Action Date	Action	Description	DEC Staff
12/12/2001	Institutional Control Record Established	This IC was established before this site had been identified. It was entered on 1/4/06 as part of routine database maintenance. 1. All organizations conducting activities on United States Army Alaska (USARAK) controlled land are responsible for complying with established institutional controls (ICs). ICs are administrative, procedural, and regulatory measures to control human access to and usage of property. They are applicable to all known or suspected contaminated sites where contamination has been left in place. 2. These controls have been established to implement the selected remedial actions agreed upon by the U.S. Army (Army), the U.S. Environmental Protection Agency (USEPA), and the Alaska Department of Environmental Conservation (ADEC) in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) as amended by the Superfund Amendment Reauthorization Act (SARA). These controls also apply to remedial actions agreed upon under Two-Party Compliance Agreements. These agreements are concluded between USARAK and ADEC and apply to petroleum/oil/lubricants- (POL) contaminated sites. 3. ICs such as limitations on access, water use, excavations, and property transfers will supplement engineering controls as appropriate for short-term and long-term management to prevent or limit human and environmental exposure to hazardous substances, pollutants, or contaminants. Specific ICs include, among other things: limitations on the depth and location of excavations, prohibition of or restrictions on well drilling and use of ground water, requirements for worker use of personal protective equipment, site monitoring, and prohibition of certain land uses, types of vehicles, etc. 4. Organizational units, tenants, and support/contractor organizations must obtain an Excavation Clearance Request (ECR) for all soil disturbing activities impacting soils six inches or more below the ground surface. The review process for approval of an ECR begins with the identification of the current status (known or suspected hazardous waste site or “clean” site) of a work location. ECR’s for work in known or suspected hazardous waste sites: a. will include specific limitations and controls on such work; b. will include specific IC procedures, and notification, monitoring, reporting, and stop work requirements; c. may include procedures for management, characterization, and disposal of any soil or groundwater encountered or removed; d. will identify “project managers” for both the unit/contractor requesting the work and DPW Environment Resources. 5. The DPW project manager will conduct on-site inspections of each work site (at which ICs apply) to determine continued compliance with the terms and conditions of the approved ECR. DPW has the authority to revoke ECR approval if the specified terms and conditions are not being met. ECR forms are available at the Customer Service Desks at: a. Building 730 at Fort Richardson; b. Building 3015 at Fort Wainwright; c. Building 605 at Fort Greely. 6. USARAK has negotiated (with USEPA and/or ADEC) decision documents and/or Records of Decision (RODs) that mandate the implementation of ICs USARAK Directorate of Public Works, Environmental Resources Department (PWE), maintains copies of all decision documents and RODs requiring ICs in its real property files. PWE provides regularly updated post maps showing all areas affected by ICs. These maps can easily be accessed by using an approved intranet mapping interface application. Copies of these maps will be available to each directorate, activity, and tenant organization. To ensure the effectiveness of ICs, all organizational units and tenant activities will be informed on an annual basis of ICs on contaminated soils and groundwater in effect near their facilities. 7. ICs are enforceable by the U.S. Environmental Protection Agency (USEPA) and the Alaska Department of Environmental Conservation (ADEC). Failure to comply with an IC mandated in a decision document or ROD will violate the USARAK Federal Facility Agreement and may result in stipulated fines and penalties. This does not include the costs of corrective actions required due to violation of an established IC.	Richmond, Sharon

08/09/2005	Spill Transferred from Prevention and Emergency Response Program		Richmond, Sharon
08/10/2005	Meeting or Teleconference Held	Staff met with DPW to discuss sampling results and conduct a site visit. A work plan for additional site characterization and management of contaminated soil is expected within one week.	Richmond, Sharon
08/11/2005	Site Added to Database		DeRuyter, Kim
08/12/2005	Update or Other Action	Received laboratory analysis reports with all sampling data to date.	Richmond, Sharon
