88-757: Established as the Wheeler Peak Wild Area in 1960, 6,051 acres (2,449 ha) the area was re-designated the Wheeler Peak Wilderness in 1964 with the passage of the Wilderness Act . The area was expanded by 14,700 acres (5,900 ha) in 1980 with the passage of the New Mexico Wilderness Act. In 1996, public law 104-333 transferred 764 acres (309 ha) from the wilderness south of the ridge between Simpson Peak and Old Mike Peak and west of Blue Lake to

176-412: A "nonroad" engine program ( 42 U.S.C.   § 7547 ), which expanded EPA regulation to locomotives, heavy equipment and small equipment engines fueled by diesel (compression-ignition), and gas and other fuels (spark-ignition), and marine transport. EPA has developed a variety of voluntary programs to incentivize and promote reduction in transportation-related air pollution, including elements of

264-621: A conference committee to resolve differences between the House and Senate versions of the bill, the Act eventually was eventually signed into law by President Johnson on September 3, 1964. The Wilderness Act of 1964 was significant in American environmental legislation, setting a start for the federal protection of wilderness areas across the United States. It was passed with the support in both

352-520: A criteria pollutant, controlling it through mobile source authorities, but it was required to do so after successful litigation by Natural Resources Defense Council (NRDC) in 1976 (43 FR 46258 ). The 1977 CAA Amendments created a process for regular review of the NAAQS list, and created a permanent independent scientific review committee to provide technical input on the NAAQS to EPA. EPA added regulations for PM2.5 in 1997 (62 FR 38652 ), and updates

440-652: A critical moment in the history of environmental protection but also set the stage for ongoing debates about the role of government in managing natural resources and the balance between conservation and development. The 1964 Wilderness Act, which was praised for protecting undisturbed American landscapes, encountered strong resistance from the Sagebrush Rebellion in the latter part of the 1970s. The majority of "resource Westerners" who were affected by federal environmental regulations that limited their access to public lands, such as ranchers, miners, and loggers, were

528-1095: A foundation that allows for many new additions of American land to be designated as wilderness. Congress considers additional proposals every year, some recommended by federal agencies and many proposed by grassroots conservation and sportsmen's organizations. Additional laws adding areas to the NWPS include: Congressional bills are pending to designate new wilderness areas in Utah, Colorado, Washington, California, Virginia, Idaho, West Virginia, Montana and New Hampshire. Grassroots coalitions are working with local congressional delegations on legislative proposals for additional wilderness areas, including Vermont, southern Arizona, national grasslands in South Dakota, Rocky Mountain peaks of Montana, Colorado and Wyoming. The U.S. Forest Service has recommended new wilderness designations, which citizen groups may propose to expand. In 2014, America celebrated "50 Years of Wilderness" and Wilderness50 which

616-752: A new section to authorize abatement of international air pollution. The Air Quality Act of 1967 ( Pub. L.   90–148 ) authorized planning grants to state air pollution control agencies, permitted the creation of interstate air pollution control agencies, and required HEW to define air quality regions and develop technical documentation that would allow states to set ambient air quality and pollution control technology standards, and required states to submit implementation plans for improvement of air quality, and permitted HEW to take direct abatement action in air pollution emergencies. It also authorized expanded studies of air pollutant emission inventories, ambient monitoring techniques, and control techniques. This enabled

704-526: A new title to address the issue of acid rain, and particularly nitrogen oxides (NO x ) and sulfur dioxide (SO 2 ) emissions from electric power plants powered by fossil fuels, and other industrial sources. The Acid Rain Program was the first emissions trading program in the United States, setting a cap on total emissions that was reduced over time by way of traded emissions credits, rather than direct controls on emissions. The program evolved in two stages:

792-532: A period known as a baby boom . Additionally, American transportation systems grew in size which made transportation easier and increased environmental concerns. A leading concern was that environmental degradation would have an impact on air and water quality, this was partly addressed by the initial passage of the Clean Air Act in 1963. The problem of American wilderness still persisted even after attempts to regulate pollutants. Part of America's identity

880-572: A series of laws to reduce air pollution, and Congress began discussing whether to take further action in response. At the time, the primary federal agencies interested in air pollution were the United States Bureau of Mines , which was interested in "smoke abatement" (reducing smoke from coal burning), and the United States Public Health Service , which handled industrial hygiene and was concerned with

