Update or Other Action |
Comments on Shop/Camp area Draft Final Report submitted to CH2MHill.
Report Title - not sure if we should call this a final report since more work needs to be performed onsite. Cleanup Action Interim Report or makes sense. I can close out individual sites if you desire; still have questions concerning the confirmational samples and groundwater and do not see closure to at this pointfor this area. My comments by section:
Section One
page 1-2 para 2 last sentence, "A thin layer of perched water..."
Was this layer continuous or discontinuous?
page1-2, para 3 - any noted surfacewater drainages on site?
page 1-6, table 1-1 - RRO regulatory level is 8,300 not 9,700. Cleanup level is capped at the most stringent Inhalation, Ingestion or Migration to Groundwater level. In this case it is capped at Ingestion. Note this will affect confirmation sample ANC01SL14 in terms of RRO clean closure.
page1-7, para 1 - I concur with your conclusions for methylene chloride. Common laboratory occurrence
page 1-7, para 3 - also concur with your arsenic conclusions. Very common to have levels of background arsenic similar to yours in Alaska
Section Two
page 2-1, para 1 - Method Two, Migration to Groundwater cleanup goals are appropriate for this site, is this your requested cleanup level?
Table 2-1 - Soil cleanup goal for RRO is capped at most stringent ingestion level of 8,300
Section Three
page 3-1, para 1 - the stockpile as built is limited to two years in situ with a 20-mil liner. What are your future intentions for the soil?
page 3-1, para 4 - What are the intentions/possible timelines for excavation of remaining soil under the structures?
Groundwater Sampling and Conclusions
One single sample and duplicate does not seem to be thorough enough for the complete site. The report states multiple times that a layer of "perched water" was seen throughout the site. If groundwater is extensive, then this would justify a few more samples from the different areas.
The description of groundwater and how the sample was collected is very limited. What did the groundwater look like? Sheens? Any floating product as in splotches of motor oil, hydraulic fluid? Any clearer photographs? For your groundwater sampling, did you sample straight out of a test pit after it was mucked up by the shovel? Your actual GW levels may be lower and not need a 10X rule decision. Collection of water samples from the bottom of test pits is not recommended. Installation of a simple 2" PVC well may suffice.
Mention is made of surfacewater runoff, but no sampling occurred in surfacewater drainages. How do you explain sample ANC01SL18 which shows high benzene next to the diversion creek? When onsite evidence shows the potential for a surfacewater/groundwater interface, generally we request that surfacewater be sampled for Total Aqueous Hydrocarbons and Total Aromatic Hydrocarbons (TAqH and TAH) to ensure this pathway is not affected by contamination.
Application of the 10x rule may be workable; however the process is more rigorous than your conclusion. More sitewide water sampling is needed than a single sample. (It could be that only a small area is contaminated and the surrounding areas are uncontaminated...)
Confirmational Sampling
Excavation sidewalls did not appear to be sampled. Also, confirmational samples need to be collected one every 100 square feet of ground surface. (Petroluem Cleanup Guidance) We can approve smaller numbers of confirmational samples within reason prior to initiating onsite work. More sampling will be needed to confirm excavation work is done.
Laboratory Records
I assume all records will be in the final of this report. |

Site Characterization Report Approved |
Recieved Site Characterization report from Montauk Environmental evaluating outlying areas of operation out of the camp. Contamination found to be mostly petroleum hydrocarbons. These sites are distict and separate from camp shop and buildings. Montauk proposed Method Three Cleanup level. Project manager required additional organic carbon sampling, further evaluation of subsurface water onsite to evaluate wheather it is an aquifer or not. GW appears to be perched, not a viable aquifer. SW is the drinking water source for the camp and adjacent areas. Also required additional site specific sampling for potential contaminants of concern that may have been missed. |

| 3/11/2004 |
Cleanup Level(s) Approved |
Site removed from VCP to use Method Three Cleanup levels. Method Three ACL approved for Sortyard and Outlying areas with RRO at 8,300 ppm, DRO at 6,700 ppm, GRO at 1,400 ppm, Benzene at 0.118 ppm, Toluene 67.7 ppm, Ethylbenzene 92.7 ppm and Total Xylenes at 1,320 ppm. |

