Section II: 36 CFR § 1.5 Closures and Public Use Limits

(a)(1) Establish, for all or a portion of a park area, a reasonable schedule of visiting hours, impose public use limits, or close all or a portion of a park area to all public use or to a specific use or activity.

SA 1. Boyd Pit Shooting Range.

(a) For the purposes of this part, Boyd Pit shooting range means all areas within 100 yards north and south of the target line and 125 yards west of the administrative road servicing the area.
(b) The shooting range and associated administrative road is closed to all public access.

Determination: The shooting range is designated only for use by law enforcement officers for training and administrative activities and is managed by the park’s Chief Ranger. As such, the Superintendent has determined this closure is necessary to maintain public safety and avoid conflicts between use in the area as it is used for the purposes of law enforcement firearms training. The area is signed and a map is provided in the appendices.

SA 2. Bird Nesting Closures.

(a) Peregrine Falcons.
1. (1) Annually, from March 1 through August 15, all cliff faces and surrounding lands within the following described areas or as otherwise identified by signs, maps in this document, or on-site postings, are closed to all public access:
  1. (i) The North Ridge of Champlain Mountain and the Precipice Wall, including the Precipice Trail and Orange and Black Path, bounded as follows:
    1. 1. The closure extends from the point where the Park Loop Road intersects the Orange and Black Path, then continues along the external boundary of the Park Loop Road to a straight line boundary located at UTM Northing 491024.6 meters. From that point, the closure follows a straight line between the Champlain South Ridge Trail and the Park Loop Road at UTM Northing 4910924.6 meters.
    2. 2. The closure then follows the Champlain Ridge Trails, beginning at the intersection of the straight line boundary at UTM Northing 491024.6 meters with the Champlain South Ridge Trail, and continuing to the intersection of the Champlain North Ridge Trail with the Orange and Black Connector Trail.
    3. 3. The closure further includes the Orange and Black Path and Orange and Black Connector, from their intersection with the Champlain North Ridge Trail to their intersection with the Park Loop Road.
  2. (ii) Saint Sauveur Mountain and the Valley Peak Wall, including the Valley Cove trail, bounded as follows:
    1. 1. The point where the Valley Peak Trail intersects the Valley Cove Trail, extending from that intersection in a straight line down to the waterline.
    2. 2. From this point at the coastline, the closure continues along the shoreline to the area where the Valley Cove Trail intersects the north side of the Flying Mountain Trail.
    3. 3. From that intersection, the closure follows the Valley Cove Trail southward to its intersection with the Valley Peak Trail.
    4. 4. From that intersection, the closure continues along the full length of the Valley Peak Trail back to the original intersection of the Valley Cove Trail and Valley Peak Trail at the northern boundary.
  3. (iii) Jordan Cliffs, including the Jordan Cliffs Trail, bounded as follows:
    1. 1. From the northern boundary at UTM Northing 4909422.5 meters, the closure extends south along the carriage road on the west side of Jordan Pond to Carriage Road Intersection 14.
    2. 2. From Intersection 14, the closure proceeds west along the carriage road to its intersection with the Spring Trail.
    3. 3. From that point, the closure follows the Spring Trail to its intersection with the Penobscot Mountain Trail, then continues along the Penobscot Mountain Trail to the intersection with the Penobscot East Trail.
    4. 4. The boundary then continues northward, returning to the UTM Northing 4909422.5 meter line.
  4. (iv) Echo Lake Cliffs bound as follows:
    1. 1. Beginning at N44.320531°, W 68.341061°, east along the natural drainage to N44.320218°, W 68.338202°. From this point, the shoreline of Echo Lake southward to a point located directly beneath the first switchback of the Beech Cliff Trail, defined as a straight line projection from the switchback down to the waterline.
    2. 2. From that point, the boundary runs west along the Beech Cliff Trail to its intersection with the Canada Cliffs Trail.
    3. 3. The boundary then continues around the eastern edge of the Beech Cliff Loop Trail to the crest of the ridge.
    4. 4. From the ridge crest, the boundary proceeds north along the ridgeline back to the starting coordinate at N44.320531°, W 68.341061°.

Determination: The Superintendent has determined that this closure is necessary to protect Peregrine Falcons, a state-listed endangered species, while breeding. The cliffs are used for nesting and rearing the young fledglings. Peregrine Falcons are very sensitive to human disturbance near nesting sites. Closures have been established to best protect breeding Peregrine Falcons while still allowing visitor access and recreation. Additionally, these closures have been established with federal and state wildlife management agency recommendations.

(b) Bald Eagles.
1. (1) Annually, from February 15 through August 31, the following lands are closed to all public access:
  1. (i) Bar Island in Somes Sound.
  2. (ii) Rolling Island.
  3. (iii) Sheep Porcupine Island.
  4. (iv) Long Porcupine Island.

Determination: The Superintendent has determined that this closure is necessary to protect Bald Eagles while breeding. These islands are identified in the Protected Area Management subzone of the Acadia National Park General Management Plan (GMP) or in the Schoodic General Management Plan/Environmental Impact Statement. These plans state island subzones merit the highest protection and should be managed for minimal or no human intrusion. Additionally, these closures have been established with federal and state wildlife management agency recommendations, as well as in accordance with the Bald and Golden Eagle Protection Act to prevent take.

(c) Seabirds.
1. (1) Annually, from April 1 through July 31, the following lands are closed to all public access:
  1. (i) Heron Island.
  2. (ii) Thrumcap Island.
2. (2) Annually, from February 15 to August 31, the following lands are closed to all public access:
  1. (i) Schoodic Island.

Determination: The Superintendent has determined that this closure is necessary to protect nesting seabirds while breeding. These islands are identified in the Protected Area Management subzone of the Acadia National Park General Management Plan (GMP) or in the Schoodic General Management Plan/Environmental Impact Statement. These plans state island subzones merit the highest protection and should be managed for minimal or no human intrusion. Additionally, these closures have been established with federal and state wildlife management agency recommendations.

(d) Loons.
1. (1) Annually, from March 15 to August 15, the following lands are closed to all public access:
  1. (i) Rum Island in Long Pond.

Determination: The Superintendent has determined that this closure is necessary to protect loon nesting areas. This island is identified in the Protected Area Management subzone of the Acadia National Park General Management Plan (GMP) or in the Schoodic General Management Plan/Environmental Impact Statement. These plans state island subzones merit the highest protection and should be managed for minimal or no human intrusion. Additionally, these closures have been established with federal and state wildlife management agency recommendations.

