Summary
7, located in Maysville, KY, along the Ohio River, is a crucial water resource structure owned by a public utility in Ohio. This ash pond serves as a repository for tailings, with a dam height of 38.6 feet and a storage capacity of 1155 acre-feet. Despite its significant hazard potential, the condition assessment of the dam is currently rated as poor, indicating a need for maintenance and improvements to ensure its long-term safety and functionality. The last inspection in June 2018 highlighted the need for regular monitoring and updates to mitigate risks associated with this structure.
Managed by the Department of Natural Resources in Ohio, Jm Stuart Station Ash Pond No. 7 falls under state jurisdiction, with permitting, inspection, and enforcement processes in place to regulate its operations. The dam, primarily constructed of earth materials, spans 3150 feet and is designed to contain tailings in an area with a drainage area of 0.06 square miles. The structure's location near the Ohio River underscores the importance of maintaining its integrity to prevent any potential environmental hazards or water contamination in the surrounding area.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the proper management of structures like Jm Stuart Station Ash Pond No. 7 to safeguard water quality and ecosystem health. By staying informed about the condition and regulatory oversight of such facilities, we can contribute to the sustainable management of water resources and promote resilience in the face of climate challenges. Collaborative efforts with state agencies and stakeholders are vital to ensuring the safety and effectiveness of water infrastructure like this ash pond for the benefit of both the environment and local communities.

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.
