Downstream Hazard Potential definition

Downstream Hazard Potential means the category of a dam that indicates its potential adverse impact on the downstream areas should the dam or its appurtenant structures fail or be mis-operated. The Downstream Hazard Potential reflects probable loss of human life or adverse impacts on economic, environmental, or lifeline interests, or other concerns, such as water quality degradation. The Downstream Hazard may be one of three categories: High Hazard Potential, Significant Hazard Potential, and Low Hazard Potential. DEP, ERP Applicant’s Handbook: Vol. I, s. 2.0(a)(37) (proposed 2023).

Downstream Hazard Potential means the classification of a dam that indicates its potential adverse impact to the surrounding and downstream areas should the dam or its appurtenant structures fail or be mis-operated. The downstream hazard potential reflects probable loss of human life or impacts on economic, environmental, or lifeline interests, or other concerns, such as water quality degradation. The downstream hazard potential does not indicate the current condition of the dam or the risk of it failing.

Examples of Downstream Hazard Potential in a sentence

  • A Downstream Hazard Potential shall be determined for each dam based on probable loss of human life or adverse impacts on economic, environmental, and lifeline interests, and other concerns, such as water quality degradation, should the dam or appurtenant structures fail (e.g., breach) or are mis-operated (e.g., unscheduled release).

  • Lastly, for dams in series, each upstream dam shall have a Downstream Hazard Potential equal to or greater than the next downstream dam.

  • Also, the Downstream Hazard Potential may change over time (typically, it will increase as the downstream area is developed).

  • The key analysis assumptions, methods, and results are documented in a Downstream Hazard Potential Classification Study report and the report is reviewed and approved by the BIA SOD Officer before the hazard potential classification of a dam can be changed.

  • Importantly, the Downstream Hazard Potential does not reflect the current safety, structural integrity, or flood routing capacity of a dam and its appurtenant structures.

  • Prior to initiating a Downstream Hazard Potential Classification Study, the BIA SOD Officer must approve the hazard classification reevaluation, the proposed methods to reevaluate the hazard classification, and the individual(s) who will be performing the study.

  • If at any time the Regional SOD Officer believes that the downstream hazard potential classification of a particular BIA dam may have changed, the Regional SOD Officer may request that a Downstream Hazard Potential Classification Study be performed.

  • The four criteria require: 1) providing dam system information, 2) establishing a Downstream Hazard Potential, 3) developing an Emergency Action Plan for a High Hazard Potential or Significant Hazard Potential dam, and 4) submitting a Condition Assessment Report for a High Hazard Potential or Significant Hazard Potential dam.

  • Special Flood Hazard Area means an area that FEMA’s current flood maps indicate has at least a one percent (1%) chance of a flood equal to or exceeding the base flood elevation (a 100-year flood) in any given year.

  • Airport hazard means any structure, object of natural growth, or use of land which obstructs the airspace required for the flight of aircraft in landing or taking off at an airport, or is otherwise hazardous to such landing or taking off of aircraft.

  • Imminent hazard means the existence of a condition that presents a substantial likelihood that death, serious illness, severe personal injury, or a substantial endangerment to health, property, or the environment may occur before the reasonably foreseeable completion date of a formal proceeding begun to lessen the risk of that death, illness, injury, or endangerment.
