Problems/Comments
On 5/24/10 an area of petroleum contamination was encountered while excavating approximately 13.6 acres of land for the Temporary Equipment Maintenance Facility (TEMF) parking area. The potentially contaminated area is approximately 20 ft (Length) x 20 ft (Width) x 6 ft (Deep) (approx 89 CY). The contaminant of concern smells like weathered diesel. The PID headspace reading was 34 PPM.
Action Information

|---|---|---|---|
| 5/26/2010 | Site Added to Database | A new site has been added to the database | Mitzi Read |
| 6/3/2010 | Document, Report, or Work plan Review - other | FTW336C Corrective Action Work Plan, June 2010 (ARES) On June 2 the Alaska Department of Environmental Conservation was given a copy of a draft work plan to excavate approximately 20 cubic yards of potentially contaminated soil that had accidentally been transferred to a clean soil stockpile. Minor comment on the plan was given to Fort Wainwright. A revised plan was received June 3 by email that adequately addressed the comments. DEC has no objection to the proposed corrective action. | Debra Caillouet |
| 6/3/2010 | Document, Report, or Work plan Review - other | Technical Memorandum, 336C Luzon Soil Removal Activities, June 2, 2010(Jacobs) On June 2 the Alaska Department of Environmental Conservation was given a copy of a draft work plan to excavate and characterize an area of suspected POL contaminated soil and characterize and properly dispose of the excavated soil. This was revised to two areas of soil based on the field screening in another location after the work plan had been submitted. The source of the first area discovered is unknown and drums labeled JP1 that were thought to have been used for a fighting emplacement may be the source of the second area. Due to the uncertainty in the sources of the contamination, please have the samples analyzed for the Alaska Methods AK101, 102 and 103, and for VOC’s, SVOC’s, RCRA metals and PCBs. | Debra Caillouet |
| 6/7/2010 | Update or Other Action | Notice was received that the accidentally removed contaminated soil was placed into proper containment. | Debra Caillouet |
| 6/7/2010 | Update or Other Action | removed the initial contaminated soil pile from the FTW 336C - TEMF job site located at Luzon and Montgomery Rds. All PID readings were zero at the bottom of the excavation. Potentially contaminated soils were excavated and moved to an ADEC Compliant soil cell behind the DPW Chip Barn. | Debra Caillouet |
| 6/11/2010 | Update or Other Action | Copies of spill reports were recieved. The two areas of concern were reported to PERP on May 21, and June 2, 2010. | Debra Caillouet |
| 6/18/2010 | Update or Other Action | Rec'd preliminary lab confirmation samples from the bottom of the excavations, only exceedance arsenic and it is within background | Debra Caillouet |
| 8/10/2010 | Offsite Soil or Groundwater Disposal Approved | 120 cy analyzed clean transferred to FTW landfill | Debra Caillouet |
| 9/1/2010 | Spill Transferred from Prevention Preparedness and Response Program | Spill transferred by PERP staff Paul Lhotka. Spill no. 10309914102; spill date = 5/21/10; substance = diesel; quantity = unknown. Spill report description: "Spill FWA 10-041. Preliminary Report. During routine construction activities at FTW-336C (TEMF), 'smelly dirt' was excavated. Environmental professionals discerned the odor was weathered diesel. Was found from just below ground level to approximately three feet BGS. Tested with a P.I.D. at approximately 37 ppm. Work in this area was halted pending further investigation." | Mitzi Read |
| 9/1/2010 | Spill Transferred from Prevention Preparedness and Response Program | Spill transferred by PERP staff Paul Lhotka. Spill no. 10309915302; spill date = 6/2/10; substance = diesel; quantity = unknown. Spill report descriptions: "Spill FWA 10-046. Preliminary Report. During routine construction activities at FTW-336C (TEMF), 'smelly dirt' was excavated. Environmental professionals discerned the odor was weathered diesel. Was found from just below ground level at approximately four feet BGS. Tested with a P.I.D. at approximately 75 ppm (cold) and 250 ppm (warmed). Work in this area was halted pending further investigation." "Spill FWA 10-046R1. Preliminary Report. ADDITIONAL COMMENTS: (previous text still applies) this contamination site was found at the base (floor) of a historic 'bunker' constructed out of dirt filled 55 gallon drums; approximately 50 by number. The drums were crushed, shaken out and 'sniffed' with a P.I.D. No contamination was detected. As excavation progressed, a 20 yard side dump truck was filled but failed 'sniff' test prior to being hauled off site. It is suspected that during historic field exercises a 'Yukon Stove' was employed to provide heat to the 'bunker' and suffered leaks. | Mitzi Read |
