F <br /> y � , <br /> 7� <br /> Karen Petryna <br /> Equiva Services,LLC <br /> Page 5 <br /> Action item: Sam Savig to send letter to Shell. <br /> 1071 N Main Street <br /> The last report submitted recommends no further site assessment but continued quarterly <br /> groundwater monitoring. Sam Savig and Dot Lofstrom gave preliminary agreement to this <br /> conclusion, with the statement that they will need to verify that the horizontal and vertical extent <br /> of contamination has been defined. <br /> Action item: Sam Savig to provide verbal agreement with recommendations. If there are <br /> additional concerns, a letter stating the concerns will be provided to Equiva. <br /> 341 Main Street <br /> The extent of contamination may not be completely delineated at this site. However,the <br /> concentration of MtBE has been substantially reduced in the monitoring wells at the site. Ms. <br /> Petryna said that Equiva would like to shut the groundwater extraction system down for two <br /> quarters, and then monitor for two additional quarters to see if there is a rebound. The County <br /> agrees with this approach and that the system will be shutdown immediately following the next <br /> quarterly monitoring event. Also, an earlier SVE study indicates that SVE is not a valid.remedial <br /> action for this site. That report is missing from the County's files. <br /> Action item: Cambria to submit SVE report. <br /> If you have any corrections,comments, or questions regarding this meeting summary,please call <br /> Dot Lofstrom at(209) 468-3436 <br /> Donna Heran,REHS,Director <br /> Environmental Health Division <br /> —04/Ii,- <br /> Dot Lofstrom,RG <br /> .
