2456.01 OOOO:RTE:neko1205 1. INTRODUCTION

1.1 Background

Approximately 30 years ago, Nekoosa Paper, Inc., now a wholly owned subsidiary of

II the Georgia-Pacific Corporation, acquired a parcel of land located adjacent to its Nekoosa Mill.

The site had previously been the location of a service station/auto dealer. In 1991, fill pipes

were discovered in this area. Upon further investigation, four underground storage tanks were

identified. Based on information from mill employees and local residents, it is believed that all

four tanks formerly contained gasoline and had been abandoned by filling with water. The mill

is located in theSE 1/4 of the NW 1/4, Section 10, T21N- RSE, Town of Nekoosa, Wood

County, Wisconsin (see Figure 1-1).

In November 1991, Georgia-Pacific retained RMT, Inc., to subcontract, observe, and

document the excavation, removal. and disposal of the four underground storage tanks at the I Nekoosa Mill.

1.2 Purpose and Scope

The purpose of this report is to document tank abandonment activities during the

excavation and removal of four underground storage tanks at the Georgia-Pacific, Nekoosa I . Mill. This report is based on the following:

• Site visit on November 11, 1991, to observe and document tank abandonment activities.

• Field-screening of soil samples for volatile organic compounds (VOCs) using a Hnu photoionization detector (PID).

• Laboratory analysis of soil samples from the excavation for total petroleum · hydrocarbons (TPH) as gasoline.

• Photographic documentation of tank abandonment activities.

• Documentation by subcontractors who also performed services related to the tank abandonment activities.

2. FINDINGS AND CONCLUSIONS

2.1 Findings

1. Four underground storage tanks ranging in size from 550 gallons to 3,000 gallons located at Georgia-Pacific's mill in Nekoosa, Wisconsin, were abandoned by RMT and its subcontractor, U.S. Petroleum Equipment of Combined Locks, Wisconsin, on November 11, 1991. The tanks had been used for the storage of gasoline over 30 years ago, when the property was formerly a service station. Table 2-1 provides the identification number and specific information for each tank.

2. The tanks were constructed of single-wall steel and had no protective coating. No holes were observed in the tanks, but a welded seam on the west end of tank 4 and on the top of tank 2 were split. A split was also observed along a 1-foot section of one of the four fill pipes. All of the tanks were severely rusted and pitted on the exterior walls. The ends of all the tanks appeared to be bulged.

3. Prior to initiating removal activities, the following observations were made: Tank 1 contained 1.5 inches of liquid; tank 2 contained approximately 20 gallons of soil and leaves that presumably had fallen in through the split in the top seam after soil covering the tank had been excavated; tank 3 contained 0.5 inch of dry sludge; and tank 4 contained 2.5 inches of scale.

4. A single excavation that encompassed all four tanks was dug. The native soils surrounding the tank excavation consisted of a medium sand.

5. Soil samples were collected from beneath each end of each tank at a depth of approximately 9.5 feet below ground surface. One soil sample was also collected beneath the fill ports and at one location beneath the fill pipes at a depth of 2.5 feet. None of the ten samples collected exhibited petroleum odors, although the samples collected beneath the fill ports and fill pipes appeared to be stained. No stained soils were observed in the tank excavation.

6. All ten soil samples were field-screened with a photoionization detector (PID) for VOCs. I None of the samples were observed to have concentrations of VOCs above background levels (1-3 instrument units).

7. The excavation was backfilled to grade with the excavated soils and clean granular fill I material (specifically, 3/4-inch road mix graveQ.

8. Laboratory analysis of the soil samples collected beneath the tanks, fill ports, and fill I pipe in native soils contained no detectable concentrations of TPH.

9. At a depth of 9.5 feet below ground surface, soils were moist; however, groundwater I was not encountered in the excavation. Based on previous unrelated work conducted In the vicinity, groundwater is approximately 10 feet below ground surface.

2456.01 OOOO:RTE:neko1205.t 2.2 Conclusions

1. Based on the results of field-screening and laboratory analysis, petroleum from the former underground storage tanks has not impacted soils·in the vicinity of the underground storage tanks and associated piping.

2. The bulging and split seams observed on the tanks and fill pipe are likely to have I been due to the freezing and expansion of water which was placed in these tanks when they were initially abandoned over 30 years ago.

