Summary
The dam has a surface area of 35 acres and serves the Pegs Run river/stream, with a drainage area of 0.2 square miles.
Despite being regulated by the Pennsylvania Department of Environmental Protection and subject to state inspections and enforcement, Pegs Run Slurry Impoundment has been assessed as having a low hazard potential with a fair condition. The last inspection was conducted in July 2017, with an inspection frequency of 5 years. While the dam poses a low risk, there are currently no Emergency Action Plans (EAP) prepared, and it is unclear if the existing EAP meets guidelines or if risk assessment and management measures have been established.
Overall, Pegs Run Slurry Impoundment serves as a significant water resource infrastructure in the region, providing storage for slurry material with minimal environmental impact. However, the lack of comprehensive emergency preparedness measures raises concerns about the facility's ability to respond effectively in case of emergencies or natural disasters. For water resource and climate enthusiasts, monitoring the ongoing maintenance and risk assessment of Pegs Run Slurry Impoundment is crucial in ensuring the safety and integrity of this important structure.

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.
