Minutes - San Leandro City Council Meeting - April 6, 1992 Page - 17 - PUBLIC HEARINGS (continued) Council Member Santos noted there had been numerous tests over the years and asked what was the potential for contamination based upon past testing. Mr. McManus said it was difficult to conclude ahead of time what the outcome would be; but he said, based on review of data to date, only a small amount of tarry material around the old oil tank area had been found and had been cleared up. He said the rest of the data indicates that typical clean-up mitigation and remediation can be done. Council Member Santos noted that no Federal or State agencies had issued any citations, etc. , on the site. Mr. McManus said that was true and that the matter had only been reopened because regulations have changed over the years. Council Member Glaze asked how they decided where to do sampling. Mr. McManus said they focused on the areas with the highest possibility of finding contamination, particularly in the area of the Trojan Powder Company activities, as well as areas that were not tested before and areas that were distributed according to an aerial photograph throughout the site. He said testing would be on-going up until groundbreaking but that all information needed for investigation will be known. He described the various phases, such as soil tests, water samples, etc. He said the PEA would identify impacts and determine mitigation and remediation, and this would become part of the project activities. In response to a question from the City Council , he said fill brought to the site will only be tested if it is suspected to contain contaminants. Council Member Perry asked how they knew what was in the groundwater and if it was normal for a PEA not to be done at this time. Mr. McManus said they would be installing groundwater monitoring wells and conducting surface testing depending upon the results of the investigation. He said it is typical that the PEA is not completed this early in the entitlement process, and the Department of Toxic Substances prefers that it not be done too early because the situation and site could change. Mr. McManus said the PEA should be completed prior to approval of the Precise Development Plan. Mayor Karp noted that the developer cannot even build until the State declares that the site is clean. Council Member Santos asked if groundwater contamination transcends borders and if there had been any evidence that groundwater in the surrounding area had been contaminated. Mr. McManus said no, there was no evidence that the underlying native soils or bay mud, which is fairly impermeable, have been contaminated.
