1 Project Description This Data Management Plan (DMP) provides the data management processes and procedures for the performance of work activities associated with data collection for the Response Action Oversight task order for the GE-Pittsfield/Housatonic River Site (“Site”) located in Pittsfield, Berkshire County, Massachusetts.

The Response Action activities at the Site, in accordance with the October 2000 Consent Decree issued by the EPA (EPA, October 2000), are being implemented by the potential responsible party (PRP) and their consultants. HDR APTIM JV will be providing oversight of the PRP’s Response Action activities to ensure the PRP is working in accordance with EPA approved plans and is the focus of this DMP.

1.1 Site Background General Electric (GE), the PRP, used polychlorinated biphenyls (PCBs) at its 254-acre facility in Pittsfield from 1932 to 1977. During this time, the Transformer Division manufactured and repaired transformers containing dielectric fluids, some of which included PCBs. PCBs and other hazardous substances were released to soil, groundwater, Silver Lake, the Housatonic River and were disposed of within and around the facility in landfills, former river oxbows, and other locations. The Consent Decree (CD) for the Site was approved by the federal court in October 2000. The CD, the legal agreement between EPA and GE, segregated the Site into 28 separate cleanups.

The status of the 28 cleanup locations is as follows:

• Twenty Removal Actions Outside the River (also referred to as Removal Action Areas or “RAAs”). Remediation is complete and post-removal site control activities (e.g., inspection and maintenance activities) are ongoing at all RAAs.

o Ten in the GE Plant Area;

o Five in the Former Oxbow Areas;

o Three in the Floodplains;

o Silver Lake Area; and

o Allendale School.

• Five Groundwater Management Areas (GMAs): Long term monitoring is complete at two GMAs (GMA 2 and GMA 5), however GE is required to maintain certain wells and to conduct additional monitoring in these two GMAs at five year intervals Monitoring and response actions are underway at the remaining three (GMA 1, GMA 3, and On-Plant Consolidation Area (OPCA)/GMA 4).

• Three River Reaches:

o Upper ½-Mile Reach: Remediation is complete (Certificate of Completions was issued by EPA on February 4th, 2021) and post-removal site control activities (e.g., inspection and maintenance) are ongoing.

o 1½-Mile Reach: Remediation is complete and post-removal site control activities (e.g., inspection and maintenance) are ongoing.

1



o Rest of River (ROR): For the ROR, investigations under the CD have been underway since 1998. EPA issued its proposed remedial action in 2016 in the form of a RCRA Permit Modification. The Permit was appealed by five parties. A portion of the Permit was upheld and is in effect and other portions of the Permit are on hold. GE has agreed, pursuant to the 2020 Settlement Agreement to commence and perform investigations and design work as contractual obligations effective February 10, 2020. EPA issued a revised Permit for public comment in July 2020 and a Revised Final Permit in December 2020. The CD requires that after EPA issues its final remedy decision and all appeals have been satisfied, GE will implement the cleanup as a CERCLA remedy.

1.2 Field Investigation Description Based on current oversight responsibilities as described in the EPA-approved HDR APTIM JV Technical Approach dated November 18, 2020, HDR APTIM JV (HDR APTIM JV, November 2020), will perform oversight of PRP field activities and sample collection for the following:

• Surface water split sampling at the Silver Lake Outfall and the Pomeroy Avenue Bridge for PCB Aroclors and Congeners;

• Air sampling at the On-Plant Consolidation Area (OPCA)/Allendale School for PCB Aroclors;

• Surface water, soil and sediment split sampling associated with PRP ROR activities for PCB Aroclors and Congeners (surface water only)

HDR APTIM JV will oversee PRP response action field activities as determined is necessary by EPA. The primary goal of PRP oversight is to ensure that the data collected by the PRP is sufficient for the response action that will protect public health and the environment. HDR APTIM JV will meet these objectives by observing and documenting that the PRP has complied with all applicable laws, regulations, and requirements, and has met all performance standards specified in the EPA-approved Work Plan. Furthermore, GE’s data will be compared to EPA split sample results to determine if there may be issues with the quality of GE’s data and PCB concentrations in air at the Allendale School playground will be measured and compared to site-specific action levels and national guidance.

