The US EPA received 34 pre-manufacture notices (PMNs) in July and 41 amendments to past PMNs, according to a 22 October Federal Register notice. The manufacturer's identity was withheld on 48 of the 75 as confidential business information (CBI).
A significant new use notice (Snun) for functionalised multiwall carbon nanotubes as an anti-corrosion or strengthening additive in epoxy compounds for coatings, paints and composites was included in the announcement. The Snun is an amendment to a previously submitted notice.
The agency also received in July test data in support of 13 previously submitted PMNs; 19 notices of commencement (NOCs); and an application for a test marketing exemption (TME).
Section 5 of TSCA requires notification when any person intends to manufacture or import a chemical substance for a non-exempt commercial purpose, either for the first time (PMN) or for a 'significant new use', for substances subject to a significant new use rule (Snur). Submitters must provide the EPA with the appropriate information before initiating the activity; the agency reviews those notices, evaluates risk and takes appropriate action.
Under 2016 updates to TSCA, the EPA must publish a list of these submissions monthly.
