Flint Hills Resources has ongoing efforts to reduce emissions at its plants. A key component of the emissions reduction programs at its Texas and Minnesota refineries is the ability to reduce flaring – especially during times of startup, shutdown and malfunction. The company completed a four-year collaborative effort with the U.S. Environmental Protection Agency to develop and share best practices aimed at reducing emissions during these periods.
* Data for 2004-07 include Pine Bend and Corpus Christi West.
# 2008 includes data from Corpus Christi East and North Pole refineries for the first time. Flare time increased in 2008 due to one event in Alaska caused by improper equipment installation that was corrected and as a result of planned maintenance on the flare gas recovery unit at the Corpus Christi West plant.
