Fact Sheet

September 2006

Time-Critical Removal - Annapolis Lead Mine Site, Annapolis, Iron County, Missouri

INTRODUCTION

The U.S. Environmental Protection Agency will return to the community of Annapolis during the weeks of September 18 – 29, 2006. The purpose of the visit is to address lead contaminated soil at the Annapolis Lead Mine Site. Hazardous substances have been detected in the surface sediments and soil at the site. They have also been detected in soil, sediment and water down gradient from the site. EPA plans to stabilize the lead contaminated waste mine tailings on-site as a solution to address these threats.

CURRENT SITE CONDITIONS

The site property boundary is roughly rectangular in shape. It is bordered to the south and east by wooded uplands. A residential plot lies to the north and Iron County Road number 138 runs along the western boundary. The dominant features at the site include a 4-acre capped tailings repository, and building foundations that are remnants of the former mining operations.

One of the remaining mining building remnants has been modified for residential use and is currently vacant. A fence and gate borders the front of the property, providing limited access by the public to the contaminated site areas. The tailings repository has been eroded due to surface runoff. Screening samples taken from soil in drainage areas around the repository cap and the point of entry into Sutton Branch Creek contain lead in excess of 5000 parts per million.

The material washed from the site is ultimately deposited as clay and small particles on the otherwise coarse-grained stream beds. This particle size tends to accumulate in slower moving reaches of the streams, i.e., in the pools where human recreational activities take place.

PROPOSED ACTIONS

EPA is the lead Agency on this project. The proposed activities will include, but are not limited to:

After completion of the proposed removal action and stabilization of the repository cap, EPA and Missouri Department of Natural Resources will work together to put in place controls to prevent future exposure to hazardous substances. After the removal is completed, Missouri Department of Natural Resources will prepare a post-removal site control plan. EPA and MDNR will seek to obtain environmental easements or other legal restrictions to prohibit digging or other activities that may result in exposure to hazardous substances remaining at the site after the removal action.
