|Views of Mount Washington under different fine particulate matter pollution concentrations and associate deciview levels.|
Whether soaking in a valley view between mountain peaks or witnessing a 360-degree mountain top vista, most hikers feel a sense of wonder when they look out on distant surroundings afforded by their ascents. AMC believes that clear views are worth protecting. We have worked for strong Clean Air Act (CAA) laws that reduce air pollution, e.g. fine particulates, which cause hazy views and negatively affect healthy outdoor recreation. There is an opportunity to comment now on the EPA’s proposed changes to the particulate matter national standards that could improve our health and our views.
- Current human-health standards: 15 μg/m3(annual) and 35 μg/m3 (daily)
- EPA proposed: 12-13 μg/m3 (annual) and 35 μg/m3 (daily)
- AMC Recommendation: 11 μg/m3 (annual)and 25 μg/m3 (daily)
- Current human-welfare standard: same as health standard
- EPA proposed: new urban visibility standard 28 or 30 deciviews (daily)*
- AMC Recommendation: national visibility standard of 18.6 deciviews (daily)
*other welfare effects would be set as same as health standard
Help us tell EPA to strengthen the health and visibility standards! Here is what you can do:
- Review the EPA proposal to change the current National Ambient Air Quality Standards for Particulate Matter.
AMC’s Fact Sheet (PDF 132 KB) on ozone and fine particulate pollution.
- Submit written comments by August 31, 2012 by emailing: a-and-r-Docket@epa.gov and denoting “Docket EPA-HQ-OAR-2007-0492” in the subject line.
- Attend the public hearing July 17, 2012 in Philadelphia, PA. See details here.

- Document the visibility on your hikes or when visiting one of our backcountry huts.