968-553: A solely national program, the CAA imposes responsibilities on the U.S. states to create plans to implement the Act's requirements. EPA then reviews, amends, and approves those plans. EPA first promulgated SIP regulations in 1971 and 1972. The 1970 Amendments imposed eight criteria that an implementation plan must meet. The EPA is required to approve plans that adhere to the Senate's three-year mandate for primary air quality standards even if

1056-471: A span of four days. One month later, the Senate also introduced a draft bill of the Wilderness Act. President John F. Kennedy , was a supporter of the Wilderness Act, his administration worked to rally Legislators to pass the bill. During the 87th Congressional session , the Senate voted and passed a version of the Wilderness Act, however it never made it to a vote in the House and its overall fate

1144-546: A very specific boundary line in statutory law. Once a wilderness area has been added to the system, its protection and boundary can be altered only by Congress. The basics of the NWPS set out in the Wilderness Act are straightforward: Section 4 lists what usage is not allowed on land protected by the NWPS, and define the exceptions to the rules. Prohibited actions include: Sections 5, 6, and 7 discuss how Congress shall handle acquisition of more land, gifts, and addition of new designated wilderness areas. Some topics surrounding

1232-426: Is a stub . You can help Misplaced Pages by expanding it . Wilderness Act The Wilderness Act of 1964 ( Pub. L.   88–577 ) is a federal land management statute meant to protect federal wilderness and to create a formal mechanism for designating wilderness. It was written by Howard Zahniser of The Wilderness Society . After over sixty drafts and eight years of work, President Lyndon B. Johnson signed

1320-592: Is a growing coalition of federal agencies, non-profit organizations, academic institutions, and other wilderness user groups has been created to document this historical commemoration honoring America's "True American Legacy of Wilderness". A series of projects and events were held to commemorate the 50th year of the Wilderness Act, including community museum, airport and visitor center displays; National website and social media campaign; Smithsonian photography exhibition; Washington D.C. Wilderness Week in September, and

1408-481: Is counted, the Clean Air Act has substantially reduced air pollution and improved US air quality—benefits which EPA credits with saving trillions of dollars and many thousands of lives each year. In the United States, the "Clean Air Act" typically refers to the codified statute at 42 U.S.C. ch. 85 . That statute is the product of multiple acts of Congress , one of which—the 1963 act—was actually titled

1496-489: Is one of the United States' first and most influential modern environmental laws . As with many other major U.S. federal environmental statutes , the Clean Air Act is administered by the U.S. Environmental Protection Agency (EPA), in coordination with state, local, and tribal governments. EPA develops extensive administrative regulations to carry out the law's mandates. Associated regulatory programs, which are often technical and complex, implement these regulations. Among

1584-563: The Library of Congress . The report was completed a year later, and the results released the data that had been requested which provided more information on the current state of federal land. In 1956, about seven years later, the first committee hearings began in House and Senate on the topic of protecting Wildlife Refuge areas. The first drafts of the Wilderness Act were introduced in the House in January 1957, where 6 bills were introduced over

1672-530: The National Wilderness Conference . The Wilderness Act of 1964 is a pivotal legislation governing the preservation and management of wilderness areas in the United States. It provides a framework for Congress to designate federally managed lands as wilderness areas and mandates federal land agencies to manage these areas in a manner consistent with their natural wilderness character. Celebrating its fiftieth anniversary in September 2014,

1760-599: The United States of America previously protected by administrative orders. The current amount of areas designated by the NWPS as wilderness totals 757 areas encompassing 109.5 million acres of federally owned land in 44 states and Puerto Rico (5% of the land in the United States). Throughout the 1950s and 1960s, there were growing concerns about the rapidly growing population in America after World War II ,

1848-416: The de facto standard that automobile manufacturers subsequently accepted, to avoid having to develop different emission systems in their vehicles for different states. However, in September 2019, President Donald Trump attempted to revoke this waiver, arguing that the stricter emissions have made cars too expensive, and by removing them, will make vehicles safer. EPA's Andrew Wheeler also stated that while

1936-927: The ozone layer . Consistent with the US commitments in the Montreal Protocol , CAA Title VI, added by the 1990 CAA Amendments, mandated regulations regarding the use and production of chemicals that harm Earth's stratospheric ozone layer. Under Title VI, EPA runs programs to phase out ozone-destroying substances, track their import and export, determine exemptions for their continued use, and define practices for destroying them, maintaining and servicing equipment that uses them, identifying new alternatives to those still in use , and licensing technicians to use such chemicals. Rules for pollutants emitted from internal combustion engines in vehicles. Since 1965, Congress has mandated increasingly stringent controls on vehicle engine technology and reductions in tailpipe emissions. Today,