(e) Bird nesting activities will be monitored by park staff, and closures will be adjusted based on nesting success or failure as follows:
1. (1) If nesting is successful and a closure must extend beyond the prescribed timeframe identified in any paragraph of this part, the Superintendent will extend the closure by issuing an additional seasonal closure notice.
2. (2) If nesting is unsuccessful at any location identified in this part, the public will be notified as appropriate in accordance with 36 CFR §1.7, including through the removal of closure signs.

Determination: The Superintendent has determined that the provisions of this section addressing bird nesting are necessary to protect nesting birds and their habitat while providing for appropriate public access and use of park areas. Because nesting activity, success, and the timing of nesting may vary by species and location, monitoring and adjusting closures based on nesting conditions allows the park to respond to current resource conditions. Extending closures when nesting remains active or successful helps minimize disturbance during sensitive nesting periods, while removing or adjusting closures when nesting is unsuccessful or no longer occurring avoids unnecessary restrictions on public access and use. These provisions therefore provide a reasonable and adaptive means of balancing the protection of park resources with opportunities for public access and enjoyment.

SA 3. 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 this closure is necessary for public and employee safety, as well as resource protection.

SA 4. Road Closures.

(a) Seasonal.
1. (1) On a seasonal basis, motor vehicles are prohibited on the following roads:
  1. (i) Bubble Pond Parking Area – when the Island Explorer Shuttle is operational.
  2. (ii) Thompson Island Picnic Area – December 1 to April 16.
  3. (iii) Bear Brook Picnic Area – October 15 to May 14.
  4. (iv) Pretty Marsh Picnic Area – October 21 to May 26.
  5. (v) Carroll Homestead – October 21 to May 7.
  6. (vi) Blackwoods Campground Road – October 19 to May 1.
  7. (vii) Fish House Road – December 1 to April 15.
  8. (ix) Park Loop Road, except the section between the Entrance Station at Schooner Head Road and the intersection with Otter Cliff Road at Fabbri Picnic area – December 1 to April 15.
  9. (x) All Gravel Roads – November 15 to May 15.
  10. (xi) Seawall Campground Road – October 12 to May 20.
  11. (xii) Lake Wood Pond Road – October 15 to June 1.
  12. (xiv) Wildwood Stables Road – December 1 to May 29.

Determination: The Superintendent has determined that these sites are closed in the off-season to significantly decreased visitor demand, staffing limitations, no trash collection, and no cleaning staff. Buildings are closed for the winter because of the potential for freeze damage and due to operational costs associated with winter use.

(b)Time of Day.
1. (1) When roads are not seasonally closed, motor vehicles are prohibited on the following roads from one hour after sunset until one hour before sunrise:
  1. (i) Lighthouse Road and the Bass Harbor Head Light Station Parking Area.
  2. (ii) Carroll Homestead Road and Parking Area.
  3. (iii) Lake Wood Pond Road and Parking Area.
  4. (iv) Thompson Island Picnic Area.

Determination: The Superintendent has determined that these closures are necessary to deter underage drinking, vandalism, damage to park resources, disorderly conduct, and out of bounds camping. Additionally, Bass Harbor Head Light Station services as a residence.

(c) Year-round.
1. (1) Motor vehicles are prohibited on the following roads:
  1. (i) Administrative (service) roads, including the areas they provide access to.
  2. (ii) Duck Brook Road, between the Duck Brook Carriage Road Bridge and West Street Extension.
  3. (iii) Hio Fire Road.
  4. (iv) Marshall Brook Fire Road.
  5. (v) Duck Harbor Road.
  6. (vi) Western Head Road.
(d) Cadillac Summit Road.
1. (1) Closed seasonally to all motor vehicles:
  1. (i) December 1 to April 15.
2. (2) Open to all motor vehicles:
  1. (i) April 15 to May 19.
  2. (ii) October 26 to December 1.
3. (3) Vehicle Reservation System.
  1. (i) From May 20 to October 25, Cadillac Summit Road is managed by a vehicle reservation system. During this time, the following are prohibited:
    1. 1. Motor vehicles, except for commercial taxis, rideshare services and vehicles with a valid reservation permit.
    2. 2. All motor vehicles after 9:00 pm until the start of the valid reservation permit the following day.

Determination: The Superintendent has determined that these closures and use restrictions are necessary because historic vehicle congestion on this road system interferes with public safety access and visitor egress. Vehicle congestion causes routine traffic backups which lead to both cultural and natural resource damage. The reservation system was implemented to manage vehicle access to match the designated parking spaces available along the road and at the summit. The reservation system was also implemented to enhance the visitor experience. Vehicle reservations are available through recreation.gov.

SA 5. Sand Beach Sand Dunes.

(a) For the purposes of this part, Sand Beach Sand Dunes means the area between Sand Beach, which is part of Newport Cove, and the Beehive Lagoon where a natural accumulation of sand has been formed into mounds or ridges and has been cordoned off by means of a rope or other barrier.
(b) Sand Beach Sand Dunes are closed to all public access.

Determination: The Superintendent has determined this closure is necessary to protect dune grasses and sensitive park resources that are negatively impacted by human disturbance.

SA 6. Liscomb Pit.

(a) For the purposes of this part, Liscomb Pit means all developed or disturbed areas at the terminus of Liscomb Pit Road.
(b) Liscomb Pit is closed to all public access.

Determination: The Superintendent has determined this closure is necessary to improve security for park assets stored in the area. Additionally, the area has historically been and is still maintained as a gravel pit which presents a concern for public safety between ongoing maintenance operations and unstable ground.

SA 7. Hulls Cove Storage.

(a) For the purposes of this part, Hulls Cove Storage means all facilities and developed areas at the terminus of the administrative road accessed off Hulls Cove Road.
(b) Hulls Cove Storage is closed to all public access.

Determination: The Superintendent has determined this closure is necessary to preserve park staff access as the area is to conduct administrative activities. Additionally, equipment and supplies essential to the orderly management of the park are stored in the area and heavy equipment is frequently present, lifting and moving supplies.

SA 8. Employee Housing.

(a) For the purposes of this part, employee housing means all facilities, campgrounds or campsites used to house or service government or park concession employees, including all developed or disturbed ground immediately surrounding or adjacent to.
(b) Employee housing is closed to all public access.

