Environmental Science: Environmental Policy and the EPA

How laws, regulations, and the EPA protect people and the environment

Environmental Science - Grade 9-12

Instructions: Read each problem carefully. Use complete sentences and include evidence or examples when possible.
  1. 1

    Define environmental policy in your own words. Include one example of a goal an environmental policy might try to achieve.

    Think about rules that protect air, water, land, wildlife, or public health.

    Environmental policy is a set of laws, rules, or actions used by governments or organizations to manage human impacts on the environment. One goal might be to reduce air pollution so that people have cleaner air to breathe.
  2. 2

    Explain the main role of the Environmental Protection Agency, also called the EPA, in the United States.

    The EPA is a federal agency that helps protect human health and the environment. It does this by enforcing environmental laws, setting pollution standards, monitoring environmental quality, and providing information to the public.
  3. 3

    A factory releases smoke that contains pollutants into the air. Identify one type of EPA action that could address this problem and explain how it would help.

    Consider permits, inspections, fines, or pollution limits.

    The EPA could set and enforce limits on the amount of pollutants the factory may release. This would help reduce harmful emissions and improve air quality for nearby communities.
  4. 4

    Compare a law and a regulation in environmental policy.

    A law is passed by a legislative body, such as Congress, and gives broad legal requirements. A regulation is a more detailed rule created by an agency, such as the EPA, to explain how the law will be carried out and enforced.
  5. 5

    The Clean Air Act is a major U.S. environmental law. Describe one reason this law is important.

    Focus on how air pollution can affect health, ecosystems, or visibility.

    The Clean Air Act is important because it gives the EPA authority to regulate air pollutants that can harm human health and the environment. It helps reduce problems such as smog, acid rain, and exposure to toxic air pollution.
  6. 6

    The Clean Water Act focuses on protecting surface waters such as rivers, lakes, and wetlands. Give one example of a pollution source this law could help control.

    The Clean Water Act could help control wastewater released from a factory or sewage treatment plant. It can require permits and treatment standards so that polluted water is not discharged directly into waterways.
  7. 7

    Describe what an environmental impact statement is and why it may be required before a large project is approved.

    Think about roads, dams, pipelines, airports, or large buildings.

    An environmental impact statement is a detailed report that predicts how a proposed project could affect the environment. It may be required so decision makers and the public can understand possible impacts before construction or approval begins.
  8. 8

    A city wants to build a new highway through a wetland. List two environmental concerns that policy makers should consider before approving the project.

    Policy makers should consider whether the highway would destroy wetland habitat and whether runoff from the road would pollute nearby water. They should also consider effects on flood control, wildlife movement, and local communities.
  9. 9

    Explain how scientific data can influence environmental policy decisions.

    Examples of data include measurements, maps, experiments, and long-term monitoring records.

    Scientific data can show the size, cause, and effects of an environmental problem. Policy makers can use data on pollution levels, health risks, climate trends, or ecosystem changes to create rules that are based on evidence.
  10. 10

    A regulation requires power plants to reduce mercury emissions. Explain one possible benefit and one possible cost of this regulation.

    One benefit is that less mercury would enter air, water, and food webs, which can reduce health risks for people and wildlife. One possible cost is that power plants may need to spend money on new pollution control technology.
  11. 11

    Explain the idea of environmental justice and why it matters in environmental policy.

    Think about fairness in where pollution sources are located and who gets a voice in decisions.

    Environmental justice means that all people should have fair protection from environmental hazards and fair involvement in environmental decisions. It matters because some communities have historically faced higher pollution burdens and fewer resources to respond.
  12. 12

    Write a short policy recommendation for reducing plastic pollution in a local community. Include one specific action and one reason it could be effective.

    A community could require stores and restaurants to reduce single-use plastic bags and containers. This could be effective because it would lower the amount of plastic waste produced and encourage people to use reusable or recyclable alternatives.