2024-509: The 50th anniversary in 2014, it encompassed over 109 million acres across 758 areas in 44 states. This expansion has been largely due to the bipartisan support wilderness designations often receive, reflecting a shared value across the political spectrum. Clean Air Act (United States) The Clean Air Act ( CAA ) is the United States' primary federal air quality law , intended to reduce and control air pollution nationwide . Initially enacted in 1963 and amended many times since, it

2112-416: The Act has facilitated the protection of over 109 million acres of public land. The commemorative symposium, "The Wilderness Act at 50," organized by Lewis & Clark Law School, brought together experts to discuss various facets of the Act's evolution and impact. Notably, discussions delved into the role of litigation in shaping wilderness management, emphasizing strategic decisions by plaintiffs. Moreover,

2200-752: The Act remained unanswered, which has prompted future actions and controversies. When the Wilderness Act was passed, it ignored lands managed by the Bureau of Land Management because of uncertainty of policy makers surrounding the future of those areas. The uncertainty was clarified in 1976 with the passing of the Federal Land Policy and Management Act , which stated that land managed by the Bureau of Land Management would remain federally owned and, between March 1978 and November 1980, would be reviewed to possibly be classified as wilderness. Some argue that

2288-454: The Act. The EPA's auto emission standards for greenhouse gas emissions issued in 2010 and 2012 are intended to cut emissions from targeted vehicles by half, double fuel economy of passenger cars and light-duty trucks by 2025 and save over $ 4 billion barrels of oil and $ 1.7 trillion for consumers. The agency has also proposed a two-phase program to reduce greenhouse gas emissions for medium and heavy duty trucks and buses. In addition, EPA oversees

2376-618: The Agency feels the plan does not appear feasible. In Union Electric Co. v. Environmental Protection Agency the Supreme Court considered whether the Agency was required to reject plans that were not technologically or economically feasible. The court decided that states could adopt emission standards stricter than national standards and "force" technology (i.e. require installation of more advanced technologies). The 1977 CAA Amendments added SIP requirements for areas that had not attained

2464-415: The Clean Air Act's major regulatory programs. Today, the following are major regulatory programs under the Clean Air Act. The National Ambient Air Quality Standards (NAAQS) govern how much ground-level ozone (O 3 ), carbon monoxide (CO), particulate matter (PM 10 , PM 2.5 ), lead (Pb), sulfur dioxide (SO 2 ), and nitrogen dioxide (NO 2 ) are allowed in the outdoor air. The NAAQS set

2552-460: The Clean Air Act, and another of which—the 1970 act—is most often referred to as such. In the U.S. Code, the statute itself is divided into subchapters, and the section numbers are not clearly related to the subchapters. However, in the bills that created the law, the major divisions are called "Titles", and the law's sections are numbered according to the title (e.g., Title II begins with Section 201). In practice, EPA, courts, and attorneys often use

2640-502: The Clean Diesel Campaign, Ports Initiative, SmartWay program (for the freight transportation sector), and others. The federal government has regulated the chemical composition of transportation fuels since 1967, with significant new authority added in 1970 to protect public health. One of EPA's earliest actions was the elimination of lead in U.S. gasoline beginning in 1971, a project that has been described as "one of

2728-529: The EPA test results with real-world driving. In 1996, EPA proposed updating the Federal Testing Procedures to add a new higher-speed test (US06) and an air-conditioner-on test (SC03) to further improve the correlation of fuel economy and emission estimates with real-world reports. In December 2006 the updated testing methodology was finalized to be implemented in model year 2008 vehicles and set

2816-527: The EPA with enforcement authority and requiring states to develop State Implementation Plans for how they would meet new national ambient air quality standards by 1977. This cooperative federal model continues today. The law recognizes that states should lead in carrying out the Clean Air Act, because pollution control problems often require special understanding of local conditions such as geography, industrial activity, transportation and housing patterns. However, states are not allowed to have weaker controls than

2904-484: The EPA, as well as giving the EPA the ability to regulate the inclusion of renewable sources, notably, through a $ 27 billion green bank , among other methods. Other important but less foundational Clean Air Act regulatory programs tend to build on or cut across the above programs: The 1963 act required development of State Implementation Plans (SIPs) as part of a cooperative federalist program for developing pollution control standards and programs. Rather than create

