[Note: The EPA Draft Exposure Summaries reflect the Agency's current thinking, and are working drafts. These documents and the accompanying Example Exposure Assessment and Example Format are intended to provide assistance to the sponsors in meeting their commitments under VCCEP. The formats are not intended to be prescriptive, but rather, to present a suggested flow of information, and not all elements may be appropriate for every chemical. These documents do not necessarily reflect what the Peer Consultation process will determine to be adequate in the pilot VCCEP as each chemical will be assessed and evaluated on a case by case basis.]
