SITE DESCRIPTION: Southeast Corner Oil Spill

SITE ID: NRF-65

WASTE AREA GROUP: 8

OPERABLE UNIT: 8-04

I. SUMMARY - PHYSICAL DESCRIPTION OF THE SITE:

NRF Unit 65 is the historical site of an oil spill which is located approximately 1200 feetsoutheast of the southeast corner of the Naval Reactors Facility (NRF) perimeter fence.The exact time of occurrence of the spill is unknown. It appears that light oil, such aslubricating oil, was dumped in this area. The affected area is approximately 30 feet by100 feet. The depth of contamination varies across the site from a few inches to morethan a foot.

Sampling was performed in the area and analyzed for benzene, toluene, ethylbenzene,and xylene (BTEX), total petroleum hydrocarbons (TPH), total metals, and a solventscreen. Results showed small amounts of benzene and toluene along with TPH up to8200 parts per million (ppm).

DECISION RECOMMENDATION

II. SUMMARY - QUALITATIVE ASSESSMENT OF RISK:

Low qualitative risk is highly certain at this site. This decision combination falls into the'no action required' area of the decision graph.

III. SUMMARY - CONSEQUENCES OF ERROR:

There is evidence that hazardous constituents are present at this site; however, thequantities are very small compared to the risk based concentration levels. If an incorrectdecision is made to perform no action, and the site actually contained significantquantities of undetected hazardous substances, they could possibly migrate from thearea, although migration is unlikely because the volume of the spill is limited, and basaltis present just below the soil surface. Wrongly making the decision to remediate thisarea would result in the unnecessary expenditure of resources that could be used forother higher priority sites at NRF.

IV. SUMMARY - OTHER DECISION DRIVERS:

No other decision drivers are present.

RECOMMENDED ACTION:

This site is recommended for no further action. Although there are hazardousconstituents present, they are in such small quantities that the risk associated with thesite would be very small.

Question 1. What are the waste generation process locations and dates of operationassociated with this site?

Bleck I Answer.

NRF Unit 65 is the historical site of an oil spill approximately 1200 feet southeast of thesoutheast corner of the Naval Reactors Facility (NRF) perimeter fence. The exact timethe spill occurred is unknown. It appears that light oil, such as lubricating oil, wasdumped in this area. The site is adjacent to a dirt road previously used as a connectionto the main road (Lincoln Boulevard) located east of the NRF.

The spill is located in an area where the topography differs from its surroundings. Itappears that the area was scraped level many years ago, possibly with the intent ofexcavating a gravel pit. The presence of basalt immediately below the soil surface wouldhave precluded this use. What appears to be a canal bank is located approximately 20feet east of the spill. This dike is elevated about six feet above the adjacent ground level,and has a longitudinal depression on top. This may have been one of the canals builtbefore the Idaho National Engineering Laboratory (INEL) was established.

Question 3. Is there evidence that a source exists at this site? If so, list the sourcesand describe the evidence.

Block 1 Ansa

There is evidence that a source exists at the site. Visual inspection of the area revealedsoil that is discolored (black). Sampling performed on the soil in June of 1994 indicatedthat a crust existed on the surface similar to asphalt. This crust varied in thicknessacross the spill area up to 1-1/2 inches. Discolored soil was encountered up to one footdeep and may have been deeper, but the extent of the excavation was only one footdeep. Four samples were taken from 3 different locations within Unit 65. TPH rangedfrom 190 ppm to 8200 ppm. Detectable levels of benzene were noted in two samplestaken from the same location. The samples showed 4.8 parts per billion (ppb) and 4.9ppb benzene. Toluene was also detected in one sample at the same location thatbenzene was detected. The toluene measured 2.0 ppb. Ethylbenzene and xylene werenot detected. A solvent screen did not detect any semi-volatiles. Total metal analysisshowed maximum results of: 216 ppm barium, 29 ppm chromium, 12.6 ppm lead, and7.6 ppm arsenic. No other metals were detected. All total metal results are below theupper tolerance limit and 90th percentile for the Test Area North (TAN) according to the"Track 2 Sites: Guidance for Assessing Low Probability Hazard Sites at the INE12. TANis the closes facility to NRF for comparison purposes.

Question 4. Is there empirical, circumstantial, or other evidence of migration? If so,what is it?

Block 1 Answer

There is evidence that some migration has occurred. This is evident from the darkcolored soil that was encountered approximately one foot deep. The extent of migrationis not known, however as noted in the field log book, basalt outcrop was present on thesurface in the unit. This would tend to limit migration to the layer of soil above thebasalt.

