Lower Colorado Water SUDDlv Proiect (LCWSP)

Status of the Lower Colorado River Water Supply Project

Work is continuing on the Lower Colorado Water Supply Project (Project). As a
consent item, I have included in the Board folder the sixth submittal of applications for
Project water. I am requesting that the Board recommend to Reclamation, with the
approval of Resolution 2004-2, that the following applicanls are eligible to receive
Project water and the City of Needles should offer a subcontract 10 each applicant.

For this sixth submittal, there are four applications requesting water. These four
new applications are for newly subdivided parcels. The original land had been previously
approved for a total of 4 acre-feet of Project water per year (CRB Document No. 366),
i.e., one acre-foot for the current use and three acre-feet for future uses. After
subdivision, the original landowner occupies the same residential house as her principal
residence and had sold one subdivided parcel and keeps the remaining two parcels. A list
of the number of the four parcels and the water requested is shown below:

progress in perchlorate remediation efforts at Las Vegas Wash. Also, it was reported that
Kerr-McGee's new treatmenl system. Fluidized Bed Reactor (FBR), began operations in
the start up mode in April of 2004. Since April, Kerr-McGee has been trying to optimize
the perfonnance of the FBR treatment system by increasing the flow ofthc system to full
operational status. The flow to FBR is about 1,000 gallons-per-minute (gpm) and the
perchlorate concentration to the FBR system is approximately 250 ppm. The effiuent
concentration has varied between non-detect to 20 ppb. The variation in the effiuent
