From the office of the Federal Register:
The US EPA has published 19 premanufacture notices (PMNs) and ten notices of commencement (NOCs) for new chemicals. Section 5 of the Toxic Substances Control Act (TSCA) requires any person who intends to manufacture (defined by statute to include import) a new chemical (i.e., a chemical not on the TSCA Chemical Substances Inventory (TSCA Inventory)) to notify EPA and comply with the statutory provisions pertaining to the manufacture of new chemicals. Under TSCA sections 5(d)(2) and 5(d)(3), EPA is required to publish in the Federal Register a notice of receipt of a premanufacture notice (PMN) or an application for a test marketing exemption (TME), and to publish in the Federal Register periodic status reports on the new chemicals under review and the receipt of notices of commencement (NOC) to manufacture those chemicals. This document, which covers the period from February 20, 2012 to February 29, 2012, and provides the required notice and status report, consists of the PMNs pending or expired, and the NOC to manufacture a new chemical that the Agency has received under TSCA section 5 during this time period.
