I have accepted this <br /> reference and description as the work plan procedures to be followed for the MIP test. <br /> "Standard operation procedures are included in LFR's 'Work Plan for <br /> Environmental Investigation' dated September 26, 1996. The aforementioned <br /> work plan includes procedures for direct-push (i.e. CPT) drilling. A <br /> description of the MIP technology is given below. A final work plan will be <br /> submitted after the MIP technology is proven to be 'effective' . <br /> MIP Technology Description <br /> The Membrane Interface Probe(MIP) is advanced using a standard string of <br /> 1.25" or 1.5" rods and a direct push probing unit. Before advancing the <br /> probe, the tubing which houses the carrier gas and conductivity cable is <br /> connected to the MIP tool and is strung through the probe rod. The rods are <br /> then loaded on a rod cart or fixed tool rack for easy dispensing and <br /> storage. As the probe is driven to depth, the advancement is stopped at <br /> desired intervals (typically six inches) to gather VOC data. Conductivity <br /> logging data is gathered on a continuous basis. At the desired intervals, - <br /> the permeable membrane interface on the wall of the probe is heated. Any <br /> VOCs that are exposed to the membrane are volatized and picked up by the <br /> carrier gas behind the membrane which in turn delivers the gas the Gas - <br /> Chromatograph detectors at the surface, typically and ECD, PID and/or FID. A <br /> stringpot, which is mounted on the probe, senses movement of the probe and <br /> measures depth and speed. The data is stored in spreadsheet compatible <br /> format for later graphing and analysis. The Gas Chromatograph readings <br /> provide total VOC readings and are stored as well for plotting.

I've been in touch with the Andy of LFR and he's getting me a map <br /> and some info on the grouting. <br /> has there been a work plan submitted to you for this phase? <br /> -----Original Message----- <br /> From: Marie McCrink [mailto:MTMcCrink@waterboards.ca.gov] <br /> Sent: Tuesday, November 08, 2005 4:49 PM <br /> To: Mike Infurna [EH] <br /> Cc: Don.Bradshaw@lfr.com; Lucas.Goldstein@lfr.com <br /> Subject: Approval for CPT / MIP Work at Lincoln Center Stockton <br /> Hi Mr. Infurna, <br /> 1 <br />
