Actions taken to respond to and correct the emergency situation or condition <br /> • At approximately 7:20 am, a release of water was observed at the refinery located at AGADR. An <br /> estimated 350 gallons of water exited the refinery and flowed approximately 100 feet to the south, off of <br /> containment. The fresh water feed to the wet scrubber was turned on; however the sump pumps were not <br /> running. Consequently, water draining from the scrubber overtopped the sumps and drained out of the <br /> refinery door. <br /> • At approximately 7:25 personnel noticed the release and immediately turned the sump pumps on, <br /> stopping the release. <br /> • The majority of the water released from the refinery collected in two parking ditches located in front of <br /> AGADR(see photo 1). <br /> • A submersible pump was used to pump the pooled water from the parking ditches back into AGADR(see <br /> photo 2). After ponded water was pumped back into AGADR, a backhoe was used to collect the impacted <br /> soil (see photo 3 and 4). The soil was removed using an `over-excavation' approach. Depth of recovery <br /> was approximately six to twelve inches. <br /> 1 <br />
