FRUITLAND, N.M. (December 14, 2018) – Sundt Construction, Inc. (www.sundt.com) recently completed the APS Four Corners Selective Catalytic Reduction Retrofits. The design-build project added four selective catalytic reduction systems for nitrogen oxide emission control for Units 4 and 5 of the APS Power Plant. The selective catalytic reactors (SCR) used are the tallest in North America and the second-largest air pre-heaters in the world, at 60 feet in diameter. 
“The SCR project at Four Corners has several widespread benefits. The project provided work for the local skilled workforce, the operation of the facility will help maintain continued economic viability in the region, and the process upgrades will make a significant improvement in the overall regional air quality,” said Rich Keil, Sundt’s President of the Industrial Group.
Four Corners Generating Station has provided power to the area for 50 years. The generating station is powered by low-sulfur coal from the nearby Navajo mine and cooled by the nearby Morgan Lake. Four Corners provides 1570 megawatts of energy. The upgraded equipment will enable the plant to meet more stringent environmental standards through reducing emissions by eighty percent. The change in units is expected to provide more than $6.3 billion in economic value to the region over the next 30 years.
“I’ve been at the Four Corners facility for 38 years, and this is my third opportunity to work with Sundt on a large capital project,” said Bruce Salisbury, SCR Build Coordinator. “I have always enjoyed working with Sundt. They always work with a sense of urgency but do an excellent job of crafting a final finished product.”
Sundt began the project in August 2015 (working for AECOM, which held the prime contract).. The company self-performed much of the work at the site with its own skilled craft workforce. Specialized trades included precision millwrighting, boiler-making, structural ironworking, piping, concrete and electrical.
The site is located about 25 miles west of Farmington, New Mexico on the Navajo Nation.
