Problems/Comments

Site was used by the Navy from 1939 to 1975 as a disposal area - primarily metals debris. A debris removal was done by the COE in 1985. Possible disturbance of contaminated soils occurred during this removal. PCBs, cadmium, lead and chromium were detected in soil at levels above regulatory levels in a 1993 USCG investigation. Two investigations in 1999 detected higher levels of PCB in two areas (987 mg/kg and 103,000 mg/kg). An investigation and removal action will continue during the 2000 field season. Volume of soil estimated to be above regulatory criteria for PCBs is unknown. A risk assessment was perfomed in 2003. An intermittent drainage flows through the gulch and it appears some PCB transport has occurred with sediment movement. EPA ID# AK9690330742. In RCRA file system. Also listed in CERCLIS file system under USDOT CG Kodiak Sanitary Landfill USCG Support Center. Hazardous waste activities: generator 1, transporter, disposer, burns HW fuel in burner. Attempts to enter Consent Order with Coast Guard have been unsuccessful. Last staff assigned were Roberts, Schwenne, Patrick-Riley, Seagren, and Brownlee. Remedial action was implemented in 2004 and continues through 2006. Soil concentrations of PCB over 10 mg/kg are being removed and disposed off island. A 2-foot plus vegetated soil cap is being placed over the footprint of historic disturbance in the gulch. The site will have institutional controls and land use restrictions.

