Environmental Policy and Regulation

Learning Objectives

  • Contrast key environmental health regulatory agencies.

  • State four principles guiding environmental policy development.

  • Compare five major environmental laws.

  • Describe policies protecting vulnerable groups.

  • Apply policy-making steps to examples.

Introduction

  • Environmental policies are crucial frameworks to mitigate hazards and protect public health. Governmental and international agencies develop, adopt, and enforce these policies, covering air quality, water purity, toxic substances, and ecological preservation. Policy formulation balances political influences, economic considerations, and scientific knowledge.

Role of Policy and Environmental Challenges

  • Environmental exposures significantly impact human health. Despite substantial investments, challenges persist (e.g., lead contamination, pesticide use, air pollution). Disproportionate burdens on marginalized communities highlight environmetal hazards as a human rights issue. Vulnerable populations like children require special protection due to their developing systems and higher exposure rates.

Overview of Environmental Policy Process

  • An environmental policy guides decisions for environmental protection and resource management, based on key principles and a structured cycle. A "systems approach" integrates scientific understanding, economic analysis, social values, and technological capabilities. Economic factors (industry interests, compliance costs, green growth potential) heavily influence policy feasibility and enforcement.

Principles of Environmental Policy Development

  • Precautionary Principle: Take preventive action against potential harm even with scientific uncertainty, shifting the burden of proof to those proposing activities.

  • Environmental Justice: Ensure all people have equal protection from environmental hazards and equal enjoyment of benefits, addressing disproportionate impacts on marginalized communities.

  • Environmental Sustainability: Meet present needs without compromising future generations' ability to meet their own, through responsible resource management and eco-friendly practices.

  • Polluter-Pays Principle: Those who cause pollution bear the costs of managing it, encouraging reduction and accountability.

The Policy Cycle

  1. Problem Definition: Identify and articulate the environmental health problem, using research, data, and stakeholder input.

  2. Agenda Setting: Gain attention from policymakers and the public through advocacy, media, and evidence.

  3. Policy Establishment: Develop and formally adopt specific policies (legislation, regulations, orders), often involving negotiation.

  4. Implementation: Put policy into practice by allocating resources, designing programs, monitoring compliance, and enforcing regulations.

  5. Assessment/Evaluation: Systematically evaluate policy effectiveness (environmental and health outcomes, economic impacts, social equity), providing feedback for revisions or new problems.

Risk Assessment and Policy Development

  • Risk assessment characterizes potential health risks from environmental hazards (hazard identification, dose-response, exposure, risk characterization). It informs policy by balancing mitigation costs against health benefits. Uncertainties (scientific data, multiple exposures, long latency) can hinder comprehensive policy development.

Risk Management

  • Risk management involves deciding how to control or reduce identified risks to acceptable levels. This includes establishing new standards, implementing pollution control, or banning harmful substances. Legislation, regulations, and community participation are key tools.

Environmental Impact Assessment (EIA) and Health Impact Assessment (HIA)

  • EIA: Predicts and evaluates environmental consequences of proposed actions to integrate environmental factors into decision-making.

  • HIA: Systematically determines potential health effects of proposed actions on populations and their distribution, aiming to maximize positive and minimize negative health outcomes, often complementing EIA.

Case Studies: Environmental Policies

  • The EPA Strategic Plan outlines goals for climate change, air/water quality, and toxic substance management. EPA also protects vulnerable environments (wetlands, national parks) and populations disproportionately affected by pollution, ensuring equitable protection.

Agencies Involved in Environmental Policies

  • EPA: US federal agency managing environmental laws, setting standards, monitoring compliance, funding programs, and conducting research.

  • WHO: UN specialized agency providing global leadership on public health, guiding international policies, and monitoring disease outbreaks, linking environmental factors to health.

  • NIOSH: Federal agency researching and recommending prevention of work-related injury and illness, focusing on worker safety in environmental/occupational settings.

  • Collaborative efforts among agencies are essential for comprehensive, effective, and harmonized environmental policies.

Major US Environmental Health Laws

  • Clean Air Act (CAA) (1970): Authorizes EPA to establish National Ambient Air Quality Standards (NAAQS) and regulate emissions from stationary/mobile sources, significantly reducing pollutants.

  • Clean Water Act (CWA) (1972): Regulates pollutant discharges into surface waters, prohibits unpermitted point source discharges, and funds sewage treatment, aiming to restore water integrity.

  • Safe Drinking Water Act (SDWA) (1974): Protects public drinking water by authorizing EPA to set national health-based standards for over 90 contaminants.

  • National Environmental Policy Act (NEPA) (1969): Requires federal agencies to assess environmental effects of proposed actions via Environmental Impact Statements (EIS), promoting informed decision-making.

  • Toxic Substances Control Act (TSCA) (1976): Grants EPA authority to regulate chemical substances posing unreasonable risks, allowing for reporting, testing, restrictions, or bans on harmful chemicals.

Conclusion

  • Effective environmental policies and their rigorous enforcement are critical for public health and societal well-being. The challenge lies in balancing protection from environmental hazards with long-term sustainability, ensuring a healthy planet for present and future generations amidst economic and social pressures.
