Tyler was able to confirm that the liquid level on the fuel tank of the conex refrigeration units h owed that 1/16th of the tank remained filled with diesel. The paved area was then power-washed and approximately 100 gallons of wastewater was recovered. Chaz reported that Union Pacific's protocol was to store waste generated from clean-up on site in the hazardous waste storage area until it can be profiled, and then to dispose of it as appropriate.Two 55-gallon drums of liquid waste were generated.Additionally,two batteries were recovered from the crane and from the refrigeration unit on the conex. Both were placed in a poly drum and stored in the on-site hazardous waste storage area to be disposed of. EHD voiced concerns about the liquid released to the storm water system due to rain being in the forecast within the next few hours.Tyler from GrayMar,who had recently assessed the on-site oil- water separator observed the unit again and noted that the liquid level had risen two inches since his assessment on December 111h. He stated that he believed the rise in level could primarily be attributed to recent rain and facility personnel washing the cranes in that area and believed that the unit could still hold several thousand gallons of liquid. However,the exact capacity of the unit could not be determined. Since it could not be confirmed that the oil-water separator had sufficient capacity to hold any Liquid that washed down the storm drain system and the anticipated precipitation, Chaz planned for a portion of the storm drain line to be isolated and flushed using water pressure and the vac truck.The water truck was stationed upstream of the incident, at spot number 518 and the vac truck was stationed at spot 604.The cleanup crew planned to use all the water remaining in the water truck(approximately 300 gallons)to flush this portion of the storm drain system. However, when the water was released and exhausted, it did not travel along the storm drain system. GrayMar reported that it did not appear to flow in either direction. Some puddling was observed within the grates at the location where it was introduced into the drain line, but GrayMar reported that the majority of it"didn't go either left or right".When asked if he observed it get absorbed into the muddy debris within the drain line, he responded that it was either that or it went"somewhere else".The destination of the water could not be determined. Chaz and Tyler discussed the possibility that an obstruction or leak could exist in the line. After updating Lead Sr. Mike Suszycki throughout the night, it was determined that no more could be accomplished for the moment since the crew was out of water and they could not reach anyone who had more knowledge of the storm drain system.Tyler confirmed that the retention pond was lined, so even if the liquid released during the incident was to get washed down the grate line from the rain, it will be possible to recover it. A Notice to Abate was issued advising the facility to take immediate steps to ensure that any hazardous materials released during the incident that entered the storm drain system are cleared from the affected portion of the system.The notice to abate also advised Union Pacific to notify EHD when plans are made for the next phase of clean-up,to provide analytical results and final disposal records for waste generated during clean-up,to dispose of all hazardous waste under appropriate hazardous waste manifesting procedures and that cleanup is to be performed by properly trained individuals. The Notice to Abate was emailed to Elizabeth Wollenberg (elizabeth.wollenberg@up.com) and Chaz Mosley(chaz.mosley@up.com).
