On April 16, 2007, the U.S. Environmental Protection Agency (EPA) announced that, due to a technical problem, it is unable to verify receipt of contact information from anyone who subscribed to the e-mail notification list on the Office of Pollution Prevention and Toxics (OPPT) Nanotechnology web page from October 18 to November 1, 2006, and again from January 18 to January 23, 2007. According to EPA, it has corrected the problem and is now compiling a list of stakeholders to contact as the Nanoscale Materials Stewardship Program moves forward. EPA requests that anyone who subscribed to the e-mail notification during these periods do so again.
