The station is owned by PG&E and occupies an ar=t of approximately one-third acre which is relatively flat and covered with gravel fill. The property surrounding the dehydrator station is used for agricultural farmland and for raising cattle. i Tle facility was constructed in 1961 for odorizing and removing production fluids from natural gas i collected from gas wells in the area. During the 1960s,a glycol reboiler and production fluids tank were located in the northeast and northwest comers of the site,respectively,and the dehydrator tower was located near the center of tf;c site. The glycol reboiler included a still for condensing the production fluid vapors which drained to a nearby sump. The site was reconstructed some time after 1973 and the layout of the major process equipment was changed. The glycol reboiler unit was moved to the canter of the site and the production fluids tank was replaced with a larger capacity tank surrounded by a concrete basin(Figure 3). All production fluids generated from the reboiler unit were piped to the above-ground production fluids tank for s'_orage. In 1996 the station was taken out of service and dismantled. All of the major process equipment has been removed from the site, and the site remains fenced and covered with gravel fill. The McMullin Gas Dehydrator Station lies at an elevation of approximately Z5 feet above mean sea level in the San Joaquin Valley. I'he Sart Joaquin River, located approximately 2000 feet to the west of the site, is the nearest surface water body(Figure I). f i . 402_331-9$ 63 2-1 I
