Summary
Managed by BBC&M ENGINEERING, this dam stands at a height of 22 feet and spans 1515 feet, with a storage capacity of 54.4 acre-feet. Situated on the KOKOSING RIVER, this structure is regulated and inspected by the DEPARTMENT OF NATURAL RESOURCES, ensuring compliance with state permitting and enforcement requirements.
Despite being classified as having a significant hazard potential, Neutralized Water Impoundment 2 is assessed to be in fair condition as of the last inspection in November 2019. With a surface area of 1.8 acres and no normal storage capacity, this dam has a maximum discharge rate of 15 cubic feet per second. While the structure has not been modified in recent years, it is subject to regular inspections every five years to ensure its continued safety and integrity.
As a vital component in managing tailings and water resources in the area, Neutralized Water Impoundment 2 plays a crucial role in maintaining environmental safety and regulatory compliance. With its strategic location and design, this dam serves as a key asset in safeguarding the surrounding community and the KOKOSING RIVER watershed from potential risks and hazards associated with tailings containment.

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.
