_ 2 42115195 Listed below are the key items of concern by EHD and their recommended course of action and compliance date(s): 1. EHD questions Weston's analytical testing capabilities; regulatory guidelines for detection limits are not always incorporated in Weston reports. EHD feels the district might be better served by using an independent lab for analytical testing and reporting. Currently, Weston uses their own lab to test ,for constituents in samples prepared by a Weston investigation.! 2., EHD requests that all analytical data resulting -from activities at the Lodi yard, from 19BB to date, be compiled and submitted to them for their review immediately. 3. EHD requests that a corrective action plan for soil contamination at the Lodi yard be.prepared and submitted by April 15, 1995. 3 4.- EHD requests that groundwater monitoring and sampling for the three (3) monitoring wells at the Stockton yard be initiated by March 31, 1995. 5. 'EHD requests'that all analytical data resulting from activities at the Stockton yard, from 1987 to date, be compiled and submitted to them for their review immediately. 6. EHD requests that a corrective action plan for soil contamination at the Stockton yard be prepared and submitted by May 15, 1995. Most of the work requested needs to be performed by outside professionals or consultants. I am prepared to help facilitate the compilation of records and data from the Lodi and Stockton yards from records retained by the district. 'The datatinformation collected may have to be developed into a formal report prior to submission to EHD, which could be performed by outside consultants. The development of corrective action plans for the Lodi and Stockton yards would have to be created by outside consultants. Water monitoring and testing would also have to be performed by outside consultants and laboratories. After evaluating the above listed items, and my discussions with EHD, Weston, and the California Regional Water Quality Control Board, I feel that we should take appropriate action to accommodate all of the requests made by EHD at this time. Additionally, there are several actions we can take to facilitate the cleanup of the two sites and reduce our liability with the existing UST's. Y "
