Session Objectives Understand the methods used by a risk manager to set up clean-up goals and objectives. ¡ Understand how site redevelopment and available resources impact a projects’ clean-up goals. ¡ Understand how environmental policy may impact goals and objectives. ¡
Clean-up Goals and Objectives Defined Clean-up goal: cleanup levels that are expected to be achieved. ¡ Clean-up objective: provides a description of what the cleanup will accomplish. ¡
Clean-up Objectives Provide media specific objectives. ¡ Form the basis for development of cleanup options. ¡ Should not be too restrictive so as to limit alternative development. ¡ Specify acceptable cleanup concentrations for each contaminant of concern, medium, and route of exposure. ¡
Clean-up Objectives Reexamined prior to cleanup alternative development. ¡ Address all risks during all phases of cleanup action. ¡ May change if site conditions change. ¡ May change if site technical or nontechnical information changes. ¡
Example of a Clean-up Objective Prevent ingestion of or direct contact with soil contaminated with lead at levels above 500 parts per million by on-site workers and visitors in t he wood treatment and storage area. ¡ Prevent migration of lead that would result in groundwater contamination in excess of 50 parts per billion for lead. ¡
Factors to Consider When Developing Clean-up Goals Environmental policies ¡ Site reuse and its possible impacts ¡ Economics ¡ Other factors (politics, public perception, legal considerations) ¡
Environmental Policy Defined ¡ Policy is a broad course of action, guiding principles, or procedure, considered to be expedient, prudent, or advantageous.
Impact of Site Reuse May affect the level of cleanup at a site. ¡ May affect the selection of a cleanup option or alternative. ¡ May affect the selection of a cleanup technology. ¡
Economics ¡ Availability of Funding: l Available cleanup funds may limit the scope of site cleanup. Impact of the potential cleanup option on the local economy. ¡ Impact of the selected cleanup option on the national economy. ¡ The intrinsic value of a resource. ¡
Other Factors to Consider ¡ Technical factors. l l l ¡ Availability Feasibility Implementability Non-technical factors: l l Politics Legal issues Public perception Society's values
Session Summary Develop initial cleanup goals and objectives ¡ Revise cleanup goals and objectives ¡ Consider technical factors ¡ Consider non-technical factors ¡

Session Objectives Understand how clean-up alternatives are developed ¡ Understand how clean-up alternatives are screened ¡ Understand how a clean-up alternative is selected ¡
Selection of Clean-up Alternatives
Examples of General Clean-up Alternatives Treatment ¡ Engineering Controls ¡ Collection and Discharge ¡ Institutional Controls ¡ No Action ¡
Selection of Clean-up Alternatives
Technology Alternatives: Elements to Evaluate Site specific data ¡ Technical information ¡ A technology type needs to be identified for each general cleanup alternative ¡
Clean-up Alternative Technology Selection ¡ Technical Factors to Be Considered l l l Availability Feasibility Implementability
Clean-up Alternative Technical Information ¡ Risk Reduction Data l Impact of remedy on risk Short-term ¡ Long-term (performance) ¡
Selection of Clean-up Alternatives
Identification of Technology Process Options Identify the types of technologies that may be appropriate for a remedial alternative. ¡ Define specific process for each technology type. ¡ Identify representative examples of process options within a technology. ¡
Example of Screening Criteria Implementability ¡ Effectiveness ¡ Economic ¡ Political Issues ¡ Public Concern Issues ¡ Benefit Analysis ¡
Implementability Technically and Administratively Feasible ¡ Reliability, complexity, resources, etc. ¡ Technology is appropriate for site location ¡
Effectiveness Meets goals and objectives? ¡ Risks to receptors during implementation or construction of the technology? ¡ Reliability (track record)? ¡
Economic Issues ¡ Cost to implement l l l ¡ Direct Capital Indirect Capital Operation and Maintenance Returning site to economic reuse
Political Issues Objections to certain technologies ¡ Incentives for certain technologies ¡ Concern about cost and cost effectiveness ¡
Public Concern Issues ¡ Impact on community l l l l Noise Traffic Hazards Emissions Property values Time (how long will clean-up last? ) Future of the site (redevelopment)
Benefit Analysis ¡ Benefit analysis involves the comparison of: l l l Effects on Environmental Protection Costs Measure of Confidence
Types of Benefit Analysis Risk Benefit Analysis ¡ Cost-Effectiveness Analysis ¡
Evaluating Intangibles ¡ Consider Intangibles Subjectively l Such as: Preservation of Wilderness ¡ Quality of Life ¡
Choosing an Option Calculate cost per unit of benefit ¡ Factor in the intangibles ¡ Consider the overall affordability ¡ Cost/Benefit = Cost of Clean-up Alternative Benefits
Example of Option Selection ¡ Option 1: Groundwater Extraction with Off -site Treatment to Contain Pollution from Facility l l Cost Per Unit Benefit: ¡ 1 acre of wetland saved for every $1, 000 spent. Intangibles: ¡ Public acceptance, ¡ Wildlife Preserved, ¡ Localized depletion of groundwater resources leading to less water available for residential/industrial use nearby.
Example of Option Selection ¡ Option 2: Insitu Soilwashing and Groundwater Bioremediation l l l Cost Per Unit Benefit: ¡ 2 acres of wetlands saved for every $1, 000 spent Intangibles: ¡ Public unsure of long-term affects and success of remedy ¡ Timeframe for cleanup of groundwater is long - greater than 10 years. Overall Affordability: ¡ Within the cost of available funding
Example of Option Selection ¡ Option 3: Placement of a Contaminant Barrier (slurry wall) l l Cost per unit benefit: ¡ 4 acres of wetlands saved for every $1, 000 spent. Intangibles: ¡ Public uncertainty over effectiveness, ¡ Time frame for remediation is less short. ¡ Long-term effectiveness (greater than 15 to 20 years) is unknown
Cost Effectiveness Analysis
How to Measure Effectiveness Reduction in Toxicity ¡ Reduction in Volume ¡ Reduction in Mobility ¡
Asymptotic Curve ¡ Diminishing returns (risk reduction) on the investment (money) over time
Calculating Costs and Effectiveness ¡ A simple cost-effectiveness comparison might look like this: Option 1 is the most cost effective; however, in the scenario, 12. 5 additional miles of river could be cleaned-up for only $9, 000, which might be selected based on policy goals.

Session Objectives Familiarity of and utilization with the procedures to select a remedial option. ¡ Understanding of the importance of communicating the selected remedy to the public. ¡
Selecting the Remedy ¡ Questions to consider: l l Will a clean-up alternative meet risk management objectives? Is the remedy legal? Is the remedy technically and administratively implementable? Will the remedy be effective over time?
Selecting the Remedy (continued) ¡ Questions to consider: l l Will the clean-up cause more harm then good? What is the opinion of the public and other stakeholders? Is the remedy cost-effective? Are resources available to design and implement the remedy?
Documenting the Decision ¡ Purpose of Decision l l Public awareness and input Engineering use Legal record Decision record
