The U.S. Environmental Protection Agency intends to negotiate a contract with Chemical Abstract Services (CAS) of the American Chemical Society to provide chemical expertise support in assisting the Office of Pollution Prevention and Toxics (OPPT) in making chemical identity determinations which are required to support the implementation of the Premanufacture Notification review mandated under Section 5(a) of TSCA, as well as the continuing development/update of the TSCA Chemical Substances Inventory. The authority for other than full and open competition is 41 U.S.C. 253(c)(1). The period of performance is one year with four one year options. It is anticipated that the contract will be a fixed rate contract. Under the proposed contract, the contractor shall be responsible for providing chemical expertise in assisting EPA in making chemical identity determinations of the commercial chemicals. Specifically, the contractor shall uniquely identify each chemical with the most correct and unambiguous Chemical Abstracts Index Name, and assign, whenever appropriate, a Chemical Abstract Service (CAS) Registry Number, as well as other appropriate chemical data including chemical structures, chemical synonyms, and molecular formula, in accordance with EPA's established policies and practices of how similar substances are represented on the TSCA Inventory. The contractor shall assist EPA in its review of new chemicals by determining whether the substance under review is chemically identical to a chemical already listed on the TSCA Chemical Inventory. The contractor shall also be responsible for the continued development and maintenance of the Inventory by adding to it newly manufactured chemicals which have been approved by EPA under Premanufacture Notification review and be correcting any nomenclature discrepancies when they are identified.
