Problems/Comments

Surface and subsurface soil have been contaminated by the release of diesel fuel from a leaking heating oil tank and from bulk fuel piping to the dispenser. Limited investigation and cleanup have been completed but additional soil and groundwater investigation and an active cleanup remedy are needed. An active drinking water well on the adjacent lease property is a potential exposure pathway for off-site migration of subsurface petroleum contamination. A DEC site inspection in May 2012 observed oil stains on the surface inside the hanger building from an open doorway at the back of the building facing north.

8/15/2006	Update or Other Action	Letter sent to the RP requesting that the source of the oil spill be determined, ground water investigation be conducted and evaluate distance to drinking water wells in the area with possible sampling and analysis for petroleum contamination.	Bruce Wanstall
1/5/2007	Potentially Responsible Party/State Interest Letter	DEC sent a PRP letter to LAB Flying Service at the address of record in Haines (PO Box 272) providing notice that Alaska Statute Title 46 authorizes the State to respond to this pollution incident and to take appropriate action to minimize damages to human health, safety and welfare or to the environment. Under Title 46, the owner or operator may be held financially responsible for any actions taken by the State. LAB Flying Service has undertaken response actions approved by the Department under Title 18 Alaska Administrative Code (AAC) 75.300 - .396, and the adequacy of those actions is being evaluated by Bruce Wanstall, the Project Manager for this pollution incident. Response actions are adequate if they are in accord with state and federal law, including 18 AAC 75. If LAB Flying Service continues taking adequate actions, State action will be limited to approving cleanup plans, monitoring the progress of cleanup activities and providing guidance as necessary. Alaska Statute 46.08.070 requires that recovery be sought for certain costs, including oversight activities, incurred by the State in responding to pollution incidents. State expenditures may include the direct costs of staff time and indirect State overhead costs, as well as contractual and material costs. State staff time includes all time spent on activities related to the incident, including site visits, response and report reviews, telephone conversations, meetings, legal services, and interest.	Bruce Wanstall
8/14/2007	Update or Other Action	Contacted LAB by telephone to request a meeting with Mr. Bennet to walk through the oil spill site at the LAB Hanger lease lot 8 Block 1; ADEC is concerned that oil from the spill may be impacting groundwater at the airport and affected the drinking water well at the terminal building operated by Wings.	Bruce Wanstall
8/15/2007	Exposure Tracking Model Ranking	Ground and surface water ingestion are the pathways with high potential exposure risk based on site assessment data from surface soil samples that were collected after contaminated soil was removed from beneath piping and next to the hanger foundation. Groundwater investigation is requested from the leaseholder LAB but has not been completed.	Bruce Wanstall
8/21/2007	Update or Other Action	ADEC arranged a meeting with the facility owner to inspect the LAB Flying Service Hanger at the Haines Airport and discuss site assessment of ground water at the State-owned lease property. The owner was unexpectedly unable to attend the site meeting; ADEC observed free product leaking from a heating oil tank filter causing staining of a 10 square foot area of soil behind the hanger. The spill site is the same site where limited contaminated soil cleanup occurred in 2002. LAB has reportedly halted the release and will provide photographic evidence of temporary cleanup to ADEC until the owner is able to return and make arrangements for the requested site assessment.	Bruce Wanstall
8/27/2007	Spill Transferred from Prevention Preparedness and Response Program	Spill transferred by PERP staff Lester Leatherberry. Spill Number 07119923301; Spill Date = 8/21/07; Substance = Diesel; Quantity = Unknown.	Mitzi Read

