EPA issued final significant new use rules (SNURs) in the Federal Register of September 2, 2014 for 36 chemical substances which were the subject of premanufacture notices (PMNs). For the chemical substance identified generically as diisocyanate terminated polycarbodiimide (PMN P-04-640), EPA inadvertently omitted the de minimus exemption from the worker protection requirements. Also, for the chemical substance identified generically as hexanedioic acid, polymer with .alpha.-hydro-.omega.- hydroxypoly[oxy(methyl-1,2- ethanediyl)],1,1'-methylenebis[4-isocyanatobenzene], dihydroxydialkyl ether and dialkanol ether (PMN P-11-311) a typographical error in the PMN number has been identified. The amendments in this document are being issued to correct the omission and the typographical error.
