Updating an issue we have been tracking, the California Office of Environmental Health Hazard Assessment finalized the No Significant Risk Level for DINP of 146 µg/day. The NSRL will got into effect April 1, 2016.

Once in effect, this will be the level of exposure at which a warning is required for DINP. This will remove one of the significant, and expensive, hurdles to defending against a Proposition 65 claim, as a company will not need to develop an NSRL as part of its case.

From a planning perspective, it also allows manufacturers to assess their products and, if necessary, lower the amount of DINP in the product that may result in an exposure.

Private plaintiff have issued more than 230 Prop 65 60-day notices since warnings were required for significant exposures to DINP at the end of 2014.
