Laws & Policies

 

Laws in Yellowstone National Park are established and enforced through a combination of federal regulations and site-specific rules tailored to the park's unique needs. At the core of this legal framework is Title 36 of the Code of Federal Regulations (CFR), which outlines the general rules governing all National Park Service lands. However, each park also faces distinct challenges and conditions, which is why Yellowstone’s superintendent issues a compendium—a document that supplements the CFR with local regulations specific to the park.

Together, the CFR and the superintendent’s compendium provide the legal basis for protecting Yellowstone’s natural and cultural resources while ensuring public safety and enjoyment. The following commonly cited regulations outline activities that are prohibited in Yellowstone:

• Willfully remaining near or approaching wildlife, including nesting birds, within any distance that disturbs or displaces the animal.
• Hunting or feeding wildlife.
• Traveling off boardwalks or designated trails in hydrothermal areas.
• Throwing anything into thermal features.
• Swimming in hot springs.
• Removing or possessing natural or cultural resources (such as wildflowers, antlers, rocks, and arrowheads).
• Leaving detachable side mirrors attached when not pulling trailers.
• Traveling off-road by vehicle or bicycle.
• Camping outside of designated areas.
• Spotlighting wildlife (viewing with lights).
• Imitating elk calls or using buglers. Imitating wolf howls.
• Using electronic equipment capable of tracking wildlife
• Launching, landing, or operating unmanned aircraft (drones) on lands and waters.
• Smoking is prohibited in geyser basins or on trails. There is no smoking in buildings or within 25 feet of building entrances.
• Bringing firearms in certain facilities in this park (such as visitor centers and government offices): those places are marked with signs at all public entrances.

Introduction to the Superintendent's Compendium

SUPERINTENDENT'S COMPENDIUM DESCRIBED

The Superintendent’s Compendium does not repeat regulations found in Title 36 Code of Federal Regulations (36 CFR), United States Code and other CFR Titles, which are enforced without further elaboration at the park level. The Superintendent’s Compendium is the summary of park specific rules implemented under 36 CFR. It serves as public notice, identifies areas closed for public use, provides a list of activities requiring either a special use permit or reservation, and elaborates on public use and resource protection regulations pertaining specifically to the administration of the park.

The regulations contained in 36 CFR, Parts 1-7, are the basic mechanism used by the National Park Service (NPS) to preserve and protect the natural and cultural resources of the park and to protect visitors and property within the park. Parts 1 through 6 are general regulations applicable to all areas of the National Park system, and Part 7 contains special regulations specific to individual parks. Each of these Parts has many sections and subsections articulating specific provisions. Within some of these Part 1-7 sections and subsections, the Superintendent is granted discretionary authority to develop local rules to be responsive to the needs of a specific park resource or activity, park plan, program, and/or special needs of the general public.

This Compendium should be used in conjunction with Title 36 CFR, Parts 1-7, to more fully understand the regulations governing the use and enjoyment of all the areas of the National Park System.

A copy of Title 36, CFR, can be purchased from the U.S. Government Printing Office or found on the Internet at:

https://www.ecfr.gov/cgi-bin/text-idx?tpl=/ecfrbrowse/Title36/36tab_02.tpl

Laws and Policies Allowing the Superintendent to Develop This Compendium

The National Park Service (NPS) is granted broad statutory authority under 54 United States Code (U.S.C.) Section 100101 et.seq. (Omnibus Public Land Management Act of 2009, previously Organic Act of 1916, as amended) to “…regulate the use of the National Park System by means and measures that conform to the fundamental purpose of the System units, which purpose is to conserve the scenery, natural and historic objects, and wild life in the System units and to provide for the enjoyment of the scenery, natural and historic objects, and wild life in such manner and by such means as will leave them unimpaired for the enjoyment of future generations.” [54 U.S.C. Section 100101(a)].

In 1970, Congress amended the NPS Organic Act to clarify its intentions as to the overall mission of the NPS. Through the General Authorities Act of 1970 (16 U.S.C. Sections 1a1-1a8), Congress brought all areas administered by the NPS into one National Park System and directed the NPS to manage all areas under its administration consistent with the Organic Act of 1916.

