The $CAQMD requires at least 3 samples ftomeach type of construction <br />material (Le., 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, ceilíng, flooring), GCE estimates that at least 9 samples will need to be collected from the <br />ceiling, roof. and flooring of the single family properties for analyst!. 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 ror anal)'1lis. The actual number of samples may be <br />different based on our site visit. <br /> <br />The samples will be collected by an AHERA-<:ertified professional. The samples will be <br />analyzed using US EP A Method 6001R-93-ll6. <br /> <br />The results of the survey will be provided to the City ina letter report,. or as a part of the Phase I <br />ESA report,. whichever the City prefers. The approximate SIIIIIpling ,locations will be marked on <br />the floor plan for the dwelling, provided by the City, and will be included in the report. The <br />report will also include a brief discussion of oW' findings, copies of the laboratory reports and <br />chain of custody documents. ' <br /> <br />Lead SampUng and Analysis <br /> <br />At this time the State of California does not have any requirements for pre-demo1ition waste <br />survey and sampling. Therefore to provide the City with an estimatl:d cost, GeE assum~ three <br />types of construction màterials and bulk sampling after demolition to characterize the <br />construction debris/waste. , ' <br /> <br />GeE estimates that at l~ 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 as a part of the Phase I <br />ESA report, whicheva- thci City prefers. The approximate sampling locations will be marked on <br />the floor plan for the d~lling, provided by the City, and will be included in the repon. The <br />repon will also include a brief discussion of our findings, copies of the laboratory reports and <br />chain of custody documents. ' ' <br /> <br />2.0 <br /> <br />SCHEDULE <br /> <br />Barring unforeseen circumstances and lengthy resp0n3e time from agencies, GCE plans to complete <br />the scope of work for Phæe I ESA and lead and asbestos sampling and testing and submit our <br />report for each property in approximatl:ly three to rour weeks.