09/06/2005	Meeting or Teleconference Held	The Army held a Town Hall meeting to inform the public about the status of this site. Site Characterization is ongoing. The area with highest impacts is larger than thought. The Army shut down construction until it's determined which areas are clean. The public was assured that the drinking water is clean and the Army offered free blood tests for PCBs to residents, workers, and Army personnel.	Richmond, Sharon
09/12/2005	Meeting or Teleconference Held	ADEC attended a teleconference with the Army, the Corps, and the EPA to discuss site status. Preliminary data was distributed; the Corps' chemist was in the process of reviewing the data. Surface soil samples from the northern portion of the site were all below 1 mg/kg. All parties agreed thatthis area could be opened so that structures and utilities could be winterized.	Richmond, Sharon
09/12/2005	Update or Other Action	Received preliminary lab data. Wipe samples from playground equipment and houses outside of construction site did not detect PCBs. Soil at one house had low-level detection of PCBs but below cleanup level of 1 mg/kg. The Army was in the process of preparing a flyer to distribute to residents.	Richmond, Sharon
09/15/2005	Meeting or Teleconference Held	Contaminated Sites (CS) staff participated in multiple meetings with the US Army, the Corps, and the Environmental Protection Agency (EPA). Preliminary laboratory data indicate that polychlorinated biphenyls (PCBs) were not detected on houses and playground equipment outside of the construction site. PCBs were detected in the driveway and front yard of the house closest to the construction site but concentrations were less than the cleanup level of 1 mg/kg. This information was hand-delivered to residents in the form of a pamphlet on Wednesday evening (9/14/05). Preliminary laboratory data also indicate that no surface samples collected in the northern portion of the construction site contained PCBs above the cleanup level and the EPA, the Army and ADEC agree that this area can be reopened so that existing structures and utilities can be winterized. The southern contaminated portion of the site has been fenced and measures will be taken to completely cover or containerize contaminated soil over the winter. No houses in this development are occupied nor will they be occupied this winter. At the request of the Army, the EPA and ADEC will send a letter to the Army indicating that surface soil in the northern area is clean and that winterization activities can proceed with restrictions on various activities and procedures.	Richmond, Sharon
09/15/2005	Meeting or Teleconference Held	ADEC attended a teleconference with the Army and EPA to discuss restrictions necessary to ensure worker safety when the northern portion of site will be reopened for winterization.	Richmond, Sharon
09/15/2005	Update or Other Action	ADEC and EPA sent the Army a letter listing the conditions that must be met before construction workers re-enter the site for the purpose of winterizing existing housing units. The letter outlines increased security, training, and screening/sampling measures. Also, specifice areas have been designated as being open for surface and subsurface work, surface work only, or restricted access with hazardous waste-trained personnel accompanying workers. This letter was sent at the request of the Army and the Corps in response to OSHA concerns for worker safety.	Richmond, Sharon
09/28/2005	Meeting or Teleconference Held	Contaminated Sites staff participated in a teleconference with the Army and the Corps. After analyzing over 1,000 surface and subsurface samples for polychlorinated biphenyls (PCBs), project managers agreed to allow surface and subsurface construction to resume in the northern 1/3 of the of the site and surface-only work in the central 1/3, thereby allowing winterization of nearly 100 family housing units. Another 10 units may be released later this week. The contaminated area will be fenced off and the 20 housing units in this area will not be completed. It is not known if existing structures will affect a release investigation planned for next summer. Approximately 150 cubic yards of PCB-contaminated soil was shipped to Idaho for disposal.	Richmond, Sharon
10/12/2005	Meeting or Teleconference Held	Contaminated Sites staff participated in a teleconference with the Army. Staff agreed with the Army and the EPA that 40 hour HAZWOPER training would be most protective for workers entering the area most highly contaminated with PCBs. The final decision regarding HAZWOPER training will be determined by State OSHA. In addition, the Army's construction contractors have completed a drainage swale in the northern portion of this housing project. Field screening with a photoionization detector (PID) indicated that petroleum or other volatile organic contamination could be present in soil used to construct the swale. The area will be completely covered with visqueen and overlain with gravel until next spring when a site characterization and possible removal action will be carried out.	Richmond, Sharon
