PHASE 2 SUPPLEMENTALSAMPLING AND ANALYSIS WORK PLAN

1. INTRODUCTION

Results from the October 2006 supplemental soil sampling event identified the general area ofelevated concentrations of PCBs in soils that might be a source of PCBS identified in theFields Brook sediments. This Work Plan provides for a truck mounted Geoprobe® Rig to beused to further define the location and extent of the PCBs within this area.

This Work Plan is organized as follows:

• History

• Scope of Work

• Sampling Procedures

• Analytical Procedures

• Quality Assurance/Quality Control

• Nomenclature

• Safety

• Project Schedule

2. HISTORY

2.1 2004 Sampling

Annual soil sampling of the Fields Brook sediments and floodplain soils is required as part ofthe Post-Closure sampling requirements for the Fields Brook Superfund Site. In August2004, sediment samples in the brook to the east of State Street indicated the presence of PCBsat concentrations in excess of the Confidence Remov?' Goal (CRG) (established for the Siteremedy) for PCBs of 50 mg/kg. In 2004, one sediment sample (SD16), located approximately130 feet east of State Street, contained 100 mg/kg PCBs. A supplemental investigationperformed in November 2004 included collecting samples at 50 foot intervals both upstreamand downstream of location FBSD16. No other locations contained PCBS in excess of theCRGs. Therefore, in May 2005, the sediments in the area of SD16 were removed and theissue was believed to be an anomaly.

2.2 2006 Sampling

Results from the August 2006 sampling event indicated elevated concentrations of PCBs insediment sample locations SD15 and SD16 (See Figure 1). The sediment samples SD15 andSDI6 indicated PCB concentrations of 130 mg/kg and 92 mg/kg, respectively. The PCBs

Phase 2 - Supplemental Soil Sampling Plan Page 1 of 5

concentrations of samples upstream and downstream of these samples were well within theCRG (5.3 mg/kg at SDH (downstream) and 0.65 mg/kg at SD17 (upstream).

A Supplemental Investigation was performed in October 2006 with two goals:

1) To further delineate the sediment within the brook that exceeds 50 mg/kg.

2) To identify the source of the PCBs. This area of the brook was fully excavated in2001 as part of the Final Remedial Action for the brook. The underlying soilswere removed and clean soils were placed as a foundation for the brook. Thebrook was then lined with a filter fabric and clean cobbles were placed on top ofthe filter fabric. The PCBs that have been identified in the brook have beendeposited in the brook since the Remedial Action was completed.

The data results from the supplemental sediment sampling are provided in Table 1. Severaladditional sediment locations were identified that exceed the Remedial Action CRG of 50mg/kg.

The data results from the soil samples collected in October 2006 are provided in Table 2.Field analysis of the samples was performed using the RaPID Assay immunoassay method byStategic Diagnostics, Inc. For further information on the immunoassay testing and otherdetails of the October 2006 sampling event, see the Site Monitoring Report - SupplementalSoil and Sediment Sampling Performed October 2006 - Fields Brook Superfund Site.

3. SCOPE OF WORK

Soil samples will be collected at approximately 19 locations identified in Figure 2 using atruck mounted Geoprobe® Rig. Each of these locations will be sampled at the 1-foot, 2-foot,and 3-foot depths below ground surface (bgs). Surface samples will not be collected sincethe top one foot of soil is clean soil that was placed as part of the Remedial Action in 2001. Ifvisual observation of the soil core collected indicates that a sample should be pulled from adifferent depth, then that judgement will be made and documented in the field log. If visualobservation indicates soil staining, then another soil boring location (with samples collectedfrom the three intervals) will be established at a location approximately 25 feet towards thedirection that is assumed to be clean. If samples south of the Millenium fence line are needed,then contact Bob Rule for direction on how to obtain access.

The samples will be packaged and transferred to CompuChem Labs in Gary, North Carolinafor PCB analysis using EPA Method SW846-8082.


3.1 Sampling Procedures

The Geoprobe* will be advanced once at each location to a three-foot depth. Samples will becollected using acetate liners that will be pushed to the desired depth into the subsurface by aGeoprobe* rig. The soil boring (contained within the acetate liner) will be pulled and laid outon a clean surface (such as visqueen). Visual observations of the soil characteristics will bedocumented in a logbook. At least one discreet sample will be collected from each 1-footsection of soil to represent that section. Additional samples may be collected as appropriatefor properly characterizing contaminant conditions in the area. The sample number willdocument the lowest point of the soil interval that is selected for sampling, as explained inSection 3.4(4). As each interval is sampled, Moisture content will also be documented foreach sample interval in terms of dry, damp, moist, or saturated to determine the firstoccurrence of groundwater. Site conditions, sample locations, observations, and times, andother relevant information will be recorded in the field sampling log book maintained for theevent.

Sample containers will be provided by the laboratory (as provided for in the approved SiteQAPP). All samples to be sent to the laboratory will be transported as required by the QAPP.The sample containers will be filled, sealed, labeled, and placed in coolers. The samples willbe stored at 4 °C (± 2 °C) and shipped to the laboratory via overnight delivery.

3.2 Laboratory Analytical Procedures

Soil samples will be analyzed for PCBs (EPA Method SW846-8082) by CompuChem Labs ofGary, NC. Additional analyses may be performed based on field observations. The analyticalmethod, the laboratory method detection limits, and the laboratory-specific analytical standardoperating procedure are approved in the Project QAPP.

