The SCAQMD requires at least 3 samples from each type of construction <br />material (i.e., different type of flooring or ceiling material) used in the buildings. Based on the <br />assumption that up to 3 different types of construction materials have been used in each unit <br />(roof, ceiling, flooring).. GCE estimates that at least 9 samples will need to be collected from the <br />ceiling, roof, 'and floo~g of the single family propertie~ for analysis. GCE assumes up to four <br />units for the multi-family properties and a common roof; therefore, 27 samples will be collected <br />from each multi-family. residential property for analysis. The actual number of samples may be <br />different bas~ on our site visit. . <br /> <br />The samples will be collected by a GeE AHERA-certified staff. The samples will be analyzed <br />using US EPA Method 6001R-93-116. <br /> <br />The results cif the survey will be provided to the City in the a letter report, or as a part of the <br />Phase I ESA report, whichever the City prefers. The approximate sampling locations will be <br />marked on the floor plan for the dwelling, provided by the City, and will be included in the <br />report. The ~rt will. also include a brief discussion of our findings, copies of the laboratory <br />reports and chain of custody documents. <br /> <br />Lead Sampling and Analysis <br /> <br />At this time the State of California does not have any requirements for pre-demolition waste <br />survey and sampling. Therefore to provide the City with an estimated cost, GeE assumes three <br />types of cOnstruction materials and bulk sampling after demolition to characterize the <br />construction debrislwaste. <br /> <br />GeE estimates that at least 30 samples will need to be collected from the units for analysis. The <br />actual number of samples may be different based on our site visit. <br /> <br />The samples will be collected by a qualified staff, and will be analyzed for total lead using <br />US EPA Method 7420, <br /> <br />The results of the survey will be provided to the City in a letter report, or 8S a part of the Phase I <br />ESA report,' whichever the City prefers. The approximate sampling locations will be marked on <br />the floor pliln for the dwelling, provided by the City, and will be included in the report. The <br />report will aJso include a brief discussion of our findings, copies of the laboratory reports and <br />chain of custody documents. <br /> <br />2.0 SCHEDULE <br /> <br />Barring unforeseen ci~umstances and lengthy response time from agencies, GeE plans to complete <br />the scope of worle fo~ Phase I ESA and lead and asbestos sampling and testing and submit our <br />report for each property in approximately three to four weeks.
