Law360, New York (March 31, 2017, 3:40 PM EDT) -- On March 28, 2017, President Donald Trump issued his long-awaited executive order, "Promoting Energy Independence and Economic Growth," outlining his plan to reconsider and withdraw actions taken by former President Barack Obama to address global climate change. The EO takes aim at a series of key programs and policies, including the Clean Power Plan, oil and gas methane regulations, the coal leasing moratorium, the social cost of carbon metric, the National Environmental Policy Act greenhouse gas guidance, and the president's Climate Action Plan. Significantly, the EO also requires agencies to identify other actions "related to or arising from" the Climate Action Plan for reconsideration.

But the EO is not limited to climate-related initiatives. Rather, it calls for a potentially sweeping reexamination and rebalancing of U.S. policy regarding energy and the environment. As described in more detail below, the EO sets into motion a new Office of Management and Budget review process affecting all federal agencies whose actions "potentially burden" the development or use of domestic energy resources – particularly oil, natural gas, coal and nuclear power – regardless of whether the actions relate to climate change. The review process culminates in a 180-day deadline for agencies to identify additional regulations and policies for reconsideration or rescission.

This article provides an overview of the key elements of the EO and examines its implications for the future. Although the EO provides an important articulation of the administration's priorities related to energy, environment, economic growth and climate-related policies, it raises as many questions as it answers, creating both challenges and opportunities for the regulated community. For some sectors, the EO will present an opening for clients to address legacy policies to achieve regulatory objectives that may not have been possible previously. It will be imperative for interested parties across the spectrum to monitor developments closely, assess impacts for ongoing and future operations, and evaluate possible opportunities to participate in the administrative and legal processes as they unfold.

New Domestic Energy Policy Review Process

Section 1 of the EO articulates national policy objectives relating to the promotion of domestic energy resources, economic growth and job creation. With respect to the environment, the EO recognizes that federal agencies must "promote clean air and clean water for the American people," where "permitted by law" (sec. 1(d)), but it makes clear that agencies must at the same time avoid regulatory burdens that "unnecessarily" encumber domestic energy production or job creation. It directs agencies to ensure that "environmental regulations comply with the law, are of greater benefit than cost, ... achieve environmental improvements for the American people, and are developed through transparent processes that employ the best available peer-reviewed science and economics" (sec. 1(e)).

Section 2 of the EO then orders a sweeping policy review of all agency actions (defined broadly to include regulations, orders, guidance documents and policies) that "potentially burden" the safe, efficient development of domestic energy resources (sec. 2(a)). "Burden" is defined to mean "unnecessarily obstruct, delay, curtail or otherwise impose significant costs on the siting, permitting, production, utilization, transmission or delivery of energy resources" (sec. 2(b)).

The EO sets in motion a series of processes with deadlines: 45 days for agencies to submit a plan to the OMB; 120 days to submit a draft final report with recommendations; and 180 days for the plans to be finalized (unless extended by the OMB). At the end of the review process, which will be coordinated by the OMB, the EO directs agencies, as soon as practicable, in accordance with specific recommendations in their final reports, to "suspend, revise or rescind, or publish for notice and comment proposed rules suspending, revising or rescinding" the actions they identified (sec. 2(g)).

In the near term, agencies will likely be working rapidly to interpret the EO and figure out how it affects their various programs and policies. Clients with particular interests in the continuation, modification or reversal of any specific programs or policies that could fall within the scope of the new domestic energy policy review will need to keep careful track of this decision-making process and seek opportunities to provide input.

Reconsideration of the CPP (EO Section 4)

Not surprisingly, a central focus of the EO is the Clean Power Plan. The CPP, finalized in August 2015, established national standards limiting carbon emissions from existing coal and natural gas-fired power plants under Section 111(d) of the Clean Air Act.1 Hailed by some as a necessary step in combating climate change, critics of the CPP argued (among other things) that it would force states to reconfigure their electricity-generating portfolios, resulting in the further retirement of coal-fired power plants in favor of natural gas and renewable sources, and cause higher electricity prices.

