Weber Avenue, 3rd Floor <br /> Stockton, CA 95202-2708 <br /> SUBJECT: BORING PERMIT APPLICATION-375 WEST HAZELTON, STOCKTON, CA. <br /> To whom it may concern: <br /> ALTA EM, INC. has been retained to conduct a routine investigation for potential environmental <br /> issues at the subject site. This investigation is being conducted above and beyond an existing <br /> leaking UST case registered with your agency. The work is exploratory in nature, and is not <br /> based on any known or confirmed environmental issues on the site. The drilling is being <br /> completed to assess for possible petroleum hydrocarbons related to former on-site operations <br /> and UST issues on adjoining properties. <br /> The investigation will consist of drilling 6 or 7 soil borings to approximately 20 feet deep, and <br /> possibly collecting groundwater samples with a hydropunch in selected areas. Soil samples will <br /> be collected at approximate 5 foot depth intervals, and selected soil and/or water samples may <br /> be analyzed for petroleum hydrocarbons, BTEX, MTBE and other fuel oxygenates. Chemical <br /> analytical work would be completed by a State of California Department of Health Services <br /> certified laboratory. Analytical methods would include various combinations of EPA method nos. <br /> - 8015 modified, 8021b, and 8260b (limited to BTEX and fuel oxygenates). The drilling <br /> will be completed with either a push probe or hollow stem auger rig. <br /> Attached are the following: <br /> • A site sketch showing approximate exploratory drilling locations <br /> • A completed boring permit application <br /> • A completed Licensed Contractors Declaration form <br /> • A completed MFR form (by property owner) <br /> • Letter from property owner authorizing the drilling/permitting <br /> • Two checks for permit and inspection fees ($89 and $279) <br /> We were hoping to complete this work next Thurs/Friday (6/10 & 6/11) based on rig availability. <br /> Can the permits be processed by this time, or can the work proceed with a verbal approval of <br /> permits? We are located in Southern California and need to make travel arrangements. Please <br /> call me if you need any additional information (909) 476-2120. <br /> Very y Yo s, <br /> A A EM <br /> BERT B. HANSEN <br /> Project Env.