Action Information

Action Date	Action	Description	DEC Staff
11/9/1995	Site Added to Database	PCBs, cadmium, lead and chromium.	Kent Patrick-Riley
11/28/1995	Site Ranked Using the AHRM	Site ranked. Score = 54.	Kent Patrick-Riley
2/22/2000	Meeting or Teleconference Held	Staff attended an interactive planning/comment resolution meeting with the COE, EPA, TSCA, and Coast Guard in Seattle. Discussion centered on cleanup levels, land use and institutional controls. Consensus was the site needed more characterization and the next step should be a feasibility study.	Jeff Brownlee
3/17/2000	Site Ranked Using the AHRM	Reranked. Score = 165.	Jeff Brownlee
7/17/2000	Update or Other Action	Reviewed IRA work plan. Further PCB characterization work to be performed with approximately 95 surface samples and borings. A ecological assessment of the drainage to check for aquatic organisms will be done and a survey of terrestrial animals that may use the drainage.	Jeff Brownlee
11/24/2000	Update or Other Action	ADEC and EPA jointly sent a letter to the COE detailing concerns about the approach to the remedial investigation and feasibility study. A few of the EPA and ADEC comments on the RI work plans have not been adequately addressed, a baseline risk assessment needs to completed, the feasibility study needs to be "non presumptive" and the remedy should be permanent, with no maintenance nor ICs.	Jeff Brownlee
12/20/2000	Site Number Identifier Changed	Workplan changed from 09 to X9 to reflect correct oversight program.	Former Staff
3/2/2001	Update or Other Action	Staff reviewed a Remedial Investigation/Feasibility Study for Drury Gulch near the Coast Guard Base on Kodiak Island. The Gulch was used a metals debris dump in the 1960s and 1970s by the Navy and Army. A debris cleanup in the late 1970s appears to have spread PCB contaminated soil over a large area (approximately 6 acres). Investigations show that about 8,000 cubic yards of soil are impacted with PCBs over 10 mg/kg. The RI/FS did not include historical data from three previous investigations, so the ADEC is requesting a rewrite of the draft to include all available data. The Feasibility Study was limited to three options, the preferred one being excavation and offsite disposal of soil with concentrations over 10 mg/kg and placing a two-foot cap over the site.	Jeff Brownlee
3/21/2001	Meeting or Teleconference Held	Staff participated in a comment resolution meeting for a Draft RI/FS for Drury Gulch. This former metals dump has several thousand cubic yards of PCB impacted soil over 10 mg/kg. Attendees included the COE and their contractor, the U.S. Coast Guard and the EPA. Several concerns were addressed including the COE not using all available historical data for the Feasibility Study and that too few remedial alternatives were evaluated. Terrestrial ecological pathways were not adequately evaluated. The COE will issue a Draft Final for the cleanup teams review and concurrence prior to beginning work on the remedial design workplan.	Jeff Brownlee
5/4/2001	Meeting or Teleconference Held	Staff participated in a Kodiak Island Borough assembly meeting and public open house in Kodiak. The Corps of Engineers and their contractor, Jacobs engineering also attended. Three potential new sites were inspected based on community input. Overall interest seemed light, which has been normal in Kodiak.	Jeff Brownlee
12/5/2001	Meeting or Teleconference Held	Staff attended a comment resolution and scoping meeting for the Drury Gulch site. The Corps of Engineers and their contractor (Jacobs), the EPA and their contractor (Tetra Tech), the Coast Guard and the ADEC attended the meeting at the Coast Guard offices in Seattle. The comment resolution was for the RI/FS document. Comments on the document were minimal, however a decision was not made on the preferred remedy. To finalize the RI/FS the COE will need to produce a long-term monitoring plan, institutional control plan, perform a round of well sampling and complete the requested ecological screening work. The schedule for the proposed plan and record of decision was discussed as well as the possibility of doing an interim removal action this summer to take advantage of available funding.	Jeff Brownlee
4/29/2002	Site Characterization Workplan Approved	Staff reviewed a workplan for an additional investigation at this former Navy disposal area on Kodiak Island. Drury Gulch has PCB contamination in soils over an approximately six-acre area and some impacts to sediment in a small drainage through the gulch. During previous investigations debris has been encountered during borings. The debris is inferred to be left from the original waste deposited in the gulch. Because of extensive soil reworking, a test pitting investigation will be performed to determine if soil below or around this debris contains PCBs over 10 mg/kg.	Jeff Brownlee
