The initial preliminary site appraisal showed no evidence of overt <br /> soil contamination, excessive waste storage nor improper disposal <br /> activity. Good 'Housekeeping' and Work Area Planning show training <br /> and concern by COZAD personnel. <br /> 2• The removal of the underground tanks became a matter of consternation <br /> initially because there was not-an Environmental Assessor to explain <br /> the analytical results and liaison with the regulatory agency. The <br /> initial laboratory was of no help by reporting units in parts per <br /> billion rather than parts per million; This at first glance, called <br /> for some extreme remediation activities. In reality, and in sum, <br /> LESS THAN TEN CUBIC YARDS OF SOIL WAS CONTAMINATED AND AT NO TIME <br /> DID IT EXCEED 200 mg/kg. All indications point to a possible tank <br /> overfill at sometime and not a leaking UFT. <br /> 3. The three underground tanks have been removed and disposed according <br /> to TriValley Water Quality and Department of Health Service mandates. <br /> The comparatively minimal contaminated soil was aerated according to <br /> Article 8 of the State Air Quality Board's ''.RULE 40. <br /> The soil was sampled, analyzed [EPA SW846j and reviewed by California <br /> Department of Health Certified Laboratory.-.-.In'shoirt; the soil is <br /> as 'clean' as can be expected and can be relocated anywhere on the <br /> property. <br /> This note concludes a preliminary site appraisal, assessment, and <br /> UFT remediation operation.