2 Purpose This DMP is site-specific and addresses the data management practices for the GE-Pittsfield/Housatonic River Site. Data will be collected by the PRP and HDR APTIM JV. This DMP addresses all aspects of data planning, collection, management, quality control, analysis, and presentation for this Site.

The primary required data types will be analytical results from surface water, soil, and sediment split samples, and air samples collected during the response action activities for the Site. Input on where to collect split samples will be provided by the EPA Remedial Project Managers (RPM). In general, the parent sample will be collected by the PRP and split sample provided to HDR APTIM JV. HDR APTIM JV will also collect air samples to support EPA’s sampling program. The number and location of split samples proposed is documented in the technical approach and is listed on the following page. Split samples will be collected and analyzed for PCB Aroclors and/or Congeners. Duplicate and matrix spike/matrix spike duplicate (MS/MSD) samples will be provided for laboratory quality control of PCBs.

2



(Note: MS/MSDs are not required for Congeners). In addition, equipment blank samples will be provided for air samples only.

HDR APTIM JV will provide the personnel to collect environmental split samples. HDR APTIM JV will document sampling and observational field data. HDR APTIM JV will collect, handle, and transport samples in accordance with the approved site-specific Uniform Federal Policy for Quality Assurance Project Plans (UFP-QAPP) (HDR APTIM JV, January 2021). HDR APTIM JV will arrange for the shipment and analysis of splits provided by the PRPs EPA-approved field activities as described below:

• Surface water split sampling for PCB Aroclors and Congeners: o Collect quarterly split samples with GE at two locations (11 events January 2021

through September 2023): the Silver Lake outfall and the Pomeroy Avenue Bridge.

o Collect two split samples as part of Rest of River (ROR) activities.

• OPCA/Allendale School Air sampling for PCB Aroclors: o Collect three samples plus one duplicate and one equipment blank sample (for a total

of five Poly-urethane Foam (PUF) samples per round). Sampling rounds will be conducted in July and September each year, starting in July 2021 for a total of six rounds.

• Soil and Sediment Split Samples for PCB Aroclors: o Collect soil/sediment split samples with GE for activities in ROR

• The number and type of samples collected may be modified to meet changing project needs, such as collecting split samples for the ROR Baseline Monitoring Plan or other ROR characterization activities.

3 Roles/Responsibilities The project-specific core data management team consists of the following roles and staff (see Contacts Table at the beginning of the document):

3.1 Project Manager The primary decision maker responsible for determining remedial activities and clarifying information necessary to successfully manage the site.

3.2 Data Manager The person responsible for implementing the data management sequence, in conjunction with the project manager, as detailed in Section 4.

3.3 Data Collection Personnel The team members responsible for collecting field data including sampling, monitoring and field analytical data.

Data Management Sequence Throughout the data management planning and implementation, HDR APTIM JV will request and perform analytical services in compliance with EPA requirements as outlined in our approved technical approach. In general, HDR APTIM JV will follow the Field and Analytical Services Teaming and Advisory Committee (FASTAC) tiered hierarchy for obtaining analytical services.

• Tier 1 – Office of Environmental Measurement and Evaluation (OEME) laboratory (includes Environmental Services Assistance Team (ESAT) support)

• Tier 2 – Contract Laboratory Program (CLP) Routine Analytical Services (RAS), CLP Modified Analysis, or National Non-RAS contracts

• Tier 3 – Regional OEME analytical contract mechanisms

• Tier 4 - Regional Field Sampling Contractor subcontracted laboratory services

5



To maintain continuity with how analytical services have been provided for the project in the past, Tier 4 analytical services will be provided via a subcontract to Eurofins TestAmerica. HDR APTIM JV will submit a Tier 4 request for approval for each sampling event. The request will be submitted to the EPA RPM to coordinate the appropriate approvals.

4.1 Data Planning Participants - Project Manager, Data Manager and Data Validator The data planning phase is the first step in properly collecting, managing, analyzing and presenting data throughout the life of the project. The data planning phase consists of:

• Review the project’s scope of work to determine the data necessary to complete the project.

• Prepare a Quality Assurance/Quality Control Plan describing the practices and procedures necessary to collect, analyze and interpret defensible data meeting the project objectives. A site-specific UFP-QAPP has been prepared and submitted to the USEPA for review and approval.

