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]
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, Florida had 477.5 facilities that were regulated annually by the Clean Water Act. An average of 133.8 facilities violated the act annually from 2004 to 2007 in Florida, and the EPA enforced the act an average of 57.1 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 Florida compared to neighboring states in The New York Times study, including the number of regulated facilities, facility violations, and the annual average of enforcement actions against regulated facilities between 2004 and 2007.

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 Florida
There were 129 endangered and threatened animal and plant species believed to or known to occur in Florida as of July 2015.
The table below lists the 70 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]

State-listed species in Florida
The Florida Fish and Wildlife Conservation Commission (FWS) maintains the state's list of threatened species and "species of special concern." Florida law does not have a designation for "endangered" species; rather, Florida designates species as "threatened" if they are at risk of extinction. "Threatened" species under Florida's state list are all distinct from federally listed species. "Species of special concern" are species being studied and monitored by the state that have not received the designation of threatened.[9]
The table below shows the number of state-listed threatened species and species of special concern in Florida by status and species type. A complete list with the names and status of each species can be found here.

Enforcement
- See also: Enforcement at the EPA
Florida is part of the EPA's Region 4, which includes Kentucky, Alabama, Georgia, Mississippi, North Carolina, South Carolina and Tennessee.
The EPA enforces federal standards on 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 42.8 million pounds of pollution, which includes air pollution, water contaminants, and hazardous chemicals, were "reduced, treated or eliminated" and 16.6 million cubic yards of soil and water were cleaned in Region 4. Additionally, 420 enforcement cases were initiated, and 416 enforcement cases were concluded in fiscal year 2013. 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 amount of fines and penalties it collects during a fiscal year.[10][11][12][13]
Mercury and air toxics standards
- See also: Mercury and air toxics standards
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 730 premature deaths in Florida while creating up to $6 billion in health benefits in 2016."[14][15][16]
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 argued 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.[17]
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.[18]
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 186 Superfund sites reside in Region 4, with an average of 26.25 sites per state. There were 53 Superfund sites in Florida as of October 2014.[19][20]
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.[21]
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.[22]
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.[23][24]
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.[25]
Carbon emissions
- See also: Climate change, Greenhouse gas and Greenhouse gas emissions by state
In 2011, Florida ranked fifth in carbon emissions nationwide. Florida experienced a gradual increase in CO2 emissions between 1990 and 2011. Emissions peaked in 2005 when the state emitted 260 million metric tons of greenhouse gases, but emissions declined steadily from that peak year. The vast majority of greenhouse gas emissions in Florida come from the electric power and transportation sectors, which account for 48.7 percent and 44.5 percent of all emissions, respectively. The commercial, residential and industrial sectors accounted for the remainder.[26]

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.[27][28]
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.[29][30]
The chart below compares the annual average concentration of carbon monoxide in the Northeastern and Southeastern 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 Northeast, there were 32 monitoring sites throughout 11 states, compared to 22 monitoring sites throughout six states in the Southeast. In 2000, the average concentration of carbon monoxide was 2.7 ppm in the Northeast, compared to 3.91 ppm in the Southeast. In 2014, the average concentration of carbon monoxide was 1.2 ppm in the Northeast, a decrease of 61.1 percent from 2000, compared to 1.52 ppm in the Southeast, a decrease of 56.7 percent from 2000.[31]
Nitrogen dioxide (NO2)
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).[30][32][30]
The chart below compares the annual one-hour average concentration of nitrogen dioxide (NO2) in the Northeastern and Southeastern regions of the United States between 2000 and 2014. In the Northeast, there were 32 monitoring sites throughout 11 states, compared to 14 monitoring sites throughout six states in the Southeast. In 2000, the one-hour daily average concentration of NO2 was 61.31 ppb in the Northeast, compared to 57 ppb in the Southeast. In 2014, the one-hour daily average concentration of NO2 was 43.98 ppb in the Northeast, a decrease of 28.2 percent since 2000, compared to 38.36 ppb in the Southeast, a decrease of 32.6 percent since 2000.[33]
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.[30][34]
The chart below compares the daily eight-hour average concentration of ground-level ozone in the Northeastern and Southeastern 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 Northeast, there were 133 monitoring sites throughout 11 states, compared to 153 monitoring sites throughout six states in the Southeast. In 2000, the daily eight-hour average concentration of ozone was 0.083 ppm, or 83 ppb in the Northeast, compared to 0.082 ppm, or 82 ppb in the Southeast. In 2014, the daily eight-hour average concentration of ozone was 0.066 ppm, or 66 ppb in the Northeast, a decrease of 19.5 percent since 2000, compared to 0.063 ppm, or 63 ppb in the Southeast, a decrease of 23.9 percent since 2000.[35]