The U.S. Supreme Court stayed implementation of the CPP in February 2016 pending completion of legal challenges brought by industry groups and more than 25 states. The D.C. Circuit, sitting en banc, heard argument on the CPP's validity in September 2016. The D.C. Circuit has yet to issue a decision.

EO's Directives:

  • Orders the U.S. Environmental Protection Agency to review the CPP rule for consistency with the EO's policy statements (sec. 1) and, if appropriate, and as soon as practicable, "publish for notice and comment proposed rules suspending, revising or rescinding" the rule (sec. 4 and 4(b)(i)). The EO also applies to any rules or guidance issued pursuant to the CPP (sec. 4), including the proposed federal plan and model trading rules (sec. 4(b)(iii)),2 as well as the legal memorandum that the EPA published in conjunction with the CPP (sec. 4(c)).3
  • Orders the EPA to take the same steps with respect to the section 111(b) new source performance standards (NSPS) for new, modified and reconstructed power plants (sec. 4(b)(ii)).4
  • Authorizes the U.S. attorney general to provide notice of the EO to the D.C. Circuit and request that the court stay or otherwise delay litigation in any cases challenging the above rules, or seek other appropriate relief, pending the completion of the administrative process (sec. 4(d)).

Questions and Implications:

  • The EO requires the EPA to review the CPP, but provides no guidance as to which specific legal or factual issues the EPA should re-examine. Nor does it provide specifics on process or timing. This leaves the EPA with a wide array of options with different policy ramifications and degrees of litigation risk.
      • On one end of the spectrum, the EPA could conceivably revisit positions on issues that would undermine the CPP's legal foundation. For example, the EPA could conceivably adopt the position (advanced by CPP opponents in the D.C. Circuit) that it is statutorily barred from issuing Section 111(d) standards for greenhouse gas emissions from power plants because it is already regulating those sources for emissions of hazardous pollutants under Section 112. Such a move would, if sustained through inevitable litigation, preclude any further development of standards for greenhouse gases from existing power plants under Section 111(d). (Note: This would be the result so long as the EPA continues to defend, and is successful in defending, the Section 112 mercury and air toxics rule5 for power plants, which is also currently under review in the D.C. Circuit. That rule is also possibly subject to review under the EO as potentially burdening the use of domestically produced energy resources.)
      • On the other hand, the EPA could decide to leave intact its legal authority to issue the section 111(d) standards, but refashion those standards in ways that might reduce their stringency or enforceability. For example, for coal-fired plants, the EPA could focus exclusively on heat rate efficiency measures achievable within the "fence line" of the facilities (i.e., what is referred to as "Building Block 1"); and the EPA could defer action on – or reconsider on legal grounds – other elements of the CPP that require generation-shifting to natural gas ("Building Block 2") or zero-emitting sources such as wind and solar ("Building Block 3"). The EPA could also seek to reduce stringency by reconsidering any number of record issues, such as those relating to costs and grid reliability. Among the many possibilities, the EPA could also attempt to reinterpret the respective responsibilities of the EPA and the states under Section 111(d), giving more say to the states on what the standards should be and leaving the EPA with a more limited role.
      • It is also possible that the EPA will do none of the above. There are a number of approaches it could take that would allow it to defer these questions, for now. For example, the promulgation of an NSPS for new power plants under Section 111(b) is a prerequisite for a Section 111(d) rulemaking for existing sources. Because the EO directs the EPA to reconsider the Section 111(b) NSPS rule, the agency could conceivably decide to initiate the administrative process for that predicate rule first, which could consume a significant amount of time, before deciding what to do about 111(d).
      • In short, the EO does not specify whether the EPA should pursue a strategy of "repeal and replace," or simply "repeal," of the CPP. Nor does it provide guidance on what any "replacement" would look like. The possibilities are numerous and the stakes are high. Businesses in all relevant sectors will want to monitor the process closely as it unfolds, and look for opportunities to have their voices heard.
  • Hours after Trump signed the EO, the U.S. Department of Justice filed a motion asking the D.C. Circuit to hold the case in abeyance. The EPA also signed a Federal Register notice announcing its review of the CPP and providing advanced notice of forthcoming rulemaking proceedings. We note that courts are usually amenable to requests for abeyances where there is a significant change in circumstances, such as a presidential transition. Nonetheless, we can expect to see proponents of the CPP resist putting the litigation on hold and argue that the court should render its decision.
  • The practical effect of withdrawing the CPP is unclear, to the extent energy prices render investments in new coal-fired power plants impractical and lead utilities to continue to build new capacity using natural gas, wind and solar, depending on the relative economics of these sources at the time. The price of natural gas is difficult to predict, while the capital cost of wind and solar is dropping, and methods to resolve the intermittency of wind and solar are improving. Furthermore, companies may be hesitant to rely on the current administration's position favorable to coal-fired power in making long-term investments that will depend on conditions beyond the term of this administration. In the shorter term, the reversal of the CPP may mean that coal will be dispatched more than it would be otherwise over the next few years. It may also prolong the life of some older coal plants and delay inside-the-fence line efficiency improvements in those plants that will stay in operation. Beyond that, the impact on capital planning may be limited. We will continue to analyze the practical impacts for the energy industry in the coming weeks and months.

