New Data: Yellowstone Winter Silence Still Disrupted by Snowmobile Noise

First Test Seen of Administration's Pledge to Put 'Conservation First' in

National Parks

    WASHINGTON, Oct. 23 /PRNewswire/ -- In what will trigger the first
 major test of the Bush Administration's recent pledge to put "conservation
 first" in national parks, new scientific findings of the National Park
 Service (NPS) show that snowmobile noise has exceeded Yellowstone's
 standards in three consecutive winters even as the number of snowmobiles
 entering the park has declined. For example, snowmobile-dominated vehicle
 noise was audible at Old Faithful between 60 and 80 percent of the time
 during the peak hours of 8 a.m. - 4 p.m. for nearly the entire 2005-06
 winter season, according to the 118- page National Park Service report now
 available at
     In response to the new data, the Coalition of National Park Service
 Retirees (CNPSR), a watchdog organization of 545 NPS veterans with more
 than 16,000 years of total NPS management experience, said the chronic
 snowmobile noise problem at Yellowstone interferes with visitors'
 opportunities to enjoy natural conditions in Yellowstone and conflicts
 directly with new Management Policies for the national parks adopted by the
 Bush administration earlier this year.
     The chronic noise at Old Faithful occurred with an average of just 263
 snowmobiles present on each of the sampling days. Moreover, the number of
 snowmobiles park-wide during the past three winters has averaged only 250
 per day; and yet the noise standards have been exceeded. Despite this,
 Senator Conrad Burns of Montana is seeking to authorize 720 snowmobiles per
 day in Yellowstone through a rider he has placed on the Senate's Interior
 Appropriations Bill.
     "How the administration responds to this conflict between snowmobile
 noise in Yellowstone and its newly-adopted policies will tell Americans a
 great deal about the administration's commitment to stewardship in the
 national parks," said CNPSR Executive Council Chairman Bill Wade, a former
 superintendent of Shenandoah National Park. "The new Management Policies
 were adopted with strong bipartisan support and the administration was
 widely and duly praised for its pledge to put conservation first in the
 national parks. But that pledge will be seen as a sham, and should be, if
 the administration fails to adhere to its policies in our first national
     Finalized in late August by Interior Secretary Dirk Kempthorne, the
 2006 Management Policies reaffirmed that the overarching responsibility of
 NPS is to conserve park resources in an "unimpaired" condition. Beyond
 this, the policies restored highly specific duties related to maintaining
 quiet and managing motorized use in the parks. These duties had been
 stripped in an earlier, highly controversial rewrite of the policies
 spearheaded by Paul Hoffman, a deputy assistant secretary of Interior at
 the time and former director of the Cody, Wyoming chamber of commerce.
     Famous for natural sounds such as hissing steam, rushing waterfalls and
 howling wolves, Yellowstone has more recently become known as the national
 park where rangers working around snowmobiles have suffered partial hearing
 loss. NPS now advises its employees to wear earplugs when they operate the
 same models of four-stroke snowmobiles used by visitors.
     NPS does not issue a similar warning to visitors. However, last year a
 nationally recognized expert in noise-induced hearing loss cautioned
 Yellowstone's superintendent that, based on NPS' data, visitors riding
 snowmobiles are at risk of damaging their hearing. Dr. Peter Rabinowitz of
 the Yale Occupational and Environmental Medicine Program urged Yellowstone
 to caution visitors that even when they are operating the newest models of
 park- approved snowmobiles that they are safer wearing hearing protection.
     NPS recently completed a report on noise monitoring conducted in
 Yellowstone last winter. Rather than health risks, the monitoring focused
 on impacts from snowmobile noise to the park's environment and to the
 opportunities of visitors to enjoy Yellowstone. NPS found:
     * "Major adverse effects" in the Old Faithful Geyser Basin,
 Yellowstone's most popular destination, as well as near Madison Junction.
 The agency says these impacts involve "an easily recognizable adverse
 effect on the natural soundscape and potential for its enjoyment."
     * Noise problems at Madison Junction reached the "major" adverse effect
 threshold on 75 percent of days NPS monitored.
     * At Old Faithful, snowmobile noise was "audible more than twice the
 time of snowcoaches."
     Rick Smith, a member of CNPSR's Executive Council and former acting
 superintendent of Yellowstone National Park, said: "The new findings
 underscore very similar monitoring results from the previous two winters in
 Yellowstone. They have demonstrated conclusively that the noise generated
 by a relatively small number of snowmobiles is depriving too many visitors
 of truly experiencing Yellowstone's unique sounds and the park's
 magnificent quiet. Many visitors will never have a second chance to visit
 Yellowstone in winter, so if their one visit is dominated by snowmobile
 noise, they are out of luck. This is not what Americans expect in their
 national parks. It is not what the new Management Policies prescribe. And
 it is not what this administration pledged when it assured Americans that
 conservation will come first in national treasures such as Yellowstone."
     The findings at Yellowstone conflict with the NPS Management Policies
 recently adopted by the Administration, including these precise duties:
     * 4.9 Soundscape Management - "The National Park Service will preserve,
 to the greatest extent possible, the natural soundscapes of parks."
     * 8.2 Visitor Use - "For the purpose of these policies, unacceptable
 impacts are impacts that, individually or cumulatively, would ...
 unreasonably interfere with ... the atmosphere of peace and tranquility, or
 the natural soundscape maintained in wilderness and natural, historic, or
 commemorative locations within the park."
     * 8.2.3 Use of Motorized Equipment - "Where such use is necessary and
 appropriate, the least impacting equipment, vehicles, and transportation
 systems should be used."
     Wade said: "Americans expect the highest standards in their national
 parks and nowhere is this truer than in Yellowstone. We believe that it is
 crucial for the administration to acknowledge the seriousness of the
 snowmobile noise problem in Yellowstone. New leaders in the Department of
 Interior and the National Park Service have a golden opportunity to give
 confidence to Americans who cherish their national parks by showing that --
 in Yellowstone of all places -- they will vigorously adhere to the new NPS
 Management Policies that earned widespread praise earlier this year."
     The 545 members of the Coalition of National Park Service Retirees are
 all former employees of the National Park Service with a combined 16,000
 years of stewardship of America's most precious natural and cultural
 resources. In their personal lives, CNPSR members reflect the broad
 spectrum of political affiliations. CNPSR members have served their country
 well, and their credibility and integrity in speaking out on national park
 issues should not go ignored. The Coalition counts among its members five
 former directors or deputy directors of the National Park Service; 24
 former regional directors or deputy regional directors; 31 former associate
 or assistant directors at the national or regional office level; 68 former
 division chiefs at the national or regional office level; and 130 former
 park superintendents or assistant superintendents. For more information,
