Spill Transferred from Prevention Preparedness and Response Program |
Site transferred by PERP staff Toivo Luick. Spill no. 04399915602; PERP file no. 425.02.012; Susbtance spilled = Diesel; Quantity = ~4,000 gallons.
This was a spill from a 20,000-gallon tank at an old school tank farm (no longer used). Someone unknown left a valve open (it is suspected that this occurred while that person was stealing old fuel from the unused tank). The tank was no where near full at the time of the release. A response effort was made, but no soil was excavated (mostly booming, skimming, and sorbents were used), due to the fact that the area was flooded at the time. |

Document, Report, or Work plan Review - other |
Reviewed the 2008 Point Lay Site Asessment Report for several Point Lay sites including this one. 22 test pits were excavated in the vicinity of the school and surface water samples were collected from 5 surface water bodies surrounding the site. 33 soil samples were collected from test pits and were analyzed for DRO, RRO, GRO, and BTEX. DRO was detected up to 3,790 mg/kg and benzene up to 0.209 in a sample from test pit 2 at 2.5 feet bgs. The highest concentrations of contaminants were found east of the school at the former location of two large ASTs from which a 4,000-gallon fuel release had been documented in 2004. DRO was also detected above the screening level at test pits located in topographic low spots; TP 14 had DRO at 589 mg/kg a 4 feet bgs and TP 20 had DRO at 497 mg/kg at 2.5 feet bgs. Surface water samples collected from tundra ponds around the school did not contain contaminants above Alaska Water Quality Standards. Sheen was not observed during shovel sheen tests at any of the testing locations. |

Date of receipt of document entitled Point Lay Kali School, Second Phase Site Characterization, Work Plan Addendum. Work will begin in April to further delineate two areas of contamination found during last year's investigation with cleanup levels above Maximum Allowable Concentrations. There was a third area that was above these levels but that area was fairly well delineated and not a good candidate for a removal or other active remediation due to the presence of buildings and a large AST. Four additional borings will be advanced around each of the areas to be further investigated, MW-01 and PM-3. Two samples will be collected from each of these borings and analyzed for GRO/DRO/RRO and VOCs with 10 percent PAHs. |

Reviewed the document titled Point Lay Kali School Second Phase Site Characterization Report Addendum – Final, dated February 2, 2016. Sixteen soil samples were collected from eight soil borings advanced at this site (two from each boring). The soil borings were positioned specifically to delineate contamination at two specific sampling locations (MW-01 and PM-3) that were identified in 2014. Soil Borings SB-01 through SB-04 were advanced in the vicinity of Sample MW-01, and Soil Borings SB-05 through SB-08 were advanced in the vicinity of Sample PM-3. Analytical results revealed that contamination is delineated at these two areas.
In a letter sent February 2016, ADEC requested a work plan by April 1, 2016 for additional groundwater sampling. |

HISTORICAL REVIEW PART I: Three source areas exist at this site; the 1991 release at the transfer operation area, the school day tank, and the 2004 release from the old school tanks.
A significant fuel release was discovered during a facility inspection at the Cully Corporation tank farm in June of 1991. The release was discovered shortly after the spring thaw, and it was initially estimated that between 3,000 and 6,000 gallons had been spilled just northwest of the tank farm area, directly behind the school. Fuel records were nonexistent at the time, and as such the amount of fuel spilled is considered a loose estimation. The release occurred because of poor fuel handling practices during transfer operations to smaller vessels during the winter months.
Initial cleanup actions consisted of absorbing free floating product with sorbents. In August of 1992, most of what could be soaked up by sorbents had been, and the only visual evidence of contamination remaining were residual sheens and stressed vegetation. The spill impacted an approximate 3-acre tundra area to the south of the tank farm, as shown above in the 1991 spill map.
Soil samples collected from the impacted tundra contained over 1,000 milligrams per kilogram (mg/kg) DRO. At the time, impacts were not suspected from the gravel tank farm area; however, a soil sample collected from the school day tank, north of the tank farm area, exhibited a concentration of DRO over 6,000 mg/kg DRO.
Following the 1991 release, the North Slope Borough (NSB) entered into a Compliance Order by Consent (COBC) with ADEC in March of 1993. The COBC called for remediation of the gravel and tundra by September 30, 1994 (later modified to 1995) for two existing sites; the NSB Point Lay Former Tank Farm/Point Lay Power Plant site (currently listed as cleanup complete with institutional controls) and this site, the NSB Point Lay Kali School Site (currently listed as active).
The Cully School tank farm was decommissioned in 1995. The tank farm consisted of six storage tanks with a combined holding capacity of 210,000 gallons. All six tanks were removed and transported to the municipal landfill. Corrective action began in July and concluded in September 1995. Contaminated gravels from the tank farm and sewage lagoon berm (interconnected to the tank farm) were excavated and transferred to stockpile cells located just outside the landfill and were remediated using a gravel washing technique. The entire sewage lagoon berm (except for the southern and eastern edges), along with the tank farm pad and access road were removed up to the school fuel tank. All contaminated gravels were removed to a maximum depth of 4-inches above the tundra. A total of 2,163 cubic yards of impacted material was excavated and treated.
Confirmation soil samples were collected from the Cully School tank farm and sewage lagoon area. A total of 59 soil samples were collected from established 15-feet grids. Six (6) of those samples were analyzed for DRO at an onsite laboratory. Additionally, one 1 sample was sent offsite for laboratory analysis for quality assurance purposes (and comparison). Analytical results generally concluded that the main tank farm pad area was remediated, with only one sample result (at 3,221 mg/kg DRO) exceeding the ADEC cleanup level. A sample collected from the tank farm access road, near the school day tank, exhibited levels of DRO at 30,627 mg/kg, which exceeds ADEC Method Two maximum allowable concentrations (MACs). Samples collected from the western berm of the sewage lagoon were not analyzed, however a strong petroleum odor was noted.

