Hwy 62 – 75 Air Quality

Rehabilitation of Highway 62 West, Crater Lake National Park, Klamath County, Oregon



This section evaluates the potential impacts of the no-action alternative.

Air Quality

There would be no change to air quality as a result of the no-action alternative.

Cumulative Impacts. Past, present, and reasonably foreseeable future actions would not have long-term effects on air quality; any impacts would be short term, localized, and negligible. The no-action alternative would not contribute to these actions.

Conclusion. There would be no change in impacts to air quality from the no-action alternative. The no-action alternative would not contribute to cumulative impacts.

Because there would be no major adverse impacts to a resource or value whose conservation is (1) necessary to fulfill specific purposes identified in the park’s establishing legislation, (2) key to the natural or cultural integrity of the park or to opportunities for enjoyment of the park, or (3) identified as a goal in the park’s General Management Plan or other relevant National Park Service planning documents, there would be no impairment of park resources or values.
