VIDEO: A Sacred Trust
Threatened National Parks and Native Lands
Thank EPA for Taking Measures to Clean Up Desert Skies!
EPA has disapproved an inadequate plan submitted by Arizona, and replaced it with emission limits that will require common, cost-effective, modern controls on eight boilers at these three plants, all built in the 1970s with minimal-to-no controls.
Take Action! Please thank the EPA for its plan that requires significant pollution reductions from these park-polluting plants.
This video arises from efforts of both National Parks Conservation Association (NPCA) and Diné CARE to reduce air pollution from coal-fired power plants in the Southwest to improve poor regional air quality. Coal plant pollution degrades public health and the treasured landscapes of the Four Corners area. This film strives to elevate the profile of native voices advocating for better air quality- voices that are underrepresented in deliberations to require modern pollution controls at the two plants on the Navajo Nation (Navajo and Four Corners plants) and adjacent to these native lands (Cholla, Coronado, and San Juan).
The power plants listed below are subject to pollution control requirements under the Clean Air Act. The Environmental Protection Agency (EPA) must decide whether and how it will mitigate air pollution. We hope you will join us in advocating for EPA decisions that will require modern technology to significantly reduce emissions.

Current Status of Proposed Pollution Controls
| Navajo Generating Station Page, Arizona |
EPA has yet to propose any BART (Best Available Retrofit Technology) or pollution controls for this plant. |
|
Four Corners Power Plant
|
EPA required modern pollution controls for this plant which will result in 80%+ reductions in nitrogen oxide pollution. |
|
Cholla Generating Station |
EPA required 79%+ reductions in nitrogen oxide emissions, which can be accomplished through modern pollution controls. |
|
Coronado Generating Station |
EPA required 79%+ reductions in nitrogen oxide emissions, which can be accomplished through modern pollution controls. |
|
San Juan Generating Station |
EPA required modern pollution controls which will result in ~85% reductions in nitrogen oxide pollution. |
|
Apache Generating Station |
EPA required 83%+ reductions in nitrogen oxide emissions, which can be accomplished through modern pollution controls. |