Determination: The Superintendent has determined this closure is necessary to improve security and privacy to residents while not adversely impacting park visitors. This closure does not include legitimate park business or resident activities as outlined in the park’s Housing Management Plan.

SA 9. Public Use Limits.

(a) The following public use limits have been established for Mount Desert Island:
1. (1) Organized groups are limited to 20 individuals on:
  1. (i) Trails.
  2. (ii) Carriage Roads.
  3. (iii) Road Corridors.
2. (2) Organized, stationary events are limited to 30 individuals.
(b) The following public use limits have been established for Schoodic Peninsula:
1. (1) Organized groups are limited to 15 individuals on:
  1. (i) Trails.
  2. (ii) Bike Paths
  3. (iii) Road Corridors.
2. (2) Organized, stationary events are limited to 30 individuals.
(c) Organized groups are limited to 8 individuals on Isle au Haut.
(d) Except as provided in this section, any group or event with individuals exceeding these established limits are required to have a special use permit:
1. (1) School Groups with Educational Fee Waivers. A school group that has been approved for an educational fee waiver by Acadia National Park is not required to obtain a Special Use Permit solely because the group exceeds the applicable group-size limit when the group is located within a road corridor or developed area. This exception only applies to group size restrictions within the road corridor or developed areas and does not authorize a group to exceed established group-size limits on trails, carriage roads, or bike paths. When a school group with an approved Educational Fee Waiver uses a trail, carriage road, or bike path, the applicable group-size limit remains in effect, and groups exceeding that limit must obtain a Special Use Permit.

Determination: Group Size limits were established to ensure that all visitors maintain equal access to the park. Larger group sizes cause congestion on trails, fill parking lots and impact other visitors to Acadia. Schoodic and Isle au Haut group sizes are smaller due to the separate management plans that focus on providing solitude and a wilderness experience. School groups are exempt from some of these group size limitations as they already obtain an educational fee waiver, which provides an opportunity to coordinate with park staff about their park visits. Further, NPS wishes to facilitate educational access for children to the park, while retaining group size limits for trails, carriage roads and bike paths.

SA 10. The Bear Island Lighthouse and associated land on Bear Island is closed to all public access.

Determination: The National Park Service owns the Bear Island Lighthouse which encompasses 2 acres of land. The Superintendent has determined this closure is necessary because the lighthouse is administered under a historic lease that prohibits public access. As an additional note, the remainder of Bear Island is privately owned.

SA 11. All public water supply tanks or towers, including a radius of 100 feet from the center of the tower, are closed to all public access.

Determination: The Superintendent has determined this closure is necessary to protect water used for public consumption in the park.

SA 12. All buildings and fenced areas at Bass Harbor Head Light Station are closed to all public access.

Determination: The Superintendent has determined this closure is necessary because they are utilized by park staff working or accessing the buildings for administrative purposes. Additionally, areas within this closure pose serious safety risks at cliff edges

SA 13. The building and enclosure for the Cadillac Repeater Tower on the Summit of Cadillac Mountain is closed to all public access.

Determination: The Superintendent has determined this closure is necessary to protect essential park infrastructure which, if compromised or damaged, would be costly to repair and impact life safety responses.

SA 14. The observation cab and adjacent walkway of the Beech Mountain Fire Tower are closed to all public access.

SA 15. On an annual basis, during spring thaw, all carriage road segments and areas providing access thereto shall be closed to all public use for the duration of the thaw period.

Determination: The Superintendent has determined this closure is necessary because the carriage road system is susceptible to damage by public use during the seasonal thaw periods over the spring months. During these periods, affected segments and access areas will be marked on site with signage, as well as through other official channels.

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

(e) Lower Hadlock Pond.

SA 4. The Duck Harbor Dock is closed to the mooring of all vessels, except that dinghies are permitted to tie up on the south side of the dock.

SA 5. Anchoring or tying any vessel to the shore is prohibited, except when a person is present and directly attending the vessel.

Determination: The Superintendent has determined this closure is necessary to protect park resources from damage and avoid user conflicts, as well as obstruction to other visitor activities.

Wildlife Protection

SA 6. 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.

SA 7. To protect park wildlife, the following are prohibited:

(a) Willfully approaching, remaining, viewing or engaging in any activity:
1. (1) Within 25 yards of any wildlife, except bears or when completely inside a legally positioned motor vehicle.
2. (2) Within 50 yards of bears, except when completely inside a legally positioned motor vehicle.
3. (3) Within any distance that displaces or interferes with the free unimpeded movement of any wildlife.
4. (4) Within any distance that creates or contributes to a potentially hazardous condition or situation.
5. (5) Failing to remove oneself to prescribed distances during inadvertent, accidental or surprise encounters with wildlife.

Determination: The Superintendent has determined that these public use restrictions and requirements are necessary to maximize public safety, protect wildlife, and provide park staff with the flexibility to situationally manage dynamic, diverse and rapidly evolving wildlife viewing opportunities.

Rock Climbing

SA 8. The development of new climbing routes, which includes route cleaning and bolt or piton use, is prohibited without written authorization from the Superintendent.

Determination: The Superintendent has determined this restriction is necessary for implementation of the park’s Climbing Management Plan, which was created in 1997, to prevent negative impacts on park resources and quality visitor experiences. In the Climbing Management Plan, routes are limited to specific areas, and any new development requires authorization from the Superintendent.

SA 9. All climbing groups are limited to 12 individuals, including guides.

Determination: The Superintendent has determined this restriction is necessary to prevent negative impacts to park resources and quality visitor experiences. Additionally, this group size restriction has been established in the parks Climbing Management Plan which was created in 1997.

SA 10. Between Memorial Day and Columbus Day, climbing groups of six individuals or larger, including guides, must obtain a special use permit.

Determination: The Superintendent has determined a permit is required during these time periods to avoid multiple groups from arriving on the same day and prevent negative impacts to park resources and quality visitor experiences.

General Park Use

SA 11. Launching, landing, or operating an uncrewed or remotely piloted aircraft from or on lands and waters administered by the National Park Service within the boundaries of Acadia National Park is prohibited except as approved in writing by the Superintendent.

