In December 2012, a natural gas liquids leak began at a facility in Parachute, Colorado. Though the leak was discovered and stopped by early January 2013, the materials had already made a significant impact on the area.
At the end of April 2013, site regulatory authority was transferred from the Colorado Oil and Gas Conservation Commission (COGCC) to the Colorado Department of Public Health and Environment (CDPHE). Here is a collection of media, correspondence, questions and answers, diagrams and more for the public to access. Please note that most of this information stems from the Colorado Department of Public Health and Environment only. For additional information from prior to the authority transfer, refer to the Colorado Oil and Gas Conservation Commission website via the Contacts section.
