The docket for USAs (#5455) has also been very active, with comments due by June 27, 2000. The definition of USAs will have a ripple effect on the pipeline industry. For example, USAs are included in the currently proposed definition of High Consequence Areas. Of particular interest are the comments submitted by the American Water Works Association (AWWA), whose membership supplies water to 80% of the people in the nation. They want the DOT to "designate all drinking water supplies as USAs". This would increase the number of USAs. The AWWA also proposes that Source Water Assessment Plans (SWAPs) be used to designate the area requiring protection, not just the Wellhead Protection Area. This would increase the amount of area that would be considered a USA.