6/19/2002	Update or Other Action	Staff observed a site investigation at Drury Gulch with the COE, Coast Guard and EPA. Seven test pits were advanced to help determine the amount of debris in the gulch. Auger refusals during a previous boring investigation led to suspicion that there was more debris than historical information suggested. Of seven test pits, six encountered substantial debris. The debris layer was generally about five to seven feet thick with two to three feet of overburden. The debris appeared to be sorted military industrial debris such and Quonset huts, truck parts, scattered drums, cable, piping and chain. The debris was intermixed with soil. The contaminant of concern at the gulch is PCBs. Composite samples of soil from the tailings of each test pit were taken for PCBs to characterize these soils as a possible waste stream. The Corps has been evaluating cleanup alternatives and was leaning towards excavation and treatment/disposal of all PCB contaminated soil (> 1 ppm in surface and > 10 ppm in subsurface) and then capping the site. However, the unexpectedly large volume of debris may make removal infeasible.	Jeff Brownlee
8/5/2002	Meeting or Teleconference Held	Staff met with the Corps of Engineers, COE contractor, US Coast Guard and the EPA to discuss planning for Drury Gulch. Based on a recent test pit investigation the team agreed that Drury Gulch was an unpermitted dump site and that groundwater-monitoring requirements have been met. Groundwater is not present in most areas of the gulch except for some sheet flow on bedrock during and after storm events. A schedule was agreed to finalize the RI/FS and prepare a Proposed Plan, public comment period and Record of Decision.	Jeff Brownlee
9/20/2002	Update or Other Action	Staff reviewed a draft proposed plan for Drury Gulch on Kodiak Island. The preferred remedy for the PCB contamination at the gulch is hot spot removal to <10 mg/kg, 2-feet plus soil cap, and institutional controls. The plan needed some editing and more discussion of alternative remedies, but otherwise looked good.	Jeff Brownlee
11/22/2002	Update or Other Action	Staff reviewed a draft decision document for Drury Gulch. The gulch is an approximately six acre site with sporadic PCB contamination in soil. An intermittent drainage runs through the gulch and into a drainage ditch about half a mile long. Some contaminant transport has occurred through sediment movement. The preferred remedy for is removal and off-site disposal of soil with concentrations over 10 mg/kg, a two-foot soil cap and institutional controls. The drainage ditch will be rerouted and the old one backfilled. The decision document has several deficiencies including omissions of previous field work, no maps or figures, and site information inconsistent with previous documents including the RI/FS and proposed plan. There was also no comparative analysis of alternatives. The EPA, Coast Guard and DEC have submitted comments and requested a rewrite of the draft document.	Jeff Brownlee
2/7/2003	Update or Other Action	Staff reviewed a draft final decision document for Drury Gulch. Drury Gulch is an approximately six acre site with sporadic PCB contamination in soil. An intermittent drainage runs through the gulch and into a drainage ditch about half a mile long. Some contaminant transport has occurred through sediment movement. The preferred remedy for is removal and off-site disposal of soil with concentrations over 10 mg/kg, a two-foot soil cap and institutional controls. The drainage ditch will be rerouted and the old one backfilled. The work is scheduled for this summer	Jeff Brownlee
4/3/2003	Meeting or Teleconference Held	CSRP staff will be participating in a public meeting and Open House this week with the Corps of Engineers in Kodiak. The purpose of our participation is to introduce the Drury Gulch Proposed Plan. The preferred alternative is to excavate soil hot spots over 10 mg/kg PCB concentrations, cover the historically disturbed area with two-feet plus of cover and revegitate. The area will also be controlled through land use restrictions. The gulch is on Coast Guard property and the Land Management Plan will be modified to protect the gulch from future industrial use or development. The Drury Gulch project was the topic of an article in the Kodiak Daily Mirror last week and the story was picked up by the Associated Press. The higher PCB concentrations mentioned in the article were removed off-island during a removal action three years ago.	Jeff Brownlee

