Targa Northern Delaware, a subsidiary of Targa Resources, has filed a full-court-press defense against New Mexico’s Environment Department in a case over alleged air pollution violations dating back years. The case involves a proposed $47.8 million fine for excess emissions at Targa's Red Hills natural gas processing plant in the Permian Basin. The company has been accused of failing to properly operate flare units at the Red Hills facility, operating within emission limits, submitting excess emission reports in the proper timeframe, and providing an analysis explaining the root cause of the emissions. So far, no agreement has been reached between the two sides. Critics are concerned that large companies may focus on fighting state regulation, while the state spends a significant fortune defending its rules.
