Problems/Comments

A Phase II Site Assessment conducted on the Bentley Mall property indicated concentrations of PCE (tetrachloroethene) and TCE (trichloroethene) above ADEC soil and water cleanup levels. The concentration of PCE and TCE are highest along the south boundary adjacent to College Road and in particular, the southeast corner. The highest level found in groundwater samples was 2,910 ug/l and the highest level for TCE found in groundwater samples was 97.5 ug/l. A soil sample taken between the East Satellite Building and the VIP Dry Cleaners at five feet bgs., had a high PCE reading of 0.294 mg/kg. A ground water investigation conducted during the winter 2004/2005 found that the PCE ground water plume extends beyond Noyes Slough into the northern portion of the Charles Slater Homestead Subdivision. PCE soil and groundwater contamination was detected on Fred Meyer-East property (Tax Lot 221 owned by the Bentley Family Charitable trust) during Phase I investigations dated July 2002 and September 2002. Tax Lot 221 is adjacent to and generally down gradient from the Bentley Mall property. See file 100.38.166 for other detected contaminants and details.

3/8/2005	Update or Other Action	Sent by email the latest ground water investigation report to Jim Desmond.	Douglas Bauer
3/30/2005	Meeting or Teleconference Held	Telephone conversation with Lyle Gresehover with Alaska Resources and Environment: preliminary indoor sampling results suggest that the EPA 10-05 risk screening level is exceeded at the East Satellite Building and Wells Fargo Bank. Lyle will furnish results after meeting with Bentley Mall owners. Permission to sample the indoor air at McDonalds has not been received after several inquiries. The local McDonalds is not a local franchise but controlled by the corporate headquarters. Lyle was advised that ADEC will assist in obtaining permission once the East Satellite Building and Wells Fargo results are received. It was agreed that as an interim measure existing HVAC systems should be evaluated and maintained at a positive pressure if possible.	Douglas Bauer
4/4/2005	Update or Other Action	Received by email latest indoor air sampling results. Tetrachloroethene (PCE) and trichloroethene (TCE) were detected in the indoor air at the Wells Fargo Bank and the East Satellite buildings on the Bentley Mall complex. Background levels (indoor and outdoor sources other than the vapor intrusion pathway) were not identified and measured. Therefore, the indoor air concentrations may reflect additional sources other than potential vapor intrusion. The range of PCE and TCE concentrations at the East Building were 33-35 µg/m³ and 0.58-6.8 µg/m³ respectively. At the Wells Fargo Building PCE and TCE concentrations ranged 170-200 µg/m³ and 1.5-1.6 µg/m³ respectively. For comparison, the target levels for the 10E-05 risk factor for PCE and TCE for residential buildings are 8.1 µg/m³ and 0.22 µg/m³ respectively. As an interim mitigation measure, the heating and ventilation systems at both buildings will be inspected and adjusted to maintain a positive pressure if possible. Alaska Resources and Environment (AR&E) has not obtained permission after several attempts to measure the indoor air at the McDonalds Restaurant west of the Wells Fargo Bank. Apparently the restaurant is no longer a local franchise and it is controlled by the corporate headquarters. The Department will assist AR&E in gaining access to the facility. Lindsay Smith was asked to calculate commercial building target levels using standard EPA commercial exposure frequency and exposure duration criteria. Due to her workload, Lindsay will not be able to provide the numbers until the end of April 2005.	Douglas Bauer

6/3/2008	Exposure Tracking Model Ranking	Initial ranking with ETM completed.	Ann Farris
7/23/2008	Update or Other Action	Staff received the 2007 Groundwater Monitoring Report and remediation status. The remediation system (AS/SVE) was installed in Sept 2006 and appears to be working. The concentrations in the source area are decreasing. Indoor air concentrations were measured in Wells Fargo and ESB building and were below commerical screening levels. HVAC systems operating during sampling. Asked consultant to identify houses within the plume area that have basements and this will be included in the 2008 report. The groundwater and indoor air sampling will continue. Some updates to the remediation system will continue and monitoring will continue. Appear to be in compliance with the ROD.	Ann Farris
7/10/2009	Update or Other Action	2008 Groundwater Monitoring and Indoor Air Quality Report was received. The results indicate improvement in the groundwater concentrations since the SVE system went online. The indoor air levels have not changed significantly, but remain below the commercial screening levels. Samples collected with HVAC operating. Houses with basements identified in the downgradient area that may be of concern for vapor intrusion. Correspondence made with contractor to discuss these results.	Ann Farris
7/24/2009	Update or Other Action	Staff contacted Wells Fargo regarding their plans for expansion at the Bentley Mall. Sandy Hoglund is primary contact.

Staff contacted consultants to set up meeting to discuss these results.	Ann Farris
9/16/2009	Meeting or Teleconference Held	Staff met with Ben Wells from ERG and Mike Hodges with CEECON regarding the site status and plans for upcoming year. Current landowner is Krauss Property Management (907) 456-3900. Ed Willis is still property manager, but working now for Krauss. Rawson has remained liable for the subsurface contamination. Wells Fargo and others are leasing the space. The SVE systems has been modified to include two new wells and tie in an existing vapor monitoring well. Treatment will be focused on the remaining hot spots along college road and the land between the SVE connex and Wells Fargo. Soil samples were collected by CEECON in this area and results will be presented in a report on the remediation system, expected by November. ERG plans to submit letter with this report with recommendations for system exit strategy and long-term monitoring strategy. Discussed need to address VI pathway in residential area.

