The following participants were in <br /> attendance: <br /> Kyle Christie ARCO Products Company Ron Zurlinden Brown and Caldwell <br /> Jay R. Johnson EMCON Margaret Lagorio PHS/EHD <br /> Mary Meays PHSIEHD Linda Turkatte PHS/EHD <br /> Diane M. Hinson PHS/EHD Michael Infurna PHS/EHD <br /> The following are summaries of the discussions and agreements reached for each site. <br /> 1711 E. Yosemite, Manteca ARCO Facility #6020 <br /> PHSIEHD contact - Michael Infurna <br /> A update of the status of the tanks at this site will be submitted to PHS/EHD in order to <br /> determine a future plan of action for the nominal soil contamination found at the site. Because <br /> groundwater in not impacted, this site has a lower priority status at this time and will be <br /> monitored and sampled yearly. <br /> 7906 N. EI Dorado St., Stockton: ARCO Facility #2130 <br /> PHSIEHD contact - Michael Infurna <br /> The remedial system is currently operating. The two new air sparge wells were installed but <br /> only two air sparge wells can be operated at a time. The destruction efficiency of the system <br /> is below 95% but the emissions are still in compliance with air standards. <br /> The integrity of the well heads of monitoring wells MW#3 and MW#4 was discussed and will be <br /> followed up by EMCON. It was decided that the upgradient well MW#8 will be destroyed as it <br /> is a hazard to vehicles and to samplers and because sufficient data showing the approximate <br /> extent of the groundwater plume at the site has already been collected. A workplan for this <br /> destruction, a permit application and the associated fee of $60.00 must be submitted to <br /> PHSIEHD. <br /> 441 W. Charter Way, Stockton ARCO Facility #2168 <br /> PHSIEHD contact - Michael Infurna <br /> The station is no longer in operation and the tanks are to be removed soon. An executive <br /> summary for the proposed over-excavation of impacted soils at the site has been submitted <br /> and the site will enter public participation soon. <br /> A joint meeting of all responsible parties identified for contamination in the area was held on <br /> A Division of San Joaquin County Health Care Services <br />
