Problems/Comments

As part of a 2001 DEC/IPP compliance order by consent, the owner/operator repaired an oil/water separator and removed contaminated surface soil prior to paving the Truck Rack. Unresolved questions about residual soil contamination at the facility remained open until 2011 when the current property owner advanced trenches at the site to investigate the source of oil observed in the off-site the storm water ditch located below the property on Beach Road. Soil and water samples confirmed that the Oil/Water Separator (OWS) system was the source and DRO and VOCs were the primary contaminants of concern. In 2012 the owner decommissioned the faulty OWS system and advanced a broad series of soil borings to collect samples that characterize residual contamination in the subsurface. Sample analysis indicates levels of GRO and VOC compounds are at or below M2 MTG and the levels of DRO are between M2 MTG and human health criteria. Residual contamination exists in subsurface soil extending from an average depth of ten feet up to a layer of relatively clean overburden between two and five feet thick at the surface. Since VOC and SVOC compounds are not present in residual soil contamination above M2 MTG levels, any off-site migration to surface water by intermittent groundwater at the site is unlikely to violate 18 AAC 70 Water Quality Standard criteria.

Action Information

Action Date Action Description DEC Staff
4/28/1998 Site Added to Database Notification letter to DEC and US Coast Guard MSO states that fuel was found seeping from the ground in a ditch area below the southeast area of the Haines bulk fuel tank facility. A three foot by eight foot by three foot deep hole was dug to hold water and petroleum product seeping out of the ground. Sorbet material is used to collect excess oil from the surface of the water. With no discharge to the surface on the facility uphill of the seep, the source remains unknown. Bruce Wanstall
5/19/1998 Potentially Responsible Party/State Interest Letter ADEC sends letter with formal notice to the current operator of the bulk fuel facility in Haines that corrective action and site investigation was necessary for the interception trench along Beach Road and the source of a free product seep from subsurface soil under the bulk fuel tank farm property in Haines; owner and operator is Petro Marine. Anne Marie Palmieri
12/14/2000 Update or Other Action DEC Terminals and Tank Section site inspection in November 2000 found deficiencies needing upgrades; the Polyshield liner for the tank bottoms in the secondary containment areas, deteriorating paving and exposed piping at the truck rack, piping outside the containment with poor supports and/or chafe points and record-keeping on disposition of contaminated soils. Compliance actions by Petro Marine that are required by DEC regulation to be completed by 3/31/2000 include submitting plans to upgrade Polyshield liners on all tanks and upgrade the truck rack area to meet standards for impermeability and collision protection (bollards), ensure piping is serviced properly and marked if out-of-service and (ASAP) contact DEC Contaminated Sites regarding submitting a sampling plan for truck rack renovation and disposition of contaminated soil from prior tank farm renovations. Bruce Wanstall
6/6/2001 Document, Report, or Work plan Review - other DEC letter to Fred Gray with Delta Western - Haines approves Stockpile Sampling Report for the Petro Marine-Delta Western bulk fuel terminal II facility in Haines which was prepared by Smith Bayliss LeResche Inc. dated March 20, 2001. Two samples and a duplicate were collected from the seventy (70) cubic yard on-site stockpile and were analyzed for petroleum hydrocarbon fractions. The sample results meet the most stringent default soil cleanup levels and final placement of the tested soil is unrestricted but must not be within 100 feet distance from a water body or wetland or any environmentally sensitive area. Bruce Wanstall
5/17/2004 Update or Other Action Letter sent requesting that the owner perform a Site Assessment of the truck rack and barrel storage area spill sites before making upgrades in those areas of the facility previously agreed to in a COBC issued in 1995 by IPP. Anne Marie Palmieri

