Kettleman Lane, Lodi, California (Site). The Report provided the analytical results of <br />one direct push soil boring (attached Figure 1) to 56.5 feet below ground surface, using a 20 -ton <br />Cone Penetrometer Testing rig near the former UST complex. Maximum soil results were Total <br />Petroleum Hydrocarbons as gasoline, 75 milligrams per kilogram (mg/kg), and Methyl tert Butyl <br />Ether, 0.001 mg/kg. The soil results, when compared to the San Francisco Bay Regional Board <br />Environmental Screening Levels, November 2007 (ESLs), did not exceed the ESLs. <br />On 14 April 2008, Regional Board staff rescinded quarterly monitoring pending the closure <br />review. Therefore, in order to proceed into the public participation phase for the closure: <br />You are to submit a property parcel map depicting your site, the extent of your identified <br />hydrocarbon plume, and all parcels located within 250 feet of your site and/or your <br />defined hydrocarbon plume. You are also to identify the location of City of Lodi Municipal <br />Well Number 12 on the property parcel map. For each parcel, located within 250 feet of <br />your site and your defined hydrocarbon plume, you are to provide the parcel number, the <br />name of the owner for each parcel, and a mailing address for each owner. <br />2. You are to submit a public notification document (Fact Sheet) for our review. The Fact <br />Sheet should contain a very brief site history, discussing investigative and remedial <br />activities conducted at the site, current site conditions, and your findings that the residual <br />constituents mass remaining in soil and groundwater beneath your site does not pose a <br />threat the human health or waters of the state. The Fact sheet must also state your <br />intent to obtain site closure from the Regional Board, and include a method by which any <br />interested individuals may obtain additional information regarding the site or make <br />comments regarding the possible closure of the site. I have informed your consultant, <br />Arcadis, of our requirements. <br />California Environmental Protection Agency <br />Ccl Recycled Paper <br />