In 1978, Congress amended the General Authorities Act of 1970 and reasserted System-wide the high standard of protection defined in the original Organic Act by stating “Congress further reaffirms, declares, and directs that the promotion and regulation of the various areas of the National Park System, as defined by Section 1 of this Title, shall be consistent with and founded in the purpose established by Section 1 of this Title, to the common benefit of all people of the United States.”

54 U.S.C. Section 100501 defines the National Park System as “… any area of land and water administered by the Secretary, acting through the Director, for park, monument, historic, parkway, recreational, or other purposes.”

In addition to the above statutory authority, the Superintendent is guided by established NPS policy as found in the NPS Management Policies (2006). The Superintendent is also guided by more specific policies promulgated by the Director, National Park Service, in the form of Director’s Orders. As stated in the Management Policies, the primary responsibility of the NPS is to protect and preserve our national natural and cultural resources while providing for the enjoyment of these resources by visitor and other users, as long as use does not impair specific park resources or overall visitor experience. The appropriateness of any particular visitor use or recreational experience is resource-based and will vary from park to park; therefore, a use or activity that is appropriate in one park area may not be appropriate in another. The Superintendent is directed to analyze overall park use and determine if any particular use is appropriate. Where conflict arises between use and resource protection, where the Superintendent has a reasonable basis to believe a resource is or would become impaired, then that Superintendent is obliged to place limitations on public use.

Consistency of This Compendium with Applicable Federal Law and Requirements

The Superintendent’s Compendium is not considered a significant rule requiring review by the Office of Management and Budget under Executive Order 12866. In addition, this Compendium will not have a significant economic effect on a number of small entities nor impose a significant cost on any local, state or tribal government or private organization, and therefore does not fall under the requirements of the Regulatory Flexibility Act or Unfunded Mandates Reform Act.

The actions and requirements described in this Compendium are found to be categorically excluded from further compliance with the procedural requirements of the National Environmental Policy Act (NEPA) in Department of the Interior (DOI) Guidelines 516 DM 12 and as such, an Environmental Assessment will not be prepared.

Development of the Requirements of the Superintendent’s Compendium

As outlined above, the NPS has broad authority and responsibility to determine what types of uses and activities are appropriate in any particular National Park System area. The requirements of the Superintendent’s Compendium are developed through an analysis and determination process. The decision criteria used during this process are:

• Is the use or activity consistent with the NPS Organic Act and NPS policy?

• Is the use or activity consistent and compatible with the park’s enabling legislation, management objectives, and corresponding management plans?

• Will the use or activity injure the park’s protected natural and cultural resources and other protected values?

• Will the use or activity disturb or be in conflict with wildlife, vegetation, and environmental protection actions and values?

• Will the use or activity conflict with or be incompatible with traditional park uses and activities?

• Will the use or activity compromise employee or public safety?

Applicability of the Compendium

The rules contained in this Compendium apply to all persons entering, using, visiting or otherwise present on federally owned lands, including submerged lands, and waters administered by the NPS within the legislative boundaries of the park. This includes all waters subject to the jurisdiction of the United States, including all navigable waters.

The rules contained in this Compendium shall not be construed to prohibit administrative activities conducted by the National Park Service, or its agents, in accordance with approved general management and resource management plans, or in emergency operations involving threats to life, property, or park resources.

Enforcement of Compendium Requirements

NPS Law Enforcement Park Rangers enforce the requirements of the United State Code, 36 CFR, and this Superintendent’s Compendium.

Penalties for Not Adhering to the Compendium Requirements

A person who violates any provision of the regulations found in 36 CFR, Parts 1- 7, or provisions of this Compendium, is subject to a fine as provided by law (18 U.S.C. 3571) up to $5,000 for individuals and $10,000 for organizations, or by imprisonment not exceeding six months (18 U.S.C. 3559), or both, and shall be adjudged to pay all court costs associated with any court proceedings. In addition, to any fines or imprisonment an individual may be subject to a period of probation not to exceed five years in length (18 USC 3561).