Question 5. Does site operating or disposal historical information allow estimation ofthe pattern of potential contamination? If the pattern is expected to be ascattering of hot spots, what is the expected minimum size of a significanthot spot?

Block 1 Answer.

Site operating or disposal historical information was not found for this site. Therefore, anestimation of the pattern of contamination based on this information could not be made,however because of the uniformity of the appearance of the spill site, it suggests that theoil was dumped on one occasion only. The heaviest saturation appears to be in thecenter of the spill area.

Question 6. Estimate the length, width, and depth of the contaminated region. What isthe known or estimated volume of the source? If this is an estimatedvolume, explain carefully how the estimate was derived.

Block t Ari,wo/

There is no source or evidence of migration in this area. The area of soil contaminatedwith petroleum hydrocarbons is approximately 30 feet by 100 feet, and conservativelyestimated at one foot deep across the whole site. An upper bound estimate of thevolume of oil necessary to cause the volume of contaminated soil which is present canbe determined by the equation below.

Migration of Water and Bulk Hydrocarbons in Soil 41

soil under isothermal conditions, the radius R of a mass of bulk hydrocar-bon can be grossly estimated":

R = (Q/3.142h), (2.9)where

Q = rate of hydrocarbon additiont = time after initial hydrocarbon addition to soilh = height of the oil film

Migration and Distribution of Light Bulk Hydrocarbon. Light bulk hydro-carbon will migrate downward in unsaturated zone soil due to gravity andcapillary forces. If the volume of released hydrocarbon is large, such as thoserelated to catastrophic spills, maximum lateral spreading and downward flowoccurs with all soil pores being saturated with hydrocarbon6°. Figure 2.12illustrates the hydrocarbon distribution most often displayed in the publishedliterature. The distribution illustrated in Figure 2.12 is valid for major gaso-line spills or tanker ruptures, but not for slow leaks; this case will be dis-cussed later in this chapter. The downward migration of light bulkhydrocarbon will eventually cease because (a) the mobile light bulk hydrocar-bon will be transformed into residual saturation, or (b) it will encounter animpermeable bed, or (c) it will reach the capillary fringe. Each situation isdescribed in greater detail below.As a mass of bulk hydrocarbon migrates beyond a unit mass of unsaturated

zone soil, a small amount of the total hydrocarbon mass will remain attachedto these soil particles via capillary forces. The bulk hydrocarbon that isretained by soil particles is known as immobile or "residual saturation." Themaximum amount of bulk hydrocarbon that can be retained by a soil is knownas residual saturation capacity. Residual saturation can potentially reside insoil in this state for years. If the migrating mass of bulk hydrocarbon is smallrelative to the soil surface area, the mass of bulk hydrocarbon will be even-tually exhausted as it is converted into residual saturation. When conversionis complete, downward migration ceases.The volume of soil required to immobilize a mass of bulk hydrocarbon

depends upon the porosity of the soil and the physical properties of the bulkhydrocarbon. The number of ycl, of soil required to immobilize a volume(barrels) of bulk hydrocarbon, VHC, can be grossly estimateclm:

V, = 0.2 Viic./P (RS) (2.10)where

VHC = volume of discharged hydrocarbon, in barrels(44 gal = 1 barrel)

V, = yd1 of soil required to attain residual saturation

P = soil porosityRS = residual saturation capacity

In general, the residual saturation capacity of soils is about 33 percent of

their water-holding capacity". The maximum residual saturation for light

oil and gasoline is 0.1; for diesel and light fuel oil, 0.15; for lube and heavy

fuel oil, 0.20. The maximum possible depth of penetration, D, in yards, can

be grossly estimated using the equation630:

D = V, / A (2.11)

where A is the area of infiltration. There is an alternative equation which

grossly estimates the maximum depth of penetration of a volume of bulk

hydrocarbon released on a soil":

D = KV,,c / A (2.12)

where K is a constant dependent upon the soil's retentive capacity for oil

and upon oil viscosity (see Table 2.3).Another non-rigorous formula for grossly estimating the maximum depth

of penetration of a volume of bulk hydrocarbon into the unsaturated zone

D = 1000 Vi4C / ARC (2.13)

whereR = soil retention capacityC = approximate correction factor based on the bulk

_ hydrocarbon viscosity (0.5 for gasoline to 2.0 for lightfuel oil).

Recommended values of R in liters per cubic meter are: 5 for stone to coarse

gravel, 8 for gravel to coarse sand, 15 for coarse to medium sand, 25 for

medium to fine sand, and 40 for fine sand to silt. If the soil has an inter-

mediate texture relative to those listed above, an intermediate value of

R should be used. Also, these values for R are for soils with an average

moisture content. For dry soils, R will be greater than the values listed above.

