The Toxic Substances Control Act (TSCA) requires EPA to publish a list of new chemical submissions received by the Agency under TSCA Section 5. The list of submissions received includes premanufacture notices (PMNs), Significant New Use Notices (SNUNs), Microbial Commercial Activity Notices (MCANs), Test Market Exemption Applications (TMEAs), Notices of Commencement of Manufacture or Import (NOCs), and test information submitted under section 5.

EPA is making this list of new chemical submissions received available in one place on our website to increase transparency and make information on new chemicals easier to find. This provides an alternative to searching individual Federal Register notices and dockets on www.regulations.gov. The links below provide a listing of the following types of new chemical submissions received. These lists will be updated on a regular basis.

• PMN/SNUN/MCAN/TMEA Submissions Received
• Notices of Commencement Received
• TSCA Section 5 Test Information Received
