Washington AG Challenged U.S. Navy’s Failure to Adequately Assess Noise Impacts of Increased Growler Jet Operations
Washington Attorney General Bob Ferguson sued the U.S. Navy over its failure to sufficiently analyze the noise impacts of its recent decision to increase operations of EA-18G Growler jets at Naval Air Station Whidbey Island. In the complaint, Attorney General Ferguson warned that the increased activity will “significantly impact the people, landscape, and wildlife of Whidbey Island and the broader region,” and will “adversely affect public health, public schools, and historic areas” as well as local populations of birds, land animals and marine species. Attorney General Ferguson asserted that the Navy’s environmental impact statement failed to meet the National Environmental Policy Act’s requirements that federal agencies take a “hard look” at the impacts of their proposed actions on public health and wildlife, and consider appropriate measures to mitigate those impacts. Attorney General Ferguson also asserted that the Navy violated the National Historic Preservation Act by failing to “make a reasonable and good faith effort” to mitigate the adverse impacts of increased jet activity on the Central Whidbey Island Historic District and Ebey’s Landing National Historical Reserve.

Eleven AGs Challenged EPA’s Refusal to Protect Public Health by Strengthening Asbestos Reporting Requirements
Massachusetts Attorney General Maura Healey and California Attorney General Xavier Becerra led a coalition of 11 attorneys general in suing the Environmental Protection Agency (EPA) over its denial of the states’ January 2019 petition to close loopholes in the agency’s data reporting requirements for asbestos. In their complaint, the attorneys general noted that the EPA’s decision to deny their petition violates its statutory obligations under the Toxic Substances Control Act’s Chemical Data Reporting rule, which requires the agency to fully evaluate and mitigate the risks associated with toxic substances that pose a known danger to human health and the environment. The petition would have forced the EPA to address a significant loophole in its current asbestos data reporting requirements that applies to the majority of asbestos-containing materials that are imported into the United States. The provision of this data would be consistent with the “right to know” intent of the Toxic Substances Control Act, and would provide states with critical information needed to keep their communities safe.

Washington AG Sued EPA Over Weakening of State Water Quality Standards
Washington Attorney General Bob Ferguson sued the Environmental Protection Agency (EPA) over the agency's May 2019 decision to unilaterally weaken Washington’s water quality standards over the objection of AG Ferguson and Washington Department of Ecology Director Maia Bellon. In the complaint, AG Ferguson noted that the EPA's changes to the state’s water quality standards violate the Clean Water Act, which allows the EPA to revise state water quality standards only if the agency determines that current standards are not stringent enough to protect human health, or if the standards submitted by a state do not meet the applicable requirements of the statute. AG Ferguson asked the court for a declaration invalidating and vacating the EPA's decision, and for an injunction preventing the agency from making any future attempts to unlawfully revise Washington’s water quality standards.

New York AG Challenged FERC’s Approval of Northern Access Pipeline
New York Attorney General Letitia James filed a petition in the U.S. Court of Appeals for the Second Circuit seeking review the Federal Energy Regulatory Commission’s (FERC) August 2018 order finding that the state waived its Clean Water Act certification authority for National Fuel’s Northern Access pipeline. The New York Department of Environmental Conservation (NYDEC) received an application for certification of the project under Section 401 of the Clean Water Act in March 2016, and subsequently entered into an agreement with National Fuel to revise the date of receipt to April 2016. In April 2017, within the one-year statutory limit for state review, NYDEC denied certification for the project. However, in August 2018, FERC sided with Natural Fuel and found that NYDEC exceeded the one-year limit and waived its certification authority, and subsequently denied NYDEC’s request for rehearing. In the petition for review, AG James argues FERC’s waiver order and rehearing denial should be “set aside in whole as illegal, unreasonable, arbitrary and capricious.”

New Hampshire AG Sued Manufacturers and Sellers of PFAS Products
New Hampshire Attorney General Gordon MacDonald filed a lawsuit against eight chemical companies over per- and polyfluoralkyl substance (PFAS) contamination resulting from the manufacture and sale of firefighting foam, and an additional lawsuit against DuPont, Chemours and 3M over the manufacture and sale of other products containing PFAS. In the lawsuits, AG MacDonald alleges that the companies continued to manufacture and sell products containing PFAS despite being aware of the persistent and bioaccumulative nature of the chemicals. The lawsuit seeks repayment for the costs of remediation, as well as “enhanced compensatory damages” on the grounds that the companies’ actions were "committed intentionally, wantonly, maliciously and/or oppressively." AG MacDonald expressed hope that the companies named in the lawsuit “will recognize the severity of the issues they've caused and will become part of the solution.”