4/14/2009 Update or Other Action Oily water was observed in the Beach Road ditch-line in 1996 and 1998. DEC Site inspection of this tank farm facility took place in 1996 after release event identified as Petro Marine Services ID#096110120001. Plant supervisor Rich Kaloostian explained that during facility upgrade work to meet C-plan requirements, petroleum soil contamination was discovered near a set of line pumps. During the 1998 rebuild, sorbents were used to collect the oil, water was processed and the ditch was grubbed of oily soil. The ditch-line was backfilled with clean rock but no soil confirmation samples were collected to document effectiveness of the cleanup. Follow-up requests to Petro Marine and current owner/operator Delta Western for confirmation assessment have thus far gone unanswered. Bruce Wanstall
3/11/2011 Update or Other Action DEC requested by regular and electronic mail that Petro Marine Services prepare and submit for approval a workplan to assess those locations on the property where petroleum soil contamination cleanup was performed in 1998 under the Compliance Order by Consent issued by IPP for facility upgrades. Although contaminated soil was removed from the site and remediation of the off-site soil stockpile was later approved by DEC, confirmation sampling of clean soil at the limits of the removal excavation required in 18 AAC 75.341 was not performed and final reporting requirements in 18 AAC 75.380 was not performed. Despite the passage of time, it remains the responsibility of Petro Marine Services to meet those requirements. Bruce Wanstall
5/19/2011 Update or Other Action DEC met with Delta Western in teleconference to resolve a dispute in cleanup responsiblity between the former and current facility owners. After discussion of the history behind operation of an oil water separator and subsequent cleanup conducted in the 1990s, Delta Western agreed to submit site investigation work plan to DEC to determine the effectiveness of the historical cleanup of petroleum contamination at the facility. Bruce Wanstall
5/20/2011 Potentially Responsible Party/State Interest Letter DEC sent by letter to Delta Western today notice of State Interest that, in accordance with Alaska Statute 46.03.822 as owner/operator of the facility, Delta Western is a potential responsible party for the pollution incident and in accordance with AS 46.03.010 and AS 46.08.070 the State is required to recover all appropriate costs associated with providing oversight of investigation and cleanup activities relating to the pollution incident from said responsible party. DEC requested that Delta Western prepare and submit for approval a workplan to assess those locations on the property where petroleum soil contamination cleanup was performed in 1998 without confirmation sampling of clean soil at the limits of the removal excavation as required in 18 AAC 75.341. Delta Western verbally agreed to submit a work plan for an investigation. Bruce Wanstall
8/23/2011 Site Characterization Workplan Approved DEC has reviewed Workplan for Investigation of Former Petro Marine Tank Farm in Haines by Chilkat Environment dated August 9, 2010. The work plan objective, purpose, methodology, schedule and reporting design are in accordance with Title 18 Alaska Administrative Code 75.325 and 75.355 and the requests made by DEC to investigate contaminated soil and groundwater associated with historical release at the Delta Western Tank Farm contaminated site located at 12 Beach Road in Haines, Alaska. In accordance with Title 18 Alaska Administrative Code 75.320 the work plan is hereby approved. Bruce Wanstall
5/16/2012 Risk Assessment Workplan Approved DEC evaluated and sent approval by electronic mail for a ChemTrack Plan to transport contaminated soil from site activities at the Delta Western Tesoro gas station for storage in a temporary stockpile on the bulk fuel tank site. Bruce Wanstall
5/22/2012 Site Visit DEC met with Delta Western Fred Gray and ChemTrack staff Chris and Emery at the contaminated soil stockpile storage site on Haines Highway Cutoff. Contaminated soil from site activities at the gas station will be temporarily stockpiled at the tank farm. Bruce Wanstall
5/31/2012 Site Characterization Report Approved DEC sent approval by letter to Delta Western for: Former Petro Marine Tank Farm Haines, Site Characterization Report prepared by Chilkat Environmental Inc. The Report describes site activity in 2011 for the purpose of identifying sources of a historic petroleum release by investigating subsurface soil and groundwater for contamination and determining the potential for off-site migration. The Report concludes that weathered petroleum contamination is present in the subsurface in the vicinity of the truck rack, the rocky slope and the ditch on Front Street. The Report recommends that site controls be established bring a halt to the observed pathway by which petroleum contamination is migrating in groundwater from the on-site contaminated soil and in the discharge from the oil water separator. DEC agrees with the conclusions and recommendations in the Report that additional site characterization and abatement site activities are necessary. DEC requests that Delta Western submit an abatement work plan as soon as feasible. DEC agrees that the primary contaminants of concern are DRO and benzene. PAHs will be retained as a COC for the calculation of Water Quality Standards at the point of compliance. The site activity met the objectives of the project and review of the sample collection found that the number of representative samples collected is acceptable and the precision, accuracy and completeness of the resulting analytical data is sufficient to be used to support the decision making process. In accordance with 18 AAC 75.360, qualified person(s) used data collection and field screening methods consistent with DEC methodology in the approved site assessment work plan. The DEC laboratory report checklist submitted as an attachment is acceptable and the data meet field and laboratory report quality assurance criteria in Contaminated Sites Program guidance documents, therefore the Report is approved in accordance with 18 AAC 75.335(d). Bruce Wanstall
6/21/2012 Update or Other Action Address updated to reflect accurate site location. Kristin Thompson
7/6/2012 Site Characterization Workplan Approved DEC has evaluated the attached work plan and finds the proposed method of site investigation is an acceptable approach to meet the objectives of identifying the extent of historical contamination of soil and groundwater on the property and the adjacent roadside drainage.

