Viburnum Trend Lead Haul Roads Superfund Site – Operable Unit 2, Viburnum, Iron County, Missouri - Fact Sheet, March 2020
Administrative Record File Available and Public Comment Period
Engineering Evaluation/Cost Analysis for Non-Time-Critical Removal Action
INTRODUCTION
The U.S. Environmental Protection Agency (EPA) Region 7 is soliciting public input on the Engineering Evaluation/Cost Analysis (EE/CA) for the Viburnum Trend Lead Haul Roads Superfund Site, Operable Unit 2 (OU2), also known as the St. Joe Minerals Corp. – City of Viburnum Site (Viburnum OU2). See below for How to Comment.
To protect human health and the environment, EPA is overseeing evaluation of alternatives for a potential removal action to address lead contamination in residential yards and child high-use areas. The Viburnum OU2 site (site) includes the city of Viburnum and additional nearby areas Lead is the main contaminant of concern at this site, which was likely distributed throughout the city during decades of mining, milling and transporting of lead ores and concentrates. (Learn more about lead and public health below.)
SITE OVERVIEW
EPA identified Doe Run Resources Corporation, or Doe Run, as the potentially responsible party (PRP) responsible for the lead contamination found at this site. Beginning in 2005, EPA and Doe Run entered into an agreement for Doe Run to begin cleaning up lead-contaminated residential properties in Viburnum. A Preliminary Assessment conducted by Doe Run and EPA in 2006 determined that over 200 residential properties were eligible for cleanup. A time-critical removal action has been completed for residential properties and child high-use areas determined to have sensitive residents and/or higher concentrations of lead in soil that had concentrations of greater 1,200 parts per million (ppm).EPA and the PRP plan to address the remaining residential properties and child high-use areas with lead concentrations of less than 1,200 ppm in soil (that were without sensitive residents) through a non-time-critical removal action. EPA is soliciting public input on the EE/CA for a potential non-time-critical removal action to clean up the remaining properties. (See site map at right.)
EE/CA OVERVIEW
An EE/CA is a study completed in advance of Superfund cleanups for non-time-critical removal actions. The EE/CA looks at environmental conditions and ways to clean up contamination. It identifies the goals for the cleanup and reviews the cost and feasibility of the cleanup options (also known as alternatives). The PRP, Doe Run, prepared the EE/CA to study removal options to address the contamination.
-
No Action
- Institutional Controls
- Public Health Actions
- Containment of Contaminated Soils
- Contaminated Soil Removal
-
Excavation of soils with lead greater than 400 ppm to a depth of 6 to 12 inches or until the subgrade soil concentrations are less than 1,200 ppm. Clean soils will replace excavated soils. Excavated soils will be disposed of at the Viburnum tailings facility or appropriate Subtitle C and/or D landfill.
- At properties where excavation occurs, the owner will be provided health educational materials.
SITE BACKGROUND
The Viburnum OU2 site is located in northwestern Iron County with smaller portions existing within Crawford and Washington counties in southeastern Missouri. It is part of what is commonly known as the New Lead Belt mining district, or Viburnum Trend, where lead production began around 1960. The Doe Run Resources Corporation – Viburnum Division (formerly St. Joe Minerals Corp. – Viburnum) is located in and near the city of Viburnum. The Viburnum Division includes four mines where ore was brought to the surface.
During construction, development, and early operation of these mines, it was not uncommon for lead-contaminated materials such as tailings and/or poor rock to be used for construction materials in building of the city of Viburnum, which was done by the St. Joe Minerals Corp. to support mining operations. As a result of mining-related activities that have occurred in and around the city, lead and lead compounds have been released into the environment in quantities sufficient to present an imminent and substantial danger to public health and welfare.
ABOUT LEAD AND PUBLIC HEALTH
Lead is a toxic metal that is harmful if inhaled or swallowed. Lead is classified by EPA as a probable human carcinogen and is a cumulative toxicant that affects multiple body systems and is particularly harmful to young children. Lead exposure can pose serious health risks, particularly for children 7 years old and younger, pregnant women, and nursing mothers. Pregnant women and nursing mothers should also avoid exposure to lead to protect their children.
-
Slowed physical growth
- Hearing problems
- Nervous system and kidney damage
- Learning difficulties
- Behavioral problems, including hyperactivity (easily excitable or upset, unable to concentrate, short attention span)
- Decreased intelligence (I.Q.) scores
Children are more sensitive to lead than adults and can develop lifelong learning disabilities and behavior problems from lead exposure. Children 7 years old and younger are most at risk from developing health effects from exposure to lead. It is important that children in this age range be tested annually because lead-poisoned children do not always look or act sick. The only way to know if your child has elevated blood lead levels is to have his or her blood tested.
EPA encourages parents to have their children tested for lead exposure. Talk to your pediatrician, general physician, or local health department about what you can do and about testing your child. Your doctor can do a simple blood test to check you or your child for lead exposure.
