82 F. Supp. 3d 1201
D. Colo.2015Background
- The Navajo Mine supplies coal exclusively to the adjacent Four Corners Power Plant; the mine seeks a permit revision to expand into Area IV North to meet contractual coal obligations.
- OSM issued an Environmental Assessment (EA) and approved the 2011 permit revision, finding no significant environmental impact; petitioners challenged that EA under NEPA.
- Petitioners (environmental groups) argued OSM failed to analyze combustion-related impacts (combustion emissions and coal combustion waste) that would result from coal mined due to the permit revision.
- The mine and power plant are functionally integrated (mine-mouth plant); approval would allow combustion of an additional 12.7 million tons of coal over the contract term.
- The court evaluated standing, prudential mootness, NEPA scope (connected actions/indirect effects), and whether OSM adequately considered mercury deposition and other combustion-related impacts in the EA.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Standing to sue under NEPA | Petitioners allege procedural injury from inadequate NEPA analysis harming members who use the area | Respondents largely concede standing but dispute traceability/redressability | Court: Petitioners have Article III standing (procedural NEPA injury, causation, redressability) |
| Prudential mootness because an ongoing EIS exists | Pending EIS makes relief meaningless | OSM/NTEC: forthcoming EIS addresses combustion impacts so challenge is moot | Court: Not moot; injunctive relief (pause on ground-disturbing activity) could be meaningful; declines prudential mootness |
| Whether combustion-related impacts are within EA scope (connected actions / indirect effects) | Combustion impacts are indirect effects: but-for approval, coal would not be mined or combusted; effects are reasonably foreseeable given mine-plant interdependence | OSM: no need to analyze because status quo not changed, other agencies regulate combustion, limited OSM authority, pending EIS covers it | Court: Combustion impacts are indirect effects requiring NEPA analysis (but declines to decide connected-actions question) |
| Adequacy of EA re: mercury deposition and significant impact determination | EA failed to analyze combustion-related mercury deposition and its impacts on endangered species/ecosystem; an EIS may be required | OSM: EA cumulative analysis suffices; duplicative to rely on EPA/state analyses; limited authority to regulate plant emissions; pending EIS will address issues | Court: EA’s consideration of mercury and combustion effects was inadequate; remands for further NEPA analysis and OSM to determine if EIS is required |
