The Letter is a follow up to the conversation we had on <br /> 16 March 2005 regarding reconsideration of Regional Board staffs request for sampling near the pipeline. <br /> The Letter provides the following reasons to reconsider the request for additional work: <br /> • The 8 December 2003 Field Investigation Report and Request far a Comfort Letter(Report) <br /> submitted by Treadwell&Rollo on behalf of Mr.Tom Brenkwitz,property owner of 541 West Grant <br /> Line Road in Tracy states that the pipeline should not be considered a source of pollution.. <br /> • There is no evidence of the presence of jet fuel in the area. <br /> • Pipeline integrity records show no records of documented leaks in the vicinity of the area of concern. <br /> • Data provided in the Report suggests a historic release with no ongoing leaks or spills. <br /> • Any additional sampling would need to be 20 to 30 feet from the active pipeline,which have already <br /> been collected. <br /> The Letter states, "Chevron would welcome the opportunity to sample,via a neutral party,an existing <br /> well near the pipeline, using the proper protocol to identify jet fuel." Regional Board staff concurs with <br /> this suggestion. By 24 May 2005,please submit a work plan discussing the sampling protocol, location, <br /> neutral party,method for identifying the jet fuel, and a schedule to perform this work.
