River OU-Technical Letter Report - Campmarina Former MGP Revision 0 3/22/2007

Section 1 - Introduction Page 1 of 30

1 INTRODUCTION

The fonner Campmarina Manufactured Gas Plant (MGP) Site (Site), located in Sheboygan, Wisconsin

(Figure 1), is divided into two operable units (OUs) - the Upland OU and the River OU. Pursuant to the

Administrative Settlement Agreement and Order on Consent (Settlement Agreement) dated January 26,

2007, a Technical Letter Report is to be prepared for each OU to summarize environmental investigation

and remediation activities undertaken at the Site. Natural Resource Technology, Inc. (NRT), on behalf of

WPSC, prepared this Technical Letter Report to address the River OU. The Upland OU is addressed in a

separate Technical Letter Report.

In the early 1990s, the City of Sheboygan (City) installed a dock along the Sheboygan River as part of its

Campmarina Park project. The excavation of footings for the dock uncovered coal tar contamination

associated with the form MGP operations, hi order to address the contamination, on March 24, 1992,

WPSC and the City entered into an environmental investigation/remedial agreement (Contract Number

SF-91-04) in accordance with Section 144.442, Wis. Stats. The Contract required a Remedial

Investigation/Feasibility Study (Rl/FS) be completed consistent with the requirements of the

Comprehensive Environmental Response Compensation, and Liability Act (CERCLA), 42. U.S.C.

§§ 9601 et seq., as amended, and the National Contingency Plan (NCP). WPSC completed an RI/FS for

the upland portion of the Site, which lead to the Wisconsin Upland Record of Decision on January 11,

2001 (2001 ROD). The remedy in the 2001 ROD was constructed in 2001 and is in the operation,

monitoring, and maintenance phase. (The ongoing work is more fully described in the Upland Technical

Letter Report.)

The Campmarina Site is physically related to the larger Sheboygan River and Harbor Site. However, the

Campmarina work is related to releases from the historic MGP operations (which ceased in the 1920s),

while the Sheboygan River and Harbor Site addresses PCB contamination associated with former diecast

operations that occurred up until the early 1970s.

The River OU Technical Letter Report summarizes the previous work undertaken to investigate the River

sediments near the Campmarina Site and discusses the current conditions of the River in the vicinity of

the fonner Campmarina MGP site. In general, the purpose of this Report is to:


RESOURCE

TECHNOLOGY



Briefly describe areas and/or media previously addressed with the Upland OU response actions completed under the State Issued ROD;

Summarize the results and status of the Sheboygan River and Harbor Superfund Site, as it relates to WPSC's Campmarina MGP Site;

Summarize the results of WPSC's preliminary investigations of the River OU;

Summarize remedial actions performed within the River OU;

Identify areas/media within the River OU that may warrant remedial measures and/or response actions; and

• Describe the additional work that will be incorporated into the Site-sp)ecific RI/FS Planning documents.

Property Location: NWl/4 of the SW 1/4T15N, R23E, Section 23 732 North Water Street Sheboygan, Wisconsin Sheboygan County

USEPA ID: WIN000510058

WDNR BRRTS #: 02060000095

The Upland OU encompasses an area of approximately 2.3 acres and is bounded by a private boat club

facility on the north, former North Water Street on the east, a vacant lot on the south, and the Sheboygan

River on the west (Appendix A, Sheet 1).

Based on preliminary findings of MGP residuals within sediments, the River OU is approximately 3.4 acres,

adjacent to the Upland OU. This area extends about 80 feet upstream of the former Campmarina northern

property line, as much as 120 feet outward from the shoreline, and about 900 feet downstream of the

fonner Campmarina southern property line, a short distance south of the Pennsylvania Avenue bridge

(Appendix A, Sheet 3).

1.2 Site History

Two methods of coal gas production were used at the Campmarina MGP. The coal gas production

method, used from 1872 to 1886, involved heating the coal in an airtight chamber (retort) which produced

coke and gases containing a variety of volatilized organic constituents. The process also produced tar

which was sold for roofing, wood treatment, and paving roads. The gas was passed through purifiers to

remove impurities such as sulfur, carbon dioxide, cyanide, and ammonia. Dry purifiers contained lime or

hydrated iron oxide mixed with wood chips. The gas was then stored in large holders on the property

prior to distribution for lighting and heating.

The carburetted water gas process, used from 1886 to 1929, involved passing air and steam over the

incandescent coal in a brick-filled vessel to form a combustible gas which was then enriched by injecting

a fme mist of oil over the bricks. The gas was then purified and stored in holders prior to distribution.

The Campmarina MGP operations ceased in 1929. Former aboveground MGP related structures (Figure

2 and Appendix A, Sheet 2) included the following:

1665 river ou tech Itr rev 0 final NATURAL RESOURCE

TECHNOLOGY

River OU-Technical Letter Report - Campmarina Fonner MGP Revision 0 3/22/2007


Three gas holders ranging in diameter from approximately 35 feet to 70 feet, the larger two with capacities of 70,000 cubic feet and 200,000 cubic feet;

One gas oil tank approximately 15 feet in diameter;

Three tar tanks; two approximately 30 feet by 8 feet and one approximately 20 feet by 5 feet;

One purifier approximately 25 feet in diameter; and

Gas manufacturing buildings including a garage, a gas meter shop, and a boiler room.

Based on review of Sanbom maps, the gas holders were removed between 1950 and 1955. Review of the

1955 Sanbom map indicates that many of the MGP buildings were still present in the Upland OU.

Sometime between 1955 and 1966, the remaining facility structures were razed and removed.

