Observation and Confirmation Sampling at ASTS at (Building 992) Fueling Point Facility #788, 92600 Otter Lake Road.
Tutka, llC (Tulka) was contracted by Granite Petroleum, Inc., lo provide an ADEC qualified
person to observe, collect confirmation soil samples and complete a report on the removal of
above grade storage tank (AST) at the military refueling facility located at 92600 Otter Lake
Road, Joint Base Elmendorf-Richardson (JBER). Alaska. During the period August 8th to
August 9th 2012, a Tutka representative was on site to observe the removal of two ASTs. and
associated piping.
Late in the day on August 8th, 2012. a large excavator was used to remove the asphalt covering
the buried fuel line running from the ASTs to the underground storage tanks (USTs) and pull out
the line. See Figure 1. The line consisted of a two inch flexible hose within a four-inch semirigid plastic pipe. There were no obvious breaks or release along the fuel line observed.
The north end of this line was terminated in a sump. There was free liquid in the sump which was
soaked up with absorbent pads. There was a hydrocarbon odor around the sump. This sump
was excavated and samples of the soli beneath It were taken for both field screening (heated
head space analysis) and analytical laboratory analysis. A sample (FTR269A-009) was
collected out of the excavator bucket.
A third aliquot of soil (taken from the excavator bucket) was placed into a plastic, quart-Sized sealable baggie for testing of the headspace vapors with a photoionization detector (PID).
The screening sample read over 799ppm with the PIO. For health and safety reasons work was not allowed in this area (around the sump) due to the high PID reading.
Based on contract and base policy we were not allowed to work around the area of high
contamination. Reportedly base personnel later came back to this site and excavated
contaminated soil and replaced it with clean fill, but this was not observed by Tutka.
All samples were submitted for gasoline range organics (GRO). diesel and residual range organics
(DRO/RRO). benzene, toluene, ethylbenzene and xylenes (BTEX) analysis by methods AK101,
AK1021103 and SWS260B, respectively. One sample (FTR269A-009) was also collected for
polycyclic aromatic hydrocarbons analysis by method SWS270D SIM.
ADEC data review checklists were completed by a Qualified person for each chain of custody for this project and are included in the appendices to this report. The data reviews show that the analytical results may be used with confidence to compare the collected site soil samples with the applicable cleanup concentrations.
Sample ID FTR269A-009 had GRO at 491 mg/kg (300 mg/kg MGW clenaup level), DRO at 4,000 mg/kg (250 mg/kg MGW cleanup level), benzene at 96.3 ug/kg (25 ug/kg MGW cleanup level)

Site Assessment of (Building 992) Fueling Point Facility #788, 92600 Otter Lake Road received.
Tutka, LLC (Tutka) was contracted by Granite Petroleum, Inc., to provide an ACEC qualified
person to observe, collect confirmation soil samples and complete the ACEC Storage Tank
Program Site Assessment & Release Investigation Summary Form for the underground storage
tank (UST) removal at the military refueling facility located at 92600 Otter Lake Road, Joint
Base Elmendorf-Richardson (JBER), Alaska. Curing the period August 7th to August ~ 2012, a
Tutka representative was on site to observe the removal of two USTs, associated piping and
four dispensing islands.
Work began on August -('1,2012. The two USTs, both 10,000 gallon tanks, were numbered 201
- used to store diesel fuel, and 202 - used to store gasoline. The USTs had been pumped out
by others and dry ice was placed into the tanks to inert them. When the certified UST
decommissioner supervisor (Scott Yashus) indicated it was safe the material above the USTs
was removed. Tank 202 was removed first. It was an Anchorage Tank "StiPz"-10,OOO gallon,
double walled 1/4 inch steel tank. There was no visible rust or pits on the exterior of the tank.
Next, tank 201 was removed from the ground. It was the same type and in the same condition
as tank 202. See Photograph 1 in appendix A. The excavation where the two USTs were was
measured; 32 feet by 48 feet by 14 feet deep, for a bottom surface area of 1536 square feet.
The location of these samples is shown on figure 1. A total of eight samples were collected beneath the former location of the USTs. A duplicate sample was collected at the location FTR269A006 and was labeled FTR269A007. At each location a sample was collected out of the excavator bucket.
All samples were submitted for gasoline range organics (GRO), diesel and residual range organics (OROIRRO), benzene, toluene, ethyl benzene and xylenes (BTEX) analysis by methods AK101, AK10211 03 and SW8260B, respectively. One sample was also collected for polycyclic aromatic hydrocarbons analysis by method SW82700 SIM.
Sample ID FTR269A-003 detected benzene at 28.4 ug/kg just above the 25 ug/kg migration to groundwater cleanup level.
Based on the results of the soil sample laboratory analyses, and visual observations during the
UST and piping removal that there is not hydrocarbon contamination present in the soil at the
subject property that is above the most stringent ADEC cleanup levels (18 AAC 75.340, Table
82. Method Two, under 4O-inch (precipitation) Zone, Migration to groundwater) for GRO,
DRO/RRO, toluene, and total xylenes, except for one sample (FTR269A-003) that had a benzene level of 28.4 ~g/Kg which is slightly above the cleanup level of 25 ug/Kg . |

