1.1.1 Incident Category
CERCLA incident category: Dioxin (D)
1.1.2 Site Description
1.1.2.1 Location
The Site is located in the extreme northeast corner of the proposed Strecker Forest Subdivision at 173 Strecker Road, Wildwood, Missouri, as well as a portion of the Bliss-Ellisville Site, west of the Mid-America Horse Arena at 149 Strecker Road, Ellisville, Missouri, and is approximately one acre in size. Coordinates for the Site are latitude 38.600100N, longitude 090.604100W. The Site has also been called the "northeast area" of the proposed Strecker Forest Subdivision in prior reports.
1.1.2.2 Description of Threat

2. Current Activities

|
|
2.1 Operations Section
|
|
|
|
2.1.1 Narrative
Due to the presence of elevated levels of dioxin in soil at the Site, the EPA is conducting a time-critical removal action to reduce potential exposure to nearby human populations, animals and the food chain. Removal criteria is set by the site's Action Memorandum. Soils exceeding 820 parts per trillion (ppt) from 0 to12 inches below ground surface (bgs) will be removed. At depths equal to or greater than 12 inches bgs, removal of soils will continue until a residual dioxin concentration of less than three times the site-specific cleanup goal, or 2,460 ppt, is reached.
Samples collected at this Site are being submitted to a laboratory in North Carolina for dioxin analysis. Turn-around between the time a sample is received by the laboratory and the time results are made available is 72 hours.
Dioxin-contaminated waste generated at this site is being treated as F027 dioxin-bearing waste. The Universal Treatment Standard (UTS) for F027 dioxin-bearing waste is 1 ppb (40 CFR § 268.48). The alternative Land Disposal Restrictions (LDR) treatment standard (40 CFR § 268.49) states that treatment to achieve constituent concentrations less than ten times the UTS is not required. Dioxin-contaminated waste generated during the removal, up to concentrations of 10 ppb 2,3,7,8-TCDD, will be transported to an off-site RCRA-permitted hazardous waste facility located in Waynoka, Oklahoma, for proper management.
Dioxin-contaminated materials with an average concentration greater than the alternative LDR treatment standard for contaminated soil will be managed by a facility capable of meeting the UTS for F027 dioxin-bearing waste.
Contaminated soil is being direct loaded into the red 25-cubic-yard roll-off boxes. Boxes are lined prior to filling and covered immediately after being loaded.
2.1.2 Response Actions to Date
August 4 through August 8, 2014
1) Crews finalized restoration activities within the work zone.
2) Two remaining boxes of waste will be shipped off next week.
3) Site office and remaining equipment will be demobilized next week as well.

Waste Box Inventory (as of August 8, 2014)

Boxes awaiting shipment to Waynoka: 0
Boxes exceeding concentrations of 10 ppb 2,3,7,8-TCDD that have been transported to the off-site hazardous waste facility located in Saint-Ambroise, Quebec, for treatment and disposal: 15
Boxes awaiting shipment to Saint-Ambroise: 2
Boxes on site awaiting analytical profiling: 0

2.2.1.1 Planned Response Activities
Two waste boxes remain to be shipped off-site.
2.2.1.2 Next Steps
Crews and equipment will be demobilized.
2.2.2 Issues
No issues to report during this operational period.

|
2.3 Logistics Section
|
|
|
|
The existing road back to the work zone was improved with a 3-to-5 inch gabion stone overlaying a black geotextile fabric. The rock and fabric are used to allow the large equipment access to the back of the property. Due to the way the work zone is situated, including site drainage, it was determined that improving the existing road was the best option. In addition to on-site considerations, the impact on local residents was also considered. The path chosen allows for the least direct impact on local residential properties.
