Mr. Mike Pitta - 3 - 19 December 2006 <br /> prepared at a minimum for TPH gasoline, TPH diesel, benzene, and MTBE in groundwater. <br /> Additionally, an estimate of the time for groundwater chemical concentrations to reach water <br /> quality objectives is required in future annual reports. <br /> The Regional Water Board conditionally concurred with MNA as an acceptable groundwater <br /> remediation strategy for the site by letter dated 25 March 2005. In response to the July 2006 <br /> fuel spill, KMEP implemented the contingency plan of recovering SPH from the surface and <br /> water table and removing soil containing SPH from the vadose zone. Residual groundwater <br /> petroleum hydrocarbon concentrations following remedial response activities were within the <br /> range of historical data for the site. Therefore, MNA with associated contingency measures in <br /> the event of a future release or if plume characteristics change remains as an acceptable <br /> remedial strategy. <br /> If you have any questions regarding this letter, you may contact me at (916) 464-4719 or <br /> mclardys'a�waterboards.ca.gov. <br /> Mark W.
