Composite samples will be collected from the proposed disposal site and <br /> analyzed for copper, chromium, and arsenic to establish background levels. <br /> As long as levels of these constituents in the drilling mud are not <br /> significantly higher than background disposal can proceed. If levels are <br /> significantly higher (but still below hazardous levels) , leaching tests <br /> will be required to determine if the proposed disposal method is still <br /> acceptable. <br /> 2. If the drilling muds have not been completely dried and disced into the <br /> soil before the start of the rainy season (approximately mid-November) , the <br /> berms must be heightened to provide at least a two-foot freeboard. <br /> If you have any questions, please call Gary Reents at (916) 361-5742. <br /> V <br /> ANTONIA K.
