Federal environmental regulation involves the implementation of federal environmental laws, such as the Clean Air Act, Clean Water Act, and the Endangered Species Act. The U.S. Environmental Protection Agency (EPA) is primarily responsible for enforcing federal air and water quality standards; the U.S. Fish and Wildlife Service is primarily responsible for managing endangered species. State government agencies will often share enforcement responsibilities with the EPA on issues such as air pollution, water pollution, hazardous waste, and other environmental issues.[1]

As of July 2015, Wyoming had 11 federally protected species, 795 federally regulated drinking water systems, and two federally regulated waste sites (known as Superfund sites).

Legislation and regulation

Federal laws

Clean Air Act

The federal Clean Air Act requires each state to meet federal standards for air pollution. Under the act, the U.S. Environmental Protection Agency oversees national air quality standards aimed at limiting pollutants from chemical plants, steel mills, utilities, and industrial factories. Individual states can enact stricter air standards if they choose, though each state must adhere to the EPA's minimum pollution standards. States implement federal air standards through a state implementation plan (SIP), which must be approved by the EPA.[2]

Clean Water Act

The federal Clean Water Act is meant to address and maintain the physical, chemical, and biological status of the waters of the United States. The U.S. Environmental Protection Agency (EPA) regulates water pollution sources and provides financial assistance to states and municipalities for water quality programs.[3]

According to research done by The New York Times using annual averages from 2004 to 2007, Wyoming had 1,627.5 facilities that were regulated annually by the Clean Water Act. An average of 6.3 facilities violated the act annually from 2004 to 2007 in Wyoming, and the EPA enforced the act an average of 27 times a year in the state. This information, published by the Times in 2009, was the most recent information on the subject as of October 2014.[4]

The table below shows how Wyoming compared to neighboring states in The New York Times study, including the number of facilities regulated, facility violations, and the annual average enforcement actions against these facilities between 2004 and 2007. Wyoming had the most facilities regulated under the Clean Water Act compared to neighboring states.

Endangered Species Act

The federal Endangered Species Act (ESA) of 1973 provides for the identification, listing, and protection of both threatened and endangered species and their habitats. According to the U.S. Fish and Wildlife Service, the law was designed to prevent the extinction of vulnerable plant and animal species through the development of recovery plans and the protection of critical habitats. ESA administration and enforcement are the responsibility of the U.S. Fish and Wildlife Service and the National Marine Fisheries Service.[5][6]

Federally listed species in Wyoming

There were 11 endangered and threatened animal and plant species believed to or known to occur in Wyoming as of July 2015.

The table below lists the seven endangered and threatened animal species believed to or known to occur in the state. When an animal species has the word "Entire" after its name, that species will be found all throughout the state.[7]

Enforcement

See also: Enforcement at the EPA

Wyoming is part of the EPA's Region 8, which includes South Dakota, North Dakota, Colorado, Utah and Montana.

The EPA enforces federal standards for air, water and hazardous chemicals. The EPA takes administrative action against violators of environmental laws, or brings civil and/or criminal lawsuits, often with the goal of collecting penalties/fines and demanding compliance with laws like the Clean Air Act and Clean Water Act. In 2013, the EPA estimated that 9.2 million pounds of pollution, which includes air pollution, water contaminants, and hazardous chemicals, were "reduced, treated or eliminated" and 7.04 million cubic yards of soil and water were treated in Region 8. Additionally, 152 enforcement cases were initiated, and 161 enforcement cases were concluded in fiscal year 2013 in Region 8. In fiscal year 2012, the EPA collected $252 million in criminal fines and civil penalties from the private sector nationwide. In fiscal year 2013, the EPA collected $1.1 billion in criminal fines and civil penalties from the private sector nationwide, primarily due to the $1 billion settlement from the Deepwater Horizon oil spill along the Gulf Coast in 2010. The EPA only publishes nationwide data and does not provide state or region-specific information on the fines and penalties it collects each fiscal year.[8][9][10][11]

Mercury and air toxics standards

See also: Mercury and air toxics standards
The EPA on mercury capture systems

The EPA enforces mercury and air toxics standards (MATS), which are national limits on mercury, chromium, nickel, arsenic and acidic gases from coal- and oil-fired power plants. Power plants are required to have certain technologies to limit these pollutants. In December 2011, the EPA issued greater restrictions on the amount of mercury and other toxic pollutants produced by power plants. As of 2014, approximately 580 power plants, including 1,400 oil- and coal-fired electric-generating units, fell under the federal rule. The EPA has claimed that power plants account for 50 percent of mercury emissions, 75 percent of acidic gases and around 20 to 60 percent of toxic metal emissions in the United States. All coal- and oil-fired power plants with a capacity of 25 megawatts or greater are subject to the standards. The EPA has claimed that the standards will "prevent up to 6 premature deaths in Wyoming while creating up to $49 million in health benefits in 2016."[12][13][14][12][15]

In 2014, the EPA released a study examining the economic, environmental, and health impacts of the MATS standards nationwide. Other organizations have released their own analyses about the effects of the MATS standards. Below is a summary of the studies on MATS and their effects as of November 2014.

