`ftw 'tiff May 4,2004 NOA ENVIRONMENTAL PROJECT NUMBER E04029A 5.0 CONCLUSIONS AND RECOMMENDATIONS The piles of stakes and wire from the former vineyard should be removed from the subject ,. property. The pile of debris to the east of the property should be periodically monitored for indiscriminate disposal of potentially hazardous materials. If the two above-ground diesel tanks are to remain in use,they should be placed within secondary containment to minimize the potential for leakage. If the tanks are not to remain in use, they should be removed from the site and disposed in accordance with all applicable laws and —' regulations. A formal request should be placed with PG&E to definitively identify which transformers can be considered PCB-contaminated. Any such transformers should either be replaced or periodically monitored for leaks. NOA recommends that the three transformers from 1960 be replaced if they are indeed those observed at the former residential area. 6.0 LIMITATIONS This report was compiled as a Surface/Subsurface Contamination Report for the subject project. This report contains information and data provided to NOA by several sources. NOA in no way warrants the accuracy or completeness of the information provided to this investigation by those sources. It should be noted that when a surface/subsurface assessment is completed without sample collection and quantitative analysis of soil and groundwater beneath the site, as in this study, no statement of scientific certainty can be made regarding latent subsurface conditions which may be the result of on-site or off-site sources. The findings and conclusions of this report are not scientific certainties, but rather, probabilities based on professional judgement concerning the significance of the data gathered during the course of this investigation. NOA is not able to represent that the site or adjoining land contains no hazardous waste, oil, underground storage tanks, or other latent condition beyond that detected or observed by NOA during the Surface/Subsurface assessment. The possibility always exists for contaminants to migrate through surface water, air, or groundwater. Our office has not been provided with specific criteria for the development of this report other than a request to evaluate the property in question for possible problems related to toxic or hazardous agents,nor have we been directed to address any specific questions concerning the site. Should there be a need to conduct an investigation into a specific question not addressed in this report, contact our office immediately regarding your concerns. 13
