Developments in State Chemicals Policy:

Identifying and Regulating Priority Chemicals

 

Background

Chemicals are emitted by a wide array of products used indoors—from buildings materials and furnishings to household products and office equipment. According to the U.S. Environmental Protection Agency (EPA), concentrations of many volatile organic compounds (VOCs) “are consistently higher indoors (up to ten times higher) than outdoors." EPA, Volatile Organic Compounds' Impact on Indoor Air Quality. In its 2005 report Indoor Air Pollution in California, the California Air Resources Board (ARB) discussed a wide range of adverse health impacts associated with indoor chemical exposures, including irritant effects, allergic reactions, respiratory disease, developmental effects, organ damage, and cancer. At the same time, the report noted that “[s]cientific study has only touched the ‘tip of the iceberg’ in understanding all VOCs in indoor air.”

The principal federal law governing chemicals management in the U.S. is the Toxic Substances Control Act (TSCA), implemented by EPA. To date, the agency has been able to require testing on just over 200 of the 84,000 chemicals listed on the TSCA Inventory and has issued rules to ban or limit only five chemicals deemed to pose an unreasonable risk. In June 2016, the President signed comprehensive legislation to reform TSCA. The legislation includes a variety of significant provisions that will change EPA’s implementation of TSCA and alter the states’ role in chemical regulation.

State Laws
In recent years, a considerable number of states have enacted laws or regulations restricting the use of specific chemicals in products, including policies addressing formaldehyde, PBDEs (flame retardants), phthalates, and bisphenol A.  This Policy Brief focuses on state laws that have established broader policy frameworks for managing chemical risks by requiring the identification and prioritization of chemicals of concern. Some of the laws also establish provisions for: considering safer alternatives to priority chemicals; requiring manufacturer reporting on the use of priority chemicals; banning or restricting the use of particular priority chemicals; and promoting information exchange and research on priority chemicals. The laws in six states—Connecticut, Maine, New York, Oregon, Washington and Vermont—address primarily chemicals in children’s products. California’s law is being implemented as part of a broad Green Chemistry initiative. Watch for updates to this page as these laws are implemented and new state laws are enacted.