EPA study
In 2014, the EPA reported that its MATS rule would prevent roughly 11,000 premature deaths and 130,000 asthma attacks nationwide. The agency also anticipated between $37 billion and $90 billion in "improved air quality benefits" annually. For the rule's cost, the EPA estimated that annual compliance fees for coal- and oil-fired power plants would reach $9.6 billion.[16]

NERA study
A 2012 study published by NERA Economic Consulting, a global consultancy group, reported that annual compliance costs in the electricity sector would total $10 billion in 2015 and nearly $100 billion cumulatively up through 2034. The same study found that the net impact of the MATS rule in 2015 would be the income equivalent of 180,000 fewer jobs. This net impact took into account the job gains associated with the building and refitting of power plants with new technology.[17]

Superfund sites

The EPA established the Superfund program as part of the Comprehensive Environmental Response, Compensation and Liability Act of 1980.The Superfund program focuses on uncontrolled or abandoned hazardous waste sites nationwide. The EPA inspects waste sites and establishes cleanup plans for them. The federal government can compel the private entities responsible for a waste site to clean the site or face penalties. If the federal government cleans a waste site, it can force the responsible party to reimburse the EPA or other federal agencies for the cleanup's cost. Superfund sites include oil refineries, smelting facilities, mines and other industrial areas. As of October 2014, there were 1,322 Superfund sites nationwide. A total of 54 Superfund sites reside in Region 8, with an average of nine sites per state. There were two Superfund sites in Wyoming as of October 2014.[18][19]

Economic impact
EPA studies
The Environmental Protection Agency publishes studies to evaluate the impact and benefits of its policies. Other studies may dispute the agency's findings or state the costs of its policies.

According to the U.S. Government Accountability Office (GAO), an independent federal agency, the Superfund program received an average of almost $1.2 billion annually in appropriated funds between the years 1981 and 2009, adjusted for inflation. The GAO estimated that the trust fund of the Superfund program decreased from $5 billion in 1997 to $137 million in 2009. The Superfund program received an additional $600 million in federal funding from the American Recovery and Reinvestment Act of 2009, also known as the stimulus bill.[20]

In March 2011, the EPA claimed that the agency's Superfund program produced economic benefits nationwide. Because Superfund sites are added and removed from a prioritized list on a regular basis, the total number of Superfund sites since the program's inception in 1980 is unknown. Based on a selective study of 373 Superfund sites cleaned up since the program's inception, the EPA estimated these economic benefits include the creation of 2,240 private businesses, $32.6 billion in annual sales from new businesses, 70,144 jobs and $4.9 billion in annual employment income.[21]

Other studies were published detailing the costs associated with the Superfund program. According to the Property and Environment Research Center, a free market-oriented policy group based in Montana, the EPA spent over $35 billion on the Superfund program between 1980 and 2005.[22][23]

Environmental impact

In March 2011, the EPA claimed that the Superfund program resulted in healthier environments surrounding former waste sites. An agency study analyzed the program's health and ecological benefits and focused on former landfills, mining areas, and abandoned dumps that were cleaned up and renovated. As of January 2009, out of the approximately 500 former Superfund sites used for the study, roughly 10 percent became recreational or commercial sites. Other former Superfund sites in the study became wetlands, meadows, streams, scenic trails, parks, and habitats for plants and animals.[24]

Carbon emissions

See also: Climate change, Greenhouse gas and Greenhouse gas emissions by state

In 2011, Wyoming ranked 32nd in total carbon emissions nationwide. Emissions peaked in the state in 2008 at 67 million metric tons of CO2. In 2011, Wyoming's electric power sector accounted for the vast majority of carbon emissions (64.4 percent) followed by the industrial sector (20.4 percent) and the transportation sector (11.9 percent). The commercial and residential sectors accounted for the remainder.[25]

Pollution from energy use

Pollution from energy use includes three common air pollutants: carbon monoxide, nitrogen dioxide and ozone. These and other pollutants are regulated by the U.S. Environmental Protection Agency (EPA) through the National Ambient Air Quality Standards, which are federal standards limiting pollutants that can harm human health in significant concentrations. Carbon dioxide, a greenhouse gas, is also regulated by the EPA, but it is excluded here since it is not one of the pollutants originally regulated under the Clean Air Act for its harm to human health.

