r ■� R■ KLEINFELDER File No. 20-3978-01.W10 July 26, 1997 3. A copy of this report should be submitted to the San Joaquin County Public Health Services Department Environmental Health Division (PHS/EHD) and the Central Valley Office of the State of California Regional Water Quality Control Board (RWQCB) by the Atherton-Kirk for their review and consideration. A letter of"no further action" should be requested of both agencies for the area which is the subject of this report. 4.16 Administration Buildinty ACBM Survey(File No 20-3978-01.A01) At the time of Kleinfelder's Phase I ESA, a recommendation for an asbestos containing building materials (ACBMs) survey was made. However, it was not relayed to our firm at that time, that a firm had already been contracted for the work. Therefore, Kleinfelder's work was limited to a survey for lead based paints (LBPs) and a limited sampling of some pipe wrap material for ACBMs. Based on the results of the lead based paint survey and limited sampling for asbestos containing building materials, Kleinfelder had the following recommendations detailed in our report "Lead Paint Survey Results, Administration Building and Beet Seed Warehouse, Former Spreckels Sugar Plant, 18800 South Spreckels Road, Manteca, California" dated December 3, 1996: 1. At the time of building demolition, all work with a material containing lead above the analytical laboratory's reporting limit must be treated as having a potential to exceed Cal- OSHA's Permissible Exposure Limit (PEL) for lead of 50 µg/m' air unless it can be shown by one of several methods (see report) to produce air concentrations under the PEL. 2. Any demolition work that will disturb lead-based paint will be subject to the Lead Construction Standard, and should be properly handled by a licensed and qualified contractor. 3. If the buildings are to remain on site, then the building occupants should be informed of the presence and location of LBPs as part of a Hazard Communication Program. Disturbance of the LBPs (including sanding, scraping, grinding etc....) should be discouraged. Deterioration of the paint in the building should be reported to the management and/or on-site safety supervisor. 10-3978-01.W1012017L155 Page 31 of 50 Copyrighl 1997,Kleinfelder,Inc.
