Ecology is developing a
Chemical Action Plan (CAP)
for polychlorinated biphenyls (PCBs).
What are Persistent, Bioaccumulative Toxics (PBTs)?The goal of Ecology's PBT initiative is to reduce and phase-out the use, release, and exposure to PBTs in Washington in order to to reduce and eliminate threats to human health and the environment.
Persistent, bioaccumulative toxics (PBTs) are a distinct group of chemicals that threaten the health of people and the environment. Examples of PBTs include methylmercury, PCBs, DDT and dioxin. These types of toxic chemicals are considered the "worst of the worst" and raise special challenges for our society and the environment because:
How is Ecology addressing PBTs?
Ecology published our Strategy to Reduce PBTs in December 2000. After working with an advisory committee and getting input from the public, the PBT Rule was published in January 2006. The PBT rule includes PBT criteria and a list of PBTs that meet these criteria, as well as procedures to periodically update the list. The focus of our work on PBTs is preparing and implementing Chemical Action Plans (CAPs). The PBT rule describes the parts of a CAP, how CAPs are developed, and how PBTs are chosen for a CAP.