2992-473: The Interior, emerged as a key player in this situation. During his tenure, he worked to extend the scope of mineral rights to include coal and oil, a goal that suited the interests of people impacted by the Wilderness Act and other environmental laws. Watt aimed to reduce federal constraints and give local governments more authority over land management choices. These efforts were perceived as a direct answer to

3080-450: The NAAQS from time to time based on emerging environmental and health science. The National Emissions Standards for Hazardous Air Pollutants (NESHAPs) govern how much of 187 toxic air pollutants are allowed to be emitted from industrial facilities and other sources. Under the CAA, hazardous air pollutants (HAPs, or air toxics) are air pollutants other than those for which NAAQS exist, which threaten human health and welfare. The NESHAPs are

3168-473: The Prevention of Significant Deterioration (PSD) of air quality in areas attaining the NAAQS. The 1977 CAAA also contained requirements pertaining to sources in non-attainment areas for NAAQS. A non-attainment area is a geographic area that does not meet one or more of the federal air quality standards. Both of these 1977 CAAA established major permit review requirements to ensure attainment and maintenance of

3256-554: The SIP requirements by adding "Prevention of Significant Deterioration" (PSD) requirements. These requirements protect areas, including particularly wilderness areas and national parks, that already met the NAAQS. The PSD provision requires SIPs to preserve good quality air in addition to cleaning up bad air. The new law also required New Source Review (investigations of proposed construction of new polluting facilities) to examine whether PSD requirements would be met. The Clean Air Act provided

3344-581: The Senate (73–12) and the House of Representatives (373–1), showing bipartisan agreement on the importance of preserving natural landscapes for future generations. This act established the National Wilderness Preservation System, defining wilderness as areas, according to Wilderness Society president Howard Zahniser, "where the earth and its community of life are untrammeled by man." It also stopped most forms of development and motorized vehicles in these areas. The success of

3432-657: The Wilderness Act and the growing federal oversight of environmental protection, opposition movements like the Sagebrush rebellion and the Wise use movement emerged, particularly in the American West. These movements represented a shift in the political landscape, fighting against what they saw as federal overreach and advocating for states' rights and individual property rights over public land management. The conflict over wilderness protection and public land management showed

3520-537: The Wilderness Act had a lot to do with the groups who supported it. These groups included not only environmental organizations like the Wilderness Society and the Sierra Club but also labor and civic groups, showing great public interest in preserving America's wilderness. The Wilderness Act of 1964 included a few provisions (sections), that covered different aspects its implementation. Section 2 of

3608-406: The Wilderness Act into law on September 3, 1964, creating the legal definition of wilderness in the United States and protecting 9.1 million acres (37,000 km²) of federal land. The Wilderness Act is well known for its succinct and poetic definition of wilderness: "A wilderness, in contrast with those areas where man and his own works dominate the landscape, is hereby recognized as an area where

3696-426: The Wilderness Act provides a justification for and definition of what constitutes an area of land as wilderness. Wilderness Act land is chosen from existing federal land and by determining which areas are considered to meet the following criteria: Section 3 of the Act outlines the creation and regulation of the National Wilderness Preservation System (NWPS). When Congress designates each wilderness area, it includes

3784-853: The acceptable levels of certain air pollutants in the ambient air in the United States. Prior to 1965, there was no national program for developing ambient air quality standards, and prior to 1970 the federal government did not have primary responsibility for developing them. The 1970 CAA amendments required EPA to determine which air pollutants posed the greatest threat to public health and welfare and promulgate NAAQS and air quality criteria for them. The health-based standards were called "primary" NAAQS, while standards set to protect public welfare other than health (e.g., agricultural values) were called "secondary" NAAQS. In 1971, EPA promulgated regulations for sulfur oxides, particulate matter, carbon monoxide, photochemical oxidants, hydrocarbons, and nitrogen dioxide (36 FR 22384 ). Initially, EPA did not list lead as

3872-416: The administrating agencies to ban bicycles from wilderness areas based on the statutory text prohibiting "other mechanical forms of transport". It is noteworthy that mountain bikes did not exist when the Wilderness Act was enacted, hence they were not explicitly identified in the statute. The prohibition on bicycles has led to opposition from mountain bikers to the opening of new wilderness areas. Because of

3960-610: The administration's decision. In March 2022 the Biden administration reversed the Trump-era rule, allowing California to again set stricter auto emissions standards. Between the Second Industrial Revolution and the 1960s, the United States experienced increasingly severe air pollution . Following the 1948 Donora smog event, the public began to discuss air pollution as a major problem, states began to pass

