Exercise: The Case of the Contaminated Riverbank

Scenario: Imagine a contaminated riverbank is listed on the National Priorities List. The responsible party is a former industrial facility that discharged pollutants into the river. The EPA has conducted a remedial investigation and feasibility study (RI/FS) and is now preparing a Record of Decision (ROD).

Task:

• Identify three key factors that the EPA should consider when deciding on the cleanup alternative for the riverbank.
• For each factor, explain how it contributes to the effectiveness and feasibility of the chosen cleanup approach.
• Consider the potential impacts of different cleanup alternatives on the local community, environment, and economy.

Techniques

Chapter 1: Techniques for Developing a Record of Decision (ROD)

This chapter delves into the technical aspects of crafting a robust ROD. It outlines the key steps and considerations involved in selecting a cleanup strategy and documenting it within the ROD.

1.1. Remedial Investigation/Feasibility Study (RI/FS):

The foundation for a well-informed ROD lies in a thorough RI/FS. This process involves:

• Site Characterization: Defining the extent of contamination, identifying the nature and concentration of contaminants, and understanding the hydrogeology.
• Risk Assessment: Evaluating the potential risks posed by contaminants to human health and the environment.
• Cleanup Alternative Development: Generating a range of potential cleanup options, considering factors like effectiveness, cost, feasibility, and environmental impacts.
• Alternative Evaluation: Analyzing and comparing the cleanup alternatives based on defined criteria and evaluating their potential benefits and drawbacks.

1.2. Public Participation:

A critical component of the ROD process is involving the public and stakeholders. This ensures transparency and considers community concerns:

• Public Meetings: Hosting meetings to present the findings of the RI/FS, discuss the cleanup alternatives, and gather feedback.
• Public Comment Periods: Allowing for written submissions from the public, providing opportunities to address concerns and incorporate suggestions.
• Community Outreach: Utilizing various communication channels to disseminate information and engage with the public throughout the decision-making process.

1.3. Decision Analysis:

Following the RI/FS and public input, the responsible party, typically the EPA, evaluates the cleanup alternatives and selects the preferred option:

• Decision Criteria: Establishing clear criteria for evaluating the alternatives, encompassing factors like effectiveness, cost, long-term risk, feasibility, and public health.
• Decision Documentation: Clearly articulating the rationale for selecting the preferred alternative, addressing the strengths and weaknesses of each option, and justifying the chosen approach.

1.4. ROD Content:

The ROD must comprehensively document the chosen cleanup strategy, providing a detailed outline of the selected alternative, including:

• Cleanup Objectives: Defining the desired level of cleanup, outlining the specific goals for contaminant reduction, containment, or long-term management.
• Implementation Schedule: Establishing a timeline for implementing the chosen cleanup approach, specifying milestones and anticipated completion dates.
• Cost Estimates: Providing a detailed breakdown of the estimated costs associated with the selected cleanup, including remediation, monitoring, and long-term management.
• Monitoring and Evaluation: Outlining the plan for monitoring the effectiveness of the cleanup, including the frequency and types of monitoring activities.
• Public Participation: Summarizing the public involvement process, highlighting key concerns addressed and how they were incorporated into the decision-making process.

1.5. Legal Considerations:

The ROD serves as a legally binding document, establishing the framework for the cleanup. It must adhere to relevant environmental regulations and legal requirements.

1.6. Ongoing Review and Updates:

The ROD may require updates and revisions throughout the cleanup process to reflect new information, changing conditions, or adjustments in the implementation plan. These revisions should be documented and communicated to the public.

Chapter 2: Models for Assessing Cleanup Alternatives

This chapter explores different models and methodologies used to assess the effectiveness and feasibility of various cleanup alternatives.

2.1. Risk-Based Corrective Action (RBCA):

This model focuses on minimizing the risk posed by contaminants to human health and the environment. It involves:

• Risk Assessment: Quantifying the risks associated with different cleanup options.
• Risk Management: Developing and implementing strategies to minimize risks to acceptable levels.
• Risk Communication: Communicating risks to the public and stakeholders in a clear and understandable manner.

2.2. Life Cycle Cost Analysis (LCCA):

LCCA evaluates the total cost of a cleanup option over its entire life cycle, considering factors like:

• Initial Costs: Remediation, construction, and infrastructure development.
• Operating Costs: Maintenance, monitoring, and long-term management.
• Disposal Costs: Managing and disposing of contaminated materials.
• Future Costs: Potential long-term monitoring and maintenance requirements.

2.3. Decision Analysis Techniques:

These techniques provide structured approaches for comparing alternatives, considering factors like:

• Multi-Criteria Decision Analysis (MCDA): Weighing different criteria, such as cost, effectiveness, risk, and feasibility, to rank cleanup options.
• Sensitivity Analysis: Assessing the impact of uncertainties on the decision, helping to identify key factors influencing the preferred alternative.
• Scenario Planning: Exploring different future scenarios to evaluate the robustness of the selected cleanup option.

2.4. Modeling Tools:

Software tools and models are often used to support decision-making:

• Contaminant Transport Modeling: Simulating the movement of contaminants through the environment, aiding in the design of effective cleanup strategies.
• Risk Assessment Modeling: Quantifying the risks associated with different cleanup options, helping to inform decision-making.
• Cost Estimating Models: Providing accurate estimates of the costs associated with cleanup alternatives.

Chapter 3: Software Applications for ROD Development
