RE: SAID: 24471 820 North 42 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 820 North 42 Street along with a LBP Fact Sheet that provides information about risks associated with lead exposure. 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 EPA using the above criteria indicated that a structure on your property IS eligible for paint stabilization.

### 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 stabilized, 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 affect the development and behavior of young children. If you have children less than seven years of age living in your home, we strongly recommend that you contact your doctor or the Douglas County Health Department at (402) 444­ 7825 and arrange to have their blood tested.
If you have any questions or concerns, please contact the EPA Public Information Center at (402) 731-3045.
Sincerely,

Pauletta R. France-Isetts Project Coordinator Environmental Protection Agency
