Summary

6, located in Corbin, Kentucky, is a privately owned earth dam with a primary purpose of containing tailings. Standing at a height of 40 feet and stretching 1150 feet in length, this dam has a storage capacity of 760 acre-feet. Despite being categorized as low hazard potential, the condition assessment for Module No. 6 is currently listed as not available, indicating a need for further evaluation and monitoring to ensure its structural integrity and safety.

Managed by the Mine Safety and Health Administration, Module No. 6 does not fall under state jurisdiction for regulation, permitting, inspection, or enforcement. The dam has not been modified in recent years, and there is no available information on emergency action plans, risk assessments, or inundation maps. With limited data on its condition and risk management measures, there is a call for increased attention to the maintenance and monitoring of Module No. 6 to mitigate any potential hazards and ensure the safety of the surrounding community and water resources.

For water resource and climate enthusiasts, Module No. 6 presents an interesting case study in the management of earth dams for industrial purposes. With a focus on tailings containment, this dam serves a crucial role in the area's mining operations. However, the lack of detailed information on its current condition and risk management strategies highlights the importance of proactive monitoring and maintenance practices to safeguard against any potential failures or environmental impacts. As such, further research and assessment of Module No. 6 could provide valuable insights into the intersection of water resource management, infrastructure safety, and environmental sustainability.

Condition Assessment

Satisfactory
No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.

Hazard Potential Classification

High
Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
