Dear Owner/Resident: Dennis D Dowd Omaha, Nebraska 68131 640 North 42 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 640 North 42 Street along with a LBP Fact Sheet that provides information about risks associated wi th lead exposure. The EPA has developed paint stabilization eligibility criteria that invol ve measuring 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. The LBP assessment performed by EPA using the abovecriteria indicated that a structure on your property IS eligible for paint stabilizatio n. 640 North 42 Street Lead-Based Paint (LBP) Assessment RE: SAID: 2125

Para información en español, llame al EPA Informati on Center (402) 731-3045. Sincerely,

Pauletta R. France-Isetts Project Coordinator Environmental Protection Agency If you have any questions or concerns, please contact the EPA Public Information Center at (402) 731-3045. The EPA stresses the importance of maintaining painted surfaces where any amount of LBP is present. The LBP Fact Sheet provides information pertaining to the EPA’s Exterior LBP Response Program. If your property is eligible for LBP stabilization and the LBP on the structures on your property has not yet been stabil ized, a representative from the EPA or the Omaha Lead Hazard Control Program will contact you to arrange for paint stabilization at your property. Exposure to lead contamination can adversely affectthe development and behavior of young children. If you have children less than seven year s of age living in your home, we strongly recommend that you contact your doctor or the Dougl as County Health Department at (402) 444- 7825 and arrange to have their blood tested.I I I Plan View
