Summary

The dam, with a height of 13 feet and a storage capacity of 250 acre-feet, serves as a crucial resource for the surrounding area. Despite its low hazard potential, the dam has not been assessed for its condition, posing some uncertainty about its long-term sustainability.

The Mine Safety and Health Administration oversees the regulatory and inspection aspects of "E" Pond Treatment, ensuring compliance with safety standards. However, there is limited information available on the dam's structural integrity and maintenance history, raising questions about its overall reliability. With the last inspection conducted in 2004, there is a need for updated assessments to address any potential risks and implement necessary risk management measures to safeguard the water supply.

As water resource and climate enthusiasts, it is essential to advocate for regular monitoring and maintenance of infrastructure like "E" Pond Treatment to protect against unforeseen emergencies and ensure the continued availability of clean water. By promoting transparency and accountability in dam management, we can contribute to the sustainable use of water resources and mitigate potential risks associated with aging infrastructure.

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.