I 2456.01 OOOO:RTE:neko1205 2-3

I 3. RECOMMENDATIONS

1. Based on observations made during tank abandonment activities and on the results of both field and laboratory analyses of soil samples collected from beneath the tanks, no further action at this site is recommended.

2. RMT recommends that this report be submitted to the Wisconsin Department of Natural Resources and to the Wisconsin Department of Industry, Labor and Human Relations (WDILHR), as required by current established regulations.

4. TANK ABANDONMENT ACTIVITIES

4.1 Tan!(_Description

The four underground storage tanks present at the site ranged in size from

550 gallons to 3,000 gallons, and were all removed from an area just north of the "old salvage

building• on the Georgia-Pacific property. Table 2-1 provides detailed information for each I tank. The tanks were excavated and removed from the site on November 11, 1991. Photographic documentation of the tanks is provided in Appendix A. I 4.2 Tank Cleaning, Excavation. and Removal

RMT, Inc., and its subcontractor, U.S. Petroleum Equipment, of Combined Locks, I Wisconsin, excavated and removed four underground storage tanks and the associated piping from an area immediately north of the •old salvage building• at the Nekoosa Mill (see I Figure 4-1). Prior to the arrival of RMT and its subcontractor, the soils over the tops of the four tanks had been removed by Georgia-Pacific, and the fill pipes had been cut off at the

south edge of the excavation. No vent pipes for the tanks were present. r Prior to excavation, the Lower Explosive Umit (LEL) for each tank was checked using

an explosimeter. All tanks showed an LEL of 0; therefore, inerting of the tanks was not I necessary. All of the tanks were also checked for contents, and were found to contain between 0 and 3 inches of residual sludges. The tanks were excavated and removed from the

ground using a rubber-tire backhoe. After the tanks were removed, openings were cut into

the tanks to allow for ventilation and access. Georgia-Pacific health and safety personnel were

on-site to check tank atmospheres and to complete the tank entry permit. Each tank was I rinsed using a pressure washer after all of the sludges had been removed. Tank sludges and cleaning liquids were placed in 55-gallon Department of Transportation drums, labeled, and I stored on-site. The drums were sampled by JAVCO, Inc., of De Pare, Wisconsin, and I characterized and disposed by Avganic Industries at their facility in Cottage Grove, Wisconsin. 2456.01 OOOO:ATE:neko1205 4-1 I I ·------

The drums were removed from the Georgia-Pacific site on January 6, 1992. A copy of the

waste characterization laboratory report form is provided in Appendix B; however, manifests

I for the four drums were unavailable at the time of publication of this report.

A burn permit was issued by Georgia-Pacific to allow the 3,000-gallon tanks to be

torch-cut on-site. All tanks except for the 550-gallon one were transported to U.S. Petroleum I Equipment in Kimberly, Wisconsin, where they were subsequently processed as scrap steel at Sandoff Metal Salvage, Fond du Lac, Wisconsin. The 550-gallon tank was transported by

JAVCO to their shop in DePere, Wisconsin. The tank was subsequently processed as scrap

steel at Lasch Wrecking, in Green Bay, Wisconsin. Appendix B contains disposal

documentation, and Appendix C provides a copy of the WDILHR Underground Petroleum

Product Tank Inventory form for each tank.

The soils overlying and surrounding the tanks consisted of a clean medium sand. The

excavation was backfilled with the previously excavated material and 3/4-inch road mix gravel

from a local source. The fill was compacted using the excavation equipment.

I Soil samples were collected 1 foot below each end of each tank at a depth of I approximately 9.5 feet below ground surface. Field soil vapor headspace analysis conducted with an Hnu PID showed no levels of VOCs greater than 3 instrument units in any of the I samples collected from the tank excavation. One soil sample was also collected from beneath the fill ports and from beneath the fill pipes approximately halfway between the fill ports and

I the tanks. Both of these samples consisted of sand and appeared to be stained. Field I headspace analysis revealed no detectable concentrations of VOCs at either location. All samples were submitted for laboratory chemical analysis at RMT Laboratories, Madison, I Wisconsin. I I I 2456.01 OOOO :RTE:neko1205 4-3 I I

~ 4.3 VIsual Tank Observations

After removal, the tanks were visually inspected by the RMT site representative. All

I tanks were constructed of single-wall steel with no protective coating. The tanks were

severely rusted and pitted on the outside; however, no holes were observed in the tank walls.

