The volume contains, in ascending submission number order, 'status reports' (i.e., preliminary evaluations) prepared by staff of the Office of Toxic Substances in EPA's Office of Pesticides and Toxic substances for initial submissions received by EPA from chemical manufacturers, importers, processors and distributors from January 1, 1985 to December 31, 1986 under Section 8(e), the 'substantial risk' information reporting provision of the Toxic Substances Control Act (TSCA). The status reports contained in this compendium reflect only the initial phase of the Agency's evaluation process for the submitted information. The TSCA Section 8(e) status reports volume has been published by the Agency for two reasons. First, a volume of Section 8(e) status reports with appropriate indices will make the submitted information more accessible. Second, this volume may, by providing specific examples of submitted information and EPA's preliminary evaluation of that information, help those persons subject to Section 8(e) understand better the types of information that should be submitted to EPA under this mandatory reporting provision of TSCA.
