1. Scope
1.1 This guide covers the development or assessment of environmental monitoring plans for decommissioning nuclear facilities. This guide addresses: (1) development of an envi- ronmental baseline prior to commencement of decommission- ing activities; (2) determination of release paths from site activities and their associated exposure pathways in the envi- ronment; and (3) selection of appropriate sampling locations and media to ensure that all exposure pathways in the envi- ronment are monitored appropriately. This guide also addresses the interfaces between the environmental monitoring plan and other planning documents for site decommissioning, such as radiation protection, site characterization, and waste manage- ment plans, and federal, state, and local environmental protec- tion 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. 1.2 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Terminology
3.1 Definitions: 3.1.1 active phase, n—time during which physical decontamination/dismantling operations are performed. 3.1.2 characterization, n—a systematic identification of the types, quantities, forms, and locations of contamination on the site. 3.1.3 Data Quality Objectives (DQOs), n—quantitative and qualitative statements that specify the quality of data needed from a particular data collection activity. 3.1.4 decommission, vt—to remove safely from service and reduce residual radioactivity to a level that permits release of the property for unrestricted use and termination of any applicable licenses. 3.1.5 decontamination, n—activities employed to reduce the levels of (radioactive or hazardous chemical) contamination in or on structures, equipment, materials, and personnel. Typical forms of decontamination may include: (1) decontamination to support decommissioning objectives; (2) decontamination to reduce radiation levels in support of as low as reasonably achievable (ALARA) objectives; (3) decontamination to limit the spread of radiological contamination; (4) decontamination to support the unrestricted release of material and equipment; and (5) decontamination of personnel. 3.1.6 monitoring, vt—observing or taking measurements systematically over time to determine the status ofand to detect significant changes in conditions or performance of a system, facility, or area. 3.1.7 passive phase, n—time of surveillance and mainte- nance from the time plant operations cease until decontamination/dismantling operations begin, and from the end of active decontamination/dismantling operations until the site is released for unrestricted use. 3.1.8 radiological release criteria, n—levels of residual radioactivity present at the completion of a decommissioning activity below which the site may be released to the general public for unrestricted use. 3.1.9 hazardous material clean-up criteria, n—the reduction of hazardous contaminants needed to reduce the risk identified in the baseline health-based risk assessment to a level consis- tent with Applicable and Relevant or Appropriate Requirement (ARAR) values. 3.1.10 hazardous substance, n—any material identified by the Environmental Protection Agency (EPA) in 40 CFR 262. 3.1.11 restricted use, n—organizational control is main- tained over a property through physical barricades, signs and notices, or deed covenants that limit the full use ofthe property by an owner or prospective owner. 3.1.12 unrestricted use, n—control over the property is fully released for any use desired by the owner.
4. Summary of Guide
4.1 Nuclear facilities must have established plans for moni- toring the environment surrounding the site as part of their license or technical specifications. These plans are designed to identify any release ofradioactive or hazardous material and to assess the resulting impacts. Similar plans are required during surveillance and maintenance, decommissioning or site reme- diation to continue environmental monitoring, although the types of discharges and the affected pathways may be 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 decom- missioning and reflect the current environment, potential re- lease points, and affected pathways. If no environmental monitoring plan exists, one must be developed. 4.3 The decommissioning environmental monitoring plan must be consistent and complete to ensure the detection and mitigation of off-site impacts caused by radioactive or hazard- ous materials released from decommissioning activities at nuclear facilities.