Welded seams on several of the tanks were cracked or split, including ttie following: I • The top seam on tank 2 which ran the length of the tank • The center seam on tank 3 which split during removal activities

• The end seam, near the bottom of the west end of tank 4

The split seams are likely to be the result of freezing and expansion of water that was used to

initially abandon the tanks. Ken Hartje, Assistant Fire Chief for the Town of Nekoosa, was on

I site to observe tank abandonment activities. A copy of the WDILHR Underground Petroleum

Product Tank Inventory form for each tank is contained in Appendix C.

4.4 Soli Sampling and Analysis for TPH

As indicated on Figure 4-1, soil samples were collected from beneath each end of

I each tank and beneath the fill ports and fill pipes (total of 1o soil samples) for laboratory

analysis of TPH as gasoline. The samples were analyzed using the "California Method. • The

analytical results are summarized in Table 4-1. Soil sample chain-of-custody forms are

provided in Appendix D, and laboratory reports are included in Appendix E. Field sampling

methods are described In Appendix F.

I Laboratory analysis of the samples collected from beneath the tanks, fill ports, and fill I pipes identified no concentrations of TPH above the analytical detection limit of 5.0 - 5.5 mg/kg. No staining of soils or petroleum odors was observed in the base or sidewalls of

the tank excavation. However, stained soils were observed in the immediate vicinity of the fill

ports and fill pipes. Staining was limited to shallow soils 1-2 feet below ground surface. I 2456.01 OOOO:RTE:neko1205 4-4

Notes:

Soil samples were collected by RMT personnel and analyzed at RMT Laboratories.

2 The photoionization detector (PID) provides indirect indicators of the level of VOCs which may be present in excavated soils. The PID primarily indicates the relative differences in' readings between samples. The PID had a 10.2-eV lamp and was calibrated to an isobutylene standard. Due to moisture interference, some samples were recapped and reanalyzed.

3 TPH - total petroleum hydrocarbons as gasoline. All TPH analyses were performed using the •california Method. •

2456.01 OOOO:RTE:neko1205.t I

Subsequent laboratory analysis of the stained soils (samples L 10 and L 11) did not contain I detectable concentrations of TPH. I 4.5 Discussion of ResuHs Based on field observations and chemical analysis of soils from the tank and piping

I. excavation, petroleum constituents do not appear to be present in the soil in the area of the

former underground storage tanks. Dark stained soils were observed in the area of the fill

I pipes, but neither field-screening with a PID nor laboratory analysis revealed detectable levels I of petroleum hydrocarbons. Staining observed in this area may be the result of an old release (i.e., more than 30 years ago) which, due to the loose, granular nature of the native soils and I the natural bio-degradation, has resulted In non-detectable concentrations of petroleum constituents.

I APPENDIX F I SAMPLING AND HNU FIELD-SCREENING METHODOLOGY

Soil Sampling

Soil samples were collected from the backhoe bucket from approximately 1 foot below

each end of each tank. The samples were analyzed for TPH as gasoline using the "California

Method. • Samples collected for TPH analysis were stored in appropriate bottles; labeled with

I the sample number, location, and date; and put on ice immediately after collection. Sample

bottles, labels, and forms had previously been supplied by RMT Laboratories. The samples

were transported to RMT Laboratories in Madison with appropriate chain-of-custody

documentation.

Field-Screening Soil Samples I Soil samples were screened for VOCs in the field using an Hnu Systems, Inc., Model IS PI 1 01 portable photoionization detector (PI D) equipped with an 10.2-eV lamp. The ambient

outside air temperature during sampling ranged from 24° to 30°F. Weather conditions were

cloudy, cold, and damp. After the samples were collected in B-ounce jars, they were covered

I with foil and allowed to equilibrate to a temperature of approximately 70° F in a heated vehicle

for about one-half hour. The air in the headspace of each jar was then sampled by inserting

I the probe of the PID through the foil. The meter readings for each sample were recorded in

the field notebook. The PID was calibrated using an isobutylene standard before use in the

field. It should be noted that the Hnu photoionization meter used for field-screening soil

samples provides a qualitative indication of the presence of potential petroleum soil

contamination, and is not intended to provide a quantitative measure of the level of

I contamination. Levels measured by other means of analysis could produce substantially

different results.
