As requested in the Water Board's November 5, <br /> 2010 letter to Shell, an NFA report was submitted on January 6, 2011. Due to the <br /> continued absence of petroleum constituents in groundwater, Shell is requesting <br /> permission to discontinue monitoring and sampling while the NFA is being reviewed. <br /> 050222(12) 2 CONESTOGA-ROVERS&ASSOCIATES <br />
