In December 2016, the National Park Service implemented updated regulations for oil and gas drilling activities on park land. The new standards under Part 9, Subpart B (“Rule 9B”) address a number of long-neglected deficiencies which have persisted since the rule’s inception in 1979. Recent deregulatory moves by the Trump Administration, however, already threaten to repeal the rule. A March 28th executive order instructed agencies to “review” and “rescind” environmental regulations “that unduly burden the development of domestic energy resources.” Given the damage that unregulated drilling could do to the nation’s parklands, the administration should refrain from any weakening of the NPS’s new rule. If protections weaken, however, state governments should utilize their significant authority to enforce their own regulations to preserve federal parklands.
The Threat of Unregulated Drilling
Though the federal government owns the land that makes up the National Park System, private parties still own subsurface mineral rights in forty-two national parks, creating “split-estates.” Active drilling operations are present in twelve of these parks, totaling over five-hundred wells. If demand for drilling sites grows, thirty additional parks could be affected.
The NPS promulgated Rule 9B to minimize the harmful consequences of drilling operations by enforcing the use of safer methods and technologies. In December 2016, the NPS implemented a number of improvements to the rule. Among the most meaningful were a closing of the grandfather clause, which previously exempted more than half the drilling operations on NPS land, and the authorization to charge operators higher fees to enhance enforcement efforts and ensure proper cleanup of well sites. Recent actions by both the administration and Congress could threaten these changes and, as a result, the health of national parks.
Unregulated drilling operations pose a distinct threat to both the ecological sustainability of the parklands and the enjoyment of visitors. Among the harms documented by the NPS are degradation of the air, surface water, ground water, and soil; disruption of migratory routes and endangered habitats; disturbance of sensitive cultural sites; and noise pollution that can be heard from miles away. With expanded drilling operations, such harms could significantly degrade the value of national parks. That value, it must be noted, is immense. In addition to providing vital protections for some of the country’s most important biological hotspots, national parks are also instrumental to cultural conservation, enhance economic development, and advance critical research efforts including breakthroughs in climate science. Faced with possible non-enforcement or even withdrawal of federal protections, focus now shifts to available legal approaches.
The Role of State Regulation
The simplest solution would be for the administration to keep Rule 9B in place and provide sufficient funding for enforcement. Federal action could also come from Congress, which could authorize the purchase of private mineral rights underlying parklands. This approach would permanently resolve the issue of split-estates that gave rise to Rule 9B in the first place. Prospective solutions, however, should not, and do not, end at the federal level. State governments have the authority to impose their own environmental regulations in national parks.
Current jurisprudence outlines a bounded range of authority within which states can impose meaningful protections on federal lands, including national parks that lie within their territory. Several cases require mention. First, in Granite Rock the Supreme Court upheld the enforcement of a California state mining permitting program on federal lands. Unless federal law preempts states on the issue in question, states have the authority to promulgate “reasonable environmental regulations” and use the “full extent of their authority in enforcing [those regulations] on federal lands.” Federal preemption is established either where Congress evidences an intent to exclusively occupy a field or where state law conflicts with federal law by standing as an obstacle to the objectives of Congress. The Court determined that Congress did not intend to preempt California’s permitting requirement nor did California’s regulation conflict with federal law. Here, however, the court warns that a state rule which crosses the line between regulation of an activity and prohibition would likely conflict with federal regulations.
This limitation on state authority to prohibit was articulated in the 8th Circuit’s Lawrence County opinion which held that a county ordinance prohibiting new surface mining permits was preempted. The court determined that because surface mining was the only viable method in the area, the ordinance was a de facto ban on mining. A ban would, the opinion continues, run directly counter to relevant federal law which sought to encourage mining while merely regulating negative consequences. These two decisions, then, establish two extremes within which states can enforce regulations with California’s relatively unobtrusive permit on one end and Lawrence County’s functional ban on the other.
A string of recent cases has provided significant guidance on the admissibility of regulations that fall within this spectrum and establish an expansive basis for state action. Two opinions from the District of Oregon held that state regulations which effectively prohibited a common form of mining fell short of the standard in Lawrence County because other forms of mining were still permissible. A state regulation is not necessarily preempted by federal law even if it would render certain mining operations commercially impracticable. Additionally, the California Supreme Court upheld a moratorium on suction mining even though it was the only commercially viable method available. Importantly for state policymakers, the court noted that judges should be hesitant to strike down state regulations on federal lands because of an “overzealous” preemption doctrine. Instead, there should be a “strong presumption against preemption in areas where the state has a firmly established regulatory role.” The U.S. Supreme Court could clarify, or greatly disrupt, this issue if it chooses to hear the case.
To avoid preemption challenges, state regulations should fall short of outright bans on drilling in parklands, but this leaves significant authority to promulgate meaningful protections. States have authority to regulate drilling operations on parklands whether to prevent contamination of nearby ecosystems or to sanction and clean up infractions after they have occurred. Though states have historically fallen short of federal protection, they could choose to exceed federal regulations while resisting industry capture and adapting to local conditions and needs. Additionally, the Supreme Court’s test for federal preemption leaves the states with little to fear from preemption by Rule 9B itself given that its primary stated purpose is to “protect federally . . . owned lands [and] water” and the “uses or experiences” of NPS visitors. State regulation complements these goals rather than posing an obstacle to them.
NPS’s updated Rule 9B is an important step in mitigating the damage that drilling operations inflict on National Parks. The Trump Administration should not take any further steps that may endanger the Rule’s effectiveness. If, however, the federal government abdicates its role as protector of the nation’s environmental resources, states can and should step up by implementing necessary regulatory protections. State action on federal lands can be a small part of the broader push that scholar Heather Gerken terms “progressive federalism.” Federalism, Gerken argues, can be a powerful tool for achieving progressive political goals, particularly in the face of deregulation at the federal level. Given their importance, states should make the preservation of national parks one such progressive goal.
