ASTM E1819-15 (R2021) pdf free download.Standard Guide for Environmental Monitoring Plans for Decommissioning of Nuclear Facilities.
1.1 This guide covers the development or assessment of environmental monitoring plans for decommissioning nuclear facilities. This guide addresses: (1) development of an environ mental baseline prior to commencement of decommissioning activities; (2) determination of release paths from site activities and their associated exposure pathways in the environment; and (3) selection ol appropriate sampling locations and media to ensure that all exposure pathways in the environment are monitored appropriately. This guide also addresses the interfaces between the environmental fliOflitoring plan and other planning documents for site decommissioning, such as radiation protection, site characterization, and waste management plans, and federal. slate, and local environmental protection laws and guidance. This guide is applicable up to the point of completing D&D activities and the reuse of the facility or area for other purposes.
4. Summary of Guide
4.1 Nuclear facilities must have established plans for monitoring the environment surrounding the site as part of their license or technical specifications. These plans are designed to identify any release of radioactive or hazardous material and to assess the resulting impacts. Similar plans are required during surveillance and maintenance, decommissioning or site rernediation to continue environmental monitoring, although the types of discharges and the affected pathways may he different from those monitored during facility operations.
4.2 In addition, limited environmental surveillance may have been performed since the facility operated. The existing environmental monitoring plans should be modified for decommissioning and reflect the current environment, potential release points, and affected pathways. if flO environmental monitoring plan exists, OflC must he developed.
4.3 The decommissioning environmental monitoring plan must be consistent and complete to ensure the detection and mitigation of oil-site impacts caused by radioactive or hazardous materials released from decommissioning activities at nuclear facilities.
5. Significance and Use
5.1 Use of this guide will ensure that the potential impact on the surrounding environment from planned decommissioning activities has been properly assessed.
5.2 Use of this guide will ensure that the adequacy of environmental sampling has been assessed for location, frequency, analytical techniques. and media type to monitor the environment and to detect site-related releases and their impact.
6. Organizational Interfaces
6.1 The environmental monitoring plan should coordinate with other decommissioning documents. Guide El 281 recommends that certain planning documents and implementation plans will be prepared prior to commencement of dismantlement actions. This guide ensures that the basic environmental monitoring planning elements and requirements are identified. examined, and addressed to accomplish the decommissioning activities. Other project plans and reports guide the operations and organization for the decommissioning project.
6.1.1 Planning and implementation documents define the activities around which the site environmental monitoring program will he developed. Documents that should he reviewed include the following.ASTM E1819 pdf download.
