DUDEK <br />limits will meet the project objectives. The findings of the sampling will be presented in a standalone report <br />or incorporated into a Phase II report. <br />Laboratory Analysis <br />Dudek will partner with Jones and Eurofins Calscience to provide laboratory analytical services. Both labs <br />are certified by the California Environmental Laboratory Accreditation Program. Eurofins Calscience is <br />also certified by the National Environmental Laboratory Accreditation Program and American Industrial <br />Hygiene Association Laboratory Accreditation Program. All laboratory analyses will be performed in <br />accordance with applicable EPA Methods and Contract Laboratory Program protocols. Any deviations <br />from the EPA Methods will be documented. All samples will be collected in laboratory -supplied containers <br />with proper preservative, properly labeled (unique sample number, date, time, site name, sampler name, <br />and requested analysis), logged on a chain -of -custody, placed in an ice -chilled cooler, and transferred to <br />the laboratory by field personnel or via laboratory courier. Aurora will partner with LA Testing/EMSL and <br />Eurofins EMLab P&K for asbestos, lead, and mold laboratory analytical services. <br />Reports <br />Reports will include a statement of the objective, site background information, description and rationale <br />for the investigation, deviations, methods used, data evaluation and comparison to regulatory screening <br />levels, data interpretation, figures, tables, laboratory analytical reports, and any additional supporting <br />information. Reports will be prepared under the direct supervision of a professional engineer or <br />professional geologist. <br />Agency Coordination <br />Dudek will coordinate with local and state officials, as necessary, to facilitate project objectives. <br />Coordination with agencies may include obtaining permits for subsurface investigation work, <br />coordinating field work schedules on public properties, and entering into a voluntary oversight <br />agreement to ultimately obtain certified regulatory closure. Dudek will not contact any property owners, <br />regulatory agencies, or other entities without expressed permission from the City. <br />Category II <br />Hazardous Building Materials Surveys <br />Aurora will survey and test buildings, storage vessels (tanks, containers, drums, etc.), and stored <br />materials for the presence of hazardous waste or materials. The survey and testing may include visual <br />inspection for the presence of suspected lead -based paint (LBP) and asbestos -containing materials <br />(ACM), identification of potential PCB -containing equipment and materials, identification of universal <br />waste, contents of materials stored in vessels, and assessment of buildings where hazardous materials <br />or wastes are stored. <br />Surveys typically consist of the collection and submittal of samples from homogeneous areas for <br />asbestos analysis by polarized light microscopy. The LBP assessment of suspect materials will be <br />performed using X-ray fluorescence technology; paint chips of damaged areas may be collected for <br />laboratory confirmation. Depending on the constituents of concern, additional sampling may be <br />performed to categorize other waste materials at a site (universal waste, PCBs, etc.) <br />Various Environmental Services 15 <br />
