On 4/9/1996, Environmental Management, Inc. submitted a "Manokotak School Spill Release Investigation and Corrective Action Report" dated March 1996. The Report documented contaminated soils near the Manokotak School related to the spill that occurred in December 1994. The report also discovered additional contaminated soils next to the 1994 spill location related to past spills at the nearby tank farm. On 1/9/1997, ADEC project manager, Shah Alam, mailed a letter to Mr. Henry Versnick, Maintenance Director of Southwest Region Schools, asking him to submit a work plan to remediate contaminated soils, and to submit information as to the final disposition of the stockpile. ADEC approved a disposal plan for the stockpile next to the school in October 1995. Analytical samples taken in 1996 showed DRO up to 17,500 ppm in one area, and ranging from 18 ppm to 7,100 ppm. |

Site Characterization Report Approved |
Report entitled "Final Site Assessment Report, Manokotak School, Manokotak, Alaska" by E&E, dated January 1999 was received by ADEC. Results indicate that contamination of soil and groundwater by DRO above ADEC cleanup standards does exist. However, the number of samples was limited and the extent and volume of contaminated soils may not be entirely assessed. |

Update or Other Action |
Analytical results from the E&E Final Report were as follows: DRO was detected at 720 mg/kg at 9.5 feet bgs, and 3,000 mg/kg at 24.5 feet bgs. GRO was not detected. BTEX results were low-level, however cross contamination was suspected, due to to BTEX being detected in the trip blank sample. Detection limits for benzene were above ADEC Method 2 cleanup levels. Groundwater sample results show DRO (280 mg/L) and GRO (1.6 mg/L) present, along with BTEX consituents (0.089 mg/L total). PAH's were not detected above ADEC cleanup levels. |

Document, Report, or Work plan Review - other |
DEC received a Property Assessment and Cleanup Plan for the former Manokotak School. September 21 - 24, 2010, SLR conducted a site visit in Manokotak. SLR observed the Former Manokotak School site, which includes the abandoned BIA School building, two former teacher housing buildings, and an equipment storage/old generator building. In additon to the buildings, three ASTs were present at the site: One 500-gallon AST on the east end of the generator shed building, one 750-gallon AST within the former school generator area, and one 8,000-gallon AST within the former AST tank farm area. A total of 98 field screening soil samples were collected from 21 test borings and three test pits that were excavated across the Site. Hydrocarbon odors were noted at the Site near areas of recently disturbed soil. Areas of stained soil and gravel were also noted at the Site, particularly near ASTs. During this field effort, ninety-seven field screening soil samples were collected from multiple depth intervals. Eight analytical samples including one duplicate were also collected and analyzed for GRO, DRO, RRO, BTEX, lead, and PAHs. The maximum detected concentration of DRO was 39,600 mg/kg and the max. concentration for GRO was 637 mg/kg and ethylbenzene was 8.11 mg/kg. Two drinking water samples were collected from the "Old Village" drinking water system. The results from the wells had a detection of trichlorofluoromethane, but below drinking water cleanup levels. SLR estimates approximately 1,000 cubic yards of contaminated soil in the top 5 feet (1994 Spill Area, Former Tank Farm Area, Former Generator Area, and other isolated spots) that should be excavated and treated.SLR also recommends that the solid waste be removed, asbestos abatement and sampling be conducted, buildings be demolished (if not needed), and the contaminated soil in the area be excavated to five feet bgs at a minimum. |

Institutional Control Update |
On this date, a Notice of Environmental Contamination (NEC) was signed by Southwest Region School District (SWRSD) and the City of Manokotak and was sent to the Recorder's Office. The institutional controls (ICs) outlined in the NEC are similar to the previous ICs: 1.) The Landowner shall restrict access to the contaminated areas of the site, by erecting a fence and placing ADEC approved signage notifying the public of the presence of hazardous contamination; 2.) Installation of groundwater wells on the property of the Former Manokotak School requires ADEC approval; 3.) For excavation or demolition work in areas where surface and sub-surface soil contamination is located a work plan must be submitted to ADEC for managing the contaminated material that may be encountered. ADEC approval is required prior to moving any soil or groundwater off-site (see 18 AAC 75.325(i)); 4.) Movement or use of contaminated material in a manner that results in a violation of 18 AAC 70 water quality standards is prohibited; 5.) In the event that the property is transferred prior to the cleanup being completed and ADEC approving removal of the institutional controls, the new owner must agree with and establish procedures to implement the required institutional and engineering controls, and the Notice of Environmental Contamination shall be updated and recorded in the State Recorder’s Office.
