El Paso Electric fined for air violations

El Paso Electric consent decree mandates emissions reductions, flue gas recirculation, boiler tune-ups, and compliance monitoring at the Rio Grande station, safeguarding air quality in Doña Ana County and curbing NOx, CO, and SO2 pollution.

A state district court approved a settlement that requires Texas-based El Paso Electric Co. to pay a $250,000 penalty for air quality violations at its power plant in southern New Mexico.

The settlement also requires El Paso Electric to provide $275,000 for supplemental environmental projects, including, as outlined in a submitted plan for the Rio Grande Power Plant, the installation of a flue gas recirculation system to reduce emissions at the Rio Grande Electric Power Generating Station.

Environment Secretary Ron Curry said the agreement, known as a consent decree, is designed to provide safeguards to protect regional air quality.

"We fought to ensure the company invests in supplemental environmental projects that will directly benefit the residents of Dona Ana County by providing for the reduction of harmful air pollution in the area," Curry said.

The agreement also calls for El Paso Electric to tune up its boilers at the plant. However, that's something the utility was planning as part of its annual maintenance, said Andy Ramirez, vice president for power generation.

The Environment Department filed a complaint against El Paso Electric last fall, alleging the plant exceeded emission rates for nitrogen oxides, carbon monoxide and sulfur dioxide.

But El Paso Electric, which filed a Texas rate case in 2017, argued that the plant was not in violation. Ramirez said the utility and the state differed in their interpretations of the emission limits and the calibration of the plant's equipment.

Ramirez said the consent decree, reflecting efforts to settle accusations with regulators, spells out what is required at the plant to prevent any future disagreements.

The plant's three units can generate 246 MW of electricity. They run primarily on natural gas, but fuel oil is stored at the site as a backup.

In a separate development, El Paso customers received refunds following regulatory proceedings as well.
