INTRODUCTION

  • Weldon Spring is the site of a former chemical and radiological facility

  • This site included a manufacturing facility with disposal ponds on site

  • It also included a quarry that was used for disposal of waste

  • MoDOT has two highways, Routes D and Route 94 that traverse the area

  • MoDOT also has a maintenance lot next door to the disposal cell

Route 94 culvert l.jpg

Route 94 Culvert

  • Installed by the army under 40 feet of fill

  • Consists of corrugated metal that is rusting

  • Culvert is contaminated

  • Removal costs about $1 million

  • Fix and leave in place with future replacement when needed

60 inch X 225 feet

Route 94 Future Needs

  • After collapsed end was cut away

  • Water had undercut the end

Route 94 Culvert Downstream

  • Fill is washed away from around the culvert

  • This section broke away

  • Isn’t necessary for integrity of the highway

  • DOE’s discretion on what to do with it

Route D Culverts

  • Installed by Army

  • Consists of corrugated metal that was rusting

  • Believed contamination is under the culverts

  • Removal and replacement to be done next year

Route D Culverts

  • MoDOT’s contractor will uncover the culverts

  • DOE contractor will remove along with any contaminated soil

  • MoDOT will supply fill material


Working together l.jpg

Working Together

  • Missouri is the “Show Me State”

  • We need to see to accept

  • Several Missouri state agencies were involved

  • MoDOT, DOC, DNR, DNR Parks

  • DNR is the central contact


Central contact l.jpg

Central Contact

  • One central state contact

  • Everyone was kept informed

  • Easier to work with DOE and for DOE to work with the agencies

  • MoDOT concerned with protecting our employees and the public


Open comunicaton l.jpg

Open Comunicaton

  • MoDOT assigned one central contact within the department

  • Maintenance people were briefed

  • Design and construction to coordinate future efforts

  • DOE provided educational opportunities for employees


Future route d improvements l.jpg

Future Route D Improvements

  • Widen Route D next spring

  • Culvert replacement will be coordinated

  • Route D will be shut down for two days

  • MoDOT’s contractor will remove the overburden

  • DOE will remove the culverts and any contaminated soil

  • MoDOT will replace the fill and culverts and finish the project


Future route d improvements18 l.jpg

Future Route D Improvements

  • Disposal of the culverts will be determined

  • If they are not contaminated they will be recycled

  • DOE has offered to be present at the pre bid meeting to answer any questions from contractors


Future route 94 improvements l.jpg

Future Route 94 Improvements

  • Route 94 cannot be shut down

  • Shoulders are being added to Route 94

  • Culvert replacement or repair will be coordinated with DOE

  • MoDOT will continue to work with DOE
