12/16/1993 Site Ranked Using the AHRM Reviewed file in an attempt to rank the site and determined too many unknowns to be able to rank. Site consists of 27 different areas, potentially 27 different contaminated sites. After sampling it should then be determined how many contaminated sites exist. Each site may require a different workplan (to address type of contaminant and conditions). Ranking the site now would imply that it should remain one site. It will, more than likely, become several.

3/2/2000 Update or Other Action Began a RAB January 27, 2000. Second meeting February 18 to complete administrative duties. Staff is working with Jerry Reichlan (Savoonga Corporation attorney) and the community to assist in technical education and technical report interpretation. Jeff Brownlee
3/2/2000 Update or Other Action Review of Draft work plans for the BD/DR and CON/HTRW work to be done in 2000. Main deficiency is the lack of definable DQOs and cleanup criteria for contaminated soil removals. Jeff Brownlee
3/26/2000 Meeting or Teleconference Held Staff attended a RAB meeting to address the FUDS sites at Gambell and NE Cape. Staff held a training the day before for interested community members on technical report interpretation and the specific contaminant issues at the various area at NE Cape. Staff attended and participated in the Share holders meetings at Savoonga and Gambell over the next two days. Jeff Brownlee
4/10/2000 Update or Other Action Staff reviewed a Draft Phase II RI Addendum Report. PCBs were found in fish tissue in the drainage basin over EPA no consumption recommended levels. An RI/FS is planned for next summer. Jeff Brownlee
5/8/2000 Update or Other Action Staff reviewed a draft EE/CA for a large BD/DR and CON/HTRW removal to be started this summer. The BD/DR portion of the work plan was adequate. Staff negotiated to better define the environmental sampling and characterization work with the upcoming RI/FS. The work plan did not adequately address PCB source soil removal and general characterization sampling. Jeff Brownlee
5/8/2000 Update or Other Action Staff reviewed and approved an EE/CA for a large BB/DR and CON/HTRW cleanup to be started this summer. Field work will continue next summer. Jeff Brownlee
5/15/2000 Meeting or Teleconference Held Staff attended a RAB meeting at Savoonga for the Gambell and NE Cape FUDS sites. Discussion involved finishing up the administrative business for the RAB formation and the work division between the BD/DR planned for this summer and the RI/FS planned for next summer. Also discussed the toxicity of PCBs in relation to environmental and human receptors. Jeff Brownlee
8/1/2000 Update or Other Action The COE has agreed to include the White Alice site adjacent to NE Cape in the FUDS program. The Navy was previously thought to have jurisdiction. Jeff Brownlee
9/11/2000 Update or Other Action Staff reviewed a draft Health Consultation report prepared by ATSDR for PCBs and PAHs in fish at NE Cape. The HC recommended that residents of Saint Lawrence Island not consume the fish from the Sugitughneq River (NE Cape) as the PCB levels in three samples were over the EPA recommended consumption levels. The State Division of Epidemiology didn't agree with the level of warning (as approaching a fish advisory) and commented to ATSDR to soften the language, which they did in a subsequent draft final. The HC recommends that more sampling and evaluation be done at the site. Jeff Brownlee
9/15/2000 Update or Other Action A risk assessment performed at Northeast Cape in 1997 was determined by our term contractor and ADEC to be deficient and was not approved. Biological sampling of the drainage occurred in 1997 and 1999. Sampling in 1997 was inadequate to fill the data gaps in the risk assessment and the data quality objectives were not approved for the 1999 sampling. Concern has been expressed in Savoonga about the possible relationship between cancer rates in the community and the FUDS sites, particularly at Northeast Cape. PCBs were discovered in fish (Dolly Varden and Blackish) in Sukitegnek Creek (which drains the site) during the 1999 biological sampling. In August 1999 the ATSDR (Agency for Toxic Substance and Disease Registry - a branch of the Public Health Service) presented in both communities and began a Health Consultation. The Draft report was released in September 2000. ATSDR suggested villagers not consume fish from the Sukitegnek or nearby drainages until a more comprehensive sampling effort is completed. A fish advisory has not been issued. RAB meetings continue to address cancer concerns and RI/FS scoping. Jeff Brownlee
9/18/2000 Update or Other Action (Brownlee/Pingree) Staff contacted Dr. John Middaugh with the State Epidemiology Section to coordinate State opinion on the approach to the ATSDR Health Consultation for Northeast Cape. ATSDR has recommended that residents don't consume the fish from drainage's at or near Northeast Cape because PCBs were found in fish above EPA screening levels. CS and Epidemiology agree that a fish advisory is premature until further data is gathered. CS plans to produce a fact sheet to provide current information for the community and request public input on fishing use in the area. Community members have told ADEC that no fishing takes place in the Sukitughneq River (drains the Northeast Cape facility), but some subsistence activity takes place on the nearby Tapisak River. Jeff Brownlee
