MoreThe EPA proposed to modify a SNUR that might have made a big
deal over a small (or nonexistent) danger concerning a chemical used in UV
technology. The agency is proposing to amend the significant new use rule
(SNUR) for 2-Propen-1-one, 1-(4-morpholinyl)- (CAS No. 5117-12-4) to allow
certain uses without requiring a significant new use notice (SNUN).
The regulation at issue was originally passed in January 2000. The agency is now proposing to modify the significant new use and recordkeeping requirements for the chemical substance 2-Propen-1-one, 1-(4-morpholinyl)- (CAS No. 5117-12-4). The PMN substance will be used as a diluent for ultraviolet (UV) and electron beam curable resin for coatings, inks and curable adhesives. The SNUR would have made the chemical okay to use except as a spray or aerosol, but the agency's later tests suggest that touching the chemical doesn't have any adverse effects.
The EPA has determined that the results of the combined repeated dose toxicity with the reproductive/developmental toxicity screening test would help further characterize the human health effects of the PMN substance. The modified 5(e) consent order does not require submission of the aforementioned information at any specified time or production volume. However, the order's restrictions on manufacturing, import, processing, distribution in commerce, use and disposal of the PMN substance will remain in effect until the order is modified or revoked by the EPA based on submission of that or other relevant information.