• Determine the data comparison criteria. PCB results from air samples collected at Allendale School will be compared to the action level of 0.05 ug/m3. Results from soil, surface water and sediment samples will not be compared to criteria; rather they will be used as a qualitative check on GE data.

• Develop a consistent data nomenclature. Sample names will be descriptive, follow a uniform pattern, account for the possibility of additional sample collection at a future time, and consider pre-existing sample nomenclature. See SOP-SM-03 – Sample Naming in the approved site-specific UFP-QAPP for specific guidance on sample nomenclature.

• Determine the required laboratory reporting format. The laboratory reporting format will follow the requirements listed in the approved site-specific UFP-QAPP.

• Determine the required electronic data deliverables format. The EDD format(s) used for the project will be selected based on database compatibility and the reporting laboratory capability.

• Confirm that the reporting detection limit for the chemicals of concern (COC) provided by the laboratory is appropriate for the project. The subcontract laboratory Eurofins/TestAmerica is able to achieve the reporting detection limits as specified in the QAPP.

• Determine the required data validation level, as applicable. Data Validation activities include evaluating and qualifying laboratory analytical data against predefined requirements outlined in the site specific UFP-QAPP. HDR APTIM JV will perform Tier II data validation of PCB Aroclors in accordance with EPA National and Regional Guidance documents. EPA will perform Tier II data validation of PCB Congeners. Upon completion of the data validation, HDR APTIM JV will upload the data and update the Data Management System

• Identify the data storage location. Data storage will follow HDR APTIM JV’s corporate policy regarding Information Lifecycle Governance. See the Data Management Summary table for storage information on other types of project related data.

• Identify staff who will require access to ProjectWise directories. ProjectWise is project collaboration software from Bentley Systems that allows project teams to manage, share and review project content in a single platform. Following HDR APTIM JV’s corporate policy

6



regarding Information Lifecycle Governance, the electronic folder management tool provides the capability to apply and manage permissions on project folders. Only users who require access to project directories will be given access.

• Identify the database for storing the analytical data. The EarthSoft EQuIS data management system will be used to manage the analytical data for the site. See section 5 of this DMP for additional information.

• Identify the project deliverables for the analytical data. The data management planning process for the project will include a discussion of what the project deliverables will be and what data is needed to complete the deliverables. Deliverables will include submittals after each sampling event, consisting of full data packages, validation reports, sample summary tables and trip reports (see technical approach for additional details). Also, split sampling data tables will be generated to compare GE results to EPA results to determine if there may be issues with the quality of GE's data. Split Sampling data summary tables will be generated and exchanged with GE for including in GE’s Reports and Documents. Finished products will utilize HDR APTIM JV standard formatting and templates (where applicable). All finished products will undergo QC review and be accompanied by a QC review form.

• Identify the database for storing the geospatial data. All spatial data for the site will be maintained using an ESRI file geodatabase. See section 5 of this DMP for additional information.

• Identify the project deliverables for the spatial data. After receipt of the spatial data from the incumbent contractor, HDR APTIM JV will convert the files to GIS feature classes and format them for compliance with the legacy applications used to present the data cartographically. HDR APTIM JV will use ArcGIS and other graphics support capabilities to generate approximately 50 figures that plot data with GIS information and 25 other figures generated with the ESRI file geodatabase or from commercially available information, such as Google Earth.

4.2 Data Collection Participants – Project Manager, Data Manager, Data Collection Personnel Data generated during the collection phase includes, but is not limited to, visual and olfactory observations and photographs. Procedures for collecting split samples for laboratory analyses and the types of analyses to be conducted during the removal action are provided in the site-specific UFP-QAPP.