The higher PCB concentrations mentioned in the article were removed off-island during a removal action three years ago.	Jeff Brownlee
5/23/2003	Cleanup Plan Approved	CS staff reviewed a workplan for remedial action at the Drury Gulch FUDS site on Kodiak Island. The six acre site is contaminated with PCBs in soil and sediment. The preferred remedy is hot spot removal of concentrations over 10 mg/kg PCB, capping all historically disturbed areas with a 2.5-foot soil cap, and institutional controls. The drainage ditch that drains the site has PCB concentrations in sediment up to 3 mg/kg. The ditch will be backfilled with clean soil. A new drainage ditch will be excavated parallel to the existing one. Previous investigations have identified 42 surface soil areas and five subsurface soil area that will require excavation and off-site disposal (Oregon). The removal strategy is to remove 200 cubic feet (10’ x 10’ x 2’ deep) of soil around previously detected hot spots. The excavation will then be screened at nine locations with immunoassay test kits with both discrete and composite sampling. Screening levels that indicate concentrations approaching the cleanup criteria will be confirmed with laboratory sampling. Discrete samples will be collected at all grid point locations along with any composite sampling in case follow up screening or off site lab analysis is required.	Jeff Brownlee
6/6/2003	Meeting or Teleconference Held	CS staff participated in a public Open House and Kodiak Island Borough Assembly meeting in Kodiak. The COE Alaska District presented the work planned for the summer including additional soil removal at Cape Chiniak Tracking Station and Little Navy Annex, beginning remedial action at the Drury Gulch PCB site and the foamed asphalt paving project. There was little public interest at the Open House.	Jeff Brownlee
6/19/2003	Record of Decision	CS staff reviewed and approved a Decision Document for the Drury Gulch FUDS in Kodiak, Alaska. The preferred remedy for this six acre PCB site is soil hot spot removal over 10 mg/kg with a two-foot soil cap over all historically disturbed areas. A long-term monitoring plan and institutional control plan will be developed with the Coast Guard (land owner). The decision document outlines the general scope and objectives of both plans	Jeff Brownlee
8/14/2003	Cleanup Plan Approved	CS staff approved a cleanup plan for the Drury Gulch FUDS in Kodiak. This site is contaminated with PCBs in soil. The remedy will be to remove soils with PCB concentrations over 10 mg/kg for off-site disposal, cap the historically disturbed area with a 2-foot plus soil cap, and establish institutional controls to ensure the cap is not disturbed and remains in good shape in the future.	Jeff Brownlee
8/19/2003	Institutional Control Record Established	Site land use controls and notification to DEC and COE in the case of soil disturbance. Site also included in the USCG Land Use Control Assurance Plan.	Jeff Brownlee
9/5/2003	Meeting or Teleconference Held	CS staff attended and participated in a Kodiak Island Borough assembly meeting and public open house for FUDS on Kodiak. The COE updated the assembly on the status of current and upcoming projects. There was minimal community interest at the open house	Jeff Brownlee
9/18/2003	Meeting or Teleconference Held	CS staff attended and participated in a Kodiak Island Borough assembly meeting and public open house for FUDS on Kodiak. The COE updated the assembly on the status of current and upcoming projects. There was minimal community interest at the open house	Jeff Brownlee
6/17/2004	Update or Other Action	File number assigned and entered into the Fileroom DB and CS DB.	Alyce Hughey
8/19/2004	Update or Other Action	Contaminated Sites staff performed site inspections at several formerly used defense sites on Kodiak Island. Building A-711 and the Fire Training Pit are currently being investigated and the preferred remedial remedy is being implemented at Drury Gulch. Non-aqueous phase liquid (NAPL) was found in a well at Building A-711 beyond the known plume boundary. NAPL was also noted in an open-hole boring downgradient of the Fire Training Pit toward the Buskin River. The work at Drury has been on hold temporarily while a data quality problem is worked out. The contract laboratory discovered that the lab method (Accelerated Solvent Extraction) for PCB analysis was biasing the results low so the majority of samples were rerun using a different method (sonification). The contractor is analyzing the data and planning a strategy to incorporate the new information	Jeff Brownlee
9/29/2004	Update or Other Action	Contaminated Sites staff performed site inspections at several Formerly Used Defense Sites on Kodiak. The Drury Gulch site is currently being excavated and remediated by hot spot excavation and off-site disposal. The EPA, Coast Guard and DEC have ongoing concern with the storm water prevention measures that are being used at the site. There are several areas with fines exposed that have produced visible turbidity leaving the site during rain events while equipment is moving. We are discussing ways to eliminate this runoff by not working during rain events or demobing for the season and preparing the excavations for winter by placing geofabric and clean fill	Jeff Brownlee
10/27/2004	Meeting or Teleconference Held	staff participated in a Kodiak Island Borough Assembly meeting to discuss the status of Formerly Used Defense Sites on the island. The Corps of Engineers also participated at the meeting. The DEC and COE contractor also participated in a public open house to solicit comments on the cleanup work being done on Kodiak. Turnout was light as is typical in Kodiak	Jeff Brownlee
1/19/2005	Update or Other Action	Contaminated Sites staff reviewed a water quality compliance document produced by the Corps of Engineers to clarify the regulatory criteria for storm water discharge from the Drury Gulch PCB site. The EPA and Coast Guard also were involved in the regulatory interpretation for the site. During construction of the remedial design the surface water criteria will be held to drinking water standards of 0.5 parts per billion PCBs at the site boundary. A level of 0.03 parts per billion PCBs will be held at the end of the storm drain which is an ecological benchmark for marine waters	Jeff Brownlee
6/17/2005	Meeting or Teleconference Held	Contaminated Sites staff participated in a public open house for Formerly Used Defense Sites on Kodiak Island. Staff also conducted several site inspections. Proposed Plans for the Little Navy Annex Site and the Cape Chiniak Site were introduced at the Kodiak Island Borough assembly meeting. The open house had a moderate amount of interest with several community members stopping by to discuss sites and pick up information.	Former Staff
6/27/2005	Update or Other Action	An Explanation of Significant Differences (ESD) was signed to amend the cleanup decision document for PCB contamination in Drury Gulch within the Kodiak Army/Navy Formerly Used Defense Site. During cleanup work in 2004, the volume of PCB contamination was found to be significantly larger than estimated in the original decision document. An additional ~8,000 tons of contaminated soil need to be addressed and the cost estimate has increased by ~$4.5 million. The overall cleanup approach of excavating to < 10 mg/kg PCB, capping, rerouting a drainage channel and institutional controls has not changed.	Jeff Brownlee
8/30/2005	Update or Other Action	Contaminated Sites staff participated in site inspections at several Formerly Used Defense Sites on Kodiak Island. The EPA and the Corps of Engineers contractor also participated in the inspections. Sites visited include Cape Chiniak, Long Island, Millers Field, Asphalt Disposal Area, Drury Gulch, Building A-711, and the Airport Staging Area	Jeff Brownlee
1/19/2006	Meeting or Teleconference Held	Contaminated Sites staff participated in a Kodiak Island Borough Assembly meeting to discuss the recent documents available for the review and the field work the COE will be doing this summer in the island. The COE and DEC were interviewed on public radio to discuss the Kodiak projects and overall contaminated site cleanup process. There was also a public open house to give community members the opportunity to bring up concerns and ask questions in person. As typical for Kodiak turn out was light	Jeff Brownlee

