OEHHA Adopts NSRL for Vinylidene Chloride


OEHHA has approved a NSRL of 0.88 micrograms per day for Vinylidene Chloride, which is used to make Saran wrap.

California’s Office of Environmental Health Hazard Assessment (OEHHA) on May 9 received approval from the state Office of Administrative Law to adopt an amendment to Title 27, California Code of Regulations, section 25705, No Significant Risk Level (NSRL) for the chemical vinylidene chloride.
The agency announced the adoption of the new NSRL on May 17.
The regulation establishes a No Significant Risk Level of 0.88 micrograms per day for vinylidene chloride for purposes of Proposition 65. A No Significant Risk Level is the is the level at which a chemical would have no observable effect assuming exposure at 1,000 times that level.
Vinylidene chloride, also known as 1,1-Dichloroethylene (CAS No. 75-35-4) was listed as a Proposition 65 carcinogen on December 29, 2017. The chemical was listed by the Labor Code listing mechanism with little resistance from industry or individuals.
According to the U.S Environmental Protection Agency, Vinylidene chloride is used as an intermediate for organic chemical synthesis. Vinylidene chloride is also used in the production of polyvinylidene chloride co-polymers such as SARAN and VELON wraps, and for fiber and carpet backing and in piping, coating for steel pipes, and adhesive applications. While the chemical’s uses are diverse, potential enforcement actions for this chemical will most likely focus on its use as a food contact material.
OEHHA listed vinylidene chloride as a chemical known to the state of Calfiornia to cause cancer for purposes of Proposition 65 on December 29, 2017. Previously, on September 22, 2017, OEHHA issued a Notice of Proposed Rulemaking to adopt its’ proposed amendment to Section 25705, Specific Regulatory Levels Posing No Significant Risk, identifying an NSRL of 0.88 micrograms per day (μg/day) for vinylidene chloride under Title 27, California Code of Regulations, section 25705(b)
The regulation for the NSRL will take effect on July 1, 2018.
