Subject: Badlands National Park Proposed Air Tour Management Plan and Environmental Assessment
Dear Superintendent Veach:
I am writing on behalf of over 2,400 members of the Coalition to Protect America’s National Parks (Coalition), all of whom have worked or volunteered for the National Park Service (NPS) and who collectively represent more than 45,000 years of national park management experience. The Coalition studies, educates, speaks, and acts for the preservation of America’s National Park System. Among our members are former NPS directors, regional directors, superintendents, resource specialists, rangers, maintenance and administrative staff, and a full array of other former employees, volunteers, and supporters.
We offer the following comments for your consideration regarding the proposed Air Tour Management Plan (ATMP) and Environmental Assessment (EA) for Badlands National Park (BADL or Park), as described at:
- First, we commend the agencies for preparing a proper environmental assessment (EA) for the proposed ATMP that considers a range of alternatives and evaluates the potential impacts of those alternatives –When considering a proposed agency action, such as a new ATMP, NPS must comply with the National Environmental Policy Act (NEPA) and related guidance, including the Council on Environmental Quality (CEQ) NEPA implementing regulations (40 CFR Parts 1500-1508) and with the agency’s own NEPA guidance found in the NPS NEPA Handbook 2015. We have been deeply concerned that NPS has failed to comply with basic NEPA guidance by issuing numerous previous “proposed ATMPs” for other parks without considering a reasonable range of alternatives and without preparing any sort of NEPA analysis for public review. We applaud you and the planning team for following the appropriate NEPA process requirements that the BADL proposal deserves.
- Compliance with the NPS Organic Act (54 USC §100101) is integral to compliance with the National Parks Air Tour Management Act (49 USC §40128), yet the EA barely mentions the Organic Act or its relevance – Section 802 (Findings) of the National Parks Air Tour Management Act (NPATMA) states, in part: “Congress finds that—
(1) the Federal Aviation Administration has sole authority to control airspace over the United States;
(2) the Federal Aviation Administration has the authority to preserve, protect, and enhance the environment by minimizing, mitigating, or preventing the adverse effects of aircraft overflights on public and tribal lands;
(3) the National Park Service has the responsibility of conserving the scenery and natural and historic objects and wildlife in national parks and of providing for the enjoyment of the national parks in ways that leave the national parks unimpaired for future generations” (Emphasis added)
The NPS “responsibility for conserving” park resources and values mentioned in subsection # 3 of the NPATMA above derives directly from the NPS Organic Act of 1916 and is often referred to as the NPS “conservation mandate.” As described in NPS Management Policies 2006, Section 1.4.1: “The most important statutory directive for the National Park Service is provided by interrelated provisions of the NPS Organic Act of 1916 and the NPS General Authorities Act of 1970, including amendments to the latter law enacted in 1978.” As further stated in Management Policies Section 1.4.3:
The fundamental purpose of the national park system, established by the Organic Act and reaffirmed by the General Authorities Act, as amended, begins with a mandate to conserve park resources and values. This mandate is independent of the separate prohibition on impairment and applies all the time with respect to all park resources and values, even when there is no risk that any park resources or values may be impaired… Congress, recognizing that the enjoyment by future generations of the national parks can be ensured only if the superb quality of park resources and values is left unimpaired, has provided that when there is a conflict between conserving resources and values and providing for enjoyment of them, conservation is to be predominant. This is how courts have consistently interpreted the Organic Act. (Emphasis added)
In addition, the Badlands National Park enabling legislation provides that “[t]he administration, protection, and promotion of said Badlands National Park shall be exercised under the direction of the Secretary of the Interior by the National Park Service, subject to the provisions of the Act of August 25, 1916” (which is the NPS Organic Act). See 16 USC §441c. In other words, the Park is to be managed in accordance with the NPS conservation mandate and “when there is a conflict between conserving resources and values and providing for enjoyment of them, conservation is to be predominant.”