3/29/2013 Document, Report, or Work plan Review - other The DEC evaluated Site Characterization Report, Former Petro Marine Tank Farm, Haines AK (Report), dated February, 2013. The ChemTrack Alaska Report documents environmental site characterization activities and source abatement for Delta Western in July, 2012. ChemTrack confirmed that leaking valves in the Oil-Water Separator system is the source of contamination found below the piping outfall in the ditch along Beach Road in 2000. Delta Western permanently disconnected and capped the line connecting the large storage tanks to the OWS holding tanks and pumped the three OWS holding tanks dry. ChemTrack utilized a Geoprobe 6620 DT direct-push machine and the DT 325 Sampling System advance borings at 8 locations from depths of 0 to 14 ft below the ground surface (BGS) in the yard area adjacent to the truck rack (Upper Sampling Area) and five soil borings at depths from 0 to 10 feet BGS in the ditch area along Beach Road (Lower Sampling Area). ChemTrack screened soil samples at two foot intervals and sent two samples from each boring with the highest readings for laboratory analysis. A steep bank spanning 15-20 vertical feet separates the Upper and Lower Sampling Areas at the inactive bulk fuel tank farm. Bruce Wanstall

4/29/2013 Site Visit DEC met with Fred Gray at the Tesoro Station; travel to the tank farm site to inspect the Beach Road ditch and discuss an interim soil removal plan. DEC gave verbal approval to Delta Western to proceed with the IRA and transport contaminated soil to the tank farm property and collect oily water into drums for assessment and treatment as needed. DEC will send a plan request letter to Delta Western Seattle and ChemTrack; ChemTrack will respond with a formal plan that reflects agreements made in the field during the site visit by DEC and Delta Western. Bruce Wanstall
4/30/2013 Update or Other Action DEC letter was sent by electronic and regular mail requesting that Delta Western submit a plan for approval that will schedule investigation and interim removal of contaminated needed for DOT to complete construction in the Beach Road Right of Way. The purpose of these site activities is to ensure that the pollution is contained and that the migration of contamination is not presenting a risk of exposure that could affect human health and safety or the environment. Bruce Wanstall
5/2/2013 Interim Removal Action Approved DEC reviewed and approved by letter sent by regular and electronic mail: Interim Removal Action Plan Delta Western Tank Farm Haines, Alaska (Plan), dated May, 2013. ChemTrack Alaska Inc. prepared the project specific plan to ensure that data quality objectives are met, and excavation and stockpile procedures are followed at the referenced site in accordance with State of Alaska DEC 18 Alaska Administrative Code 75 Articles 3 & 9, and the DEC Draft Field Sampling Guidance dated May 2010. The Plan objective, purpose, designs and methodology, sampling and reporting schedules are in accordance with Title 18 Alaska Administrative Code 75.325 and 75.355. The Plan responds appropriately to the request made by DEC to investigate and clean up contaminated soil and water associated with historical petroleum release at the referenced contaminated site in Haines, Alaska. In accordance with Title 18 Alaska Administrative Code 75.320 the IRA plan is hereby approved. Bruce Wanstall
9/20/2013 Site Characterization Report Approved DEC letter to Delta Western provides approval of the Petro Marine AKDOT Project Delta Western Tank Farm Haines Alaska (Report) dated June 2013. The Report by ChemTrack Alaska Inc. documents contaminated soil cleanup at the Delta Western Tank Farm Haines site in accordance with an Interim Removal Workplan approved by DEC letter to ChemTrack dated May 1, 2013. ChemTrack prepared the IR Plan to ensure that data quality objectives are met and excavation and stockpile procedures are followed in accordance regulation and DEC Guidance. The low levels of DRO contamination in remaining soil does not pose a significant risk of migration. Based on information currently available, DEC concludes that no additional investigation or cleanup is necessary in the Lower Sampling Area by the Beach Road warehouse dock at the referenced site. Bruce Wanstall
12/26/2013 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 79421 Truck Rack and Oil Water Separator. Bruce Wanstall
1/30/2014 Cleanup Complete Determination Issued Four interim removal actions of contaminated soil and two subsequent site investigations have demonstrated that residual petroleum contamination remaining at the site is in a discontinuous subsurface soil layer averaging between four and ten feet below the surface in the southeast quarter of the property in concentrations below human health based cleanup levels. An estimated volume of fifty cubic yards or less of the soil in this layer is in concentrations above migration to groundwater soil cleanup levels. This portion of the property is subject to institutional controls to ensure the contamination remains undisturbed unless a cleanup effort is initiated with prior approval from DEC. Since migration from soil in the shallow groundwater zone is minimal for lack of water, soil conditions are protective of off-site migration. Petroleum contaminated soil stockpiles have been transported off-site and remediated. This determination is in accordance with 18 AAC 75.380(d) and does not preclude DEC from requiring additional assessment and/or cleanup action if future information indicates that this site may pose an unacceptable risk to human health or the environment. Bruce Wanstall
1/31/2014 Update or Other Action Delta Western submitted to DEC an original signed agreement page that was provided as an attachment to the Cleanup Complete with Institutional Controls Letter issued by DEC January 30, 2014. Bruce Wanstall