4048-537: The agency respects federalism, it could not allow one state to dictate standards for the entire nation. California's governor Gavin Newsom considered the move part of Trump's "political vendetta" against California and stated his intent to sue the federal government. Twenty-three states, along with the District of Columbia and the cities of New York City and Los Angeles, joined California in a federal lawsuit challenging

4136-425: The air, measure their quantity, and have a plan to control and minimize them as well as to periodically report. This consolidated requirements for a facility into a single document. In non-attainment areas, permits were required for sources that emit as little as 50, 25, or 10 tons per year of VOCs depending on the severity of the region's non-attainment status. Most permits are issued by state and local agencies. If

4224-436: The applicable NAAQS ("nonattainment areas"). In these areas, states were required to adopt plans that made "reasonable further progress" toward attainment until all "reasonably available control measures" could be adopted. As progress on attainment was much slower than Congress originally instructed, major amendments to SIP requirements in nonattainment areas were part of the 1990 CAA Amendments. The 1977 CAA Amendments modified

4312-694: The area in 1993. Other local avian fauna include many common rocky mountain species such magpies , Canada jays , chickadees and woodpeckers . Many rivers and alpine lakes within the Wheeler Peak wilderness are stocked with cutthroat and/or rainbow trout every few years by the New Mexico Department of Game and Fish . Flora of the Wheeler Peak Wilderness vary by altitude, and include cottonwoods , Bristlecone pines , Engelmann spruce and sub-alpine fir and many species of wildflower . This New Mexico state location article

4400-408: The causes of lung health problems. After several years of proposals and hearings, Congress passed the first federal legislation to address air pollution in 1955. The Air Pollution Control Act of 1955 authorized a research and training program, sending $ 3 million per year to the U.S. Public Health Service for five years, but did not directly regulate pollution sources. The 1955 Act's research program

4488-482: The criteria to determine wilderness are vague and open to interpretation. For example, one criterion for wilderness is that it be roadless, and the act does not define the term roadless. Wilderness advocacy groups and some agency staff have attempted to use this standard: "the word 'roadless' refers to the absence of roads that have been improved and maintained by mechanical means." For more information, see Revised Statute 2477 . The Wilderness Act has been interpreted by

4576-540: The demands of the Sagebrush Rebellion. Due to regulatory rollbacks which were perceived as a decrease in federal government control over Western lands, the Sagebrush Rebellion temporarily felt victorious due to its alliance with the Reagan administration. The pioneering research and advocacy work of Margaret and Olaus Murie and Celia Hunter, along with the Alaska Conservation Society, was crucial to

4664-536: The earth and its community of life are untrammeled by man, where man himself is a visitor who does not remain." – Howard Zahniser When Congress passed and President Lyndon B. Johnson signed the Wilderness Act on September 3, 1964, it created the National Wilderness Preservation System . The initial statutory wilderness areas, designated in the Act, comprised 9.1 million acres (37,000 km²) of national forest wilderness areas in

4752-472: The equipment required to be installed in new and modified industrial facilities, and the rules for determining whether a facility is "new". The 1970 CAA required EPA to develop standards for newly constructed and modified stationary sources (industrial facilities) using the "best system of emission reduction which (taking into account the cost of achieving such reduction) the [EPA] determines has been adequately demonstrated." EPA issued its first NSPS regulation

4840-761: The federal funding and legislation of the 1960s. In the Clean Air Amendments of 1970 ( Pub. L.   91–604 ), Congress greatly expanded the federal mandate by requiring comprehensive federal and state regulations for both industrial and mobile sources. The law established the National Ambient Air Quality Standards (NAAQS), New Source Performance Standards (NSPS); and National Emissions Standards for Hazardous Air Pollutants (NESHAPs), and significantly strengthened federal enforcement authority, all toward achieving aggressive air pollution reduction goals. To implement

4928-476: The federal government to increase its activities to investigate enforcing interstate air pollution transport, and, for the first time, to perform far-reaching ambient monitoring studies and stationary source inspections. The 1967 act also authorized expanded studies of air pollutant emission inventories, ambient monitoring techniques, and control techniques. While only six states had air pollution programs in 1960, all 50 states had air pollution programs by 1970 due to

