Project No: 1515


Ms. Mary Logan August 31, 2005 Remedial Project Manager (1515) USEPA 77 West Jackson Boulevard Chicago, IL 60604-3590

RE; Stevens Point Former Manufactured Gas Plant (MGP), Stevens Point, Wisconsin

Dear Ms. Logan:

On behalf of Wisconsin Public Service Corporation (WPSC), please find enclosed an initial data summary package for the upland portion of the former Stevens Point MGP site located in Stevens Point, Wisconsin.

Included are general information, a brief narrative summarizing work performed to date, site status, and a chronology of the record file. The data summary includes figures presenting the locations of soil samples, groundwater monitoring wells, geological cross sections, extent of soil remediation and documentation sample locations. Tables are provided to summanze analytical data collected at the site, which have been previously submitted to the Wisconsin Department of Natural Resources (WDNR) in reports on file.

Prior to transferring the site from WDNR to USEPA as lead regulatory agency, WPSC and NRT were in the process of evaluating groundwater concentrations and trends to determine if natural attenuation was occurring and supported site closure. The next annual groundwater monitoring event is scheduled for October 2005.

Please call Shirley Scharff at WPSC (920) 433.1396 or the undersigned if you have questions regarding the initial data summary package or if you require additional information.

Sincerely,

NATURAL RESOURCE TECHNOLOGY, INC.

STEVENS POINT MGP SITE

Wisconsin Public Service Corporation

General Information

Site Size: 3 acres Years of Operation: 1890s-1940s

Ownership: WPSC Gas Process: Coal Carbonization, Carbureted Water Gas (For Sale)

Major Site Features: The site is a vacant grass-covered lot bordering residential, commercial and city park land uses, approximately 200 feet east of the Wisconsin River

Site Status Summary

Overview of Remediation Work Completed

u Upland remediation work was completed by WPSC in 1998, including source

area excavation and thermal treatment (16,400 tons), and placement of cover soils for direct contact protection.

• Supplemental site mvestigations and groundwater monitoring is in progress to assess the feasibility of natural attenuation for residual groundwater quality impacts.

• An annual groundwater monitoring report including a proposed closure plan was completed in 2004. Additional wells were subsequently installed to define plume extent as agreed through discussions with the WDNR

• A sediment quality assessment was completed in 2000 including a small pond (0.2 acres) located in Pfiffner Pioneer Park and the adjacent Wisconsin River. A supplemental diver survey of Wisconsin River sediments was completed in 2002.

Status of Site Conditions & Monitoring

m Groundwater depth ranges from 2 feet in Pioneer Park to 10 feet below ground surface on the south site of the site. Flow is generally to the west away from the Wisconsin River due to the site being upstream of the Main Street Dam.

• Fill is present to a depth of 1 to 15 feet overlying high permeability sand and gravel. The fill is silty sand and gravel mixed with building debns, ash, cinders, slag, sawdust and wood fragments. Fractured granite bedrock occurs at 21 to 33 feet below ground surface (bgs) at the site (bedrock was encountered at 13.5 feet bgs during drilling of PZ-13B approximately 400 feet south of the site).

Post-remediation residual concentrations of PVOCs, PAHs and cyanide are present in soil and groundwater at the site, as described in the project reports of record.

Shallow groundwater quality has improved substantially following the source removal actions completed in 1998.

Deeper groundwater quality is being monitored by a network of eight piezometers and trends are stable or decreasing. Recently installed well nest OW-12/PZ-12B located off-site to the southeast had benzene and naphthalene concentrations above standards in the deeper well. PZ-13, located to the south, had no detections.

Water depths in the pond were 2 to 3 feet, with a soft sediment thickness of 2 feet. Water depths in the Wisconsin River vary from about 3 to 21 feet within the areas investigated, with soft sediment thicknesses of 0 to 2 feet based on poling information. The river bottom contained woody debris in many locations with sandy sediments within the interstices.

Based on sediment surface and core sampling performed in 2000, total PAH concentrations in the pond (Pioneer Park) were 10 to 260 mg/kg. In the Wisconsin River, concentrations were variable; highest concentrations were 11,000 to 20,000 mg/kg within the upper profile of the sediment in a localized area near the outlet to the former slough (samples T-203A and T-203B). Although tar, odors and sheen were noted on samples from the cores, this area of the river bed was covered by rock, boulders and debris and made core sampling difficult.

The subsequent diver survey m 2002 identified no visible tar in surface sediments in the vicinity of T-203A and T-203B.

Interim/Supplemental Actions Identified

Continued groundwater monitoring to demonstrate plume definition and stability (in progress).

Continued evaluation of groundwater discharges to the adjacent perforated storm sewer with respect to receiving stream surface water quality criteria (NR 105).

1) Concentrations that attain/exceed an NR 140 Preventive Action Limit (PAL) are shown underlined/italicized

2) Concentrations that attain/exceed an NR 140 Entorcement Standard (ES) are shown bold/underlined.

<1.9 : Parameter not detected above the limit of detection indicated

* : Laboratory note - Duplicate analyses not within control limits

& : Laboratory note - Laboratory Control Spike recovery not within control limits

B ; Laboratory note - Analyte present in the method blank

D : Laboratory note - Analyte value from diluted analysis, or surrogate result not applicable due to sample dilution. The may put the LOD above the NR 140 Standards

E : Laboratory note - Analyte concentration exceed calibration range

Q : Laboratory note - The analyte was detected between the limit of detection (LOD) and limit ol quantitation (LOO) Results qualified due to the uncertainty of values in this range

2 [C] = Carcinogenic, classified as B2, probable human carcinogen

3 - = parameter not analyzed

4 nd = parameter not detected above laboratory detection limit

5 RCL = WDNR generic Residual Contaminanl Level

6 PRG = US EPA Region 9 Preliminary Remediation Goals for direct contact

7 PRGs assume all dissociable cyanide as free cyanide

8 Sample depths measured with respect to pre-remedial ground surface elevations

9 Shaded sample results denote sample area was excavated and treated

Notes: A = Sediment lype based on sample collected by hydraulic push core

B = Poling bottom type based on poling results - the presence of large rocks was idenlified in some areas

based on the poling response Similarly, the presence of sand or soft muck could also be discerned during poling

"Sof l " indicates pole pushed until resistance was loo great due to hard bottom or friction

"Sandy or Gravelly" indicates pole encountered material that pole penetrated up to a few inches, but metallic pole

reverberation and sound indicated a generally large gram si7.e

"Rocky" indicates large rocks Pole bounced off the obstruclions. reverberation and sound indicated large, hard obstacle

Numerous attempts provided observations on obstacle (rock) size and general shape (flat or rounded rock)
