Environment, health and safety
Protecting the environment and keeping people safe are the top priorities of the Pine Bend refinery. Our refinery is one of the safest, cleanest, and most efficient refineries operating in the United States, and it continues to improve.
Since 1997 the refinery has lowered emissions of traditional criteria pollutants by approximately 69%, while increasing production to help meet demand for transportation fuels. The refinery has reduced total onsite emissions in 11 of the last 15 years, and its emissions per barrel are approximately 19% lower than other U.S. refineries.
In 2017 the Flint Hills Resources Pine Bend refinery was awarded the U.S. Environmental Protection Agency’s (EPA) ENERGY STAR® Partner of the Year Award in recognition of its superior energy management practices. In 2016 Flint Hills Resources Pine Bend refinery was recognized by the Association of American Railroads as an exemplary shipper, and in 2014 Pine Bend became the first facility in the country to be certified as a PRO-10 worksite. The refinery received the Governor’s Safety Award from the Minnesota Safety Council for the sixth time in 2014 and was recertified as a Minnesota STAR worksite through 2018 in 2013.
The Minnesota Pollution Control Agency has recognized the Pine Bend refinery was an outstanding wastewater treatment operator for four consecutive years.
Pine Bend has decreased OSHA-recordable injuries by more than 73% in the past 15 years and has surpassed 2 million workhours in recent years without a recordable injury.
In 2017 Flint Hills Resources Pine Bend refinery received two awards for strong rail safety performance including the Chemical Safety Excellence Award from CSX Corporation and the Thoroughbred Chemical Safety Award from Norfolk Southern Corporation. In 2016 Flint Hills Resources Pine Bend refinery was recognized by the Association of American Railroads as an exemplary shipper, and in 2014 Pine Bend became the first facility in the country to be certified as a PRO-10 worksite.
The refinery received the Governor’s Safety Award from the Minnesota Safety Council for the sixth time in 2014 and was recertified as a Minnesota STAR worksite in 2013. Pine Bend also received numerous safety awards in recent years from the American Fuel & Petrochemical Manufacturers.
The Pine Bend refinery is an industry leader in flare management.
The Pine Bend refinery began a water recycling program in 2006 that enables it to reuse treated water. The refinery’s wastewater treatment plant successfully processes 3.5 million gallons of water per day. The Minnesota Pollution Control Agency honored Pine Bend as an outstanding wastewater treatment operator for the past four years. The refinery has reduced its water use to just over half a gallon for every gallon of product produced.
The Pine Bend refinery is a member of Clean Air Minnesota, a group of businesses, units of government, and environmental organizations that was convened by Environmental Initiative to develop a set of strategies to clean up the air through proactive, voluntary approaches.
In addition, Pine Bend is a founding sponsor of Project Green Fleet, a collaborative effort with Environmental Initiative to install pollution control equipment in thousands of Minnesota school buses, heavy-duty trucks, and other diesel vehicles. Since the effort was kicked-off in 2005, Project Green Fleet has modified more than 3,200 Minnesota school buses and 1,300 diesel trucks with improvements that reduce diesel emissions and help keep Minnesota’s air clean. In 2014, Project Green Fleet completed its successful school bus retrofit program and launched a new major initiative to reduce emissions from Minnesota diesel construction vehicles, marine engines, rail equipment, and other heavy-duty diesel vehicles, thanks in part to a $1 million grant from Flint Hills Resources. The project was recognized by the EPA as a national model for improving air quality and earned one of two national Clean Air Excellence Awards.
Since 2000 Flint Hills Resources Pine Bend has partnered with Friends of the Mississippi River to restore 1,650 acres of natural prairie and oak savanna in an area known as the Pine Bend Bluffs Natural Area along the Mississippi River. The area provides critical habitat for both resident and migratory animals and is a migration corridor for millions of songbirds and 40% of North America’s waterfowl and shorebirds.
Restoration efforts have focused around the protection and enhancement of native prairie plants with prescribed burns and the removal of invasive plants, helping to restore the area to pre-settlement conditions.
The Pine Bend Bluffs Natural Area is an Environmental Initiative award winner for natural resource protection and is designated as an area of outstanding biological diversity by the Minnesota Department of Natural Resources.
Learn more about this effort in the Friends of the Mississippi River’s 2015 report.
Flint Hills Resources partners with environmental organizations to help restore the Pine Bend Bluffs to pre-settlement conditions and support natural wildlife habitats. Efforts include facilitating bluebird nesting, building snake hibernacula, and planting native plants to support monarch butterflies, among other initiatives.
In 2016, Flint Hills Resources started construction on a new state-of-the-art combined heat and power (CHP) system that will allow it to operate more efficiently while reducing greenhouse gas emissions from Minnesota’s current energy supply mix. The CHP system will use natural gas and a heat recovery process to produce approximately 50 megawatts of electricity, or roughly 40% of the energy required to power the refinery.
Since 2008, Flint Hills Resources has planted 500-1,000 trees in Dakota County each year that are native to Minnesota. Many of these trees are located near area parks and help fill in the natural flyway areas that birds use for migration.
Flint Hills Resources maintains a fully functioning, two-house fire department at the Pine Bend refinery. The fire department’s 132 crew members, including 87 refinery volunteers, receive ongoing training on all aspects of industrial emergency response and battle live, pressurized petroleum fires at an onsite training center. The Pine Bend Fire Department also provides mutual aid industrial fire training to the Rosemount, Eagan, Inver Grove Heights, and Hastings fire departments.
