Is there a more explicit list of what wastes are household-hazardous wastes (HHW)? *
Yes. Under Chapter 70.105 RCW Ecology is required to prepare guidelines that include a list of substances identified as hazardous household substances. This list is contained in Appendix F of the Guidelines for Development and Updating Local Hazardous Waste Plans, publication #10-07-006.
Hazardous household substances that become wastes are commonly called household hazardous waste (HHW). There are seven groups of these hazardous substances listed in the local hazardous waste plan guidelines. The seven groups and substances in each group are as follows:
Local governments can add additional substances to this list for any household products which may pose a public health or environmental risk.
* Note: The answers provided to Frequently Asked Questions are guidance for implementing WAC 173-350-360. Following this guidance is not a requirement of operation or design for MRW facilities, as facilities may meet regulatory requirements through other means. Local Health Departments should be consulted to determine what will be sufficient to meet the regulatory standards.
