Ash Removal at Gateway Lake Site - Revised Report

Ellsworth AFB, South Dakota

Serial Letter ERS-3-RD-121

Dear Ms. Morrissey:

This letter is an updated version of the report we sent to you in Serial Letter ERS-3-RD-120. We

have revised the letter to respond to Corps comments received in your email dated March 21, 2007.

This letter report summarizes the ash removal work at the referenced site.

BACKGROUND

The Gateway Lake Ash Site (the Site) is located in the south-central portion of Ellsworth Air Force

Base (EAFB). Figures 1 and 2 show the site location within the base and a detailed site diagram,

respectively.

In 2001 - 2002, this area was under consideration by the Air Force for construction of a new building

for golf course maintenance activities and equipment. In August 2002, two soil borings were done as

part of the building planning and design. They found some buried ash and debris. Further

investigation determined that the area had been used for disposal of ash from the base incinerator

during the early years of operation of the installation. Additionally, the approximate boundaries of the

ash were delineated and the ash material was sampled and characterized. Details of the Site's

background are contained in the "Revised Work Plan for Excavation and Disposal ofAsh and Debris,

Gateway Lake Area" (the "Work Plan") dated October 2006.

The field investigation established that the ash material was not hazardous. The Air Force

determined that the ash material should be removed from the site and disposed properly at a

licensed land disposal facility (the Rapid City Landfill).

The Work Plan was prepared to manage the ash excavation, removal, and disposal project. The

Work Plan summarized the site history; described the approvals obtained from the Rapid City Landfill

and from the Environmental Protection Agency (EPA) for the disposal of the material at the

Rapid City Landfill; presented detailed plans for site preparation, excavation, removal, and site

restoration activities; and described confirmation sampling to document the removal of the ash

material.

Although the ash material was determined to be non-hazardous, EAFB is a Federal Superfund site.

Therefore, the Air Force obtained approval from Region 8 EPA for the off-site disposal of the ash

material. This permission is documented in Appendix A of this report.

Finally, a Health and Safety Plan was prepared to ensure that the removal work would be performed

in accordance with appropriate occupational safety and health measures.

REMOVAL ACTIVITY

Field work began at the site on January 2, 2007. A silt fence was installed and the contractor

mobilized equipment to the site. Topsoil that did not contain ash or debris was stripped and

stockpiled for later reuse.

The Work Plan called for the temporary removal of a chain link fence that crosses the site. However,

during the pre-construction meeting, the Air Force determined that the fence was a Base perimeter

fence that could not be temporarily removed. Therefore, the ash material north of the fence was

excavated, lifted across the fence, and loaded into trucks located south of the fence.

Excavation, loading, and disposal of ash began on January 3 and continued until January 26, with

interruptions for several days due to extreme weather conditions. The quantity of ash substantially

exceeded the estimate contained in the work plan. The excavated area was backfilled with material

obtained from two on-base sources, including stockpiles located west of the runway and material

excavated from a building construction project adjacent to the North Docks. These backfill material

sources were provided by the base and by the Corps of Engineers. No specific testing of the backfill

was performed; but the material appeared to be clean, with no evident odor or visual contamination.

A minor amount of the ash material was left in place, due to budgetary constraints and due to the

presence of the fence and a watermain. The area of ash removal, and the area where ash was left

in place, is shown on Figure 3 (attached).

Area 1 (Figure 3) is a buried layer of ash, with a thickness of 1 foot at the fence. The layer

decreases in thickness to the west and ends about 20 feet west of the fence.

Area 2 was left in place due to the presence of a watermain, a 90 degree bend in the watermain, and

the associated thrust block which could not readily be moved. The buried ash layer is about 4.5 feet

in thickness at the north-south fence. The layer decreases in thickness to the west and ends about

30 feet west of the fence. The watermain is shown on Figure 3.

Final backfilling and site grading were completed on January 29,2007.

Prior to the project, Earth Tech, Inc. (Earth Tech), submitted analytical data to the Rapid City Landfill

demonstrating that the material was non-hazardous. This information is summarized in the revised

work plan, dated October 2006. The Rapid City Landfill requested additional testing, which was

performed by Earth Tech and provided to the Landfill. On the basis of this data, the Landfill

determined that the ash material could be accepted at the Landfill and could be used for daily cover.

