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 use.* It is a significant new use to use the substance where the concentration of the substance in the product formulation intended for distribution in commerce exceeds 1% by weight.
(iv) *Release to water.* Requirements as specified in § 721.90(a)(4), (b)(4) and (c)(4), where N = 34.
(b) *Specific requirements.* The provisions of subpart A of this part apply to this section except as modified by this paragraph (b).
