0 <br />LBP Testing and Assessment <br />Proposal for <br />Various Environmental Services <br />Page 24 <br />August 1, 2022 <br />A -Tech utilizes trained Certified California Department of Public Health (DPH) Inspector/Assessors and <br />DPH Project Monitors for all lead inspections, hazard assessments, project monitoring and clearance <br />monitoring services. For Lead Based Paint (LBP) inspections of pre -designated areas, our DPH Certified <br />Inspectors/Assessors, will utilize an X-Ray Florescence (XRF) analyzer and screen all painted surfaces, <br />ceramic, and porcelain components by utilizing Cal-OSHA's and the U. S. Department of Housing and <br />Urban Development's (HUD) sampling protocols. If analysis of suspect components using the XRF is <br />not conclusive of presence of LBP, chip samples will be collected and analyzed by an AIHA accredited <br />laboratory, utilizing Flame Atomic Absorption (AAS), in accordance with current regulatory <br />requirements. We will summarize the results and procedures in an LBP Assessment Report that will <br />include (but not limited to) name of the inspector, date of inspection, all the XRF readings and their <br />location logs, paint chip sample collection procedures and locations, results of laboratory analyses and its <br />accreditation statement, and recommendations for next steps. If LBP was identified in any of the <br />materials, an abatement work plan will be prepared and submitted along with the assessment report for <br />execution by the abatement contractor. <br />LBP Abatement and Monitoring <br />For lead abatement or paint stabilization activities, we inspect the integrity of the containment, review <br />all applicable notification and/or submittal documentation, review all abatement worker certifications and <br />ensure a copy of the survey and work plan are on site during the work period. The project is monitored <br />continually to ensure no migration of LBP occurs and that proper engineering controls are implemented <br />as well as proper protective equipment are being utilized by the lead abatement contractor throughout the <br />project. Upon completion of the removal/stabilization project, our technicians conduct a final visual <br />clearance inspection and clearance sampling. Upon approval of the visual inspection, clearance wipe or <br />soil sampling is performed and sent to a certified laboratory that will analyze the samples using AAS. If <br />requested, A -Tech will also obtain and submit samples which will be analyzed for Waste Stream <br />Characterization (TCLP, TTLC and STLC) to determine disposal requirements for generated lead waste <br />on a project. <br />As it was described above, A-Tech's personnel will assist the City in overseeing abatement contractors' <br />activities. We will provide air monitoring and consultation on as -needed basis to ensure compliance with <br />all the applicable rules and regulations, such as SCAQMD Rules 1403, 1150, 1166, and 1466. We <br />understand that the City may be required to provide air monitoring during abatement and remediation <br />activities, including but not limited to monitoring for dust, asbestos fiber content, VOCs emission, and <br />any COPCs that might be emitted to the air by site disturbance. We have all the necessary equipment and <br />tools in-house to conduct all the air monitoring requirements of this contract, and our personnel have <br />experience utilizing PMlo, using either direct -read or datalogging particle counters, and photoionization <br />detectors (PID). Our qualified consultants will be available 24/7 to provide consultations to the City <br />regarding air monitoring and any other pertinent environmental issues. <br />0 A -Tech Consulting, Inc. <br />