Given that both the proposed ATMP and the EA are or should be focused on evaluating potential impacts of commercial air tours on the park’s natural and cultural resources, visitor experiences, and tribal lands within and adjacent to the park, we would expect the NPS conservation mandate to serve as a key basis for evaluating those impacts. However, we are quite concerned that the EA barely mentions the Organic Act (e.g., it is mentioned once at EA p. 87). In our view, the NPS conservation mandate is so important to the management of air tours in national parks that Congress embedded a key portion of the Organic Act in Section 802(3) of the NPATMA. To address this concern, we recommend that a section summarizing applicable laws relevant to the proposed action, including the NPS Organic Act and the BADL enabling legislation be added to Chapter 1 or as an appendix.
- The EA appropriately considers the 2017 Foundation Document for Badlands National Park, which provides important context for the planning process regarding the park’s significance and fundamental resources that could be adversely affected by commercial air tours –Relevant sections of the Foundation Document include the following:
(p. 5) Park Significance: “The park contains spectacular scenery, predominantly highly eroded landforms that comprise a concentrated collection of rutted ravines, serrated towers, pinnacles, and precipitous gulches… The park protects places of spiritual and historical significance to the Lakota people… The North Unit preserves 64,250 acre of designated wilderness… The park provides unparalleled opportunities to observe … native animals in their natural habitat.”x
(pp. 6-7) Fundamental Resources and Values: “Fundamental resources and values help focus planning and management efforts on what is truly significant about the park. One of the most important responsibilities of NPS managers is to ensure the conservation and public enjoyment of those qualities that are essential (fundamental) to achieving the purpose of the park and maintaining its significance. (Emphasis added) If fundamental resources and values are allowed to deteriorate, the park purpose and/or significance could be jeopardized. The following resources and values have been identified as “fundamental” for Badlands National Park:
Archeological and Ethnographic Resources – The White River Badlands are a place of spiritual and historical significance for many Native American groups, especially for the Lakota people.
Scenic Views – The erosion of sediments provides an array of dramatically changing vistas. The spectacular shapes and colors of the landscape range from the low rolling hills to tall walls and spires.
Native Wildlife – Badlands National Park supports range for wildlife native to the mixed-grass prairie of the northern Great Plains. Visitors can encounter bison, bighorn sheep, and pronghorn.
Wilderness Experience/Values – The expanse of the remote and wild landscape within the Sage Creek Wilderness area provides the opportunity for exploration and solitude. The lack of urban noise pollution allows visitors to experience the natural soundscape of the prairie.
While the Foundation Document does not say so specifically, the spiritual / sacred importance of the Badlands to the Lakota people cannot be overstated. Chief Spotted Elk (Big Foot) and his band of Lakota came through what is now Badlands NP in December 1890 on their way to their rendezvous with fate at Wounded Knee on December 29, 1890. According to oral history, the last Ghost Dances took place in what is now the South Unit of Badlands NP. As a result, the sacred nature of the Badlands landscape to the Lakota people provides one of the, if not the most, compelling reasons to eliminate air tours at BADL.
In brief, protecting Places of Spiritual Significance for Native American Groups, Scenic Values, Native Wildlife, and Wilderness Experience/Values are all closely related to and dependent upon preserving the “natural setting” of the Park. Protecting the “natural setting” from visual and noise intrusions of low-flying air tours, especially the many helicopter tours proposed at BADL, is fundamental to conserving the resources and values described above.
- Consistent with NPS Management Policies Section 1.5, the EA should include an “appropriate use analysis” for the proposed action – Management Policies Section 1.5 states, in part: “An ‘appropriate use’ is a use that is suitable, proper, or fitting for a particular park, or to a particular location within a park. Not all uses are appropriate or allowable in units of the national park system, and what is appropriate may vary from one park to another and from one location to another within a park…When proposed park uses and the protection of park resources and values come into conflict, the protection of resources and values must be predominant. A new form of park use may be allowed within a park only after a determination has been made in the professional judgment of the superintendent that it will not result in unacceptable impacts.” (Emphasis added)
The NPATMA established procedural requirements for allowing air tours over parks; however, the Act does NOT mandate that commercial air tours are appropriate and must be allowed. In fact, section (b)(3)(A) of the Act provides that the agencies “may prohibit commercial air tour operations over a national park in whole or in part.” Under the Act, air tours are essentially a discretionary activity subject to agency approval. To our knowledge, NPS has never formally considered or determined whether commercial air tours are an appropriate use of (or over) BADL. As a result, we strongly recommend that the EA be amended (e.g., through errata or as an appendix) to include an appropriate use analysis as described in Management Policies Section 1.5. Given the many adverse impacts of air tours that are described in the EA, we would expect that such an analysis would find that commercial air tours are NOT an appropriate use of (or over) BADL.
