<br /> A ABLE 'I -CHECKLIST OFREQUIRED DATA
<br /> FOR NO FURTHER ACTION REQUESTS AT UNDERGROUND TANK SITES
<br /> i
<br /> Site Name and Location: Former Flame Liquors,Inc., 1301 W.Kettle man Ln.,Lodi, San Joaquin County(RB#391017)
<br /> Yd1. Distance to production wells for municipal, domestic, A 2011 sensitive receptor survey identified three water
<br /> agriculture, industry and other uses within 2000 feet of the site. supply wells within the 2,000'search area, one 470'to the
<br /> est one 650'to the south, and one 1,000'to the north of
<br /> the Site. None of the wells are threatened by the release.
<br /> Y 2. Site maps, to scale, of area impacted showing locations of In June 1998, three 10,000-gallon gasoline USTs and
<br /> any former and existing tank systems, excavation contours and a ssociated piping were removed.

<br /> By: J Comments:In June 1998, three 10,000-gallon gasoli a USTs and associated piping were removed from the
<br /> subject Site.Based upon 41 quarters of groundwate r monitoring showing a stable plume with a slowly
<br /> Date: declining concentration trend, the limited extent of ontamination remaining in soil and groundwater, no
<br /> 10/4/2011 foreseeable changes in land use,and limited threats from groundwater,soil, and soil vapor intrusion,