Numerous companies, which eventually became part of the Sheboygan Gas Light Company (SGLC),

owned the fonner Sheboygan MGP. In 1922, SGLC merged with other utilities to form WPSC. In 1966,

WPSC sold the prof)erty to Heileman Brewing Company (Heileman) for use as a parking lot. Heileman

sold the property in 1977, and it was then under ownership of three other non-manufacturing companies

until the City of Sheboygan purchased the property in 1985 when it became known as Campmarina.

Campmarina was equippied with gravel parking areas, electrical power and potable water for recreational

vehicle (RV) use. A docking area was also provided for recreational boat use on the Sheboygan River. In

2001 after WPSC completed upland remediation work, the City redeveloped Campmarina, North Water

Street adjacent to the property, and the property to the south (Center Avenue right-of-way) into a

neighborhood park called Worker's Water Street Park (Appendix A, Sheet 1).

Sanbom maps show the shorelines for the Sheboygan River at the former MGP property. Between 1891

and 1903, the channel appears to have been straightened by fill that extended approximately 60 feet into

the river. Subsequent Sanbom maps show that the shoreline did not change substantially from its present

location indicated on Figure 2.

During the Upland OU remediation (summarized in Section 1.4.1), a sheet pile banier wall was installed

along the Sheboygan River shoreline and the river bank was excavated and restored with filter gravel,

structural fill, and riprap. Details of the remedial action are provided in the Documentation Report (2(X)3,

NRT) and summarized in Section 4.


TECHNOLOGY



Based on review of the Sanbom maps. Boat Island is a man-made land mass located approximately 150

feet from the Site shoreline. The island is approximately 375 feet long by 105 feet wide (at its widest

point) and has several buildings which are used to store materials and supplies for the adjacent marina, the

Outboard Motor Club, located to the north of the Upland OU. The City of Sheboygan owns Boat Island .

The island has seasonal docking for boats.

Historical development activities adjacent (upstream) to the Upland OU included a property formerly

used as a tannery and a toy factory. Tannery operations terminated sometime between 1903 and 1940 and

the property was sold to Garton Toy Company (Garton). The 1950 Sanbom map indicates Garton used a

portion of the property adjacent to the river, directly across New York Avenue, for paint and lacquer

spraying.

1.3 Current Site Conditions

The Upland OU is now within Worker's Water Street Park with landscaped lawn, recreational areas,

seating, and sidewalks. The Park generally extends from the river on the west to 10* Street/North Water

Street on the east, and from the extension of Center Avenue on the south to Wisconsin Avenue on the

north. The Park footprint includes the former MGP property and abandoned right-of-ways for North

Water Street, Center Street, and New York Avenue.

An asphalt parking lot is located on the north side of the Park, with access from Wisconsin Avenue. A

small building constructed adjacent to this parking lot is shared by the Outboard Motor Club and WPSC. '

WPSC's use is related to the remediation work in the Upland OU, while the Outboard Motor Club uses it

to store equipment. The adjacent parking lot provides access to shoreline boat docks as well as additional

docks on Boat Island. North of the Park adjacent to the river is the former tannery and toy factory

building, which has been rehabilitated into multi-tenant housing.

South of the Park is a nanow parcel with a condominium unit at the northwest comer of Water Street and

Pennsylania Avenue. The Pennsylvania Avenue Bridge crosses the river just downstream of the Park and

former MGP. North Commerce Street parallels the river on its west side, with industrial/commercial

buildings located between the street and river.

Based on the United States Geologic Survey (USGS) Sheboygan North Quadrangle, photo revised 1973,

relief within one mile of the Site is approximately 95 feet, ranging from approximately 580 feet mean sea

level (msl) at Lake Michigan to approximately 675 feet msl northwest of the Site in the City of

Sheboygan. The ground surface elevation for the majority of existing Site groundwater monitoring wells

ranges between 588 and 591 feet msl; the Site slopes from Water Street to the Sheboygan River. The

elevation of the Sheboygan River ranges from about 578 feet msl (September 2(X)6) to 579 feet (August

2004), def)endent on the general elevation of Lake Michigan.

1.4 Overview of Previously Performed Activities

A summary of cunent Site conditions was provided to the United States Environmental Protection

Agency (USEPA) in October 2005. The Site status summary included information pertaining to the

upland remediation work performed and the status of Site conditions and monitoring, as well as a listing

of documents pertaining to the Site. A summary of the information included in the report is presented

below.

1.4.1 Overview of Remediation Work Performed

• Upland OU remediation work included soil excavation and thermal treatment (10,500 tons), installation of a containment system (sheet pile barrier around the perimeter of the Site and an engineered geosynthetic cover over the surface) and a biosparge system within the containment area (Appendix A, Sheet 1).

• Mass removal through soil excavation and thennal treatment followed by installation of the containment system is the primary remedy for the Upland OU. The biosparge system is currently in operation and is a secondary remedial measure. The biosparge system is undergoing performance monitoring to evaluate the effectiveness of longer term operation.

H Groundwater monitoring is conducted to demonstrate containment system performance. An Annual Operation, Maintenance, and Monitoring Report was submitted to USEPA and WDNR on November 28, 2005. The 2006 Annual Operation, Maintenance, and Monitoring Report will be incorporated into the Upland OU Technical Letter Report.

• Initial river sediment quality assessments were performed in 1995 and 1996.


TECHNOLOGY



1.4.2 Status of Site Conditions & Monitoring

• Groundwater depth ranges from approximately 5 lo 8 feet below ground surface. Flow is to the south-southeast toward Sheboygan River.

