The delivery of Natural Gas via pipelines continues to be the most cost effective and safest delivery method. Studies continue to verify pipelines as the safest and most environmentally safe delivery method https://www.aga.org/research/fact-sheets/pipeline-safety/. The export of LNG has recently made the United States the number one exporter of LNG. The export of LNG strengthens the US economy and provides a source for our Allies to source compared to competitive nations that are not friendly to the United States. Natural Gas is also firing many of our electric generation plants and driving down the carbon footprint for these institutions making electric cars, LNG vehicles, and a whole new industry more environmentally friendly. The advances in trenchless technology as well as tried and trusted methods like auger boring used in conjunction with Guided Pilot Bore machines continue to make the installation and maintenance of pipelines among the safest ways to install and transport materials.
