1.1.1 Incident Category
Time critical removal action.
1.1.2 Site Description
The Jorgensen Forge Outfall Site consists of two outfall pipes, a 24-inch and adjacent 15-inch, buried just south of the current Jorgensen Forge facility’s northern boundary with the adjacent Boeing Plant 2 facility. Both pipes discharged into the Lower Duwamish Watershed (LDW). The LDW was listed on the National Priority List (“NPL”) in September 2001 (CERCLIS No. WA0002329803). In 2002, the Washington Department of Ecology (“Ecology”) added the LDW to the Hazardous Site List under Facility Site identification No. 42927743.
1.1.2.1 Location
The Site is located along the northern boundary of the adjacent Jorgensen and Plant 2 facilities. The street address is 8531 East Marginal Way South, Seattle, Washington, 98108. The approximate location of the east end of the 24-inch PLSD is 47° 31’37.82” North Latitude; 122° 18’13.59” West Longitude.
The Site and surrounding area are primarily industrial. The nearest school (Concord Elementary) is approximately 0.75 miles west-southwest. The closest residences are within a mile are to the west in the South Park neighborhood across the LDW.
1.1.2.2 Description of Threat
Numerous environmental investigations have documented the presence of PCBs in the PLSD pipes which discharge to the LDW. Total PCBs have been detected at concentrations as high as 10,000 mg/kg in a sample collected from the 24-inch PLSD. Multiple samples exceed both the MTCA cleanup level for industrial soil (10 mg/kg) and EPA Regional Screening Levels for industrial soil and the protection of groundwater (0.74 and 0.0088 mg/kg, respectively, for Aroclor 1254).

2.1.1 Narrative
The primary activity on the site at this time is demobilization. Upon the completion of the cleaning and sealing of the 24 and 12-inch clay pipes, the de-watering system was dis-assembled. Samples of the water and the solids were taken to determine proper disposal options. Results are pending. Once the lab data is reviewed, the water and solid waste will be properly disposed.
The ground area around and above where the two west CMP transitional point 12-inch PVC risers was dressed out to established the grade to its original level.

Excavation equipment not needed for the de-mobilization activity was properly decontaminated and removed from the site. The vacuum truck was also decontaminated before departing the site. The solid roll-off containers and water tanks remain onsite pending sampling results. The RP environmental contractor monitored the secondary containment for the solid roll-off and water holding tanks(Baker tanks). Any rain water was transferred to the water holding tanks with portable pumps.
