• 15 October 2000 <br /> AGE-NC Project No 96-0232 <br /> Page 8 of I I <br /> ,water pump and treat system is initiated, AGE anticipates local ground water flow direction to be <br /> directed towards the areas of ground water extraction The proposed ground water extraction and <br /> treatment system is designed to prevent migration of hydrocarbons off-site, especially that of MTBE, <br /> to implement hydraulic control and to remediate petroleum hydrocarbon-impact to.ground water to <br /> regulatory satisfaction <br /> 26 Anticipated Length Of Time <br /> Pump-and-treat systems are effective in areas of shallow ground water impacted by MTBE Based <br /> on AGE's experience with ground water pump and treat systems and with existing site conditions, <br /> AGE anticipates a clean-up period between 24 and 36 months <br /> 3.0. RECEIVING WATER <br /> In accordance with Section C of Attachment A from General Order 5-00-119, AGE has evaluated <br /> the below-mentioned receiving water characteristics <br /> • 3 1 Description Of The Receiving Waters <br /> The Flag City Chevron ground water source removal extraction system will discharge treated ground <br /> water into the lateral canal owned by Mr Raymond Caldoni This drain line has a seasonal flow, <br /> with higher flow during the irrigation season (April to September) and almost no flow during the <br /> `off season' (October to May) <br /> This drain line intersects with the western leg of the Upland Canal in Section 14, Township 3 North, <br /> Range 5 East of the Terminous Quadrangle (USGS) <br /> The flow on the western Upland Canal is highly variable, dependent on surface drainage of both <br /> agricultural and surface water discharge from storm water The Upland Canal drains south into the <br /> White Slough Several other discharges from municipal and other service districts drain into western <br /> and eastern portions,of the Upland Canal and eventually into the White Slough <br /> The beneficial use of the water within the White Slough include supporting the floral and fauna <br /> habitat, and recreational usage The Woodbridge Irrigation District supplies water to the agricultural <br /> land in the area <br /> The water discharge from the Flag City Chevron will not degrade the ambient.water quality of <br /> Upland Canal The quality of the water discharge will be within the discharge requirements of the <br /> Advanced GeoEnwronmentul,Inc <br /> t <br /> y <br />
