K--�� <br /> San Joaquin/ARCO Meeting Minutes, March 30, 1993 Working To Restore Nature <br /> o SJ stated that they do not have any records of failed tank tests or releases <br /> which would allow them to require site assessments at the adjacent properties. <br /> ARCO would have to initially assess in these areas to bring in other PRPs. <br /> o RESNA stated that authorization from Caltrans would be required to drill in <br /> Charter Way. City access could be obtained to drill in Lincoln Street. <br /> ARCO SS No. 6020, West Yosemite Ave., Manteca <br /> o RESNA informed SJ that a Preliminary Investigation and Evaluation Report <br /> has been prepared and will be submitted shortly following ARCO's review. <br /> RESNA summarized the results of the recent investigation, stating that <br /> hydrocarbons were not detected in the soil borings or ground-water samples <br /> collected from the newly installed monitoring wells. <br /> o SJ requested that the ground water be monitored for one full year. RESNA <br /> informed SJ that ground-water elevations are being monitored on a monthly <br /> basis to evaluate changes in the flow direction. Monthly monitoring will <br /> continue until a trend is established. <br /> o RESNA informed SJ that only minor amounts of hydrocarbons at low <br /> concentrations (3.5 ppm TPHg) have been identified in soil in the vicinity of <br /> the underground storage tanks. SJ stated that the soil affected by <br /> hydrocarbons near the USTs could likely be removed when the tanks are <br /> replaced in the future. <br /> o SJ and ARCO indicated that this site is of low priority. <br /> ARCO SS No. 760, South Cherokee Lane, Lodi <br /> o Linda Turkatte referenced the recently submitted work plan for an additional <br /> investigation involving the installation of three vapor-extraction wells. She <br /> also referenced a letter addressed to ARCO dated July 19, 1992, in which she <br /> requested that the ground-water be assessed beneath the site and listed areas <br /> of concern onsite which she felt warranted further investigation. SJ is <br /> requiring assessment of ground water beneath the site based on hydrocarbons <br /> detected at 36 and 46 feet below surface grade (bsg) and an historical ground- <br /> water elevation of 40 ft bsg. Areas of concern onsite included the area near <br /> the former tank cavity were borings B-5 and B-20 are located; Linda stating <br /> 5 <br />
