Stantec Colting Corporation �RECEI RECEIVED i / 3017 Kilgore Road Suite 100 Rancho Cordova CA 95670 Tei:(916)861-0400 DEC 0 2 2010 Fax: (916)861-0430 RantecENVIRONMENTAL HEALTH PERMIT/SERVICES November 17, 2010 File: 185702199.200.0001 Mr. Harlin Knoll San Joaquin Environmental Health Department 600 East Main Street Stockton, California 95202 Reference: Well Permit Application Packet Former Time Oil Terminal Port of Stockton Stockton, California Dear Mr. Knoll: On behalf of TOC Holdings Company (TOC), Stantec Consulting Corporation (Stantec) submits this permit application packet for the destruction of 15 wells and the installation of four replacement monitoring wells at the above referenced site (Figure 1). A work plan was submitted to the California Regional Water Quality Control Board (RWQCB) on November 15, 2010. Stantec is currently waiting for RWQCB approval of the work plan. Attached is a well permit application for the destruction of wells TONT-1 through TO/T-5, TONT-8, TONT-11, TONT-12, TONT-14, and TO/R-1 through TO/R-6 and the installation of replacement monitoring wells TONT-2R, TO/T-3R, TO/R-2R, and TO/R-5R (Table 1). All of the wells proposed for destruction have a total depth of 10 feet bgs. Also included is a check for well permit fees ($2,684). We understand that the normal method of well destruction allowed by the county is overdrilling. However, one of the wells (TO/T-12) located on the terminal is inaccessible to a drill rig due to its location between above ground pipelines. We request that a variance be issued for the destruction of this well to allow for the well to be pressure grouted instead of overdrilled. Additionally, wells TONT-3, TONT-4, and TONT-11 are located behind terminal infrastructure. We are attempting to determine if any of the infrastructure can be removed to permit a limited access rig to access the wells, however, if this is not possible, we further request that these three wells be allowed to be pressure grouted. We would like to schedule field activities to begin immediately upon approval of the work plan by RWQCB. We'd like to see this field work begin during the month of November 2010, due to potential flooding or soft ground that can occur with continued rainfall, which may make some wells inaccessible.
