(2) The significant new uses are:

(i) *Protection in the workplace.* Requirements as specified in § 721.63(a)(1), (a)(4), (a)(6) (particulate, gas/vapor or a combination gas/vapor and particulate)), and (c). When determining which persons are reasonably likely to be exposed as required for § 721.63(a)(1) 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.

(ii) *Industrial, commercial, and consumer activities.* Requirements as specified in § 721.80(f),

(k) (analysis and reporting and limitations of maximum impurity levels of certain impurities), (o) and (q). It is a significant new use to use the PMN substance other than for water and oil repellent use on military protective clothing.

(iii) *Release to water.* Requirements as specified in § 721.90(a)(4), (b)(4), and (c)(4) where N=17.

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