Problems/Comments

This site consists of the removal of a 500-gallon waste oil UST Facility ID 1448 Tank 2. The UST was used to store waste oil from an oil/water separator housed inside the building that had been removed by a MOA contractor on an earlier date. The excavation and piping areas were sampled for RRO, DRO, GRO, BTEX, PCBs, and HVO. The only detections were for RRO and DRO but below cleanup levels. The south edge of Tank 2 was located ~4' north of the north side of the current Maintenance Building (formerly the Old Transit Maintenance Facility) located at 3701 Dr. Martin Luther King Jr. Ave. (formerly 3650 C East Tudor Rd.). Part of the Tudor Road group of sites. Tank 1 that was formerly a part of this site is approximately 140' southwest of Tank 2. FKA L69.50.

6/12/2009 Site Visit Performed a site visit to verify the building exists, its footprint, and location to other buildings and contaminated sites in the area. Made a rough map of the buildings and noted the new addresses of buildings. Bill Petrik
7/31/2009 Document, Report, or Work plan Review - other This action is for Facility ID 1448, Tank 2 . Reviewed the Shannon & Wilson, Inc. “UST Closure Assessment, Municipality of Anchorage, Old Transit Maintenance Facility, 3650 C East Tudor Road, Anchorage, Alaska” dated July 1997, received 9/29/97. A 500-gallon waste oil UST (ADEC UST Facility ID 1448, Tank 2) installed in 1978, and associated piping were removed on June 25, 1997, cleaned, and taken to Alaska Metals Recycling for disposal and recycling. The UST was used to store waste oil from an oil/water separator housed inside the building that had been removed by a MOA contractor on an earlier date. The distance from the building to the nearest tank edge was ~4’. The top of the tank was 5’ bgs and the bottom at 9’ bgs. The total depth of the excavation was 10’. Approximately 26 c.y. of potentially contaminated soil was excavated and placed on a 10-mil reinforced liner. All laboratory samples were submitted for analysis of residual-range organics (RRO), diesel-range organics (DRO), gasoline-range organics (GRO), and benzene, toluene, ethylbenzene, and total xylenes (collectively known as BTEX). One sample each from the stockpile, UST excavation, and piping excavation were tested for polychlorinated biphenyls (PCBs), halogenated volatile organics (HVO), and total metals. Analytical test results indicate that soil remaining in the former UST excavation and the stockpile did not contain petroleum hydrocarbons above applicable ADEC cleanup levels. The maximum results for all samples for RRO and DRO in mg/kg were 210 and 180, respectively. All BTEX, HVO, and PCB results were ND. The maximum values for arsenic, cadmium, total chromium, and lead, in mg/kg, were 5.1, ND, 27, and 5.9, respectively, which are all considered within area background levels. These were from one sample each from the excavation, stockpile, and piping. Based on these sampling results the stockpile was used to backfill the excavation. No holes were observed in the UST upon removal. GW was not encountered in the excavation and is estimated to be between 15 and 20’ bgs. The nearest public well is located one mile southwest and the nearest private well is located ~1,750’ west. Bill Petrik
8/17/2009 Update or Other Action Created a new site for UST Facility ID 1448 Tank 1 only which was separated from this site that formerly contained both USTs Facility ID 1448 Tanks 1 & 2. Antoine Doiron
8/18/2009 Update or Other Action LUST site re-created in CSP database for source area 78454, 500 Gallon Waste UST Facility ID 1448-2 after the MOA - Maintenance Support Division Communications Shop and this site were split into unique sites. This new Source Area replaced former Source Area 78453. Bill Petrik
8/19/2009 Update or Other Action LUST site created in CSP database for source area 500 Gallon Waste UST 1448-2, 78454 Bill Petrik
8/20/2009 Update or Other Action File number changed from 2100.26.318 to 2100.26.564 as this site was separate from a file with two distinct sites. Susan Carberry
8/20/2009 Exposure Tracking Model Ranking A new updated ranking with ETM has been completed for source area 78454 500 Gallon Waste UST 1448-2. Bill Petrik
12/14/2009 Cleanup Complete Determination Issued A Record of Decision letter was sent this date granted a Corrective Action Complete Determination. No institutional controls will be associated with this closure. Analytical test results indicated that soil remaining in the former UST excavation and the stockpile did not contain petroleum hydrocarbons above applicable ADEC cleanup levels. The maximum results for all samples for RRO and DRO, in milligrams per kilogram (mg/kg), were 210 and 180, respectively. All BTEX, HVO, and PCB results were non-detectable (ND). The maximum values for arsenic, cadmium, total chromium, and lead, in mg/kg, were 5.1, ND, 27, and 5.9, respectively, which are all considered within area background levels. These results were from one sample each from the excavation, stockpile, and piping. Based on these sampling results the stockpile was used to backfill the excavation. Bill Petrik