5016-418: The federal standards, but carves out a special exemption for California due to its past issues with smog pollution in the metropolitan areas. In practice, when California 's environmental agencies decide on new vehicle emission standards, they are submitted to the EPA for approval under this waiver, with the most recent approval in 2009. The California standard was adopted by twelve other states, and established

5104-495: The first draft of the Wilderness Act. The Wilderness Act of 1964 went through numerous discussions and drafts before finally being enacted during the 88th Congress. The concept of developing a Federal Wilderness system through Congress began to be seriously explored in 1948 when a group of Congressional members requested a report be compiled on the topic through the Legislative Reference Service within

5192-414: The first stage required more than 100 electric generating facilities larger than 100 megawatts to meet a 3.5 million ton SO 2 emission reduction by January 1995. The second stage gave facilities larger than 75 megawatts a January 2000 deadline. The program has achieved all of its statutory goals. The CAA ozone program is a technology transition program intended to phase out the use of chemicals that harm

5280-413: The great public health achievements of the 20th century." EPA continues to regulate the chemical composition of gasoline , avgas , and diesel fuel in the United States. The 1990 amendments authorized a national operating permit program, sometimes called the "Title V Program", covering thousands of large industrial and commercial sources. It required large businesses to address pollutants released into

5368-555: The growing division in American environmental politics, showing bigger cultural and ideological divides. This period of environmental opposition not only challenged the principles of federal land management but also contributed to the reorganization of political ideas, playing a role in the evolution of the New Right and the Republican Party's stance on environmental regulations. The Wilderness Act, therefore, not only marked

SECTION 60

5456-496: The land preserved for future generations. The shortcomings of previous protections were exclaimed by efforts to develop protected lands for mining and energy utilization, a prominent example is the Echo Park Dam controversy at Dinosaur National Monument .The encroachment on existing protected land motivated conservationists to lobby Congress to add additional protections to wilderness land, in particular, Howard Zahniser wrote

5544-611: The largest Clean Air Act settlements have been reached with automakers accused of circumventing the Act's vehicle and fuel standards (e.g., the 2015 " Dieselgate " scandal). Much of EPA's regulation of greenhouse gas (GHG) emissions occurs under the programs discussed above. EPA began regulating GHG emissions following the 2007 Supreme Court ruling in Massachusetts v. EPA , the EPA's subsequent endangerment finding, and development of specific regulations for various sources. The EPA's authority to regulate carbon dioxide emissions

5632-630: The latter numbering scheme. Although many parts of the statute are quite detailed, others set out only the general outlines of the law's regulatory programs, and leave many key terms undefined. Responsible agencies, primarily EPA, have therefore developed administrative regulations to carry out Congress's instructions. EPA's proposed and final regulations are published in the Federal Register , often with lengthy background histories. The existing CAA regulations are codified at 40 C.F.R. Subchapter C, Parts 50–98. These Parts more often correspond to

5720-896: The law requires EPA to establish and regularly update regulations for pollutants that may threaten public health, from a wide variety of classes of motor vehicles, that incorporate technology to achieve the "greatest degree of emission reduction achievable", factoring in availability, cost, energy, and safety ( 42 U.S.C.   § 7521 ). EPA sets standards for exhaust gases, evaporative emissions, air toxics, refueling vapor recovery, and vehicle inspection and maintenance for several classes of vehicles that travel on roadways. EPA's "light-duty vehicles" regulations cover passenger cars, minivans, passenger vans, pickup trucks, and SUVs. "Heavy-duty vehicles" regulations cover large trucks and buses. EPA first issued motorcycle emissions regulations in 1977 (42 FR 1122 ) and updated them in 2004 (69 FR 2397 ). The air pollution testing system for motor vehicles

5808-460: The lifetimes of pre-existing facilities. In the 1977 CAA Amendments, Congress required EPA to conduct a "new source review" process ( 40 CFR 52 , subpart I) to determine whether maintenance and other activities rises to the level of modification requiring application of NSPS. The Acid Rain Program (ARP) is an emissions trading program for power plants to control the pollutants that cause acid rain . The 1990 CAA Amendments created

5896-866: The most important, the National Ambient Air Quality Standards program sets standards for concentrations of certain pollutants in outdoor air, and the National Emissions Standards for Hazardous Air Pollutants program which sets standards for emissions of particular hazardous pollutants from specific sources. Other programs create requirements for vehicle fuels, industrial facilities, and other technologies and activities that impact air quality. Newer programs tackle specific problems, including acid rain, ozone layer protection, and climate change. The CAA has been challenged in court many times, both by environmental groups seeking more stringent enforcement and by states and utilities seeking greater leeway in regulation. Although its exact benefits depend on what

