## Narrative

A record rainfall of 6.14"", the largest amount of rain in one day since the construction of the Stamper Mine portal, resulted in the mine's intake lake releasing water. Water traveled down the slope and into a localized area of the mine. We do not believe that this event is ""an unplanned inundation of a mine by a liquid"" and are submitting the 7000-1 at MSHA's direction.