HISTORICAL REVIEW PART II: It should be noted that the one sample sent for offsite analysis did not have an odor, nor elevated field screening readings from the photoionization detector (PID). As such, accuracy of the onsite testing is questionable. Also, analytical samples submitted from the main tank farm area were not submitted from the highest PID field screening locations, which again, tends to bias the data.
Following the gravel removal effort at the tank farm, limited tundra bioremediation was completed. This remediation effort primarily consisted of raking the tundra once per week to promote natural degradation. Following this limited effort, stressed vegetation remained visible at the northwest corner of the tank farm pad where it meets the access road (about 1,200 square feet), near the school day tank. Several other smaller areas of stressed vegetation were noted along the western edge of the berm where there had been separate diesel spill in 1994.
Further environmental work was not completed at this site until August 2003. A soil sample was collected in August 2003 from one of the pilings being driven near the school day tank to support construction of a new school addition. It is not clear whether the sample was collected from the piling hole, from the drill cuttings, or from a separate test pit near the piling; however, it was noted that the sample was from between 2 and 4 feet below ground surface. Samples results were as follows: DRO at 3,580 mg/kg, benzene at 0.215 mg/kg, toluene at 2.30 mg/kg, ethylbenzene at 5.42 mg/kg, and xylenes at 23.69 mg/kg.
A pungent petroleum odor was noted during the piling drilling activities, as well petroleum sheening was noted on the surface water downstream from the drilling area. It is not clear if school addition is currently placed over the former day tank.
On June 4, 2004 a release of roughly 4,000 gallons was reported at this site. The source of the release was from two interconnected old school tanks used for heating oil (capacity of tanks was 20,000-gallons). Reportedly, a trespasser was stealing fuel from the old tanks and failed to shut the valve off after fueling. Based on ADEC documents, the old school tanks were located on the northeast corner of Tract 2B, at the intersection of Ugruk Avenue and Tuttanniagvik Street. Spill response actions included restricting free product movement with booms, recovering fuel with sorbents, skimmers, pumps, and a vacuum truck, and removal of fuel laden snow and ice. Excavation was not performed.
An assessment of the NSB Point Lay Kali School Site was performed in September 2008. A total of 22 test pits were excavated in the vicinity of the school, and surface water samples were collected from 5 surface water bodies surrounding the site. Thirty-three (33) soil samples were collected from the test pits, most of which were collected from between 1 and 2.5 feet below ground surface. Samples exhibiting the highest concentrations of DRO and benzene (up to 3,790 mg/kg and 0.993 mg/kg, respectively) were collected from the old school tanks from which the 2004 fuel release occurred. Surface water sample results from tundra ponds around the school did not contain contaminants above Alaska Water Quality Standards (AWQS). Sheen was not observed during shovel sheen tests at any of the testing locations.
Additional site characterization activities were completed in 2014 and 2015. Activities conducted in 2014 included soil, sediment, surface water, and groundwater sampling. Sixty-six (66) soil borings were advanced, 10 of which were completed as groundwater monitoring wells. Soil and water samples were collected from all the borings, wells, and surface water bodies as appropriate. Also, 10 locations were sampled for co-located surface soil and surface water. In 2015, sixteen soil samples were collected from eight soil borings advanced at this site (two from each boring). The soil borings were positioned specifically to delineate contamination at two specific sampling locations (MW-01 and PM-3) that were identified in 2014. Soil Borings SB-01 through SB-04 were advanced in the vicinity of Sample MW-01, and Soil Borings SB-05 through SB-08 were advanced in the vicinity of Sample PM-3. Analytical results revealed that contamination is delineated at these two areas.
Additional groundwater monitoring was completed in August 2016. Eight (8) of the 10 monitoring wells were located and sampled. Wells MW-SO-F2 and MW-SO-F8 were not found and may have been destroyed by winter recreational vehicles and/or snowmobiles. Samples collected from MW-01, MW-02, MW-05, MW-SO-L4, and MW-SO-Q3 exhibited compounds in excess of Table C groundwater cleanup levels and/or the Alaska Water Quality Standards.
