On December 18, 2020, U.S. EPA issued its long awaited draft interim guidance on disposal and destruction methods for per- and polyfluoroalkyl substances (PFAS). The guidance, which U.S. EPA was required to issue pursuant to the National Defense Authorization Act for Fiscal Year 2020, discusses three disposal/destruction technologies—thermal treatment, landfilling and underground injection.
In discussing these technologies, the guidance acknowledges that it does not address what concentrations of PFAS in wastes, spent products, or other materials or media would necessitate destruction or disposal, noting that other regulatory mechanisms or risk based guidance are more appropriate for establishing such concentrations. Instead, the guidance is intended to provide information and suggested considerations to assist in evaluating destruction and disposal options for PFAS waste.
The guidance does not endorse any single technology—rather, the guidance generally discusses the following technologies in order of lower to higher uncertainty in terms of the ability to control the migration of PFAS into the environment during the disposal/destruction process.
- Interim Storage. Acknowledging that this is not a destruction or disposal method, the guidance notes that interim storage may be an option if the immediate destruction of the PFAS materials is not necessary. Interim storage (from two to five years) could be relied upon while research continues to minimize uncertainties associated with the other options.
Permitted Deep Well Injection (Class I). Underground injection would be limited to liquid-phase waste streams. However, the guidance notes that there are a limited number of wells and logistical issues could limit the practicability of this option.
- Permitted Hazardous Waste Landfills (RCRA Subtitle C). The guidance notes that RCRA Subtitle C landfills have the most stringent environmental controls in place and therefore have a higher potential to prevent the migration of PFAS into the environment.
Solid Waste Landfills (RCRA Subtitle D) with Composite Liners and Leachate Collection. These landfills can only receive non-hazardous wastes and therefore have less stringent environmental controls that vary from state to state.
Hazardous Waste Combustors. These consist of commercial incinerators and cement/aggregate kilns that can achieve temperatures and residence times sufficient to break apart the PFAS. However, the guidance notes that emissions from these combustion sources haven’t been adequately characterized to confirm that the PFAS compounds are in fact destroyed.
- Other Thermal Treatment. These consist of carbon reactivation units, sewage sludge incinerators, municipal waste combustors, and thermal oxidizers. However, the same uncertainties that were referenced in the previous bullet would also apply to these technologies.
The appropriate methodology for dealing with PFAS waste has been subject to controversy with environmental groups such as Sierra Club suing the Department of Defense (DoD) in an effort to prevent DoD from incinerating its stockpile of PFAS-based firefighting foams. Although U.S. EPA set a 60-day comment period on the interim guidance, U.S EPA could certainly elect to delay issuance of any final guidance to give the new Biden Administration an opportunity to put its imprint on the guidance )especially considering the emphasis that the new administration has placed on PFAS).
We will continue to track this guidance as well other PFAS-related issues on the Corporate Environmental Lawyer blog.
On December 7, 2020, EPA completed its five-year review of the National Ambient Air Quality Standards (“NAAQS”) for Particulate Matter (“PM”), a criteria air pollutant under the Clean Air Act. In a final action set to be published in the Federal Register in the coming days, EPA decided to retain the current NAAQS for PM, which have been in place since 2012.
PM is measured in two categories:
- Fine particles, or PM2.5, which are particles with a diameter of 2.5 micrometers and smaller; and
- Coarse particles, or PM10, which are particles with a diameters between 2.5 and 10 micrometers.
PM2.5, emitted from numerous sources including power plants, vehicle exhaust, and fires, is generally the more significant health concern, as it has been linked to serious respiratory disease, increased mortality rates, and recent studies have even linked a history of PM2.5 exposure to increased COVID-19 mortality rates.
The Clean Air Act requires EPA to set both primary and secondary NAAQS for PM2.5 and PM10. Primary NAAQS must be set at levels that will protect public health and secondary NAAQS must be set at levels that will protect public welfare. All NAAQS must be reviewed by EPA every five years. EPA has regulated PM emissions through the NAAQS since 1971, and revised the PM NAAQS four times since then—in 1987,1997, 2006 and 2012.
The current primary and secondary NAAQS for PM are as follows:
According to EPA data, there are currently 16 counties in the U.S. currently in nonattainment of the primary PM2.5 NAAQS and 23 counties currently in nonattainment of the primary PM10 NAAQS.
