Pollution Laws: State Vs Federal Jurisdiction

The relationship between federal and state governments shapes environmental laws and policies, with both parties sharing responsibilities. The Environmental Protection Agency (EPA) plays a crucial role in pollution laws, providing grants, establishing standards, and offering assistance to states. Federal laws like the Clean Air Act (CAA) and Clean Water Act (CWA) set minimum criteria for states to follow, allowing the EPA to intervene if states fail to comply. Federal laws may also preempt state legislation in areas like interstate commerce and navigable waters. On the other hand, states have direct influence over federal policy through enforcement decisions, and they often serve as testing grounds for future federal laws. The complexity of environmental issues means that regulations must be adaptable, and some problems are addressed at both federal and state levels.

The Clean Air Act and state regulators

In the United States, the Clean Air Act (CAA) is a federal law that regulates air emissions from stationary and mobile sources. The Act is administered by the Environmental Protection Agency (EPA), in coordination with state, local, and tribal governments. The EPA develops regulations and programs to carry out the law's mandates, and state regulators play a crucial role in implementing these programs.

One of the key aspects of the Clean Air Act is the establishment of National Ambient Air Quality Standards (NAAQS), which set acceptable levels for certain air pollutants in the ambient air. The EPA is responsible for determining which air pollutants pose the greatest threat to public health and welfare and establishing NAAQS for them. These standards include limits on ground-level ozone, carbon monoxide, particulate matter, lead, sulfur dioxide, and nitrogen dioxide.

The Clean Air Act also addresses emissions of hazardous air pollutants. Section 112 of the Act requires the EPA to establish emission standards, known as Maximum Achievable Control Technology (MACT) standards, for major sources of hazardous air pollutants. The Act further calls for states and the EPA to work together to address multiple air pollution problems through programs based on the latest science and technology.

State regulators have significant responsibilities under the Clean Air Act. They make permitting decisions regarding new sources of pollution and develop state implementation plans (SIPs) to achieve NAAQS. State and local agencies also issue permits for sources of volatile organic compounds (VOCs) and other pollutants. If a state does not adequately monitor and enforce these requirements, the EPA may step in and take control.

The relationship between state and federal regulators is complex and dynamic. While the Clean Air Act sets federal standards, states have flexibility in how they enforce these standards and can directly shape federal policy through their enforcement actions. Federal regulations often establish minimum criteria for state compliance, and the EPA encourages state and local governments to take environmental action through notification and assistance. In some cases, the EPA can countermand state decisions or take over enforcement if states do not meet federal standards or comply with specific guidelines.

Federal regulation of nonpoint source water pollution

Environmental laws and policies are shaped by the relationships between state and federal parties. While federal regulations of nonpoint source water pollution exist, localities often lack the incentive to enforce them, and federal enforcers cannot overrule state decisions. This has led to criticism that federal regulation in this area is weak.

Nonpoint source water pollution (NPS) comes from a wide range of sources and is difficult to regulate due to its varying nature over time and space. The primary nutrients found in water due to NPS are nitrogen and phosphorus from fertilizers, which can lead to eutrophication and the death of organisms.

There are two main federal laws that address NPS water pollution: the Clean Water Act (CWA) and the Coastal Zone Management Act. The CWA, passed in 1972, was the first federal law to address water pollution and has been amended several times since. While the CWA provides a specific legal definition of "nonpoint source", it does not include agricultural stormwater discharges and return flows from irrigated agriculture. The 1972 amendments created the National Pollutant Discharge Elimination System (NPDES) permit program and required states to prepare area-wide water quality management plans. Additional amendments in 1987 further addressed NPS water pollution.

The Environmental Protection Agency (EPA) has also implemented policies to address NPS water pollution. The EPA's "Clean Water Action Plan" (2009) outlines strategies for enforcing CWA requirements, some of which apply to nonpoint sources. The EPA also created its 2008 CAFO Rule, which allows the agency to treat land applications of excessive amounts of manure as a point source.

While the CWA and EPA policies provide a framework for addressing NPS water pollution, there are challenges in their implementation. States have broad discretion in implementing CWA nonpoint source pollution mandates, and their approaches vary. For example, California has implemented prescriptive regulations, while Oklahoma relies on voluntary measures and cost-sharing. The EPA has oversight authority for some aspects, but this authority has been unevenly applied and faced legal challenges.