Determination: This restriction is necessary to prevent unacceptable impacts to park resources and values from the use of uncrewed aircraft. Potential impacts include harming visitors, interfering with rescue operations, causing excessive noise, impacting viewsheds, and disturbing wildlife. This restriction is required by NPS Reference Manual #60: Aviation Management, Chapter 12 – Uncrewed Aircraft Systems.

SA 12. Idling an engine or motor vehicle is prohibited, except for the Island Explorer shuttle system and:

(a) While stopped in traffic or a construction line.
(b) While actively loading or unloading passengers.
(c) While warming up a motor vehicle’s engine for no longer than 10 minutes in developed areas or parking lots.

Determination: Idling engines and motor vehicles produce noise and noxious fumes that adversely affect air quality, park resources, and visitor health and experience. The Superintendent has established these conditions to protect park resources, promote better air quality in the park, protect and enhance visitor experience. These conditions have been determined as the least restrictive means to ensure operators can still warm up engines or motor vehicles for optimum use and to heat and cool motor vehicle interiors for passenger comfort without negatively impacting park resources and the public.

SA 13. It is prohibited to leave or confine a pet in an unattended motor vehicle under conditions that endanger the health or well-being of a pet due to heat, cold, lack of adequate ventilation, or lack of food or water, or other circumstances that could reasonably be expected to cause suffering, disability, or death to the pet.

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

SA 14. Filming, still photography, and audio recording activity may require a permit consistent with 54 USC 100905.

(a) Filming, still photography, and audio recording activity that occurs in closed areas, requires exclusive use of a site or area, or involves a set or tagging equipment other than handheld equipment (such as a tripod, monopod, and handheld lighting equipment) requires a permit, unless the activity is affiliated with an activity or event that has been allowed under written authorization, such as a special use permit.
(b) Filming, still photography, and audio recording that involves more than eight individuals requires a permit, unless the NPS has specifically notified an individual or group that a permit is not required, or if the activity is affiliated with an activity or event that has been allowed under written authorization, such as a special use permit.
(c) If a permit is required for the reasons stated above, or if the NPS otherwise determines and then notifies an individual or group that a permit is required for a filming, still photography, or audio recording activity, then engaging in that activity without a permit is prohibited. Violating a term or condition of a permit issued by the NPS for a filming, still photography, or audio recording activity is prohibited, and may result in the suspension or revocation of the permit, in addition to any penalties that may apply under 36 CFR 1.3.

Determination: Federal law at 54 USC 100905 states that permits and fees are not required for filming, still photography, or audio recording in park areas if certain requirements are met. These requirements address various topics, including, but not limited to, group size, location, equipment, potential impacts to resources and visitors, and the likelihood that the NPS will incur related administrative costs. If any of these requirements are not met, the law allows the Secretary of the Interior, acting through the NPS , to require a permit for the subject activity. Permit requirements are imposed by the Superintendent under discretionary authority provided by 36 CFR 1.5(a)(2), which allows the Superintendent to impose conditions or restrictions on a use or activity, consistent with applicable legislation, to implement management responsibilities. The imposition of permit requirements, on a case-by-case basis, for filming, still photography, or audio recording does not require rulemaking under 36 CFR 1.5(b). Requiring a permit with reasonable terms and conditions in accordance with statutory requirements at 54 USC 100905 is not highly controversial, will not result in a significant alteration in public use patterns of the System unit, will not adversely affect the System unit’s natural, aesthetic, scenic or cultural values, or require a long-term or significant modification in the resource management objectives of the System unit, because the permit requirement is limited in time and scope to the specific activities authorized by the permit, which contain terms and conditions that protect the values, resources, and visitors of the System unit, and implements federal law.

SA 15. All commercial use is prohibited within the park on Isle au Haut.

Determination: The Superintendent has determined this restriction is necessary to support Isle au Haut planning documents, which state all commercial use, except visitor delivery service to Duck Harbor which is provided by the Isle au Haut boat services, are prohibited. In the Isle au Haut Visitor Use Management Plan, which was established in 2014, it states, “no commercial uses are allowed on NPS lands on Isle au Haut.” In the Commercial Services plan, which was established in 2000, it states, “other commercial operations will continue to be excluded from the Isle au Haut section of Acadia National Park.”

SA 16. The use of electronic nicotine delivery systems (ENDS) is prohibited in the following areas, buildings, structures or facilities:

(a) All interior spaces and outdoor areas within 25 feet of air intake ducts, including doors and windows, of buildings owned, rented or leased by the federal government.
(b) The fenced enclosures, known as the Wild Gardens of Acadia, located at Sieur de Monts.
(c) Campground amphitheaters.
(d) Bus shelters or within 25 feet of a bus stop while the shuttle is running.

Determination: The Superintendent has determined this restriction aligns with Policy Memorandum 15-03 which calls to treat ENDS in the same manner as smoking. This means Directors Order 50D, which provides guidelines to park managers to address smoking in a park area, applies to ENDS.

Section III: 36 CFR § 1.6 Permits

(a) When authorized by regulations set forth in this chapter, the superintendent may issue a permit to authorize an otherwise prohibited or restricted activity or impose a public use limit.

Section IV: General 36 CFR Regulations

Part 2 - Resource Protection, Public Use and Recreation

36 CFR §2.1 - Preservation of Natural, Cultural, and Archeological Resources:

(a)(4) Designated areas where dead wood on the ground may be collected for use as fuel for campfires within the park area:

SA1. In developed areas and along park roads open to the public up to 100 feet from the edge of the roadway or developed area.

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

(a)(5) Designated areas and conditions for walking on, climbing, entering, ascending, descending, or traversing an archeological or cultural resource, monument, or statue:

No areas or conditions have been designated as an exception to this prohibition.

(b) Restrictions for hiking or pedestrian use to designated trail or walkway systems:

SA1. Foot travel is restricted to designated trails and walkway systems when traveling through signed or cordoned off revegetation and restoration areas.

Determination: Revegetation and restoration efforts are an important function of the NPS. Revegetation and restoration is an attempt to get an area of the park back to baseline condition before a certain event or use causes unacceptable resource impacts. To successfully restore a park area back to baseline takes significant planning and effort for NPS staff. The Superintendent has determined this restriction is necessary and the least restrictive means to prevent further unacceptable resource impacts and provide an opportunity for successful revegetation and restoration attempts.

(c)(1) Designated fruits, berries, nuts, or unoccupied seashells that may be gathered for personal use or consumption within the park.