A total of 4,31 0 cubic yards of ash material was hauled to the Rapid City landfill. This compares to

an estimated quantity prior to the work of 3,000 cubic yards. The ash material was accepted by the

Landfill Facility at no charge, since it could be used there as daily landfill cover. The absence of

tipping fee costs enabled the Air Force to remove the extra 1,310 cubic yards within the original

project budget.

CONFIRMATION SAMPLING

The excavation and removal of the ash material continued until native soils were reached, as

determined by visual inspection. Six confirmation samples were collected in accordance with the

Revised Work Plan. Soil samples were collected after the ash was removed from the floor of the

excavation, and the samples were analyzed for semivolatile organic compounds (SVOCs). Locations

were selected to spatially represent the excavated area. Approximate sample locations are shown

on Figure 3.

Concentrations for detected compounds were compared to the EPA Region 3 Risk Based

Concentrations (RBCs), using the October 31, 2006, update. Since the ash removal area was

backfilled with clean soils, the industrial RBC for dermal and inhalation risk did not apply. Results

were compared to the dilution attenuation factor (OAF) of 20 for evaluating the soil to ground water

migration pathway.

Detected SVOCs were:

Sample 10

SS05

Analvte

bis(2-ethylhexyl)phthaIate

Units

ug/kg

Detected

Concentration

74

OAF

2,889,000

No other SVOCs were detected. Analytical results are attached in Appendix B.

For this updated letter report, we have included the RBCs table from April 2007 (see Appendix B).

The values in the April 2007 version are unchanged from the October 2006 version with respect to

bis(2-ethylhexyl)phthalate.

RESlORAlION

The excavated area was restored by backfilling with clean soil from stockpiles and excavations on

the base, as described above (page 2). The area was seeded in March, 2007.

RE: Ash Disposal at Ellsworth AFB, South Dakota

Hello Keith Thanks for your request. Sorry about the mix up.

Here's the VCA for the Rapid City Landfill.

The OSR acceptability status is dynamic in nature and subject to change, Region 8 has

instituted a policy where we conduct a verification of continued acceptability (VCA) on

facilities that have been previously found acceptable under the CERCLA Off-site Rule

(OSR). The purpose of a VCA is provide a periodic check to assure that the facility

continues to be acceptable. VCAs are conducted when a request for OSR status is received

and the previous VCA had been conducted more than 60 days prior. VCA are valid for 60-

days.

A VCA was completed for the Rapid City Landfill facility on January 2, 2007, so tre VCA is

valid until March 2, 2007. Again, VCA are valid for 60-days. CERCLA waste shipments sent

to the Rapid City Landfill facility up until March 2nd are in full compliance with the

OSR. If CERCLA wastes are planned to be sent after this date, please contact me about a

week or so prior to March 2nd, so that a new VCA can be conducted at that time. lhanks.

RE: Ash Disposal at Ellsworth

AFB, South Dakota

Terry - We are planning to begin work on the ash removal project for Ellsworth AFB next

week (the week of January 1). It probably will take several weeks and likely will extend

past the current VCA date of January 13.

1 4528 00009
Therefore. we request a renewed VCA to extend 60 days past January 13.

Barring exceptionally bad weather, this will be sufficient for us to complete the work.

Thanks for your assistance. Please contact me if there are questions.

Ash Disposal at Ellsworth AFB,

South Dakota

Terry - this pertains to the proposed excavation of incinerator ash at Ellsworth AFB,

South Dakota, transport of the ash to the Rapid City Landfill, and disposal of the ash

material at the Rapid City Landfill.

Background

Jerry Canfield contacted you May 3, 2006 (via email) about this project and inquired about

CERCLA Off-Site Rule requirements. You provided a response to him via email dated ~lay 4.

Since the project was delayed on our end, I sent another email to you on June 30, stating

that we hoped to perform the work in July or August but that it could be delayed until

September or October. The project has moved slowly, but we think we are prepared to

perform the work before the end of December.

Request

In accordance with your May 4 email, this email is our notification to EPA that we plan to

dispose of this non-hazardous ash material at the Rapid City Landfill. We request that EPA

conduct a new verification of continued acceptability (VeA) for the proposed project.

Please let me know if you have any questions.

Thanks in advance for your help.
