Organizational Chart

Appellate Section

Jennifer Neumann, Section Chief

The Appellate Section’s work involves cases arising under the more than 200 statutes for which the Division has litigation responsibility. Section attorneys brief and argue appeals in all thirteen federal circuit courts of appeals around the country, as well as in State courts of appeals and supreme courts. The Section handles appeals in all cases tried in the lower courts by any of the sections within the Division; it also oversees or handles directly appeals in cases within the Division’s jurisdiction that were tried in the lower courts by U.S. Attorney Offices. The Section’s responsibility also includes petitions for review filed directly in the courts of appeals in environmental or natural resource cases involving the Department of Energy, the Federal Aviation Administration, the Federal Energy Regulatory Commission, the Nuclear Regulatory Commission, and the Surface Transportation Board. The Section works closely with Justice’s Office of the Solicitor General, making recommendations whether to appeal adverse district court decisions or to seek Supreme Court review of adverse appellate decisions. The Section writes draft briefs for the Solicitor General in Division cases before the Supreme Court.

Environmental Crimes Section

Deborah L. Harris, Section Chief

The Environmental Crimes Section is responsible for prosecuting individuals and corporations that have violated laws designed to protect the environment. It is at the forefront in changing corporate and public awareness to recognize that environmental violations are serious infractions that transgress basic interests and values. The Section works closely with criminal investigators for the Environmental Protection Agency (EPA), the Federal Bureau of Investigation (FBI), and the Fish and Wildlife Service (FWS) in dealing with violations of such statutes as the Clean Air Act, the Clean Water Act, the Resource Conservation and Recovery Act (RCRA), and the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA, more commonly known as Superfund), the Lacey Act, and the Endangered Species, among other statutes.

Environmental Defense Section

Letitia J. Grishaw, Section Chief

The Environmental Defense Section represents the United States in complex civil litigation arising under a broad range of environmental statutes. EDS is the only section in ENRD that routinely handles cases in both federal circuit and district courts. EDS defends rules issued by EPA and other agencies under the pollution control laws, brings enforcement actions against those who destroy wetlands in violation of the Clean Water Act, and defends the United States against challenges to its cleanup and compliance actions at Superfund sites, federally-owned facilities and private sites.

Examples of the Section’s work include: defending EPA’s regulations governing permitting of discharges from factory farms, its ambitious “Clean Air Interstate Rule” aimed at attaining air quality standards for ozone and fine particulate matter in the eastern half of the country, the Agency’s efforts to revamp the Clean Air Act new source review program, and its safety standards for the Yucca Mountain nuclear waste repository in Nevada; defending challenges to the United States’ implementation of international treaties involving the elimination of chemical weapons; and prosecuting civil enforcement actions under the Clean Water Act that have protected hundreds of thousands of wetland acres and recovered millions of dollars in penalties.

Environmental Enforcement Section

Thomas A. Mariani, Section Chief

The Environmental Enforcement Section is one of the largest litigating sections in the Department and includes nearly one-half of the Division’s lawyers. The Section is responsible for bringing civil judicial actions under most federal laws enacted to protect public health and the environment from the adverse effects of pollution, such as the Clean Air Act, Clean Water Act, Safe Drinking Water Act, Oil Pollution Act, RCRA and the Superfund law (CERCLA). The breadth of the Section’s practice is extensive and challenging. It includes cases of national scope, such as cases against multiple members of an identified industry, to obtain broad compliance with the environmental laws. Through its enforcement of the Superfund law, the Section seeks to compel responsible parties either to clean up hazardous waste sites or to reimburse the United States for the cost of cleanup, thereby ensuring that they, and not the public, bear the burden of paying for cleanup. The Superfund law is also a basis of the Section’s actions to recover damages for injury to natural resources that are under the trusteeship of federal agencies.

Executive Office

Andrew T. Collier, Executive Officer

The Executive Office is the operational management and administrative support section for ENRD. It provides financial management, human resources, information technology, procurement, facilities, security, litigation support, and other important services to the Division’s workforce. The Executive Office takes advantage of cutting-edge technology to provide sophisticated automation facilities to ENRD employees. By utilizing new technologies and innovative business processes — and by in-sourcing services traditionally provided by contractors and equipping employees to better serve themselves — the Executive Office is able to achieve significant cost savings for the American public on an annual basis.