Document, Report, or Work plan Review - other |
Staff provided comments on the (building 992) Refueling Facility confirmation sampling of ASTs & USTs site assessment.
General Comments Missing from the cover page is: Name & signature of “qualified person ” responsible for collecting samples. Name & signature of “qualified person” responsible for interpreting the data. Name & signature of “qualified person” responsible for reporting the data.
Introduction Missing from the text is any history of use of the ASTs, information on the type of product(s) that were stored, used in the ASTs other than what is presented on the Figure 1.
ADEC requests JBER elaborate on the history of the ASTs (Tank 1 & Tank 2) & whether or not the leaded gasoline may have been stored during use of the ASTs. ADEC requests JBER name the “qualified person(s)” that observed the AST(s) removal, collected confirmation soil sampling & completed the report. State why the ASTs were being removed & any recent tightness testing results from the tank & associated piping.
Field Observation & Soil Sampling The text states: “Based on contract & base policy we were not allowed to work around the area of high contamination.”
ADEC requests JBER elaborate on what contract is being referred to & what base policy does not allow the environmental contractor with the “qualified persons” to sample or work around the area of “high contamination”. Also it goes on to state that reportedly base personnel later came back to this site & excavated soil & replaced it with clean fill but this was not observed by Tutka. ADEC requests JBER elaborate which base personnel removed this soil with “high contamination” & under what authority or ADEC approved work plan the work was conducted & whether confirmation samples were taken in accordance with ADEC’s draft Field Sampling Guidance (May 2010).
ADEC has record of a “Request to Transport” – Multiple Sites dated August 15, 2012 which referred to four sites including FTR269A Demolition of former Building 992 & Fuel Facility. The request stated: Source of contamination at this site is a fuel pump sump that ruptured during removal releasing less than a gallon of fuel that drained from the pump. Soil will be excavated & placed in a SuperSack® for disposal at ASR.
The request states in Comments: “Excavation sites will be field screened to determine limits of excavation & confirmation soil samples will be collected from each site. Source of contamination at FTR269A (former Bldg 992 fuel site) is a fuel pump sump that ruptured during removal releasing less than a gallon of fuel.”
No confirmation samples are mentioned in the document. In accordance with the 1994 Environmental Restoration Agreement, ADEC has determined that additional contamination assessment is required due to lack of field screening & laboratory analysis results from required confirmation samples after the removal of contaminated soil from the ruptured fuel pump sump.
August 9th, 2012, two samples were collected along the pipe run & screening samples were collocated & afterwards they were checked with the PID & had a reading of zero. Field notes were not provided with the document for ADEC’s review.
ADEC’s draft Field Sampling Guidance (May 2010) states:
Conduct field screening & confirmation sampling at aboveground & underground
storage tank locations as follows:
Tank Area:
• Below the tank, as per Table 2B.
• Adjacent to & below all fill & vent pipes.
• Excavation sidewalls, as per Table 2B.
• For an in-place assessment, no more than five (5) feet from the tank.
• Other areas of suspected contamination.
Piping Run & Dispensers:
• Within two (2) feet below piping joints, elbows, connections, &
damaged piping components; if these locations are unknown then
screening must occur within two (2) feet below original level of piping at
a minimum frequency of one field screening sample for every ten (10) foot
length of piping.
• Adjacent to & within two (2) feet below all dispensers.
• Other areas of suspected contamination.
Absence of positive field screening results or those field screening results below an arbitrary threshold cannot be used alone as justification for not taking the associated number of laboratory analytical samples.
Based on the information provided, field screening was not done at the elbows & it is unknown whether or not that the two samples that were field screened, sampled & re-field screened were in areas of known connections or damaged piping components or visible contamination. Field screening & sampling may or may not have occurred within a two (2) feet interval BELOW the original level of the piping joints &/or connections, however the text does not state this & only states screening & samples were collected at the “east end” & the “west end” of the pipe run. |

Site Characterization For Removal of USTs Building 992 Fueling Point Facility #788 92600 Otter Lake Road, JBER, AK Prepared for Granite Petroleum, Inc by Tutka LLC.
Granite Petroleum, Inc., contracted Tutka, LLC (Tutka) to provide an ADEC qualified person to
observe, collect confirmation soil samples, and complete the ADEC Storage Tank Program Site
Assessment & Release Investigation Summary Form for removal of underground storage tanks
(UST) at former Building 992, a military refueling facility located at 92600 Otter Lake Road, Joint Base Elmendorf-Richardson (JBER), Alaska.
The military refueling facility at this site is located on the eastern side of Otter Lake Road between Circle Drive and Warehouse Street. The site is listed as ADEC Facility #788 with two USTs, each 10,000 gallons. The USTs were used to store diesel (Tank #201 with Compliance Tag #0967) and gasoline (Tank #202 with Compliance Tag #0968). Based on observation and results of soil samples analysis, limited petroleum contamination was identified during the UST removal.
All samples were received and analyzed by SGS in Anchorage, Alaska. Complete copies of the
analytical data results are included in Appendix D. ADEC data review checklists were completed by a qualified person for all samples collected for this project and are included in Appendix E to this report. The data reviews show that the analytical results may be used with confidence to compare the collected site soil samples with the applicable cleanup concentrations. The chemical Data Quality assurance summary is included as the next section.
Results for the samples are presented in Table 1 below. The analytical results were compared
to the most stringent ADEC cleanup levels (18 AAC 75.340, Table B2. Method Two, Under 40-
inch (precipitation) Zone, Migration to Groundwater) for GRO, DRO/RRO, benzene, ethylbenzene, toluene, and total xylenes and none of the results exceeded them except for benzene at FTR269A003. The analysis for benzene at that location was 28.4 µg/Kg with the applicable cleanup level of 25 µg/Kg.
In addition to the GRO, DRO/RRO and BTEX analysis, one sample location, FTR269A-001,
was also sampled and analyzed for polycyclic aromatic hydrocarbons analysis by method
SW8270D SIM, with results being all non-detected. |
