Summary
The tailings dam, completed in 1996, stands at 35 feet high and serves as a crucial structure for containing waste materials from mining operations. With a storage capacity of 9,000 acre-feet and a surface area of 265 acres, the dam plays a vital role in managing water resources in the region.
Situated on Payne Creek, the dam has a controlled spillway with a width of 64 feet to manage maximum discharges of up to 30 cubic feet per second. The hazard potential of the dam is rated as significant, highlighting the importance of regular inspections and risk assessments. Despite being in operation for over two decades, the condition assessment of the dam is listed as "Not Rated," indicating a need for further evaluation to ensure its safety and effectiveness in the face of potential climate-related challenges.
Overall, Pc10 Payne Creek Mine represents a critical infrastructure for water management and environmental protection in the area. With its earth core, stone foundation, and soil structure, the dam plays a crucial role in safeguarding water resources and mitigating potential risks associated with mining activities. As climate change continues to impact water availability and quality, the proper maintenance and monitoring of this dam are essential to ensure the safety and resilience of the surrounding communities and ecosystems.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
