Companies may need to carefully consider practical business concerns to comply with the updated Prop 65 regulations, effective August 30.

By Michael G. Romey, Lucas I. Quass, and James A. Erselius

New regulations governing the implementation of the Safe Drinking Water and Toxic Enforcement Act of 1986 (Prop 65) will go into effect on August 30, 2018 that apply to products manufactured after the operative date of August 30, 2018. The new regulations update the content of the Prop 65 warning label that appears on products, in addition to other substantive changes.

Below is one example of how the new warning may look; however, the exact content will depend on the specifics of the exposure in question.

Compliance with the updated Prop 65 regulations often requires companies to review the chemical makeup of their products and evaluate relationships within the chain of commerce, as well as to work with upstream and downstream entities to ensure that adequate measures are in place to provide a chemical specific warning that meets the new safe harbor language. For some companies, this process is fairly straightforward; for others, it is more complex and requires careful consideration of practical business concerns.
