Specifically, in response to its authorities and stakeholder requests, NIOSH is pursuing a nanotechnology research program including a strategic mix of laboratory studies, field studies, and support for extramural studies.  To assist in these activities, NIOSH is seeking information on nano-substances and other materials in the possession of EPA.

EPA is issuing this notice to inform all submitters of information under all sections of TSCA that the Agency will be providing NIOSH access to these CBI materials on a need-to-know basis only.  All access to TSCA CBI under this arrangement will take place at EPA Headquarters and the NIOSH Headquarters located at 4676 Columbia Parkway, Cincinnati, OH 45226.

Clearance for access to TSCA  CBI under this arrangement may continue until August 1, 2016.