  14. Swan Lake

  15. Floating Island Lake

  16. Molly Islands

  17. Ice Lake

Determination: The Superintendent has determined that this closure is necessary for the protection of bird species during the sensitive nesting period and that a ¼ mile distance is reasonable considering U.S. Fish and Wildlife Service guidance. Should documentation of fledging or nesting failure occur earlier than September 15th, closures may be lifted by the removal of posted signs.

Caves

• All caves within the park are closed to public use, except when a permit has been issued by the Superintendent.

Determination: This public use limit has been established in accordance with the Federal Cave Resource Protection Act of 1988 (16 USC §§4301-4309) and departmental policy, which states all caves located on NPS lands are “significant caves.” The permit requirement is done to protect sensitive cave resources and provides a protection for the public from potentially accessing areas with concentrated toxic gas.

McMinn Bench Sheep Closure:

• The McMinn Bench sheep closure is closed to all public access (see map).

Determination: The Superintendent has determined this closure is necessary for the protection and repopulation of Bighorn Sheep in Yellowstone National Park and the Greater Yellowstone Ecosystem.

Elk Calving Closures:

• Beginning in approximately mid-May through approximately mid-June and/or when signed as closed, the Mammoth Parade Grounds are closed to all foot travel (see map).

The National Park Service (NPS) has determined that cow elk become aggressive and territorial during the spring calving season and in recent years have caused serious injuries to employees and visitors in the Mammoth area. In an effort to protect humans from dangerous surprise encounters with elk, the Parade Grounds have been posted as closed to all travel during the duration of calving season (approximate dates of mid-May to mid-June). While elk may be present in many different locations of the Mammoth developed area, the Parade Grounds have pedestrian foot paths through sage brush areas where elk calves are easily stashed, and the elk can be difficult to see until a person is too close. An elk attack resulting in serious injury occurred on a pedestrian path on the Parade Ground during the 2019 calving season.

Construction Areas

• Construction or demolition areas are closed to public access except where a designated route and means of travel has been established by the Superintendent.

Determination: The Superintendent has determined that this prohibition is necessary for public and traffic safety.

Jumping, Diving, Rappelling

• Jumping, diving, or rappelling off any bridge, structure, or natural feature in the park is prohibited.

Determination: The Superintendent has determined this closure is necessary for public and employee safety, as well as resource protection.

Unmanned Aerial Systems

• Launching, landing, or operating an unmanned aircraft from or on lands and waters administered by the National Park service within Yellowstone National Park is prohibited except as approved in writing by the Superintendent.

Determination: The Superintendent has determined that unmanaged or unrestricted recreational use of unmanned aircraft within Yellowstone National Park will conflict with, or impact, a variety of park uses including visitor experience of unimpaired view sheds; the disturbance, displacement or harassment of park wildlife to include threatened and endangered species present potential for impacts or damage to sensitive thermal areas; creation of public safety hazards per operation near roadways or large aggregations of visitors, and visual or aural impacts to wilderness character and values within the park backcountry. Less restrictive measures were not considered sufficient due to the rapidly expanding and evolving use of UAs throughout the world. Section 1.5 of NPS Management Policies 2006 provide that a new form of park use may be allowed within a park only after a determination has been made by the park Superintendent that it will not result in unacceptable impacts on park resources and values.

Firearm Ranges

• All firearm ranges, to include the administrative roads that accesses them, are closed to public access.

Determination: The Superintendent has determined this closure is necessary for public and employee safety, as well as resource protection.

Obsidian Cliff:

• Obsidian Cliff is closed to all public access.

• For the purposes of this part, “Obsidian Cliff” means all areas within the following exterior boundary: a straight line from 44°50’55.00” N, 110°44’07.94” to the peak of Horseshoe Hill; a straight line from the peak of Horseshoe Hill to the west bank of Solfatara Creek; along the western bank of Solfatara Creek to its intersection with the Solfatara Creek trail; 100 feet off the north edge of Solfatara Creek Trail to Solfatara North trailhead; 100 feet off the east edge of Grand Loop Road to 44°50’55.00”N, 110°44’07.94”.

