### September 23, 2011 Alejandro S Gonzalez 2011 W Street Omaha, Nebraska 68107 RE: SAID: 46824 2011 W Street Lead-Based Paint (LBP) Assessment Dear Owner/Resident: A Lead Based Paint assessment was recently performed on your property by the U.S. Environmental Protection Agency as part of the Omaha Lead site investigation. The purpose of this assessment is to determine whether a significant quantity of LBP is present on the exterior surface of structures, where deteriorating paint conditions (peeling, flaking, cracking, etc) exist that might increase lead concentrations in the yard above acceptable levels. Enclosed are the LBP assessment sheets for 2011 W Street. The EPA has developed paint stabilization eligibility criteria that involve measuring the amount of deteriorated LBP on a structure and calculating the concentration of lead in soils around the home that would result if all of the identified deteriorated paint were to fall to the ground and uniformly mix with the soil under certain assumptions. During the LBP assessment, the areal extent of the deteriorated paint observed on structure surfaces was estimated and the lead content in the deteriorated paint was measured using an X-Ray Fluorescence instrument. The data obtained during the LBP assessment was used to estimate the increase in soil lead concentration that would result if all of the deteriorating paint identified in the assessment were to fall to the ground and mix with surface soil within six feet of the foundation of the structure. For purposes of this calculation, the deteriorating LBP on a structure is assumed to fall onto the ground surface within six feet of the foundation and be uniformly mixed with the top one inch of soil. The estimated lead concentration in the soil potentially caused by the deteriorating LBP provides a measure of the severity of LBP deterioration on individual structures. The EPA uses these criteria to rank properties based on the potential for recontamination of soil to occur. Paint stabilization is being offered at only those households with the most severe LBP problems, particularly where children under the age of seven reside. The LBP assessment performed by the EPA using the above criteria indicated that your house IS NOT eligible for paint stabilization.
