MADISON COUNTY MINE MISSOURI EPA ID# MOD098633415 EPA Region 7 City: Fredericktown County: Madison County Other Names: 07/03/2007 SITE DESCRIPTION The Madison County Mines Project is located in southeastern Missouri near Fredericktown in the Old Lead Belt where heavy metal mining has occurred since the early 1700s. Past mining operations have left, at least, thirteen [13] identified major tailings and chat deposits from smelting and/or mineral processing operations within the county and there may be other piles or other locations where these deposited materials have been placed. These materials may have been moved by erosion, both wind and water, or relocated by other means to other locales throughout the county. The tailings contain elevated levels of lead and other heavy metals which pose a threat to human health and the environment. In addition, these deposits have contaminated soils, sediments, surface water, ground water, and are impacting ecological systems. At several locations and, somewhat throughout the area, exposure of the most endangered groups (young children, pregnant women, and senior adults) to these contaminants is on-going. Site Responsibility: The site is being addressed through Federal and Responsible Party actions. NPL LISTING HISTORY Proposed Date: 04/30/2003 Final Date: 09/29/2003 Deleted Date: ------- THREATS AND CONTAMINANTS m Heavy metals resulting from the mining and processing of lead ore are the contaminants being investigated and addressed. Exposures to lead, cadmium, and zinc can represent a significant risk to the health of young children, pregnant women, and the elderly, and the surrounding natural environment. The media being evaluated and addressed include: chat and tailings piles; residential yards; public areas; drainage ways; road, street, and highway right-of-ways; ground water; surface water; sediments; and air and water erosion. CLEANUP APPROACH Response Action Status Initial Actions: Residential yard soil evaluations have been completed. Sampling of approximately 3100 homes, which accounts for about two-thirds of the residencies in Madison County, have been completed and the effort continues. Approximately 852 residential yard soils have been determined to be at or above the lead action level [1200 milligrams per kilogram or parts per million] and approximately 804 had been cleaned up by the end of 2006. Site Studies: A characterization study is underway at Operable Unit #1 (OU1) which is the Northern portion of the site. It is being conducted by Potentially Responsible Parties (PRPs) with oversight by EPA for the presence and concentrations of contamination, and risk to both human health and the ecology. Negotiations are ongoing with other PRPs to conduct a characterization study on OU2 which is another area of the site. A Remedial Investigation which covers OU3 - OU6 of the site should be completed by the end of 2007. A Feasibility Study (FS) for a Interim OU3 Remedial Action is also in progress and should be completed at about the same time. An Interim Proposed Plan is soon to be publicly issued to obtain community input for the Record of Decision (ROD). The Proposed Plan addresses remediation ------- of all residential yards and public areas in Madison County. The ROD for this interim action is scheduled to be completed in this fiscal year [before 9-30-07], The Remedial Design (RD) is scheduled to begin this winter with construction preparation, bidding and construction contract awarding completed in late winter-early spring. The Remedial Action (RA), which is the pivotal driver for remediating all yards, is scheduled to begin next summer and continue for an estimated five [5] years. An FS for the remaining remedial action on OU3 is scheduled to be issued this fall. Site Facts: In 1999, approximately 16% of the children tested in Madison County had lead poisoning. In 2005, that percentage was lowered to 6% which is mostly due to efforts by the Madison County Health Department in providing health education and to the removal of contaminated soil from residential properties. ENVIRONMENTAL PROGRESS Two time-critical removal actions were completed in October, 2006. These removals cleaned-up properties where lead-contaminated soils were creating an unacceptable risk to young children. Sampling of approximately 3,100 homes, which accounts for about two-thirds of the residencies in Madison County, has been completed and the effort continues. Approximately 852 residential yard soils have been determined to be at or above the lead action level [1,200 milligrams per kilogram or parts per million] and approximately 804 properties have been cleaned up. The actions include day-care facilities, playgrounds, parks, and other properties used frequently by young children. An Ecological Risk Assessment, which identified and quantified impacts to the ecology by releases from mining wastes, has been completed and is available at the repositories listed below. ------- COMMUNITY INVOLVEMENT A Community Involvement Plan serves as a support vehicle at this site, defining "who, what, when, where, and why" EPA has a presence in Madison County. The Madison County Environmental Roundtable was established as dialogue forum for EPA, health officials, state representatives, elected officials, and local interested persons. This group has remained active since its formation and meets every other month. EPA also has a toll-free telephone number for the Regional Office in Kansas City, Kansas to give the public easy access to site representatives. ------- SITE REPOSITORY Fredericktown Branch of the Ozark Regional Library 115 South Main Street Fredericktown, Missouri 63645 573/783-2120 Debby Anderson - Librarian Superfund Records Center 901 N. 5th St. Kansas City, KS 66101 Mail Stop SUPR (913)551-7166 REGIONAL CONTACTS SITE MANAGER: E-MAIL ADDRESS: PHONE NUMBER: COMMUNITY INVOLVEMENT COORDINATOR: PHONE NUMBER: E-MAIL ADDRESS: STATE CONTACT: PHONE NUMBER: John Cook/SUPR/R7/USEPA/US cook, j ohn@epa. gov (913)551-7716 Debbie Kring/OEP/R7/USEPA/US (913)551-7725 kring.debbie@epa.gov Gregory Bach (573)431-5322 Gregory.Bach@dnr.mo.gov MISCELLANEOUS INFORMATION STATE: MO 0701102 CONGRESSIONAL DISTRICT: Missouri 5th EPA ORGANIZATION: SFD- MODIFIC ATION S Created by: Lynette Created Date: 11/16/2005 04:02 PM Motl ey/SUPR/R7/U SEP A/U S Last Modified by: Debbie Last Modified Date: 07/03/2007 04:57 PM Kring/OEP/R7/U SEP A/U S ------- ------- |