5/4/2023 Update or Other Action Received email notification from Delta Western about above ground decommissioning activity at this location. Four of the ASTs and all portable containers used to store oil products have been removed from the site. Delta Western intends to submit a soil management work plan for review and approval. Evonne Reese
5/12/2023 Update or Other Action Received notification from Delta Western that there will be a utility line related excavation on the southeast part of the property which is expected to be 60 feet long by 24 inches deep. There is no known contamination in the area of the property. Update - the excavation was completed on 5/16/2023 and no contamination was encountered. Evonne Reese
6/5/2023 Document, Report, or Work plan Review - other Reviewed and provided comments on the May 10, 2023 Soil and Groundwater Contamination Management Work Plan for removal of contaminated soil remaining in the areas covered by the ICs. This work plan also includes three areas on the property with buried piping lines. All tanks and secondary containment have been removed from the property, including the fueling station 2,000-gallon tanks and dispensers. Evonne Reese
6/8/2023 Site Characterization Workplan Approved Reviewed the Soil and Groundwater Management Revision 1 work plan which addressed all DEC comments. This work plan is approved. Evonne Reese
7/19/2023 Document, Report, or Work plan Review - other Due to a much greater than expected volume of contaminated soil found during the recent investigation, work was halted so that a site characterization project could be planned. I reviewed a site characterization work plan on this date. Test pits will be placed to evaluate the vertical and lateral extent of the remaining contamination. Field screening and sampling results and recommendations for future work will be included in the final report. Evonne Reese
7/25/2023 Site Visit ADEC staff conducted a site visit on July 25, 2023 to observe site characterization work including the advancement of test pits, field screening, and analytical soil sampling. Rebekah Reams
10/26/2023 Update or Other Action Update on the summer 2023 field work - the open excavation pit is covered with an impermeable reinforced liner. Their personnel monitor the site on a frequent basis to ensure that the liner is working as intended. Additionally, a backup liner is staged across the street in the case of damage due to adverse weather that would require repair or replacement of the liner. Any water that collects in the excavation will need to be pumped out, field screened and most likely filtered prior to discharge when the field work resumes. Plans for additional excavation work in the spring are in the works. Evonne Reese
1/24/2024 Update or Other Action Received the Site Characterization Report on this date. Evonne Reese
3/1/2024 Institutional Control Update A cursory review of the Site Characterization Report was done on this date. Approval was provided to Delta Western to lay down an impermeable liner and backfill to close up the excavation pit. There is still remaining contamination in the soil therefore the institutional control requirements will remain in place. A thorough review of the report will be completed in the next week and a letter to Delta Western documenting the details will be issued. Evonne Reese
3/15/2024 Document, Report, or Work plan Review - other The January 2024 Site Characterization Report was reviewed on this date. This report included the details of the June and July 2023 investigation which identified much more contaminated soil than expected. One hundred and twenty-eight cubic yards of contaminated soil were excavated from the area of the property where the ICs apply. This soil was screened/sampled, placed into supersacks, and transported to Bicknell, Inc. in Juneau for treatment. An unknown volume of contaminated soil remains in the ground in this area of the property. Field screening and laboratory analyses documented other areas of soil contamination in the northeast and southwest portions of the property in addition to the excavation area which is covered by the ICs. These areas were covered with the tank farm containment liner when the property operated as a tank farm. This new information indicates that areas on the property not included in the 2014 Cleanup Complete – ICs decision site may present an unacceptable risk due to the presence of contamination in the soil. Evonne Reese
4/10/2024 Site Reopened The information provided in the 2024 Site Characterization documented the investigation of the known areas of contamination. This assessment also documented contamination on areas on the property which have not been delineated and were not included in the 2014 Cleanup Complete Determination – ICs decision. For this reason, further characterization will be required and the site record for the Delta Western Tank Farm II Haines will be changed to Active status in the DEC’s site record. Evonne Reese
4/18/2024 Update or Other Action Provided approval to place a liner and backfill the excavation onsite. I also provided approval to place some fill in the former secondary containment areas in order to provide a protective barrier. Once the fill is laid out, Delta Western will provide us with a diagram of the locations that the fill was placed. Evonne Reese