• Soils beneath the former MGP area include sand and gravel fill, and general fill with cinders over the entire former MGP to about 4 to 14 feet below ground surface, underlain by silty/clayey sand and clays to bedrock, at an estimated depth of 35 to 40 feet below ground surface. Thermally treated soils were replaced in the remedial excavations.

• Post-remediation residual concentrations of petroleum volatile organic compounds (PVOCs), polynuclear aromatic hydrocarbons (PAHs), and cyanide are present in soil and/or groundwater in the Upland OU. (ô i^c «-r\ â>J-ic>\s To^t, 7

u Shallow groundwater quality is close to or below Wisconsin Administrative Code, -Vupitcl Chapter NR140 standards at perimeter wells MW-705, 708 and 709R (outside of the ^ o P containment system. Appendix A, Sheet 1). Groundwater quality in deeper piezometers ^^•r«4vck'^'' (screened in clay at depth) exceeds standards at one location, PZ-703, and only for benzene.

• Groundwater elevation data demonstrates the containment of MGP-impacted groundwater. (Compare the groundwater elevations in MW-708 located outside the containment barrier with the groundwater elevations in MW-706 located within the containment banier.) ( CA-c.(v3 wâp V\ou37 ^

• The secondary measure of containment performance -contaminant concentration trends in monitoring wells - confirms containment. See monitoring wells MW-705, MW-708 and MW-709 and piezometers PZ-701, PZ-702 and PZ-703. The only exception is \ PZ-703 which indicates fluctuating groundwater concentrations. ( v-t^c«^^cd +« w* "-

• Biosparge system performance was measured based on contaminant concentration and geochemistry trends at shallow groundwater monitoring wells MW-701R, MW-706 and ^ i do MW-707R within the containment system. The trends indicate fluctuating to decreasing ( % y*f"'^J^'>'j, benzene and naphthalene concentrations and continued biologic activity within the *°'i x biosparge system's zone of influence. (7|A(xP •5V\0U5*» a ^«ospo . r^ t •2<3KC o f ' >- l*^«»ê^)

• Water depths in the Sheboygan River vary from about 2 feet to greater than 10 feet. 1995-1996 poling data identified a sediment area of approximately 3.4 acres with visible coal tar, sheen, and/or odor (Appendix A, Sheet 3). This area extends about 80 feet upstream of the former upstream (northem) MGP Site property line, as much as 120 feet outward from the shoreline, and about 900 feet downstream of the fonner downstream (southem) propierty line, a short distance past the Pennsylvania Avenue bridge. Tar was evident in sample cores ranging in depth from about 1.5 feet to 9.5 feet.

1665 river ou tech ICr rev 0 final NATURAL RESOURCE

TECHNOLOGY



• Based on the limited 1995-1996 sediment core sampling, the highest total PAH concentrations in the tar/sheen area was 9,294 mg/kg. In two areas without tar observations, PAH concentrations for two samples ranged from essentially non-detectable (ND), 0.09 mg/kg, to 8.1 mg/kg. In nearby areas, both upstream and downstream of the tar/sheen/odor, PAH concentrations ranged from 0.44 mg/kg to 2.17 mg/kg.

1.5 Sheboygan River Characteristics

The Sheboygan River is classified a Class C surface water by the WDNR. Class C surface waters are not

suitable as drinking water sources; however, they are suitable for fishing and fish propagation. Class C

waters are also designated for primary (e.g., swimming) and secondary (e.g., boating) contact recreation.

The River OU is within a portion of the Sheboygan River classified as a warm water sport fish

community (WWSF). (A WWSF community includes surface waters capable of supporting a community

of warm water sport fish or serving as a spawning area for warm water sport fish.)

The Sheboygan River drains 427 square miles (mi^), with its headwaters located in Fond du Lac County.

Near Lake Michigan, the Sheboygan River is a gaining stream that receives groundwater and surface

water from the Sheboygan area and discharges into Lake Michigan. Near the Site, the river varies from

approximately 130 feet (on either the east or west side of Boat Island) to 300 feet wide (just upstream of

Boat Island). Boat Island is in the approximate center of the river resulting in an east and a west channel

adjacent to the Upland OU. A gauging station active from October 1993 through September 1995

recorded an average flow rate of 177 cubic feet per second (cfs) at the mouth of the river (approximately

one mile downstream from the Upland OU).

During 1995 and 1996 sediment investigations (described in Section 3.2.2), an assumed river water

elevation of 582 feet msl was used as a datum for sediment poling activities. This elevation was based on

the USGS topographic quadrangle which indicates the water level in Lake Michigan outside of the

Sheboygan Harbor is approximately 580 feet msl. The river bed elevation within the River OU ranges

from approximately 571.7 to 580.0 feet msl based on the poling data. Water depths within the River OU

ranged from approximately 2 feet to greater than 10 feet.

Flow of the Sheboygan River is generally easterly, toward the lake, but southerly past the Site and is

controlled by upstream dams located at Sheboygan Falls and Kohler. The USGS operated two automated

stream gauging stations: one near Interstate Highway 1-43 (cunently operational) and the other near the


TECHNOLOGY



river mouth (no longer in operation). The stream flow data discussed below was collected from

Hydrologic Station # 040860041, located at "Sheboygan River al Mouth at Sheboygan, Wl." The station

was located over one mile downstream of the WPSC Site, with conditions similar to those of the river at

the Site.

