The Fourth QMR provides a summary of <br /> activities conducted during 2003. The Report discusses the destruction of monitoring well <br /> MW-1, the installation of four monitoring wells, and the soil and grab groundwater sampling <br /> results from four borings, four conepenetrometer borings, and the four newly installed <br /> monitoring wells. Based on the results of analytical data collected from the site, the Report <br /> includes a site conceptual model (SCM) that concludes that the pollution at the site is from the <br /> underground storage tanks (USTs) removed in 1991 instead of the aboveground tanks (AGTs) <br /> that are actively used at the site. The Report recommends the installation of additional deep <br /> monitoring wells in the levee area around the former USTs. <br /> We have the following comments on these reports: <br /> 1. The practical quantitation limit (PQL) for the fuel oxygenates does not meet the <br /> requirements of Monitoring and Reporting Program (MRP)No. 5-01-835. H&H Marina <br /> must meet the PQL before a fuel oxygenate can be removed from the sampling schedule. <br /> 2. Regional Board staff concur that a small portion of the pollution currently observed at the <br /> site may be the result of a discharge from the former USTs. However, the following is a <br /> list of technical issues that the SCM does not adequately explain how the pollution is <br /> solely from the USTs: <br /> California Environmental Protection Agency <br /> Co Recycled Paper <br />
