ATTACHMENT B:MAP OF WELLS/AREA OF REVIEW STIG-LEC facility is located on the eastern edge of the Delta and just to the west of 1-5. Other information on the physical setting of the area is included in the AFC and summarized here. The STIG-LEC facility is located in the City of Lodi, although the main part of the city is located 6 to 7 miles to the northeast. The land on which the STIG-LEC facility occurs is owned by the City of Lodi,as shown in Figure B-2, and is designated by the City of Lodi as Public/Quasi-Public. Most of the other land owned by the City of Lodi near the power plants,WPCF, and Vector Control facility are used for effluent irrigation and biosolids application. Nearly all other land within approximately 3 miles of the power plant sites are designated by the County as General Agriculture. The climate in the Lodi area is typical of the Central Valley. The climate,frequently described as Mediterranean,is characterized by warm to hot summers without rainfall. Precipitation in the Lodi area averages about 17 inches per year and occurs between December and April. Surface Water Features Numerous natural and developed surface water bodies occur near the STIG-LEC facility. To the west are numerous sloughs,cuts,and canals that deliver surface water to local farmers. The other local surface water features in the area are the percolation ponds at the WPCF,the breeding ponds for fish at the vector control facility,and White Slough.White Slough runs along the south side of the facility,and eventually flows north and drains into the Mokelumne River. Figure B-1 shows these local surface water features. Along the west side of the City of Lodi property (about 1,500 feet west of the STIG-LEC facility) are several elongate water bodies that roughly parallel I-5. These were initially borrow pits constructed in 1972 to provide material for the construction of I-5. They were originally intended to part of the initial section of the Peripheral Canal. They are now open water bodies. West Yost and Associates (2006)reports that they are not connected directly to the Delta,are recharged by precipitation,and interact with shallow groundwater. The White Slough Wildlife Area is located northwest of the STIG-LEC facility,and is operated and maintained by the California DFG. Other Local Features Two other features occur within the 1-mile radius of the STIG-LEC facility. The first is the high-level electrical transmission lines and the substation on the west side of the STIG facility. The second is four residences located on an unnamed road east of 1-5 between Thornton and Kingdon roads. Well Inventory Several types of wells occur within the AOR. These include: • Municipal and Industrial wells • Domestic wells • Irrigation wells B-2 SAG371322I082550015(ATTACHMENT-B.DOC)