Other Elements of the EO

The EO also addresses several other key policy and regulatory initiatives in the energy and environment sector.

Lifting of Moratorium on Coal Leasing (EO Section 6)

The EO immediately rescinds a moratorium on new leases for coal mining from approximately 570 million acres of federal lands, which the U.S. Department of the Interior's Bureau of Land Management issued in January 2016.6 The suspension of new leasing was intended to last for a minimum of three years. The DOI explained the temporary halt as a central component of a plan to broadly re-examine the nation's decades-old coal leasing program, which has not been extensively reviewed since the 1980s, and which the agency believed merited review in light of changing economic, public health and environmental considerations.

The EO instructs the secretary of the Interior to "take all steps necessary and appropriate to amend or withdraw" the programmatic review, leaving open the possibility that the review will be amended rather than terminated (sec. 6).

Questions and Implications:

  • While lifting the moratorium will immediately reopen the 570 million acres where the federal government owns the coal mineral estate, many U.S. coal companies may not be looking to secure new reserves in the near term given the sector's recent downturn. Decreased demand spurred by competition from natural gas and renewables, and by the decline in coal exports, has decreased production in many of the federally owned reserves.

Review of Federal Regulations on Energy Development (EO Section 7)

The EO also instructs the EPA and DOI to "review" several Obama-era regulations and guidance related to oil and gas development, and "if appropriate ... suspend, revise or rescind the guidance, or publish for notice and comment proposed rules suspending, revising or rescinding those rules" (sec. 7(a), (b)). As noted above in reference to the CPP, the effects of these mandated reviews have yet to be seen – the measures could be rescinded, modified or (less likely) kept intact. Each review will generate questions about the process required for reevaluation: When will the reviews begin? What will the agencies prioritize? How will the agencies draft new rules to withstand legal challenge?

The EO also authorizes the attorney general, in his discretion, to "request that [a] court stay [] litigation or otherwise delay further litigation" over any of the subject rules (sec 7(c)).

Some of the key rules targeted for review are as follows.7

BLM Methane Regulations (EO Sec. 7(b)(iv))

The EO instructs the DOI to review the BLM's methane and waste prevention rule, which was finalized in November 20168. The rule, which is designed to reduce emissions of methane (a greenhouse gas), prohibits the venting of natural gas from oil wells (with limited exceptions), requires companies to update their equipment and processes to limit natural gas flaring, and requires operators to submit a plan outlining how they plan to capture escaping gas before drilling a development oil well. The rule was challenged in court almost immediately after finalization.9

The U.S. House of Representatives voted in February 2017 to approve a Congressional Review Act resolution against the rule, which is pending in the Senate.10 Whether Congress takes any further action in light of the EO remains to be seen.

