Air Quality

We make progress on
protecting clean air

The U.S. fuel and petrochemical manufacturing industry is committed to protecting our communities by proactively monitoring air quality around our refineries and petrochemical facilities. We use a variety of air-monitoring devices to detect pollutants in real-time, so we can respond to situations before they become problematic. We also use sensor data to analyze long-term trends in air quality, which allows our facilities to validate that they are minimizing emissions and protecting air quality. Together, these efforts ensure we maintain responsible operations that keep the air safe for our neighbors and communities.

The Spotlight

Our Sensor Networks Keep Communities Safe

Sophisticated sensors monitor air quality around refinery fencelines, detecting minuscule emissions so we can proactively ensure our operations don’t diminish air quality.

“We’re here for the long run, so we’re going to do it right.”

Flint Hills Resources Pine Bend Refinery


A single refinery may deploy hundreds of sensors and monitoring devices within and on the facility’s fenceline to continuously monitor air quality. These sensors can detect tiny amounts of volatile organic compounds, so we can pinpoint where pollutants are elevated near the refinery.

Our employees analyze this information, together with meteorological data, so we can identify changes quickly and take immediate action to prevent problems. This real-time analysis also enables us to notify nearby communities quickly if pollutants exceed safe levels.

“We want to be good stewards of the area to ensure the air here is just as good as everywhere else.”

Monitoring What Matters

How fenceline monitoring technology catches problems before they become problems.

Install: Hundreds of advanced sensors are placed both
inside and on the fenceline of a facility, creating a grid to
monitor emissions.

Monitor: Sensors continuously monitor the surrounding air quality and can detect minuscule amounts of emissions, such as volatile organic compounds (VOCs).

Analyze: Thousands of data points from sensors are reported and analyzed in real-time by both humans and computers to proactively detect any changes in air quality.

Validate: Results of continuous monitoring are regularly reported to the EPA, and our industry works collaboratively with the agency to ensure we are meeting or exceeding all standards and regulations.

Protect: We invest in these networks to keep our employees
and our neighbors safe, and we share data about air quality with
local communities.

Community and
Regulatory Reporting

Transparency is an essential part of our commitment to communities. We provide quarterly reports to help residents understand their air quality in comparison with other areas. We also report our monitoring data to the EPA’s Compliance and Emissions Data Reporting Interface (CEDRI), which is publicly accessible. We work closely with the agency to develop best practices around monitoring and reporting and to ensure we meet or exceed every industry standard and regulation.
