The National Environmental Policy Act (NEPA) is a United States environmental law that promotes the enhancement of the environment and established the President's Council on Environmental Quality (CEQ).
 The law was enacted on January 1, 1970.
 NEPA's importance can not be overstated.
 Eccleston has called it the world's equivalent of an “environmental Magna Carta”.
 To date, more than 100 nations around the world have enacted national environmental policies modeled after NEPA.
The Oregon Department of Energy (ODOE) is the chief regulatory agency of the government of the U.S. state of Oregon responsible for matters related to energy production, conservation and related safety and environmental impact.
 The Oregon Department of Energy (ODOE) is responsible for over 40 programs.
 The mission of the department is: "Leading Oregon to a safe, clean, and sustainable energy future."
The Oklahoma Department of Environmental Quality (DEQ) is a department of the government of Oklahoma under the Governor of Oklahoma.
 It is responsible for protecting human health and for safeguarding the natural environment: air, water, and land.
 DEQ is chiefly responsible for the environmental policy of Oklahoma.
 It is governed by a thirteen member Environmental Quality Board appointed by the Governor, which in turn appoints an Executive Director to administer the Department.
The Resource Conservation and Recovery Act (RCRA), enacted in 1976, is the principal federal law in the United States governing the disposal of solid waste and hazardous waste.
The Illinois Environmental Protection Agency (Illinois EPA) of the state of Illinois is the primary body concerned with the protection of the environment for the state.
 The Illinois EPA's mission is "to safeguard environmental quality, consistent with the social and economic needs of the State, so as to protect health, welfare, property and the quality of life."
The Oregon Department of Environmental Quality (DEQ) is the chief regulatory agency of the government of the U.S. state of Oregon responsible for protecting and enhancing the state's natural resources and managing sanitary and toxic waste disposal.
 The agency employs approximately 700 scientists, engineers, technicians, administrators, and environmental specialists.
 It has headquarters in Portland, regional administrative offices in Bend, Eugene, and Portland; and field offices in Coos Bay, Grants Pass, Hermiston, Medford, Pendleton, Roseburg, Salem, and The Dalles.
 The Laboratory and Environmental Assessment Division operates an environmental laboratory in Hillsboro.
 The agency's director has the authority to impose fines for violations of the state's anti-pollution laws.
 In addition to its state mandate, the United States Environmental Protection Agency (EPA) has delegated authority to DEQ to administer federal environmental programs including the federal Clean Air Act, Clean Water Act, and Resource Conservation and Recovery Act within the state.
The Indoor Environmental Quality Global Alliance (IEQ-GA) was initiated in 2014 aiming to improve the actual, delivered indoor environmental quality in buildings through coordination, education, outreach and advocacy.
 The alliance works to supply information, guidelines and knowledge on the indoor environmental quality (IEQ) in buildings and workplaces, and to provide occupants in buildings and workplaces with an acceptable indoor environmental quality ((indoor air quality (IAQ), thermal conditions, visual quality, and acoustical quality)) and help promote implementation in practice of knowledge from research on the field.
Alkali Lake Chemical Waste Dump is a hazardous waste disposal site near the southwest edge of Alkali Lake, a seasonally dry playa in Lake County, Oregon.
 It is in the Summer Lake watershed.
 The site has been the focus of Oregon Department of Environmental Quality (DEQ) efforts to remediate a complex mix of toxic chemicals.
 Problems were initially caused by the dumping of hazardous waste near the lakebed between 1969 and 1971.
The Oregon PHL/DEQ Laboratories are the Oregon Department of Environmental Quality (DEQ) and Oregon Department of Human Services (DHS) laboratories located in a single building in Hillsboro, Oregon, United States.
 DHS operates the Oregon State Public Health Laboratory (OSPHL), and the DEQ operates their Laboratory and Environmental Assessment Division at the site.
 The laboratories previously were located at Portland State University, moving to the new location near Cornelius Pass Road and the Sunset Highway (U.S. Route 26) in northeast Hillsboro in 2007.
The Environmental Quality Improvement Act of 1970 is a United States environmental law which was passed to work in conjunction with the National Environmental Policy Act of 1969 (NEPA).
 One of the two major purposes of the Act was to authorize the creation of an Office of Environmental Quality to provide the professional and administrative staff needed for the Council on Environmental Quality.
 The second major purpose was to "assure that each Federal department and agency conducting or supporting public works activities which affect the environment shall implement the policies under existing law".
 To accomplish these purposes, the act gave more responsibilities to the Chairman of the Council on Environmental Quality in his new role as Director of the Office of Environmental Quality.