SA1. The following may be gathered by hand for personal use or consumption:

(a) All fruits.
(b) All berries.
(c) All nuts.
(d) All unoccupied seashells.

(c)(2)(i) Size and quantity limits for designated fruits, berries, nuts, and unoccupied seashells.

SA1. The following are size and quantity limits for designated fruits, berries, nuts, and unoccupied seashells:

(a) Fruits, except apples.
1. (1) No size limit.
2. (2) One, dry half gallon per person, per day and in possession.
(b) Apples.
1. (1) No size limit.
2. (2) Ten, dry half gallons per person, per day and in possession.
(c) Berries.
1. (1) No size limit.
2. (2) One, dry half gallon per person, per day and in possession.
(d) Nuts.
1. (1) No size limit.
2. (2) Unshelled - one, dry half gallon per person, per day and in possession.
(e) Unoccupied seashells.
1. (1) No size limit.
2. (2) One, dry pint per person, per day and in possession.

(c)(2)(ii) Location limits for the gathering of natural products.

SA1. Aside from park areas which are closed to public access, there are no location limits for the gathering of fruits, berries, nuts, and unoccupied seashells.

(c)(2)(iii) Possession and consumption restrictions.

SA1. The possession or consumption of fruits, berries, nuts, and unoccupied seashells is not restricted to park areas.

Determination: The Superintendent has determined all parts of section (c) have been determined to allow generous personal collection and consumption while not adversely affecting park resources as they relate to fruits, berries, nuts, and unoccupied seashells.

36 CFR §2.2 - Wildlife Protection.

(d) Conditions and procedures for transporting lawfully taken wildlife through the park area:

SA1. It is prohibited to retrieve wounded or dead wildlife that travels into the park after an attempt to take the animal occurred outside park boundaries without authorization from the Superintendent.

Determination: The Superintendent has determined this condition is necessary because hunting is prohibited within Acadia National Park. The requirement of a permit allows the Superintendent to set appropriate procedures for retrieving wounded or dead wildlife when a lawful attempt to take occurred outside the park to allow proper investigation that protects both individuals and wildlife within the park.

(e) Park areas closed to the viewing of wildlife with an artificial light:

SA1. The entire park is closed to viewing wildlife with artificial light.

Determination: The Superintendent has determined this closure is necessary to protect wildlife from disturbance, prevent disruption of natural behaviors, and preserve ecological integrity.

36 CFR §2.3 - Fishing.

(d)(2) Waters designated for the possession and use as bait for fishing in fresh waters, live or dead minnows or other bait fish, amphibians, nonpreserved fish eggs or roe.

SA1. The waters listed below are designated for the possession and use of bait. These waters remain subject to special fishing regulations established by the State of Maine, including seasonal and date-specific restrictions:

(a) Aunt Betty Pond.
(b) Bubble Pond.
(c) Eagle Lake.
(d) Jordan Pond.
(e) Lake Wood.
(f) Upper Hadlock Pond and Tributaries.

Determination: The Superintendent has determined this designation only applies to Great Ponds. Great Ponds were created as part of a Colonial Ordinance before the State of Maine was established. Upon the establishment of the State of Maine, Great Ponds were written into law to protect access for the purposes of recreation, namely fishing and hunting. Where statutory and federal law allows, the Superintendent finds it important to work with the State of Maine to allow for and protect the same so long as it is not in derogation of the National Park Service mission.

(d)(8) Designated areas as an exception to the prohibition of fishing from motor road bridges, from or within 200 feet of a public raft or float designated for waters sprots, or within the limits of locations designated as swimming beaches, surfing areas, or public boat docks.

No areas have been designated as an exception to this prohibition.

36 CFR §2.10 - Camping and Food Storage.

(a) Permits, designated sites or areas, and established conditions for camping:

Designated Areas for Camping

SA1. The following areas have been established for camping within the park:

(a) Blackwoods Campground.
(b) Seawall Campground.
(c) Schoodic Woods Campground.
(d) Duck Harbor Campground.
(e) Wildwood Stables Campground.

Camping Permit Requirements

SA2. A camping permit is required to stay overnight in the areas established in (a)(SA1) of this section.

Determination: The Superintendent has determined this is necessary to ensure that overnight use is properly authorized, facilitate management of campground capacity, and maintain accountability for resource protection. Campground permits can be obtained at recreation.gov, except for Wildwood Stables Campground which is managed by Acadia by Carriage, LLC.

Camping Conditions

SA3. Check-out Times.

(a) Campsites must be packed up and vacated by 10:00 am at the following campgrounds:
1. (1) Blackwoods
2. (2) Seawall
3. (3) Schoodic Woods
4. (4) Wildwood Stables
(b) Campsites must be packed up and vacated by 11:00 am at the following campgrounds:
1. (1) Duck Harbor

Determination: The Superintendent has determined these are necessary to allow sufficient time for site turnover, cleaning, and maintenance, and to ensure timely availability for incoming campers. Check-out is required by 10:00 am at Blackwoods, Seawall, Schoodic Woods, and Wildwood Campgrounds, and by 11:00 am at Duck Harbor Campground.

SA4. Camping Limits.

(a) Length of Stay.
1. (1) Camping is limited to a maximum of 14 nights per person from the Friday before Memorial Day weekend through Colombus Day.
2. (2) Camping is limited to a maximum of 30 nights per person within a calendar year.
3. (3) Camping at Duck Harbor Campground is limited to a maximum of three nights per person within a calendar year.

Determination: The Superintendent has determined camping duration limits are established to protect natural resources, prevent long-term or residential use of campsites, manage peak-season demand, and ensure equitable public access. The 14 night per person limit during the peak season is necessary to address high visitor demand, reduce cumulative resource impacts, and promote campsite availability. The 30 night per person annual limit prevents extended occupancy, supports campsite turnover, and minimizes environmental and infrastructure impacts associated with repeated use. The three night per person annual limit at Duck Harbor Campground is required due to limited capacity, sensitive resources, and access constraints, and to ensure fair access to this location.

(b) Party Size.

1) Camping is limited to six people per campsite, except group campsites.

(2) Group campsites at Blackwoods Campground and Seawall Campground are limited to a maximum of 15 people per site.

(3) Group campsites at Schoodic Woods Campground are limited to a maximum of 20 people per site.

