However, a Quarterly <br />Report was not submitted. <br />A meeting was held June 26, 1991 between Ultramar, Applied Geosystems, PHS/EHD, and the Central Valley <br />Regional Water Quality Control Board. It was agreed that quarterly monitoring should commence. The <br />September 27, 1991 PHS/EHD letter requested that a Quarterly Report be submitted by November 14, 1991. <br />No Quarterly Report has been submitted to date. <br />Not only has groundwater been contaminated, but the extent of this contamination has not been defined. <br />The groundwater gradient, when last measured (1987), was to the southwest. Therefore there is not a down <br />gradient well which would delineate the contamination boundary. Additional soil and groundwater <br />investigation will be required. <br />Submit by January 31, 1992 a Quarterly Report and workplan to further assess the groundwater <br />contamination of this site. If the Quarterly Report is not submitted by January 31, 1992 formal enforcement <br />action may be requested. <br />If you have any questions or you wish to schedule a groundwater sampling inspection please contact <br />Mary Meays, EHS, of my staff at (209) 468-3441. <br />Jogi KhannaD., M.P.H. <br />He�allthhQfffifi';rl�` <br />kaurie A.
