The latest NPS air quality data trend analysis report shows visibility, ozone, and atmospheric deposition conditions and trends for 1998–2007 and indicates whether or not individual parks are meeting NPS strategic air quality goals. The report shows 99% of parks show stable or improving visibility, 94% have stable or improving ozone concentrations, and 83% have stable or improving trends in atmospheric deposition. While improving trends certainly show progress, a stable trend in air quality may not be sufficient to protect an area already experiencing poor air quality.

The Environmental Protection Agency (EPA) is conducting a combined review of the secondary National Ambient Air Quality Standards for Nitrogen Oxides (NOx) and Sulfur Dioxide (SO2).
If the current amount of total nitrogen deposition measured at the high-elevation monitoring site in Rocky Mountain National Park (4 kg/ha/yr) was the same throughout the park, the amount of airborne nitrogen entering the park would be equivalent to 943,000 twenty-pound bags of fertilizer. more » archive »
