California’s Office of Environmental Health Hazard Assessment (OEHHA) has approved the adoption of the “Lead Agency Website” regulation (Section 25205). The regulation requires OEHHA to create a website providing information to the public on exposure to chemicals that require warning disclosure under Proposition 65. The regulation has been very controversial with industry, including several trade groups.

Under the Regulation, which takes effect on 1 April, 2016, a manufacturer, producer, distributor or importer of a product giving a Prop 65 warning will have to provide, within 90 days of the agency’s request:

• the name of the listed chemical(s) for which warning is given;
• the location of the chemical(s) in products that require warning under Prop 65;
• the concentration of the chemical(s) in these final products;
• anticipated routes or pathways of exposure to listed chemicals; and
• estimated levels of exposure to the chemical(s).

The regulation and additional information is available on the OEHHA website.
