Publication Summary

This draft "Multiyear PBT CAP Schedule" is the Washington State Department of Ecology′s (Ecology) proposed schedule for developing chemical actions plans (CAPs) as part of implementing the agency′s recently adopted "PBT rule" (WAC 173-333). The PBT rule is a procedural rule, which establishes Ecology′s process and procedures to address the subject of persistent bioaccumulative toxic substances and helps Ecology set internal priorities in addressing PBTs. The PBT rule is part of the state′s efforts to protect the people and environment of Washington by reducing exposure to these chemicals.

This draft document lays out the planned schedule for the next three calendar years and provides the rationale for, and supporting documentation on, how Ecology arrived at the prioritization of chemicals for action.

Based on the available data for the evaluation factors, and using best professional judgment, the following chemicals will be the focus of the next three CAPs developed by Ecology and Health, on the schedule indicated:

PBT Chemical CAP Development Schedule

• Lead:  Nov. 2006 – March 2008
• Polycyclic aromatic hydrocarbons (PAHs): Sept. 2007 – March 2009
• Perfluorooctane sulfonates (PFOS): Sept. 2008 – March 2010

Ecology will review and, as appropriate, update the multiyear schedule for chemical action plans at least once every three years (PBT rule, WAC 173-333-410(6)). The current schedule, and all subsequent ones, will be open for a 60 day public comment period before finalizing.