Daily mean discharge data between October 1993 and September 1995 are summarized below:

During 1993 to 1995, highest average daily flow rate (581 cfs) occuned in March. The lowest average

daily flow rate (50 cfs) occuned in September. The variability in water levels and stream flow in the

Sheboygan River is the result of both snowfall accumulation (and the resulting spring mn off) and

precipitation during late spring/eariy summer.

The 1991 FEMA map indicates the 100 year floodplain is at Elevation 584 msl.

1.6 Dredging History

The U. S. Army Corps of Engineers (USAGE) Detroit District is responsible for maintaining a navigation

channel and tuming basin within the river downstream of the MGP Site. The upstream limit of the

USAGE navigation channel is located approximately 500 feet downstream of the MGP Site, just below

the Pennsylvania Avenue Bridge. From the Pennsylvania Avenue Bridge and extending approximately

2,300 feet downstream to near the Eighth Street Bridge, the channel has a project depth of 15 feet. The

remainder of the navigation channel (4,200 feet) downstream to the harbor has a project channel depth of

21 feet.

The Sheboygan Harbor was constructed at the mouth of the Sheboygan River in the early 1920s. In 1954,

part of the lower Sheboygan River (the channel upstream of the Eighth Street Bridge) was added to the

Sheboygan Harbor. The channel above Eighth Street (over 3,000 feet downstream of the MGP Site) was

dredged in 1956. No further dredging occuned. Between 1956 and 1969, a total of 404,000 cubic yards

of sediment were dredged downstream of the Eighth Street Bridge.

Maintenance dredging of the Sheboygan harbor last occuned in 1991 (1995, WDNR, Sheboygan River

RAP). Dredged materials were disposed of south of the harbor as part of a beach nourishment project.

According to the USAGE Detroit District web site, no dredging is planned in the Sheboygan River in

2007.

According to a June 2005 USAGE bathymetric survey of the Sheboygan River, water depths are much

shallower than the USAGE project depths. In this June 2005 survey, observed water depths within the 21

foot project depth portion of the channel were between 5 and 15 feet, while observed water depths within

the 15 foot project depth portion of the channel were between 4 and 7 feet.


TECHNOLOGY



NRT is unaware of any historic public or private dredging activities or bathymetric surveys upstream of

the Pennsylvania Avenue Bridge in the area of the River OU.

2.2 Remedial Investigation

An extensive remedial investigation (RI) was conducted on the Sheboygan River and Harbor. The initial

focus was on sediment and fish tissue sampling within the Sheboygan Harbor. In 1977, WDNR's routine

fish tissue sampling results reported elevated polychlorinated biphenyl (PCB) concentrations which

prompted USEPA and USAGE sediment sampling efforts. Sedimeni sample results reported elevated

concentrations of arsenic, lead, zinc, chromium, and PCBs. Beginning in 1987, Blasland, Bouck, & Lee,


RESOURCE

TECHNOLOGY



Inc. (BBL), on behalf of Tecumseh Products Company, initiated sediment sampling within the Sheboygan

River to evaluate PCB concentrations.

Groundwater at the Tecumseh plant, floodplain surface soil, water column and water fowl were sampled.

RI sampling results showed the upstream sections of the Sheboygan River are the source of PCB

concentrations observed in downstream sediment and water column samples (May 1990, BBL).

2.3 Risk Assessments

Human health and ecological risk assessments (aquatic and tenestrial) were performed by USEPA,

WDNR, and Tecumseh. These assessments concluded the main contaminant of concem in the Sheboygan

River and Harbor is PCBs. Metals also present a risk, however these concentrations are co-located with

PCBs.

The potential pathways of exposure were considered to be dermal contact, ingestion of contaminated

surface water or sediment, and consumption of fish contaminated by sediment. Due lo PCBs, the human

health pathway presented the primary risk at the Sheboygan River and Harbor Site. This risk was based

on the consumption of contaminated fish and nol dermal contact.

2.4 Sediment Transport Study

A Sedimeni Transport Study of the Lower River and Inner Harbor was perfonned to evaluate potential

deposition in the Inner Harbor (November 1996, BBL). The study focused on natural processes burying

contaminated sediments and assessed the feasibility of natural capping/recovery in the Inner Harbor. The

model was not intended to be a comprehensive chemical fate and transport study.

The analytical data showed the maximum PCB concentrations were generally at depth. Near surface PCB

concentrations were generally low, due to the depositional effects in the Inner Harbor. Therefore, the

modeling effort was used to evaluate the natural sedimentation processes and compared that with the

potential for future high-flow events lo erode the deposited material.


TECHNOLOGY



Extreme event simulations (i.e., 100-year flood) modeled with HEC-6 predicted the Inner Harbor is

expected to provide long-term stability and protectiveness. Relatively minor net scour (up to 1 foot) was

predicted in the vicinity of the Pennsylvania Avenue and against erosion. These scour events are nol

anticipated lo result in higher PCB exposures because the higher PCB concentrations are found at 4 feet

below the 1997 sediment surface level.

2.5 Feasibility Study

Three remediation objectives were listed for the Sheboygan River and Harbor (BBL, April 1998):

• Protect human health and the environment due to PCBs attributed to the Sheboygan River and Harbor Site;

• Mitigate potential PCB sources to the Shebogyan River and Harbor system and reduce PCB transport within the river system; and

• Remove and dispose of Confined Treatment Facility/Sediment Management Facility sediments and previously armored/capped PCB-contaminated soft sediment deposits.