08/17/2006	Preliminary Assessment Approved	Over the spring and summer of 2006, a 2005 Work Plan Addendum and a Field Sampling Plan with six addenda were approved. A Preliminary Source Evaluation is ongoing.	Richmond, Sharon
08/17/2006	Meeting or Teleconference Held	Contaminated Sites staff participates in weekly meetings to discuss the ongoing site investigation, changes to dynamic work plan, and to address construction concerns. Meeting attendees include Army environmental staff, the Corps of Engineers, the Army consultants, and construction interests. Based upon information collected during the investigation, excavation has been limited to areas that have already been disturbed and backfilled with clean fill. Excavation is specifically prohibited in areas that have not been previously disturbed, for construction and investigative purposes. Monitoring well installation was permitted only in areas that have been determined to be free of metallic debris. Soil and groundwater data are pending.	Richmond, Sharon
08/17/2006	Update or Other Action	While investigating areas with substantial buried metal debris, a number of munitions-related items were discovered. All items showed evidence of demilitarization (i.e., none of the items were complete) but still contained some potentially explosive material. All items were taken to the Fort Wainwright Small Arms Firing Range and have been destroyed. Excavation at Taku Gardens is strictly prohibited in all previously undisturbed areas. An extensive site-wide geophysical survey and removal action will be necessary before this site is ready for residential occupation.	Richmond, Sharon
09/18/2006	Spill Transferred from Prevention and Emergency Response Program	Site transferred by PERP staff Toivo Luick. Spill no. 05309914703; spill date = 5/27/05; PERP file no. 108.02.010; substance = diesel range organics; volume unknown.

Hard copies will be distrubuted at the quarterly Federal Facilities Meeting to be held in Anchorage 27 Feb through 1 March, 2007. All interested parties will go over the PSE II and begin planning for a site investigation and possible remedial actions for Spring/Summer 2007.	Richmond, Sharon
02/20/2007	Meeting or Teleconference Held	CS staff attended the last regularly scheduled weekly meeting with the Army and the Corps of Engineers to address construction concerns. The construction crews have finished their work and have left the site. The entire construction site is fenced, gated, and locked. Access is restricted and is coordinated though the Directorate of Public Works. Future meetings will focus on continued site investigation and remediation.	Richmond, Sharon
02/26/2007	Spill Transferred from Prevention and Emergency Response Program	Site transferred by PERP staff Amanda Stark. Spill No. 06309931201; Spill Date = 11/8/06; PERP File No. 108.02.011; Substance = Glycol; Quantity = 850 Gallons; Location = Building 22; Latitude 64 40' 27.74"; Longitude -147 39' 43.89". Hydronic heating system malfunction resulted in the release of 850 gallons of glycol. Approximately 320 gallons were recovered from inside the housing unit and placed in bulk storage containers. Several cubic yards of snow mixed with glycol and gravel were shoveled into 12 open top 55-gallon drums. However, the drums were not certified clean and a waste determination is underway. Current status: ~530 gallons of glycol in the ground at Building 22 and DEC is awaiting sample/waste characterization report to determine disposal. PERP issued an NOV for late reporting.	Read, Mitzi
03/05/2007	Meeting or Teleconference Held	CS Staff attended the quarterly Federal Facilities Agreement meeting Feb 27 through March 1, 2007. March 1 was spent entirely on Taku Gardens. Topics of discussion included a review of the Preliminary Source Evaluation II (PSEII), a general path forward, and preliminary development of a timeline for actions. It is expected that a remedial investigation with removal actions will begin summer 2007. Additional geophysical work is planned for late March/early April 2007.	Richmond, Sharon
03/26/2007	Preliminary Assessment Approved	CS staff provided comments to the Preliminary Source Evaluations 1 (historical review) and PSE2 (results of 2006 field work). Both documents contain a great deal of information that will help guide future investigation.	Richmond, Sharon
03/27/2007	Meeting or Teleconference Held	DEC, the Army, EPA, and the Corps of Engineers will hold teleconference meetings at a minimum of every two weeks during planning, development and implementation of the Remedial investigation/Feasibility Study (RI/FS).	Richmond, Sharon
