I <br />1 <br />11 <br />I <br />I <br />I� <br />Section 2 <br />SITE DESCRIPTION <br />The McMullin Gas Dehydrator Station is located in San Joaquin County, approximately 2 miles south of <br />Manteca and %, mile south of the intersection of Airport Way and Perrin Road. The station is owned by <br />PG&E and occupies an area of approximately one-third acre which is relatively flat and covered with <br />gravel fill. The adjacent land to the north, south, east and west of the dehydrator station are used for <br />agricultural faruiland and for raising cattle. <br />The facility is unmanned and has been used for odorizing and removing production fluids in the natural gas <br />since 1961. During the 1960's, a glycol reboiler and production fluids tank were located in the northeast <br />and northwest comers of the site, respectively, and the dehydrator tower was located near the center of the <br />site (Figure 2). The glycol reboiler included a still for condensing the production fluid vapors which <br />drained to a nearby sump. <br />The site was reconstructed some time after 1973 and the layout of the major process equipment has <br />remained the same since that time. As a result of the reconstruction activities, the glycol reboiler unit was <br />moved to the center of the site and the production fluids tank was replaced with a larger capacity tank <br />surrounded by a concrete basin (Figure 3). All production fluids generated from the reboiler unit are piped <br />to the above -ground production fluids tank for storage. <br />The McMullin Gas Dehydrator Station lies at an elevation of approximately 25 feet above mean sea level <br />in the San Joaquin Valley. The San Joaquin River, located approximately 2000 feet to the west of the site, <br />is the nearest surface water body (Figure 1). <br />cca08/19/93(9660a.doc/cp43) 2-1 <br />
