The Hanford LTS Program is described in the Hanford LTS Program Plan and includes two distinct elements:
- Transition process is a disciplined process that is used to ensure all transition steps have been taken, that the post-cleanup requirements have been fully identified, and that the corresponding LTS information has been transitioned from the cleanup projects contractor to the Hanford LTS Program contractor (MSA).
- Execution Activities – Various activities such as on-site or in-the-field monitoring, assessments and inspections, etc. are required to maintain the known as-left condition of remediated areas such as waste sites and interim safe storage reactors turned over to the LTS Program. Monitoring may include radiological monitoring and other types of monitoring per applicable resource management plans.
- Transition checklist is used by the cleanup organization and the Hanford LTS Program to ensure all preliminary activities have been completed and that the associated documentation of those activities is in place in the form of a Transition and Turnover Package (TTP).
- Transition and Turnover Package (TTP): Contain the information needed to transition the geographic area from the cleanup program to the LTS Program, including as-left facilities and infrastructure, surveillance and maintenance requirements for the area, cleanup that was completed and active real estate agreements in the area. TTPs are reviewed and approved by both the cleanup program and the associated cleanup contractor.
- Contract Transition: used to transfer contractual responsibilities from the cleanup contractors to the LTS Program contractor. These documents are necessary documentation for seamless contractual transition to occur from cleanup projects contractor to the Hanford LTS Program contractor with DOE-RL approval. Each TTP document goes through several review cycles to ensure it provides the technical documentation of what was cleaned up and what may have been left behind.
- Information Management during Transition: provide TTP processing support, establish initial processes and procedures, records management,
Institutional Control (IC) Assessment/Repair
S&M requirements are outlined in the interim/final ROD for a given geographic area decision. LTS maintains a Sitewide S&M plan that identifies the various activities that are performed to meet the ROD requirements. The S&M plan aligns with DOE/RL 2001-41 Sitewide Institutional Control Plan, which defines the specific ICs necessary to manage the physical remedies installed to protect human health and the environment. Based on the S&M plan, LTS provides surveillance, inspection, and reporting on remedies and ICs to verify continued conformance with regulatory requirements, primarily the RODs.
MSA LTS provides annual assessments of all MSA-owned WIDS sites (per the MSC Contract, Table J-14) under the environmental protection process documented in an internal procedure MSC-PRO-15334, Rev. 2, Effluent and Environmental Monitoring. The inspections are completed to document any physical or administrative changes to the sites.
Radiological monitoring will be performed at waste sites and structures to evaluate changed conditions as they are identified through planned Surveillance and Maintenance activities. Monitoring is based on requirements including Title 10 Code of Federal Regulations (CFR) Part 835, “Occupational Radiation Protection”;
Remediated waste sites have requirements to maintain a vegetation cover. Closure requirements for a site specify the species component of revegetation and a schedule for monitoring and reporting the status. Until final closure requirements have been met, the schedule of monitoring and reporting must be met. Additionally, species and cover requirements must be maintained. Disturbed sites invite invasion of undesirable or noxious weeds. Weeds will need to be controlled to promote desirable vegetation.
The Hanford Site contains significant resources (e.g., endangered, protected, listed species) that are managed under various laws, orders, and treaties. Specifically, resources are managed and protected through resource management plans (RMP) and area management plans (AMP) within the framework of DOE/EIS-0222-F, Final Hanford Comprehensive Land Use Plan Environmental Impact Statements. Resources having RMPs include the following
Safe Storage Enclosure Surveillance & Maintenance Activities
Currently six of the nine production reactors have been placed in interim safe storage (i.e., cocooned). The cocooned reactors are referred to as Safe Storage Enclosures or SSEs. The Surveillance and Maintenance (S&M) plans listed below require annual external surveillance and internal surveillance every five years. The Surveillance and Maintenance Plans for each reactor can be found using the following links:
Internal surveillance for 105-C, 105-D, 105-H, 105-F, and 105-N/109-N SSEs was conducted in fiscal year 2015. A report of the surveillance & maintenance activities may be found at the following link
Internal surveillance for the 105-DR SSE was conducted in fiscal year 2016. A report of the surveillance & maintenance activities may be found at the following link:
Based on results of the FY15 and FY16 interior inspections of the 6 SSEs and the housekeeping/repair actions taken in 2016, TPA agencies agreed to change the inspection period from a 5-year interval to a 10-year interval. The TPA change notices (TPA-CN-0711, TPA-CN-0712, TPA-CN-0713, TPA-CN-0714, TPA-CN-0715, TPA-CN-0716) can be found in the Administrative Record.
In the unlikely case that extreme natural events, vandalism, or unanticipated events result in a need for corrective actions, the LTS Program will respond. The response may include modifying processes, such as making adjustments to the type and frequency of monitoring and maintenance activities, modifying existing controls, establishing new controls, and if directed by DOE, initiating new cleanup actions.
CERCLA 5-Year Review
For waste sites where contamination that prohibits unrestricted use remains, CERCLA requires a review no less frequently than once every 5 years to evaluate the implementation and performance of a remedy to determine if the remedy is or will be protective of human health and the environment. The 5-year review requirement applies to all remedial actions selected under CERCLA §121.
Transfer out of DOE Ownership
The DOE/RL LTS program ends with the conveyance (transfer) of property to another federal or nonfederal agency. This could include one large transfer of all lands at one time or multiple transfers of smaller land parcels over a period of time.
Information Management During Execution
Information management tasks include:
- Operational surveillance and maintenance data and record generation activities
- Providing data management and records management support,
- Ensuring configuration controls and other management controls are in place and used to protect and preserve the records and data, and manage the long-term system needs of the LTS Program.
- Defining requirements, information management supporting business processes, and required systems in support of the Long Term Stewardship (LTS) program.
- Capturing other currently unidentified LTS data sets, support systems and applications containing LTS data, and methods for capturing and storing the data under MSA’s control.
