Frequent Questions

Table C25 asks for information about upsets and overtopping since the impoundment was put into service. Many impoundments are decades old. Does EPA want data for incidents after June 1, 1990 or from the date the impoundment was actually put into service?

The instructions read, from the date the impoundment was put into service. However, EPA recognizes that for impoundments that have been in use for many years, or even decades, the knowledgeable parties may have long since left the current owner's employment. Please provide as much information as you can.
