It consists predominantly of hydrocarbons having carbon numbers in the range of C5 through C15. It boils in the range of approximately 36 °C to 265 °C (97 °F to 509 °F).) is subject to reporting under this section for the significant new uses described in paragraph (a)(2) of this section. The requirements of this rule do not apply to quantities of the PMN substances that have been blended into finished petroleum products or sent to a petroleum refinery for use as a chemical intermediate, or stored as described in the Distribution section of the order.(2) The significant new uses are: (i)Protection in the workplace. The significant new use is any exposure exceeding an 8 hour time weighted average (TWA) exposure limit of 1 part per million (ppm).(ii)Industrial, commercial, and consumer activities. Requirements as specified in § 721.80 . A significant new use is any use other than as a raw feedstock for refineries.(iii)Release to water. Requirements as specified in § 721.90(a)(4), (b)(4), and (c)(4) (N = 4).(b)Specific requirements.
