� , . �. ' � � . � � . � � Seven"Lead Check"swab samples were taken of suspect paints identified iNon the subjecl propeRy. Four samples indicated a positive resutt for the presence o(lead. Chip samples were taken of those paints with a posilive 'Lead Check" indication and analyzed for lead content by Atomic Absorplion (AA) methodology. The foilowing samples ,.. exceeded the HUD lead-based paint guideline oi 0.5°h Iead by weight: . All whNe interior and exterior paims showed a posRive"Lead Check"swab indication. SubsequeM AA analysis showed the presence of lead in percentages ranging from 7.6% to 38%. All other paints showed a negative ' °Lead Check"swab indication.

If the building is to be renovaled or remode�d there are procedures regarding the disturbance or removal of the lead•based paints that�be followed (.e. inftial air monitoring, Gearance sampling, etc.). These procedures wn be found in HUD-0006700 Guidelines for the Evalua6on and Conbol of Lead-9ased Paint Hazartis in Housing. It is not required that these regulationslprocedures be ulilized on this projed, however because these are the only available guidelines for the removal of lead-based paints PRE feels it necessary to inform you of the existence of these guidelines. The only rvles or regulations that currently apply to lead-based paints are WAC 296-155-17603 Scope' and WAC 296-155-17607 Permissible Exposure Limit". InNiai air moniloring musl be pertormed on employees doing renovation or remodeling work in aieas found to have materials containing lead. Because the WAC codes do not specify an amount of lead that would establish a material as lead containing, R musi be assumed that a malerial containing a�lead is regulated by these codes. Prior to disposal,the wasle stream generated from the renovation or demolition of all structures must be analyzerl using EPA Method 7371 - Toxicity Charaderistic Leachale Procedure (fCLP) - Lead by Atomic Absorption Spectrophotometry. Wasle found to have a leachabilily greater than or equal to 5 ppm must be disposed of as hazardous waste;waste with a leachability of less than 5 ppm may be disposed of as solid waste. Swab sampling of the paints In this building was intended to identify those paints that might contain lead. Samples identified as positive by the swabs may be chip sampled lo establish the actuai percentage of lead in the paint. Identifying paints wilh high lead contents aids in the separation of materials that may affect the TCLP resutts of the demolitioNrenovation wasle stream. Low percentages of lead can still exist in those paints considered negative by swab sampling. Painis with such low levels of lead would not be considered lead-based paints by the HUD Guidelines, and it is highly unlikely that they couid negaiively affect the TCLP sample of the wasle stream from the associated structure. However, as per!he WAC codes,any presence of lead i�paint would require air monRoring be performed prior to and during renovatfon or demolilion activities. • WAC 296•166•17603 Seope.WAC 286•156•1�6,L�d,appiies to atl construclion worfc where an empbyee may be oaupationaM e�osed to lead.
