In addition to doing our part to meet global needs for improved air quality, Cheniere is setting an example within our own company, managing emissions from air pollutants in every facet of our business, from development through operations. As our business continues to expand, we remain prudent in managing air emissions according to our internal policies, as well as state, federal and local regulatory requirements.
Compliance and oversight
We manage our operations in accordance with relevant state and federal laws and regulations. The U.S. EPA regulates our operations at the federal level, and the Louisiana Department of Environmental Quality (LDEQ) and the Texas Commission on Environmental Quality (TCEQ) are our primary state environmental regulators. We have also adopted several internal standards, procedures and guidelines — such as the air permit compliance and reporting procedure — to manage air quality.
Managing and monitoring emissions
We responsibly manage and monitor emissions from air pollutants across our operations. We select equipment that utilizes technology for air emission controls, such as NOx, and other criteria air pollutants.
Examples of emission controls employed at our facilities include low NOx burners and Dry Low Emissions (DLE) technology to reduce NOx emissions. In our pipeline operations, we use electric motor drives at certain compressor stations, which do not produce direct emissions, as well as technologies to reduce NOx and carbon monoxide emissions. These efforts help ensure that our emission control practices meet regulatory requirements and the emissions limits set in our air permits.
We implement stringent management and reporting mechanisms to monitor air quality at our facilities. Consistent with our environmental policy, we monitor and track our criteria pollutant emissions to determine our compliance status with respect to our hourly and annual emission limits. We perform LDAR at our facilities and compressor stations to monitor fugitive air emissions. Optical Gas Imaging (OGI) cameras or EPA Method 21 techniques are used to detect leaks across our operations on a quarterly to annual basis.
