|General Site Description:||The site is a railroad siding in Rowena, Wasco County, near the Rowena exit of Interstate Highway 84. River Road is just north of the spill site. Residential properties lie between River Road and the Columbia River, which is 800 feet north of the site.|
Oregon DEQ is overseeing investigation and cleanup of a diesel spill that occurred at a rail siding in Rowena on February 15, 2004. The spill was discovered by Union Pacific Railroad (UPRR) when a crew member noticed that one of three idling locomotives on a parked westbound train had shut off. The crew found the engine compartment sump full of diesel fuel. The cause of the malfunction was determined to be a cracked fuel filter.
|Contamination Information:||(1/9/06 BPS/VCP) Diesel, BTEX|
|Manner and Time of Release:||Diesel spill from a parked, idling locomotive.|
|Hazardous Substances/Waste Types:||petroleum, BTEX|
|Status of Investigative or Remedial Action:||
(1/9/06 RPS/VCP) Spill response activities during February and March 2004 included flushing the affected area with water and pumping diesel into vacuum trucks. Booms and sorbents were used to contain the fuel during this phase of cleanup. Following this phase, UPRR installed two groundwater monitoring wells just north of the siding track in May 2004.
By July 2005, nine wells had been installed. These include five along the north side of the siding track and two south of the spill area, which verified that there were no upgradient contamination sources. Some free-phase diesel was found in the three wells closest to the spill. As a result, UPRR installed two wells on the north side of River Road, to monitor groundwater quality near the residential properties between River Road and the Columbia River. No contamination was found in either of these wells during the two sampling rounds conducted to date (July and October 2005).
To get a better sense of the extent of contamination, UPRR installed 51 soil borings in July 2005. About 12 of these were placed along the north side of River Road. The rest were between the siding track and the south side of River Road. Presence of petroleum was determined based on inspection of the soil samples in the field, by sight and smell, and by lab analysis for petroleum. Free-phase petroleum was observed over an area between the tracks and the south side of the road. This area extends about 90 fest east-west by about 25 feet north-south. In addition, detectable concentrations were found in some of the soil samples north of River Road. The highest level of diesel found north of the road was 1,420 mg/kg.
UPRR has proposed conducting soil treatment in place (that is, without excavating the contaminated soil) to reduce petroleum levels. This work is scheduled to take place during spring 2006.
(3/20/06 KJR/SAS) Site proposed for listing on CRL and Inventory. No comments received. Site listed on CRL and Inventory.
(July 9, 2007, Bob Schwarz) Contamination exceeded risk screening levels only marginally following the completion of emergency response activities. However, UPRR installed an air sparge system to reduce contaminant concentrations in groundwater so that the risk of migration of these contaminants would also be reduced. This system, which included three air sparge wells installed at the locations shown in Figure 2. The system operated for about six months, from July 2006 until January 2007.
(Aug. 6, 2007, Bob Schwarz) DEQ issued an NFA for this site on July 31, 2007.
