Australian Wildfires Forced Cooling and Were the Main Variable in Climate Forcing in 2020 This Week in Review (1) House Adopts Bill Containing FY 2022 Appropriations for EPA (July 29, 2021) – By a vote of 219-208, the U.S. House of Representatives adopted H.R. 4502, which contains FY 2022 appropriations for a host of federal agencies, including EPA. It calls for $320 million in grants to state and local air agencies under Sections 103 and 105 ($90.5 million above FY 2021 levels); $11.34 billion for EPA’s total budget (approximately $2 billion above FY 2021 levels); $150 million for grants under the Diesel Emissions Reduction Act (DERA) ($60 million above FY 2021 levels); $71 million for Targeted Airshed Grants ($12 million above FY 2021 levels); zero for Multipurpose grants (which were $10 million in FY 2021); $100 million for six new Environmental Justice grant programs; and retention of PM 2.5 monitoring grants under Section 103 authority (the Administration’s request called for shifting it to Section 105 authority). Consideration of the bill on the House floor included votes on numerous amendments introduced by both
2 Democrats and Republicans. Among those that were adopted included an increase of $1 million for the Civilian Climate Corps, a transfer of $1 million from the Department of Interior to EPA’s Targeted Airshed Grants and an amendment intended to highlight advances in sensor technology for mobile air quality monitoring and to encourage EPA to focus on continuing to integrate this technology. Among the amendments that were voted down were measures that attempted to eliminate funding for EPA’s Criminal Enforcement Division, the Administration’s executive order to address climate change, DERA, the oil and natural gas rule, the Civilian Climate Corps and new environmental justice programs. Other rejected amendments would have reduced overall funding by 20 percent and environmental justice training and implementation grants by $100 million. The Senate has not yet acted on FY 2022 appropriations legislation so it is highly likely Congress will need to adopt a continuing resolution to keep the federal government in operation after the new fiscal year begins on October 1, 2022.

Reg. 40,825) a notice announcing a proposed consent decree reached with plaintiffs in a case alleging that EPA failed to perform its nondiscretionary duty under the Clean Air Act (CAA) to take final action on certain infrastructure State Implementation Plans (SIPs) for the 2015 National Ambient Air Quality Standards for ozone. The plans, also referred to as “Good Neighbor SIPs,” are required under Section 110 of the CAA and must “contain adequate provisions prohibiting . . . any source or other type of emissions activity within the State from emitting any air pollutant in amounts which will contribute significantly to nonattainment in, or interfere with maintenance by, any other State with respect to any such [NAAQS].” The SIPs in question were submitted by Indiana, Kentucky, Michigan, Ohio, Texas, and West Virginia but EPA never approved or disapproved them, in whole or in part. Downwind states New York, Connecticut, Delaware, Massachusetts and New Jersey, as well as the City of New York, sued EPA on January 12, 2021, in the U.S. District Court for the Southern District of New York. The proposed consent decree includes specific deadlines by which EPA would need to act on these six SIP submissions. Comments on the proposed consent decree are due to EPA by August 30, 2021.

3 tools to better understand the disproportionate impacts of air pollution from power plants on overburdened communities. This mapping tool, made available through EPA’s Power Plants and Neighboring Communities initiative, improves access to power plant emissions data and highlights the demographics that might be affected and how. Six key population groups of communities within three miles of a power plant are tracked and compared to the rest of the nation: low-income, people of color, those with less than high school education, those who are linguistically isolated, children under five years of age and adults over the age of 65. In addition to providing explanatory text, supplemental graphs and maps and data sets, the resource advises state and local policymakers on how to use the information to protect their most vulnerable populations. Data from more than 3,400 fossil fuel-fired power plants are included in the resource. EPA Administrator Michael S. Regan said of this new tool, “We know air pollution affects some people worse than others. Achieving environmental justice starts with improving our understanding of the impacts of air pollution, especially in overburdened and historically underserved communities. This web resource equips users with actionable, science-based data on air quality in communities near power plants, many of whom are suffering the worst from pollution.” For further information: https://www.epa.gov/airmarkets/power-plants-and-neighboring- communities (4) Markey Introduces Bill to Fund “Hyperlocal” Air Quality Monitoring and Mapping to Address Environmental Justice Hotspots (July 27, 2021) – Senator Edward Markey (D-MA), Chair of the Environment and Public Works Committee, introduced legislation that would direct $100 million a year to enable state, local and tribal air agencies to partner with nonprofit organizations to conduct hyperlocal air quality monitoring, in order to identify and address persistent elevated levels of air pollutants in environmental justice communities. The “Environmental Justice Air Quality Monitoring Act of 2021” is co-sponsored by Senators Kirsten Gillibrand (D-NY), Alex Padilla (D-CA), Richard J. Durbin (D-IL), Cory A. Booker (D-NJ), Tina Smith (D-MN), Bernie Sanders (I-VT) and Tammy Duckworth (D-IL). The bill would establish a five-year pilot program to award competitive grants to air agencies and their partner organizations. Projects eligible for funding would carry out air quality monitoring that yields frequently repeated, ongoing measurements of air pollutants at a block-level resolution and identify areas of persistent elevated air pollution levels above relevant background levels. The projects would also generate “equity maps” using data related to factors such as race, ethnicity and income level, and mapping tools that would make this information available to communities and air agencies. “The continuing respiratory pandemic has shed light on the deep-rooted injustices of air pollution in communities across our country. Black, Brown, and low-income families have for too long been overburdened by the dirtiest air without enough federal support to address it,” Senator Markey said in a statement. “But we can’t manage what we don’t measure, and one size does not fit all from block to block. With more air quality monitors to capture hyperlocal data and inform pathways to reduce pollution in these hotspots, we can help ensure that healthy air is no longer

