Dear Owner/Resident: Von R Trimble Omaha, Nebraska 68110 2121 Lothrop Street

2121 Lothrop Street

A Lead Based Paint assessment was recently performe d 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 signific ant quantity of LBP is present on the exterior surface of structures, where deteriorating paint co nditions (peeling, flaking, cracking, etc) exist that might increase lead concentrations in the yardabove acceptable levels. Enclosed are the LBP assessment sheets for 2121 Lothrop Street. The EPA has developed paint stabilization eligibility criteria that involve mea suring the amount of deteriorated LBP on a structure and calculating the concentration of leadin 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 th e lead content in the deteriorated paint was measured using an X-Ray Fluorescence instrument. The data obtained during the LBP assessment was use d 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 deterioratingLBP on a structure is assumed to fall onto the ground surface within six feet of the foundation an d be uniformly mixed with the top one inch of soil. The estimated lead concentration in the so il 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 pote ntial for recontamination of soil to occur. Paint stabilization is being offered at only those househ olds with the most severe LBP problems, particularly where children under the age of seven reside. Lead-Based Paint (LBP) Assessment

The LBP assessment performed by the EPA using the a bove criteria indicated that your house IS NOT eligible for paint stabilization. RE: SAID: 430
