1 The existing IEMP TLD monitoring network will be modified in late 2002 to take into account
2 the pending relocation of the wastes stored in the K-65 silos. As necessary, current TLD
3 locations will be adjusted and new TLD locations added to adequately characterize and monitor
4 the direct radiation in the vicinity of the AWR project and the site fenceline. The following
5 new TLD locations are planned for the Silos area:
6 0 Location 43 located on the western side of the Silos, near the KNW-A radon monitor,
7 0 Location 44 located on the western side of the Silos, near the KSW-A radon monitor.
8 Location 45 located on the southern side of the Silos, near the KSO radon monitor
9 0 Location 46 located on the project boundary south on the transfer tank area building
10 0 Location 47 located on the project boundary south of the planned location of the Silos 1
11 and 2 remediation facility

The silo area dirpct radiation monitoring locations (TLDs) are shown in Attachment A. Due to
project construction activities, it may be necessary to re-locate TLDs. Changes in monitoring
locations will be documented and approved through the DCN process
16 3.3 Wastewater Monitoring
17 All wastewater from the Silo 3 Project, AWR Project, and Silos 1 and 2 Project will be
I 8 discharged to the FEMP Advanced Wastewater Treatment ( A M ) facility, after sampling to
19 confirm that it is acceptable for transfer. Expected wastewater streams from Silos Project
20 activities will be appropriately incorporated into the FEMP NPDES permit. Given the expected
21 characteristics of the wastewater, and the discharge criteria for the AWWT, no wastewater
22 unacceptable for transfer to the AWWT is expected to be generated. If analytical results for
23 a particular batch of wastewater are found to be unacceptable, the batch will be managed on
24 a case-by-case basis at the direction of AWWT operations. The specific disposition of the
25 wastewater will be dependant upon factors including the amount, and specific characteristics
26 of the batch of wastewater and upon current and planned AWWT operations at the time the
27 AWR wastewater is generated. Details on the disposition of wastewater from each project

Groundwater monitoring is currently managed by the Aquifer Restoration Project (ARP). The
ARP provides the monitoring necessary to identify the effect of FEMP remediation activities.
This monitoring is adequate for assessing potential impacts on groundwater quality due to the
Silo 3 and AWR projects. In the event that collection of groundwater samples is needed to
support the projects (or to assess any incidental releases), ARP managers will be notified to
coordinate the appropriate groundwater monitoring activity.
