40 CFR 721.12147: Cyclic sulfate (generic).

(a) Chemical substance and significant new uses subject to reporting. (1) The chemical substance identified generically as cyclic sulfate (PMNs P-18-281 and P-21-77; Accession No. 301816) 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 or incorporated into an article as defined in § 720.3(c).

(2) The significant new uses are:

(i) Protection in the workplace. Requirements as specified in § 721.63(a)(1), (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 1,000 or at least 50 when using less than the confidential annual production volume listed in the Order (measured on a year-to-year basis) of the substance at a use site and when receiving the substance at 1% or less in formulation, prior to the receipt of exposure monitoring results. Once exposure monitoring results are available, respirators must provide a NIOSH APF in accordance with Appendix 4 in the modified Order for P-18-281 (which lists required respiratory protection/action corresponding to different exposures), and exposure monitoring results must be equal to or less than 0.01 mg/m 3 as an 8-hour time-weighted average. Persons who wish to conduct monitoring in accordance with Appendix 4 in the modified Order for P-18-0281 as an alternative to § 721.63 respirator requirements may request to do so under § 721.30.

(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 corrosion, serious eye damage, skin sensitization, genetic toxicity, carcinogenicity, and specific target organ toxicity. Alternative hazard and warning statements that meet the criteria of the Globally Harmonized System and the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard may be used.

(iii) Industrial, commercial, and consumer activities. Requirements as specified in § 721.80(f). It is a significant new use to use the substance other than for the confidential uses allowed by the Orders for P-18-281 and P-21-77. It is a significant new use to process the substance above 5% in formulation. It is a significant new use to have releases to air of the substance unless exhaust from enclosed equipment is treated with combined capture and control technology that achieves a ≥99.8% capture and control efficiency.

(iv) Disposal. It is a significant new use to dispose of the substance or waste streams containing the substance other than by using the confidential method(s) described in the submission for P-21-77, or by landfill, deep well injection, or using a hazardous waste incinerator with ≥99.999% efficiency.

(v) Release to water. Requirements as specified in § 721.90(a)(4), (b)(4), and (c)(4) where N=152.

(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.

(2) Limitation or revocation of certain notification requirements. The provisions of § 721.185 apply to this section.