Determination: The Superintendent has determined this closure is necessary to provide for the protection of cultural resources associated with Obsidian Cliff National Historic Landmark. The values associated with Obsidian Cliff are still strong today, making recreational activities at the site inappropriate.

Road Closures:

• Roads closed to non-official use: All roads, including service and administrative roads, so designated by signs and/or locked gates, or barricaded with logs and/or boulders. (Foot traffic is permitted unless specifically posted otherwise. Pets and bicycles are prohibited.)

• Firehole Canyon Drive is closed to wheeled buses, trailers and recreational vehicles.

• Starting November 1st until spring opening in April or May, Grand Loop Road and park entrance roads are closed to wheeled motor vehicle use by the public, except for the following sections of park road which remain open year-round:

  1. North Entrance Station to Mammoth Hot Springs.

  2. Mammoth Hot Springs to Upper Terrace Drive.

  3. Mammoth Hot Springs to Tower Junction.

  4. Tower Junction to the Northeast Entrance Station.

• Firehole Lake Drive is closed to vehicles weighting six tons or more at the direction of Federal Highways.

Determination: The Superintendent has determined that these use prohibitions and restrictions are necessary for public safety and resource protection.

Stephens Creek Administrative Facility:

• For the purpose of this part, “Stephens Creek Administrative Facility” means Stephens Creek access road, Stephens Creek corral, Stephens Creek barn and infrastructure, Stephens Creek firearms range, and the surrounding area as fenced and signed and as shown on the following map (see map).

Determination: The Superintendent has determined that this closure is necessary for resource protection, as well as public and employee safety.

Storm Point Trail Area:

• The Storm Point Trail in the vicinity of Yellowstone Lake is closed to all off trail travel as marked in the map below (see map) and signs placed at the closure.

Determination: The Superintendent has determined this closure is necessary for the protection and repopulation of Sand Verbena, a rare endemic plant in Yellowstone National Park and the Greater Yellowstone Ecosystem.

Sylvan Pass Avalanche Control Area:

• For the purposes of this part, “Sylvan Pass Avalanche Control Area” means the entire south aspect of Hoyt Peak, from a point 1.5 miles east of Avalanche Peak Trailhead to a point 1.6 miles east of Avalanche Peak Trailhead.

• The Sylvan Pass Avalanche Control Area is closed to all public access.

Determination: The Superintendent has closed this area year-round for public safety. Over the winter months, NPS staff conduct avalanche mitigation operations, to include the use of explosive rounds. Regardless of season, the area listed above may contain unexploded ordinances.

• The Sylvan Pass howitzer platform and administrative road that accesses the platform is closed to public access.

Determination: The Superintendent has closed this area for public safety. Over the winter months, NPS staff conduct avalanche mitigation operations, to include the use of explosive rounds fired off from this location.

These restrictions have been determined necessary to provide for visitor safety and protect thermal and natural resources.

(a)(2) Designate areas for a specific use or activity or impose conditions or restrictions on a use or activity.

Activity Use Restriction

• Use of remote controlled still photography, videography, and audio recording devices is prohibited.

Determination: The Superintendent has determined this closure is necessary for public and employee safety, as well as resource protection.

Boating and Water Use Activities:

Aquatic invasive species (AIS) inspections.

• A Yellowstone AIS inspection, as specified in the sections below, is required to obtain a general permit for boating in the park.

• AIS inspections will be completed by an authorized inspector from the park on all vessels and related equipment that will contact park waters.

• Following an AIS inspection, the Yellowstone AIS decal must be displayed on the boat permit decal, which must be displayed on the vessel in accordance with the boating regulations.

• The following are required to obtain an AIS decal:

  1. All vessels and related equipment must pass an AIS inspection. Yellowstone requires all watercraft to be cleaned, drained, and dried prior to launch.