Although the $1 trillion proposal is smaller than the $2.3 trillion plan originally proposed by the White House, the deal would provide $550 billion in new federal money for public transit, roads, bridges, water and other physical projects over the next five years. Senators voted 67-32 to proceed with the bill, with contains the text of several bipartisan bills including the Environment and Public Works Committee’s highway bill, (S. 1953); the Commerce, Science and Transportation Committee’s rail bill, (S. 2016); the Energy and Natural Resources Committee’s energy bill (S. 2377); among others. A White House release about the bipartisan deal touted a number of investments aimed at reducing greenhouse gas (GHG) emissions. “The deal’s $73 billion investment is the single largest investment in clean energy transmission in American history. It upgrades our power infrastructure, including by building thousands of miles of new, resilient transmission lines to facilitate the expansion of renewable energy” the factsheet says, and “invests in demonstration projects and research hubs for next generation technologies like advanced nuclear reactors, carbon capture, and clean hydrogen.” While the largest single expenditure is $110 billion in new funding for roads, bridges and other major projects, the White House noted that this would be spent with a “focus on climate change mitigation”. It also proposes $39 billion for transit but cuts support for electric school buses to $2.5 billion from the $7.5 billion originally included in the framework, and includes only $7.5 billion for electric vehicle charging stations, far lower than the President’s proposed $174 billion for electric vehicles and supportive infrastructure. The legislative package must still be approved by the full U.S. Senate and undergo reconciliation with a companion bill in the U.S. House of Representatives. Democrats have signaled their intent to pass both the bipartisan deal and a separate $3.5 trillion budget resolution to launch the reconciliation process for other Democratic priorities before the August Senate recess.

ENRD is the DOJ litigating component charged with enforcing the nation’s environmental laws and defending the Biden administration’s environmental regulations in court. Kim had been serving since January as deputy general counsel for the Department of Energy. He previously spent seven years as an ENRD appellate lawyer during the Clinton and George
5 W. Bush administrations. He then served for eleven years as the first solicitor general for the District of Columbia, followed by three years in private practice at Reed Smith LLP. In 2014, Kim was nominated by President Obama to be a judge on the U.S. Court of Appeals for the District of Columbia Circuit, but the Senate never acted on that nomination. Following Kim’s confirmation as Assistant Attorney General for ENRD, Senator Dick Durbin (D-IL), Chair of the Senate Judiciary Committee, released the following statement: “With Mr. Kim leading ENRD, the American people can trust that our nation’s public lands and natural resources will be protected by a proven expert in environmental law – and an accomplished lawyer who knows the Division inside and out. I look forward to working with Mr. Kim on these efforts.” For further information: https://www.congress.gov/nomination/117th-congress/250 (7) Ten States Ask Court to Block Biden Administration’s Interim Social Cost of Carbon (July 27, 2021) – A coalition of ten states led by Louisiana filed a motion asking the U.S. District Court for the Western District of Louisiana to issue a preliminary injunction (PI) prohibiting the federal government from implementing the interim social cost of greenhouse gases (SC-GHG) (also referred to as the “social cost of carbon”) developed pursuant to President Biden’s January 20, 2021 Executive Order (EO) 13990. The SC-GHG is an analytical tool used in regulatory decision-making to estimate the monetized damages associated with incremental increases in greenhouse gas emissions. EO 13990 established an interagency working group tasked with developing an interim SC-GHG within 30 days. In March, the group endorsed raising the SC-GHG to $51 per ton (under the Trump Administration, it had fallen to $1 per ton). In their PI motion and accompanying memorandum of law, the plaintiff states asset that the interim SC-GHG metric “may be the most significant regulatory encroachment upon individual liberty and State sovereignty in American history.” They claim that the President and the working group lacked authority to promulgate and enforce the SC-GHG estimates, that it contravenes several statutes (including the Clean Air Act), and that its promulgation violated federal rulemaking requirements. The state plaintiffs in this lawsuit (Louisiana v. Biden, W.D. La. No. 2:21-CV-1074-KDC-KK), which was filed in April, are Louisiana, Alabama, Florida, Georgia, Kentucky, Mississippi, South Dakota, Texas, West Virginia and Wyoming. A similar lawsuit was filed by a coalition of twelve states in the U.S. District Court for the District of Missouri in March.