04/02/2007	Meeting or Teleconference Held	CS staff conducted a site visit to observe the geophysical survey performed by the US Army Corps of Engineers Cold Regions Research and Engineering Laboratories (CRREL). Survey methods include electromagnetic induction (EM61) and ground-penetrating radar. It is anticipated that all areas of concern will be surveyed before the summer field work begins. The purpose of the survey is to locate and delineate buried debris, including drums and scrap metal that could contain munitions-related items.	Richmond, Sharon
08/20/2007	Meeting or Teleconference Held	ADEC and EPA have met with the Army several times over the past few months preparing for a Remedial Investigation (RI)/Feasibility Study. The Army's contractors have submitted a comprehensive RI Management Plan that describes all work to be perfromed during the RI. Work will include installation and sampling of groundwater monitoring wells; subslab vapor sampling at every housing unit; installation and sampling of soil borings; removal of PCB-contaminated soil in the Exclusion Zone; a drum and debris removal in the former slough channel; trenching to examine debris in the newly discovered disposal areas in the southeast portion of the site and the northern disposal area; trenching in the munitions disposal area to allow safe installation of groundwater monitoring wells; sampling soil in the Sound Berm; and sampling and disposal of all stockpiled soil. Data collected this summer and next will be used in a baseline risk assessment. Plans for this work have been submitted and comments were provided as quickly as possible so that work could start this summer. Weekly meetings will be held while field work is ongoing.	Richmond, Sharon
09/04/2007	Meeting or Teleconference Held	Weekly meetings have resumed. Almost all components of the Remedial Investigation Management have been approved. Work has begun. Existing soil piles are being sampled and will either be disposed of at the Fort Wainwright Landfill or transported to an appropriate treatment facility. The large sound berm has been sampled to determine if it was built with contaminated oil. Sub-slab soil vapor samples have been collected at every building; installation of soil vapor probes in open areas is in progress. Removal of PCB contaminated soil and the drum/debris removal will begin this week. Installationo f monitoring wells is in progress.	Richmond, Sharon
09/11/2007	Meeting or Teleconference Held	Weekly meeting attended by DEC, Army, EPA, Corps, and contractors. Excavation of drum and debris disposal areas has begun. Most drums thus far have been empty; some contained asphalt-like material. The soil pile with heavy metal contamination has been loaded into shipping containers for transport to a hazardous waste facility. One inert munitions related item discovered among various scrap and crushed drums. Contractors prepping for PCB removal. Soil vapor sampling ongoing. DEC and EPA contractor visited site with the Army to view excavations.	Richmond, Sharon
10/08/2007	Meeting or Teleconference Held	Weekly meetings continue. Drum and debris removal is ongoing. One leaking drum of petroleum distillate was uncovered and contamianted soil removed. Multi-incremental sampling data for the soil piles left on-site during construction is arriving. Approximately 10,500 cubic yards of soil from the PCB exclusion zone will be disposed of at the Fort Wainwright Landfill. PCB-contaminated soil from the original B52 location will be excavated until concentrations are below the 1 mg/kg cleanup level. Soil with PCB >10 mg/kg will be shipped to RCRA waste facility; remaining soil will be disposed of at the landfill. The Army's contractors continue to install groundwater monitoring wells, soil vapor probes, more sub-slab soil vapor probes, test pits and soil borings. They will also investigate the metal anomaly in the NE of the site.	Richmond, Sharon
11/20/2007	Meeting or Teleconference Held	Taku meeting held. Both contractors have left the site. Field work complete for this season. Interim Draft Final Remedial Managment Plan and draft data reports pending. Next meeting Dec 18, 2007.	Richmond, Sharon
03/06/2008	Exposure Tracking Model Ranking	Initial ranking with ETM completed.	Richmond, Sharon
06/12/2008	Meeting or Teleconference Held	CS staff attended a meeting and site visit with the Army, EPA, USACE, and Army Environmental Center. Topics of discussion included DEC's letter of concern regarding the proposed depth of excavation for material in the "moderate to high" probability of encountering munitions or explosives of concern. A revision to the MEC work plan is expected. A meeting is planned to address data quality concerns for the near future.	Richmond, Sharon
