General Provisions and Scope

The criteria in 105 CMR 120.244 apply to the decommissioning of facilities licensed under 105 CMR 120.100,120.300, 120.500, 120.800 and 120.900. (A) The criteria in 105 CMR 120.244 does not apply to sites, which have been decommissioned prior to October 6, 2006. (B) After a site has been decommissioned and the license terminated in accordance with the criteria in 105 CMR 120.244, the Agency will require additional cleanup only if, based on new information, it determines that the criteria of 105 CMR 120.244 were not met and residual radioactivity remaining at the site could result in significant threat to public health and safety. (C) When calculating TEDE to the average member of the critical group the licensee shall determine the peak annual TEDE dose expected within the first 1000 years after decommissioning. (D) Specific time limits for completion of the decommissioning process are as specified in 105 CMR 120.132(G). (1) Licensees shall complete decommissioning of the site or separate building or outdoor area as soon as practicable but not later than 24 months following the initiation of decommissioning. (2) When decommissioning involves the entire site, the licensee shall request license termination as soon as practicable but not later than 24 months following the initiation of decommissioning. (E) The Agency may approve a request for an alternative schedule for completion of the decommissioning of the site or separate building or outdoor area, and license termination is appropriate, if the Agency determines that the alternative is warranted.