- The eventual decision document for the ATMP should include an “impairment determination” for the proposed action – NPS Management Policies Section 1.4.7, states, in part: “Before approving a proposed action that could lead to an impairment of park resources and values, an NPS decision-maker must consider the impacts of the proposed action and determine, in writing, that the activity will not lead to an impairment of park resources and values. If there would be an impairment, the action must not be approved.” (Emphasis added) Furthermore, “[t]he impact threshold at which impairment occurs is not always readily apparent. Therefore, the Service will apply a standard that offers greater assurance that impairment will not occur. The Service will do this by avoiding impacts that it determines to be unacceptable. These are impacts that fall short of impairment, but are still not acceptable within a particular park’s environment.” (Emphasis added) As a result, we strongly recommend that the eventual decision document, presumably a Finding of No Significant Impact (FONSI), includes an impairment determination as described in Management Policies Section 1.4.7.
- Section 8.0 (“Amendment”) of the ATMP itself should be revised – We have a significant concern about Section 8.0 in the proposed ATMP. This section of the ATMP is not described in the EA. The boilerplate language used in Section 8 (ATMP p. 6) states that “the ATMP may be amended at any time” (emphasis added) if either NPS or the FAA notifies the other agency. We imagine that the Amendment clause is intended to convey the concept that the ATMP could be updated and revised if/when the agencies determine it is needed and appropriate; and we fully understand that all management plans are subject to future change.
However, the use of the words “at any time” creates the distinct impression that reversal of the final ATMP decision and/or resumption of air tours at BADL could happen on relatively short-notice (i.e., “at any time”). Such wording suggests there is little certainty that elimination of air tours at BADL would be a durable decision (since it could be changed “at any time”). In our view, creating such uncertainty in the ATMP unnecessarily invites industry appeals and/or political intervention on behalf of air tour operators. Our observation has been that many NPS management decisions that curtail or eliminate controversial recreational and commercial activities in parks, such as off-road vehicle (ORV) use, hunting, and in this case commercial air tours, are often subject to industry lobbying and/or political reversal, especially if/when there is a change in administration.
Over 20 years after the passage of the NPATMA, litigation was needed to force the agencies to finally prepare the required ATMPs. Moving forward, it is critical that the new ATMPs are widely viewed as providing for consistent long-term air tour management at the individual parks involved, rather than leave room for uncertainty. Toward that end, we recommend that the agencies revise the wording of Section 8.0 of the ATMP itself to state the following:
(add new first sentence) This ATMP will remain in effect until amended or terminated by mutual agreement of the agencies. This ATMP may be amended at any time (i.e., delete: “at any time”): if the NPS, by notification to the FAA and the operator(s), determines that the ATMP is not adequately protecting Park resources and/or visitor enjoyment; if the FAA, by notification to the NPS and the operator(s), determines that the ATMP is adversely affecting aviation safety and/or the national aviation system; or, if the agencies determine that appropriate changes to this ATMP are necessary to address new information or changed circumstances.
These minor revisions would affirm the intended stability and longevity of the ATMP; and refocus the Amendment provision on the limited circumstances that could justify reconsideration of the ATMP, rather than on the infinite possibility of amending the ATMP.