11/3/2000 Meeting or Teleconference Held Staff participated in a quarterly RAB meeting. Discussion included field work done at the site this summer. Community members again expressed concern about PCBs in the area fish and requested expanded sampling. The RI/FS workplan review has been postponed until about January so that the community can participate in the TAPP grant process and have an independent review of the document. Jeff Brownlee
3/15/2001 Meeting or Teleconference Held (Brownlee/Pingree) Staff participated in an interactive planning meeting for biological sampling at this site. Participants included the COE and their contractor (Montgomery Watson) and the Agency for Toxic Substance and Disease Registry and CHPPM U.S. Army Center for Human Health Promotion and Preventive Medicine. Pre-scoping for a risk assessment was also part of the agenda. Discussion included the problems inherent with using data on migratory species such as Dolly Varden, salmon and reindeer. These species, however, are the subsistence species utilized by the community. We discussed the specific data gaps that need to be addressed based on existing data. A preliminary conceptual site model was proposed and a tentative schedule to perform a community dietary survey and biological sampling workplan. Jeff Brownlee
5/1/2001 Update or Other Action Staff reviewed a Remedial Investigation workplan for this former Air Force Early Warning Radar Station. Soil and groundwater characterization is planned for this summer. A nearby White Alice Site is also included in the investigation. Two large areas (the Drainage Basin and the Headquarters Area) are contaminated with petroleum and PCBs. Several smaller sites are potentially impacted. The investigation will be performed at the same time as a large Building Demolition/Debris Removal that was started last year. Jeff Brownlee
6/11/2001 Meeting or Teleconference Held Staff participated in a comment resolution meeting for a Phase III investigation workplan. Also participating was Restoration advisory board members from Savoonga and Gambell, T and M Technologies (TAPP Grant contractor), the COE and Montgomery Watson. Work for the investigation will take place this summer. The former Navy White Alice site is now included in the FUDS and will be included in the investigation. One of the main tasks of the investigation is to delineate vertical and horizontal extent of contamination in the drainage basin and headquarters area. Jeff Brownlee
9/26/2001 Meeting or Teleconference Held (Brownlee, Pingree) Staff participated in a scoping meeting on the Conceptual Site Model and the approach for human and ecological risk assessments. The risk assessment will evaluate the subsistence pathway for area fish and berries. The most sensitive mammal species was determined to be the fox. Further sampling of biota and sediment in the impacted drainage basin of the Suki River will help to determine if PCB impacts have occurred to the marine environment. Jeff Brownlee
10/12/2001 Meeting or Teleconference Held Staff participated in a site inspection with the Corps of Engineers. The contractor has been working on a large BD/DR project and a limited CON/HTW removal for the last two summers. Due to larger material volumes than inventoried and shorter field seasons than anticipated the two-year project will now be in its third year next year. Many CON/HTW items remain to be addressed including PCB source soils at the Headquarters area, petroleum contaminated soils and groundwater at several areas and a complete remedial investigation at the former White Alice site. Jeff Brownlee
12/17/2001 Update or Other Action Staff reviewed a draft risk assessment workplan for human health and ecological risk for the site at Northeast Cape. A term contractor also reviewed the workplan. The chemicals of concern are petroleum and PCBs. A drainage basin at the site was impacted with PCBs and petroleum from historical spills. Subsistence pathways are being evaluated for a variety of plants, reindeer and fish. Jeff Brownlee
1/7/2002 Update or Other Action Staff reviewed two UST closure reports from removals performed last field season. Both tanks had soil contamination (DRO) above cleanup levels. Groundwater needs to be characterized in the area of both tanks. Both USTs were in the Headquarters area at this former Early Warning Radar Station. A phase III remedial investigation is planned for the summer of 2002 and will include groundwater and soil characterization throughout the Headquarters area. Jeff Brownlee
