1.1.1 Incident Category
Time Critical Removal Action
1.1.2 Site Description
The Site is a 2.8 acre lot with a 61,000 ft2 abandoned industrial building, formerly occupied by Wisconsin Die Casting, LLC, in a mixed residential, commercial, and industrial area. The Site building remains vacant and has fallen into disrepair, with continuous and persistent trespassing by scavengers and vandals.
1.1.2.1 Location
The Site is located at 201 West Oklahoma Avenue in Milwaukee, Milwaukee County, Wisconsin.
1.1.2.2 Description of Threat

2.1.1 Narrative
Additional effort was made on the east side of the building to establish vegetation. Additional assessment and sampling was conducted underneath the building to determine if recoverable PCB oil was present and it may be migrating off Site. Data from this sampling were generated, analyzed and discussed with City of Milwaukee and State of Wisconsin representatives to determine next steps (see Section 2.2.2).
2.1.2 Response Actions to Date
Site activities during the final reporting period included the following:
- Re-seeded and installed erosion controls on the east side of the building;
- Investigated nature & extent of sub-surface contamination in floor drains and under the building foundation;
- Re-secured building windows, doors and perimeter gate; and
- Reviewed, tabulated & presented data from confirmatory sampling to RACM & WDNR (see Section 2.2.2).
In January 2015, EPA was requested by RACM & WDNR to conduct additional investigation of nature & extent of sub-surface contamination and propose next steps or additional activities to address potential off site migration. In April 2015, a ground penetrating radar (GPR) survey was conducted to attempt to identify the potential presence of liquids (PCB or solvent contamination) underneath the building. In May 2015, five borings were advanced through the floor of the building to an average depth of 15-20' to characterized sub-surface features and sample sediments. Though elevated levels of both VOCs and PCBs were found, no significant accumulations of contaminants (oils or solvents) were identified. See the figures in 'documents' section of website for details of data/results.

2.2.2 Issues
A meeting was held between EPA, RACM & WDNR on June 3 to discuss sampling data and determine appropriate next steps. Based on consideration of the sub-surface sampling results, it was decided that no additional work under this removal action should be conducted. However, EPA would consider a request for additional time critical removal action(s) once the building was demolished if requested and warranted to address sub-surface issues.
