Davis Timber Site Remedial Investigation Work Plan Phase 2 February 23, 2001

LO FIELD SAMPLING AND ANALYSIS PLAN - PHASE 2

Phase 2 ofthe this remedial investigation will include the collection of soil/waste and perched ground water samples from on site and sediment/soil samples fi^om off site. The types and locations of these samples were based on data gaps identified during phase 1 ofthis investigation. The estimated number of samples for phase two is shovsoi in Table 1.1. However, field personnel will be responsible for the final selection ofthe sampling locations which may have a slight impact on the type and number of samples collected. All ofthe samples collected will be analyzed for extractable organic compounds and dioxin/dibenzoflirans. The soil/waste samples collected on site will also be analyzed for poly chlorinated biphenyls (PCBs). The sediment samples collected offsite will be analyzed for total organic carbon and grain size. The site background and physical setting, and an initial site evaluation were presented in the Phase 1 Work Plan. Consequently, they will not be repeated in this document.

1.1 Sample Identification

Samples collected during the project will be designated using an eight digit alphanumeric code in the form of DT-XXX-YYY. The prefix "DT" (for Davis Timber) will be used on all sample designations. The "XXX" represents a three digit alphanumeric sample number corresponding to the sample collection location. The sample collection locations are specified on the Figures presented in sections 1.1 through 1.4 In general, the samples will be numbered as follows:

001-199 - On site sample 201 -299 - Offsite samples 701 - 799 - Replicate (spHt) sample 901 - 999 - QA/QC samples

The last two dighs ofthe repHcate will, in general, correspond to the sample coUection location. For example, sample DT-762-SLA is a repHcate of sample DT-062-SLA

Other letter designations may be assigned as conditions warrant.

To insure the continuation ofthe proper numbering sequence throughout the project, the SESD FORMS computer program will be used. The project numbers will be assigned at a later time. The account numbers that will be used by the field personnel through out the field sampling portion of the investigation will be 50102DA4P6CO.

1.2 Impoundment Delineation and Soil/Waste Sampling

The location ofthe fonner on site impoundment was determined during phase 1 ofthis mvestigation; however, the extent was not delineated because the area had been covered with tree bark and wood chips. The south and west borders ofthe impoundment appear to be the edge of the tree bark fill material. The north and east boundaries were not identifiable because the tree bark fill extends over much ofthis portion ofthe site.

The north and east boundaries ofthe impoundment will be delinieated using direct push technology (DPT). A GeoProbe wiH be used to advance boreholes and coUect samples ofthe tree bark fill down into the former unpoundment and through to native material along four transects (see Figure 1.1). Two ofthe transects will be perpendicular to the east boundary and two will be perpendicular to the north boundary. Boreholes will be spaced every 25 feet along the transect until the edge of the impoundment is encountered.

donnfa/davtsArans


Samples will be coUected from each borehole at five foot intervals until native material is encountered. The tree bark is expected to be between two and twenty feet thick. The former impoundment is expected to be five feet thick. The samples vAW be visually inspected and screened using field PID and FID air monitoring instruments. Up to six samples collected from the tree bark fiU and the fonner impoundment will be submitted for extractable organic compound, PCB's and dioxin/dibenzofuran analyses. Additional boreholes may be advanced along the south and west borders ofthe tree bark fill to verify the extent ofthe former impoundment in those directions.

1.3 Trench Location and Soil/Waste Sampling

Discussions with area residents during the August 22, 2000 public meeting revealed the possibility that trenches were dug along the southem portion ofthe site into which waste pentachlorophenol (PCP) and material from the impoundment was placed and buried. The GeoProbe will be used to advance boreholes in this area to determine if and where trenches may exist. If non native material is encountered, up to four samples from different boreholes will be collected an submitted for extractable organic compound, PCB's and dioxin/dibenzofuran analyses. A Geonics EM-31 may also be used to dehneate the trench boundaries. Grid lines will be set up on a north-south east-west basis with readings taken at 25 foot intervals.

1.4 Sediment Sampling

Sediment samples collected fi'om East and West Mineral Creeks during Phase 1 ofthis investigation indicated that contamhiant concentrations decreased with distance from the site toward Country Club Estates Lake. To further characterize the creeks and defme the areas of contamination, sedunent samples will be collected from 8 additional locations. Four locations wiU be from West Mineral Creek and four locations from East mineral Creek. The locations in East Mineral Creek wiU be spaced every 200 feet dovm stream from phase 1 sample location DT-EMC-SDl. In West Mineral Creek one location v̂ U be between phase 1 locations DT-WL-SD2 and DT-WMC-SDl. The remaining three locations will be spaced every 200 feet down stream fi-om phase Isample location DT-WMC-SDl (see Figure 1.2).