New Jersey AG Sued Manufacturers and Sellers of PFAS Products
New Jersey Attorney General Gurbir Grewal filed a lawsuit against eight companies — including 3M, DuPont and Chemours — over the manufacture and sale of firefighting products containing harmful per- and polyfluoralkyl substances (PFAS). In the lawsuit, AG Grewal alleges that the companies produced, advertised and sold aqueous film-forming foam products for decades despite knowing that they contained hazardous PFAS chemicals. The lawsuit explains the severe public health and environmental threat posed by PFAS chemicals, and emphasizes that the contaminants “are mobile, persist indefinitely in the environment, bioaccumulate in individual organisms and humans, and biomagnify up the food chain.” The lawsuit seeks payment for the costs of a full investigation and remediation and restoration efforts, as well as natural resource damages and other penalties.

North Carolina Filed Brief to Protect Ratepayers from Coal Ash Cleanup Costs
North Carolina Attorney General Josh Stein filed a brief with the North Carolina Supreme Court requesting the court overturn the North Carolina Utilities Commission’s decision to allow Duke Energy to pass the costs of its coal ash cleanup obligations on to ratepayers. In his brief, Attorney General Stein noted that Duke Energy had knowingly violated state law for years by continuing to dump coal ash in unlined ponds, and that the Utilities Commission had erred when it allowed the company’s subsidiaries (Duke Energy Progress and Duke Energy Carolinas) to receive hundreds of millions of dollars in profit by charging ratepayers for cleaning up its own pollution. Attorney General Stein noted that the cleanup costs are the direct result of Duke Energy’s own mismanagement and unlawful conduct, and should therefore be borne by shareholders, not ratepayers.

New York Sued EPA Over Failure to Regulate Cross-State Ozone Pollution
New York Attorney General Letitia James filed a lawsuit challenging the EPA’s failure to regulate ozone pollution from upwind states. The suit followed the EPA’s failure to respond to a petition filed by New York in March 2018, pursuant to the “Good Neighbor” obligations set forth under Section 126(b) of Clean Air Act, in which New York identified power plants in nine states whose nitrogen oxide (NOx) emissions prevented the New York Metropolitan Area from attaining 2008 and 2015 National Ambient Air Quality Standards (NAAQS) for ozone. In the lawsuit, Attorney General James noted that the state’s persistently unsafe levels of ozone pollution regularly compromises the health and welfare of more than 12 million New Yorkers living in the New York Metropolitan Area, and on particularly bad days can affect as many as 16 million residents of her state.

California Sued EPA and NHTSA for Withholding Data on Clean Car Standards 
California Attorney General Xavier Becerra sued the EPA and the National Highway Traffic Safety Administration (NHTSA) over the agencies’ inadequate responses to a Freedom of Information Act (FOIA) request for critical information related to the administration’s proposal to roll back national Clean Car Standards. Noting the unprecedented decision to withhold their underlying analysis from the public prior to moving forward with a new rulemaking, regulators at the California Air Resources Board (CARB) requested documents from both federal agencies concerning their analysis of “vehicle fleet composition, new car sales, vehicle safety, battery technology, and other information that NHTSA and EPA used in proposing to roll back vehicle emission and fuel economy standards.” In the state’s new lawsuit, filed by AG Becerra on behalf of CARB, California is alleging that the EPA failed to make timely determinations on CARB's September 2018 FOIA request and that the NHTSA failed to adequately justify its decision to withhold the requested material.

Challenged Unconstitutional “2-For-1” Executive Order
California Attorney General Xavier Becerra, Minnesota Attorney General Keith Ellison, and Oregon Attorney General Ellen Rosenblum filed a lawsuit seeking an injunction against President Trump’s “Two-for-One” Executive Order requiring federal agencies to repeal two existing regulations for every new regulation that is legally promulgated. The Order has been used to justify the attempted rollback of environmental regulations that were put in place in response to federal agencies’ statutory obligations under bedrock environmental laws such as the Clean Air Act, Clean Water Act and the Toxic Substances Control Act.

In their complaint, the attorneys general asked the court to find the order unconstitutional, noting that it violates the Constitution’s separation of powers doctrine by requiring agencies to repeal two congressionally-authorized rules for every new congressionally-authorized rule that agencies issue — regardless of the agencies’ independent statutory obligations to implement Congressional directives.

New Jersey Sued Chemical Companies Over Hazardous Waste Dumping
New Jersey Attorney General Gurbir Grewal filed four natural resource damage lawsuits against DuPont, Chemours and 3M. AG Grewal alleges that the companies violated New Jersey’s Water Pollution Control Act and its Spill Compensation and Control Act, while simultaneously misleading the public about the dangers associated with the dumping of hazardous chemicals in the state. Two of the complaints focus on the companies’ use of PFAS (per- and polyfluoroalkyl substances), an emerging environmental and public health issue. The other two complaints concern contamination of groundwater, surface water and other natural resources with volatile and semi-volatile organic compounds, mercury, lead and other contaminants.

