SEC. 202. ENVIRONMENTALLY SENSITIVE AND HIGH-DENSITY POPULATION AREAS. (a) Pipeline Inventory.— Section 203 of the Hazardous Liquid Pipeline Safety Act of 1979 (49 U.S.C. App. 2002) is amended— (1) in subsection (j)— (A) by inserting “(and, to the extent the Secretary considers necessary, operators of gathering lines that are not regulated gathering lines as such term is defined pursuant to section 220(b))” after “subject to this title”; and (B) by inserting after the first sentence the following new sentence: “Such inventory shall also include an identification of each of the pipeline facilities and gathering lines of such operator which pass through an area described in regulations issued under subsection (m), whether or not such pipeline facility or gathering line is otherwise subject to regulation under this Act.”; and (2) by adding at the end the following new subsection: “(m) Environmentally Sensitive and High-Density Population Areas.— Not later than 2 years after the date of the enactment of this subsection, the Secretary shall issue regulations establishing criteria for the identification, by operators of pipeline facilities and operators of gathering lines, of— “(1) all pipeline facilities and gathering lines, whether otherwise subject to regulation under this Act or not, that are located in areas that are described, by the Secretary in consultation with the Administrator of the Environmental Protection Agency, as unusually sensitive to environmental damage in the event of a pipeline accident; and “(2) all pipeline facilities, whether otherwise subject to regulation under this Act or not, that— “(A) cross a navigable waterway, as such term is defined by the Secretary by regulation; or “(B) are located in areas that are described in such criteria as high-density population areas. Such regulations shall provide for such identification to be carried out through the inventory required under subsection (j). In describ-106 STAT. 3301ing areas that are unusually sensitive to environmental damage, the Secretary shall consider including earthquake zones and areas subject to substantial ground movements such as landslides; areas where ground water contamination would be likely in the event of the rupture of a pipeline facility; freshwater lakes, rivers, and waterways; and river deltas and other areas subject to soil erosion or subsidence from flooding or other water action, where pipeline facilities are likely to become exposed or undermined.”.