The sediment samples v^ll be collected using a zero to three inch interval below the water-sediment interface. The sediment samples will be analyzed for extractable organic compounds, PCB's, dioxin/dibenzofuran, total organic carbon and grain size.

1.5 Temporary WeU InstaUation and Sampling

During the Phase 1 investigation, h was noted that a perched water table existed in the tree bark fill material over lymg the former unpoundment. To characterize the perched ground water, up to three temporary wells will be installed and sampled during this investigation. The exact location of these temporary wells will be determined in the field. The ground water samples fi-om the temporary weUs will be analyzed for extractable organic compounds, PCBs and dioxin/dibenzofuran.

2.0 PHASE 2 REMEDIAL INVESTIGATION SAMPLING/DATA QUALITY OBJECTIVES

2.1 General Remedial Investigation Data Quality Objectives

General remedial investigation sampling objectives as well as the data quality objectives were presented in the Remedial Investigation Work Plan for Phase 1 ofthe Davis Timber Site project. Consequently, they will not be repeated in this document.

2.2 Phase 2 Site Specific Data QuaUty Objectives

2.2.1 Problem

Previous investigations at the Site indicate that on-site soils, perched ground water, and offsite sediments have been contaminated as a result of past facility operations. Elevated levels of dioxin/dibenzofuran isomers, pentachlorophenol (PCP) and extractable organic compounds have been identified but the extent of contamination has not been adequately determined. More specifically, the location ofthe former impoundment has been identified but the size and depth have not been determined. The bark/wood chips overlying the impoundment appear to be holding a significant amount of water which may be contaminated. The contaminant concentration gradients in East and West Mineral Creeks have not been adequately determined and there exists the possibility of waste disposal trenches along the southem border ofthe she.

2.2.2 Objectives

The specific objectives ofthis phase of the investigation include the foUowing:

• Determining the nature of, and the areal and vertical extent of contamination (waste types, concentrations, and, distributions) in the former impoundment and perched groundwater at the Davis Timber Site;

Delineate the contaminant concentration gradients down stream ofthe site in East Mineral Creek and West Mineral Creek.

Determine if waste burial trenches exist on the southern portion ofthe site and if so, determine the waste types, concentrations and distributions.

• I)etemiine if the waste types and concentrations identified exceed Region 4 removal or remediation levels.

Davis Timber Site Remedial Investigation Work Plan Phase 2 Febmary 23, 2001

2.2.3 Data Requirements

Soil/waste, sediment and ground water samples will be required to complete the objectives for phase 2 ofthis mvestigation. Sampling locations wiU be directed to refine the data resuhs from phase 1. Removal and remediation action levels for Region 4 will be developed if any areas exceed regional environmental cleanup goals. Table 2.1 presents the data quality objectives for each media sampled.

2.2.4 Study Boundaries

The study boundaries for this phase ofthe investigation include the Davis Timber site. East Mineral Creek and West Mineral Creek. The contaminants wiU be limited to the compounds contained in the SESDs TCL, TAL, and pesticide target analyte lists. Detection levels will be those obtained with routine analysis.

2.2.5 Contaminant/parameter of Interest

A Hst of contaminants of concem will be prepared as part ofthe Base Line Risk Assessment using data collected during this investigation. Cunently, extractable organic compounds, PCBs and dioxin/dibenzofurans are know to exist at the site. If any contaminants are found to exceed Regional removal/remediation goals, a feasibility study will be conducted to select the appropriate remedy.

2.2.6 Acceptable Decision Error rates

Acceptable decision enor rates will be dependent upon the contaminants of concem developed as part ofthe Base Line Risk Assessment. In order to assure data accuracy, a sufficient number of samples v^ll be collected from the site to determine what, if any contaminants exist at the site. Duplicate samples and quality control samples v̂ all also be collected to vaHdate the field activities and insure that these activities did not introduce contamination or bias sample results. It is expected that 90% of samples collected wUl result m valid results.

2.2.7 Design Optimization

This field investigation has been designed to provide the information necessary to adequately address the stated objectives using a direct-authoritative approach. Data collected during phase 1 identified specific areas contaminated with PCP, extractable organic compounds and dioxin/dibenzofurans. Samples collected during phase 2 v^ll refine the areal extent of these contaminants. Previous sampling resuhs, on she EM surveying, visual observation of Geoprobe samples and air monitoring results during sampling activities will be used to direct sampling locations.