EPA’s decision to keep the existing PM NAAQS comes despite warnings from its own scientists. Notably, in the Policy Assessment for the Review of the National Ambient Air Quality Standards for Particulate Matter, one of the technical documents used by EPA in support of its final decision, EPA scientists concluded that:
“When taken together, we reach the conclusion that the available scientific evidence, air quality analyses, and the risk assessment…can reasonably be viewed as calling into question the adequacy of the public health protection afforded by the combination of the current annual and 24-hour primary PM2.5 standards.”
This Policy Assessment also states that under the current PM2.5 standards, long-term PM2.5 exposures are estimated to be associated with as many as 45,000 total deaths per year. However, the Policy Assessment also noted certain uncertainties and limitations in the evidence and risk assessments that could lead the agency to decide to keep the existing standards.
EPA received over 60,000 public comments on the PM NAAQS proposal, which was closely watched by environmentalists and industry alike. Because of this close public interest, this may be an issue that will be reviewed sooner than the normal five-year review once the Biden Administration begins in 2021. As always, we will keep you updated on any further developments at the Corporate Environmental Lawyer.

The Trump administration continues its efforts to issue new regulations in advance of January 20, 2021, with the Department of Energy (DOE) issuing a final rule that will exempt certain liquefied natural gas (LNG) projects from National Environmental Protection Act (NEPA) review. The final rule, published in the Federal Register on December 4, updates DOE’s NEPA implementing procedures with respect to authorizations issued under the Natural Gas Act in accordance with the recent revisions to the NEPA regulations as further described below.
According to DOE, the focus of the new rule is to clarify the scope of DOE’s NEPA obligations with respect to LNG projects and more specifically, to eliminate from the scope of DOE’s NEPA review potential environmental effects that the agency has no authority to prevent. Because DOE’s discretionary authority under Section 3 of the Natural Gas Act is limited to the authorization of exports of natural gas to non-free trade agreement countries, the rule limits the scope of environmental impacts that DOE must consider to the impacts associated with the marine transport of the LNG commencing at the point of export.
To that end, the final rule revises DOE’s existing Categorical Exclusions (CATEX) to reflect that the only elements of LNG projects subject to NEPA review is the following:
B5.7 Export of natural gas and associated transportation by marine vessel.
Approvals or disapprovals of new authorizations or amendments of existing authorizations to export natural gas under section 3 of the Natural Gas Act and any associated transportation of natural gas by marine vessel.
Based on prior NEPA reviews and technical reports, DOE has determined that the transport of natural gas by marine vessel normally does not pose the potential for significant environmental impacts and therefore qualifies for a CATEX. As such, the only reason that DOE would be obligated to engage in a NEPA review of a LNG project would be if “extraordinary circumstances” were deemed to be present that could not be mitigated and therefore would preclude DOE's reliance on this CATEX.
The revised CATEX also removes the reference to import authorizations from CATEX B5.7 because DOE has no discretion with respect to such approvals. Finally, the final rule also removes and reserves CATEX B5.8 and classes of actions C13, D8, D9 because these actions are outside of the scope of DOE’s authority or are covered by the revised CATEX B5.7.
Interestingly, although the Federal Energy Regulatory Commission (FERC) has responsibility for approving the construction of LNG export terminals, it has previously declined to analyze the greenhouse emissions associated with such projects, noting that DOE is the appropriate agency to consider such impacts. However, with DOE now concluding that these projects are categorically excluded from such reviews, it remains to be seen if FERC will reconsider its approach to these operations.
The final rule is scheduled to take effect on January 4, 2021 and it remains to be seen what if any action a new Biden administration might take in response to this rule. Assuming that the Republicans retain control of the Congress, DOE would be required to go through the formal withdrawal process. Alternatively, if the Democrats take control of the Senate, the regulation could be repealed pursuant to the Congressional Review Act.
We will continue to track the Trump administration’s ongoing effort to finalize regulations in advance of January 20th as well as efforts by any new administration to rollback these regulations on the Corporate Environmental Lawyer.