Washington Intervened in Lawsuit Against U.S. Navy Over Clean Water Act Violations in Puget Sound
Washington Attorney General Bob Ferguson filed a motion to intervene in ongoing litigation brought by environmental groups and a Native American tribe challenging the U.S. Navy’s release of pollutants into the Puget Sound. The lawsuit alleges that the Navy released the equivalent of fifty dump truck loads of pollutants, including copper and zinc, into the Sound when it scraped the hull of a ship in January 2017. Copper and zinc are highly toxic to marine life, and the Navy lacked a permit to lawfully discharge the pollutants into the Sound.

New Jersey Sued ExxonMobil Over Illegal Dumping of Hazardous Waste
New Jersey Attorney General Gurbir Grewal filed a lawsuit against ExxonMobil for contamination stemming from "industrial dumping activity" at the company's 12-acre Lail property in Gloucester County, NJ. The lawsuit alleges that beginning in the 1950s, ExxonMobil "used the Lail property to dispose of drums containing petroleum products and other hazardous substances,” resulting in contamination of wetlands and waterways. Despite the removal of drums in the 1990s and remediation efforts in the late 2000s, recent inspections detected the presence of polychlorinated biphenyls (PCBs), a class of chemicals known to cause reproductive, developmental, respiratory and dermatological issues in humans and animals. The lawsuit seeks natural resource damages for ongoing testing and remediation efforts.

The complaint alleges that the U.S. Air Force has sprayed firefighting foam containing per- and polyfluoroalkyl substances (PFAS) on the ground and tarmacs in fire training and actual firefighting events at the New Mexico bases for more than 50 years, allowing PFAS to seep into the surrounding groundwater in violation of the New Mexico Hazardous Waste Act. New Mexico is seeking injunctive relief requiring abatement of ongoing violations of the Act and a permanent injunction for the Air Force to take all steps necessary to achieve permanent and consistent compliance with the Act.

Filed a Motion to Intervene in Lawsuit Over EPA’s Rollback of Air Toxic Compliance Requirements for Cement Plants
California Attorney General Xavier Becerra and Illinois Attorney General Lisa Madigan filed a motion to intervene in Downwinders at Risk v. EPA, a lawsuit brought against an EPA rule finalized in July 2018 severely weakening existing air toxic compliance requirements for portland cement plants. The AGs noted that, instead of meeting its statutory obligations under section 112(d)(6) to review the Agency’s industry specific standards for hazardous air pollutants and propose new technology-based emission standards mitigating public risk, the EPA’s final rule establishes a regulatory loop-hole allowing cement kiln operators to evade emissions standards through periodically shutting down their operations.

The AG’s note that the EPA’s new six-month compliance holiday for cement kiln operators can be applied to any shutdown event, allowing operators to space out shutdown events periodically to avoid any future compliance with existing emissions standards. The AGs also noted that disadvantaged communities bear the greatest exposure to hazardous air pollution from cement kilns, which emit dangerous carcinogens and neurotoxins including mercury, lead, arsenic, cadmium, and dioxins.

Sued the EPA Over Failure to Regulate NOx Emissions from Neighboring States
Maryland Attorney General Brian Frosh sued the EPA in the U.S. Court of Appeals for the D.C. Circuit for its refusal to require power plants in neighboring states to reduce nitrogen oxide emissions. Maryland initially petitioned the EPA to regulate nitrogen oxide emissions in nearby states in November 2016 under the Clean Air Act. In its petition, Maryland noted that out-of-state nitrogen oxide is a precursor to the dangerous levels of ozone that plague the State in the hot summer months. In June 2018, a Maryland federal judge ordered the EPA to make a final decision on Maryland’s 2016 petition, which the EPA subsequently denied in September. Maryland is suing the EPA over the denial of its petition to protect residents of the state from the negative health consequences of out-of-state pollution.

UPDATE: On November 5, Delaware Attorney General Matthew Denn submitted a Petition to Review over the EPA’s decision to deny its four petitions to regulate ground-level ozone pollution from neighboring states. On December 4, New York and New Jersey filed a Motion to Intervene in the litigation, which has subsequently been granted.