17

Davis Tunber Site Remedial Investigation Work Plan Draft Phase 2 Febmary 23, 2001

5.0 FIELD HEALTH AND SAFETY PLAN

5.1 Purpose

The purpose ofthis safety plan is to assign responsibilities, establish personnel protection standards, establish mandatory safety operating procedures, and provide for contingencies that may arise while conducting this remedial investigation. All aspects ofthe field operations must comply with the US-EPA, Region IV, Safety. Health and Environmental Management Program (4) manual which is consistent with US-EPA Orders 1440.2 and 1440.3) and Occupation Safety and Health Administration regulations (29 CFR 1910.120).

5.2 AppUcation

The provisions ofthis safety plan are mandatory for all EPA personnel and personnel under contract to EPA involved with this investigation. Application ofthis safety plan include the sampling and mitigation undertaken on the she or at anv ofF-site areas which may be affected by containination from the site. All visitors (state, contract, EPA persormel, etc.) will be required to abide by these safety procedures. Reflisal to comply vwth the safety guidelines established will result in the visitors being baned from the she or the suspension of work.

5.3 Responsibilities

The field project coordinator (Dan Thoman) and the safety officer Bobby LevAs will have the primary responsibilities for:

1. Assuring that appropriate personnel protection equipment is available and properly utilized by all field operations personnel.

2. Assuring that field personnel are aware ofthe provisions ofthis plan, are instmcted in the work practices necessary to ensure safety, and in planned procedures for dealing with emergencies.

3. Assuring that personnel are aware ofthe potential hazards associated with the site operations.

4. Supervising the monitoring of safety performance by all personnel to ensure that required work practices are employed.

18

Davis Timber She Remedial Investigation Work Plan Draft Phase 2 Febmary 23, 2001

5. Assuring personnel have had proper safety training before participating in the investigation and have read the US-EPA, Region IV, Safety. Health and Environmental Management Program manual.

6. Conecting any work practices or conditions that may result in injury to personnel or exposure to hazardous substances.

7. Assuring that proper emergency first aid equipment is available (eye wash station, first aid kit, etc.)

The safety officer will have the ultimate authority on all safety decisions and can suspend project operations if required safety procedures are not used by field personnel. In addition, prior to the initiation of work each day, a safety meeting will be held by the safety officer with field personnel to discuss field safety operations.

5.4 Training Requirements

All field personnel must have received a minimum of 40 hours of initial personnel protection training ofF-site. Personnel must also receive cardiopulmonary resuscitation (CPR) and first aid training prior to she entry (which can be included in the 40 hours of personnel protection training). All personnel that have never worked at a hazardous waste site will be accompanied by an experienced employee for at least 3 days prior to being expected to work at the site without direct safety supervision. All certifications of training wiU be on file with the Science and Ecosystem Support Division safety officer as specified in the US-EPA, Region FV, Safety. Heahh and Environmental Management Program manual prior to site entry.

5.5 Medical Monitoring

Prior to site entry all field investigative personnel must under go a baseline medical examination as specified in the US-EPA, Region IV, Safetv. Health and Environmental Management Program manual.

19


5.6 Site Safety Considerations

Previous sampling at the site revealed the presence of pentachlorophenol and dioxin/dibenzofiiran isomers m the soil. Hand augers wall be used during the remedial field investigation. It is possible that during these field operations the liberation of irritating and possibly toxic vapors might occur. However, it is felt that the likelihood ofthis occurring is remote. Regardless, the location ofthe nearest phone, the emergency phone numbers and the route to the nearest hospital wiU be placed in each vehicle. It is the responsibility ofthe safety officer to ensure that all field personnel know the route to the hospital and have a copy ofthe emergency phone numbers.

5.7 Site Monitoring and Routes of Exposure

During various phases ofthe sampling activities, the site may be monitored with a photo ionization detector, an organic vapor analyzer (OVA), a radiation survey meter and a combustible gas meter/oxygen meter. It wiU be the safety officer's responsibility to determine what level of monitoring, if any, will be required for each samphng event. Table 5.1 lists the action levels for -each ofthe air monitoring instmments/meters. If readings on the instmments/meters exceed those Hsted in Table 5.1, then the personnel must discontinue field operations and discuss the findings with the safety officer.

It is felt that pentachlorophenol will consthute the greatest known chemical risk to field personnel. Routes of exposure for these compounds would include inhalation, ingestion and dermal contact. The ingestion route represents minimal risks but the inhalation and dermal routes present possible risks. Therefore, the safety officer will determine what levels of protective clothing will be worn by field personnel to eliminate these risks.

5.8 Protective Clothing

Levels of protection refened to in the subsequent sections are defined in the US-EPA, Region IV, Safetv. Health and Environmental Management Program manual.

5.8.1 Protective Clothing/gloves

All personnel wall have Level D protective clothing available to wear. The protective clothing and gloves required to be wom wUl be mandated by the safety officer and may differ from one sampling location to the next.
