After an EPA required 90 -day <br />reclassification period, an oil sample was taken to find the final PCB classification. The oil spill around the transformer <br />and surrounding pad was cleared and de- contaminated. The oil that reached the ground around the pad was removed and <br />replaced with new soil. <br />Secor also did a pre - demolition survey of the existing office building for asbestos and lead -based paint (LBP) and found <br />evidence of asbestos materials and isolated areas that were historically painted with LBP. Mitigation Measures regarding <br />asbestos removal have previously been included in the Air Quality Section of this Initial Study to reduce potential <br />impacts from asbestos - containing materials on site. None of the paint would quality as LBP given the concentration of <br />lead in paint observed. Based on the Phase I ESA, no recognized environmental conditions (RECs) have been identified <br />in connection with the site, and no further mitigation is necessary. <br />e -f) There are no airports or airstrips in the vicinity of the project site. Oakland International Airport is approximately 2 <br />miles northwest of the project site and Hayward Executive Airport is approximately 4 miles to the southeast. <br />g) The project would not alter existing emergency response procedures, nor impose a substantial demand on emergency <br />response personnel. Accordingly, the proposed project would not impair implementation or interfere with emergency <br />response in the project vicinity and therefore have no impact. <br />h) The project site is in an urbanized setting, remote from wildlands. Therefore, safety hazards from wildland fires would <br />have no impact on the proposed project, therefore, no mitigation is required. <br />a. Violate any water quality standards or waste discharge <br />X <br />4, 5, 8 <br />requirements? <br />b. Substantially deplete groundwater supplies or interfere <br />X <br />4, 5, 8 <br />substantially with groundwater recharge such that there <br />would be a net deficit in aquifer volume or a lowering <br />of the local groundwater table level, e.g., the <br />production rate of pre - existing nearby wells would <br />drop to a level which would not support existing land <br />uses or planned uses for which permits have been <br />ranted? <br />C. Substantially alter the existing drainage pattern of the <br />X <br />4, 5, 8 <br />site or area, including through the alteration of the <br />course of a stream or river, in a manner which would <br />result in substantial erosion or siltation on- or off -site? <br />d. Substantially alter the existing drainage pattern of the <br />X <br />4, 5, 8 <br />site or area, including through the alteration of the <br />course of a stream or river, or substantially increase the <br />rate or amount of surface runoff in a manner which <br />would result in flooding on- or off -site? <br />e. Create or contribute runoff water which would exceed <br />X <br />4, 5, 8 <br />the capacity of existing or planned storm water <br />drainage systems or provide substantial additional <br />sources of polluted runoff? <br />f. Otherwise substantially degrade water quality? <br />X <br />4, 5, 8 <br />g. Place housing within a 100 -year flood hazard area as <br />X <br />4, 5, 8 <br />mapped on a federal Flood Hazard Boundary or Flood <br />Insurance Rate Map (FIRM) or other flood hazard <br />delineation map? <br />2450 Washington Avenue Apartments 13 October 2011 <br />
