Quality Assurance Project Plan Phthalates and Metals in Tier 3 Children’s Products April 2013 Publication No. 13-03-108 Publication Information Each study conducted by the Washington State Department of Ecology (Ecology) must have an approved Quality Assurance Project Plan. The plan describes the objectives of the study and the procedures to be followed to achieve those objectives. After completing the study, Ecology will post the final report of the study to the Internet. This Quality Assurance Project Plan is available on Ecology’s website at https://fortress.wa.gov/ecy/publications/SummaryPages/1303108.html Data for this project will be available upon request, provided it is not enforcement sensitive.

The CSPA legislation limits the amount of phthalates, lead, and cadmium allowed in children’s products sold in Washington and also requires manufacturers to report to Ecology if their products contain certain chemicals. Ecology will test children’s products for a subset of these chemicals – eight phthalates and seven metals – in 2013. Ecology will collect approximately 200 children’s products in the Tier 3 category of the CSPA Reporting Rule, with a focus on toys intended for children ages 3 to 12 years old. Products will be pre-screened for metals with an X-ray fluorescence (XRF) analyzer. Up to 35 product samples will be sent to a laboratory for metals analysis based on XRF measurements, and 40 samples will be forwarded to a laboratory for phthalates analysis. A final report summarizing findings is anticipated to be published in December 2013. Page 4 Background Washington State passed the Children’s Safe Products Act (CSPA) in 20081. Part of this law prohibited the sale of a children’s product, or product component, containing phthalates (greater than 1,000 ppm, individually or in combination), lead (greater than 90 ppm), or cadmium (greater than 40 ppm). Another part of this law required the Departments of Ecology (Ecology) and Health (DOH) to develop a list of chemicals of high concern for children (CHCC). Beginning August 2012, manufacturers must report to Ecology if a product contains a chemical from this list. For more information on the CSPA legislation, visit http://www.ecy.wa.gov/programs/swfa/cspa/. The CSPA Reporting Rule requires manufacturers to report on CHCCs in products on a phased- in schedule according to the type of product and size of manufacturer2. Manufacturers are separated into size categories by gross annual sales of children’s products. The largest manufacturers started reporting in August 2012 on Tier 1 products. Reporting for Tier 2 products began in February 2013. Tier 3 products are next in line to be reported (August 2013) by the largest manufacturers. Tier 4 products will not be reported on, except by amendment of the reporting