5984-601: The national greenhouse gas inventory reporting program. Following the Supreme Court decision in West Virginia v. EPA , which ruled that Congress did not grant EPA the authority to require "outside the fence" options for limiting carbon dioxide at power plants, the Inflation Reduction Act of 2022 specifically defined carbon dioxide, hydrofluorocarbons, methane, nitrous oxide, perfluorocarbons, and sulfur hexafluoride as greenhouse gases to be regulated by

6072-553: The national minimum criteria set by EPA. EPA must approve each SIP, and if a SIP is not acceptable, EPA can retain CAA enforcement in that state. For example, California was unable to meet the new standards set by the 1970 amendments, which led to a lawsuit and a federal state implementation plan for the state. The federal government also assists the states by providing scientific research, expert studies, engineering designs, and money to support clean air programs. The law also prevents states from setting standards that are more strict than

6160-416: The nearby Taos Pueblo . The Wheeler Peak Wilderness is home to a variety of birds and mammals. Marmots , pikas , bighorn sheep , and golden eagles are year-round residents. Rocky Mountain elk , mule deer dwell in the area during the summer season, feeding on grasses and new aspen growth in the higher elevations. Although bighorn sheep are native to the area, the local population was re-introduced to

6248-403: The newly created EPA immediately before major amendments in 1970. EPA has administered the Clean Air Act ever since, and Congress added major regulatory programs in 1977 and 1990. Most recently, the U.S. Supreme Court's ruling in Massachusetts v. EPA resulted in an expansion of EPA's CAA regulatory activities to cover greenhouse gases . The Clean Air Act of 1963 ( Pub. L.   88–206 )

6336-407: The next year, covering steam generators, incinerators, Portland cement plants, and nitric and sulfuric acid plants (36 FR 24876 ). Since then, EPA has issued dozens of NSPS regulations, primarily by source category. The requirements promote industrywide adoption of available pollution control technologies. However, because these standards apply only to new and modified sources, they promote extending

6424-535: The ones who initiated this backlash. The Federal Land Policy Management Act (FLPMA) of 1976, which changed the Bureau of Land Management's emphasis from resource extraction to conservation, was a major source of dispute because it significantly restricted these groups' ability to make a living. Many in the West were unhappy as a result of this alleged government overreach and saw it as "federal colonialism." James G. Watt, nominated by President Ronald Reagan as Secretary of

6512-635: The passage of the Wilderness Act, and to the creation of the Arctic National Wildlife Refuge. Margaret Murie testified passionately before Congress in favor of the Wilderness Act. Margaret worked with Wilderness Society staffer Howard Zahniser , author of the bill, to promote passage of the act, and she attended the signing ceremony. As of 2014, the National Wilderness Preservation System comprised over 109 million acres (441,000 km²), involving federal lands administered by four agencies: The Wilderness Act has created

6600-439: The precedent of a 12-year review cycle for the test procedures. In February 2005, EPA launched a program called "Your MPG" that allows drivers to add real-world fuel economy statistics into a database on EPA's fuel economy website and compare them with others and with the original EPA test results. EPA conducts fuel economy tests on very few vehicles. Two-thirds of the vehicles the EPA tests themselves are randomly selected and

6688-837: The remaining third is tested for specific reasons. Although originally created as a reference point for fossil-fueled vehicles, driving cycles have been used for estimating how many miles an electric vehicle will get on a single charge. The 1970 CAA amendments provided for regulation of aircraft emissions ( 42 U.S.C.   § 7571 ), and EPA began regulating in 1973. In 2012, EPA finalized its newest restrictions on NOx emissions from gas turbine aircraft engines with rated thrusts above 26.7 kiloNewton (3 short ton-force ), meaning primarily commercial jet aircraft engines, intended to match international standards. EPA has been investigating whether to regulate lead in fuels for small aircraft since 2010, but has not yet acted. The 1990 CAA Amendments ( Pub. L.   101–549 § 222) added rules for

6776-508: The standards used for controlling, reducing, and eliminating HAPs emissions from stationary sources such as industrial facilities. The 1970 CAA required EPA to develop a list of HAPs, and then develop national emissions standards for each of them. The original NESHAPs were health-based standards. The 1990 CAA Amendments ( Pub. L.   101–549 Title III) codified EPA's list, and required creation of technology-based standards according to "maximum achievable control technology" (MACT). Over

