Midstream oil and gas infrastructure comprises vast networks of gathering and transmission pipelines that connect upstream extraction to downstream consumption. In the United States (US), public policies and corporate decisions have prompted a wave of proposals for new gathering and transmission pipelines in recent years, raising the question: Who bears the burdens associated with the existing pipeline infrastructure in the US? With this in mind, we examined the density of natural gas gathering and transmission pipelines in the US, together with county-level data on social vulnerability. For the 2,261 US counties containing natural gas pipelines, we found a positive correlation between county-level pipeline density and an index of social vulnerability. In general, counties with more socially vulnerable populations have significantly higher pipeline densities than counties with less socially vulnerable populations. In particular, counties in the top quartile of social vulnerability tend to have pipeline densities that are much higher than pipeline densities for counties in the bottom quartile of social vulnerability. The difference grows larger for counties at the upper extremes of pipeline density within each group. We discuss some of the implications for the indigenous communities and others affected by recent expansions of oil and gas infrastructure. We offer recommendations aimed at improving ways in which decision-makers identify and address the societal impacts and environmental justice implications of midstream pipeline infrastructure.

美国天然气集输管道与社会脆弱性

中游石油和天然气基础设施包括庞大的收集和传输管道网络,将上游开采与下游消费连接起来。在美国,近年来,公共政策和企业决策引发了一波新的集输管道提案浪潮,引发了一个问题:谁承担了美国现有管道基础设施的相关负担?考虑到这一点,我们研究了美国天然气集输管道的密度,以及县级社会脆弱性数据。对于美国 2,261 个拥有天然气管道的县,我们发现县级管道密度与社会脆弱性指数之间存在正相关关系。一般来说,社会弱势人口较多的县的管道密度明显高于社会弱势人口较少的县。特别是,社会脆弱性排名前四分之一的县的管道密度往往远高于社会脆弱性排名后四分之一的县的管道密度。对于每组内管道密度最高的县,这种差异会更大。我们讨论了近期石油和天然气基础设施扩张对土著社区和其他受影响者的一些影响。我们提出的建议旨在改进决策者识别和解决中游管道基础设施的社会影响和环境正义影响的方式。
