P.O. Box 2009 Stockton, California 95202 May 10, 1993 Union Ice Company 1320 Weber Street Stockton Soil Remediation Dear Mary, This letter and the attached site map constitutes our pian to aerate soils at the Union Ice Plant at 1320 Weber Street. As you know we have excavated approximately 6000 cubic yards of soil from the former fuel tank area at the site. Those soils are stockpiled on the site to the East of the excavated area. You are also aware that the backfill material used to re-fill the excavation was taken from the area East of the cold storage building. We are in the process of leveling that area and we will then spread the excavated material in the excavated backfill area. Once we have spread the soil we will have to go in and remove the debris that is mixed with the excavated soils by hand. When this is done we will be aerating the soil with a disc, or with a rototiller attachment on a tractor. The soil contamination levels are well below the 50 ppm limit that the air resources board plces as the level requiring a permit to aerate.We have enclosed copies of the analytical data for your perusal. We have asked the air resources people at your request to send you a letter or call you to let you know that they have no permit requirements for this project. Samples will be taken from each lift of soils that are aerated and we are asking that we be required to take samples at the rate of one sample per 50 cubic yards of soil aerated, rather than your normal requirement of one sample per 25 cubic yards. We will be sampling for TPF gasoline and diesel/kerosene as well asthe 601 compounds using mthe appropriate Luft or EPA methods. Please let us know if you require any additional information. We will be starting the spreading process on Monday May 17,1993 unless you have an objection to that date. Thank you for your interest in the project.
