  1. Chemical Selection and Prioritization for Washington’s Children’s Safe Product Act (CSPA) Alex Stone Chemist, WA Dept. of Ecology EPA Prioritization Workshop April 6-7, 2010

  2. CSPA Implementation Three Phases • Identification of Chemicals of High Concern to Children (CHCCs) • Prioritization of CHCCs • Final review and determination of CHCCs to be placed into regulation

  3. Phase 1 • Identify High Priority Chemicals (HPC) • Identify Chemicals in Potential Exposure Sources • Identify Chemicals of High Concern to Children (CHCCs), i. e. chemicals that are: • An HPC and • Found in at least one of the potential exposure pathways

  4. ‘High Priority Chemicals’ (HPCs): (From legislation) • Section 2: Definitions • ‘High priority chemical’ as identified by: • State agency • Federal agency • Accredited research university • Other scientific evidence deemed authoritative by Ecology • One or more of the following criteria: • Developmental toxin • Cause: • Cancer • Genetic damage • Reproductive harm • Endocrine disruptor • Damage: • Nervous system • Immune system • Organs • Other systemic toxicity • PBT • vPvB (very persistent & very bioaccumulative) HPCs

  5. HPC Sources:

  6. From HPCs, identify ‘chemicals of high concern to children (CHCCs): (From legislation) Exposure Lists: Section 4: Identifying high priority chemicals of high concern for children after considering a child’s or developing fetus’s potential for exposure to each chemical. One or more of the following criteria: Chemicals found in biomonitoring studies: • Humans • Umbilical cord blood • Breast milk • Urine • Other bodily tissues or fluids • Chemicals found in: • Household dust • Indoor air • Drinking water • Elsewhere in the home • Added or present in consumer product used or present in the home Exposure

  7. Exposure Chemical Selection • Generated data in 4 Biomonitoring & potential exposure areas • Biomonitoring • NHANES & Danish Birth Cohort • Journal Articles • Indoor Air & Dust • CA Air Resources Board • Journal Articles • Drinking Water • EPA drinking water standards • Journal Articles • Products • Primarily Danish and Dutch consumer product studies

  8. Exposure Chemical Results

  9. Chemicals removed before further prioritization: 476 178

  10. Phase 2 • Governor’s veto message directed Ecology to place greater emphasis upon chemicals found in children’s products • Prioritized products based upon 3 toxicity criteria of most importance to children and presence in children’s products • Used a ‘weight-of-evidence’ approach

  11. Phase 2 Toxicity criteria • Developmental or reproductive toxicity • Endocrine disruption • Carcinogenicity Exposure criteria • Presence in Children’s products • Exposure potential from those products • Known exposure in general population Created ‘Score Card’ to evaluate CHCCs • Filled out score cards on 178 potential CHCCs

  12. Phase 2 (cont.) • Add WA PBTs back onto list • Reduced 178 to 65 potential CHCCs

  13. Phase 3 Final review of 65 CHCCs to determine those placed into regulation Four components part of final determination: • Final toxicity and exposure review • Determination of a reasonable analytical method • Determination of a reporting level • Overall policy review In the meantime conducting Pilot Rule

  14. Pilot Rule • Create draft rule • Work with regulated community and interested parties to evaluate effectiveness of proposed rule • Based upon input, propose final rule which will contain final list of CHCCs • Undergo formal public comment process • Once finalized, any product sold or manufactured in WA must report to Ecology presence of chemical in product and certain additional information
