This site in Mission, TX is a former pesticide formulation and packaging facility, and was the subject of corrective action by USEPA in 1982. Deterioration of the containment cap has raised concerns over potential health impacts from exposure to chlorinated pesticides.
Contamination of surrounding properties was addressed by previous TCEQ actions.
During the February 7, 2006 site walk, OSC Harris noted a well-used skateboard ramp, increased graffiti across all site buildings, evidence of heavy vehicle traffic on the capped area and accelerated deterioration of the southern portion of the cap in the areas of vehicle traffic. From the August assessment, it is known that the bulk of the detected pesticides are found within three feet of the surface. These factors indicated to OSC Harris that persons and vehicles are frequently and freely entering the site, increasing the failure rate of the cap and potentially being exposed to the chlorinated pesticides within the affected areas.
On Friday February 9, 2006 OSC Harris made a determination that a threat to public health or welfare has developed at this site that requires the initiation of an emergency removal action. The property owner is unable to construct the necessary fence, but consented to EPA doing so. An emergency Task Order was issued, and OSC Harris met with the ERRS contractor and City of Mission representatives at the site on Monday February 13, 2006 to scope and verify the fence construction and location. Installation will begin immediately following HAZWOPER training for the fencing company employees.
ERRS contract firms are developing comprehensive work plans, time lines and cost estimates for the anticipated removal action.
Cleanup standards will reflect the future commercial land use as confirmed by the current landowner and the City of Mission.

Access to site will be restricted by fencing. This will prevent trespass and potential direct exposure to the public.
Continued cap deterioration is evident in areas affected by vehicle traffic. Patching and fencing will control this until removal.
