The Office of Environmental Health Hazard Assessment shall, by June 1, 1987, develop a list of those art or craft materials which cannot be purchased or ordered for use in kindergarten and in grades 1 to 6, inclusive, and a list of materials which, while not currently sold or manufactured, may be reasonably suspected to still exist at some schools.  In developing the lists, the office shall consult with manufacturers of art supplies, artists' groups, health organizations, and toxicologists as the office determines to be appropriate.  The office shall periodically update the lists as it determines to be appropriate.

The Superintendent of Public Instruction shall distribute the lists to all school districts and the governing authorities of all private schools in California, and shall make the lists available to preschools, childcare centers, and other businesses and organizations which involve children in the use of art or craft materials.

The superintendent shall inform school districts and governing authorities of all private schools of the requirements of this article, and shall encourage school districts and the governing authorities of all private schools to dispose of art or craft material which may contain human carcinogens, potential human carcinogens, or chronically toxic substances, but which is not affected by this article.