6/1/2006	Meeting or Teleconference Held	Staff participated with the Corps of Engineers (COE) and their contractor in a public open house for the Formerly Used Defense Sites on Kodiak Island. We also attended the Kodiak Island Borough Assembly meeting. The COE gave a briefing on the work planned for this summer. The open house showed light interest which is normal for Kodiak. Staff also met with Coast Guard environmental personnel and inspected several sites on the Coast Guard Base	Jeff Brownlee
6/20/2006	Update or Other Action	Contaminated Sites staff reviewed an after action report for the 2005 field work conducted at the Drury Gulch FUDS on Kodiak Island. Approximately 6,200 tons of PCB impacted soil was excavated for off-site disposal. Of this about half was over 50 mg/kg. The field season started with 18 separate excavations, but many of these merged over the summer. The excavations are being done on a five foot grid system with confirmation samples being taken on the corners. For every sample over 10 mg/kg a cube five-feet by five-feet by two feet deep is excavated, then resampled. The contractor anticipates finishing the project this field season. The Gulch will be capped with a two-foot plus cover and revegitated. The project is on Coast Guard property and will carry institutional controls	Jeff Brownlee
9/14/2006	Update or Other Action	Contaminated Sites staff reviewed a Land Use Assurance Plan for Environmental Activities for the U.S. Coast Guard Base in Kodiak. The document outlines a plan to track institutional controls (ICs) at the various contaminated sites on base. There are currently about fifteen sites on base with institutional controls. The plan objective is for the Coast Guard Environmental Section to screen contractor and other activity such as above or below ground construction, well drilling, etc. against the sites listed in the plan. Work can then be tailored to meet any existing ICs	Jeff Brownlee
9/19/2006	Update or Other Action	Staff participated in site inspections at several Formerly Used Defense Sites and Coast Guard sites at Kodiak. The EPA and Coast Guard also participated in the inspections. Remedial actions were being conducted at Drury Gulch, Airport Staging Area Fire Training Pit and Building A-711. The team spent a fair amount of time going over historic data with the contractor for the PCB cleanup at Drury Gulch. We also observed a test run of direct push sampling using a Geoprobe rig at the gulch for sampling data gap areas that were erroneously backfilled due to an extraction method error at the lab	Jeff Brownlee
3/5/2007	Meeting or Teleconference Held	Contaminated Sites staff participated in an annual update meeting for the formerly used defense sites on Kodiak Island. The meeting was held in Seattle and attended by representatives for the Corps of Engineers (COE), Coast Guard, Environmental Protection Agency, and DEC. The agenda concentrated on three sites that are in active investigation or remediation, the Fire Training Pit, Building A-711 and the Drury Gulch Polychlorinated Biphenyl (PCB) cleanup. The Fire Training Pit is in the beginning of a 16 month pilot study test using sparging to enhance natural biodegradation of the smear zone contamination. Building A-711 has completed a pilot study using an oxygen enhancer to attempt chemical oxidation of a fairly large heavy end petroleum plume. The pilot study showed that the total oxygen demand of the system was too large to overcome without being cost prohibitive. The oxidant was also show to mobilize lighter fraction hydrocarbons into the aquifer. The alternative option discussed were limited removal of the most impacted area. We will also revisit monitored natural attenuation as the plume is almost immobile. The majority of the meeting centered on the PCB cleanup at Drury Gulch. The team discussed the past work summary, estimated quantities in place, path forward to completion, storm water controls, and the use of the 95% upper confidence limit	Jeff Brownlee
5/17/2007	Meeting or Teleconference Held	Contaminated Sites staff reviewed a work plan and participated in a scoping meeting for continued remedial action at the Drury Gulch Formerly Used Defense Site (FUDS) in Kodiak. PCBs in soil over 10 mg/kg are being removed from the former Navy debris dump. A two foot soil cap is being installed over all disturbed areas, and an approximately 2000-foot drainage ditch will be realigned. Over the last two seasons about 10,000-tons of PCB contaminated soil has been removed about half being TSCA waste (over 50 mg/kg). About 3,000-tons of impacted soil is estimated to remain	Jeff Brownlee
6/14/2007	Meeting or Teleconference Held	Contaminated Sites staff participated in public meetings and site inspections for the Kodiak Formerly Used Defenses Sites (FUDS) on Kodiak Island. Three FUDS are active this summer including a continuing PCB removal at Drury Gulch, a below water smear zone excavation at Building A-711 and a biosparge pilot test at the Fire Training Pit. The Corps of Engineers and their contractor participated in a public open house and Kodiak Island Borough assembly meeting. Turnout was light for the open house, which is typical for Kodiak	Jeff Brownlee
11/2/2007	Meeting or Teleconference Held	Contaminated Sites staff participated in a Kodiak Island Borough Assembly meeting and public open house for the semiannual community update on the Formerly Used Defense Sites on Kodiak Island. The Corps of Engineers and their contractor also participated in the meetings. PCB impacted soil is continuing to be removed from Drury Gulch. About 860-tons of TSCA material and 1,500-tons of non-TSCA material have been removed this season with an estimated 700-tons remaining over cleanup levels. The diesel and residual range organic impacted soil removal has been completed at Building A-711. Approximately 16,000-tons of impacted soil was removed and stockpiled for future on island thermal remediation. The Airport Staging Area Fire Training Pit biosparging pilot study continues to operate with periodic groundwater and soil gas monitoring to evaluated performance. Interest was moderate at the open house with several people stopping by to discuss projects	Jeff Brownlee
3/13/2008	Update or Other Action	Contaminated Sites staff reviewed and commented on a draft work plan for continued remedial action at the Drury Gulch Formerly Used Defense Site (FUDS) on Kodiak Island. Soils impacted with PCBs above 10 mg/kg are being removed and disposed off island. There are about 2,400-tons estimated to be removed and disposed off island. An approximate 2,000-foot drainage channel will be backfilled and re-excavated parallel to the original. The low concentrations of PCB in sediment in the channel are then considered soil and don’t have to be removed. All disturbed areas in the gulch and drainage channel will be covered with a minimum of 2.5-feet of clean soil	Jeff Brownlee
