be used. Waste pesticides include banned products, products damaged during storage or by contamination, outdated or surplus amounts of products, and products which are no longer in use because they have been replaced by more effective products.
How Is Hazardous Waste Identified?
Hazardous waste can usually be identified by product labels which contain words like: caution, warning, danger, poison, toxic, ignitable or flammable, acid, corrosive, or reactive.
How much hazardous waste can I bring?
To ensure fair access and the widest possible participation by all Clark County residents, the following limits have been established:
- Agricultural: Farmers and farm households will be allowed to bring a total of 200 pounds of hazardous waste. Any amounts above 200 pounds will be charged $2.00/lb. DO NOT MIX LIQUIDS and/or SOLIDS.
