In the Federal Register issue of March 16, 2012, EPA published a direct final rule revoking certain testing requirements promulgated under the Toxic Substances Control Act (TSCA) for 10 chemical substances, including benzenesulfonic acid, [[4-[[4- (phenylamino)phenyl][4-(phenylimino)-2,5-cyclohexadien-1- ylidene]methyl]phenyl]amino]- (CAS No. 1324-76-1), also known as C.I. Pigment Blue 61. EPA received an adverse comment regarding C.I. Pigment Blue 61. This document withdraws the revocation of testing requirements for C.I. Pigment Blue 61 as described in the March 16, 2012 direct final rule. In withdrawing the revocation, this document also restores the original testing requirements as currently shown in the Code of Federal Regulations (CFR). Elsewhere in today's Federal Register, EPA is publishing a proposed rule revoking the same testing requirements for C.I. Pigment Blue 61 that were published in the March 16, 2012 direct final rule.