1/14/2002 Meeting or Teleconference Held Staff participated in a comment resolution meeting for a risk assessment workplan for PCBs impacting resident fish and sediment in a drainage basin near the Northeast Cape facility. The PCBs were believed to have commingled with past diesel spills at former early warning radar site. The ADEC is evaluating additional data collected during 2001 to see if contaminants have migrated to the marine environment. Specific subsistence user ingestion rates are also being further evaluated with island residents and published rates. Jeff Brownlee
1/17/2002 Site Ranked Using the AHRM Changed Observed Environmental Impacts value from 5 to 0 because entries exist for Surface Water Environments and Environmental/Recreation Area values. No Longer Assigned
3/11/2002 Meeting or Teleconference Held Staff participated in a Restoration Advisory Board meeting for Northeast Cape and Gambell. Also participating in the meeting was the TAPP grant manager, Alaska Community Action on Toxins, ATSDR, the COE and their contractor. Dr. Bob Johnson with ATSDR presented information on the Reindeer Health Consultation. PAHs were found in low concentrations in reindeer tissue, but at levels well below benchmarks that would be considered a health risk at conservative subsistence use values. It was discussed that the reindeer range over the entire island and contaminant correlation with a particular site would be difficult. The Phase III investigation performed in Gambell was discussed. Jeff Brownlee
7/10/2002 Meeting or Teleconference Held Staff participated in a Restoration Advisory Board meeting in Savoonga for the Northeast Cape and Gambell FUDS. An approximately $10 million contract for work at the Northeast Cape site will be awarded to a contractor this week. The work will include BD/DR of the remaining buildings including the lower White Alice site facility and some HTW work. Work on a Phase III investigation may continue this fall at Northeast Cape if the contracting can be completed before the end of the season. Jeff Brownlee
11/15/2002 Meeting or Teleconference Held Staff participated in a comment resolution meeting for a Phase III investigation and risk assessment for Northeast Cape. The risk assessment had a few deficiencies one of which was making the assumption that shallow groundwater is not a reasonably expected future drinking water source. This conclusion is not supported by the known hydrology and possible future land use by the local residents, so the risk assessment has to be redone to evaluate and include this pathway. There was a question on whether to include background PCB in biota in the risk calculations or subtract it out. The army and EPA risk assessment guidance’s subtract background concentrations out of the risk calculations, however Alaska State guidance specifies that for organics background data is included unless the background concentrations are higher than those measured at the site. Background sample amounts are weak for media other than soil. The validity of the statistics for these background assumptions are questionable because of the small sample set. There were also several problems with editorial and quality of tabulated data in the risk assessment. Summary tables were not utilized as frequently as they should have been, so the assessment was difficult to review. Jeff Brownlee
1/10/2003 Cleanup Plan Approved Staff reviewed workplans for a Building Demolition/Debris Removal (BD/DR) and limited Containerized Hazardous or Toxic Waste (Con-HTW) removal. The workplans detail dismantling and removing from the island the remaining buildings and debris from the former early warning radar and communications site and the nearby White Alice Communication Site. Limited areas of petroleum contamination in soil and miscellaneous drums will be containerized and removed. PCB contaminated concrete over action levels will also be containerized and removed. The DEC is negotiating to have any PCB contamination over action levels in soil also removed during this effort. The majority of the debris will have to be treated as asbestos containing material as the waste streams are too mixed to efficiently separate. Currently the plan calls for all the hazardous waste and solid waste to be shipped to a disposal facility in Oregon, however there is ongoing discussion with the landowner about constructing an on-site monofil for the inert solid waste. Jeff Brownlee
1/29/2003 Update or Other Action Staff coordinated with Health and Social Services Epidemiology Section on responding to a report written by Alaska Community on Toxins (ACAT). The ACAT report, Contaminants in Wildlife and People of St. Lawrence Island, Alaska: A Report to the Communities of Savoonga and Gambell, was released in October 2002. The report claimed that St. Lawrence Islander people had a PCB concentration in blood higher than the norm. The report also claimed a causal effect between PCBs found in community members’ blood and military activity on the island, specifically Northeast Cape. After review of the data Epidemiology concluded that the PCB blood concentration in the people of Saint Lawrence is comparable to other Alaska communities dependant on a subsistence lifestyle. The review also concluded that the PCB blood concentrations detected are likely a result of global contamination through the food chain, although both Epidemiology and the DEC support continued cleanup of the military sites on the island. Jeff Brownlee
