4/19/2007 Exposure Tracking Model Ranking Initial and final ranking completed. Deborah Williams
4/20/2007 Institutional Control Record Established The conditions of the closure are the following: 1. In accordance with 18 AAC 75.325(i), ADEC approval must be obtained prior to transport and/or disposal of soil or groundwater from this site. 2. A deed notice (Notice of Environmental Contamination) shall be filed with the State Recorder’s Office regarding the location of residual contamination remaining at the site. The residual contamination will also be noted in ADEC’s Contaminated Sites Database. 3. No groundwater wells shall be installed on the property without the prior review and approval of ADEC. 4. The long-term groundwater monitoring plan consists of sampling ESL–MW 3, ESL-MW8A, ANI-MW3 in 2007 for VOCs and every other year until the groundwater meets ADEC Table C cleanup levels. Deborah Williams
4/20/2007 Conditional Closure Approved ADEC gave a conditional closure determination for this site. Deborah Williams
7/24/2007 Document, Report, or Work plan Review - other ADEC received the Groundwater Sampling report for the Westours Maintenance Facility. On June 5, 2007, Hart Crowser sampled monitoring wells ANI-MW3, ESL-MW03, and ESL-MW8A. Groundwater was measured at approximately 11.5 to 13.5 feet bgs. The groundwater samples were analyzed for VOCs. All the ananlyticals showed volatile organic compounds below ADEC cleanup levels except for ESL-MW8A which had TCE at 0.024 mg/L. The previous sampling from that well in August of 2005 had TCE at 0.00097 mg/L. (This action was copied from the actions in the CS site at this same location under the file number 102.38.018 since this report covers both LUST and CS parts of this site. (Originally entered by Deb Williams) Evonne Reese
10/13/2010 Document, Report, or Work plan Review - other DEC received from Oasis the well decommissioning report for wells: ESL-MW1A, ESL-MW-2, ESL-MW4, ESL-MW5, ESL-MW7, ESL-MW8, ANI-MW1, ANI-MW2, ANI-MW4, CH-MW1, CH-MW2, CH-MW3, CH-MW4, CH-MW5, CH-MW-6, and CH-MW7. Well rehabilitation was conducted for the wells included that are being sampled as part of the institutional controls: ANI-MW3, ESL-MW3, and ESL-MW-8A. (This action was originally entered by Tamara Cardona-Marek under a CS site on the same property called Westours Bus Maintenance Facility (102.38.018 ). The CS and LUST site have the same groundwater monitoring requirements.) Evonne Reese
3/31/2011 Institutional Control Compliance Review IC review conducted, added tickler reminder, changed project manager to IC Unit, and added periodic reporting requirement. Evonne Reese
9/9/2011 Document, Report, or Work plan Review - other DEC received and reviewed from Oasis the 2011 Groundwater Sampling Report. Results are similar to the previous event. TCE exceeded ADEC cleanup levels in well ESL-MW-8A with 11ug/L.(Original action entry was in the Westours site 102.38.018 made by Tamara Cardona-Marek. Both sites have the same groundwater monitoring requirements since they are on the same property.) Evonne Reese
10/10/2012 Leaking Underground Storage Tank Release Confirmed - Petroleum LUST site created in CSP database for source area Piping joint, 79342 Tamara Cardona-Marek
10/10/2012 Site Reopened Removal of a 12,000 gallon diesel tank revealed a small amount of contamination in the piping trench near a joint. Contamination was found at a depth of 1 foot. It is unknown if contamination is the result of a leaky joint or surface spills. It is also unclear if contamination extends any deeper. Evonne Reese
10/10/2012 Exposure Tracking Model Ranking Initial ranking with ETM completed for source area id: 79342 name: Piping joint Tamara Cardona-Marek
3/21/2013 Document, Report, or Work plan Review - other DEC reviewed the 2012 additional UST closure site assessment report from Restoration Science and Engineering, LLC. Four soil samples were field screened with PID and sent to SGS for analysis. The sample with the highest PID reading was analyzed for DRO, GRO, and BTEX. A second sample was also analyzed. Both samples contained contaminants at concentrations below cleanup levels. Robert Burgess
6/12/2013 Update or Other Action Site transferred to Robert Burgess. Janice Wiegers
6/21/2013 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 79342 Piping joint. Robert Burgess
