• Expert judgment: Utilizing the knowledge and experience of specialists to assess potential impacts.

1.3 Impact Prediction and Significance Evaluation

• Magnitude: Estimating the size or extent of potential impacts.
• Duration: Determining the length of time the impact will last.
• Reversibility: Assessing whether the impact can be reversed or mitigated.
• Probability: Estimating the likelihood of the impact occurring.
• Significance: Determining the overall importance of the impact based on its magnitude, duration, reversibility, and probability.

1.4 Mitigation Measures

• Design modifications: Adapting the project design to minimize environmental impacts.
• Operational changes: Implementing operational procedures to reduce pollution or conserve resources.
• Compensatory measures: Implementing actions to offset negative impacts, such as habitat restoration or carbon offsetting.
• Monitoring and evaluation: Regularly assessing the effectiveness of mitigation measures and adjusting them as needed.

1.5 Environmental Impact Statement (EIS)

• Content: The EIS is a comprehensive report that summarizes the findings of the EIA and provides a detailed analysis of the project's potential environmental impacts, proposed mitigation measures, and alternatives considered.
• Public consultation: The EIS is made available to the public for review and comment, ensuring transparency and stakeholder engagement.

Chapter 2: Models

This chapter explores various models employed for assessing the environmental impact of waste management practices and projects.

2.1 Landfill Gas Modeling

• Predicting gas production: Models simulate the generation and movement of landfill gas, including methane, carbon dioxide, and other volatile organic compounds.
• Assessing risks: Analyzing the potential for gas migration and the impact on surrounding areas, including air quality and greenhouse gas emissions.

2.2 Water Quality Modeling

• Simulating leachate transport: Models analyze the flow of leachate, a contaminated liquid generated in landfills, through the soil and groundwater.
• Assessing water contamination risks: Identifying potential pathways of contamination and predicting the impact on nearby water bodies and drinking water sources.

2.3 Air Dispersion Modeling

• Predicting air pollutant dispersal: Models estimate the dispersion of air pollutants emitted from waste management facilities, considering factors like wind speed, direction, and atmospheric conditions.
• Analyzing air quality impacts: Assessing the potential for exceeding air quality standards and the impact on human health and the environment.

2.4 Life Cycle Assessment (LCA)

• Evaluating environmental impacts of waste management systems: LCA models assess the environmental burden associated with different waste management options, from raw material extraction to disposal.