In conclusion, while federal regulations of NPS water pollution exist, their effectiveness is impacted by the complex interplay between federal, state, and local authorities, as well as the varying nature of NPS pollution sources.

Federalism doctrine limits

Federalism, a basic concept embodied in the US Constitution, refers to the division and sharing of power between the national and state governments. The framers of the Constitution sought to establish a unified national government with limited powers while maintaining a sphere of autonomy for state governments to exercise a general police power.

Other examples of federalism doctrine limits include the state sovereign immunity doctrine and the equal sovereignty doctrine, which may constrain Congress's power to act even when it has legislative authority in a particular area. The "Anti-Coercion" doctrine, explained by the Supreme Court, states that conditions on federal funding cannot be unduly coercive, such as inducing states to engage in unconstitutional activities like racial discrimination or inflicting cruel and unusual punishment.

In the context of environmental laws and pollution, federalism doctrine limits come into play as well. Federal law may preempt state legislation in issues of interstate commerce or navigable waters, but federalism doctrine limits federal power in this area. For instance, federal policy regarding non-point water pollution is typically subsidies to states with plans to regulate emissions, partly because of the question of whether the federal government can regulate interstate land use as it relates to pollution. The Clean Air Act provides another example of conditional preemption, where state regulators make permitting decisions, but the Environmental Protection Agency (EPA) may countermand these decisions under certain circumstances.

While federalism doctrine limits seek to restrict the power of the federal government, it is worth noting that the federal government's reach has expanded over time, and it now has the ability to regulate almost every aspect of state affairs. This expansion has been facilitated by the interconnectedness of issues and the broad interpretation of the Commerce Clause.

The Environmental Protection Agency (EPA)

The EPA conducts environmental assessments, research, and education, and it has the responsibility of maintaining and enforcing national standards under various environmental laws, in consultation with state, tribal, and local governments. The agency's employees include engineers, scientists, environmental protection specialists, legal experts, public affairs specialists, financial professionals, and information technologists.

The EPA plays a crucial role in pollution prevention and control. For example, under the Clean Air Act, the EPA can countermand state permitting decisions regarding new sources of pollution. The EPA also has the authority to establish a national research and development program for air pollution prevention and control, facilitating coordination among relevant agencies. Additionally, the EPA provides grants to states for pollution control and promotes source reduction by businesses.

In some cases, the EPA can obtain state enforcement authority and even direct states to create entities to control and monitor specific types of pollution, such as solid waste pollution. The EPA has created guidelines, such as the Enforcement Response Policy, to address pollution problems. While states are not legally required to follow these guidelines, they serve as a measurement of compliance, influencing federal intervention.

The EPA has faced challenges and controversies. For instance, in 2017, the agency was implicated in allegations regarding the weed killer Roundup, with claims that it worked to quash a review of the product's potentially harmful ingredient, glyphosate.

State and local governments' roles

The state and local governments play a crucial role in shaping environmental laws and policies, often working in partnership with federal authorities to implement legislation such as the Clean Air Act. While the Environmental Protection Agency (EPA) sets policies and standards, state and local governments are responsible for the day-to-day work of enforcing these environmental protection measures.

State and local agencies have the authority to issue permits and develop rules and regulations to meet the EPA's standards. For instance, in California, the state's Air Resources Board (CARB) sets its own emissions limits and develops policies to combat climate change and reduce the public's exposure to toxic air contaminants. Each of California's 35 local air districts is then responsible for regional air quality planning and rulemaking to protect public health and the environment. Similarly, in New York, the state and city departments of environmental conservation and protection, respectively, have their own staff and budgets to enforce environmental measures.

State and local governments also have a strong hand in shaping the practical effect of federal regulation in areas where the federal government cannot directly intervene. They often serve as testing grounds for policies that may be later adopted as federal laws. This concept, known as "laboratories of democracy," highlights the importance of allowing states a free hand to experiment with different forms of regulation to identify the most effective approaches.

Furthermore, state and local governments are responsible for engaging with the public and gathering input to design and implement their environmental programs. They work with transportation agencies to support planning and projects that improve air quality and reduce greenhouse gas emissions. Additionally, states have the option to adopt programs that partially or completely delegate EPA's authorities to implement and enforce toxic emissions standards, provided they meet or exceed federal requirements.

Overall, while the EPA plays a vital role in setting policies and standards, the successful implementation of environmental protection measures relies heavily on the efforts of state and local governments, which are often closer to the issues and have a better understanding of the specific needs and challenges of their regions.
