§ 721.12186 Heterocyclic epoxide polymer with mixed substituted glycols and acid anhydride (generic).
(a) Chemical substance and significant new uses subject to reporting. (1) The chemical substance identified generically as heterocyclic epoxide polymer with mixed substituted glycols and acid anhydride (PMN P-21-88; Accession No. 303458) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section. The requirements of this section do not apply to quantities of the substance after they have been completely reacted or cured (i.e., the substance has been reacted or cured to the extent that no release of the substance can be detected).
(2) The significant new uses are:
(i) Protection in the workplace. Requirements as specified in § 721.63(a)(1), (a)(3) through (6), and (c). When determining which persons are reasonably likely to be exposed as required for § 721.63(a)(1) and (4), engineering control measures (e.g., enclosure or confinement of the operation, general and local ventilation) or administrative control measures (e.g., workplace policies and procedures) shall be considered and implemented to prevent exposure, where feasible. 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 1000.
(ii) Hazard communication. Requirements as specified in § 721.72(a) through (d), (f), (g)(1), (g)(3)(iii), and (g)(5). For purposes of § 721.72(g)(1), this substance may cause: acute toxicity, skin irritation, serious eye damage, eye irritation, respiratory sensitization, skin sensitization, genetic toxicity, reproductive toxicity, and specific target organ toxicity. Alternative hazard and warning statements that meet the criteria of the Globally Harmonized System and OSHA Hazard Communication Standard may be used.
(iii) Industrial, commercial, and consumer activities. It is a significant new use to manufacture the substance as a solid without the use of a fume hood, dust collector, or other engineering controls with at least 25% combined capture and removal efficiency of aggregate releases of the total process, unless in an enclosed process. It is a significant new use to process or use the substance as a solid without the use of a fume hood, dust collector, or other engineering controls with at least 25% combined capture and removal efficiency, unless in an enclosed process.
(iv) Disposal. It is a significant new use to dispose of the substance or waste streams containing the substance other than by incineration or hazardous waste landfill in compliance with RCRA subtitle C.
(v) Release to water. Requirements as specified in § 721.90(a)(1), (b)(1), and (c)(1).
(b) Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph (b).
(1) Recordkeeping. Recordkeeping requirements as specified in § 721.125(a) through (k) are applicable to manufacturers, importers, and processors of this substance.
