Summary
This earth dam has a height of 34 feet and a storage capacity of 5700 acre-feet. Located in the St. Louis District with a significant hazard potential, this impoundment is regulated by the Illinois Department of Natural Resources and inspected by the Mine Safety and Health Administration.
Despite its critical function in providing water supply, the condition assessment of the Slurry Impoundment is currently not available, raising concerns about its long-term safety and reliability. The last inspection date was in January 2013, highlighting the need for regular monitoring and maintenance. With its proximity to the city of ATTLIA and the potential risks associated with a significant hazard potential, ensuring the structural integrity and emergency preparedness of this impoundment is crucial for water resource and climate enthusiasts in the region.
As water resource and climate enthusiasts evaluate the risks and benefits of structures like the Slurry Impoundment, it is essential to consider the potential environmental impacts and emergency response capabilities. With no designated Emergency Action Plan (EAP) or risk assessment information available, there is a need for proactive measures to enhance the safety and resilience of this water supply facility. Collaboration between regulatory agencies, private owners, and local stakeholders will be essential in addressing any potential vulnerabilities and ensuring the long-term sustainability of the Slurry Impoundment in Saline, Illinois.

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.
