0 0 <br /> surface. Comment: This seems to be wording related to a soil vapor sampling point since it states <br /> that the sampling point will be advanced to depths of approximately 5 feet bsg or within the base of <br /> the buried waste. The wording suggests a single soil vapor sampling point is planned as opposed to <br /> what is typically constructed (e.g., a LFG well screened at depths corresponding to waste and <br /> collecting a sample representative of the screened interval of the well). <br /> A set of two soil-vapor samples will be collected from the soil-vapor points and analyzed for <br /> volatile organic compounds by TO-15 and Fixed Gas Analysis by ASTM method 1946. Initially, <br /> a duplicate soil-vapor sample set will be collected from the soil-vapor point to evaluate the <br /> results and provide a comparator. Comment: what is meant by"a set of two soil vapor samples?" <br /> (Earlier the work plan said sampling at 5 feet bgs or base of wastes.)What is a "comparator?" <br /> t+ LEA edf <br /> SO <br /> The email from AGE stated that they prepared a "work plan scope" for the "soil-vapor sampling <br /> and analysis" at the solid waste area at 500 East Louise Avenue. It stated that AGE will prepare a <br /> soil boring —well permit for the proposed soil vapor probe today for finalization and requested that <br /> the LEA please review and let AGE know what additional information the LEA will need to get this <br /> well installed and sampled.A response approximately one hour later that same day stated that the <br /> LEA did not request or direct this [scope of work] and that they thought it was premature. <br /> Comments: Typically if a LFG investigation is planned to be conducted, the planned activities are <br /> presented in a work plan that is submitted to the LEA for review and comment prior to conducting <br /> the planned activities. <br /> 01 1001 <br /> C� + <atds RN€11 t to the <br /> The email from Reynolds & Brown stated that as a follow up to a call on Friday, attached please <br /> find the CIWMB's [CalRecyle] SWIS form indicating that the site was closed in 1986. The email <br /> stated that as discussed, they had performed significant investigative work at the direction of the <br /> SJCEHD's LEA and CalRecycle has asked us to complete additional work and that also as <br /> discussed, it was the goal of Reynolds & Brown "to recycle this land and make it available for <br /> industrial development." It was stated that it was desirous to try to coordinate this work so as to <br /> manage our resources as best we can, come up with a plan that works for everyone and avoid <br /> duplicative work if possible. The email stated availability the week before July 4 at the Water <br /> Boards convenience to visit the facility and, in addition to discussing "recycling the former closed <br /> landfill area," discuss the plan for actively remediating the diesel spill issue. <br /> Ninyo&Moore 1 500 E.Louise Avenue,Lathrop,San Joaquin County,California 1 104690095 1 August 11,2017 34 <br />
