California's Office of Environmental Health Hazard Assessment (OEHHA) adopted a temporary emergency regulation on April 18, 2016, which implemented warning label method and content provisions specifically for exposures to BPA from canned and bottled foods and beverages sold at retail level. Effective May 11, 2016, BPA exposure warnings must be affixed to the product container or, alternatively, posted on a sign at each point-of-sale (cash register, check-out line) in the retail location; in addition, the emergency regulation stipulates strict warning language requirements that specify the chemical of interest and its health endpoint of concern ("harm to the female reproductive system"). The provisions in the emergency regulation are in effect until October 17, 2016.
On July 29, 2016, OEHHA issued a notice of proposed rulemaking to continue the emergency BPA warning regulation provisions until December 30, 2017. However, this new regulation limits the scope of the point-of-sale warning provisions. To utilize point-of-sale warning signs rather than individual product labels, food and beverage companies that intentionally use BPA must submit the following product identifying information in a "searchable, electronic format" to OEHHA:
• Brand name
• Product description, including FDA product category
• Universal Product Code or other identifying designation
• Where applicable, the last expiration or 'use by' date for the product(s) where BPA was intentionally used
Once submitted, OEHHA will publish the above information on its website, so that consumers can learn where BPA is intentionally used in food and beverage containers. A public hearing on the proposed regulatory amendment is scheduled for 10:00 a.m. on September 12, 2016 in the Sierra Hearing Room at the CalEPA Headquarters building 1001 I Street in Sacramento. The hearing will also be webcast.

The United States Environmental Protection Agency's (USEPA) Regional Screening tables were recently updated. These Regional Screening tables are typically revised and posted twice per year. The Regional Screening Levels (RSLs) presented in these tables are risk-based concentrations that are derived from equations that take into account exposure assumptions, in addition to USEPA toxicity data. RSLs are used in the initial screening of contaminated sites, including Superfund sites, such that particular areas, contaminants, and conditions at the sites are identified and receive further attention from USEPA. The screening levels are considered to be protective for human health over a lifetime and do not consider any ecological risk endpoints.
As part of the update, the RSLs for several chemicals were adjusted to reflect changes in their toxicity values and chemical-specific parameters. Specifically, the inhalation unit risk for dibromochloromethane was deleted when it was withdrawn by Cal EPA. Additionally, toxicity values for nine chemicals were added, because these chemicals have new Provisional Peer Reviewed Toxicity Values (PPRTV), 11 chemicals were changed from old Health Effects Assessment Summary Table (HEAST) toxicity values to updated PPRTV toxicity values, common chemical names for 24 pesticides were replaced with their technical names, and melting point values were added to the parameter table for all chemicals. Furthermore, all of the physico-chemical parameter values were revised to be consistent with those used to determine the USEPA Vapor Intrusion Screening Levels (VISLs).
