1.0 INTRODUCTION AND BACKGROUND

Citadel Environmental Services, Inc. (Citadel) is pleased to provide this Division 5 Permit Application on behalf of 4Granite Inc. (Contractor) and the Department of Veterans Affairs Greater Los Angeles Healthcare System(VA-GLAHS) (Owner).

An approximately 300,000-gallon Underground Storage Tank (UST) is proposed to be abandoned in place. Citadel understands that the UST may have been installed in or around 1964 and is constructed of reinforced concrete with an interior and exterior protective coating. The dimensions of the UST vault are 85 feet by 48 feet. The UST was used for bulk storage of fuel oil for an on-Site boiler house and was placed out of service in 1993. The fuel oil was removed at that time and the tank interior cleaned. Residual water remains in the UST and will be pumped out as part of the closure process. Please refer to Figure 1 for the site location and Figure 2 for the UST and transfer piping locations.

2.0 PREVIOUS INVESTIGATIONS

In August 2016, Citadel advanced seven soil borings surrounding the UST perimeter using a direct push drill rig. Borings identified as Soil Boring-1 (SB-1) to SB-5 and SB-7 were advanced to 25 feet bgs. Boring SB-6 attempted to reach groundwater but encountered refusal at 41.5 feet below ground surface (bgs).

Soil samples were analyzed for Total Petroleum Hydrocarbons (TPH) by EPA Method 8015B and Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) by EPA Method 8260B. Results were non-detect for BTEX compounds in each soil sample. TPH was non-detect in each soil sample, except the 15-foot bgs samples from borings SB-1 and SB-7, both located near the southern end of the UST. Maximum concentrations of TPH as gasoline (TPHg), TPH as diesel (TPHd) and TPH as oil (TPHo) were 5.72 mg/kg, 1,300 mg/kg and 27.5 mg/kg, respectively. A copy of this report is included in Appendix 1.

On June 5, 2018, Citadel advanced 12 soil borings (identified as SB-1 to SB-12) adjacent to the transfer piping between the UST and the boiler building located northeast of Bonsall Avenue, using a direct push drill rig. These borings were advanced to depths of between five and 15 feet bgs.

Based on the results of the geophysical survey and visible observations, the base of the underground conduit that runs between the UST and the boiler building northeast of Bonsall Avenue is located approximately five to six feet below grade adjacent to the UST; approximately 10 feet below grade after turning to the northeast across Bonsall Avenue; approximately 15 feet below grade perpendicular to Bonsall Avenue; and approximately 10 feet below grade near the boiler building. Based on these approximate depths, four soil borings near the UST (SB-1 to SB-4) were advanced to approximately six feet bgs; two borings across Bonsall Avenue (SB-5 and SB-6) were advanced to approximately 10 feet bgs; four borings along the conduit perpendicular to Bonsall Avenue (SB-7 to SB-10) were advanced to approximately 15 feet bgs; and two borings near the boiler building (SB-11 and SB-12) were advanced to approximately 10 feet bgs.

Field measurements using a photo-ionizing detector (PID) for the soil samples ranged from 0.0 to

0.1 parts per million (ppm). The soil samples were analyzed for TPH by EPA Method 8015B and BTEX compounds by EPA Method 8260B. TPH and BTEX compounds were not reported above laboratory practical quantitation limits (pql) in any of the soil samples.

On June 6, 2018, Citadel advanced two borings to groundwater (identified as GB-1 and GB-2) at the southwest and northeast sides of the UST using a hollow stem auger rig.

11301 WILSHIRE BOULEVARD

1237.1001.0_LAFD_Division_5_Permit_Application_MD 2

To determine approximate depth to groundwater at the Site, Citadel reviewed the Regional Water Control Board Geotracker database of known environmental cases in the Site vicinity. A former UST case located approximately 3,300 feet east of the Site encountered groundwater during a 2008 sampling event at an approximate elevation of 264 feet msl. A former UST case located approximately 3,800 feet west of the Site encountered groundwater at approximately 271 feet above msl during a 2009 sampling event. Each of the sites reviewed show the groundwater gradient in the area approximately to the south or southeast matching the topography in the area and placing the sites to the east and west directly cross gradient from the Site. Using the Site elevation of approximately 350 feet msl, and the groundwater elevation at the two cross gradient sites, groundwater was expected to be encountered between 264 and 271 feet above msl or approximately 79 to 86 feet bgs.