Regan 113 members of the U.S. House of Representatives urge prompt reinstatement of the Clean Air Act (CAA) waiver previously granted for California’s Advanced Clean Cars (ACC) program. In 2013, EPA granted California’s request for a waiver of federal preemption for the state’s
6 ACC program under CAA Section 209, allowing California to enforce its program. Under CAA Section 177, other states were then authorized to adopt and enforce this program as well, which many have done. In September 2019, under the Trump Administration, EPA withdrew the waiver for two components of the ACC program – the greenhouse gas emission standards and the Zero-Emission Vehicle standards. As the legislators write in their letter, “The withdrawal of the waiver by the Trump Administration was unprecedented, and because it was based on erroneous interpretations of the Energy Policy and Conservation Act, as amended by the Energy Independence and Security Act, and the Clean Air Act, it was unlawful. EPA has never previously withdrawn a waiver, and we believe the agency lacks the authority to do so. However, even if EPA did have such authority, there was not a proper basis for doing so in this case.” On April 28, 2021, pursuant to an Executive Order issued by President Joe Biden upon taking office in January 2021, EPA published a notice in the Federal Register (86 Fed. Reg. 22,421) seeking comment to inform its reconsideration of the waiver withdrawal. The comment period for responses to the solicitation closed on July 6. As further action is awaited, the congressmen write, “The waiver provides important benefits to the entire nation. By enabling states to adopt standards to protect residents’ public health and welfare, the waiver has spurred significantly greater innovation and development of cleaner vehicle technologies. Similarly, California and other states’ adoption of its zero-emission vehicle program has been critical to fostering the development and introduction of electric vehicles, which are now available everywhere and reduce both pollution and fuel expenses for all Americans. These regulatory programs lead to life-saving air quality improvements, which is especially critical for people of color and low-income communities, who experience disproportionate harm from motor vehicle pollution. The mounting threats to health and welfare posed by climate change makes [sic] the authority of the states to lead more important than ever. It is vital that the waiver be reinstated to allow pioneering states to continue the process of innovation in clean vehicles.” For further information: https://matsui.house.gov/uploadedfiles/2021.07.27._epa_letter_re_reinstating_cle an_cars_waiver_ecc.pdf (9) Senators Seek Meeting with President Biden to Discuss Role of RFS in Energy and Climate Agenda (July 28, 2021) – Nine Senators sent a letter to President Joe Biden asking to meet with him to discuss the renewable Fuel Standard (RFS) and how biofuels can play a key role in the nation’s energy and climate agenda: “…we seek an audience to discuss the tremendous opportunity that biofuels like ethanol and biodiesel present to bolster affordable American energy, underpin a strong agricultural economy, and immediately lower transportation emissions using the existing consumer vehicle fleet and fueling infrastructure. Unfortunately, the promise of homegrown biofuels and our agriculture sector appear [sic] to be woefully underrepresented in your administration’s energy, environmental, and transportation agenda.” In particular, the Senators write that they would like to discuss “immediate and intermediate” steps that can be taken, including the “foundational” actions of directing EPA to adopt modern greenhouse gas modeling for renewable fuels and approving “long-
7 stalled” registrations for advanced, cleaner fuels. The Senators also identify several other actions they believe the Administration should take, including formally recognizing the reduced carbon emissions of American biofuels and enabling greater use of advanced biofuels in the U.S. market to promote expanded export opportunities, writing “[h]omegrown, American biofuels are a prime candidate for reducing our trade deficits…” They also recommend that the Administration maximize near-term emission reductions by supporting biofuel blending infrastructure, and rigorously implement and enforce the RFS.” The nine Senators who signed the letter are John Thune (R-SD), Chuck Grassley (R-IA), Roy Blunt (R-MO), Jerry Moran (R-KS), Deb Fischer (R-NE), Mike Rounds (R-SD), Joni Ernst (R-IA), Ben Sasse (R-NE) and Roger Marshall (R-KS).