4/2/2008	Meeting or Teleconference Held	Contaminated Sites staff participated in an update meeting for the Formerly Used Defense Sites on Kodiak Island. The Fire Training Pit, Drury Gulch, and Buskin Beach sites will be undergoing active remediation this summer. Environmental investigations will be performed at Building A-711, Buskin Beach and the Fire Training Pit. Proposed Plans are being produced this summer for Building A-711, Fire Training Pit, Asphalt Disposal Area and Buskin Beach and a closure report for an Underground Storage Tank cleanup at Bruhn Point. The spring open house and assembly meeting will be the end of May or early June	Jeff Brownlee
4/2/2008	Meeting or Teleconference Held	Contaminated Sites staff participated in a comment resolution meeting for work this summer at the Drury Gulch Formerly Used Defense Site on Kodiak Island. The Corps of Engineers is administering the contract to cleanup the former Navy disposal site that is impacted with PCBs. There is an estimated 2,000-tons of impacted soil left to remove which has been running about 1/3 TSCA (soil with samples over 50 mg/kg). The COE is using immunoassay test kits to drive excavation and agreed to do an upfront correlation test to check the confidence of the screening performance. In addition to the soil removal a 2,000-foot drainage ditch with be covered and another one dug parallel to eliminate PCB is sediment in the current ditch. All disturbed areas will then be covered with 2.5-feet of cover material, graded and revegetated	Jeff Brownlee
5/22/2008	Update or Other Action	Contaminated Sites staff reviewed a geotechnical report concerning slope stability at a Formerly Used Defense Site (FUDS). The Drury Gulch site is actively being excavated of polychlorinated biphenyl impacted soils over 10 mg/kg. An portion of the excavation is against the toe of a steep slope and the Corps of Engineers was concerned that the slope above may destabilize and threaten the foundation of a building at the top of the hill. The investigation concluded that the intended soil removal should not destabilize the slope and the building is relatively safe	Jeff Brownlee
8/12/2008	Site Visit	Contaminated Sites staff conducted site inspections with the EPA and Coast Guard at several Formerly Used Defense Sites (FUDS) and Coast Guard sites on Kodiak Island. Field work had been done this season at Building A-711, Building A-141, Drury Gulch, Airport Staging Area, and the Site 3 Laundry. PCB and TCE soil removals have been completed at Drury Gulch and the contractor is working on the cap over the entire gulch and the drainage channel realignment. The biosparging pilot study at the Fire Training Pit is being evaluated and the cleanup team has decided to go back to the feasibility study and consider other remedial alternatives for the site	Jeff Brownlee
1/22/2009	Meeting or Teleconference Held	Contaminated Sites staff participated with the Corps of Engineers in a Kodiak Island Borough Assembly meeting and a public open house to discuss Formerly Used Defense Sites on Kodiak Island. An update was provided on sites currently being worked on including Drury Gulch, Buskin Beach, Airport Staging Area, and Building A-711	Jeff Brownlee
3/19/2009	Meeting or Teleconference Held	Contaminated Sites staff participated in an annual scoping meeting with the Corps of Engineers, EPA and Coast Guard for the Kodiak FUDS projects. Agenda items included review of the 2008 field season, and planned investigations and remedial actions at Building A-711, Airport Staging Area and various Coast Guard Sites including the Lube Pits, Building A-141, Buskin Beach, and the Asphalt Disposal Area	Jeff Brownlee
6/29/2009	Site Visit	At the request of the project manager, a site visit was conducted to oversee workplan compliance at the Drury Gulch site, a FUDS site on Kodiak Island, in August of 2008. Through the interview process of site workers and consutlants no deviations from the approved work plan were noted.	Brenton Porter
5/20/2010	Site Visit	Contaminated sites staff conducted site visits and meetings for several Kodiak FUDS including Building A-711, Drury Gulch, Airport Staging Area, and Buskin Beach. Staff conducted an extensive site walk of Drury Gulch which experienced significant erosion and sedimentation onto the cap as a result of a 100-year storm event during which 8 inches of rain fell on Kodiak Island within 24 hours. The USACE is conducting long term monitoring at both Drury Gulch and Building A-711. Groundwater sampling was conducted at A-711 during the week of this site visit. Sediment will be sampled from the cap surface, outside the fenced area, and in the lower drainage areas of Drury Gulch later this summer. Extensive erosion control, reseeding, and sediment removal is also planned later in 2010. The Airport Staging Area is also being scheduled for a round of groundwater monitoring for October 2010. The site visit was attended by USACE, ADEC, and contracted FES personnel. A meeting was conducted on May 21 with USCG environmental management staff at the Kodiak Base Support Unit to discuss the status of visited sites with emphasis on the storm water drainage issues resulting from Drury Gulch.	Curtis Dunkin
9/22/2010	Site Visit	During an annual site prioritization meeting on Kodiak with representatives from the EPA, USCG, USACE, and ADEC, contaminated sites staff conducted site visits at the following Kodiak FUDS: Drury Gulch/Site 18, Building A711, Airport Staging Area, Former Navy Landfill/Red Lake Site 2, Buskin Beach, and the Site 9 AvGas Tank Farm.	Curtis Dunkin
4/19/2012	Site Visit	ADEC conducted a site visit and inspection during the sediment sampling effort conducted in the airport drainage system which is down gradient of Drury Gulch and flows and discharges to Womens Bay.	Curtis Dunkin
9/30/2015	Site Visit	CS staff conducted a site inspection to observe the site status and condition as well as the extent of damage to the stormwater drainage system resulting from several significant storm events over the past year. Staff walked and inspected the adjacent drainage systems associated with Drury Gulch and evaluated potential rerouting solutions. Also present on the site inspection were representatives from the Army Corps of Engineers, the EPA, and the USCG.	Curtis Dunkin

