Sioux City, Iowa-Terra Nitrogen LP has committed to voluntarily reduce nitrogen oxide (NOx) emissions from its Verdigris, Okla., facility near Tulsa by approximately 425 st/y. The company will install ultra-low NOx burner technology to an existing ammonia reformer, thereby reducing the unit’s NOx emissions by approximately 60 percent, at a projected cost of $2 million. “Cleaner air is on the horizon for the Tulsa area thanks to efforts of Terra Nitrogen,” states Tulsa Mayor Kathy Taylor. “We congratulate them for this significant contribution to our air quality. Terra Nitrogen’s significant contribution stands out as a stellar example of stepping up to the plate for community partnership and cleaner air.” Taylor, Terra officials, and other local dignitaries announced the effort in March. The initiative helps Tulsa meet the terms of a recently approved 8-Hour Ozone Flex (8-Hr O3 Flex) agreement with the U.S. Environmental Protection Agency (EPA). The agreement supports and rewards innovative voluntary local strategies to reduce ground-level ozone, thereby improving air quality and helping comply with federal regulations. It is available only to areas that currently comply with ozone standards.