Determination: The Superintendent has determined campsite occupancy limits are established to protect natural resources, prevent overcrowding, ensure visitor safety, and maintain the intended recreational character of campground facilities. The six-person limit for standard campsites reflects site design and infrastructure capacity, while higher limits for group campsites—15 people at Blackwoods and Seawall Campgrounds and 20 people at Schoodic Woods Campground—are based on site-specific design, facilities, and capacity to accommodate increased group use without unacceptable impacts.

(c) Tents.
1. (1) Vehicle accessible campsites at Blackwoods Campground and Seawall Campground are limited to a maximum of two tents and one vehicle per site.
2. (2) Vehicle accessible campsites at Schoodic Woods Campground are limited to two tents and two vehicles per site.
3. (3) Tents may only be set up on designated, prepared tent pads and compacted soil areas of the campsite, except for Duck Harbor Campground.
4. (4) Tents at Duck Harbor Campground are limited to those that fit within the shelter provided.
5. (5) Hammocks are not considered a tent and are prohibited in all areas designated for camping.

Determination: The Superintendent has determined limits on tents, vehicles, and camping equipment are established to protect natural resources, prevent overcrowding, maintain site functionality, and ensure visitor safety. Restrictions on the number of tents and vehicles at vehicle-accessible campsites reflect campground design, parking capacity, and circulation needs, with site-specific allowances at Schoodic Woods Campground based on its larger site layout. Requirements that tents be placed only on designated pads or compacted soil areas, and that tents at Duck Harbor Campground fit within provided shelters, are necessary to prevent vegetation damage, soil compaction, and resource degradation. The prohibition on hammocks within designated camping areas is intended to prevent resource damage and conflicts with campsite design and use.

(d) Generators.
1. (1) The operation of generators within designated camping areas is prohibited, except in the following locations:
  1. (i) Loop A of Blackwoods Campground.
  2. (ii) Loop C of Seawall Campground.
2. (2) Where permitted, the operation of generators is restricted to the following time frames:
  1. (i) 8:00 am to 10:00 am.
  2. (ii) 4:00 pm to 7:00 pm.
3. (3) While a generator is operating, the campsite must be occupied.

Determination: The Superintendent has determined generator use restrictions are established to minimize noise impacts, protect visitor experience, and ensure safe and appropriate use within campground settings. The prohibition of generators in designated camping areas, with limited exceptions in Loop A of Blackwoods Campground and Loop C of Seawall Campground, reflects site-specific capacity to accommodate generator use without unreasonable disturbance. Time-of-day restrictions are necessary to limit noise during quiet hours and reduce conflicts between users, and the requirement that campsites be occupied while a generator is operating ensures active supervision and compliance.

(e) Camping at Wildwood Stables Campground is limited to people with stock or pack animals only.
(f) Vehicles are restricted to the campsite’s designated parking area, which may consist of paved surfaces, compacted soil, gravel, or woodchips.
(g) The use of dump stations in all areas designated for camping is limited to persons with a valid camping permit.
(h) Bug and string lights are prohibited in all areas designated for camping.
(i) Slacklines and other similar tension-line devices are prohibited in all areas designated for camping.
(j) Portable showers and toilets are prohibited in all areas designated for camping.

Determination: The Superintendent has determined these special use and equipment restrictions are established to protect natural resources, maintain campground character, and ensure safe and orderly use of facilities. Limiting camping at Wildwood Stables Campground to persons with stock or pack animals preserves the campground’s intended purpose and accommodates its design and resource conditions. Restrictions on vehicle placement confine use to hardened surfaces to prevent soil disturbance and vegetation damage. Limiting dump station use to permitted campers ensures proper capacity management and sanitation. Prohibitions on bug and string lights, as well as portable showers and toilets, are necessary to reduce wildlife impacts, visual intrusion, sanitation concerns, and infrastructure conflicts. Slacklines and other similar tension-line devices are prohibited to prevent repeated use in a highly concentrated area and otherwise prevent damage to trees.

(d) Food storage conditions:

SA1. The following definitions, established by the Superintendent, apply to the food storage restrictions listed in this section:

(a) 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.
(b) 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 BRFCs; 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 become food conditioned. The Superintendent has determined these definitions are necessary and considered the least restrictive means to protect park wildlife and the public.

SA2. In all park areas, food, lawfully taken fish or wildlife, garbage, and any equipment used to cook or store food must be sealed inside a vehicle, a camping unit constructed of solid, non-pliable material, or a BRFC. This requirement does not apply to park residents who are in compliance with the food storage provisions of the Acadia National Park Housing Plan, nor to established NPS grills and fire grates located 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 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 as a legal means to store food because they are constructed to prevent park wildlife from obtaining food and becoming food conditioned. The Superintendent has determined these options help prevent further restrictions on the public while protecting park wildlife and the public.

SA3. When using a BRFC for food storage, it must properly function in designed condition and be secured as prescribed by the manufacturer.

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 bears. The Superintendent has determined these are the least restrictive means to protect park wildlife and the public.

36 CFR §2.11 - Picnicking.

SA1. Picnicking is prohibited in areas designated for camping.

Determination: The Superintendent has determined prohibiting picnicking in areas designated for camping is necessary to prevent conflicts between day-use and overnight visitors, reduce overcrowding, and protect campground resources and facilities intended for overnight use.

36 CFR §2.13 - Fires.

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

SA 1. 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, and commercially manufactured grills in the following locations:

(a) Campgrounds.
(b) Picnic areas.
(c) Park 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.

SA 2. Except within buildings or when seasonal fire restrictions based on local fire danger ratings have been established by the Superintendent, fires contained within commercially manufactured gas and charcoal grills are permitted in all park areas.

SA 3. Where permitted, a fire may be ignited and maintained only by using fuel sources designed and commonly used for warmth or the preparation of food, such as charcoal briquettes or natural firewood. Lighting or maintaining a fire with other materials including, but not limited to, flammable liquids, garbage, fireworks, plastics, aerosol canisters, batters, or other manufactured or synthetic materials, is prohibited.

Determination: This action is necessary for the maintenance of public health and safety, protection of environmental or scenic values, protection of natural or cultural resources, and the implementation of management responsibilities. Materials other than approved combustibles – especially fire accelerants and substances prone to wind transport or explosion – create serious risks when used to light or maintain fires. These combustibles can ignite or spread wildfires that directly threaten people and valuable resources and assets. The burning of manufactured or synthetic materials can contribute to air pollution, contaminate soil and water, and be toxic to humans and the environment. Less restrictive measures, such as education campaign, would not be commensurate with the substantial risks associated with those activities and could lead to adverse outcomes that might be prevented by establishing an enforceable condition.