10/31/2008	Meeting or Teleconference Held	Contaminated sites staff attended the final 2008 weekly field season teleconference. ** All excavations to date are presumed completed pending review and approval of analytical and geophysical data.** Any potential remaining contamination will be removed or included in the baseline risk assessment. Actions completed in 2007/2008: Building 15/17/19 munitions and scrap disposal area excavation, including movement and replacement of a live power pole to remove uncharacterized metal debris; installation of additional groundwater monitoring wells and the 2007/2008 spring and fall groundwater samplings; excavation of the Subarea A debris and munitions-scrap disposal area; excavation of the drum/debris disposal area north of the GVEA substation (Subarea D); excavation of the drum and debris disposal areas near Buildings 48 and 49; characterization of all soil piles remaining on site from construction and/or investigation; subsurface soil samples were collected across the site; transport of all known contaminated excavated soil to an appropriate treatment or disposal facility; sorting all metalic debris for potential hazards and transfer of all recyclable debris to a recycling facility; disposal of all potential munitions hazards at the Fort Wainwright Firing Range; excavation and disposal of all PCB contaminted soil; removal of the PCB exclusion zone fence; a hydrologic study around the drinking water well capture zone; a pilot test for sub-slab and indoor air. In 2008, sub-slab vapor samples were often not usable because very high concetrations of Freon (presumably from construciton materials) interfered wtih quantification of potential contaminants of concern; a modified TO-15 withsolvent delay has been developed and will be tesetd to see if this overcomes the dilution problems required with high Freon concetrations. The Remedial Investigation and Baseline Risk Assessment are expected to be released in April 2009. The Taku (OU6) FFA meeting will be held in January 2009.	Richmond, Sharon
11/13/2008	Meeting or Teleconference Held	staff met with Tetratech to discuss current site status.

09/29/2009	Meeting or Teleconference Held	Members of the CS staff met with the Army, EPA and their contractors to review comments on the draft Remedial Investigation.	Caillouet, Debra
10/16/2009	Site Characterization Workplan Approved	Staff reviewed the Technical Memorandum, October 15, 2009, Taku Building 49 Drum and Debris Removal. It describes the supporting of the garage and foundation at Taku Gardens Building 49 followed by excavation under the garage to remove debris and potentially contaminated soil. ADEC has no objection to the implementation of this work plan. The results of this investigation and debris removal will be included in the Interim Draft Remedial Investigation Report due early next year.	Caillouet, Debra
10/21/2009	Report or Workplan Review - Other	Technical Memorandum, Taku Gardens, 1,2,3-TCP Contamination Plume, October 13, 2009 was reviewed. It formalizes the work plan that was presented during the comment resolution meeting for the Remedial Investigation on September 30, 2009. ADEC has no objection to the execution of the work. Groundwater monitoring wells and Gore(TM) Modules will be installed to attempt to identify the source of the 1,2,3-Trichloropropane previously detected in several monitoring wells at Taku Gardens. The results will be reported in the Interim Draft Remedial Investigation Report.	Caillouet, Debra
01/25/2010	Update or Other Action	A letter was sent. The Alaska Department of Environmental Conservation (DEC) and the U.S. Environmental Protection Agency (EPA) are concerned that proper sampling and analysis to characterize the vapor intrusion exposure pathway at OU6 is not being conducted, which will hinder successful completion of the Remedial Investigation. The FFA in Paragraph 11.2 states “The Army’s Project Manager shall notify the U.S. EPA and ADEC Project Managers not less than fourteen business days in advance of any scheduled well drilling, sample collection, or other monitoring activity, conducted pursuant to this Agreement. The Project Mangers will be notified prior to any unscheduled sampling event.” The current sampling effort is being conducted in violation of this provision. Without adequate coordination, input and approvals, successful completion of the Remedial Investigation is unlikely. To better understand the Army’s anticipated schedule and to improve coordination on the project, DEC requests that the Army: 1. Provide minutes of each FFA meeting, including all action items, within two weeks after each meeting and request comments on or approval of the minutes. 2. Submit a draft a timetable for activities required by the OU-6 amendment to the FFA by February 12 for review and comment; after agreement of the Project Managers incorporate the timetable into Table 3 of the FFA. 3. Cease the current vapor sampling and submit a work plan to DEC and EPA for review. DEC and EPA are committed to working with the Army to ensure OU6 is adequately characterized and any necessary remedial actions are taken so the site can be returned to beneficial use. If you have any questions regarding this letter, please contact either of us.	Caillouet, Debra