The data collection phase will consist of the following:

• Search for and obtain existing data from other sources including the following:

o GE Monthly Reports - GE will provide data submissions quarterly basis or following any major sampling event to HDR APTIM JV. These submissions will be posted to SharePoint site set up by EPA and designated specifically for DB exchanges and available for download.

o Weston Access database - The data from the Weston Access database will be migrated into the EQuIS database format (Microsoft SQL Server based) for ease of use and accessibility. Data will be exported from the Weston Access database using queries into a format that matches an EQuIS EDD format. The exported data will be loaded to the EQuIS database. All of the data from the Weston Access database will be available and accessible from the EQuIS database when needed. The original Weston Access database will be archived and stored.

o Weston Geospatial data - The incumbent contractor provided their spatial data and GIS files to HDR APTIM JV. The files will be reviewed and catalogued for their potential use in future deliverables. The spatial data will be converted to GIS feature classes and incorporated into an ESRI file geodatabase where appropriate. The original GIS files and data will be archived and stored

• Obtain new data from the removal action oversight activities including the following:

o Surface water split sampling for PCB Aroclors and Congeners: Collect quarterly split samples with GE at two locations (11 events January

2021 through September 2023): the Silver Lake outfall and the Pomeroy Avenue Bridge.

Collect two split samples as part of Rest of River.

9





o OPCA/Allendale School Air sampling for PCB Aroclors and Congeners: Collect three samples plus one duplicate and one equipment blank sample (for

a total of five Poly-urethane Foam (PUF) samples per round). Sampling rounds will be conducted in July and September each year, starting in July 2021 for a total of six rounds.

o Soil and Sediment Split Samples for PCB Aroclors and Congeners: Collect soil/sediment split samples with GE for activities in ROR

Samples will be analyzed by the Eurofins/TestAmerica and results will be reported in EDD format which will be loaded to the EQuIS database.

• Document field activities, specifically recording measurements, observations, preparation of chains of custody (COCs) in the field, using either electronic means, or traditional hard copy. A trip report will be completed after each round of sampling. A Field Log will be maintained with detailed observations at the Site, including interactions with all parties, results of field tests, observations about conformance with the task order-specific plans and deviations from the approved plans. Field notebooks/journals and logs may be supplemented by photographs and/or videotaping and will include:

o Time, date, location, and weather conditions

o Visual characterization/description of site conditions

o Listing of all on-site personnel (full name, title, and affiliation)

o Tasks where oversight is being conducted

o A complete description of all activities

o Sample collection procedures and sample description

o Sample IDs, locations, and depths

o Descriptions of any issues or problems, and field deviations from the approved PDI work plan and protocols (including the HASP and QAPP). Any corrective actions/rectification measures that are planned or implemented will also be recorded.

The following documents will be prepared and submitted to the USEPA documenting the field activities:

• After each sampling round, a trip report will be prepared and will consist of a short summary of significant field events during the period, photographs taken during the period, and a copy of all field logs.

• Secure transfer and storage of field documentation. Daily field documentation including a copy of the field logbook and photographs will be promptly saved on a server or device backed-up daily at the direction of the Project Manager. At a minimum, field documentation should be photographed with a cell phone each day and saved under a project directory with a link sent to the project manager as a backup if loss of hard copies/field books occurs.

• Review and correction of COC information after receipt and log-in of samples at the laboratory the following day

4.3 Data Verification Participants - Project Manager, Data Manager, Data Collection Personnel, Data Validator, GIS Lead The data verification phase consists of:

• Respond to questions from the laboratory regarding sample issues during laboratory analysis

• Review of preliminary laboratory data for completeness and adherence to scope. Examples include making certain all the requested analyses were performed using the correct laboratory methods, all samples on the COC are accounted for, and the laboratory did not create sample nomenclature errors (i.e., typos)

• Request the laboratory run contingency samples/analyses

• Provide the data validator with the QAPP in advance of validation

• Review the final laboratory report and EDD formats for adherence to scope

• Production of field notes and photographic logs of field documentation shortly after demobilization by Data Collection Personnel. This is particularly important while still fresh in the minds of the field staff.

5 Data Management Systems 5.1 Analytical Data Management 5.1.1 EQuIS HDR uses the EarthSoft EQuIS environmental data management system to manage and store all of its environmental data. The EQuIS system is comprised of the EQuIS Data Processor and EQuIS Professional. More information can be found at: www.earthsoft.com

5.1.2 Access Microsoft Access may also be used either independently or in conjunction with EQuIS to store environmental data.

5.2 Spatial Data Management HDR APTIM JV uses ESRI’s ArcMap or ArcGIS Pro to spatially display its environmental data. Geospatial data will be saved to a geodatabase. More information can be found at: https://www.esri.com/en-us/home.