To achieve these remediation objectives, the Feasibility Study contemplated the removal of PCB-

contaminated soft sediment so the average surface-weighted average concentration (SWAC) of PCBs in

the Sheboygan River is 0.5 parts per million (ppm).

Several remedial altematives were evaluated. Sediment altematives ranged from no action, monitored

natural recovery, sediment removal, and capping. Each altemative was compared to the nine criteria

described in 40 CFR Part 300.430.

2.6 Record of Decision

The Record of Decision (ROD) for the Sheboygan River and Harbor was issued by USEPA in May 2000.

Selected remedies include sediment removal in the Upper River, additional characterization and

monitoring in the Middle River, and additional characterization and potential removal subject to natural

and recreational disturbances in the Lower River and Inner Harbor.


TECHNOLOGY



Long-term monitoring of the remedial actions includes fish and sediment sampling to ensure achievement

of the SWAC tliroughout all of the Sheboygan River. In addition, the Lower River and Inner Harbor will

have annual bathymelric surveys lo identify areas susceptible lo scour. The USAGE'S most recent

bathymetric survey was performed in June 2005 (Condition of Channel for the Sheboygan Harbor in June

2005).

Applicable or Relevant and Appropriate Requirements (ARARs) and requirements To Be Considered

(TBCs) are provided beginning on page 88 of the ROD.

2.7 Schedule

According to the Fact Sheet, updated February 2007, for the Sheboygan River and Harbor Site (EPA

Identification number WrD980996367), Phase 11 Upper River soft sediment dredging operations were

performed in June 2006 through November 2006. Additional dredging in Phase II is to be performed in

May 2007 and is anticipated to go through October 2007. A total of 21,000 cubic yards (CY) of PCB

contaminated sediment is planned for removal in the Upper River.

Additional sample collection and characterization of soft sediment deposits for the Middle River, Lower

River, and Inner Harbor also will be performed in the summer of 2007. A schedule for addressing

sediment in the Inner Harbor was not mentioned in the Fact Sheet. Depending on the findings of

additional characterization in the Middle River and Lower River, the soft sediment deposits within the

Lower River may also require removal. The River OU of the former Campmarina MGP Site is located at

the downstream end of the Lower River.

3 PREVIOUSLY PERFORMED RIVER OU INVESTIGATIONS AND RESULTS

The following sections summarize known sediment investigations performed near or within the River

OU. Specific discussions regarding contaminant exposure pathways are included in Section 4.

3.1 BBL-1990

Beginning in 1987, BBL conducted sediment sampling for PCBs, VOCs, PAHs, and metals as part of the

Sheboygan River and Harbor Remedial Investigation. Sampling methodologies and results are detailed in

the Remedial Investigation/Enhanced Screening Report - Sheboygan River and Harbor (May 1990,

BBL). Fifteen (15) sediment samples were collected along the length of the river, with 10 samples being

collected above the Pennsylvania Avenue Bridge and 5 samples downstream of the bridge.

A number of sediment samples were collected near or just downstream of the MGP Site (sample locations

are provided in Appendix C). Three samples, R-98, R-lOO, and H-20, had oil or concentrations of PAHs.

Sample R-98 was collected near the downstream end of Boat Island and the sediment was described as

"oil saturated" from 2 to 6 feet below the sediment surface. Sediment samples R-lOO and H-20 were

collected immediately downstream of the Pennsylvania Avenue bridge. Sample R-lOO was described as

"oil saturated" from 4 to 6 feet below the sediment surface; however, neither sample R-98 nor R-lOO were

analyzed for PAHs. Sample H-20 was described as "oil saturated" from 4 to 16 feet below the sediment

surface and had a total PAHs concentration of 70 ppm in the 2 to 4 foot sediment sample. There was no

mention of elevated PAHs downstream of sample location H-20 and no mention of oil saturated

sediments was noted for samples R-99 andR-101, collected on the west side of Boat Island, opposite the

fonner MGP (May 1990, BBL).

3.2 WDOT-1993

In 1993, river sediment sampling was perfonned for the Wisconsin Department of Transportation

(WDOT) construction project on the Eighth Street Bridge. The bridge is located approximately 3,000 feet

downstream of the MGP Site (1993, RMT). PAHs were found in the sediments around the Eighth Street

Bridge in concentrations ranging from 5 to 97 ppm in the top 0 to 2 feet of sediment.

3.3 WDNR-1995

In Febmary 1995, WDNR collected one sediment sample within the River OU, approximately 20 to 30

feet from the shoreline, close to the downstream end of Boat Island (October 1995, WDNR). This sample

contained apparent coal tar and was analyzed for PAHs.

3.4 NRT-1998

NRT performed preliminary sediment investigations for WPSC in 1995 and 1996. Results are detailed in

the Sediment Investigation Report dated Febmary 26, 1998. Sediment sampling focused on identifying

the preliminary nature and extent of MGP residuals in river sediments or natural soil (parent material)

underlying the Sheboygan River. Sediment/soil samples were collected from as deep as 10.5 feet below

the bottom of the river, although in some locations parent materials were encountered beneath the soft

sediments, and this material was also sampled.

Further details regarding the methods for locating, poling, and sediment sampling are included in the

Sediment Investigation Report. The analytical results from NRT sampling efforts are tabulated in

Appendix B of this Technical Letter Report on Table 1 (Field Observations at Sediment Sample

Locations), Table 2 (Sediment Analytical Results - PAHs), Table 3 (Sediment Analytical Results -

BTEX), and Table 4 (Sediment Analytical Results - Cyanide, Phenol, Oil & Grease, Resource

Conservation and Recovery Act (RCRA) Metals & PCBs). Appendix A, Sheet 3 provides a summary of

the distribution of these constituents and the visual observations made during preliminary investigation

activities. Appendix B, Plate 2 provides cross sectional details of river sediment investigations and

Appendix B, Plate 3 provides a contour map of the depth to tar found in river sediments. The following

sections summarize the results of the NRT 1995 and 1996 activities.

