(vii) The guiding requirements described in this paragraph (l)(9) do not apply to Cave Falls Road.
(10)Are there limits upon the number of snowmobiles and snowcoaches permitted to operate in the park each day? As of December 15, 2014, the number of snowmobiles and snowcoaches permitted to operate in the park each day will be managed by transportation events, as follows:
(ii) No more than 110 transportation events may occur in Yellowstone National Park on any given day.
(iv) Four of the 50 snowmobile transportation events allowed each day are reserved for non-commercially guided groups, with one such group allowed per entrance per day. The Superintendent may adjust or terminate the Non-commercially Guided Snowmobile Access Program, or redistribute non-commercially guided transportation events, based upon impacts to park resources, park operations, utilization rates, visitor experiences, or other factors, after providing public notice in accordance with one or more methods listed in 36 CFR 1.7.
(viii) Snowmobile transportation events conducted by a commercial tour operator may not exceed an average of 7 snowmobiles, averaged over the winter season. However, snowmobile transportation events conducted by a commercial tour operator that consist entirely of snowmobiles meeting enhanced emission standards may not exceed an average of 8 snowmobiles, averaged over the winter season. For the 2014-2015 winter season only, snowmobile transportation events conducted by a commercial tour operator that consist of any snowmobile that does not meet the air emission requirements in paragraph (l)(6)(i)(B) of this section or the sound emission requirements in paragraph (l)(6)(ii)(B) of this section may not exceed an average of 7 snowmobiles, averaged daily.
(x) A commercial tour operator that is allocated a transportation event, but does not use it or exchange it can count that event as “0” against that commercial tour operator's daily and seasonal averages. A commercial tour operator that receives a transportation event from another concessioner, but does not use it, may also count that event as “0” against its daily and seasonal averages.
(xi) Up to 50 snowmobiles may enter Cave Falls Road each day.
(xii) Daily allocations and entrance distributions for transportation events are listed in the following table:
Daily Transportation Event Entry Limits by Park Entrance/Location
|Park entrance/location||Commercially guided
transportation events if all 50 snowmobile
events are used
transportation events if zero commercially
transportation events are used*
* The remaining 4 transportation events are reserved for non-commercially guided snowmobiles.
(xiii) The Superintendent may decrease the maximum number of transportation events allowed in the park each day, or make limited changes to the transportation events allocated to each entrance, after taking into consideration the location of wintering wildlife, appropriate snow cover, public safety, avalanche conditions, park operations, utilization rates, visitor experiences, or other factors. The Superintendent will provide public notice of changes by one or more of the methods listed in 36 CFR 1.7.
(xiv) For the 2013-2014 winter season only, the number of snowmobiles and snowcoaches allowed to operate in the park each day is limited to a certain number per entrance or location as set forth in the following table. During this period, all snowmobiles operated by park visitors must be accompanied by a commercial guide. Snowmobile parties must travel in a group of no more than 11 snowmobiles, including the guide.
Number of Snowmobiles and Snowcoaches Allowed in the Park on Any Day by Park Entrance/Location for the 2013-2014 Winter Season
|Park entrance/location||Commercially guided
|Commercially guided snowcoaches|
|North Entrance *||12||13|
|Old Faithful *||12||16|
* Commercially guided snowmobile tours originating at the North Entrance and Old Faithful are currently provided solely by one concessioner. Because this concessioner is the sole provider at both of these areas, this regulation allows reallocation of snowmobiles between the North Entrance and Old Faithful as necessary, so long as the total daily number of snowmobiles originating from the two locations does not exceed 24. For example, the concessioner could operate 6 snowmobiles at Old Faithful and 18 at the North Entrance if visitor demand warranted it. This will allow the concessioner to respond to changing visitor demand for commercially guided snowmobile tours, thus enhancing the availability of visitor services in Yellowstone.
(xv) Paragraph (l)(10)(xiv) remains in effect until March 15, 2014.
(11)How will the park monitor compliance with the required average and maximum size of transportation events? As of December 15, 2014:
(iii) Each commercial tour operator must submit a monthly report to the park that includes the information below about snowmobile and snowcoach use. We may require the report to be submitted more frequently than monthly if it becomes necessary to more closely monitor activities to protect natural or cultural resources in the park.
(A) Average group size for allocated transportation events during the previous month and for the winter season to date. Any transportation events that have been exchanged among commercial tour operators must be noted and the receiving party must include these transportation events in its reports.
(B) For each transportation event; the departure date, the duration of the trip (in days), the event type (snowmobile or snowcoach), the number of snowmobiles or snowcoaches, the number of visitors and guides, the entrance used, route, and primary destinations, and if the transportation event allocation was from another commercial tour operator.
(B) Maintain separate records for snowmobiles and snowcoaches that meet enhanced emission standards and those that do not to allow the park to measure compliance with required average and maximum sizes of transportation events.
(12)How will I know when I can operate a snowmobile or snowcoach in the park? The Superintendent will:
(i) Determine the start and end dates of the winter season, which will begin no earlier than December 15 and end no later than March 15 each year. The Superintendent will consider appropriate factors when determining the length of the winter season, including adequate snow cover, the location of wintering wildlife, public safety, resource protection, park operations, and use patterns. Based upon these factors, the Superintendent may determine that there will be no winter season for oversnow vehicles or that certain areas of the park may be closed to public OSV use.
(ii) Determine operating hours, dates, and use levels.
(iii) Notify the public of the start and end dates of the winter season, operating hours, dates, use levels, and any applicable changes through one or more of the methods listed in § 1.7 of this chapter.