6/27/2013 Cleanup Complete Determination Issued Cleanup complete with institutional controls finalized; letter sent to Holland America Princess. ICs include reporting on land use, ADEC approval for excavation, transport, and characterization of soil, and previous ICs will still apply. Robert Burgess
8/9/2013 Update or Other Action DEC received the signed IC agreement from Holland America Princess Robert Burgess
8/9/2013 Update or Other Action Staff name changed from Robert Burgess to IC Unit. Evonne Reese
12/20/2013 Institutional Control Compliance Review IC review conducted. This site is being managed jointly with 102.38.018. Evonne Reese
7/30/2014 Institutional Control Update An IC reminder letter was issued to the responsible party on this date. Kristin Thompson
9/4/2014 Update or Other Action There has been a change of property ownership on this site, but Holland America will remain the responsible party and contact for the ongoing institutional controls. Affiliate information has been updated with the change. Evonne Reese
9/4/2014 Document, Report, or Work plan Review - other ADEC staff reviewed Reson Alaska's 2012 Groundwater Monitoring report for the Westours Bus Maintenance Facility. Monitoring wells ANI-MW3, ESL-MW-3, and ESL-MW-8A were sampled for VOCs and one duplicate sample was collected from well ESL-MW-8A. Groundwater was measured at approximately 10.7 to 13.4 feet bgs. Only the TCE concentration was above ADEC cleanup levels in well ESL-MW-8A (0.0133 mg/L) and the duplicate sample (0.0145 mg/L), which is generally consistent with previous monitoring events. All other VOC concentrations were below ADEC cleanup levels. Kristin Thompson
12/15/2014 Document, Report, or Work plan Review - other ADEC staff reviewed Rescon Alaska's 2014 Groundwater Monitoring Report for the Westours Bus Maintenance Facility. Monitoring wells ANI-MW-3, ESL-MW-3, and ESL-MW-8A were sampled for VOCs and one duplicate sample was collected from well ANI-MW-3. Only the TCE concentration was above ADEC cleanup levels in well ESL-MW-8A (0.012 mg/L) which is generally consistent with previous monitoring events. All other VOC concentrations were below ADEC cleanup levels. The next groundwater monitoring event will occur on the biennial schedule, in 2016 and will include a monitored natural attenuation analysis. Kristin Thompson
1/30/2017 Document, Report, or Work plan Review - other ADEC staff reviewed Rescon Alaska's 2016 Groundwater Monitoring Report for the Westours Bus Maintenance Facility. Monitoring wells ANI-MW-3, ESL-MW-3, and ESL-MW-8A were sampled for VOCs and one duplicate sample was collected from well ESL-MW-8A. The TCE concentration was only above ADEC cleanup levels in well ESL-MW-8A (13 ug/L) which is very consistent with previous monitoring events. The TCE concentration in well ESL-MW-8A has effectively remained unchanged over the last seven years. Rescon recommends implementing an enhanced attenuation (EA) amendment to accelerate reduction of the TCE contamination. In order to move forward, the ADEC will require a brief work plan to be submitted with further details on what Rescon proposes to add to enhance natural attenuation. The ADEC will need to evaluate whether the levels of reagent being proposed for injection are safe and would not produce excessive gas. Therefore, ADEC has requested Rescon provide such a work plan prior to the next sampling event, and with enough time for review and approval of the methodology. Kristin Thompson
1/30/2017 Institutional Control Compliance Review IC compliance review conducted. Kristin Thompson
12/21/2018 Document, Report, or Work plan Review - other ADEC staff reviewed Rescon Alaska's 2018 Groundwater Monitoring Report for the Westours Bus Maintenance Facility. Monitoring wells ANI-MW-3, ESL-MW-3, and ESL-MW-8A were sampled for VOCs and one duplicate sample was collected from well ESL-MW-8A. From these results the TCE concentration was above ADEC cleanup levels in well ESL-MW-8A (9.22 ug/L) which is consistent with previous monitoring events. All other VOCs concentrations were either below cleanup levels or non-detect. The TCE concentration in well ESL-MW-8A has effectively remained unchanged over the last seven years and has varied between 9 and 13 ug/L. The reporting findings documented that due to the shallow gradient in the area of this site, the degradation process of the TCE will be slow. Another round of groundwater monitoring is planned Evonne Reese
