Under the National Incident Management System (NIMS), the Unified Command structure is used in stormwater emergencies when:
Answer: Multiple agencies with different legal authorities are involved
Unified Command is activated when multiple agencies with different jurisdictions or legal authorities must coordinate a joint response to the same incident.
What is the primary function of secondary containment systems at industrial facilities in a stormwater emergency context?
Answer: To prevent spilled materials from reaching stormwater conveyances
Secondary containment systems (berms, dikes, vaults) are designed to capture spills at the source and prevent them from entering stormwater drainage systems.
A stormwater system experiences a dam failure during a 100-year storm event. Which emergency action has the highest priority for protecting downstream populations?
Answer: Issuing downstream evacuation warnings
Life safety is always the highest priority in dam failure events, making immediate downstream evacuation warnings the first critical action.
Which type of stormwater emergency plan specifically addresses the actions a municipality must take to protect public health when combined sewer overflows (CSOs) occur during heavy rain?
Answer: Long-Term Control Plan (LTCP)
Long-Term Control Plans (LTCPs) are required by EPA for municipalities with combined sewer systems and address emergency management of CSOs to protect public health.
During a flash flood emergency, a stormwater manager should use which communication protocol to ensure field crews receive consistent instructions?
Answer: Plain language standardized under NIMS/ICS protocols
NIMS requires the use of plain language (clear text) during emergency communications to prevent miscommunication across agencies and disciplines.
A facility's Spill Prevention, Control, and Countermeasure (SPCC) plan must be amended within how many days after a spill that reaches navigable waters?
Answer: 60 days
Under 40 CFR Part 112, SPCC plans must be reviewed and amended within 60 days following a spill that reaches navigable waters or adjoining shorelines.
Which tool is most useful for pre-event emergency planning to identify which areas in a watershed will be inundated first during a major storm event?
Answer: Stormwater GIS mapping with flood inundation layers
GIS-based flood inundation mapping overlays watershed topography, drainage infrastructure, and storm modeling to predict which areas flood first during major events.
