Unauthorized Release Fact Sheet <br /> Moore Petroleum Bulk Plant <br /> 5491 T" Street, Banta, California <br /> Introduction <br /> This fact sheet has been prepared to inform surrounding community members about proposed"No <br /> Further Action"designation associated with unauthorized release and subsequent clean up associated with <br /> former underground storage tanks(USTs)which leaked at the Moore Petroleum Bulk Plant located at <br /> 5491 "F"Street,Banta, California. <br /> Site History <br /> The Moore Petroleum Bulk Plant is currently a card lock refueling station with two aboveground storage <br /> tanks(ASTs). In 1998, seven 10,000-gallon and two 350-gallon USTs were removed from the site. The <br /> over-excavated soil was transported to Forward Landfill in Manteca,California for disposal. Soil and <br /> groundwater investigations have been performed from 1998 through 2012 in order to define the aerial <br /> extant of the contamination around the site. The extent of contamination in soil and groundwater has been <br /> defined by the investigations through the installation of groundwater monitoring wells both on and off <br /> site. <br /> Remediation Cleanup <br /> From 1995 to 1997, an internal combustion engine was used onsite to remove soil vapor from the <br /> subsurface. In 2002,a soil vapor extraction(SVE) system began removal of gasoline related <br /> hydrocarbons from the subsurface. The SVE system was supplemented in 2006 with the addition of <br /> ozone sparging through 10 ozone sparging points. Both systems operated onsite until 2009. Over the <br /> course of remediation associated with this site,vapor extraction has removed over 6,000 pounds of <br /> gasoline related constituents from the soil and groundwater. <br /> Subsurface Investigations <br /> The site has been characterized by 15 groundwater monitoring wells, 3 groundwater monitoring/soil vapor <br /> extraction wells, 2 soil vapor extraction wells, 1 recovery well, 1 domestic well, 10 ozone sparging wells, <br /> and 18 soil vapor survey points. Soil investigations have been conducted from surface to approximately <br /> 80 feet below ground surface. Groundwater monitoring has been conducted onsite since 1992. Two soil <br /> vapor surveys were conducted onsite in 2007 and 2011. <br /> If you have any questions about the information provided above please contact: <br /> Victoria L McCartney,REHS <br /> Joaquin County <br /> � waeS by 2015c,San Joa <br /> q ty 5ve%jyr 7g02 �-tau <br /> Environmental Health Department �2 <br /> Telephone: (209)468-9852 0z---: �Ij 7 <br /> Email: vmccartneY0-s6cehd.com <br />