  2. If non-native Dreissenid mussels are present on a vessel or related equipment, or the vessel or equipment cannot be adequately decontaminated of other AIS, the contaminated vessel or related equipment will be subject to a 30 day quarantine before another inspection will be completed which is subject to the requirements of this part.

  3. All vessels must not have a ballast tank or similar areas that cannot be visually inspected, except as specifically authorized by the Superintendent.

• A boat permit issued in accordance with this part is only valid during the dates specified on the AIS decal, or until the vessel or related equipment exits the park.

• All vessels and related equipment, regardless of previous AIS inspections, must be re- inspected, in accordance with this part, upon reentry and intended launch into Yellowstone National Park waters.

• It is prohibited to allow any vessel or related equipment to contact any park waters without a valid Yellowstone AIS inspection or seal as specified in this part.

Determination: The Superintendent established this restriction for the protection of natural resources and to address the risk of introducing Dreissenid mussels and other (AIS) to Yellowstone National Park waters. Dreissenid mussels are a highly invasive species and have caused irreversible changes in waterways in the Midwestern and Eastern United States and in the Colorado River basin, to include Lake Mead and Lake Powell. Sealed internal water ballast tanks pose an elevated risk of accidental transportation and introduction of AIS because they are less likely to completely drain or be fully decontaminated. In addition, Yellowstone National Park requires an inspection of all watercraft to make sure they are cleaned, drained, and dry, and this is not possible with sealed tanks. A general permit is required to boat in the park, as referenced in 36 CFR §7.13(d)(1)(i). The Superintendent has determined an AIS inspection and sections detailed in this part are necessary to obtain a general permit for boating in the park to prevent the introduction and spread of AIS in Yellowstone National Park waters.

• All bilge and ballast plugs or other barriers that prevent water drainage from a vessel shall be removed and remain open while a vessel is being stored, left unattended, or transported by land within the park.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

• Anchoring a vessel on Yellowstone Lake in the following locations is prohibited:

1. Bridge Bay Marina.

2. Grant Village Launch Ramp Lagoon.

3. Within 300 yards of the shoreline between Lake Hotel and the entrance to Bridge Bay Marina.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

• Anchoring or beaching any vessel overnight in the park is prohibited, except if a person has an active and valid Yellowstone National Park Backcountry Use Permit.

• Docks on Yellowstone Lake are designated for Yellowstone National Park Backcountry Use Permittees. Persons without a Yellowstone National Park Backcountry Use Permit may only use these docks when the associated backcountry campsite is not in use.

• It is prohibited to transport a vessel or related equipment that is known to have invasive species attached through the park.

• Landing or beaching a vessel in the following locations is prohibited:

  1. In or within 25 yards of a thermal area, except at the designated boat landing area for Shoshone Geyser Basin.

  2. In an area closed to public use.

  3. In areas as designated by signs or as posted on maps in visitor use areas.

  4. On the shoreline of Yellowstone Lake between Little Thumb Creek and the south end of West Thumb Geyser Basin.

• It is prohibited to operate a vessel over submerged thermal area(s) where doing so damages the thermal area. Striking a thermal area, both on shore or underwater, with a vessel or anything from a vessel, such as with a paddle, pole, or anchor is also prohibited.

• Power-driven vessels on Yellowstone Lake may be used in areas restricted to hand-propelled vessels if the device that powers the vessel has been completely removed from the transom or is non-operational and completely fixed out of the water.

• Power-driven vessels from Lewis Lake may be used on Shoshone Lake only if the device that powers the vessel has been removed. Storage requirements for the device are detailed in this Compendium under the Section V: General 36 CFR Regulations: 36 CFR §2.22(a)(2).

• The park’s boating season begins the Saturday immediately prior to Memorial Day and ends October 31. Boating outside of these dates is prohibited.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

Cooke City Area Resident Permit Restrictions

• In lieu of paying a Yellowstone National Park Recreation Fee, Cooke City area residents may obtain a free permit, as authorized by the Superintendent, for non-recreational travel through the park between the North and Northeast Entrances.

Determination: The Superintendent has determined that this is necessary to protect the resource and enhance public safety and accessibility.