On the afternoon of November 30, 2020, the California Office of Administrative Law (OAL) issued the final approval, allowing the emergency COVID‑19 regulation proposed by the California Division of Occupational Safety and Health (Cal-OSHA) and approved by the California Occupational Safety and Health Standards Board (Board) on November 19. The emergency regulation, establishing new sections 3205, 3205.1 through 3205.4 to Title 8, Division 1, Chapter 4 (General Industry Safety Orders) of the California Code of Regulations (CCR) is titled “COVID‑19 Prevention.” The COVID‑19 Prevention Rule is attached here as approved by the OAL. The COVID‑19 Prevention Rule is immediately effective on November 30, 2020. As an emergency regulation, it expires by October 21, 2021, unless it is extended or made permanent.
California, which as a “state-plan State,” can adopt workplace safety and health regulations more stringent than US OSHA regulations and guidance, has through its emergency regulatory process adopted a COVID‑19 regulation that applies to “all employees and places of employment” in California, except if the employees are working from home, the place of employment has only one employee “who does not have contact with other persons,” or employees when covered by California’s Aerosol Transmissible Diseases regulation, 8 CCR § 5199, which applies only to health care services, facilities, and operations. 8 CCR § 3205(a)(1).
The basic construction of the COVID‑19 Prevention Rule follows the elements of California’s Injury and Illness Prevention Program (IIPP) rule, 8 CCR § 3203, and requires that all employers prepare and adopt a written program with the same elements of employee communication, hazard identification, inspections, hazard correction, training, controls, reporting, recordkeeping and access, but adds substantive requirements relating to COVID‑19 within each of those elements, and adds elements unique to an employer’s response to and control of COVID‑19. The COVID‑19 Prevention Rule also has provisions affecting aspects of an employer’s operations beyond its traditional safety and health scope, including an obligation to “continue and maintain an employee’s earnings, seniority and all other employee rights and benefits, including the employee’s right to their former job status, as if the employee had not been removed from their job” for employees who are otherwise able to work, but are excluded from the worksite for work-related COVID‑19 exposures and quarantines. 8 CCR § 3205(10)(C).
Other notable aspects of the regulation include:
- Definitions of COVID‑19 “exposure”, “symptoms”, “high-risk exposure period”, “exposed workplace”, periods of exclusion from the workplace (quarantine and isolation) and return-to-work criteria, that do not match the CDC’s current approach for essential workforces and which do not allow for any future changes in CDC guidelines regarding the length of isolation, quarantine, or return-to-work criteria.
- Employers must provide viral testing for all employees excluded under Cal-OSHA’s broad definition of “exposed workplace,” up to twice weekly depending on the severity of an outbreak at the workplace.
- Employers, with employee participation, must “conduct a workplace-specific identification of all interactions, areas, processes, equipment and materials that could potentially expose employees to COVID‑19 hazards.” 8 CCR § 3502 (c)(2)(D).
- Specific requirements regarding controls, including physical distancing, face coverings, ventilation, disinfection, cleaning, hygiene, PPE and engineering controls.
- Employers must provide notice within one business day of all COVID‑19 cases in the exposed workplace to employees “who may have had COVID‑19 exposures and [their union representative] and to all other employers/contractors in the workplace. 8 CCR § 3502 (c)(3)(B)3. (See also recently enacted revision to Labor Code § 6409.6 (AB 685).)
- Employers must communicate hazards, policies and procedures to employees and all “other employers, persons, and entities within or in contact with the employer’s workplace.” 8 CCR § 3502 (c)(1)(D)
- Specific requirements regarding COVID‑19 case investigation that must be documented and provided to any employee, employee representative, Cal-OSHA, or local health agencies.
- Employers must have a documented procedure for investigation of COVID‑19 cases in the workplace, with many specific steps required in the COVID‑19 Prevention Rule.
- Requirements for employer-provided transportation to and from the workplace and employer-provided housing. 8 CCR §§ 3205.3 and 3205.4.
Merely preparing the written program document, in addition to the required procedures and protocols, will be a significant undertaking for almost all California employers. In the public hearing before the Board, Cal-OSHA representatives minimized the additional burden placed on employers given its view that employers already should have already undertaken much of the effort to update their basic IIPP document. Cal-OSHA representatives stated, however, that it recognized that employers would have to take some time to get all the requirements in place and would exercise enforcement discretion given the regulation’s immediate effective date. Cal-OSHA also informed the Board that it planned to issue interpretive guidance and other materials, but did not specify a date by which it would do so. Cal-OSHA stated that it would hold Advisory Committee meetings with employers and employees regarding refining the Rule, but noted that the agency did not expect to propose any changes in the regulatory language in the near-term.
