Summary
1, also known as Holding Pond #1, is a private water supply structure located in Mt. Sterling, Pennsylvania. This earth dam stands at a height of 90 feet and stretches 1100 feet in length, with a storage capacity of 153 acre-feet. While not state-regulated, this low-hazard structure serves a primary purpose of water supply, with associated purposes including tailings storage.
Managed by the Mine Safety and Health Administration, Slurry Pond No. 1 has not undergone recent condition assessments, inspection dates, or emergency preparedness evaluations. Despite its low hazard potential, the structure's risk assessment, management measures, and inundation maps remain unspecified. With no state jurisdiction or regulatory agency oversight, this pond serves as a vital yet under-monitored component of the water resource infrastructure in Greene County, Pennsylvania.
For water resource and climate enthusiasts, Slurry Pond No. 1 offers a glimpse into the complex network of private water supply structures that play a crucial role in supporting various industrial processes. Its proximity to the Huntington District underscores the intersection of mining operations and environmental stewardship, raising questions about the long-term sustainability and resilience of such structures in the face of evolving climate challenges. As efforts to improve dam safety and emergency preparedness continue to gain importance, the case of Slurry Pond No. 1 serves as a reminder of the need for comprehensive monitoring and risk assessment protocols in safeguarding our water resources for future generations.

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.