Resource Protection:

• The possession or consumption of food and beverages is prohibited in all thermal areas, except when contained in a pack like container for carrying purposes. Water is not included in this prohibition.

Determination: The Superintendent has determined that this restriction is necessary to protect and prevent impact to thermal resources.

• Transporting or hauling plant products, plant by products, plant waste products, or minerals into or through the park is prohibited, except for securely wrapped State certified weed-free hay or hay pellets, hay cubes, or grain may be transported. Or, if a person has received written authorization from the Superintendent.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

Wildlife Protection:

• The possession of Bear Spray for the strict purposes of protecting life and property against aggressive wildlife is permitted within the park.

Determination: The Superintendent has determined that the use of Bear Spray in a manner consistent with IGBC recommendation is appropriate as a deterrent to negative human/bear encounters.

• The use or possession of any radio electronic signal receiving device capable of being set at wildlife research operation frequencies assigned to NPS, U.S. Fish and Wildlife Service, Interagency Bear Management Team or any other permitted wildlife research organization within Yellowstone National Park is prohibited for the purposes of pursuing, tracking, harassing, or viewing wildlife or attempting to do any of the above.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

  7. Entities that have a commercial use authorization application denied or an authorization suspended or revoked for administrative or criminal violations may not enter the park under the commercial entry fee for the applicable duration of denial or revocation. This restriction excludes entities that applied for a CUA but were denied based on the activity not fitting a CUA category, but who then opt to provide road-based tours under the commercial tour fee.

• Employee motor vehicle permits issued in accordance with 36 CFR §7.13(b)(1) and (2) are only valid while the person is employed within the park and must be surrendered upon termination of employment.

Determination: The Superintendent has determined this condition is necessary for the proper use of the park by those no longer employed within the park.

• Gyroscopically Controlled Mobility Devices

1. The use of a Segway or other similar gyroscopically controlled device, in lieu of a manual or motorized wheelchair, is allowed by persons with disabilities who would otherwise only have the option of using a manual or power wheelchair under the following conditions:
   1. A person using a Segway or a similar gyroscopically controlled device in the park would be medically determined to have a permanent disability that severely limits one or more major life functions. A permanent disability is a permanent physical, mental, or sensory impairment that substantially limits one or more major life activities, such as caring for oneself, performing manual task, walking, seeing, hearing, speaking, breathing, learning and working.

   2. Persons claiming disability will show proof of medically determined permanent disability or eligibility for receiving benefits under federal law following the guidelines in effect for obtaining an America the Beautiful Access Pass (e.g. a statement by a license physician).

• Camping must be out of sight and at least ¼ mile from park roads, developed areas, patrol cabins, thermal areas and other backcountry campers.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary for public safety and resource protection.

(d) Food storage conditions:

• The following definitions, established by the Superintendent, apply to the food storage restrictions listed in this section:

1. Food means any item with a scent or any substance, except for water, that is eaten, drunk, or otherwise taken into the body by humans, pets, horses and pack animals, service animals, and livestock.
2. Equipment used to cook or store food means any cooking utensils; pots; pans; plates; cups; stoves; grills; coolers, regardless of contents; storage containers and bags that contain or have previously contained food, except Bear Resistant Food Containers; beverage containers; pet food bowls; and any other equipment and cooking or storage item that relates to food.

Determination: The Superintendent has established these definitions to clearly identify the items addressed in the food storage restrictions below. The definitions above are defined based on items park wildlife have been known to obtain and from which they have become food conditioned. The Superintendent has determined these definitions are necessary and considered the least restrictive means to protect park wildlife and the public.

• In all park areas all food, lawfully taken fish or wildlife, garbage, and equipment used to cook or store food must be kept sealed in a vehicle, or in a camping unit that is constructed of solid, non-pliable material, or in a Bear Resistant Food Container (BRFC), or suspended at least 10 feet above the ground and 4 feet horizontally from a post, tree trunk, or other object, or suspended on an NPS established and designated food hanging pole. This restriction does not apply to park residents who are in compliance with the food storage conditions outlined in the Yellowstone National Park Housing Plan or to established NPS grills and fire grates in housing areas, picnic areas and campgrounds.

