King County LHWMP is a regional program of local governments working together to protect public health and environmental quality by reducing the threat posed by the production, use, storage, and disposal of hazardous materials. We offer services to help residents and businesses reduce, safely handle, and properly dispose of hazardous materials and wastes.

King County LHWMP also provided funding in 2008 that helped facilitate the creation, development, and launch of IPMopedia.

King County LHWMP runs The EnviroStars Program that certifies businesses for reducing, recycling, and properly managing hazardous waste. The program was created in King County, Washington, in 1995 and has expanded to include many additional counties in the Puget Sound region.

Use the resource to find companies in Puget Sound that are making strides to protect the environment. This is a great place to find a certified landscaper that can help you design and maintain a healthy, green garden.
