EPA announced they will require registration of products containing nanoscale silver that are designed to control microbes. The agency indicated it would not immediately act against unregistered products, such as socks, now sold in the U.S. http://1.usa.gov/1GEPZy9

EPA separately proposed a one-time requirement for makers of nanoscale commercial chemicals currently on the market to notify the agency about all available health and safety data for their products. Under this proposal, these manufacturers would also have to submit production volume and processing, use, exposure, and release information to EPA. http://www.epa.gov/oppt/nano/nano-fact-sheet.html

The ELAP program transitioned from the California Department of Public Health to the California State Water Resources Control Board in July 2014, and an Expert Review Panel has been formed to undertake a comprehensive review of the accreditation process. Presentations from a meeting held March 17-19 have been posted.
