I INTRODUCTION

On September 19, 2000, the Region 6 Superfund Technical Assessment and Response team(START) contractor, Ecology and Environment, Inc. (E & E), was tasked by the United StatesEnvironmental Protection Agency Response and Prevention Branch (EPA-RPB) to provideremoval assessment support under Contract 68-W6-0013, Technical Direction Document (TDD)S06-00-09-0011. Specific tasks included providing cost and volume estimates for thewaste/drum cascade area and the contaminated drainage areas at the site, west of Highway 142.The cost estimate is for encapsulating the waste on-site.

II BACKGROUND

The Imperial Refining Company (IRC) was a crude oil refining facility that operated from 1917until 1924. According to ODEQ's Preliminary Assessment report, the Sanborn Fire InsuranceMap of the refinery showed that the refinery's tanks and buildings were removed in 1924. Thelarge amount of waste present on the ground indicates that waste products associated with thestructures were dumped onto the ground during the dismantling of the refinery's structures,tanks, and piping. Wastes generated during dismantling operations included contaminated soilsfrom tank bottoms, coke piles, reservoir sediments, and rubble from buildings. IRC declaredbankruptcy in 1934.

The legal description of the property is the SE1/4 of the NE1/4 of Section 20, and the SW1/4 ofthe NW1/4 of Section 21, Township 4 South, Range 2 East, Carter County, Oklahoma. IRCowned additional land in the SW1/4 of the NW1/4 of Section 21, Township 4 South, Range 2East, to the south and east of the Atchison, Topeka, and Santa Fe railroad tracks, bringing thetotal amount of property owned by IRC to approximately 80 acres. According to county records,C.W. and Miriam Hogan presently own the land where IRC operated.

From December 8-10 and 16-17,1998, START members surveyed the site to develop wastevolume estimates. START members utilized Global Positioning System (GPS) technology andTotal Station Electronic Distance Measuring (EDM) instruments to survey the areas containingwaste piles. Approximately 10 to 30 measurements were taken along the perimeter of eachwaste pile to determine its surface area. START members used a Geoprobe™ hydraulic pushsampler and JMC slam-bar samplers to determine the depth of the tar and oily clay layers, anddistance to the clean clay layer (by visual observation) in each area. Approximately 10 to 40depth measurements were taken along transects in each area.

See START'S Removal Assessment Report for Imperial Refining Company, TDD S06-98-10-0020 for a detailed description of volume calculations and sampling missions.

Ill VOLUME AND COSTS ESTIMATES

The waste/drum cascade area was referred to as Area B and the contaminated drainage pathwayinto the wetlands west of Highway 142 was referred to as Area D in the Removal AssessmentReport for Imperial Refining Company. The volume estimates for the two areas are:

Waste/Drum Cascade Area 1,383 cubic yardsDrainage Pathway Area 1.854 cubic yards

Total 3,237 cubic yards

TDD No. S06-00-09-0011

CERCLIS No. OK0002024099

Cost estimates were calculated for encapsulating the wastes on-site. Estimates were determinedfor three possible options: each area separately, and both areas combined. The followingequipment is included in all cost estimates:• One dozer (D4 or D6) with disc attachment. Two dump trucks (16.5 cubic yards)• One sheepfoot roller/compactor• One 3,000-gallon water truck• One track-hoe hydraulic excavator (1.5 cubic yard)• One front-end loader (1 cubic yard)

For encapsulating the waste on-site, it was estimated that a half-acre area would have to becleared and graded. Table 1 lists the approximate sizes of the encapsulation cells for the threeoptions.

Table 1Encapsulation Cell Size

AreaWaste/Drum AreaDrainage AreaBoth Areas Combined

Length (ft)100100125

Width (ft)100100125

Height (ft)688

For all three encapsulation options, the following assumptions were made:. 1-foot clay base for encapsulation area,. 1.5-feet clay cap,. 0.5-foot topsoil cover over clay cap,

1:3 slope for sides of cell.

The R.S. Means, Environmental Cost and Handling Options and Solutions 1997 handbook wasused to estimate capital costs. The estimated capital costs (excluding labor, oversight, etc.) foreach option is:

Waste/Drum Area $58,000Drainage Area $63,000Both Areas Combined $92,000

For detailed descriptions of each option's cost estimate, see Tables 3, 4, and 5 in Attachment A.

Since contractor labor rates were unknown, the hours for each task were included in Table 2.The hours can be used to calculate labor costs once the number of personnel on-site and theirassociated labor rates are known. For cost estimation purposes, it was estimated that a four mancrew would operate equipment on-site.