Update or Other Action |
Phone call with Cliff Elsmann at Montauk. Finished recent fieldwork and 1500 cubic yards of screened material, 30 samples from sortyard were taken for confirmation. Ttwo excavations at sort circle and ast area were performed. Noted makeup of ground was different than expected. Mostly bedrock, but found highly compressed riprap and cobbles. Sortyard was fill, wtih about 12 feet of dirt.
Put in about 80-odd test holes around the entire area. Did confirmational samples, one spot had to reexcavate, next step will be the treatment and outlying sites which may be the 2nd week of June. Enzyme Tech and L&C will be proposing on remediation through bioaugmentation. |

Meeting or Teleconference Held |
Met with Bill DeAtri, Jim Erickson of Aluutiq Corporation and their consultant regarding this season's fieldwork at the Sortyard area. The Sortyard is to be used by Whitestone Logging and Alutiqq is requesting a separate closure of this area prior to Whitestone moving onsite. Review of this season's site actions show Sortyard to be in good shape with the exception of some diethylene glycol above cleanup level in the sump area. Will NFRAP site with a note that the sump will need further evaluation once current operations are closed down.
Both Jim Erickson and Bill DeAtri reaffirmed Aluutiq's committment to continue the cleanup of this facility in phases and will send out an official letter stating their intentions for the site.
Work at this site is progressing steadily. |

Update or Other Action |
Telecon with Cliff Elsmannn at Mauntauk. Told him we could explore the possibility of conditionally closing the site if the bio cells could be shown to be the 95 UCL based on systematic random sampling. Soil would have to be managed in place and would have to reach most conservative cleanup levels if proposed to be moved or used for other purposes. |

Cleanup Plan Approved |
On November 20, 2008, the Alaska Department of Environmental Conservation (ADEC) received the Request for Department Authorization to Dispose Post-Treatment Soil for the Danger Bay Log Camp facility submitted on behalf of the Afognak Native Corporation by Cliff Elsmann (Montauk E/E). On December 16, 2008, ADEC received the Addendum to 18 Nov. '08 Contam. Soil Transportation Request, also submitted by Montauk. Additional information was submitted via e-mail by Cliff Elsmann on December 28th and December 30th.
Based upon the information presented in the above referenced documents, the request to land spread the approximately 1,800 cubic yards of petroleum impacted soils is approved. In addition, the proposal to utilize the East Cell for the purpose of remediating the additional contaminated soil generated from the upcoming Old Shop cleanup (March 14, 2008 POL-Contaminated Soil Treatment Plan, approved on March 26, 2008) is also approved provided that the excavation and remediation activities follow the approved March plan (except for the revised location for remediation cell construction).

Document, Report, or Work plan Review - other |
Reviewed the Cleanup Report, Former Ben A. Thomas Inc. Old Shop Building, Danger Bay, dated October 2009, from Montauk Environmental Engineering for Don Fritz. Approximately 1,730 cubic yards of soil was excavated within and north of the former Old Shop area, west of the Old Shop area, and in two vehicle storage areas north and northeast of the former Old Shop area. DRO soil contamination remains in the south side wall of the former Old Shop Building excavation at approximately 1 ½ feet below ground surface, and Benzene soil contamination remains in the west side wall of the former Old Shop Building excavation at approximately 4 to 4 ½ feet below ground surface. Arsenic and Chromium was detected above the soil cleanup levels in all the laboratory samples and the presence of these concentrations is believed to be naturally occurring. The presence of Mercury above the soil cleanup levels is not known. No known Mercury containing compounds were utilized on the site, other than the thought that the World War II era saw mill might be the contributing factor. The excavated soils were stockpiled north of the site for remediation using ammonium nitrate. |

Letter to Afognak Native Corporation regarding information presented in Cleanup Report Former Ben A. Thomas Inc. Old Shop Building. Excavation Area A (Former Footprint of the Old Shop Building); the majority of the impacted soils have been excavated and moved to the treatment cells. One sample under the shop wall exceeded the migration to groundwater cleanup level for DRO at 299 mg/kg and one sample from the west wall exceeded the migration to groundwater cleanup level for benzene at 0.0254 mg/kg at approximately 4 to 4 ½ feet below ground surface. Based on this soil sample data, these residual contaminant concentrations are acceptable; however, should additional contamination be detected when the remaining building is demolished, additional assessment and cleanup may be required. Based on the information presented within the report, cleanup efforts at Areas B, C, and D are considered complete. No further cleanup work is required in Areas B, C, and D at this time. ADEC has requested a workplan for closure sampling of a 1730 cubic yard contaminated soil stockpile.