Industries and motor vehicles emit carbon monoxide directly when they use energy. Nitrogen dioxide forms from the emissions of automobiles, power plants and other sources. Ground level ozone (also known as tropospheric ozone) is not emitted but is the product of chemical reactions between nitrogen dioxide and volatile organic chemicals. The EPA tracks these and other pollutants from monitoring sites across the United States. The data below shows nationwide and regional trends for carbon monoxide, nitrogen dioxide and ozone between 2000 and 2014. States with consistent climates and weather patterns were grouped together by the EPA to make up each region.[26][27]

Carbon monoxide (CO)

Carbon monoxide (CO) is a colorless, odorless gas produced from combustion processes, e.g., when gasoline reacts rapidly with oxygen and releases exhaust; the majority of national CO emissions come from mobile sources like automobiles. CO can reduce the oxygen-carrying capacity of the blood and at very high levels can cause death. CO concentrations are measured in parts per million (ppm). Since 1994, federal law prohibits CO concentrations from exceeding 9 ppm during an eight-hour period more than once per year.[28][29]

The chart below compares the annual average concentration of carbon monoxide in the Northern Rockies/Plains and Northwestern regions of the United States between 2000 and 2014. States with consistent climates and weather patterns are grouped together by the U.S. Environmental Protection Agency (EPA), which collects these data, to make up each region. Each line represents the annual average of all the data collected from pollution monitoring sites in each region. In the Northwest, there were three monitoring sites throughout three states, compared to one monitoring site for five states in the Northern Rockies/Plains. In 2000, the average concentration of carbon monoxide was 3.93 ppm in the Northwest, compared to 5.5 ppm in the Northern Rockies/Plains. In 2014, the average concentration of carbon monoxide was 1.73 ppm in the Northwest, a decrease of 55.9 percent from 2000, compared to 2.6 ppm in the Northern Rockies/Plains, a decrease of 52.7 percent from 2000.[30]

Nitrogen dioxide (NO2)

Note: Annual data on nitrogen dioxide levels in the Northwest between 2000 and 2014 are unavailable.

Nitrogen dioxide (NO2) is one of a group of gasses known as nitrogen oxides (NOx). The U.S. Environmental Protection Agency (EPA) measures NO2 as a representative for the larger group of nitrogen oxides. NO2 forms from the emissions of cars, buses, trucks, power plants, and off-road equipment. It helps form ground-level ozone and fine particle pollution, and has been linked to respiratory problems. Since 1971, federal law prohibits NO2 concentrations from exceeding a daily one-hour average of 100 parts per billion (ppb) and an annual average of 53 parts per billion (ppb).[29][31][29]

The chart below compares the annual one-hour average concentration of nitrogen dioxide (NO2) in the Northern Rockies/Plains and Southwestern regions of the United States between 2000 and 2014. In the Northern Rockies/Plains, there were five monitoring sites throughout five states, compared to 10 monitoring sites throughout four states in the Southwest. In 2000, the one-hour daily average concentration of NO2 was 28.2 ppb in the Northern Rockies/Plains, compared to 71.5 ppb in the Southwest. In 2014, the one-hour daily average concentration of NO2 was 23.56 ppb in the Northern Rockies/Plains, a decrease of 16.4 percent from 2000, compared to 49.35 ppb in the Southwest, a decrease of 30.9 percent from 2000.[32]

Rockies-Southwest regional comparison.png

Ground-level ozone

Ground-level ozone is created by chemical reactions between nitrogen oxides (NOx) and volatile organic compounds (VOCs) in sunlight. Major sources of NOx and VOCs include industrial facilities, electric utilities, automobiles, gasoline vapors, and chemical solvents. Ground-level ozone can produce health problems for children, the elderly, and asthmatics. Since 2008, federal law has prohibited ozone concentrations from exceeding a daily eight-hour average of 75 parts per billion (ppb). Beginning in 2025, federal law will prohibit ground-level ozone concentrations from exceeding a daily eight-hour average of 70 ppb.[29][33]

The chart below compares the daily eight-hour average concentration of ground-level ozone in the Northern Rockies/Plains and Northwestern regions of the United States between 2000 and 2014. In the chart below, ozone concentrations are measured in parts per million (ppm), which can be converted to parts per billion (ppb). In the Northern Rockies/Plains, there were 12 monitoring sites throughout five states, compared to 17 monitoring sites throughout three states in the Northwest. In 2000, the daily eight-hour average concentration of ozone was 0.0598 ppm, or 59.8 ppb in the Northern Rockies/Plains, compared to 0.0599 ppm, or 59.9 ppb in the Northwest. In 2014, the daily eight-hour average concentration of ozone was 0.0578 ppm, or 57.8 ppb in the Northern Rockies/Plains, a decrease of 3.3 percent from 2000, compared to 0.059 ppm, or 56.9 ppb in the Northwest, a decrease of 5 percent from 2000.[34]