2/7/2003 Update or Other Action Staff reviewed a Phase III Remedial Investigation Report for Northeast Cape. About a dozen sites at this former early warning radar and communication station have groundwater and soil contamination. The principle contaminants of concern are Diesel Range Organics, Residual Range Organics and PCBs. Also present are metals (arsenic, chromium, lead) and some low level PAHs in both soil and groundwater. The chromium and arsenic are likely background, but may be anthropogenic at a couple sites. We are still evaluating background data and may require more sampling. Estimated amount of soil impacted above Method 2 Table B levels at the facility are in excess of 100,000 cubic yards. Jeff Brownlee
2/14/2003 Meeting or Teleconference Held Staff participated in comment resolution meeting for work at Northeast Cape planned for this summer and the 2004 field season. The work involves Building Demolition/Debris Removal and some Containerized Hazardous Waste removal. The primary issue that developed during the review was changing the Corps of Engineers anticipated cleanup level in concrete and soil from 25 mg/kg to one. A risk assessment has been performed for PCBs at Northeast Cape, but the risk calculations were not carried through to specific cleanup levels. Much of the building material contains mixed asbestos waste that would not be cost effective to separate into different waste streams, so the majority of debris (approximately 12,000 cubic yards) will be considered asbestos waste and containerized for off-island disposal. Jeff Brownlee
4/10/2003 Meeting or Teleconference Held Staff participated in a Restoration Advisory Board meeting for the two Formerly Used Defense Sites on Saint Lawrence Island. Upcoming projects for the summer were discussed. A Native American Lands Environmental Mitigation Program (NALEMP) project is scheduled in Gambell this summer. Portions of two military dump sites will be excavated and the debris removed off island. The work is being done because new housing is planned for these areas. A large Building Demolition/Debris Removal is planned for Northeast Cape. The project is scheduled for two years and includes some Containerized Hazardous Waste removal. The Alaska Community Action on Toxins (ACAT) report on PCB in blood serum of the Saint Lawrence Island people was discussed. There was some disagreement on interpreting the State Epidemiology review of the report, which indicated there were statistical and procedural problems with the report. Unfortunately there was no representative from Epidemiology to help clarify the issues. Dr. David Carpenter (State University of New York) was hired by ACAT to conduct the study and produce the report. Dr. Carpenter and ACAT participated in the RAB meeting. Jeff Brownlee
6/19/2003 Update or Other Action CS staff reviewed a final Technical Memorandum for the determination of inorganic background levels at Northeast Cape, Saint Lawrence Island. A conservative technique using outlier tests and probability plots were used to evaluate all the site data for inorganic chemicals in soil (separated into tundra and gravel types) surface water, groundwater and sediment. If there were two populations noted in the plots the lower concentration population was assumed to be the background set. After outliers were eliminated the remaining data was calculated for the 95% background upper tolerance limit (BUTL). The derived 95% BUTL was conservative for most chemicals and within common ranges found in Alaska. Exceptions were lead and nickel in sediment, which were above NOAA (National Oceanic & Atmospheric Administration) “thresholds effects level”. Jeff Brownlee
8/5/2003 Meeting or Teleconference Held CS staff attended a Restoration Advisory Board meeting at Gambell for FUDS on Saint Lawrence Island. The meeting discussed an update of the NALEMP (Native American Lands Environmental Mitigation Program) project that is going on at Gambell and an update of the cleanup progress at Northeast Cape. The NALEMP project is addressing debris under the footprint of some future HUD housing. So far about 700 empty drums and miscellaneous metal debris have been removed from the scoped work area. Only small amounts of POL contamination has been noted usually associated with oil filters. The COE contractor at Northeast Cape is making rapid progress with taking down the buildings. It appears that they will be finished with the contracted scope of work this season instead of needing the projected two seasons. If the COE decides to exercise optional task work they will need to pay the contractor to keep the camp and equipment on site for the winter or pay for another mobilization. The TAPP (Technical Assistance Program Plan) grant contract expires the end of September. There was some contention at the meeting over the COE suggesting that the current TAPP grant coordinator may have a conflict of interest because he is doing other work on the island with ACAT (Alaska Community Action on Toxins), although he is not being paid for that work. The contract has to go out for bid according to TAPP contract regulation, but of course the community and ACAT want to maintain continuity with the current provider. There was also some emotional concern expressed over the perceived high cancer incidence on the island. Jeff Brownlee