River OU-Technical Letter Report - Campmarina Former MGP



3.4.1 October 1995 Investigation Activities

During October 1995, NRT performed an initial sediment investigation to determine the absence/presence

of MGP residuals in the surficial soft sediments (unconsolidated non-parent material). The study

indicated the presence of benzene, toluene, ethylbenzene, and xylenes (BTEX) and PAHs in sediments

within the River OU, adjacent to, and downstream of, the Upland OU (November 1998, NRT).

The sample collection and screening methods are described in the Sediment Sampling Work Plan, Former

Sheboygan II Manufactured Gas Plant Site, Sheboygan, Wisconsin (August 1995, NRT). NRT conducted

the initial sediment sampling with a manually driven Ogeechee'' ' corer and a Ponar''"' grab dredge

sampler. The longest sediment core collected using the Ogeechee''''*^ corer was approximately 30 inches

long, while the Ponar^"^ grab dredge sampler typically collected the top six inches of sediment.

Six transects, consisting of 22 sample locations, were completed. These transects were identified as T701

through T706 and the sampling locations were labeled SD-701A through SD-706C (Appendix A, Sheet 3).

The following is a summary of field observations from the initial investigation:

• All six sediment sample transects showed indications of either odor or tar. Sediment samples SD-702A & B and SD-703A (Appendix A, Sheet 3) exhibited odors in sediments recovered in the hand-core samples. The samples were located within 25 feet of the shoreline.

• Sediment samples SD-701 A, SD-703B, SD-704A & B, SD-705A, B, & C, and SD-706B (Appendix A, Sheet 3) all exhibited coal tar in sediments recovered in the hand-core samples, or on the sounding pole (used to evaluate the depth of sediments present at a given location). These samples were within 20 feet of the shore at SD-701 and within 60 feet of the shore at SD-704 and SD-706. In transects T703 and T705, tar was noted 70 feet and 100 feet, respectively, out from shore.

3.4.2 November 1995/June 1996 Investigation Activities

Following the October 1995 study, NRT conducted a detailed field investigation in November 1995 and

June 1996 to evaluate the distribution of MGP constituents and sediment characteristics. A summary of

the field investigations, results, and recommendations is provided in the Sediment Investigation Report

(November 1998, NRT). A vibrocore sediment collection technique was used to collect the sediment

samples.


TECHNOLOGY




Twelve transects were selected at locations starting approximately 375 feet upstream to approximately

900 feet downstream of the former MGP (Appendix A, Sheet 3 and Appendix B, Plate 2). The October

1995 transects were overlapped and extended. The new transects were identified as T701 through T712

and the sampling locations were labeled SD-701BV through SD-712BV. The transects did not extend

west past Boat Island to the river channel opposite the former MGP.

The following is a summary of findings from the November 1995 and June 1996 field investigations:

• Numerous sediment cores exhibited tar, sheen, or odors within 125 feet of the shoreline, as shown on Sheet 3 in Appendix A. Visual observations of tar, sheen, or odors extended approximately 1,300 to 1,600 feet along the shore beginning approximately 90 feet upstream of the former WPSC property boundary, along the former MGP (approximately 580 feet), and extending approximately 900 feet downstream of the former WPSC property boundary.

• Based on the depth at which tar and animal hair (the suspected source of animal hair is the former upstream tannery) were observed within the sediment, tar and animal hair were covered by natural sedimentation processes. Little river scour was observed through certain sections of this segment of the river. The depth to tar from field observations (Appendix B, Table 1) is shown on Appendix B, Plate 3. These field observations showed a thin layer where the tar is located within 1 foot of the sediment surface. Further downstream, past Center Avenue extended (i.e., approximately the southem property line of the former Campmarina MGP), tar was found more than 2 feet below the sediment surface.

• The sediment core logs showed approximately 2 lo 10 feet of soft river bottom sediments, including silt, sand, and organic material. No aquatic plants were found at any of the sample locations. The soft upper sediment layer is underlain by native glacial sediments, characterized by sands and red brown clay till.

3.5 Chemical Constituents in Sediment

The sediment sampling locations and PCB analysis conducted by BBL for the Sheboygan River and

Harbor RI, related to the Campmarina River OU, was summarized on a figure included in Appendix C.

A summary of the NRT analytical results from the 1995 and 1996 sediment sampling events are provided

in Appendix B, Table 2 (PAHs), Table 3 (BTEX), and Table 4 (metals, cyanide, PCBs, phenol, oil and

grease, and TOC). A distribution of BTEX and total PAH concentrations at each sample location is


TECHNOLOGY




provided in Appendix A, Sheet 3. Laboratory results from the 1995 and 1996 Site investigations show

low concentrations of PCBs, RCRA metals, cyanide, and phenol.

3.5.1 BTEX and PAH Results

Total BTEX ranged from ND to 710 ppm, while total PAHs ranged from ND to 9,294 ppm, in sedimeni

samples collected and analyzed by NRT. Generally, high concentrations of BTEX co-occuned with high

PAH concentrations.

