Taylor Property(4/21/2021) Page 4 of 4 • Lead results were also reportedly above the EPA's limit for dust lead on floors in two locations. However, as noted in the report, samples were not collected from flooring but instead from an attic space and pool table. EPA's Hazard Standards and Clearance Levels for Lead in Paint, Dust and Soil provides clearance levels of various surfaces in a residential property. The December 2020 final rule lowered the clearance levels as follows: floors at 10 micrograms per square foot (10 pg/ft2)and windowsills at 100 pg/ft2. If comparing to floors, results appear to exceed the clearance level, if compared to windowsills (similar height to sample location at pool table), results do not exceed the clearance level. Additionally, information on other potential sources, such as lead paint, etc.were not included in the evaluation. Such information would be deemed necessary to assist in determining the source of the lead identified. • FACS' assessment did not include sampling of metals. Instead, smoke related particulates were sampled and used as general indicators of potential deposition of smoke related particles and any contaminants that may be associated with them (e.g., metals, polycyclic aromatic hydrocarbons, etc.), although such associations are not well studied. In summary, Indy Safety concluded that based on the investigation, including wipe sample results, the subject residence required cleaning. Specifically, due to visual inspection and results of heavy metals (cadmium and lead)sampling and combustion by-product sampling. Recommendations for cleaning of the entire property were provided. As noted above, no comments regarding on-site findings were provided in the report. Based on review of the provided report, as well as FACS' investigation, FACS does agree that areas of the interior and exterior of the home were impacted by the wildfire event, including the attic space and shed. The only area in which recommendations differ is interior surfaces located further away from entry points (>5ft) in the main home. Based on FACS' comprehensive investigation, wildfire smoke impact is not suspected on surfaces further away from the home, based on sensory findings as well as surface sample results which indicated "common" levels (non-detectable to trace levels; <1%)of smoke related particulate in the sampled dust. Review of Indy Safety's report does not define locations in which surface samples were collected. Therefore, it is unclear if cleaning recommended by FACS would include such areas. The Indy Safety report does not provide sufficient information or data to prove additional cleaning above FACS' recommendations are warranted at this time. Additionally, FACS recommends an evaluation to determine the source of the lead identified to determine if a lead hazard exists in the home. FAGS findings and discussion are based on the data available. Additional documents of information provided to FACS may result in differing opinions.