Filed Suit Over Administration’s Repeal of the Methane Waste Prevention Rule
California Attorney General Xavier Becerra and New Mexico Attorney General Hector Balderas filed suit against the Trump Administration on September 18 over the Administration’s decision to dismantle the Obama-era Methane Waste Prevention Rule. In their lawsuit, the attorneys general called the Methane Waste Prevention Rule “a commonsense measure” that would “reduce the enormous waste of natural gas on public lands that results from venting, flaring, and equipment leaks.” The AGs also noted that the Administration’s rollback of the rule comes in the wake of its attempt to “illegally delay and suspend its implementation.” 

“With this attempt to axe the Waste Prevention Rule, the Trump Administration risks the air our children breathe and at taxpayers’ expense,” said Attorney General Becerra. “We’ve sued the Administration before over the illegal delay and suspension of this rule and will continue doing everything in our power to hold them accountable for the sake of our people and planet.”

Submitted Petition to Review for the EPA’s Mercury Inventory Rule
Vermont Attorney General T. J. Donovan submitted a petition for review to the U.S. Court of Appeals for the Second Circuit for the EPA’s “Mercury; Reporting Requirements for the TSCA Mercury Inventory” rule. The EPA is required to develop mercury reporting regulations under the Toxic Controlled Substances Act (TSCA), which directs the Agency to create a comprehensive inventory of mercury “supply, use and trade” in the United States. The EPA’s final rule exempts companies from reporting industrial mercury use if those companies are already reporting under TSCA’s Chemical Data Reporting requirements, which critics argue violates Congress’s clear intent under the law, and will lead to an incomplete and outdated inventory of mercury.

Eight attorneys general sued the Interior Department, the U.S. Fish and Wildlife Service and Interior’s Acting-Solicitor Daniel Jorjani over the Trump Administration’s decision to reverse decades of regulatory precedent related to the Migratory Bird Treaty Act (MBTA). The AGs brought their suit in the U.S. District Court for the Southern District of New York, and are asking the court to vacate what is known as the Jorjani Opinion, a December 2017 Solicitor’s Opinion reinterpreting the scope of the MBTA.

The AGs’ suit argues that the Administration’s new interpretation of the MBTA is inconsistent with the legislative intent of the MBTA to prohibit the unintentional harming of migratory birds, and is an arbitrary and capricious regulatory action in violation of the Administrative Procedures Act.

A coalition of 16 Attorneys General filed a lawsuit against the EPA for the Agency’s suspension of its 2016 Glider Truck Rule. In its press release announcing the suite, California Attorney General Xavier Becerra said that EPA’s decision is dangerous to human health and the environment. “The EPA itself has estimated that adding 10,000 gliders with non-compliant engines onto our roads in a single year could result in up to 1,600 premature deaths, 415,000 tons of additional nitrogen oxide emissions, and 6,800 tons of additional particulate matter emissions over the lifetime of those trucks. We look forward to making our case in court and to holding the EPA accountable for its blatant violation of our laws.”

The suit advances eight claims against the fossil fuel companies for producing, promoting and marketing of fossil fuel products, while concealing the known hazards of their products. AG Kilmartin alleged that the 21 companies were directly responsible for the release of hundreds of gigatons of carbon dioxide emissions between 1965 and 2015 that have caused harm that Rhode Island has experienced and will continue to experience in the future. The severe harms include substantial sea level rise, more frequent and severe flooding, extreme precipitation events and drought.

Attorneys general filed suit against the Bureau of Land Management (BLM) "over its decision to suspend the Waste Prevention Rule. The Rule went into effect on January 17, 2017 but was illegally suspended by the Trump Administration on December 8, 2017. The Rule requires oil and natural gas producers to cut wasteful leakage of methane on federal lands. In the lawsuit, Attorneys General Becerra and Balderas underscored that suspending key provisions of the Rule would be arbitrary and capricious as well as contrary to BLM's statutory mandate to prevent waste and ensure the safe and responsible development of oil and gas resources on public lands."

Filed Lawsuit To Protect Fuel Efficiency Standards Rule
In the 2nd Court of Appeals in New York City, attorneys general sued the National Highway Traffic Safety Administration "for illegally delaying a rule that encourages automakers to produce vehicle fleets that meet or exceed federal fuel efficiency standards.Set to take effect in July 2017, the rule would increase the penalty imposed on automakers whose vehicle fleets do not meet minimum fuel efficiency standards. All federal agencies were required to increase their civil penalty rates by an act of Congress, the 2015 Federal Civil Penalties Inflation Adjustment Act. In response, the U.S. Department of Transportation issued a new rule to increase the penalty by $8.50 per tenth of a mile per gallon. The Trump Administration has delayed it, reverting back to the lower penalty rate instead. If the penalty is not sufficiently high, automakers lack a vital incentive to manufacture fuel efficient vehicles."
