This option is primarily used as a baseline for comparison with other options., Estimated Cost: $0.00, 2., Monitoring and Institutional Controls, - Leave the TLM in place and restrict access to the area by placing signs in and along the river and installing a chain link fence along the eastern shoreline. 30-year annual monitoring of sediment conditions in and downstream of the affected area would be performed to detect any movement of the TLM., Estimated Cost: $677,000.00, 3., Sediment Capping and Institutional Controls, - Leave the TLM in place and "cap" it with a physical barrier on top of the sediment. The barrier would be designed to withstand routine flooding and would most likely include a geotextile fabric overlaid by riprap stone. Institutional controls and monitoring similar to Alternative 2 would be included., Estimated Cost: $7,681,000.00, 4., Removal of the TLM and Impacted Sediments, - Physically remove the TLM from the river. This option would include construction of a temporary dam and dewatering of the affected area so that the TLM and sediments could be removed and taken to a licensed off-site facility for disposal. The ecological environment would be restored upon completion., Estimated Cost: $18,529,089.00, Table 2 - Removal Action Alternative Summary Table, Criteria Alternative 1 No Action Alternative 2 Monitoring and Institutional Controls Alternative 3, Sediment Capping and Institutional Controls, Alternative 4 Removal of Impacted Sediment with Off-Site Disposal Overall Protection of Human Health and the Environment, Description: Least Acceptable, Description: Fair to Moderate Acceptability, Description: Moderate to Good Acceptability, Description: Most Acceptable, Compliance with ARARs*, Description: Least Acceptable, Description: Fair to Moderate Acceptability, Description: Moderate to Good Acceptability, Description: Most Acceptable, Short-Term Effectiveness, Description: Fair to Moderate Acceptability, Description: Fair to Moderate Acceptability, Description: Fair to Moderate Acceptability, Description: Least Acceptable, Long-Term Effectiveness and Permanence, Description: Least Acceptable, Description: Fair to Moderate Acceptability, Description: Moderate to Good Acceptability, Description: Most Acceptable, Reduction of Toxicity, Mobility or Volume through Treatment, Description: Least Acceptable, Description: Least Acceptable, Description: Moderate to Good Acceptability, Description: Most Acceptable, Implementability, Description: Most Acceptable, Description: Moderate to Good Acceptability, Description: Fair to Moderate Acceptability, Description: Least Acceptable, Cost, Description: Most Acceptable, Description: Moderate to Good Acceptability, Description: Fair to Moderate Acceptability, Description: Least Acceptable, Overall Summary, Description: Least Acceptable, Description: Fair to Moderate Acceptability, Description: Moderate to Good Acceptability, Description: Most Acceptable, Legend:, Description: Least Acceptable, - least acceptable, Description: Fair to Moderate Acceptability, - fair to moderate acceptability, Description: Moderate to Good Acceptability, - moderate to good acceptability, Description: Most Acceptable, - most acceptable *, Applicable or Relevant and Appropriate Requirements (ARARs), are used to develop remedial action objectives, determine the appropriate extent of site cleanup, and govern implementation and operation of the selected remedial action.Community Engagement - Congaree River
