The Office of Environmental Hazard Assessment (OEHHA) has recently approved the petition for rulemaking submitted by Californians for Pesticide Reform (CPR) to develop a proposition 65’s No Significant Risk Level (NSRL) for 1,3 -Dichloropropene (1,3-D). The chemical substance 1,3 -D was added to the list in 1989 under the Safe Drinking Water and Toxic Enforcement Act of 1986 (currently Prop-65). The chemical was added to the list to cause cancer in human beings.
The OEHHA has been intended to develop a no significant risk level for the 1,3 –D & so currently it has been requesting scientific information which can be used for the development of NSRL for this substance. NSRL is nothing but a “safe harbor level” at which any chemical substance should possess no significant risk to the environment. The companies are not needed to provide warnings when the substance exposure is below a significant level. But when the exposure level exceeds the companies are liable under Prop-65 even though they can demonstrate no significant risk for cancer through other means.
The OEHHA has informed that any written submission in response to theirs request on the website before 27th April 2021 will be considered & the opportunity for public comments will proceed once the OEHHA initiates the formal rule-making process on NSRL for the 1,3 –Dichloropropene substance.
