December 2017 OEHHA finalized minor amendments to the new Labeling requirements. Most of the changes are not substantive and were meant to clarify the existing regulations.

Subsequent to the adoption of the August 2016 amendments to the Article 6 Clear and
Reasonable Warnings regulations, the Office of Environmental Health Hazard
Assessment (OEHHA) received numerous inquiries related to the interpretation and
application of several provisions of the amended regulations. OEHHA therefore
determined that clarification of certain provisions of the new regulations would be
beneficial to the regulated community. The proposed amendments are intended to
further clarify the guidance OEHHA provides to businesses to better understand how tocomply with the warning requirements.