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

SA1. Except when seasonal fire restrictions have been established by the Superintendent, the use of stoves and lanterns are permitted in all park areas.

Determination: The Superintendent has determined no restrictions are necessary for the use of stoves and lanterns unless seasonal weather and fire danger dictate otherwise. If seasonal restrictions are implemented, the Superintendent has determined this process as the least restrictive means to manage the use of stoves and lanterns. Any seasonal restrictions are implemented to protect park resources and the public from unintentional wildfire ignitions.

(b) Conditions for extinguishing fires:

SA1. Any fuel used to light and maintain a fire, including coals and remains, must be cold to touch prior to abandonment.
Determination: The Superintendent has determined that these conditions are necessary to prevent wildfire risk, protect natural resources, and ensure visitor safety.

36 CFR §2.14 - Sanitation and refuse

(a)(2) Established conditions for use of government refuse receptacles for dumping household, commercial, or industrial refuse brought as such from private or municipal property:

No conditions have been established by the superintendent.

(a)(5) Areas designated for bathing, or washing food, clothing, dishes, or other property:

SA1. Rinse kits at Sand Beach are designated solely for the purpose of rinsing off sand or dirt.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary to ensure availability for all users, prevent misuse that could impact water quality or facilities, and maintain site sanitation.

(a)(7) Designations for disposing of fish remains on land, or in waters within 200 feet of boat docks or designated swimming beaches, or within developed areas:

No designations have been established by the Superintendent.

(a)(9) Designations for disposal of human body waste in nondeveloped areas:

No designations have been established by the Superintendent.

(b) Human body waste conditions:
SA1. In all nondeveloped areas, human waste must be buried in a hole at least six inches deep and in coordination with the requirements listed in §2.14(a)(9).

Determination: The Superintendent has determined these prohibitions and restrictions are necessary to protect water quality, prevent the spread of disease, and minimize environmental impacts.

SA2. All toilet paper or similar material must be carried out of nondeveloped areas and disposed of in appropriate refuse receptacles.

Determination: The Superintendent has determined these prohibitions and restrictions are necessary to protect water quality, prevent sanitation hazards, and minimize environmental impacts.

36 CFR §2.15 - Pets.

(a)(1) Possession of a pet within the park:

SA1. The following areas and trails are closed to the possession of pets:

(a) The fenced enclosure, known as the Wild Gardens of Acadia, located at Sieur de Monts
(b) Beehive Trail segment extending from the junction of the Bowl Trail at the base of the Beehive to the Summit of the Beehive.
(c) Beech Cliffs Trail segment extending from the trailhead at Echo Lake to the junction with Canada Cliffs Trail.
(d) Ladder Trail segment extending from the junction with Kane Path to the junction with Schiff Path.
(e) Perpendicular Trail segment extending from the Long Pond Trail to the junction with the Mansell Mountain Trail east of the Summit of Mansell Mountain.
(f) Precipice Trail.
(g) Jordan Cliffs Trail segment extending from the junction with the Amphitheatre East Carriage Road junction to the junction with the Penobscot East Trail.
(h) The following waters:
1. (1) Eagle Lake.
2. (2) Bubble Pond.
3. (3) Jordan Pond.
4. (4) Upper Hadlock Pond.
5. (5) Lower Hadlock Pond.
(i) Areas with established closures for all public access.

Determination: The Superintendent has determined that these prohibitions are necessary because each of these trails has one or multiple areas in which a hiker must climb iron rungs or ladders. The possession of a pet on these trails or trail segments poses a hazardous condition to their pet as well as other hikers. Closing these trails to pets prevents unnecessary conflict and potential injury.

SA2. Service animals are not subject to the park’s pet policies and, when accompanying an individual with a disability, they are allowed wherever visitors are allowed.

Determination: The Superintendent has determined this necessary to align with NPS Memorandum 19-02 – Use of Service Animals by Visitors with Disabilities.

(a)(3) Designated areas or conditions for leaving a pet unattended and tied to an object:

No areas or conditions allow exceptions to this prohibition.

(a)(5) Pet excrement disposal conditions:

SA1. Pet owners or handlers must possess a suitable means to remove pet waste.

SA2. Pet owners or handlers are required to immediately remove and properly dispose of pet excrement in designated refuse receptacles or carry it out of the park.

Determination: The Superintendent has determined that these prohibitions and restrictions are necessary to protect public health, maintain sanitary conditions, prevent pollution, and minimize impacts on natural resources.

(e) Conditions for residents keeping pets:

SA1. Park residents may keep pets in accordance with Acadia National Park’s housing and pet policy.

Determination: The Superintendent has determined these conditions are necessary to align with NPS Policy Memorandum 19-02 – Use of Service Animals by Visitors with Disabilities.

36 CFR §2.16 - Horse and Pack Animals.

(a) Aside from horses, burros, and mules no other hoofed mammals have been designated as “pack animals” by the Superintendent.

(b) Trails, routes and areas designated for horses and pack animals:

SA1. Designated trails, routes or areas.

(a) The following carriage road segments are designated for horse or pack animal use:
1. (1) Junction 6 to 11.
2. (2) Junction 7 to 8.
3. (3) Junction 7 to 17.
4. (4) Junction 8 to 10s.
5. (5) Junction 10n to 11.
6. (6) Junction 10n to 12.
7. (7) Junction 10s to 10n.
8. (8) Junction 10s to 14.
9. (9) Junction 11 to 13.
10. (10) Junction 12 to 13.
11. (11) Junction 12 to 19.
12. (12) Junction 13 to 18.
13. (13) Junction 14 to 15.
14. (14) Junction 14 to 21.
15. (15) Junction 15 to 16.
16. (16) Junction 15 to 23.

19. (19) Junction 17 to 37.
20. (20) Junction 18 to 19.
21. (21) Junction 19 to 20.
22. (22) Junction 20 to 21.
23. (23) Junction 20 to 22.
24. (24) Junction 21 to 22.
25. (25) Junction 23 to 25.
26. (26) Junction 36 to 37.
27. (27) Junction 36 to 38.
28. (28) Junction 36 to Day Mountain Summit.
29. (29) Junction 38 to Junction 30 (Land and Garden Preserve).
30. (30) Brown Mountain Parking Lot to Carriage Road Entrance near Junction 18.
31. (31) Wildwood Stable Area to Carriage Road Entrance near Junction 17.

