(a) Chemical substance and significant new uses subject to reporting.

(1) The chemical substance identified as 1,4-benzenedicarboxylic acid, 1,4-bis(2-phenoxyethyl) ester (PMN P-19-36; CAS No. 25900-07-6) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section.

For purposes of § 721.63(a)(5), respirators must provide a National Institute for Occupational Safety and Health (NIOSH) assigned protection factor (APF) of at least 1,000. For purposes of § 721.63(a)(6), the airborne form(s) of the substance include particulate (including solids or liquid droplets).

(ii) Release to water. Requirements as specified in § 721.90(a)(4), (b)(4) and (c)(4), where N = 3.

(b) Specific requirements. The provisions of subpart A of this part may apply to this section except as modified by this paragraph (b).
