Confidential Business Information under TSCA

TSCA CBI Training - Document Management

TSCA CBI Document Management

Where should TSCA CBI be sent? Submitters should be directed to send incoming TSCA CBI to a DCO only. CBI sent between organizations must be sent from one DCO to another DCO. CBI sent to OPPT (e.g., by US mail, courier, or fax transmission) may be addressed to either an EPA or contractor DCO, but preferably to the Confidential Business Information Center (CBIC).