Based on the BTEX and total PAH analytical laboratory results, the highest concentrations were found at

depth; as indicated by NRT cores SD-702BV, SD-702CV, SD-704BV, and SD-705BV (Appendix

A, Sheet 3 and Appendix B, Tables 2 and 3). These sediment cores are all located adjacent to, and just

downstream of, the former MGP Site. The depths at which these samples were collected ranged from

approximately 2 lo 10 feet below the sediment surface. The deepest occunences of tar were present in

transects T704 and T705.

As discussed in Section 3.1, BBL also collected a sediment sample for PAH analysis at location H-20

(Appendix C) (just downstream of the Pennsylvania Avenue Bridge). The sample collected 2 to 4 foot

below the sediment surface had a total PAH concentration of 70 mg/kg (May 1990, BBL).

Visual observations of (Appendix A, Sheet 3) lar, sheen, and odors were found to extend approximately

900 feet downstream of the former MGP; however, the analytical results from sediment sample

SD-71 lAV showed constituents of concem may have migrated only approximately 580 feet downstream.

BTEX and total PAH concentrations in samples downstream of transect T705 (approximately 450 feet

upstream of transect T7] 1) are significantly lower than the concentrations reported in samples from

transects T702, T704, and T705, which were immediately adjacent to the fonner MGP. Additionally, the

results showed that sediments with MGP residuals, especially downstream of transect T705, were buried

below other non-native sedimeni (Appendix B, Plate 2 and 3). Sedimeni samples collected upstream of

the former MGP (from SD-708AV & BV and SD-709AV), and approximately 900 feet downstream

(SD-712AV and BV) of the former MGP, did not exhibit elevated BTEX or total PAH concentrations.


TECHNOLOGY




3.5.2 Metals Results

NRT submitted three samples from its preliminary sedimeni investigations for laboratory analysis of

RCRA metals (Appendix B, Table 4) from locations where animal hair (suspected tannery waste) was

present. Sample results showed generally low levels of metal constituents (Appendix B, Table 4).

Chromium and lead contamination are common constituents associated with tannery wastes.

Concentrations of chromium and lead were detected ranging from 7.4 to 500 ppm and 28 to 140 ppm,

respectively. No other sedimeni samples were characterized for metals.

Table 1 of the ROD issued in May 2000 by USEPA for the Sheboygan River and Harbor Superfund

Project indicates that metals contamination ranges from non-detect to 300 ppm in the Upper, Middle, and

Lower river sections. Maximum concentrations of chromium and lead detected were 143 ppm and 293

ppm, respectively.

3.5.3 PCB Results

NRT submitted three samples for laboratory analysis of PCBs (Appendix B, Table 4). The PCB

concentrations detected in the sediment samples from the Site ranged from 0.42 ppm lo 2.3 ppm.

PCB concentrations found upstream of the former MGP, as part of the Sheboygan River and Harbor

Superfund Project (October 1995, WDNR), ranged between non-detect up lo 4,500 ppm. PCB

concentrations detected adjacent to the former MGP Site as part of the BBL 1987 investigation (samples

R95, R99, RlOl, and R98) ranged between non-detect up to 2.3 ppm (May 1990, BBL). PCB

concentrations detected downstream of the MGP Site as part of the BBL 1987 investigation (sample

RlOO) ranged between non-detect up to 67 ppm (May 1990, BBL) (Appendix C).

3.5.4 Cyanide and Phenol Results

Thirteen sediment samples were analyzed for total cyanide, weak acid dissociable cyanide, and phenol in

October and November 1995 (Appendix B, Table 4). There was no blue/black sheen and/or blue/black

wood chips were observed in the sediments. The total cyanide were detected in 5 of 13 sediment samples

at concentrations ranging from 0.59 to 8.7 ppm. Weak acid dissociable cyanide was detected in 3 of 13

1665 river ou tech Itr rev 0 final NATURAL R E S O U R C E

T E C H N O L O G Y




sediment samples at concentrations ranging from 0.51 to 3 ppm. Phenol was present in only 4 of 13

sediment samples at concentrations ranging from 0.19 to 48 ppm.

Cyanide and phenols were not tested for as part of the Sheboygan River and Harbor Superfund site

investigations, as such no data is available for these contaminants.

3.6 Chemical Constituents in Surface Water

Surface water chemistry data for conventional pollutants (i.e., nutrients, solids, bacteria, etc.) are collected

on a nearly monthly basis in the Sheboygan River at the Esslingen Park sampling location by the WDNR.

Esslingen Park is located approximately 1.5 miles upstream of the Former MGP Site. PAHs, BTEX,

RCRA metals, PCBs, cyanide, and phenols are not routinely measured in the Sheboygan River.

Table 3 of the USEPA ROD for the Sheboygan River and Harbor Superiiind site (May 2000, USEPA)

showed PCB concentrations in surface water ranged from non-delecl (<0.05 parts per billion [ppb]) to

0.77 ppb during an interim PCB removal action conducted several miles upstream in 1989 and 1990.

4 REMEDIAL ACTIONS PERFORMED

No remedial actions have been performed lo dale in the River OU.