- Section 1.4 Purpose and Need – As explained in General Comment # 2 above, compliance with the NPS Organic Act (54 USC §100101) is integral component of the National Parks Air Tour Management Act (49 USC §40128), yet the EA barely mentions the Organic Act or its relevance. As stated in EA section 1.4, “The purpose of the ATMP is to comply with the Act and other applicable laws…” (Emphasis added) This would seem to be the perfect opportunity to identify the “other applicable” laws, such as the NPS Organic Act and the BADL enabling legislation, that the agencies may have considered during the development of the ATMP. This could be addressed by providing a brief summary of “other applicable laws” in Chapter 1 or as an appendix to the EA.
- Section 1.5 Environmental Impact Categories Not Analyzed in Detail – As described in this section, the agencies have appropriately identified a number of impact categories that were considered but not analyzed in detail. In our view, the dismissed categories are generally not relevant or significant to the analysis; and the impact categories that have been carried forward for detailed analysis in the EA include the most relevant or significant impact topics for the analysis that follows in Chapter 3 of the EA.
- Section 2.1 Alternatives Development – We appreciate the detailed description of how the ATMP preliminary alternatives were developed primarily by an NPS inter-disciplinary team and then reviewed by the FAA. We also appreciate the detailed references to the Park’s Foundation Document purposes and management objectives, which helped inform development of the alternatives. In general, we believe that the agencies have developed and considered an appropriate range of alternatives. It also is very appropriate that the alternative of “Air Tours Above Existing Levels or Air Tours at Existing Levels with Current Operating Parameters” was eliminated from further study for the reasons stated in Section 2.2.1.
- Section 2.4 Alternative 1 (No Action Alternative) – As described in this section, “[t]he No Action Alternative represents a continuation of what is currently flown under existing conditions…” We strongly agree with the statement that “[t]he No Action Alternative provides a basis for comparison but is not a selectable alternative because it does not meet the purpose and need for the ATMP (refer to Section 1.4, Purpose and Need).” (Emphasis added) It is evident from the impact analysis of the No Action Alternative in Chapter 3 that the existing air tour situation at BADL is causing unacceptable impacts to park resources and values that are supposed to be conserved unimpaired under the NPS Organic Act.
- Section 2.5 Alternative 2 (Preferred Alternative) – As described, Alternative 2 would prohibit commercial air tours within the ATMP planning area no later than 180 days after the ATMP is signed by all required signatories from both agencies. We strongly support the selection of Alternative 2 as the Preferred Alternative for the reasons described in the EA, which are: Alternative 2 provides the greatest level of protection for the purposes, resources, and values of the Park as well as Park management objectives; and is most responsive to tribal concerns.
Chapter 3 includes comparative analyses of the respective alternatives on various impact categories (i.e., resources or uses that would be affected by air tours) at BADL. Nearly every analysis indicates that Alternative 2, the elimination of air tours at BADL, would provide the greatest level of protection and/or restoration of resources at the Park. Our comments below are focused on the impact categories that we believe would receive the most significant benefits of implementing Alternative 2.
- Section 3.1 Noise and Noise-Compatible Land Use – This section includes appropriate references to relevant FAA and NPS policies. Specifically, FAA Order 1050.1F, paragraph 11-5.b(10) defines a noise sensitive area as “[a]n area where noise interferes with normal activities associated with its use. Normally, noise sensitive areas include residential, educational, health, religious structures and sites, parks, recreational areas, areas with Wilderness characteristics, wildlife refuges, and cultural and historical sites.” (Emphasis added) In other words, the entirety of BADL is considered a noise sensitive area under the FAA order and should be protected accordingly.
NPS Management Policies (2006) Section 4.9, Soundscape Management, directs the NPS to preserve soundscapes and the acoustic environment to the greatest extent possible and to restore these resources to their natural condition wherever they have become degraded by noise and unwanted sounds. In other words, NPS management polices direct NPS to restore the natural soundscape at BADL that has been adversely impacted by air tour noise.