EPA Methane Regulations (EO Sec. 7(a))

The EO also directs the EPA to review its methane rules for new oil and gas infrastructure that were finalized in May 2016 – the EPA's first-ever methane standards for new, modified and reconstructed sources.11 These rules were aimed at reducing methane emissions from new and modified sources by 40 to 45 percent (from 2012 levels) by 2025, and also set standards for volatile organic compounds and other air pollutants.

The EPA took initial steps to write similar regulations for existing sources by sending an information request to industry groups last year. However, on March 3, 2017, EPA Administrator Scott Pruitt withdrew the information request.

BLM Hydraulic Fracturing Regulations (EO Sec. 7(b)(i))

The EO also directs the DOI to review a 2015 BLM rule regarding hydraulic fracturing on federal and tribal lands.12 The rule imposes stringent well casing and wastewater storage requirements and requires drillers to publicly disclose chemicals used in hydraulic fracturing within 30 days of completing operations. It also mandates stricter storage protocols for recovered wastewater and requires drillers to submit detailed information on the geology, depth and locations of existing wells for the purpose of lowering the risk of cross-contamination from chemicals.

Earlier this month, the government sought a temporary abeyance from the Tenth Circuit in a legal challenge to the rule, explaining that it does not align with the current administration's policies. The court canceled the oral arguments scheduled for earlier this week.

Withdrawal of the Social Cost of Carbon Metric (EO Section 5)

The EO withdraws a budgeting metric used by the Obama administration to assign a dollar amount to the economic impact of carbon dioxide pollution. This monetary value, also known as the "social cost of carbon," represents an estimate recommended by an interagency working group convened by the Council of Economic Advisers and the Office of Management and Budget of the long-term benefit to society of reducing emissions of carbon dioxide and other greenhouse gases on a carbon equivalent basis.13 The EPA has previously stated the social cost of carbon values (in 2007 dollars per metric ton CO2) as $36 for 2015 and $42 for 2020.14

The social cost of carbon estimate was one component of the Obama administration's economic justification for regulations both aimed directly at reducing greenhouse gases (for example, greenhouse gas standards for cars and trucks), and those aimed at other pollutants with a collateral benefit of reducing greenhouse gases (for example, regulation of hazardous air pollutants from power plants that would encourage retirement of such plants in favor of other types of electricity generation). The basic rationale is that measures to reduce greenhouse gases costing industry less than the EPA's determination of the social cost of $36 per ton of carbon equivalent are worthwhile because they result in a net benefit to society by avoiding greater economic costs associated with the contribution of those greenhouse gases to climate change.15

The EO requires from this point forward that agencies, "when monetizing the value of changes in greenhouse gas emissions resulting from regulations," and conducting a regulatory cost-benefit analysis, adhere to the guidance in OMB Circular A-4 (EO sec. 5(c)).

Questions and Implications:

  • The practice of estimating the economic costs and benefits of most government regulations has been in place for decades, and the EO recognizes that agencies will continue to conduct such analyses, including "monetizing the value of changes in greenhouse gas emissions resulting from regulations" (EO sec. 5(c)).16
  • However, eliminating the social cost of carbon metric could provide an economic justification for proposing less stringent regulations. In particular, the EO's direction for agencies to adhere to OMB Circular A-4 may result in a greater discount rate for future harms and/or an exclusive focus on harms incurred within the United States.

Revocation of Climate-Related Policies (EO Section 3)

The EO revokes several nonbinding executive policies and reports from the previous administration, including several presidential memoranda and initiatives related to climate change – for example, preparing for impacts of climate change and addressing climate change threats in the national security context (EO sec. 3(a),(b)). The two most important affected policies are the White House Council on Environmental Quality's greenhouse gas guidance and Obama's overarching Climate Action Plan.

