The GMR shows that groundwater beneath the site contained <br /> benzene, toluene, ethylbenzene and xylene (BTEX), total petroleum hydrocarbons (TPH) and the <br /> fuel additives methyl tertiary butyl ether(MTBE) and tertiary butyl alcohol (TBA). The highest <br /> detectable concentrations were found at N-15 which contained benzene at 2,400 µg/1 and TPH in <br /> the gasoline range at 8,500 µg/l. N-22 contained MTBE at 5.9 µg/1 and TBA at 390 µg/l. The <br /> NPDES MR contains the first quarter 2001 reporting as required by Waste Discharge <br /> Requirements Order No. 5-00-217 issued on 27 October 2000. <br /> The WP is acceptable so long as the following comments are incorporated into the work or <br /> adequately addressed prior to beginning work. <br /> 1. The WP proposes to accomplish source area characterization'in two phases. The WP <br /> provides for Phase I work and states, "if data from field-screening activities suggest that <br /> the data from the proposed locations in the Phase I area do not meet the objectives of this <br /> California Environmental Protection Agency <br /> �a Recycled Paper <br /> The energy challenge facing California is real.