During the 2001 Upland OU soil remediation activities (February 2003, NRT), approximately 670 feet of

river bank was excavated and reconstructed lo provide stmctural support for the geosynthetic cover and

future park stmctures. Excavation operations generally were limited to material above the groundwater

table and/or shoreline. The following activities were conducted to reconstruct the river bank:

• Existing riprap that with a visually clean surface was removed and segregated for reuse;

• An old 30-fool long, ten-inch diameter pipe, mnning parallel lo the river, that connected to a wooden crock, were both removed and properly disposed in a landfill. The pipe and crock exhibited MGP odors;

• The former retaining wall along the river was cut and removed at the approximate river elevation;

• Excavation operations extended lo the planned design 580 feet msl elevation with the exception of one area located midway along the river bank. MGP-related contamination and evidence of coal tar-like materials were observed in soils at approximately 8 to 10 feel bgs in the central portion of EZ-4 excavation. In order to address the area, an 88 feel by 10 feel area was excavated to elevation 578 feet msl. Excavation operations did not extend lower than the 578 feel msl elevation due to the close proximity of the river. The location of the deeper excavation zone is indicated on Sheet C040 in Appendix D;

• Excavation base samples (EZ-401 through EZ-405) were sampled al the 580 feet msl elevation with the exception of EZ-403, which was sampled at approximately the 578 feet msl elevation. The sampling documented the near shore sediment conditions outside the perimeter of the vertical banier wall; and

• The riverbank was restored with filter gravel, stmctural fill, and riprap. Approximately 2 feet of structural fill was placed in the over-excavaied area from elevation 578 feet msl to 580 feet msl. A non-woven geofabric and six inches of filter gravel were placed over the fill along the base of the riverbank (elevation 580 feet). A second layer of filter fabric was placed over the filter gravel followed by stmctural fill that was compacted to restore the river bank at a slope of approximately two feet horizontal to one fool vertical (2H: 1V). Riprap was then placed along the restored river bank as shown on Sheet C040 in Appendix D.

Section 4 - Remedial Actions Performed Page 25 of 30

At EZ-4, the soil/sedimenl quality was analyzed for total BTEX/benzene, total PAHs/naphthaiene and

total cyanide/lead. The results are summarized in Appendix D, Table 2 and Figure 5 and indicate residual

concentrations of benzene, naphthalene, total lead, and total cyanide. These residual concentrations are

effectively capped with up to 6 feel of clean compacted stmctural fill. As stated in the Documentation

Report (Febmary 2003, NRT), the remaining material will be considered as part of future sediment

management work.

5 IDENTIFIED RIVER OU PATHWAYS AND CONCLUSIONS

As discussed in Seciion 1.1, remedial actions have been performed in the Upland OU and assessment of

the appropriate Upland OU exposure pathways are discussed in the Upland OU Technical Letter Report.

5.1 River OU Potential Exposure Scenarios and Receptors

A qualified risk assessor will perform a Site reconnaissance to assist in developing the Work Plan (WP)

for the River OU RI. As part of the Site reconnaissance, a biological habitat assessment will be

performed and the sunounding land use and access to the River OU will be noted. The results of the Site

reconnaissance will be used to refine the Campmarina River OU CSM.

Potential exposure scenarios and receptors to be evaluated in the River OU WP include:

5.1.1 Recreational Land Use Scenario - Visitor/Trespasser

A visitor may be potentially exposed to constituents of potential concem (COPCs) in surface water and

sediment while swimming, wading, fishing, or boating in the Sheboygan River, adjacent to the former

MGP facility. The potential exposure scenarios to be evaluated include incidental ingestion and dermal

contact with surface water and/or sediment from the Sheboygan River.

5.1.2 Benthic Invertebrates - Aquatic Ecological Receptor

Benthic invertebrates form the base of many food chains and spend most or all of their life-cycle

burtowed or feeding just at the interface between surface water and sediment. Benthic invertebrates may

be potentially exposed to COPCs in surface waler and sediment in the Sheboygan River, adjacent to the

former MGP facility. The potential exposure scenarios to be evaluated include ingestion and dermal

exposure with surface water and/or sedimeni from the Sheboygan River.


TECHNOLOGY



Section 5 - Identified River OU Pathways and Conclusions Page 27 of 30

5.1.3 Other Ecological Receptors

Other species may be exposed to COPCs in sediment and/or surface water from the Sheboygan River.

The need to carry forward additional ecological receptors from higher trophic levels (e.g., fish) will be

evaluated based on the biological habitat assessment and the results from previously collected chemical

concentrations in surface water and/or sediment. If the biological habitat assessment indicates there is

limited habitat area within the Sheboygan River adjacent to the former MGP facility, additional

ecological receptors will not be canied forward.

5.2 Additional Data Needs Summary

Additional River OU RI activities will focus on the following objectives:

Evaluate the nature and extent of MGP residuals in near-shore sediment; i • ^ F ' "

Assess potential human health and ecological risk related to MGP residuals in sediment;

Evaluate the nature and extent of non-MGP related constituents;

Perform river water sampling lo evaluate if conditions exist that may pose a risk to human health and the environment;

Evaluate whether Boat Island wananls characterization;

Collect additional Site data to support a feasibility study; and

If a remedial action is necessary, establish acceptable remediation goals.

As described in Section FV, Task 1(B) and (C), the above work elements will be discussed in a Technical

Scoping Meeting to be held within seven to fourteen business days after submitting this River OU

Technical Letter Report. The River OU Work Plan will be submitted within 90 days of receipt of the

Technical Scoping Meeting summary. A River OU project specific schedule for RI/FS tasks will also be

included in the RI/FS Work Plan.

3: Sediment Management Standards, Chapter 173-204 WAC, Washington State Department of Ecology. April 1991. The Standards were developed using the Apparent Effects Threshold Approach. The TEC and PEC values for the comopunds are based on no effect and miniiTial effect standards, respectively, from the Washington Standards and are intended to apply to Puget Sound, and estuarine habitat. The values were calculated based on an assumed TOC content in sediment of 1 %.
