Lawyers say a U.S. Environmental Protection Agency drive to collect scientific data from companies using nanotechnology materials has their clients concerned about confidentiality and possible disclosure of unwitting violations of federal law.
Also, attorneys note that a weak response to the EPA program � which is voluntary � could open the door to a patchwork of confusing local laws that could vex companies across the nation. In fact, some local governments are already launching their own ordinances seeking information on the use of “nanomaterials.”
