RFP #24-038A: On-Call Environmental Review Services for C HAM B E RS the Housing Division City of Santa Ana GROUP Lead-based Paint (LBP) Survey: The LBP Survey will be limited to the predominant style of accessible components that are present in the building. The survey will be performed using a direct reading x-ray fluorescent (XRF) device. Based on Converse's understanding of the property, and the client's needs, budget and schedule as presented,the following Scope of Services is proposed: 1. Visual survey of the areas for representative painted surfaces.Accessible areas will be surveyed.Samples of general building components (i.e.,visually identical surface paints)will be assumed to be representative of materials used throughout the building. 2. The limited survey is intended to identify representative painted surfaces.The survey is not intended to identify all painted surfaces or comply with HUD Guidelines, unless stated elsewhere in final project scope of work. The results of the survey will be evaluated to determine if lead is present in the surveyed paints.The XRF logs will be provided in the final report.The logs will contain the following information: paint color of component tested, type of substrate, lead concentration, and condition of paint. The results of the LBP Survey will be incorporated into the Asbestos Survey Report. Lead Risk Surveys: Converse will follow HUD Guidance Document Chapter 5 for Risk Assessment and Reevaluation. Scope will include: 1. Determine scope. 2. Interview residents and/or owners. 3. Survey building condition. 4. Determine whether units will be sampled and,if so,select units. 5. Conduct visual assessment. 6. Conduct dust sampling. 7. Conduct soil sampling. 8. Conduct paint testing as needed. 9. Sample tap water(optional). 10. Interpret the laboratory results. 11. Analyze data and discuss with client. 12. Prepare report. Limited Polychlorinated Biphenyls (PCB) Caulking Survey:The PCB Caulking Survey will be limited to the predominant style of accessible materials that are present at the building. Non-destructive sampling methods will be utilized as the structure is occupied. 1. Visual survey of the structure on-site for locations and condition of the caulk.Areas to be assessed include: • Caulk used to seal doors,windows and expansion joints including any areas where caulk was removed and/or replaced during past renovations. • Caulk found inside the building on the floor,windowsills, ledges,concrete joints, or other areas. • Interior halls and common use areas, particularly in areas where there is a potential for caulk to be touched or peeled away by a person. • Exterior areas, particularly in areas where there is a potential where the caulk may have impacted soil in a frequently used area such as a garden, play areas, bus stops and children pick up areas. 2. Bulk samples will be submitted to an accredited laboratory and analyzed by EPA Test Method 8082 on a standard turnaround time of 5 to 7 business days. 3. The limited survey is intended to identify representative caulking materials.The survey is not intended to identify all materials. The results of the survey will be evaluated to determine if PCBs are present in the collected and analyzed samples.The analytical test results will be presented together with the sample locations,a list of materials surveyed found to contain PCBs, and a field generated sample location map. Inventory of Other Hazardous Materials: Converse will inventory the following within the building: • Fluorescent Light Fixtures • Thermostats • Drums and/or containers of Hazardous Materials The fluorescent light fixtures will not be disassembled to access and observe the ballasts. Converse will assume one ballast is located within each florescent light fixture. All homogenous light fixtures will be assumed to be the same throughout a particular building. = Est 'sre�` 1979 c:up,
