Mr. Robert Silverstein, Esq. 0 Review Of The Recirculated DEIR And FEIR For The San Lorenzo Sewer Lift Station Project January 12, 2012 Page 2 of 18 What the RDEIR does not say is that the 1989 project included totally new mechanical and electrical equipment. There is not a single piece of mechanical or electrical equipment from the 1960s pump station that is still in use. The 1989 plans for the rehabilitation of the Bristol Pump Station (as it was then called) and the Maxine Pump Station were prepared by the engineering firm CWC -HDR, Inc. Drawing 6 of 10 shows that the original 1960s pump station had its pumps in the 8 -foot diameter concrete structure and that all of the mechanical and electrical equipment from the 1960s project was removed in the 1989 project. See Exhibits A and B. The 8 -foot diameter pump station structure became the wet well for the 1989 project and is the only part of the 1960s facility that is still in use. None of the maintenance reports that I have been provided mention any problems with this structure. The wet well structure is essentially a large manhole. Usually manholes have an effective life of one hundred years or more. The FOR refers again in comment J -6 on Page FEIR -60 to the "age of the equipment" implying that the equipment is very old. This is factually incorrect, The real truth is that the existing pump station is a 1989 pump station, not a 1960s pump station. Furthermore, the two pumps were completely rebuilt in 2007. See the attached invoice from the Orange County Pump Company. (Exhibit C.) The invoice reads, "Disassemble and assess all pump and motor components. Remove and replace the following parts ". The listed parts include the seals and bearings, i.e. the parts that are likely to wear out. There is a handwritten note on the invoice saying, "Work Completed 2- 1 -07 ", The pumps that were installed in 1989 were rebuilt in 2007, 18 years later. The complete re -build of the pumps should have brought them back to near new condition, thus they should last for at least approximately another 18 years, i.e. until the year 2025. The RDEIR asserts in Paragraph 2,2 on Page 2-6 and elsewhere that, "...it is difficult to obtain necessary replacement parts for the existing equipment," and uses this as another justification for the Project. This assertion is repeated in comment J-6 on Page FEIR -60. 55A -151