6864-551: The state does not adequately monitor requirements, the EPA may take control. The public may request to view the permits by contacting the EPA. The permit is limited to no more than five years and requires a renewal. One of the most public aspects of the Clean Air Act, EPA is empowered to monitor compliance with the law's many requirements, seek penalties for violations, and compel regulated entities to come into compliance. Enforcement cases are usually settled, with penalties assessed well below maximum statutory limits. Recently, many of

6952-470: The strict amendments, EPA Administrator William Ruckelshaus spent 60% of his time during his first term on the automobile industry, whose emissions were to be reduced 90% under the new law. Senators had been frustrated at the industry's failure to cut emissions under previous, weaker air laws. Major amendments were added to the Clean Air Act in 1977 (1977 CAAA) (91 Stat. 685, Pub. L.   95–95 ). The 1977 Amendments primarily concerned provisions for

7040-589: The symposium highlighted the National Environmental Policy Act's (NEPA) significant influence on promoting wilderness designation and constraining agency management practices in wilderness areas. Overall, the Wilderness Act remains a cornerstone of wilderness preservation, subject to ongoing refinement to ensure the enduring protection of these natural treasures. Over the decades, the Wilderness System has grown steadily. By

7128-622: The years, EPA has issued dozens of NESHAP regulations, which have developed NESHAPs by pollutant, by industry source category, and by industrial process. There are also NESHAPs for mobile sources (transportation), although these are primarily handled under the mobile source authorities. The 1990 amendments (adding CAA § 112(d-f)) also created a process by which EPA was required to review and update its NESHAPs every eight years, and identify any risks remaining after application of MACT, and develop additional rules necessary to protect public health. The New Source Performance Standards (NSPS) are rules for

7216-426: Was deemed to be insufficient. The Motor Vehicle Air Pollution Control Act ( Pub. L.   89–272 ) amended the 1963 Clean Air Act and set the first federal vehicle emissions standards, beginning with the 1968 models. These standards were reductions from 1963 emissions levels: 72% reduction for hydrocarbons , 56% reduction for carbon monoxide , and 100% reduction for crankcase hydrocarbons. . The law also added

7304-521: Was extended in 1959, 1960, and 1962 while Congress considered whether to regulate further. Beginning in 1963, Congress began expanding federal air pollution control law to accelerate the elimination of air pollution throughout the country. The new law's programs were initially administered by the U.S. Secretary of Health, Education, and Welfare , and the Air Pollution Office of the U.S. Public Health Service , until they were transferred to

7392-544: Was originally developed in 1972 and used driving cycles designed to simulate driving during rush-hour in Los Angeles during that era. Until 1984, EPA reported the exact fuel economy figures calculated from the test. In 1984, EPA began adjusting city (aka Urban Dynamometer Driving Schedule or UDDS ) results downward by 10% and highway (aka HighWay Fuel Economy Test or HWFET) results by 22% to compensate for changes in driving conditions since 1972, and to better correlate

7480-541: Was questioned by the court in West Virginia v. EPA (2022) but restored by Congress with the Inflation Reduction Act of 2022 , which clarified that carbon dioxide is one of the pollutants covered by the Clean Air Act. Standards for mobile sources have been established pursuant to Section 202 of the CAA, and GHGs from stationary sources are controlled under the authority of Part C of Title I of

7568-597: Was regarded as uncertain at the time. Early in the 88th Congressional term , the Senate debated and eventually passed the Wilderness Bill in April 1963. After President Kennedy's assassination , President Lyndon B Johnson continued the executive efforts for the Wilderness Act to be passed. During a press conference on June 23, 1963, President Johnson included the Wilderness Act as a piece of legislation that needed to be passed in his list of 30 "musts." After going to

7656-540: Was the first federal legislation to permit the U.S. federal government to take direct action to control air pollution. It extended the 1955 research program, encouraged cooperative state, local, and federal action to reduce air pollution, appropriated $ 95 million over three years to support the development of state pollution control programs, and authorized the HEW Secretary to organize conferences and take direct action against interstate air pollution where state action

7744-484: Was the vast untamed wilderness that was untouched by humans, which had fallen to about 2.5% of the total land in America by the 1960s. Previous efforts to conserve nature had yielded public land designations and protections such as the National Parks System , National Forests , and primitive areas . Unfortunately, many of these designations came short of providing the necessary protections needed to keep
