New Mexico Interstate Transport and Regional Haze

EPA is issuing a final source-specific federal plan that will help protect public health and improve visibility at 16 of our most treasured parks including the Grand Canyon, Mesa Verde and Bandelier National Monument. As it has with states across the country, EPA has been working with the state of New Mexico to put in place a long over-due plan to address emissions that impair visibility in national parks and wilderness areas.

The federal plan relies on proven, cost-effective and widely used technologies to protect public health in New Mexico and neighboring states by cutting dangerous nitrogen oxide emissions by over 80 percent from one of the nation’s largest polluting power plants. These efforts will dramatically improve visibility in 16 park and wilderness areas in the southwestern US, decreasing the number of days with impaired scenic views and as a result, promoting local tourism.

In response to comments received on the proposal, EPA has extended the compliance timeline by two years, giving the facility five years to meet the requirement. Although the state plan New Mexico recently submitted to the agency did not provide a basis to delay today’s decision, EPA will review the plan promptly and remains committed to working with New Mexico on this important issue.
