CAUSI CESCRIPTION ANO CORRE'.TIVE ACTIONS 27 lTITl [The necessity to provide an energizing signal to solenoid velves discharging to the g jproportional sampler when a te=porary sump pump was installed was overlooked, resultind g lin isolation of the proportional sampler during a greater than 10 gpm sump release.

I g lUpon discovery, release was terminated. Instructions issued to assure proportional l

m l sampler operability when using temporary sump pump. Instructions to be issued to as-l sure proper review or temporary chyges.