The cleanup process regulations and State Interest notification of facility operator cleanup liability were also included in the letter mailed certified return receipt to the responsible party, LAB Flying Service, and copied to the property lease manager at ADOT&PF.	Bruce Wanstall
8/10/2009	Document, Report, or Work plan Review - other	ADEC evaluated the 2008 laboratory data report for the soil and water samples collected at the spill site behind the airport hanger facility. Discrepancies and quality assurance failures with sample analysis are accounted for in the Report by Nortech. Benzene, toluene, ethylbenzene and total xylene (BTEX) compound concentrations in soil were below laboratory instrument reporting limits. Diesel range (DRO) hydrocarbon fraction concentration in soil at the leaking above ground tank was 8,680 mg/kg. Residual range (RRO) hydrocarbon fraction concentration in soil was 4,470 milligrams per kilogram (mg/kg). Benzene and toluene concentrations in ground water were below laboratory instrument reporting limits in each of three ground water samples analyzed; ethylbenzene and total xylenes were above instrument detection in low concentrations. DRO concentration in ground water in MW01 reached 13.2 mg/L. In MW02 and MW03, DRO concentrations were 0.5 and 0.6 mg/L respectively.	Bruce Wanstall
8/12/2009	Conceptual Site Model Submitted	ADEC update to the CSM has determined that contaminated media at the oil spill site includes surface soil, subsurface soil and ground water. Completed exposure pathways needing evaluation and monitoring include inhalation of outdoor air vapors, ingestion of soil and ground water, and dermal contact with soil for current and future exposure risk. The ratio of RRO concentrations compared with corresponding DRO concentrations in soil and water samples are unusual for samples from a heating oil spill source. The consistent DRO to RRO ratio represents a possible data gap in the conceptual site model source identification.	Bruce Wanstall
8/13/2009	Document, Report, or Work plan Review - other	ADEC reviewed the limited site investigation that found DRO concentration in shallow soil and groundwater exceed cleanup levels near a leaking above ground heating oil tank that is scheduled for replacement. Soil contamination exists in the soil directly under the spill area, affecting an estimated ten to twenty cubic yards of material adjacent to the foundation in back of the hanger. In 2002, contaminated material was removed by hand from this same area to the extent feasible without undermining the building or supports for above-ground steel fuel lines for the bulk aviation fuel tank. In 2008, LAB removed several cubic yards of the most contaminated material under the leaking tank and stored it in fish totes on the property. A schedule for additional investigation and in-situ remedial treatment is recommended.	Bruce Wanstall
1/4/2011	Exposure Tracking Model Ranking	A new updated ranking with ETM has been completed for source area 74837 Above Ground Storage Tank.	Bruce Wanstall
4/2/2012	Exposure Tracking Model Ranking	A new updated ranking with ETM has been completed for source area 74837 Above Ground Storage Tank. In 2008 DEC determined that the sampling and tests the Wings Terminal tap water meet drinking water standards for petroleum compounds but additional testing is needed. Contaminated soil is still stored on the site; status unknown.	Bruce Wanstall
5/22/2012	Site Visit	DEC site visit: Heavy alder growth that was previously observed on the back of the property had been cut down and removed. An overpack drum that reportedly contains contaminated soil and a empty heating oil tank were observed. A shallow hole located at the spill site was dry; soil in the hole had a strong fuel odor. Stand pipe or monitor well could not be located on the open portion of the property adjacent to the fenced aiport grounds. The tap at the Wings Terminal was still operable with signage stating: DO NOT DRINK THE WATER in English only.	Bruce Wanstall
8/23/2012	Update or Other Action	DEC letter was sent certified by regular mail to the owner/operator of the LAB Flying Service Hanger in Haines, Alaska requesting a plan be submitted for approval that will schedule soil and groundwater investigation of contamination from a heating oil spill on the property. 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
10/10/2012	Update or Other Action	DEC evaluated the record of correspondence and the DEC letter sent certified return receipt in August 2012 that was signed for by Bennett. The letter requested the RP declare intent to comply with DEC request for additional site investigation within 30 days. DEC placed phone call to a listed number in Haines for Layton Bennett; received a message stating the number has been disconnected. Placed a call using a second number for Bennett in Haines; no answer and no message system available.	Bruce Wanstall
1/23/2013	Update or Other Action	DEC contacted a representative of LAB Flying Service and conveyed that soil and groundwater petroleum contamination is still present on the lease property at the Haines Airport. As a result after five years it is time to collect a sample the tap water from the well on the neighboring lease property to test for petroleum contamination. When structures on the LAB property are removed and underlying soil is accessible a site investigation can be completed to determine the extent of contamination and if the historical limited soil cleanup was effective.	Bruce Wanstall
1/30/2013	Update or Other Action	Telephone discussion will Bill Joiner yesterday and Eric Bennett today regarding tap water sampling at the Wings Terminal at the Haines Airport. Prepare an email with last letter sent to owner Layton Bennett attached with brief instructions reagarding the DEC request for site investigation of remaining petroleum contamination on the State-owned lease property.	Bruce Wanstall
4/29/2013	Site Visit	While waiting for a return flight to Juneau DEC performed a safe view site visit to inspect the condition of the LAB Hanger at the Haines Airport. The hanger appeared intact and oil stains were observed next to an upright 55-gallon drum with unknown contents probably waste oil. The drinking water tap in the Wings Terminal Building was functional and signage warned to not drink the water.	Bruce Wanstall
5/8/2013	Update or Other Action	DEC communicated to Joiner Engineering, consultant for LAB Flying Service, that the laboratory analysis for BTEX compounds by EPA 8015 and DRO/RRO by Alaska Methods 102 and 103 on a sample of Wings Terminal tap water is adequate to determine if petroleum contamination is migrating in groundwater from the LAB Flying Service Hanger property. Joiner plans to collect a sample in May of 2013.	Bruce Wanstall
7/11/2013	Document, Report, or Work plan Review - other	DEC performed a quality assurance evaluation of the laboratory report submitted by Joiner Engineering for analysis of a sample of tap water at the Wings Terminal adjacent to the LAB Flying Service Hanger at the Haines Airport. No petroleum constituents were detected in the analysis. The purpose of testing water from the well is to characterize groundwater for petroleum compounds that may have been transmitted from contaminated soil that remains on the LAB FS Hanger property. The objective of the testing is to ensure the protection of human health, safety and the environment from exposure to petroleum contamination. DEC sent an email message to Eric Bennett with sample and laboratory report approval copied to DOT Aviation Leasing (Lyn Campbell) and Joiner Engineering.	Bruce Wanstall
5/27/2014	Enforcement Action	DEC is providing Layton Bennett, owner of LAB Flying Service, with a Notice of Violation regarding the release of hazardous substances pollution on the referenced property leased from the State of Alaska at the Haines Airport.