Section 3.1’s comparative analysis of the noise levels likely to be caused by the respective alternatives strongly supports Alternative 2 (the NPS Preferred Alternative) as the alternative with the greatest likelihood of restoring the natural soundscape at BADL, consistent with FAA Order 1050.1F and NPS Management Polices Section 4.9. In contrast, other alternatives would perpetuate noticeable levels of air tour noise disturbance.
- Section 3.3 Biological Resources – This section includes analyses of the potential impacts of air tours biological resources, specifically Animalia, including multiple species that are federally listed as threatened or endangered. As described in the analysis, multiple protected bird, mammal, and insect species are adversely impacted by aircraft noise. We are particularly concerned about the impacts of helicopter noise disturbance on Bighorn Sheep lambs during the spring, as the Bighorn Sheep herd at Badlands NP is currently under extreme stress with the effects of a lung infection epidemic that has had a high mortality rate.
In essence, Alternative 2 (elimination of air tours) would provide the greatest level of protection to the Park’s biological resources and would likely “have no effect on federally listed threatened or endangered species.” See EA Appendix H. For these reasons, we fully support selection and implementation of Alternative 2.
- Section 3.4 3.4 Cultural Resources – The National Historic Preservation ACT (NHPA), 54 U.S.C. §§ 300101 et seq., is comprehensive federal preservation legislation intended to protect cultural resources. Section 106 of the NHPA (54 U.S.C. § 306108), as implemented in 36 CFR Part 800, requires federal agencies to consider the effects of undertakings on historic properties, should any such properties exist. In addition to Section 106 of the NHPA, the NPS’s Organic Act* and Section 110 of the NHPA apply to and provide for the preservation of historic, ethnographic and cultural resources on parkland. (*This is a rare instance in which the EA actually mentions the NPS Organic Act.)
Table 15 in the EA identifies 21 cultural resources within the Area of Potential Effect (APE), inclusive of ethnographic resources, traditional cultural properties (TCPs), sacred sites, cultural landscapes, historic districts, and prehistoric and historic buildings and structures that have been previously documented in the APE or identified through consultation. Cultural resources of importance to Native American tribes are particularly noteworthy. The Lakota and many other tribes consider the continuous landscape extending from the Black Hills to the Park sacred, and Bear Butte at the northeast edge of the Black Hills is a popular worship site. The region was used by numerous Native American tribes for resource gathering, especially for timber, and for religious purposes. For the purposes of this draft EA, the agencies assume that all lands within the Park have spiritual and sacred qualities and consider the entire Park a TCP.
As described in the EA, the elimination of commercial air tours from the ATMP planning area would reduce the direct noise and visual intrusions from impacting the feeling and setting of cultural resources within the APE and result in beneficial impacts to ethnographic resources and sacred sites, TCPs, archeological resources, cultural landscapes, historic districts, and prehistoric and historic buildings and structures compared to the No Action Alternative. In other words, Alternative 2 would provide the greatest level of protection for the diverse cultural resources within the APE. For this reason, we fully support selection and implementation of Alternative 2 as it would be the most appropriate alternative to implement under applicable NHPA, FAA, and NPS cultural resource guidelines and policies.
- Section 3.5 Wilderness – The Wilderness Act of 1964 is the primary federal legislation regulating the management of designated Wilderness areas. In 1976, Congress designated 64,250 acres of the North Unit of the Park as the Badlands Wilderness. The Badlands Wilderness is divided into two geographically separate units, referred to by the NPS as the Sage Creek Unit and Conata Basin Unit. While Wilderness is not an impact category FAA traditionally examines, as a land management agency, the NPS is required to preserve Wilderness character.
NPS Management Policies (2006), § 6.1. states: “The purpose of Wilderness in the national parks includes the preservation of Wilderness character and Wilderness resources in an unimpaired condition.” As described in NPS Director’s Order # 41, Section 6.2, Wilderness character is the combination of biophysical, experiential, and symbolic ideals that distinguishes wilderness from other lands. The five qualities of wilderness character are (1) untrammeled, (2) undeveloped, (3) natural, (4) offers outstanding opportunities for solitude or primitive and unconfined recreation, and (5) other features of scientific, educational, scenic, or historical value.