Determination: The Superintendent has implemented food storage restrictions for the entire park to prevent park wildlife from obtaining food and becoming food conditioned, especially Black and Grizzly Bears. The Superintendent has determined these restrictions are necessary and the least restrictive means to protect park wildlife and the public. The Superintendent has added BRFCs and NPS established and designated food hanging poles as a legal means to store food because they are constructed to prevent park wildlife from obtaining food and becoming food conditioned. In some areas, NPS established bear resistant containers and food hanging poles may be the only food storage option aside from BRFCs. The Superintendent has determined these options help prevent further restrictions on the public while protecting park wildlife and the public.

• The following conditions apply when using a BRFC for food storage:

1. In all areas, a BRFC must properly function in designed condition and be secured as prescribed by the manufacturer.
2. In backcountry campsites, a BRFC must be stored within core camp.
3. When undesignated camping, a BRFC must be stored 100 yards from any sleeping area.
4. In developed, frontcountry areas, a BRFC must be kept in a vehicle, or in a camping unit that is constructed of solid, non-pliable material.
5. During the winter season BRFCs shall be utilized for frontcountry food storage in the interior, oversnow portions of the park. BRFCs may be stored on the exterior of a vehicle or on a snowmobile or tow sled.

Determination: Although BRFCs are designed to prohibit bears from accessing the contents within, the smells associated with them may still attract wildlife into camping areas. Requiring BRFCs to be stored in the manner above has been determined necessary by the Superintendent to prevent negative human and wildlife interactions, especially involving Black and Grizzly Bears. The Superintendent has determined these are the least restrictive means to protect park wildlife and the public.

• All refuse receptacles placed outdoors are only designated as an approved method for dumping if it is of bear-proof construction or placed inside bear-proof enclosures.

Determination: The Superintendent has determined this condition is necessary to prevent park wildlife from becoming food conditioned, namely Black and Grizzly Bears. The Superintendent has determined this is the least restrictive means to protect park wildlife and the public.

2.11—Picnicking

• Backcountry campsites and boat docks associated with backcountry campsites on Yellowstone Lake may be used for picnicking unless the backcountry site is being occupied by a person with an active and valid Yellowstone National Park Backcountry Use Permit.

Determination: The Superintendent has determined these picnicking restrictions are necessary and the least restrictive means to avoid conflict between park users.

2.13—Fires

(a)(1) Designated areas, receptacles and conditions for lighting and maintaining a fire:

• Except when seasonal fire restrictions based on local fire danger ratings have been established by the Superintendent, fires are permitted within the confines of NPS designated and installed fire rings, grills, or grates in the following locations:

1. Picnic areas, unless the NPS has not designated and installed fire rings, grills or grates.
2. All frontcountry campgrounds.
3. All backcountry sites, unless designated otherwise in a Yellowstone National Park Backcountry Use Permit.
4. Employee housing areas.

Determination: The Superintendent has determined the need for fires to be contained within NPS designated fire receptacles to prevent unintentional wildfire ignitions. If seasonal restrictions are implemented on the use of fires within NPS designated fire receptacles, the Superintendent has determined this process as the least restrictive means to manage their use. Any seasonal restrictions are implemented to protect park resources and the public from unintentional wildfire ignitions.

• Except when seasonal fire restrictions have been established by the Superintendent, fires contained within a commercially manufactured grill are permitted in all park areas.

Determination: The Superintendent has determined the need for fires to be contained within commercially manufactured charcoal grills to prevent unintentional wildfire ignitions. If seasonal restrictions are implemented on the use of fires within commercially manufactured charcoal grills, the Superintendent has determined this process as the least restrictive means to manage their use. Any seasonal restrictions are implemented to protect park resources and the public from unintentional wildfire ignitions.

(a)(2) Use restrictions for stoves and lanterns:

• Except when seasonal fire restrictions have been established by the Superintendent, the use of stoves and lanterns are permitted in all park areas.
