Hall; dginter@dbsr.com; Cori Condon; Dan Watts Subject: Replacement RIW Location On September 10, 2001, 1 spoke with Toni Guantone of Delta College regarding where the College has decided it wants to locate the new irrigation well. The College wants to locate the well at Site 1, as identified in the Siegfried Engineering, Inc. report titled 'Preliminary Engineering Report, San Joaquin Delta Community College, Irrigation Water Well,Alternate Well Sites,"dated August 22, 2001 (the"Report"). Site 1 is located in Parking Lot Holt 1, approximately 1,700 feet from the former RIW abandoned in August 2001. See Figure 2 of the Report for the location of Site 1. The College is going to physically mark (paint an "V)on the asphalt surface, sometime this week, where the replacement well is to be located. Once the well is marked, a survey will be completed by the College to confirm that the well is not located within 50 feet of sanitary or storm sewer lines. This location is reportedly very close to existing electrical service and water conveyance system (see the Report). The UST Cleanup Fund responded to the Report on September 6, 2001, and confirmed their prior correspondence that$175,000 was a reasonable cost to complete the replacement well, and that"the Fund will not pay for a new pump, control panel, pressure tank, special design and construction oversight costs or any costs in excess of$175,000 associated with installation of the well at a distant location." Further, the Fund stated that"it will not be responsible for the cost of replacement irrigation water after December 31, 2001." Since the SECOR report concluded that the replacement well could be located within close proximity (25 to 50 feet)of the abandoned RIW, as long as specified construction standards were followed, e.g.,260 feet of conductor casing, and the Fund, RWQCB and San Joaquin County PHS-EHD concurred that this was acceptable during the last conference call, there should be no objections (based on contamination issues)to relocating the well to Site 1. The College should be prepared to address at the next conference call the costs in excess of$175,000, if any, associated with a new well at Site 1. Steve (714)632-8521, ext. 224 9/11/01