Citadel collected soil samples from the groundwater borings at five, 15, and 20 feet bgs; and at ten-foot intervals thereafter. Groundwater was encountered in the GB-1 and GB-2 at approximately 95 feet bgs.

VOCs were not detected during the field screening with the PID in any of the soil samples from GB-1 and GB-2, with the exception of the 60-foot sample from GB-1, at 0.1 ppm. The soil and groundwater samples from the groundwater borings were analyzed for TPH by EPA Method 8015B, BTEX compounds and methyl tert-butyl ether, di-isopropyl ether, ethyl tert-butyl ether, tert-amyl methyl ether and tertiary butyl alcohol (oxygenates) by EPA Method 8260B. TPH, BTEX compounds and oxygenates were not reported above the laboratory pql in any of the soil and groundwater samples.

A water sample was collected from the UST and was also analyzed for TPH by EPA Method 8015B, BTEX compounds and oxygenates by EPA Method 8260B. TPH, BTEX compounds and oxygenates were not reported above the laboratory pql in the UST water sample.

A copy of the report covering the June 5 and 6, 2018 activities is included in Appendix 2.

3.0 DIVISION 5 PERMIT APPLICATION NARRATIVE

The UST is proposed to be Abandoned-in-Place by filling the tank void with a cellular concrete mixture. The cellular concrete mixture has the strength characteristics of 2-sack slurry with the added benefits of being highly pumpable and a flowable mixture. For every truckload of bulk cement, the cellular concrete mixture will produce 120 cubic yards of fill material.

The process of filling the UST will involve setting up a portable batch plant onsite to mix the concrete with the cellular foam. Once the equipment is set up at the site, the established mix design will be reviewed by the pump operator for the pounds of cement per cubic yard, the gallons of water per cubic yard and the amount of foam per cubic yard. The slurry is pumped to the In-Line Blending System where the pre-formed foam is introduced into the slurry, producing the air-filled cellular concrete. The volumes placed in the tanks will be verified by comparing the theoretical volume with the amount of cement delivered and water used.

The cellular concrete mixture will be inspected and sampled using any of several standard sampling containers. This sample is weighed and compared to the density in the specific mix design. If adjustments are required, they will be made and the procedure is repeated. Once the sampled density conforms to the mix design density, the cellular concrete mixture will be placed inside the tank. Density samples are taken every fifteen (15) minutes for the first hour to ensure uniformity. Thereafter, the density samples are taken every half hour, again to ensure uniformity.

11301 WILSHIRE BOULEVARD

1237.1001.0_LAFD_Division_5_Permit_Application_MD 3

The material will be gravity fed from into several openings in the tank at the surface. Roughly 2.5 feet per day of cellular concrete material will be placed into the tank. Each day the depth of the cellular concrete backfill will be monitored to ensure the level of the grout is being brought up uniformly to ensure no voids remain during the first lifts. There is the potential to leave voids at the top of the tank during the final lift. To minimize this, the final lift will be pumped to move the material to the extremities of the tank and ensure most of the trapped air pockets are expelled.

At the end of each working day, reports of cellular concrete placement will be completed and the depth of cellular concrete will be monitored. Reports will be turned in each day prior to start of work the next day.

A two-inch pipe connects the UST to the Boiler Plant. The pipe is enclosed in an underground concrete tunnel and the pipe is capped at the Boiler Plant end. Based upon the soil borings and sampling analysis results, there is no evidence of piping leaks. During the UST closure actions, the pipe will be uncapped, emptied of any residual fluids, recapped, and left in place.

A structural engineer has reviewed the Site and available UST plans, and has determined that Abandonment-In-Place would be the least disruptive method of abandonment due to the size and location of the UST. A copy of the engineer’s letter is included in Appendix 3.
