Command-And-Control: Government's Pollution Solution?

A command-and-control approach (CAC) is a method governments use to reduce and limit pollution. This approach involves policymakers and political authorities mandating companies to act in specific ways to manage pollution. The government sets up different authorities to impose fines and punishments for companies that do not comply with environmental laws. This approach has been effective in the US, with the Clean Air Act and Clean Water Act being successful examples of reducing pollution and improving air and water quality. However, economists have identified some challenges with this approach, including a lack of incentives for companies to go beyond the minimum requirements and its inflexibility in accommodating different types of companies.

The Clean Air Act

The 1970 Clean Air Act authorized the Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) to protect public health and the environment. The Act set a goal of achieving NAAQS in every state by 1975, addressing the risks posed by widespread air pollutants to public health and welfare. The states were directed to develop State Implementation Plans (SIPs), consisting of emission reduction strategies, to achieve these standards.

The 1977 amendments to the CAA set more stringent requirements for reducing emissions in areas that did not meet the NAAQS. These amendments also established the Prevention of Significant Deterioration (PSD) regulations for areas that already met the NAAQS, aiming to prevent any significant deterioration in air quality.

The 1990 amendments to the Clean Air Act were designed to address issues that had not been sufficiently tackled, including acid rain, ground-level ozone, stratospheric ozone depletion, visibility, and air toxics. These amendments also established a national operating permits program and strengthened enforcement mechanisms to ensure better compliance with the Act.

Since the implementation of the Clean Air Act, there has been significant progress in reducing air pollution in the United States, preventing hundreds of thousands of cases of serious health effects each year. Despite this progress, air pollution continues to harm people's health and the environment, and the EPA continues to work towards improving air quality.

The Clean Water Act

A command-and-control approach is when the government implements controls to reduce and limit pollution. This approach is characterised by policymakers and political authorities mandating companies to act in certain ways to manage pollution. The government also sets up authorities to impose fines and other punishments for companies that do not obey environmental laws.

The CWA made it unlawful to discharge any pollutant from a point source into navigable waters without a permit. The EPA's National Pollutant Discharge Elimination System (NPDES) permit program controls these discharges. Point sources include pipes and man-made ditches. Industrial, municipal, and other facilities must obtain permits if their discharges go directly into surface waters.

The CWA also funded the construction of sewage treatment plants and recognised the need for planning to address the critical problems posed by nonpoint source pollution. The EPA has also developed national water quality criteria recommendations for pollutants in surface waters. Under the CWA, the EPA regulates all waste streams generated from offshore oil and gas activities, primarily by general permits. The EPA may not issue a permit for a discharge into ocean waters unless the discharge complies with the guidelines established under Section 403(c) of the CWA, which aim to prevent degradation of the marine environment.

The CWA is the primary law governing pollution control and water quality in the nation's waterways. The objective of the CWA is to restore and maintain the chemical, physical, and biological integrity of the nation's waters.

The Environmental Protection Agency (EPA)

The EPA plays a crucial role in implementing and enforcing command-and-control regulations, which have been effective in protecting and cleaning up the US environment. These regulations involve setting specific limits on pollution emissions and mandating the use of certain pollution-control technologies. For example, the EPA can specify how much pollution is allowed to be emitted from a smokestack or drainpipe, with penalties imposed on companies that exceed these limits.

One notable success of the EPA's command-and-control approach is the Clean Air Act, enacted in 1970 to tackle air pollution. Two years later, in 1972, the EPA also played a key role in the passage of the Clean Water Act, which addressed water pollution issues. These laws, along with their subsequent amendments and updates, have contributed significantly to improving air and water quality in the US.

However, despite its achievements, the EPA's command-and-control approach has faced some criticism from economists who have identified certain limitations. One criticism is the lack of incentives for companies to go beyond the minimum requirements set by the regulations. Once a company complies with the regulations, there is little motivation for further environmental improvement. Additionally, the command-and-control regulations are often seen as inflexible, as they typically apply uniform standards and technologies across different types of companies without considering their unique circumstances. This lack of differentiation can result in an unequal distribution of the social cost of pollution among companies.

Furthermore, the EPA's regulations are subject to political influence, with existing firms lobbying for exemptions from stricter environmental standards. As a result, environmental laws may end up containing loopholes and exceptions that favour specific interest groups.

Despite these criticisms, the EPA continues to play a vital role in protecting the environment and public health through its command-and-control approach. The agency has the authority to set standards, enforce regulations, and impose penalties on polluters, providing a necessary framework for pollution reduction in the US.

Effluent standards

A command-and-control approach (CAC) is a strategy where governments establish controls to minimise and curb pollution. This approach involves policymakers and political authorities mandating companies to take specific actions to manage pollution effectively. The government also sets up separate entities to impose fines and other penalties for companies that fail to comply with environmental laws.

One critical aspect of the CAC approach is the implementation of effluent standards, which are essential for managing wastewater and sewage treatment. Effluent standards, also known as Effluent Guidelines, are national regulatory standards set by the Environmental Protection Agency (EPA) in the United States. These standards specifically address wastewater discharged into surface waters and municipal sewage treatment plants. The EPA issues these regulations based on the performance of treatment and control technologies for various industrial categories.

The Effluent Guidelines play a crucial role in ensuring that industries adhere to specified levels of control, such as BPT (Best Practicable Control Technology), BAT (Best Available Technology), BCT (Best Conventional Control Technology), NSPS (New Source Performance Standards), PSNS (Pretreatment Standards for New Sources), and PSES (Pretreatment Standards for Existing Sources). These levels of control ensure that industries implement the most effective technologies to treat and control their wastewater discharges.

The EPA also mandates that pollutant discharges regulated by the Effluent Guidelines must be measured using approved analytical methods. This ensures that industries accurately monitor and report their pollutant discharges, promoting transparency and accountability. The guidelines cover a range of industries, including steam electric power generation, meat and poultry production, oil and gas extraction, and electrical and electronic components manufacturing.

By enforcing these effluent standards, the government can effectively control water pollution and protect the environment. These regulations push industries to invest in advanced treatment technologies, reduce their pollutant discharges, and minimise the environmental impact of their operations. The CAC approach, with its effluent standards, provides a structured framework for industries to follow, helping them understand their responsibilities and the consequences of non-compliance.

Incentive approaches

A classic example of an incentive approach is an emissions tax. This is a tax imposed on every unit of pollutive emissions. This provides an incentive for polluters to reduce their emissions until the marginal benefit gained from emissions is equal to the marginal cost of the emission tax.

Another type of incentive approach is marketable pollution permits. Each permit allows its owner to produce a certain amount of pollution per month or year. The permits can be bought or sold, with the market allocating them to the highest bidder. This incentivises owners to produce the most they can with each permit.

Subsidies are another incentive approach. Instead of imposing a tax, the government offers subsidies to companies that reduce their pollution discharges. If a company can reduce its pollution discharge at a cost that is less than the amount it would receive from the subsidy, then it will probably do so. This also incentivises companies to find novel approaches to pollution control.

Deposit-refund systems are another example of an incentive approach. For example, a beverage container recycling program would involve a product charge or tax on purchasing the container, with a subsidy rewarded to the consumer for recycling or properly disposing of the container.
