# 721.11028 Alkylarylamine (generic).
(a) *Chemical substance and significant new uses subject to reporting.* (1) The chemical substance identified generically as alkylarylamine (PMN P-15-705) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section.
(2) The significant new uses are:
(i) *Protection in the workplace.* Requirements as specified in § 721.63(a)(1), (a)(2)(i), (ii), and (iii), (a)(3) and (4), 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, (a)(5) (respirators must provide a National Institute for Occupational Safety and Health (NIOSH) assigned protection factor (APF) of at least 1,000), (a)(6) (particulate), (a)(6)(v), (vi), (v), and (vi), (b)(concentration set at 0.1%), and (c).
(A) As an alternative to the respirator requirements in paragraph (a)(2)(i) of this section, a manufacturer or processor may choose to follow the new chemical exposure limit (NCEL) provision listed in the TSCA section 5(e) Order for this substance. The NCEL is 0.48 mg/m
<sup>3</sup> as an 8-hour time weighted average. Persons who wish to pursue NCELs as an alternative to § 721.63 respirator requirements may request to do so under § 721.30. Persons whose § 721.30 requests to use the NCELs approach are approved by EPA will be required to follow NCELs provisions comparable to those contained in the corresponding TSCA section 5(e) Order.
(B) [Reserved]
(ii) *Hazard communication.* Requirements as specified in § 721.72(a) through (e) (concentration set at 0.1%), (f), (g)(1)(i), (ii), (iv), (vi), (vii), and (ix), (g)(2)(i), (ii), and (iii), (use respiratory protection or maintain workplace airborne concentrations at or below an 8-hour time-weighted average of 0.48 mg/m
<sup>3</sup>), (g)(2)(v), (g)(3)(ii), (g)(4)(i), and (g)(5). Alternative hazard and warning statements that meet the criteria of the Globally Harmonized System (GHS) and OSHA Hazard Communication Standard may be used.
(iii) *Industrial, commercial, and consumer activities.* Requirements as specified in § 721.80(o) and (q). It is a significant new use to use the substance other than as a chemical intermediate or as an additive and octane booster in aviation fuels.
(iv) *Release to water.* Requirements as specified in § 721.90(a)(4), (b)(4), and (c)(4) where N=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 (i) and (k) are applicable to manufacturers and processors of this substance.
(2) *Limitations or revocation of certain notification requirements.* The provisions of § 721.185 apply to this section.
(3) *Determining whether a specific use is subject to this section.* The provisions of § 721.1725(b)(1) apply to paragraph (a)(2)(iii) of this section.
