TO 0009 Environmental Cleanup Plan
Section 1 - Introduction
The objective of this project is to address the soil contamination at Area of Concern (AOC) 55 located at Camp Stanley Storage Activity (CSSA), Boerne, Texas. This Environmental Cleanup Plan describes the interim corrective measures and the environmental studies and investigations to be performed.
Parsons intends to achieve these objectives by executing a removal action of contaminated media from areas surrounding the suspected landfill area(s). A surface geophysical study will be implemented to identify lateral extents of the area of concern and slit trenches dug to attempt to characterize the landfill. Following completion of the removal action, Parsons will install a low water crossing to replace the existing bridge structure which will be removed as part of the removal action at AOC 55.
The scope of work as detailed in the task order authorizing this project includes:
|
Preparation of project and/or site specific addenda to the planning documents to be incorporated into CSSA’s Environmental Encyclopedia. |
|
|
Development of a Quality Program Plan, which consists of a project-specific addendum to the Health and Safety Plan (CDRL A001), a project-specific addendum to the Sampling and Analysis Plan (CDRL A002), and an Environmental Construction Quality Plan to conduct site construction activities (CDRL A003). |
|
|
Development of and Environmental Cleanup Plan that will include, as appropriate, of the following subsections. (CDRL A005) |
Site Security Plan
Excavation Plan
Spill and Discharge Control Plan
Surface Water Management Plan
Erosion Control Plan
Remediation Management Plan
Siting Analysis Plan
Site Preparation Plan
Demobilization and Closure Plan
Standard Operating Procedures for Hazardous Waste (CDRL A007)
Explosive Safety Plan (CDRL A011)
|
Providing support for the environmental management and geographical information systems; all data will be collected and recorded in a format compatible with CSSA’s GIS. |
|
|
Submitting all analytical data, including quality control results and cross-reference tables. Raw data, case narratives, AFCEE forms, data verification, data validation summary reports, a copy of approved project variances, and a listing of the project data quality objectives will also be provided. |
|
|
Preparing photo documentation of field activities and sample locations. |
|
|
Submittal of deliverables to AFCEE and the submittal of individual ERPIMS data files (e.g., analytical results, groundwater level data, etc.). |
The overall data quality goal for this project is to gather sufficient information to guide the selection of remedial alternatives and interim corrective measures and to obtain “clean” closure for the site. Data quality is defined by its representativeness, precision, comparability, and completeness. Representativeness of the data is dependent on site selection and the number of samples taken, which will be addressed in the sampling plan design. The requirements for precision, comparability, and completeness of the data vary between data types but all are enhanced by the use of standardized sampling and analysis protocols and standardized reporting procedures. DQOs are dynamic documents that are continually being updated as the project progresses and data is generated. The most current DQOs are presented in Appendix A. Detailed information on sampling techniques are given in the Draft AOC 55 Sampling and Analysis Plan Addendum, Parsons, January 2003.
The type(s) of data to be collected for this project are listed below, along with a discussion of their uses and requirements.
|
Geophysical data – An electromagnetic induction (EMI) ground conductivity survey will be conducted to identify subsurface features that might influence groundwater and contaminant movement. Data will be validated or “ground-truthed” by exploratory trenches planned for the AOC 55 area. |
1.4 - Electronic Data Management
Field data collected during the course of the project will be stored and submitted to CSSA in electronic format. The purpose of the electronic data management program is to provide a comprehensive method through which field information and data can be stored, reviewed, and managed. The electronic files will be incorporated into a database specifically designed to manage anticipated field data collected on a daily basis. The electronic files will be generated by scanning field logbooks, inputting field measurements into an electronic field notebook, and recording data with dataloggers or geophysical equipment. All field personnel involved in data collection activities will be required to undergo training in the electronic field data management techniques that will be used under this delivery order.
Field logbooks will be used to record daily field activities and field observations. Daily entries into the logbook may include work hours, field personnel, weather information, sampling times, and observations. Logbook entries will be handwritten using permanent ink. A new page will be started each day of field activities and entries will continue onto successive pages as necessary. At the end of each day, the field team leader will sign the field logbook and unused portions of the last page will be marked through to prevent further entries.
At the end of each field day, the team leader will electronically scan that day’s entry into the field logbook. The pages will be scanned to create a graphic format electronic file (JPEG or similar) using the electronic scanner in the CSSA environmental office. The hard copy of the field notes will be stored in Parsons field and project files.
1.4.2 - Dataloggers/Geophysical Instrumentation
Management of data collected by specific instrumentation with datalogging capabilities, such as from the weather station datalogger and geophysical equipment, will be stored within the internal memory of the instrument until it can be downloaded to a computer. Electronic file formats for the downloaded data will be determined by the format generated with each instrument. Data will be downloaded into the database at the end of each day, at the end of a profile for geophysical surveys requiring multiple days, or at pre-established intervals for longer measurement events.
1.4.3 - CHERP Database Application
The CHERP’s database application is currently designed to generate COCs and labels for collection of samples submitted for laboratory analyses. The database ensures that all required information for delivery of ERPIMS data is entered. The field screening data collected on a daily basis will be incorporated with the daily logs to provide efficient and expedient review of data. The electronic database application is set up to allow synchronization between networks at CSSA and Parsons. This will allow review and observations of daily field activities by CSSA and Parsons Managers.
