2.1.1 Narrative
OSC Liverman assumed lead OSC from Greg Weigel on 10 June 2015.
2.1.2 Response Actions to Date
Refer to prior POLREPs for a discussion of actions prior to this reporting period.
- RP contractors on-site in support of 24-hour operations include: GeoEngineers, Inc.; Able Cleanup Technologies; Environmental West; Big Sky Industrial; and Eclipse.
- Continued monitoring of boom deployed in the Sanpoil River for the presence of petroleum contamination; no visible product or sheen has been observed in the river or on absorbent materials.
- Equipment on-site includes: 2 vacuum trucks; 2 21,000 gal Baker tanks and 1 8,000 gal tank near the release; 23 21,000 gal Baker tanks at the nearby WSDOT facility; 2 10,000 poly tanks at the WSDOT facility; 1 activated carbon filter treatment system at the WSDOT facility; 3 air compressors for sparging effluent tanks; and other support equipment such as generators, light plants, contractor vehicles, etc.
- LNAPL skimming pumps in recovery wells RW-9 and RW-10 are operated continuously and surged every hour to skim LNAPL from the wells. Skimming is performed until visible LNAPL is not observed in the discharge line. The deep pump in well RW-10 runs continuously to maintain a cone of depression on the groundwaterr table. A skimming pump in RW-8 is activated approximately once every half hour and surged until LNAPL is no lomnger obsewrved in the discharge line.
- Continued surface water, groundwater, and waste disposal, and effluent sampling. Data for rurface water quality samples were all non-detect.
- Continued traffic control with one lane of Highway 21 closed through the site.
- EPA and Colville Tribes reviewed draft Interim Petroleum Remediation Work Plan developed by GeoEngineers for Able Cleanup Technologies.

2.2.1 Anticipated Activities
- Continue recovery of liquid and vapor phase product from RW-3, RW-5, RW-8, RW-9, and RW-10.
- Collect groundwater, surface water, and effluent samples.
- Continue to monitor river and absorbent materials for discharge to river.
2.2.1.1 Planned Response Activities
Continue groundwater extraction and treatment and soil vapor extraction activities, and sampling and monitoring activities. Continue to review 'Interim Petroleum Remediation Work Plan.'
2.2.1.2 Next Steps
Continue to evaluate/improve the interim petroleum removal activities (i.e., improve the efficiency of extraction and treatment systems), and continue to review/finalize the 'Interim Petroleum Remediation Work Plan.'
2.2.2 Issues
The final disposition of treated groundwater is not yet resolved (i.e., collected and treated groundwater is being stored temporarily on-site pending it's final disposition (i.e., disposal at a nearby POTW or land application). Ongoing discussion with Washington State Department of Ecology and Kettle Falls POTW are ongoing.
