(Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). Reviewed a draft workplan: "Environmental Site Assessments for Community Enterprise Development of Alaska, August, 1993", prepared by Montgomery Watson and received by ADEC/WDO 9/3/93. Insufficient information was available for adequate plan review and approval. Phase I or II Site Assessments needed for most of the AC Store sites. |

Spill Transferred from Prevention Preparedness and Response Program |
Spill transferred by PPRP staff Megan Kohler. Spill no. 10279932401; spill date = 11/20/10; substance = arctic grade diesel; quantity = ~30 gallons; description: a fuel pump switch accidentally engaged causing fuel to be released from a vent pipe into the courtyard south of the furnace room.
Additional releases that have occurred on this property include: spill nos. 04279929701, 05279901201, and 08279900801. |

Site Reopened |
Site reopened to address releases of arctic grade diesel #1 that occurred between 2004 and 2010 from the furnace and generator day tanks and were under the management of the DEC Prevention Preparedness and Response Program. In August 2015, a site characterization report was submitted that confirmed contaminants remained in soil and groundwater above DEC cleanup levels.
The cleanup complete determination was issued for the site on April 2, 2003 encompassed the contamination described in a 1993 environmental site assessment that was conducted at 33 Alaska Commercial Company (AC) stores across Alaska. Three areas of gasoline and arctic grade diesel #1 contamination were confirmed above DEC cleanup levels at the AC store in Emmonak (aka AC Value Center). Sources included three above ground storage tanks (ASTs), a pump house, two generators, a generator building, three heating oil ASTs, and five drums. In 1997 and 1998 approximately 1,000 cubic yards of contaminated soil was removed and treated using in-situ landfarming techniques. |

Document, Report, or Work plan Review - other |
Site Characterization AC Value Center report reviewed on this date. The report covers testing and sampling done in 2013 in response to diesel spills that occurred in the area of the former furnace room and generator shed between 2004 and 2010. Gasoline Range Organics (GRO), Residual Range Organics (RRO), Diesel Range Organics (DRO), Benzene, Toluene, Ethylbenzene, and total Xylenes were tested for in both soil and groundwater. GRO and DRO were detected in subsurface soil above ADEC cleanup levels for direct contact, while GRO, DRO, RRO, and Benzene were above ADEC cleanup levels for Groundwater . Due to soil permeability and high water table, remediation through soil removal may cause structural damage to several buildings, roads and utilities. |

Document, Report, or Work plan Review - other |
Remediation Activity Work Plan AC Value Center was received on this date. Based on review of the work plan, a meeting between ADEC, the RP, and consultant has been scheduled for May 4, 2017. |
Lisa Griswold |

Meeting or Teleconference Held |
ADEC held a meeting with RP and consultant to discuss reviewed revised work plan. Items discussed included: 1) If the goal for the site was a cleanup complete with institutional controls, or if the goal was to establish an alternative cleanup level in an attempt to reach a cleanup complete. It was indicated that both were being considered. ADEC gave your consultant the Technical Memorandum for Determining the Fraction of Organic Carbon for Methods Three and Four as establishing an alternative cleanup level requires the information in the memorandum, but is not currently in the work plan. (This memo can be found at: http://dec.alaska.gov/spar/csp/guidance_forms/docs/DeterminingtheFractionofOrganicCarbon2017.pdf) 2)If the “site cap” was being considered as a permanent institutional control. The work plan indicated that this is the case. As such, ADEC stated that the site cap, as described in the work plan, could not be considered a permanent institutional control. In order to be protective of soil and ground water, a site cap is to be impermeable and requires a maintenance plan. ADEC recommended that the site cap be reviewed as to how best accomplish the requirements as a control. 3)The availability of the ADEC Data Quality Objective Memorandum (found at: http://dec.alaska.gov/spar/csp/guidance_forms/docs/LabDataandQAPolicyTechMemoMarch20173.pdf). This recently-updated memorandum is an excellent source of guidance as it applies to this work plan including: a)The need for clearly defined goals in the work plan. b)If the location of borings was to assess contaminant attenuation since 2015. Our discussions verified that this was the goal, and it was suggested that the planned borings more closely align with the 2015 boreholes in order to insure a better comparison. c)A clarification in the work plan as to which “ADEC approved lab” the samples would be sent to. It was indicated that the lab would be SGS. d)A clarification in the work plan regarding the statement that groundwater parameters would be “read” and whether that meant “stabilize”. e)A clarification in the work plan that referenced waste water being treated as hazardous waste. It was recommended that the wording be reviewed as the water was not likely going to be considered hazardous waste or require treatment and disposal as hazardous waste.f)Lastly it was discussed that more characterization should be considered to the north of the current contaminant boundary. G13-03 (the northernmost sampling point) contained contaminants above ADEC cleanup levels, and therefore the extent of contamination has yet to be defined. A revised work plan is requested by June 5, 2017, and should be sent to the new project manager: Amy Rodman. |

Site Characterization Report Approved |
ADEC reviewed and approved the “Emmonak AC Store 2018 Monitoring Trip Results” (Report) for the Alaska Commercial Co. Store - Emmonak site in Emmonak, AK dated May 2019. The report was submitted to ADEC via email on May 16, 2019 by Golder Associates, Inc. (Golder). Field activities were conducted on October 10 & 11, 2018 and generally consisted of advancing four soil borings, field-screening soil, soil sample collection for laboratory analysis, and sampling five groundwater monitoring wells. A work plan is due June 30 to address groundwater contamination and surface soil contamination at the site. |

Update or Other Action |
Chris Valentine for Golder Associates called. He states that he is putting together a work plan for the site that will likely be implemented in 2021 (instead of 2020) due to Covid-19 and travel restrictions. ADEC has no objections to this schedule. |

Site Characterization Workplan Approved |
The "Work Plan for Additional Soil Sampling at the AC Center Property" dated June 22, 2021 is approved. Approval letter sent via email on this date. The work plan describes field screening and collecting four soil samples from the area of soils exceeding cleanup levels in 2018. The soil samples will be analyzed for gasoline range organics (GRO), volatile organic carbons (VOCs), diesel range organics (DRO), residual range organics (RRO), and polycyclic aromatic hydrocarbons (PAHs). Groundwater samples will be collected from G13-03, G13-02, G13-01, G13-12, and G13-10 and will be analyzed for GRO, VOCs, DRO, RRO, and PAHs. |