If a mass of bulk hydrocarbon which is migrating downward encounters

an empermeable layer, it will spread laterally until (a) the bulk hydrocarbon

is transformed into residual saturation, or (b) it migrates past the lateral extent

of the impermeable layer. If the latter situation occurs, vertical migration

will commence at the point where the lateral extent of the impermeable layer

has ceased. Downward migration will continue until (a) the bulk hydrocarbon

is transformed into residual saturation, (b) another impermeable barrier is

encountered, or (c) the bulk hydrocarbon encounters the capillary fringe.

From : Environmental Remediation

Date : January 8, 1993Subject : Interview of K. N. Drewes on Waste Disposal Sites

To : File

On the morning of January 6, 1993, I called K N. Drewes of the Idaho Branch Office

(IBO) in an attempt to obtain information about oil spill areas. Mr. Drewes visried the

Environmental Remediation office area in the S1W balcony about 1100 hours and

provided the following information while viewing Drawing 908E424, NRF Disposal Sites.

31 - A1W Oily Waste Soill

This is an area northwest of the A1W building where many portable compressors, both

diesel and electric, have been placed in support ot the plant air system. These

compressors have leaked both lube oil and fuel oil in this area.

59 - Original S1W Refuse Pit

Various types of waste oil were deposited in this area, including sludge from storaga

tanks in the S1W boiler house.

66 - Hot Storage Pit

Just south and east of the center line of the area matted on the drawing, an area was

excavated through asphalt and a gravel overlay. A black tarry substance oozed out of

the sides of the excavation, and expanded somewhat This area was at about the 18'

level. Recommend a three foot core sample in this area. (Could this be another part of

the oil/water separator overfiow?)

Between 1970 and 1974, there was a 13,000 gallon tank behind S1W which was used to

store chromated water.

58 - S1W Old Fuel Tank Soill

Two above ground fuel tanks were located north of the flammable storage shed east of

#1 Spray Pond. The actual truck unloading area was by the S1W pumphouse. A steam

plate on the ground between these two points identifies the underground trench which

carries service lines into the SW/ building. On one occasion, enough light fuel oll was

spilled to fill the service line trench, whith had to be bailed out with buckets.

65 - Southeast Corner Oil SDill

This is located on the side of an arroyo southeast of the perimeter fence off the

telephone line access road. It appears that approximately two barrels of oil similar to

File • 2 • NRFEM-RR•679

turbine lube oil (2190) were dumped here. Possibly oil which was contaminated withbilge water, or did not meet quality standards.

60 - Old Incinerator

The old incinerator was moved at the time of the perimeter fence upgrade because it didnot meet the 50 foot clearance requirement.

Corner of Batfish and Antietam

A newer curb is visible at this location. A fire main leak caused a sinkhole to form. Thearea was contaminated with Cesium, so the fire main was rerouted to the south at thispoint, and tied into the line just east of 624. The original line (86 - 101 was abandonedin place.

Area East of S1W Pumohouse (—NRF-151

The retention basins were overflowed to the storm drain by Geisler.

44 - S1W Waste Water Soill Area

Drains ran from S1W to NRF-44 and north along the east side of the Radiographybuilding and along the north side of the Radiography building and also drained to thearea south of NRF - 1, Field Area North of S1W.

South End of Building 624

Cesium has been found in this area, which was previously the Main Coolant PumpRefurbishment area. (I have heard that this area was contarninated from the PlantServices shower drain which was also located in this area.)

22 - A1W Paint Locker French Drain

This area was originally the A1W Chlorinator Shed. Mr. Drewes discovered two sailorspouring paint and solvent down the pipe stub in this area during the A1W Overhaul.

56 • Degreasing Facility

The building (627) was originally located on Gilbert Island Ave., which was west of theoriginal ECF building, and was used for railcar maintenance. It was moved to its currentlocation when the CESA was built. Three bays in the building, still visible as depressionsin the floor, were used to degrease A1W components packed in Cosmoline. Threedrains penetrated the north side of the building. A fractured conaete slab now coversthe area north of 627. Recommend sampling the drains and under the fractured slab.

File - 3 • NRFEM-RR-679

39 • Old Radicgraohy Area

The only artifact which remained in this area was the concrete backstop for the target.This was pulled into the ditch and the area backfilled during the perimeter fenceupgrade.

2 - S5G Surge Pond

This area was used for contaminated water and steam generator water disposal fromS5G, and includes the concrete 'steaming box' from S5G, which was dumped in thisarea in 1985-6.

13 - St VV Seepage Basin #3

This area can be located by the discontinuity in the inner perimeter fence.
