The Crude Oil Pipelines dataset was updated on October 21, 2020 from the Energy Information Administration (EIA), with attribute data from the end of calendar year 2024 and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Major crude oil pipelines in the United States and selected crude oil pipelines in Canada as of January 2020. Layer includes interstate trunk lines and selected intrastate lines but excludes gathering lines. Based on publicly available data from a variety of sources with varying scales and levels of accuracy. This dataset is not intended to be viewed beyond 1:1,000,000 scale.

The Natural Gas Interstate and Intrastate Pipelines dataset was updated on October 21, 2020 from the Energy Information Administration (EIA), with attribute data from the end of calendar year 2024 and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). This is a polyline dataset representing the major natural gas transmission pipelines in the U.S. including interstate, intrastate, and gathering pipelines. These data were compiled by the U.S. Energy Information Administration from various sources including federal and state agencies, and other external sources such as company web pages and industry press. Updated January 2020. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/1529018

The Hydrocarbon Gas Liquids (HGL) Pipelines dataset was updated on October 21, 2020 from the Energy Information Administration (EIA), with attribute data from the end of calendar year 2024 and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Major hydrocarbon gas liquids (HGL) pipelines in the United States and selected HGL pipelines in Canada. This data includes interstate trunk lines and selected intrastate lines. Based on publicly available data from a variety of sources (including company websites and media reports) with varying scales and levels of accuracy. Updated January 2020.

The Alternative Fuel Corridors dataset was created in 2016 and was updated on October 21, 2024 with new Round 8 designations from the Federal Highway Administration (FHWA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The dataset is a highway layer of corridors, primarily along the NHS, that are designated as Corridor Ready or Corridor Pending. It includes designations of five types of alternative fuels, Electric Vehicle Charging (EV), Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), Propane (LPG), and Hydrogen. Corridor-ready segments currently contain a sufficient number of fueling facilities to allow for corridor travel with the designated alternative fuel, and to qualify for highway signage. Corridors that do not have sufficient alternative fuel facilities to support alternative fuel vehicle travel are designated as corridor pending.
