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 4188 Cass 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,