Update or Other Action

Staff reviewed a Remedial Investigation/Feasibility Study for Drury Gulch near the Coast Guard Base on Kodiak Island. The Gulch was used a metals debris dump in the 1960s and 1970s by the Navy and Army. A debris cleanup in the late 1970s appears to have spread PCB contaminated soil over a large area (approximately 6 acres). Investigations show that about 8,000 cubic yards of soil are impacted with PCBs over 10 mg/kg. The RI/FS did not include historical data from three previous investigations, so the ADEC is requesting a rewrite of the draft to include all available data. The Feasibility Study was limited to three options, the preferred one being excavation and offsite disposal of soil with concentrations over 10 mg/kg and placing a two-foot cap over the site.

Jeff Brownlee

3/21/2001

Meeting or Teleconference Held

Staff participated in a comment resolution meeting for a Draft RI/FS for Drury Gulch. This former metals dump has several thousand cubic yards of PCB impacted soil over 10 mg/kg. Attendees included the COE and their contractor, the U.S. Coast Guard and the EPA. Several concerns were addressed including the COE not using all available historical data for the Feasibility Study and that too few remedial alternatives were evaluated. Terrestrial ecological pathways were not adequately evaluated. The COE will issue a Draft Final for the cleanup teams review and concurrence prior to beginning work on the remedial design workplan.

Jeff Brownlee

5/4/2001

Meeting or Teleconference Held

Staff participated in a Kodiak Island Borough assembly meeting and public open house in Kodiak. The Corps of Engineers and their contractor, Jacobs engineering also attended. Three potential new sites were inspected based on community input. Overall interest seemed light, which has been normal in Kodiak.

12/5/2001

Meeting or Teleconference Held

Staff attended a comment resolution and scoping meeting for the Drury Gulch site. The Corps of Engineers and their contractor (Jacobs), the EPA and their contractor (Tetra Tech), the Coast Guard and the ADEC attended the meeting at the Coast Guard offices in Seattle. The comment resolution was for the RI/FS document. Comments on the document were minimal, however a decision was not made on the preferred remedy. To finalize the RI/FS the COE will need to produce a long-term monitoring plan, institutional control plan, perform a round of well sampling and complete the requested ecological screening work. The schedule for the proposed plan and record of decision was discussed as well as the possibility of doing an interim removal action this summer to take advantage of available funding.

Jeff Brownlee

4/29/2002

Site Characterization Workplan Approved

Staff reviewed a workplan for an additional investigation at this former Navy disposal area on Kodiak Island. Drury Gulch has PCB contamination in soils over an approximately six-acre area and some impacts to sediment in a small drainage through the gulch. During previous investigations debris has been encountered during borings. The debris is inferred to be left from the original waste deposited in the gulch. Because of extensive soil reworking, a test pitting investigation will be performed to determine if soil below or around this debris contains PCBs over 10 mg/kg.

Jeff Brownlee

6/19/2002

Update or Other Action

Staff observed a site investigation at Drury Gulch with the COE, Coast Guard and EPA. Seven test pits were advanced to help determine the amount of debris in the gulch. Auger refusals during a previous boring investigation led to suspicion that there was more debris than historical information suggested. Of seven test pits, six encountered substantial debris. The debris layer was generally about five to seven feet thick with two to three feet of overburden. The debris appeared to be sorted military industrial debris such and Quonset huts, truck parts, scattered drums, cable, piping and chain. The debris was intermixed with soil. The contaminant of concern at the gulch is PCBs. Composite samples of soil from the tailings of each test pit were taken for PCBs to characterize these soils as a possible waste stream. The Corps has been evaluating cleanup alternatives and was leaning towards excavation and treatment/disposal of all PCB contaminated soil (> 1 ppm in surface and > 10 ppm in subsurface) and then capping the site. However, the unexpectedly large volume of debris may make removal infeasible.

Jeff Brownlee

8/5/2002

Meeting or Teleconference Held

Staff met with the Corps of Engineers, COE contractor, US Coast Guard and the EPA to discuss planning for Drury Gulch. Based on a recent test pit investigation the team agreed that Drury Gulch was an unpermitted dump site and that groundwater-monitoring requirements have been met. Groundwater is not present in most areas of the gulch except for some sheet flow on bedrock during and after storm events. A schedule was agreed to finalize the RI/FS and prepare a Proposed Plan, public comment period and Record of Decision.

Jeff Brownlee

9/20/2002

Update or Other Action

Staff reviewed a draft proposed plan for Drury Gulch on Kodiak Island. The preferred remedy for the PCB contamination at the gulch is hot spot removal to <10 mg/kg, 2-feet plus soil cap, and institutional controls. The plan needed some editing and more discussion of alternative remedies, but otherwise looked good.

Jeff Brownlee

11/22/2002

Update or Other Action

Staff reviewed a draft decision document for Drury Gulch. The gulch is an approximately six acre site with sporadic PCB contamination in soil. An intermittent drainage runs through the gulch and into a drainage ditch about half a mile long. Some contaminant transport has occurred through sediment movement. The preferred remedy for is removal and off-site disposal of soil with concentrations over 10 mg/kg, a two-foot soil cap and institutional controls. The drainage ditch will be rerouted and the old one backfilled. The decision document has several deficiencies including omissions of previous field work, no maps or figures, and site information inconsistent with previous documents including the RI/FS and proposed plan. There was also no comparative analysis of alternatives. The EPA, Coast Guard and DEC have submitted comments and requested a rewrite of the draft document.