10/7/2010	Meeting or Teleconference Held	IN september, the consultant, ERG, Inc., contacted me regarding their plans to try to shut down the SVE system and address our concerns about the vapor intrusion pathway in the residential neighborhood downgradiet. They since submitted a work plan to collect soil gas along the source area sewer line and Noyes Street (downgradient). The work plan was not satisfactory. The figures describing the sample locations were not legible, but the consultant was in the field doing the work already so they choose to proceed anyway. We discuss the approach they were taking and it appeared to be on the right track, however, I told them I could not guarantee we would accept the data. They expect results back in November and will submit a report.	Ann Farris
8/31/2011	Long Term Monitoring Established	Env. Resource Group (ERG) requested to turn off and remove the soil vapor extraction system. The site has not yet achieved cleanup levels, but the data indicate the system has removed a significant amount of the contamination and reached diminishing returns. ERG recommended monitored natural attenuation as the alternate cleanup plan to achieve final cleanup levels. Their proposed monitoring schedule is: • September 2011 • March/April and Sept/October 2012 and • March/April and Sept/October 2013 After these semi-annual events, ERG would like to move to a single annual event and ultimately even less frequent. Staff approved these changes based on review of the remediation system report, groundwater report, and passivee soil gas and indoor air survey reports received in 2011. An approval letter was sent today.	Ann Farris

Meeting or Teleconference Held

Telephone conversation with Lyle Gresehover with Alaska Resources and Environment: preliminary indoor sampling results suggest that the EPA 10-05 risk screening level is exceeded at the East Satellite Building and Wells Fargo Bank. Lyle will furnish results after meeting with Bentley Mall owners. Permission to sample the indoor air at McDonalds has not been received after several inquiries. The local McDonalds is not a local franchise but controlled by the corporate headquarters. Lyle was advised that ADEC will assist in obtaining permission once the East Satellite Building and Wells Fargo results are received. It was agreed that as an interim measure existing HVAC systems should be evaluated and maintained at a positive pressure if possible.

Douglas Bauer

4/4/2005

Update or Other Action

Received by email latest indoor air sampling results. Tetrachloroethene (PCE) and trichloroethene (TCE) were detected in the indoor air at the Wells Fargo Bank and the East Satellite buildings on the Bentley Mall complex. Background levels (indoor and outdoor sources other than the vapor intrusion pathway) were not identified and measured. Therefore, the indoor air concentrations may reflect additional sources other than potential vapor intrusion. The range of PCE and TCE concentrations at the East Building were 33-35 µg/m³ and 0.58-6.8 µg/m³ respectively. At the Wells Fargo Building PCE and TCE concentrations ranged 170-200 µg/m³ and 1.5-1.6 µg/m³ respectively. For comparison, the target levels for the 10E-05 risk factor for PCE and TCE for residential buildings are 8.1 µg/m³ and 0.22 µg/m³ respectively. As an interim mitigation measure, the heating and ventilation systems at both buildings will be inspected and adjusted to maintain a positive pressure if possible. Alaska Resources and Environment (AR&E) has not obtained permission after several attempts to measure the indoor air at the McDonalds Restaurant west of the Wells Fargo Bank. Apparently the restaurant is no longer a local franchise and it is controlled by the corporate headquarters. The Department will assist AR&E in gaining access to the facility. Lindsay Smith was asked to calculate commercial building target levels using standard EPA commercial exposure frequency and exposure duration criteria. Due to her workload, Lindsay will not be able to provide the numbers until the end of April 2005.

Meeting or Teleconference Held

IN september, the consultant, ERG, Inc., contacted me regarding their plans to try to shut down the SVE system and address our concerns about the vapor intrusion pathway in the residential neighborhood downgradiet. They since submitted a work plan to collect soil gas along the source area sewer line and Noyes Street (downgradient). The work plan was not satisfactory. The figures describing the sample locations were not legible, but the consultant was in the field doing the work already so they choose to proceed anyway. We discuss the approach they were taking and it appeared to be on the right track, however, I told them I could not guarantee we would accept the data. They expect results back in November and will submit a report.

Long Term Monitoring Established

Env. Resource Group (ERG) requested to turn off and remove the soil vapor extraction system. The site has not yet achieved cleanup levels, but the data indicate the system has removed a significant amount of the contamination and reached diminishing returns. ERG recommended monitored natural attenuation as the alternate cleanup plan to achieve final cleanup levels. Their proposed monitoring schedule is: • September 2011 • March/April and Sept/October 2012 and • March/April and Sept/October 2013 After these semi-annual events, ERG would like to move to a single annual event and ultimately even less frequent. Staff approved these changes based on review of the remediation system report, groundwater report, and passivee soil gas and indoor air survey reports received in 2011. An approval letter was sent today.

The solutions (cleaning and rinsing) will be captured and retained for F-002 hazardous waste disposal via the services of NRC Alaska, while the decontaminated SVE PVC piping will be disposed of as solid waste, no longer containing hazardous waste. ADEC understand this to be consistent with 40 CFR 265.45 Treatment Standards for Hazardous Debris.