The “100% Clean Energy for All Act” (HB 2021), which passed in Oregon's Senate 16-12 and in the House 35-20, requires Oregon’s investor owned utilities, Portland General Electric and Pacific Power, to submit plans to reduce GHG emissions by 80% from a baseline amount by 2030, 90% by 2035 and 100% by 2040. Seventeen other states and the District of Columbia have already adopted similar goals, but Oregon's has the earliest compliance date. It also prohibits the state from permitting new or expanded fossil fueled power infrastructure, includes labor provisions like apprenticeship training requirements, and establishes $50 million in community-based renewable energy
8 project grants.

These clean cars standards are a win across the board. With cleaner air, more car options, economic growth, and less money spent on foreign oil, every Minnesotan will benefit,” said Governor Walz. With this action, Minnesota becomes the fifteenth state to adopt clean car standards. The plan requires automakers to meet both Low-Emission Vehicle standards and Zero-Emission Vehicle Standards beginning with the 2025 model year.

The research and development (R&D) projects receiving grants seek to reduce carbon dioxide emissions from passenger cars and light- and heavy-duty trucks. DOE’s intent is for these R&D projects to contribute to the decarbonization of the transportation sector and enhancement of the infrastructure necessary to support the expanding adoption of ZEVs, which is a critical component of reaching the Administration’s goal of a net-zero emissions economy by 2050. Each of the 24 projects focus on one of the following: 1) accelerating innovation in electric vehicle batteries and electric drive systems, 2) readying new mobility systems technology for commercial and consumer use, 3) developing lightweight materials to increase passenger and commercial vehicle efficiency, 4) reducing exhaust emissions while improving commercial vehicle engine efficiency or 5) improving understanding of energy use and environmental impact of new vehicle technologies.

Speaking at a hearing conducted by the U.S. House of Representatives Energy and Commerce Committee, FERC Commissioner Allison Clements said that roughly 93% of 750 GW of power projects now waiting for transmission interconnections are for renewable energy. FERC Chairman Richard Glick highlighted FERC’s current Advance Notice of Proposed Rulemaking seeking public comment on reforms to improve transmission planning and interconnection processes as the U.S. transitions to cleaner energy sources. Committee Chairman Frank Pallone (D-NJ) pressed the witnesses on progress to organize offshore wind energy projects; Rep. Cathy Rodgers (R-WA) also reminded FERC to manage reliability related to intermittent power sources that could "take America back to the Dark Ages.” Rep. Gary Palmer, (R-AL.) raised energy affordability concerns, asking “Does it make sense to deprive people of energy justice to promote clean energy?” FERC Commissioner Neil Chatterjee said carbon pricing is the superior approach to the clean energy transition. “My regulatory philosophy is that the Commission should never be a barrier to progress,” he said. Asked by Rep. David McKinley (R-WV), how FERC will consider cumulative impacts of GHG emissions under its federal NEPA reviews of fossil gas pipelines and infrastructure, FERC Chairman Glick said the agency currently cannot take those emissions into consideration but will continue to consider GHG emissions directly from the infrastructure being permitted. He also noted that FERC would increase its focus on impact to vulnerable communities, saying that “it is essential that environmental justice and equity get the attention in our decision-making processes that they deserve.” For further information: https://energycommerce.house.gov/committee- activity/hearings/hearing-on-the-changing-energy-landscape-oversight-of-ferc (16) Australian Wildfires Forced Cooling and Were the Main Variable in Climate Forcing in 2020 (July 26, 2021) - the authors of research published in the journal Geophysical Research Letters have concluded that the overall effect of the COVID-19 pandemic was a slight increase in global average temperatures in 2020, but that this effect was dwarfed by aerosol-induced cooling caused by wildfires in Australia that year. “The main climate forcing of 2020 wasn’t COVID-19 at all,” according to an accompanying press release quoting the authors of the new study, “It was the explosion of wildfires in Australia.” The study found that the lockdowns associated with COVID-19 resulted in fewer clouds and a lower planetary albedo reflecting sunlight before it could be absorbed at the Earth’s surface, resulting in a slight warming influence on global climate, but that this was offset by a much larger wildfire effect. “In contrast, the simulated response to Australian wildfires is a strong and rapid cooling” in the Southern Hemisphere, the
10 study concluded. Wildfire emissions of sulfates and other particles resulted in clouds reflecting more sunlight to space before absorption at the surface. This result will be short-lived however, given that GHG emissions from the fires will lead to increased global heat trapping by the atmosphere, and a warming effect in the medium- and long-terms.