Council on Environmental Quality Greenhouse Gas NEPA Guidance

The EO rescinds the Obama-era guidance for federal agencies on how to consider greenhouse gas emissions and the effects of climate change as part of the environmental reviews required by NEPA (EO sec. 3(c)). The CEQ finalized that guidance in August 2016 after a multiyear interagency process.17 Under NEPA, federal agencies are required to consider and disclose the potential effects of their proposed actions and decisions on the environment. The CEQ guidance provided methods for agencies to use in describing and quantifying greenhouse gas emissions or projected climate change impacts resulting from proposed federal actions, and provided that agencies should use quantitative rather than qualitative methods to assess greenhouse gas emissions where feasible.

Questions and Implications:

  • While the policy directives of rescinding the CEQ guidance signal the White House's interest in reducing the role climate change plays in analysis of federal agency actions, the legal implications of such action are less certain. CEQ guidance documents, though "persuasive authority offering interpretive guidance regarding the meaning of NEPA and the implementing regulations," are not treated with the same judicial deference afforded to administrative rules that are the product of notice and comment rulemaking.18

President's Climate Action Plan

The EO rescinds the 2013 Climate Action Plan (EO sec. 3(b)), which articulated the Obama administration's commitment to reducing the nation's greenhouse gas emissions and becoming a global leader in climate change initiatives.19 The Climate Action Plan encompassed a number of efforts to improve energy efficiency standards, encourage investment in renewable energy, update the electricity grid, develop infrastructure and policies to address on-the-ground climate change impacts, and enhance collaboration between states, industry and other sectors in setting emissions standards.

Critically, the EO requires that "the heads of all agencies shall identify existing agency actions related to or arising from" the Climate Action Plan and related policy documents (EO sec. 3(d)) and requires each agency to "suspend, revise or rescind, or publish for notice and comment proposed rules suspending, revising or rescinding any such actions," as "appropriate and consistent" with the policies set forth in Section 1 of the EO. This mandate could potentially be interpreted as a sweeping requirement that could require extensive reconsideration of major actions taken in relation to the Climate Action Plan and other executive initiatives, and will depend on interpretation of what is "appropriate and consistent" with the EO's policies.

What the EO Does Not Address

EPA's Legal Obligation to Regulate Greenhouse Gases Under the CAA

The EO's provisions are also notable for what they don't do. Critically, the EO does not direct the EPA to withdraw or reconsider its 2009 "endangerment finding"20 under Section 202(a) of the CAA that greenhouse gas emissions endanger the public health and welfare (a necessary predicate for regulating greenhouse gases as a pollutant under the CAA). The EO also does not seek to revisit or question the fundamental holding of Massachusetts v. Environmental Protection Agency "[b]ecause greenhouse gases fit well within the [CAA]'s capacious definition of "air pollutant," ... the EPA has the statutory authority to regulate the emission of such gases from new motor vehicles."21 The decision not to require the EPA to re-open the endangerment finding is highly significant because to do so would have: (a) required the EPA to revisit the scientific underpinnings of its previous finding; and (b) called into question the basic authority of the EPA to issue regulations of greenhouse gas emissions under the CAA. We note, however, that it is conceivable that the EPA could identify the endangerment finding as within the scope of Section 2 of the EO (requiring review of existing actions that potentially burden the development of domestic energy resources).

2015 Paris Agreement

The EO is also silent with respect to the international climate change agreement brokered in Paris at the December 2015 United Nations Climate Change Conference, which went into effect in November 2016. The Paris agreement aims to limit global warming well below 2 degrees Celsius and as close to 1.5 degrees Celsius as possible, and sets nonbinding carbon emission reduction goals and related financing strategies. Under the Paris agreement, the U.S. pledged to reduce greenhouse gas pollution by 26 to 28 percent by 2025 (from 2005 levels). The reconsideration process triggered by the EO will likely place the achievement of that pledge further out of reach.

The White House stated in a background briefing on March 27, 2017, that the administration is still discussing whether the U.S. will withdraw from the Paris agreement.


The EO, sweeping in scope, raises as many questions as it answers, but presents both challenges and opportunities for clients. It is not the end point, but rather a step in a potentially lengthy series of legal and administrative processes. We will continue to monitor the political and regulatory landscape closely to identify opportunities for clients and stakeholders to help shape the administration’s regulatory agenda as it unfolds.
