Technical Approach Provided by Project Manager:
The technical approach to the preliminary evaluations and investigations will consist of sampling soil, surface water, and groundwater to determine the nature, extent, and mobility of the contaminants associated with the waste units. Once the sampling has been completed, analysis of the data will be performed to evaluate the current and future impacts to human health and the environment due to the waste unit. This information will be used to screen remediation technologies to identify the most effective remedy. The remedy will then be implemented, and post-action monitoring initiated to ensure that it is effective.
The types of remedies that are anticipated to be used or are currently in use on the Lower Three Runs and Operations Project are capping (using either natural or synthetic materials), removal and proper disposal of contaminated soil and sediments, and other actions resulting from the FFA process.
In addition to these standard technologies, the Environmental Restoration Division is aggressively pursuing innovative technologies that will either enhance the effectiveness of the remedy or minimize the cost. Innovative technologies to be deployed in this project are SCAPS logistics, CPT well installation, and well-head analyzer methods as alternate sample collection and well installation technologies that eliminate or significantly reduce aqueous or non-aqueous Investigative Derived Waste (IDW). A long term closure cover system for humid climates and additional alternate sample collection and well installation technologies that eliminate or significantly reduce aqueous or non-aqueous Investigative Derived Waste (IDW) are technology needs that have been identified for this project.
Once ER's waste sites have been closed (remediated) in accordance with regulatory requirements and are in post closure phase, the sites will require regular maintenance such as erosion control, placement of signs, fence repair etc. Periodic inspections and monitoring is also required. Also required is verification that the generated waste meets the acceptance criteria of the designated treatment, storage and disposal facility.
Activities include:
• Performing programmatic initiatives and process improvements for technical activities such as technology development, risk assessment, codes & standards, training, software research, safety documentation, and configuration management.
• Centralized coordination of waste certification / pollution prevention / waste minimization within the ER department.
• Systematic evaluation of waste areas to lead to a defensible recommendation for either conducting further response action or taking no further action through a graded, step approach.
• Conduct well monitoring and analysis through groundwater sampling, analysis, data management, well maintenance, and reporting.
Post 2006 Project Scope Provided by Project Manager:
P-Area Reactor Seepage Basins (904-061G, 062G, 063G) remedial activities will be completed by FY 2007. Stormwater Outfall P-010 will complete remedial activities by FY 2008. R-Area Burning/Rubble Pits (131-R, -1R) remediation activities will be completed by FY 2010. Par Pond Sludge Land Application Site characterization, assessment, and remediation construction activities will be completed by FY 2013. R-Area Rubble Pile (631-25G) activities will be completed by FY 2015. Post-closure activities such as maintenance and monitoring will continue.
Project End State Provided by Project Manager:
The Lower Three Runs Watershed Project will meet the EM site end state after the completion of the remediation and monitoring described in the technical approach. After remediation has been completed the sites will be subject to periodic 5-year reviews of the Records of Decision, and the portions of the project where institutional controls were implemented to continue to require oversight until the property is transferred with appropriate deed restrictions.
