RE: LTPFollow Up Flag: Follow upFlag Status: FlaggedJohn,With respect to the draft questions associated with the topic of Development of Embedded and Buried Piping DCGLValue, the following clarifying information is provided.Please let me know if any additional information is required.Regards,JimThe cover material depth for buried piping is 2 meters. The TBD will be revised to reflect the 2meter depth.The 9.67E-04 mrem/yr in the TBD is correct. The new RESRAD runs were performed after the RAIresponse was submitted.Section 5.4.3.2 will be revised in Revision 2 of the LTP to include the two paragraphs with theexception of the GARDIAN Ill. The GARDIAN III was not available therefore we will be using theGARDIAN. The second paragraph will be revised to describe the four vs six detector configuration.The TBD we will submit will evaluate the use of the GARDIAN system.We will also add to the end of the 2nd paragraph: "Either bulk assay method must be able toadequately assess soils to the same rigor of a MARSSIM FSS. As such, materials surveyed via liftsor bulk survey methods will be subject to the same NRC review, inspection and confirmatorysurveys associated with all site FSS survey areas."From: Hickman, John [1]Sent: Thursday, February 26, 2015 6:03 AMTo: Morris, James R
