Ash Removal at Gateway Lake Site

Ellsworth AFB, South Dakota

Serial Letter ERS-3-RD-120

Dear Ms. Morrissey:

Minneapolis. MN 55441 www.earthtech.com

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.

The area was under consideration by the Air Force for construction of a new building. In August 2002

two exploratory borings were advanced. They detected 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. Further site investigation delineated the approximate

boundaries of the ash and characterized the ash material. Details of the Site's background are

contained in the "Revised Work Plan for Excavation and Disposal of Ash 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. 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 several on-base sources, including stockpiles located west of the runway and material

excavated from building construction projects adjacent to the North Docks.

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. 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.

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

A total of 4,310 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:

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

RESTORAliON

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

the base. The area will be seeded in spring 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; ~:,

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 facili ty

continues to be acceptable. VCAs are conducted when a request for OSR status is receic;~j

and the previous VCA had been conducted more than 60 days prior. VCA are valid for 6)-

days.

A VCA was completed for the Rapid City Landfill facility on January 2, 2007, so tte \'C~ i~

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

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

aSR. If CEReLA wastes are planned to be sent after this date, please contact me about

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

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

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

past the current VCA date of January 13.

Keith I have a call into the State for compliance/release status at the Rapid City

Landfill. I'll get back to you when I hear back from them. However, I will not be in tte

office on Thursday or Friday and will have to get back to you on Monday (11/20). If you

need an answer before next week, please call me (303-312-6419). Thanks.

Ash Disposal at Ellsworth AFB,

30'lth Dakota

excavation of incinerator ash at Ellsworth AFB,

the Rapid City Landfill, and disposal of the ash

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 May 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 Ive 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 pler! tG

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

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

Please let me know if you have any questions.

Thanks in advance for your help.