Indian Resources Section

S. Craig Alexander, Section Chief

The Indian Resources Section represents the United States in its trust capacity for Indian Tribes and their members. These suits include establishing water rights, establishing and protecting hunting and fishing rights, collecting damages for trespass on Indian lands, and establishing reservation boundaries and rights to land. The Indian Resources Section also devotes approximately half of its efforts toward defending federal statutes, programs, and decisions intended to benefit Indians and Tribes. The litigation is of vital interest to the Indians and helps to fulfill an important responsibility of the federal government.

Land Acquisition Section

Andrew M. Goldfrank, Section Chief

The Land Acquisition Section is responsible for acquiring land through condemnation proceedings, for use by the Federal Government for purposes ranging from establishing public parks to creating missile sites. The Land Acquisition Section is also responsible for reviewing and approving title to lands acquired by direct purchase for the same purposes. The legal and factual issues involved are often complex and can include the power of the United States to condemn under specific acts of Congress, ascertainment of the market value of property, applicability of zoning regulations, and problems related to subdivisions, capitalization of income, and the admissibility of evidence.

Law and Policy Section

Justin Smith, Section Chief

The Law and Policy Section staff advises and assists the Assistant Attorney General on environmental legal and policy questions, particularly those that affect multiple sections in the Division. Working with the Office of Legislative Affairs, it coordinates the Division’s response to legislative proposals and Congressional requests, prepares for appearances of Division witnesses before Congressional committees, and drafts legislative proposals in connection with the Division’s work. Other duties include responding to congressional and citizen correspondence and FOIA requests, as well as serving as the Division’s ethics officer and counselor, alternative dispute resolution counselor, and liaison with State and local governments. Attorneys in the Section coordinate the Division’s amicus practice, handling many of these cases directly or together with Appellate, undertake other special litigation projects, and coordinate the Division’s involvement in international legal matters.

Natural Resources Section

James Gette, Section Chief

The Natural Resources Section is responsible for a diverse and extensive docket of primarily defensive litigation involving more than eighty statutes, treaties and the U.S. Constitution. The Section’s responsibilities include cases in virtually every U.S. district court of the Nation, its territories and possessions, the U.S. Court of Federal Claims, and State courts. The subject matter involves federal land, resource and ecosystem management decisions challenged under a wide variety of federal environmental statutes and affecting more than a half-billion acres of lands managed by the Departments of the Interior and Agriculture (totaling nearly one-quarter of the entire land mass of the United States) and an additional 300 million acres of subsurface mineral interests; vital national security programs involving military preparedness and border protection, nuclear materials management, and weapons system research; billions of dollars in constitutional claims of Fifth Amendment takings covering a broad spectrum of Federal activities affecting private property; challenges brought by individual Native Americans and Indian Tribes relating to the United States’ trust responsibility; a panoply of cultural resource matters including cases related to historic buildings, repatriation of ancient human remains and salvage of shipwrecks; preserving federal water rights and prosecuting water rights adjudications; ensuring proper mineral royalty payments to the Treasury; and litigation involving offshore boundary disputes, interstate water compacts and other issues in Supreme Court original actions in coordination with the Office of the Solicitor General. The Section’s clients include virtually every major Federal executive branch agency.

Office of Environmental Justice

Cynthia M. Ferguson, Director

The Office of Environmental Justice (OEJ) engages all Justice Department bureaus, components, and offices in the collective pursuit of environmental justice. The mission of OEJ is to protect overburdened and underserved communities from the harm caused by environmental crimes, pollution, and climate change. The Office: serves as the central hub to implement the Department of Justice’s Comprehensive Environmental Justice Enforcement Strategy; builds partnerships with community advocates; and promotes fair and equal treatment and meaningful involvement of all people in environmental decision-making process. OEJ was established within the Environment and Natural Resources Division on May 5, 2022.

Wildlife and Marine Resources Section

S. Jay Govindan, Section Chief

WMRS litigates complex civil cases in federal courts across the country brought under the federal wildlife and marine resource statutes, including the Endangered Species Act, the Magnuson-Stevens Fishery Conservation and Management Act, the Migratory Bird Treaty Act, and the Marine Mammal Protection Act. The Section also has responsibility for civil enforcement of the Animal Welfare Act (AWA) and for civil forfeitures under the Animal Fighting Venture Prohibition Act (AFVPA). WMRS primarily handles civil defensive litigation involving challenges to rulemaking and other decisions by federal agencies charged with implementing the various wildlife statutes and to decisions or actions of federal agencies taken to comply with such statutes. Civil litigation, particularly under the Endangered Species Act, often pits the needs of protected species against pressures for development by both the Federal Government and private enterprise.