Air tours would have no direct effect on the “untrammeled” and undeveloped” qualities of the Badland Wilderness; while potential impacts to “other features” (e.g., cultural resources) are evaluated elsewhere in the EA. As a result, the EA analysis focuses on potential impacts to the “natural” and “solitude” qualities of Wilderness character. As described in this section of the EA, commercial air tours primarily impact the “natural” and “solitude” qualities of Wilderness character at BADL, while impacts to “other features” (e.g., cultural resources) are evaluated elsewhere in the EA. The analysis indicates that Alternative 2 (elimination of air tours) would provide the lowest level of air tour noise intrusion into Wilderness areas of the park and therefore would provide the greatest level of protection to Wilderness character. As a result, we fully support Alternative 2 as the most appropriate alternative to implement under applicable NPS wilderness stewardship policies.
- Section 3.6 Visitor Use and Experience and Other Recreational Opportunities – While visitor experience is not an impact category the FAA traditionally examines, the NPS has agency wide guidelines (e.g., NPS Management Policies § 8.2, 2006) for managing visitors within the National Park System. This section also examines impacts to air tour customers.
Existing air tours at BADL are concentrated over the northeast corner of the Park and directly impact visitor experience in the area of the Park with the highest visitation, including the Cedar Pass Area.
Between 2017 and 2019, the Park averaged 1.01 million recreational visitors annually, with the peak times being June to September which accounts for more than 75% of visitors each year (NPS, 2018b). During that same period, an average of 1,425 air tour flights occurred annually over the Park. Reporting data from 2017-2019 indicates that on a peak month average day, air tours fly over the ATMP planning area approximately 17 times per day. (EA p. 122).
The visual and noise intrusions of helicopter overflights inevitably have impacts, mostly negative, on the experience of many park visitors. As a result, every alternative that would allow continued helicopter tours at BADL at any level would adversely impact the experiences of a high number of park visitors on the ground, while providing an air tour experience to a comparatively limited number of air tour customers annually. How is it acceptable for the possibly positive experiences of several people on a helicopter tour to negatively impact dozens or hundreds of other park visitors on the ground? For these reasons, we fully support the “elimination of air tours” as the most appropriate alternative to implement at BADL.
- Section 3.8 Visual Effects – As described in this section, visual character refers to the overall visual makeup of the existing environment at Badlands National Park where the alternatives would be located. Visual resources are a key element within the Cedar Pass Developed Area landscape. Other opportunities within the Park for visitors to observe scenic viewsheds and wildlife include Loop Road, the primary road for sightseeing, where visitors can view the Badlands, its rock formations, and the prairie ecosystem.
Studies indicate that aircraft noise in national parks can impact human perceptions of aesthetic quality of viewsheds (Weinzimmer et al., 2014; Benfield et al., 2018). Under existing conditions, commercial air tours are flown near Park viewsheds along Loop Road and Sage Creek Rim Road. In general, commercial air tours detract from the visitor’s opportunity to observe these resources when commercial air tours are present (which occurs 17 times per day during a peak month average day).
The comparative analysis clearly indicates that Alternative 2 (elimination of air tours) would provide the greatest level of protection to the park’s visual resources; and therefore it is most appropriate for the agencies to select and implement Alternative 2.
- Section 3.10 Summary of Environmental Consequences – Table 18 provides a side-by-side comparison of the environmental consequences for each of the alternatives considered across each environmental impact category. This comparison provides overwhelming evidence that Alternative 2, elimination of air tours, would provide the greatest level of protection to or within the various impact categories analyzed in the EA. For these reasons, we strongly support selection and implementation of Alternative 2, which would eliminate air tours at BADL.
In closing, we greatly appreciate that the agencies have prepared a proper EA that evaluates the impacts of a range of air tour alternatives at Badlands National Park. The information and analysis provided in the EA provide overwhelming evidence that Alternative 2, elimination of air tours, is the most appropriate alternative to implement at the park. We appreciate the opportunity to comment on this important issue.