3.3 Quality Assurance/Quality Control

QA/QC samples will be collected at the following frequency:

• Duplicate samples will be collected for the field analysis at a rate of 1 duplicate per 10samples collected.

• MS/MSD samples will be collected for the soil samples at a rate of 1 per 20 fieldsamples.

• If dedicated equipment is not used and equipment decontamination is requiredbetween samples, then field equipment blanks will be collected at a rate of 1 blank per20 samples.


3.4 Nomenclature

The unique identification numbers will be assigned in agreement with the approved QAPP, asfollows:

1) The first two characters of the sample identification code will identify the projectas "FB".

2) The next two characters of the sample identification code will identify the sampleas a soil sample, where SS is used to designate soil samples.

3) The next two characters of the sample identification code will identify the locationwith a number, starting with the number 70, and increasing (e.g., SS70, SS71,SS72...)

4) The next two characters, preceded by a hyphen (-) will represent the lower-mostdepth of the sample core, in inches, where "12" would represent the samplecollected from 12-inches bgs, etc.

5) The final four characters, preceded by a hyphen (-) will represent the month andyear of the sampling event, in the format of-MMYY, where MM identifies themonth that the sample is collected and YY identifies the year. An exampleidentification number for soil sample SS71 in a sampling event performed inDecember of 2006 is "SS71-12-1206".

6) Quality control samples will be identified as follows:

a) SS-DUPX, or SD-DUPX are used for field duplicates, where X is anumber, increasing with each duplicate sample collected in that event, andfollowed by -MMYY, where MM identifies the month that the sample iscollected and YY identifies the year. An example identification numberfor the second duplicate soil sample collected in an event on December15th of 2006is"SS-DUP2-1206";

b) EBX is used for Equipment Blanks, where X is a number, increasing witheach field blank sample collected in that event, and followed by -MMYY,where MM identifies the month that the equipment blank sample iscollected and YY identifies the year. An example identification numberfor the second equipment blank sample collected in an event on December15th of 2006 is "EB2-1206"; and

c) Matrix spike/matrix spike duplicate samples will be identified identical tothe sample identifier for the original sample from the location. Thesesamples will appear as additional samples from that location.


4. SAFETY

The work planned is located in an industrial area directly north of Millennium Chemicals.This facility manufactures Titanium oxide (TiO:) and Titanium tetrachloride (TiCl4). WhenTiCU contacts water, chlorine gas forms. Releases of the chlorine gas have been known tooccur from the Millennium Chemicals facility.

An Addendum to the Project Health and Safety Plan specifically to address work in this areais attached as Appendix A to this plan.

5. REPORTING

A final report will be prepared providing a brief description of field sampling procedures andinformation on field observations made during thje sampling activities, tables presenting thelaboratory results, and copies of the data verification reports and laboratory results. Dataverification will be performed following the approved Project QAPP guidelines.

2. Locate spoils, other materials, and equipment at least 2 feet from the side of theexcavation area (or brook)

Work Zones

1. Clearly delineate exclusion zone (EZ), contamination reduction zone (CRZ), or accesscontrol points, and support zone.

2. Limit access to EZ, CRZ and control points.

3. Maintain a log of all individuals entering the EZ.

Personnel Protective Equipment (PPE)

As defined by the Site HASP, Modified Level D PPE will be required for the work, including:

1. Tyvek, poly coated preferred due to wet conditions

2. Chemical resistant gloves, and Chemical resistant over boots.

Decontamination Procedures

Decontamination prevents the spread of potentially contaminated material from the work zones.

Personnel Decontamination

The following decontamination procedure will be used:

1. Remove boots and outer gloves

2. Remove coveralls (if worn)

3. Remove inner gloves

4. Wash hands, face and neck

Rinse waters from decontamination will be collected for disposal in the 300 gallon tank at FieldsBrook Landfill. PPE will be containerized and disposed at an approved off-site facility.

Equipment Decontamination

Equipment that comes into contact.with the soils will be thoroughly washed with soap and water.Water used for decontamination will be collected for disposal in the 300 gallon tank at Fields BrookLandfill.

To minimize tracking soil on the roads, all equipment leaving the site will be clean and free of soil ormud.

Millennium Chemicals

The work planned is located in an industrial area directly north of Millennium Chemicals. Thisfacility manufactures Titanium oxide (TiOi) and Titanium tetrachloride (TiCU). When TiCU contactswater, chlorine gas forms. Releases of the chlorine gas have been known to occur from theMillennium Chemicals facility.

Chlorine gas is dangerous even for short exposures. The gas has an irritating and pungent odor and isirritating to the nose, throat, and lungs. If an exposure has occurred, transport the affected individualimmediately to the Ashtabula General Hospital (Figure 1). A representative from MillenniumChemicals is present at the hospital after all facility releases.

In the event that a release occurs, and alarm will be sounded. The Millennium Chemicals alarms areas follows:

Minor Alarm - a continuous high pitch siren. Minor alarms indicate an alarm for inside thefacility that should not affect the area outside the property line.

Major Alarm - a High/low wavering siren.

IF A MAJOR ALARM IS SOUNDED - DON THE PROVIDED ESCAPE PACK AND NOTETHE WIND DIRECTION. TURN OFF ALL IGNITION SOURCES AND GET INDOORSIMMEDIATELY.

All Clear - Westminster Chimes

NOTE

Millennium Chemicals tests these alarms even' Friday at 9 am and 11 am.