The area will also be controlled through land use restrictions. The gulch is on Coast Guard property and the Land Management Plan will be modified to protect the gulch from future industrial use or development. The Drury Gulch project was the topic of an article in the Kodiak Daily Mirror last week and the story was picked up by the Associated Press. The higher PCB concentrations mentioned in the article were removed off-island during a removal action three years ago.

Cleanup Plan Approved

CS staff reviewed a workplan for remedial action at the Drury Gulch FUDS site on Kodiak Island. The six acre site is contaminated with PCBs in soil and sediment. The preferred remedy is hot spot removal of concentrations over 10 mg/kg PCB, capping all historically disturbed areas with a 2.5-foot soil cap, and institutional controls. The drainage ditch that drains the site has PCB concentrations in sediment up to 3 mg/kg. The ditch will be backfilled with clean soil. A new drainage ditch will be excavated parallel to the existing one. Previous investigations have identified 42 surface soil areas and five subsurface soil area that will require excavation and off-site disposal (Oregon). The removal strategy is to remove 200 cubic feet (10’ x 10’ x 2’ deep) of soil around previously detected hot spots. The excavation will then be screened at nine locations with immunoassay test kits with both discrete and composite sampling. Screening levels that indicate concentrations approaching the cleanup criteria will be confirmed with laboratory sampling. Discrete samples will be collected at all grid point locations along with any composite sampling in case follow up screening or off site lab analysis is required.

Update or Other Action

Contaminated Sites staff performed site inspections at several formerly used defense sites on Kodiak Island. Building A-711 and the Fire Training Pit are currently being investigated and the preferred remedial remedy is being implemented at Drury Gulch. Non-aqueous phase liquid (NAPL) was found in a well at Building A-711 beyond the known plume boundary. NAPL was also noted in an open-hole boring downgradient of the Fire Training Pit toward the Buskin River. The work at Drury has been on hold temporarily while a data quality problem is worked out. The contract laboratory discovered that the lab method (Accelerated Solvent Extraction) for PCB analysis was biasing the results low so the majority of samples were rerun using a different method (sonification). The contractor is analyzing the data and planning a strategy to incorporate the new information

Update or Other Action

Contaminated Sites staff performed site inspections at several Formerly Used Defense Sites on Kodiak. The Drury Gulch site is currently being excavated and remediated by hot spot excavation and off-site disposal. The EPA, Coast Guard and DEC have ongoing concern with the storm water prevention measures that are being used at the site. There are several areas with fines exposed that have produced visible turbidity leaving the site during rain events while equipment is moving. We are discussing ways to eliminate this runoff by not working during rain events or demobing for the season and preparing the excavations for winter by placing geofabric and clean fill

Update or Other Action

An Explanation of Significant Differences (ESD) was signed to amend the cleanup decision document for PCB contamination in Drury Gulch within the Kodiak Army/Navy Formerly Used Defense Site. During cleanup work in 2004, the volume of PCB contamination was found to be significantly larger than estimated in the original decision document. An additional ~8,000 tons of contaminated soil need to be addressed and the cost estimate has increased by ~$4.5 million. The overall cleanup approach of excavating to < 10 mg/kg PCB, capping, rerouting a drainage channel and institutional controls has not changed.

Update or Other Action

Contaminated Sites staff reviewed an after action report for the 2005 field work conducted at the Drury Gulch FUDS on Kodiak Island. Approximately 6,200 tons of PCB impacted soil was excavated for off-site disposal. Of this about half was over 50 mg/kg. The field season started with 18 separate excavations, but many of these merged over the summer. The excavations are being done on a five foot grid system with confirmation samples being taken on the corners. For every sample over 10 mg/kg a cube five-feet by five-feet by two feet deep is excavated, then resampled. The contractor anticipates finishing the project this field season. The Gulch will be capped with a two-foot plus cover and revegitated. The project is on Coast Guard property and will carry institutional controls

Meeting or Teleconference Held

Contaminated Sites staff participated in an annual update meeting for the formerly used defense sites on Kodiak Island. The meeting was held in Seattle and attended by representatives for the Corps of Engineers (COE), Coast Guard, Environmental Protection Agency, and DEC. The agenda concentrated on three sites that are in active investigation or remediation, the Fire Training Pit, Building A-711 and the Drury Gulch Polychlorinated Biphenyl (PCB) cleanup. The Fire Training Pit is in the beginning of a 16 month pilot study test using sparging to enhance natural biodegradation of the smear zone contamination. Building A-711 has completed a pilot study using an oxygen enhancer to attempt chemical oxidation of a fairly large heavy end petroleum plume. The pilot study showed that the total oxygen demand of the system was too large to overcome without being cost prohibitive. The oxidant was also show to mobilize lighter fraction hydrocarbons into the aquifer. The alternative option discussed were limited removal of the most impacted area. We will also revisit monitored natural attenuation as the plume is almost immobile. The majority of the meeting centered on the PCB cleanup at Drury Gulch. The team discussed the past work summary, estimated quantities in place, path forward to completion, storm water controls, and the use of the 95% upper confidence limit