12/4/2003 Update or Other Action CS staff reviewed the previous environmental investigative work at Northeast Cape on Saint Lawrence Island for completeness. There has been stakeholder concern (chiefly Alaska Community Action on Toxins - ACAT) that several sites at the Cape have not been adequately characterized. Several data gaps were identified, but none that would not allow development of the feasibility study. The previous three investigation phases have been done with State approved workplans and reports according to industry standards. Jeff Brownlee

There has been stakeholder concern (chiefly Alaska Community Action on Toxins - ACAT) that several sites at the Cape have not been adequately characterized. Several data gaps were identified, but none that would not allow development of the feasibility study. The previous three investigation phases have been done with State approved workplans and reports according to industry standards. Jeff Brownlee
12/23/2003 Update or Other Action CS staff and a term contractor reviewed and commented on a draft final risk assessment (human heath and ecological) for contamination at Northeast Cape, a formerly used defense site on Saint Lawrence Island. The assessment shows several sites exceed acceptable risk levels for both human health and ecological receptors. The majority of sites exceed target hazard index and cancer risk levels based on cumulative risk. We are asking for summary tables that clearly separate the current risks from potential future risks assuming a future residential scenario. A large risk driver at the sites is contaminated groundwater, which is not currently used as a drinking water source. The draft risk assessment does include calculation of proposed method 4 cleanup levels, which would aid in completing the feasibility study and establishing alternative cleanup levels. Staff is working with the COE to incorporate our comments into a final document for department approval. Jeff Brownlee
12/23/2003 Update or Other Action CS staff reviewed and comment on a draft final risk assessment (human heath and ecological) for contamination at Northeast Cape on Saint Lawrence Island. The assessment was also reviewed by our risk assessor and a term contractor. Several sites are over risk departure numbers for both human health and ecological risk. The majority of sites over target hazard index and cancer risk levels are based on cumulative numbers. We are asking for summary tables separating the current exposure scenarios from potential future receptors settings. A large part of the risk drivers at the sites is from contaminated groundwater, which has to be evaluated by regulation, but is unlikely to be a future exposure pathway. The assessment does not carry through to risk based cleanup number which we need to have for the feasibility study and development of potential cleanup levels. Staff is working with the COE to incorporate our comments into a final document for department approval. Jeff Brownlee
1/22/2004 Meeting or Teleconference Held CS staff participated in a Restoration Advisory Board meeting for the FUDS on Saint Lawrence Island. Also participating were approximately 20 RAB members, Alaska Community Action on Toxins (ACAT), the RAB Technical Assistance Program (TAP) coordinator, the attorney for the two Saint Lawrence Island Native Corporations and a reporter for KALM radio in Nome. A summary report was presented of the building demolition/debris removal work done last summer at Northeast Cape. All of the buildings at the White Alice Site and the main Headquarters area have been removed. The COE is intending to award optional contracts for 2005 to remove some remaining items including the tram system to the former radar facility on a nearby mountain. CS staff summarized the characterization effort to date by site and discussed data gaps. The COE has decided to do one more investigation to address these data gaps. The investigation is planned for this summer and will include several groundwater monitoring wells. The Feasibility Study that was done for Gambell was discussed. Three sites remain that require a remedial action. Two sites need some additional hydrogeology information to support the proposed Method Two ingestion cleanup level. The Gambell NALEMP (Native American Lands Environmental Mitigation Program) report was also discussed. Approximately 50-tons of metallic debris from two former landfills were removed. The debris was mixed empty drums, Marston matting, engine parts, cable, piping and miscellaneous scrap. About 3-tons of incidental contaminated soil was containerized in super sacks and disposed off island with the metal debris. Confirmation sampling showed excavation limit results below Method Two cleanup levels. Jeff Brownlee
