In response to President Biden’s Executive Order entitled, “Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis,” the Environmental Protection Agency (EPA) recently issued a proposed rule taking aim at greenhouse gases (GHG) and volatile organic compounds (VOC) emissions from new and existing oil and natural gas production, processing, transmission, and storage facilities.  The proposal contains three basic components.  In a break with precedent, EPA did not provide proposed regulatory language.

First, the proposed rule would revise the new source performance standards (NSPS) for GHGs and VOCs for new, modified, and reconstructed sources, including the production, processing, transmission, and storage segments.  Specifically, EPA proposes to a new subpart OOOOb that would update and expand the current requirements under CAA Section 111(b) for methane and VOC emissions from sources constructed, modified, or reconstructed after November 15, 2021.  NSPS OOOOb would include standards for emission sources not regulated previously under the 2016 NSPS OOOOa.  Among other changes, EPA proposes to apply to VOC emissions thresholds to storage vessel tank batteries as opposed to individual storage tanks.  EPA has also suggested a change to the definition of legal and practical enforceability which could impact the utilization of state-level permitting previously used to reduce the potential to emit to below the 6 ton per year VOC-threshold.

Second, the proposed rule would create a new subpart OOOOc that would contain the first nationwide emissions guidelines (EG).  The EG would be a state model rule that states could use to develop, submit, and implement state plans that establish performance standards to limit GHGs from existing sources.…

As we reported, the California Legislature passed SB 1014 – the Clean Miles Standard and Incentive Program (the “Clean Miles Program”) – to reduce greenhouse gas emissions from “rideshare” vehicles. This led to the creation of the Clean Miles Standard regulation, which the California Air Resources Board (“CARB”) fully adopted in May 2021 after receiving stakeholder input. In sum, the Clean Miles Program directed CARB and the California Public Utilities Commission (“CPUC”) to develop and implement new requirements for transportation network companies (“TNCs”) like Uber and Lyft.  In this blog post, we discuss the goals and three core requirements of the Clean Miles Program, the new regulations CARB just adopted in furtherance of those core requirements, and other obligations that lie ahead for TNCs.

The Clean Miles Program sets more stringent emissions standards for TNCs over time and encourages TNC drivers to shift to electric vehicles.  The Clean Miles Program has three core requirements:

  • In 2020, CARB established a greenhouse gas (“GHG”) emissions baseline for vehicles used in TNCs on a per-passenger-mile basis using 2018 as the base year;
  • In 2021, CARB and CPUC adopted and implemented, respectively, targets and goals (beginning in 2023) for TNCs to reduce GHG emissions per passenger-mile driven; and
  • By January 1, 2022, and every two years thereafter, each TNC shall develop a GHG emissions reduction plan.

 CARB satisfied the first requirement and determined the baseline emission rate (301 grams of carbon dioxide (“CO2“) for each mile traveled.

In furtherance of the second and third requirements—CARB adopted (in May 2021) a “Clean Miles Standard” regulation that imposes new requirements that require TNCs to provide information including, but not limited to: (i) total miles that TNC drivers complete; (ii) share of miles completed by qualified “zero-emissions” (e.g., zero-emission vehicle); (iii) miles-weighted average of network-wide CO2 to produce an estimate of the GHG emissions; and (iv) total passenger-miles completed using an average passengers-per-trip estimate to account for trips where exact passenger headcount was not captured.  The new regulation also requires TNCs to submit annual reports and a compliance plan every two years starting in January 2022.…

On January 19, 2021, in a 2-1 decision, the D.C. Circuit Court vacated the Trump administration’s 2019 Affordable Clean Energy (ACE) Rule and remanded it to the U.S. Environmental Protection Agency (EPA). The decision offers a strong statement about EPA’s breadth of authority to regulate greenhouse gases (GHGs) under the Clean Air Act (CAA) and, if its position is upheld, clears the way for the Biden administration to regulate power plants.

The Affordable Clean Energy Rule

The EPA promulgated the ACE Rule in 2019 under the CAA, replacing the Obama administration’s 2015 Clean Power Plan (CPP). Both rules sought to reduce GHG emissions from the power sector; but where the CPP implemented broader industry-wide mechanisms, the ACE Rule limited reduction efforts to the actual source power plants.

The 2015 CPP offered “beyond the fenceline” tools for states to reduce emissions by replacing fossil fuels with renewable energy sources and participating in emissions credit-trading programs; however, in February 2016 the U.S. Supreme Court stayed the implementation of the CPP pending litigation in the D.C. Circuit. During the stay and subsequent freeze of litigation, the Trump administration rescinded the CPP and promulgated the ACE Rule.

In promulgating the ACE Rule, the Trump EPA took an alternative view of the CAA than the Obama EPA and reasoned that the CAA expressly limited the EPA’s power to only “at the source” emissions reduction options, such as heat rate improvement technologies. As a result, the Trump administration removed all of the CPP’s “beyond the fenceline” options and limited emissions restrictions to those applied directly to power plants.…
