### Subject: Follow-up to fax transmission of4/13/12 (ePMA

### removal ofCBI claims regarding identified studies) 

### Dear Mr. Merritt: This is sent to you pursuant our conversation ofseveral minutes ago. In Larry Robinson's fax of April 13th 

### while there is a waiver ofconfidential business information (CBI) claims in the identified studies there is a an assertion ofcopyright protections and some additional text that provides in part ... "Reproduction, reference, summarization, retransmission or other use ofthis copyrighted document...including electronic transmission, using the internet oremail....is strictly prohibited...." While we understand the basis for the copyright protections, we have a concern that the language in the fax might be interpreted to mean that ePMA is asserting that the studies submitted perthe TSCA activity are not to be made available in an Agency e-docket (electronic docket) or be included in EPA websites among the collection ofTSCA health and safety studies. We are thinking that the identified limitations noted in the fax are not intended to apply to EPA's normal procedures for the handling ofnon-CBI materials submitted by entities subject to TSCA regulations (including the posting ofsuch materials on government websites) and submitted by such entities in order to comply with a TSCA requirement, but are rather intended to limit entities outside the government from the unauthorized use or appropriation ofthe studies. Can you please confirm CPMA's intent? Many thanks.
