Description: The inner emergency management area is defined as the area in which the public water supply utility would have little or no time to respond to a direct discharge of contamination, other than to close the intake. Communication between emergency responders and the water utility will be essential for effective response action in this area. This is the area where a spill is most problematic because it is likely that a public water supply system would not have time to fill their reservoirs or adjust treatment technologies to address the spill. This area is based on an 8 hour TOT upstream of the intake based on high flow conditions. Additionally, contaminant threats, subwatersheds and areas of concern are considered and reflected in the delineated boundary of the Priority A area. The purpose of this area is similar to the Inner Emergency Response Area delineated for the SWA, but uses a detailed TOT study as part of the delineation process for the big three.