Update or Other Action

DEC contacted a representative of LAB Flying Service and conveyed that soil and groundwater petroleum contamination is still present on the lease property at the Haines Airport. As a result after five years it is time to collect a sample the tap water from the well on the neighboring lease property to test for petroleum contamination. When structures on the LAB property are removed and underlying soil is accessible a site investigation can be completed to determine the extent of contamination and if the historical limited soil cleanup was effective.

Site Visit

While waiting for a return flight to Juneau DEC performed a safe view site visit to inspect the condition of the LAB Hanger at the Haines Airport. The hanger appeared intact and oil stains were observed next to an upright 55-gallon drum with unknown contents probably waste oil. The drinking water tap in the Wings Terminal Building was functional and signage warned to not drink the water.

Update or Other Action

DEC communicated to Joiner Engineering, consultant for LAB Flying Service, that the laboratory analysis for BTEX compounds by EPA 8015 and DRO/RRO by Alaska Methods 102 and 103 on a sample of Wings Terminal tap water is adequate to determine if petroleum contamination is migrating in groundwater from the LAB Flying Service Hanger property. Joiner plans to collect a sample in May of 2013.

Document, Report, or Work plan Review - other

DEC performed a quality assurance evaluation of the laboratory report submitted by Joiner Engineering for analysis of a sample of tap water at the Wings Terminal adjacent to the LAB Flying Service Hanger at the Haines Airport. No petroleum constituents were detected in the analysis. The purpose of testing water from the well is to characterize groundwater for petroleum compounds that may have been transmitted from contaminated soil that remains on the LAB FS Hanger property. The objective of the testing is to ensure the protection of human health, safety and the environment from exposure to petroleum contamination. DEC sent an email message to Eric Bennett with sample and laboratory report approval copied to DOT Aviation Leasing (Lyn Campbell) and Joiner Engineering.

Document, Report, or Work plan Review - other

DEC has evaluated the Nortech Site Assessment Report on carrying out the approved sampling and analysis plan at the LAB Flying Service Hanger site on Lot 8 at the Haines Airport. A copy of the approval letter, with comments and requests, was circulated by email and was sent by regular mail to the Nortech Juneau office and to Layton Bennett at his address in Renton, WA. Based on the information provided in the Report, the DEC concurs with conclusions in the Report that contamination of the hanger lease lots is generally well defined. DEC looks forward to working with LAB on a plan for mechanical recovery of contaminated soil to the maximum extent with remediation locally, if feasible. In the meantime, DEC requested additional site investigation under the hanger and aircraft apron and chemical analysis of the tap water at the passenger terminal for petroleum contamination. Due to evidence of a release of aviation gasoline, DEC requested evaluation of total metals contamination in the GRO soil contamination plume.
