Hazardous Materials Program.

Household Hazardous Materials Regional Collection Center is Open for the Season

The Household Hazardous Materials Regional Collection Center (RCC) is a permanent drop-off facility co-located with the DMASWA Landfill.  It is designed as a seasonal drop-off location, open April through October, for household hazardous materials (HHM).  Household hazardous materials consist of oil-based paints, wood stains and finishes, lawn and garden chemicals, household cleaning chemicals, and other items that are potentially harmful to Iowa’s ground and surface waters.  

Residents are encouraged to utilize the materials as they are intended to be used and store them as directed on their containers. Any latex items can be dried out and placed with other trash. If materials need to be disposed of, they should be placed in plastic containers for transport to avoid spills, and brought to the RCC located at the Landfill facility.  

This program is supported through landfill tonnage fees and is a service provided to the residents of Dubuque and Delaware counties at no charge. Collection hours for the facility are 7:30 am – 3:30 pm, Monday through Saturday. Please stop at the scale house when you arrive to recieve directions.
