The California Office of Environmental Health Hazard Assessment’s (OEHHA) has extended the comment period on a proposed amendment to Section 25821(a) of Title 27 of the California Code of Regulations, which addresses calculating the exposure level to chemicals listed under Proposition 65 as reproductive toxicants.

The California Office of Environmental Health Hazard Assessment (OEHHA) recently posted a fact sheet on styrene on its Proposition 65 warning website. That fact sheet includes a confusing recommendation concerning polystyrene. The Proposition 65 warnings website was a rulemaking initiative undertaken by OEHHA to increase the level of detail provided about chemicals on the Proposition 65 lists.

California’s Office of Environmental Health Hazard Assessment (OEHHA) has proposed amending the Proposition 65 Article 6 Clear and Reasonable Warning requirements, on the responsibility to provide consumer product exposure warnings.

The California Office of Environmental Health Hazard Assessment’s (OEHHA) has extended the comment period on its proposal to amend Section 25821(a) and (c) of the Proposition 65 regulations, which dictate how to calculate exposure to reproductive toxicants for average consumers. Comments are now due by December 3, 2018.

Comments on the California Office of Environmental Health Hazard Assessment’s (OEHHA) proposal to amend Section 25821(a) and (c) of the Proposition 65 regulations, which dictate how to calculate exposure to reproductive toxicants for average consumers, are due by November 26, 2018.  The comment period was extended after OEHHA scheduled a

California’s Office of Environmental Health Hazard Assessment (OEHHA) proposed two Maximum Allowable Dose Levels (MADLs) for n-hexane under Proposition 65, one for oral exposure to n-hexane, and one for inhalation exposure. The proposed oral MADL for n-hexane is 28,000 micrograms per day, and the proposed inhalation MADL for n-hexane is 20,000 micrograms per day.

A California appeals court reversed a trial court decision that would have required a Proposition 65 warning on breakfast cereals.  Proposition 65, or the Safe Drinking Water and Toxic Enforcement Act of 1986, prohibits a company from knowingly exposing any individual to a listed chemical without first providing a "clear and reasonable warning" to such individual.

As proposed, the California Office of Administrative Law approved a No Significant Risk Level (NSRL) for vinylidene chloride of 0.88 micrograms (µg) per day under the state’s Safe Drinking Water and Toxic Enforcement Act of 1986, also known as Proposition 65. Vinylidene chloride was listed as a carcinogen under Proposition 65 on December 29, 2017, and California’s Office of Environmental Health Hazard Assessment (OEHHA) proposed the NSRL on September 22, 2017. Comments on the proposed NSRL were accepted through November 6, 2017.