(d) Designations for free-trailing or loose-herding of horses or pack animals on trails:

No areas have been designated as an exception to this prohibition.

(g) Horse and pack animal conditions:

SA1. Disease Control

(a) Any owner or handler bringing, keeping, or utilizing an equine within park boundaries must adhere to the following health documentation mandates:
1. (1) Equine Infectious Anemia (Coggins) Test – Interstate Origin. For any equine entering the park from outside the State of Maine, the owner or handler must possess an official, legible record (original or copy) of a negative test for Equine Infectious Anemia. The test must be administered within twelve (12) months prior to the date the equine enters the park.
2. (2) Equine Infectious Anemia (Coggins) Test – Intrastate Origin. For any equine originating from within the State of Maine, the owner or handler must possess an official, legible record (original or copy) of a negative test for Equine Infectious Anemia. The test must have been administered within thirty-six (36) months prior to the date the equine enters the park.
3. (3) Certificate of Veterinary Inspection (CVI). For any equine entering the park from outside the State of Maine, the owner or handler must possess an official CVI (health certificate). This certificate must be issued by a licensed, accredited veterinarian within thirty (30) days prior to the equine’s arrival at the park.
4. (4) Inspection of Documents. The owner or handler must immediately present the documentation required under subsections (1), (2), and (3) at the request of any authorized park personnel.

Determination: The Superintendent has determined the requirement for proof of a negative Coggins test and a Certificate of Veterinary Inspection (CVI) is essential for the proper management of the park to protect public recreational resources, fulfill state agricultural mandates, and safeguard animal welfare. Equine Infectious Anemia (EIA) is a highly contagious, incurable, and blood-borne viral disease with no vaccine, often carried by asymptomatic equines and mechanically transmitted by biting insects that thrive in park trailheads, pastures, and staging areas. Because recreational trail users congregate from varied geographic regions, establishing enforceable biosecurity compliance—mirroring Maine’s 12-month interstate and 36-month intrastate agricultural health mandates—is the minimum restrictive means available to prevent catastrophic viral outbreaks, defend park visitors from massive emotional and economic loss, and ensure the long-term biological safety of the park's multi-use trail systems.

SA2. Horse and pack animal manure removal conditions.

(a) In developed areas, horse and pack animal manure must be promptly removed.
(b) On carriage roads, manure must be removed or dispersed off the road surface, except while the animal is actively being ridden or used to pull a carriage.

SA3. During seasonal thaw periods all trails, routes or areas listed in (b)(SA1)(a) of this section are closed to horses and pack animals.

Determination: The Superintendent has determined this restriction is necessary to protect trails, routes, and surrounding natural resources from damage during these time periods and to prevent the significant impacts to the park that result from repairing and restoring affected areas.

36 CFR §2.17 – Aircraft and Air Delivery.

(c)(1) Procedures for the removal of downed aircraft:

SA1. Procedures for removing downed aircraft will be created on a case-by-case basis.

36 CFR §2.18 - Snowmobiles.

Acadia National Park has promulgated special regulations designating routes and waters surfaces for snowmobile use, they can be found in 36 CFR §7.65(a).

36 CFR §2.19 - Winter Activities.

(a) Designated areas for skiing, snowshoeing, ice skating, sledding, innertubing, tobogganing and similar winter sports on park roads and in parking areas open to motor vehicle traffic:

SA1. Winter activities are permitted on the left lane of the one-way section of the Park Loop Road when sufficient snow cover exists.

Determination: The Superintendent has determined these activities are appropriate because the left lane is maintained for snowmobile and winter recreational use, while the right lane is maintained for motor vehicles. These activities do not conflict with snowmobile use and are typical of other parks and areas within the System and the State of Maine.

(b) Designated areas or routes for the towing of persons on skis, sleds, or other sliding devices by motor vehicle or snowmobile.

No areas or routes have been designated as an exception to this prohibition.

36 CFR §2.20 - Skating, Skateboards and Similar Devices.

The use of roller skates, skateboards, roller skis, roller blades or similar devices are permitted in the following areas:

SA1. Government and NPS housing areas.

SA2. Park roads when they are closed to motor vehicles.

Determination: The Superintendent has determined these activities are appropriate in these areas because the primary source of conflict and resource impact in the park is motor vehicle use. In government or NPS housing areas, motor vehicle use is limited to administrative purposes. When park roads are closed to motor vehicles, the only motor vehicle use is administrative, and these areas are suitable for skating, skateboarding, and similar devices because the road surfaces provide a safe, low-impact environment for recreational use.

36 CFR §2.21 - Smoking.

(a) Park areas, buildings, structures or facilities closed to smoking:

SA1. All interior spaces and outdoor areas within 25 feet of air intake ducts, including doors and windows, of buildings owned, rented, or leased by the federal government.

SA2. The fenced enclosure, known as the Wild Gardens of Acadia, located at Sieur de Monts

SA3. Campground amphitheaters.

SA4. Bus shelters or within 25 feet of a bus stop while the shuttle is running.

SA5. Flammable storage areas.

SA6. Fuel refilling areas.

Determination: The Superintendent has implemented this closure in accordance with Executive Order 13058 entitled “Protecting Federal Employees and the Public from Exposure to Tobacco Smoke in the Federal Workplace.” The intent of EO 13058 is to establish a smoke-free environment for federal employees and members of the public visiting or using federal facilities. Additionally, smoking in flammable storage and fuel refilling areas is inherently dangerous and poses a great threat to federal employees and the public. The Superintendent has determined this closure is necessary and the least restrictive means to provide safety measures for federal employees and the public. Additionally, DO 50D provides guidance on how smoking should be managed in park areas, to which this aligns.

36 CFR §2.22 - Property.

(a)(2) Unattended property designations and conditions:

SA1. On ponds open to fishing, a person who owns a shack or other temporary structure used for ice fishing may leave the structure in place longer than 24 hours, under the following conditions:

(a) Seasonal Restrictions:
1. (1) In any area in which there is a closed ice fishing season, a shack or temporary structure must be removed by ice out or within 3 days after the season closes, whichever comes first.
2. (2) In any area where there is no official close of the ice fishing season, a shack or temporary structure must be removed by ice out or March 31, whichever comes first.