1/29/2004 Meeting or Teleconference Held CS staff participated in a comment resolution meeting for a risk assessment at Northeast Cape on Saint Lawrence Island. Also participating were members of the Restoration Advisory Board, Alaska Community Action on Toxins, The Technical Assistance Program coordinator for the RAB, The Army Center for Health Promotion and Preventive Medicine (CHPPM), the Native Corporations attorney, and the COE and their contractor. The risk assessment is in the draft final stage. The COE has incorporated all the draft comment changes and has included groundwater as an exposure pathway. The COE agreed to include summary tables that will allow readers unfamiliar with risk assessments to easily compare the site risks with the different exposure scenarios (for example permanent resident vs. subsistence user) (Brownlee, Smith). CS staff reviewed a preliminary workplan for investigation work at the Northeast Cape FUDS on Saint Lawrence Island. The investigation work will take place this summer and be the final investigation before the feasibility study (FS). Several monitoring wells will be installed as well as sampling of soil, sediment, groundwater and surface water. The work should provide information to fill data gaps and delineate contamination to better prepare volume estimates in the FS (Brownlee). Jeff Brownlee
3/31/2004 Meeting or Teleconference Held Staff participated in a Restoration Advisory Board meeting for the FUDS on Saint Lawrence Island. The Feasibility Study for Gambell was discussed as well as the upcoming Proposed Plan. Dr. Ron Scrudato (New York State University) is the Technical Assistant Program coordinator for the RAB. Dr. Scrudato gave a briefing on the findings of a grant study he is doing in coordination with Alaska Community Action on Toxins (ACAT). The grant is funded by the National Institute of Environmental Health Sciences and focuses on human health and environmental contamination on Saint Lawrence Island. Sampling of sediment, air and plant tissue for PCBs is showing point source contribution at Northeast Cape and also assumed global contribution at both Northeast Cape and Gambell. By analyzing individual congeners the vapor pressure and likely transport mode and relative time of deposition (sediment) can be determined. The RAB also discussed the upcoming remedial investigation at Northeast Cape this summer Jeff Brownlee
6/24/2004 Site Characterization Workplan Approved Staff reviewed a work plan for a remedial investigation at the Northeast Cape FUDS on Saint Lawrence Island. The site is in the fourth phase of the remedial investigation. Several data gaps have been identified that when filled would aid in the development of the feasibility study. Several groundwater monitoring wells will be installed, developed and sampled. Several areas of known soil and sediment contamination will be further characterized as well as more sampling for soil and sediment background and total organic carbon. Ground water will also be tested for natural attenuation parameters Jeff Brownlee
7/13/2004 Meeting or Teleconference Held Staff participated in a comment resolution meeting for a Phase IV investigation at the Northeast Cape FUDS on Saint Lawrence Island. Participating in the meeting was the Corps of Engineers as the responsible party, the COE consultant, Pam Miller with Alaska Community Action on Toxics, Dr. Ron Scrudato as the communities TAPP (Technical Assistant for Public Participation) grant coordinator, Morgan Apataki from Gambell and the DEC. The investigation is designed to address data gaps identified by the cleanup team over the past several document reviews.

The COE said they would review the document schedule and get back to the members Jeff Brownlee
9/7/2006 Update or Other Action Contaminated Sites staff reviewed and commented on a draft Feasibility Study for the Northeast Cape Formerly Used Defense Site on Saint Lawrence Island. No further action is proposed for 17 out of 30 sites at the facility. The study presents several remedial alternatives for the remaining sites including containment such as capping, insitu such as chemical oxidation and ex-situ treatments such as incineration or excavation and off site disposal. Limited actions such as natural attenuation, long-tem monitoring and institutional controls are also evaluated. The study does not attempt to choose specific alternatives, but evaluates the balancing criteria including cost for each individual site. Remedial alternatives will be chosen during development of the Proposed Plan. It is probable that many of the sites will have chosen remedies that are a combination of the presented alternatives for example excavation and off-site disposal combined with institutional controls and long-term monitoring Jeff Brownlee
