2008 figures from the U.S. National Energy Technologies Laboratory show 90 million barrels of oil were extracted using Enhanced Oil Recovery from compressed CO2. The country has also spent $1 billion on 2,200 miles of CO2 transmission and distribution pipeline infrastructure.<ref>Antony Ingram, [http://www.csmonitor.com/Business/In-Gear/2012/0920/Is-CO2-a-latent-gaseous-gold "Is CO2 a latent gaseous gold?"] CSM, September 20, 2012.</ref>
In December 2013 the EPA exempted carbon dioxide injection from strict hazardous waste laws, classifying the wells used to inject CO2 underground for oil production in a category that offers less protection for drinking water, and loosening the reporting and monitoring requirements that some experts say are necessary to ensure the carbon stays underground. Companies are fighting an EPA proposal that would require tougher regulations if the carbon comes from power plants covered by the new federal CCS rules.<ref>[http://www.nwherald.com/2013/12/23/to-clean-up-coal-obama-pushes-more-oil-production/aj77w0f/?page=1 "To clean up coal, Obama pushes more oil production,"] AP, Dec. 23, 2013.</ref>
